Sat Sep 7 16:02:09 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* In JOIN notify handling, mark that the cache entry of the
client cannot be expired. Can cause crashes on normal
server (asserts client->channels). Affected file is
silcd/packet_receive.c.
* From now on distribution versions are used as protocol versions
instead of by default using the Toolkit base version as protocol
version. Affected file prepare.
* Do not set the locally resolved hostname for local client
entry but take what server sends. This way the real hostname
is showed in WHOIS for yourself. Affected file is
lib/silcclient/idlist.c and lib/silcclient/client.c.
Sat Sep 7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
* Rewritten check for POSIX threads. Use --with-pthreads[=DIR]
for implied search (not needed on platforms which has native
pthreads library). Use --without-pthreads to disable threads.
Affected file is configure.in.pre
* Fixed --with-iconv on platforms which need to bypass (broken)
native iconv(). Affected file is configure.in.pre
Sat Sep 7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Moved -C option parsing in Irssi SILC client at same time
as other options. The UI was initialized earlier and caused
problems on command line. Bug #16. Affected file is
irssi/src/silc/core/silc-core.c.
Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
* Added global variable silc_log_timestamp that tells silclog
wether to print or not the timestamp in the logging files.
Affected file lib/silcutil/silclog.[ch].
* Added silcd configuration option Timestamp in the Logging
section. Affected file silcd/serverconfig.[ch],
doc/example_silcd.conf.in.
Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>

fingerprint instead of two first bytes when determining
if it is set. Bug #18. Affected file silcd/command.c.
* Fixed duplicate PKCS name registering to not allow it.
Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
* Conditionalize non-gcc compiler optimizations for various
platforms, enable those commented out. Cleanups.
Affected file lib/silcmath/mpi/configure.in
Sat Aug 24 15:11:32 EEST 2002 Timo Sirainen <tss@iki.fi>
* silc_rng_exec_command() left zombie processes if command
didn't generate any output. Affected file
lib/silccrypt/silcrng.c
Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
* Rewrote iconv checking, introduce --with-iconv for systems
which rely on libiconv. Check if iconv() provided by libc
is good enough, otherwise demand libiconv. Affected file
configure.in.pre
Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
* Search for ldopen() also in libc. This enables SIM support
on *BSD systems. Based on patch from Alex Zepeda. Affected
file configure.in.pre
Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
* Don't call AM_CONDITIONAL conditonally for SILC_THREADS.
This fixes prepare on *BSD systems. Affected file
configure.in.pre
Sun Aug 4 15:55:40 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
* More fixed for not having purge timeout for global clients
that are on channel. Affected files silcd/command_reply.c
and server_util.c.
* Fixed the rekey protocol to work with backup router connections.
Rekey packets are now allowed on disabled connections as
well. Affected files silcd/packet_send.c and server.c.
* Do not switch to be as backup router when shutting down and
closing the primary connection. Affected file silcd/server.c.
* Fixed memory leaks in backup router deleting. Added
silc_server_backup_free to free all data during shutdown of

Sun Jul 14 21:33:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Do not process commands if the sock->user_data is NULL.
Affected file silcd/command.c.
Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed buffer overflow and security problems (loosing bits
in CFB encryption) in SILC RNG. Problems reported by

Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Added yet more checks that client is not expired on global
list if it is on channels. Affected file is
silcd/command_reply.c.
Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Merged c0ffee's MIME signal patch which adds support for
sending also MIME messages in Irssi SILC Client, and handling
received MIME messages in a signal (and perhaps doing something
to non-textual MIME messages).
Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed pending command deletion in server and client library
to check the whole list instead of breaking after first found.
The affected files are silcd/command.[ch] and
lib/silcclient/command.[ch].
Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Return NO_SUCH_CHANNEL error in USERS for channel that is
secret or private, otherwise it's possible to find out
whether a secret channel exists or not. Affected file
silcd/command.c.
* If CMODE change fails during the mode setting, assure that
the old mode mask is set for the channel back. Affected
file silcd/command.c.
* Fixed passphrase saving on +a channel on normal server
after successful JOIN command. Affected file silcd/command.c.
Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Remove server/router operator privileges in DETACH command,
since it's possible to resume to server where these
privileges would not be allowed for the client. Affected
file silcd/command.c.
* Do not set to wait for backup in rehash of the server.
Affected file silcd/server.c.
* Do not check listener sockets when counting how many
socket connections we have. Affected file is
silcd/server_util.c.
* Do not announce disconnected clients that are remaining
in history (for WHOWAS). This is because SIGNOFF notify
for these has been sent earlier already. Affected file
silcd/server.c.
Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Buffer overflow with CUMODE command's mode->mode character
conversion. Reported by Ville Räsänen. Affected file
lib/silcutil/silcutil.c.
Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Allow heartbeat packets to go disabled connections anyway.
Affected files silcd/server.c and silcd/packet_send.c.
* Do not broadcast New Channel packets with List flag set
in the packet to backup routers. The router must check
for the correctness of the packets before sending them.
It is possible that router will have enforce Channel ID
change and this would cause desync in the backup router.
Affected file silcd/packet_receive.c.
* Remove SILC_PACKET_FLAG_LIST from the temp packets that
are handled in list parsing. They are not list packets
anymore. Affected file silcd/packet_receive.c.
Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Stop waiting for backup router through the timeout, not
directly after backup router has arrived. Affected file
silcd/server.c.
* Do not re-create channel keys and send them when removing
clients in server shutdown. Affected files are
silcd/server_internal.h and silcd/server_util.c.
* Notify distribution to backup routers was missing from
the silc_server_send_notify_dest function which caused
desyncing problems with backup router. Affected file is
silcd/packet_send.c.
* The client's channel removing was working wrong on
backup router. It assumed that it doesn't know global
information but backup router does know. For this reason
it could remove channel when it wasn't supposed to do that.
Affected file silcd/server.c and silcd/server_util.c.
Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Stop for a couple seconds after badkup router has become
primary router. Affected file silcd/server.c.
* Added silc_server_remove_servers_by_server, which is used
to remove servers originated from some other server. Also
clients of those servers can be removed too. Affected file
silcd/server_util.[ch].
* When removing clients after a server has signed of remove
also all servers behind that server (unless they are known
to be available locally), and send SERVER_SIGNOFF for each
of the server separately. Also the signed off clients are
sent now separately per signed off server. The affected files
are silcd/server.c and silcd/server_util.[ch].
* All servers added with silc_idlist_add_server must always
have both "router" and "connection" pointers set. Otherwise,
bad server entries may be left around in the cache.
Affected file silcd/command_reply.c.
* Do not create the channel key in NEW_CHANNEL packet
processing if the channel is empty. Affected file
silcd/packet_receive.c.
* Completed backup router support for standalone routers.
Supports also servers in the cell that do not use the backup
at all.
Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed a bug in silc_string_regexify which did not add '^'
at the start of each string, and thus the matching was
not explicit. For example ban list iikone@*!*@* would
match also "priikone", which is wrong, it would have to be
*iikone@*!*@* to match also "priikone". Affected
file lib/silcutil/unix/silcunixutil.c.
Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Enable all local server connections before updating client
caches when we've become backup router. Otherwise, signoff
packets may not reach the clients. Affected files are
silcd/server.c and silcd/server_util.[ch].
* Fixed a bug in version string parsing which could crash
the program with specially formatted version string.
Bug reported and patch provided by Ville Räsänen. Affected
file lib/silcutil/silcutil.c.
* Handle the disconnection immediately when DISCONNECT
packet is received in server. Affected file silcd/server.c.
* Primary router now waits a short time (10 seconds) for
backup router connection before accepting any other
connection (except local). Affected file silcd/server.c,
serverconfig.[ch].
* Fixed a crash in client libary in NICK_CHANGE notify when
NICK_CHANGE arrived for client entry we are resolving
currently. Affected file lib/silcclient/client_notify.c.
* Call the sconn->callback completion even if error had
occurred. Start reconnecting always if connection to
primary router fails during backup router protocol.
Affected files silcd/server.c and server_backup.c.
Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Added functions silc_server_send_opers and
silc_server_send_opers_notify to send packets stricly
to operators. Added macro SILC_SERVER_SEND_OPERS macro
to send variable argument notify to operators.
Affected files silcd/packet_send.[ch] and silcd/server.h.
* Removed UMODE rights checking with UMODE_CHANGE notify.
Affected file silcd/packet_receive.c.
* Server/router operator now receives notify when network
switches to backup router and when it resumes the use of
primary router. Affected file silcd/server.c and
silcd/server_backup.c.
* Fixed the updating of client information after backup
resuming protocol is over; update all except local clients
to the new primary router. The affected file is
silcd/server_util.c.
* Added support for closing active connections in rehash
that were unconfigured by the user. Supports currently
closing server and router connections. Affected file
silcd/server.c.
* Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
is NULL since seems that on some platforms NULL is allowed
and on some it's not. Fallback encoding is used instead.
Affected file lib/silcutil/silcstrutil.c.
* Fixed statistics updating for incoming server connection
which could cause problems when re-connecting. Affected
file silcd/server.c.
* Preliminary backup router support for standalone router
added. Affected files in silcd/.
* Mark server connections in backup router disabled before
and after backup protocol. Affected file is
silcd/server_backup.c.
* Added support for reconnecting to remote server connection
even if the protocol fails, and if the configuration wants
us to keep trying to connect anyway.
Server connection is not allowed to backup router if
backup router does not have connection to primary router yet.
Affected file is silcd/server.c.
Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Added silc_client_udpate_server function to update changed
server info. Affected file lib/silcclient/idlist.[ch].
* Added check for server entries that are being resolved when
notify is received. If being resolved, handle the received
notify only after it's resolved so that all notifys are
handled in same order as received from the server.
Added similar resolver check to channel entries. Every
notify that cause resolving of any information that affects
channel entry marks the channel entry in waiting state.
After whatever resolving is over the waiters are signalled
and only then the notifys are handled in the same order
as delivered from the server.
Affected files are lib/silcclient/idlist.[ch], and
client_notify.c.
* Fixed KILLED notify handling in normal server. Affected
file silcd/packet_receive.c.
* Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
is locally connected, or was locally connected (but may
be detached and connection is not active). Added also
SILC_IS_LOCAL for checking this status. Affected files
silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
silcd/server.c and silcd/server_internal.h.
Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Don't send or handle TOPIC_SET if topic is already set and
is same as being set. Affected files silcd/command.c and
silcd/packet_receive.c.
* Fixed CMODE change rights checking to work correctly when
removing modes by operator. Affected file is
silcd/server_util.c.
* Fixed some handling with New Channel packet in router and
fixed some CMODE_CHANGE notify handling in server and router.
Affected file is silcd/packet_receive.c.
* Changed "disconnect" client operation to include the
reason of the disconnection and optional disconnection
message. Affected file lib/silcclient/silcclient.h.
* Made the compilation of lib/contrib/ stuff conditional.
Affected files configure.in.pre, lib/contrib/Makefile.am.
Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
to the sender of the notify too, to avoid situation where two
notifys are in the network at the same time going to oppsite
directions. Affected file silcd/packet_receice.c.
Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Delete the client from channel even if the cilent->id is
NULL. It was possible that client was deleted without
removing from channels (theoretically at least). Affected
file silcd/server.c and silcd/server_util.c.
* Free the client data too when resuming is not successful.
Affected file silcd/packet_receive.c.
* Merged some code from c0ffee's silc-plugin. Affected files
irssi/src/silc/core/silc-channels.c and silc-expandos.c.
* Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
to the primary router connection, the other one returns
TRUE if packet must be broadcasted to network.
* All notifys that are destined to primary router (to network)
are now automatically sent to backup routers even if the
router is standalone (and has backup router). Affected files
in silcd/.
* Added --without-irssi and --without-silcd configuration
options for disabling the compilation of these applications.
Affected file configure.in.pre and prepare.
Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Implemented SILC_STRING_BMP and SILC_STRING_UNIVERSAL for
UTF-8 encoding and decoding. Added also new encodings
SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
Added also SILC_STRING_LANGUAGE which is language and charset
specific encoder and decoer for those platforms that support
iconv(). It can convert the UTF-8 to and from the locale
specific character set.
Affected file lib/silcutil/silcstrutil.[ch].
* Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.
* Added function silc_get_command_name to the file
lib/silcutil/silcutil.[ch].
* Improved the server debug output a bit. Affected files are
in silcd/.
Wed Jun 19 17:46:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Save the channel passphrase when received succesful JOIN
command reply from router, on normal server. Otherwise
joinig +a channels from normal server is not possible.
Affected file silcd/command.c.
* Fixed a bug in TOPIC_SET notify handling. The notifier
may be other than client too, like server or channel.
It expected it to always be only client and ignored the
notify. Affected file silcd/packet_recieve.c.
* Removed some (unnecessary) debug printing from
lib/silccore/silcid.c and lib/silccore/silcargument.c.
* Do not force CMODE_CHANGE when server is announcing new
channel.
Router announces stuff only after server reannounces channel
after CHANNEL_CHANGE notify.
These fixes optimizes the announcing procedure, and perhaps
fixes some problems too. Affected file silcd/packet_receive.c.
* Fixed SERVER_SIGNOFF sending to local clients. It was
totally broken and sent the notify to all local clients,
instead of only to those that was on same channel as the
signing off clients. Affected file silcd/server_util.c.
* Added -D option to server. It can be used to give debug
level. The levels are from 0 - 99, and are predefined for
smooth server debugging. (see silcd.c for the predefined
levels). Affected file silcd/server.c.
Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed a bug in Irssi SILC client to close the connection
properly when disconnecting from server. Affected file

channel. Affected file silcd/command.c.
* Better checking for founder mode setting when CUMODE_CHANGE
notify is received. Affected file silcd/packet_receive.c.
* Close all connections when shutting down the server by sending
DISCONNECT packet. Close all listeners too when shutting
down the server. Affected file silcd/server.c.
* Handle DISCONNECT packet correctly in client library by
calling the "disconnect" client operation. Affected file
lib/silcclient/client.c.
* Handle local errors correctly during resuming. Affected
file lib/silcclient/client.c.
Tue Jun 18 10:26:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

lib/silcutil/silclog.c. Fixed memory leaks too.
* The scheduler now dispatches all pending timeout tasks
when it is uninitialized with silc_schedule_uninit.
Affected file lib/silcutil/silcschedule.c.
Mon Jun 17 21:30:55 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

files around the tree.
* Reverted back a fix made to CUMODE which broke it.
Affected file silcd/command.c.
Sun Jun 16 11:49:45 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Added SILC_MESSAGE_FLAG_UTF8 to the protocol specs and the
core library, and implemented it. All textual messages SHOULD
use this flag and the message MUST be UTF-8 encoded.
All text messages sent by Irssi SILC client are now UTF-8
encoded (regardless whether the terminal supports UTF-8 or not).
Affected files are lib/silccore/silcchannel.h,
irssi/src/silc/core/silc-servers.c, silc-channels.c and
client_ops.c.
Sat Jun 15 18:23:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Added lots of new statistics updating that was missing from
the server and router code. Affected files in silcd/.
* Sending SIGUSR1 signal to server now dumps the current
server statistics into /tmp directory. Affected file is
silcd/silcd.c.
* ROBODoc documented the lib/silccrypt/silchash.h. Improved
the SILC Hash Interface also. Added new functions
silc_hash_get_name, silc_hash_init, silc_hash_update and
silc_hash_final. Affected file lib/silccrypt/silchash.c.
Sat Jun 15 12:09:14 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Added some better info printing for client during connecting.
Affected file silcd/server_util.c.
* Implemented the SILC_CHANNEL_UMODE_QUIET mode that can be used
to silence a user on a channel. Affected files are
lib/silcclient/client_channel.c, irssi/src/silc/core/client_ops.c,
irssi/src/fe-common/silc/module-formats.[ch], silcd/command.c
and silcd/packet_receive.c.
* Fixed a fatal bug in handling of malformed command payload.
Affected file silcd/command.c.
* Fixed a double free when announcing channel users to router.
Affected file silcd/server.c.
* After successful authentication to channel founder mode, check
that there isn't anyone else with founder mode on the channel.
The one that authenticated will become founder and anyone
else is demoted. Affected file silcd/command.c.
* Added error printing of any error that has occurred during
any command in client library. Affected file is
irssi/src/silc/core/client_ops.c.
* Removed some error printing from the client library and left
it for the application to worry (from the error status it
receives in 'command' client operation. Affected file is
lib/silcclient/command.c.
Fri Jun 14 22:59:02 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Added new status types KEY_AGREEMENT_ALREADY_STARTED and
KEY_AGREEMENT_SELF_DENIED to lib/silcclient/silcclient.h.
Starting key agreement with itself is denied. Affected file
is lib/silcclient/client_keyagr.c.
* Fixed some error checkings from the SFTP library which caused
misbehaviour. Affected files are lib/silcsftp/sftp_client.c
and lib/silcsftp/sftp_util.c.
* Added new "debug" and "debug_string" settings to Irssi SILC
client which can be used to print runtime debugging on the
Irssi's screen. Available when compiled with --enable-debug
option. Affected file irssi/src/silc/core/silc-core.c.
Tue Jun 11 16:36:02 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>

caused server crash when a non-allowed connection arrived.
Reported by Richard Becker. Affected file silcd/server.c.
Mon Jun 10 16:29:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Added WATCH list sending to backup routers from router.
The WATCH command is sent by the router to the backup
router. Affected file silcd/command.c.
* Mark the backup_router flag for RouterConnection entry
if the backup router stuff is defined in the config file.
Affected file silcd/serverconfig.c.
* Fixed some backup data sending around the code to work better
if the router is standalone router. Not all places were fixed.
Affected file silcd/packet_receive.c, silcd/packet_send.c,
silcd/server.c.
* Fixed the router connecting when connecting to multiple
routers. It ignored every other router except the first
one. Affected file silcd/server.c.
Mon Jun 10 09:28:21 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Made the private key generation after expiration optional.
If not created after expiration the old key will re-expire
at a later time (and thus key pair is not necessary to
change). Affected file irssi/src/silc/core/clientutil.c.
Sun Jun 9 18:58:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* The length arguments in bind() and connect() were wrong
and fixed now to used SIZEOF_SOCKADDR in the
lib/silcutil/unix/silcunixutil.c.
Tue Jun 4 18:36:05 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed detach timeout handling to use Client ID and not
the actual client entry which may be freed in the callback.
Affected file silcd/command.c.

the packet, ignore the packet since it cannot be decrypted.
Affected file lib/silcclient/client_prvmsg.c.
Thu May 23 12:00:14 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
* When resuming client, remove the old client entry from
the watcher list too. Affected file silcd/packet_receive.c.
* Do not allow normal server to force founder mode away
from router if the founder mode is already set. Affected
file silcd/packet_receive.c.
* Remove the client entry with watch notify types with short
timeout, and not directly, so that other notifys can be
retrieved too. Affected file lib/silcclient/client_notify.c.
* Display notification about data messages that cannot be
displayed. Affected files irssi/src/silc/core/client_ops.c,
irssi/src/fe-common/silc/module-formats.[ch].
Sun May 19 18:59:00 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

get_home_dir to Irssi routines. Affected files are
irssi/src/core/misc.[ch] and irssi/src/core/core.c.
Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Made some structure optimizations. SFTP memory FS MemFSEntry
entry structure. Optimized SilcTask structure. Optimized
SilcPacketContext structure.
Affected files lib/silcsftp/sftp_fs_memory.c,
lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* And yet again reverted back the config thing since Johnny
screwed it up. Affected file silcd/serverconfig.[ch], server.c,
and silcd.c.
* Fixed memory leaks from config object. Affected files are
silcd/serverconfig.[ch].
* Added support for adding new connections to the server in rehash.
After rehash they take effect.
Added support for changing the maximum allowed connections in
rehash. The number can grow but going smaller is not supported.
Added function silc_server_num_sockets_by_remote to the
silcd/server_util.[ch].
Affected files are silcd/server.c, and silcd/serverconfig.[ch].
Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
* Added preliminary checking during config parsing for a valid
public/private key and removed further checks in the code.
Affected files are silcd/serverconfig.[ch], server.c.
* Moved functions silc_server_drop() and silc_server_daemonise()
from server.c to silcd.c since they are stricly related to
the application activity.
* Reverted a small part of the automatic ref/unref since
it caused a double unref in some situations. Affected
files are silcd/silcd.[ch], server.c, serverconfig.c.
* Added some .cvsignore files in the lib directory.
Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed silc_net_gethostbyaddr to correctly resolve by
address. Affected file lib/silcutil/silcnet.c.
* Fixed the notify relaying to client. The HMAC to be used
with relayed packets ws wrong and caused decryption failure
at the client end. Affected file is silcd/packet_receive.c.
Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Created new branch silc_protocol_1_0_branch.
* Reverted the silc_log_quick change in lib/silcutil/silclog.c.
* Changed the silc_server_config_* routines to be SilcServer
independent. They are now officially application specific code
and not part of generic server implementation. Affected files
are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Added automatic referencing of config context in the
silc_server_config_alloc, and automatic unreferencing in the
silc_server_config_destroy. Affected files are
silcd/serverconfig.[ch], silcd/silcd.c.
* Fixed the silc_log_quick handling in the logging routines.
It didn't log quickly when it was TRUE. Affected file is
lib/silcutil/silclog.c. Also the flush delay was set even
if it was 0 in config file. Affected file is
silcd/serverconfig.c.
* Added support for changing key pair of the server in rehash.
Affected file silcd/server.c.
Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed the TOPIC_SET notify to not cras. It changed the topic
too early, before getting the channel entry. Affected file
is silcd/packet_receive.c.
Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
* Added functions silc_server_config_[ref/unref], these are used
to prevent that the config object is destroyed.
No longer directly affect global variables silc_log_quick and
silc_log_delay, they are first cached inside the config object
and then applied with silc_server_config_setlogfiles().
silc_server_config_set_defaults() is now internal to
serverconfig.c, there are no reasons to show this internal stuff
to the server.
Affected files are silcd/serverconfig.[ch].
* Added macro SILC_SERVER_LOG_STDERR(), this should replace most
fprintf's to stderr, since some code may be executed again after
the server went into the background. Affected files are
silcd/server.[ch].
* Added rehash support. Added function silc_server_rehash() that
will perform all the basic tasks of the rehashing procedure.
* Added command line option `-x, --hexdump'. This will enable the
SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
The option `--hexdump' implies `--debug'.
* Fixed a bad bug in the logging APIs (silcutil library) where
the application would crash after calling silc_log_reset_all().
Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed the KICKED notify handling in client library to
correctly remove the channel and all entries from the
channel when I was kicked. This bug crashed the client.
Fixed yet another but in KICKED notify handling to remove
the kicked client correctly from the channel.
Affected file is lib/silcclient/client_notify.c.
* Fixed a minor bug in looking up correct client entry
in KICKED notify in server. Affected file is
silcd/packet_receive.c.
* Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
sources correctly to distribution. Fixes --with-gmp option.
* Removed the manual rehashing from ID Cache, and changed it
to use the SILC Hash Table's auto rehash feature. Affected
file is lib/silccore/silcidcache.c.
Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed a bug in the silc_client_nickname_format function that
handles the multiple same nickname formatting. Two clients
with same nickname caused problems after the first one left
and rejoined. It didn't format the nickname correctly.
Affected file is lib/silcclient/idlist.c.
Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
* Don't change the topic if olod topic is same as new one.
Affected file is silcd/packet_receive.c.
Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Added cross-reference support to the SILC Documentation
generator. All types across all HTML files are now cross-
referenced. Affected files util/robodoc/generator.c and
scripts/silcdoc/silcdoc.
* Added file lib/silcutil/silctypes.h to include all the
arithmetic type definitions and some macros. Removed
includes/bitmove.h and moved macros to silctypes.h.

* Merged bugfixes for Irssi SILC client from irssi.org CVS.
Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Added `type' argument to silc_id_payload_parse_id function which
now returns the type of the ID to the sent pointer. Affected
file is lib/silccore/silcid.[ch].
* Added check for CMODE_CHANGE notify type that mode change is
allowed by the sender. Affected file silcd/packet_receive.c.
* Added check for CUMODE_CHANGE notify type that mode change is
allowed by the sender. Affected file silcd/packet_receive.c.
Added the ID type as CUMODE_CHANGE notify type as argument
to the `notify' client operation. Affected files are
lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
* Added function silc_client_add_server to the client library.
Added support for resolving also channel and server info when
received unknown entity in notify packet. Affected files are
lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
* Added function silc_command_get_status to return the command
status from the command reply's argument payload. Affected files
are lib/silccore/silccommand.[ch].
* Added check for KICKED notify type that the kicking is
allowed by the client. Affected file silcd/packet_receive.c.
* Created function silc_get_input which can be used to get input
(echo on or off) from user on command line. Affected files are
lib/silcutil/silcutil.[ch].
Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Optimized silc_server_packet_relay_to_channel function.
Added new function silc_channel_message_payload_encrypt which
can be called directly if channel message payload needs to
be encrypted and is already encoded (no need to call _encode
function). Packet relaying is now done by router without any
extra memory allocations. Affected files are
lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
silcd/packet_send.c.
* Fixed the INVITE notify handling. It took wrong arguments
as invite list and invite delete. Affected file is
silcd/packet_receive.c.
* Added check for TOPIC_SET notify type that the topic change is
allowed by the client. Affected file silcd/packet_receive.c.
* Added check for INVITE notify type that inviting is allowed by
the client. Affected file silcd/packet_receive.c.
* Changed the silc_server_client_on_channel to return the
SilcChannelClientEntry as well. Moved the function
silc_server_check_cmode_rights to server_util.[ch].
Affected files are silcd/server_util.[ch], silcd/command.c.
* Added function silc_server_check_umode_rights to check whether
changing client's user mode is allowed. Added check for
UMODE_CHANGE notify type that the umode change is allowed
by the client. Affected files are silcd/server_util.[ch],
silcd/packet_receive.c and silcd/command.c.
Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
ID length. It ignored that ID can be IPv6 based as well.
Affected file lib/silccore/silcpacket.h.
* Fixed the silc_id_id2str and silc_id_str2id to take the
IPv6 address offset's into consideration. Affecte file is
lib/silccore/silcid.c.
Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed the internal Unix scheduler functions to check for
NULL context they may receive. The affected file is
lib/silcutil/unix/silcunixschedule.c.
Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
* Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
can specify different directory with --home command line
parameter. Affected files irssi/src/silc/core/client_ops.c,
clientutil.c
* SILC-specific commands aren't now executed if the active server
isn't of SILC-type, so there won't be problems with having
IRC and SILC protocol support in same client. Affected files
irssi/src/silc/core/silc-channels.c, silc-servers.c,
silc-commands.h
Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
* Improved the signal support in SILC Schedule. Added new
function silc_schedule_signal_call which is used by application
to mark a signal to be called. It is now safe to perform
any kind of tasks in signal callbacks since it is guaranteed
that the application specified signal callback is called
after the signal is over. Affected files are
lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Added `name' field to SilcChannelPrivateKey to represent
application given name for the key. Moved also the context from
lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
Added the `name' argument also to the function
silc_client_add_channel_private_key.
Added function silc_client_current_channel_private_key to set the
current channel private key in use.
Added "change" command to KEY command which can be used to change
the current channel private key. Bound the command also to
alt+K (Alt+Shift+k).
Also affected files lib/silcclient/client_channel.c,
irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
* Added silc_rng_get_byte_fast function in to the
lib/silccrypt/silcrng.[ch].
* Changed the interface of silc_packet_assemble and the
silc_packet_send_prepare. If silc_packet_assmble is now
called the application does not call silc_packet_send_prepare
because the library will call it automatically. These
interfaces now also return a reference to the outgoing buffer
which includes the assembled packet, which the application can
use to encrypt the packet.
Affected files are lib/silccore/silcpacket.[ch],
lib/silcclient/client.c, client_channel.c client_prvmsg.c,
silcd/packet_send.c, server_backup.c and packet_receive.c.
* Fixed a packet sending bug on very high load, where outgoing
packet queue wasn't handled correctly and packets got corrupted.
Affected files are lib/silcutil/*/silc*sockconn.c,
lib/silcclient/client.c and silcd/server.c.
Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Added macro SILC_PACKET_DATALEN which can be used during
packet assembling to check whether the data to be added to
the packet will fit to SILC_PACKET_MAX_LEN. If not the data
len is truncated until it fits it.
Added checks for maximum length of channel message payload and
private message payload also.
Added checks for maximum packet length in server and in
client library.
Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
lib/silcclient/client.c, lib/silccore/silcchannel.c and
lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
lib/silcclient/client_prvmsg.c.
Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
* Added silc_server_packet_queue_purge call to the
silc_server_disconnect_remote to assure that all data in the
queue before disconnecting is sent to the network. Affected
file silcd/server.c.
Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Added the deleting of server's own ID cache entry to the
silc_server_free function. Free also everything else that
has been allocated in silc_server_init. The affected file
is silcd/server.c.
Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Added functions silc_parse_version_string, silc_version_to_num,
and silc_ske_parse_version to parse SILC protocol style version
strings. Affected files lib/silcutil/silcutil.[ch] and
lib/silcske/silcske.[ch].
* Added new configuration params: version_protocol, version_software
and version_software_vendor to specify what version the remote
host must at least be to be able to connect to server. The vendor
string can be regex matched too. Added new function
silc_server_connection_allowed to check maximum number of allowed
connections, and allowed versions for incoming connections.
Affected files are silcd/server.c, server_util.[ch] and
serverconfig.[ch].
Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Added preliminary support for signals in scheduler. The
signals we care about are now blocked always when the scheduler
is locked. This way we can synchronise the use of signal with
scheduler. It is guaranteed that when signal occurs the scheduler
is not locked, and thus new tasks can be safely added to the
scheduler.
Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
to silc_schedule_internal_init and silc_schedule_internal_uninit.
Added new platform specific routines
silc_schedule_internal_signals_[un]block and
silc_schedule_internal_signal_[un]register.
Added new functions to SILC Schedule API:
silc_schedule_signal_[un]register. Each signal that application
is going to use should be registered to the scheduler.
Affected files are lib/silcutil/silcschedule.[ch],
lib/silcutil/*/silc*schedule.c.
Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Check for unauthenticated client and server in the
silc_server_new_client and silc_server_new_server functions.
Affected file silcd/packet_receive.c.
* Added function silc_string_is_ascii to check whether given
string is 7-bit ASCII string. Affected files are
lib/silcutil/silcutil.[ch].
* Added function silc_id_is_valid_server_id into the
silcd/serverid.c and added checking for valid Server ID's in
silc_server_new_server. The Server ID must always be based
on the server's public IP address.
* Added logging of DISCONNECT packet message in the server.
Affected file silcd/server.c.
Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Changed all library interfaces that use Global RNG to also
accept SilcRng as argument. Affected files are
lib/silcclient/command.c, lib/silccore/silcauth.[ch],
lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
silcd/packet_send.c, lib/silccore/silcprivate.[ch],
lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
lib/silccrypt/rsa.c.
* Added function silc_pkcs_generate_key to the
lib/silccrypt/silcpkcs.[ch] for applications so that they
don't need to do pkcs->pkcs->init calls anymore.
* Remove SilcSocketConnection from the SFTP API since it really
wasn't needed there. The application has the information
saved in its contexts anyway and the SFTP layer doesn't need
know about it. Affected files lib/silcsft/silcsftp.h and
lib/silcsftp/sftp_[server/client].c.
* Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
The SilcSimContext is not SilcSim.
* Fixed possible buffer overflows in silc_id_render in the
lib/silcutil/silcutil.c.
* On EPOC the global crypto module lists are not used at all
in the crypto library. Added support for using the constant
algorithm list on EPOC. Affected files are
lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
silcpkcs.c.
* Fixed the handling of third parameter of KICKED notify, since
it was mistakenly updated to SILC Protocol 1.0 even though it
is to be included in 1.1. Since it is not in 1.0 it is not
mandatory, and this fix now handles it only if it is provided,
and it is not error if it is not provided. Affected file
lib/silcclient/client_notify.c.
Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
client. Affected file irssi/src/silc/core/client_ops.c.
* Merged with Irssi 0.8.4 from irssi.org CVS.
Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
* Check for valid socket connection in client entries before
sending any messages. Fixes a crash, but doesn't fix some
other underlaying bug that is lurking there. Affected
file silcd/packet_send.c.
Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
* $usermode, $cumode and $cumode_space expandos shouldn't do
anything with non-SILC server records. Affected file
irssi/src/silc/core/silc-expandos.c
Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed the silc_net_check_[host/local]_by_sock to support
IPv6 bound sockets as well. Now they can return IPv6 addresses
as well. Affected file lib/silcutil/silcnet.c.
* Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
Affected lib/silcutil/unix/silcunixnet.c.
* Fixed ID rendering (at least on some platforms, not NetBSD)
for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Added silc_hash_public_key and silc_hash_public_key_compare
functions to be used with SilcHashTable. They can be used to
hash public keys and compare public keys in hash table. Affected
file lib/silcutil/silcutil.[ch].
* Added support for specifying multiple public keys for Client
connection section in server configuration file. This makes it
possible to accept multiple public keys from same host, or to
make a section that accepts any incoming host, and have the
accepted public keys listed in the section.
Added functions silc_sever_[find/get]_public_key, added the
support for this actually to all connection sections but only
the Client section is currently allowed to specify multiple
public keys.
Affected files are silcd/server.c, server_internal.h,
command.c, protocol.c, server_util.[ch], packet_receive.c.
Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Merged Irssi 0.8.2 from irssi.org CVS.
Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
* If silc_debug is TRUE, also output standard logging messages
to stderr with the debug output.
Made silc_log_reset_all() flushing all channels before returning.
Also fixed some documentation typos.
Affected files are lib/silcutil/silclog.[ch].
Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed the server to check correctly the amount of connections
from single host, by checking also the type of the connection.
Fixed also the comparison of number of connections and number
of allowed connections. Affected files are silcd/server.c,
server_util.[ch].
Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed the USERS command reply to save the user's mode on the
channel as well. Fixed JOIN command reply to check whether a
client is on channel already and not join it twice. Affected
file lib/silcclient/command_reply.c.
* Added new file silc-expandos.c into irssi/silc/core/ to return
various stuff for various signal for the statusbar etc. updating.
Now Irssi SILC client prints channel user modes etc. on the
statusbar.
* The user mode (like server/router operator changes) is now shown
on the Irssi SILC client's statusbar. The affected files are
irssi/src/silc/core/client_ops.c, silc-expandos.c.
Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>

file lib/silcsftp/sftp_fs_memory.c.
Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed the buffer formatting and unformatting routines to
check the size of 64 bits types with sizeof(). Affected
file is lib/silcutil/silcbuffmt.c.
Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Removed 0.6.x backwards support.
Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Changed all integer type names:
[u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
to avoid collisions with other libraries using same type names
as we did.
Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Added `prefer_ipv6' argument to the functions
silc_net_gethostbyname[_async]. If it is TRUE it will return
IPv6 address over IPv4. If FALSE IPv4 address is returned
even if IPv6 address was found. Affected files
lib/silcutil/silcnet.[ch].
* Added support silc_net_create_connection[_async] to fallback
to IPv4 address if IPv6 address could not be used (like if
it doesn't work on a specific system). Affected file in
lib/silcutil/unix/silcunixnet.c.
Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Added silc_schedule_reinit function to do the enlarging
of the max tasks handling capabilities of the scheduler.
Affected files lib/silcutil/silcschedule.[ch].
Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Added automatic extern "C" { ... } for C++ compilers so the
application does not need to define them. Affected file
includes/silcincludes.h.
* Renamed lib/silcclient/silcapi.h to silcclient.h as the
old name went against naming convention. Applications now
include "silcclient.h" instead of "clientlibincludes.h".
Removed includes/clientlibincludes.h, it is redundant now.
* Renamed includes/version.h to silcversion.h.
* Added really preliminary support for OS/2 into the util
library. Only thread & mutex API is implemented, others
are still to be implemented. Created the lib/silcutil/os2/
directory. Created also file includes/silcos2.h.
Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

functions to support SILC on BeOS. Created also file
includes/silcbeos.h.
Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
* Added proper initializations to silc's irssi code, so it's
now possible to load it as module. Affected files
irssi/src/silc/core/silc-core.c,
fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Merged latest Irssi (0.8.1) from the irssi.org's CVS into
the SILC tree.
* Fixed the silcdoc document generator to correct generate
docs from all kinds of filenames. Affected files are
util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
* ROBOdoc documented lib/silcutil/silcmemory.h.
Added also new function silc_memdup.
* Removed lib/silcutil/silcbufutil.h and moved those routines
to the lib/silcutil/silcbuffer.h.
Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Added `user_count' to the SilcChannelEntry which now tells the
number of users on the channel. The user count is now saved
in normal server of global channels as well. Affected files
silcd/server.c, idlist.h, packet_receive.c and command.c.
* Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
include file utility functions.
* Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
instead of calling directly OS routines.
* Fixed NICK change printing in Irssi SILC Client. Fixed
KICKED notify printing in Irssi SILC Client. Affected file
irssi/src/silc/core/client_ops.c.
* Fixed a NICK change bug in client library, to not recreate the
client_entry->channels hash table everytime nick is changed.
Affected file lib/silcclient/client.c.
Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* ROBOdoc documented the lib/silcske/silcske.h, and improved
the SKE interface a bit.
* Fixed padding problem in PKCS#1. The padding was not actually
random since the random number generator was used incorrectly.
This security bug affects only when encrypting with PKCS#1, and
it is not currently used at all in SILC. SILC only use signing
with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Rewrote the notify handling in Irssi SILC client to not call
the events as signals. Fixes problems with Perl support.
Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
* Send the auto-nicking NICK command in client library with
little timeout after connecting. The affected file is
lib/silcclient/client.c.
* Added following new config file settings:
channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
key_exchange_timeout, conn_auth_timeout, connections_max,
links_max.
Implemented all the new config settings handling in the server.
Optimized the use of SKE Mutual flag usage. Use it only
if connection authentication protocol is not based in public
key authentication.
Renamed all SilcServerConfigSection* to SilcServerConfig*
to have a bit shorter names.
Affected files silcd/serverconfig.[ch], server.[ch], and
protocol.[ch].
Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
* Cleaned up the listening sockets code, preparing for the rehash
support. Affected file is silcd/server.c.

and silcd/server.c.
Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Create lib/doc/silcrng_intro.html document as introduction
to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
* Fixes to the silcd config template. Affected file is
doc/example_silcd.conf.in.
* Removed type casts from silc_calloc(), conforming to the
CodingStyle. Affected file is lib/silcutil/silcconfig.c.
* Removed param_name member from client, server, and router
section structs, now identifying the param directly.
Added CONFIG_FREE_AUTH macro in config file parsing.
Affected files are silcd/serverconfig.[ch].
Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
* Fixed command line parameter handling. All SILC initialization
is now done in silc_core_init() which also fixes autoconnecting
to servers.
Affected files irssi/src/silc/core/silc-core.c,
irssi/src/fe-text/silc.c.
Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Added new configuration options and blocks:
keepalive_secs, reconnect_count, reconnect_interval,
reconnect_interval_max, reconnect_keep_trying and
require_reverser_lookup. Added ConnectionParam block, and
implemented the connection parameters when connecting as
initiator and when accepting connections as responder.
Added CONFIG_IS_DOUBLE macro in config file parsing, to check
whether given configuration value has been given already.
Affected files silcd/serverconfig.[c], server.[c].
* Splitted the doc/example_silcd.conf.in. Separated the crypto
algorithm parts and created new file silcalgs.conf, that
is now included from the example_silcd.conf.in.
* Optimized the silc_server_connect_to_router_second to take
the connection configuration object from the SilcServerConnection
object instead of finding it during the connecting phase.
Added the configuration object to SilcServerConnection struct.
Affected files silcd/server_internal.h, server.c.
Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
* Add the client on channel after it was resolved at the
channel message receiving, and it was not already on the
channel. Affected file lib/silcclient/client_channel.c.
Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed the public key authentication to allocate always the
destination signature buffer instead of using static buffer.
Affected file silcd/protocol.c.
Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Unified the serverconfig.[ch]'s helper function interface.
Affected file silcd/serverconfig.[ch].
* Removed doc/example_silc.conf.in since it is redundant.
The make install will now install irssi/silc.conf file.
* Added new Passphrase and Publickey authentication methods to
config file, allowing both public key and passphrase based
authentication to be set at the same time.
Added `prefer_passphrase_auth' setting in config file which
can be used to set to prefer passwd auth if both passwd and
public key is set. If not set, public key is preferred.
This has effect only when being initiator (responder will try
both anyway).
Added support for authentication with passphrase and public key
at the same time. The passphrase is tried first always since
it is faster to check.
Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
* Merged the new SILC Config library, with the server parsing
support. Read the header file silcconfig.h or the toolkit

Payload. Affected file lib/silccore/silcchannel.c.
* Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
as header filenames.
* Removed lib/silcclient/README and created HTML file
lib/silcclient/silcclient_using.html, which is now included
as part of Toolkit documentation.
Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed CUMODE_CHANGE notify handling to change the mode of
correct client. Affected file lib/silcclient/client_notify.c.
* Make silc_rng_alloc fail if it cannot allocate the sha1
hash algorithm. Affected file lib/silccrypt/silcrng.c.
Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed the file transfer's key agreement payload to include
zero port also if the hostname is NULL because it could not
be bound.
Call file transfer monitor callback now also if error occurs
during key agreement protocol.
Changed the silc_client_file_send interface to return the
SilcClientFileError instead of session id. The session ID
is returned into pointer provided as argument.
Check that the file exists locally before sending the
file transfer request at all.
Affected file lib/silcclient/client_ftp.c, silcapi.h.
* Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
error than can occur while key agreement protocol. Affected
file lib/silcclient/silcapi.h.
* Fixed the event_mode CMODE handler to not crash when mode
is changed and +k mode is set in the channel. Affected file
irssi/src/silc/core/silc-channels.c.
* Fixed SILC_LOG_ERROR to give out Error and not Warning, and
SILC_LOG_WARNING to give out Warning and not Error. Affected
file lib/silcutil/silclog.c.
* Fixed the channel message payload decryption in the function
silc_channel_message_payload_decrypt to not modify the original
buffer before it is verified that the message decrypted
correctly. Otherwise, next time it is called with correct
channel key it won't encrypt since the payload is corrupted.
Affected file lib/silccore/silcchannel.c.
Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Do not constantly resize the window. A fix patch by cras.
Affected file irssi/src/fe-text/screen.c.
Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
Affected file lib/silcutil/silcnet.c.
Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed a bug in hash table internal routine for traversing
the table with foreach callback. The current entry may
become invalid in the callback but it was referenced after
the callback returned.
Do not allow auto rehashing of hash table during the
silc_hash_table_foreach operation, for same reasons as it is
not allowed for SilcHashTableList. Affected files are
lib/silcutil/silchashtable.[ch].
Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
* Defined DLLAPI into silcincludes.h and silcwin32.h for
Win32 DLL. extern's in header files are now declared with
DLLAPI.
Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed private message handling. It used some old code that
caused the client to crash. Affecte file is
lib/silcclient/client_prvmsg.c.
Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Added function silc_client_add_channel,
silc_client_replace_channel_id, and removed functions
silc_client_new_channel_id and silc_idlist_get_channel_by_id
from client library.
* Added cross reference of the joined channels to the
SilcClientEntry, and changed the SilcChannelEntry's
users list to SilcHashTable. The affected files are
lib/silcclient/idlist.[ch].
* Fixed a bug in hash table tarversing. While the hash table
is traversed with SilcHashTableList the table must not be
rehashed. It is now guaranteed that auto rehashable tables
are not rehashed while tarversing the list. Also defined that
silc_hash_table_rehash must not be called while tarversing
the table. Added function silc_hash_table_list_reset that must
be called after the tarversing is over. The affected files are
lib/silcutil/silchashtable.[ch].
* Changed all hash table traversing to call the new
silc_hash_table_list_reset in server and in client library.
* Added function silc_client_on_channel to return the
SilcChannelUser entry if the specified client entry is joined
on the specified channel. This is exported to application as
well. Affected files lib/silcclient/client_channel.c, silcapi.h.
Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed founder regaining problem with JOIN command on normal
server. The notify for mode change must be sent always and
not only if !cmd->pending. Affected file silcd/command.c.
* Fixed the WHOWAS command's reply sending to support the
lists correctly. Affected file silcd/command.c.
Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
* When sending JOIN command to router for processing the
sender's old command identifier was not saved back to the
sender's command context, fixed now. The affected file is
silcd/command.c.
* Create the key in JOIN command of the router did not return
the channel key, added check for this. Affected file is
silcd/command.c.
* Fixed a channel ID update bug in JOIN command reply. Do
not directly upgrade the ID but call the function
silc_idlist_replace_channel_id if the ID was changed.
Affected file silcd/command_reply.c.
* Fixed memory leaks from command calling if it would fail.
Affected file silcd/command.c.
Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Applied patches from cras:
Memory leak fixes around libaries, irssi window resize fix,
new silclist.h and silcdlist.h, all extern inline changed to
static inline.
* Removed dotconf from lib/dotconf, not needed anymore.
* Removed TRQ from lib/trq, not needed anymore.
* Do more frequent heartbeats (5 minutes instead of 10 minutes)
with server connections. Later this will be configurable
in config file after new config file is done. Affected file
silcd/server.c.
Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed a crash in server related to channel announcements.
Affected file silcd/server.c.
Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed memory leaks in silc_server_create_new_channel*
functions. Affected file silcd/server.c.
* Fixed the CHANNEL_CHANGE notify to re-announce the channel
which ID was changed. This way the router will send the
user list for the channel again, and server won't be in
desync in some rare circumstances. Affected file is
silcd/packet_receive.c.
Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Check for NULL socket pointer in the function
silc_server_packet_send_to_channel_real. Affected file
silcd/packet_send.c.
* Fixed the BAN notify handling to correctly remove ban
list. Affected file silcd/packet_receive.c.
Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed some header addition to Toolkit distribution in
lib/silcutil/Makefile.am and lib/trq/Makefile.am.
* Added lib/silcclient/client_ops_example.h as an template
file for application programmers to quickly start using
the SilcClientOperation functions in their application.
Updated the lib/silcclient/README as well to tell about this
nice file made available.
Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Call silc_server_remove_from_channels when removing client
entry when NO_SUCH_CLIENT_ID was received. Affected file
is silcd/command_reply.c.
Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Added server & router operator statistics updating. Affected
file silcd/packet_receive.c and silcd/command.c.
* Fixed the SERVER_SIGNOFF notify handling on normal server
not to save the history information for clients. Same was
fixed earlier in remove_clients_by_server function, but not
here. Affected file silcd/packet_receive.c.
* Raised the default connection-retry count from 4 to 7 in
server. Affected file silcd/server.h.
* Cancel any possible reconnect timeouts when we start the
key exchange. Affected file silcd/server.c.
* Do not reconnect on connection failure when SCONNECT was
given. Affected files silcd/server.[ch].
Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Removed assert()'s from the lib/silcclient/client_keyagr.c.
* Fixed the NICK command to always give the unformatted
nickname to the one giving the NICK command. If unformatted
nickname is cached already it will be formatted and the
local entry will always get the unformatted nickname.
Affected file lib/silcclient/idlist.c.
* Fixed some double frees from client library commands.
Affected file is lib/silcclient/command.c.
* Fixed CUMODE command in server to assure that no one can
change founder's mode than the founder itself, there was a
little bug. Affected file silcd/command.c.
Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Removed the SilcClientCommandDestructor from the client
libary, it is not needed anymore. Affected files are
lib/silcclient/silcapi.h, command[_reply].[ch],
client_notify, idlist.c.
* Fixed GETKEY command to first resolve client, and then
resolve the server only if the client was not found, instead
of resolving both at the same time. Affected file is
lib/silcclient/command.c.
* Added silc_client_start_key_exchange_cb and lookup the
remote hostname and IP address before starting the key
exchange with server. The affected file is
lib/silcclient/client.c.
* The server's public key is now saved using the IP address
of the server and not the servername for the filename.
The hostname public key filename is checked as an fall back
method if the IP address based filename is not found.
Fixed the GETKEY command to save the fetched server key
in correct filename.
Print the remote server's hostname now when new key is
received during connection process. Affected file is
irssi/src/silc/core/client_ops.c.
* Return always our own public key to the client if it asks
for it with GETKEY command. Affected file silcd/command.c.
* Removed the use_auto_addr variable from default config
file since it was in wrong section. Affected file is
irssi/src/config.
* Fixed TOPIC_CHANGE notification to not route it when it
was sent using silc_server_send_notify_to_channel function.
Affected file silcd/command.c.
* Fixed silc_server_send_notify_kicked to send the kicker's
Client ID also, it was missing. Affected files are
silcd/command.c, silcd/packet_send.[ch].
Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Do not save client history information in SERVER_SIGNOFF.
Fixes the bug in normal server that it does not detect
the client becoming valid after the server becomes back
online. Affected file silcd/server_util.c.
* Added `sock_error' field into the SilcSocketConnection
context. When error occurs during socket operation (read
or write) the error is saved. Added also new function
silc_socket_get_error to return human readable socket error
message. Affected files are lib/silcutil/silcsockconn.[ch],
lib/silcutil/unix/silcunixsockconn.c, and
lib/silcutil/win32/silcwin32sockconn.c.
* The server now prints the socket error message in the
signoff for client. Affected file silcd/server.c.
* Fixed the `created' channel information sending from router
to server in JOIN command. Checks now whether the channel
really was created or not and set it according that.
Fixed the JOIN command to use the client entry's current
ID during the joining procedure instead of the one it sent
in the command (it is checked though), since it can change
between the packet processing and command processing, and
would just case unnecessary pain in the client end. Affected
file silcd/command.c.
* Fixed a channel key payload sending to use correct channel
ID when the server was forced to change the channel's ID by
router. Router sent the key payload with the old Channel ID.
Affected file silcd/packet_receive.c.
Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Call silc_server_save_channel_key only if the key payload
was provided in the JOIN command's command reply. Affected
file silcd/command_reply.c.
Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed silc_mp_sizeinbase to return the value correctly with
MPI. Affected file lib/silcmath/mp_mpi.c.
* Fixed the stop_server signal to correctly stop the scheduler
and gracefully stop the server when SIGTERM or SIGINT signals
are received. Affected file silcd/silcd.c.
Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
* Simple handling of TERM and HUP signals. Also added some log
flushing call around. Affected file is
silcd/silcd.c.
* Fixed small bugs in silclog.c. Now buffering output will take
effect after 10 seconds since startup: This will ensure that
no important startup messages are lost. Also output redirection
will preserve original format ([Date] [Type] message).
Affected file is lib/silcutil/silclog.c.
* Added two options to the config file, in the logging section:
quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Do not print the warning about log files not being initialized
more than once to avoid excess logging. Affected file is
lib/silcutil/silclog.c.
* Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
the SIM copying in make install in Makefile.am.pre.
Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
* Rewritten silclog APIs. Globally interesting changes follows:
silc_log_set_files() changed to silc_log_set_file().
silc_log_set_callbacks() changed to silc_log_set_callback().
ROBOdoc documented silclog header file.
SilcLogCb now returns bool to wether inihibit the default
handler or not (to keep the old behaviour return always TRUE).
The new APIs should also fix the problem of the
silcd_error.log file that was written in the current directory.
New features:
Log files streams will remain opened after silc_log_set_file()
call, means less CPU usage notably on high traffic servers.
File streams are now full buffered, and flushed to the disk
every 5 minutes, lesses HD activity and CPU usage.
Messages can be redirected, allowing admins to configure
one single logfile for all server messages.
the silc_log_quick global variable to activate fast-logging.
Affected files lib/silcutil/silclog.[ch]
* Changed some code to conform new silclog APIs. Affected
files are doc/example_silcd.conf.in, silcd/server.c
irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
silcd/silcd.c.
* Fixed a memory leak that could occur in some situations.
Affected file silcd/serverconfig.c.
Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Added the silc_client_del_client to remove the client from
all channels as well. Affected file lib/silcclient/idlist.c.
* Fixed the client library to correctly remove the client
from all channels when the client entry is being destroyed.
Affected file lib/silcclient/client_notify.c, command.c.
* Added auto-nicking support to the client library. If the
applicatio now sets client->nickname it will be sent to the
server after connecting by the library. This way for example
SILCNICK (or IRCNICK) environment variables will have effect
and always change the nickname automatically to whatever
it is wanted. Affected file lib/silcclient/client.[ch].
* Renamed silc_server_command_bad_chars to the
silc_server_name_bad_chars and moved it to the
silcd/server_util.[ch]. Added also new function
silc_server_name_modify_bad to return nickname that
includes bad characters as new nickname without those
bad characters. This check and modify is now used in
silc_server_new_client when the username is initially set
as nickname, so it must be checked to be valid nickname.
Affected file silcd/packet_receive.c.
* The nickname length is now taken from the packet for real
and not trusted to strlen() since it clearly can return
wrong length for nickname including bad characters. This
also applies to channel names. Affected file silcd/command.c.
* Removed the lib/silcsilm/modules directory. Modules are now
compiled into the lib/silcsim. Fixed the copying of the
modules to follow symbolic links in Makefile.am.pre.
Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
* Fixed silc_string_regexify list creation. Fixes bugs with
BAN and INVITE commands in server. The affected file is
lib/silcutil/unix/silcunixutil.c.
Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Removed the command destructor entirely from the server's
command and command reply routines. It is not needed, and
its usage was buggy and caused crashes. Affected files are
silcd/command[_reply].[ch].
Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Cancel protocol and NULL sock->protocol if timeout
occurred during protocol. Affected file silcd/server.c.
* Cancel protocol timeouts always before calling the final
callback, to assure that after final callback is called
no other state will be called for the protocol anymore.
Affected file silcd/protocol.c.
* Print error log if incoming connection configuration could
not be found. Affected file silcd/server.c.
* Fixed JOIN command to correctly save the founder mode
to the client on normal SILC server, when the channel
was created by the router. Affected file silcd/command.c.
* Fixed LIST command (hopefully) to send correct reply
packets. Affected file silcd/command.c.
Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
* The silc_packet_receive_process now returns FALSE if the
read data was invalid packet, and TRUE if it was ok.
The server now checks that if unauthenticated connection
sends data and its processing fails the server will close
the connection since it could be a malicious flooder.
Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Make sure the warning about error opening a log file is
printed only once and not everytime it fails (produces
too much useless log). Affected file lib/silcutil/silclog.c.
Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
* Made the silc_server_daemonise() function more readable.
Affected file silcd/server.c.
* Pid file is now optional, the user may comment it out from
the config file. Removed define SILC_SERVER_PID_FILE, we
don't need a default any longer. Affected file
configure.in.pre, lib/Makefile.am.pre.
* Make some use of the pid file. The server now dies at startup
if it detects a valid pid file on his path. The server would
die anyway in this circumstance, because of the bind() failure.
Affected file silcd/silcd.c.
* No longer compiling lib/dotconf.
Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed JOIN command parsing not to crash. Affected file
lib/silcclient/command.c.
* Fied the NICK_CHANGE notify to add the new client entry
even it is resolved. This removes an <[unknown]> nick
thingy bug in the client. Affected file is
lib/silcclient/client_notify.c.
* Do not try to allocate 0 bytes (efence does not like it)
in lib/silccore/silccomand.c when encoding payload.
* Do not take IRCNICK as nickname in Irssi SILC client since
it is not possible to set nickname before hand connecting
the server (TODO has an entry about adding auto-nicking
support).
* Changed the silc_server_command_pending to check whether
there already exists an pending entry with the specified
command, command identifier and pending callback. This is
to fix IDENTIFY and WHOIS related crashes that may register
multiple pending commands with same identifier. Affected
file silcd/command.c.
* Fixed the server to reconnect to the router even if it
was already reconnecting and EOF was received. This to
fix a possibility that the server wouldn't ever try to
auto-reconnect to the router. Affected file silcd/server.c.
Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed the server's password authentication to use the
length of the locally saved password, and not the one
sent in the packet. Affected file silcd/protocol.c.
* Fixed same password authentication problem in the
Authentication Payload handling routines in
lib/silccore/silcauth.c.
* Yet another password authentication problem fixed with
channel password handling in silcd/command.c.
Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* If first character of string in silc_parse_userfqdn is '@'
then do not parse it. Affected file is
lib/silcutil/silcutil.c.
Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed minor bug in IDENTIFY command reply sending, which
caused various weird problems during JOIN when it was
resolving names for users. Affected file silcd/command.c.
Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed the IDENTIFY command reply sending to chech better valid
clients. It was possible to send incomplete list of replies.
Affected file silcd/command.c.
Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Added silc_client_command[s]_[un]register functions now to
dynamically register the commands in client library. Removed
the static table of commands. This allows the client library
to call commands without causing the application to know about
what commands library has called.
Removed the INFO command reply kludge to detect when the command
was called by library. Now library use its own command reply
function for INFO command.
Added function silc_client_command_call to call a command.
Application can use it to call command, not access the structure
directly.
Now all commands that are sent by the client library (not
explicitly sent by application) use own command reply functions.
Affected files around lib/silcclient/ and in
irssi/src/silc/core/.
* Fixed the WHOIS command reply sending to chech better valid
clients. It was possible to send incomplete list of replies.
Fixed the WHOIS and IDENTIFY to send the request to router
if normal server did not do it and did not find any results.
Affected file silcd/command.c.
Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Moved the internal data from SilcClient context into its
own file, not accesible to application. Affected files
lib/silcclient/client.h and lib/silcclient/client_internal.h,
and other files in client library.
Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Added doc/examples installation target in Makefile.am.pre.
A patch by salo.
Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
commands the found client entry will be removed from the
cache, after notifying application about the error. Affected
file lib/silcclient/command_reply.c.
* Changed the /MSG to check for exact nickname user gave, and
not let `nick' match `nick@host' if it is only one found. Now,
user must type the exact nickname (like nick@host2) even if
there are no more than one same nicks found. This is to avoid
a possibility of sending nickname to wrong nickname since
`nick' could match `nick@host'. Affected file is
irssi/src/core/silc-servers.c.
Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Do not print "you are now server operator" or similar when
giving /away command. Affected files are
irssi/src/silc/core/client_ops.c, silc-servers.h.
* Made the silc_server_command_pending_error_check to send
the same command reply payload it received back to the
original sender of the command. This way all arguments
that was received by the server will be received by the
client too. Affected file silcd/command.c.
* Added the silc_idcache_add to return the created cache entry
to a pointer. Affected file lib/silccore/silcidcache.[ch].
* Add global clients to expire if they are not on any channel.
This is because normal server will never know if they signoff
if they are not on any channel. The cache expiry will take
case of these entries. This is done by normal servers only.
The affected files are silcd/command_reply.c,
silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
* If server receives invalid ID notification for WHOIS or
IDENTIFY and the ID exists in the lists, it is removed.
Affected file silcd/command_reply.c.
* If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
in client then client entry that it matches is searched and
the nickname is printed on the screen for user. Affected
file irssi/src/silc/core/client_ops.c.
Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Use cache entry expire time in the LIST command reply to
purge old entries from the cache after the LIST command
reply has been received. This way we don't have non-existent
entries in the cache for too long. Affected file is
silcd/command_reply.c.
Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* If we are normal server, and we've not resolved client info
in WHOIS or IDENTIFY from router, and it is global client,
we'll check whether it is on some channel. If it is not
then we cannot be sure about its validity and will resolve it
from router. Fixes a bug in WHOIS and IDENTIFY. Affected
file silcd/command.c.
* Search channel by name (if possible) rather than by ID
in IDENTIFY command's command reply. Affected file is
silcd/command_reply.c.
Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Distribute to the channel passphrase in CMODE_CHANGE notify.
Updated specs and implemented it. Affected file silcd/command.c,
silcd/packet_send.c and silcd/packet_receive.c.
* Implemented the <founder auth> payload handling in the JOIN
command. If provided all conditions for channel joining
except requirement to provide correct passphrase can be
overrided by the channel founder. Updated the protocol specs.
Affected file silcd/command.c.
Added support for founder auth in JOIN command in client
library. Fixed the parsing of the JOIN command now to support
all options as they should be. The affected file is
lib/silcclient/command.c.
* Optimized the WHOIS and IDENTIFY commands to send the request
to router only if it includes nicknames or other names. If
they include only IDs then check the local cache first before
routing. Affected file is silcd/command.c.
* Added channels topic announcements. Affected file is
silcd/packet_receive.c and silcd/server.c.
* Fixed the silc_server_send_notify_topic_set to really destine
the packet to channel. Affected file silcd/packet_send.c.
* Fixed a crash in CHANNEL_CHANGE notify handling in the client
library. Affected file lib/silcclient/client_notify.c.
* Added UMODE announcements. Affected file silcd/server.c.
Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Memory leak fixes in:
lib/silcutil/silcsockconn.c
lib/silcske/silcske.c
lib/silcske/groups.c
lib/silccrypt/rsa.c
lib/silccrypt/silcpkcs.c
lib/silccore/silccommand.c
lib/silccore/silcidcache.c
silcd/idlist.c
silcd/packet_send.c
silcd/command.c
* ROBOdoc documented the lib/silcske/groups.h file and a
bit changed the interface for better.
Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
* Update the client entry context in the ID cache after
nick change. Affected file lib/silcclient/command.c.
Fixes the CUMODE command when regaining founder privileges,
and a little WHOIS problem.
* Fixed silc_net_gethostbyname to correctly call the
inet_ntop. Affected file lib/silcutil/silcnet.c.
Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
* Added IPv6 support checking to the configure.in.pre, added
also --enable-ipv6 option to override the check. Affected
file configure.in.pre.
* The silc_thread_create now calls the start function
directly if threads support is not compiled in. Removes
ugly #ifdef's from generic code. Affected files are
lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
* Added silc_net_gethostby[name/addr]_async to asynchronously
resolve. Affected files are lib/silcutil/silcnet.[ch].
* Added support for rendering IPv6 based server, client and
channel IDs. Affected file lib/silcutil/silcutil.c.
* Added support for creating IPv6 based server IDs. Affected
file is silcd/serverid.c.
Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
* Added silc_net_gethostby[addr/name] into the
lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
routines. Added silc_net_is_ip[4/6]. Affected file is
lib/silcutil/unix/silcunixnet.c. All routines that take
address as argument now supports both IPv4 and IPv6 addresses.
Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
* Fixed LIST command reply sending in server. Affected file
silcd/command.c.
* Server now sends the kicker's client ID in the KICK notify
to the kicked client. Affected file silcd/command.c.
* The client library now parses the kickers client ID and
UI displays it. Affected files lib/silcclient/client_notify.c
and irssi/src/silc/core/silc-channels.c, module-formats.c.
* Made all payload parsing function prototypes consistent.
They all take now const unsigned char * and uint32 pair as
the payload data instead of SilcBuffer. Changes all around
the source tree. Other unsigned char* -> const unsigned char*
changes around the tree as well.
* Optimized SFTP client and server packet sending not to
allocate new buffer for each packet but to recycle the
first allocated buffer. Affected files are
lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
* Optimized the SFTP client to use SilcList instead of
SilcDList for requests, because it is faster. Affected file
is lib/silcsftp/sftp_client.c.
* Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
into lib/silccore/silcid.[ch].
Renamed silcpayload.[ch] into silcargument.[ch].
Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
* If client entry is deleted with active key agreement
session, abort the session.
The silc_client_abort_key_agreement now calls the completion
callback with new SILC_KEY_AGREEMENT_ABORTED status.
Affected file lib/silcclient/silcapi.h, client_keyagr.c and
idlist.c.
Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Don't use __restrict in older GCC's. Affected file is
lib/silcmath/mpi/mpi-priv.h. A patch by salo.
* silc_net_localhost now attempts to reverse lookup the
IP/hostname. Affected file lib/silcutil/silcnet.c.
* Defined <founder auth> argument to the SILC_COMMAND_JOIN
command. It can be used to gain founder privileges at
the same time when joining the channel.
Defined that the SILC_NOTIFY_TYPE_KICKED send the
kicker's client ID as well. Updated protocol specs.
Defined that the server must send SILC_COMMAND_IDENTIFY
command reply with error status to client who sent
private message with invalid client ID.
Updated the protocol specification.
* Added silc_server_send_command_reply to send any
command reply. Affected file silcd/packet_send.[ch].
* Added silc_id_payload_encode_data to encode ID payload
from raw ID data. Affected file lib/silccore/silcpayload.[ch].
* The server now send IDENTIFY command reply with error
status if client ID in private message is invalid. Affected
file silcd/packet_receive.c.
* Save the server key file with server's IP address in
the filename instead of hostname. The affected file is
irssi/src/silc/core/client_ops.c.
Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Typo fixes in irssi/src/fe-common/silc/module-formats.c.
A patch by Sunfall.
* Added libtool support for compiling shared objects in
lib/silcsim. Affected file configure.in.pre and
lib/silcsim/Makefile.am. Original patch by cras.
Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Pid file configuration, and server's config file fixes
patch by toma. Updated CREDITS file.
Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed silc_client_channel_message to not try to decrypt
the message twice if it resolved the destination client
information. This could cause of dropping one channel
message. Affected file lib/silcclient/client_channel.c.
Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Added silc_client_run_one into lib/silcclient/silcapi.h and
lib/silcclient/client.c. This function is used when the SILC
Client is run under some other scheduler, or event loop or
main loop. On GUI applications, for example this may be
desired to used to run the client under the GUI application's
main loop. Typically the GUI application would register an
idle task that calls this function multiple times in a second
to quickly process the SILC specific data.
Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
* Fixed silc_server_drop() for dropping the supplementary
groups as well, this could cause a security hole on some
systems.
Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
johnny.
* Write PID file after dropping privileges. Added -F option
to run server on foreground. A patch by debolaz.
Affected files silcd/server.c, silcd/silcd.c.
* Fixed MOTD to return the MOTD file server name. Affected
file silcd/command.c.
* Added INFO command reply handling to the Irssi SILC Client.
Affected file irssi/src/silc/core/client_ops.c.
Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed the silc_idcache_list_* routines to really support
the dynamic list. Fixes a crash. Affected file is
lib/silccore/silcidcache.c.
* Fixed the LIST command reply to really call LIST command's
pending callbacks. Affected file silcd/command_reply.c.
Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Update conn->local_entry->nickname after giving NICK
command. Affected file lib/silcclient/command.c.
Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
* Added the [pid] option to the silcd configuration file
Affected files: serverconfig.[ch] and silcd.c
Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Save fingerprint in WHOIS command reply in server.
Affected file silcd/command_reply.c.
* Fixed NICK commands pending callback registration.
Affected file lib/silcclient/command.c.
Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Use ++server->cmd_ident when sending commands in server,
instead of random number. Affected file silcd/command.c.
* Fixed GETKEY command reply to call actually GETKEY pending
command callbacks. Affected file silcd/command_reply.c.
* A bit stricter check for nicknames. Check for same nickname
in NICK command also. Affected file silcd/command.c.
* Do not call INFO command everytime client ID changes, only
during first connecting. Affected file lib/silcclient/client.c.
* Set the new nickname only after successful command reply for
NICK command is returned by server. Affected file
lib/silcclient/command.c.
* Remove nicknames from nicklist during server_signoff notify.
Should fix /NAMES bit more. The affected file is
irssi/src/silc/core/silc-channels.c.
* Added `fingerprint' field to the SilcIDListData in the
silcd/idlist.h to hold the fingerprint of the client's
public key.
Send the fingerprint of the client's public key in WHOIS
command reply.
Affected files silcd/command.c, and silcd/idlist.[ch].
* Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
create fingerprint from given data.
* Show the fingerprint of the client's public key in WHOIS.
Affected files irssi/src/module-formats.[ch] and
irssi/src/silc/core/client_ops.c.
* Format the multiple same nicknames also during JOIN and
NICK_CHANGE notifys. Affected file is
lib/silcclient/client_notify.c.
* Do not print error on screen for invalid private message
payload since it can come if someone is sending private
messages with wrong key. Affected file
lib/silccore/silcprivate.c.
* Fixed multiple concurrent /PING crash. Affected file
lib/silcclient/command.c.
* Changed the wrong ID encoding. All IP addresses must be
in MSB first order in encoded format. They were encoded
wrong and was in LSB format. Affected files are
silcd/serverid.c, lib/silcutil/silcutil.c.
* Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
* Call the `connect' client operation through the scheduler
in case of error. Affected file lib/silcclient/client.c.
* Call the `failure' client operation even if the error
occurred locally during a protocol. Affected file is
lib/silcclient/protocol.c.
* Added support of sending LIST command to router from normal
server. This way normal server can get list of all channels
in the network too. Fixed the channel list sending in the
server too. Affected files are silcd/command.c, and
silcd/command_reply.[ch].
* Added silc_server_update_channels_by_server and
silc_server_remove_channels_by_server. They are used during
disconnection of primary router and in backup router protocol.
Affected file silcd/server_util.[ch], silcd/server.c and
silcd/server_backup.c.
* Fixed channel adding to global list in IDENTIFY command
reply in server. Affected file silcd/command_reply.c.
Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* If the incoming packet type is REKEY or REKEY_DONE process
that packet always synchronously. Fixes yet another MAC
failed error on slow (dialup) connections. Affected file
lib/silcclient/client.c and silcd/server.c.
Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Call check_version SKE callback for initiator too. Affected
file lib/silcske/silcske.c.
* Implemented fix for security hole found in the SKE that was
fixed in the specification few days back; the initiator's
public key is now added to the HASH value computation.
Added backwards support for the old way of doing it too, for
old clients and old servers. Affected file is
lib/silcske/silcske.c.
* Enabled mutual authentication by default in SKE. If initiator
is not providing mutual authentication the responder will
force it. This will provide the proof of posession of the
private key for responder. The affected files are
lib/silcclient/protocol.c and silcd/protocol.c.
* Do not cache anymore the server's public key during SKE.
We do mutual authentication so the proof of posession of
private key is done, and if the server is authenticated in
conn auth protocol with public key we must have the public
key already. Affected file silcd/protocol.c.
* Added new global debug variable: silc_debug_hexdump. If
it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
file lib/silcutil/silclog.[ch].
* Fixed compilation warning due to char * -> const char *.
Affected files lib/silcutil/silcnet.h, and
lib/silccore/silcauth.[ch].
Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed CMODE command when new channel key was created. If
the creation failed the old key was removed. Next time giving
same command would crash the server since the old key was
freed already. Affected file silcd/command.c.
* Fixed the silc_server_announce_get_channels to not crash
on reconnect. Affected file silcd/server.c.
Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Added silc_log_set_debug_string function to set a regex
string to match for debug output. Only the function names,
or filenames matching the given debug string is actually
printed. This way it is possible to filter out those debug
strings that user is not interested in.
Fixed a bug in silc_string_regexify.
Affected files lib/silcutil/silclog.[ch], and
lib/silcutil/unix/silcunixutil.c.
* Changed the -d options in both server and Irssi SILC client
to take the debug string as argument. Affected files
silcd/silcd.c and irssi/src/silc/core/silc-core.c.
Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Added silc_hash_babbleprint to create a Bubble Babble
Encoded fingerprint. The encoding is developed by Antti
Huima (draft-huima-babble-01.txt), and it creates human
readable strings out of binary data. Affected file
lib/silccrypt/silchash.[ch].
* Print the babble print now in addition of fingerprint as well
in Irssi SILC client. Affected files are
irssi/src/fe-common/silc/module-formats.[ch],
irssi/src/fe-common/silc/core/client_ops.c.
Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed a security problem found in SKE. The initiator's
public key too is now added to the HASH hash value creation
which is signed by the responder to create the SIGN value.
This will prevent anyone in the middle to lie to the responder
about the initiator's public key. If this is done now, the
man in the middle will get caught. Updated the protocol
specification.
Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Better installation directory handling. Configure module
paths and other paths automatically to example_silc* files
in doc/. A patch by toma.
* Fixed compiler warning from MPI library, and from SILC RNG.
A patch by johnny.
* Added SILC_SERVER_PID_FILE to define the pid file for server.
It can be configured with ./configure. A patch by toma.
Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Find correct make to use in prepare-clean. A patch by
toma. Affected file prepare-clean.
Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
* Added irssi variables use_auto_addr, auto_bind_ip,
auto_bind_port and auto_public_ip.
* Changed the interface for silc_client_send_key_agreement
in lib/silcclient/silcapi.h
Affected files:
irssi/src/silc/core/silc-core.c
irssi/config
lib/silcclient/silcapi.h
irssi/src/silc/core/silc-channels.c
lib/silcclient/client_keyagr.c
irssi/docs/help/key
Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
* Added silc_pkcs_public_key_compare to compare two
public keys. Affected file lib/silccrypt/silcpkcs.[ch].
* Check that the client who set the founder mode on the
channel is the same client that is giving the founder
mode to itself. It is done by comparing the saved public
key (it is saved even in the authentication is passphrase).
Affected file silcd/command.c.
Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
* Do not process packet for disconnected socket connection.
Affected file lib/silccore/silcpacket.c.
* Process the DISCONNECT packet through scheduler in the
client library. Affected file lib/silcclient/client.c.
* Fixed the silc_client_packet_parse to not to increase
the packet sequence number if the conn->sock and the
current socket connection is not same. This can happen
for example during key agreement when the conn includes
multiple socket connections (listeners). Affected file
lib/silcclient/client.c.
* The sender of the file transfer request now provides also
the pointer (listener) for the key exchange protocol. If
the listener cannot be created then it sends empty key
agreement and lets the receiver provide the listener.
Added `local_ip' and `local_port' arguments to the
silc_client_file_send. If they are provided they are used,
if not then it will attempt to find local IP address, if
not found or bind fails then the remote client will provide
the listener.
Affected files are lib/silcclient/client_ftp.c and
lib/silcclient/silcapi.h.
* Extended the FILE SEND command to support defining the
local IP and port for key exchange listener. They are
optional. Affected file irssi/src/silc/core/silc-servers.c.
Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
* Defined to WHOIS command reply the sending of fingerprint
of the client's public key (if the proof of posession of the
corresponding private key is verified by the server).
Updated to the protocol specification.
* Added support of receiving the client's public key's
fingerprint in command reply in client library. Affected

the library. The Irssi SILC client will use now client
retrieval functions found in silcapi.h.
* Fixed a bug in resolving nickname info before sending
private message. It used freed memory. Affected file
irssi/src/silc/core/silc-servers.c.

The SILC packet header change makes it impossible to be
backwards compatible.
* Send the ENDING packet with timeout in the backup resuming
protocol. This is to assure that all routers has connected
to the primary router. Affected file silcd/server_backup.c.
* Changed the RNG to take the first IV from random data. It
used to take it from zero actually. Changed the RNG also
to use /dev/urandom during session. /dev/random is used
in initialization. Affected file lib/silccrypt/silcrng.[ch].
Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
* Changed the SILC packet header to have the first two bytes
(the packet length) encrypted. Affected files aroung the
code tree, lib/silccore/silcpacket.[ch]. Removed the
SilcPacketCheckDecrypt callback. It is not needed anymore
since the silc_packet_receive_process will determine now
whether the packet is normal or special.
* Implemented the unidirectional MAC keys. Affected files
lib/silcske/silcske.c, silcd/protocol.c and
lib/silcclient/protocol.c.
* Implemented the packet sequence number to the MAC computation.
Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
lib/silcclient/protocol.c.
Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
* Allow backup router to announce servers. All servers
announced by backup router are added to the global list
automatically. Update hte server's socket to our primary
router also when backup router announces a server.
Affected file silcd/packet_receive.c.
* Do not update the client->router in the function
silc_server_udpate_clients_by_server if the client is on
global list. We might fail to find any specific server
for locally connected clients and local cell clients. They
should still use the `from' and not `to' as client->router.
This fixes backup router resuming protocol. Affected file
silcd/server_util.c.
* Decrease channel statistics count only if the channel
deletion worked. Affected files are silcd/server.c and
silcd/server_util.c.
* Added silc_server_update_servers_by_server to update origin
of all server entries. Used during backup router protocol.

Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
* Assure that router cannot reroute the same channel message
to the sender. Affected file silcd/packet_receive.c.
Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
* Made better checks that the channel message is not sent
to the router it came from. Affected file is
silcd/packet_send.c. Fixed memory leak too.
* Announce informations for incoming router connection, but
only after checking if it is replaced by backup router.
Affected file silcd/packet_receive.c.
Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
Affected file silcd/packet_send.c.
* Changed the SFTP Filesystem interface. Changed the
SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
the filesystem operation function. The SilcSFTPFilesystem
is now a context that is allocated by all filesystem allocation
functions and it already includes the operations structure
and filesystem specific context. It is given as argument
now to the silc_sftp_server_start. This made the interface
a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,

Affected file lib/silcclient/command.c.
* Assure that if outgoing data buffer is pending do not force
send any data. Affected file silcd/packet_send.c.
* Assure that if outgoing data buffer is pending do not force
send any data. Affected file lib/silcclient/client.c.
* Implemented the backup router support when the primary router
goes down. The servers and routers can now use the backup
router as new primary router without loosing connectivity.
Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
* Added new SILC_IDLIST_STATUS_DISABLED flag for entries
in the server to indicate disabled entry. All data read
from the connection will be ignored and no data is sent
for entry that is disabled. Affected files are
silcd/idlist.h, silcd/server.c.
Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
* Created SFTP client and server test programs in the
lib/silcsftp/tests directory.
Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

sftp_fs_memory.c.
Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Implemented the SFTP (SSH File Transfer Protocol) to the
lib/silcsftp. It includes SFTP client and SFTP server
implementations.
Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Moved lib/silccore/silcprotocol.[ch] to the
lib/silcutil library.
* Added silc_buffer_format_vp and silc_buffer_unformat_vp to
take variable argument list pointer as argument. Affected
file lib/silcutil/silcbuffmt.[ch].
* Added silc_buffer_set function that is used to set data
to a SilcBuffer that is not allocated at all (SilcBufferStruct).
Affected file lib/silcutil/silcbuffer.h.
* Changed various routines in the core library to use the new
silc_buffer_set instead of allocating new buffer only for
temporary purposes.
* Added 64-bit value formatting and unformatting support to the
silc_buffer_[un]format routines. Affected file is
lib/silcutil/silcbuffmt.[ch].
Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
to includes/bitmove.h.
Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

file lib/silcclient/command[_reply].c.
Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Defined the file transfer to the SILC Protocol. Added
new packet type SILC_PACKET_FTP and defined File Transfer
Payload. The mandatory file transfer protocol is SFTP
(SSH File Transfer Protocol). Affected file in addition
of the internet draft is lib/silccore/silcpacket.h.
* Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
packet SILC_PACKET_RESUME_ROUTER instead. The new packet
is used as part of backup router protocol when the primary
router of the cell is back online and wishes to resume
the position as primary router.
* Redefined the MAC generation keys in the protocol. The
same key is not used anymore in both direction. Both
direction will now use different keys for sending and
receiving. This fixes a potential security flaw. This
change causes incompatibilities in the protocol.
* Redefined also the MAC computation from the packet.
An packet sequence number is now added to the MAC
computation. This prevents possible replay attacks against
the protocol. This change too causes incompatibilities
in the protocol.
Added `sequence' field to the SilcPacketContext to hold
the current sequence number for the packet.
Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

silcd/idlist.h to indicate the time when the entry was
created.
* Added `created' field to the SilcChannelEntry too. Affected
file silcd/idlist.h.
* Added `creation_time' aguments to all the announcement functions
in the server. If it is provided then only the entries that
was created after the provided time frame are actually
announced. Affected file silcd/server.[ch].
* The protocol says that the Channel ID's IP address must be
based on the router's IP address. Added check for this in
the silc_server_new_channel when processing incoming New Channel
Payload. Affected file silcd/packet_receive.c.
* Print out the correct version with --version in SILC client.
Affected file irssi/src/silc/core/silc-core.c.
Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed WHOWAS command to check for completnes of the client
entry always, not just when the command is coming from client.
Affected file silcd/command.c.
* Added new function silc_server_packet_queue_purge to purge the
outgoing data queue to the network. After the function returns
it is guaranteed that the outgoing packet queue is empty.
Affected file silcd/packet_send.[ch].
* Purge the outgoing packet queue in the rekey protocol's final
callback to assure that all rekey packets go to the network
before quitting the protocol. Affected file silcd/server.c.
* Added silc_client_packet_queue_parse as similar function as
in server to the client library. The affected file is
lib/silcclient/client.c.

* Splitted silcd/server.c and created silcd/server_util.[ch]
for utility functions.
* Added new socket flag SILC_SF_DISABLED to indicate that the
connection is open but nothing can be sent to or received from
the connection. Affected file lib/silcutil/silsockconn.[ch].
The checking for disabled socket is checked in the low level
silc_socket_write and silc_socket_read functions.
Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Allow only nicknames and channel names that fits into the
7-bit unsigned char ASCII set. Affected file silcd/command.c.
Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* When processing JOIN command reply in server check that if
the channel exists in our global list we'll move it the local
list. Affected file silcd/command_reply.c.
* Fixed the check whether client is joined on the channel already
in JOIN command. Affected file lib/silcclient/command.c.
* Fixed the JOIN command reply to check whether the channel
already exists. Affected file lib/silcclient/command_reply.c.
Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

silcd/server.c.
Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Assure that the packet length digged from the actual packet
is something sensible in the silc_packet_decrypt_rest_special
in lib/silccrypt/silcpacket.c.
* Free and NULL the allocated pointer in silc_hmac_alloc if
the HMAC allocation fails. The affected file is
lib/silccrypt/silchmac.c.
* Print the selected security properties to the log files in
the server. Affected file silcd/protocol.c.
* Add SKE's reference counter even if calling the completion
callback manually. Otherwise it goes negative, although it
does not cause any problems. The affected file is
lib/silcske/silcske.c.
* Remove the client entry with short timeout after giving the
KILL command. Affected file lib/silcclient/command.c.
* Fixed to send error reply in WHOIS and IDENTIFY commands in
case all found clients are already disconnected (WHOWAS would
found them) in the server. Affected file silcd/command.c.
* Update the last_receive (time of last data received) to be
updated only when received private or channel message so that
the idle time showed in WHOIS makes more sense.
* Added boolean field `valid' in to the SilcClientEntry in the
client library to indicate whether the entry is valid or not.
This fixes the nickname change bug on channel when changing
the nickname to be same than the old (like nick to Nick) the
nickname formatter doesn't set the new nick anymore to Nick@host.
Affected file lib/silcclient/idlist.[ch].
* Now actually fixed the nickname changing on disconnection.
Added new function silc_change_nick to the Irssi SILC Client.
Affected file irssi/src/silc/core/client_ops.c,

GETKEY command instead of INFO command. Affected file
lib/silcclient/command.c.
* All command reply functions in the client library now calls
the pending command reply callbacks even if an error has
occurred. The server has done this a long time and now it was
time to move the client library to this as well. Now all
errors can be delivered back to the pending command reply
callbacks if necessary. Affected files are
lib/silcclient/command[_reply].[ch].
* Change the nickname on disconnection back to the username
because in reconnect the server will enforce it to it anyway.
Affected file irssi/src/silc/core/silc-servers.c.
* Fixed a config file parsing bug in the Irssi SILC client.
Affected file irssi/src/silc/core/clientconfig.c.
Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* When printing the channel mode on JOIN, verify that the
channel key and channel's HMAC are valid. Affected file

* Removed channel key rekey task deleting from the function
silc_server_save_channel_key. Affected file silcd/server.c.
Added explicit timeout task context instead that is used to
delete the task if we are registering a new task before the
new task has elapsed.
* When channel key rekey occurs the client library now saves
the old channel key for a short period of time (10 seconds) and
is able to use it in case some is still sending channel
messages encrypted with the old key after the rekey. Affected
file lib/silcclient/[idlist.h|client_channel.c].
Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Added check to the silc_server_new_id_real to not accept
new ID if it is the sender's own ID. Affected file is
silcd/packet_receive.c.
* Assure that we do not announce ourself or the one we've
sending our announcements when we're router and are announcing
servers to our primary router. Affected file silcd/server.c.
* Fixed silc_server_command_identify_check_client to assemble
correct WHOIS packet. It send corrupted WHOIS packet and
caused problem with router to router connections. Affected
file silcd/command.c.
Fixed also silc_server_command_whois_check the same way
as for the IDENTIFY command.
* Added new SilcIDListStatus to the server in the SilcIDListData
structure. The status now includes the current status of
the entry (like registered, resolved etc.). Affected file
silcd/idlist.[ch]. Defined a bunch of different status types
as well. This replaced the old boolean registered field as well.
Added resolve_cmd_ident field to the SilcClientEntry structure
too so that if the entry is for example being resolved so
another command may attach to the same pending command reply
without requiring to resolve the same entry again. This concept
should optimize the WHOIS and the IDENTIFY resolving under
heavy load by taking away unnecessary resolving for entries
that are being resolved already.
Added support for adding multiple pending commands for one
command idenfier. Affected file silcd/command[_reply].[ch].
* Fixed WHOIS and IDENTIFY save to remove the cache entry
before deleting the data. Otherwise the hash table will have
freed data in comparison functions. Affected file is
silcd/command_reply.c.
* Fixed silc_idlist_replace_client_id to add the new entry to
the cache with NULL nickname. Otherwise there will be invalid
memory as the nickname after the nickname is freed. Affected
file silcd/packet_receive.c.
* Fixed the silc_idlist_get_clients_by_hash. The entries was
saved into wrong slots because the previous number of entries
was not taken into account. Affected file silcd/idlist.c.
Fixed same thing in silc_idlist_get_clients_by_nickname too.
* If we are router and we receive JOIN notify to a channel that
does not have any users then notified client is marked as the
channel founder, as it is it. The affected file is
silcd/packet_receive.c
* Added to the extended hash table API's table_del_*ext functions
the destructor as argument too, so that the caller can decide
which destructor to use or whether to use destructor at all.
Affected file lib/silcutil/silchashtable.[ch].
* Fixed ID Cache purging. It actually deleted the entries from
the hash table after the data was freed. The hash table ended
up comparing freed memory. The affected file is
lib/silccore/silcidcache.c.
Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed Irssi SILC client's KILL command's HELP syntax.
* The USERS command now resolves the detailed user information
if the userinfo field is missing. Affected file is
lib/silcclient/command_reply.c.
* Do not print error in silc_file_read if the read file does
not exist. Just silently return NULL. Affected file is
lib/silcutil/silcutil.c.
* Fixed the silc_log_output to not wine about NULL filename
and to not create some bogus " " filename. Affected file is
lib/silcutil/silclog.c.
Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed various printing bugs on the user interface in the
Irssi SILC Client. Minor changes that were forgotten from
the release.
Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed the configure.in.pre and the compilation and distribution
environment to support the new autoconf 2.52. That version is
now required to compile the CVS trunk.
Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Renamed function silc_parse_nickname to silc_parse_userfqdn
to generally parse user@fqdn format strings. Affected file
lib/silcutil/silcutil.c.
* Added nickname_format and nickname_force_format fields to the
SilcClientParams structure. The first one defines the format
for the nicknames that the library will enforce if the receives
multiple same nicknames. The second one is boolean value and
can be used to force the library to always enforce the format
to the nicknames regardles whether there are multiple nicknames
or not. This configurable formatting was employed to flexibly
support accessing multiple nicknames from the user interface.
The userinterface can now set the nicknames to what ever format
they prefer. Affected file lib/silcclient/silcapi.h.
Added function silc_client_nickname_format to the file
lib/silcclient/idlist.c. It performs the nickname formatting.
Added new field `hostname´ to the SilcClientEntry context.
It holds the hostname of the client. Affected file is
lib/silcclient/idlist.h.
* Irssi SILC Client sets the nicknames in nick@hostn format.
Fe. priikone@otaku, priikone@otaku2 etc. Affected file
irssi/src/silc/core/silc-core.c.
The WHOIS printing now also shows both the real nickname and
the formatted nickname so that user knows how to access the
user if there are multiple same nicknames cached. Affected
file irssi/src/silc/core/client_ops.c. Changed the WHOIS
printing formatting too to take the hostname now as a separate
argument. The Affected file is
irssi/src/fe-common/silc/modules-formats.[ch].
* Changed the silc_client_get_clients_local to accept the formatted
nickname as argument. It accepts the real nickname too but the
formatted nickname can be used to find the true entry from
multiple entries. Affected file lib/silcclient/silcapi.h and
lib/silcclient/idlist.c.
* Added nickname_format_parse field to the SilcClientParams.
It is a callback function provided by the application to parse
the nickname out of the formatted nickname string. The library
calls it to get the nickname from the formatted string. Since
the application generally knows better the format of the nickname
string it parses it instead of the library, even though library
encodes the formatted string. If the callback function is not
provided then the library will use the string as is. The
affected file is lib/silcclient/silcapi.h.
* All the nickname strings passed to the client library in
commands are now expected to be formatted nickname strings.
If the command does not support the formatted nickname string
it will assume that the sent string is the actual nickname.
Affected file lib/silcclient/command.c.
Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Added public key authentication support to OPER and SILCOPER
commands in the client library. Affected file is
lib/silcclient/command.c.
Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Changed the get_auth_methdod client operation to be asynchronous.
It can be async if the application resolves the authentication
method from the server during the negotiation. Added new
SilcGetAuthMeth completion callback that the application will
call after resolving the authentication method.
Added function silc_client_request_authentication_method that
the application can use to resolve the authentication method
from the server. Added also SilcConnectionAuthRequest callback
that the library will call after the server has replied. The
application can call this function if it does not know the
current authentication method.
Affected files are lib/silcclient/client.c and
lib/silcclient/silcapi.h.
* The Irssi SILC client now automatically resolves the authentication
method incase any configuration information is not present (and
currently there never is). The affected file is
irssi/src/silc/core/client_ops.c.
* Fixed public key authentication from the client library.
Affected file lib/silcclient/protocol.c. Changed also the
protocol specification about the public key authentication in
the connection authentication protocol. The actual data to be
signed is now computed with a hash function before signing.
* Fixed the public key authentication from the server as well.
Affected file silcd/protocol.c.
* Removed the mlock()'s from the memory allocation routines.
Affected file lib/silcutil/silcmemory.c. The ./configure does
not check anymore for the mlock(). Affected file is
configure.in.pre.
* Fixed USERS command in server to allow the execution of the
command for private and secret channels if the client sending
the command is on the channel. Affected file silcd/command.c.
* Fixed silc_client_get_clients_local to return the clients
count correctly. It could return wrong value. Affected file
lib/silcclient/idlist.c.
Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
types. The assembler optimizations seemed not to like 64-bit
data types. The assmebler optimizations thus are now enabled
also for BSD systems as opposed to only enable them for Linux.
* Do not check for threads at all on BSD systems. Affected
file configure.in.pre.
* Removed -n and -h options from the Irssi SILC Client since
they are not used in silc.
* Fixed the prime generation to assure that the first digit
of the generated random number is not zero since our conversion
routines does not like number strings that starts with zero
digit. If zero digit is seen the random number is regenerated.
This caused some corrupted RSA keys when the zero first digit
was met. Affected file lib/silcmath/silcprimegen.c.
Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed WIN32 configuration in the ./configure script.
Fixed to include xti.h on environments that has it.
Patches by Carsten Ilchmann and andrew.
Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Changed the silc_id_create_client_id to be collision
resistant. It is now assured that there cannot be created
two same client ID's. I suspect that some weird bugs in
the server were actually caused by duplicate Client IDs.
Affected file silcd/serverid.[ch]. A router receiving
new ID now also assures and informs the sending server
if the ID caused collision.
* Changed the silc_id_create_channel_id to also assure that
there are no collisions.
Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Statement about ignoring the Mutual Authentication flag when
performing rekey with PFS was a bit misleading. It is ignored
if it was set in the initial negotiation, it cannot be even
set in the rekey. Fixed in the ke-auth draft. Started the
new versions of the protocol drafts in the doc/.
Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed a bug in silc_client_command_identify_save when saving
new channel information. The channel name was no duplicated
and caused crash on exit. Affected file is
lib/silcclient/command_reply.c.
Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed the getkey command handling in the server. Send just
empty OK reply to the sender if the key could not be fetched
(but everything else was ok, like the key just was not available).
Changed the public key parameter to optional in the protocol
specs so that empty OK reply can be sent. Affected file
silcd/command.c.
Added a message to Irssi SILC client to tell to user if the
server did not return a public key.
Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed a channel key regeneration bug. It registered new
timeout tasks exponentially until all system resources were
used. Affected file silcd/server.c.
Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Added the SILC Document generator to the scripts/silcdoc.
It can be used to generate the Toolkit Reference Manual out
of the source tree. Internally it will also use the RoboDoc
generator now imported in util/robodoc.
Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Added couple of return's in rekey protocol if error orccurred
during the protocol. The execution must be terminated.
Affected file silcd/protocol.c. Also, terminate the protocol
always with timeout.
Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* The client's Client ID was created initally from the wrong
nickname (it could have been in format nick@host) in the
silc_server_new_client. Affected file silcd/packet_receive.c
Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Added some SILC_LOG_ERROR's to various error conditions
if client could not be added to ID cache. Affected files
silcd/packet_receive.c and silcd/server.c.
* When client's sock->user_data is freed, NULL also the
client->router and client->connection pointers. Added check
for these pointers being NULL to various places around the
code. Affected file silcd/server.c.
* Added client->data.registered == TRUE checks to various
places around the code to assure that unregistered client's
are not handled when it is not allowed. Affected file
silcd/server.c.
* Added `bool registered' fields to all
silc_idlist_[server|client]_get_* routines to indicate whether
the fetched client needs to be registered or not. Affected
file silcd/idlist.[ch].
* Add your own entry as registered to the ID cache in the
server. Affected file server.c.
* Fixed a bug in silc_server_new_server. The SilcServer was
set as the new server's context instead of SilcServerEntry.
This naturally caused some weird bugs.
* Added "updated" field the SilcChannelEntry which indicates
the time since the channel entry was last accessed. This
can be used to determine whether it is necessary to
announce the channel after backup resuming protocol.
Affected files silcd/idlist.[ch].
Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Do not delete the channel rekey task when adding it
for in silc_server_create_channel_key.
* Changed the silc_server_create_channel_key to return
TRUE or FALSE to indicate the success of the channel key
creation.
Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed MSVC++ project files and added missing files to
Makefiles under win32/.
Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Do not add TCP_NODELAY flag if the operating system
does not have it defined. Affected files are
lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
* Fixed buffer overflow from Irssi SILC Client. Affected
file irssi/src/fe-common/core/themes.c.
* Fixed double free in client library in the file
lib/silcclient/client.c when disconnecting from server.
* Applied double free patch from cras to Irssi SILC client.
Affected files irssi/src/core/[modules/expandos].c
* Fixed the disconnection handling to Irssi SILC Client.
The application must call silc_client_close_connection
in ops->connect client operation in case of failure of
the connection. Affected file is
irssi/src/silc/core/client_ops.c.
* Do not set sock->protocol to NULL in the function
silc_client_close_connection after executing the protocol's
final callback since the sock might not be valid anymore.
Affected file lib/silcclient/client.c.
Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Do not enable SILC_THREADS if the linking with libpthread
did not happen. Affected file configure.in.pre.
* Added notion to protocol specification that server must
verify the sent authentication payload with CMODE when
setting the channel founder key. Implemented it to the
server. Affected file silcd/command.c.
Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Added _EXTRA_DIST SILC distribution variable to the
distributions file. It is used to conditionally add extra
files or directories to the specific distribution. Affected
files ./prepare, Makefile.am.pre and distributions.
Removed the `_' from the start of the distribution names.
It is redundant.
* Added README.WIN32 for instructions to compile the Toolkit
under WIN32.
Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed a double free in disconnection in the server. Affected
file is silcd/server.c.
* Fixed the lib/silcske/groups.c to work now also with GMP
MP library. The string conversion did not work when using
specific base and the base is indicated in the string as well.
* Created win32/ directory which now includes MSVC++ specific
stuff so that toolkit (DLLs) may be compiled with MSVC++.
It will appear only in the toolkit distribution
Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Changed the key material distribution function in case when
the hash output is too short. The data is now concatenated
a bit differently than it used to. Made the change to the
SKE protocol specification.
* Added better GMP detection to configure.in.pre. A patch
by salo.
Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed a minor bug in SKE that might cause some problem on
some platforms. Affected file lib/silcske/silcske.c.
* Added the cookie checking for initiator in the SKE. It checks
that the responder returns the sent cookie unmodified. The
affected file is lib/silcske/silcske.c. Added new SKE
error type INVALID_COOKIE that can be sent during the
negotiation. Fixed some memory leaks as well.
* Added the "invalid cookie" error message to Irssi SILC client's
message formats.
Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Added `task_max' field to the SilcClientParams to indicate
the maximum tasks the scheduler can handle. If set to zero,
default values are used. Affected file lib/silcclient/silcapi.h.
* Fixed memory leaks in silc_client_close_connection. Affected
file lib/silcclient/client.c.
* Added silc_client_del_client_entry to client library to free
all memory of given client entry. Affected file is
lib/silcclient/idlist.[ch].
* Added new functions silc_client_del_channel and
silc_client_del_server to delete channel and server entries.
Affected file lib/silcclient/[silcapi.h/idlist.c].
* Removed silc_client_del_client_by_id from silcapi.h.
* Fixed the INFO command to return the server's own info
correctly when querying by Server ID. Affected file is
silcd/command.c.
Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Removed the non-blocking settings in WIN32 code in the
silc_sock_[read/write] and added SleepEx instead. Affected
file lib/silcutil/win32/silcwin32sockconn.c. The availability
of input data is now checked with FIONREAD and ioctlsocket.
Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Call silc_schedule_task_del_by_context in the
silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
Affected file lib/silccore/silcprotocol.c.
* Call silc_protocol_cancel for active protocols in the
silc_server_close_connection if the funtion
silc_server_free_sock_user_data has not been called.
Affected file silcd/server.c.
* Generic tasks cannot be deleted using the del_by_fd
task deleting function since generic tasks does not match
any specific fd. Affected file lib/silcutil/silcschedule.[ch].
* Added a notion to SILCOPER help file that the SILCOPER works
only on router server, not on normal server.
Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Added for WIN32 support for the new scheduler as well.
Affected file lib/silcutil/win32/silcwin32schedule.c.
* Fixed the SHA1 implementation to work on various platforms.
Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Rewrote the SILC Scheduler entirely. Removed the old SILC Task
API. It is part of the scheduler now. Everything else is
as previously but some functions has changed their names.
Checkout the lib/silcutil/silcschedule.h for the interface.
Updated all applications to use the new interface. Affected
files are lib/silcutil/silcschedule.[ch].
Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Found a bug in the SKE implementation. The HASH value,
specified by the protocol, was not computed correctly. The
public key of the responder was not added to the computation
even though it is mandatory. Affected file lib/silcske/silcske.c.
This unfortunately causes incompatibilities with older
clients and servers.
* Added WIN32 specific network init and uninit functions:
silc_net_win32_init and silc_net_win32_uninit to init and uninit
the Winsock2. Affected file lib/silcutil/silcnet.h and
lib/silcutil/win32/silcwin32net.c.
* Set the socket always to nonblocking mode on WIN32 after
reading data or writing data. Affected file is
lib/silcutil/win32/silcwin32sockconn.c.
Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed various compilation problems under WIN32. Affected
files lib/silcutil/win32/silcwin32thread.c and
lib/silcutil/win32/silcwin32schedule.c.
* Removed all _internal.h #includes from public header
files. Internal headers must never be included from
public headers.
Removed also the lib/silcske/payload_internal.h file.
* All include files that may be needed (public and some others
included by the public headers) by application developers are
now copied to the ./includes directory. It does not copy any
internal headers. Affected file Makefile.defines.pre and all
Makefile.am's under lib/ and subdirs.
Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Do not change the ~/.silc directory's permissions automatically.
Affected file irssi/src/silc/core/clientutil.c.
Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Do not cancel the protocol in silc_server_close_connection
it might cause recursion. Now cancelled in the function
silc_server_free_sock_user_data. Affected file silcd/server.c.
* Fixed the silc_server_remove_clients_by_server to regenerate
the channel keys correctly finally. Added also new function
silc_server_remove_clients_channels to actually do it.
Affected file silcd/server.c.
* Fixed the silc_server_new_channel to not crash by giving
wrong router to the new channel. Affected file is
silcd/packet_receive.c.
Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Added SilcClientParams structure to the lib/silcclient/silcapi.h
which is given as argument to the silc_client_alloc now.
It can be used to configure the client and set various parameters
that affect the function of the client.
* The USERS command in server did not check whether the channel
is private or secret. Affected file silcd/command.c.
* Added new argument to the USERS command in protocol specification.
The USERS command now can take the channel name as argument
as well. Added support for this in client and server and
updated the protocol specs.
* Completed the GETKEY command in client. It can be now used
to fetch also servers public key not only some clients.
Affected files lib/silcclient/command[_reply].c.
* Added silc_client_get_server to return server entry by the
server name. Affected files lib/silcclient/silcapi.h and
idlist.c.
* Redefined the IDENTIFY command in protocol specification to be
more generic. It now can be used to query information about
any entity in the SILC Network, including clients, servers and
channels. The query may be based either the entity's name
or the ID. Added support for this in both client and server.
Affected files silcd/command.c and lib/silcclient/command.c
and command_reply.c.
* Optimized the WHOIS and WHOWAS commands in the server. Removed
the _from_client and _from_server functions. Affected file
silcd/command.c.
* Added silc_client_get_channel_by_id_resolve to the file
lib/silcclient/silcapi.h to resolve channel information by
its ID. Added also silc_client_get_channel_by_id that
does not resolve it from the server.
Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Added SilcServerEntry context into the client library
to represent one server. The INFO command now allocates
these to save the resolved server info. For now on the
client library will also keep information about servers,
connected and resolved with INFO.
The INFO command now allocates the SilcServerEntry context
and saves the server info there. The COMMAND_REPLY in
the INFO now returns the parameters to application in
same order as defined in the protocol specification.
The entries are cached in the client->server_cache.
* The INFO command is now issued after received the Client ID
from the server. Affected file lib/silcclient/client.c.
* The CMODE_CHANGE notify may now return also an SilcServerEntry
to the application as the mode changer might be server.
It is guaranteed that NULL is not returned anymore to the
application. Affected file lib/silcclient/client_notify.c.
The ID Type is now also passed to the application so that
it can check whether the returned entry is SilcClientEntry
or SilcServerEntry.
Added new function silc_client_get_server_by_id to return
the server entry by ID. Affected files are the
lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
* Do not create the channel in the Irssi SILC Client when issuing
the JOIN command but when received the sucessful JOIN command
reply. Otherwise the channel might get created even though we
could not join it. The Affected file is
irssi/src/silc/core/[silc-channels.c/client_ops.c].
* Fixed a channel joining bug in router. The router must also
check the channel modes, invite and ban lists etc. when serving
the JOIN command sent by normal server. Affected file is
silcd/command.c. The router now resolves the client's
information from the server who sent the JOIN command if it
does not know it, and processes the JOIN command only after
that.
* Changed the SilcCommandCb to take new argument; void *context2.
Affected file lib/silccore/silccommand.h
The second argument in the command callbacks in the server now
includes the SilcServerCommandReplyContext if the command was
called as pending command callback from the command reply.
Otherwise it is NULL. When called as pending the status of the
command reply will be checked and if it was erronous the
error will be sent to the original sender of the command.
This way the client always receives the error messages even
though the server was actually the one who received the error
when it resent the command to router, for example. Affected
files silcd/command[_reply].[ch].
* Fixed sending WHOWAS command's error message to client if
the requested client could not be found. It was missing.
silcd/command.c.
* Changed the CMODE and CUMODE commands reply arguments in the
protocol specification. The Channel ID is now sent in both
of the commands to identify the channel. Implemented this
new feature to the client and server. Affected files
lib/silcclient/command_reply.c and silcd/command.c.
* Made better checks for invite and ban lists in the JOIN
command in server. Affected file silcd/command.c.
Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* The server now performs the incoming host IP/DNS lookup
using the silc_socket_host_lookup and thus does not block
the server anymore. Affected file silcd/server.c.
* Completed the multi-thread support for SILC Scheduler in
the lib/silcutil/silcschedule.c.
* Fixed the configure.in.pre to detect the pthread correctly
on various systems.
* Fixed a deadlock in silc_task_queue_wakeup in the file
lib/silcutil/silctask.c.
Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Added new function silc_schedule_wakeup that is used in
multi-threaded environment to wakeup the main thread's
schduler. It needs to be used when a thread adds a new task
or removes a task from task queues. After waking up, the
scheduler will detect the task queue changes. If threads
support is not compiled in this function has no effect.
Implemented the wakeup mechanism to both Unix and WIN32
systems. Affected files are lib/silcutil/silcschedule.[ch],
lib/silcutil/unix/silcunixschedule.c and the
lib/silcutil/win32/silcwin32schedule.c.
* Added new function silc_task_queue_wakeup to wakeup the
scheduler by the specified task queue. Affected file
lib/silcutil/silctask.[ch].
* The silc_socket_host_lookup_start now wakes up the scheduler
after adding the timeout task. Affected file is
lib/silcutil/silcsockconn.c.
* The silc_socket_host_lookup is synchronous now if the threads
support is not compiled in. However, the callback is still
called asyncronously through the scheduler, anyway. Affected
file lib/silcutil/silcsockconn.c.
Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Added new function silc_socket_host_lookup to perform
asynchronous IP and FQDN lookups for the socket connection.
Affected files lib/silcutil/silcsockconn.[ch].
Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Added SILC_MUTEX_DEFINE to define the mutex on environments
that may or may not compile the mutex support in.
Changed the silc_mutex_alloc interface. It allocates the
mutex now to the sent pointer and returns TRUE or FALSE.
Affected file lib/silcutil/silcmutex.h.
* Wrote the SILC Task Queue interface to support multi-threads.
Affected file lib/silcutil/silctask.[ch].
* Wrote the SILC Scheduler to support multi-threads. Affected
file lib/silcutil/silcschedule.c.
Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Implemented the SILC Mutex API and SILC Thread API for WIN32
in lib/silcutil/win32/.
Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Defined SILC Mutex API and SILC Thread API and implemented
them for Unix. Affected files are
lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
lib/silcutil/unix/silcunixmutex.c and
lib/silcutil/unix/silcunixthread.c.
Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed the silc_server_remove_clients_by_server's channel
key re-generation. The hash table handling was incorrect
and would not work with many channels. Affected file is
silcd/server.c.
* Fixed some memory leaks around the server code.
* Rewrote the silc_server_get_users_on_channel to support IPv6
based Client ID's. Affected file silcd/server.c.
* Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
specification. However, a separate document must be written
to define the detailed signing procedure and the payload
associated with the flag. Defined the flag to the
lib/silccore/silcchannel.h as well.
Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Changed the dynamic tables to static size tables in the
lib/silccrypt/silchmac.c.
* Removed GCC dependencies from the code. A patch by cras.
Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Do not show the error "Error receiving packet bla bla"
in server if it really was not an error (-2 means that reading
is pending). Affected file silcd/server.c.
Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed a possible crash in silc_server_remove_clients_by_server
in silcd/server.c. Fixed there also some memory leaks.
* Fixed the silc_idlist_replace_client_id. It could replace
wrong key in the hash table. Affected file silcd/idlist.c.
* Do not check whether there are global users on the channel
if the channel->global_users is FALSE. Affected functions
silc_server_remove_from_one_channel and
silc_server_remove_from_channels in silcd/server.c. Also,
do not check if the removed client is local as we can be
sure that global client was not removed from the channel
and checking for global users is not needed.
* The silc_server_remove_clients_by_server now re-generates
the channel keys correctly for those channels that had
clients removed from them. Affected file silcd/server.c.
Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Found the reason of random crashes in the server. We weren't
ignoring the SIGPIPE signal (which can be sent in write())
and it crashed the server. Affected file silcd/silcd.c.
Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Assure that sock->user_data is not NULL in the function
silc_server_packet_send in silcd/packet_send.c.
* Disconnect the remote connection if it could not be added
to any ID lists in the server. The affected file is
silcd/server.c.
* Check in silc_server_packet_send[_real/dest] that the
socket is not disconnecting and ignore the data if it is.
Affected file silcd/packet_send.c.
* Define inline to __inline on native WIN32 compilation.
Affected file includes/silcwin32.h.
* Added some explicit type casts for inline code since MSVC
require them. Affected files lib/silcutil/silcbuffer.h,
lib/trq/silcdlist.h and lib/trq/silclist.h.
* Print warning in log files from now on if the packet
decryption fails. Affected file silcd/server.c.
Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Changed the `say' client operation's interface to accept
new `type' argument to indicate the type of the message sent
by the library. The application may filter the library's
messages according the type. The affected file is the
lib/silcclient/silcapi.h.
* Added two new functions to lib/silcclient/silcapi.h:
silc_client_del_client and silc_client_del_client_by_id.
Affected file lib/silcclient/idlist.c.
* Moved the clientincludes.h from includes/ to silc/ and
serverincludes.h from includes/ to silcd/.
* The modes for the CMODE and CUMODE are now passed as
uint32 for application with COMMAND_REPLY. The affected
file is lib/silcclient/command_reply.c.
Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* /WHOIS without arguments shows client's own information.
Affected file lib/silcclient/command.c.
* Changed PING to not accept any arguments. The specs
says that client can ping only the connected server so
requiring an argument is not needed. Affected file is
lib/silcclient/command.c.
Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Fixed a fatal bug in private message sending and reception
encryption and decryption when using private message keys.
The implementation was incorrect and did not follow the
specification. It causd that some of the message were
lost since it did not use the sending and receiving keys
as the protocol suggests. This has been fixed and will cause
incompatibilities with older clients when sending private
message encrypted with private message keys. Affected files
lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
and various other in Irssi SILC Client.
Added `responder' boolean argument to the functions
silc_client_add_private_message_key[_ske] to indicate when
the key is added as responder or initiator of the key
negotiation.
Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Removed the silc_ske_check_version function and created
a SilcSKECheckVersion callback. Added also a function
silc_ske_set_callbacks that is now used to set all SKE
callbacks. The callback functions are not given to
the SKE functions anymore, but this function is used to
set the callbacks.
* Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
* Added `silc_version' argument to the silc_client_alloc
to define the version of the application for the library.
The library will use the version string to compare it
against the remote host's (usually a server) version
string. Affected file lib/silcclient/silcapi.h
* Added the KE protocol context to Key Agreement context
in client library so that we can abort the SKE if it
is in process when we get timeout. Affected file is
lib/silcclient/client_keyagr.c.
* Do not resolve the client ID forever if it returns in the
first time that such client does not exist. This was done
for example with private message. Affected file is
lib/silcclient/client_prvmsg.c.
Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Do not add regex.h for WIN32. The affected file
includes/silcincludes.h.
* Added WIN32 DLL generation to lib/Makefile.am.pre. It might
not work yet 100%. It generates the DLL's automatically
when compiling with --with-win32 under cygwin.
Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* lib/contrib/regex.c is not compiled on WIN32.
* Added silc_net_get_socket_opt function to the
lib/silcutil/silcnet.h.
* Added includes/silcwin32.h for WIN32 specific includes
and definitions.
* Do not use ptime structure or any of the posix process
functions on WIN32 in lib/silccrypt/silrng.c.
* Added silc_gettimeofday to provide generic function
for struct timeval on all platforms. Added the function
to lib/silcutil/silcutil.h.
Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Moved the lib/silccore/silcsockconn.[ch] to the utility
library as they clearly belong there. As a plus side we
can make the actual socket connection routines platform
specific.
Added also new generic function silc_socket_read and
silc_socket_write (that used to be silc_packet_[read/write].
The implementation of these are platform specific.
* Added WIN32 specific routines of silc_socket_[read/write]
to lib/silcutil/win32/silcwin32sockconn.c.
Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Added preliminary support for native WIN32 compilation under
cygwin (using the -mno-cygwin option for GCC) to the
./configure.in.pre. The --with-win32 now prepares the
compilation for native WIN32.
* Rewrote the SILC Scheduler interface in the file
lib/silcutil/silcschedule.h. The scheduler is now context
based and does not have anymore any global static scheduler.
Moved the Unix scheduler to the lib/silcutil/unix/ directory
and created lib/silcutil/win32 directory for WIN32 based
scheduler.
* Added Unix specific network routines to the
lib/silcutil/unix/silcunixnet.c and the old
lib/silcutil/silcnet.c includes now only generic routines.
Added WIN32 specific network routines to the
lib/silcutil/win32/silcwin32net.c.
* Added Unix specific utility functions from the
lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
* Added WIN32 SILC Scheduler to the file
lib/silcutil/win32/silcwin32schedule.c. The code is of course
untested.
Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
* Do not handle JOIN notify in the server if the target client
is not registered (idata->registered == FALSE). The affected
file is silcd/packet_receive.c.
* Update the nickrec->founder in event_cumode in the Irssi SILC
client. Affected file irssi/src/silc/core/silc-channels.c.
* Fixed the CUMODE_CHANGE notify handling in the server when
server and router are announcing their clients on channels.
Now the mode changes are saved and notified correctly. The
affected file is /silcd/packet_receive.c.
* Fixed silc_idlit_replace_[server/client/channel]_id functions.
They really did not replace the cache entry in the ID Cache.
Now they do that. Affected file silcd/idlist.c.
* Fixed the KICK notify handling in the Irssi SILC client to
update the channel records so that the kicked client does not
appear to be on the channel. The affected file is
irssi/src/silc/core/silc-channels.c.
* Always update the conn->current_channel when executing command
on a channel. Affected file irssi/src/silc/core/silc-servers.c.
* Fixed the KILL notify handling in Irssi SILC client to remove
the killed client on all channels.
Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed the silc_parse_command_line to remove extra spaces
from the start and end of the arguments. Affected file is
lib/silcutil/silcutil.c.
* Cancel and free any active protocol in the function
silc_server_close_connection. Affected file silcd/server.c.
* Cancel and free any active protocol in the function
silc_client_close_connction. Affected file is
lib/silcclient/client.c.
* Do not execute the KILL command for clients that are in
history (ie. they are not in the network). Affected file is
silcd/command.c.
* Fixed KILL notify handling, client does not crash anymore.
Affected file irssi/src/silc/core/silc-channels.c.
* Reduced the default packet buffer size from 2048 to 1024 in
lib/silccore/silcpacket.c.
* Added SILC_SKE_STATUS_FREED SKE status type and a reference
counter to the SKE context that is incresed when the SKE library
performs async operation outside the library. If the outside
process frees the SKE context and FREED status will be set
and the library will detect after the sync operation that the
libary is freed. The affected files are
lib/silcske/silcske[_status].[ch].
* Resolve the client entry information in the function
silc_client_channel_message to assure that NULL pointer is not
passed as client entry to the application. */
* Fixed the task timeout calculation to assure that there is
never negative timeouts. The affected file is
lib/silcutil/silcschedule.c.
* Fixed the channel user mode notification sending in server.
It was sent point-to-point to the router (or to server by router)
but it needs to be destined to a channel. The routines now
supports sending the channel user mode notifys to the channels
when announcing clients and channels. Affected files are
silcd/server.c and silcd/packet_receive.c.
* Fixed the CHANNEL_CHANGE notify handling in the client libary.
It did not actually replace the old channel entry in the cache.
Affected file lib/silcclient/client_notify.c.
Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed a possible crash in silc_packet_send_prepare. It now
assures always that there is enough space in the buffer and
at the tail area of the buffer (for MAC).
Fixed the inbound buffer reallocation in silc_packet_read.
It was old code and did not handle the reallocation correctly.
Affected
The affected file is lib/silccore/silcpacket.c.
* Fixed buffer overflow in silc_parse_nickname in the file
lib/silcutil/silcutil.c.
Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* make install generates new server keys only if there is not
keys already.
Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
Added check that if the NOREPLY is set then we will not send
the away message. This avoids infinite loop of away messages
if both clients are away. The affected file is
lib/silcclient/client_prvmsg.c.
* Fixed client crash if /NICK was given without arguments.
Affected file lib/silcclient/command.c.
* Server does not send the invite list in INVITE command back
to the client if the list was not altered. Added this notion
to the protocol spec as well. Affected file silcd/command.c.
Fixed possible crash in INVITE command by checking the
value of silc_server_get_client_route command.
* Fixed the INVITE notify type handling. The arguments are now
taken in correct order and client does not crash. The affected
file is irssi/src/silc/core/silc-channels.c.
Removed the "Inviting xxx to channel" message from the
client library away and let the application handle it.
Affected file lib/silcclient/command.c. Added that message
to Irssi SILC client's message formats.
* Fixed CMODE command crash in client. It now checks the
amount of arguments correctly and does not crash. The affected
file is lib/silcclient/command.c.
* Do not create new channel automatically in silc_channels_join
but check whether the channel by that name already exists.
Affected file irssi/silc/core/silc-channels.c.
* Do not send the SERVER_SIGNOFF to router if the disconnected
entity was the router. Affected file silcd/server.c.
* Added the handling of the SERVER_SIGNOFF notify to the Irssi
SILC client as it was missing from there.
Added the handling of the KICK notify to the Irssi SILC client
as it was missing. Added "you have been kicked" message to
Irssi SILC client's message modules formats.
Added the handing of the KILL notify to the Irssi SILC client
as it was missing. Added the kill message module formats
as well.
The affected file is irssi/src/silc/core/silc-channels.c.
* The router did not save the channel mode the server announced.
Affected file silcd/packet_receive.c.
* Fixed a possible crash in INFO command in server. If the
server did not provide the server info it crashed. Affected
file silcd/command.c.
Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed the GETKEY command in the server to check also the
global list. Otherwise the GETKEY would not work correctly
in normal SILC server. Affected file silcd/command.c.
Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed GETKEY crash, it crashed if the command did not succseed.
Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
is now real and not just an macro interface to GMP.
Removed the entire GMP from the source tree and imported new
NSS MPI library instead. Reason for removing GMP is that it is
extremely large and compiles extremely slow. The NSS MPI
is only a few files and compiles in less than 10 seconds.
The speed is also about the same as GMP. The MPI is imported
to lib/silcmath/mpi.
If the system has GMP installed we will still use the GMP.
If it is not then the NSS MPI will be compiled.
Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Merged a long nickname (127 characters long) crash bugfix from
Irssi CVS tree. Affected file irssi/src/core/misc.c.
* Merged a freed memory reference bugfix from Irssi CVS tree.
Affected file irssi/src/core/commands.c.
Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added the server's public key sving and verification to the
server when performing the SKE. This was missing and the
remote server's (or router's) public key was accepted without
checking whether we have it previously or trust it at all.
Affected file silcd/protocol.c.
Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Check in the silc_server_timeout_remote if protocol is active
and make sure that the protocol's final callback is called so
that all memory if freed. Affected file silcd/server.c.
Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* silc_server_whois_send_reply crashed the server if the nickname
was 127 characters long. Affected file silcd/command.c.
Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added sanity check to the silc_server_new_client. If the hostname
is provided inside username then check that the provided hostname
really is the same as the resolved one. If the hostname was not
resolved then check it from the public key. Affected file is
silcd/packet_receive.c.
* Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
if the server disconnected us and the connection is not valid
anymore. Affected file irssi/src/silc/core/silc-channels.c.
* Moved the silc_client_[chmode|chumode|chumode_char] away from
the library to the lib/silcutil/silcutil.[ch].
Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Close log file after open. Affected file
lib/silcutil/silclog.c.
* Check whether sock == NULL in silc_client_send_packet and return
if it is. Affected file lib/silcclient/silcclient.c.
* Check rec->entry == NULL in the Irssi SILC Client before
sending the channel message. Affecte file is
irssi/src/silc/core/silc-servers.c.
Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Merged a splitted window bugfix from Irssi CVS tree. The
affected file is irssi/src/fe-text/textbuffer-view.c.
* Fixed the ME, ACTION and NOTICE printing in Irssi Client.
It did not print nickname.
* Improved the distributions system a bit.
Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Merged /WINDOW bugfix from irssi CVS tree. Affected file is
irssi/src/fe-text/gui-window.c.
* Fixed a fatal bug in Irssi SILC client. Crashed if sent message
to in-active server. The affected file is
irssi/src/silc/core/client_ops.c.
* Resolve the client in USERS command reply if the entry does
not have username resolved. The affected file is
lib/silcclient/command_reply.c. Also, changed the IDENTIFY
command to WHOIS command to really resolve stuff. The USERS
is not used any more in any critical section so WHOIS can
be used even though it might be slower than IDENTIFY.
* Changed the lib/silcutil/silchashtable.h header to ROBODoc
format.
Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Changed the protocol API a bit more consistent in the
lib/silccore/silcprotocol.[ch].
* Changed the following headers to ROBODoc format:
lib/silccore/silcpayload.h
lib/silccore/silcprotocol.h
lib/silccore/silcsockconn.h
All core library headers are now formatted.
Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed a bug in Irssi SILC client; do not show that you are
server/router operator if you really are not. Affected file is
irssi/src/silc/core/client_ops.c.
* Renamed silc_command_free_payload to silc_command_payload_free.
Affected file lib/silccore/silccommand.h
* Added silcmath.h to include the prototoypes of various routines
in the lib/silcmath. Removed the old modinv.h, mpbin.h and
silcprimegen.h.
* Changed the following headers to ROBODoc format:
lib/silccore/silcchannel.h
lib/silccore/silccommand.h
lib/silccore/silcid.h
lib/silccore/silcidcache.h
lib/silccore/silcmode.h
lib/silccore/silcnotify.h
lib/silccore/silcpacket.h
lib/silcmath/silcmath.h
Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added checking to the server code not to start the server if
ciphers and stuff are not configured properly. Affected files
silcd/serverconfig.[h] and silcd/server.c.
* Changed the layout of the header files of the public interfaces
in the SILC libraries. The new layout supports ROBODoc
documentation tool (and some others) so that it is easy to create
a library reference manual. All the other headers and source
code must still follow the CodingStyle document. Also source
code must not include these ROBODoc stuffs, only the headers.
Furthermore, all public interface headers must now be named
by using `silc' prefix, example: silcapi.h, silccipher.h.
Some files were renamed due to this. All the other headers
must not be used as public interfaces. I will update the
CodingStyle document later. Changed following headers, so far:
lib/silcclient/silcapi.h
lib/silccore/silcauth.h
lib/silccore/silcprivate.h
lib/silccrypt/silcdh.h
Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Updated TODO.
* Removed silc_client_packet_send_flush from the client library
as it is not needed. Affected file lib/silcclient/client.[ch].
* Added printing of message of unresolved authentication method
to the Irssi SILC client. Added it to the module formats.
Removed the same message from the client library.
Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added new distribution feature, DISTLABEL. Every distribution
can define own preprocessor label that can be used in the
source code. For example: #ifdef SILC_DIST_CLIENT. Affected
file distributions, acconfig.h.pre and prepare.
Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added Makefile.defines_int to include the actual definitions
for Makefile.defines.in. Tested the new distribution system,
created distributions and tested installation.
* Added AWAY message printing to the Irssi SILC client. Added
the messages to the irssi/src/fe-common/silc/module-formats.[ch].
* Added SCONNECT command to call the SILC's CONNECT command.
Cannot use CONNECT directly since Irssi uses that internally.
Affected file irssi/src/silc/core/silc-servers.c.
Added ACTION local command. It is same as ME command but takes
the channel as mandatory argument.
Rewrote some of the Irssi's help files to suite for SILC
protocol.
Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added Makefile.defines[.in] that should for now on be included
in all Makefile.am file in the source tree. That file includes
all common compilation definitions for SILC source tree.
Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Minor changes to the ./prepare script to change the package
name according the distribution name to the configure.in.
Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Created new distribution system. Added file `distributions'
that defines all the distributions that can be created out of
the SILC source tree. The ./prepare script now reads that
file to determine how to prepare the distributions. The
first argument to the ./prepare is the name of the distribution
and second is the version of the distribution. If given
without arguments it creates the default (toolkit) distribution
with the default version (defined in ./prepare).
All Makefile.am files that are subject to the distributions
are now named as Makefile.am.pre. These are ./Makefile.am
and lib/Makefile.am. Others may be changed later.
Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added invite list, ban list, some key management and connection
error message printing to module formats in the Irssi SILC client.
* Added new silc_client_set_away_message to set the away message
that is back to the person who sent private message. The
affected file lib/silcclient/silcapi.h and the
lib/silcclient/client_prvmsg.c.
Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed the private message sending in the Irssi SILC client,
added local command KEY to the Irssi SILC client.
Added key management and key agreement message formats to the
irssi/src/fe-common/silc/module-formats.[ch].
Added USERS (alias WHO) printing, server/router operator
indication and LIST command printing to the module formats.
Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed channel joining notify handling, cumode notify handling
from Irssi SILC client.
* Added SILC specific module-formats to the Irssi SILC client so
that SILC specific message hilighting, colors etc is possible.
Affected file irssi/src/fe-common/silc/module-formats.[ch].
Added channel mode, channel user mode, actions, notices,
whois and whowas printing to the the module-formats.c.
* Fixed a bug in channel deletion in the server. The channel
is not left to the cache even if the channel founder auth mode
is set when there are no users anymore on the channel. Affected
file silcd/server.c.
* The silc_net_localhost now resolves the entire hostname including
the domain name. Affected file lib/silcutil/silcnet.c.
Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Changed the ask_passphrase client operation to be ascynchronous.
It has now a completion callback and a context that the
application must call after it has got the passphrase from
the user. Affected files lib/silcclient/silcapi.h,
lib/silcclient/protocol.c, lib/silcclient/command.c and
silc/client_ops.c.
Added SilcAskPassphrase callback that the application calls
to deliver the passphrase to the library.
* Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
The public key verification and especially a certificate
verification is asynchronous procedure.
Added new SILC_SKE_STATUS_PENDING status to indicate the
request is pending and a callback will be called to finalize
the request.
Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
indicate that remote end did not send its public key (or
certificate), even though we require it. Added check for this
condition in the SKE. This was a security bug, now fixed.
Defined new SilcSKEVerifyCbCompletion callback that is called
when the verification process is completed.
The affected files lib/silcske/silcske_status.h and
lib/silcske/silcske.[ch].
* Changed the verify_public_key client operation to be async
as well. Defined SilcVerifyPublicKey callback that is used to
indicate the success of the public key verification process.
Changed the server and client to use the new async client
operations.
* Changed the Irssi SILC client's internal scheduler to be called
twice as many times as it used to be. As a result the client
should be a bit faster now. Affected file is
irssi/src/silc/core/silc-core.c.
* Added support to Irssi SILC client of asynchronous public key
verification and passphrase inquiry. Affected file is
irssi/src/silc/core/silc-core.c.
Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Do not say "You have left channel %s" in client library.
Moved it to the application. Affected files are
lib/silcclient/command.c and silc/client_ops.c.
* Fixed silc_client_get_clients. Command context was not
duplicated and was freed memory in the callback. Affected
file lib/silcclient/idlist.c.
* Do not say "you are now talking..." on JOIN command in the
client library. The appliation must handle it.
* Do not say ".. changed topic to" in command reply in the
client libary. The application must handle it.
* Fixed TOPIC command sending in the client library.
* Fixed a memory leak in silc_client_command_free in the file
lib/silcclient/command.c.
Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Imported a modified version of Irssi client to the source tree.
The Irssi will be used to create a new client called
Irssi SILC. Imported to irssi/.
Added silc_core_init_finish function to the Irssi. Affected
file irssi/configure.in.
A lot changes in the Makefile.ams around the irssi tree.
Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Do not rehash if the new size is same as the old size of the
hash table, in the silc_hash_table_rehash*. The affected file
lib/silcutil/silchashtable.c.
* Replaced hash_table_del_by_context calls from the server
(when channel->user_list and client->channels) to the
hash_table_del as it is sufficient and faster.
Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added silc_hash_table_list, silc_hash_table_get and the
SilcHashTableList structure to provide an alternative way to
traverse the hash table. The affected files are
lib/silcutil/silchashtable.[ch].
* Changed the server's idlist routines to use the hash table
routines to optimize the code.
Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Replaced the client entry's `channel' list and channel entry's
`user_list' list to hash tables for optimized lookup. Changed
the code to use the hash table interface around the code.
Affected file lib/silcd/idlist.[ch].
* Added `auto_rehash' boolean argument to the function
silc_hash_table_alloc to indicate whether the hash table should
auto-rehash when it thinks is appropriate time. It will
increase the hash table size if the there is twice as much
entries in the table than the size of the table, and will
decrease the size if there are twice as less entries than
the size of the table.
Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed silc_xxx_get_supported to not crash at some circumstances.
Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* silc_idcache_purge_by_context deletes the entry now by context
as it is supposed to do. Affected file lib/silccore/idcache.c.
* Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
client is not anymore valid (WHOWAS givens the info) and not
the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Removed the `data' and `data_len' arguments from the ID Cache
interfaces and added `name' argument. ID Cache does not handle
anymore the binary data only a names associated with given ID.
* When hashing a Client ID with silc_hash_id the entire ID is
not hashed anymore, instead only the hash of the Client ID is
hashed. This way we can access the Client ID from the cache
with Client ID but with the hash of the ID (which is a hash of
the nickname) as well without any difference in performance.
Added also silc_idcache_find_by_id_one_ext to do one on one
searching when we have the actual ID. Added also function
silc_hash_client_id_compare. The affected files are
lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
* When hashing the name associated with a ID it is always done
in lowercase. This way we can access the cache without worrying
about case-sensitivity, even though, for example nicknames are
case sensitive.
* Fixed a bug in server with channel message sending. It put
wrong ID type as destination ID. The affected file
silcd/packet_send.c.
* silc_idcache_del_by_context now deletes from all hash tables
by context. Affected file lib/silccore/idcache.c.
Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Changed the client library to use the new ID Cache interface.
Changes around the source tree.
* Added silc_hash_table_rehash_ext to rehash with specific
hash function. Affected file lib/silcutil/silchashtable.[ch].
* Added silc_hash_string_compare to compare two strings in the
hash table. Affected file lib/silcutil/silcutil.[ch].
Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added new function silc_idcache_del_by_context into the
lib/silccore/idcache.[ch].
* Changed the server's ID list routines to use the new ID Cache
interface. Changes around the source tree.
Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added silc_hash_table_del[_by_context]_ext functions in to the
lib/silcutil/silchashtable.[ch].
Removed silc_hash_table_find_all* routines and added new
silc_hash_table_find_foreach to replace them.
Added silc_hash_table_replace_ext function as extended
replacing function. Separated the simple hash table interface
from the extended hash table interface in the file
lib/silcutil/silchashtable.h.
* Fixed minor bugs and changed it to use some of the new
hash table functions in lib/silccore/idcache.c
Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added new function silc_hash_table_find_all to return all keys
in the hash table by the specified key. As the hash table is
collision resistant it also makes it possible to have several
duplicate keys in the hash table. This function may be used to
find all of the keys from the hash.
Added user_context arguments to the SilcHashFunction,
SilcHashCompare and SilcHashDestructor to deliver user specified
context.
Added new fuctions silc_hash_table_find[_all]_ext to do
extended lookup with specified hash and compare functions and
specified user contexts.
Added new function silc_hash_table_add_ext to add the key
with specified hash function and user context.
Added new function silc_hash_table_foreach to traverse all
entrys in the hash table. Added SilcHashForeach callback
function.
Added new function silc_hash_table_del_by_context to delete
the entry only if the context associated with the key matches.
Affected files are lib/silcutil/silchashtable.[ch].
* Removed silc_hash_[server/client/channel]_id and added just
silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
silc_hash_id_compare to compare two ID's using as the hash table
comparison function. Added also silc_hash_data to hash
binary data and silc_hash_data_compare to compare it.
* Removed silc_idlist_find_client_by_hash as it is not needed
anymore. Affected file silcd/idlist.[ch].
* Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
to use internally the SilcHashTable. The new ID Cache is a lot
faster than the old one. Some of the ID Cache interface was also
rewritten and obsolete and stupid functions were removed.
Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added entry_count field to the SilcHashTable to keep the number
of the entries in the table. Implemented the function
silc_hash_table_rehash. Added new function
silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
Fixed a minor bug in silc_hash_table_free.
* Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
into the lib/silcutil/silcutil.[ch].
Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Implemented a collision resistant hash table into the
lib/silcutil/silchashtable[ch]. See the header and the source
for the SilcHashTable API.
Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Merged dotconf version 1.0.2 into lib/dotconf.
Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Do not compile anything in lib/silcsim/* if the SIM support
is not enabled. The tree should now compile without problems
under cygwin.
Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Compiled the SILC under cygwin. Compiled and tested briefly
without problems. More tests needed. The SIMs didn't compile
though.
* Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
* Fixed possible crash in silc_get_username in the
lib/silcutil/silcutil.c.
Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed a va_arg in silc/client_ops.c.
* Oops, RC5 routines were named AES and caused some problems
when not using SIM's. Affected file lib/silccrypt/rc5.c.
Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added new SilcIDIP structure into the lib/silccore/id.h and
replaced the old `ip' fields from all SILC ID's to that type.
This is a step towards IPv6 support.
The silc_id_get_len takes now the ID as an extra argument.
The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
both IPv4 and IPv6 based ID's.
The affected files are lib/silccore/id.[ch] and other files
around the tree using these routines.
* Removed the ID length arguments in server from various
silc_server_send_notify_* routines -> they are not needed
anymore.
Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed memory leak in silc_encode_pem_file in the file
lib/silcutil/silcutil.c.
Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Check minor version as well in the SKE. Affected files are
silcd/protocol.c and lib/silcclient/protocol.c.
* Added --identifier option to the server so that an identifier
can be when creating the public key for the server. Affected
file is silcd/silcd.c.
* Fixed minor decoding bug in silc_pkcs_decode_identifier in
lib/silccrypt/silcpkcs.c.
Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Register default ciphers and stuff when using -C option with
the server. Affected file sildc/silcd.c.
* Put back the servers public key filename format, it is better
than the new one. For now, the client keys are saved with the
new filename format. The affected file silc/client_ops.c.
* Implemented the Cipher API for the rest of the ciphers that
did not implement it or implemented it the wrong way.
Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Register default ciphers and stuff when using the -S option
in the client. Affected file silc/silc.c. Same also when
creating new key pair with -C option.
Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed the silc_verify_public_key client operation function to
save the public keys differently. The fingerprint is now
used as filename and not the hostname. This way also the
client keys are saved uniquely and not with hostnames. The
affected file is silc/client_ops.c.
* Trimmed the silc_hash_fingerprint function to remove extra
whitespaces from the end of the fingerprint. The affected
file is lib/silccrypt/silchash.c.
* Updated TODO.
* Added silc_cipher_register_default function to register all
default ciphers. It can be used when configuration files
does not exist and the application does not want any specific
ciphers in any specific order.
The SilcDList is now used as silc_cipher_list dynamically
allocated cipher list. Removed the static list all together
and now all ciphers must be allocated to the dynamic list.
The silc_cipher_alloc routine was changed to check only the
dynamic list.
All silc_cipher_* routines that used to return int returns
now bool.
The affected files lib/silccrypt/silccrypt.[ch].
* The same thing was done to silc_hash_* as for silc_cipher_*
routines. Affected files lib/silccrypt/silchash.[ch].
* The same thing was done to silc_pkcs_* as for silc_cipher_*
routines. Affected files lib/silccrypt/silcpkcs.[ch].
Added also silc_pkcs_[un]register[_default] functions.
Removed the data_context from the PKCS API.
* Added silc_hmac_register_default function to register default
hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
to unregister all hmacs at once.
* Register the default ciphers, hash functions, PKCSs and HMACs
if client's configuration file does not exist. The affected
file silc/silc.c.
* The client did not load the hash functions from the SIM
modules at all. Added support for this. Affected file is
silc/clientconfig.c.
* When decoding public key with silc_pkcs_public_key_decode, check
the supported algorithm only if PKCS are registered. Affected
file lib/silccrypt/silcpkcs.c. The same was done with the
silc_pkcs_private_key_decode.
* Fixed the SILC List routines to keep the list always in order.
It used to change the list's order when traversing the list but
not it preserves the order. Affected file lib/trq/silclist.h.
Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added the client library to use the SilcSocketConnection's
reference counter (by silc_socket_dup) to prevent the bug that
the socket object may be freed underneath async operation.
* The name resolv library checking fixes in the configure.in.pre.
The patch by salo.
* Created new version of the protocol drafts for future
development. The -03 drafts are the ones that will be changed
in the trunk now and the -02 will remain as they are.
* Send list of CUMODE notifys to the router when announcing
the channel users to the router. Affected file silcd/server.c.
If the router receiving channel founder CUMODE for a channel
that already has channel founder it will send CUMODE notify
to the sender to remove the channel founder rights from the
announced client. Affected file silcd/packet_receive.c.
* The CUMODE notify may now use Server ID as well as the entity
who changes the mode. Updated protocool specs.
* Updated INSTALL and README files.
Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* New web pages in the http://silc.pspt.fi. The pages was
designed by salo.
* Updated CREDITS.
Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Implemented the [DenyConnectin] config section in the server.
Added silc_server_config_denied_conn to check whether incoming
connection is denied. Affected file silcd/serverconfig.[ch].
* Do not check the ports when checking the incoming configuration
data if the port is 0, meaning any. Affected file is
silcd/serverconfig.c.
Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed buffer overflow in silc_string_compare in the file
lib/silcutil/silcutil.c.
* Fixed double free in silc_server_command_leave in the file
silcd/command.c.
Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed the version checking in the server. Affected file is
silcd/protocol.c.
Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed the configuration data fetching when accepting new
connections in the server. Affected file silcd/server.c.
Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added `sender_entry' argument to the function
silc_server_packet_relay_to_channel so that we can check
whether some destination actually belongs to the same route
the sender belongs (ie, we must not resend the packet to the
sender). Affected file silcd/packet_send.[ch].
* Added `servername' field to the SilcClientEntry in the server
to hold the name of the server where client is from. Affected
file is silcd/idlist.h.
Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Moved the channel message encrypting in the router betwen
router connections from silc_server_channel_message to the
silc_server_packet_relay_to_channel since we want to check
whether we have anybody channel before encrypting anything.
Affected files silcd/packet_[receive/send].c.
Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed the [AdminConnection] server config section to support
multiple entries. Affected file silcd/serverconfig.c.
* Added support into the server to check the validity of the
incoming connection before executing any KE or authentication
protocols.
* The connection configuration is now saved to the KE and
connection auth protocol contexts and not fetched anymore in
the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
* The local hosts listenning address and port is also resolved
now when starting the server. We want to have the socket object
to include the real address and port for the listener. Added
new function silc_net_check_local_by_sock into the files
lib/silcutil/silcnet.[ch].
* Fixed a broadcast bug in server -> do not broadcast if we
are standalone.
* Fixed a routing bug. Do not route broadcast packets ever.
Broadcast packets must be processed always and not routed since
they may be destined to some other host than yourself and thus
would get routed without no good reason. Affected file is
silcd/server.c.
* Added function silc_server_config_is_primary_route to check
whether primary router connection has been configured (a router
configuration that we are initiating). If there is not, we
will assume that there is only two routers in the SILC network
and we will use the incoming router connection as our primary
route. Affected files silcd/serverconfig.[ch], silcd/server.c.
* Changed the order of the broadcasting. Broadcast _after_ the
packet has been processed not before. Affected file is
silcd/server.c.
* Fixed a [ClientConnection] parsing bug. The port was never
parsed correctly thus resulting to port 0. Affected file
silcd/serverconfig.c.
* Fixed silc_server_send_notify_args -> it ignored the `broadcast'
argument and did not set the broadcast packet flag. Affected
file silcd/packet_send.c. Fixed same bug in the function
silc_server_send_notify as well.
* If we receive NEW_ID packet for our own ID in the server, ignore
the packet.
Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Updated TODO.
* Removed the nickname from the Private Message Payload.
Updated the code and the protocol specs.
* Updated protocol specs for submitting to the IETF.
* Tweaked the Random Number Generator a bit. Affected file
lib/silccrypt/silcrng.c. Exported a new function
silc_rng_[global]_add_noise which can be used to add more
noise to the RNG.
Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Do not parse packets with different timeout when protocol
is active -> may cause problem with rekey. Affected file
silcd/server.c.
* When server receives signoff notify it must not create
new channel key if the client is on any channels since the
sender of the signoff notify will create it.
Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added printing of error messages during SKE protocol from the
failure packet sent by server during SKE. Affected file
silc/client_ops.c.
* Removed the client's failure_callback handling with timeout
and handle it immediately when received.
* The SKE library returned wrong type in SUCCESS and FAILURE
packets. They must be 32 bit MSB not 16 bit MSB.
Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Ok, rewrote the logic of the re-key and now it seems to work.
I tested it on high traffic with frequent re-keys without
problems. Added hmac_receive (and renamed hmac to hmac_send)
in SilcClientConnection in lib/silcclient/client.h and
in SilcIDListData in silcd/idlist.h. Also, removed the
SilcPacketParserContext's cipher and hmac fields as they are
not needed anymore and actually caused some problems when
the ciphers and hmac's changed underneath the packet parser.
Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* If re-key protocol is active then process the incoming packets
synchronously since we must assure that icoming packets encrypted
with the old key is processed before the new keys is set to
use. This is true other packets than for REKEY packets.
Affected file silcd/server.c. The same was done to client library
as well, affected file lib/silcclient/client.c.
Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed bug in client and server to accept the force send if
the packet is send from silc_[server/client]_packet_process
function. Otherwise the packets are never delivered, oops.
Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Disable force sending of packets when REKEY protocol is active.
We must assure that no packet is sent directly when rekey is
performed. All packets must be sent through packet queue.
Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
function is silc_[server/client]_packet_send_real to check
the situation.
* Replaced the SIM paths from example config files to
/usr/local/modules. Also, make install creates now
/usr/local/silc/logs directory to hold all the SILC server
logs.
Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

IP/DNS could not be resolved. Though, it returns the IP address
now even if it could not resolve it (but returns also FALSE).
Affected file lib/silcutil/silcnet.[ch].
Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

contents of the specified public key file.
* Changed the PKCS api to return the public key length when
setting the public key.
* Fixed a fatal bug in the public and private key file loading.
Affected file lib/silccrypt/silcpkcs.c.
* Execute the packet parsing for client with zero (0) timeout
if the protocol is active. Affected file silcd/server.c.
Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Made the key generation options to the silcd program. Added
-C option, equivalent to client's option.
* Added new [ServerKeys] config section to the server. It
configures the server's public and private key.
* Defined generic Public Key Payload into the protocol
specification to send specific type of public keys and
certificates.
* Defined new command SILC_COMMAND_GETKEY to fetch a client's
public key or certificate.

* Added SilcServerRekey context into silcd/idlist.h.
* Added the PFS support as defined in the specification to the
SKE protocol. Affected files lib/silcske/*.c.
* Added `ske_group' field to the SilcServerRekey context to hold

Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Do not ask whether user wants to use the negotiated private key
for private messages, just use it. Affected file is
silc/local_command.c.
* Added `send_enc_key' and `enc_key_len' fields to the
SilcIDListData structure since they are needed in the re-key
phase. Affected file is silcd/idlist.[ch].

unsgined short to uint16 in the source tree.
* Fixed a fatal bug in silc_server_remove_clients_by_server. Do
not handle clients that has entry->data.registered == FALSE.
They are not in the network anymore. Affected file is
silcd/server.c.
Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Implemented the sending of the SERVER_SIGNOFF notify in the
server. Affected file is silcd/server.c.
* Added silc_server_send_notify_args into silcd/packet_send.[ch].
Added also silc_notify_payload_encode_args into the
lib/silccore/silcnotify.[ch].
* Implemented ther SERVER_SIGNOFF notify handling in the server.
Affected file silcd/packet_receive.c.

implemnted the printing of the SERVER_SIGNOFF info to the
application. Affected file silc/client_ops.c.
* The silc_idlist_del_server now returns TRUE or FALSE to indicate
if the deleting was successful. Affected file silcd/idlist.[ch].
* Added support for public key authentication in the connection
authentication protocol in the client library. Affected file
lib/silcclient/protocol.c.
* Changed the server's silc_idlist_get_clients_by_* interface
to support already allocated array so that new entries may be
added to pre-allocated array. Affected file silcd/idlist.[ch].
This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
and command replies.
* All command reply functions in the server now calls the
pending command callback even if error occured. This way the
error will be delivered to the client as well. Affected files
silcd/command.c and silcd/command_reply.c.
* Fixed INFO command to return local server's info if no server
was provided. Affected file lib/silcclient/command.c.
* Removed RESTART command for good. Updated the code and the
protocol specs.
* Rewrote parts of the task system. It is a bit simpler now.
Removed unsued task priorities. The affected files are
lib/silcutil/silctask.[ch].
Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Moved the USERS printing from the library to the application.
Affected files lib/silcclient/command.c and silc/client_ops.c.
Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Updated TODO.
* Added channel key re-key support. The re-key is perfomed
only by the router and is done once in an hour. Added `rekey'
field to the SilcChannelEntry in the server. Affected files
silcd/server.c and silcd/idlist.h.
* Added silc_task_unregister_by_context into the file
lib/silcutil/silctask.[ch].
Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added SILC_UMODE_GONE mode to indicate when the client is not
present in the SILC network. Added also support to the local
command AWAY that will set this mode. Added support of showing
"xxx is gone" in WHOIS command. The USERS command shows the
gone status as well.
* Fixed setting server and router operator privileges in the
server's UMODE command. Affected file silcd/command.c.
* Merged the SKE KE1 and KE2 payloads into one payload. The
new KE payload is equivalent to the old KE2 payload.
Cleaned up the SKE Start Payload parsing. It now uses the
simple buffer unformatting to do the parsing. A lot faster
now.
Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
to the SKE that is used to indicate whether both of the SKE
parties should perform authentication. By default only the
responder performs authentication. By setting this flag also
the initiator must do authentication. By default it is unset
since in normal SKE case, client to server connection, only
the responder should do authentication. When doing SKE between
two clients both should perform authentication. Updated the
code and the protocol specs.
* A little fix to IDENTIFY command in the server. Search the
client first by hash not nickname. Affected file is
silcd/command.c.
* Fixed the silc_client_close_connection to support closing
the client to client connections wihtout deleting too much
data. Affected file lib/silcclient/client.c.
* Fixed a fatal bug in server and client; if KE1 or KE2 packets
are received if protocol used to be active but is not anymore
the application would crash due to NULL pointer dereference.
Affected files silcd/server.c and lib/silcclient/client.c.
* Added `hash' field to the SilcClientConnection to include
the hash function negotiated in the SKE protocol.
* Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
to set the channel founder authentication data. A client can
claim the founder rights later by providing the authentication
data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
This way the channel founder can regain the channel founder
privileges even it is left the channel. This works only on
local server and the client must be connected to the same
server to be able to regain the founder rights. Updated the
protocol specs accordingly.
Added support to the CMODE command in the client to set the
founder auth data. Read the README to see how to set it.
Added support to the CUMODE command to claim the founder
rights. Read the README to see how to do it.
Added support for the founder authentication to the Channel
Entry in the server. Affected file silcd/idlist.h.
Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
server's CMODE command. Affected file silcd/command.c.
* Added the following new functions into lib/silccore/silcauth.[ch]:
silc_auth_get_method and silc_auth_get_data.
* The server now saves the remote hosts public key to the
SilcIDListData pointer. Affected file silcd/protocol.c.
* The normal server now does not remove the channel entry from
the cache if the founder authentication data is set. It used
to remove it if the founder was the last one on the channel on
the server and left the channel. The auth data is saved and
if the channel is re-joined later the old entry is used with
the old auth data. Affected files silcd/command_reply.c and
silcd/server.c.
* Removed the `pkcs' field from the SilcIDListData structure
in the server; it is not used. Affected file silcd/idlist.h.
Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed packet processing on slow links. Partial packets were
never re-processed because the incoming data buffer was cleared
by the application. Application must not directly clear the
sock->inbuf, the packet processing routines handle it. Fixed
this in client library and in server.
Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed the WHOIS and IDENTIFY send reply function to really
check whether to send list or just one entry. Affected file
silcd/command.c.
* Cleaned up the LEAVE command's channel key distribution. The
affected file silcd/command.c.
* Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
can enforce the channel mode as well. In that case the ID
includes the ID of the server. The code now enforces the
mode change if the router have different mode than the server.
* The notify client operation with CMODE_CHANGE notify can now
return NULL client_entry pointer if the CMODE was not changed
by client. Application must check for this.
* Added <Server ID> argument to INFO command to support server
info fetching by Server ID.
* Added silc_server_announce_get_channel_users to get assembled
packets of channel users of the specified channel. Affected
file silcd/server.[ch].
* Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
was freed underneath the ID Cache.
* Re-announce clients when the server received CHANNEL_CHANGE
notify from the router. Affected file silcd/packet_send.c.
Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
crashed since it did not handle the fact that there is no cipher
called "3" and didn't check the error condition. Now fixed.
* Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
flag. It can be used to send message requests.
Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Implemented the RESTART command in the client.
* Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
notice type messages. Added notice printing to the user
interface.
* The channel keys are not re-generated if the channel's mode
is PRIVKEY, ie private key on the channel exists. Affected
files silcd/server.c and silcd/command.c.
* Fixed a little bug in channel message delivery when channel
private keys are set in the server. Affected file is
silcd/packet_send.c.
* Changed the setting on channel->on_channel = TRUE from the
silc_client_save_channel_key to the JOIN command reply. The
key payload is not received if the private channel key is set.
Affected file lib/silcclient/command_reply.c and the
lib/silcclient/client_channel.c.
* When the CMODE_CHANGE notify is sent and the channel private
key mode is removed the channel key must be re-generated in
other cells as well. Added this support for the router in the
silcd/packet_receive.c.
* Added new local command NOTICE to send notice message on
channel. Affected file silc/local_command.[ch].
Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added new local command ME to the client. It is used to send
message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
some action. Affected file silc/local_command.[ch].
* Changed channel_message and private_message client operations
to deliver the message flags to the application. Added also
the `flags' arguments to the silc_client_send_channel_message
and silc_client_send_private_message functions. Affected file
silcapi.h.
Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Redefined the Private Message Payload to support private message
keys and to support the new private message flags. Updated
the protocol specs. Flags makes it possible to have for example
CTCP style messages.
* Added new type SilcPrivateMessagePayload and defined an API
for it in the lib/silcclient/silcprivate.[ch].
* Tested private message private keys successfully. Tested the
private message key set, unset and list commands with the new
KEY command.
* Redefined the Channel Message Payload to include the channel
message flags (equal with private message flags) to support
for example CTCP style messages.
* Defined some of the message (for channel and private message)
flags. Updated the protocol specs and added the flags to the
lib/silccore/silcchannel.h. The type is SilcMessageFlags.
Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added SilcKeyAgreementStatus type to the key agreement routines
to indicate the current status and error if one occured.
The status types are defined in the lib/silcclient/silcapi.h.
* Added new local command KEY that is used to set and unset private
keys for channels, set and unset private keys for private messages
with remote clients and to send key agreement requests and
negotiate the key agreement protocol with remote client. The
key agreement is supported only to negotiate private message keys,
it currently cannot be used to negotiate private keys for channels,
as it is not convenient for that purpose.
* Fixed a minor pending callback setting bug in the function
silc_client_get_client_by_id_resolve, now the function works.
Affected file lib/silcclient/idlist.c.
* Added function silc_net_get_local_port to get local bound
port by socket. Added to lib/silcutil/silcnet.[ch].
* Added `sockets' and `sockets_count' fields to the SilcClient
object. They hold the sockets of the listenning sockets in
the client. Listenning sockets may be for example the key
agreement server. Affected file lib/silcclient/client.[ch].
Added functions the silc_client_add_socket and the
silc_client_del_socket. They are exported to the application
as well.
* Added ~./silc/clientkeys to support other client's public keys.
* Renamed verify_server_key client operation to verify_public_key
and added one argument to indicate the type of the connection
(server, client etc.).
Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added silc_server_connection_auth_request to handle the
incoming CONNECTION_AUTH_REQUEST packet. Affected file is
silcd/packet_receive.[ch].
* Added silc_server_send_connection_auth_request into the
silcd/packet_send.c to send the connection auth request packet.
* Cleaned up the silcd/protocol.c a bit and fixed some memory
leaks.
* Fixed the public key authentication in responder side in the
server. The `auth_data' pointer includes the SilcPublicKey
not the path to the public key. Affected file silcd/protocol.c.
* Implemented the public key authentication in the initiator side
in the server. Affected file silcd/protocol.c.
* Removed the [RedirectClient] config section from the server
configuration. Is not needed and I don't want to implement it.
Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Cleaned up the CMODE command in the server. It now works
correctly and supports all the modes defined in the protocol.
Affected file is silcd/command.c.
* Added `hmac_name' field to the SilcChannelEntry in the server
to hold the default HMAC of the channel. It can be set when
creating the channel (with JOIN command). Affected files
silcd/idlist.[ch].
* Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
type to indicate the change of the current cipher and hmac
on the channel. Client can safely ignore the <cipher> argument
(if it chooses to do so) since the CHANNEL_KEY packet will
force the channel key change anyway. The <hmac> argument is
important since the client is responsible of setting the new
HMAC and the hmac key into use.
* Fixed the CMODE command in the client library as well.
* Tested CMODE command in router environment successfully.
Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Show the version of the remote client (or server) when connecting
to the server. It is logged to the log file. Affected file
is silcd/protocol.c.
* Fixed the KILLED notify handling in the client library. The
client must be removed from all channels when receiving the
KILLED notify.
Also, do not remove the client entry when giving the KILL
command but when the KILLED notify is received.
* Removed silc_idlist_find_client_by_nickname from the server.
Not needed anymore. Affected files silcd/idlist.[ch].
* Implemented the CHANNEL_CHANGE notify type handling to the
server. Affected file silcd/server.c.
* Updated TODO.
Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added silc_server_send_notify_invite to send the INVITE
notify between routers.
* Implemented the INVITE command correctly to the server.
* Implemented the INVITE notify type handling in the server.
* Implemented the INVITE command to the client library and on the
user interface.
Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added function silc_server_get_client_resolve to find the
client entry by ID from all ID lists and then resolve it
(using WHOIS) if it cannot be found. Affected file is
silcd/server.[ch].
Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Implemented the BAN command to the client library.
* The JOIN command in the server now checks the invite list
and the ban list.
* Changed the silc_command_reply_payload_encode_va and the
silc_command_payload_encode_va to support that if argument is
NULL it ignores and checks the next argument. Affected file
lib/silccore/silccommand.c.
* Added silc_server_send_notify_ban to send the BAN notify
type between routers.
* Chaned the silc_notify_payload_encode to support that if
argument is NULL it ignores and checks the next argument.
Affected file lib/silccore/silcnotify.c.
* Tested ban lists in router environment successfully.
Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Implemented BAN command to the server, in silcd/command.[ch].
* Removed the BAN and INVITE_LIST modes from the CMODE command
in the server code.

Affected files lib/silcutil/silcutil.[ch].
Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Redefined parts of the SilcChannelEntry in the server to support
the new ban and invite lists.
Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Redefined the INVITE command. The same command can be used to
invite individuals to the channel but also to manage the invite
list of the channel (to add to and remove from the invite list).
Updated the protocol specs.
* Added new command SILC_COMMAND_BAN that can be used to manage
the ban list of the channel. Updated the protocol specs.
* Removed the channel modes: the SILC_CMODE_BAN and the
SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
in the CMODE command. The equivalent features are now available
using INVITE and BAN commands. Updated the protocol specs.
* Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
in the network about change in the current ban list. The notify
type is not used by the client.
* Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
support the invite lists.
Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added new function silc_string_regexify that converts string
including wildcard characters into regex string that can
be used by the GNU regex library. Added into the file
lib/silcutil/silcutil.[ch].
Added silc_string_regex_combine to combine to regex strings
into one so that they can be used as one regex string by
the GNU regex library. Added into the file
lib/silcutil/silcutil.[ch].

TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Imported GNU regex to the soruce tree into lib/contrib.
Fixed some compiler warning from the regex.c.
Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed MOTD command in the server to work in router environment.
* Fixed the MOTD command in the client library to support
the server argument in the command.
* Added `nickname_len' argument to the silc_idlist_add_client
in the server, as the `nickname' argument may be binary data
(it may be hash).
* Added silc_idlist_get_channels to return all channels from
the ID list.
* Implemented LIST command to the server. Affected file is
silcd/command.c.
* Implemented the LIST command to the client library and on the
user interface.
* Added [<user count>] argument to the LIST command reply.
With private channels the user count is not shown.
* Updated TODO and README.
Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* The client entry's data.registered must be TRUE even with
global client entry on global client list. The data.registered
is used to check whether the client is anymore in the network,
for example with WHOWAS command so it must be valid.
* Fixed the WHOWAS command in the server. It now actually works
in router environment. Added function into silcd/command_reply.c
silc_server_command_reply_whowas_save.
* Added silc_idlist_purge function to the silcd/idlist.c
to periodically purge the ID Cache.
* Fixed INFO command in the server. It works now in router
environment. Added <server name> argument to the INFO command
reply. Updated the protocol specs.
* Fixed minor bug in silc_idcache_purge to not purge if the
expire value is zero.
* Fixed various bugs in WHOIS and IDENTIFY command handling as
they were buggy because of the WHOWAS information.
* Fixed local command MSG to handle the async resolving of
the remote client properly. It used to fail the first MSG.
Affected file silc/local_command.c.
* Added `data_len' field to SilcIDCache context.
Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Update TODO. Todo in commands in the server.
Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
used by routers as broadcast packet to inform other routers
about the changed user mode.
Implemented the notify handling in the server. Affected file is
silcd/packet_receive.c. Added the function
silc_server_send_notify_umode to the silcd/packet_send.[ch].
* Added new generic Channel Payload and deprecated the New Channel
Payload. The New Channel Payload is now the generic Channel
Payload.
* Added new argument `mode' to the silc_server_send_new_channel
as it is required in the Channel Payload now.
* Renamed the SilcChannelPayload to SilcChannelMessagePayload
and created a new and real SilChannelPayload to represent the
new generic Channel Payload. Implemented the encode/decode
for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
* Added silc_server_get_client_channel_list to return the list
of channels the client has joined for WHOIS command reply.
Affected file silcd/server.[ch].
* Implemented the channel list sending in the WHOIS command reply
in server and in the client.
Implemented the channel list displaying on the user interface
as well. Affected file silc/client_ops.c.
* Added silc_channel_payload_parse_list to parse list of Channel
Payloads. It returns SilcDList list of SilcChannelPayloads.
Client for example can use this function to parse the list of
channels it receives in the WHOIS command reply. The caller
must free the list by calling silc_channel_payload_list_free.
Affected files lib/silccore/silcchannel.[ch].
Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added one new argument <user mode> to the WHOIS command reply
to return the mode of the user in SILC. Updated the protocol
specs.
Implemented it to the server and client.
Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed the mode printing on the user interface on joining.
Affected file silc/client_ops.c.
* Implemented the UMODE command and user modes in general to the
client library and to the user interface.
* Implemented the UMODE command to the server.
* The server now sends UNKNOWN_COMMAND error status if client sends
unknown command. Affected file silcd/command.c.
* All server commands now handle the command identifier the right
way when sending the command reply to the client. The client can
use to identify the command replies with the identifier.
Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added silc_server_get_client_route to resolve the route to
the client indicated by the client ID. Affected file is
silcd/server.[ch].
* Added silc_server_relay_packet as general function to relay
packet to arbitrary destination. This deprecates functions
like _send_private_message_key, _relay_notify etc. Affected
file is silcd/packet_send.[ch].
Removed silc_server_send_key_agreement,
silc_server_send_private_message_key and
silc_server_packet_relay_notify functions from the file
silcd/packet_send.[ch].
* Updated TODO.
* Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
server. Affected file silcd/packet_receive.[ch].
* Implemented the KILL command to the client. Implemented the
SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
Affected files lib/silcclient/command[_reply].c and
lib/silcclient/client_notify.c. Implemented the KILL notify
printing in the user inteface.
* Fixed a lot silc_parse_nick memory leaks from the client
library in the file lib/silcclient/command.c.
* Changed the silc_server_send_notify_on_channels's `sender'
argument from SilcSocketConnection to SilcClientEntry to
check the sender as entry and not as connection object and not
to send to the client provided as argument. The affected file
is silcd/packet_send.[ch].
* The notify packets that are destined directly to the client used
to not to be processed by the server. Now changed that and the
server processes all notify packets. After relaying the packet
to the client the notify packet is processed in the server.
* The silc_server_free_client_data now checks whether there is
pending outgoing traffic for the client and purges the data to
the network before removing the client entry.
Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
an client is killed from the SILC Network. Updated the protocol
specs accordingly.
Added new function silc_server_send_notify_killed to the
silcd/packet_send.[ch].
* Added function silc_server_packet_relay_notify to relay notify
packets that are destined directly to a client. In this case
the server does not process the notify packets but merely relays
it to the client. Affected file silcd/packet_send.[ch].
Added also silc_server_packet_process_relay_notify to check
whereto relay the notify. Affected file is
silcd/packet_receive.[ch].
* Implemented the KILL command to the server.
* Updated TODO.
* Added the backup schema desgined last fall to the protocol
specs for everyone to see. The specification is in the
*-spec-xx.txt draft and the packet type definitions for the
backup routers is in *-pp-xx.txt draft. Thusly, added also
new packet type SILC_PACKET_CELL_ROUTERS.
* A big security problem in the implementation discovered. The
signoff of an client did not cause new channel key generation
which it of course should've done. The channel keys must be
always re-generated when client leaves (or signoffs) the channel.
The silc_server_remove_from_channels funtion now handles
the channel key re-generation.
* Added `sender' argument to the silc_server_send_notify_on_channels
to not to send the client provided as argument. Affected file
silcd/packet_send.[ch].
Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Implemented OPER and SILCOPER commands into the server and
the client library.
* Added silc_auth_verify and silc_auth_verify_data to verify
the authentication directly from the authentication payload.
It supports verifying both passphrase and public key based
authentication. Affected file lib/silccore/silcauth.[ch].
* Added `hash' field to the SilcIDListData structure. It is the
hash negotiated in the SKE protocol. Affected file is
silcd/idlist.[ch].
* Slight redesigning of the SilcAuthPayload handling routines.
Do not send SilcPKCS but SilcPublicKey as argument.
* Implemented the public key authentication support to the
serverconfig. The public key is loaded from the provided path
and saved as authentication data to void * pointer. Thus,
changed the unsigned char *auth_data to void *auth_data;
* Fixed SHUTDOWN command to send the reply before the server
is shutdown. :) Affected file silcd/command.c.
* Fixed fatal bug in CONNECT command. The hostname was invalid
memory and server crashed. Affected file silcd/command.c.
* Fixed fatal bug in CLOSE command. The server_entry became
invalid but was referenced later in the command. Affected file
silcd/command.c.
Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed fatal bug in failure packet handling. Server ignored
the failure and thus crashed when it came.
* Updated TODO.
Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added new SILC_CF_LAG_STRICT command flag that strictly forces
that the command may be executed only once in (about) 2 seconds.
The old SILC_CF_LAG flag is same but allows command bursts up
to five before limiting.
Added the support for CF_LAG and CF_LAG_STRICT flags to the
server code. Various commands now includes the CF_LAG_STRICT
flag to disallow any kind of miss-use of the command.
* Fixed the silc_buffer_unformat to not to allocate any data
if the length of the data is zero. It used to allocate the
length + 1. Affected file lib/silcutil/silcbuffmt.c.
Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Changed the format of AdminConnection configuration section
in the server. Added username of the admin to the format.
Affected files silcd/serverconfig.[ch].
Added silc_server_config_find_admin into silcd/serverconfig.[ch]
to return admin configuration data by host, username and/or
nickname.
Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Implemented WHOWAS command to the server. Added the functions:
silc_server_command_whowas_parse,
silc_server_command_whowas_send_reply,
silc_server_command_whowas_from_client and
silc_server_command_whowas_from_server
* Added <Client ID> argument to the WHOWAS command reply. Updated
the protocol specs accordingly.
* Implemented WHOWAS command and command_reply to the client
library.
Implemented the WHOWAS printing on the user interface.
Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added new argument to the WHOWAS command reply, the real name.
It is an optional argument. Updated the protocol specs.
* Added SilcIDCacheDestructor callback that is registered when
the SilcIDCache is allocated. The callback is called when
an cache entry in the ID Cache expires, or is purged from the
cache. Added into lib/silccore/idcache.[ch].
Added silc_idlist_client_destructor to the silcd/idlist.[ch]
to destruct the client entries when the cache entry expires.
Other ID Cache's in server and in the client library ignores
the destructor.
* If the ID Cache entry's `expire' field is zero then the entry
never expires. Added boolean `expire' argument to the
silc_idcache_add function in the lib/silccore/idcache.[ch].
If it is TRUE the default expiry value is used.
* Added silc_server_free_client_data_timeout that is registered
when client disconnects. By default for 5 minutes we preserve
the client entry for history - for WHOWAS command.
Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added support to the server to enforce that commands are not
executed more than once in 2 seconds. If server receives
commands from client more frequently, timeout is registered
to process the commands. Affected file silcd/command.c.
Added new function silc_server_command_process_timeout.
* Changed NICK_NOTIFY handling in client library to check that
if the client's nickname was changed, so there is no need to
resolve anything from the server.
* Removed error printing from the WHOIS and IDENTIFY commands.
If error occurs then it is ignored silently in the client library.
The application, however, may map the received error to
human readable error string. The application currently maps
the NO_SUCH_NICKNAME error to string.
* Made the command status message public to the application. Moved
them from lib/silcclient/command_reply.c to
lib/silcclient/command_reply.h. The application can map the
received command status to the string with the
silc_client_command_status_message function.
* Added check to the server to check that client's ID is same
as the Source ID in the packet the client sent. They must
match.
Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added dist-bzip hook to the Makefile.am to make bzip2
compressed distributions.
Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Server now enforces the maximum length for the nickname and
the channel as protocol specification dictates. 128 bytes for
nickname and 256 bytes for channel name.
* Moved the WHOIS printing to the application. The client libary
does not print out the WHOIS information anymore, the application
must do it. Renamed silc_client_command_reply_whois_print to
the silc_client_command_reply_whois_save.
The client's idle time is also sent to the application now, and
the idle is shown on screen.
* Added silc_client_command_reply_identify_save to save the
received IDENTIFY entries.
* Do not check for channel private keys in message sending and
reception if the channel does not have the PRIVKEY mode set.
Affected file lib/silclient/client_channel.c.
Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed a minor bug if WHOIS and IDENTIFY command parsing that
just surfaced after chaning the JOIN procedure.
Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added silc_client_get_clients_by_list to get client entries
from Client ID list, that is returned for example by JOIN
and USERS command replies. The application should use this
function for example when JOIN command reply is received to
resolve the clients already on the channel (library does not
do that anymore as USERS command reply is not used in the JOIN
procedure anymore). Affected files lib/silcclient/silcapi.h and
lib/silcclient/idlist.c.
* JOIN command reply and USERS command reply returns now SilcBuffer
pointers instead of unsigned char pointers when returning
the client list and mode list.
* Added <Client ID> argument to the JOIN command reply, mainly
for the server to identify for which client the command was
originally sent. Updated protocol specs accordingly.
* Added SilcDlist private_key pointer to the SilcChannelEntry
in the client to support the channel private keys. Affected
file is lib/silcclient/idlist.h.
* Added SilcChannelPrivateKey argument to the function
silc_client_send_channel_message so that application can choose
to use specific private ke if it wants to. If it is not provided,
the normal channel key is used, unless private keys are set.
In this case the first (key that was added first) is used
as the encryption key.
* Implemented the support for channel private key handling.
Implemented the following functions:
silc_client_add_channel_private_key,
silc_client_del_channel_private_keys,
silc_client_del_channel_private_key,
silc_client_list_channel_private_keys and
silc_client_free_channel_private_keys
Affected file lib/silcclient/client_channel.c.
* Added the support for the private keys in the channel message
sending and encryption and in the message reception and
decryption. Affected funtions are
silc_client_send_channel_message and silc_client_channel_message.
Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added SKE's key verify callback to the client library's
KE protocol context. Affected files lib/silcclient/protocol.[ch].
* Removed the statement that server (or router) must send USERS
command reply when joining to the channel so that the client
knows who are on the channel. Instead, the client list and
client's mode list is now sent in the JOIN command reply to the
client who joined channel. This is better solution.
* Added function silc_server_get_users_on_channel and function
silc_server_save_users_on_channel to the silcd/server.[ch].
* Removed function silc_server_command_send_users from the
silcd/command.c.
* Do not show topic on the client library anymore. The topic is
sent in the command reply notify to the application and the
application must show the topic now.
Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added client searching by nickname hash into the IDENTIFY and
WHOIS commands in the server as they were clearly missing from
them. Affected file is silcd/command.c.
* Fixed a bug in private message receiving in the client library.
The remote ID was freed and it wasn't supposed, now it is
duplicated.
Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Minor fix to the channel payload; allocate the data area, as it
needs to be of specific length.
* If the key agreement port is zero then the operating
system will define the bound port. Affected files are
lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
* Added new function silc_channel_payload_decrypt into the file
lib/silccore/silcchannel.[ch].
* Moved the channel message etc, check from silc_packet_decrypt
to applications. The library calls now a generic
SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
when the packet is either normal or special. This was done to
allow more wide range of checking that was not allowed when
the code was in library. Now applications can do virtually any
checks to the packet and return to the library the decision how
the packet should be processed. Affected files are
lib/silccore/silcpacket.[ch].
Added silc_server_packet_decrypt_check to the server and
silc_client_packet_decrypt_check to the client library.
* Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
to send with specified source and destination information.
* Channel message delivery between routers was broken after the
channel key distribution was fixed earlier. The channel key
was used be to distributed to other routers as well which is not
allowed by the protocol. Now this is fixed and channel keys
really are cell specific and the channel message delivery between
routers comply with the protocol specification.
* Fixed various commands in server to check also the global list
for the channel entry and not just the local list. The affected
file silcd/command.c.
Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added assert()s to buffer formatting and unformatting routines
to assert (if --enable-debug) when error occurs. Affected
file: lib/silcutil/silcbuffmt.c.
* Changed to auto-reconnect to check whether the remote host is
router and register the re-connect timeout if it is. It used
to check that whether we are normal server, but router must do
auto-reconnect with another router as well. Affected file
silcd/server.c.
* Removed the [<key len>] option from CMODE command as the cipher
name decides the key length, nowadays. See the defined ciphers
from the protocol specification.
* Added [<hmac>] option to the CMODE command to define the HMAC
for the channel. Added SILC_CMODE_HMAC channel mode.
* Added [<hmac>] option for the JOIN command so that user can
select which HMAC is used to compute the MACs of the channel
messages.
* Added Hmac field to the Channel Message Payload. The integrity
of plaintext channel messages are now protected by computing
MAC of the message and attaching the MAC to the payload. The
MAC is encrypted. Now, it is clear that this causes some
overhead to the size of the packet but rationale for this is that
now the receiver can verify whether the channel message decrypted
correctly and also when private keys are set for the channel the
receiver can decrypt the packet with several keys and check from
the MAC which key decrypted the message correctly.
* Added silc_cipher_encrypt and silc_cipher_decrypt into the
lib/silccrypt/silccipher.[ch].
* Added silc_hash_len to return the digest length into the
lib/silcrypt/silchash.[ch].
* Rewrote parts of Silc Channel Payload interface in the
lib/silccore/silcchannel.[ch]. The encode function now also
encrypts the packet and parse function decrypts it.
Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed a minor formatting bug in the SKE's key material processing.
It actually might have processed the keys wrong way resulting
into wrong keys.
* Redefined the mandatory HMAC algorithms and added new algorithms.
Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
and hmac-md5 truncated to 96 bits. The mandatory is now
hmac-sha1-96. Rest are optional (including the one that used
to be mandatory). Rationale for this is that the truncated HMAC
length is sufficient from security point of view and can actually
make the attack against the HMAC harder. Also, the truncated
HMAC causes less overhead to the packets. See the RFC2104 for
more information.
* Added new [hmac] configuration section. The SKE used to use
the hash names (md5 and sha1) in the SKE proposal as HMCAS which
is of course wrong. The official names that must be proposed in
the SKE are the ones defined in the protocol specification
(hmac-sha1-96 for example). The user can configure any hmac
using any hash function configured in the [hash] section. At
least, the mandatory must be configured.
Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
* Added HMAC list to the SKE proposal list. It has now both
hash algorithm list and HMAC list. This makes the protocol
incompatible with previous versions. The SKE now seems to work
the way it is supposed to work, for the first time actually.
* Defined plain Hash algorithms to the protocol specification.
Added sha1 and md5.
Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Implemented support for key agreement packets into the server.
Added functions silc_server_key_agreement and
silc_server_send_key_agreement. Other than these functions,
server has nothing to do with this packet.
* Added support for private message key packets into the server.
Added functions silc_server_private_message_key and
silc_server_send_private_message_key.
* Updated TODO.
* Changed the silc_[client|server]_protocol_ke_set_keys to be
called in the protocol's final callback instead in the END
protocol state. This makes a little more sense and in the same
time in client we can use the same protocol routines for normal
key exchange and to key agreement packet handling as well.
* Added to both client's and server's KE protocol context the
SilcSKEKeyMaterial pointer to save the key material. We will
bring the key material to the protocol's final callback by doing
this. The final callback must free the key material.
* Added SKE's packet_send callback into client's KE protocol
context so that the caller can choose what packet sending function
is used. This way we can use different packet sending when
doing normal SKE when doing key agreement packet handling (in
the key agreement packet handling we do not want to encrypt
the packets).
* Implemented the responder side of the key agreement routines
in the client. The client can now bind to specified port and
accept incoming key negotiation. The key material is passed
to the application after the protocol is over.
* Implemented the processing of incoming Key Agreement packet
in the client. Added function silc_client_key_agreement to
process the packet.
* Implemented the intiator side of the key agreement routines
in the client. The client can now initiate key agreement with
another remote client. The key material is passed to the
application after the protocol is over.
* Created client_keyagr.c to include all the key agreement
routines.
* Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
SILC_TASK_CALLBACK except that it is not static.
* Created client_notify.c and moved the Notify packet handling
from the client.[ch] into that file.
* Created client_prvmsg.c and moved all private message and
private message key routines from the client.[ch] into that file.
* Create client_channel.c and moved all channel message and
channel private key routines from the client.[ch] into that file.
* Changed silc_client_get_client_by_id_resolve to resolve with
WHOIS command instead of IDENTIFY command, in the file
lib/silclient/idlist.c.
Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Implemented the SKE's responder side to the Client library.
* When FAILURE is received to the protocol do not trust it
blindly. Register a timeout to wait whether the remote closes
the connection as it should do it, only after that process the
actual failure. This was changed to both client and server.
* Added client_internal.h to include some of the structures
there instead of client.h in lib/silcclient/.
* Added function silc_task_unregister_by_callback to unregister
timeouts by the callback function.
Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Some "Incomplete WHOIS info" errors has been appearing on the
log files. Took away the entry->userinfo check from WHOIS
reply sending. The entry->userinfo is now " " if client did not
provide one. I thought this was fixed earlier but something
is wrong still. Let's see if the error still appears.
Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed a minor bug in the login when the channel key is
re-generated in the server. It used to generate the key in
wrong order and thus caused problems in the channel traffic.
* Fixed a minor bug in channel key distsribution after
KICK command. The key was not sent to the router even though
it should've been.
Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added silc_ske_process_key_material_data as generic routine
to process any key material as the SILC protocol dictates. The
function is used by the actual SKE library but can be used by
applications as well. This relates to the private message keys
and the channel private keys since they must be processed the
same way the normal SILC session keys. The protocol dictates
this. Affected files: lib/silcske/silcske.[ch].
Added also silc_ske_free_key_material to free the
SilcSKEKeyMaterial structure.
* Defined silc_cipher_set_key function to set the key for
cipher without using the object's method function. The affected
files: lib/silccrypt/silccipher.[ch].
* Implemented silc silc_client_add_private_message_key,
silc_client_add_private_message_key_ske,
silc_client_del_private_message_key,
silc_client_list_private_message_keys and
silc_client_free_private_message_keys functions in the
client library.
Added functions silc_client_send_private_message_key to send
the Private Message Key payload and silc_client_private_message_key
to handle incoming Private Message Key payload.
* Added Cipher field to the Private Message Key payload to set
the cipher to be used. If ignored, the default cipher defined
in the SILC protocol (aes-256-cbc) is used.
Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Removed lib/silcclient/ops.h file.
Redefined parts of the SILC Client Library API. Created new
file silcapi.h that deprecates the ops.h file and defines the
published Client Library API. Defined also private message key
API and channel private key API into the file.
This is the file that the application must include from the
SILC Client Library. Other files need not be included by
the application anymore.
* Added new key_agreement client operation callback and also
defined the Key Agreement library API for the application.
Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
is used by clients to request key negotiation between another
client in the SILC network. If the negotiation is started it
is performed using the SKE protocol. The result of the
negotiation, the secret key material, can be used for example
as private message key.
Implemented the Key Agreement payload into the files
lib/silccore/silauth.[ch].
Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Redefined ciphers for the SILC protocol. Added some new ciphers
and defined the key lengths for the algorithms. Changed the
code accordingly. The default key length is now 256 bits.
* Fixed SKE key distribution function silc_ske_process_key_material
when the key length is more than 128 bits. The default key
length in SILC is now 256 bits.
* Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
to indicate unsupported algorithm.
* Renamed rijndael.c to aes.c and all functions as well.
* Fixed a long standing channel key setting bug in client library.
Weird that it has never surfaced before.
* Fixed bug in channel deletion. If the entire channel is removed
then it must also delete the references of the channel entry
from the client's channel list as the client's channel entry and
the channel's client entry share same memory.
Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Implemented CONNECT and SHUTDOWN commands in the client.
* Implemented CLOSE command to the client.
* Added the function silc_idlist_find_server_by_name into the
files silcd/idlist.[ch].
Added the function silc_idlist_find_server_by_conn into the
files silcd/idlist.[ch].
Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* DIE command was renamed to SHUTDOWN. Updated the both code
and protocol specs.
* Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
* Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
side.
* Added function silc_server_create_connection function to create
connection to remote router. My server implementation actually
does not allow router to connect to normal server (it expects
that normal server always initiates the connection to the router)
so the CONNECT command is only good for connecting to another
router.
Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
or some other client was kicked from the channel.
Implemented the handling of the notify type to both client
and server.
Implemented silc_server_send_notify_kicked to send the KICKED
notify. It is used to send it to the server's primary router.
* Implemented the KICK command into server and client.
* Added `query' argument to the silc_idlist_get_client function
to indicate whether to query the client from server or not if
it was not found.
* Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
to indicate that the client is not channel founder.
* Updated TODO.
Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Removed the rng context from SilcPacketContext structure and
changed that the packet routine uses the Global RNG API.
Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added support for quit message that client can "leave" on the
channel when it quits the SILC. It is ditributed inside the
SILC_NOTIFY_TYPE_SIGNOFF notify type.
Added silc_server_free_client_data that will take the
signoff message as argument.
* Changed SKE routines to use the silc_pkcs_sign/verify routines.
Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Updated parts of the protocol specification to keep it up
to date.
Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
payloads in one packet.
* Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
use now the new List flag.
* Also deprecated the following packet types: REPLACE_ID,
NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
* Added list support for Notify packet in server.
* Added silc_server_send_notify_channel_change to send the
CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
the silc_server_send_replace_id.
* Added silc_server_send_notify_nick_change to send the
NICK_CHANGE notify type. Deprecates the function
silc_server_send_replace_id.
* Added silc_server_send_notify_join to send the JOIN notify type.
Deprecates the function silc_server_send_new_channel_user.
* Added silc_server_send_notify_leave to send LEAVE notify type.
Deprecates the function silc_server_send_remove_channel_user.
* Added silc_server_send_notify_cmode and
silc_server_send_notify_cumode to send CMODE and CUMODE notify
types. Deprecates the silc_server_send_set_mode function.
* Added SERVER_SIGNOFF notify type to indicate that server has
quit. This means that all clients on the channel from that
server will drop. This can be also used when netsplit happens.
Deprecated REMOVE_ID packet type since it is not needed anymore
even from server.
Added silc_server_send_notify_server_signoff to send the
SERVER_SIGNOFF notify type. Deprecates the function
silc_server_send_remove_id.
Added also silc_server_send_notify_signoff to send the
SIGNOFF notify type.
* Employed the PKCS #1. It is the mandatory way to do RSA in the
SILC protocol from this day on. Changed the protocol
specification as well.
* Added silc_server_send_notify_topic_set to send TOPIC_SET
notify type. It is used between routers to notify about
topic changes on a channel.
* Added silc_id_dup into lib/silccore/id.[ch] to duplicate
ID data.
* Partly updated the protocol specification to comply with the
changes now made. It is still though a bit outdated.
* The JOIN notify type now takes one extra argument <Channel ID>.
The packet used to be destined to the channel but now the
JOIN type may be sent as list thus it is impossible to
destine it to any specific channel. By adding this argument
it is again possible.
Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added CREDITS file. The CHANGES and CREDITS file will appear
in the distribution as well.
Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
types in the server's silcd/packet_receive.c.
* Implemented CMODE and CUMODE to work in router environment.
* Fixed minor encoding and decoding buglet from the
lib/silccore/silcmode.c.
* Fixed buffer overflow from lib/silcclient/command.c in USERS
command parsing.
Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
* Changed all SilcConfigServer* and silc_config_server* to
SilcServerConfig* and silc_server_config*, respectively.
Patch by Bostik.
Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Associated the ID (client or server ID) to the Authentication
Payload to avoid any possibility of forging. Updated the
protocol specification and the code accordingly.
Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* The RSA key length is now save to the RsaKey context in the
key generation process in lib/silccrypt/rsa.c. The key length
is now used to figure out the maximum size of the block allowed
to be encrypted/signed.
* Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
is equivalent to the silc_mp_mp2bin but does not allocate any
memory.
* Changed silc_mp_mp2bin API to take length argument. If it is
non-zero then the buffer is allocated that large. If zero, then
the size is approximated using silc_mp_sizeinbase, which however
is not relieable.
* Created Global RNG API which is global RNG that application can
initialize. After initializing, any routine anywhere in the
code (including library) can use RNG without allocating a new
RNG object. This was done to allow this sort of use of the
RNG in code that has no chance to allocate RNG object. All
applications currently allocate this and many routines in the
library use this. Affected file lib/silccrypt/silcrng.[ch].
* Removed the RNG kludge from lib/silcmath/primegen.c and changed
it to use the Global RNG API.
* Defined Authentication Payload into protocol specification that
is used during SILC session to authenticate entities. It is
used for example by client to authenticate itself to the server
to obtain server operator privileges.
Implemented this payload into the lib/silccore/silcauth.[ch].
Implemented also routines for public key based authentication
as the new protocol specification dictates.
Moved definitions of different authentication methods from
lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
* Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
silc_pkcs_verify and silc_pkcs_sign_with_hash and
silc_pkcs_verify_with_hash functions into the file
lib/silccrypt/silcpkcs.[ch].
Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* The client entry's userinfo pointer must be always valid.
Otherwise the [<unknown>] bug will surface beacuse the WHOIS
will fail since it requires the userinfo. Now, the userinfo
is allocated as "" if actual userinfo does not exist. Actually,
it must exist and it is totally Ok to drop client connections
that does not announce the userinfo. However, we will make
this workaround for now.
* Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
to return the remote port by socket.
Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
SILC_SERVER_PENDING_EXEC and added an new macro
SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
data or when error occurs while processing the pending command.
Added new argument `destructor' into silc_server_command_pending
and to the SilcServerCommandPending object. This destructor is
now called after calling the pending callback or if error occurs
immediately. If error occurs the actual pending callback won't
be called at all - only the destructor. The destructor may be
NULL if destructor is not needed.
All this applies for client library code as well. Similar
changes were made there as well for the pending commands.
In the client, the application must now allocate the
SilcClientCommandContext with the silc_client_command_alloc
function.
* Added reference counter to the SilcServerCommandContext. Added
function silc_server_command_alloc and silc_server_command_dup
functions.
Same type of functions added to the client library for the same
purpose as well.
* Removed the cmd_ident from IDListData away since it is now
global for all connections. It is the command identifier used
in command sending and with pending commands. The affected file
is silcd/idlist.h.
* Added reference counter to the SilcSocketConnection objecet to
indicate the usage count of the object. The object won't be
freed untill the reference counter hits zero. Currently only
server uses this, and client ignores it. The client must be
set to use this too later. The affected files are
lib/silccore/silcsockconn.[ch]. Added also the function
silc_socket_dup to increase the reference counter.
This was mainly added because it is possible that the socket
is removed underneath of pending command or other async
operation. Now it won't be free'd and proper DISCONNECTING
flags, etc. can be set to avoid sending data to connection that
is not valid anymore.
* Added SILC_SET_DISCONNECTING to server.c when EOF is read from
the connection. After that it sets SILC_SET_DISCONNECTED.
It is, however, possible that the socket data is not still freed.
The silc_server_packet_process now checks that data is not
read or written to connection that is DISCONNECTED. The socket
get's freed when the reference counter hits zero.
Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Changed the client operation API: channel_message operation's
`sender' is now the client entry of the sender, not the nickname
and the `channel' is the channel entry, not the channel name.
In the private_message operation the `sender' is now also the
client entry of the sender not the nickname.
Affected file is lib/silcclient/ops.h and all applications
using the client operations.
Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Moved the calling of ops->connect() from connect_to_server_final
into receive_new_id functin since that is the point when the
client is actually allowed to send traffic to network. The
affected file is lib/silcclient/client.c.
Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
(if needs broadcasting) instead of broadcasting the packets one
by one which would make a burst in the network traffic.
* Added `broadcast' argument to the functions in silcd/server.[ch]
silc_server_create_new_channel[_with_id] to indicate whether
to send New Channel packet to primary router.
Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added new function into the silcd/server.[ch] files:
silc_server_create_new_channel_with_id to create new channel with
already existing Channel ID.
* Added new packet type SILC_PACKET_SET_MODE_LIST into the file
lib/silccore/silcpacket.h. This packet is used t send list of
Set Mode payloads inside one packet. Server uses this to set
the modes for the channels and clients on those channels, that it
announced to the router when it connected to it. The protocol
specification has been updated accordingly.
* The silc_server_new_channel did not handle the packet coming
from normal server as it normally does not send that. However,
when it announces its channels it does send it. Implemented
the support for that.
* Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
into the file lib/silccore/id.h.
Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed memory leaks in the functions silc_idlist_del_client,
silc_idlist_del_channel and silc_idlist_del_server in the file
silcd/idlist.c. All of those leaked like a sieve.
* Fixed some small memory leaks in the client's function
silc_client_notify_by_server.
* Added functions into silcd/server.c: silc_server_announce_clients,
silc_server_announce_channels and silc_server_announce_server.
These functions are used by normal and router server to announce
to its primary router about clients, channels and servers (when
router) that we own. This is done after we've connected to the
router.
These functions effectively implements the following packet types:
SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
and SILC_PACKET_NEW_ID_LIST.
* Added new functions into the silcd/packet_receive.[ch]:
silc_server_new_id_list, silc_server_new_channel_list and
silc_server_new_channel_user_list to handle the incoming
NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
* Added support of changing Channel ID in the function
silc_server_replace_id. If the server that announces a channel
to the router already exists in the router (with same name but
with different Channel ID), router is responsible to send
Replace ID packet to the server and force the server to change
the Channel ID to the one router has.
* Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
client that the Channel ID has been changed by the router. The
normal server sends this to the client. Client must start using
the new Channel ID as the channel's ID.
Implemented handling of this new type into lib/silcclient/client.c
into the function silc_client_notify_by_server.
* Added new function silc_idlist_replace_channel_id into the files
silcd/idlist.[ch] to replace the Channel ID.
Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Call silc_server_command_identify_check always when processing
the IDENTIFY command in silcd/command.c
Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added new packet type SILC_PACKET_HEARTBEAT that is used to
send keepalive packets. The packet can be sent by clients,
servers and routers.
Added function silc_socket_set_heartbeat into the file
lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
If not set, the heartbeat is not performed. The actual
heartbeat is implemented in the low level socket connection
library. However, application is responsible of actually
sending the packet.
Added silc_server_send_heartbeat to send the actual heartbeat
packet into silcd/packet_send.[ch]. Server now performs
keepalive with all connections.
* Added silc_task_get_first function into lib/silcutil/silctask.c
to return the timeout task with shortest timeout. There was a bug
in task unregistration that caused problems. TODO has been
updated to include that task system must be rewritten.
* The client library will now resolve the client information when
receiving JOIN notify from server for client that we know but
have incomplete information.
* Rewrote parts of silc_server_remove_from_channels and
silc_server_remove_from_one_channel as they did not remove the
channel in some circumstances even though they should've.
* Encryption problem encountered in server:
The LEAVE command used to send the Channel Key packet to the
router immediately after generating it. However, the code
had earlier sent Remove Channel user packet but not immediately,
ie. it was put to queue. The order of packets in the router
was that Channel Key packet was first and Remove Channel User
packet was second, even though they were encrypted in the
reverse order. For this reason, MAC check failed. Now, this
is fixed by not sending the Channel Key packet immediately but
putting it to queue. However, this is more fundamental problem:
packets that are in queue should actually not be encrypted
because packets that are sent immediately gets encrypted
actually with wrong IV (and thus MAC check fails). So, packets
that are in queue should be encrypted when they are sent to
the wire and not when they put to the queue.
However, the problem is that the current system has not been
designed to work that way. Instead, the packet is encrypted
as soon as possible and left to the queue. The queue is then
just purged into wire. There won't be any fixes for this
any time soon. So, the current semantic for packet sending
is as follows:
o If you send packet to remote host and do not force the send
(the packet will be in queue) then all subsequent packets to the
same remote host must also be put to the queue. Only after the
queue has been purged is it safe again to force the packet
send immediately.
o If you send all packets immediately then it safe to send
any of subsequent packets through the queue, however, after
the first packet is put to queue then any subsequent packets
must also be put to the queue.
Follow these rules and everything works fine.
Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added new function silc_server_remove_clients_by_server to
remove all client entries from ID list when the server connection
is lost. In this case it is also important to invalidate all
client entires as they hold the invalid server entry. This
fixes fatal bug when server has lost connection and will reconnect
again.
Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Made some sanity checks to silc_server_daemonise like to check
whether the requested user and group actually exists.
* Added sanity check to SKE's silc_ske_responder_finish to check
that the public and private key actually is valid.
* Invalidate the client's nickname when receiving Replace ID
packet and the Client ID is being replaced. This means that the
server will query the nickname if someone needs it (client)
a bit later.
* Sort the ID Cache in client library when the ID Cache data
has changed (needs sorting).
* Do not allow for SILC client to create several connections to
several servers. The client does not support windows right now
and generating multiple connections causes weird behaviour.
Irssi-silc client does support windows and can handle several
connections without problems, see: www.irssi.org and SILC plugin.
* Fixed some places where client was added to the IDList. The
rule of thumb is following (in order to get everything right):
If the client is directly connected local client then the
`connection' argument must be set and `router' argument must be
NULL to silc_idlist_add_client function. If the client is not
directly connected client then the `router' argument must
bet set and the `connection' argument must be NULL to the
silc_idlist_add_client function.
* The funtion silc_server_packet_send_local_channel actually did
not check whether the client was locally connected or not. It
does that now. Fixed a bug related to LEAVE command.
* Fixed Remove Channel User payload parsing bug in server's
silcd/packet_receive.c. Fixed a bug related to LEAVE command.
* The server's silc_server_save_channel_key now checks also the
global ID list for the channel as it might not be in the local
list. Fixed a bug related to LEAVE command.
* Is this the end of the [<unknown>] buglet that has been lurking
around for a long time? A little for loop fix in server's
silc_server_command_whois_parse that is used by both IDENTIFY
and WHOIS command. At least, this was a clear bug and a cause
of one type of [<unknown>] buglet.
* WHOIS and IDENTIFY commands call the function
silc_server_command_[whois/identify]_check function even if
we are not router server.
Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added --with-gmp configuration option. If set the GMP
is always compiled in the SILC source tree. If not set then
it is checked whether the system has the GMP3 installed. If
it has then the GMP won't be compiled (the system's headers
and library is used), if it doesn't have it then the GMP is
compiled in the SILC source tree.
Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Changed RSA private exponent generation to what PKCS #1
suggests. We try to find the smallest possible d by doing
modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
not security fix but optimization.
Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added new config entry [Identity] to fork the server and run
it as specific user and group. A patch from Bostik.
* Imported Dotconf configuration library into lib/dotconf.
This will be used to create the SILC configuration files later.
It will appear in the distsribution after this commit.
Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* A big code auditing weekend happening. Auditing code for
obvious mistakes, bugs and errors. Also, removing any code
that is obsolete.
Removed files for being obsolete:
o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
inline in the file lib/silcutil/silcbuffer.h)
o lib/silcutil/silcbufutil.c (the header has inline versions)
Changed code to fix possible error conditions:
o The buffer formatting routines now check that the destination
buffer really has enough space to add the data. This applies for
both buffer formatting and unformatting
(lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
unformatting was changed to accomodate following rules:
XXX_*STRING_ALLOC will allocate space for the data into the pointer
sent to the function while XXX_*STRING will not allocate or copy
the data into the buffer. Instead it sets the pointer from the
buffer into the pointer sent as argument (XXX_*STRING used to
require that the pointer must be allocated already). This change
makes this whole thing a bit more consistent and more optimized
(note that the data returned in the unformatting with XXX_*STRING
must not be freed now). The routines return now -1 on error.
o Tried to find all code that use buffer_format and buffer_unformat
and added return value checking to prevent formatting and
especially unformatting errors and possible subsequent fatal
errors.
o Changed ske->x and ske->KEY to mallocated pointers in
lib/silcske/silcske.h. Fixed possible data and memory leak.
o Added return value checking to all *_parse* functions. Fixed
many memory leaks as well.
o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
so that buffer overflows would not happen. All code now also
checks the return value as it can fail.
Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added reconnection support to server if the normal server looses
its connection to the router (for example if router is rebooted).
The server performs normal reconnection strategy implemented
to the server. Affected file silcd/server.c.
Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added new packet type SILC_PACKET_SET_MODE that is used to
distribute the information about changed modes (for clients,
channels and clients channel modes) to all routers in the
network. Updated the protocol specification accordingly.
Added functions into silcd/packet_send.c and
silcd/packet_receive.c: silc_server_send_set_mode,
silc_server_set_mode.
Added new files silcmode.[ch] into lib/silccore that implements
the encoding and decoding of Set Mode Payload. Added new type
SilcSetModePayload. Moved the definitions of different modes
from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Oops, a little mistake in server's connection authentication
protocol. The protocol is not ended with FAILURE but with
SUCCESS if the authentication is Ok. :) Affected file is
silcd/protocol.c.
* Implemented NICK_CHANGE notify handling in server in the file
silcd/packet_receive.c The NICK_CHANGE notify is distributed to
the local clients on the channel. After the changing nickname
in router environment snhould work and the [<unknown>] nickname
should appear no more.
The silc_server_replace_id function that receives the Replace ID
payload now sends the NICK_CHANGE notify type also in the file
silcd/packet_receive.c
* Changed WHOIS and IDENTIFY command to support the maximum amount
of arguments defined in protocol specs (3328 arguments). This
fixed a bug that caused problems when there were more than three
users on a channel.
Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added extra parameter, command identifier, to the
silc_client_send_command so that explicit command identifier
can be defined.
Changed that ID list routines uses specific command identifier
when sending WHOIS/IDENTIFY requests to the server so that they
can be identified when the reply comes back.
Affected files lib/silcclient/command.[ch],
lib/silcclient/client.c and lib/silcclient/idlist.[ch].
* Added `sender' argument to silc_server_packet_send_to_channel
to indicaet the sender who originally sent the packet to us
that we are now re-sending. Ignored if NULL. Affected file
silcd/packet_send.[ch].
* Added some server statistics support in silcd/server_internal.h
SilcServerStatistics structure and around the server code. Also
send some nice statistics information when client is connecting
to the client.
Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed channel ID decoding in server's JOIN command reply in
silcd/command_reply.c
* Fixed braodcasting of replace ID payload to not to send it if
we are standalone server in silcd/packet_receive.c.
* Fixed all channel message sending routines to not to send
packets to clients that has router set, since they are routed
separately in the same function earlier. Affects file
silcd/packet_send.c and all channel packet sending functions.
* In USERS reply, res_argv[i] are not allocated, the table
is allocated. Thus changed that free the table, not its
internals.
* In server's whois_check and identify_check if the client is
locally connected do not send any WHOIS commands - they are not
needed.
Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed some minor bugs in client when sending WHOIS command. The
arguments was in wrong order.
* Removed statis function add_to_channel from server in
silcd/command.c that was previously used with the joining but
is obsolete now.
* Tested USERS command in router environment successfully with two
routers, two servers and two clients.
Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Reorganized the USERS command and command reply in client library
in lib/silcclient/command.c and lib/silcclient/command_reply.c.
When the command is given by user we register a pending command
callback that will reprocess the command after the reply has been
received from the server. When reprocessing the packet we then
display the information. Thus, the USERS information is displayed
now in the command callback instead of in the command reply
callback. The processing of the command is same as previously
when server has sent the command reply in the JOINing process.
* Added to USERS command in silcd/command_reply.c to join the client,
we didn't use to know about, to the channel after we've created
a client entry for it. Also, for clienet we did know already still
check whether it is on the channel or not and add it if not.
* Removed silc_server_command_join_notify as the function and its
use was obsolete.
Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Changed the client's pending command handling to the same as the
server's pending command handling. It is also now possible to
execute command reply functions from other command reply
function as the function callbacks for commands and command
replies are one and same. The pending commands are not static
list anymore, it is mallocated SilcDList in lib/silcclient/client.h
in client connection context. Thus, pending commands are server
connection specific as it is convenient.
Changed the function silc_client_command_pending and
silc_client_command_pending_del and added new function
silc_client_command_pending_check. Removed the
SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
macros.
* Added cmd_ident, current command identifier, to the client
connection context in lib/silcclient/client.h to keep track on
command identifiers used in command sending. Client's command reply
function handling now supports the mandatory command identifiers.
* Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
funtions in client to fully support pending command callbacks.
* NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
as one of the arguments to the application in the command reply
client operation.
* NOTE: The FORWARDED flag is depracated. It used to be depracated
before first releasing SILC but came back. Now it is removed again
and should come back nomore. The FORWARDED flag was used only
by the JOINing procedure by forwarding the command packet to router.
Now, the JOINing procedure has been changed to more generic (due
to various router environment issues) and FORWARDED is not needed
anymore for anything. The protocol specification is yet to be
updated.
Now, removed silc_server_packet_forward from server and the flag
SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Renamed NAMES command to USERS command. The NAMES was named that
due to historical reasons. Now it is renamed. Also, rewrote
parts of the USERS command. The nickname list is not sent anymore
by the server. Only Client ID and mode lists are sent in the USERS
command. Changed this also to the protocol specification.
The client now resolves the names and stuff after it receives
the USERS list from the server when joining to the channel.
* WHOIS and IDENTIFY commands has been changed to support multiple
Client ID's per command. One can now search for multiple users
in the network by sending only one WHOIS or IDENTIFY command.
Changed the code and the protocol specifications.
* Removed silc_server_command_identify_parse and changed that IDENTIFY
uses silc_server_command_whois_parse to parse the request. */
* If normal server, do not parse the WHOIS and IDENTIFY requests
before sending it to the router. Saves some time.
Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed JOIN command on client library. Wrong number of arguments
used to crash the client.
* Added silc_server_channel_has_global function to check whether
channel has global users or not.
* Added silc_server_channel_has_local function to check whether channel
has locally connected clients on the channel.
* The silc_server_remove_from_one_channel now checks whether the
channel has global users or not after given client was removed from
the channel. It also checks whether the channel has local clients
on the channel anymore. If it does not have then the channel entry
is removed as it is not needed anymore.
* The silc_server_notify now checks on JOIN notify whether the joining
client is one of locally connected or global. If it is global then
the channel has now global users on the channel and that is marked
to the channel entry. Also, it now saves the global client to
global list who is joining and JOINs it to the channel. This is
for normal server, that is.
Changed silc_server_send_notify_on_channel,
silc_server_packet_relay_to_channel and
silc_server_packet_send_to_channel check if we are normal server
and client has router set (ie. global client) do not send the
message to that client, as it is already routed to our router.
* Implemented LEAVE notify type handling in silc_server_notify
function.
* Tested LEAVE command in router environment successfully. Tested
with two routers, two servers and two clients.
* Updated TODO.
* idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
* Implemented SIGNOFF notify type handling in silc_server_notify
function.
* silc_server_remove_id now removes the client entry from all channels
it has joined and thusly sends SIGNOFF notify type.
* Rewrote the NAMES list generation in server by removing two excess
loops. The lists are created now inside one loop.
Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* silc_server_remove_channel_user checks now also global list
for channel and client.
* silc_server_new_channel_user checks now both local and global
list for channel and client. Fixed a bug in client id decoding.
Used to decode wrong buffer.
* silc_server_channel_message checks now both local and global
list for channel entry.
* Tested channel joining (hence JOIN) in router environment
successfully. Tested with two routers, two servers and two
clients.
* Tested channel message sending in router environment successfully.
Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added silc_server_save_channel_key into server.[ch] to save the
received channel key in Channel Key payload processing. It is
also used in JOIN command reply handling.
Equivalent function silc_client_save_channel_key added into
client.[ch] into client library.
* Changed JOIN command reply to send information whether the channel
was created or not (is existing already) and the channel key
payload. Changed protocol specs accordingly.
* Fixed bugs in WHOIS and IDENTIFY command reply sending when
the request was sent by ID and not by nickname. Crashed on
NULL dereference.
Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
now correctly save the received data.
* silc_server_free_sock_user_data now notifies routers in the
network about entities leaving the network.
At the same time implemented functions silc_server_remove_id
and silc_server_send_remove_id to receive and send REMOVE_ID
packets. The packet is used to notify routers in the network
about leaving entities. The ID removed will become invalid in
the network.
* Added function silc_idlist_del_server into server. Removes and
free's server entry from ID list.
* silc_server_private_message function now checks, if we are router,
that the destination ID really is valid ID, naturally.
* In router when NEW_ID packet is received (for new client) the
hash of the Client ID is saved in the ID Cache but the
client->nickname is set to NULL, instead of putting the hash
to it as well.
IDENTIFY command now also checks that client->nickname must be
valid. If it is not if will request the data from the server who
owns the client. Added new function
silc_server_command_identify_check.
* Added silc_command_set_command into lib/silccore/silcommand.[ch]
to set the command to already allocated Command Payload.
* Tested private message sending in router environment with two
routers, two servers and two clients. Fixed minor bugs and now
it works fine.
* Fixed segfault from client's NAMES command. Used to crash if
not on any channel.
* Forwarded packets must not be routed even if it is not destined
to the receiver. Changed server code comply with this.
Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added `require_reverse_mapping' boolean value to ServerParams
structure. If TRUE (not default) the server will require that
the connecting host has fully qualified domain name.
If the reverse mapping is not required and hostname could not be
found the IP address is used as hostname.
Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Implemented version string checking to both client and server.
The check is incomplete currently due to the abnormal version
strings used in development version of SILC.
* Changed all command functions in server to use the new
CHECK_ARGS macro.
Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Changed char *data to unsigned char *data in ID Cache system to
support binary data as ID Cache data. Changed code to support
binary data in lib/silccore/idcache.c.
* Renamed silc_server_packet_relay_command_reply to
silc_server_command_reply as it is normal packet receiving
function. Rewrote the function to accept command replys for
servers and not only for clients.
* Mark remote router always as registered server if we are connecting
to it. Otherwise, commands sent by the router to us are ignored.
* All ID List find routines now returns the ID Cache Entry pointer
as well if requested.
* WHOIS command works now in router environment, tested with two
routers, two servers and two clients.
* Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
in router environment (as it is almost equivalent to WHOIS) but
hasn't been tested thoroughly. Added new functions:
silc_server_command_identify_parse
silc_server_command_identify_send_reply
silc_server_command_identify_from_client
silc_server_command_identify_from_server
* Disabled route cache adding because adding two different ID's with
same IP replaces the old cache entry thus giving wrong route.
The entry->router->connection is always the fastest route anyway
so route cache may not be needed. Of course, new routes maybe
established after receiving the ID when the entry->router->connection
might not be anymore the most optimal.
Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Add route cache for received ID for fast routing.
* Added silc_server_packet_route to route received packet on router
that is not destined to us.
* Renamed silc_server_get_route to silc_server_route_get.
* Added id_string and id_string_len fields into SilcServer to
include encoded ServerID for fast comparing without excess
encoding of the ID's.
* Cleaned up WHOIS command on server side. Added following static
functions:
silc_server_command_whois_parse
silc_server_command_whois_check
silc_server_command_whois_send_reply
silc_server_command_whois_from_client
silc_server_command_whois_from_server
* Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
arguments in command replies. All command functions should be
updated to use this macro.
Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Minor typo fixes on command reply handling on server.
Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added silc_server_command_add_to_channel internal routine to add
the client to the channel after router has created the channel and
sent command reply to the server.
* Added generic silc_server_send_command to send any command from
server.
* Use static buffer with ID rendering instead of duplicating data.
Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed a channel user mode bug when joining to a channel server gave
everybody channel founder rights, oops.
* We mark ourselves as the router of the incoming server connection
if we are router ourselves. This way we can check in some packet
sending functions whether it is locally connected server. For
incoming router connections we put NULL.
* For router sending packets locally means now always sending the
packet cell wide; to local clients and local servers. For normal
server sending packet locally means sending it to only local
clients.
* Fixed the JOIN command to really work in router environment. If the
channel is created it is always created by the router. Router is
also responsible of making the initial joining to the channel,
sending JOIN notify to the sending server and distributing
NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
does not exist server doesn't do anything else but forward the
command to the router which performs everything.
* Added silc_server_send_channel_key function to send the Channel Key
payload.
* Added silc_server_create_channel_key to create new channel key. The
channel key is now re-generated everytime someone joins or leaves
a channel, as protocol dictates. Note: channel->key_len is the
key length in bits.
Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Splitted server.[ch] finally. Created now packet_send.[ch] and
packet_receive.[ch] to separate packet sending and receiving
routines. The server.[ch] now includes everything else including
actual packet processing (writing and reading data) and other
server issues.
Renamed silc_server_private_message_send_internal to
silc_server_send_private_message. The routine is still though
used only to relay private messages as server does not send
private messages itself.
Renamed silc_server_new_channel to silc_server_create_new_channel
and added new function sicl_server_new_channel that handles the
incoming New Channel packet. Added also new sending function
silc_server_send_new_channel to send New Channel Payload.
* Added new function silc_server_notify to process incoming notify
packet to the server/router. Server may then relay the notify
to clients if needed.
* Added new function silc_server_new_channel_user to process incoming
New Channel User packet. Router will redistribute the packet and
send JOIN notify to its local clients and locally connected servers
if needed. Normal server will send JOIN notify to its local client
on same channel when received this packet. Added also corresponding
sending function silc_server_send_new_channel_user to sent the
payload.
* Added boolean route argument to send_notif_to_channel and
packet_send_to_channel functions to attempt to route the packet
if it is TRUE and send only locally if it is FALSE.
Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* silc_server_replace_id now broadcasts the received replace ID
packet if it is not broadcast packet already. The router must
broadcast to inform other routers about changed ID.
* Added backpointer to server's router into SilcServer context in
silcd/server_internal.h.
* Fixed silc_server_packet_broadcast to send correct broadcast
packets.
* The channel key is now distributed to the local client as soon
as it is received from the router (in router environment) so that
no other packet may be sent for the channel until client has
received the key.
* silc_server_remove_channel_user now broadcasts the received
Remove Channel User packet if it is not broadcast packet already.
The router must broadcast to inform other routers about removed
channel user.
* Added users field into SilcPacketContext that is a reference count
of the context. One can increase the reference count by calling
silc_packet_context_dup which is now changed to just increase the
reference count instead of duplicating the data. The reference
count is decresed by calling silc_packet_context_free that will
free the data after the reference count hits zero.
For now on the packet context and everything allocated into it
(including the raw packet from network) must be freed by calling
the new silc_packet_context_free function. Added also new function
silc_packet_context_alloc that must be used now to allocate the
context. This also means that if a routine is asynchronous from
silc_[client/server]_packet_parse_type the packet context must
be duplicated by calling silc_packet_context_dup. Otherwise it
gets free'd after silc_[client/server]_packet_parse_type returns.
Also, one must remember that if packet is duplicated then its
reference count must be decresed by calling the free function as
many times as it was duplicated.
* Changed SilcBuffer field from protocol contexts to SilcPacketContext
from both client and server.
Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Made joining to a channel working in router environment.
* Cleaned up JOIN command on server side and create function
silc_server_command_join_channel internal routine to make the
joining happen.
Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Changed silc_command_pending list to SilcDList. Also, added
`ident' field to SilcServerCommandPending structure to identify
the reply and to call correct callback.
Added silc_server_command_pending_check function to replace the
corresnponding macro. The silc_command_pending list is not
extern anymore.
* Added silc_command_set_ident into lib/silccore/silccommand.[ch]
to set identifier to previously allocated Command Payload. It
is used to set identifier for command when resending Command
Payload.
* Added silc_command_payload_encode_payload to encode Command
Payload buffer from SilcCommandPayload structure.
* Added silc_argument_payload_encode_payload to encode Argument
payload buffer from SilcArgumentPayload structure.
Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Changed WHOIS command to support router connection on server side.
The whois request is always sent to router unless the server is
standalone server. After server has received the reply from the
router will it send the reply to the client.
* Added silc_server_packet_broadcast into silcd/server.[ch] to
broadcast received broadcast packet. The function is used only
by router. The broadcast packet is always sent to the router's
primary route.
* Added silc_id_render function in lib/silcutil/silcutil.[ch] to
render given ID to printable string, for log files for example.
Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Made basic router to router connections working. At least they
can now connect to each other but nothing really works the way
they are supposed - yet.
* Added new initiator token to RouterConnection configuration
file in silcd/serverconfig.[ch]. It is used to tell whether we
are the initiator to the remote router or whether we'll expect
the other end to connect.
* Moved registering of listener task to silc_server_init, hence
the server starts listenning as soon as it is run, even if it
does not have connections to other routers. Let's see how well
this will work.
* Changed default connection retry timeouts for more suitable in
silcd/server.h.
* Removed cipher and such arguments from silc_idlist_add_client
and silc_idlist_add_server prototypes from silcd/idlist.[ch].
Added new function silc_idlist_add_data to add the keys and stuff
to any ID entry.
* Added SilcIDListData structure and added it to SilcClientEntry
and SilcServerEntry as their first field in the structure. This
way we can explicitly cast the ID entries to the SilcIDListData
structure and get common data for the entries. In past, we had
to first check what type of connection it is and then cast it to
correct ID entry type. Now, we can directly cast the opaque
pointer to the SilcIDListData (no matter what ID entry it actually
is) and get the data needed.
Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Wow, found a bug in scheduler. The scheduler uninitialized itself
in some circumstances even if threre were timeout tasks, though not
IO tasks, but tasks anyway. Now fixed.
* Defined SilcServerConnection structure to hold connection specific
stuff about directly connected servers and routers. The definition
is currently in silcd/server_internal.h. I thought about having
a bit more important role fro this struct but for now it is used
only when connecting to other server (or router actually).
* Added connecting retry support in server when connecting to
router(s). The retry feature implement exponential backoff
algorithm. Also, added SilcServerParams structure to hold default
parameters for server. For now, it include these retry settings
and are hard coded. After server is moded to be as Silc Server
Library this structure will be more important.
Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Changed client librarys channel->clients table to SilcList and
changed code accordingly.
Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Changed client's channel table to SilcList and changed code
accordingly. Also changed SilcChannelClientEntry to include back-
pointer to the channel so that client entry can use that structure
as list as well and we have fast cross-reference to the channel.
This change dramatically decreased the complexity of channel
handling with client entry and vice versa (removed one extra
loop when searching for channel entry from many functions).
* Changed server->sim from table to SilcDList and changed code
accordingly.
* NAMES command can now be used from user interface. It will show
the user list on the channel, neatly.
* Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
Code now saves realname of the user if it becomes available.
* Renamed configure.in to configure.in.pre and made ./prepare
script to automatically add correct version string to
configure.in which it creates from configure.in.pre.
Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* NAMES command reply now shows users mode with the nickname when
joining to channel.
* Moved silc_client_ch[u]mode[_char] functions from
silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
place sucks, they are utility functions and should be in some
other file.
* Fixed some unsigned int's to unsigned short's. Patch by cras.
* Fixed contrib/getopt*.[ch] to not require config.h. Patch by
cras.
Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Updated README.
* Added TRQ (efficient deque and list library) into lib/trq. This is
a very good list library that is currently used in the SILC. Defined
SilcList API over the library because I didn't like the API very
much. See lib/trq/silclist.h for the API and examples of how to
use the API. Fixed various places in the code to use the new
SilcList API. The SilcList is meant for lists that has a structure
already defined as a list. It is not suitable to add just some
context to the list (in TRQ, the context is the list actually).
So, I defined SilcDList that can be used for the purpose where
predefined list structure does not exit. This can be used as
such list. Now some context just can be added to the SilcDList.
Currently this list is not used in the SILC just yet, though there
are a lot places where this can replace dynamically allocated
tables and I will fix these places, later, to use SilcDList.
See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
and use TRQ internally).
Also fixed some annoying warning messages that the original TRQ
code generated. Also minor changes to TRQ's Makefile.in.
* Added support for querying by Client ID to both WHOIS and
IDENTIFY commands into server, as required by the protocol.
* Removed method function pointers from SilcBuffer structure. They
weren't used to anything and just increased the context size for
no good reason. This change also made silc_buffer_alloc and
silc_buffer_free functions inline functions.
* Disabled command flooding detection support until it's fixed so
that it accepts commands in but does not execute them more than once
in two seconds.
* Added silc_net_localhost(), to return local hostname, into
lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
that must be initialized before calling silc_client_init.
* Added new function: silc_server_send_notify_on_channels to send
notify messages to all channels client has joined. It is assured
that the message is sent only once per client.
* Moved silc_log_format (from lib/silcutil/silclog.[ch] into
lib/silcutil/silcutil.[ch] as silc_format function. The new
function is generic and is used by server as well, not only by
the logging routines.
* Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
the provided version string was not acceptable. Added new function:
silc_ske_check_version into lib/silcske/silcske.h. The function
must be implemented by the application (client or server) and it
does not reside in the SKE library. The function checks the version
string remote end sent.
* Added back pointers (to opaque context and to SilcSocketConnection)
into SilcPacketContext structure into lib/silccore/silcpacket.h.
* Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
duplicate packet context structure.
* Changed `notify' client operation to send same arguments as client
receives from server except for ID's. ID's are mapped to correct
ID entry and that is returned. Also, if channel entry is not sent
by server but the notify is for channel the channel entry is sent
to application (otherwise application doesn't know that it is for
channel (library gets it from packet's Destination ID)).
* Added silc_client_remove_from_channels into client library to
remove a client from all channels it has joined to. Used when
received SIGNOFF notify from server. Added also new function
silc_client_replace_from_channels to replace old ID entry with
new ID entry on all channels. Used when received NICK_CHANGE
notify from server.
* Fixed ID Cache list handling in silc_idlist_get_client in
lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
to get (or query) client by ID.
* Updated TODO list.
* Added connection authentication status message defined by the
protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
support for these into the code in client and server side.
* Added generic function silc_client_send_command to send any command
with variable argument list. Application should use this function
to send commands if the command functions provided by the library
does not suite for the application's user interface needs.
* Added new `failure' client operation. Application is notified about
received failure packet if client is executing a protocol. In this
case the protocol's execution has failed.
* Added SKE's end notify to send the SKE_SUCCESS notify message that
is required by the protocol.
* Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
error at our end.
* Added status flag to SilcSKE object to indicate realtime status
of the SKE protocol.
* Application receives now exactly same command reply arguments as
the library receives from server. However, if ID is received the
corresponding ID entry is returned to the application (eg. Client
ID is mapped to correct SilcClientEntry entry and that is returned).
Changed command_reply client operation due to this change.
* Changed all ID's in commands and in command replys as ID Payloads.
Change affected both client and server side codes.
All ID's sent in SILC network (with execption of ID's in SILC
Packet header) are sent in ID Payload to support variable length
ID's.
* Server now notifies nick changes and notifies all clients on
the channels about the new nickname (about the new Client ID,
actually).
* Implemented CMODE command to change channel modes. Supports all
channel modes defined by the protocol specs except ban and invite
lists. (Also, private channel key mode is supported but support for
setting private channel key in client is missing, thus, this mode
has no effect on client side (except that server requires that the
client uses private channel key and normal channel traffic does not
work anymore)).
Also, invite mode works per se, but INVITE command does not work
yet correctly, so you can set channel as invite only channel but
inviting clients to the channel does not work (it is yet to be
thought what's the best way to do it).
* Added new command SILC_COMMAND_CUMODE to change user mode on the
channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
Implemented CUMODE command to change user's mode on the channel.
Supports all modes defined by the protocol specs.
* Added NAMES command reply to return users modes on the channel.
* Removed unnecessary and slow ciphers from lib/silccrypt.
* Set SO_KEEPALIVE option to connection sockets by default.
* Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
* Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
redefined the Notify Payload into protocol specs.
* Added silc_id_payload_parse_id to get ID directly from raw
ID payload data.
Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Changed SILC_COMMAND_IDENTIFY in protocol specification to
accept searching by Client ID as well.
* Added support for LEAVE and SIGNOFF notify types in client library.
* Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
to parse ID Payload from raw data.
Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added flags parameter into silc_ske_assemble_security_properties
function in lib/silcske/silcske.[ch].
* Changed notify client operation to fit better for notify messages
sent by server. The notify payload received from server is now
passed to the application (after parsing it to SilcNotifyPayload).
It is application's responsibility to retrieve the arguments
from the payload and show the message the way it wants. The message
sent by server is implementation specific.
* Changed public keys to comply with the protocol specification.
Old public keys are not supported anymore and are not compatible.
* Removed nickname from Channel Payload as the latest draft removed
it. The client must resolve the nickname from the NAMES command
reply received when it joined the channel.
Also, changed all channel_xxxx_payload to channel_payload_xxxx.
Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed some errors in protocol specification drafts.
* Created lib/silccore/silcnotify.c to implement Notify Payload
encoding and decoding, lib/silccore/silcpayload.[ch] to implement
generic payloads described by protocol specifications. The file
includes implementations for ID Payload and Argument Payload.
* Changed Command Payload implementation to use the new Argument
Payload. Changed command_xxxx_payload to command_payload_xxxx
to comply with SILC coding conventions.
* Added suppport for Argument Payload handling in Notify Payload
implementation as protocol requires it. Added the new support
into server and client lib as well.
Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added support for multiple nicknames on same channel. [n] is
added locally to the nickname if there are more than one same
nicknames on the channel.
* Server now sends all nicknames that matched WHOIS request.
Client also shows the list received from server.
* Added TOPIC command to client side. User can now set and show
current topic on channel.
* Added MOTD command to client and server. Also, server sends the
motd when client connects to the server.
* Changed version strings to comply ISO 8601.
Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed protocol error handling in client library. It should now
cope even if the SKE fails for some reason.
* Made new protocol specification drafts for submitting to IETF.
* Implemented TOPIC command to server in silcd/command.c.
* Added two new notify types into lib/silccore/silcnotify.h:
SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
notify nickname change and topic setting/change on a channel.
* API change of command_reply operation in client library. The
application gets now the status type received from server as well.
Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Removed the function just added to lib/silcutil/silcschedule.[ch].
* Cras fixed and optimized the packet handling even further and
it should work now. Minor change to the prototype of function
silc_packet_receive_process in lib/silccore/silcpacket.[ch].
Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added new function into lib/silcutil/silcschedule.[ch]:
silc_schedule_with_fd to select() a specified fd. The function
returns after timeout expires or data arrives or goes. The
function is used by packet routines to wait that all data is
received from network.
* Fixed data reading from network in lib/silccore/silcpacket.c.
The code now assures that all data is read from the fd and then
continues packet processing. This was a bug fix since the code
used to drop some data in some circumstances.
* Added new function into lib/silcclient/client.[ch]:
silc_client_start_key_exchange to start key exchange after
connection has been established to server. The code internally
now uses this funtion but its main purpose was to provide it
for applications that perform their own connecting. After
application has created a connection it merely calls this
function to start the key exchange between client and server.
The library takes care of everything else after that.
Updated also lib/silcclient/README to explain the usage of
this new function.
* Do not send to application information that connection has
been established. Application gets notified it by connect
operation anyway.
Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Applied cras's patch to add silc_schedule_one function. The
function runs scheduler once and returns.
* Fixed the scheduler after cras messed it up. The timeout
handling works now as it's supposed to work.
* Added into lib/silccore/ silcnotify.h to include notify
message types support. Changed silc_server_send_notify*
functions, in server.[ch], to support those new notify types.
Added the support for the notify types into client library,
as well. Added new notify client operation into ops.h in
lib/silcclient/.
* Changed silc_server_packet_send_to_channel to send normal
packets instead of just channel message packets. The function
is now used to send the notify packets to channels. It is not
used to send channel message packets anymore, as server never
sends them anymore.
* Added explicit casting into lib/silcutil/silcbuffmt.c to few
va_arg()s as it seems to require it nowadays. I guess, if SILC
is compiled with older va_arg() the new code should work anyway.
Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Splitted core library. Core library (lib/silccore) includes
now only SILC protocol specific core (and common) components.
Created new utility library (lib/silcutil) that includes more
generic purpose stuff. The stuff for util library was taken
from the old core library. This was minor and easy split.
* Created SILC Client Library (lib/silcclient) that includes
implementation of the SILC client without user interface. This
was major move from silc/ directory. The code has been changed
so that it is transparent towards the user interface. The
silc/ directory includes now the same user interface as before
and it uses the new client library. Read lib/silcclient/README.
Basicly, the client library performs everything else related
to SILC except user interface handling. Also, configuration
files are considered to be part of user interface and library
does not handle them.
This change also changed a lot of structures, function naming etc.
Most important change was that SilcClientWindow object was
renamed to SilcClientConnection in the client library. Created
also new file lib/silcclient/ops.h. Also added new files
silc/local_command.[ch] and silc/client_ops.[ch].
All these changes were made to make it easier for user interface
designers to create what ever user interface for the SILC client
they want.
It is also expected that the server will be moved to lib
directory as well and SILC Server Library will be created;
sometimes in the future.
* Removed Local commands from lib/silccore/silccommand.h as
they are application specific and new client library does not
handle any of those anymore.
* Several functions moved to lib/silcutil/silcutilc.[ch] from
old client implementation in silc/.
* Added support for callback functions in SILC_LOG_* macros.
Application can now set its own callbacks that will be called
instead of using the default functions that will always print
the debug messages to stderr (or stdout). Also, debugging can
now be disabled by setting silc_debug to FALSE and re-enabled by
setting it to TRUE. Note, that logging will still work even
if debugging is disabled.
New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
silc_log_reset_callbacks, silc_log_set_debug_callbacks and
silc_log_reset_debug_callbacks.
* To enable debugging in silc client one must give now -d
option on command line.
* Changed silc_schedule_init to automatically allocate task queues
if they are not allocated before calling it.
Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added GMP 3.1 into math library.
Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
a channel in SILC network. The packet is used by servers and
routers to notify other routers that user has left a channel.
This little feature was missing until now. Added the feature
to protocol specification as well.
Added functions: silc_server_send_remove_channel_user and
silc_server_remove_channel_user into server.[ch].
* Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
lib/silccore/silcpacket.h. However, they are not implemented
yet.
Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed joining to a channel and sending channel messages
between server and router. The channel message sending should
now work inside a cell.
Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed the private message sending between server and router.
The private message sending should now work inside a cell.
* Added silc_server_replace_id into server.[ch] to replace
existing ID in the SILC network.
* Added silc_idlist_find_server_by, silc_idlist_replace_client_id
and silc_idlist_replace_server_id into idlist.[ch] in server.
Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed the server to server connections. Server can again now
connect to router. Router to router connections probably does
not work just yet.
Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added dynamic protocol registering support. Now protocols can
registered and unregistered on the fly. Patch by cras.
Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added lib/contrib directory to hold routines that some platforms
don't have but are needed by SILC.
* Added getopt.c, getopt1.c and getopt.h from GNU C library
into lin/contrib to provide getopt() and getopt_long() for
those who don't have it.
Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added AWAY command to client. When away message is set and
client receives a private message packet the client automatically
replies to the sender with the away message.
* Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
bug seemed to be the cause of recent problems when compiling
with gcc-2.95.
* Added version detection support to SKE protocol specification
and added the new changes to the SKE implementation as well.
There were other minor changes in the SKE protocol as well.
Many changes in lib/silcske/silcske.[ch] and in
lib/silcske/payload.[ch].
* Added ^U functionality, clear input line. Patch from cras.
Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Mainly small bugfixes on core library. Fixed some debugging
logging and buffer overflow in silclog.c.
* Updated config.sub and config.guess on the distribution tree.
Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added command lagging support in server. Client may execute
commands now only once in two seconds.
Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Optimized packet reception. MAC computation and checking is now
also more optimized. A lot previously duplicated code is now
used as generic by both client and server.
* Fixed key pair generation in clientutil.c
Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added into lib/silccore/silcbufutil.[ch] new function;
silc_buffer_realloc.
* Moved generic packet sending/encryption functions to
lib/silccore/silcpacket.[ch] from client and server. Some
rewriting of the functions.
* Moved all generic packet reception/decryption functions to
lib/silccore/silcpacket.[ch] from client and server. The
packet processing is now much cleaner in both client and server.
These were major changes in both client and server.
* Created many common functions in server to do packet sending.
Previously code were duplicated a lot, this has been removed
with these changes.
Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Rewrote major parts of the ID cache system. Don't know
whether it is better now or not but at least the API is more
cleaner now.
* Major rewrite on ID cache stuff on client because of the ID
cache API changes. Added idlist.c to client.
* Also major rewrite on ID cache stuff on server as well.
Major rewrite of idlist.[ch]. SilcXXXList's are now named
SilcXXXEntry's. We won't keep anymore idlist specific pointers
in hand, instead they are all put into the ID cache system now.
All server_idlist_* routines uses ID cache now instead of
traversing its own lists (those lists does not exist anymore).
SilcIDList though still exists. Also, SilcXXXEntry's are
now pointers.
Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Finally made the SKE implementation compliant to the protocol
specification. All mp integers are now binary encoded as
opposed being HEX encoded.
* Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
from binary data.
* Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
functions: silc_[encode/decode]_pem. Also added function
silc_encode_pem_file to PEM encode with newlines ('\n') for
saving into a file.
* SILC public keys are now encoded either PEM or binary. Same
option is for private keys as well. By default private keys
are binary encoded and public keys PEM encoded. Silly HEX
encoding were removed.
* Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
function to create fingerprints.
* Fixed a bug in SHA1; does not change the original data anymore.
* Partly implemented INFO command on client and server side.
Fixed CLEAR command. Changes to SERVER command; show current
server(s) when giving command without arguments. Added
VERSION command to client.
* Added check to server that unregistered connections cannot
execute commands (unless it is specificly allowed).
Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Fixed screen refresh.
* Fixed channel joining bug from client. On some circumstances
client tried to join to a channel it had already joined.
* Added public key verification process into client's protocol.c.
The client now verifies the public key from user and saves
it into ~./silc/serverkeys/ directory.
Added into: clientutil.[ch]: silc_client_verify_server_key.
* Changed SKE protocol's silc_ske_initiator_finish function
to accept callback function that verifies the received public
key. Removed old silc_ske_verify_public_key function.
Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
silc_pkcs_private_key[_data]_set.
* Made the password and public authentication more cleaner in
server's protocol.c.
* Removed historic and obsolete protocol `channel_auth' from
both client and server.
* Removed wrong way of sending command status messages from
server to client in server's command.c. The old way violated
protocol specification.
Changes to silccore/silccommand.[ch]: removed
silc_command_encode_status_payload -> not needed anymore,
changed silc_command_encode_payload_va to accept extra
argument on variable argument list. The argument type must
now be provided to the function. Also, added new function:
silc_command_encode_reply_payload_va which is same as
normal command_encode_payload_va except command status type
is provided as extra argument.
Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added ~./silc directory handling. The directory includes the
public and private keys for the client.
Added silc_client_check_silc_dir, silc_client_create_identifier
and silc_client_load_keys.
* Implemented SILC protocol compliant public key. Added public
and private key saving to and loading from files.
Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
Implemented: silc_pkcs_save_[public/private]_key[_data] and
silc_pkcs_load_[public/private]_key.
Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added silc_server_get_route (route.[ch]) to get connection
data for the fastest route for given ID.
* Implemented INVITE command on client and server. The command
were re-defined in the SILC Protocol Specification and the
implementation now complies with the specification.
* Implemented PING command on client and server.
* Implemented NAMES command on client and server. The server side
supports currently only normal server not router server yet.
Some changes to NAMES definition in SILC protocol specification.
Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Implemented LEAVE command on client and server.
* Previously deprecated SILC_PACKET_FORWARDED flag is now in use
again. This change was made to the protocol as well. Server
should not violate the protocol specification anymore.
Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
* Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
was tested. SOCKS4 was not but should work anyway.
