[This changelog is out of date. Look at changelog.html]
maradns-0.0.01: First version of MaraDNS package. Added iso-8859-1 support
to JsStr routines. Added js_qappend and js_qprepend
functions there. In addition to js_qfgrep. All tested
functions work and are without error. (2001.02.17)
maradns-0.0.02: MaraHash functions--assosciative array methods utilizing
a hash--have been set up. This has the functions
mhash_create, mhash_js, mhash_inc, mhash_put,
mhash_get, mhash_undef, mhash_put_js, and mhash_get_js.
Debugging done--these functions can perform basic
get/put operatins with elements in an assosciative
array. (2001.02.18)
maradns-0.0.03: Some more work has been done. mhash_undef_js and
mhash_resize functions written and compile. (2001.02.18)
maradns-0.0.04: We now properly handle the case of trying to add an
element already there (return an error), and have
more error checking to make sure we don't crash
because of corrupt hash data. Added an interactive
test which lets the user interactively add, delete, and
view hash elements. Time to go to bed (2001.02.18)
maradns-0.0.05: Corrected mhash_resize to blank out the hash we resize to.
Create mtest.c program to test the creation of hash
elements. Time to get ready for church. (2001.02.18)
maradns-0.0.06: Added mara_tuple support and verified that hash collisions
are properly handled. Time to go to evening church recital.
(2001.02.18)
maradns-0.0.07: Good morning! Added mtuple_new, mtuple_put, and mtuple_get
functions. Fixed bug where mhash_inc would allow a return
value of 0. Fixed Makefile so make clean cleans up mtest
binary. Added bounds testing to mhash_resize hashtable size.
Time to eat breakfast. (2001.02.19)
maradns-0.0.08: Added js_anq_chars, js_alpha_chars, and js_an_chars to
JsStrCP object. (2001.02.19)
maradns-0.1.00: Begin work on handlers to handle various data types that
RFC1035 has. (2001.02.20)
maradns-0.1.01: Added some more RFC1035 data to MaraDns.h (2001.02.20)
maradns-0.1.02: Wrote first (test-only) server that listens on port 53.
Using this server to determine what kind of data resolvers
ask for. (2001.02.20)
maradns-0.1.03: Began work on debugging routines in Query. Time to go to
work (2001.02.20)
maradns-0.1.04: Debugged routines in Query.c that convert a RFC1035 question
in to a query. Added routine that converts a RFC1035 domain
name (with class) in to a dotted-decimal hostname.
(2001.02.20)
maradns-0.1.05: Added hname_2rfc1035, which does the reverse of
hname_translate. Beginning work on ctest, which is a
test DNS client, to see what kind of replies we get
from DNS servers. (2001.02.21)
maradns-0.1.06: ctest now sends correctly formed DNS queries to a DNS server
(2001.02.21)
maradns-0.1.07: Fixed potential overflow in rtest (probably never exploitable)
Discovered that DNS servers do not support QDCOUNT > 1 in DNS
queries. Made notes in "doc" about this. (2001.02.21)
maradns-0.1.08: Added read_rr_h. Also began work on decompress_data
(Ugh. rfc1035 compression is horrible.) (2001.02.22)
maradns-0.1.09: Had a good weekend. Got to see a friend of mine and his wife
get baptised. Continued work on decompress_data. It is
still buggy, but I am working out the bugs. (2001.02.26)
maradns-0.1.10: You know how to handle buggy code? Rewirte the code so
that it is simpler and less buggy. A lot of the overhead
I had was not needed to keep things secure. The docs
on how MaraDNS handles decompression have been revised
also. RFC1035 decompression now works, still need to
add MX and SOA, and possibly support for other data types
that get compressed (SRV, the obscure RFC1035 datatypes,
etc.) Also, get rid of some of the cruft variables in the
decompression code. (2001.02.26)
maradns-0.1.11: Support for MX and SOA, and a number of other formats that
may have compressed data in them now added to the
decompression routine. ctest now can parse any RR that
MaraDNS fully supports except TXT (A, NS, SOA, MX, CNAME,
HINFO), and is now a rather verbose dig replacment. Got
rid of the cruft variables in the decompression routine.
Next: Have a routine to decode TXT data.
(2001.02.27)
maradns-0.1.12: Added support for TXT in ctest resolver code. Made ctest code
more hardy--it validates all input and returns an error if
there is a problem at any point.
(2001.02.27)
maradns-0.1.13: Fixed bug where ctest resolver program did not print out SOA
replies (2001.02.28)
maradns-0.1.14: Beginning the retooling of code from the KiwiSpam package
to use assosciative arrays in ParseMaraRC.c. This will
be a fairly extensive code rewrite, considering the code I am
modding is somewhat hacky itself. (2001.03.01)
maradns-0.1.15: Continuing the retooling of code from the KiwiSpam package
to use assosciative arrays in ParseMaraRC.c. Yes, this whole
parser is a hack instead of a proper parser. Right now, the
single line parser groks foo["bar"] = baz. Next: get it
to grok foo = {} (2001.03.01)
maradns-0.1.16: Modified js_anq_chars handle just numerics. Made it
correctly handle just alphabetics. Renamed 'ctest' to
'askmara'. Rewrote askmara.c to have all labels in
another file (askmara_labels_en.h), to make translation
easier. (2001.03.02)
maradns-0.1.17: More ParseMaraRC.c hacking. Now, it can parse
'foo = {}', 'foo["bar"] = "baz"', and 'foo = "bar"'.
Next: Write the routine to read an entire maradnsrc (maybe
we should just call this mararc) and fill up the hash
table with the names of all of the zones. (2001.03.03)
maradns-0.1.18: More ParseMaraRC hacking (this this is a real hack.
A really bad hack. At least the elegant js_string lib
stops it from being a security problem). It now has
routines that can fill up an assosciative array based
on user-specified keys and values. Next: Routine that
reads the rc file, and, based on the data there, begins
reading zone files. The zone files will then be read in
turn, and then populate a hash. (2001.03.03)
maradns-0.1.19: Added routines to handle getting all of the keys of a hash
in series (in the semi-random order they are in the hash
table). Corrected errors in parseline code, it now
works with foo["bar"] = "baz" lines and no longer considers
foo["bar"] = baz legal. foo["bar"] = 1 is still legal.
(2001.03.04)
maradns-0.1.20: I have decided that MaraDNS will use UTF-8 to support
international characters in domain names. I have added
the draft RFC for UTF8 domain names and a description of
UTF8 in the docs. In terms of code, we now have code
that converts ISO 8859-1 to UTF-8. In addition, I have
written up a couple of documents describing the csv1
non-standard Zone file format, and how MaraDNS will
resolve a domain name. (2001.03.06)
maradns-0.1.21: Wrote utf8test to test the ability to convert ISO 8859-1
strings to UTF-8 strings. Found minor bug in code, fixed,
and now ISO 8859-1 strings are correctly copied. I had to
set up X and recompile xterm to support all this. Cleaned
up the comments in the js_notmatch_offset code (they were
never cleaned up from the Kiwi days). Clean up of some
code in Queries.c. Wrote about half of the line parsing
code for parsing csv1 lines. csv1 format doc clean
up. (2001.03.07)
maradns-0.1.22: Split off some of the routines in other files to new .c
files: ParseCsv1.c and Utf8.c. Created js_addbyte routine.
Added csv1test and example_csv1 files to test the csv1
parsing routines. Created js_changebyte routine.
ParseCsv1 routine now parses all data types except for the
SOA datatype. Next: SOA datatype, shortcut for PTR datatype.
(2001.03.07)
maradns-0.1.23: Changed js_atoi to return unsigned integers. Added support
for TXT and SOA records. Tested to make sure error
correction looks good. Next: PTR shorthand, more efficient
Makefile. (2001.03.07)
maradns-0.1.24: Added support for MX and "Unknown" (user-specified query
type) data types. Added support for '\xxx'-style escape
sequences, making it possible to have arbitrary data in
the csv1 zone file. (2001.03.08)
maradns-0.1.25: Added support for % in csv1 file. Revised csv1.format
document. Next: figure out a way to store "star records"
in the hash table in such a way as to not step on the
EDNS standards. And implement that method. (2001.03.09)
maradns-0.1.26: Made the code that parses mararc lines a little more
senisible. It's still hackish, but is somewhat pedantic
about what kind of syntax it accepts, returning errors
when wrong syntax is given to it. (2001.03.10)
maradns-0.1.27: Pasted in read/write/setup kvar code from the code that
parsed the kiwirc file in the kiwi2 anti-spam package.
Modified mararc code so that it can parse both simple
strings and dictionaries (Assosciative arrays)
Next: The code that populates the DNS lookup hash based on
the data read from the mararc file. (2001.03.11)
maradns-0.1.28: Made all of the string literals in ParseMaraRc.c labels which
point to entries in ParseMaraRc_en.h. Wrote and documented
Perl script which automates this kind of work.
I did the same with ParseCsv1.c (ParseCsv1_en.h).
(2001.03.11)
maradns-0.1.29: Installed a new verison of Linux on my Laptop (Esware 2.0r2,
a Spanish RedHat clone with the 2.4 kernel). Begun work
on MaraDNS.c. Next: continue work on MaraDNS.c
(2001.03.13)
maradns-0.1.30: Worked on the routine to fill up the "big hash" with the
appropriate data. Now, I need to replace the "dummy"
add_rr_to_bighash with a routine that adds the appropriate
rr to the big hash (if appropriate). (2001.03.14)
maradns-0.1.31: Additional work on that routine. Now, it correctly make
sure that we add the NS records for the zone before the
NS records, and also fixed some other bugs in this
routine. Next: Make add_rr_to_bighash really check the
authority of a record and and data to the big hash
(2001.03.15)
maradns-0.1.32: More work on the the populate+bighash routine. Now, when
a syntax error is encountered, MaraDNS makes a best-faith
effort to continue processing zone files. (2001.03.16)
maradns-0.1.33: Plugged up some memory leaks in MaraHash.c. Added a lot
of code which starts populating the big hash with data.
(2001.03.17)
maradns-0.1.34: Added some more security features: It now chroot's and
changes the uid if it is run as root. Also made a function
that adds a RR to the end of a chain of RRs before the first
NS RR. (2001.03.17)
maradns-0.1.35: Verified that records are placed in the bug hash correctly.
Next: We can now start making this a working DNS server.
Bind to the port, answering UDP queries using a simple
forking model. (2001.03.18)
maradns-0.1.36: Now we convert star records (record which start off with
a * label) to an EDNS-style format MaraDNS uses for its
internal hash of RRs (2001.03.19)
maradns-0.1.37: Placed the code that converts star records in a more sensible
location. Added a new element in the rr answer which is
a pointer to the query string (we need this so we can tell
the resolver both the question and the answer with the NS
records, and which IP addresses go with which answers in
the AR records) (2001.03.21)
maradns-0.1.38: Added the code that adds pointers to the corresponding A
records for MX, NS, and CNAME records. (2001.03.23)
maradns-0.1.39: At this point, MaraDNS binds to a port and listens to
incoming data. Next: Actually process the data that
she gets (2001.03.24)
maradns-0.1.40: MaraDNS now resolves hosts. It doesn't handle a lot
of cases where the resolution is not an exact match
(NS records for stuff below us, star records, etc.) nor
does it give us NS or AN records, nor the IP for a Cname
record (if applicable), but at least MaraDNS is finally
resolving. To do: js_string function for adding uint16s
and uin32s in a single fell swoop, and real name resolution.
(2001.03.25)
maradns-0.2.00: Incremented minor number in light of the fact MaraDNS now
actually resolves, albeit in a very limited fashion. Added
some QuickStart notes, and added the ability for uint16s and
uint32s to be added directly to the end of a JS_STRING
object. (2001.03.25)
maradns-0.2.01: Bugfix: SOA lines can now have percent escape sequences in
them. (2001.03.25)
maradns-0.2.02: Now, MaraDNS correctly returns NS records and AN records for
every query where it has NS and AN records in its local
database. While I wait for the clows at NSI to figure
out why we can't make maradns.com and maradns.org use
ns.maradns.com and ns.maradns.org as name servers for
both domains, I can test things with www.z.maradns.org
(2001.03.25)
maradns-0.2.03: I have made the directory structure a little cleaner. The
only problem I have now is that multiple Makefiles have to
be changed if I add a new object file. I also have improved
the way MaraDNS cleans up after her children. (2001.03.26)
maradns-0.2.04: New security feature: Maxprocs, which is a mandatory way
of limiting the resources MaraDNS uses. Added fix.perms
tool. (2001.03.26)
maradns-0.2.05: Cleaned up the makefile so that we don't have compiled
binaries in any of the directories after a "make clean" is
performed. Added support for CNAME and limited NS record
support. (2001.03.26)
maradns-0.2.06: A and CNAME queries are now case-insensitive. Changed
the bs_process routine to have domain-labels converted to
their lower-case format before octal processing is done
(so we can still have 'A' in a domain label with '\101')
Returns NS delegation if we asked for a host in a
sub-delegated domain. (2001.03.27)
maradns-0.2.07: Fixed bug in MaraDNS' handling of case folding. Added some
support for star records. (2001.03.27)
maradns-0.2.08: Added support for ddip addresses (An IP query for '127.1.1.1'
gives the IP '127.1.1.1'). Added almost full support for
star records. Only these somewhat silly star record cases are
not supported: Star records pointing to CNAMEs and to NSs
records. Added code that warns the user if they try to add
an unsupported star record type. Next: The code to give
out a "notfound" reply. (2001.03.28)
maradns-0.2.09: Moved check for star records attached to CNAME or to NS RRs
in the CSV1 parser, where it belongs. Added support for
"notfound" reply. Next: RFC1035 compression (ugh).
(2001.03.29)
maradns-0.2.10: My theory is that they made DNS comprssion so difficult to
implement out of fear that anyone would be crazy enough to
write their own DNS server. Continued work on the compression
routines. (2001.03.31)
maradns-0.3.00: The DNS compression routines now work. Also set up the server
to return "Not implemented" to the unimplemented requests for
zone transfers and the unimplemented requests for all RRs
attached to a hostname. (2001.04.01)
maradns-0.3.01: Fixed bug where the MX preference changed on DNS compressing
and DNS decompressing. (2001.04.01)
maradns-0.3.02: Added support for truncating headers. Began work on getzone
zone transfer client. (2001.04.03)
maradns-0.3.03: The getzone program in tcp now generates working, albeit
ugly (too many RR types are still marked 'U'), MaraDNS zone
files based on the data from a zone transfer. Also found and
fixed other bugs the popped up when stressing the various
queries routines with a full Zone transfer. Unreleated
to MaraDNS per se, MaraDNS now has a `real' web page. (Thanks,
Leo!) (2001.04.04)
maradns-0.3.04: TXT, A, and MX records are now "pretty printed" when downloaded
from a foreign zone. All seven RR types supported by MaraDNS
are now pretty printed. Fixed bug with the handling of
"umbrella" NS records. Fixed bug with the handling of high
serial numbers and extra-long TTL values. Next: the AXFR
server. (2001.04.04)
maradns-0.3.05: An entire parsing engine which processes ip-based ACLs has
been created, complete with recursive aliases. Zoneserver
now only needs the code that reads the client's request
and send them the zone they ask for (as long as they have
access). (2001.04.08)
maradns-0.3.06: Security fix: The zone transfer client now checks for and
disables any out-of-baliwick records it finds when performing
a zone transfer. Feature enhancment: Maradns now has a
working zone transfer server. (2001.04.10)
maradns-0.4.00: Stable branch: This is the stable branch of MaraDNS, which
will only be updated with security fixes. Made zoneserver
check the query type, and drop connection on anything
besides AXFR and IXFR (Hack: The zone server treats an IXFR
exactly like an AXFR). Also cleaned up the error
handling in the zone and udp server code in preparation to
make maradns multithreaded. (2001.04.11)
maradns-0.4.01: Bugfix: Fixed bug where SOA records were not properly loaded
when we have multiple zones. (2001.04.11)
maradns-0.4.02: Bigfix: Hacked zoneserver so that it can work as a zone server
in cases where the zone transfer client asks for the SOA
record before downloading the zone. Also: Added the ability
to verbosely log invalid queries sent to the DNS server,
and to have a log level of 0 make MaraDNS give out no logs
whatsoever. Next: Fix bug where the last line of a csv1
file is not parsed. (2001.04.12)
maradns-0.4.03: Bugfix: The zone server is now hacked up to give a
plausable-looking answer to a SOA request on the TCP port.
As a result, BIND 4 and BIND 8 will now transfer zones from
the maradns zoneserver. (2001.04.12)
maradns-0.4.04: More bug fixes: Plugged potential memory leaks in
js_buf_getline. Fixed bug where the last line of a
csv1 file was not read. Fixed makefile so that it cleans
files in new location of the zonefile stuff--it's now in
a directory called "tuzona". Next: Go from a multi-process
model to a single process model. (2001.04.12)
maradns-0.5.00: The UDP server no longer fork()s off processes to process
queries. I performed a mild stress test, where MaraDNS was
processing 81 queries a second for over an hour--MaraDNS
performed beautifully--memory usage did not increase, and
queries were fast during this test. I am making this
release the stable branch. Next: Get string literals out
of the code. (2001.04.12)
maradns-0.5.01: Bugfix: Since mail exchangers routinely ask for "all records"
queries (to get both A and MX records), I have hacked MaraDNS
to deliver A and MX records if a request for all records
is received. I still need to code the case of a request for
"all records" pointing to a CNAME, though. Also, I have
added a benchmark tool which times a DNS server by sending
50,000 queries to the server in question as quickly as
possible. (2001.04.13)
maradns-0.5.02: Most of the text messages that MaraDNS' various utilities
generate have been moved to separate files, which will make
localization easier. (2001.04.16)
maradns-0.5.03: If a "give me all records for a given hostname" query appears,
MaraDNS will now look for a CNAME with the same hostname,
returning only that if found (and she will only look for a
CNAME if an A and MX were not found), and if A, MX, and
CNAME records are not found, MaraDNS will see if the person
entered a dotted decimal ip and respond appropriately.
(2001.04.16)
maradns-0.5.04: Added more support for dotted decimal IPs in NS, CNAME, and
MX records. Added handles for code which will warn the user
of the presence of these dotted-decimal IP records. Fixed
bug where js_copy was not returning an appropriate value on
success (2001.04.17)
maradns-0.5.05: Phil Homewood generously supplied a patch that makes this
compiles on FreeBSD. In addition, he fixed a bug in the
Makefile in dns/Makefile which made it so bobbit.c
compiles instead of using the Linux-specific object file
(Which I didn't catch, since make clean didn't remove it
and make didn't recreate it). I also fixed a bug in
getzone.c which was introduced when I put the string
literals in a language-specific file. (2001.04.17)
maradns-0.5.06: The zone server for MaraDNS can now be run from inetd.
Due to the security implications of this (MaraDNS' IP-based
ACLs stop working when run from inetd), this will be an
undocumented feature. (2001.04.18)
maradns-0.5.07: Plugged some memory leaks in the zoneserver which, while
not currently a problem, could have been a problem if
I had started coding threads before plugging the memory
leaks. Some of the leaks were is the js_string library,
so that code base is a lot cleaner now. Made the
functions in ParseCsv1.c thread-safe. My friend Fatma
generously supplied a German translation of the error
strings in MaraDNS_en.h--we now have a MaraDNS_de.h which,
while not perfect, will be appreciated by the Germans.
(2001.04.18)
maradns-0.5.08: Begin a "stable" brach for the only-authoritative
non-threaded nameserver. Changed compiler option from
-g to -O2. Made RPM of MaraDNS-0.5.08. (2001.04.19)
maradns-0.5.09: The server crashes were causes by pointers that were
not correctly initialized to zero. The pointers causing
the crash have been initialized, and hopefully this one
will be crashproof. Next: Look for other incorrectly
initialized variables. (2001.04.20)
maradns-0.5.10: Code cleanup: I added -Wall as an option in the libs, dns,
and server directories. Cleanup of all the warnings that
-Wall generated. Added /etc/mararc and
/var/maradns/db.example.com to RPM file. (2001.04.20)
maradns-0.5.11: Tollef Fog Heen generously ran autoconf for MaraDNS. The
build process now consists of './configure;make'".
(2001.04.21)
maradns-0.5.12: Added better support for CNAME records: If the CNAME record
points to an A record, and we have the A record "on file",
MaraDNS will add the CNAME record to the ar section of the
reply. Also added support for getting the version number
for maradns via a 'erre-con-erre-cigarro.maradns.org.'
TXT query. Set things up so we can both a autoconf-based
and a non-autoconf-based build process, and we can switch
between the two).
Next: Branch off to development again, because I need to
get the zone server multithreaded. (2001.04.22)
maradns-0.5.13: Manpage for maradns added. (2001.04.22)
maradns-0.5.14: Added "no_fingerprint" feature which minimizes the
MaraDNS-specific features, making it more difficult
to determine which DNS server one is running. (2001.04.23)
