ADDITIONAL CHANGES IN 1.6.0PRE2
All platforms:
- Documentation updates.
- Don't stop Rx keepalives after an ackall is received, avoiding
spurious connection timeouts. (128848)
- Don't retry Rx calls on channels returning busy errors. (128671)
- vos will not die with a double free error at command completion.
- Properly enable Rx connection hard timeouts.
- Initialize rx_multi lock before use.
- Avoid spurious crashes when initializing in "backup" client.
All unix platforms:
- Check for /afs existance before starting, unless -nomount is specified.
- Avoid a potential panic when using /afs/.:mount syntax.
- Avoid a panic in memcache mode due to missing CellItems file.
All server platforms:
- Attempt to recovery more quickly from timed out volume release
transactions.
- Auditing now properly byte order swaps IP addresses when printing.
- vos split now has improved error handling.
- Many changes to again support Windows fileservers.
- During volume removal, data removal speed improved.
- Improve CPU utilization during volume attaching by DAFS.
- In salvager check-only mode, avoid potentially fixing a vnode.
- Fix support for large (greater than 2gb) volume special files.
- Salvager will not crash if multiple or bad volume link tables
are encountered.
- Avoid erroneous full dump by remembering which sites were out of date
at the start of the release.
FreeBSD:
- Remove support for "Giant" lock as we no longer need to use it.
- Don't sleep with AFS GLOCK.
- Properly enable 64 bit long long support.
- Restore support for FreeBSD 7 (128612)
- Fix locking issues at shutdown.
Linux:
- support through kernel 2.6.38.
- RedHat packaging now properly supports RHEL6.
- Use rx_Readv in cache bypass to improve performance.
- Properly handle 0-length replies during cache bypass operations.
- Properly handle non-contiguous readpage cache bypass operations.
- Do proper locking when transitioning to or from cache bypass.
- Avoid extra runs of vcache freeing routine. (128756)
MacOS:
- Check for unloaded kernel extensions when decoding AFS panics.
- Properly handle setpag errors. PAGs are not supported.
- Disable "get tokens at login" in prefs pane if AD authentication
plugin is configured.
OpenBSD:
- support through OpenBSD 4.8.
Solaris:
- Fix support for Solaris pre-10.
Windows:
- afs_config will not longer set the Tray Icon State
in the registry if the checkbox is not present in
the dialog. (128591)
- AFS Explorer Shell Extension now works from folder
backgrounds. Overlays for mount points and symlinks
are present in the dll, but are not registered at present
by the installers.
- Do not use RankServerInterval registry value as the value for
PerformanceTuningInterval.
- When the data version of a mountpoint or symlink changes,
the target string in the cm_scache_t object must be cleared.
- "fs checkservers" now includes vldb servers in the output
and only lists multi-homed servers once. A multi-homed
server that has at least one up interface is no longer
considered to be down.
- When asynchronously storing dirty data buffers to the
file server ensure that (a) the cm_scache_t object and
the cm_buf_t object are for the same File ID so that
locking and signalling work properly; and (b) if the
FID no longer exists on the file server, do not panic,
just discard the buffer.
- When processing VNOVOL, VMOVED and VOFFLINE errors perform
server comparisons by UUID or address and not simply by
cm_server_t pointer. Otherwise, server failover may not
succeed.
- Do not preserve status information for cm_scache_t objects
when the issuing server is multi-homed.
- Giving up all callbacks when shutting down or suspending
the machine is now significantly faster due to the use
of an rx_multi implementation. (This functionality is
still off by default and must be activated by a registry
value.)
- Race conditions were possible when updating the state
of the cm_volume_t flags and when moving the volumes
within the least recently used list.
- Ensure that the lanahelper library does not perform a
NCBRESET of each lan adapter when enumerating the
current network bindings. Correcting this permits OpenAFS
to work on Windows 7 when the network adapter settings
change.
- Fix creation of mount points and symlinks as \\AFS\xxxx
PREVIOUS CHANGES:
All platforms:
- vos now properly deals with matching sites when servers are multihomed.
All Unix platforms:
- Servers now marked down when GetCapabilities returns error.
- In-use vcache count is now properly tracked.
All server platforms:
- Fix ptserver supergroups support on 64 bit platforms.
- Demand attach salvaging doesn't use freed volume pointers.
- Properly hold host lock during host enumeration in fileserver.
FreeBSD:
- Fix socket termination on shutdown.
- Support for 7.2, 7.3, 7.4 and 8.2 included.
- References to vcaches are no longer leaked during root or reclaim.
Linux:
- Define llseek handler to avoid ESPIPE error in 2.6.37.
- Mount interface replaces get_sb (new for 2.6.37, not yet required).
- RedHat init script allows deferring for a new binary restart.
- DEFINE_MUTEX replaces DECLARE_MUTEX for 2.6.37.
MacOS:
- Correct return value from setpag syscall.
OpenBSD:
- Bug fixes for issues introduced previously in 1.5 series.
Solaris:
- Switch to ioctl() syscall replacement for Solaris 11 since syscall 65
is not safe.
