record is not available.
- Avoid holding unneeded locks when probing server capabilties.
- Do not attempt page flushes for directories.
Demand Attach Fileserver platforms:

(129880) This bug was in unissued pre5 only, not in pre4.

MacOS:
- Rework logic for bulk status operations to avoid a potential hang.
Solaris:
- Don't leave dangling function references if kernel extension fails to load.
Windows:
- aklog supports dotted Kerberos v5 principal names.
- afskfw library always attempts afs/cell@USER-REALM
- afskfw library must test return code from
krb5_cc_start_seq_get() or will trigger a null
pointer exception when using Heimdal.
- lock protected fields must be 32-bit in order
to avoid memory overwrite races.
CHANGES IN 1.6.0PRE5
All server platforms:
- Avoid leaking references to hosts during callback break multi-Rx
operations. (129376)
All UNIX platforms:
- Avoid a potential deadlock (which times out) when we need to allocate more
callback returns and must flush some already in use.
- Deal with libcom_err conflicts with other packages using it (e.g. krb5)
(128640)
AIX:
- Fix PAG usage to track by PAG identifier, not group list.
Irix:
- Properly create new vnodes to avoid crashing in the client.
Linux:
- Support 2.6.39.
- Avoid attempting to free stat cache entries when we are below user-specified
number of entries in use.
- Properly track user-specified number of stat cache entries to use as a
desired usage target.
- Don't read pages beyond EOF in the cache. (128452)
MacOS:
- Properly shut down AFS, closing the Rx socket in the upcall handler to
avoid attempting to process data after we can no longer do so.
NetBSD:
- Updates for platform support.
Windows:
- Fix caching of non-existent volumes. The test to
trigger an immediate CM_ERROR_NOSUCHVOLUME in
cm_UpdateVolumeLocation() was backwards.
- Prevent the background daemon from checking the
status of non-existent volumes. cm_CheckOfflineVolumes()
should skip volume groups with the CM_VOLUMEFLAG_NOEXIST
flag set.
- The afskfw library should return an error immediately
if the krb5_32.dll library cannot be loaded. Affects
afslogon.dll and afscreds.exe.
- No longer depend on leashw32.dll in afskfw library.
- NPLogonNotify must provide the user password in all
calls to KFW_AFS_get_cred(). It cannot count on a
credential cache being preserved between calls. Permits
tokens to be acquired for all cells listed in the
TheseCells registry value for a domain.
- Improve the trace logging from NPLogonNotify().
- Avoid a race when writing the cm_scache_t mountPointString
when acquiring mount point or symlink target data via
cm_GetData(). The race could result in bogus target
data being cached.
- Permit the use of des-cbc-md5 and des-cbc-md4 enctypes
as DES keys in asetkey.exe.
CHANGES IN 1.6.0PRE4
All server platforms:
- A file descriptor leak which could result in corrupted files
in the fileserver was fixed. An IMMEDIATE upgrade from previous
1.6 release candidates as well as 1.5 release fileserver is
SUGGESTED!
- Properly support large volume numbers (larger than 2147483647).
All platforms:
- Documentation updates.
Demand Attach Fileserver platforms:
- Allow salvager to be run manually again when DAFS is being used. (129458)
FreeBSD:
- New RC script, updated packaging.
Linux:
- Improve RPM building tools.
- setpag() errors are now properly reported.
MacOS:
- Preferences Pane behavior fixed for 1.6 series (version detection
is used to select default behavior).
- A potential kernel panic during bulkstat operations is fixed. (128511)
- 64-bit MacOS kernel performance is greatly improved. (128934)
Solaris:
- Properly report errors for AFS system call callers.
Windows:
- Properly create new cell mount points in freelance mode.
- Avoid recursive offline volume checks.
CHANGES IN 1.6.0PRE3
All platforms:
- Revert UUID support in vos.
- pt_util fixed to properly create new databases.
- Rx busy call channel error handling improved.
- MTU discovery now properly shut down on call reset.

- A deleted volume can now be recreated properly.
- Callbacks are again not broken during whole partition salvages.
- Positional vectored IO fixed for largefile (>2GB) capable systems.
- Fileserver per-client thread usage again properly enforced.
- Anonymous dropbox support improved and drawbacks documented.
Demand Attach Fileserver platforms:
- Ensure vnodes are not reallocated while in use due to volume
bitmap errors.
Linux:
- Perform vcache eviction via a fast path before visiting vcaches
where sleep is needed.
MacOS:
- aklog AuthorizationPlugin now provided.
Solaris:
- Corrected Solaris 11 startup script.
- vcache mappings freed on shutdown to avoid panic.
Windows:
- icon tray state now conditionally set (128591)
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
