User-Visible OpenAFS Changes
OpenAFS 1.6.10 (in progress)
All platforms
* Don't hide the "version" subcommand in help output (11214)
* Documentation improvements (11126 11216 11222 11223 11225 11226)
* Improved diagnostics and error messages (11154 11246 11247 11249 11181
11182 11183)
* Build system improvements (11158 11221 11224 11225 11227..11241 11282
11342 11350 11353 11242 11367)
* Avoid potentially erratic behaviour under certain error conditions by
either avoiding or at least not ignoring them, in various places (11008
11010..11065 11112 11148 11196)
FreeBSD
* Support releases 9.3 and 10.1 (11368 11369)
All server platforms
* Added volscan(8) (11252..11280 11387 11388)
* Fixed a bug causing subgroups not to function correctly if their
ptdb entry had more than one continuation entry (11352)
* Logging improvements (10946 11153)
* Allow log rotation via copy and truncate (11193)
* Avoid a server crash during startup only observed on a single platform
and when using a 3rd party library under certain circumstances, which is
a collateral effect of the security improvements introduced in OpenAFS
release 1.6.5 (11075) (RT #131852)
All client platforms
* Raised the free space reported for /afs to the maximum possible value of
just under 2 TiB - the old value was 9 GiB on most platforms (10984)
* Reduced the amount of stack space used (11162 11163 11203 11164..11167
11338 11339 11364..11366 11381)
* Sped up a periodic client task which could be problematically slow
on systems with a large number of PAGs and files in use (11307)
* Fixed failure of the up command with large ACLs (11111)
* Avoid a potential crash of aklog (11218)
* Avoid potential crashes of scout and xstat_fs_test (11155)
Linux clients
* Support kernels up to at least 3.16 (11308 11309)
* Fixed a regression introduced in OpenAFS release 1.6.6 that made
checking for existing write locks incorrectly fail on readonly volumes
(11361)
* Fixed a regression introduced in OpenAFS release 1.6.8 that could
cause VFS cache inconsistencies when a previously-accessed directory
entry was removed and recreated with the same name but pointing to a
different file on another client (11358)
* Use the right path to depmod in Red Hat packaging to avoid dependency
calculation incorrectly failing unless a link /sbin -> /usr/sbin is
present on the system performing it (11171) (RT #131860)
* Do not ignore kernel module build errors (11205)
OpenAFS 1.6.9
All server platforms
* Fix for OPENAFS-SA-2014-002
OpenAFS 1.6.8
All platforms
* Documentation improvements (10751 10875 10931 10897 10883 10954 10955)
* Improved diagnostics and error messages (10756 10814 10949)
* Fixed a bug in RX that could make errors during packet reception go
unnoticed. (10733)
* Fixed a bug that made "vos size -dump" display the wrong size for
large volumes. (10933) (RT #131819)
All server platforms
* Change the default fileserver sync behavior from "delayed" to "onclose".
This means that explicit syncing only happens when a volume is detached.
(10809)
* Added the -offline-timeout and -offline-shutdown-timeout options to the
fileserver, to implement interrupting clients accessing volumes we are
trying to take offline. (6266 10799)
All client platforms
* When a client is shut down, it will give up its callbacks. The Windows
client has been doing this since 2007. Note that older fileservers
(1.3.50 to 1.4.5 and 1.5.0 to 1.5.27) had a bug in the implementation of
the relevant RPC that could cause crashes or other undefined behavior
when this happens. (6272 8840 10855)
* Restored the pre-1.6 behavior of "vos e" being an alias for "vos examine".
(10886)
* Avoid flooding logs with warnings about byte-range locks, by throttling
them per file. Also, make the messages more useful by including the
FID. (10836..10839)
* Avoid a possible panic during shutdown while tracing. (10932)
Linux clients
* Fixed a bug that could cause the "getcwd: cannot access parent
directories" problem (10804 10984)
* Avoid a delay when accessing uncached data in AFS in a confined
context under SELinux. (10598)
* Red Hat packaging improvements (10600 10767 10807)
OpenAFS 1.6.7
All server platforms
* Fix for OPENAFS-SA-2014-001
* Fix for a potential DOS attack against RX servers
OpenAFS 1.6.6
All platforms
* As of this release, OpenAFS no longer ships uncompressed source tarballs.
Tarballs are still shipped with both compression formats, gzip and bzip2.
(10131)
* Documentation improvements (10136 10314 10601)
* Improved diagnostics and error messages (9412 10085 10274)
* Avoid redefining "assert" in our public header files, which could
cause failures when building some applications using them. (10096)
* Fixes for parallel builds (10005 10309 10337)
* Added a -s switch to afscp (not installed by default) to help simulate
a slow client. (9416 9417)
* Added a -probe switch to vlclient test program (not installed by default)
to ping all vlservers in a cell in parallel. (9570)
All server platforms
* The fileserver now ignores any vice partitions with a NeverAttach flag
file present in the root directory. (RT #130561) (9470 9471)
* Restrict forcing CPS ("Current Protection Subdomain") recalculation in
the fileserver to administrators. Also fixed a bug that could cause this
operation to be incomplete. (9485 9487)
* Allow non-DAFS fileservers to attach unusable volumes, restoring pre-1.6
behaviour. (RT #131505) (9499)
* Restored the pre-1.6 behaviour when running vos examine for a volume
currently in a transaction, showing the volume as busy again rather than
offline. (9685 9915 9916)
* Reduced the minimum time a bos salvage takes from 5 seconds to 1. (9476)
* Fixed buserver to not segfault when started with the -servers option.
(RT #131706) (10166)
* Salvager fixes, addressing a wide variety of possible problems from
unnecessary salvaging to aborts (9282 9283 9457 9458 9459 9461 9462 9480
9481 10165 10167)
* Fixed a bug that could cause saved state information to be discarded
when restarting a large or busy fileserver, which negatively impacted
performance. (9683)
* Fixed a bug that could have caused undefined behaviour in the vlserver
in rare cases when a fileserver registered its addresses in the VLDB.
(9429)
* Added the -preserve-vol-stats switch to volserver, allowing it to keep
the access statistics across volume restore and reclone operations
instead of resetting them. (9477)
* Inserted an exponential delay between retries when bosserver attempts to
restart a server process. (9571 10199)
* Improved vldb_check (not installed by default) to cope with broken
vlentry names and volids, and provide more output to aid debugging.
(10268)
* Releasing a volume after adding a new RO site no longer touches any of
the existing RO sites, if the RW data hasn't changed since the last
release. (10174)
* Make the copyDate field for RO clones have the same meaning as for
remote RO volumes. Previously, the copyDate field for clones was updated
every time we released. (9451)
* Fixed potentially undefined behaviour in ptserver when too many pts
ids are allocated. (10124)
* Note that the server side NAT pings feature present in the prereleases
was removed before the final release, since no positive feedback
was provided during prerelease testing. (9420 10135)
Linux servers
* Start bosserver with -nofork in the systemd unit file, to allow systemd
to track its state (10093)
All client platforms
* No longer track file locks on read-only volumes. Write locks can't
succeed, read locks always will. Avoids log messages about this kind
of lock. (8910)
* Added the "fs flushall" subcommand, which makes the client discard all
cached data. This was previously available on Windows only. (9065 9388
9389 9390)
* Fixed a bug that could make the client incorrectly believe its cache
is up to date. This change could negatively impact AFS <-> DFS
translators, should those still be running anywhere. (8898)
* Several changes to avoid panicing in certain error conditions.
(9131 9287 10354 10355 10356 10357) (partially addressing RT #131747)
* Added the -rxmaxfrags switch to afsd, allowing to limit the number
of UDP fragments sent or received per RX packet. (9430)
* Build fixes for aklog on several platforms (RT #131716) (9917 10107 10275)
* Require that the AFS mountpoint specified in the cacheinfo file is
an absolute path. Relative paths result in a client that basically
works but is not fully functional. (10253)
* Fixed a bug that could cause one of the afsd threads to enter an infinite
loop (10431 .. 10436)
Linux clients
* Support Linux kernels up to 3.13 (10241)
* Fixed a bug that made readv/writev calls in AFS space fail with Linux
kernels where generic_file_aio_read exists but those operations have
not been switched to using aio_read/aio_write. This was a regression
introduced with release 1.6.3 and affected at least RHEL 5.9 kernels.
(10248)
* Fixed a similar bug making core dumps fail in AFS space, affecting
a much wider range of kernels including the most recent ones.
(RT #131729) (10254)
* Enhanced the keyring code to make PAGs work correctly on kernels with a
distribution specific change to the Linux keyring code. This affected at
least SLES 11 SP3 kernels. (10252)
* Fixed a bug that could make failures during PAG instantiation go
unnoticed. (10255)
* Fixed a bug that made compilation fail for Linux kernels without
keyring support. This affected at least the SLE 10 SDK and an
OEM version of SLES 11 SP1. (10325)
* Fixed build for kernels with user namespace support enabled. Likely
to be required for Ubuntu 14.04 and eventually other distributions.
(10456 10457 10458 10518 10472)
* Support RHEL 6.5 kernels, and possibly others with changes backported
from recent mainline kernels that touch getname/putname, by no longer
using those functions. Previously, the client could cause a kernel
panic when syscall auditing was enabled. (10578)
* Make tmpfs usable as the cache filesystem again. This had been broken
since kernel 3.1 (9950 10193)
* When starting the client fails, clean up the backing device information
created in sysfs, to avoid error messages during a subsequent start
and possible system instability later on (10454)
* Update Red Hat packaging to support Fedora >= 20, RHEL >= 7 and
ELrepo kernels (10597 10619 10622 10703 10704)
OS X Clients
* Support OS X 10.9 "Mavericks" (10519 10541 10542 10543 10548 10549)
AIX clients
* Fixed a bug that caused the 1.6 AIX client to never receive any RX
packets in the kernel. (RT #131725)
FUSE client
* Support Solaris 11 (9454 9455)
* Allow other users to access filesystems mounted by root. (9452)
FreeBSD
* Build tvolser and dvolser on this platform (10122)
* Several fixes to catch up with newer releases (10374 .. 10381)
NetBSD
* Build tsalvaged, tvolser and dvolser on this platform (10121)
* Fixed build on NetBSD 5 and newer. (10138)
OpenAFS 1.6.5
All platforms
* Fixes for OpenAFS-SA-2013-0003 and OpenAFS-SA-2013-0004
OpenAFS 1.6.4
All platforms
* Obey the jumbo/nojumbo settings for ubik servers (the DB servers)
too. In previous releases, those servers may have used jumbograms
even if they were not configured to do so. This change corrects
the actual behaviour, and will improve performance and reliability
for sites where jumbograms are problematic. It could cause a decrease
in performance for sites where jumbograms work, but those can turn
them back on manually.
* Dozens of fixes for common coding problems like use after free,
use of possibly uninitialised memory, reading or writing past the
end of arrays and potential NULL pointer derefences. Spotted by
code analysis tools or human inspection.
* Documentation improvements.
* Fixes and improvements to the diagnostic or log messages printed by
vos, the fileserver and others.
* Build fixes, making parallel builds more reliable with certain
configuration options and helping various platforms including
recent releases of IRIX, Solaris and several flavours of Linux.
* Avoid sending a small amount of data over the wire unencrypted
under certain conditions, and emit the correct error message in
this case.
All server platforms
* Avoid generating duplicate IDs for readonly and backup volumes,
which could happen under certain conditions.
* Allow the fileserver to return volume data like quota or free space,
which is available publicly elsewhere, without the additional access
check for read permissions on a volume's root directory the fileserver
performed before.
* The fileserver now emits a log message when it ran out of memory for
callbacks.
* Avoid several potential fileserver problems, including memory
corruption and segmentation faults, due to client bookkeeping.
* Avoid known cases of silent data corruption due to background syncs
on the fileserver, especially during Copy on Write.
* Make the fileserver sync behaviour runtime configurable. Up to 1.4.5,
we had synchronous syncs which were safe but really slow. Since 1.4.5,
we've had asynchronous syncs which are much faster but believed to
be the cause of rare data corruption issues, and while all known cases
of these happening are believed to be fixed in the 1.6.3 release, doubts
remain. This change allows choosing between those, and in addition allows
to turn syncs by the fileserver off altogether, thus relying on the vice
partition's backend filesystem and the operating system, or to just
execute them when a volume is detached. The default behaviour is
unchanged from releases since 1.4.5, but it's highly recommended to
consider the additional options this change provides. Future OpenAFS
releases will default to "-sync=none".
* For dbservers, avoid a situation where misinterpreting transient
network errors causes long-term issues with achieving ubik quorum.
All UNIX client platforms
* Improvements to the detection of an aklog-specific krb5 configuration
file, for the purposes of turning on "weak crypto" for aklog.
* Fixed a regression introduced in release 1.6.2 which caused the
supposedly persistent disk cache to be discarded upon client start.
(RT #131655)
Linux clients
* Support Linux kernels up to 3.10
* Fixed two bugs making it impossible to unmount a disk cache filesystem
after it has been used by the client. (RT #131613)
* Fixed a bug that could cause an oops with kernels 3.6 and later
OpenBSD
* Improved support for OpenBSD 4.9 to 5.3
OpenAFS 1.6.3
This release number had to be skipped for technical reasons.
OpenAFS 1.6.2.1
Linux clients
* Support Linux kernels up to 3.8.
* Make the init script cope with the output of ifconfig on recent Fedora.
OpenAFS 1.6.2
All platforms

* Avoid generating inode number 0 with md5 inodes (Gerrit 7276).
* Fix a crash when reading /proc/fs/openafs/unixusers (Gerrit 7914).
* Make PAG-less access use the real UID of the calling process
instead of the effective UID, when determining what credentials to
use (Gerrit 7931).
* Fix possible abuse of fs mkmount.
Prior to 1.6.2, users could crash a client by nesting volume mounts.
* Fix fileserver memory corruption on RHEL 6
Prior to 1.6.2, fileservers on RHEL 6 may crash under heavy load.
* Fix client page cache corruption on Linux
When multiple clients read and write to a file, the reading client
may see first page (4096 bytes) of a file as nulls.
* Support Linux kernels up to 3.7.
* Support newer glibc versions.
* Improve client systemd unit file.
* Update Red Hat packaging.

OpenAFS 1.6.0 (2011-08-15)
All platforms
* Substantial Rx updates to correct erroneous behavior.
* vos now properly deals with matching sites when servers are
multihomed.
* 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 and improve
Rx busy call channel error handling. (128671)
* Properly enable Rx connection hard timeouts.
* Rx NAT pings are not enabled until peer has answered.
* Initialize rx_multi lock before use.
* Avoid spurious crashes when initializing in "backup" client.
* Revert UUID support in vos.
* pt_util fixed to properly create new databases.
* MTU discovery now properly shut down on call reset.
* Avoid leaking references to hosts during callback break multi-Rx
operations. (129376)
* xstat tools now cope with differing timeval structures between
endpoints.
* Numerous fixes to command argument parsing.
* Documentation updates.
All server platforms
* A file descriptor leak which could result in corrupted files in the
fileserver was fixed. An IMMEDIATE upgrade from previous 1.5 release
fileservers is recommended.
* 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.
* 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.
* 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: ensure vnodes are not reallocated while in use due to
volume bitmap errors.
* Properly support large volume numbers (larger than 2147483647).
* Allow salvager to be run manually again when DAFS is being
used. (129458)
* Avoid leaking references to hosts during callback break multi-Rx
operations. (129376)
* Demand attach: unlink fileserver state file on standalone salvage.
* Salvager tries harder to detect linktable issues.
* Demand attach: don't attach volumes with special status set.
* Avoid crashing on host table exhaustion. Instead, defer clients.
Microsoft 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
* Icon tray state now conditionally set. (128591)
* Properly create new cell mount points in freelance mode.
* Avoid recursive offline volume checks.
* 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.
* 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.
* Add support for NTFS symlinks.
* Handle file search requests for virtual syscall ioctl file.
* Process SyncOps properly to enforce ordered operations.
* Avoid recursing during NewServer operations.
* Correct lock acquisition order during SMB locking.
* Add shutdown message to event log.
* Check offline volume status by policy rather than on each daemon
thread run.
* Return error on directory object not found instead of crashing.
* Improve error message output.
* afslogin.dll can start afsd_service if it's not starting or started.
* Optimize away release lock RPCs for deleted files.
* Background Daemon will not perform operations on deleted files.
* Resort recently used directories to the top of the LRU if the
directory is larger than the stat cache.
* Resort deleted objects to the bottom of the LRU.
* Use interlocked operations for state and queue fields to allow safe
bit set and clear on multiprocessor systems.
All UNIX client platforms
* Servers now marked down when GetCapabilities returns error.
* In-use vcache count is now properly tracked.
* 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.
* FUSE client support fixed for non-/afs mounts.
* 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)
* Fall back to afs3-vlserver SRV record values when afs3-ptserver SRV
record is not available.
* Avoid holding unneeded locks when probing server capabilties.

vcache flushing.
* Support for virtual network stacks.
* New RC script, updated packaging.
IRIX
* Properly create new vnodes to avoid crashing in the client.
Linux
* Support through kernel 2.6.39. Treat Linux 3.0 as Linux 2.6 for
sysname purposes.
* 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)
* Perform vcache eviction via a fast path before visiting vcaches
where sleep is needed.
* setpag() errors are now properly reported.
* 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.

* Check for unloaded kernel extensions when decoding AFS panics.
* Disable "get tokens at login" in prefs pane if AD authentication
plugin is configured.

used to select default behavior).
* A potential kernel panic during bulkstat operations is
fixed. (128511)
* 64-bit MacOS kernel performance is greatly improved. (128934)
