The 1.6.x changelog entries have been going directly on the
openafs-stable-1_6_x branch for ease of maintenance.

However, we don't want to skip those changes when mentioning changes
in OpenAFS 1.8, so pull back a copy onto master before adding
things for 1.8.

User-Visible OpenAFS Changes
OpenAFS 1.6.20 (Security Release)
All platforms
* Fix for OPENAFS-SA-2016-003: file and directory names leak due to
reuse of directory objects without zeroing the contents
(12461 12462 12463 12464 12465)
OpenAFS 1.6.19
All platforms
* Documentation improvements (12304)
* Fixes for test failures (12396 12415)
All DB server platforms
* Avoid potentially writing to an out of date volume location or protection
database, or losing a database write, which could happen in rare cases
under special conditions during database leader election
(12339 12389)
Solaris clients
* Allow the fsinfo::: DTrace provider to work with AFS files (12371)
Linux clients
* Don't commit more data to a file than was actually copied during writes,
which could happen on architectures with a page size > 4 KiB (12413)
* Fixed build on PPC64 with GCC 6.1 (12388) (RT #133407)
* Fixed build on x86_64 with recent GCC (12365 12366)
OpenAFS 1.6.18.3
Linux clients
* Support for mainline kernel 4.7 and distribution kernels with
backports from it (12348)
Solaris clients
* Fixed memory mapped I/O on files >= 4 GiB (12349 12350)
Note that there is a suspicion that this might break the client
on very old Solaris releases (2.6). If it does, the breakage should
occur at build time.
OS X
* Added tooling to build a package for OS X 10.10 "Yosemite" and
10.11 "El Capitan" (12335 12351)
OpenAFS 1.6.18.2
Linux clients
* Support for mainline kernel 4.6 and distribution kernels with
backports from it (12332)
* Switch back to the pre-1.6.18 algorithm for freeing unused vcaches.
While the new algorithm is still believed to be correct, it turned
out that at least on some kernels, including 4.5 and 4.6, the dentry
for the current working directory may be erroneously invalidated.
This could lead to errors like "Unable to read current working directory"
when a directory wasn't accessed for a few minutes. (12323)
* Use a secure URL to retrieve the CellServDB in the script to create
the Red Hat source package (12330)
FreeBSD
* Added sysname IDs for 10.2 and 10.3 to fix the build on those platforms
(12322)
OpenAFS 1.6.18.1
Linux clients
* Support for mainline kernel 4.5 and distribution kernels with
backports from it (12300..12302)
OpenAFS 1.6.18
All platforms
* Documentation improvements (12224 11675 11613 12197)
* Improved diagnostics and error messages (12129 12207 12185 12211 12113
12215 12216)
* Check that CellServDB entries are valid IPv4 addresses, to avoid
occasional hangs or potentially other erratic behaviour due to invalid
entries (12210) (RT #131794)
All client platforms
* Gracefully handle cases where a client shutdown sequence is initiated
while the client is already shutting down, rather than cause a panic
(12179)
* Fixed several bugs that could cause erratic behaviour when the write
offset into a file was more than 2 GiB beyond the file's current end
on the server (12213 12214)
All server platforms
* Avoid a possible volserver crash during volume dump or restore due
to invalid ACL entries (12127)
* Allow recovering from a DAFS fileserver operation which allocates a
new vnode but fails to update the vnode index, rather than crashing the
server (12209)
* Fixed a longstanding bug which could damage the volume location database
when "vos changeaddr" was run with "-oldaddr" and "-newaddr" and the
old address was present in a multi-homed entry (12089)
FreeBSD
* Added support for releases 10.2 and 10.3 (12232)
Linux clients
* Support for mainline kernel 4.4 and distribution kernels with
backports from it, alas at a performance penalty (12226 12227 12228)
(RT #132677 #132819)
* Avoid using excessive amounts of kernel memory for dynamically
allocated vcaches, by improving the algorithm to free unused ones
(12256 12257)
* In Red Hat packaging, make the init script use "ip" if available, with
"ifconfig" as a fallback (12193)
OS X
* Basic support for release 10.11 "El Capitan" (12212)
IRIX clients
* Fixed kernel module builds with optimization (12198) (RT #131261)
OpenAFS 1.6.17 (Security Release)
All server platforms
* Fix for OPENAFS-SA-2016-001: foreign users can create groups as
if they were an administrator (RT #132822) (CVE-2016-2860)
All client platforms
* Fix for OPENAFS-SA-2016-002: information leakage from sending
uninitialized memory over the network. Multiple call sites
were vulnerable, with potential for leaking both kernel and
userland stack data (RT #132847)
* Update to the GCO CellServDB update from 01 January 2016 (12188)
Linux clients
* Fix a crash when the root volume is not found and dynroot is not
in use, a regression introduced in 1.6.14.1 (12166)
* Avoid introducing a dependency on the kernel-devel package corresponding
to the currently running system while building the srpm (12195)
* Create systemd unit files with mode 0644 instead of 0755
(12196) (RT #132662)
OpenAFS 1.6.16
All platforms
* Documentation improvements (11932 12096 12100 12112 12120)
* Improved diagnostics and error messages (11586 11587)
* Distribute the contributor code of conduct with the stable release (12056)
All server platforms
* Create PID files in the right location when bosserver is started with
the "-pidfiles" argument and transarc paths are not being used (12086)
* Several fixes regarding volume dump creation and restore (11433 11553
11825 11826 12082)
* Avoid a reported bosserver crash, and potentially others, by replacing
fixed size buffers with dynamically allocated ones in some user handling
functions (11436) (RT #130719)
* Obey the "-toname" parameter in "vos clone" operations (11434)
* Avoid writing a loopback address into the server CellServDB - search
for a non-loopback one, and fail if none is found (12083 12105)
* Rebuild the vldb free list with "vldb_check -fix" (12084)
* Fixed and improved the "check_sysid" utility (12090)
* Fixed and improved the "prdb_check" utility (12101..04)
All client platforms
* Avoid a potential denial of service issue, by fixing a bug in pioctl
logic that allowed a local user to overrun a kernel buffer with a single
NUL byte (commit 2ef86372) (RT #132256) (CVE-2015-8312)
* Refuse to change multi-homed server entries with "vos changeaddr",
unless "-force" is given, to avoid corruption of those entries (12087)
* Provide a new vos subcommand "remaddrs" for removing server entries, to
replace the slightly confusing "vos changeaddr -remove" (12092 12094)
* Make "fs flushall" actually invalidate all cached data (11894)
* Prevent spurious call aborts due to erroneous idle timeouts (11594)
* Provide a "--disable-gtx" configure switch to avoid building and
installing libgtx and its header files as well as the depending
"scout" and "afsmonitor" applications (12095)
* Fixed building the gtx applications against newer ncurses (12125)
* Allow pioctls to work in environments where the syscall emulation
pseudo file is created in a read-only pseudo filesystem, like in
containers under recent versions of docker (12124)
Linux clients
* In Red Hat packaging, avoid following a symbolic link when writing
the client CellServDB, which could overwrite the server CellServDB,
by removing an existing symlink before writing the file (12081)
* In Red Hat packaging, avoid a conflict of openafs-debuginfo with
krb5-debuginfo by excluding our kpasswd executable from debuginfo
processing (12128) (RT #131771)
OpenAFS 1.6.15 (Security Release)
All client and server platforms
* Fix for OPENAFS-SA-2015-007 "Tattletale"
When constructing an Rx acknowledgment (ACK) packet, Andrew-derived
Rx implementations do not initialize three octets of data that are
padding in the C language structure and were inadvertently included
in the wire protocol (CVE-2015-7762). Additionally, OpenAFS Rx in
versions 1.5.75 through 1.5.78, 1.6.0 through 1.6.14, and 1.7.0
through 1.7.32 include a variable-length padding at the end of the
ACK packet, in an attempt to detect the path MTU, but only four octets
of the additional padding are initialized (CVE-2015-7763).
OpenAFS 1.6.14.1
Linux clients
* Support kernels up to 4.2
Due to changes to internal data structures with this kernel release,
the OpenAFS client can no longer reset the link count during path
lookups. Since volume root directories must behave like symlinks
instead of normal directories in order to satisfy Linux kernel
invariants, looking up paths containing more than 40 mount points
will fail with ELOOP on such kernels.
OpenAFS 1.6.14
All server platforms
* Prior to the OpenAFS security release 1.6.13, the Volume Location
Server (vlserver) RPC VL_ListAttributesN2() supported wildcard volume
name lookups via regular expression (regex) pattern matching. This
support was completely disabled in 1.6.13 because it was judged to be
a security risk due to buffer overruns in the implementation, as well
as the possibility of denial of service attacks where certain regular
expressions could cause excessive CPU usage in some regex
implementations.
Unfortunately, after 1.6.13 was released, it was discovered that
the native OpenAFS 'backup' system uses the VL_ListAttributesN2()
regex support to evaluate configured volume sets. If you use the
OpenAFS 'backup' system (or another backup system which relies on it,
such as Tivoli Storage Manager (TSM, aka Tivoli ADSM)), and are using
volume sets which require regular expressions for the volume name,
then those volume sets cannot be resolved by OpenAFS 1.6.13. The next
paragraph provides details on how to identify any affected volume sets.
OpenAFS backup volume sets may be described by fileserver, partition
name, and volume name. The fileserver and partition specifications
never require regular expression support. The volume name specification
always requires regular expression support except for when specifying
_all_ volumes via two special cases: the universal wildcard ".*", or "".
For example, volume name "proj" or "*.backup" or "homevol.*" all
require regex support - even if the specification contains no wildcard
characters and/or exactly matches an existing volume name.
As a result of this issue, OpenAFS 1.6.14 replaces the 1.6.13 changes
to VL_ListAttributesN2. 1.6.14 prevents the buffer overruns and
reenables the regex support, but restricts it to OpenAFS super-users
and -localauth only. This is sufficient to restore the OpenAFS 'backup'
system's ability to work correctly with any previously supported volume
set. The OpenAFS 'backup' commands are already documented to require
super-user authorization, so this restriction is moot for the backup
system.
There are no other direct consumers of the VL_ListAttributesN2() regex
support in the OpenAFS tree. However, the VL_ListAttributesN2 RPC is
publicly accessible and might be used by third party tools directly or
indirectly via OpenAFS's libadmin. Any such tools that issue
VL_ListAttributesN2 RPCs must now be executed using super-user or
-localauth tokens.
None of the other security fixes in OpenAFS 1.6.13 are known to have
any issues, and are still included unchanged in OpenAFS 1.6.14.
If there are any questions concerning the possible impact of OpenAFS
1.6.13 or 1.6.14 at your site, please contact your OpenAFS support
provider or the openafs-info@openafs.org mailing list for further
assistance.
OpenAFS 1.6.13
All server platforms
* Fix for CVE-2015-3282: vos leaks stack data onto the wire in the
clear when creating vldb entries
* Workaround for CVE-2015-3283: bos commands can be spoofed, including
some which alter server state
* Disabled searching the VLDB by volume name regular expression to avoid
possible buffer overruns in the volume location server
All client platforms
* Fix for CVE-2015-3284: pioctls leak kernel memory
* Fix for CVE-2015-3285: kernel pioctl support for OSD command passing
can trigger a panic
Solaris clients
* Fix for CVE-2015-3286: Solaris grouplist modifications for PAGs can
panic or overwrite memory
OpenAFS 1.6.12
All server platforms
* Avoid database corruption if a database server is shut down and then
brought up again quickly with an altered database (11773 11774)
(RT #131997)
All client platforms
* Fixed a potential buffer overflow in aklog (11808)
* Avoid a bogus warning regarding the checkserver daemon, which could be
logged during startup when the cache initialization was very fast (11680)
* Added documentation of the inaccuracy of the 'partition' field in
'fs listquota' output for partitions larger than 2 TiB (11626)
Linux clients
* Support kernels up to 4.1 (11872 11873)
* Avoid spurious EIO errors when writing large chunks of data to
mmapped files (11877)
OS X
* Build fixes required at least on OS X 10.10 Yosemite with the latest
XCode (11859 11876 11842..11845 11863 11878 11879)
OpenAFS 1.6.11.1
Linux clients
* Support kernels up to 4.0 (11760 11761)
FreeBSD clients
* Fixed kernel module build on systems with an updated clang which no
longer accepts the -mno-align-long-strings as a no-op (11809)
OpenAFS 1.6.11
All platforms
* Allow aklog to succeed creating native K5 tokens even when mapping
the K5 principal to a K4 one fails (11538)
* Build fixes (11435 11636)
All client platforms
* Avoid a potential kernel panic due to connection reference overcounts
(11645) (RT #131885)
* Avoid potential corruption of files written using memory mapped I/O
when the file is larger than the cache (11656) (RT #131976)
Linux clients
* Support kernels at least up to 3.19 (11549 11550 11569 11570 11595
11658..11662 11694 11752)
Note: By default this excludes kernels 3.17 to 3.17.2, which will leak
an inode reference when an error occurs in d_splice_alias(). The
module will build and work, but leak kernel memory, leading to
performance degradation and eventually system failure due to
memory exhaustion. Since it's impossible to detect this condition
automatically, the switch --enable-linux-d_splice_alias-extra-iput
must be passed to configure when building the module for those
kernels. The same would be necessary for any kernel with backports
of commit 908790fa3b779d37365e6b28e3aa0f6e833020c3 or commit
95ad5c291313b66a98a44dc92b57e0b37c1dd589 but not the fix in commit
51486b900ee92856b977eacfc5bfbe6565028070 in the linux-stable repo
(git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git) or
the corresponding changes on other branches.
* Fixed a regression introduced in OpenAFS release 1.6.10 which could
make the spurious "getcwd: cannot access parent directories" problem
return (11558 11568) (RT #131780)
* Avoid leaking memory when scanning a corrupt directory (11707)
OS X clients
* Support OS X 10.10 "Yosemite" (11571 11572 11611) (RT #131946)
Solaris clients
* Avoid reading random data rather than correct cache content when using
ZFS as the cache file system on Solaris >= 11, and fix potential similar
problems on other platforms (11713 11714)
FreeBSD
* Build fix for releases >= 11.0 (11610)
OpenBSD
* Support release 5.4 (11700)
OpenAFS 1.6.10
All platforms

* 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 11392)
* 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 11530)
FreeBSD
* Support releases 9.3 and 10.1 (11368 11369 11402 11403 11404)
* Makes a disk cache more likely to work on FreeBSD, though such
configurations remain not very tested (11448)
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)

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 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
