122 * Add a new protection error code (PRNAMETOOLONG) instead of silently
123 truncating names which exceed the maximum name length (PR_MAXNAMELEN).
125 * Add an implementation limit (50000) on the number of names/ids which can
126 be transmitted by unauthenticated clients to the ptserver, avoiding
127 excessive resource consumption from unauthenticated requests.
129 * Add the -config option to vos, pts, and aklog to specify the path to the
130 cell configuration files.
132 * Add more details in vos release -verbose output.
134 * Add the cacheout -encrypt option to encrypt communication between the
135 cacheout client and the fileserver.
137 * Add the command line options to the afsio program to enable encryption of
138 traffic between afsio and the fileserver (-clear, -crypt).
140 * Add the vos release -force-reclone option to force recloning the volume to
141 be released without forcing a full volume dump being transmitted to all
144 * Fix vos to avoid writing loopback addresses into the VLDB in
147 * Print bos and pts error messages to standard error instead of
150 * Improve formatting of the -help output of all commands.
152 * Change -n to -dryrun in all backup subcommands.
154 * Change the backup deletedump -port command line option to -portoffset.
156 * Add user and build host in the version string returned by
161 * Ubik servers using pthreads are now available and are used by default
163 * Remove periodic background fsync by the fileserver (ihandle fsync thread).
165 * Fix potential file handle leak in the file server ihandle caching layer.
167 * Disable the so-called "hot threads" feature in the file server. The hot
168 threads feature was intended as an optimization for dispatching incoming
169 calls to the current listener thread, but has been reported to incur a
170 performance penalty on modern multi-core systems.
172 * Do not permit creation of users with id of ANONYMOUSID.
174 * Do not save/restore host states in the fsstate.dat file for hosts which
175 are in the process of retrieving CPS information from the ptserver when
176 the fileserver is being shutdown. This fixes a bug in which the fileserver
177 will incorrectly block all threads following a restart.
179 * Add the ptserver -restrict_anonymous option to inhibit exposure of user
180 names from the ptserver.
182 * Do not truncate server log files by default when server processes
183 are started. The -transarc-logs option provides backward compatibility
184 with IBM AFS log handling on server startup. Log messages may be lost
185 in back-to- back restarts when a server is running in this mode.
187 * Reopen server logs on SIGUSR1. This may be used by third-party log
188 rotation tools, such as logrotate, to reopen the log file handles after
189 log files have been renamed.
191 * Fix various bugs when logging with -mrafslogs enabled.
193 * Dynamically reload the kerberos realm to AFS cell mapping (krb.conf) and
194 exclusions for mapping kerberos principals to AFS identities (krb.excl)
195 configuration when the CellServDB cell configuration file is touched.
196 Previously, a restart of the file server was required after updating the
197 kerberos mapping configuration files.
199 * Add a command line option (-restricted_query) to the vlserver and
200 volserver to restrict information queries about volumes to a specific
203 * Add a command line option to the server programs to specify an alternate
204 fully qualified log file name (-logfile).
206 * Add a command line option (-config) to the server programs to specify
207 an alternate path to the server configuration.
209 * Add a command line option to the ptserver and vlserver to specify an
210 alternate path to the database data files.
212 * Add a command line option to the volume server to enable encryption of
213 volume-server-to-volume-server-traffic (-s2scrypt).
215 * Increase the maximum number of LWP threads allowed for the ptserver and
216 vlserver from 16 to 64 (-lwp).
218 * Remove an unused file server command line option (-k).
220 * Fix an incorrect assertion in Demand Attach File Server which could cause
221 the file server process to abort in certain rare conditions.
223 * Deprecate the -bitmap-later configure option for non-Demand-Attach File
226 * Add -vhashsize support to non-Demand-Attach File Servers (DAFS).
228 * Add support for subnet ranges in the NetInfo and NetRestrict
231 * Add the GetXStats RPC to the audit log.
233 * Fix directory creation by bosserver when built for non-Transarc paths.
235 * Fix incomplete list of server addresses retreived by vos listaddr when the
236 vldb contains unreferenced multi-homed server entries.
238 * Remove obsolete bos blockscanner and unblockscanner commands that
239 were only needed for the removed MR-AFS functionality.
241 * Remove obsolete bos salvage options that were only used by the
242 removed MR-AFS functionality..
244 * Remove calls to the deprecated sbrk() function.
246 * Add an experimental feature to database servers to support ubik reads
247 while write transactions are in progress, enabled at build time with the
248 --enable-ubik-read-while-write configure option. This feature is not
249 considered ready for production usage at this time.
251 * Avoid filling the FileLog with "Volume x offline: not in service" when
252 a volume is administratively taken offline with vos offline.
254 * Print an error message when bosserver is started with an unknown
257 * Modify the volume updateDate when the volume is changed by a salvage.
261 * Add support for relative ACL changes with fs setacl. If a single plus (+)
262 or minus (-) character is appended to the rights' letters argument, the
263 new rights are computed relatively to the existing ones.
265 * Remove afsd -settime and afsd -nosettime support.
267 * Add the afsd -inumcalc option to specify the method used to calculate
268 inode numbers presented by AFS.
270 * Add the afsd -volume-ttl option to specify set the maximum amount of time
271 information retrieved from the vlserver will be cached, regardless of
272 callback expiry times.
274 * Return EIO on internal errors instead of the misleading ENOENT.
276 * Log ICMP errors received, if any, for unreachable servers.
278 * Improve performance of clients with multiple PAGs for different cells.
280 * Fix race condition between changing and using user tokens among cache
283 * Fix fs sysname for users with UID 2748 and 2750 when not running
286 * Add Perl bindings for the user-space cache manager library (libuafs).
288 * Fixes to the bypasscache feature.
290 * Fix fs getcacheparms miscounts.
292 * Remove the obsolete Netscape plugin.
296 * Remove Linux 2.2 and 2.4 support.
298 * Changes to avoid EIO errors with multiple processes doing intensive mmap
299 writing. (Drop PageReclaim AOP_WRITEPAGE_ACTIVATE.)
301 * Prevent fakestat data inconsistencies in certain cases (131855).
303 * Fix dentry leak which can cause a crash on shutdown.
305 * Fix improper use of ENOENT and avoid incorrect use of linux negative
308 * Improve error reporting when encountering corrupt directories.
310 * Improve rx error handling in the Linux cache manager.
312 * Rename kpasswd to kapasswd when packaging RPMs to avoid colliding with
315 * Do not use the obsolete --enable-largefile-fileservers configure option
318 * Use the RemainAfterExit systemd feature to avoid premature exit
319 when -afsdb is not given, for RPM packages.
321 * Remove Debian packaging files from the OpenAFS source tree. Debian
322 packaging files are currently maintained in the downstream Debian
325 * Add the sparc_linux26 sysname.

363 * Fix builds on MacOS 10.12 by building only the active architecture
368 * Use the native kernel module build system instead of an ad hoc
369 replacement build system.
371 * Remove FreeBSD packaging files from the OpenAFS source tree. FreeBSD
372 packaging files are currently maintained in the downstream FreeBSD Ports
375 * Stay up to date with new FreeBSD releases (through 10.3).
377 * Do not claim AFS_VM_RDWR_ENV
381 * Stay up to date with new NetBSD releases (through 7.x)
383 * Update to use cprng(9) as the randomness source on NetBSD 6.99/7.x.
385 * Build system updates for NetBDS 6.99.x
387 * Do not claim AFS_VM_RDWR_ENV

397 * Updates for AIX support.
399 * Fix build system for AIX exports.
401 * Add the uidpag and localuid runtime options to the aklog LAM plugin.
402 (These runtime options override the use of UID-based PAGs, which were

419 All DB server platforms
421 * Hold the DB lock while checking for an aborted write transaction (12516)
423 All file server platforms
425 * On demand attach fileservers, don't save or restore a client's host
426 state if CPS ("Current Protection Subdomain") recalculation for it is
427 in progress, to avoid fileserver thread exhaustion (12568)
429 * On demand attach fileservers, avoid flooding the log with error messages,
430 which could happen when the fileserver was restarted while a volume was
433 * Update a volume's "Last Update" time when its content is modified by
434 the salvager, to make the change visible in the output of "vos examine"
435 and to backup services (12633)
439 * Corrected the DCentries bucket counts for very large and zero length
440 files in the output of "fs getcacheparms -excessive" (12604 12605)
442 * Fixed a bug that prevented users with GID 2748 and 2750 from executing
443 the "fs sysname" command on clients running afsd with -rmtsys (12607)
445 * Provide a new -inumcalc switch for afsd to allow enabling the alternative
446 MD5 method of inode number calculation, which was previously only
447 possible on Linux and through the sysctl interface (12608 12632)
451 * Support for mainline kernel 4.12 and distribution kernels with backports
452 from it (12624 12626)
454 * Re-added the improved algorithm for freeing unused vcaches to reduce
455 memory consumption first introduced with the 1.6.18 release, together
456 with a fix for the issue leading to its removal in 1.6.18.2 (12448..12451)
460 * Fixed a crash while stopping the client on macOS 10.12 "Sierra" (12602)
467 * Build fixes required by recent compilers or platforms (12514 12521 12534
470 * Allow the bos server to start successfully in the presence of those, by
471 accepting a now checked return value indicating that the client ThisCell
472 and CellServDB already exist (12522)
476 * Support for mainline kernels 4.10 and - most likely - 4.11 and

574 10.11 "El Capitan" (12335 12351)
581 * Support for mainline kernel 4.6 and distribution kernels with
582 backports from it (12332)
584 * Switch back to the pre-1.6.18 algorithm for freeing unused vcaches.
585 While the new algorithm is still believed to be correct, it turned
586 out that at least on some kernels, including 4.5 and 4.6, the dentry
587 for the current working directory may be erroneously invalidated.
588 This could lead to errors like "Unable to read current working directory"
589 when a directory wasn't accessed for a few minutes. (12323)
591 * Use a secure URL to retrieve the CellServDB in the script to create
592 the Red Hat source package (12330)
596 * Added sysname IDs for 10.2 and 10.3 to fix the build on those platforms

614 * Improved diagnostics and error messages (12129 12207 12185 12211 12113
617 * Check that CellServDB entries are valid IPv4 addresses, to avoid
618 occasional hangs or potentially other erratic behaviour due to invalid
619 entries (12210) (RT #131794)
623 * Gracefully handle cases where a client shutdown sequence is initiated
624 while the client is already shutting down, rather than cause a panic
627 * Fixed several bugs that could cause erratic behaviour when the write
628 offset into a file was more than 2 GiB beyond the file's current end
629 on the server (12213 12214)
633 * Avoid a possible volserver crash during volume dump or restore due
634 to invalid ACL entries (12127)
636 * Allow recovering from a DAFS fileserver operation which allocates a
637 new vnode but fails to update the vnode index, rather than crashing the
640 * Fixed a longstanding bug which could damage the volume location database
641 when "vos changeaddr" was run with "-oldaddr" and "-newaddr" and the
642 old address was present in a multi-homed entry (12089)
646 * Added support for releases 10.2 and 10.3 (12232)
650 * Support for mainline kernel 4.4 and distribution kernels with
651 backports from it, alas at a performance penalty (12226 12227 12228)
654 * Avoid using excessive amounts of kernel memory for dynamically
655 allocated vcaches, by improving the algorithm to free unused ones
658 * In Red Hat packaging, make the init script use "ip" if available, with
659 "ifconfig" as a fallback (12193)
663 * Basic support for release 10.11 "El Capitan" (12212)
667 * Fixed kernel module builds with optimization (12198) (RT #131261)
670 OpenAFS 1.6.17 (Security Release)
674 * Fix for OPENAFS-SA-2016-001: foreign users can create groups as
675 if they were an administrator (RT #132822) (CVE-2016-2860)
679 * Fix for OPENAFS-SA-2016-002: information leakage from sending
680 uninitialized memory over the network. Multiple call sites
681 were vulnerable, with potential for leaking both kernel and
682 userland stack data (RT #132847)
684 * Update to the GCO CellServDB update from 01 January 2016 (12188)
688 * Fix a crash when the root volume is not found and dynroot is not
689 in use, a regression introduced in 1.6.14.1 (12166)
691 * Avoid introducing a dependency on the kernel-devel package corresponding
692 to the currently running system while building the srpm (12195)
694 * Create systemd unit files with mode 0644 instead of 0755
701 * Documentation improvements (11932 12096 12100 12112 12120)

710 the "-pidfiles" argument and transarc paths are not being used (12086)
712 * Several fixes regarding volume dump creation and restore (11433 11553
715 * Avoid a reported bosserver crash, and potentially others, by replacing
716 fixed size buffers with dynamically allocated ones in some user handling
717 functions (11436) (RT #130719)
719 * Obey the "-toname" parameter in "vos clone" operations (11434)
721 * Avoid writing a loopback address into the server CellServDB - search
722 for a non-loopback one, and fail if none is found (12083 12105)
724 * Rebuild the vldb free list with "vldb_check -fix" (12084)
726 * Fixed and improved the "check_sysid" utility (12090)
728 * Fixed and improved the "prdb_check" utility (12101..04)
732 * Avoid a potential denial of service issue, by fixing a bug in pioctl
733 logic that allowed a local user to overrun a kernel buffer with a single
734 NUL byte (commit 2ef86372) (RT #132256) (CVE-2015-8312)
736 * Refuse to change multi-homed server entries with "vos changeaddr",
737 unless "-force" is given, to avoid corruption of those entries (12087)
739 * Provide a new vos subcommand "remaddrs" for removing server entries, to
740 replace the slightly confusing "vos changeaddr -remove" (12092 12094)

748 "scout" and "afsmonitor" applications (12095)
750 * Fixed building the gtx applications against newer ncurses (12125)
752 * Allow pioctls to work in environments where the syscall emulation
753 pseudo file is created in a read-only pseudo filesystem, like in
754 containers under recent versions of docker (12124)
758 * In Red Hat packaging, avoid following a symbolic link when writing
759 the client CellServDB, which could overwrite the server CellServDB,
760 by removing an existing symlink before writing the file (12081)
762 * In Red Hat packaging, avoid a conflict of openafs-debuginfo with
763 krb5-debuginfo by excluding our kpasswd executable from debuginfo
764 processing (12128) (RT #131771)
766 OpenAFS 1.6.15 (Security Release)
768 All client and server platforms
770 * Fix for OPENAFS-SA-2015-007 "Tattletale"
772 When constructing an Rx acknowledgment (ACK) packet, Andrew-derived
773 Rx implementations do not initialize three octets of data that are
774 padding in the C language structure and were inadvertently included
775 in the wire protocol (CVE-2015-7762). Additionally, OpenAFS Rx in
776 versions 1.5.75 through 1.5.78, 1.6.0 through 1.6.14, and 1.7.0
777 through 1.7.32 include a variable-length padding at the end of the
778 ACK packet, in an attempt to detect the path MTU, but only four octets
779 of the additional padding are initialized (CVE-2015-7763).
785 * Support kernels up to 4.2
787 Due to changes to internal data structures with this kernel release,
788 the OpenAFS client can no longer reset the link count during path
789 lookups. Since volume root directories must behave like symlinks
790 instead of normal directories in order to satisfy Linux kernel
791 invariants, looking up paths containing more than 40 mount points
792 will fail with ELOOP on such kernels.
798 * Prior to the OpenAFS security release 1.6.13, the Volume Location
799 Server (vlserver) RPC VL_ListAttributesN2() supported wildcard volume
800 name lookups via regular expression (regex) pattern matching. This
801 support was completely disabled in 1.6.13 because it was judged to be
802 a security risk due to buffer overruns in the implementation, as well
803 as the possibility of denial of service attacks where certain regular
804 expressions could cause excessive CPU usage in some regex
807 Unfortunately, after 1.6.13 was released, it was discovered that
808 the native OpenAFS 'backup' system uses the VL_ListAttributesN2()
809 regex support to evaluate configured volume sets. If you use the
810 OpenAFS 'backup' system (or another backup system which relies on it,
811 such as Tivoli Storage Manager (TSM, aka Tivoli ADSM)), and are using
812 volume sets which require regular expressions for the volume name,
813 then those volume sets cannot be resolved by OpenAFS 1.6.13. The next
814 paragraph provides details on how to identify any affected volume sets.
816 OpenAFS backup volume sets may be described by fileserver, partition
817 name, and volume name. The fileserver and partition specifications
818 never require regular expression support. The volume name specification
819 always requires regular expression support except for when specifying
820 _all_ volumes via two special cases: the universal wildcard ".*", or "".
821 For example, volume name "proj" or "*.backup" or "homevol.*" all
822 require regex support - even if the specification contains no wildcard
823 characters and/or exactly matches an existing volume name.
825 As a result of this issue, OpenAFS 1.6.14 replaces the 1.6.13 changes
826 to VL_ListAttributesN2. 1.6.14 prevents the buffer overruns and
827 reenables the regex support, but restricts it to OpenAFS super-users
828 and -localauth only. This is sufficient to restore the OpenAFS 'backup'
829 system's ability to work correctly with any previously supported volume
830 set. The OpenAFS 'backup' commands are already documented to require
831 super-user authorization, so this restriction is moot for the backup
834 There are no other direct consumers of the VL_ListAttributesN2() regex
835 support in the OpenAFS tree. However, the VL_ListAttributesN2 RPC is
836 publicly accessible and might be used by third party tools directly or
837 indirectly via OpenAFS's libadmin. Any such tools that issue
838 VL_ListAttributesN2 RPCs must now be executed using super-user or
841 None of the other security fixes in OpenAFS 1.6.13 are known to have
842 any issues, and are still included unchanged in OpenAFS 1.6.14.
844 If there are any questions concerning the possible impact of OpenAFS
845 1.6.13 or 1.6.14 at your site, please contact your OpenAFS support
846 provider or the openafs-info@openafs.org mailing list for further
853 * Fix for CVE-2015-3282: vos leaks stack data onto the wire in the
854 clear when creating vldb entries
856 * Workaround for CVE-2015-3283: bos commands can be spoofed, including
857 some which alter server state
859 * Disabled searching the VLDB by volume name regular expression to avoid
860 possible buffer overruns in the volume location server
864 * Fix for CVE-2015-3284: pioctls leak kernel memory
866 * Fix for CVE-2015-3285: kernel pioctl support for OSD command passing
871 * Fix for CVE-2015-3286: Solaris grouplist modifications for PAGs can
872 panic or overwrite memory
878 * Avoid database corruption if a database server is shut down and then
879 brought up again quickly with an altered database (11773 11774)
884 * Fixed a potential buffer overflow in aklog (11808)
886 * Avoid a bogus warning regarding the checkserver daemon, which could be
887 logged during startup when the cache initialization was very fast (11680)
889 * Added documentation of the inaccuracy of the 'partition' field in
890 'fs listquota' output for partitions larger than 2 TiB (11626)
894 * Support kernels up to 4.1 (11872 11873)
896 * Avoid spurious EIO errors when writing large chunks of data to
897 mmapped files (11877)
901 * Build fixes required at least on OS X 10.10 Yosemite with the latest
902 XCode (11859 11876 11842..11845 11863 11878 11879)
908 * Support kernels up to 4.0 (11760 11761)
912 * Fixed kernel module build on systems with an updated clang which no
913 longer accepts the -mno-align-long-strings as a no-op (11809)
919 * Allow aklog to succeed creating native K5 tokens even when mapping
920 the K5 principal to a K4 one fails (11538)
922 * Build fixes (11435 11636)
926 * Avoid a potential kernel panic due to connection reference overcounts
929 * Avoid potential corruption of files written using memory mapped I/O
930 when the file is larger than the cache (11656) (RT #131976)
934 * Support kernels at least up to 3.19 (11549 11550 11569 11570 11595
935 11658..11662 11694 11752)
937 Note: By default this excludes kernels 3.17 to 3.17.2, which will leak
938 an inode reference when an error occurs in d_splice_alias(). The
939 module will build and work, but leak kernel memory, leading to
940 performance degradation and eventually system failure due to
941 memory exhaustion. Since it's impossible to detect this condition
942 automatically, the switch --enable-linux-d_splice_alias-extra-iput
943 must be passed to configure when building the module for those
944 kernels. The same would be necessary for any kernel with backports
945 of commit 908790fa3b779d37365e6b28e3aa0f6e833020c3 or commit
946 95ad5c291313b66a98a44dc92b57e0b37c1dd589 but not the fix in commit
947 51486b900ee92856b977eacfc5bfbe6565028070 in the linux-stable repo
948 (git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git) or
949 the corresponding changes on other branches.
951 * Fixed a regression introduced in OpenAFS release 1.6.10 which could
952 make the spurious "getcwd: cannot access parent directories" problem
953 return (11558 11568) (RT #131780)
955 * Avoid leaking memory when scanning a corrupt directory (11707)
959 * Support OS X 10.10 "Yosemite" (11571 11572 11611) (RT #131946)
963 * Avoid reading random data rather than correct cache content when using
964 ZFS as the cache file system on Solaris >= 11, and fix potential similar
965 problems on other platforms (11713 11714)
969 * Build fix for releases >= 11.0 (11610)
973 * Support release 5.4 (11700)
980 * Don't hide the "version" subcommand in help output (11214)
982 * Documentation improvements (11126 11216 11222 11223 11225 11226)
984 * Improved diagnostics and error messages (11154 11246 11247 11249 11181
987 * Build system improvements (11158 11221 11224 11225 11227..11241 11282
988 11342 11350 11353 11242 11367 11392)
990 * Avoid potentially erratic behaviour under certain error conditions by
991 either avoiding or at least not ignoring them, in various places (11008
992 11010..11065 11112 11148 11196 11530)
996 * Support releases 9.3 and 10.1 (11368 11369 11402 11403 11404)
998 * Makes a disk cache more likely to work on FreeBSD, though such
999 configurations remain not very tested (11448)
1001 All server platforms
1003 * Added volscan(8) (11252..11280 11387 11388)
1005 * Fixed a bug causing subgroups not to function correctly if their
1006 ptdb entry had more than one continuation entry (11352)
1008 * Logging improvements (10946 11153)
1010 * Allow log rotation via copy and truncate (11193)
1012 * Avoid a server crash during startup only observed on a single platform
1013 and when using a 3rd party library under certain circumstances, which is
1014 a collateral effect of the security improvements introduced in OpenAFS
1015 release 1.6.5 (11075) (RT #131852)
1017 All client platforms
1019 * Raised the free space reported for /afs to the maximum possible value of
1020 just under 2 TiB - the old value was 9 GiB on most platforms (10984)
1022 * Reduced the amount of stack space used (11162 11163 11203 11164..11167
1023 11338 11339 11364..11366 11381)
1025 * Sped up a periodic client task which could be problematically slow
1026 on systems with a large number of PAGs and files in use (11307)
1028 * Fixed failure of the up command with large ACLs (11111)
1030 * Avoid a potential crash of aklog (11218)
1032 * Avoid potential crashes of scout and xstat_fs_test (11155)
1036 * Support kernels up to 3.16 (11308 11309)
1038 * Fixed a regression introduced in OpenAFS release 1.6.6 that made
1039 checking for existing write locks incorrectly fail on readonly volumes
1042 * Fixed a regression introduced in OpenAFS release 1.6.8 that could
1043 cause VFS cache inconsistencies when a previously-accessed directory
1044 entry was removed and recreated with the same name but pointing to a
1045 different file on another client (11358)
1047 * Use the right path to depmod in Red Hat packaging to avoid dependency
1048 calculation incorrectly failing unless a link /sbin -> /usr/sbin is
1049 present on the system performing it (11171) (RT #131860)
1051 * Do not ignore kernel module build errors (11205)
1055 All server platforms
1057 * Fix for OPENAFS-SA-2014-002
1063 * Documentation improvements (10751 10875 10931 10897 10883 10954 10955)
1065 * Improved diagnostics and error messages (10756 10814 10949)
1067 * Fixed a bug in RX that could make errors during packet reception go
1070 * Fixed a bug that made "vos size -dump" display the wrong size for
1071 large volumes. (10933) (RT #131819)
1073 All server platforms
1075 * Change the default fileserver sync behavior from "delayed" to "onclose".
1076 This means that explicit syncing only happens when a volume is detached.
1079 * Added the -offline-timeout and -offline-shutdown-timeout options to the
1080 fileserver, to implement interrupting clients accessing volumes we are
1081 trying to take offline. (6266 10799)
1083 All client platforms
1085 * When a client is shut down, it will give up its callbacks. The Windows
1086 client has been doing this since 2007. Note that older fileservers
1087 (1.3.50 to 1.4.5 and 1.5.0 to 1.5.27) had a bug in the implementation of
1088 the relevant RPC that could cause crashes or other undefined behavior
1089 when this happens. (6272 8840 10855)
1091 * Restored the pre-1.6 behavior of "vos e" being an alias for "vos examine".
1094 * Avoid flooding logs with warnings about byte-range locks, by throttling
1095 them per file. Also, make the messages more useful by including the
1098 * Avoid a possible panic during shutdown while tracing. (10932)
1102 * Fixed a bug that could cause the "getcwd: cannot access parent
1103 directories" problem (10804 10984)
1105 * Avoid a delay when accessing uncached data in AFS in a confined
1106 context under SELinux. (10598)
1108 * Red Hat packaging improvements (10600 10767 10807)
1112 All server platforms
1114 * Fix for OPENAFS-SA-2014-001
1116 * Fix for a potential DOS attack against RX servers
1122 * As of this release, OpenAFS no longer ships uncompressed source tarballs.
1123 Tarballs are still shipped with both compression formats, gzip and bzip2.
1126 * Documentation improvements (10136 10314 10601)
1128 * Improved diagnostics and error messages (9412 10085 10274)
1130 * Avoid redefining "assert" in our public header files, which could
1131 cause failures when building some applications using them. (10096)
1133 * Fixes for parallel builds (10005 10309 10337)
1135 * Added a -s switch to afscp (not installed by default) to help simulate
1136 a slow client. (9416 9417)
1138 * Added a -probe switch to vlclient test program (not installed by default)
1139 to ping all vlservers in a cell in parallel. (9570)
1141 All server platforms
1142 * The fileserver now ignores any vice partitions with a NeverAttach flag
1143 file present in the root directory. (RT #130561) (9470 9471)
1145 * Restrict forcing CPS ("Current Protection Subdomain") recalculation in
1146 the fileserver to administrators. Also fixed a bug that could cause this
1147 operation to be incomplete. (9485 9487)
1149 * Allow non-DAFS fileservers to attach unusable volumes, restoring pre-1.6
1150 behaviour. (RT #131505) (9499)
1152 * Restored the pre-1.6 behaviour when running vos examine for a volume
1153 currently in a transaction, showing the volume as busy again rather than
1154 offline. (9685 9915 9916)
1156 * Reduced the minimum time a bos salvage takes from 5 seconds to 1. (9476)
1158 * Fixed buserver to not segfault when started with the -servers option.
1159 (RT #131706) (10166)
1161 * Salvager fixes, addressing a wide variety of possible problems from
1162 unnecessary salvaging to aborts (9282 9283 9457 9458 9459 9461 9462 9480
1165 * Fixed a bug that could cause saved state information to be discarded
1166 when restarting a large or busy fileserver, which negatively impacted
1169 * Fixed a bug that could have caused undefined behaviour in the vlserver
1170 in rare cases when a fileserver registered its addresses in the VLDB.
1173 * Added the -preserve-vol-stats switch to volserver, allowing it to keep
1174 the access statistics across volume restore and reclone operations
1175 instead of resetting them. (9477)
1177 * Inserted an exponential delay between retries when bosserver attempts to
1178 restart a server process. (9571 10199)
1180 * Improved vldb_check (not installed by default) to cope with broken
1181 vlentry names and volids, and provide more output to aid debugging.
1184 * Releasing a volume after adding a new RO site no longer touches any of
1185 the existing RO sites, if the RW data hasn't changed since the last
1188 * Make the copyDate field for RO clones have the same meaning as for
1189 remote RO volumes. Previously, the copyDate field for clones was updated
1190 every time we released. (9451)
1192 * Fixed potentially undefined behaviour in ptserver when too many pts
1193 ids are allocated. (10124)
1195 * Note that the server side NAT pings feature present in the prereleases
1196 was removed before the final release, since no positive feedback
1197 was provided during prerelease testing. (9420 10135)
1201 * Start bosserver with -nofork in the systemd unit file, to allow systemd
1202 to track its state (10093)
1204 All client platforms
1206 * No longer track file locks on read-only volumes. Write locks can't
1207 succeed, read locks always will. Avoids log messages about this kind
1210 * Added the "fs flushall" subcommand, which makes the client discard all
1211 cached data. This was previously available on Windows only. (9065 9388
1214 * Fixed a bug that could make the client incorrectly believe its cache
1215 is up to date. This change could negatively impact AFS <-> DFS
1216 translators, should those still be running anywhere. (8898)
1218 * Several changes to avoid panicing in certain error conditions.
1219 (9131 9287 10354 10355 10356 10357) (partially addressing RT #131747)
1221 * Added the -rxmaxfrags switch to afsd, allowing to limit the number
1222 of UDP fragments sent or received per RX packet. (9430)
1224 * Build fixes for aklog on several platforms (RT #131716) (9917 10107 10275)
1226 * Require that the AFS mountpoint specified in the cacheinfo file is
1227 an absolute path. Relative paths result in a client that basically
1228 works but is not fully functional. (10253)
1230 * Fixed a bug that could cause one of the afsd threads to enter an infinite
1231 loop (10431 .. 10436)
1235 * Support Linux kernels up to 3.13 (10241)
1237 * Fixed a bug that made readv/writev calls in AFS space fail with Linux
1238 kernels where generic_file_aio_read exists but those operations have
1239 not been switched to using aio_read/aio_write. This was a regression
1240 introduced with release 1.6.3 and affected at least RHEL 5.9 kernels.
1243 * Fixed a similar bug making core dumps fail in AFS space, affecting
1244 a much wider range of kernels including the most recent ones.
1245 (RT #131729) (10254)
1247 * Enhanced the keyring code to make PAGs work correctly on kernels with a
1248 distribution specific change to the Linux keyring code. This affected at
1249 least SLES 11 SP3 kernels. (10252)
1251 * Fixed a bug that could make failures during PAG instantiation go
1254 * Fixed a bug that made compilation fail for Linux kernels without
1255 keyring support. This affected at least the SLE 10 SDK and an
1256 OEM version of SLES 11 SP1. (10325)
1258 * Fixed build for kernels with user namespace support enabled. Likely
1259 to be required for Ubuntu 14.04 and eventually other distributions.
1260 (10456 10457 10458 10518 10472)
1262 * Support RHEL 6.5 kernels, and possibly others with changes backported
1263 from recent mainline kernels that touch getname/putname, by no longer
1264 using those functions. Previously, the client could cause a kernel
1265 panic when syscall auditing was enabled. (10578)
1267 * Make tmpfs usable as the cache filesystem again. This had been broken
1268 since kernel 3.1 (9950 10193)
1270 * When starting the client fails, clean up the backing device information
1271 created in sysfs, to avoid error messages during a subsequent start
1272 and possible system instability later on (10454)
1274 * Update Red Hat packaging to support Fedora >= 20, RHEL >= 7 and
1275 ELrepo kernels (10597 10619 10622 10703 10704)
1279 * Support OS X 10.9 "Mavericks" (10519 10541 10542 10543 10548 10549)
1283 * Fixed a bug that caused the 1.6 AIX client to never receive any RX
1284 packets in the kernel. (RT #131725)
1288 * Support Solaris 11 (9454 9455)
1290 * Allow other users to access filesystems mounted by root. (9452)
1294 * Build tvolser and dvolser on this platform (10122)
1295 * Several fixes to catch up with newer releases (10374 .. 10381)
1299 * Build tsalvaged, tvolser and dvolser on this platform (10121)
1300 * Fixed build on NetBSD 5 and newer. (10138)
1306 * Fixes for OpenAFS-SA-2013-0003 and OpenAFS-SA-2013-0004
1312 * Obey the jumbo/nojumbo settings for ubik servers (the DB servers)
1313 too. In previous releases, those servers may have used jumbograms
1314 even if they were not configured to do so. This change corrects
1315 the actual behaviour, and will improve performance and reliability
1316 for sites where jumbograms are problematic. It could cause a decrease
1317 in performance for sites where jumbograms work, but those can turn
1318 them back on manually.
1320 * Dozens of fixes for common coding problems like use after free,
1321 use of possibly uninitialised memory, reading or writing past the
1322 end of arrays and potential NULL pointer derefences. Spotted by
1323 code analysis tools or human inspection.
1325 * Documentation improvements.
1327 * Fixes and improvements to the diagnostic or log messages printed by
1328 vos, the fileserver and others.
1330 * Build fixes, making parallel builds more reliable with certain
1331 configuration options and helping various platforms including
1332 recent releases of IRIX, Solaris and several flavours of Linux.
1334 * Avoid sending a small amount of data over the wire unencrypted
1335 under certain conditions, and emit the correct error message in
1338 All server platforms
1340 * Avoid generating duplicate IDs for readonly and backup volumes,
1341 which could happen under certain conditions.
1343 * Allow the fileserver to return volume data like quota or free space,
1344 which is available publicly elsewhere, without the additional access
1345 check for read permissions on a volume's root directory the fileserver
1348 * The fileserver now emits a log message when it ran out of memory for
1351 * Avoid several potential fileserver problems, including memory
1352 corruption and segmentation faults, due to client bookkeeping.
1354 * Avoid known cases of silent data corruption due to background syncs
1355 on the fileserver, especially during Copy on Write.
1357 * Make the fileserver sync behaviour runtime configurable. Up to 1.4.5,
1358 we had synchronous syncs which were safe but really slow. Since 1.4.5,
1359 we've had asynchronous syncs which are much faster but believed to
1360 be the cause of rare data corruption issues, and while all known cases
1361 of these happening are believed to be fixed in the 1.6.3 release, doubts
1362 remain. This change allows choosing between those, and in addition allows
1363 to turn syncs by the fileserver off altogether, thus relying on the vice
1364 partition's backend filesystem and the operating system, or to just
1365 execute them when a volume is detached. The default behaviour is
1366 unchanged from releases since 1.4.5, but it's highly recommended to
1367 consider the additional options this change provides. Future OpenAFS
1368 releases will default to "-sync=none".
1370 * For dbservers, avoid a situation where misinterpreting transient
1371 network errors causes long-term issues with achieving ubik quorum.
1373 All UNIX client platforms
1375 * Improvements to the detection of an aklog-specific krb5 configuration
1376 file, for the purposes of turning on "weak crypto" for aklog.

1617 * "fs checkservers" now includes vldb servers in the output and only
1618 lists multi-homed servers once. A multi-homed server that has at
1619 least one up interface is no longer considered to be down.
1621 * When asynchronously storing dirty data buffers to the file server

1640 cm_volume_t flags and when moving the volumes within the least
1643 * Ensure that the lanahelper library does not perform a NCBRESET of
1644 each lan adapter when enumerating the current network bindings.

1657 immediate CM_ERROR_NOSUCHVOLUME in cm_UpdateVolumeLocation() was
1660 * Prevent the background daemon from checking the status of
1661 non-existent volumes. cm_CheckOfflineVolumes() should skip volume
1662 groups with the CM_VOLUMEFLAG_NOEXIST flag set.
1664 * The afskfw library should return an error immediately if the
1665 krb5_32.dll library cannot be loaded. Affects afslogon.dll and
1668 * No longer depend on leashw32.dll in afskfw library.
1670 * NPLogonNotify must provide the user password in all calls to
1671 KFW_AFS_get_cred(). It cannot count on a credential cache being
1672 preserved between calls. Permits tokens to be acquired for all
1673 cells listed in the TheseCells registry value for a domain.
1675 * Improve the trace logging from NPLogonNotify().
1677 * Avoid a race when writing the cm_scache_t mountPointString
1678 when acquiring mount point or symlink target data via
1679 cm_GetData(). The race could result in bogus target
1682 * Permit the use of des-cbc-md5 and des-cbc-md4 enctypes
1683 as DES keys in asetkey.exe.
1685 * aklog supports dotted Kerberos v5 principal names.
1687 * afskfw library always attempts afs/cell@USER-REALM
1689 * afskfw library must test return code from krb5_cc_start_seq_get() or
1690 will trigger a null pointer exception when using Heimdal.
1692 * Lock protected fields must be 32-bit in order to avoid memory
1695 * Add support for NTFS symlinks.

1705 * Add shutdown message to event log.
1707 * Check offline volume status by policy rather than on each daemon
1710 * Return error on directory object not found instead of crashing.
1712 * Improve error message output.
1714 * afslogin.dll can start afsd_service if it's not starting or started.
1716 * Optimize away release lock RPCs for deleted files.
1718 * Background Daemon will not perform operations on deleted files.
1720 * Resort recently used directories to the top of the LRU if the
1721 directory is larger than the stat cache.
1723 * Resort deleted objects to the bottom of the LRU.
1725 * Use interlocked operations for state and queue fields to allow safe
1726 bit set and clear on multiprocessor systems.

1747 (e.g. krb5) (128640)
1749 * Fall back to afs3-vlserver SRV record values when afs3-ptserver SRV
1750 record is not available.

3273 * The demand attach fileserver had a structure reference error, which
3274 has been correected.
3278 * Restores Windows 2000 compatibility.
3280 * Fixes a data consistency error between the output of NetWkstaGetInfo
3281 and NetServerGetInfo RPCs, specify the Lan workstation group name
3282 "AFS", and report server name as "AFS" instead of "\\AFS" when the
3283 caller asks for "\\AFS".
3285 * Enables executables to be run from \\AFS on Windows 7. Returns
3286 "Name not found" instead of "File not found" when a directory or
3287 file name cannot be found. This avoids loader errors when system
3288 dlls cannot be located in the executable directory.
3290 * Prevents cache manager from marking the file server "down" when the
3291 data returned in response to either RXAFS_FetchData64 or
3292 RXAFS_StoreData64 is invalid.
3294 * Adds pioctl data validation to the AFS Explorer Shell extension.
3296 All UNIX client platforms
3298 * A bug which could cause a kernel panic in 1.5.63 has been corrected.
3299 This would manifest as a GetDCache panic or oops.
3303 * aklog -setpag works again with recent kernels when keyring is in
3308 * When Fast User Switch is in use, AFS login is now handled correctly
3309 by the integration tool included with the preferences pane.
3311 * Several packaging bugs have been corrected.
3314 OpenAFS 1.5.63 (2009-09-11)
3318 * The restorevol command is now documented and installed as a user
3321 * The uss command now properly translates vldb entries to its expected
3322 format when handling them in all cases.
3324 * Documentation now refers to Kerberos instead of kaserver.
3326 All server platforms
3328 * bosserver now handles BosConfig.new when restarting, allowing
3329 configuration to be replaced at restart time rather than with bos
3330 delete and bos create. Documentation is updated to reflect this.
3332 * The demand attach fileservice not longer potentially hangs trying to
3333 terminate demand-salvages which have already exited.
3335 * The demand attach fileservice has been modified to avoid spurious
3336 'SYNC_putRes: write failed' warnings when some protocol messages
3337 cannot be acknowledged due to the sender terminating the connection.
3339 * In the event of failure to contact the vlserver or ptserver, the
3340 fileserver will not exit and trigger a forced salvage. It will
3341 continue to try in the background to contact the needed services.
3343 * The salvager can now repair certain cases of a damamged vnode index.
3345 * The accessDate metadata for a volume is now updated correctly.
3349 * CRITICAL: Some applications for example those based on Cygwin were
3350 unable to access data stored in the AFS name space. Explorer Shell
3351 also experienced inconsistent behavior. This is fixed.
3353 * CRITICAL: Multiple AFS pioctl requests issued nearly simultaneously
3354 by applications could result in pioctl responses being received by
3355 the wrong requester. This in turn could result in application
3356 crashes. symlink.exe, fs.exe, afslogon.dll, afscreds.exe, and the
3357 netidmgr afscred.dll plugin were all affected.
3359 * Some XP machines running 1.5.62 had trouble saving roaming profile
3360 data. This is fixed.
3362 * Integrated Logon (afslogon.dll) did not function with domain
3363 specific configurations.
3365 * Ensure that access denied and over quota errors experienced while
3366 storing data to the file server do not result in on-going retry
3369 All UNIX client platforms
3371 * Except on Solaris and AIX, the compiler may now be overriden at
3372 configure time by setting the CC environment variable.
3374 * afsd now properly deals with large cache partitions.
3378 * Build shared libafsauthent and libafsrpc.
3382 * Kernel module DKMS support now installs an unstripped module to
3383 allow debugging information to be collected.
3387 * Preferences pane properly updates token information.
3391 * klog will now properly handle passwords of 8 or fewer characters
3392 with an AFS string to key on hosts able to run 64 bit binaries.
3394 * A panic at AFS shutdown due to "NO PCB" on a udp_lock has been
3397 * The panic decoder script included in the source now properly handles
3398 32 and 64 bit panics.
3402 * Avoid defining AFS_KERBEROS_ENV globally as it creates a circular
3405 * Build shared libafsauthent and libafsrpc.
3409 * Build shared libafsauthent and libafsrpc.
3412 OpenAFS 1.5.62 (2009-08-28)
3416 * Numerous invisible changes to improve code maintainability,
3417 portability and enhanceability.
3421 * CRITICAL: Fixes two errors that can result in data loss when storing
3422 data to the file server.
3423 1. Failure to Store Portions of Unaligned Writes
3424 2. Failure to Store Data to File Servers Lacking Large File Support
3425 Read the announcement for more details:
3426 http://www.openafs.org/pipermail/openafs-announce/2009/000305.html
3428 * CRITICAL: The cache manager daemon thread could terminate when the
3429 machine enters suspend mode. This daemon thread performs the
3430 background check of down servers, offline volumes, callback
3433 * CRITICAL: Integrated Logon (afslogon.dll) was terminating
3434 unexpectedly. Error checking has been improved and NULL pointer
3435 dereferences after Lsa API calls fail have been eliminated.
3437 * For the first time, the OpenAFS SMB Server supports the DCE RPC
3438 services SRVSVC and WKSSVC. Browsing \\AFS with the Explorer Shell
3439 or NET VIEW will now be faster and provide additional functionality.
3440 No longer will cell names longer than 12 characters be truncated.
3442 * Improvements to DFS Referral request processing have been
3445 * Unnecessary DNS lookups of share names are avoided improving
3448 All UNIX client platforms
3450 * Non-Kerberos PAM modules work correctly again.
3454 * MacOS 10.6 (Snowleopard) is now supported, both 32 and 64 bit mode.
3456 * Updates to the AFSCommander preferences pane.
3458 * Installer now permits cell names with dashes.
3461 OpenAFS 1.5.61 (2009-08-06)
3465 * Correct another race condition in the Rx library that could result
3466 in an unexpected panic while freeing the Rx call iovq.
3468 * rx packet resend and data packets sent counts were incorrect.
3470 * fs setquota, fs setcachesize, vos setfields, and vos create now
3471 accept human readable orders of magnitude. (K, M, G)
3473 * fs listquota fixed to permit large quota sizes to be displayed.
3475 * Correct documentation of bosserver permissions requirements.
3477 * Modify vlserver to avoid potentially corrupting the database through
3480 * Generalized support for fast Rx timeout due to network
3483 All server platforms
3485 * Allow audit logs to be sent via sys5 IPC message queues instead of
3490 * If a file server becomes inaccessible while the cache manager has
3491 dirty buffers to write, the afsd_service buf_IncrSync thread can
3492 attempt to use 100% of the cpu.
3494 * Fix "fs newcell" which was broken in 1.5.60.
3496 * Do not attempt to synchronize dirty buffers if the associated volume
3497 is known to be unavailable.
3499 * Modify behavior of a Freelance mountpoint target that does not
3500 specify a cell. Instead of assuming the target volume is in the
3501 Freelance.Local cell, use the workstation "Cell" specified in the
3502 registry. A mountpoint target of "#root.cell." will now mean the
3503 root.cell volume in the workstation cell for the current session.
3504 If the workstation cell changes from "athena.mit.edu" to
3505 "andrew.cmu.edu", the referenced volume will also change without
3506 requiring that the mount point targets be altered.
3508 * Add cm_FindServerByUuid(). Re-implement RXAFS_InitCallBackState3()
3509 to permit the server Uuid to be used to lookup the server object and
3510 from that determine the cell. This permits callbacks that are
3511 received from alternate addresses to be processed with a known
3512 server object. Previously a request from an unknown server would
3513 clear all callbacks from all cells.
3515 * Fix a bug that prevented optimal performance when using a non-zero
3516 value for 'daemonCheckVolCBInterval'. As a reminder, when
3517 "daemonCheckVolCBInterval" is set to a non-zero value, all .readonly
3518 volume callbacks are automatically renewed 90 minutes before their
3521 * Fix automatic ranking of vldb servers whose values are obtained from
3522 the CellServDB file.
3524 * Add failover for RX CALL TIMEOUT errors when the volume is readonly
3525 or the call is to a vldb server.
3527 * Add registry based cell search functionality to NetIdMgr,
3528 afs_config.exe, and klog.exe.
3530 * afsconf_GetCellInfo() has been modified to perform gethostbyname()
3531 lookups on the host names in the CellServDB instead of using the
3532 specified IP addresses. This provides aklog, pts, vos, etc. the
3533 same CellServDB behavior that the Windows Cache Manager uses.
3535 * When updating the stat cache entry callback of a .readonly object
3536 from the volume group object, update the file server reference to
3537 ensure it matches the most update to date callback.
3539 * Add proper support for processing callbacks from multi-homed file
3540 servers. Instead of comparing servers by cm_server_t pointer,
3541 compare them by UUID when the UUID is known.
3543 * During a shutdown short circuit the offline volume check daemon
3546 * Return the error code of RXAFS_FetchData / RXAFS_StoreData in
3547 preference to an error code reported by rx_EndCall.
3549 * Add "PerFileAccessCheck" registry value to permit testing against
3550 experimental file servers that include per-file acl support. This
3551 value is intentionally undocumented. It is not to be used by
3552 production environment deployments.
3554 * Fix a bug introduced in 1.5.60 that prevents the afs netidmgr
3555 provider from obtaining tokens when referrals are in play.
3557 * Add "fs chown" and "fs chgrp" commands to permit the owner and group
3558 of objects stored in AFS to be set from Windows.
3560 * Avoid performing background daemon operations when the machine is
3561 going into suspend mode.
3563 * Perform offline volume checks in most recently used order.
3565 * Prevent crash when a data version for a cache object goes backwards.
3567 * Multi-thread safe library versions are now being generated and used.
3568 mtafsubik.lib, mtafsutil.lib, mtafsvldb.lib, mtafsvol.lib.
3570 * Microsoft SMB Redirector (mrxsmb.sys) support for
3571 ExtendedSessTimeout values are now available on XP through Windows
3572 7. Add functionality to autodetect if such support is present on
3573 the machine. If so, configure it if necessary and dynamically
3574 adjust the AFS Rx timeout values accordingly.
3576 All UNIX client platforms
3578 * Fix out-of-tree source builds.
3582 * GUI installer now asks for local cell information.
3584 * AFS Commander preferences pane is now installed by default.
3588 * Avoid kernel panics due to null pointer dereferences in the network
3589 interface poller kernel thread.
3592 OpenAFS 1.5.60 (2009-05-31)
3596 * Retry volserver transaction creation on failure.
3598 * Allow building HTML and PDF documentation from included XML copies
3599 of User Guide, Admin Guide and Quick Start Guide for Unix.
3601 * Documentation updates and additional documentation.
3603 * Add -encrypt support to pts client.
3605 * Convert MR-AFS fs commands to OSD commands.
3607 All server platforms
3609 * Updated background sync process in fileserver to avoid a race which
3610 could result in a volume being taken offline.
3614 * On April 9th Microsoft released a Hot Fix for Windows Server 2003
3615 SP2 that corrects a deadlock in the smb redirector and also adds new
3616 functionality that permits the AFS SMB server to be given a longer
3617 timeout than is normally the case. New functionality has been added
3618 to configure these additional LanmanWorkstation\Parameter values.
3619 (This functionality has been backported to XP SP3 and is scheduled
3620 to be released on June 5th.)
3622 * Fix RT#124787, a race condition between "fs flush <dir>", "fs
3623 flushvolume", or "fs flushall" and on-going directory operations
3624 that can result in afsd_service.exe crashing.
3626 * Release Notes, User and Administrator guides are now shipped as
3627 indexed Windows HtmlHelp Files. (.chm). Shortcuts are provided from
3630 * A method of specifying Client CellServDB information within the
3631 registry has been added that can be used to either override the
3632 CellServDB file or force the use of DNS lookups for a given cell.
3633 See the release notes for details.
3635 * The pioctl interface now properly handles drive letter substitution
3636 to UNC paths. (SUBST <d:> <\\afs\cell\path>)
3638 * The BackConnectionHostNames registry value configuration was broken
3639 when dynamic re-establishment of Netbios Name registrations was
3640 added. This release restores the functionality.
3642 * All hidden vos.exe commands are now revealed.
3644 * Attempts to store the same dirty file chunk from multiple threads
3647 * The IsPathInAfs test in Explorer Shell Extension and fs.exe now
3648 permits broken symlinks to be treated as being in AFS.
3650 * vos.exe commands that output 64-bit integer values once again do so.
3651 This was broken in 1.5.59.
3653 * Cygwin Import Libraries are provided in the SDK for all OpenAFS
3654 DLLs. This permits building cygwin applications against OpenAFS
3657 * NSIS installer does a much better job of cleaning up files left over
3658 from previous installs.
3660 * libafsconf.dll moved from Client\Program to Common directory as is
3661 is now used by all modules for CellServDB processing.
3663 All UNIX client platforms
3665 * Write back changes on last store for memcache to avoid discarding
3668 * Abstract disk cache support to allow for path, fh, inode based
3669 caches with no need for messy ifdef structures each time a new type
3674 * Support as a userland port.
3678 * Corrected structure definition for userspace cache manager to allow
3683 * Corrected client locking support.
3685 * Updated patch to stop deadlocking in the kernel during mmap.
3687 * Avoid oops when setting up groups for PAGs to match keyrings.
3689 * Use Linux fh-based cache in cases where possible by default.
3693 * Corrected structure definition for userspace cache manager to allow
3698 * Support for OpenBSD 4.5.
3702 * Corrected support for server-side vos split interface.
3705 OpenAFS 1.5.59 (2009-04-06)
3709 * Increased service priority class to "High" to match the priority of
3710 system components that are dependent upon the a timely response.
3712 * SMB error responses avoid returning errors that could confuse the
3713 Microsoft SMB redirector into disconnecting the connection to \\AFS.
3715 All UNIX client platforms (except MacOS X 10.4 and 10.5)
3717 * OpenAFS 1.5.59 contains fixes for the client issues addressed by the
3718 security advisories OPENAFS-SA-2009-001 and OPENAFS-SA-2009-002.

3743 * Fix several Ubik recovery issues.
3745 * Avoid leaking file references in the fileserver.
3747 * Fix a race in DAFS while closing vnodes, and another offlining
3750 * volserver interfaces for volume splitting client.
3754 * [RT 124293] A race condition exists which can result in a crash.
3756 * [RT 124276] If the vldb is out of sync with the contents of the file
3757 servers, afsd_service will retry too many times when a file server
3758 reports a volume as not being present. Now if the list reported by
3759 the vldb is the same as the previously seen list, then the retry is
3762 * [RT 124276] Read-only volume failover was broken in 1.5.53 whenever
3763 accessing a volume results in VNOVOL or VMOVED.
3765 * [RT 124276] Prior to 1.3.70 the volume server reference list was not
3766 reference counted and would be prematurely freed while in use. When
3767 reference counting was added in 1.3.70 a bug was introduced that
3768 could result in service reference list corruption.
3770 * Add Windows Application Event Log warning messages for "Client SMB
3771 MPX value too large" and "Client SMB Buffer Size too small".
3773 * Renaming of files across directory boundaries would result in an
3774 invalid handle error when attempting to access the files after the
3777 * Fix the handling of Tran2 Set Path Info RPCs. Do not fail when a
3778 smb file descriptor cannot be found. The whole point of using a
3779 Path Info function is because an smb file descriptor wasn't
3782 * More edge cases in which dynamic addition of Freelance root.afs
3783 entries would get the wrong FID or where the root.afs directory
3784 would not be refreshed.
3786 * Buffer overflow could occur if the workstation cell name was longer
3787 than 64 characters. Crashes could occur in afscreds.exe,
3788 afslogon.dll, and afsd_service.exe.
3790 * VNOSERVICE and VOFFLINE errors were leaking and were exposed to the
3793 * Log file server uuid values as part of the cm_server object when
3794 available. Dump the cm_server object list in response to "fs
3797 * Optimize the performance of resetting access control lists when
3798 tokens are set or removed.
3800 * Remove symlink recursion tests and increase max symlink count to 64

3861 * Undo the "UAC manifest fix" applied to afs_config.exe.
3863 * Ensure that Freelance allocation of vnodes follow the AFS convention
3864 of odd vnodes are directories and everything else is an even vnode.
3866 * Add Freelance logic to mount point and symlink evaluation functions.
3868 * Enhance smb_ParseASCIIBlock() so that it can handle all of the
3869 STRING formats defined by the CIFS Technical Report 1.0.
3871 * Validate the output of smb_ParseASCIIBlock() in all callers. Return
3872 CM_ERROR_BADSMB if the STRING field cannot be parsed.
3873 CM_ERROR_BADSMB will cause the contents of the packet to be logged.
3875 * If multiple SMB Raw Write operations were taking place at the same
3876 time, there could be data corruption because unique event objects
3877 were not generated for each Netbios receive operation.
3879 All UNIX client platforms
3881 * Userspace AFS library can now deal with large files when supported

3921 * A race condition in Rx leading to a panic has been corrected.
3923 * Rx idle time tracking has been corrected.
3925 * ubik clone server support has been corrected.
3927 All server platforms
3929 * Salvager no longer leaves cores in vice partitions.
3931 * The vol-dump tool now supports dumps larger than 2gb where possible.
3933 * Operations on multiple files now report all FIDs in the audit log.
3935 * butc XBSA support now works correctly on amd64.
3939 * The NetIDMgr AFS Provider automated configuration logic was broken
3940 by the introduction of Kerberos referrals. If the realm of the
3941 identity cannot be determined, the workstation cell is now assumed
3942 to belong to the newly created identity.
3944 * Avoid a reference count under flow during rename operations.
3946 * Avoid a crash caused by treating an arbitrary length directory
3947 search mask as an 8.3 mask.
3949 * Prevent rename operations if a case insensitive match for the target
3950 name already exists and does not refer to the object being renamed.
3952 * Increase the maximum number of background daemons to 64.
3954 * Fix the UAC manifest applied to afs_config.exe

4053 change notifications are processed simultaneously.
4057 * AFS claims more free space so Finder will attempt file copies.
4061 * Avoid spurious ENOENT when calling gwtcwd() on a volume root.
4063 * Avoid spurious ENOTDIR during fakestat.
4066 OpenAFS 1.5.53 (2008-09-26)
4070 * rx avoids many packet leaks.
4072 * rx jumbogram disabling now works (and is the default).
4074 All server platforms
4076 * Demand Attach fileserver tries to avoid issues tracking offline
4081 * Many potential deadlock conditions due to out of order lock
4082 acquisitions have been corrected.
4084 * A race condition resulting in an undercount on the cm_scache_t
4085 reference counts has been corrected.
4087 * An empty string when sent as an ioctl path is now properly
4088 interpreted as meaning the current directory. This affects "fs
4089 lsm", "symlink list", etc.
4091 * Fix smb string parsing differences where the smb protocol
4092 documentation does not match the actual Windows implementation.
4094 * Random access denied errors fixed.
4096 * A file server lock synchronization issue was corrected in SMB
4097 NTCreateX and NTTranCreate operations. This bug prevented properly
4098 operation when loading roaming profiles.
4100 * Fix a heap overwrite error during server probe operations if a new
4101 server is added while a probe operation is in progress.
4103 * Fix an LSA memory leak that was the result of an LSA error.
4105 * Do not leak cm_cell_t objects if the VLDB server lookup fails.
4107 * Only initialize rx mutex/lock objects once.
4109 * Do not nul terminate the AFS volume name when reported to Windows.
4111 * Improve VNOVOL error handling. Prevent updated vl information from

5100 * DNS registration is disabled for the loopback adapter, and we make sure
5101 Netbios is turned on.
5106 * Remove use of ubik_Call in the source code so prototypes are used.
5108 * Avoid synchrony in call from the fileserver to the ptserver.

5282 caused issues with 64 bit Intel most commonly) has been fixed.
5284 - Packaging fixes and updates.
5286 - Uninstaller added.
5288 - Fix large file support.
5292 - autoconf kernel feature testing has been restructured.

5312 - Cleanup for loopback mount of AFS on Solaris 10.
5314 - Avoid issues with stdio not supporting file descriptors above 255 on
5315 Solaris 8 and lower in the fileserver.
5319 All systems: Major bugfixes.
5320 New systems: MacOS 10.4 (PowerPC and Intel)
5326 - Several race conditions in the host tracking and handling in the fileserver
5327 which could cause inconsistent behavior and crashes have been fixed.
5329 - A fileserver bug where a reference to a volume could be leaked and later
5330 cause a deadlock as a result of a bulk status call
5332 - Reference counting of fileserver objects in unsigned 32 bit integers
5333 instead of signed 16 bit integers.
5335 - Avoid type mismatches when handling time values (betweemn 32 bit and 64 bit

5352 - asetkey is now included to ease Kerberos 5 integration for server
5355 - A new fileserver statistics collection including callback statistics was
5358 - man pages are now generated.
5362 - Fixes error message problems experienced by fs.exe and the AFS Explorer
5363 Shell Extensions related to the use of Universal Error Codes by the
5366 - Adds full SMB/CIFS support for byte range locking. In this implementation
5367 all locks are allocated locally and the AFS lock privilege is ignored.
5368 While this will not prevent two processes on different machines from
5369 simultaneously writing to the same file, it will prevent two processes
5370 on the same machine from doing so.
5372 - The UP server check period has been reduced to once every ten minutes to
5373 match the period used by the UNIX clients. The shorter period will
5374 assist clients maintain RX connections through NATs.
5376 - Fixes the DOWN server check logic to ensure that any server that responds
5377 to a check is marked UP unless it is in the process of restarting.
5379 - Add logic to better handle objects that no longer exist on the file server.
5382 - Prevent the removal of existing drive mappings by "afscreds.exe -M"
5384 - Fixes the procmgmt library so that it doesn't cause applications that
5387 - Improves the warnings written to the afsd_init.log file when the
5388 Windows RPC Protocol drivers are improperly configured.
5390 - Fixes "fs setserverprefs -vlserver". Multiple calls with the same
5391 server parameter could result in a crash of afsd_service.exe.
5393 - The SMB/CIFS layer was audited for reference miscounts and memory leaks.
5394 All SMB objects are now properly counted, locked, and released when
5397 - Prevent file truncation of the user does not have the appropriate access.
5399 - Token management was re-written to allow user tokens to be preserved
5400 during integrated login and freed after logoff is complete.
5402 - Added a mechanism by which abandoned SMB virtual circuits can be
5403 detected and the associated resources cleaned up.
5405 - Prevent the allocation of SMB file handles with a value of 0 or 0xFFFF
5406 which would be considered invalid by Windows applications.
5408 - Fixed the processing of cell names to ensure that they are always
5409 treated as case insensitive strings.
5411 - Fixed the network provider code to avoid querying the profile location
5412 if integrated login is disabled.
5414 - If a mount point string is empty, return Path Not Found to the application.
5416 - Windows returns WSAECONNRESET when an ICMP packet is received in response
5417 to a transmitted UDP packet that cannot be delivered. Do not mark the
5418 connection as bad but instead retry the request.
5420 - Fix the data written to the registry as part of the BackConnectionHostnames
5423 - Fixed the rx-lwp implementation to always generate unique rx call
5426 - The default "fs minidump" type now includes data segments.
5431 * -nosettime is now the default for afsd. Use "-settime" to get the
5434 * OpenBSD is now supported.
5436 * Mountpoint directory information is now only faked for cross-cell
5437 mountpoints when using the -fakestat flag (e.g. for the directories
5438 under /afs, but not for most other volumes mounted inside the cell).
5439 The -fakestat-all switch can be used to fake information for all
5442 * When fakestat is enabled on MacOSX, the Finder can be used to browse
5443 a fully-populated /afs directory. However, this precludes reliable
5444 use of entire volumes as MacOS bundles (i.e. containing a Contents
5445 directory in the root of the volume).
5447 * Mountpoint directory information can be faked by the cache manager,
5448 making operations such as stat'ing all cells under /afs much faster.
5449 This is enabled by passing -fakestat to afsd, but might not be stable
5455 * The kaserver now defaults to not allowing interrealm authentication,
5456 due to security vulnerabilities in the krb4 protocol. The new
5457 "-crossrealm" flag to the kaserver is provided to reenable interrealm
5458 authentication if desired.
5460 * RedHat Linux 9.0 is now supported.
5462 * Solaris 9 12/02 is now supported. Solaris 7 and 8 x86 should now
5465 * On Linux machines using 2.2 series kernels, 2.2.19 or higher is now
5468 * An OpenAFS 1.2.9 afsd will not work with kernel modules built from
5469 an earlier OpenAFS release. In general, using a mismatched afsd and
5470 kernel modules set is unsupported; it is not recommended that you use
5471 such a configuration on a regular basis.
5476 * Mountpoint directory information is now only faked for cross-cell
5477 mountpoits when using the -fakestat flag (e.g. for the directories
5478 under /afs, but not for most other volumes mounted inside the cell).
5479 The -fakestat-all switch can be used to fake information for all
5482 * HPUX 11.0 is now supported.
5484 * It is now possible for AFS to use Kerberos 5 directly, via rxkad 2b.
5485 See the OpenAFS 1.2.8 Release Notes for more information on using this
5488 * An NFS translator kernel module is now included and compiled by
5489 default for Solaris only.
5494 * MacOS X 10.2 is now supported. FreeBSD 4.3 and later support is
5495 included in this release, but is still under active development and
5496 should only be used by those doing active development on the OpenAFS
5499 * When fakestat is enabled on MacOSX, the Finder can be used to browse a
5500 fully-populated /afs directory. However, this precludes reliable use
5501 of entire volumes as MacOS bundles (i.e. containing a Contents
5502 directory in the root of the volume).
5504 * The fileserver will now use Rx pings to determine if clients are
5505 reachable prior to allocating resources to them, to prevent asymmetric
5506 clients from consuming all fileserver resources.
5511 * Mountpoint directory information can be faked by the cache manager,
5512 making operations such as stat'ing all cells under /afs much faster.
5513 This is enabled by passing -fakestat to afsd.
5515 * Solaris 9 FCS and Solaris 7 and 8 x86 are now supported.
5520 * A remote denial of service attack in the AIX and IRIX clients has been
5521 fixed. Users of those platforms are strongly encouraged to upgrade.
5523 * Fixed race conditions in fileserver that could result in crash.
5528 * Server logfiles now more consistant about format in which hosts are
5531 * vfsck on Solaris will now allow force runs (using -y flag) even if old
5537 * Cell aliases for dynroot can be specified in the CellAlias file in
5538 /usr/vice/etc or /usr/local/etc/openafs, in format "realname alias",
5539 one per line. They can also be managed at runtime with "fs newalias"
5540 and "fs listaliases".
5545 * Solaris 9 and Linux PA-RISC are now supported.
5547 * fileserver will not erroneously delay legitimate errors for 3 seconds
5548 after 10 errors are returned (e.g. stat() on a directory you can't
5551 * Rx MTU calculation now works for Irix, Solaris and Linux
5553 * If afsd is started with the -dynroot flag, /afs will be locally
5554 generated from the CellServDB. AFSDB cells will be mounted
5555 automatically upon access.
5557 * The namei fileserver allows vice "partitions" to be directories
5558 instead of partitions and will attach and display accordingly.
5559 Creating the file "AlwaysAttach" in the /vicepX directory is used as
5560 the trigger to attach it.
5562 * TSM support for butc no longer requires editing a Makefile, simply
5563 specify the --enable-tivoli-tsm configure option.
5565 * Linux builds no longer require source changes every time the kernel
5566 inode structure changes; the OpenAFS sources will now configure itself
5567 to the actual inode structure as defined in the kernel sources.
5572 * vfsck on Digital UNIX and Solaris will now refuse to fsck mounted
5578 * AFS now supports --prefix and the other directory options of
5579 configure. By default AFS builds assuming it will be installed in
5580 /usr/local. In order to get traditional AFS directory paths (/usr/afs
5581 and /usr/vice/etc) use the --enable-transarc-paths option to
5582 configure. More details on the new directory layout are found in
5588 * Windows 95/98/ME/NT/2000 - Consistent versioning: Installation, AFS
5589 Control Center, Client dialog boxes and properties pages for
5590 executables display a consistent OpenAFS version number. Installation
5591 detects previous installation and prompts the user for upgrade
5594 * Windows 95/98/ME/NT/2000 - Installation features: During installation
5595 the user can select the source of the CellservDB file, AFS home cell,
5596 and drive mappings. During installation a drive path mapping can
5597 include a variable that will be substituted with the current UserName
5600 * Windows 2000/NT - Integrated logon: The Integrated Logon feature
5603 * Windows 95/98/ME - Logon script features: The Windows 95/98/ME client
5604 now offers a command-line option for starting up the AFS client
5605 without authenication. It is now possilbe to start the AFS client
5606 first and obtain tokens, and map drives all through Windows scripts.
5607 This helps using Windows 95/98/ME client in Kerberos 5 environment.
5609 * Windows 2000/NT - LANA numbers: AFS client now scans the LANA numbers
5610 to establish the correct NETBIOS connection. NetBEUI is no longer
5611 needed. The user no longer needs to find the correct LANA number.
5613 * Windows 2000/NT - OpenAFS naming consistancy: Further progress has
5614 been made to remove references to "Transarc AFS" and replace with
5620 * AFS now builds with configure. The README for building has been
5621 updated and includes full details.
5623 * A client system can now have multiple sysname values for @sys. They
5624 will be searched in order when looking up files in AFS. The
5625 -newsysname argument to fs sysname can be repeated to set multiple
5628 * A new system group is created for new cells (system:ptsviewers with id
5629 -203). If this group exists, members of this group can examine and
5630 read the entire protection database. They can examine all users and
5631 groups and can get the membership of any group.
5633 * A new program, pt_util has been added to the distribution. This
5634 program allows users to print the contents of the protection database
5635 or to edit the protection database without running a ptserver. It can
5636 be used to set up a new cell without ever running in noauth mode. Run
5637 pt_util -h for help.
5639 * The fs setcrypt and fs getcrypt commands have been added. These
5640 commands allow the system administrator to require that the client
5641 encrypt all authenticated traffic between the client workstation and
5642 AFS. The encryption used is weak, but is likely better than sending
5643 unencrypted traffic in most environments. Some functions, such as
5644 looking for a volume may not be encrypted, but data transfer certainly
5645 is. By default data is not encrypted. At this time no significant
5646 experimentation with server performance has been conducted.
5648 * By default AFS is compiled with AFS_AFSDB_ENV, enabling the -afsdb
5649 option to be given to afsd on startup. If this option is used, then
5650 new cells will be looked up using AFSDB records stored in DNS if they
5651 are not found in CellServDB. This means that users can create
5652 cross-cell mountpoints in directories they control to access cells not
5653 in root.afs, and that cells in root.afs need not be in the client's
5656 * AFS database servers can be marked as read-only clones. Surround the
5657 hostname in square brackets on the bos addhost command and the
5658 database server will never be elected sync site. This is useful for
5659 cells distributed over a wide region.
5661 * The AFS servers now support the -syslog flag. This flag causes them
5662 to log to syslog rather than to files. This flag is not supported on
5663 NT. For all servers besides the salvager, the flag can also be
5664 specified as -syslog=facility, where facility is an integer facility
5665 code from syslog.h. A -syslogfacility option is provided for the
5666 salvager to accomplish the same goal.
5668 * If the --enable-fast-restart flag is given when configuring AFS, then
5669 the salvager supports the -dontsalvage flag which causes it to exit
5670 without salvaging any volumes. If this is configured into the third
5671 command of a fs process, then the fileserver will start without
5672 salvaging. It will fail to attach volumes that need salvaging and
5673 they can be salvaged manually. This provides significantly better
5674 server startup performance at the cost of administrative complexity.
5676 * If the --enable-bitmap-later flag is given when configuring AFS, then
5677 the fileserver creates bitmaps for free vnodes on demand, allowing
5680 * If bosserver finds a BosConfig.new file at startup, it reads this file
5681 and renames it to BosConfig. This allows bosserver to be reconfigured
5684 * The bosserver can be placed in a restricted mode in which AFS
5685 superusers are only granted limited access to the server host. The
5686 following functionality is disabled when restricted mode is in use:
5689 bos getlog (except for files with no '/'s in their name)*
5695 specific exceptions are made for functionality that "bos salvage"
5698 A cron bnode who's name is "salvage-tmp", time is now, and command
5699 begins with "/usr/afs/bin/salvager" may be created. This bnode deletes
5700 itself when complete, so no special "delete" support is needed. This
5701 functionality may be removed in the future if a "Salvage" RPC is
5704 The file with the exact path /usr/afs/logs/SalvageLog may be fetched,
5705 since that is how bos salvage [...] -showlog is implimented.
5707 Restricted mode is enabled using a new bos command (bos setrestricted)
5708 or bossever command line switch (bosserver -restricted). Restricted
5709 mode can be disabled by a) sending the bosserver process a SIGFPE
5710 (which will then allow restricted operations until the next restart or
5711 setrestricted command) or b) editing /usr/afs/local/BosConfig (or
5712 BosConfig.new), and restarting the bosserver.
5714 * The bos UserList of trusted administrators can now contain cross-realm
5715 Kerberos principals.
5717 * udebug now takes --server not --servers.
5719 * Several error messages have been improved to include volume numbers.
5721 * Several new ports have been included for UNIX platforms: Darwin
5722 (ppc_darwin_12 and ppc_darwin_13), Linux 2.4 (i386_linux24), Linux on
5723 the Powerpc (ppc_linux22 and ppc_linux24), Linux on the Sparc
5724 (sparc_linux22, sparc64_linux22 and sparc64_linux24).
5726 * Incomplete FreeBSD and Alpha Linux ports are included. The FreeBSD
5727 port has a working server and the Alpha Linux port has a partially
5730 * A native client for Windows 95/98/ME has been added to the
5731 distribution. With this program, a gateway machine is no longer
5732 required for Windows 9x to access AFS files. One drive letter will be
5733 created on your machine by default - Z:. The Z: drive will be the
5734 root of the AFS tree, allowing you to browse all sites that have AFS
5735 servers available. Additional drive letters can be defined for other
5736 AFS directories. A Windows Explorer shell extension is included that
5737 allows you to right click on items within an AFS tree to bring up an
5738 "AFS" menu item and perform various operations on a file or directory.
5739 The most useful item is "Access Control Lists", which allows you to
5740 view and edit the permissions of a particular directory. Command line
5741 tools are also available in the install directory. These commands
5742 include klog, unlog, tokens, kpasswd, symlink, fs and pts. The
5743 installable includes a readme file that contains more information on
5744 how to use the client program and known issues.
5746 * Support for large caches in afsd. Cachefiles are stored in
5747 subdirectories. The default is 2048 files per subdirectory, which
5748 should work fine in most situations. You can use the new afsd option
5749 -files_per_subdir to change this number. Note that the first time you
5750 run afsd with this patch, your cachefiles will get moved into
5751 subdirectories. If you subsequently run an older version of afsd, you
5752 will lose all your cached files.
