1 User-Visible OpenAFS Changes
7 * Avoid a possible 100ms transmit delay in the RX protocol when a peer's
8 receive window transitions from closed to open (12627)
10 * Documentation improvements (12476 12477 12559[RT #133339])
14 * When bosserver is started with an unknown option, print an error message
15 and exit with a non-zero value rather than failing silently (12631)
17 All DB server platforms
19 * Hold the DB lock while checking for an aborted write transaction (12516)
21 All file server platforms
23 * On demand attach fileservers, don't save or restore a client's host
24 state if CPS ("Current Protection Subdomain") recalculation for it is
25 in progress, to avoid fileserver thread exhaustion (12568)
27 * On demand attach fileservers, avoid flooding the log with error messages,
28 which could happen when the fileserver was restarted while a volume was
31 * Update a volume's "Last Update" time when its content is modified by
32 the salvager, to make the change visible in the output of "vos examine"
33 and to backup services (12633)
37 * Corrected the DCentries bucket counts for very large and zero length
38 files in the output of "fs getcacheparms -excessive" (12604 12605)
40 * Fixed a bug that prevented users with GID 2748 and 2750 from executing
41 the "fs sysname" command on clients running afsd with -rmtsys (12607)
43 * Provide a new -inumcalc switch for afsd to allow enabling the alternative
44 MD5 method of inode number calculation, which was previously only
45 possible on Linux and through the sysctl interface (12608 12632)
49 * Support for mainline kernel 4.12 and distribution kernels with backports
52 * Re-added the improved algorithm for freeing unused vcaches to reduce
53 memory consumption first introduced with the 1.6.18 release, together
54 with a fix for the issue leading to its removal in 1.6.18.2 (12448..12451)
58 * Fixed a crash while stopping the client on macOS 10.12 "Sierra" (12602)
65 * Build fixes required by recent compilers or platforms (12514 12521 12534
68 * Allow the bos server to start successfully in the presence of those, by
69 accepting a now checked return value indicating that the client ThisCell
70 and CellServDB already exist (12522)
74 * Support for mainline kernels 4.10 and - most likely - 4.11 and
75 distribution kernels with backports from them (12530 12588..12590 12598)
77 * Support for distribution kernels with partial backports from 4.9 (12535)
80 * In Red Hat packaging, moved the klog.krb5 manual page into the krb5
83 * In Red Hat packaging, prevent systemd from double-starting the client
86 * Allow aklog to function on current S390/S390x (12499)
90 * Make process authentication groups work on Solaris 11, now using a single
91 group ID (12524..12527)
93 * Fix a BAD TRAP panic on Solaris 11 clients built with Studio 12.5 (12567)
97 * Fixed the preference pane for OS X 10.11 and later (12512)
103 * Build fixes required by recent compilers (12482..12484)
107 * Support for mainline kernel 4.9 and distribution kernels with
108 backports from it (12478..12480)
110 * In Red Hat packaging, make systemd deal correctly with the client
111 when no userland processes remain after starting it (12481)
116 * Support for release 10.12 "Sierra" (12431 12432)
118 * Avoid a crash in the Mounts tab of the OpenAFS preference pane (12447)
120 OpenAFS 1.6.20 (Security Release)
124 * Fix for OPENAFS-SA-2016-003: file and directory names leak due to
125 reuse of directory objects without zeroing the contents
126 (12461 12462 12463 12464 12465)
132 * Documentation improvements (12304)
133 * Fixes for test failures (12396 12415)
135 All DB server platforms
137 * Avoid potentially writing to an out of date volume location or protection
138 database, or losing a database write, which could happen in rare cases
139 under special conditions during database leader election
144 * Allow the fsinfo::: DTrace provider to work with AFS files (12371)
148 * Don't commit more data to a file than was actually copied during writes,
149 which could happen on architectures with a page size > 4 KiB (12413)
150 * Fixed build on PPC64 with GCC 6.1 (12388) (RT #133407)
151 * Fixed build on x86_64 with recent GCC (12365 12366)
158 * Support for mainline kernel 4.7 and distribution kernels with
159 backports from it (12348)
163 * Fixed memory mapped I/O on files >= 4 GiB (12349 12350)
165 Note that there is a suspicion that this might break the client
166 on very old Solaris releases (2.6). If it does, the breakage should
171 * Added tooling to build a package for OS X 10.10 "Yosemite" and
172 10.11 "El Capitan" (12335 12351)
179 * Support for mainline kernel 4.6 and distribution kernels with
180 backports from it (12332)
182 * Switch back to the pre-1.6.18 algorithm for freeing unused vcaches.
183 While the new algorithm is still believed to be correct, it turned
184 out that at least on some kernels, including 4.5 and 4.6, the dentry
185 for the current working directory may be erroneously invalidated.
186 This could lead to errors like "Unable to read current working directory"
187 when a directory wasn't accessed for a few minutes. (12323)
189 * Use a secure URL to retrieve the CellServDB in the script to create
190 the Red Hat source package (12330)
194 * Added sysname IDs for 10.2 and 10.3 to fix the build on those platforms
202 * Support for mainline kernel 4.5 and distribution kernels with
203 backports from it (12300..12302)
210 * Documentation improvements (12224 11675 11613 12197)
212 * Improved diagnostics and error messages (12129 12207 12185 12211 12113
215 * Check that CellServDB entries are valid IPv4 addresses, to avoid
216 occasional hangs or potentially other erratic behaviour due to invalid
217 entries (12210) (RT #131794)
221 * Gracefully handle cases where a client shutdown sequence is initiated
222 while the client is already shutting down, rather than cause a panic
225 * Fixed several bugs that could cause erratic behaviour when the write
226 offset into a file was more than 2 GiB beyond the file's current end
227 on the server (12213 12214)
231 * Avoid a possible volserver crash during volume dump or restore due
232 to invalid ACL entries (12127)
234 * Allow recovering from a DAFS fileserver operation which allocates a
235 new vnode but fails to update the vnode index, rather than crashing the
238 * Fixed a longstanding bug which could damage the volume location database
239 when "vos changeaddr" was run with "-oldaddr" and "-newaddr" and the
240 old address was present in a multi-homed entry (12089)
244 * Added support for releases 10.2 and 10.3 (12232)
248 * Support for mainline kernel 4.4 and distribution kernels with
249 backports from it, alas at a performance penalty (12226 12227 12228)
252 * Avoid using excessive amounts of kernel memory for dynamically
253 allocated vcaches, by improving the algorithm to free unused ones
256 * In Red Hat packaging, make the init script use "ip" if available, with
257 "ifconfig" as a fallback (12193)
261 * Basic support for release 10.11 "El Capitan" (12212)
265 * Fixed kernel module builds with optimization (12198) (RT #131261)
268 OpenAFS 1.6.17 (Security Release)
272 * Fix for OPENAFS-SA-2016-001: foreign users can create groups as
273 if they were an administrator (RT #132822) (CVE-2016-2860)
277 * Fix for OPENAFS-SA-2016-002: information leakage from sending
278 uninitialized memory over the network. Multiple call sites
279 were vulnerable, with potential for leaking both kernel and
280 userland stack data (RT #132847)
282 * Update to the GCO CellServDB update from 01 January 2016 (12188)
286 * Fix a crash when the root volume is not found and dynroot is not
287 in use, a regression introduced in 1.6.14.1 (12166)
289 * Avoid introducing a dependency on the kernel-devel package corresponding
290 to the currently running system while building the srpm (12195)
292 * Create systemd unit files with mode 0644 instead of 0755
299 * Documentation improvements (11932 12096 12100 12112 12120)
301 * Improved diagnostics and error messages (11586 11587)
303 * Distribute the contributor code of conduct with the stable release (12056)
307 * Create PID files in the right location when bosserver is started with
308 the "-pidfiles" argument and transarc paths are not being used (12086)
310 * Several fixes regarding volume dump creation and restore (11433 11553
313 * Avoid a reported bosserver crash, and potentially others, by replacing
314 fixed size buffers with dynamically allocated ones in some user handling
315 functions (11436) (RT #130719)
317 * Obey the "-toname" parameter in "vos clone" operations (11434)
319 * Avoid writing a loopback address into the server CellServDB - search
320 for a non-loopback one, and fail if none is found (12083 12105)
322 * Rebuild the vldb free list with "vldb_check -fix" (12084)
324 * Fixed and improved the "check_sysid" utility (12090)
326 * Fixed and improved the "prdb_check" utility (12101..04)
330 * Avoid a potential denial of service issue, by fixing a bug in pioctl
331 logic that allowed a local user to overrun a kernel buffer with a single
332 NUL byte (commit 2ef86372) (RT #132256) (CVE-2015-8312)
334 * Refuse to change multi-homed server entries with "vos changeaddr",
335 unless "-force" is given, to avoid corruption of those entries (12087)
337 * Provide a new vos subcommand "remaddrs" for removing server entries, to
338 replace the slightly confusing "vos changeaddr -remove" (12092 12094)
340 * Make "fs flushall" actually invalidate all cached data (11894)
342 * Prevent spurious call aborts due to erroneous idle timeouts (11594)
344 * Provide a "--disable-gtx" configure switch to avoid building and
345 installing libgtx and its header files as well as the depending
346 "scout" and "afsmonitor" applications (12095)
348 * Fixed building the gtx applications against newer ncurses (12125)
350 * Allow pioctls to work in environments where the syscall emulation
351 pseudo file is created in a read-only pseudo filesystem, like in
352 containers under recent versions of docker (12124)
356 * In Red Hat packaging, avoid following a symbolic link when writing
357 the client CellServDB, which could overwrite the server CellServDB,
358 by removing an existing symlink before writing the file (12081)
360 * In Red Hat packaging, avoid a conflict of openafs-debuginfo with
361 krb5-debuginfo by excluding our kpasswd executable from debuginfo
362 processing (12128) (RT #131771)
364 OpenAFS 1.6.15 (Security Release)
366 All client and server platforms
368 * Fix for OPENAFS-SA-2015-007 "Tattletale"
370 When constructing an Rx acknowledgment (ACK) packet, Andrew-derived
371 Rx implementations do not initialize three octets of data that are
372 padding in the C language structure and were inadvertently included
373 in the wire protocol (CVE-2015-7762). Additionally, OpenAFS Rx in
374 versions 1.5.75 through 1.5.78, 1.6.0 through 1.6.14, and 1.7.0
375 through 1.7.32 include a variable-length padding at the end of the
376 ACK packet, in an attempt to detect the path MTU, but only four octets
377 of the additional padding are initialized (CVE-2015-7763).
383 * Support kernels up to 4.2
385 Due to changes to internal data structures with this kernel release,
386 the OpenAFS client can no longer reset the link count during path
387 lookups. Since volume root directories must behave like symlinks
388 instead of normal directories in order to satisfy Linux kernel
389 invariants, looking up paths containing more than 40 mount points
390 will fail with ELOOP on such kernels.
396 * Prior to the OpenAFS security release 1.6.13, the Volume Location
397 Server (vlserver) RPC VL_ListAttributesN2() supported wildcard volume
398 name lookups via regular expression (regex) pattern matching. This
399 support was completely disabled in 1.6.13 because it was judged to be
400 a security risk due to buffer overruns in the implementation, as well
401 as the possibility of denial of service attacks where certain regular
402 expressions could cause excessive CPU usage in some regex
405 Unfortunately, after 1.6.13 was released, it was discovered that
406 the native OpenAFS 'backup' system uses the VL_ListAttributesN2()
407 regex support to evaluate configured volume sets. If you use the
408 OpenAFS 'backup' system (or another backup system which relies on it,
409 such as Tivoli Storage Manager (TSM, aka Tivoli ADSM)), and are using
410 volume sets which require regular expressions for the volume name,
411 then those volume sets cannot be resolved by OpenAFS 1.6.13. The next
412 paragraph provides details on how to identify any affected volume sets.
414 OpenAFS backup volume sets may be described by fileserver, partition
415 name, and volume name. The fileserver and partition specifications
416 never require regular expression support. The volume name specification
417 always requires regular expression support except for when specifying
418 _all_ volumes via two special cases: the universal wildcard ".*", or "".
419 For example, volume name "proj" or "*.backup" or "homevol.*" all
420 require regex support - even if the specification contains no wildcard
421 characters and/or exactly matches an existing volume name.
423 As a result of this issue, OpenAFS 1.6.14 replaces the 1.6.13 changes
424 to VL_ListAttributesN2. 1.6.14 prevents the buffer overruns and
425 reenables the regex support, but restricts it to OpenAFS super-users
426 and -localauth only. This is sufficient to restore the OpenAFS 'backup'
427 system's ability to work correctly with any previously supported volume
428 set. The OpenAFS 'backup' commands are already documented to require
429 super-user authorization, so this restriction is moot for the backup
432 There are no other direct consumers of the VL_ListAttributesN2() regex
433 support in the OpenAFS tree. However, the VL_ListAttributesN2 RPC is
434 publicly accessible and might be used by third party tools directly or
435 indirectly via OpenAFS's libadmin. Any such tools that issue
436 VL_ListAttributesN2 RPCs must now be executed using super-user or
439 None of the other security fixes in OpenAFS 1.6.13 are known to have
440 any issues, and are still included unchanged in OpenAFS 1.6.14.
442 If there are any questions concerning the possible impact of OpenAFS
443 1.6.13 or 1.6.14 at your site, please contact your OpenAFS support
444 provider or the openafs-info@openafs.org mailing list for further
451 * Fix for CVE-2015-3282: vos leaks stack data onto the wire in the
452 clear when creating vldb entries
454 * Workaround for CVE-2015-3283: bos commands can be spoofed, including
455 some which alter server state
457 * Disabled searching the VLDB by volume name regular expression to avoid
458 possible buffer overruns in the volume location server
462 * Fix for CVE-2015-3284: pioctls leak kernel memory
464 * Fix for CVE-2015-3285: kernel pioctl support for OSD command passing
469 * Fix for CVE-2015-3286: Solaris grouplist modifications for PAGs can
470 panic or overwrite memory
476 * Avoid database corruption if a database server is shut down and then
477 brought up again quickly with an altered database (11773 11774)
482 * Fixed a potential buffer overflow in aklog (11808)
484 * Avoid a bogus warning regarding the checkserver daemon, which could be
485 logged during startup when the cache initialization was very fast (11680)
487 * Added documentation of the inaccuracy of the 'partition' field in
488 'fs listquota' output for partitions larger than 2 TiB (11626)
492 * Support kernels up to 4.1 (11872 11873)
494 * Avoid spurious EIO errors when writing large chunks of data to
495 mmapped files (11877)
499 * Build fixes required at least on OS X 10.10 Yosemite with the latest
500 XCode (11859 11876 11842..11845 11863 11878 11879)
506 * Support kernels up to 4.0 (11760 11761)
510 * Fixed kernel module build on systems with an updated clang which no
511 longer accepts the -mno-align-long-strings as a no-op (11809)
517 * Allow aklog to succeed creating native K5 tokens even when mapping
518 the K5 principal to a K4 one fails (11538)
520 * Build fixes (11435 11636)
524 * Avoid a potential kernel panic due to connection reference overcounts
527 * Avoid potential corruption of files written using memory mapped I/O
528 when the file is larger than the cache (11656) (RT #131976)
532 * Support kernels at least up to 3.19 (11549 11550 11569 11570 11595
533 11658..11662 11694 11752)
535 Note: By default this excludes kernels 3.17 to 3.17.2, which will leak
536 an inode reference when an error occurs in d_splice_alias(). The
537 module will build and work, but leak kernel memory, leading to
538 performance degradation and eventually system failure due to
539 memory exhaustion. Since it's impossible to detect this condition
540 automatically, the switch --enable-linux-d_splice_alias-extra-iput
541 must be passed to configure when building the module for those
542 kernels. The same would be necessary for any kernel with backports
543 of commit 908790fa3b779d37365e6b28e3aa0f6e833020c3 or commit
544 95ad5c291313b66a98a44dc92b57e0b37c1dd589 but not the fix in commit
545 51486b900ee92856b977eacfc5bfbe6565028070 in the linux-stable repo
546 (git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git) or
547 the corresponding changes on other branches.
549 * Fixed a regression introduced in OpenAFS release 1.6.10 which could
550 make the spurious "getcwd: cannot access parent directories" problem
551 return (11558 11568) (RT #131780)
553 * Avoid leaking memory when scanning a corrupt directory (11707)
557 * Support OS X 10.10 "Yosemite" (11571 11572 11611) (RT #131946)
561 * Avoid reading random data rather than correct cache content when using
562 ZFS as the cache file system on Solaris >= 11, and fix potential similar
563 problems on other platforms (11713 11714)
567 * Build fix for releases >= 11.0 (11610)
571 * Support release 5.4 (11700)
578 * Don't hide the "version" subcommand in help output (11214)
580 * Documentation improvements (11126 11216 11222 11223 11225 11226)
582 * Improved diagnostics and error messages (11154 11246 11247 11249 11181
585 * Build system improvements (11158 11221 11224 11225 11227..11241 11282
586 11342 11350 11353 11242 11367 11392)
588 * Avoid potentially erratic behaviour under certain error conditions by
589 either avoiding or at least not ignoring them, in various places (11008
590 11010..11065 11112 11148 11196 11530)
594 * Support releases 9.3 and 10.1 (11368 11369 11402 11403 11404)
596 * Makes a disk cache more likely to work on FreeBSD, though such
597 configurations remain not very tested (11448)
601 * Added volscan(8) (11252..11280 11387 11388)
603 * Fixed a bug causing subgroups not to function correctly if their
604 ptdb entry had more than one continuation entry (11352)
606 * Logging improvements (10946 11153)
608 * Allow log rotation via copy and truncate (11193)
610 * Avoid a server crash during startup only observed on a single platform
611 and when using a 3rd party library under certain circumstances, which is
612 a collateral effect of the security improvements introduced in OpenAFS
613 release 1.6.5 (11075) (RT #131852)
617 * Raised the free space reported for /afs to the maximum possible value of
618 just under 2 TiB - the old value was 9 GiB on most platforms (10984)
620 * Reduced the amount of stack space used (11162 11163 11203 11164..11167
621 11338 11339 11364..11366 11381)
623 * Sped up a periodic client task which could be problematically slow
624 on systems with a large number of PAGs and files in use (11307)
626 * Fixed failure of the up command with large ACLs (11111)
628 * Avoid a potential crash of aklog (11218)
630 * Avoid potential crashes of scout and xstat_fs_test (11155)
634 * Support kernels up to 3.16 (11308 11309)
636 * Fixed a regression introduced in OpenAFS release 1.6.6 that made
637 checking for existing write locks incorrectly fail on readonly volumes
640 * Fixed a regression introduced in OpenAFS release 1.6.8 that could
641 cause VFS cache inconsistencies when a previously-accessed directory
642 entry was removed and recreated with the same name but pointing to a
643 different file on another client (11358)
645 * Use the right path to depmod in Red Hat packaging to avoid dependency
646 calculation incorrectly failing unless a link /sbin -> /usr/sbin is
647 present on the system performing it (11171) (RT #131860)
649 * Do not ignore kernel module build errors (11205)
655 * Fix for OPENAFS-SA-2014-002

663 * Improved diagnostics and error messages (10756 10814 10949)
665 * Fixed a bug in RX that could make errors during packet reception go
668 * Fixed a bug that made "vos size -dump" display the wrong size for
669 large volumes. (10933) (RT #131819)
673 * Change the default fileserver sync behavior from "delayed" to "onclose".
674 This means that explicit syncing only happens when a volume is detached.
677 * Added the -offline-timeout and -offline-shutdown-timeout options to the
678 fileserver, to implement interrupting clients accessing volumes we are
679 trying to take offline. (6266 10799)
683 * When a client is shut down, it will give up its callbacks. The Windows
684 client has been doing this since 2007. Note that older fileservers
685 (1.3.50 to 1.4.5 and 1.5.0 to 1.5.27) had a bug in the implementation of
686 the relevant RPC that could cause crashes or other undefined behavior
687 when this happens. (6272 8840 10855)
689 * Restored the pre-1.6 behavior of "vos e" being an alias for "vos examine".
692 * Avoid flooding logs with warnings about byte-range locks, by throttling
693 them per file. Also, make the messages more useful by including the
696 * Avoid a possible panic during shutdown while tracing. (10932)
700 * Fixed a bug that could cause the "getcwd: cannot access parent
701 directories" problem (10804 10984)
703 * Avoid a delay when accessing uncached data in AFS in a confined
704 context under SELinux. (10598)
706 * Red Hat packaging improvements (10600 10767 10807)
712 * Fix for OPENAFS-SA-2014-001
714 * Fix for a potential DOS attack against RX servers
720 * As of this release, OpenAFS no longer ships uncompressed source tarballs.
721 Tarballs are still shipped with both compression formats, gzip and bzip2.
724 * Documentation improvements (10136 10314 10601)
726 * Improved diagnostics and error messages (9412 10085 10274)
728 * Avoid redefining "assert" in our public header files, which could
729 cause failures when building some applications using them. (10096)
731 * Fixes for parallel builds (10005 10309 10337)
733 * Added a -s switch to afscp (not installed by default) to help simulate
734 a slow client. (9416 9417)
736 * Added a -probe switch to vlclient test program (not installed by default)
737 to ping all vlservers in a cell in parallel. (9570)
740 * The fileserver now ignores any vice partitions with a NeverAttach flag
741 file present in the root directory. (RT #130561) (9470 9471)
743 * Restrict forcing CPS ("Current Protection Subdomain") recalculation in
744 the fileserver to administrators. Also fixed a bug that could cause this
745 operation to be incomplete. (9485 9487)
747 * Allow non-DAFS fileservers to attach unusable volumes, restoring pre-1.6
748 behaviour. (RT #131505) (9499)
750 * Restored the pre-1.6 behaviour when running vos examine for a volume
751 currently in a transaction, showing the volume as busy again rather than
752 offline. (9685 9915 9916)
754 * Reduced the minimum time a bos salvage takes from 5 seconds to 1. (9476)
756 * Fixed buserver to not segfault when started with the -servers option.
759 * Salvager fixes, addressing a wide variety of possible problems from
760 unnecessary salvaging to aborts (9282 9283 9457 9458 9459 9461 9462 9480
763 * Fixed a bug that could cause saved state information to be discarded
764 when restarting a large or busy fileserver, which negatively impacted
767 * Fixed a bug that could have caused undefined behaviour in the vlserver
768 in rare cases when a fileserver registered its addresses in the VLDB.
771 * Added the -preserve-vol-stats switch to volserver, allowing it to keep
772 the access statistics across volume restore and reclone operations
773 instead of resetting them. (9477)
775 * Inserted an exponential delay between retries when bosserver attempts to
776 restart a server process. (9571 10199)
778 * Improved vldb_check (not installed by default) to cope with broken
779 vlentry names and volids, and provide more output to aid debugging.
782 * Releasing a volume after adding a new RO site no longer touches any of
783 the existing RO sites, if the RW data hasn't changed since the last
786 * Make the copyDate field for RO clones have the same meaning as for
787 remote RO volumes. Previously, the copyDate field for clones was updated
788 every time we released. (9451)
790 * Fixed potentially undefined behaviour in ptserver when too many pts
791 ids are allocated. (10124)
793 * Note that the server side NAT pings feature present in the prereleases
794 was removed before the final release, since no positive feedback
795 was provided during prerelease testing. (9420 10135)
799 * Start bosserver with -nofork in the systemd unit file, to allow systemd
800 to track its state (10093)
804 * No longer track file locks on read-only volumes. Write locks can't
805 succeed, read locks always will. Avoids log messages about this kind
808 * Added the "fs flushall" subcommand, which makes the client discard all
809 cached data. This was previously available on Windows only. (9065 9388
812 * Fixed a bug that could make the client incorrectly believe its cache
813 is up to date. This change could negatively impact AFS <-> DFS
814 translators, should those still be running anywhere. (8898)
816 * Several changes to avoid panicing in certain error conditions.
817 (9131 9287 10354 10355 10356 10357) (partially addressing RT #131747)
819 * Added the -rxmaxfrags switch to afsd, allowing to limit the number
820 of UDP fragments sent or received per RX packet. (9430)
822 * Build fixes for aklog on several platforms (RT #131716) (9917 10107 10275)
824 * Require that the AFS mountpoint specified in the cacheinfo file is
825 an absolute path. Relative paths result in a client that basically
826 works but is not fully functional. (10253)
828 * Fixed a bug that could cause one of the afsd threads to enter an infinite
829 loop (10431 .. 10436)
833 * Support Linux kernels up to 3.13 (10241)
835 * Fixed a bug that made readv/writev calls in AFS space fail with Linux
836 kernels where generic_file_aio_read exists but those operations have
837 not been switched to using aio_read/aio_write. This was a regression
838 introduced with release 1.6.3 and affected at least RHEL 5.9 kernels.
841 * Fixed a similar bug making core dumps fail in AFS space, affecting
842 a much wider range of kernels including the most recent ones.
845 * Enhanced the keyring code to make PAGs work correctly on kernels with a
846 distribution specific change to the Linux keyring code. This affected at
847 least SLES 11 SP3 kernels. (10252)
849 * Fixed a bug that could make failures during PAG instantiation go
852 * Fixed a bug that made compilation fail for Linux kernels without
853 keyring support. This affected at least the SLE 10 SDK and an
854 OEM version of SLES 11 SP1. (10325)
856 * Fixed build for kernels with user namespace support enabled. Likely
857 to be required for Ubuntu 14.04 and eventually other distributions.
858 (10456 10457 10458 10518 10472)
860 * Support RHEL 6.5 kernels, and possibly others with changes backported
861 from recent mainline kernels that touch getname/putname, by no longer
862 using those functions. Previously, the client could cause a kernel
863 panic when syscall auditing was enabled. (10578)
865 * Make tmpfs usable as the cache filesystem again. This had been broken
866 since kernel 3.1 (9950 10193)
868 * When starting the client fails, clean up the backing device information
869 created in sysfs, to avoid error messages during a subsequent start
870 and possible system instability later on (10454)
872 * Update Red Hat packaging to support Fedora >= 20, RHEL >= 7 and
873 ELrepo kernels (10597 10619 10622 10703 10704)
877 * Support OS X 10.9 "Mavericks" (10519 10541 10542 10543 10548 10549)
881 * Fixed a bug that caused the 1.6 AIX client to never receive any RX
882 packets in the kernel. (RT #131725)
886 * Support Solaris 11 (9454 9455)
888 * Allow other users to access filesystems mounted by root. (9452)
892 * Build tvolser and dvolser on this platform (10122)
893 * Several fixes to catch up with newer releases (10374 .. 10381)
897 * Build tsalvaged, tvolser and dvolser on this platform (10121)
898 * Fixed build on NetBSD 5 and newer. (10138)
904 * Fixes for OpenAFS-SA-2013-0003 and OpenAFS-SA-2013-0004
910 * Obey the jumbo/nojumbo settings for ubik servers (the DB servers)
911 too. In previous releases, those servers may have used jumbograms
912 even if they were not configured to do so. This change corrects
913 the actual behaviour, and will improve performance and reliability
914 for sites where jumbograms are problematic. It could cause a decrease
915 in performance for sites where jumbograms work, but those can turn
916 them back on manually.
918 * Dozens of fixes for common coding problems like use after free,
919 use of possibly uninitialised memory, reading or writing past the
920 end of arrays and potential NULL pointer derefences. Spotted by
921 code analysis tools or human inspection.
923 * Documentation improvements.
925 * Fixes and improvements to the diagnostic or log messages printed by
926 vos, the fileserver and others.
928 * Build fixes, making parallel builds more reliable with certain
929 configuration options and helping various platforms including
930 recent releases of IRIX, Solaris and several flavours of Linux.
932 * Avoid sending a small amount of data over the wire unencrypted
933 under certain conditions, and emit the correct error message in
938 * Avoid generating duplicate IDs for readonly and backup volumes,
939 which could happen under certain conditions.
941 * Allow the fileserver to return volume data like quota or free space,
942 which is available publicly elsewhere, without the additional access
943 check for read permissions on a volume's root directory the fileserver
946 * The fileserver now emits a log message when it ran out of memory for
949 * Avoid several potential fileserver problems, including memory
950 corruption and segmentation faults, due to client bookkeeping.
952 * Avoid known cases of silent data corruption due to background syncs
953 on the fileserver, especially during Copy on Write.
955 * Make the fileserver sync behaviour runtime configurable. Up to 1.4.5,
956 we had synchronous syncs which were safe but really slow. Since 1.4.5,
957 we've had asynchronous syncs which are much faster but believed to
958 be the cause of rare data corruption issues, and while all known cases
959 of these happening are believed to be fixed in the 1.6.3 release, doubts
960 remain. This change allows choosing between those, and in addition allows
961 to turn syncs by the fileserver off altogether, thus relying on the vice
962 partition's backend filesystem and the operating system, or to just
963 execute them when a volume is detached. The default behaviour is
964 unchanged from releases since 1.4.5, but it's highly recommended to
965 consider the additional options this change provides. Future OpenAFS
966 releases will default to "-sync=none".
968 * For dbservers, avoid a situation where misinterpreting transient
969 network errors causes long-term issues with achieving ubik quorum.
971 All UNIX client platforms
973 * Improvements to the detection of an aklog-specific krb5 configuration
974 file, for the purposes of turning on "weak crypto" for aklog.
976 * Fixed a regression introduced in release 1.6.2 which caused the
977 supposedly persistent disk cache to be discarded upon client start.
982 * Support Linux kernels up to 3.10
984 * Fixed two bugs making it impossible to unmount a disk cache filesystem
985 after it has been used by the client. (RT #131613)
987 * Fixed a bug that could cause an oops with kernels 3.6 and later
991 * Improved support for OpenBSD 4.9 to 5.3
995 This release number had to be skipped for technical reasons.
1001 * Support Linux kernels up to 3.8.
1003 * Make the init script cope with the output of ifconfig on recent Fedora.
1009 * Fix buffer overflows in fileserver and ptserver.
1011 * Abort an rx connection when given an unknown service (Gerrit 7593).
1013 * "idle dead" behavior improvements.
1015 * Documentation updates.
1017 All server platforms
1019 * Fix rare file corruption during background sync (Gerrit 8796).
1021 * Fix corrupting clients' metadata cache during certain errors (Gerrit
1024 * Avoid saying a volume doesn't exist when accessed as the volume is
1025 going offline (Gerrit 7488).
1027 * Fix fileservers to properly report >2 TiB partitions.
1029 * Fix stale volume info from vos examine on non-DAFS filservers.
1031 * Fix possible volume corruption with vos convertROtoRW.
1033 * Fix bosserver to preserve all command-line options over restart.
1035 * Fix bosserver to properly kill hung processes during shutdown.
1037 All UNIX client platforms
1039 * Fixes for memcache, especially on Solaris.
1041 * Increase the size of the DNS resolver answer buffer to allow sites
1042 with a long response list to use SRV and AFSDB records.
1044 * Fix a crash when a server appears to run out of addresses (Gerrit
1047 * Fix cache corruption when reading from a file another client is
1048 simultaneously writing to (Gerrit 7994).
1050 * Improve handling of disk cache disk errors.
1054 * fix DKMS configuration for DKMS 2.2.
1056 * Avoid generating inode number 0 with md5 inodes (Gerrit 7276).
1058 * Fix a crash when reading /proc/fs/openafs/unixusers (Gerrit 7914).
1060 * Make PAG-less access use the real UID of the calling process
1061 instead of the effective UID, when determining what credentials to
1064 * Fix possible abuse of fs mkmount.
1065 Prior to 1.6.2, users could crash a client by nesting volume mounts.
1067 * Fix fileserver memory corruption on RHEL 6
1068 Prior to 1.6.2, fileservers on RHEL 6 may crash under heavy load.
1070 * Fix client page cache corruption on Linux
1071 When multiple clients read and write to a file, the reading client
1072 may see first page (4096 bytes) of a file as nulls.
1074 * Support Linux kernels up to 3.7.
1076 * Support newer glibc versions.
1078 * Improve client systemd unit file.
1080 * Update Red Hat packaging.
1084 * Fix crashes on shutdown.

1088 * Security improvement for the OpenAFS preference pane.
1092 * Support newer versions of the Sun Studio compiler software.
1094 * Support compiling on newer versions of Solaris 11 and Solaris 10.
1097 OpenAFS 1.6.0 (2011-08-15)
1101 * Substantial Rx updates to correct erroneous behavior.
1103 * vos now properly deals with matching sites when servers are
1106 * Don't stop Rx keepalives after an ackall is received, avoiding
1107 spurious connection timeouts. (128848)
1109 * Don't retry Rx calls on channels returning busy errors and improve
1110 Rx busy call channel error handling. (128671)
1112 * Properly enable Rx connection hard timeouts.
1114 * Rx NAT pings are not enabled until peer has answered.
1116 * Initialize rx_multi lock before use.
1118 * Avoid spurious crashes when initializing in "backup" client.
1120 * Revert UUID support in vos.
1122 * pt_util fixed to properly create new databases.
1124 * MTU discovery now properly shut down on call reset.
1126 * Avoid leaking references to hosts during callback break multi-Rx
1127 operations. (129376)
1129 * xstat tools now cope with differing timeval structures between
1132 * Numerous fixes to command argument parsing.
1134 * Documentation updates.
1136 All server platforms
1138 * A file descriptor leak which could result in corrupted files in the
1139 fileserver was fixed. An IMMEDIATE upgrade from previous 1.5 release
1140 fileservers is recommended.
1142 * Fix ptserver supergroups support on 64 bit platforms.
1144 * Demand attach salvaging doesn't use freed volume pointers.
1146 * Properly hold host lock during host enumeration in fileserver.
1148 * Attempt to recovery more quickly from timed out volume release
1151 * Auditing now properly byte order swaps IP addresses when printing.
1153 * vos split now has improved error handling.
1155 * Many changes to again support Windows fileservers.
1157 * During volume removal, data removal speed improved.
1159 * Improve CPU utilization during volume attaching by DAFS.

1163 * Fix support for large (greater than 2gb) volume special files.
1165 * Salvager will not crash if multiple or bad volume link tables are
1168 * Avoid erroneous full dump by remembering which sites were out of
1169 date at the start of the release.
1171 * A deleted volume can now be recreated properly.
1173 * Callbacks are again not broken during whole partition salvages.
1175 * Positional vectored IO fixed for largefile (>2GB) capable systems.
1177 * Fileserver per-client thread usage again properly enforced.
1179 * Anonymous dropbox support improved and drawbacks documented.
1181 * Demand attach: ensure vnodes are not reallocated while in use due to
1182 volume bitmap errors.
1184 * Properly support large volume numbers (larger than 2147483647).
1186 * Allow salvager to be run manually again when DAFS is being
1189 * Avoid leaking references to hosts during callback break multi-Rx
1190 operations. (129376)
1192 * Demand attach: unlink fileserver state file on standalone salvage.
1194 * Salvager tries harder to detect linktable issues.
1196 * Demand attach: don't attach volumes with special status set.
1198 * Avoid crashing on host table exhaustion. Instead, defer clients.
1202 * afs_config will not longer set the Tray Icon State in the registry
1203 if the checkbox is not present in the dialog. (128591)
1205 * AFS Explorer Shell Extension now works from folder backgrounds.
1206 Overlays for mount points and symlinks are present in the dll, but
1207 are not registered at present by the installers.
1209 * Do not use RankServerInterval registry value as the value for
1210 PerformanceTuningInterval.
1212 * When the data version of a mountpoint or symlink changes, the target
1213 string in the cm_scache_t object must be cleared.
1215 * "fs checkservers" now includes vldb servers in the output and only
1216 lists multi-homed servers once. A multi-homed server that has at
1217 least one up interface is no longer considered to be down.
1219 * When asynchronously storing dirty data buffers to the file server
1220 ensure that (a) the cm_scache_t object and the cm_buf_t object are
1221 for the same File ID so that locking and signalling work properly;
1222 and (b) if the FID no longer exists on the file server, do not
1223 panic, just discard the buffer.
1225 * When processing VNOVOL, VMOVED and VOFFLINE errors perform server
1226 comparisons by UUID or address and not simply by cm_server_t
1227 pointer. Otherwise, server failover may not succeed.
1229 * Do not preserve status information for cm_scache_t objects when the
1230 issuing server is multi-homed.
1232 * Giving up all callbacks when shutting down or suspending the machine
1233 is now significantly faster due to the use of an rx_multi
1234 implementation. (This functionality is still off by default and
1235 must be activated by a registry value.)
1237 * Race conditions were possible when updating the state of the
1238 cm_volume_t flags and when moving the volumes within the least
1241 * Ensure that the lanahelper library does not perform a NCBRESET of
1242 each lan adapter when enumerating the current network bindings.
1243 Correcting this permits OpenAFS to work on Windows 7 when the
1244 network adapter settings change.
1246 * Fix creation of mount points and symlinks as \\AFS\xxxx
1248 * Icon tray state now conditionally set. (128591)
1250 * Properly create new cell mount points in freelance mode.
1252 * Avoid recursive offline volume checks.
1254 * Fix caching of non-existent volumes. The test to trigger an
1255 immediate CM_ERROR_NOSUCHVOLUME in cm_UpdateVolumeLocation() was
1258 * Prevent the background daemon from checking the status of
1259 non-existent volumes. cm_CheckOfflineVolumes() should skip volume
1260 groups with the CM_VOLUMEFLAG_NOEXIST flag set.
1262 * The afskfw library should return an error immediately if the
1263 krb5_32.dll library cannot be loaded. Affects afslogon.dll and
1266 * No longer depend on leashw32.dll in afskfw library.
1268 * NPLogonNotify must provide the user password in all calls to
1269 KFW_AFS_get_cred(). It cannot count on a credential cache being
1270 preserved between calls. Permits tokens to be acquired for all
1271 cells listed in the TheseCells registry value for a domain.
1273 * Improve the trace logging from NPLogonNotify().
1275 * Avoid a race when writing the cm_scache_t mountPointString
1276 when acquiring mount point or symlink target data via
1277 cm_GetData(). The race could result in bogus target
1280 * Permit the use of des-cbc-md5 and des-cbc-md4 enctypes
1281 as DES keys in asetkey.exe.
1283 * aklog supports dotted Kerberos v5 principal names.
1285 * afskfw library always attempts afs/cell@USER-REALM
1287 * afskfw library must test return code from krb5_cc_start_seq_get() or
1288 will trigger a null pointer exception when using Heimdal.
1290 * Lock protected fields must be 32-bit in order to avoid memory
1293 * Add support for NTFS symlinks.
1295 * Handle file search requests for virtual syscall ioctl file.
1297 * Process SyncOps properly to enforce ordered operations.
1299 * Avoid recursing during NewServer operations.
1301 * Correct lock acquisition order during SMB locking.
1303 * Add shutdown message to event log.
1305 * Check offline volume status by policy rather than on each daemon
1308 * Return error on directory object not found instead of crashing.
1310 * Improve error message output.
1312 * afslogin.dll can start afsd_service if it's not starting or started.
1314 * Optimize away release lock RPCs for deleted files.
1316 * Background Daemon will not perform operations on deleted files.
1318 * Resort recently used directories to the top of the LRU if the
1319 directory is larger than the stat cache.
1321 * Resort deleted objects to the bottom of the LRU.
1323 * Use interlocked operations for state and queue fields to allow safe
1324 bit set and clear on multiprocessor systems.
1326 All UNIX client platforms
1328 * Servers now marked down when GetCapabilities returns error.
1330 * In-use vcache count is now properly tracked.
1332 * Check for /afs existance before starting, unless -nomount is
1335 * Avoid a potential panic when using /afs/.:mount syntax.
1337 * Avoid a panic in memcache mode due to missing CellItems file.
1339 * FUSE client support fixed for non-/afs mounts.
1341 * Avoid a potential deadlock (which times out) when we need to
1342 allocate more callback returns and must flush some already in use.
1344 * Deal with libcom_err conflicts with other packages using it
1345 (e.g. krb5) (128640)
1347 * Fall back to afs3-vlserver SRV record values when afs3-ptserver SRV
1348 record is not available.
1350 * Avoid holding unneeded locks when probing server capabilties.
1352 * Do not attempt page flushes for directories.
1354 * Rx connection reference counting is enabled.
1356 * An Rx connection reference count leak is fixed in bulkstat.
1358 * Handle unparsable directory objects.
1360 * Handle Kerberos cred cache errors in aklog.
1364 * Fix PAG usage to track by PAG identifier, not group list.
1368 * Fix socket termination on shutdown.
1370 * Support for 7.2, 7.3, 7.4 and 8.2 included.
1372 * References to vcaches are no longer leaked during root or reclaim.
1374 * Remove support for "Giant" lock as we no longer need to use it.
1376 * Don't sleep with AFS GLOCK.
1378 * Properly enable 64 bit long long support.
1380 * Restore support for FreeBSD 7 (128612)
1382 * Fix locking issues at shutdown and avoid panic at shutdown due to
1385 * Support for virtual network stacks.
1387 * New RC script, updated packaging.
1391 * Properly create new vnodes to avoid crashing in the client.
1395 * Support through kernel 2.6.39. Treat Linux 3.0 as Linux 2.6 for
1398 * Use rx_Readv in cache bypass to improve performance.
1400 * Properly handle 0-length replies during cache bypass operations.
1402 * Properly handle non-contiguous readpage cache bypass operations.
1404 * Do proper locking when transitioning to or from cache bypass.
1406 * Avoid extra runs of vcache freeing routine. (128756)
1408 * Perform vcache eviction via a fast path before visiting vcaches
1409 where sleep is needed.
1411 * setpag() errors are now properly reported.
1413 * Avoid attempting to free stat cache entries when we are below
1414 user-specified number of entries in use.
1416 * Properly track user-specified number of stat cache entries to use as
1417 a desired usage target.
1419 * Don't read pages beyond EOF in the cache. (128452)
1421 * Various corrections and improvements to Red Hat packaging, including
1422 modifying the init script to allow deferring for a new binary
1423 restart and properly supporting RHEL6.
1425 * Fix lockup in 2.6.38 due to erroneous kernel feature configure test.
1427 * Improve RPM building tools.
1429 * Attempt to properly handle SELinux in packaging.
1431 * Init script properly returns status as exit code.
1433 * RPM packaging fixes (executable libraries, no postinstall message)
1435 * Kill i386 from RPM packaging.
1439 * MacOS 10.7 support.
1441 * Properly handle setpag errors. PAGs are not supported.
1443 * Check for unloaded kernel extensions when decoding AFS panics.
1445 * Disable "get tokens at login" in prefs pane if AD authentication
1446 plugin is configured.
1448 * aklog AuthorizationPlugin now provided.
1450 * Preferences Pane behavior fixed for 1.6 series (version detection is
1451 used to select default behavior).
1453 * A potential kernel panic during bulkstat operations is
1456 * 64-bit MacOS kernel performance is greatly improved. (128934)
1458 * Properly shut down AFS, closing the Rx socket in the upcall handler
1459 to avoid attempting to process data after we can no longer do so.
1461 * Rework logic for bulk status operations to avoid a potential hang.
1463 * Avoid panic when doing FSEvent synthesis.
1465 * Fix bug when using non-dynroot.
1467 * Update Kerberos support in PreferencesPane.
1471 * Updates for platform support.

2496 * Adjust SMB error return codes to avoid returning STATUS_TIMEOUT
2497 which results in the SMB redirector disconnecting.
2499 * Network Identity Manager OpenAFS Provider now provides its own "AFS
2500 lock" notification icon to report the status of "have tokens, have
2501 no tokens, service not started, service started but inaccessible".
2502 Hovering over the icon lists the cells for which tokens exist (if
2503 any) and the OpenAFS version number. Double-clicking executes the
2504 Network Identity Manager default action.
2506 * Prevent pioctl calls from retrying indefinitely when a sharing
2507 violation error occurs.
2509 All UNIX client platforms
2511 * Correct a condition which could discard the error from initializing
2514 * Avoid using invalid references to afs_Conn connection structures,
2515 and thus potentially producing invalid data when a retry is needed.
2517 * SRV records are now supported for discovering AFS servers.
2521 * Correct writepage behavior.
2523 * Fix error code handling in the writepage code.
2525 * Avoid leaking page locks, which could potentially hang a machine.
2529 * Preferences Pane improvements.
2533 * Avoiding attempting to handle critical signals in servers, so that
2534 core file handling works correctly.
2537 OpenAFS 1.5.65 (2009-10-06)
2541 * Code compilation warning fixes, to enable better finding and
2544 * Provide configure-time switch to enable code warning compilation.
2546 All server platforms
2548 * Demand-attach fileserver now makes volume LRU list operations
2549 exclusive operations to avoid races during adding to the list.
2551 * Fileservers now avoid potential "negative length" fetches.
2553 * A leak in host tracking objects in the fileserver has been fixed.
2555 * Salvager now unlinks all files by full path, to deal with the change
2556 to not chdir for core file tracking.
2558 * Salvager avoids asserting if the volume header is unreadable.
2560 * Demand-attach fileserver puts back volume references from fssync
2565 * Improved service response to suspend and shutdown event
2568 * Avoid a bug in the file server that can result in an invalid length
2569 being returned as part of a fetch data response if the client
2570 attempts to read beyond the length of the file.
2572 * Do not publish a default stream object for directories and mount
2573 point objects. This was impacting the ability of some Windows XP
2574 systems to save roaming profiles.
2576 All UNIX client platforms
2578 * A bug which could cause erroneous handling of lengths on data reads
2581 * A bug where erroneous length returns from the fileserver could
2582 result in a false error has been fixed.
2586 * Background page copies are now supported for enhanced disk cache
2589 * Blocking readahead is supported in readpages() to reduce overhead.
2591 * Use readpage() instead of read() to access cache data to avail disk
2592 cache users of the kernel backing cache for improved performance.
2594 * Minimize credential handling for improved performance.
2598 * Preferences Pane cleanup.
2602 * Provide a fs_pathconf method with sensible defaults.
2604 * Provide a _PC_FILESIZEBITS method to fix some NFS translator
2608 OpenAFS 1.5.64 (2009-09-22)
2610 All server platforms
2612 * The demand attach fileserver now puts back volume references gotten
2613 via the fssync interface.
2615 * The demand attach fileserver had a structure reference error, which
2616 has been correected.
2620 * Restores Windows 2000 compatibility.
2622 * Fixes a data consistency error between the output of NetWkstaGetInfo
2623 and NetServerGetInfo RPCs, specify the Lan workstation group name
2624 "AFS", and report server name as "AFS" instead of "\\AFS" when the
2625 caller asks for "\\AFS".
2627 * Enables executables to be run from \\AFS on Windows 7. Returns
2628 "Name not found" instead of "File not found" when a directory or
2629 file name cannot be found. This avoids loader errors when system
2630 dlls cannot be located in the executable directory.
2632 * Prevents cache manager from marking the file server "down" when the
2633 data returned in response to either RXAFS_FetchData64 or
2634 RXAFS_StoreData64 is invalid.
2636 * Adds pioctl data validation to the AFS Explorer Shell extension.
2638 All UNIX client platforms
2640 * A bug which could cause a kernel panic in 1.5.63 has been corrected.
2641 This would manifest as a GetDCache panic or oops.
2645 * aklog -setpag works again with recent kernels when keyring is in
2650 * When Fast User Switch is in use, AFS login is now handled correctly
2651 by the integration tool included with the preferences pane.
2653 * Several packaging bugs have been corrected.
2656 OpenAFS 1.5.63 (2009-09-11)
2660 * The restorevol command is now documented and installed as a user
2663 * The uss command now properly translates vldb entries to its expected
2664 format when handling them in all cases.
2666 * Documentation now refers to Kerberos instead of kaserver.
2668 All server platforms
2670 * bosserver now handles BosConfig.new when restarting, allowing
2671 configuration to be replaced at restart time rather than with bos
2672 delete and bos create. Documentation is updated to reflect this.
2674 * The demand attach fileservice not longer potentially hangs trying to
2675 terminate demand-salvages which have already exited.
2677 * The demand attach fileservice has been modified to avoid spurious
2678 'SYNC_putRes: write failed' warnings when some protocol messages
2679 cannot be acknowledged due to the sender terminating the connection.
2681 * In the event of failure to contact the vlserver or ptserver, the
2682 fileserver will not exit and trigger a forced salvage. It will
2683 continue to try in the background to contact the needed services.
2685 * The salvager can now repair certain cases of a damamged vnode index.
2687 * The accessDate metadata for a volume is now updated correctly.
2691 * CRITICAL: Some applications for example those based on Cygwin were
2692 unable to access data stored in the AFS name space. Explorer Shell
2693 also experienced inconsistent behavior. This is fixed.
2695 * CRITICAL: Multiple AFS pioctl requests issued nearly simultaneously
2696 by applications could result in pioctl responses being received by
2697 the wrong requester. This in turn could result in application
2698 crashes. symlink.exe, fs.exe, afslogon.dll, afscreds.exe, and the
2699 netidmgr afscred.dll plugin were all affected.
2701 * Some XP machines running 1.5.62 had trouble saving roaming profile
2702 data. This is fixed.
2704 * Integrated Logon (afslogon.dll) did not function with domain
2705 specific configurations.
2707 * Ensure that access denied and over quota errors experienced while
2708 storing data to the file server do not result in on-going retry
2711 All UNIX client platforms
2713 * Except on Solaris and AIX, the compiler may now be overriden at
2714 configure time by setting the CC environment variable.
2716 * afsd now properly deals with large cache partitions.
2720 * Build shared libafsauthent and libafsrpc.
2724 * Kernel module DKMS support now installs an unstripped module to
2725 allow debugging information to be collected.
2729 * Preferences pane properly updates token information.
2733 * klog will now properly handle passwords of 8 or fewer characters
2734 with an AFS string to key on hosts able to run 64 bit binaries.
2736 * A panic at AFS shutdown due to "NO PCB" on a udp_lock has been
2739 * The panic decoder script included in the source now properly handles
2740 32 and 64 bit panics.
2744 * Avoid defining AFS_KERBEROS_ENV globally as it creates a circular
2747 * Build shared libafsauthent and libafsrpc.
2751 * Build shared libafsauthent and libafsrpc.
2754 OpenAFS 1.5.62 (2009-08-28)
2758 * Numerous invisible changes to improve code maintainability,
2759 portability and enhanceability.
2763 * CRITICAL: Fixes two errors that can result in data loss when storing
2764 data to the file server.
2765 1. Failure to Store Portions of Unaligned Writes
2766 2. Failure to Store Data to File Servers Lacking Large File Support
2767 Read the announcement for more details:
2768 http://www.openafs.org/pipermail/openafs-announce/2009/000305.html
2770 * CRITICAL: The cache manager daemon thread could terminate when the
2771 machine enters suspend mode. This daemon thread performs the
2772 background check of down servers, offline volumes, callback
2775 * CRITICAL: Integrated Logon (afslogon.dll) was terminating
2776 unexpectedly. Error checking has been improved and NULL pointer
2777 dereferences after Lsa API calls fail have been eliminated.
2779 * For the first time, the OpenAFS SMB Server supports the DCE RPC
2780 services SRVSVC and WKSSVC. Browsing \\AFS with the Explorer Shell
2781 or NET VIEW will now be faster and provide additional functionality.
2782 No longer will cell names longer than 12 characters be truncated.
2784 * Improvements to DFS Referral request processing have been
2787 * Unnecessary DNS lookups of share names are avoided improving
2790 All UNIX client platforms
2792 * Non-Kerberos PAM modules work correctly again.
2796 * MacOS 10.6 (Snowleopard) is now supported, both 32 and 64 bit mode.
2798 * Updates to the AFSCommander preferences pane.
2800 * Installer now permits cell names with dashes.
2803 OpenAFS 1.5.61 (2009-08-06)
2807 * Correct another race condition in the Rx library that could result
2808 in an unexpected panic while freeing the Rx call iovq.
2810 * rx packet resend and data packets sent counts were incorrect.
2812 * fs setquota, fs setcachesize, vos setfields, and vos create now
2813 accept human readable orders of magnitude. (K, M, G)
2815 * fs listquota fixed to permit large quota sizes to be displayed.
2817 * Correct documentation of bosserver permissions requirements.
2819 * Modify vlserver to avoid potentially corrupting the database through
2822 * Generalized support for fast Rx timeout due to network
2825 All server platforms
2827 * Allow audit logs to be sent via sys5 IPC message queues instead of
2832 * If a file server becomes inaccessible while the cache manager has
2833 dirty buffers to write, the afsd_service buf_IncrSync thread can
2834 attempt to use 100% of the cpu.
2836 * Fix "fs newcell" which was broken in 1.5.60.
2838 * Do not attempt to synchronize dirty buffers if the associated volume
2839 is known to be unavailable.
2841 * Modify behavior of a Freelance mountpoint target that does not
2842 specify a cell. Instead of assuming the target volume is in the
2843 Freelance.Local cell, use the workstation "Cell" specified in the
2844 registry. A mountpoint target of "#root.cell." will now mean the
2845 root.cell volume in the workstation cell for the current session.
2846 If the workstation cell changes from "athena.mit.edu" to
2847 "andrew.cmu.edu", the referenced volume will also change without
2848 requiring that the mount point targets be altered.
2850 * Add cm_FindServerByUuid(). Re-implement RXAFS_InitCallBackState3()
2851 to permit the server Uuid to be used to lookup the server object and
2852 from that determine the cell. This permits callbacks that are
2853 received from alternate addresses to be processed with a known
2854 server object. Previously a request from an unknown server would
2855 clear all callbacks from all cells.
2857 * Fix a bug that prevented optimal performance when using a non-zero
2858 value for 'daemonCheckVolCBInterval'. As a reminder, when
2859 "daemonCheckVolCBInterval" is set to a non-zero value, all .readonly
2860 volume callbacks are automatically renewed 90 minutes before their
2863 * Fix automatic ranking of vldb servers whose values are obtained from
2864 the CellServDB file.
2866 * Add failover for RX CALL TIMEOUT errors when the volume is readonly
2867 or the call is to a vldb server.
2869 * Add registry based cell search functionality to NetIdMgr,
2870 afs_config.exe, and klog.exe.
2872 * afsconf_GetCellInfo() has been modified to perform gethostbyname()
2873 lookups on the host names in the CellServDB instead of using the
2874 specified IP addresses. This provides aklog, pts, vos, etc. the
2875 same CellServDB behavior that the Windows Cache Manager uses.
2877 * When updating the stat cache entry callback of a .readonly object
2878 from the volume group object, update the file server reference to
2879 ensure it matches the most update to date callback.
2881 * Add proper support for processing callbacks from multi-homed file
2882 servers. Instead of comparing servers by cm_server_t pointer,
2883 compare them by UUID when the UUID is known.
2885 * During a shutdown short circuit the offline volume check daemon
2888 * Return the error code of RXAFS_FetchData / RXAFS_StoreData in
2889 preference to an error code reported by rx_EndCall.
2891 * Add "PerFileAccessCheck" registry value to permit testing against
2892 experimental file servers that include per-file acl support. This
2893 value is intentionally undocumented. It is not to be used by
2894 production environment deployments.
2896 * Fix a bug introduced in 1.5.60 that prevents the afs netidmgr
2897 provider from obtaining tokens when referrals are in play.
2899 * Add "fs chown" and "fs chgrp" commands to permit the owner and group
2900 of objects stored in AFS to be set from Windows.
2902 * Avoid performing background daemon operations when the machine is
2903 going into suspend mode.
2905 * Perform offline volume checks in most recently used order.
2907 * Prevent crash when a data version for a cache object goes backwards.
2909 * Multi-thread safe library versions are now being generated and used.
2910 mtafsubik.lib, mtafsutil.lib, mtafsvldb.lib, mtafsvol.lib.
2912 * Microsoft SMB Redirector (mrxsmb.sys) support for
2913 ExtendedSessTimeout values are now available on XP through Windows
2914 7. Add functionality to autodetect if such support is present on
2915 the machine. If so, configure it if necessary and dynamically
2916 adjust the AFS Rx timeout values accordingly.
2918 All UNIX client platforms
2920 * Fix out-of-tree source builds.
2924 * GUI installer now asks for local cell information.
2926 * AFS Commander preferences pane is now installed by default.
2930 * Avoid kernel panics due to null pointer dereferences in the network
2931 interface poller kernel thread.
2934 OpenAFS 1.5.60 (2009-05-31)
2938 * Retry volserver transaction creation on failure.
2940 * Allow building HTML and PDF documentation from included XML copies
2941 of User Guide, Admin Guide and Quick Start Guide for Unix.
2943 * Documentation updates and additional documentation.
2945 * Add -encrypt support to pts client.
2947 * Convert MR-AFS fs commands to OSD commands.
2949 All server platforms
2951 * Updated background sync process in fileserver to avoid a race which
2952 could result in a volume being taken offline.
2956 * On April 9th Microsoft released a Hot Fix for Windows Server 2003
2957 SP2 that corrects a deadlock in the smb redirector and also adds new
2958 functionality that permits the AFS SMB server to be given a longer
2959 timeout than is normally the case. New functionality has been added
2960 to configure these additional LanmanWorkstation\Parameter values.
2961 (This functionality has been backported to XP SP3 and is scheduled
2962 to be released on June 5th.)
2964 * Fix RT#124787, a race condition between "fs flush <dir>", "fs
2965 flushvolume", or "fs flushall" and on-going directory operations
2966 that can result in afsd_service.exe crashing.
2968 * Release Notes, User and Administrator guides are now shipped as
2969 indexed Windows HtmlHelp Files. (.chm). Shortcuts are provided from
2972 * A method of specifying Client CellServDB information within the
2973 registry has been added that can be used to either override the
2974 CellServDB file or force the use of DNS lookups for a given cell.
2975 See the release notes for details.
2977 * The pioctl interface now properly handles drive letter substitution
2978 to UNC paths. (SUBST <d:> <\\afs\cell\path>)
2980 * The BackConnectionHostNames registry value configuration was broken
2981 when dynamic re-establishment of Netbios Name registrations was
2982 added. This release restores the functionality.
2984 * All hidden vos.exe commands are now revealed.
2986 * Attempts to store the same dirty file chunk from multiple threads
2989 * The IsPathInAfs test in Explorer Shell Extension and fs.exe now
2990 permits broken symlinks to be treated as being in AFS.
2992 * vos.exe commands that output 64-bit integer values once again do so.
2993 This was broken in 1.5.59.
2995 * Cygwin Import Libraries are provided in the SDK for all OpenAFS
2996 DLLs. This permits building cygwin applications against OpenAFS
2999 * NSIS installer does a much better job of cleaning up files left over
3000 from previous installs.
3002 * libafsconf.dll moved from Client\Program to Common directory as is
3003 is now used by all modules for CellServDB processing.
3005 All UNIX client platforms
3007 * Write back changes on last store for memcache to avoid discarding
3010 * Abstract disk cache support to allow for path, fh, inode based
3011 caches with no need for messy ifdef structures each time a new type
3016 * Support as a userland port.
3020 * Corrected structure definition for userspace cache manager to allow
3025 * Corrected client locking support.
3027 * Updated patch to stop deadlocking in the kernel during mmap.
3029 * Avoid oops when setting up groups for PAGs to match keyrings.
3031 * Use Linux fh-based cache in cases where possible by default.
3035 * Corrected structure definition for userspace cache manager to allow
3040 * Support for OpenBSD 4.5.
3044 * Corrected support for server-side vos split interface.
3047 OpenAFS 1.5.59 (2009-04-06)
3051 * Increased service priority class to "High" to match the priority of
3052 system components that are dependent upon the a timely response.
3054 * SMB error responses avoid returning errors that could confuse the
3055 Microsoft SMB redirector into disconnecting the connection to \\AFS.
3057 All UNIX client platforms (except MacOS X 10.4 and 10.5)
3059 * OpenAFS 1.5.59 contains fixes for the client issues addressed by the
3060 security advisories OPENAFS-SA-2009-001 and OPENAFS-SA-2009-002.
3064 * Support for prerelease Linux 2.6.30 kernels.
3067 OpenAFS 1.5.58 (2009-03-30)

3081 * Fix byte order issues with fileserver host hashing.
3083 * Fix buffer size issues with butc.
3085 * Fix several Ubik recovery issues.
3087 * Avoid leaking file references in the fileserver.
3089 * Fix a race in DAFS while closing vnodes, and another offlining
3092 * volserver interfaces for volume splitting client.
3096 * [RT 124293] A race condition exists which can result in a crash.
3098 * [RT 124276] If the vldb is out of sync with the contents of the file
3099 servers, afsd_service will retry too many times when a file server
3100 reports a volume as not being present. Now if the list reported by
3101 the vldb is the same as the previously seen list, then the retry is
3104 * [RT 124276] Read-only volume failover was broken in 1.5.53 whenever
3105 accessing a volume results in VNOVOL or VMOVED.
3107 * [RT 124276] Prior to 1.3.70 the volume server reference list was not
3108 reference counted and would be prematurely freed while in use. When
3109 reference counting was added in 1.3.70 a bug was introduced that
3110 could result in service reference list corruption.
3112 * Add Windows Application Event Log warning messages for "Client SMB
3113 MPX value too large" and "Client SMB Buffer Size too small".
3115 * Renaming of files across directory boundaries would result in an
3116 invalid handle error when attempting to access the files after the
3119 * Fix the handling of Tran2 Set Path Info RPCs. Do not fail when a
3120 smb file descriptor cannot be found. The whole point of using a
3121 Path Info function is because an smb file descriptor wasn't
3124 * More edge cases in which dynamic addition of Freelance root.afs
3125 entries would get the wrong FID or where the root.afs directory
3126 would not be refreshed.
3128 * Buffer overflow could occur if the workstation cell name was longer
3129 than 64 characters. Crashes could occur in afscreds.exe,
3130 afslogon.dll, and afsd_service.exe.
3132 * VNOSERVICE and VOFFLINE errors were leaking and were exposed to the
3135 * Log file server uuid values as part of the cm_server object when
3136 available. Dump the cm_server object list in response to "fs
3139 * Optimize the performance of resetting access control lists when
3140 tokens are set or removed.
3142 * Remove symlink recursion tests and increase max symlink count to 64
3145 * Windows specific Rx performance improvements.
3147 * Support for Network Identity Manager 2.0
3149 All UNIX client platforms
3151 * Avoid issues with freeing resources at shutdown.

3198 * Volumes are properly marked in use on creation and subsequently on
3199 examination with vos.
3203 * Undo the "UAC manifest fix" applied to afs_config.exe.
3205 * Ensure that Freelance allocation of vnodes follow the AFS convention
3206 of odd vnodes are directories and everything else is an even vnode.
3208 * Add Freelance logic to mount point and symlink evaluation functions.
3210 * Enhance smb_ParseASCIIBlock() so that it can handle all of the
3211 STRING formats defined by the CIFS Technical Report 1.0.
3213 * Validate the output of smb_ParseASCIIBlock() in all callers. Return
3214 CM_ERROR_BADSMB if the STRING field cannot be parsed.
3215 CM_ERROR_BADSMB will cause the contents of the packet to be logged.
3217 * If multiple SMB Raw Write operations were taking place at the same
3218 time, there could be data corruption because unique event objects
3219 were not generated for each Netbios receive operation.
3221 All UNIX client platforms
3223 * Userspace AFS library can now deal with large files when supported
3226 * Numerous updates to disconnected AFS support, including changes to
3227 allow reconnection to work in more circumstances.

3260 * Additional rx debugging support is available as a conditional
3263 * A race condition in Rx leading to a panic has been corrected.
3265 * Rx idle time tracking has been corrected.
3267 * ubik clone server support has been corrected.
3269 All server platforms
3271 * Salvager no longer leaves cores in vice partitions.
3273 * The vol-dump tool now supports dumps larger than 2gb where possible.
3275 * Operations on multiple files now report all FIDs in the audit log.
3277 * butc XBSA support now works correctly on amd64.
3281 * The NetIDMgr AFS Provider automated configuration logic was broken
3282 by the introduction of Kerberos referrals. If the realm of the
3283 identity cannot be determined, the workstation cell is now assumed
3284 to belong to the newly created identity.
3286 * Avoid a reference count under flow during rename operations.
3288 * Avoid a crash caused by treating an arbitrary length directory
3289 search mask as an 8.3 mask.
3291 * Prevent rename operations if a case insensitive match for the target
3292 name already exists and does not refer to the object being renamed.
3294 * Increase the maximum number of background daemons to 64.
3296 * Fix the UAC manifest applied to afs_config.exe
3298 All UNIX client platforms
3300 * Updates to disconnected AFS support.

3382 * Updates for new Tivoli X/Open API finding.
3384 * A double-free is corrected in Rx.
3386 All server platforms
3388 * Ubik cleans up file descriptor cache correctly when doing recovery.
3390 * Enhanced vldb error checker included.
3394 * Prevent a crash that could occur when multiple file / directory
3395 change notifications are processed simultaneously.
3399 * AFS claims more free space so Finder will attempt file copies.
3403 * Avoid spurious ENOENT when calling gwtcwd() on a volume root.
3405 * Avoid spurious ENOTDIR during fakestat.
3408 OpenAFS 1.5.53 (2008-09-26)
3412 * rx avoids many packet leaks.
3414 * rx jumbogram disabling now works (and is the default).
3416 All server platforms
3418 * Demand Attach fileserver tries to avoid issues tracking offline
3423 * Many potential deadlock conditions due to out of order lock
3424 acquisitions have been corrected.
3426 * A race condition resulting in an undercount on the cm_scache_t
3427 reference counts has been corrected.
3429 * An empty string when sent as an ioctl path is now properly
3430 interpreted as meaning the current directory. This affects "fs
3431 lsm", "symlink list", etc.
3433 * Fix smb string parsing differences where the smb protocol
3434 documentation does not match the actual Windows implementation.
3436 * Random access denied errors fixed.
3438 * A file server lock synchronization issue was corrected in SMB
3439 NTCreateX and NTTranCreate operations. This bug prevented properly
3440 operation when loading roaming profiles.
3442 * Fix a heap overwrite error during server probe operations if a new
3443 server is added while a probe operation is in progress.
3445 * Fix an LSA memory leak that was the result of an LSA error.
3447 * Do not leak cm_cell_t objects if the VLDB server lookup fails.
3449 * Only initialize rx mutex/lock objects once.
3451 * Do not nul terminate the AFS volume name when reported to Windows.
3453 * Improve VNOVOL error handling. Prevent updated vl information from
3454 being destroyed immediately after it was acquired. This bug
3455 prevented proper fail over when volumes are moved or removed from a
3458 * Remove volume id from the server volume list in response to VMOVED
3461 * "fs flushXXX" commands now destroy locally built B+ directory trees.
3463 * Prevent mixture of locally modified directory pages and file server
3466 * Fail over to alternate vl servers if a ubik error is returned.
3468 All UNIX client platforms
3470 * Disconnected AFS now supports read-write mode.
3472 * volserver now builds correctly.
3476 * AIX 6 is now supported.
3480 * FreeBSD 7 is now supported.

3486 * 2.6.x kmod compilation now uses kernel compile options always.
3488 * Support through 2.6.27.
3492 * Show more space free so Finder doesn't get confused.
3496 * Default to namei rather than inode.
3499 OpenAFS 1.5.52 (2008-08-18)
3503 * Initialize volume updateDate at volume creation.
3505 * Avoid potential corruption of directories during salvage.
3507 * Check for out of memory condition during allocation of additional Rx

3530 readonly volume or one that is marked with the readonly DOS
3533 * Fix a heap corruption error when reading the CellServDB file
3536 * Add the "RxUdpBufSize" registry value. The new default is 256KB.
3538 * Do not include trailing NULs in the directory search output.
3541 * Pre-allocate 64 Rx Packet buffers per thread in order to improve
3544 * For debugging: add smb lock requests and stat cache lock allocations
3545 to the output from "fs memdump".
3549 * Workaround broken sigwait() to allow fileserver to shut down
3550 correctly pre NetBSD 5.0.
3554 * Default to namei fileserver; Allow inode fileserver at configure
3559 * Try harder to avoid kernel panics for malformed requests.
3562 OpenAFS 1.5.51 (2008-07-29)
3566 * salvager tries harder to arrange for clients to get VBUSY while
3567 salvaging single volumes.
3569 * salvager avoids certain corruption when salvaging directories.
3571 * Rx connection clones disabled.
3575 * The 32-bit EXE 1.5.50 installer failed to properly install the C
3576 Runtime library. When used as an upgrade OpenAFS would continue to
3577 work but when used as a new installation, OpenAFS binaries would
3580 * Fixes the "fs" and "symlink" commands to properly parse Unicode path
3581 prefixes during the pioctl remote procedure call. This bug would
3582 result in file not found errors for files and directories that
3583 clearly exist. (Bug introduced in 1.5.50)
3585 * Large File support is disabled. (Bug introduced in 1.5.50)
3587 * Removes the possibility of a deadlock during volume location update
3588 operation if all of the reported file servers are unreachable at the
3591 * Ensures that reference counts are properly incremented/decremented
3592 on Rx connection objects used for volume location RPCs.
3594 * Over Quota errors during cm_FSync() calls would lead to an infinite
3595 loop as the error was never propagated to the caller.
3597 All UNIX client platforms
3599 * Bugfixes to disconnected AFS support in the cache manager.
3602 OpenAFS 1.5.50 (2008-07-16)
3606 * volserver puts recloned volumes back online before returning the
3607 volume to the fileserver, avoiding spurious VNOVOL errors.
3609 * Updated TSM X/Open API support available.
3611 * Demand Attach fileserver will not crash due to accesses during
3614 * Substantial documentation updates.
3616 * Demand Attach fileserver state tracking and analyzer tool
3619 * UAFS userspace cachemanager updates.
3621 * Corrected support for anti-meltdown protection in the client.
3625 * UNICODE Character Set Support.
3627 * Pioctl interfaces to the cache manager have been refactored to
3628 provide layering between the SMB specific code and the general
3629 purpose ioctl operation.
3631 * Garbage collect dead SMB virtual circuits as soon as they are no
3632 longer being referenced. This avoids problems with outstanding
3633 locks not being dropped when the virtual circuit becomes invalid.
3635 * Remove the IBM Administration Reference documentation and replace it
3636 with the OpenAFS Command Reference Manual.
3638 * Avoid calling rx_SetDeadTime and rx_SetHardDeadTime functions each
3639 time a connection is about to be used. Do not hold a lock on the rx
3640 connection object while it is being selected. This avoids a race
3641 between threads attempting to set the timeout values and removes a
3642 bottleneck that was hampering performance.
3644 * Ensure that the smb directory attribute is set for all directory
3647 * Replace the VC Runtime EXE installer with the MSI installer in the
3648 NSIS installer scripts.
3652 * Support for updates to OpenSolaris.
3656 * Correct dentry revalidation for cross-directory renames.
3658 * Updated rpm packaging materials for 1.5 release series and 2.4
3661 * Corrected syscall table probing.
3663 * NFS translator updates for current kernels.
3666 OpenAFS 1.5.39 (2008-06-24)
3670 * Updates for Demand Attach fileserver.
3674 * Fix two memory leaks.
3676 * Fix one missing lock.
3678 * Handle access denied errors when writing dirty buffers.
3680 * Fix two errors that would cause the *experimental* AFS Servers
3684 OpenAFS 1.5.38 (2008-05-24)
3688 * Add read-only disconnected support.
3691 OpenAFS 1.5.37 (2008-05-21)
3695 * Includes a number of optimizations for testing.
3698 OpenAFS 1.5.36 (2008-05-09)
3702 * Rx optimizations now attempt to deal with high latency WANs.
3704 * Client will not wait infinitely for a server which is not providing
3705 data. Additional servers will be polled without marking the server
3706 which is not providing data down.
3708 * vos move will not erroneously unlock locked vldb entries on failure.
3710 All server platforms
3712 * Fileserver avoids a potential infinite loop when a client
3713 relinquishes an address.
3715 * Fileserver large setting now configures more threads.
3717 * Fileserver properly registers uuids of new clients.
3719 * Ubik servers do not improperly hide updates from clients.
3721 * Fileservers reserve enough file descriptors such that each thread
3722 can cache one to avoid spurious errors.
3726 * Fix a cm_buf_t reference count leak when attempts to write dirty
3727 buffers to the file server from within cm_IncrSyncer() fail.
3729 * Prevent udebug from crashing.
3731 * Another VNOVNODE issue fixed. When writing a dirty buffer to the
3732 file server, if VNOVNODE is received, mark all buffers as invalid
3733 without further attempts to contact the file server.
3736 =======> Changes back to 1.3 have not yet been incorporated here <=======
3741 * -nosettime is now the default for afsd. Use "-settime" to get the
3744 * OpenBSD is now supported.
3746 * Mountpoint directory information is now only faked for cross-cell
3747 mountpoints when using the -fakestat flag (e.g. for the directories
3748 under /afs, but not for most other volumes mounted inside the cell).
3749 The -fakestat-all switch can be used to fake information for all
3752 * When fakestat is enabled on MacOSX, the Finder can be used to browse
3753 a fully-populated /afs directory. However, this precludes reliable
3754 use of entire volumes as MacOS bundles (i.e. containing a Contents
3755 directory in the root of the volume).
3757 * Mountpoint directory information can be faked by the cache manager,
3758 making operations such as stat'ing all cells under /afs much faster.
3759 This is enabled by passing -fakestat to afsd, but might not be stable
3765 * The kaserver now defaults to not allowing interrealm authentication,
3766 due to security vulnerabilities in the krb4 protocol. The new
3767 "-crossrealm" flag to the kaserver is provided to reenable interrealm
3768 authentication if desired.
3770 * RedHat Linux 9.0 is now supported.
3772 * Solaris 9 12/02 is now supported. Solaris 7 and 8 x86 should now
3775 * On Linux machines using 2.2 series kernels, 2.2.19 or higher is now
3778 * An OpenAFS 1.2.9 afsd will not work with kernel modules built from
3779 an earlier OpenAFS release. In general, using a mismatched afsd and
3780 kernel modules set is unsupported; it is not recommended that you use
3781 such a configuration on a regular basis.
3786 * Mountpoint directory information is now only faked for cross-cell
3787 mountpoits when using the -fakestat flag (e.g. for the directories
3788 under /afs, but not for most other volumes mounted inside the cell).
3789 The -fakestat-all switch can be used to fake information for all
3792 * HPUX 11.0 is now supported.
3794 * It is now possible for AFS to use Kerberos 5 directly, via rxkad 2b.
3795 See the OpenAFS 1.2.8 Release Notes for more information on using this
3798 * An NFS translator kernel module is now included and compiled by
3799 default for Solaris only.
3804 * MacOS X 10.2 is now supported. FreeBSD 4.3 and later support is
3805 included in this release, but is still under active development and
3806 should only be used by those doing active development on the OpenAFS
3809 * When fakestat is enabled on MacOSX, the Finder can be used to browse a
3810 fully-populated /afs directory. However, this precludes reliable use
3811 of entire volumes as MacOS bundles (i.e. containing a Contents
3812 directory in the root of the volume).
3814 * The fileserver will now use Rx pings to determine if clients are
3815 reachable prior to allocating resources to them, to prevent asymmetric
3816 clients from consuming all fileserver resources.
3821 * Mountpoint directory information can be faked by the cache manager,
3822 making operations such as stat'ing all cells under /afs much faster.
3823 This is enabled by passing -fakestat to afsd.
3825 * Solaris 9 FCS and Solaris 7 and 8 x86 are now supported.
3830 * A remote denial of service attack in the AIX and IRIX clients has been
3831 fixed. Users of those platforms are strongly encouraged to upgrade.
3833 * Fixed race conditions in fileserver that could result in crash.
3838 * Server logfiles now more consistant about format in which hosts are
3841 * vfsck on Solaris will now allow force runs (using -y flag) even if old
3847 * Cell aliases for dynroot can be specified in the CellAlias file in
3848 /usr/vice/etc or /usr/local/etc/openafs, in format "realname alias",
3849 one per line. They can also be managed at runtime with "fs newalias"
3850 and "fs listaliases".
3855 * Solaris 9 and Linux PA-RISC are now supported.
3857 * fileserver will not erroneously delay legitimate errors for 3 seconds
3858 after 10 errors are returned (e.g. stat() on a directory you can't
3861 * Rx MTU calculation now works for Irix, Solaris and Linux
3863 * If afsd is started with the -dynroot flag, /afs will be locally
3864 generated from the CellServDB. AFSDB cells will be mounted
3865 automatically upon access.
3867 * The namei fileserver allows vice "partitions" to be directories
3868 instead of partitions and will attach and display accordingly.
3869 Creating the file "AlwaysAttach" in the /vicepX directory is used as
3870 the trigger to attach it.
3872 * TSM support for butc no longer requires editing a Makefile, simply
3873 specify the --enable-tivoli-tsm configure option.
3875 * Linux builds no longer require source changes every time the kernel
3876 inode structure changes; the OpenAFS sources will now configure itself
3877 to the actual inode structure as defined in the kernel sources.
3882 * vfsck on Digital UNIX and Solaris will now refuse to fsck mounted
3888 * AFS now supports --prefix and the other directory options of
3889 configure. By default AFS builds assuming it will be installed in
3890 /usr/local. In order to get traditional AFS directory paths (/usr/afs
3891 and /usr/vice/etc) use the --enable-transarc-paths option to
3892 configure. More details on the new directory layout are found in
3898 * Windows 95/98/ME/NT/2000 - Consistent versioning: Installation, AFS
3899 Control Center, Client dialog boxes and properties pages for
3900 executables display a consistent OpenAFS version number. Installation
3901 detects previous installation and prompts the user for upgrade
3904 * Windows 95/98/ME/NT/2000 - Installation features: During installation
3905 the user can select the source of the CellservDB file, AFS home cell,
3906 and drive mappings. During installation a drive path mapping can
3907 include a variable that will be substituted with the current UserName
3910 * Windows 2000/NT - Integrated logon: The Integrated Logon feature
3913 * Windows 95/98/ME - Logon script features: The Windows 95/98/ME client
3914 now offers a command-line option for starting up the AFS client
3915 without authenication. It is now possilbe to start the AFS client
3916 first and obtain tokens, and map drives all through Windows scripts.
3917 This helps using Windows 95/98/ME client in Kerberos 5 environment.
3919 * Windows 2000/NT - LANA numbers: AFS client now scans the LANA numbers
3920 to establish the correct NETBIOS connection. NetBEUI is no longer
3921 needed. The user no longer needs to find the correct LANA number.
3923 * Windows 2000/NT - OpenAFS naming consistancy: Further progress has
3924 been made to remove references to "Transarc AFS" and replace with
3930 * AFS now builds with configure. The README for building has been
3931 updated and includes full details.
3933 * A client system can now have multiple sysname values for @sys. They
3934 will be searched in order when looking up files in AFS. The
3935 -newsysname argument to fs sysname can be repeated to set multiple
3938 * A new system group is created for new cells (system:ptsviewers with id
3939 -203). If this group exists, members of this group can examine and
3940 read the entire protection database. They can examine all users and
3941 groups and can get the membership of any group.
3943 * A new program, pt_util has been added to the distribution. This
3944 program allows users to print the contents of the protection database
3945 or to edit the protection database without running a ptserver. It can
3946 be used to set up a new cell without ever running in noauth mode. Run
3947 pt_util -h for help.
3949 * The fs setcrypt and fs getcrypt commands have been added. These
3950 commands allow the system administrator to require that the client
3951 encrypt all authenticated traffic between the client workstation and
3952 AFS. The encryption used is weak, but is likely better than sending
3953 unencrypted traffic in most environments. Some functions, such as
3954 looking for a volume may not be encrypted, but data transfer certainly
3955 is. By default data is not encrypted. At this time no significant
3956 experimentation with server performance has been conducted.
3958 * By default AFS is compiled with AFS_AFSDB_ENV, enabling the -afsdb
3959 option to be given to afsd on startup. If this option is used, then
3960 new cells will be looked up using AFSDB records stored in DNS if they
3961 are not found in CellServDB. This means that users can create
3962 cross-cell mountpoints in directories they control to access cells not
3963 in root.afs, and that cells in root.afs need not be in the client's
3966 * AFS database servers can be marked as read-only clones. Surround the
3967 hostname in square brackets on the bos addhost command and the
3968 database server will never be elected sync site. This is useful for
3969 cells distributed over a wide region.
3971 * The AFS servers now support the -syslog flag. This flag causes them
3972 to log to syslog rather than to files. This flag is not supported on
3973 NT. For all servers besides the salvager, the flag can also be
3974 specified as -syslog=facility, where facility is an integer facility
3975 code from syslog.h. A -syslogfacility option is provided for the
3976 salvager to accomplish the same goal.
3978 * If the --enable-fast-restart flag is given when configuring AFS, then
3979 the salvager supports the -dontsalvage flag which causes it to exit
3980 without salvaging any volumes. If this is configured into the third
3981 command of a fs process, then the fileserver will start without
3982 salvaging. It will fail to attach volumes that need salvaging and
3983 they can be salvaged manually. This provides significantly better
3984 server startup performance at the cost of administrative complexity.
3986 * If the --enable-bitmap-later flag is given when configuring AFS, then
3987 the fileserver creates bitmaps for free vnodes on demand, allowing
3990 * If bosserver finds a BosConfig.new file at startup, it reads this file
3991 and renames it to BosConfig. This allows bosserver to be reconfigured
3994 * The bosserver can be placed in a restricted mode in which AFS
3995 superusers are only granted limited access to the server host. The
3996 following functionality is disabled when restricted mode is in use:
3999 bos getlog (except for files with no '/'s in their name)*
4005 specific exceptions are made for functionality that "bos salvage"
4008 A cron bnode who's name is "salvage-tmp", time is now, and command
4009 begins with "/usr/afs/bin/salvager" may be created. This bnode deletes
4010 itself when complete, so no special "delete" support is needed. This
4011 functionality may be removed in the future if a "Salvage" RPC is
4014 The file with the exact path /usr/afs/logs/SalvageLog may be fetched,
4015 since that is how bos salvage [...] -showlog is implimented.
4017 Restricted mode is enabled using a new bos command (bos setrestricted)
4018 or bossever command line switch (bosserver -restricted). Restricted
4019 mode can be disabled by a) sending the bosserver process a SIGFPE
4020 (which will then allow restricted operations until the next restart or
4021 setrestricted command) or b) editing /usr/afs/local/BosConfig (or
4022 BosConfig.new), and restarting the bosserver.
4024 * The bos UserList of trusted administrators can now contain cross-realm
4025 Kerberos principals.
4027 * udebug now takes --server not --servers.
4029 * Several error messages have been improved to include volume numbers.
4031 * Several new ports have been included for UNIX platforms: Darwin
4032 (ppc_darwin_12 and ppc_darwin_13), Linux 2.4 (i386_linux24), Linux on
4033 the Powerpc (ppc_linux22 and ppc_linux24), Linux on the Sparc
4034 (sparc_linux22, sparc64_linux22 and sparc64_linux24).
4036 * Incomplete FreeBSD and Alpha Linux ports are included. The FreeBSD
4037 port has a working server and the Alpha Linux port has a partially
4040 * A native client for Windows 95/98/ME has been added to the
4041 distribution. With this program, a gateway machine is no longer
4042 required for Windows 9x to access AFS files. One drive letter will be
4043 created on your machine by default - Z:. The Z: drive will be the
4044 root of the AFS tree, allowing you to browse all sites that have AFS
4045 servers available. Additional drive letters can be defined for other
4046 AFS directories. A Windows Explorer shell extension is included that
4047 allows you to right click on items within an AFS tree to bring up an
4048 "AFS" menu item and perform various operations on a file or directory.
4049 The most useful item is "Access Control Lists", which allows you to
4050 view and edit the permissions of a particular directory. Command line
4051 tools are also available in the install directory. These commands
4052 include klog, unlog, tokens, kpasswd, symlink, fs and pts. The
4053 installable includes a readme file that contains more information on
4054 how to use the client program and known issues.
4056 * Support for large caches in afsd. Cachefiles are stored in
4057 subdirectories. The default is 2048 files per subdirectory, which
4058 should work fine in most situations. You can use the new afsd option
4059 -files_per_subdir to change this number. Note that the first time you
4060 run afsd with this patch, your cachefiles will get moved into
4061 subdirectories. If you subsequently run an older version of afsd, you
4062 will lose all your cached files.
