14 * Avoid some potential performance losses in the wire protocol (14503
17 * Avoid client connections hanging forever when the server is

22 * Avoid Rx calls getting stuck on the incoming call queue for busy
25 * Avoid a possible salvageserver deadlock (14283)
27 * Fixed salvageserver's parsing of the "-parallel all<number>" argument
30 * Avoid potential salvager crashes (14515 14614)

33 'fs' bnode in addition to the 'dafs' bnode (14665)
35 * Avoid erratic vlserver behaviour due to overflowing the maximum
36 VLDB size of 2 GB. Log a message and return an error instead (14288)
38 * Fixed a ptserver issue where 'pts mem -expandgroups' failed when
39 supergroups were enabled (14345) (RT #135147)
41 * Take read-only volumes offline while being converted to read-write
42 ones with "vos convertROtoRW", preventing them from ending up in an
43 inconsistent state when accessed during the conversion (14433)
45 * Avoid inconsistent volume states due to interrupted rename operations
46 and other potential issues (14449 14450)
48 * Add new variants to asetkey's "delete" command to allow deleting
51 * Improved ubik performance and robustness (14141 14142 14365)
53 * Fixed building the vol-bless utility, which is now also built by
54 default but still not installed and distributed (14601)
56 * Fixed parsing of "-cores none" when bosserver is started this way
61 * Avoid crashes or panics when potentially recoverable errors
62 during cache I/O are encountered (14286)
64 * Avoid flooding servers with NAT pings, which could happen under
65 certain circumstances (14364)
67 * Avoid possible panics during client startup or shutdown (14393 14441)
69 * Avoid potential buffer overflows by one character in the "bos" client
70 program and in libadmin client programs (14664 14666 14698)
72 * Fixed a slow kernel memory leak triggered by retrieving tokens for
73 userspace commands as an authenticated user (14667 14663) (RT #135238)
75 * Fixed several potential problems in "aklog -keytab" (14478 14479
78 * Performance improvements (14391)
80 * Avoid unexpected "cold" shutdowns upon umount /afs on platforms

85 * Fixed building the afscp utility, which is still not built by default
90 * Support mainline kernels up to and including 5.13 (14267 14268 14269
91 14315 14563 14564 14565) (RT #135242)
93 Note that as of mainline kernel 5.13, OpenAFS currently won't build
94 on PowerPC due to a new ABI restriction.
96 * Avoid failures of cache I/O operations in the context of tasks
97 restricted by security mechanisms like AppArmor (14082 14099)
99 * Avoid a crash while loading the kernel module when reading from
100 /proc/fs/openafs/CellServDB before afsd has started (14284)

104 * Restore the -setpag functionality in some older utilities like klog
109 * Added support for release 11.0 "Big Sur" (14597 14598 14605 14600)
113 * Support releases 11.2, 12.1, 12.2 (14520 14537 14590)
115 * Add a wide range of FBSD specific fixes and improvements (14521..36)
121 * Fix initial Rx Connection ID (CID) generation.
122 Remove stale initialization and overflow detection logic that resulted
123 in connection failures due to all CIDs being set to 0x80000002.
124 (14493, 14494, 14497)
130 * Address warnings and errors encountered when building OpenAFS with
131 modern compilers like gcc9 or recent clang (13727..45 13749..50 13756
134 * Avoid some rare cases of Rx calls getting stuck in the incoming queue
137 * Display the usage of simple commands (commands without subcommands) when
138 run only with the -help option (13894)
140 * Fix a memory leak in the cache manager and the fileserver while
141 processing "fs uuid" or "fs setcbaddr" (13899)
143 * Fix a memory leak when reopening krb local realms configuration (13900)
145 * Avoid possible crashes when freeing kerberos contexts (13902)
149 * Do not leave empty directories behind in the file server vice partition
150 when running the "vos zap -force" command (13897)
152 * Fix "vos zap -force" failures when the volume being zapped does not have
153 an entry in the fileserver's volume group cache (e.g., during fileserver
156 * Relax the length limits on some membership lists used in ptserver RPCs,
157 introduced in release 1.8.0 to prevent denial of service attacks, to
158 accommodate use cases of some larger existing sites (13844)
160 * Improved diagnostics and error messages (13898 13906..8 13938)
162 * Ensure that fileservers running in readonly mode actually reject all
163 write requests, but introduce a -admin-write switch allowing writes
164 by members of the system:administrators group (14018 14019)
168 * Require the -insecure_des switch to be passed to aklog and klog.krb5
169 to make them work with single-DES encryption types (13791)
171 * Avoid a panic due to a retryable error - retry in a background request
174 * Avoid blocking other functions on the completion of some potentially
175 long-running RPCs issued by the server (13893)
177 * Fix a potential memory leak in "fs getserverprefs" when the pioctl fails
180 * Avoid the local cache incorrectly reflecting the state of a file on the
181 fileserver after flushing large chunks of data to the server. This
182 issue was present on FreeBSD clients, but probably not Linux/Solaris
183 ones (13951) (RT #135041)
185 * After a VLDB lookup of a read-write volume already failed, don't bother
186 looking up corresponding read-only or backup volumes since those lookups
187 are bound to fail, in order to make the client more responsive and
188 avoid unnecessary load on the vlserver (13968)
190 * Allow a "vos rename" to succeed if the new volume name is the same as
191 that in the current VLDB, to make it possible to complete a previously
192 interrupted volume rename (14055)
194 * Allow processes which are sleeping due to PAG throttling to be killable
197 * Fix set PAG failures due to signals (13975).
201 * Support mainline kernels up to and including 5.7 (14069 14094 14095
204 * Make builds succeed with --enable-checking for mainline kernels
205 5.3-rc2 and later (13910)
207 * Avoid possible deadlocks (13748 13765)
209 * Fix build of libuafs on ppc64le (14104)
211 * Fix build on certain recent 32-bit distributions (14234) (RT #135084)
215 * Support building, packaging and notarization on macOS 10.15 "Catalina"
220 * Build fixes (13848..52)
227 * Fix OPENAFS-SA-2019-001: information leakage in failed RPC output
228 Generated RPC handler routines ran output variables through XDR encoding
229 even when the call had failed and would shortly be aborted (and for
230 which uninitialized output variables is common); any complete packets
231 assembled in the process would be sent to the peer, leaking the contents
232 of the uninitialized memory in question.
234 * Fix OPENAFS-SA-2019-002: information leakage from uninitialized scalars
235 Generated RPC handler routines did not initialize output variables of
236 scalar (fixed-length) type, since they did not require dedicated logic to
237 free. Such variables allocated on the stack could remain uninitialized
238 in some cases (including those affected by OPENAFS-SA-2019-001), and the
239 contents of uninitialized memory would be returned to the peer.
243 * Fix OPENAFS-SA-2019-003: fix crash in database servers
244 The ubik debugging RPCs prioritize being fast and non-disruptive to
245 database operations over strict correctness, and do not adhere to the
246 usual locking protocol for data access. A data race could cause a NULL
247 dereference if the second memory load was not optimized out by the
254 Build system updates to remove obsolete autoconf macros and remove missing
255 script warning during builds (13480, 13481, 13482, 13483, 13484, 13486,
258 Build system update to fix a conditional check in the pthread.m4 autoconf
261 Build system update to create the man3 subdirectory, fixing a
262 reported build failure (13535).
264 Remove the last reference to src/mcas in the documentation (13558).
268 Fix fileserver's parsing of the options -vlruthresh, -vlruinterval,
269 -vlrumax and -novbc (13680).
271 Fixes to make ptserver's behaviour when run in restricted mode consistent
272 with the documentation: Non-members of the system:administrators group
273 are no longer allowed to issue the adduser, setfields and delete pts
274 commands, and all members of system:administrators are now allowed to
275 issue pts commands in this mode, not just the admin principal (13686..88).
279 Fix missing Rx call clean-up after failing to read dcaches from a file
282 Fix an Rx call leak for calls aborted by a connection abort after the call
283 was initialized but before use (13517).
285 Remove the obsolete afs_xosi lock to remove unnecessary serialization of
286 VOP_GETATTR calls. This can lead to improved performance under heavy
289 Increase the size of the Directory Name Lookup Cache (DNLC) to improve
290 cache performance (13559).
292 Fix getting tokens for cells with a three character name (13679).
294 Avoid a misleading message about the cell being used when aklog is run
295 with the -cell parameter but the AFSCELL environment variable is set to
296 a different cell (13676).
298 Build system update to honor the CFLAGS environment variable when building
303 Support for mainline kernels up to 5.3 (13787, 13789).
305 More fixes for improper use of ENOENT fixes to avoid incorrect use of linux
306 negative dentry cache, which can lead to false ENOENT errors (13542, 13543,
307 13590, 13692) (RT #134904).
309 Return errors instead of returning incomplete directory listings when the
310 directory objects are incomplete in the cache (13591).
312 Add ppc64le_linux26 sysname for the ppc64le architecture (13636, 13637,
315 Fix configure check for a kernel time function in order to build on
318 RPM packaging update for RHEL8 adding a build requirement to ensure the
319 kernel module can be built from the SRPM (13563) (RT #134900).
321 On systemd based RHEL/Fedora systems, start the client after dkms startup
322 is finished if the latter is installed and enabled, to avoid attempting
323 starts without the kernel module being available yet (13674) (RT #134974).
327 Build system updates for MacOS (13584).
331 Add CTF debugging records to userspace objects to improve debugging
334 Convert the cache manager vnodes to be non-embebbed on Solaris 11 in order
335 to make the cache manager more resilient across Solaris 11 changes (13524,
336 13525, 13526, 13527, 13528).
343 * Improved diagnostics and error messages (13186 13411 13417)
345 * Avoid sending RX packets with random garbage in the userStatus field
348 * Fixed detection of the RX initialization status (13416)
350 * Assorted fixes to avoid segmentation faults and other potential problems
351 by detecting internal errors rather than letting them go unnoticed
356 * Fixed a build problem accidentally introduced in release 1.8.2 (13328)
358 * Assorted efficiency improvements in the ubik implementation (13153 13218
361 * Fixed locking around transaction list processing in volserver to avoid
362 segmentation faults and other potential problems (13336 13337)
364 * When the volserver attempts to remove a temporary volume after a
365 transaction, but the volume was already removed, e.g., by the salvager,
366 this is no longer treated as an error (13235)
370 * Update the CellServDB to the latest version from grand.central.org from
371 May 14th 2018 (13409)
373 * Avoid a panic during cache initialization when allocating the required
376 * Add back the packet counters and timestamps to "vos status" output
377 which had been missing since release 1.8.0 (13421)
379 * Correctly handle errors encountered while reading data from the server
380 and writing it to the cache, e.g., due to a full cache partition (13443)
382 * Avoid a panic due to a recoverable error while flushing cache items
387 * Support mainline kernels 4.20 and 5.0 and distribution kernels with
388 backports from those (13405 13406 13440 13441 13442)
390 * DKMS-related fixes in Red Hat packaging (13438 13479)
394 * Support building and packaging on macOS 10.14 "Mojave" (13412 13413)
401 * Fix OPENAFS-SA-2018-002: information leakage in RPC output variables
402 Various RPC routines did not always initialize all output fields,
403 exposing memory contents to network attackers. The relevant RPCs include
404 an AFSCB_ RPC, so cache managers are affected as well as servers.
408 * Fix OPENAFS-SA-2018-003: denial of service due to excess resource consumption
409 Various RPCs were defined as allowing unbounded arrays as input, allowing
410 an unauthenticated attacker to cause excess memory allocation and tie up
411 network bandwidth by sending (or claiming to send) large input arrays.
413 * Fix OPENAFS-SA-2018-001: unauthenticated volume operations via butc
414 On systems using the in-tree backup system, the butc process was running
415 with administrative credentials, but accepted incoming RPCs over
416 unauthenticated connections; these incoming RPCs in turn triggered
417 outgoing RPCs using the administrative credentials. Unauthenticated
418 attackers could construct volue dumps containing arbitrary contents
419 and cause these dumps to be restored and overwrite arbitrary volume
420 contents; afterward, the backup database could be restored to its
421 initial state, hiding evidence of the unauthorized changes.
423 Running butc with -localauth now requires authenticated incoming
424 connections, and the backup utility makes authenticated connections to
425 the butc. Audit capabilities have been added to the butc RPC handlers.
426 Command-line arguments are provided to retain the (insecure) historical
427 behavior until all systems have been upgraded.
433 * Support for mainline kernel 4.18 and distribution kernels with backports
440 * Improve the usability and consistency of the public API: install missing
441 headers, and add additional symbols to the export list for shared libraries.
443 * Improved Rx abort generation: use the proper serial number for an existing
444 connection if possible, and 0 otherwise (to improve debugging).
446 * Assorted minor fixes in response to static analysis of the codebase.
448 * Fix memory-safety error in XDR decoding of enumerated types.
452 * Fix reference counting error that could cause an assertion failure
455 * vldb_check -fix will no longer corrupt the vldb when multiple MH blocks are present.
457 * Assorted cleanups and efficiency improvements in the ubik implementation.
459 * Return a valid InlineBulkStatus response in error cases.
461 * The fileserver now rejects invalid partition names when attaching partitions.
465 * Fix volume callbacks (e.g., when running 'vos release').
467 * Treat failure to obtain a DSlot as a hard error for that cache partition,
468 avoiding a flood of "disk cache read error in CacheItems" log messages,
469 and reducing the chance of subsequent panic.
471 * Improve error messages for invalid values with -volume-ttl.
473 * Remove useless error message:
474 "find_preferred_connection: no connection and !create".
476 * Avoid passing NULL to a kernel memory deallocator, which is not guaranteed
477 to be safe on all systems.
481 * Add support for 64-bit ARM clients ("arm64").
483 * Fix panic when cache bypass is enabled.
485 * Improve cache manager behavior when unable to open cache files.
487 * Improvements to the RPM packaging.
489 * Detect out-of-memory when using kernel pages for writing.
493 * Fix various issues in the build process for recent Solaris versions.
497 * Fix clients on OS X 10.13.
499 FreeBSD / NetBSD / OpenBSD
501 * Fix panic triggered during periodic cleanup operations and shutdown.

562 transmit delays when the receive window transitions from closed to
564 - Fix for OPENAFS-SA-2017-001: sanity-check peer transport parmeters
565 received in ack trailers
567 * Libraries (both internal and installed) are built using libtool, including

624 - Convert rpm spec file from deprecated 'make dest' to 'make install'.
625 - Fix rpmbuild command line option default handling.
626 - Support older versions of rpmbuild which do not support the
627 rpmbuild %exclude directive. (12873)
628 - Move the legacy kaserver and related programs to separate sub-packages,
629 which are only built when rpmbuild is given the '--with kauth' option
631 - Package the libuafs perl bindings (12921)
633 * Add a new protection error code (PRNAMETOOLONG) instead of silently
634 truncating names which exceed the maximum name length (PR_MAXNAMELEN).
636 * Add an implementation limit (50000) on the number of names/ids which can
637 be transmitted by unauthenticated clients to the ptserver, avoiding
638 excessive resource consumption from unauthenticated requests.
640 * Add the -config option to vos, pts, and aklog to specify the path to the
641 cell configuration files.
643 * Add more details in vos release -verbose output.
645 * Add the cacheout -encrypt option to encrypt communication between the
646 cacheout client and the fileserver.
648 * Add the command line options to the afsio program to enable encryption of
649 traffic between afsio and the fileserver (-clear, -crypt).
651 * Add the vos release -force-reclone option to force recloning the volume to
652 be released without forcing a full volume dump being transmitted to all
655 * Fix vos to avoid writing loopback addresses into the VLDB in
658 * Print bos and pts error messages to standard error instead of
661 * Improve formatting of the -help output of all commands.
663 * Change -n to -dryrun in all backup subcommands.
665 * Change the backup deletedump -port command line option to -portoffset.
667 * Add user and build host in the version string returned by
670 * Support recent versions of gcc (7.2.1) (12897)
674 * Ubik servers using pthreads are now available and are used by default
676 * As part of improving Ubik reliability in certain edge cases, an extra
677 election cycle (about 60 seconds) may be needed before writes are
678 permitted. This is a conservative change that may be removed in
681 * Avoid continually retransmitting the ubik database to remote sites when
682 a write transaction occurs as remote sites are attempting to rejoin the
683 ubik cluster. (12896)
685 * Ensure the ubik database version number is updated on remote sites at the
686 point the database is transferred to remote sites instead of waiting for
687 the next ubik beacon. This avoids write transaction failures during the
688 window between the database transfer and the next ubik beacon (12885).
690 * Remove periodic background fsync by the fileserver (ihandle fsync thread).
692 * Fix potential file handle leak in the file server ihandle caching layer.
694 * Disable the so-called "hot threads" feature in the file server. The hot
695 threads feature was intended as an optimization for dispatching incoming
696 calls to the current listener thread, but has been reported to incur a
697 performance penalty on modern multi-core systems.
699 * Do not permit creation of users with id of ANONYMOUSID.
701 * Do not save/restore host states in the fsstate.dat file for hosts which
702 are in the process of retrieving CPS information from the ptserver when
703 the fileserver is being shutdown. This fixes a bug in which the fileserver
704 will incorrectly block all threads following a restart.
706 * Add the ptserver -restrict_anonymous option to inhibit exposure of user
707 names from the ptserver.
709 * Do not truncate server log files by default when server processes
710 are started. The -transarc-logs option provides backward compatibility
711 with IBM AFS log handling on server startup. Log messages may be lost
712 in back-to- back restarts when a server is running in this mode.
714 * Reopen server logs on SIGUSR1. This may be used by third-party log
715 rotation tools, such as logrotate, to reopen the log file handles after
716 log files have been renamed.
718 * Fix various bugs when logging with -mrafslogs enabled.
720 * Dynamically reload the kerberos realm to AFS cell mapping (krb.conf) and
721 exclusions for mapping kerberos principals to AFS identities (krb.excl)
722 configuration when the CellServDB cell configuration file is touched.
723 Previously, a restart of the file server was required after updating the
724 kerberos mapping configuration files.
726 * Add a command line option (-restricted_query) to the vlserver and
727 volserver to restrict information queries about volumes to a specific
730 * Add a command line option to the server programs to specify an alternate
731 fully qualified log file name (-logfile).
733 * Add a command line option (-config) to the server programs to specify
734 an alternate path to the server configuration.
736 * Add a command line option to the ptserver and vlserver to specify an
737 alternate path to the database data files.
739 * Add a command line option to the volume server to enable encryption of
740 volume-server-to-volume-server-traffic (-s2scrypt).
742 * Increase the maximum number of LWP threads allowed for the ptserver and
743 vlserver from 16 to 64 (-lwp).
745 * Remove an unused file server command line option (-k).
747 * Fix an incorrect assertion in Demand Attach File Server which could cause
748 the file server process to abort in certain rare conditions.
750 * Deprecate the -bitmap-later configure option for non-Demand-Attach File
753 * Add -vhashsize support to non-Demand-Attach File Servers (DAFS).
755 * Add support for subnet ranges in the NetInfo and NetRestrict
758 * Add the GetXStats RPC to the audit log.
760 * Fix directory creation by bosserver when built for non-Transarc paths.
762 * Fix incomplete list of server addresses retreived by vos listaddr when the
763 vldb contains unreferenced multi-homed server entries.
765 * Remove obsolete bos blockscanner and unblockscanner commands that
766 were only needed for the removed MR-AFS functionality.
768 * Remove obsolete bos salvage options that were only used by the
769 removed MR-AFS functionality..
771 * Remove calls to the deprecated sbrk() function.
773 * Add an experimental feature to database servers to support ubik reads
774 while write transactions are in progress, enabled at build time with the
775 --enable-ubik-read-while-write configure option. This feature is not
776 considered ready for production usage at this time.
778 * Avoid filling the FileLog with "Volume x offline: not in service" when
779 a volume is administratively taken offline with vos offline.
781 * Print an error message when bosserver is started with an unknown
784 * Modify the volume updateDate when the volume is changed by a salvage.
786 * Volume usage statistics are now preserved during reclone and restore
787 operations by default, the behavior previously enabled by
788 the -preserve-vol-stats flag to the volserver. The historical behavior
789 can be retained via the -clear-vol-stats argument.
793 * Use rxkad_crypt by default for connections to fileservers. This matches
794 the existing behavior of the Windows client and has been applied by
795 the distribution packaging on many platforms already.
797 * Add support for relative ACL changes with fs setacl. If a single plus (+)
798 or minus (-) character is appended to the rights' letters argument, the
799 new rights are computed relatively to the existing ones.
801 * Remove afsd -settime and afsd -nosettime support.
803 * Add the afsd -inumcalc option to specify the method used to calculate
804 inode numbers presented by AFS.
806 * Add the afsd -volume-ttl option to specify set the maximum amount of time
807 information retrieved from the vlserver will be cached, regardless of
808 callback expiry times.
810 * Return EIO on internal errors instead of the misleading ENOENT.
812 * Log ICMP errors received, if any, for unreachable servers.
814 * Improve performance of clients with multiple PAGs for different cells.
816 * Fix race condition between changing and using user tokens among cache
819 * Fix fs sysname for users with UID 2748 and 2750 when not running
822 * Add Perl bindings for the user-space cache manager library (libuafs).
824 * Fixes to the bypasscache feature.
826 * Fix fs getcacheparms miscounts.
828 * Remove the obsolete Netscape plugin.
830 * Fix building gtx when ncurses is linked against libtinfo.
832 * Update to the GCO CellServDB update from 14 March 2017.
836 * Remove Linux 2.2 and 2.4 support.
838 * Changes to avoid EIO errors with multiple processes doing intensive mmap
839 writing. (Drop PageReclaim AOP_WRITEPAGE_ACTIVATE.)
841 * Prevent fakestat data inconsistencies in certain cases (131855).
843 * Fix dentry leak which can cause a crash on shutdown.
845 * Fix improper use of ENOENT and avoid incorrect use of linux negative
848 * Use a more correct (less aggressive) scheme to react to downward
849 pressure on cache usage, avoiding d_invalidate(), which can cause
850 getcwd() failures on RHEL 7.4.
852 * Apply a workaround to be compatible with RHEL 7.5's KABI preservation
853 strategy for reading directories.
855 * Improve error reporting when encountering corrupt directories.
857 * Improve rx error handling in the Linux cache manager.
859 * Rename kpasswd to kapasswd when packaging RPMs to avoid colliding with
862 * Do not use the obsolete --enable-largefile-fileservers configure option
865 * In Red Hat packaging, use a separate rpm for kmod debuginfo,
866 removing a needless tight version dependency on the userspace package.
869 * Use the RemainAfterExit systemd feature to avoid premature exit
870 when -afsdb is not given, for RPM packages.
872 * Remove Debian packaging files from the OpenAFS source tree. Debian
873 packaging files are currently maintained in the downstream Debian
876 * Add the sparc_linux26 sysname.
878 * Desupport 32-bit Linux kernels on s390/s390x.
880 * Fix Debian/Ubuntu build regression on kernel 3.16.39.
882 * Fix --enable-kernel-debug for linux 4.8+.
884 * Fix a hang encountered when accessing a previously removed
885 directory entry (12811).
887 * Support linux 4.10, 4.11, 4.12, 4.13, 4.14, 4.15
891 * Remove support for all Solaris and SunOS platforms prior to Solaris 8.
893 * Build 64-bit binaries for Solaris x86 by default.
895 * Use one-group PAGs on Solaris 11, which is required for PAG support
896 on Solaris 11 since supplemental groups must be sorted starting with
899 * Update search paths for solaris cc for recent versions Solaris Studio.
901 * Modernize declaration of module dependences by converting from the
902 deprecated _depends_on symbol to ELF dependencies.
904 * Avoid BAD TRAP panic due to invalid opcodes on x86 with Studio 12.5.
906 * Add ctf debug records to Solaris kernel modules when debug builds
907 are enabled and the ctf tools are present (ctfconvert/ctfmerge).
909 * Save kernel module function arguments on x86 for debugging purposes.
913 * Stop processing upcalls once rx shutdown starts.
915 * Enable atomics for the darwin kernel.
917 * Add a syscall to enable/disable bulkstat at run-time, which is
920 * Fix path to binaries in the prefpane.
922 * Fix builds on MacOS 10.12 by building only the active architecture
925 * Support versions up through 10.13 (High Sierra) and APFS
929 * Use the native kernel module build system instead of an ad hoc
930 replacement build system.
932 * Remove FreeBSD packaging files from the OpenAFS source tree. FreeBSD
933 packaging files are currently maintained in the downstream FreeBSD Ports
936 * Stay up to date with new FreeBSD releases (through 10.3).
938 * Do not claim AFS_VM_RDWR_ENV
940 * Add sysnames and files for i386 and amd64 10.4, 11.1, and 12.0
941 (12-CURRENT, at present). (12887, 12888)
943 * Remove trailing semicolons to fix the build on FreeBSD (12899)
947 * Stay up to date with new NetBSD releases (through 7.x)
949 * Update to use cprng(9) as the randomness source on NetBSD 6.99/7.x.
951 * Build system updates for NetBDS 6.99.x
953 * Do not claim AFS_VM_RDWR_ENV
957 * Stay up to date with new OpenBSD releases (through 4.7)
959 * Do not claim AFS_VM_RDWR_ENV
963 * Updates for AIX support.
965 * Fix build system for AIX exports.
967 * Add the uidpag and localuid runtime options to the aklog LAM plugin.
968 (These runtime options override the use of UID-based PAGs, which were
969 introduced to appease the CDE screensaver.)
975 * Avoid a possible 100ms transmit delay in the RX protocol when a peer's
976 receive window transitions from closed to open (12627)
978 * Documentation improvements (12476 12477 12559[RT #133339])
982 * When bosserver is started with an unknown option, print an error message
983 and exit with a non-zero value rather than failing silently (12631)
985 All DB server platforms
987 * Hold the DB lock while checking for an aborted write transaction (12516)
989 All file server platforms
991 * On demand attach fileservers, don't save or restore a client's host
992 state if CPS ("Current Protection Subdomain") recalculation for it is
993 in progress, to avoid fileserver thread exhaustion (12568)
995 * On demand attach fileservers, avoid flooding the log with error messages,
996 which could happen when the fileserver was restarted while a volume was
999 * Update a volume's "Last Update" time when its content is modified by
1000 the salvager, to make the change visible in the output of "vos examine"
1001 and to backup services (12633)
1003 All client platforms
1005 * Corrected the DCentries bucket counts for very large and zero length
1006 files in the output of "fs getcacheparms -excessive" (12604 12605)
1008 * Fixed a bug that prevented users with GID 2748 and 2750 from executing
1009 the "fs sysname" command on clients running afsd with -rmtsys (12607)
1011 * Provide a new -inumcalc switch for afsd to allow enabling the alternative
1012 MD5 method of inode number calculation, which was previously only
1013 possible on Linux and through the sysctl interface (12608 12632)
1017 * Support for mainline kernel 4.12 and distribution kernels with backports
1018 from it (12624 12626)
1020 * Re-added the improved algorithm for freeing unused vcaches to reduce
1021 memory consumption first introduced with the 1.6.18 release, together
1022 with a fix for the issue leading to its removal in 1.6.18.2 (12448..12451)
1026 * Fixed a crash while stopping the client on macOS 10.12 "Sierra" (12602)
1033 * Build fixes required by recent compilers or platforms (12514 12521 12534
1036 * Allow the bos server to start successfully in the presence of those, by
1037 accepting a now checked return value indicating that the client ThisCell
1038 and CellServDB already exist (12522)
1042 * Support for mainline kernels 4.10 and - most likely - 4.11 and
1043 distribution kernels with backports from them (12530 12588..12590 12598)
1045 * Support for distribution kernels with partial backports from 4.9 (12535)
1048 * In Red Hat packaging, moved the klog.krb5 manual page into the krb5
1051 * In Red Hat packaging, prevent systemd from double-starting the client
1054 * Allow aklog to function on current S390/S390x (12499)
1058 * Make process authentication groups work on Solaris 11, now using a single
1059 group ID (12524..12527)
1061 * Fix a BAD TRAP panic on Solaris 11 clients built with Studio 12.5 (12567)
1065 * Fixed the preference pane for OS X 10.11 and later (12512)
1071 * Build fixes required by recent compilers (12482..12484)
1075 * Support for mainline kernel 4.9 and distribution kernels with
1076 backports from it (12478..12480)
1078 * In Red Hat packaging, make systemd deal correctly with the client
1079 when no userland processes remain after starting it (12481)
1084 * Support for release 10.12 "Sierra" (12431 12432)
1086 * Avoid a crash in the Mounts tab of the OpenAFS preference pane (12447)
1088 OpenAFS 1.6.20 (Security Release)
1092 * Fix for OPENAFS-SA-2016-003: file and directory names leak due to
1093 reuse of directory objects without zeroing the contents
1094 (12461 12462 12463 12464 12465)
1100 * Documentation improvements (12304)
1101 * Fixes for test failures (12396 12415)
1103 All DB server platforms
1105 * Avoid potentially writing to an out of date volume location or protection
1106 database, or losing a database write, which could happen in rare cases
1107 under special conditions during database leader election
1112 * Allow the fsinfo::: DTrace provider to work with AFS files (12371)
1116 * Don't commit more data to a file than was actually copied during writes,
1117 which could happen on architectures with a page size > 4 KiB (12413)
1118 * Fixed build on PPC64 with GCC 6.1 (12388) (RT #133407)
1119 * Fixed build on x86_64 with recent GCC (12365 12366)
1126 * Support for mainline kernel 4.7 and distribution kernels with
1127 backports from it (12348)
1131 * Fixed memory mapped I/O on files >= 4 GiB (12349 12350)
1133 Note that there is a suspicion that this might break the client
1134 on very old Solaris releases (2.6). If it does, the breakage should
1135 occur at build time.
1139 * Added tooling to build a package for OS X 10.10 "Yosemite" and
1140 10.11 "El Capitan" (12335 12351)
1147 * Support for mainline kernel 4.6 and distribution kernels with
1148 backports from it (12332)
1150 * Switch back to the pre-1.6.18 algorithm for freeing unused vcaches.
1151 While the new algorithm is still believed to be correct, it turned
1152 out that at least on some kernels, including 4.5 and 4.6, the dentry
1153 for the current working directory may be erroneously invalidated.
1154 This could lead to errors like "Unable to read current working directory"
1155 when a directory wasn't accessed for a few minutes. (12323)
1157 * Use a secure URL to retrieve the CellServDB in the script to create
1158 the Red Hat source package (12330)
1162 * Added sysname IDs for 10.2 and 10.3 to fix the build on those platforms
1170 * Support for mainline kernel 4.5 and distribution kernels with
1171 backports from it (12300..12302)
1178 * Documentation improvements (12224 11675 11613 12197)
1180 * Improved diagnostics and error messages (12129 12207 12185 12211 12113
1183 * Check that CellServDB entries are valid IPv4 addresses, to avoid
1184 occasional hangs or potentially other erratic behaviour due to invalid
1185 entries (12210) (RT #131794)
1187 All client platforms
1189 * Gracefully handle cases where a client shutdown sequence is initiated
1190 while the client is already shutting down, rather than cause a panic
1193 * Fixed several bugs that could cause erratic behaviour when the write
1194 offset into a file was more than 2 GiB beyond the file's current end
1195 on the server (12213 12214)
1197 All server platforms
1199 * Avoid a possible volserver crash during volume dump or restore due
1200 to invalid ACL entries (12127)
1202 * Allow recovering from a DAFS fileserver operation which allocates a
1203 new vnode but fails to update the vnode index, rather than crashing the
1206 * Fixed a longstanding bug which could damage the volume location database
1207 when "vos changeaddr" was run with "-oldaddr" and "-newaddr" and the
1208 old address was present in a multi-homed entry (12089)
1212 * Added support for releases 10.2 and 10.3 (12232)
1216 * Support for mainline kernel 4.4 and distribution kernels with
1217 backports from it, alas at a performance penalty (12226 12227 12228)
1218 (RT #132677 #132819)
1220 * Avoid using excessive amounts of kernel memory for dynamically
1221 allocated vcaches, by improving the algorithm to free unused ones
1224 * In Red Hat packaging, make the init script use "ip" if available, with
1225 "ifconfig" as a fallback (12193)
1229 * Basic support for release 10.11 "El Capitan" (12212)
1233 * Fixed kernel module builds with optimization (12198) (RT #131261)
1236 OpenAFS 1.6.17 (Security Release)
1238 All server platforms
1240 * Fix for OPENAFS-SA-2016-001: foreign users can create groups as
1241 if they were an administrator (RT #132822) (CVE-2016-2860)
1243 All client platforms
1245 * Fix for OPENAFS-SA-2016-002: information leakage from sending
1246 uninitialized memory over the network. Multiple call sites
1247 were vulnerable, with potential for leaking both kernel and
1248 userland stack data (RT #132847)
1250 * Update to the GCO CellServDB update from 01 January 2016 (12188)
1254 * Fix a crash when the root volume is not found and dynroot is not
1255 in use, a regression introduced in 1.6.14.1 (12166)
1257 * Avoid introducing a dependency on the kernel-devel package corresponding
1258 to the currently running system while building the srpm (12195)
1260 * Create systemd unit files with mode 0644 instead of 0755
1261 (12196) (RT #132662)
1267 * Documentation improvements (11932 12096 12100 12112 12120)
1269 * Improved diagnostics and error messages (11586 11587)
1271 * Distribute the contributor code of conduct with the stable release (12056)
1273 All server platforms
1275 * Create PID files in the right location when bosserver is started with
1276 the "-pidfiles" argument and transarc paths are not being used (12086)
1278 * Several fixes regarding volume dump creation and restore (11433 11553
1281 * Avoid a reported bosserver crash, and potentially others, by replacing
1282 fixed size buffers with dynamically allocated ones in some user handling
1283 functions (11436) (RT #130719)
1285 * Obey the "-toname" parameter in "vos clone" operations (11434)
1287 * Avoid writing a loopback address into the server CellServDB - search
1288 for a non-loopback one, and fail if none is found (12083 12105)
1290 * Rebuild the vldb free list with "vldb_check -fix" (12084)
1292 * Fixed and improved the "check_sysid" utility (12090)
1294 * Fixed and improved the "prdb_check" utility (12101..04)
1296 All client platforms
1298 * Avoid a potential denial of service issue, by fixing a bug in pioctl
1299 logic that allowed a local user to overrun a kernel buffer with a single
1300 NUL byte (commit 2ef86372) (RT #132256) (CVE-2015-8312)
1302 * Refuse to change multi-homed server entries with "vos changeaddr",
1303 unless "-force" is given, to avoid corruption of those entries (12087)
1305 * Provide a new vos subcommand "remaddrs" for removing server entries, to
1306 replace the slightly confusing "vos changeaddr -remove" (12092 12094)
1308 * Make "fs flushall" actually invalidate all cached data (11894)
1310 * Prevent spurious call aborts due to erroneous idle timeouts (11594)
1312 * Provide a "--disable-gtx" configure switch to avoid building and
1313 installing libgtx and its header files as well as the depending
1314 "scout" and "afsmonitor" applications (12095)
1316 * Fixed building the gtx applications against newer ncurses (12125)
1318 * Allow pioctls to work in environments where the syscall emulation
1319 pseudo file is created in a read-only pseudo filesystem, like in
1320 containers under recent versions of docker (12124)
1324 * In Red Hat packaging, avoid following a symbolic link when writing
1325 the client CellServDB, which could overwrite the server CellServDB,
1326 by removing an existing symlink before writing the file (12081)
1328 * In Red Hat packaging, avoid a conflict of openafs-debuginfo with
1329 krb5-debuginfo by excluding our kpasswd executable from debuginfo
1330 processing (12128) (RT #131771)
1332 OpenAFS 1.6.15 (Security Release)
1334 All client and server platforms
1336 * Fix for OPENAFS-SA-2015-007 "Tattletale"
1338 When constructing an Rx acknowledgment (ACK) packet, Andrew-derived
1339 Rx implementations do not initialize three octets of data that are
1340 padding in the C language structure and were inadvertently included
1341 in the wire protocol (CVE-2015-7762). Additionally, OpenAFS Rx in
1342 versions 1.5.75 through 1.5.78, 1.6.0 through 1.6.14, and 1.7.0
1343 through 1.7.32 include a variable-length padding at the end of the
1344 ACK packet, in an attempt to detect the path MTU, but only four octets
1345 of the additional padding are initialized (CVE-2015-7763).
1351 * Support kernels up to 4.2
1353 Due to changes to internal data structures with this kernel release,
1354 the OpenAFS client can no longer reset the link count during path
1355 lookups. Since volume root directories must behave like symlinks
1356 instead of normal directories in order to satisfy Linux kernel
1357 invariants, looking up paths containing more than 40 mount points
1358 will fail with ELOOP on such kernels.
1362 All server platforms
1364 * Prior to the OpenAFS security release 1.6.13, the Volume Location
1365 Server (vlserver) RPC VL_ListAttributesN2() supported wildcard volume
1366 name lookups via regular expression (regex) pattern matching. This
1367 support was completely disabled in 1.6.13 because it was judged to be
1368 a security risk due to buffer overruns in the implementation, as well
1369 as the possibility of denial of service attacks where certain regular
1370 expressions could cause excessive CPU usage in some regex
1373 Unfortunately, after 1.6.13 was released, it was discovered that
1374 the native OpenAFS 'backup' system uses the VL_ListAttributesN2()
1375 regex support to evaluate configured volume sets. If you use the
1376 OpenAFS 'backup' system (or another backup system which relies on it,
1377 such as Tivoli Storage Manager (TSM, aka Tivoli ADSM)), and are using
1378 volume sets which require regular expressions for the volume name,
1379 then those volume sets cannot be resolved by OpenAFS 1.6.13. The next
1380 paragraph provides details on how to identify any affected volume sets.
1382 OpenAFS backup volume sets may be described by fileserver, partition
1383 name, and volume name. The fileserver and partition specifications
1384 never require regular expression support. The volume name specification
1385 always requires regular expression support except for when specifying
1386 _all_ volumes via two special cases: the universal wildcard ".*", or "".
1387 For example, volume name "proj" or "*.backup" or "homevol.*" all
1388 require regex support - even if the specification contains no wildcard
1389 characters and/or exactly matches an existing volume name.
1391 As a result of this issue, OpenAFS 1.6.14 replaces the 1.6.13 changes
1392 to VL_ListAttributesN2. 1.6.14 prevents the buffer overruns and
1393 reenables the regex support, but restricts it to OpenAFS super-users
1394 and -localauth only. This is sufficient to restore the OpenAFS 'backup'
1395 system's ability to work correctly with any previously supported volume
1396 set. The OpenAFS 'backup' commands are already documented to require
1397 super-user authorization, so this restriction is moot for the backup
1400 There are no other direct consumers of the VL_ListAttributesN2() regex
1401 support in the OpenAFS tree. However, the VL_ListAttributesN2 RPC is
1402 publicly accessible and might be used by third party tools directly or
1403 indirectly via OpenAFS's libadmin. Any such tools that issue

1417 All server platforms
1419 * Fix for CVE-2015-3282: vos leaks stack data onto the wire in the
1420 clear when creating vldb entries
1422 * Workaround for CVE-2015-3283: bos commands can be spoofed, including
1423 some which alter server state
1425 * Disabled searching the VLDB by volume name regular expression to avoid
1426 possible buffer overruns in the volume location server
1428 All client platforms
1430 * Fix for CVE-2015-3284: pioctls leak kernel memory
1432 * Fix for CVE-2015-3285: kernel pioctl support for OSD command passing
1437 * Fix for CVE-2015-3286: Solaris grouplist modifications for PAGs can
1438 panic or overwrite memory
1442 All server platforms
1444 * Avoid database corruption if a database server is shut down and then
1445 brought up again quickly with an altered database (11773 11774)
1448 All client platforms
1450 * Fixed a potential buffer overflow in aklog (11808)
1452 * Avoid a bogus warning regarding the checkserver daemon, which could be
1453 logged during startup when the cache initialization was very fast (11680)
1455 * Added documentation of the inaccuracy of the 'partition' field in
1456 'fs listquota' output for partitions larger than 2 TiB (11626)
1460 * Support kernels up to 4.1 (11872 11873)
1462 * Avoid spurious EIO errors when writing large chunks of data to
1463 mmapped files (11877)
1467 * Build fixes required at least on OS X 10.10 Yosemite with the latest
1468 XCode (11859 11876 11842..11845 11863 11878 11879)
1474 * Support kernels up to 4.0 (11760 11761)
1478 * Fixed kernel module build on systems with an updated clang which no
1479 longer accepts the -mno-align-long-strings as a no-op (11809)
1485 * Allow aklog to succeed creating native K5 tokens even when mapping
1486 the K5 principal to a K4 one fails (11538)
1488 * Build fixes (11435 11636)
1490 All client platforms
1492 * Avoid a potential kernel panic due to connection reference overcounts
1493 (11645) (RT #131885)
1495 * Avoid potential corruption of files written using memory mapped I/O
1496 when the file is larger than the cache (11656) (RT #131976)
1500 * Support kernels at least up to 3.19 (11549 11550 11569 11570 11595
1501 11658..11662 11694 11752)
1503 Note: By default this excludes kernels 3.17 to 3.17.2, which will leak
1504 an inode reference when an error occurs in d_splice_alias(). The
1505 module will build and work, but leak kernel memory, leading to
1506 performance degradation and eventually system failure due to
1507 memory exhaustion. Since it's impossible to detect this condition
1508 automatically, the switch --enable-linux-d_splice_alias-extra-iput
1509 must be passed to configure when building the module for those
1510 kernels. The same would be necessary for any kernel with backports
1511 of commit 908790fa3b779d37365e6b28e3aa0f6e833020c3 or commit
1512 95ad5c291313b66a98a44dc92b57e0b37c1dd589 but not the fix in commit
1513 51486b900ee92856b977eacfc5bfbe6565028070 in the linux-stable repo
1514 (git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git) or
1515 the corresponding changes on other branches.
1517 * Fixed a regression introduced in OpenAFS release 1.6.10 which could
1518 make the spurious "getcwd: cannot access parent directories" problem
1519 return (11558 11568) (RT #131780)
1521 * Avoid leaking memory when scanning a corrupt directory (11707)
1525 * Support OS X 10.10 "Yosemite" (11571 11572 11611) (RT #131946)
1529 * Avoid reading random data rather than correct cache content when using
1530 ZFS as the cache file system on Solaris >= 11, and fix potential similar
1531 problems on other platforms (11713 11714)
1535 * Build fix for releases >= 11.0 (11610)
1539 * Support release 5.4 (11700)
1546 * Don't hide the "version" subcommand in help output (11214)
1548 * Documentation improvements (11126 11216 11222 11223 11225 11226)
1550 * Improved diagnostics and error messages (11154 11246 11247 11249 11181
1553 * Build system improvements (11158 11221 11224 11225 11227..11241 11282
1554 11342 11350 11353 11242 11367 11392)
1556 * Avoid potentially erratic behaviour under certain error conditions by
1557 either avoiding or at least not ignoring them, in various places (11008
1558 11010..11065 11112 11148 11196 11530)
1562 * Support releases 9.3 and 10.1 (11368 11369 11402 11403 11404)
1564 * Makes a disk cache more likely to work on FreeBSD, though such
1565 configurations remain not very tested (11448)
1567 All server platforms
1569 * Added volscan(8) (11252..11280 11387 11388)
1571 * Fixed a bug causing subgroups not to function correctly if their
1572 ptdb entry had more than one continuation entry (11352)
1574 * Logging improvements (10946 11153)
1576 * Allow log rotation via copy and truncate (11193)
1578 * Avoid a server crash during startup only observed on a single platform
1579 and when using a 3rd party library under certain circumstances, which is
1580 a collateral effect of the security improvements introduced in OpenAFS
1581 release 1.6.5 (11075) (RT #131852)
1583 All client platforms
1585 * Raised the free space reported for /afs to the maximum possible value of
1586 just under 2 TiB - the old value was 9 GiB on most platforms (10984)
1588 * Reduced the amount of stack space used (11162 11163 11203 11164..11167
1589 11338 11339 11364..11366 11381)
1591 * Sped up a periodic client task which could be problematically slow
1592 on systems with a large number of PAGs and files in use (11307)
1594 * Fixed failure of the up command with large ACLs (11111)
1596 * Avoid a potential crash of aklog (11218)
1598 * Avoid potential crashes of scout and xstat_fs_test (11155)
1602 * Support kernels up to 3.16 (11308 11309)
1604 * Fixed a regression introduced in OpenAFS release 1.6.6 that made
1605 checking for existing write locks incorrectly fail on readonly volumes
1608 * Fixed a regression introduced in OpenAFS release 1.6.8 that could
1609 cause VFS cache inconsistencies when a previously-accessed directory
1610 entry was removed and recreated with the same name but pointing to a
1611 different file on another client (11358)
1613 * Use the right path to depmod in Red Hat packaging to avoid dependency
1614 calculation incorrectly failing unless a link /sbin -> /usr/sbin is
1615 present on the system performing it (11171) (RT #131860)
1617 * Do not ignore kernel module build errors (11205)
1621 All server platforms
1623 * Fix for OPENAFS-SA-2014-002
1629 * Documentation improvements (10751 10875 10931 10897 10883 10954 10955)
1631 * Improved diagnostics and error messages (10756 10814 10949)
1633 * Fixed a bug in RX that could make errors during packet reception go
1636 * Fixed a bug that made "vos size -dump" display the wrong size for
1637 large volumes. (10933) (RT #131819)
1639 All server platforms
1641 * Change the default fileserver sync behavior from "delayed" to "onclose".
1642 This means that explicit syncing only happens when a volume is detached.
1645 * Added the -offline-timeout and -offline-shutdown-timeout options to the
1646 fileserver, to implement interrupting clients accessing volumes we are
1647 trying to take offline. (6266 10799)
1649 All client platforms
1651 * When a client is shut down, it will give up its callbacks. The Windows
1652 client has been doing this since 2007. Note that older fileservers
1653 (1.3.50 to 1.4.5 and 1.5.0 to 1.5.27) had a bug in the implementation of
1654 the relevant RPC that could cause crashes or other undefined behavior
1655 when this happens. (6272 8840 10855)
1657 * Restored the pre-1.6 behavior of "vos e" being an alias for "vos examine".
1660 * Avoid flooding logs with warnings about byte-range locks, by throttling
1661 them per file. Also, make the messages more useful by including the
1664 * Avoid a possible panic during shutdown while tracing. (10932)
1668 * Fixed a bug that could cause the "getcwd: cannot access parent
1669 directories" problem (10804 10984)
1671 * Avoid a delay when accessing uncached data in AFS in a confined
1672 context under SELinux. (10598)
1674 * Red Hat packaging improvements (10600 10767 10807)
1678 All server platforms
1680 * Fix for OPENAFS-SA-2014-001
1682 * Fix for a potential DOS attack against RX servers
1688 * As of this release, OpenAFS no longer ships uncompressed source tarballs.
1689 Tarballs are still shipped with both compression formats, gzip and bzip2.
1692 * Documentation improvements (10136 10314 10601)
1694 * Improved diagnostics and error messages (9412 10085 10274)
1696 * Avoid redefining "assert" in our public header files, which could
1697 cause failures when building some applications using them. (10096)
1699 * Fixes for parallel builds (10005 10309 10337)
1701 * Added a -s switch to afscp (not installed by default) to help simulate
1702 a slow client. (9416 9417)
1704 * Added a -probe switch to vlclient test program (not installed by default)
1705 to ping all vlservers in a cell in parallel. (9570)
1707 All server platforms
1708 * The fileserver now ignores any vice partitions with a NeverAttach flag
1709 file present in the root directory. (RT #130561) (9470 9471)
1711 * Restrict forcing CPS ("Current Protection Subdomain") recalculation in
1712 the fileserver to administrators. Also fixed a bug that could cause this
1713 operation to be incomplete. (9485 9487)
1715 * Allow non-DAFS fileservers to attach unusable volumes, restoring pre-1.6
1716 behaviour. (RT #131505) (9499)
1718 * Restored the pre-1.6 behaviour when running vos examine for a volume
1719 currently in a transaction, showing the volume as busy again rather than
1720 offline. (9685 9915 9916)
1722 * Reduced the minimum time a bos salvage takes from 5 seconds to 1. (9476)
1724 * Fixed buserver to not segfault when started with the -servers option.
1725 (RT #131706) (10166)
1727 * Salvager fixes, addressing a wide variety of possible problems from
1728 unnecessary salvaging to aborts (9282 9283 9457 9458 9459 9461 9462 9480
1731 * Fixed a bug that could cause saved state information to be discarded
1732 when restarting a large or busy fileserver, which negatively impacted
1735 * Fixed a bug that could have caused undefined behaviour in the vlserver
1736 in rare cases when a fileserver registered its addresses in the VLDB.
1739 * Added the -preserve-vol-stats switch to volserver, allowing it to keep
1740 the access statistics across volume restore and reclone operations
1741 instead of resetting them. (9477)
1743 * Inserted an exponential delay between retries when bosserver attempts to
1744 restart a server process. (9571 10199)
1746 * Improved vldb_check (not installed by default) to cope with broken
1747 vlentry names and volids, and provide more output to aid debugging.
1750 * Releasing a volume after adding a new RO site no longer touches any of
1751 the existing RO sites, if the RW data hasn't changed since the last
1754 * Make the copyDate field for RO clones have the same meaning as for
1755 remote RO volumes. Previously, the copyDate field for clones was updated
1756 every time we released. (9451)
1758 * Fixed potentially undefined behaviour in ptserver when too many pts
1759 ids are allocated. (10124)
1761 * Note that the server side NAT pings feature present in the prereleases
1762 was removed before the final release, since no positive feedback
1763 was provided during prerelease testing. (9420 10135)
1767 * Start bosserver with -nofork in the systemd unit file, to allow systemd
1768 to track its state (10093)
1770 All client platforms
1772 * No longer track file locks on read-only volumes. Write locks can't
1773 succeed, read locks always will. Avoids log messages about this kind
1776 * Added the "fs flushall" subcommand, which makes the client discard all
1777 cached data. This was previously available on Windows only. (9065 9388
1780 * Fixed a bug that could make the client incorrectly believe its cache
1781 is up to date. This change could negatively impact AFS <-> DFS
1782 translators, should those still be running anywhere. (8898)
1784 * Several changes to avoid panicing in certain error conditions.
1785 (9131 9287 10354 10355 10356 10357) (partially addressing RT #131747)
1787 * Added the -rxmaxfrags switch to afsd, allowing to limit the number
1788 of UDP fragments sent or received per RX packet. (9430)
1790 * Build fixes for aklog on several platforms (RT #131716) (9917 10107 10275)
1792 * Require that the AFS mountpoint specified in the cacheinfo file is
1793 an absolute path. Relative paths result in a client that basically
1794 works but is not fully functional. (10253)
1796 * Fixed a bug that could cause one of the afsd threads to enter an infinite
1797 loop (10431 .. 10436)
1801 * Support Linux kernels up to 3.13 (10241)
1803 * Fixed a bug that made readv/writev calls in AFS space fail with Linux
1804 kernels where generic_file_aio_read exists but those operations have
1805 not been switched to using aio_read/aio_write. This was a regression
1806 introduced with release 1.6.3 and affected at least RHEL 5.9 kernels.
1809 * Fixed a similar bug making core dumps fail in AFS space, affecting
1810 a much wider range of kernels including the most recent ones.
1811 (RT #131729) (10254)
1813 * Enhanced the keyring code to make PAGs work correctly on kernels with a
1814 distribution specific change to the Linux keyring code. This affected at
1815 least SLES 11 SP3 kernels. (10252)
1817 * Fixed a bug that could make failures during PAG instantiation go
1820 * Fixed a bug that made compilation fail for Linux kernels without
1821 keyring support. This affected at least the SLE 10 SDK and an
1822 OEM version of SLES 11 SP1. (10325)
1824 * Fixed build for kernels with user namespace support enabled. Likely
1825 to be required for Ubuntu 14.04 and eventually other distributions.
1826 (10456 10457 10458 10518 10472)
1828 * Support RHEL 6.5 kernels, and possibly others with changes backported
1829 from recent mainline kernels that touch getname/putname, by no longer
1830 using those functions. Previously, the client could cause a kernel
1831 panic when syscall auditing was enabled. (10578)
1833 * Make tmpfs usable as the cache filesystem again. This had been broken
1834 since kernel 3.1 (9950 10193)
1836 * When starting the client fails, clean up the backing device information
1837 created in sysfs, to avoid error messages during a subsequent start
1838 and possible system instability later on (10454)
1840 * Update Red Hat packaging to support Fedora >= 20, RHEL >= 7 and
1841 ELrepo kernels (10597 10619 10622 10703 10704)
1845 * Support OS X 10.9 "Mavericks" (10519 10541 10542 10543 10548 10549)
1849 * Fixed a bug that caused the 1.6 AIX client to never receive any RX
1850 packets in the kernel. (RT #131725)
1854 * Support Solaris 11 (9454 9455)
1856 * Allow other users to access filesystems mounted by root. (9452)
1860 * Build tvolser and dvolser on this platform (10122)
1861 * Several fixes to catch up with newer releases (10374 .. 10381)
1865 * Build tsalvaged, tvolser and dvolser on this platform (10121)
1866 * Fixed build on NetBSD 5 and newer. (10138)
1872 * Fixes for OpenAFS-SA-2013-0003 and OpenAFS-SA-2013-0004
1878 * Obey the jumbo/nojumbo settings for ubik servers (the DB servers)
1879 too. In previous releases, those servers may have used jumbograms
1880 even if they were not configured to do so. This change corrects
1881 the actual behaviour, and will improve performance and reliability
1882 for sites where jumbograms are problematic. It could cause a decrease
1883 in performance for sites where jumbograms work, but those can turn
1884 them back on manually.
1886 * Dozens of fixes for common coding problems like use after free,
1887 use of possibly uninitialised memory, reading or writing past the
1888 end of arrays and potential NULL pointer derefences. Spotted by
1889 code analysis tools or human inspection.
1891 * Documentation improvements.
1893 * Fixes and improvements to the diagnostic or log messages printed by
1894 vos, the fileserver and others.
1896 * Build fixes, making parallel builds more reliable with certain
1897 configuration options and helping various platforms including
1898 recent releases of IRIX, Solaris and several flavours of Linux.
1900 * Avoid sending a small amount of data over the wire unencrypted
1901 under certain conditions, and emit the correct error message in
1904 All server platforms
1906 * Avoid generating duplicate IDs for readonly and backup volumes,
1907 which could happen under certain conditions.
1909 * Allow the fileserver to return volume data like quota or free space,
1910 which is available publicly elsewhere, without the additional access
1911 check for read permissions on a volume's root directory the fileserver
1914 * The fileserver now emits a log message when it ran out of memory for
1917 * Avoid several potential fileserver problems, including memory
1918 corruption and segmentation faults, due to client bookkeeping.
1920 * Avoid known cases of silent data corruption due to background syncs
1921 on the fileserver, especially during Copy on Write.
1923 * Make the fileserver sync behaviour runtime configurable. Up to 1.4.5,
1924 we had synchronous syncs which were safe but really slow. Since 1.4.5,
1925 we've had asynchronous syncs which are much faster but believed to
1926 be the cause of rare data corruption issues, and while all known cases
1927 of these happening are believed to be fixed in the 1.6.3 release, doubts
1928 remain. This change allows choosing between those, and in addition allows
1929 to turn syncs by the fileserver off altogether, thus relying on the vice
1930 partition's backend filesystem and the operating system, or to just
1931 execute them when a volume is detached. The default behaviour is
1932 unchanged from releases since 1.4.5, but it's highly recommended to
1933 consider the additional options this change provides. Future OpenAFS
1934 releases will default to "-sync=none".
1936 * For dbservers, avoid a situation where misinterpreting transient
1937 network errors causes long-term issues with achieving ubik quorum.
1939 All UNIX client platforms
1941 * Improvements to the detection of an aklog-specific krb5 configuration
1942 file, for the purposes of turning on "weak crypto" for aklog.
1944 * Fixed a regression introduced in release 1.6.2 which caused the
1945 supposedly persistent disk cache to be discarded upon client start.
1950 * Support Linux kernels up to 3.10
1952 * Fixed two bugs making it impossible to unmount a disk cache filesystem
1953 after it has been used by the client. (RT #131613)
1955 * Fixed a bug that could cause an oops with kernels 3.6 and later
1959 * Improved support for OpenBSD 4.9 to 5.3
1963 This release number had to be skipped for technical reasons.
1969 * Support Linux kernels up to 3.8.
1971 * Make the init script cope with the output of ifconfig on recent Fedora.
1977 * Fix buffer overflows in fileserver and ptserver.
1979 * Abort an rx connection when given an unknown service (Gerrit 7593).
1981 * "idle dead" behavior improvements.
1983 * Documentation updates.
1985 All server platforms
1987 * Fix rare file corruption during background sync (Gerrit 8796).
1989 * Fix corrupting clients' metadata cache during certain errors (Gerrit
1992 * Avoid saying a volume doesn't exist when accessed as the volume is
1993 going offline (Gerrit 7488).
1995 * Fix fileservers to properly report >2 TiB partitions.
1997 * Fix stale volume info from vos examine on non-DAFS filservers.
1999 * Fix possible volume corruption with vos convertROtoRW.
2001 * Fix bosserver to preserve all command-line options over restart.
2003 * Fix bosserver to properly kill hung processes during shutdown.
2005 All UNIX client platforms
2007 * Fixes for memcache, especially on Solaris.
2009 * Increase the size of the DNS resolver answer buffer to allow sites
2010 with a long response list to use SRV and AFSDB records.
2012 * Fix a crash when a server appears to run out of addresses (Gerrit
2015 * Fix cache corruption when reading from a file another client is
2016 simultaneously writing to (Gerrit 7994).
2018 * Improve handling of disk cache disk errors.
2022 * fix DKMS configuration for DKMS 2.2.
2024 * Avoid generating inode number 0 with md5 inodes (Gerrit 7276).
2026 * Fix a crash when reading /proc/fs/openafs/unixusers (Gerrit 7914).
2028 * Make PAG-less access use the real UID of the calling process
2029 instead of the effective UID, when determining what credentials to
2032 * Fix possible abuse of fs mkmount.
2033 Prior to 1.6.2, users could crash a client by nesting volume mounts.
2035 * Fix fileserver memory corruption on RHEL 6
2036 Prior to 1.6.2, fileservers on RHEL 6 may crash under heavy load.
2038 * Fix client page cache corruption on Linux
2039 When multiple clients read and write to a file, the reading client
2040 may see first page (4096 bytes) of a file as nulls.
2042 * Support Linux kernels up to 3.7.
2044 * Support newer glibc versions.
2046 * Improve client systemd unit file.
2048 * Update Red Hat packaging.
2052 * Fix crashes on shutdown.
2054 * Prevent unloading the module before shutdown completes.
2056 * Security improvement for the OpenAFS preference pane.
2060 * Support newer versions of the Sun Studio compiler software.
2062 * Support compiling on newer versions of Solaris 11 and Solaris 10.
2065 OpenAFS 1.6.0 (2011-08-15)
2069 * Substantial Rx updates to correct erroneous behavior.
2071 * vos now properly deals with matching sites when servers are

2110 * Fix ptserver supergroups support on 64 bit platforms.
2112 * Demand attach salvaging doesn't use freed volume pointers.
2114 * Properly hold host lock during host enumeration in fileserver.
2116 * Attempt to recovery more quickly from timed out volume release
2119 * Auditing now properly byte order swaps IP addresses when printing.
2121 * vos split now has improved error handling.

2131 * Fix support for large (greater than 2gb) volume special files.
2133 * Salvager will not crash if multiple or bad volume link tables are
2136 * Avoid erroneous full dump by remembering which sites were out of
2137 date at the start of the release.

2171 if the checkbox is not present in the dialog. (128591)
2173 * AFS Explorer Shell Extension now works from folder backgrounds.
2174 Overlays for mount points and symlinks are present in the dll, but
2175 are not registered at present by the installers.

2178 PerformanceTuningInterval.
2180 * When the data version of a mountpoint or symlink changes, the target
2181 string in the cm_scache_t object must be cleared.
2183 * "fs checkservers" now includes vldb servers in the output and only
2184 lists multi-homed servers once. A multi-homed server that has at
2185 least one up interface is no longer considered to be down.
2187 * When asynchronously storing dirty data buffers to the file server
2188 ensure that (a) the cm_scache_t object and the cm_buf_t object are
2189 for the same File ID so that locking and signalling work properly;
2190 and (b) if the FID no longer exists on the file server, do not
2191 panic, just discard the buffer.
2193 * When processing VNOVOL, VMOVED and VOFFLINE errors perform server
2194 comparisons by UUID or address and not simply by cm_server_t

2205 * Race conditions were possible when updating the state of the
2206 cm_volume_t flags and when moving the volumes within the least
2209 * Ensure that the lanahelper library does not perform a NCBRESET of
2210 each lan adapter when enumerating the current network bindings.
2211 Correcting this permits OpenAFS to work on Windows 7 when the
2212 network adapter settings change.

2222 * Fix caching of non-existent volumes. The test to trigger an
2223 immediate CM_ERROR_NOSUCHVOLUME in cm_UpdateVolumeLocation() was
2226 * Prevent the background daemon from checking the status of
2227 non-existent volumes. cm_CheckOfflineVolumes() should skip volume
2228 groups with the CM_VOLUMEFLAG_NOEXIST flag set.
2230 * The afskfw library should return an error immediately if the
2231 krb5_32.dll library cannot be loaded. Affects afslogon.dll and
2234 * No longer depend on leashw32.dll in afskfw library.
2236 * NPLogonNotify must provide the user password in all calls to
2237 KFW_AFS_get_cred(). It cannot count on a credential cache being
2238 preserved between calls. Permits tokens to be acquired for all
2239 cells listed in the TheseCells registry value for a domain.
2241 * Improve the trace logging from NPLogonNotify().
2243 * Avoid a race when writing the cm_scache_t mountPointString
2244 when acquiring mount point or symlink target data via
2245 cm_GetData(). The race could result in bogus target
2248 * Permit the use of des-cbc-md5 and des-cbc-md4 enctypes
2249 as DES keys in asetkey.exe.
2251 * aklog supports dotted Kerberos v5 principal names.
2253 * afskfw library always attempts afs/cell@USER-REALM
2255 * afskfw library must test return code from krb5_cc_start_seq_get() or
2256 will trigger a null pointer exception when using Heimdal.
2258 * Lock protected fields must be 32-bit in order to avoid memory
2261 * Add support for NTFS symlinks.
2263 * Handle file search requests for virtual syscall ioctl file.
2265 * Process SyncOps properly to enforce ordered operations.
2267 * Avoid recursing during NewServer operations.
2269 * Correct lock acquisition order during SMB locking.
2271 * Add shutdown message to event log.
2273 * Check offline volume status by policy rather than on each daemon
2276 * Return error on directory object not found instead of crashing.
2278 * Improve error message output.
2280 * afslogin.dll can start afsd_service if it's not starting or started.
2282 * Optimize away release lock RPCs for deleted files.
2284 * Background Daemon will not perform operations on deleted files.
2286 * Resort recently used directories to the top of the LRU if the
2287 directory is larger than the stat cache.
2289 * Resort deleted objects to the bottom of the LRU.
2291 * Use interlocked operations for state and queue fields to allow safe
2292 bit set and clear on multiprocessor systems.

2312 * Deal with libcom_err conflicts with other packages using it
2313 (e.g. krb5) (128640)
2315 * Fall back to afs3-vlserver SRV record values when afs3-ptserver SRV
2316 record is not available.
2318 * Avoid holding unneeded locks when probing server capabilties.
2320 * Do not attempt page flushes for directories.
2322 * Rx connection reference counting is enabled.
2324 * An Rx connection reference count leak is fixed in bulkstat.

3589 discrepency between the mask used for testing for readonly behavior
3590 and that used for setting the attribute.
3592 * Disable AFSVolSync based .readonly "whole-volume callback" support
3593 because the all file servers prior to 1.5.67 (and perhaps 1.4.12) do
3594 not properly assign a value to the AFSVolSync structure in bulk
3595 status RPC responses.
3597 * Improve the error output from aklog to output the value from krb5
3598 error_message() if the afs_com_err output indicates an unknown

3720 * Adjust SMB error return codes to avoid returning STATUS_TIMEOUT
3721 which results in the SMB redirector disconnecting.
3723 * Network Identity Manager OpenAFS Provider now provides its own "AFS
3724 lock" notification icon to report the status of "have tokens, have
3725 no tokens, service not started, service started but inaccessible".
3726 Hovering over the icon lists the cells for which tokens exist (if

3730 * Prevent pioctl calls from retrying indefinitely when a sharing
3731 violation error occurs.
3733 All UNIX client platforms
3735 * Correct a condition which could discard the error from initializing

3793 being returned as part of a fetch data response if the client
3794 attempts to read beyond the length of the file.
3796 * Do not publish a default stream object for directories and mount
3797 point objects. This was impacting the ability of some Windows XP
3798 systems to save roaming profiles.
3800 All UNIX client platforms
3802 * A bug which could cause erroneous handling of lengths on data reads
3805 * A bug where erroneous length returns from the fileserver could

3839 * The demand attach fileserver had a structure reference error, which
3840 has been correected.
3844 * Restores Windows 2000 compatibility.
3846 * Fixes a data consistency error between the output of NetWkstaGetInfo
3847 and NetServerGetInfo RPCs, specify the Lan workstation group name
3848 "AFS", and report server name as "AFS" instead of "\\AFS" when the
3849 caller asks for "\\AFS".
3851 * Enables executables to be run from \\AFS on Windows 7. Returns
3852 "Name not found" instead of "File not found" when a directory or
3853 file name cannot be found. This avoids loader errors when system
3854 dlls cannot be located in the executable directory.
3856 * Prevents cache manager from marking the file server "down" when the
3857 data returned in response to either RXAFS_FetchData64 or
3858 RXAFS_StoreData64 is invalid.
3860 * Adds pioctl data validation to the AFS Explorer Shell extension.
3862 All UNIX client platforms

3888 format when handling them in all cases.
3890 * Documentation now refers to Kerberos instead of kaserver.
3892 All server platforms
3894 * bosserver now handles BosConfig.new when restarting, allowing
3895 configuration to be replaced at restart time rather than with bos
3896 delete and bos create. Documentation is updated to reflect this.
3898 * The demand attach fileservice not longer potentially hangs trying to
3899 terminate demand-salvages which have already exited.
3901 * The demand attach fileservice has been modified to avoid spurious
3902 'SYNC_putRes: write failed' warnings when some protocol messages
3903 cannot be acknowledged due to the sender terminating the connection.
3905 * In the event of failure to contact the vlserver or ptserver, the
3906 fileserver will not exit and trigger a forced salvage. It will
3907 continue to try in the background to contact the needed services.
3909 * The salvager can now repair certain cases of a damamged vnode index.
3911 * The accessDate metadata for a volume is now updated correctly.

3917 also experienced inconsistent behavior. This is fixed.
3919 * CRITICAL: Multiple AFS pioctl requests issued nearly simultaneously
3920 by applications could result in pioctl responses being received by
3921 the wrong requester. This in turn could result in application
3922 crashes. symlink.exe, fs.exe, afslogon.dll, afscreds.exe, and the
3923 netidmgr afscred.dll plugin were all affected.
3925 * Some XP machines running 1.5.62 had trouble saving roaming profile
3926 data. This is fixed.
3928 * Integrated Logon (afslogon.dll) did not function with domain
3929 specific configurations.
3931 * Ensure that access denied and over quota errors experienced while
3932 storing data to the file server do not result in on-going retry

3938 configure time by setting the CC environment variable.
3940 * afsd now properly deals with large cache partitions.
3944 * Build shared libafsauthent and libafsrpc.
3948 * Kernel module DKMS support now installs an unstripped module to

3958 with an AFS string to key on hosts able to run 64 bit binaries.
3960 * A panic at AFS shutdown due to "NO PCB" on a udp_lock has been
3963 * The panic decoder script included in the source now properly handles
3964 32 and 64 bit panics.
3968 * Avoid defining AFS_KERBEROS_ENV globally as it creates a circular
3971 * Build shared libafsauthent and libafsrpc.
3975 * Build shared libafsauthent and libafsrpc.
3978 OpenAFS 1.5.62 (2009-08-28)
3982 * Numerous invisible changes to improve code maintainability,
3983 portability and enhanceability.
3987 * CRITICAL: Fixes two errors that can result in data loss when storing
3988 data to the file server.
3989 1. Failure to Store Portions of Unaligned Writes
3990 2. Failure to Store Data to File Servers Lacking Large File Support
3991 Read the announcement for more details:
3992 http://www.openafs.org/pipermail/openafs-announce/2009/000305.html
3994 * CRITICAL: The cache manager daemon thread could terminate when the
3995 machine enters suspend mode. This daemon thread performs the
3996 background check of down servers, offline volumes, callback
3999 * CRITICAL: Integrated Logon (afslogon.dll) was terminating
4000 unexpectedly. Error checking has been improved and NULL pointer
4001 dereferences after Lsa API calls fail have been eliminated.
4003 * For the first time, the OpenAFS SMB Server supports the DCE RPC
4004 services SRVSVC and WKSSVC. Browsing \\AFS with the Explorer Shell
4005 or NET VIEW will now be faster and provide additional functionality.
4006 No longer will cell names longer than 12 characters be truncated.
4008 * Improvements to DFS Referral request processing have been
4011 * Unnecessary DNS lookups of share names are avoided improving
4014 All UNIX client platforms
4016 * Non-Kerberos PAM modules work correctly again.
4020 * MacOS 10.6 (Snowleopard) is now supported, both 32 and 64 bit mode.
4022 * Updates to the AFSCommander preferences pane.
4024 * Installer now permits cell names with dashes.
4027 OpenAFS 1.5.61 (2009-08-06)
4031 * Correct another race condition in the Rx library that could result
4032 in an unexpected panic while freeing the Rx call iovq.
4034 * rx packet resend and data packets sent counts were incorrect.
4036 * fs setquota, fs setcachesize, vos setfields, and vos create now
4037 accept human readable orders of magnitude. (K, M, G)
4039 * fs listquota fixed to permit large quota sizes to be displayed.
4041 * Correct documentation of bosserver permissions requirements.
4043 * Modify vlserver to avoid potentially corrupting the database through
4046 * Generalized support for fast Rx timeout due to network
4049 All server platforms
4051 * Allow audit logs to be sent via sys5 IPC message queues instead of
4056 * If a file server becomes inaccessible while the cache manager has
4057 dirty buffers to write, the afsd_service buf_IncrSync thread can
4058 attempt to use 100% of the cpu.
4060 * Fix "fs newcell" which was broken in 1.5.60.
4062 * Do not attempt to synchronize dirty buffers if the associated volume
4063 is known to be unavailable.
4065 * Modify behavior of a Freelance mountpoint target that does not
4066 specify a cell. Instead of assuming the target volume is in the
4067 Freelance.Local cell, use the workstation "Cell" specified in the
4068 registry. A mountpoint target of "#root.cell." will now mean the
4069 root.cell volume in the workstation cell for the current session.
4070 If the workstation cell changes from "athena.mit.edu" to
4071 "andrew.cmu.edu", the referenced volume will also change without
4072 requiring that the mount point targets be altered.
4074 * Add cm_FindServerByUuid(). Re-implement RXAFS_InitCallBackState3()
4075 to permit the server Uuid to be used to lookup the server object and
4076 from that determine the cell. This permits callbacks that are
4077 received from alternate addresses to be processed with a known
4078 server object. Previously a request from an unknown server would
4079 clear all callbacks from all cells.
4081 * Fix a bug that prevented optimal performance when using a non-zero
4082 value for 'daemonCheckVolCBInterval'. As a reminder, when
4083 "daemonCheckVolCBInterval" is set to a non-zero value, all .readonly
4084 volume callbacks are automatically renewed 90 minutes before their
4087 * Fix automatic ranking of vldb servers whose values are obtained from
4088 the CellServDB file.
4090 * Add failover for RX CALL TIMEOUT errors when the volume is readonly
4091 or the call is to a vldb server.
4093 * Add registry based cell search functionality to NetIdMgr,
4094 afs_config.exe, and klog.exe.
4096 * afsconf_GetCellInfo() has been modified to perform gethostbyname()
4097 lookups on the host names in the CellServDB instead of using the
4098 specified IP addresses. This provides aklog, pts, vos, etc. the
4099 same CellServDB behavior that the Windows Cache Manager uses.
4101 * When updating the stat cache entry callback of a .readonly object
4102 from the volume group object, update the file server reference to
4103 ensure it matches the most update to date callback.
4105 * Add proper support for processing callbacks from multi-homed file
4106 servers. Instead of comparing servers by cm_server_t pointer,
4107 compare them by UUID when the UUID is known.
4109 * During a shutdown short circuit the offline volume check daemon
4112 * Return the error code of RXAFS_FetchData / RXAFS_StoreData in
4113 preference to an error code reported by rx_EndCall.
4115 * Add "PerFileAccessCheck" registry value to permit testing against
4116 experimental file servers that include per-file acl support. This
4117 value is intentionally undocumented. It is not to be used by
4118 production environment deployments.
4120 * Fix a bug introduced in 1.5.60 that prevents the afs netidmgr
4121 provider from obtaining tokens when referrals are in play.
4123 * Add "fs chown" and "fs chgrp" commands to permit the owner and group
4124 of objects stored in AFS to be set from Windows.
4126 * Avoid performing background daemon operations when the machine is
4127 going into suspend mode.
4129 * Perform offline volume checks in most recently used order.
4131 * Prevent crash when a data version for a cache object goes backwards.
4133 * Multi-thread safe library versions are now being generated and used.
4134 mtafsubik.lib, mtafsutil.lib, mtafsvldb.lib, mtafsvol.lib.
4136 * Microsoft SMB Redirector (mrxsmb.sys) support for
4137 ExtendedSessTimeout values are now available on XP through Windows
4138 7. Add functionality to autodetect if such support is present on
4139 the machine. If so, configure it if necessary and dynamically
4140 adjust the AFS Rx timeout values accordingly.
4142 All UNIX client platforms
4144 * Fix out-of-tree source builds.
4148 * GUI installer now asks for local cell information.
4150 * AFS Commander preferences pane is now installed by default.
4154 * Avoid kernel panics due to null pointer dereferences in the network
4155 interface poller kernel thread.
4158 OpenAFS 1.5.60 (2009-05-31)
4162 * Retry volserver transaction creation on failure.
4164 * Allow building HTML and PDF documentation from included XML copies
4165 of User Guide, Admin Guide and Quick Start Guide for Unix.
4167 * Documentation updates and additional documentation.
4169 * Add -encrypt support to pts client.
4171 * Convert MR-AFS fs commands to OSD commands.
4173 All server platforms
4175 * Updated background sync process in fileserver to avoid a race which
4176 could result in a volume being taken offline.
4180 * On April 9th Microsoft released a Hot Fix for Windows Server 2003
4181 SP2 that corrects a deadlock in the smb redirector and also adds new
4182 functionality that permits the AFS SMB server to be given a longer
4183 timeout than is normally the case. New functionality has been added
4184 to configure these additional LanmanWorkstation\Parameter values.
4185 (This functionality has been backported to XP SP3 and is scheduled
4186 to be released on June 5th.)
4188 * Fix RT#124787, a race condition between "fs flush <dir>", "fs
4189 flushvolume", or "fs flushall" and on-going directory operations
4190 that can result in afsd_service.exe crashing.
4192 * Release Notes, User and Administrator guides are now shipped as
4193 indexed Windows HtmlHelp Files. (.chm). Shortcuts are provided from
4196 * A method of specifying Client CellServDB information within the
4197 registry has been added that can be used to either override the
4198 CellServDB file or force the use of DNS lookups for a given cell.
4199 See the release notes for details.
4201 * The pioctl interface now properly handles drive letter substitution
4202 to UNC paths. (SUBST <d:> <\\afs\cell\path>)
4204 * The BackConnectionHostNames registry value configuration was broken
4205 when dynamic re-establishment of Netbios Name registrations was
4206 added. This release restores the functionality.
4208 * All hidden vos.exe commands are now revealed.
4210 * Attempts to store the same dirty file chunk from multiple threads
4213 * The IsPathInAfs test in Explorer Shell Extension and fs.exe now
4214 permits broken symlinks to be treated as being in AFS.
4216 * vos.exe commands that output 64-bit integer values once again do so.
4217 This was broken in 1.5.59.
4219 * Cygwin Import Libraries are provided in the SDK for all OpenAFS
4220 DLLs. This permits building cygwin applications against OpenAFS
4223 * NSIS installer does a much better job of cleaning up files left over
4224 from previous installs.
4226 * libafsconf.dll moved from Client\Program to Common directory as is
4227 is now used by all modules for CellServDB processing.
4229 All UNIX client platforms
4231 * Write back changes on last store for memcache to avoid discarding
4234 * Abstract disk cache support to allow for path, fh, inode based
4235 caches with no need for messy ifdef structures each time a new type

4320 * [RT 124293] A race condition exists which can result in a crash.
4322 * [RT 124276] If the vldb is out of sync with the contents of the file
4323 servers, afsd_service will retry too many times when a file server
4324 reports a volume as not being present. Now if the list reported by
4325 the vldb is the same as the previously seen list, then the retry is
4328 * [RT 124276] Read-only volume failover was broken in 1.5.53 whenever
4329 accessing a volume results in VNOVOL or VMOVED.
4331 * [RT 124276] Prior to 1.3.70 the volume server reference list was not
4332 reference counted and would be prematurely freed while in use. When
4333 reference counting was added in 1.3.70 a bug was introduced that
4334 could result in service reference list corruption.
4336 * Add Windows Application Event Log warning messages for "Client SMB
4337 MPX value too large" and "Client SMB Buffer Size too small".
4339 * Renaming of files across directory boundaries would result in an
4340 invalid handle error when attempting to access the files after the
4343 * Fix the handling of Tran2 Set Path Info RPCs. Do not fail when a
4344 smb file descriptor cannot be found. The whole point of using a
4345 Path Info function is because an smb file descriptor wasn't
4348 * More edge cases in which dynamic addition of Freelance root.afs
4349 entries would get the wrong FID or where the root.afs directory
4350 would not be refreshed.
4352 * Buffer overflow could occur if the workstation cell name was longer
4353 than 64 characters. Crashes could occur in afscreds.exe,
4354 afslogon.dll, and afsd_service.exe.
4356 * VNOSERVICE and VOFFLINE errors were leaking and were exposed to the
4359 * Log file server uuid values as part of the cm_server object when
4360 available. Dump the cm_server object list in response to "fs
4363 * Optimize the performance of resetting access control lists when

4501 * butc XBSA support now works correctly on amd64.
4505 * The NetIDMgr AFS Provider automated configuration logic was broken
4506 by the introduction of Kerberos referrals. If the realm of the
4507 identity cannot be determined, the workstation cell is now assumed
4508 to belong to the newly created identity.
4510 * Avoid a reference count under flow during rename operations.
4512 * Avoid a crash caused by treating an arbitrary length directory
4513 search mask as an 8.3 mask.
4515 * Prevent rename operations if a case insensitive match for the target
4516 name already exists and does not refer to the object being renamed.
4518 * Increase the maximum number of background daemons to 64.
4520 * Fix the UAC manifest applied to afs_config.exe

4816 on Rx connection objects used for volume location RPCs.
4818 * Over Quota errors during cm_FSync() calls would lead to an infinite
4819 loop as the error was never propagated to the caller.

4864 connection object while it is being selected. This avoids a race
4865 between threads attempting to set the timeout values and removes a
4866 bottleneck that was hampering performance.

5782 plugin for NetIDMgr will no longer use 100% of CPU.)
5784 * Renaming files on Microsoft Vista Build 5536 works.
5786 * Better handling of "." directory in fs commands
5788 * Add OpenAFS License text to installers
5790 * fs setquota and fs mkmount commands behave the same as the UNIX
5795 All systems: Major bugfixes.

5813 - fileserver needs to swap callback connections on a client IP change.
5815 - fileserver host package revised to reduce lock contention.
5817 - Rx has been fixed to count hard acks, thus opening the congestion window.
5819 - All servers support bound Rx sockets (on one interface).
5821 - namei fileserver no longer use lockf() to avoid range locking issues.
5823 - most binaries now support the -version switch.
5825 - backup suite fixes for 64 bit platforms.

5843 - audit logging fixes when stdarg does not provide integral va_list type.
5847 - A bug where the client kernel module could free stack memory (which
5848 caused issues with 64 bit Intel most commonly) has been fixed.
5850 - Packaging fixes and updates.
5852 - Uninstaller added.
5854 - Fix large file support.
5858 - autoconf kernel feature testing has been restructured.
5860 - PAG garbage collection is enabled by default.

5878 - Cleanup for loopback mount of AFS on Solaris 10.
5880 - Avoid issues with stdio not supporting file descriptors above 255 on
5881 Solaris 8 and lower in the fileserver.
5885 All systems: Major bugfixes.
5886 New systems: MacOS 10.4 (PowerPC and Intel)
5892 - Several race conditions in the host tracking and handling in the fileserver
5893 which could cause inconsistent behavior and crashes have been fixed.
5895 - A fileserver bug where a reference to a volume could be leaked and later
5896 cause a deadlock as a result of a bulk status call
5898 - Reference counting of fileserver objects in unsigned 32 bit integers
5899 instead of signed 16 bit integers.
5901 - Avoid type mismatches when handling time values (betweemn 32 bit and 64 bit
5904 - Fix a memory leak during multilevel packet queue handling.
5906 - Audit log output had been updated to include FIDs for newly created files.
5910 - 64 bit (large file) inodes are supported.
5912 - Salvager will now handle large (>4gb) partitions.
5918 - asetkey is now included to ease Kerberos 5 integration for server
5921 - A new fileserver statistics collection including callback statistics was
5924 - man pages are now generated.
5928 - Fixes error message problems experienced by fs.exe and the AFS Explorer
5929 Shell Extensions related to the use of Universal Error Codes by the
5932 - Adds full SMB/CIFS support for byte range locking. In this implementation
5933 all locks are allocated locally and the AFS lock privilege is ignored.
5934 While this will not prevent two processes on different machines from
5935 simultaneously writing to the same file, it will prevent two processes
5936 on the same machine from doing so.
5938 - The UP server check period has been reduced to once every ten minutes to
5939 match the period used by the UNIX clients. The shorter period will
5940 assist clients maintain RX connections through NATs.
5942 - Fixes the DOWN server check logic to ensure that any server that responds
5943 to a check is marked UP unless it is in the process of restarting.
5945 - Add logic to better handle objects that no longer exist on the file server.
5948 - Prevent the removal of existing drive mappings by "afscreds.exe -M"
5950 - Fixes the procmgmt library so that it doesn't cause applications that
5953 - Improves the warnings written to the afsd_init.log file when the
5954 Windows RPC Protocol drivers are improperly configured.
5956 - Fixes "fs setserverprefs -vlserver". Multiple calls with the same
5957 server parameter could result in a crash of afsd_service.exe.
5959 - The SMB/CIFS layer was audited for reference miscounts and memory leaks.
5960 All SMB objects are now properly counted, locked, and released when
5963 - Prevent file truncation of the user does not have the appropriate access.
5965 - Token management was re-written to allow user tokens to be preserved
5966 during integrated login and freed after logoff is complete.
5968 - Added a mechanism by which abandoned SMB virtual circuits can be
5969 detected and the associated resources cleaned up.
5971 - Prevent the allocation of SMB file handles with a value of 0 or 0xFFFF
5972 which would be considered invalid by Windows applications.
5974 - Fixed the processing of cell names to ensure that they are always
5975 treated as case insensitive strings.
5977 - Fixed the network provider code to avoid querying the profile location
5978 if integrated login is disabled.
5980 - If a mount point string is empty, return Path Not Found to the application.
5982 - Windows returns WSAECONNRESET when an ICMP packet is received in response
5983 to a transmitted UDP packet that cannot be delivered. Do not mark the
5984 connection as bad but instead retry the request.
5986 - Fix the data written to the registry as part of the BackConnectionHostnames
5989 - Fixed the rx-lwp implementation to always generate unique rx call
5992 - The default "fs minidump" type now includes data segments.
5997 * -nosettime is now the default for afsd. Use "-settime" to get the
6000 * OpenBSD is now supported.
6002 * Mountpoint directory information is now only faked for cross-cell
6003 mountpoints when using the -fakestat flag (e.g. for the directories
6004 under /afs, but not for most other volumes mounted inside the cell).
6005 The -fakestat-all switch can be used to fake information for all
6008 * When fakestat is enabled on MacOSX, the Finder can be used to browse
6009 a fully-populated /afs directory. However, this precludes reliable
6010 use of entire volumes as MacOS bundles (i.e. containing a Contents
6011 directory in the root of the volume).
6013 * Mountpoint directory information can be faked by the cache manager,
6014 making operations such as stat'ing all cells under /afs much faster.
6015 This is enabled by passing -fakestat to afsd, but might not be stable
6021 * The kaserver now defaults to not allowing interrealm authentication,
6022 due to security vulnerabilities in the krb4 protocol. The new
6023 "-crossrealm" flag to the kaserver is provided to reenable interrealm
6024 authentication if desired.
6026 * RedHat Linux 9.0 is now supported.
6028 * Solaris 9 12/02 is now supported. Solaris 7 and 8 x86 should now
6031 * On Linux machines using 2.2 series kernels, 2.2.19 or higher is now
6034 * An OpenAFS 1.2.9 afsd will not work with kernel modules built from
6035 an earlier OpenAFS release. In general, using a mismatched afsd and
6036 kernel modules set is unsupported; it is not recommended that you use
6037 such a configuration on a regular basis.
6042 * Mountpoint directory information is now only faked for cross-cell
6043 mountpoits when using the -fakestat flag (e.g. for the directories
6044 under /afs, but not for most other volumes mounted inside the cell).
6045 The -fakestat-all switch can be used to fake information for all
6048 * HPUX 11.0 is now supported.
6050 * It is now possible for AFS to use Kerberos 5 directly, via rxkad 2b.
6051 See the OpenAFS 1.2.8 Release Notes for more information on using this
6054 * An NFS translator kernel module is now included and compiled by
6055 default for Solaris only.
6060 * MacOS X 10.2 is now supported. FreeBSD 4.3 and later support is
6061 included in this release, but is still under active development and
6062 should only be used by those doing active development on the OpenAFS
6065 * When fakestat is enabled on MacOSX, the Finder can be used to browse a
6066 fully-populated /afs directory. However, this precludes reliable use
6067 of entire volumes as MacOS bundles (i.e. containing a Contents
6068 directory in the root of the volume).
6070 * The fileserver will now use Rx pings to determine if clients are
6071 reachable prior to allocating resources to them, to prevent asymmetric
6072 clients from consuming all fileserver resources.
6077 * Mountpoint directory information can be faked by the cache manager,
6078 making operations such as stat'ing all cells under /afs much faster.
6079 This is enabled by passing -fakestat to afsd.
6081 * Solaris 9 FCS and Solaris 7 and 8 x86 are now supported.
6086 * A remote denial of service attack in the AIX and IRIX clients has been
6087 fixed. Users of those platforms are strongly encouraged to upgrade.
6089 * Fixed race conditions in fileserver that could result in crash.
6094 * Server logfiles now more consistant about format in which hosts are
6097 * vfsck on Solaris will now allow force runs (using -y flag) even if old
6103 * Cell aliases for dynroot can be specified in the CellAlias file in
6104 /usr/vice/etc or /usr/local/etc/openafs, in format "realname alias",
6105 one per line. They can also be managed at runtime with "fs newalias"
6106 and "fs listaliases".
6111 * Solaris 9 and Linux PA-RISC are now supported.
6113 * fileserver will not erroneously delay legitimate errors for 3 seconds
6114 after 10 errors are returned (e.g. stat() on a directory you can't
6117 * Rx MTU calculation now works for Irix, Solaris and Linux
6119 * If afsd is started with the -dynroot flag, /afs will be locally
6120 generated from the CellServDB. AFSDB cells will be mounted
6121 automatically upon access.
6123 * The namei fileserver allows vice "partitions" to be directories
6124 instead of partitions and will attach and display accordingly.
6125 Creating the file "AlwaysAttach" in the /vicepX directory is used as
6126 the trigger to attach it.
6128 * TSM support for butc no longer requires editing a Makefile, simply
6129 specify the --enable-tivoli-tsm configure option.
6131 * Linux builds no longer require source changes every time the kernel
6132 inode structure changes; the OpenAFS sources will now configure itself
6133 to the actual inode structure as defined in the kernel sources.
6138 * vfsck on Digital UNIX and Solaris will now refuse to fsck mounted
6144 * AFS now supports --prefix and the other directory options of
6145 configure. By default AFS builds assuming it will be installed in
6146 /usr/local. In order to get traditional AFS directory paths (/usr/afs
6147 and /usr/vice/etc) use the --enable-transarc-paths option to
6148 configure. More details on the new directory layout are found in
6154 * Windows 95/98/ME/NT/2000 - Consistent versioning: Installation, AFS
6155 Control Center, Client dialog boxes and properties pages for
6156 executables display a consistent OpenAFS version number. Installation
6157 detects previous installation and prompts the user for upgrade
6160 * Windows 95/98/ME/NT/2000 - Installation features: During installation
6161 the user can select the source of the CellservDB file, AFS home cell,
6162 and drive mappings. During installation a drive path mapping can
6163 include a variable that will be substituted with the current UserName
6166 * Windows 2000/NT - Integrated logon: The Integrated Logon feature
6169 * Windows 95/98/ME - Logon script features: The Windows 95/98/ME client
6170 now offers a command-line option for starting up the AFS client
6171 without authenication. It is now possilbe to start the AFS client
6172 first and obtain tokens, and map drives all through Windows scripts.
6173 This helps using Windows 95/98/ME client in Kerberos 5 environment.
6175 * Windows 2000/NT - LANA numbers: AFS client now scans the LANA numbers
6176 to establish the correct NETBIOS connection. NetBEUI is no longer
6177 needed. The user no longer needs to find the correct LANA number.
6179 * Windows 2000/NT - OpenAFS naming consistancy: Further progress has
6180 been made to remove references to "Transarc AFS" and replace with
6186 * AFS now builds with configure. The README for building has been
6187 updated and includes full details.
6189 * A client system can now have multiple sysname values for @sys. They
6190 will be searched in order when looking up files in AFS. The
6191 -newsysname argument to fs sysname can be repeated to set multiple
6194 * A new system group is created for new cells (system:ptsviewers with id
6195 -203). If this group exists, members of this group can examine and
6196 read the entire protection database. They can examine all users and
6197 groups and can get the membership of any group.
6199 * A new program, pt_util has been added to the distribution. This
6200 program allows users to print the contents of the protection database
6201 or to edit the protection database without running a ptserver. It can
6202 be used to set up a new cell without ever running in noauth mode. Run
6203 pt_util -h for help.
6205 * The fs setcrypt and fs getcrypt commands have been added. These
6206 commands allow the system administrator to require that the client
6207 encrypt all authenticated traffic between the client workstation and
6208 AFS. The encryption used is weak, but is likely better than sending
6209 unencrypted traffic in most environments. Some functions, such as
6210 looking for a volume may not be encrypted, but data transfer certainly
6211 is. By default data is not encrypted. At this time no significant
6212 experimentation with server performance has been conducted.
6214 * By default AFS is compiled with AFS_AFSDB_ENV, enabling the -afsdb
6215 option to be given to afsd on startup. If this option is used, then
6216 new cells will be looked up using AFSDB records stored in DNS if they
6217 are not found in CellServDB. This means that users can create
6218 cross-cell mountpoints in directories they control to access cells not
6219 in root.afs, and that cells in root.afs need not be in the client's
6222 * AFS database servers can be marked as read-only clones. Surround the
6223 hostname in square brackets on the bos addhost command and the
6224 database server will never be elected sync site. This is useful for
6225 cells distributed over a wide region.
6227 * The AFS servers now support the -syslog flag. This flag causes them
6228 to log to syslog rather than to files. This flag is not supported on
6229 NT. For all servers besides the salvager, the flag can also be
6230 specified as -syslog=facility, where facility is an integer facility
6231 code from syslog.h. A -syslogfacility option is provided for the
6232 salvager to accomplish the same goal.
6234 * If the --enable-fast-restart flag is given when configuring AFS, then
6235 the salvager supports the -dontsalvage flag which causes it to exit
6236 without salvaging any volumes. If this is configured into the third
6237 command of a fs process, then the fileserver will start without
6238 salvaging. It will fail to attach volumes that need salvaging and
6239 they can be salvaged manually. This provides significantly better
6240 server startup performance at the cost of administrative complexity.
6242 * If the --enable-bitmap-later flag is given when configuring AFS, then
6243 the fileserver creates bitmaps for free vnodes on demand, allowing
6246 * If bosserver finds a BosConfig.new file at startup, it reads this file
6247 and renames it to BosConfig. This allows bosserver to be reconfigured
6250 * The bosserver can be placed in a restricted mode in which AFS
6251 superusers are only granted limited access to the server host. The
6252 following functionality is disabled when restricted mode is in use:
6255 bos getlog (except for files with no '/'s in their name)*
6261 specific exceptions are made for functionality that "bos salvage"
6264 A cron bnode who's name is "salvage-tmp", time is now, and command
6265 begins with "/usr/afs/bin/salvager" may be created. This bnode deletes
6266 itself when complete, so no special "delete" support is needed. This
6267 functionality may be removed in the future if a "Salvage" RPC is
6270 The file with the exact path /usr/afs/logs/SalvageLog may be fetched,
6271 since that is how bos salvage [...] -showlog is implimented.
6273 Restricted mode is enabled using a new bos command (bos setrestricted)
6274 or bossever command line switch (bosserver -restricted). Restricted
6275 mode can be disabled by a) sending the bosserver process a SIGFPE
6276 (which will then allow restricted operations until the next restart or
6277 setrestricted command) or b) editing /usr/afs/local/BosConfig (or
6278 BosConfig.new), and restarting the bosserver.
6280 * The bos UserList of trusted administrators can now contain cross-realm
6281 Kerberos principals.
6283 * udebug now takes --server not --servers.
6285 * Several error messages have been improved to include volume numbers.
6287 * Several new ports have been included for UNIX platforms: Darwin
6288 (ppc_darwin_12 and ppc_darwin_13), Linux 2.4 (i386_linux24), Linux on
6289 the Powerpc (ppc_linux22 and ppc_linux24), Linux on the Sparc
6290 (sparc_linux22, sparc64_linux22 and sparc64_linux24).
6292 * Incomplete FreeBSD and Alpha Linux ports are included. The FreeBSD
6293 port has a working server and the Alpha Linux port has a partially
6296 * A native client for Windows 95/98/ME has been added to the
6297 distribution. With this program, a gateway machine is no longer
6298 required for Windows 9x to access AFS files. One drive letter will be
6299 created on your machine by default - Z:. The Z: drive will be the
6300 root of the AFS tree, allowing you to browse all sites that have AFS
6301 servers available. Additional drive letters can be defined for other
6302 AFS directories. A Windows Explorer shell extension is included that
6303 allows you to right click on items within an AFS tree to bring up an
6304 "AFS" menu item and perform various operations on a file or directory.
6305 The most useful item is "Access Control Lists", which allows you to
6306 view and edit the permissions of a particular directory. Command line
6307 tools are also available in the install directory. These commands
6308 include klog, unlog, tokens, kpasswd, symlink, fs and pts. The
6309 installable includes a readme file that contains more information on
6310 how to use the client program and known issues.
6312 * Support for large caches in afsd. Cachefiles are stored in
6313 subdirectories. The default is 2048 files per subdirectory, which
6314 should work fine in most situations. You can use the new afsd option
6315 -files_per_subdir to change this number. Note that the first time you
6316 run afsd with this patch, your cachefiles will get moved into
6317 subdirectories. If you subsequently run an older version of afsd, you
6318 will lose all your cached files.
