- All server platforms
+ All Server Platforms
- * RXAFS_GetStatistics64 now returns statistics properly.
+ * Ubik servers using pthreads are now available and are used by default
- Microsoft Windows
+ * As part of improving Ubik reliability in certain edge cases, an extra
+ election cycle (about 60 seconds) may be needed before writes are
+ permitted. This is a conservative change that may be removed in
+ the future.
- * Attempt to properly identify the local system SMB connection for
- token tracking.
+ * Remove periodic background fsync by the fileserver (ihandle fsync thread).
- * Remap timeout and offline errors to proper NT RPC errors.
+ * Fix potential file handle leak in the file server ihandle caching layer.
- * Properly fail over to other replicas on bulkstat IO errors.
+ * Disable the so-called "hot threads" feature in the file server. The hot
+ threads feature was intended as an optimization for dispatching incoming
+ calls to the current listener thread, but has been reported to incur a
+ performance penalty on modern multi-core systems.
- * Properly error delete-mode createfile if a file is set readonly.
+ * Do not permit creation of users with id of ANONYMOUSID.
- * Validate directory entry buffers to avoid crashing the service.
+ * Do not save/restore host states in the fsstate.dat file for hosts which

+ with IBM AFS log handling on server startup. Log messages may be lost
+ in back-to- back restarts when a server is running in this mode.
- All UNIX client platforms
+ * Reopen server logs on SIGUSR1. This may be used by third-party log
+ rotation tools, such as logrotate, to reopen the log file handles after
+ log files have been renamed.
- * cacheout program for discarding callbacks is now built.
+ * Fix various bugs when logging with -mrafslogs enabled.
- * bulkstatus kernel locking is corrected to avoid a potential panic.
+ * Dynamically reload the kerberos realm to AFS cell mapping (krb.conf) and
+ exclusions for mapping kerberos principals to AFS identities (krb.excl)
+ configuration when the CellServDB cell configuration file is touched.
+ Previously, a restart of the file server was required after updating the
+ kerberos mapping configuration files.
- Dragonfly BSD
+ * Add a command line option (-restricted_query) to the vlserver and
+ volserver to restrict information queries about volumes to a specific
+ group of users.
- * userspace support update
+ * Add a command line option to the server programs to specify an alternate
+ fully qualified log file name (-logfile).
- FreeBSD
+ * Add a command line option (-config) to the server programs to specify
+ an alternate path to the server configuration.
- * Updated vnode locking for children returned via lookup().
+ * Add a command line option to the ptserver and vlserver to specify an
+ alternate path to the database data files.

+ volume-server-to-volume-server-traffic (-s2scrypt).
- * Use vnode_pager_setsize to properly track file size during kernel
- IO.
+ * Increase the maximum number of LWP threads allowed for the ptserver and
+ vlserver from 16 to 64 (-lwp).

+ * Remove an unused file server command line option (-k).
- * Fix shutdown of Rx kernel listener to avoid potential dereference
- after it's gone.
+ * Fix an incorrect assertion in Demand Attach File Server which could cause

+ removed MR-AFS functionality..
+ * Remove calls to the deprecated sbrk() function.
-OpenAFS 1.5.76 (2010-08-16)
+ * Add an experimental feature to database servers to support ubik reads
+ while write transactions are in progress, enabled at build time with the
+ --enable-ubik-read-while-write configure option. This feature is not
+ considered ready for production usage at this time.
- All platforms
+ * Avoid filling the FileLog with "Volume x offline: not in service" when
+ a volume is administratively taken offline with vos offline.
- * Updates to build-time configuration.
+ * Print an error message when bosserver is started with an unknown
+ command line option.
- * Fix XDR support in Rx to match header definition.
+ * Modify the volume updateDate when the volume is changed by a salvage.
- * vos status now shows transaction creation, not action creation.
+ * Volume usage statistics are now preserved during reclone and restore

+ can be retained via the -clear-vol-stats argument.
- * Rx avoids reporting loopback adapters when listing interfaces.
+ All Client Platforms
- All server platforms
+ * Add support for relative ACL changes with fs setacl. If a single plus (+)

+ Due to changes to internal data structures with this kernel release,

+ instead of normal directories in order to satisfy Linux kernel
+ invariants, looking up paths containing more than 40 mount points
+ will fail with ELOOP on such kernels.

- * Keyring destruction now cleans up all tokens.
+ All server platforms
- * Keyring quotas are not enforced against root.
+ * Prior to the OpenAFS security release 1.6.13, the Volume Location
+ Server (vlserver) RPC VL_ListAttributesN2() supported wildcard volume
+ name lookups via regular expression (regex) pattern matching. This
+ support was completely disabled in 1.6.13 because it was judged to be
+ a security risk due to buffer overruns in the implementation, as well
+ as the possibility of denial of service attacks where certain regular
+ expressions could cause excessive CPU usage in some regex
+ implementations.
+
+ Unfortunately, after 1.6.13 was released, it was discovered that
+ the native OpenAFS 'backup' system uses the VL_ListAttributesN2()
+ regex support to evaluate configured volume sets. If you use the
+ OpenAFS 'backup' system (or another backup system which relies on it,
+ such as Tivoli Storage Manager (TSM, aka Tivoli ADSM)), and are using
+ volume sets which require regular expressions for the volume name,
+ then those volume sets cannot be resolved by OpenAFS 1.6.13. The next
+ paragraph provides details on how to identify any affected volume sets.
+
+ OpenAFS backup volume sets may be described by fileserver, partition
+ name, and volume name. The fileserver and partition specifications
+ never require regular expression support. The volume name specification
+ always requires regular expression support except for when specifying
+ _all_ volumes via two special cases: the universal wildcard ".*", or "".
+ For example, volume name "proj" or "*.backup" or "homevol.*" all
+ require regex support - even if the specification contains no wildcard
+ characters and/or exactly matches an existing volume name.
+
+ As a result of this issue, OpenAFS 1.6.14 replaces the 1.6.13 changes
+ to VL_ListAttributesN2. 1.6.14 prevents the buffer overruns and
+ reenables the regex support, but restricts it to OpenAFS super-users
+ and -localauth only. This is sufficient to restore the OpenAFS 'backup'
+ system's ability to work correctly with any previously supported volume
+ set. The OpenAFS 'backup' commands are already documented to require
+ super-user authorization, so this restriction is moot for the backup
+ system.
+
+ There are no other direct consumers of the VL_ListAttributesN2() regex
+ support in the OpenAFS tree. However, the VL_ListAttributesN2 RPC is
+ publicly accessible and might be used by third party tools directly or
+ indirectly via OpenAFS's libadmin. Any such tools that issue
+ VL_ListAttributesN2 RPCs must now be executed using super-user or
+ -localauth tokens.
+
+ None of the other security fixes in OpenAFS 1.6.13 are known to have
+ any issues, and are still included unchanged in OpenAFS 1.6.14.
+
+ If there are any questions concerning the possible impact of OpenAFS
+ 1.6.13 or 1.6.14 at your site, please contact your OpenAFS support
+ provider or the openafs-info@openafs.org mailing list for further
+ assistance.

+ trying to take offline. (6266 10799)
- * Update for current FreeBSD 8.
+ All client platforms
- Solaris
+ * When a client is shut down, it will give up its callbacks. The Windows

+ behaviour. (RT #131505) (9499)
- * Set the DOS Readonly attribute on a file/directory whenever the unix

- discrepency between the mask used for testing for readonly behavior
- and that used for setting the attribute.
+ * Restored the pre-1.6 behaviour when running vos examine for a volume
+ currently in a transaction, showing the volume as busy again rather than
+ offline. (9685 9915 9916)
- * Disable AFSVolSync based .readonly "whole-volume callback" support
- because the all file servers prior to 1.5.67 (and perhaps 1.4.12) do
- not properly assign a value to the AFSVolSync structure in bulk
- status RPC responses.
+ * Reduced the minimum time a bos salvage takes from 5 seconds to 1. (9476)
- * Improve the error output from aklog to output the value from krb5

+ in rare cases when a fileserver registered its addresses in the VLDB.
+ (9429)
- * Add dynamic server ranking based on RPC round trip time
- measurements.
+ * Added the -preserve-vol-stats switch to volserver, allowing it to keep

+ restart a server process. (9571 10199)
- * Additional shutdown-time memory leaks removed.
+ * Improved vldb_check (not installed by default) to cope with broken
+ vlentry names and volids, and provide more output to aid debugging.
+ (10268)
- * Improved logging of resource contention.
+ * Releasing a volume after adding a new RO site no longer touches any of
+ the existing RO sites, if the RW data hasn't changed since the last
+ release. (10174)
- * Provide dumping for Rx debug packet tracking support in source.
+ * Make the copyDate field for RO clones have the same meaning as for

+ * Fixed potentially undefined behaviour in ptserver when too many pts
+ ids are allocated. (10124)
- * Client buffers for directory parsing can now be allocated beyond the
- fixed set formerly provided.
+ * Note that the server side NAT pings feature present in the prereleases
+ was removed before the final release, since no positive feedback
+ was provided during prerelease testing. (9420 10135)
- * Work around race condition when manipulating read-only volume
- callbacks.
+ Linux servers
- * Bugfixes to get PAG value pioctl.

+ to track its state (10093)
- * Bugfixes to SRV record support.
+ All client platforms
- Linux
+ * No longer track file locks on read-only volumes. Write locks can't
+ succeed, read locks always will. Avoids log messages about this kind
+ of lock. (8910)
- * Path MTU tracking code cleanup.
+ * Added the "fs flushall" subcommand, which makes the client discard all
+ cached data. This was previously available on Windows only. (9065 9388
+ 9389 9390)
- * Avoid an oops due to racing with vcache recycling thread.
+ * Fixed a bug that could make the client incorrectly believe its cache
+ is up to date. This change could negatively impact AFS <-> DFS
+ translators, should those still be running anywhere. (8898)
- * Changes to keyring PAG handling: for sufficiently new kernels, use
- only keyring-based PAGs, and disable group PAGs entirely.
+ * Several changes to avoid panicing in certain error conditions.
+ (9131 9287 10354 10355 10356 10357) (partially addressing RT #131747)
- * Updates to the kernel page cache interface: writing pages will now
- not spuriously leak page locks, and will avoid requiring duplicate
- work.
+ * Added the -rxmaxfrags switch to afsd, allowing to limit the number
+ of UDP fragments sent or received per RX packet. (9430)
- * Credential references are now tracked using native atomic counters.
+ * Build fixes for aklog on several platforms (RT #131716) (9917 10107 10275)
- * Kernel mutex/semaphore lock ordering fix to avoid deadlocks.
+ * Require that the AFS mountpoint specified in the cacheinfo file is

- MacOS
+ Linux clients
- * Fix fstrace message catalog location.
+ * Support Linux kernels up to 3.13 (10241)
- * Fix kernel fstrace logging.
+ * Fixed a bug that made readv/writev calls in AFS space fail with Linux
+ kernels where generic_file_aio_read exists but those operations have
+ not been switched to using aio_read/aio_write. This was a regression
+ introduced with release 1.6.3 and affected at least RHEL 5.9 kernels.
+ (10248)
+ * Fixed a similar bug making core dumps fail in AFS space, affecting
+ a much wider range of kernels including the most recent ones.
+ (RT #131729) (10254)
-OpenAFS 1.5.66 (2009-10-25)
+ * Enhanced the keyring code to make PAGs work correctly on kernels with a
+ distribution specific change to the Linux keyring code. This affected at
+ least SLES 11 SP3 kernels. (10252)
- All platforms
+ * Fixed a bug that could make failures during PAG instantiation go
+ unnoticed. (10255)
- * Avoid calling exit() in library code.
+ * Fixed a bug that made compilation fail for Linux kernels without

+ OEM version of SLES 11 SP1. (10325)
- * Add rx window size and peer timeout tuning APIs.
+ * Fixed build for kernels with user namespace support enabled. Likely
+ to be required for Ubuntu 14.04 and eventually other distributions.
+ (10456 10457 10458 10518 10472)
- * Correct rx peer timeout handling to disallow 0ms timeouts.
+ * Support RHEL 6.5 kernels, and possibly others with changes backported
+ from recent mainline kernels that touch getname/putname, by no longer
+ using those functions. Previously, the client could cause a kernel
+ panic when syscall auditing was enabled. (10578)
- * Correct calculation of rx RTT by disregarding retransmitted packets.
+ * Make tmpfs usable as the cache filesystem again. This had been broken
+ since kernel 3.1 (9950 10193)
- * vos manpages updated to reflect changes in recent versions.
+ * When starting the client fails, clean up the backing device information
+ created in sysfs, to avoid error messages during a subsequent start
+ and possible system instability later on (10454)
- * GNU-style long options (e.g. --cell) are now supported in all
- commands.
+ * Update Red Hat packaging to support Fedora >= 20, RHEL >= 7 and
+ ELrepo kernels (10597 10619 10622 10703 10704)
- * fs listacl can now print a command to recreate the current ACL.

- * Fix a race on transaction objects in the volserver which can cause a
- crash.
+ AIX clients
- * Avoid destroying and setting to NULL the callback connection when it
- could still be being used.
+ * Fixed a bug that caused the 1.6 AIX client to never receive any RX
+ packets in the kernel. (RT #131725)
- * Correct unlink handling in salvager.
+ FUSE client
- * Improve error messages due to I/O errors in the volserver.
+ * Support Solaris 11 (9454 9455)

+ * Allow other users to access filesystems mounted by root. (9452)
- Microsoft Windows
+ FreeBSD
- * Official support for Windows 7 and Server 2008 R2.
+ * Build tvolser and dvolser on this platform (10122)
+ * Several fixes to catch up with newer releases (10374 .. 10381)
- * Prevent a file server bug (FetchData returning an invalid length
- instead of zero) from causing an "unexpected network error" when
- writing to files.
+ NetBSD

+ * Fixed build on NetBSD 5 and newer. (10138)
- * Add AFSVolSync based .readonly "whole-volume callback" support.
- With this functionality, multiple objects from a .readonly volume
- can have their status validated by issuing a single
- RXAFS_FetchStatus RPC.
+OpenAFS 1.6.5
- * Remove drive mapping functionality and service start/stop from
- afscreds.exe.
+All platforms
- * Remove drive mapping functionality from afs_config.exe.
+ * Fixes for OpenAFS-SA-2013-0003 and OpenAFS-SA-2013-0004
- * Use {HKLM,HKCU}\SOFTWARE\OpenAFS\Client DWORD "ShowMountTab" to
- restore access to drive mapping functionality in afscreds.exe and
- afs_config.exe.
+OpenAFS 1.6.4
- * Adjust SMB error return codes to avoid returning STATUS_TIMEOUT
- which results in the SMB redirector disconnecting.
+All platforms
- * Network Identity Manager OpenAFS Provider now provides its own "AFS
- lock" notification icon to report the status of "have tokens, have
- no tokens, service not started, service started but inaccessible".
- Hovering over the icon lists the cells for which tokens exist (if
- any) and the OpenAFS version number. Double-clicking executes the
- Network Identity Manager default action.
+ * Obey the jumbo/nojumbo settings for ubik servers (the DB servers)
+ too. In previous releases, those servers may have used jumbograms
+ even if they were not configured to do so. This change corrects
+ the actual behaviour, and will improve performance and reliability
+ for sites where jumbograms are problematic. It could cause a decrease
+ in performance for sites where jumbograms work, but those can turn
+ them back on manually.
- * Prevent pioctl calls from retrying indefinitely when a sharing
- violation error occurs.
+ * Dozens of fixes for common coding problems like use after free,
+ use of possibly uninitialised memory, reading or writing past the
+ end of arrays and potential NULL pointer derefences. Spotted by
+ code analysis tools or human inspection.
- All UNIX client platforms
+ * Documentation improvements.
- * Correct a condition which could discard the error from initializing
- a fetch request.
+ * Fixes and improvements to the diagnostic or log messages printed by
+ vos, the fileserver and others.
- * Avoid using invalid references to afs_Conn connection structures,
- and thus potentially producing invalid data when a retry is needed.
+ * Build fixes, making parallel builds more reliable with certain
+ configuration options and helping various platforms including
+ recent releases of IRIX, Solaris and several flavours of Linux.
- * SRV records are now supported for discovering AFS servers.
+ * Avoid sending a small amount of data over the wire unencrypted
+ under certain conditions, and emit the correct error message in
+ this case.
- Linux
+All server platforms
- * Correct writepage behavior.
+ * Avoid generating duplicate IDs for readonly and backup volumes,
+ which could happen under certain conditions.
- * Fix error code handling in the writepage code.
+ * Allow the fileserver to return volume data like quota or free space,
+ which is available publicly elsewhere, without the additional access
+ check for read permissions on a volume's root directory the fileserver
+ performed before.
- * Avoid leaking page locks, which could potentially hang a machine.
+ * The fileserver now emits a log message when it ran out of memory for
+ callbacks.
- MacOS X
+ * Avoid several potential fileserver problems, including memory
+ corruption and segmentation faults, due to client bookkeeping.
- * Preferences Pane improvements.
+ * Avoid known cases of silent data corruption due to background syncs
+ on the fileserver, especially during Copy on Write.
- HP-UX
+ * Make the fileserver sync behaviour runtime configurable. Up to 1.4.5,
+ we had synchronous syncs which were safe but really slow. Since 1.4.5,
+ we've had asynchronous syncs which are much faster but believed to
+ be the cause of rare data corruption issues, and while all known cases
+ of these happening are believed to be fixed in the 1.6.3 release, doubts
+ remain. This change allows choosing between those, and in addition allows
+ to turn syncs by the fileserver off altogether, thus relying on the vice
+ partition's backend filesystem and the operating system, or to just
+ execute them when a volume is detached. The default behaviour is
+ unchanged from releases since 1.4.5, but it's highly recommended to
+ consider the additional options this change provides. Future OpenAFS
+ releases will default to "-sync=none".
- * Avoiding attempting to handle critical signals in servers, so that
- core file handling works correctly.
+ * For dbservers, avoid a situation where misinterpreting transient
+ network errors causes long-term issues with achieving ubik quorum.
+All UNIX client platforms
-OpenAFS 1.5.65 (2009-10-06)
+ * Improvements to the detection of an aklog-specific krb5 configuration
+ file, for the purposes of turning on "weak crypto" for aklog.
+

+ supposedly persistent disk cache to be discarded upon client start.
+ (RT #131655)
+
+Linux clients
+
+ * Support Linux kernels up to 3.10
+
+ * Fixed two bugs making it impossible to unmount a disk cache filesystem
+ after it has been used by the client. (RT #131613)
+
+ * Fixed a bug that could cause an oops with kernels 3.6 and later
+
+OpenBSD
+
+ * Improved support for OpenBSD 4.9 to 5.3

+ * Documentation updates.
All server platforms
- * bosserver now handles BosConfig.new when restarting, allowing
- configuration to be replaced at restart time rather than with bos
- delete and bos create. Documentation is updated to reflect this.
+ * A file descriptor leak which could result in corrupted files in the
+ fileserver was fixed. An IMMEDIATE upgrade from previous 1.5 release
+ fileservers is recommended.
- * The demand attach fileservice not longer potentially hangs trying to
- terminate demand-salvages which have already exited.

- also experienced inconsistent behavior. This is fixed.
+ * Many changes to again support Windows fileservers.
- * CRITICAL: Multiple AFS pioctl requests issued nearly simultaneously
- by applications could result in pioctl responses being received by
- the wrong requester. This in turn could result in application
- crashes. symlink.exe, fs.exe, afslogon.dll, afscreds.exe, and the
- netidmgr afscred.dll plugin were all affected.

+ * In salvager check-only mode, avoid potentially fixing a vnode.
- * Ensure that access denied and over quota errors experienced while
- storing data to the file server do not result in on-going retry
- attempts.
+ * Fix support for large (greater than 2gb) volume special files.
- All UNIX client platforms
+ * Salvager will not crash if multiple or bad volume link tables are
+ encountered.

+ volume bitmap errors.
- * Preferences pane properly updates token information.
+ * Properly support large volume numbers (larger than 2147483647).
- MacOS 10.6
+ * Allow salvager to be run manually again when DAFS is being
+ used. (129458)
- * klog will now properly handle passwords of 8 or fewer characters
- with an AFS string to key on hosts able to run 64 bit binaries.
+ * Avoid leaking references to hosts during callback break multi-Rx
+ operations. (129376)

+ * Do not use RankServerInterval registry value as the value for
+ PerformanceTuningInterval.
-OpenAFS 1.5.62 (2009-08-28)
+ * When the data version of a mountpoint or symlink changes, the target
+ string in the cm_scache_t object must be cleared.
- All platforms
+ * "fs checkservers" now includes vldb servers in the output and only
+ lists multi-homed servers once. A multi-homed server that has at
+ least one up interface is no longer considered to be down.
- * Numerous invisible changes to improve code maintainability,
- portability and enhanceability.
+ * When asynchronously storing dirty data buffers to the file server
+ ensure that (a) the cm_scache_t object and the cm_buf_t object are
+ for the same File ID so that locking and signalling work properly;
+ and (b) if the FID no longer exists on the file server, do not
+ panic, just discard the buffer.
- Microsoft Windows
+ * When processing VNOVOL, VMOVED and VOFFLINE errors perform server
+ comparisons by UUID or address and not simply by cm_server_t
+ pointer. Otherwise, server failover may not succeed.
- * CRITICAL: Fixes two errors that can result in data loss when storing
- data to the file server.
- 1. Failure to Store Portions of Unaligned Writes
- 2. Failure to Store Data to File Servers Lacking Large File Support
- Read the announcement for more details:
- http://www.openafs.org/pipermail/openafs-announce/2009/000305.html
+ * Do not preserve status information for cm_scache_t objects when the
+ issuing server is multi-homed.
- * CRITICAL: The cache manager daemon thread could terminate when the
- machine enters suspend mode. This daemon thread performs the
- background check of down servers, offline volumes, callback
- expirations, etc.
+ * Giving up all callbacks when shutting down or suspending the machine
+ is now significantly faster due to the use of an rx_multi
+ implementation. (This functionality is still off by default and
+ must be activated by a registry value.)
- * CRITICAL: Integrated Logon (afslogon.dll) was terminating
- unexpectedly. Error checking has been improved and NULL pointer
- dereferences after Lsa API calls fail have been eliminated.
+ * Race conditions were possible when updating the state of the
+ cm_volume_t flags and when moving the volumes within the least
+ recently used list.
- * For the first time, the OpenAFS SMB Server supports the DCE RPC
- services SRVSVC and WKSSVC. Browsing \\AFS with the Explorer Shell
- or NET VIEW will now be faster and provide additional functionality.
- No longer will cell names longer than 12 characters be truncated.
+ * Ensure that the lanahelper library does not perform a NCBRESET of
+ each lan adapter when enumerating the current network bindings.
+ Correcting this permits OpenAFS to work on Windows 7 when the
+ network adapter settings change.
- * Improvements to DFS Referral request processing have been
- implemented.
+ * Fix creation of mount points and symlinks as \\AFS\xxxx
- * Unnecessary DNS lookups of share names are avoided improving
- performance.
+ * Icon tray state now conditionally set. (128591)
- All UNIX client platforms
+ * Properly create new cell mount points in freelance mode.
- * Non-Kerberos PAM modules work correctly again.
+ * Avoid recursive offline volume checks.
- MacOS X
+ * Fix caching of non-existent volumes. The test to trigger an
+ immediate CM_ERROR_NOSUCHVOLUME in cm_UpdateVolumeLocation() was
+ backwards.
- * MacOS 10.6 (Snowleopard) is now supported, both 32 and 64 bit mode.
+ * Prevent the background daemon from checking the status of
+ non-existent volumes. cm_CheckOfflineVolumes() should skip volume
+ groups with the CM_VOLUMEFLAG_NOEXIST flag set.
- * Updates to the AFSCommander preferences pane.
+ * The afskfw library should return an error immediately if the
+ krb5_32.dll library cannot be loaded. Affects afslogon.dll and
+ afscreds.exe.
- * Installer now permits cell names with dashes.
+ * No longer depend on leashw32.dll in afskfw library.
+ * NPLogonNotify must provide the user password in all calls to
+ KFW_AFS_get_cred(). It cannot count on a credential cache being
+ preserved between calls. Permits tokens to be acquired for all
+ cells listed in the TheseCells registry value for a domain.
-OpenAFS 1.5.61 (2009-08-06)
+ * Improve the trace logging from NPLogonNotify().
- All platforms
+ * Avoid a race when writing the cm_scache_t mountPointString
+ when acquiring mount point or symlink target data via
+ cm_GetData(). The race could result in bogus target
+ data being cached.
- * Correct another race condition in the Rx library that could result
- in an unexpected panic while freeing the Rx call iovq.
+ * Permit the use of des-cbc-md5 and des-cbc-md4 enctypes
+ as DES keys in asetkey.exe.
- * rx packet resend and data packets sent counts were incorrect.
+ * aklog supports dotted Kerberos v5 principal names.
- * fs setquota, fs setcachesize, vos setfields, and vos create now
- accept human readable orders of magnitude. (K, M, G)
+ * afskfw library always attempts afs/cell@USER-REALM
- * fs listquota fixed to permit large quota sizes to be displayed.
+ * afskfw library must test return code from krb5_cc_start_seq_get() or
+ will trigger a null pointer exception when using Heimdal.
- * Correct documentation of bosserver permissions requirements.
+ * Lock protected fields must be 32-bit in order to avoid memory
+ overwrite races.
- * Modify vlserver to avoid potentially corrupting the database through
- volume id reuse.
+ * Add support for NTFS symlinks.
- * Generalized support for fast Rx timeout due to network
- down/unreachable.
+ * Handle file search requests for virtual syscall ioctl file.
- All server platforms
+ * Process SyncOps properly to enforce ordered operations.
- * Allow audit logs to be sent via sys5 IPC message queues instead of
- logged directly.
+ * Avoid recursing during NewServer operations.
- Microsoft Windows
+ * Correct lock acquisition order during SMB locking.
- * If a file server becomes inaccessible while the cache manager has
- dirty buffers to write, the afsd_service buf_IncrSync thread can
- attempt to use 100% of the cpu.
+ * Add shutdown message to event log.
- * Fix "fs newcell" which was broken in 1.5.60.
+ * Check offline volume status by policy rather than on each daemon
+ thread run.
- * Do not attempt to synchronize dirty buffers if the associated volume
- is known to be unavailable.
+ * Return error on directory object not found instead of crashing.
- * Modify behavior of a Freelance mountpoint target that does not
- specify a cell. Instead of assuming the target volume is in the
- Freelance.Local cell, use the workstation "Cell" specified in the
- registry. A mountpoint target of "#root.cell." will now mean the
- root.cell volume in the workstation cell for the current session.
- If the workstation cell changes from "athena.mit.edu" to
- "andrew.cmu.edu", the referenced volume will also change without
- requiring that the mount point targets be altered.
+ * Improve error message output.
- * Add cm_FindServerByUuid(). Re-implement RXAFS_InitCallBackState3()
+ * afslogin.dll can start afsd_service if it's not starting or started.
+
+ * Optimize away release lock RPCs for deleted files.
+
+ * Background Daemon will not perform operations on deleted files.
+
+ * Resort recently used directories to the top of the LRU if the
+ directory is larger than the stat cache.
+
+ * Resort deleted objects to the bottom of the LRU.
+
+ * Use interlocked operations for state and queue fields to allow safe
+ bit set and clear on multiprocessor systems.
+
+ All UNIX client platforms
+
+ * Servers now marked down when GetCapabilities returns error.
+

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

+
+ Microsoft Windows
+
+ * Improved service response to suspend and shutdown event
+ notifications.
+
+ * Avoid a bug in the file server that can result in an invalid length
+ being returned as part of a fetch data response if the client
+ attempts to read beyond the length of the file.
+
+ * Do not publish a default stream object for directories and mount
+ point objects. This was impacting the ability of some Windows XP

+OpenAFS 1.5.64 (2009-09-22)
+
+ All server platforms
+
+ * The demand attach fileserver now puts back volume references gotten
+ via the fssync interface.
+
+ * The demand attach fileserver had a structure reference error, which
+ has been correected.
+
+ Microsoft Windows
+
+ * Restores Windows 2000 compatibility.
+
+ * Fixes a data consistency error between the output of NetWkstaGetInfo
+ and NetServerGetInfo RPCs, specify the Lan workstation group name
+ "AFS", and report server name as "AFS" instead of "\\AFS" when the
+ caller asks for "\\AFS".
+
+ * Enables executables to be run from \\AFS on Windows 7. Returns
+ "Name not found" instead of "File not found" when a directory or
+ file name cannot be found. This avoids loader errors when system
+ dlls cannot be located in the executable directory.
+
+ * Prevents cache manager from marking the file server "down" when the
+ data returned in response to either RXAFS_FetchData64 or
+ RXAFS_StoreData64 is invalid.
+
+ * Adds pioctl data validation to the AFS Explorer Shell extension.
+
+ All UNIX client platforms
+
+ * A bug which could cause a kernel panic in 1.5.63 has been corrected.
+ This would manifest as a GetDCache panic or oops.
+
+ Linux
+
+ * aklog -setpag works again with recent kernels when keyring is in
+ use.
+
+ MacOS
+
+ * When Fast User Switch is in use, AFS login is now handled correctly

+
+ * Several packaging bugs have been corrected.
+
+
+OpenAFS 1.5.63 (2009-09-11)
+
+ All platforms
+
+ * The restorevol command is now documented and installed as a user
+ command.
+
+ * The uss command now properly translates vldb entries to its expected
+ format when handling them in all cases.
+
+ * Documentation now refers to Kerberos instead of kaserver.
+
+ All server platforms
+
+ * bosserver now handles BosConfig.new when restarting, allowing
+ configuration to be replaced at restart time rather than with bos
+ delete and bos create. Documentation is updated to reflect this.
+
+ * The demand attach fileservice not longer potentially hangs trying to
+ terminate demand-salvages which have already exited.
+
+ * The demand attach fileservice has been modified to avoid spurious
+ 'SYNC_putRes: write failed' warnings when some protocol messages
+ cannot be acknowledged due to the sender terminating the connection.
+
+ * In the event of failure to contact the vlserver or ptserver, the
+ fileserver will not exit and trigger a forced salvage. It will
+ continue to try in the background to contact the needed services.
+
+ * The salvager can now repair certain cases of a damamged vnode index.
+
+ * The accessDate metadata for a volume is now updated correctly.
+
+ Microsoft Windows
+
+ * CRITICAL: Some applications for example those based on Cygwin were
+ unable to access data stored in the AFS name space. Explorer Shell
+ also experienced inconsistent behavior. This is fixed.
+
+ * CRITICAL: Multiple AFS pioctl requests issued nearly simultaneously
+ by applications could result in pioctl responses being received by
+ the wrong requester. This in turn could result in application
+ crashes. symlink.exe, fs.exe, afslogon.dll, afscreds.exe, and the
+ netidmgr afscred.dll plugin were all affected.
+
+ * Some XP machines running 1.5.62 had trouble saving roaming profile
+ data. This is fixed.
+
+ * Integrated Logon (afslogon.dll) did not function with domain
+ specific configurations.
+
+ * Ensure that access denied and over quota errors experienced while
+ storing data to the file server do not result in on-going retry
+ attempts.
+
+ All UNIX client platforms
+
+ * Except on Solaris and AIX, the compiler may now be overriden at

+
+ * klog will now properly handle passwords of 8 or fewer characters
+ with an AFS string to key on hosts able to run 64 bit binaries.
+
+ * A panic at AFS shutdown due to "NO PCB" on a udp_lock has been
+ addressed.
+
+ * The panic decoder script included in the source now properly handles
+ 32 and 64 bit panics.

+
+ * Numerous invisible changes to improve code maintainability,
+ portability and enhanceability.
+
+ Microsoft Windows
+
+ * CRITICAL: Fixes two errors that can result in data loss when storing
+ data to the file server.
+ 1. Failure to Store Portions of Unaligned Writes
+ 2. Failure to Store Data to File Servers Lacking Large File Support
+ Read the announcement for more details:
+ http://www.openafs.org/pipermail/openafs-announce/2009/000305.html
+
+ * CRITICAL: The cache manager daemon thread could terminate when the
+ machine enters suspend mode. This daemon thread performs the
+ background check of down servers, offline volumes, callback
+ expirations, etc.
+
+ * CRITICAL: Integrated Logon (afslogon.dll) was terminating
+ unexpectedly. Error checking has been improved and NULL pointer
+ dereferences after Lsa API calls fail have been eliminated.
+
+ * For the first time, the OpenAFS SMB Server supports the DCE RPC
+ services SRVSVC and WKSSVC. Browsing \\AFS with the Explorer Shell
+ or NET VIEW will now be faster and provide additional functionality.
+ No longer will cell names longer than 12 characters be truncated.
+
+ * Improvements to DFS Referral request processing have been

+OpenAFS 1.5.61 (2009-08-06)
+
+ All platforms
+
+ * Correct another race condition in the Rx library that could result
+ in an unexpected panic while freeing the Rx call iovq.
+
+ * rx packet resend and data packets sent counts were incorrect.
+
+ * fs setquota, fs setcachesize, vos setfields, and vos create now
+ accept human readable orders of magnitude. (K, M, G)
+
+ * fs listquota fixed to permit large quota sizes to be displayed.
+
+ * Correct documentation of bosserver permissions requirements.
+
+ * Modify vlserver to avoid potentially corrupting the database through
+ volume id reuse.
+
+ * Generalized support for fast Rx timeout due to network
+ down/unreachable.
+
+ All server platforms
+
+ * Allow audit logs to be sent via sys5 IPC message queues instead of
+ logged directly.
+
+ Microsoft Windows
+
+ * If a file server becomes inaccessible while the cache manager has
+ dirty buffers to write, the afsd_service buf_IncrSync thread can
+ attempt to use 100% of the cpu.
+
+ * Fix "fs newcell" which was broken in 1.5.60.
+
+ * Do not attempt to synchronize dirty buffers if the associated volume
+ is known to be unavailable.
+
+ * Modify behavior of a Freelance mountpoint target that does not
+ specify a cell. Instead of assuming the target volume is in the
+ Freelance.Local cell, use the workstation "Cell" specified in the
+ registry. A mountpoint target of "#root.cell." will now mean the
+ root.cell volume in the workstation cell for the current session.
+ If the workstation cell changes from "athena.mit.edu" to
+ "andrew.cmu.edu", the referenced volume will also change without
+ requiring that the mount point targets be altered.
+
+ * Add cm_FindServerByUuid(). Re-implement RXAFS_InitCallBackState3()
to permit the server Uuid to be used to lookup the server object and
from that determine the cell. This permits callbacks that are
received from alternate addresses to be processed with a known
server object. Previously a request from an unknown server would
clear all callbacks from all cells.
- * Fix a bug that prevented optimal performance when using a non-zero
- value for 'daemonCheckVolCBInterval'. As a reminder, when
- "daemonCheckVolCBInterval" is set to a non-zero value, all .readonly
- volume callbacks are automatically renewed 90 minutes before their
- expiration.
+ * Fix a bug that prevented optimal performance when using a non-zero
+ value for 'daemonCheckVolCBInterval'. As a reminder, when
+ "daemonCheckVolCBInterval" is set to a non-zero value, all .readonly
+ volume callbacks are automatically renewed 90 minutes before their
+ expiration.
+
+ * Fix automatic ranking of vldb servers whose values are obtained from
+ the CellServDB file.
+
+ * Add failover for RX CALL TIMEOUT errors when the volume is readonly
+ or the call is to a vldb server.
+
+ * Add registry based cell search functionality to NetIdMgr,
+ afs_config.exe, and klog.exe.
+
+ * afsconf_GetCellInfo() has been modified to perform gethostbyname()
+ lookups on the host names in the CellServDB instead of using the
+ specified IP addresses. This provides aklog, pts, vos, etc. the
+ same CellServDB behavior that the Windows Cache Manager uses.
+
+ * When updating the stat cache entry callback of a .readonly object
+ from the volume group object, update the file server reference to
+ ensure it matches the most update to date callback.
+
+ * Add proper support for processing callbacks from multi-homed file
+ servers. Instead of comparing servers by cm_server_t pointer,
+ compare them by UUID when the UUID is known.
+
+ * During a shutdown short circuit the offline volume check daemon
+ functionality.
+
+ * Return the error code of RXAFS_FetchData / RXAFS_StoreData in
+ preference to an error code reported by rx_EndCall.
+
+ * Add "PerFileAccessCheck" registry value to permit testing against
+ experimental file servers that include per-file acl support. This
+ value is intentionally undocumented. It is not to be used by
+ production environment deployments.
+
+ * Fix a bug introduced in 1.5.60 that prevents the afs netidmgr
+ provider from obtaining tokens when referrals are in play.
+
+ * Add "fs chown" and "fs chgrp" commands to permit the owner and group
+ of objects stored in AFS to be set from Windows.
+
+ * Avoid performing background daemon operations when the machine is
+ going into suspend mode.
+
+ * Perform offline volume checks in most recently used order.
+
+ * Prevent crash when a data version for a cache object goes backwards.
+
+ * Multi-thread safe library versions are now being generated and used.
+ mtafsubik.lib, mtafsutil.lib, mtafsvldb.lib, mtafsvol.lib.
+
+ * Microsoft SMB Redirector (mrxsmb.sys) support for
+ ExtendedSessTimeout values are now available on XP through Windows
+ 7. Add functionality to autodetect if such support is present on
+ the machine. If so, configure it if necessary and dynamically
+ adjust the AFS Rx timeout values accordingly.
+
+ All UNIX client platforms
+
+ * Fix out-of-tree source builds.
+
+ MacOS
+
+ * GUI installer now asks for local cell information.
+
+ * AFS Commander preferences pane is now installed by default.

+
+ * Avoid kernel panics due to null pointer dereferences in the network

+
+ All server platforms
+
+ * Updated background sync process in fileserver to avoid a race which
+ could result in a volume being taken offline.
+
+ Microsoft Windows
+
+ * On April 9th Microsoft released a Hot Fix for Windows Server 2003
+ SP2 that corrects a deadlock in the smb redirector and also adds new
+ functionality that permits the AFS SMB server to be given a longer
+ timeout than is normally the case. New functionality has been added
+ to configure these additional LanmanWorkstation\Parameter values.
+ (This functionality has been backported to XP SP3 and is scheduled
+ to be released on June 5th.)
+
+ * Fix RT#124787, a race condition between "fs flush <dir>", "fs
+ flushvolume", or "fs flushall" and on-going directory operations
+ that can result in afsd_service.exe crashing.
+
+ * Release Notes, User and Administrator guides are now shipped as
+ indexed Windows HtmlHelp Files. (.chm). Shortcuts are provided from
+ the Start Menu.
+
+ * A method of specifying Client CellServDB information within the
+ registry has been added that can be used to either override the
+ CellServDB file or force the use of DNS lookups for a given cell.
+ See the release notes for details.
+
+ * The pioctl interface now properly handles drive letter substitution
+ to UNC paths. (SUBST <d:> <\\afs\cell\path>)
+
+ * The BackConnectionHostNames registry value configuration was broken
+ when dynamic re-establishment of Netbios Name registrations was
+ added. This release restores the functionality.
+
+ * All hidden vos.exe commands are now revealed.
+
+ * Attempts to store the same dirty file chunk from multiple threads
+ are now prevented.
+
+ * The IsPathInAfs test in Explorer Shell Extension and fs.exe now
+ permits broken symlinks to be treated as being in AFS.
+
+ * vos.exe commands that output 64-bit integer values once again do so.
+ This was broken in 1.5.59.
+
+ * Cygwin Import Libraries are provided in the SDK for all OpenAFS
+ DLLs. This permits building cygwin applications against OpenAFS
+ libraries.
+
+ * NSIS installer does a much better job of cleaning up files left over
+ from previous installs.
+
+ * libafsconf.dll moved from Client\Program to Common directory as is
+ is now used by all modules for CellServDB processing.
+
+ All UNIX client platforms
+
+ * Write back changes on last store for memcache to avoid discarding
+ changes.
+
+ * Abstract disk cache support to allow for path, fh, inode based
+ caches with no need for messy ifdef structures each time a new type
+ is added.
+

+ * volserver interfaces for volume splitting client.
+
+ Microsoft Windows
+
+ * [RT 124293] A race condition exists which can result in a crash.
+
+ * [RT 124276] If the vldb is out of sync with the contents of the file
+ servers, afsd_service will retry too many times when a file server
+ reports a volume as not being present. Now if the list reported by
+ the vldb is the same as the previously seen list, then the retry is
+ aborted.
+
+ * [RT 124276] Read-only volume failover was broken in 1.5.53 whenever
+ accessing a volume results in VNOVOL or VMOVED.
+
+ * [RT 124276] Prior to 1.3.70 the volume server reference list was not
+ reference counted and would be prematurely freed while in use. When
+ reference counting was added in 1.3.70 a bug was introduced that
+ could result in service reference list corruption.
+
+ * Add Windows Application Event Log warning messages for "Client SMB
+ MPX value too large" and "Client SMB Buffer Size too small".
+
+ * Renaming of files across directory boundaries would result in an
+ invalid handle error when attempting to access the files after the
+ move.
+
+ * Fix the handling of Tran2 Set Path Info RPCs. Do not fail when a
+ smb file descriptor cannot be found. The whole point of using a
+ Path Info function is because an smb file descriptor wasn't
+ allocated.
+
+ * More edge cases in which dynamic addition of Freelance root.afs
+ entries would get the wrong FID or where the root.afs directory
+ would not be refreshed.
+
+ * Buffer overflow could occur if the workstation cell name was longer
+ than 64 characters. Crashes could occur in afscreds.exe,
+ afslogon.dll, and afsd_service.exe.
+
+ * VNOSERVICE and VOFFLINE errors were leaking and were exposed to the
+ smb client.
+
+ * Log file server uuid values as part of the cm_server object when
+ available. Dump the cm_server object list in response to "fs
+ memdump".
+
+ * Optimize the performance of resetting access control lists when
+ tokens are set or removed.
+
+ * Remove symlink recursion tests and increase max symlink count to 64
+ from 16.

- * Corrected syscall table probing.
+ All systems:
- * NFS translator updates for current kernels.
+ - Several race conditions in the host tracking and handling in the fileserver
+ which could cause inconsistent behavior and crashes have been fixed.
+ - A fileserver bug where a reference to a volume could be leaked and later
+ cause a deadlock as a result of a bulk status call
-OpenAFS 1.5.39 (2008-06-24)
+ - Reference counting of fileserver objects in unsigned 32 bit integers
+ instead of signed 16 bit integers.
- All platforms
+ - Avoid type mismatches when handling time values (betweemn 32 bit and 64 bit
+ variables).
- * Updates for Demand Attach fileserver.
+ - Fix a memory leak during multilevel packet queue handling.
- Microsoft Windows
+ - Audit log output had been updated to include FIDs for newly created files.
- * Fix two memory leaks.
+ HP-UX 11i:
- * Fix one missing lock.
+ - 64 bit (large file) inodes are supported.
- * Handle access denied errors when writing dirty buffers.
+ - Salvager will now handle large (>4gb) partitions.
- * Fix two errors that would cause the *experimental* AFS Servers
- to crash.
+ * New features:
+ All systems:
-OpenAFS 1.5.38 (2008-05-24)
+ - asetkey is now included to ease Kerberos 5 integration for server
+ administrators.
- All platforms
+ - A new fileserver statistics collection including callback statistics was
+ added.
- * Add read-only disconnected support.
+ - man pages are now generated.
+ Microsoft Windows:
-OpenAFS 1.5.37 (2008-05-21)
+ - Fixes error message problems experienced by fs.exe and the AFS Explorer
+ Shell Extensions related to the use of Universal Error Codes by the
+ AFS File Server
- All platforms
+ - Adds full SMB/CIFS support for byte range locking. In this implementation
+ all locks are allocated locally and the AFS lock privilege is ignored.
+ While this will not prevent two processes on different machines from
+ simultaneously writing to the same file, it will prevent two processes
+ on the same machine from doing so.
- * Includes a number of optimizations for testing.
+ - The UP server check period has been reduced to once every ten minutes to
+ match the period used by the UNIX clients. The shorter period will
+ assist clients maintain RX connections through NATs.
+ - Fixes the DOWN server check logic to ensure that any server that responds
+ to a check is marked UP unless it is in the process of restarting.
-OpenAFS 1.5.36 (2008-05-09)
+ - Add logic to better handle objects that no longer exist on the file server.
+ (VNOVNODE errors.)
- All platforms
+ - Prevent the removal of existing drive mappings by "afscreds.exe -M"
- * Rx optimizations now attempt to deal with high latency WANs.
+ - Fixes the procmgmt library so that it doesn't cause applications that
+ unload it to crash.
- * Client will not wait infinitely for a server which is not providing
- data. Additional servers will be polled without marking the server
- which is not providing data down.
+ - Improves the warnings written to the afsd_init.log file when the
+ Windows RPC Protocol drivers are improperly configured.
- * vos move will not erroneously unlock locked vldb entries on failure.
+ - Fixes "fs setserverprefs -vlserver". Multiple calls with the same
+ server parameter could result in a crash of afsd_service.exe.
- All server platforms
+ - The SMB/CIFS layer was audited for reference miscounts and memory leaks.
+ All SMB objects are now properly counted, locked, and released when
+ their work is done.
- * Fileserver avoids a potential infinite loop when a client
- relinquishes an address.
+ - Prevent file truncation of the user does not have the appropriate access.
- * Fileserver large setting now configures more threads.
+ - Token management was re-written to allow user tokens to be preserved
+ during integrated login and freed after logoff is complete.
- * Fileserver properly registers uuids of new clients.
+ - Added a mechanism by which abandoned SMB virtual circuits can be
+ detected and the associated resources cleaned up.
- * Ubik servers do not improperly hide updates from clients.
+ - Prevent the allocation of SMB file handles with a value of 0 or 0xFFFF
+ which would be considered invalid by Windows applications.
- * Fileservers reserve enough file descriptors such that each thread
- can cache one to avoid spurious errors.
+ - Fixed the processing of cell names to ensure that they are always
+ treated as case insensitive strings.
- Microsoft Windows
+ - Fixed the network provider code to avoid querying the profile location
+ if integrated login is disabled.
- * Fix a cm_buf_t reference count leak when attempts to write dirty
- buffers to the file server from within cm_IncrSyncer() fail.
+ - If a mount point string is empty, return Path Not Found to the application.
- * Prevent udebug from crashing.
+ - Windows returns WSAECONNRESET when an ICMP packet is received in response
+ to a transmitted UDP packet that cannot be delivered. Do not mark the
+ connection as bad but instead retry the request.
- * Another VNOVNODE issue fixed. When writing a dirty buffer to the
- file server, if VNOVNODE is received, mark all buffers as invalid
- without further attempts to contact the file server.
+ - Fix the data written to the registry as part of the BackConnectionHostnames
+ values.
+ - Fixed the rx-lwp implementation to always generate unique rx call
+ identitiers.
-=======> Changes back to 1.3 have not yet been incorporated here <=======
+ - The default "fs minidump" type now includes data segments.
