      discrepency between the mask used for testing for readonly behavior
      and that used for setting the attribute.

    * 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.

    * Improve the error output from aklog to output the value from krb5
      error_message() if the afs_com_err output indicates an unknown

      only keyring-based PAGs, and disable group PAGs entirely.

    * Updates to the kernel page cache interface: writing pages will now
      not spuriously leak page locks, and will avoid requiring duplicate
      work.

    * Credential references are now tracked using native atomic counters.

    * Kernel mutex/semaphore lock ordering fix to avoid deadlocks.

    * Manipulate disk cache with credentials used to initialize it, to
      avoid security issues.

      fileservers to not come online immediately.

  Microsoft Windows

    * Official support for Windows 7 and Server 2008 R2.

    * Prevent a file server bug (FetchData returning an invalid length
      instead of zero) from causing an "unexpected network error" when
      writing to files.

    * Promote DNS SRV records as superior to DNS AFSDB records.  Support
      arbitrary port numbers for vldb servers.

    * 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.

    * Remove drive mapping functionality and service start/stop from
      afscreds.exe.

    * Remove drive mapping functionality from afs_config.exe.

    * Use {HKLM,HKCU}\SOFTWARE\OpenAFS\Client DWORD "ShowMountTab" to
      restore access to drive mapping functionality in afscreds.exe and
      afs_config.exe.

    * Adjust SMB error return codes to avoid returning STATUS_TIMEOUT
      which results in the SMB redirector disconnecting.

    * 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.

    * Prevent pioctl calls from retrying indefinitely when a sharing
      violation error occurs.

  All UNIX client platforms

    * Correct a condition which could discard the error from initializing
      a fetch request.

    * Avoid using invalid references to afs_Conn connection structures,
      and thus potentially producing invalid data when a retry is needed.

    * SRV records are now supported for discovering AFS servers.

  Linux

    * Correct writepage behavior.

    * Fix error code handling in the writepage code.

    * Avoid leaking page locks, which could potentially hang a machine.

  MacOS X

    * Preferences Pane improvements.

  HP-UX

    * Avoiding attempting to handle critical signals in servers, so that
      core file handling works correctly.


OpenAFS 1.5.65 (2009-10-06)

  All platforms

    * Code compilation warning fixes, to enable better finding and
      tracking bugs.

    * 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
      systems to save roaming profiles.

  All UNIX client platforms

    * A bug which could cause erroneous handling of lengths on data reads
      has been fixed.

    * A bug where erroneous length returns from the fileserver could
      result in a false error has been fixed.

  Linux

    * Background page copies are now supported for enhanced disk cache
      read performance.

    * Blocking readahead is supported in readpages() to reduce overhead.

    * Use readpage() instead of read() to access cache data to avail disk
      cache users of the kernel backing cache for improved performance.

    * Minimize credential handling for improved performance.

  MacOS X

    * Preferences Pane cleanup.

  Solaris

    * Provide a fs_pathconf method with sensible defaults.

  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
      by the integration tool included with the preferences pane.

    * Several packaging bugs have been corrected.

      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
      configure time by setting the CC environment variable.

    * afsd now properly deals with large cache partitions.

  FreeBSD

    * Build shared libafsauthent and libafsrpc.

  Linux

    * Kernel module DKMS support now installs an unstripped module to
      allow debugging information to be collected.

  MacOS

    * Preferences pane properly updates token information.

  MacOS 10.6

    * 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.

  NetBSD

    * Avoid defining AFS_KERBEROS_ENV globally as it creates a circular
      dependency.

    * Build shared libafsauthent and libafsrpc.

  OpenBSD

    * Build shared libafsauthent and libafsrpc.


OpenAFS 1.5.62 (2009-08-28)

  All platforms

    * 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
      implemented.

    * Unnecessary DNS lookups of share names are avoided improving
      performance.

  All UNIX client platforms

    * Non-Kerberos PAM modules work correctly again.

  MacOS X

    * MacOS 10.6 (Snowleopard) is now supported, both 32 and 64 bit mode.

    * Updates to the AFSCommander preferences pane.

    * Installer now permits cell names with dashes.


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 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.

  Solaris

    * Avoid kernel panics due to null pointer dereferences in the network
      interface poller kernel thread.


OpenAFS 1.5.60 (2009-05-31)

  All platforms

    * Retry volserver transaction creation on failure.

    * Allow building HTML and PDF documentation from included XML copies
      of User Guide, Admin Guide and Quick Start Guide for Unix.

    * Documentation updates and additional documentation.

    * Add -encrypt support to pts client.

    * Convert MR-AFS fs commands to OSD commands.

  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.

  DragonflyBSD

    * Support as a userland port.

  FreeBSD

    * Corrected structure definition for userspace cache manager to allow
      builds to complete.

  Linux

    * Corrected client locking support.

    * Updated patch to stop deadlocking in the kernel during mmap.

    * Avoid oops when setting up groups for PAGs to match keyrings.

    * Use Linux fh-based cache in cases where possible by default.

  MacOS 10.3:

    * Corrected structure definition for userspace cache manager to allow
      builds to complete.

  OpenBSD

    * Support for OpenBSD 4.5.

  Solaris

    * Corrected support for server-side vos split interface.


OpenAFS 1.5.59 (2009-04-06)

  Microsoft Windows

    * Increased service priority class to "High" to match the priority of
      system components that are dependent upon the a timely response.

    * SMB error responses avoid returning errors that could confuse the
      Microsoft SMB redirector into disconnecting the connection to \\AFS.

  All UNIX client platforms (except MacOS X 10.4 and 10.5)

    * OpenAFS 1.5.59 contains fixes for the client issues addressed by the
      security advisories OPENAFS-SA-2009-001 and OPENAFS-SA-2009-002.

  Linux platforms

    * Support for prerelease Linux 2.6.30 kernels.


OpenAFS 1.5.58 (2009-03-30)

  All platforms

    * Code cleanup and prototyping.

    * Avoid unnecessary blocking in Rx periodic cleanup code.

  All server platforms

    * Fileserver CopyOnWrite routine optimized for performance.

    * Make fileserver callback dumps 64 bit safe.

    * Fix byte order issues with fileserver host hashing.

    * Fix buffer size issues with butc.

    * Fix several Ubik recovery issues.

    * Avoid leaking file references in the fileserver.

    * Fix a race in DAFS while closing vnodes, and another offlining
      volumes.

    * 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.

    * Windows specific Rx performance improvements.

    * Support for Network Identity Manager 2.0

  All UNIX client platforms

    * Avoid issues with freeing resources at shutdown.

    * Numerous fixes to disconnected AFS.

    * Disconnected AFS fixes for replaying changes without double-freeing.

    * Attempt to use krb524 principal conversion in aklog if available.

  AIX

    * Kerberos configuration at build time corrected.

      examination with vos.

  Microsoft Windows

    * Undo the "UAC manifest fix" applied to afs_config.exe.

    * Ensure that Freelance allocation of vnodes follow the AFS convention
      of odd vnodes are directories and everything else is an even vnode.

    * Add Freelance logic to mount point and symlink evaluation functions.

    * Enhance smb_ParseASCIIBlock() so that it can handle all of the
      STRING formats defined by the CIFS Technical Report 1.0.

    * Validate the output of smb_ParseASCIIBlock() in all callers.  Return
      CM_ERROR_BADSMB if the STRING field cannot be parsed.
      CM_ERROR_BADSMB will cause the contents of the packet to be logged.

    * If multiple SMB Raw Write operations were taking place at the same
      time, there could be data corruption because unique event objects
      were not generated for each Netbios receive operation.

  All UNIX client platforms

    * Userspace AFS library can now deal with large files when supported

    * butc XBSA support now works correctly on amd64.

  Microsoft Windows

    * The NetIDMgr AFS Provider automated configuration logic was broken
      by the introduction of Kerberos referrals.  If the realm of the
      identity cannot be determined, the workstation cell is now assumed
      to belong to the newly created identity.

    * Avoid a reference count under flow during rename operations.

    * Avoid a crash caused by treating an arbitrary length directory
      search mask as an 8.3 mask.

    * Prevent rename operations if a case insensitive match for the target
      name already exists and does not refer to the object being renamed.

    * Increase the maximum number of background daemons to 64.

    * Fix the UAC manifest applied to afs_config.exe

  All server platforms

    * Demand Attach fileserver tries to avoid issues tracking offline
      status of volumes.

  Microsoft Windows

    * Many potential deadlock conditions due to out of order lock
      acquisitions have been corrected.

    * A race condition resulting in an undercount on the cm_scache_t
      reference counts has been corrected.

    * An empty string when sent as an ioctl path is now properly
      interpreted as meaning the current directory.  This affects "fs
      lsm", "symlink list", etc.

    * Fix smb string parsing differences where the smb protocol
      documentation does not match the actual Windows implementation.

    * Random access denied errors fixed.

    * A file server lock synchronization issue was corrected in SMB
      NTCreateX and NTTranCreate operations.  This bug prevented properly
      operation when loading roaming profiles.

      server.

    * Remove volume id from the server volume list in response to VMOVED
      and VNOVOL errors.

    * "fs flushXXX" commands now destroy locally built B+ directory trees.

    * Prevent mixture of locally modified directory pages and file server

      readonly volume or one that is marked with the readonly DOS
      attribute.

    * Fix a heap corruption error when reading the CellServDB file
      location.

    * Add the "RxUdpBufSize" registry value.  The new default is 256KB.

    * Do not include trailing NULs in the directory search output.
      (1.5.50)

    * Pre-allocate 64 Rx Packet buffers per thread in order to improve
      performance.

    * For debugging: add smb lock requests and stat cache lock allocations
      to the output from "fs memdump".

  NetBSD

    * Workaround broken sigwait() to allow fileserver to shut down
      correctly pre NetBSD 5.0.

  Solaris 10

    * Default to namei fileserver; Allow inode fileserver at configure
      time by override.

  NFS translator

    * Try harder to avoid kernel panics for malformed requests.


OpenAFS 1.5.51 (2008-07-29)

  All platforms

    * salvager tries harder to arrange for clients to get VBUSY while
      salvaging single volumes.

    * salvager avoids certain corruption when salvaging directories.

    * Rx connection clones disabled.

  Microsoft Windows

    * The 32-bit EXE 1.5.50 installer failed to properly install the C
      Runtime library.  When used as an upgrade OpenAFS would continue to
      work but when used as a new installation, OpenAFS binaries would
      fail to load.

    * Fixes the "fs" and "symlink" commands to properly parse Unicode path
      prefixes during the pioctl remote procedure call.  This bug would
      result in file not found errors for files and directories that
      clearly exist.  (Bug introduced in 1.5.50)

    * Large File support is disabled. (Bug introduced in 1.5.50)

    * Removes the possibility of a deadlock during volume location update
      operation if all of the reported file servers are unreachable at the
      time of the update.

    * Ensures that reference counts are properly incremented/decremented
      on Rx connection objects used for volume location RPCs.

    * Over Quota errors during cm_FSync() calls would lead to an infinite
      loop as the error was never propagated to the caller.

  All UNIX client platforms

    * Bugfixes to disconnected AFS support in the cache manager.


OpenAFS 1.5.50 (2008-07-16)

  All platforms

    * volserver puts recloned volumes back online before returning the
      volume to the fileserver, avoiding spurious VNOVOL errors.

    * Updated TSM X/Open API support available.

    * Demand Attach fileserver will not crash due to accesses during
      volume cloning.

    * Substantial documentation updates.

    * Demand Attach fileserver state tracking and analyzer tool
      improvements.

    * UAFS userspace cachemanager updates.

    * Corrected support for anti-meltdown protection in the client.

  Microsoft Windows

    * UNICODE Character Set Support.

    * Pioctl interfaces to the cache manager have been refactored to
      provide layering between the SMB specific code and the general
      purpose ioctl operation.

    * Garbage collect dead SMB virtual circuits as soon as they are no
      longer being referenced.  This avoids problems with outstanding
      locks not being dropped when the virtual circuit becomes invalid.

    * Remove the IBM Administration Reference documentation and replace it
      with the OpenAFS Command Reference Manual.

    * Avoid calling rx_SetDeadTime and rx_SetHardDeadTime functions each
      time a connection is about to be used.  Do not hold a lock on the rx
      connection object while it is being selected.  This avoids a race
      between threads attempting to set the timeout values and removes a
      bottleneck that was hampering performance.

    * Ensure that the smb directory attribute is set for all directory
      objects.

    * Replace the VC Runtime EXE installer with the MSI installer in the
      NSIS installer scripts.

  Solaris

    * Support for updates to OpenSolaris.

  Linux

    * Correct dentry revalidation for cross-directory renames.

    * Updated rpm packaging materials for 1.5 release series and 2.4
      kernels.

    * Corrected syscall table probing.

    * NFS translator updates for current kernels.


OpenAFS 1.5.39 (2008-06-24)

  All platforms

    * Updates for Demand Attach fileserver.

  Microsoft Windows

    * Fix two memory leaks.

    * Fix one missing lock.

    * Handle access denied errors when writing dirty buffers.

    * Fix two errors that would cause the *experimental* AFS Servers
      to crash.


OpenAFS 1.5.38 (2008-05-24)

  All platforms

    * Add read-only disconnected support.


OpenAFS 1.5.37 (2008-05-21)

  All platforms

    * Includes a number of optimizations for testing.


OpenAFS 1.5.36 (2008-05-09)

  All platforms

    * Rx optimizations now attempt to deal with high latency WANs.

    * 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.

    * vos move will not erroneously unlock locked vldb entries on failure.

  All server platforms

    * Fileserver avoids a potential infinite loop when a client
      relinquishes an address.

    * Fileserver large setting now configures more threads.

    * Fileserver properly registers uuids of new clients.

    * Ubik servers do not improperly hide updates from clients.

    * Fileservers reserve enough file descriptors such that each thread
      can cache one to avoid spurious errors.

  Microsoft Windows

    * Fix a cm_buf_t reference count leak when attempts to write dirty
      buffers to the file server from within cm_IncrSyncer() fail.

    * Prevent udebug from crashing.

    * 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.


=======> Changes back to 1.3 have not yet been incorporated here <=======


OpenAFS 1.3

  * -nosettime is now the default for afsd.  Use "-settime" to get the
    old behavior.

  * OpenBSD is now supported.

  * Mountpoint directory information is now only faked for cross-cell
    mountpoints when using the -fakestat flag (e.g. for the directories
    under /afs, but not for most other volumes mounted inside the cell).
    The -fakestat-all switch can be used to fake information for all
    mountpoints.

  * When fakestat is enabled on MacOSX, the Finder can be used to browse
    a fully-populated /afs directory.  However, this precludes reliable
    use of entire volumes as MacOS bundles (i.e. containing a Contents
    directory in the root of the volume).

  * Mountpoint directory information can be faked by the cache manager,
    making operations such as stat'ing all cells under /afs much faster.
    This is enabled by passing -fakestat to afsd, but might not be stable
    on all platforms.


OpenAFS 1.2.9

  * The kaserver now defaults to not allowing interrealm authentication,
    due to security vulnerabilities in the krb4 protocol.  The new
    "-crossrealm" flag to the kaserver is provided to reenable interrealm
    authentication if desired.

  * RedHat Linux 9.0 is now supported.

  * Solaris 9 12/02 is now supported.  Solaris 7 and 8 x86 should now
    work again.

  * On Linux machines using 2.2 series kernels, 2.2.19 or higher is now
    required.

  * An OpenAFS 1.2.9 afsd will not work with kernel modules built from
    an earlier OpenAFS release.  In general, using a mismatched afsd and
    kernel modules set is unsupported; it is not recommended that you use
    such a configuration on a regular basis.


OpenAFS 1.2.8

  * Mountpoint directory information is now only faked for cross-cell
    mountpoits when using the -fakestat flag (e.g. for the directories
    under /afs, but not for most other volumes mounted inside the cell).
    The -fakestat-all switch can be used to fake information for all
    mountpoints.

  * HPUX 11.0 is now supported.

  * It is now possible for AFS to use Kerberos 5 directly, via rxkad 2b.
    See the OpenAFS 1.2.8 Release Notes for more information on using this
    capability.

  * An NFS translator kernel module is now included and compiled by
    default for Solaris only.


OpenAFS 1.2.7

  * MacOS X 10.2 is now supported.  FreeBSD 4.3 and later support is
    included in this release, but is still under active development and
    should only be used by those doing active development on the OpenAFS
    FreeBSD client.

  * When fakestat is enabled on MacOSX, the Finder can be used to browse a
    fully-populated /afs directory.  However, this precludes reliable use
    of entire volumes as MacOS bundles (i.e. containing a Contents
    directory in the root of the volume).

  * The fileserver will now use Rx pings to determine if clients are
    reachable prior to allocating resources to them, to prevent asymmetric
    clients from consuming all fileserver resources.


OpenAFS 1.2.6

  * Mountpoint directory information can be faked by the cache manager,
    making operations such as stat'ing all cells under /afs much faster.
    This is enabled by passing -fakestat to afsd.

  * Solaris 9 FCS and Solaris 7 and 8 x86 are now supported.


OpenAFS 1.2.5

  * A remote denial of service attack in the AIX and IRIX clients has been
    fixed.  Users of those platforms are strongly encouraged to upgrade.

  * Fixed race conditions in fileserver that could result in crash.


OpenAFS 1.2.4

  * Server logfiles now more consistant about format in which hosts are
    referred to.

  * vfsck on Solaris will now allow force runs (using -y flag) even if old
    inodes exist.


OpenAFS 1.2.3

  * Cell aliases for dynroot can be specified in the CellAlias file in
    /usr/vice/etc or /usr/local/etc/openafs, in format "realname alias",
    one per line.  They can also be managed at runtime with "fs newalias"
    and "fs listaliases".


OpenAFS 1.2.2

  * Solaris 9 and Linux PA-RISC are now supported.

  * fileserver will not erroneously delay legitimate errors for 3 seconds
    after 10 errors are returned (e.g. stat() on a directory you can't
    read).

  * Rx MTU calculation now works for Irix, Solaris and Linux

  * If afsd is started with the -dynroot flag, /afs will be locally
    generated from the CellServDB.  AFSDB cells will be mounted
    automatically upon access.

  * The namei fileserver allows vice "partitions" to be directories
    instead of partitions and will attach and display accordingly.
    Creating the file "AlwaysAttach" in the /vicepX directory is used as
    the trigger to attach it.

  * TSM support for butc no longer requires editing a Makefile, simply
    specify the --enable-tivoli-tsm configure option.

  * Linux builds no longer require source changes every time the kernel
    inode structure changes; the OpenAFS sources will now configure itself
    to the actual inode structure as defined in the kernel sources.


OpenAFS 1.2.1

  * vfsck on Digital UNIX and Solaris will now refuse to fsck mounted
    mounted partitions.


OpenAFS 1.2.0

  * AFS now supports --prefix and the other directory options of
    configure.  By default AFS builds assuming it will be installed in
    /usr/local.  In order to get traditional AFS directory paths (/usr/afs
    and /usr/vice/etc) use the --enable-transarc-paths option to
    configure.  More details on the new directory layout are found in
    README.


OpenAFS 1.1.1a

  * Windows 95/98/ME/NT/2000 - Consistent versioning:  Installation, AFS
    Control Center, Client dialog boxes and properties pages for
    executables display a consistent OpenAFS version number.  Installation
    detects previous installation and prompts the user for upgrade
    options.

  * Windows 95/98/ME/NT/2000 - Installation features:  During installation
    the user can select the source of the CellservDB file, AFS home cell,
    and drive mappings.  During installation a drive path mapping can
    include a variable that will be substituted with the current UserName
    that is logged in.

  * Windows 2000/NT - Integrated logon:  The Integrated Logon feature
    works now.

  * Windows 95/98/ME - Logon script features:  The Windows 95/98/ME client
    now offers a command-line option for starting up the AFS client
    without authenication. It is now possilbe to start the AFS client
    first and obtain tokens, and map drives all through Windows scripts.
    This helps using Windows 95/98/ME client in Kerberos 5 environment.

  * Windows 2000/NT - LANA numbers:  AFS client now scans the LANA numbers
    to establish the correct NETBIOS connection.  NetBEUI is no longer
    needed.  The user no longer needs to find the correct LANA number.

  * Windows 2000/NT - OpenAFS naming consistancy:  Further progress has
    been made to remove references to "Transarc AFS" and replace with
    "OpenAFS".


OpenAFS 1.0

  * AFS now builds with configure. The README for building has been
    updated and includes full details.

  * A client system can now have multiple sysname values for @sys.  They
    will be searched in order when looking up files in AFS.  The
    -newsysname argument to fs sysname can be repeated to set multiple
    sysnames.

  * A new system group is created for new cells (system:ptsviewers with id
    -203).  If this group exists, members of this group can examine and
    read the entire protection database.  They can examine all users and
    groups and can get the membership of any group.

  * A new program, pt_util has been added to the distribution.  This
    program allows users to print the contents of the protection database
    or to edit the protection database without running a ptserver.  It can
    be used to set up a new cell without ever running in noauth mode.  Run
    pt_util -h for help.

  * The fs setcrypt and fs getcrypt commands have been added.  These
    commands allow the system administrator to require that the client
    encrypt all authenticated traffic between the client workstation and
    AFS.  The encryption used is weak, but is likely better than sending
    unencrypted traffic in most environments.  Some functions, such as
    looking for a volume may not be encrypted, but data transfer certainly
    is.  By default data is not encrypted.  At this time no significant
    experimentation with server performance has been conducted.

  * By default AFS is compiled with AFS_AFSDB_ENV, enabling the -afsdb
    option to be given to afsd on startup.  If this option is used, then
    new cells will be looked up using AFSDB records stored in DNS if they
    are not found in CellServDB.  This means that users can create
    cross-cell mountpoints in directories they control to access cells not
    in root.afs, and that cells in root.afs need not be in the client's
    CellServDB.

  * AFS database servers can be marked as read-only clones.  Surround the
    hostname in square brackets on the bos addhost command and the
    database server will never be elected sync site.  This is useful for
    cells distributed over a wide region.

  * The AFS servers now support the -syslog flag.  This flag causes them
    to log to syslog rather than to files.  This flag is not supported on
    NT.  For all servers besides the salvager, the flag can also be
    specified as -syslog=facility, where facility is an integer facility
    code from syslog.h.  A -syslogfacility option is provided for the
    salvager to accomplish the same goal.

  * If the --enable-fast-restart flag is given when configuring AFS, then
    the salvager supports the -dontsalvage flag which causes it to exit
    without salvaging any volumes.  If this is configured into the third
    command of a fs process, then the fileserver will start without
    salvaging.  It will fail to attach volumes that need salvaging and
    they can be salvaged manually.  This provides significantly better
    server startup performance at the cost of administrative complexity.

  * If the --enable-bitmap-later flag is given when configuring AFS, then
    the fileserver creates bitmaps for free vnodes on demand, allowing
    faster starts.

  * If bosserver finds a BosConfig.new file at startup, it reads this file
    and renames it to BosConfig.  This allows bosserver to be reconfigured
    at next restart.

  * The bosserver can be placed in a restricted mode in which AFS
    superusers are only granted limited access to the server host. The
    following functionality is disabled when restricted mode is in use:

      bos exec
      bos getlog (except for files with no '/'s in their name)*
      bos create *
      bos delete
      bos install
      bos uninstall

    specific exceptions are made for functionality that "bos salvage"
    uses:

    A cron bnode who's name is "salvage-tmp", time is now, and command
    begins with "/usr/afs/bin/salvager" may be created. This bnode deletes
    itself when complete, so no special "delete" support is needed.  This
    functionality may be removed in the future if a "Salvage" RPC is
    implimented.

    The file with the exact path /usr/afs/logs/SalvageLog may be fetched,
    since that is how bos salvage [...] -showlog is implimented.

    Restricted mode is enabled using a new bos command (bos setrestricted)
    or bossever command line switch (bosserver -restricted). Restricted
    mode can be disabled by a) sending the bosserver process a SIGFPE
    (which will then allow restricted operations until the next restart or
    setrestricted command) or b) editing /usr/afs/local/BosConfig (or
    BosConfig.new), and restarting the bosserver.

  * The bos UserList of trusted administrators can now contain cross-realm
    Kerberos principals.

  * udebug now takes --server not --servers.

  * Several error messages have been improved to include volume numbers.

  * Several new ports have been included for UNIX platforms: Darwin
    (ppc_darwin_12 and ppc_darwin_13), Linux 2.4 (i386_linux24), Linux on
    the Powerpc (ppc_linux22 and ppc_linux24), Linux on the Sparc
    (sparc_linux22, sparc64_linux22 and sparc64_linux24).

  * Incomplete FreeBSD and Alpha Linux ports are included.  The FreeBSD
    port has a working server and the Alpha Linux port has a partially
    working client.

  * A native client for Windows 95/98/ME has been added to the
    distribution.  With this program, a gateway machine is no longer
    required for Windows 9x to access AFS files.  One drive letter will be
    created on your machine by default - Z:.  The Z: drive will be the
    root of the AFS tree, allowing you to browse all sites that have AFS
    servers available.  Additional drive letters can be defined for other
    AFS directories.  A Windows Explorer shell extension is included that
    allows you to right click on items within an AFS tree to bring up an
    "AFS" menu item and perform various operations on a file or directory.
    The most useful item is "Access Control Lists", which allows you to
    view and edit the permissions of a particular directory.  Command line
    tools are also available in the install directory.  These commands
    include klog, unlog, tokens, kpasswd, symlink, fs and pts.  The
    installable includes a readme file that contains more information on
    how to use the client program and known issues.

  * Support for large caches in afsd.  Cachefiles are stored in
    subdirectories.  The default is 2048 files per subdirectory, which
    should work fine in most situations.  You can use the new afsd option
    -files_per_subdir to change this number.  Note that the first time you
    run afsd with this patch, your cachefiles will get moved into
    subdirectories.  If you subsequently run an older version of afsd, you
    will lose all your cached files.
