+Since 1.5.9904 (1.6pre4)
+ * Fix caching of non-existent volumes. The test to
+ trigger an immediate CM_ERROR_NOSUCHVOLUME in
+ cm_UpdateVolumeLocation() was backwards.
+
+ * 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.
+
+ * The afskfw library should return an error immediately
+ if the krb5_32.dll library cannot be loaded. Affects
+ afslogon.dll and afscreds.exe.
+
+ * 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.
+
+ * Improve the trace logging from NPLogonNotify().
+
+ * 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.
+
+ * Permit the use of des-cbc-md5 and des-cbc-md4 enctypes
+ as DES keys in asetkey.exe.
+
+Since 1.5.9903 (1.6pre3)
+ * Fix automatic addition of Freelance cell mount points
+ broken in 1.5.9902.
+
+ * Avoid recursive offline volume checks which could cause
+ a crash due to stack exhaustion.
+
+Since 1.5.9902 (1.6pre2)
+ * rx calls issued on a busy call channel are now specially
+ handled and logged. All calls are automatically retried.
+
+ * The vos support for multi-homed servers was incorrectly
+ implemented. The changes have been reverted.
+
+ * Avoid wasting cm_buf_t objects and associated data buffers
+ for obtaining mountpoint and symlink target strings. Instead
+ read them directly into the cm_scache_t mountPointTarget
+ buffer.
+
+ * Optimize the evaluation of mountpoint and symlink targets
+ by skipping the FetchStatus and a full round-trip if
+ the cache manager does not have valid status information
+ for the object.
+
+ * Fix the abstraction of cm_FreelanceAddMount() by passing
+ in volume names that do not include the trailing dot.
+
+Since 1.5.78
+ [there was no 1.6pre1 for Windows]
+
+ * vos commands now manipulate servers by UUID and can
+ recognize multi-homed servers.
+
+ * afs_config will not longer set the Tray Icon State
+ in the registry if the checkbox is not present in
+ the dialog. [RT 128591]
+
+ * Heimdal's roken utility library has been added
+ as \Program Files\Common\afsroken.dll
+
+ * When probing servers to determine if they are up or down
+ no longer issue an RXAFS_GetTime RPC to servers that indicated
+ that they do not understand the RXAFS_GetCapabilities RPC.
+ Since they responded it is known that they are up.
+
+ * AFS Explorer Shell Extension now works from folder
+ backgrounds. Overlays for mount points and symlinks
+ are present in the dll, but are not registered at present
+ by the installers.
+
+ * Do not use RankServerInterval registry value as the value for
+ PerformanceTuningInterval.
+
+ * CellServDB updated to 13 Dec 2010 release from grand.central.org
+
+ * Add "fs chmod" command and display current mode as part
+ of "fs examine" output.
+
+ * When the data version of a mountpoint or symlink changes,
+ the target string in the cm_scache_t object must be cleared.
+ Otherwise, the new target will not be queried.
+
+ * "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.
+
+ * 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.
+
+ * 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.
+
+ * Do not preserve status information for cm_scache_t objects
+ when the issuing server is multi-homed.
+
+ * 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.)
+
+ * 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.
+
+ * 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.
+
+ * Fix creation of mount points and symlinks as \\AFS\xxxx
+
+
+Since 1.5.77
+ * Reimplement FetchData and StoreData operations to make
+ use of rx_Writev and rx_Readv which is faster than than
+ multiple calls to rx_Write and rx_Read. Throughput
+ improvements of up to 20% are possible.
+
+ * Many improvements to the rx rpc stack:
+
+ - RTT measurements
+
+ - Fast recovery is not triggered by packet resend timeouts
+
+ - Socket errors are now detected and reported
+
+ - avoid repetitive memory allocations
+
+ - avoid calling gettimeofday() for every packet
+
+ - reduced dependency on the call->lock
+
+ - When a call receive is completed, ack all of the packets
+ immediately. Do not wait for the first response packet
+ to be sent.
+
+ - Do not hold the call->lock during rx_Write* and rx_Read*
+ operations when the call fields in use can only be accessed
+ by the application thread.
+
+ - Reduce the default window size from 128 back to 32 because
+ the current overhead from walking packet queues in the rx
+ listener thread significantly hampers the ability to
+ process incoming packets from the network.
+
+ - Only backoff the peer timeout once for a series of naks.
+
+ - Release builds are lean and mean. All debugging and
+ packet tracking code is disabled.
+
+ * Version number is logged to the Windows Application Event
+ Log as part of the start pending message.
+
+ * MSI installers now backup and restore configuration
+ data during upgrades.
+
+ * Rx pmtu discovery has been disabled by default. Use
+ HKLM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
+ RxPMTUDiscovery "DWORD"
+ value to re-activate.
+
+ * cm_BkgDaemon event evaluation has been optimized to avoid
+ unnecessary overhead.
+
+ * If a volume is known to be readonly, then locally fail any
+ change request without sending it to the file server. This
+ avoids triggering the file server's abort threshold.
+
+ * Do not leak cm_volume_t objects from the volume LRU queue.
+
+ * Ensure that cm_NameI errors are acted upon promptly.
+ There are many cases in the SMB server where an error from cm_NameI()
+ was either ignored or not acted upon until several other operations
+ are performed that could result in the same error being repeated.
+ This is a mistake which did not have negative side effects until
+ additional checks for callback status were added recently.
+
+ At present, if a CM_ERROR_ACCESS error is returned and ignored,
+ subsequent attempts to operate on the same cm_scache_t will result
+ in additional queries to the file server that will also end in an
+ abort response. This can trigger the file server to delay responses
+ to the client.
+
+ * Fix fs mount point and symlink create operations which were
+ failing due to improper directory separator termination.
+
+ * RXAFS_GetVolumeStatus can return VNOVOL, VMOVED, etc. In
+ order to process them and update volume state a fid must
+ be passed to cm_Analyze(). Use the volume root fid.
+
+ * Negative caching for volume lookups that fail with either
+ VL_NOENT or VL_BADNAME. The expiration time is five minutes.
+ This prevents volume lookup storms.
+
+ * Provide each volume lookup its own two hour lifetime instead
+ of reseting all volume location information every two hours.
+ This prevents the first smb path evaluation after the volume
+ location data has been discarded from potentially causing an
+ smb client timeout.
+
+Since 1.5.76
+ * When the SYSTEM account is in use, the SMB connection is
+ not always established as S-1-5-18. Sometimes it uses an
+ anonymous, S-1-5-7, connection. In both cases the SMB
+ authentication name is the nul string. To better identify
+ when an SMB connection is local system, the smb_username_t
+ is now stored as a SID instead of a user name. When a SID
+ is used, a new flag bit is set SMB_USERNAMEFLAG_SID.
+
+ In smb_SetToken if AFS_PIOCTL_AFSLOGON is set and the user
+ connection is not SYSTEM, the RPC SID is checked. If RPC
+ SID is SYSTEM, that supercedes the SMB authentication.
+
+ * Replace STATUS_IO_TIMEOUT with RPC_NT_SERVER_TOO_BUSY for
+ CM_ERROR_ALLBUSY.
+
+ * Replace STATUS_PATH_NOT_FOUND with RPC_NT_SERVER_UNAVAILABLE
+ for CM_ERROR_ALLOFFLINE and CM_ERROR_ALLBUSY.
+
+ * Optimize behavior of buf_CleanAsyncLocked(). Avoid searching
+ for the cm_scache_t object by FID if it is already known.
+
+ * If the readonly file attribute is set (stored as a unix mode)
+ then a CreateFile operation should fail if the file is opened
+ for DELETE in combination with any other privilege.
+
+ * If the directory buffer contents are garbage we can crash
+ the service. Add some simple validation checks to ensure
+ that cm_dirEntry_t objects have the correct flag value and
+ that the name strings are not too long.
+
+ * If the bulkStat errorCode indicates that a particular object
+ is inaccessible due to a VIO error, we must update the server
+ status appropriately in order to permit failover.
+
+ * An RX_MSGSIZE error is returned by the new PMTU detection
+ code. It is critical that such an error result in a retry of
+ the operation that failed. Otherwise, the PMTU detection can't
+ work and the server will be marked down.
+ Secondly, it is important that such errors not leak to the
+ application layer. Map them to CM_ERROR_RETRY in all cases.
+
+ * Translate RX_RESTARTING to the same cache manager error code
+ for all RPC classes.
+
+ * When logging server volume instance errors to the windows
+ application event log, be sure to log the cell as well.
+ Translating from server ip address is non-trivial. Make it
+ easier for administrators triaging issues to plug the volume
+ and cell info into vos commands.
+
+ * Since unix mode bits are represented in octal in most cases
+ make sure we log them that way.
+
+ * The cm_enforceTrailingDot() function failed if there was a
+ trailing dot followed by white space.
+
+ * Rx: Do not send RX_MSGSIZE if the PMTU size did not change.
+
Since 1.5.75
* A crash could occur if a single letter share name was
dynamically evaluated as matching a cell name. This was
