User-Visible OpenAFS Changes
+OpenAFS 1.6.0 (in progress)
+
+ All platforms
+
+ * vos now properly deals with matching sites when servers are
+ multihomed.
+
+ * Don't stop Rx keepalives after an ackall is received, avoiding
+ spurious connection timeouts. (128848)
+
+ * Don't retry Rx calls on channels returning busy errors and improve
+ Rx busy call channel error handling. (128671)
+
+ * Properly enable Rx connection hard timeouts.
+
+ * Initialize rx_multi lock before use.
+
+ * Avoid spurious crashes when initializing in "backup" client.
+
+ * Revert UUID support in vos.
+
+ * pt_util fixed to properly create new databases.
+
+ * MTU discovery now properly shut down on call reset.
+
+ * Documentation updates.
+
+ All server platforms
+
+ * A file descriptor leak which could result in corrupted files in the
+ fileserver was fixed. An IMMEDIATE upgrade from previous 1.6 release
+ candidates as well as 1.5 release fileserver is recommended.
+
+ * Fix ptserver supergroups support on 64 bit platforms.
+
+ * Demand attach salvaging doesn't use freed volume pointers.
+
+ * Properly hold host lock during host enumeration in fileserver.
+
+ * Attempt to recovery more quickly from timed out volume release
+ transactions.
+
+ * Auditing now properly byte order swaps IP addresses when printing.
+
+ * vos split now has improved error handling.
+
+ * Many changes to again support Windows fileservers.
+
+ * During volume removal, data removal speed improved.
+
+ * Improve CPU utilization during volume attaching by DAFS.
+
+ * In salvager check-only mode, avoid potentially fixing a vnode.
+
+ * Fix support for large (greater than 2gb) volume special files.
+
+ * Salvager will not crash if multiple or bad volume link tables are
+ encountered.
+
+ * Avoid erroneous full dump by remembering which sites were out of
+ date at the start of the release.
+
+ * A deleted volume can now be recreated properly.
+
+ * Callbacks are again not broken during whole partition salvages.
+
+ * Positional vectored IO fixed for largefile (>2GB) capable systems.
+
+ * Fileserver per-client thread usage again properly enforced.
+
+ * Anonymous dropbox support improved and drawbacks documented.
+
+ * Demand attach: ensure vnodes are not reallocated while in use due to
+ volume bitmap errors.
+
+ * Properly support large volume numbers (larger than 2147483647).
+
+ * Allow salvager to be run manually again when DAFS is being
+ used. (129458)
+
+ Microsoft Windows:
+
+ * afs_config will not longer set the Tray Icon State in the registry
+ if the checkbox is not present in the dialog. (128591)
+
+ * 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.
+
+ * When the data version of a mountpoint or symlink changes, the target
+ string in the cm_scache_t object must be cleared.
+
+ * "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
+
+ * Icon tray state now conditionally set. (128591)
+
+ * Properly create new cell mount points in freelance mode.
+
+ * Avoid recursive offline volume checks.

+
+ * Avoid extra runs of vcache freeing routine. (128756)
+
+ * Perform vcache eviction via a fast path before visiting vcaches
+ where sleep is needed.
+
+ * Improve RPM building tools.
+
+ * setpag() errors are now properly reported.
+

+
+ * Properly handle setpag errors. PAGs are not supported.
+
+ * Check for unloaded kernel extensions when decoding AFS panics.
+
+ * Disable "get tokens at login" in prefs pane if AD authentication
+ plugin is configured.
+
+ * aklog AuthorizationPlugin now provided.
+
+ * Preferences Pane behavior fixed for 1.6 series (version detection is
+ used to select default behavior).
+
+ * A potential kernel panic during bulkstat operations is
+ fixed. (128511)
+
+ * 64-bit MacOS kernel performance is greatly improved. (128934)
+
+ OpenBSD
+
+ * Bug fixes for issues introduced previously in 1.5 series.
