Since 1.5.57
* Discovered that XP/2003 supports a variant on recvmsg
called WSARecvMsg. The input parameters are mostly
compatible with the Posix recvmsg. This will save
multiple memcpy() calls per received packet.
* Discovered that Vista/2008 supports a variant on
sendmsg called WSASendMsg. The input parameters
are mostly compatible with the Posix sendmsg. This
will save multiple memcpy() calls per sent packet.
* Exporting rx_ReadProc32, rx_WriteProc32 from afsrpc.dll
and utilizing rx_ReadProc32 from within the cache manager
as part of the FetchData operations. rx_ReadProc32 and
rx_WriteProc32 are optimized versions of rx_ReadProc and
rx_WriteProc for use when reading 32-bit integer values.
* The Network Identity Manager AFS provider now reports
progress events. These provide a better user experience
with Network Identity Manager 2.0.
* [RT 124293] A race condition exists which permits the
scp field of the an smb_fid_t object to become invalid
after a request on the smb_fid_t has begun. Remove the
race by protecting all access to the scp field with the
smb_fid_t mx mutex and obtaining a local reference on
the cm_scache_t object for the length of the request.
* [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.
* Improve consistency of the bad data version value used for
cm_scache fields.
* 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.
* Fix vos.exe so that it can work with very large volume
identifiers
* Remove symlink recursion tests and increase max symlink count
to 64 from 16.
Since 1.5.56
* Undo the "UAC manifest fix" applied to afs_config.exe.
