+Version 1.31
+------------
+Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
+transact response for an SMB request and search entry split across two frames.
+Fix updates of DOS attributes and time fields so that files on NT4 servers
+do not get marked delete on close. Display sizes of cifs buffer pools in
+cifs stats. Fix oops in unmount when cifsd thread being killed by 
+shutdown. Add generic readv/writev and aio support. Report inode numbers 
+consistently in readdir and lookup (when serverino mount option is
+specified use the inode number that the server reports - for both lookup
+and readdir, otherwise by default the locally generated inode number is used
+for inodes created in either path since servers are not always able to 
+provide unique inode numbers when exporting multiple volumes from under one
+sharename).
+
+Version 1.30
+------------
+Allow new nouser_xattr mount parm to disable xattr support for user namespace.
+Do not flag user_xattr mount parm in dmesg.  Retry failures setting file time  
+(mostly affects NT4 servers) by retry with handle based network operation. 
+Add new POSIX Query FS Info for returning statfs info more accurately.
+Handle passwords with multiple commas in them.
+
+Version 1.29
+------------
+Fix default mode in sysfs of cifs module parms.  Remove old readdir routine.
+Fix capabilities flags for large readx so as to allow reads larger than 64K.
+
+Version 1.28
+------------
+Add module init parm for large SMB buffer size (to allow it to be changed
+from its default of 16K) which is especially useful for large file copy
+when mounting with the directio mount option. Fix oops after 
+returning from mount when experimental ExtendedSecurity enabled and
+SpnegoNegotiated returning invalid error. Fix case to retry better when 
+peek returns from 1 to 3 bytes on socket which should have more data.
+Fixed path based calls (such as cifs lookup) to handle path names
+longer than 530 (now can handle PATH_MAX). Fix pass through authentication
+from Samba server to DC (Samba required dummy LM password).
+
+Version 1.27
+------------
+Turn off DNOTIFY (directory change notification support) by default
+(unless built with the experimental flag) to fix hang with KDE
+file browser. Fix DNOTIFY flag mappings.  Fix hang (in wait_event
+waiting on an SMB response) in SendReceive when session dies but
+reconnects quickly from another task.  Add module init  parms for
+minimum number of large and small network buffers in the buffer pools,
+and for the maximum number of simultaneous requests.
+
+Version 1.26
+------------
+Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
+and other POSIX CIFS compliant servers.  Fix error mapping for getfacl 
+to EOPNOTSUPP when server does not support posix acls on the wire. Fix 
+improperly zeroed buffer in CIFS Unix extensions set times call. 
+
+Version 1.25
+------------
+Fix internationlization problem in cifs readdir with filenames that map to 
+longer UTF8 strings than the string on the wire was in Unicode.  Add workaround
+for readdir to netapp servers. Fix search rewind (seek into readdir to return 
+non-consecutive entries).  Do not do readdir when server negotiates 
+buffer size to small to fit filename. Add support for reading POSIX ACLs from
+the server (add also acl and noacl mount options).
+
+Version 1.24
+------------
+Optionally allow using server side inode numbers, rather than client generated
+ones by specifying mount option "serverino" - this is required for some apps
+to work which double check hardlinked files and have persistent inode numbers.
+
+Version 1.23
+------------
+Multiple bigendian fixes. On little endian systems (for reconnect after
+network failure) fix tcp session reconnect code so we do not try first
+to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
+as directories rather than symlinks because we can do follow link on them.
+
+Version 1.22
+------------
+Add config option to enable XATTR (extended attribute) support, mapping
+xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
+minor fixes pointed out by the Stanford SWAT checker (mostly missing
+or out of order NULL pointer checks in little used error paths).
+
+Version 1.21
+------------
+Add new mount parm to control whether mode check (generic_permission) is done
+on the client.  If Unix extensions are enabled and the uids on the client
+and server do not match, client permission checks are meaningless on
+server uids that do not exist on the client (this does not affect the
+normal ACL check which occurs on the server).  Fix default uid
+on mknod to match create and mkdir. Add optional mount parm to allow
+override of the default uid behavior (in which the server sets the uid
+and gid of newly created files). Normally for network filesystem mounts
+user want the server to set the uid/gid on newly created files (rather than 
+using uid of the client processes you would in a local filesystem).
+
+Version 1.20
+------------
+Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
+info into /proc/fs/cifs/DebugData.  Fix oops in rare oops in readdir 
+(in build_wildcard_path_from_dentry).  Fix mknod to pass type field
+(block/char/fifo) properly.  Remove spurious mount warning log entry when
+credentials passed as mount argument. Set major/minor device number in
+inode for block and char devices when unix extensions enabled.
+
+Version 1.19
+------------
+Fix /proc/fs/cifs/Stats and DebugData display to handle larger
+amounts of return data. Properly limit requests to MAX_REQ (50
+is the usual maximum active multiplex SMB/CIFS requests per server).
+Do not kill cifsd (and thus hurt the other SMB session) when more than one
+session to the same server (but with different userids) exists and one
+of the two user's smb sessions is being removed while leaving the other.
+Do not loop reconnecting in cifsd demultiplex thread when admin
+kills the thread without going through unmount.
+
+Version 1.18
+------------
+Do not rename hardlinked files (since that should be a noop). Flush
+cached write behind data when reopening a file after session abend,
+except when already in write. Grab per socket sem during reconnect 
+to avoid oops in sendmsg if overlapping with reconnect. Do not
+reset cached inode file size on readdir for files open for write on 
+client.
+
+
+Version 1.17
+------------
+Update number of blocks in file so du command is happier (in Linux a fake
+blocksize of 512 is required for calculating number of blocks in inode).
+Fix prepare write of partial pages to read in data from server if possible.
+Fix race on tcpStatus field between unmount and reconnection code, causing
+cifsd process sometimes to hang around forever. Improve out of memory
+checks in cifs_filldir
+
+Version 1.16
+------------
+Fix incorrect file size in file handle based setattr on big endian hardware.
+Fix oops in build_path_from_dentry when out of memory.  Add checks for invalid
+and closing file structs in writepage/partialpagewrite.  Add statistics
+for each mounted share (new menuconfig option). Fix endianness problem in
+volume information displayed in /proc/fs/cifs/DebugData (only affects
+affects big endian architectures). Prevent renames while constructing
+path names for open, mkdir and rmdir.
+
+Version 1.15
+------------
+Change to mempools for alloc smb request buffers and multiplex structs
+to better handle low memory problems (and potential deadlocks).
+
+Version 1.14
+------------
+Fix incomplete listings of large directories on Samba servers when Unix
+extensions enabled.  Fix oops when smb_buffer can not be allocated. Fix
+rename deadlock when writing out dirty pages at same time.
+
+Version 1.13
+------------
+Fix open of files in which O_CREATE can cause the mode to change in
+some cases. Fix case in which retry of write overlaps file close.
+Fix PPC64 build error.  Reduce excessive stack usage in smb password
+hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
+
+Version 1.12
+------------
+Fixes for large file copy, signal handling, socket retry, buffer
+allocation and low memory situations.
+
+Version 1.11
+------------
+Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
+also now allowing support for specifying client netbiosname.  NT4 support added.
+
+Version 1.10
+------------
+Fix reconnection (and certain failed mounts) to properly wake up the
+blocked users thread so it does not seem hung (in some cases was blocked
+until the cifs receive timeout expired). Fix spurious error logging
+to kernel log when application with open network files killed. 
+
+Version 1.09
+------------
+Fix /proc/fs module unload warning message (that could be logged
+to the kernel log). Fix intermittent failure in connectathon
+test7 (hardlink count not immediately refreshed in case in which
+inode metadata can be incorrectly kept cached when time near zero)
+
+Version 1.08
+------------
+Allow file_mode and dir_mode (specified at mount time) to be enforced
+locally (the server already enforced its own ACLs too) for servers
+that do not report the correct mode (do not support the 
+CIFS Unix Extensions).
+
+Version 1.07
+------------
+Fix some small memory leaks in some unmount error paths. Fix major leak
+of cache pages in readpages causing multiple read oriented stress
+testcases (including fsx, and even large file copy) to fail over time. 
+
+Version 1.06
+------------
+Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
+This allows files that differ only in case and improves performance of file
+creation and file open to such servers.  Fix semaphore conflict which causes 
+slow delete of open file to Samba (which unfortunately can cause an oplock
+break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
+
+Version 1.05
+------------
+fixes to cifs_readpages for fsx test case
+
+Version 1.04
+------------
+Fix caching data integrity bug when extending file size especially when no
+oplock on file.  Fix spurious logging of valid already parsed mount options
+that are parsed outside of the cifs vfs such as nosuid.
+
+
+Version 1.03
+------------
+Connect to server when port number override not specified, and tcp port
+unitialized.  Reset search to restart at correct file when kernel routine
+filldir returns error during large directory searches (readdir). 
+
+Version 1.02
+------------
+Fix caching problem when files opened by multiple clients in which 
+page cache could contain stale data, and write through did
+not occur often enough while file was still open when read ahead
+(read oplock) not allowed.  Treat "sep=" when first mount option
+as an overrride of comma as the default separator between mount
+options. 
+
+Version 1.01
+------------
+Allow passwords longer than 16 bytes. Allow null password string.
+
+Version 1.00
+------------
+Gracefully clean up failed mounts when attempting to mount to servers such as
+Windows 98 that terminate tcp sessions during prototocol negotiation.  Handle
+embedded commas in mount parsing of passwords.
+
+Version 0.99
+------------
+Invalidate local inode cached pages on oplock break and when last file
+instance is closed so that the client does not continue using stale local
+copy rather than later modified server copy of file.  Do not reconnect
+when server drops the tcp session prematurely before negotiate
+protocol response.  Fix oops in roepen_file when dentry freed.  Allow
+the support for CIFS Unix Extensions to be disabled via proc interface.
+
+Version 0.98
+------------
+Fix hang in commit_write during reconnection of open files under heavy load.
+Fix unload_nls oops in a mount failure path. Serialize writes to same socket
+which also fixes any possible races when cifs signatures are enabled in SMBs
+being sent out of signature sequence number order.    
+
+Version 0.97
+------------
+Fix byte range locking bug (endian problem) causing bad offset and
+length.
+
+Version 0.96
+------------
+Fix oops (in send_sig) caused by CIFS unmount code trying to
+wake up the demultiplex thread after it had exited. Do not log
+error on harmless oplock release of closed handle.
+
+Version 0.95
+------------
+Fix unsafe global variable usage and password hash failure on gcc 3.3.1
+Fix problem reconnecting secondary mounts to same server after session 
+failure.  Fix invalid dentry - race in mkdir when directory gets created
+by another client between the lookup and mkdir.
+ 
+Version 0.94
+------------
+Fix to list processing in reopen_files. Fix reconnection when server hung

+Retry on ENOSPC and EAGAIN socket errors.
+
+Version 0.87
+------------
+Fix oops on big endian readdir.  Set blksize to be even power of two (2**blkbits) to fix

+access many recent Windows servers)
+
+Version 0.83
+------------
+Fix oops when mounting to long server names caused by inverted parms to kmalloc.
+Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
+we will choose a cifs user session (smb uid) that better matches the local

+code (distributed caching) to properly send response to oplock
+break from server.
+
+Version 0.81

+presence or absence of read only dos attribute in mode
+bits for servers that do not support CIFS Unix extensions.
+Fix shortened results on readdir of large directories to
+servers supporting CIFS Unix extensions (caused by
+incorrect resume key).
+

+
+Version 0.73
+------------
+unload nls if mount fails.
+
+Version 0.72
+------------
+Add resume key support to search (readdir) code to workaround
+Windows bug.  Add /proc/fs/cifs/LookupCacheEnable which
+allows disabling caching of attribute information for
+lookups.

+Fix buffer overrun in readdir which caused intermittent kernel oopses.
+Fix writepage code to release kmap on write data.  Allow "-ip=" new 
+mount option to be passed in on parameter distinct from the first part
+(server name portion of) the UNC name.  Allow override of the
+tcp port of the target server via new mount option "-port="  
+
+Version 0.68
+------------
+Fix search handle leak on rewind.  Fix setuid and gid so that they are 
+reflected in the local inode immediately.  Cleanup of whitespace
+to make 2.4 and 2.5 versions more consistent.
+
+
+Version 0.67
+------------
+Fix signal sending so that captive thread (cifsd) exits on umount 
+(which was causing the warning in kmem_cache_free of the request buffers
+at rmmod time).  This had broken as a sideeffect of the recent global
+kernel change to daemonize.  Fix memory leak in readdir code which
+showed up in "ls -R" (and applications that did search rewinding).
+
+Version 0.66
+------------
+Reconnect tids and fids after session reconnection (still do not
+reconnect byte range locks though).  Fix problem caching
+lookup information for directory inodes, improving performance,

+------------
+Fix data corruption (in partial page after truncate) that caused fsx to
+fail to Windows servers.  Cleaned up some extraneous error logging in
+common error paths.  Add generic sendfile support.
+
+Version 0.63
+------------
+Fix memory leak in AllocMidQEntry.
+Finish reconnection logic, so connection with server can be dropped
+(or server rebooted) and the cifs client will reconnect.  
+
+Version 0.62
+------------
+Fix temporary socket leak when bad userid or password specified 
+(or other SMBSessSetup failure).  Increase maximum buffer size to slightly
+over 16K to allow negotiation of up to Samba and Windows server default read 
+sizes.  Add support for readpages
+
+Version 0.61
+------------
+Fix oops when username not passed in on mount.  Extensive fixes and improvements
+to error logging (strip redundant newlines, change debug macros to ensure newline
+passed in and to be more consistent).  Fix writepage wrong file handle problem,
+a readonly file handle could be incorrectly used to attempt to write out
+file updates through the page cache to multiply open files.  This could cause
+the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
+shares to the same Windows server when using different usernames
+(doing this to Samba servers worked but Windows was rejecting it) - now it is
+possible to use different userids when connecting to the same server from a
+Linux client. Fix oops when treeDisconnect called during unmount on
+previously freed socket.
+
+Version 0.60

+Also included a modified version of his fix to protect global list manipulation of
+the smb session and tree connection and mid related global variables.
+
+Version 0.54
+------------
+Fix problem with captive thread hanging around at unmount time.  Adjust to 2.5.42-pre
+changes to superblock layout.   Remove wasteful allocation of smb buffers (now the send 
+buffer is reused for responses).  Add more oplock handling. Additional minor cleanup.
+
+Version 0.53

+More stylistic updates to better match kernel style.  Add additional statistics
+for filesystem which can be viewed via /proc/fs/cifs.  Add more pieces of NTLMv2
+and CIFS Packet Signing enablement.
+
+Version 0.52

+Version 0.44
+------------
+Various big endian fixes for servers with Unix extensions such as Samba
+
+Version 0.43
+------------
+Various FindNext fixes for incorrect filenames on large directory searches on big endian
+clients.  basic posix file i/o tests now work on big endian machines, not just le

+files now return the correct rumber of links on fstat as they are repeatedly linked and unlinked.
+
+Version 0.40
+------------
+Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
+session advanced session authentication).  Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
+Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
+(which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).
+
+Version 0.38
+------------
+Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
+it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
+

+------------
+Rewrote much of connection and mount/unmount logic to handle bugs with
+multiple uses to same share, multiple users to same server etc.
+
+Version 0.36
+------------
+Fixed major problem with dentry corruption (missing call to dput)
+
+Version 0.35

+------------
+Fixed dentry caching bug, misc. cleanup 
+

+on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
+Support for STATUS codes (newer 32 bit NT error codes) added.  DFS support begun to be added.
+
+Version 0.32
+------------
+Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
+and tested against Samba 2.2.5
+
+
+Version 0.31
+------------
+1) Fixed lockrange to be correct (it was one byte too short)
+
+2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly 
+show range as locked when there is a conflict with an existing lock.
+
+3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
+in most cases.  Eventually will offer optional ability to query server for the correct perms.
+
+3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded 
+but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
+session) 
+
+4) Fixed error logging of valid mount options
+
+5) Removed logging of password field.
+
+6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
+and cleaned them up and made them more consistent with other cifs functions. 
+
+7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways 
+(with or without Unix exentions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
+nor is the symlink support using the Unix extensions
+
+8) Started adding the readlink and follow_link code 
+
