3POSIX locking to servers which support CIFS POSIX Extensions
4(disabled by default controlled by proc/fs/cifs/Experimental)
5
Steve French13298de2006-03-03 10:45:19 +00006Version 1.42
7------------
8Fix slow oplock break when mounted to different servers at the same time and
Steve French60808232006-04-22 15:53:05 +00009the tids match and we try to find matching fid on wrong server. Fix read
10looping when signing required by server (2.6.16 kernel only). Fix readdir
11vs. rename race which could cause each to hang. Return . and .. even
12if server does not. Allow searches to skip first three entries and
13begin at any location. Fix oops in find_writeable_file.

Steve French12b3b8f2006-02-09 21:12:47 +000015Version 1.41
16------------
17Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
18configure stronger authentication. Fix sfu symlinks so they can
Steve French184ed212006-02-24 06:15:11 +000019be followed (not just recognized). Fix wraparound of bcc on
20read responses when buffer size over 64K and also fix wrap of
21max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
22cifs_user_read and cifs_readpages (when EAGAIN on send of smb
Steve French08547b02006-02-28 22:39:25 +000023on socket is returned over and over). Add POSIX (advisory) byte range
24locking support (requires server with newest CIFS UNIX Extensions
Steve French083d3a22006-03-03 09:53:36 +000025to the protocol implemented). Slow down negprot slightly in port 139
26RFC1001 case to give session_init time on buggy servers.

Steve French83451872005-12-01 17:12:59 -080028Version 1.40
29------------
Steve French84afc292005-12-02 13:32:45 -080030Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
Steve French0a4b92c2006-01-12 15:44:21 -080031of readpages by eliminating one extra memcpy. Allow update of file size
32from remote server even if file is open for write as long as mount is
Steve Frencheeac8042006-01-13 21:34:58 -080033directio. Recognize share mode security and send NTLM encrypted password
34on tree connect if share mode negotiated.
Steve French83451872005-12-01 17:12:59 -080035
Steve French23e7dd72005-10-20 13:44:56 -070036Version 1.39
37------------
Steve French3abb9272005-11-28 08:16:13 -080038Defer close of a file handle slightly if pending writes depend on that handle
Steve French23e7dd72005-10-20 13:44:56 -070039(this reduces the EBADF bad file handle errors that can be logged under heavy
Steve French3c50c612005-11-10 17:31:33 -080040stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
Steve French3abb9272005-11-28 08:16:13 -080041Fix SFU style symlinks and mknod needed for servers which do not support the
42CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
43dentries so files that the client sees as deleted but that later get created
Steve French6473a552005-11-29 20:20:10 -080044on the server will be recognized. Add client side permission check on setattr.
Steve French83451872005-12-01 17:12:59 -080045Timeout stuck requests better (where server has never responded or sent corrupt
46responses)
Steve French23e7dd72005-10-20 13:44:56 -070047
Steve French190fdeb2005-10-10 11:48:26 -070048Version 1.38
49------------
50Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
51to be smaller at first (but increasing) so large write performance performance
52over GigE is better. Do not hang thread on illegal byte range lock response
53from Windows (Windows can send an RFC1001 size which does not match smb size) by
54allowing an SMBs TCP length to be up to a few bytes longer than it should be.
55wsize and rsize can now be larger than negotiated buffer size if server
56supports large readx/writex, even when directio mount flag not specified.
57Write size will in many cases now be 16K instead of 4K which greatly helps
Steve French4ca9c192005-10-10 19:52:13 -070058file copy performance on lightly loaded networks. Fix oops in dnotify
Steve French1047abc2005-10-11 19:58:06 -070059when experimental config flag enabled. Make cifsFYI more granular.
Steve French190fdeb2005-10-10 11:48:26 -070060
Steve Frencheafe8702005-09-15 21:47:30 -070061Version 1.37
62------------
63Fix readdir caching when unlink removes file in current search buffer,
64and this is followed by a rewind search to just before the deleted entry.
Steve Frenche30dcf32005-09-20 20:49:16 -070065Do not attempt to set ctime unless atime and/or mtime change requested
Steve French20962432005-09-21 22:05:57 -070066(most servers throw it away anyway). Fix length check of received smbs
Steve French70ca7342005-09-22 16:32:06 -070067to be more accurate. Fix big endian problem with mapchars mount option,
68and with a field returned by statfs.
Steve Frencheafe8702005-09-15 21:47:30 -070069
Steve Frenchc46fa8a2005-08-18 20:49:57 -070070Version 1.36
71------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -070072Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
Steve French6b8edfe2005-08-23 20:26:03 -070073For these older servers, add option for passing netbios name of server in
Steve French16abbec2005-08-30 13:10:14 -070074on mount (servernetbiosname). Add suspend support for power management, to
75avoid cifsd thread preventing software suspend from working.
Steve Frenchc46fa8a2005-08-18 20:49:57 -070076Add mount option for disabling the default behavior of sending byte range lock
77requests to the server (necessary for certain applications which break with
78mandatory lock behavior such as Evolution), and also mount option for
79requesting case insensitive matching for path based requests (requesting
80case sensitive is the default).
81
Steve Frenchf4cfd692005-07-14 18:29:02 -050082Version 1.35
83------------
84Add writepage performance improvements. Fix path name conversions
85for long filenames on mounts which were done with "mapchars" mount option
Steve Frencha10faeb22005-08-22 21:38:31 -070086specified. Ensure multiplex ids do not collide. Fix case in which
87rmmod can oops if done soon after last unmount. Fix truncated
88search (readdir) output when resume filename was a long filename.
89Fix filename conversion when mapchars mount option was specified and
90filename was a long filename.
Steve Frenchf4cfd692005-07-14 18:29:02 -050091
Steve French11aa0142005-04-28 22:41:10 -070092Version 1.34
93------------
94Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
Steve French31ca3bc2005-04-28 22:41:11 -070095Do not oops if root user kills cifs oplock kernel thread or
96kills the cifsd thread (NB: killing the cifs kernel threads is not
97recommended, unmount and rmmod cifs will kill them when they are
Steve French68575472005-04-30 11:10:57 -070098no longer needed). Fix readdir to ASCII servers (ie older servers
Steve Frenchc0c3e8e2005-08-24 14:01:13 -070099which do not support Unicode) and also require asterisk.
Steve French3079ca62005-06-09 14:44:07 -0700100Fix out of memory case in which data could be written one page
101off in the page cache.
Steve French11aa0142005-04-28 22:41:10 -0700102
Steve French966ca922005-04-28 22:41:08 -0700103Version 1.33
104------------
105Fix caching problem, in which readdir of directory containing a file
106which was cached could cause the file's time stamp to be updated
107without invalidating the readahead data (so we could get stale
108file data on the client for that file even as the server copy changed).
Steve Frenchcd634992005-04-28 22:41:10 -0700109Cleanup response processing so cifsd can not loop when abnormally
110terminated.
Steve French966ca922005-04-28 22:41:08 -0700111
112
Steve Frenchf654bac2005-04-28 22:41:04 -0700113Version 1.32
Linus Torvalds1da177e2005-04-16 15:20:36 -0700114------------
115Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
116transact response for an SMB request and search entry split across two frames.
Steve Frenchf654bac2005-04-28 22:41:04 -0700117Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
118as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
119unless server explicitly claims to support them in CIFS Unix extensions
Steve Frenchad009ac2005-04-28 22:41:05 -0700120POSIX ACL capability bit. Fix packet signing when multiuser mounting with
Steve Frenchcbe04762005-04-28 22:41:05 -0700121different users from the same client to the same server. Fix oops in
Steve French6a0b4822005-04-28 22:41:05 -0700122cifs_close. Add mount option for remapping reserved characters in
123filenames (also allow recognizing files with created by SFU which have any
Steve French737b7582005-04-28 22:41:06 -0700124of these seven reserved characters, except backslash, to be recognized).
Steve French848f3fc2005-04-28 22:41:07 -0700125Fix invalid transact2 message (we were sometimes trying to interpret
Steve French099a58f2005-04-28 22:41:07 -0700126oplock breaks as SMB responses). Add ioctl for checking that the
127current uid matches the uid of the mounter (needed by umount.cifs).
128Reduce the number of large buffer allocations in cifs response processing
129(significantly reduces memory pressure under heavy stress with multiple
130processes accessing the same server at the same time).
Steve Frenchf654bac2005-04-28 22:41:04 -0700131
132Version 1.31
133------------
Linus Torvalds1da177e2005-04-16 15:20:36 -0700134Fix updates of DOS attributes and time fields so that files on NT4 servers
135do not get marked delete on close. Display sizes of cifs buffer pools in
136cifs stats. Fix oops in unmount when cifsd thread being killed by
137shutdown. Add generic readv/writev and aio support. Report inode numbers
138consistently in readdir and lookup (when serverino mount option is
139specified use the inode number that the server reports - for both lookup
140and readdir, otherwise by default the locally generated inode number is used
141for inodes created in either path since servers are not always able to
142provide unique inode numbers when exporting multiple volumes from under one
143sharename).
144
145Version 1.30
146------------
147Allow new nouser_xattr mount parm to disable xattr support for user namespace.
148Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
149(mostly affects NT4 servers) by retry with handle based network operation.
150Add new POSIX Query FS Info for returning statfs info more accurately.
151Handle passwords with multiple commas in them.
152
153Version 1.29
154------------
155Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
156Fix capabilities flags for large readx so as to allow reads larger than 64K.
157
158Version 1.28
159------------
160Add module init parm for large SMB buffer size (to allow it to be changed
161from its default of 16K) which is especially useful for large file copy
162when mounting with the directio mount option. Fix oops after
163returning from mount when experimental ExtendedSecurity enabled and
164SpnegoNegotiated returning invalid error. Fix case to retry better when
165peek returns from 1 to 3 bytes on socket which should have more data.
166Fixed path based calls (such as cifs lookup) to handle path names
167longer than 530 (now can handle PATH_MAX). Fix pass through authentication
168from Samba server to DC (Samba required dummy LM password).
169
170Version 1.27
171------------
172Turn off DNOTIFY (directory change notification support) by default
173(unless built with the experimental flag) to fix hang with KDE
174file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
175waiting on an SMB response) in SendReceive when session dies but
176reconnects quickly from another task. Add module init parms for
177minimum number of large and small network buffers in the buffer pools,
178and for the maximum number of simultaneous requests.
179
180Version 1.26
181------------
182Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
183and other POSIX CIFS compliant servers. Fix error mapping for getfacl
184to EOPNOTSUPP when server does not support posix acls on the wire. Fix
185improperly zeroed buffer in CIFS Unix extensions set times call.
186
187Version 1.25
188------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700189Fix internationalization problem in cifs readdir with filenames that map to
Alexey Dobriyan4de151d2006-03-22 00:13:35 +0100190longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
Linus Torvalds1da177e2005-04-16 15:20:36 -0700191for readdir to netapp servers. Fix search rewind (seek into readdir to return
192non-consecutive entries). Do not do readdir when server negotiates
193buffer size to small to fit filename. Add support for reading POSIX ACLs from
194the server (add also acl and noacl mount options).
195
196Version 1.24
197------------
198Optionally allow using server side inode numbers, rather than client generated
199ones by specifying mount option "serverino" - this is required for some apps
200to work which double check hardlinked files and have persistent inode numbers.
201
202Version 1.23
203------------
204Multiple bigendian fixes. On little endian systems (for reconnect after
205network failure) fix tcp session reconnect code so we do not try first
206to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
207as directories rather than symlinks because we can do follow link on them.
208
209Version 1.22
210------------
211Add config option to enable XATTR (extended attribute) support, mapping
212xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
213minor fixes pointed out by the Stanford SWAT checker (mostly missing
214or out of order NULL pointer checks in little used error paths).
215
216Version 1.21
217------------
218Add new mount parm to control whether mode check (generic_permission) is done
219on the client. If Unix extensions are enabled and the uids on the client
220and server do not match, client permission checks are meaningless on
221server uids that do not exist on the client (this does not affect the
222normal ACL check which occurs on the server). Fix default uid
223on mknod to match create and mkdir. Add optional mount parm to allow
224override of the default uid behavior (in which the server sets the uid
225and gid of newly created files). Normally for network filesystem mounts
226user want the server to set the uid/gid on newly created files (rather than
227using uid of the client processes you would in a local filesystem).
228
229Version 1.20
230------------
231Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
232info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
233(in build_wildcard_path_from_dentry). Fix mknod to pass type field
234(block/char/fifo) properly. Remove spurious mount warning log entry when
235credentials passed as mount argument. Set major/minor device number in
236inode for block and char devices when unix extensions enabled.
237
238Version 1.19
239------------
240Fix /proc/fs/cifs/Stats and DebugData display to handle larger
241amounts of return data. Properly limit requests to MAX_REQ (50
242is the usual maximum active multiplex SMB/CIFS requests per server).
243Do not kill cifsd (and thus hurt the other SMB session) when more than one
244session to the same server (but with different userids) exists and one
245of the two user's smb sessions is being removed while leaving the other.
246Do not loop reconnecting in cifsd demultiplex thread when admin
247kills the thread without going through unmount.
248
249Version 1.18
250------------
251Do not rename hardlinked files (since that should be a noop). Flush
252cached write behind data when reopening a file after session abend,
253except when already in write. Grab per socket sem during reconnect
254to avoid oops in sendmsg if overlapping with reconnect. Do not
255reset cached inode file size on readdir for files open for write on
256client.
257
258
259Version 1.17
260------------
261Update number of blocks in file so du command is happier (in Linux a fake
262blocksize of 512 is required for calculating number of blocks in inode).
263Fix prepare write of partial pages to read in data from server if possible.
264Fix race on tcpStatus field between unmount and reconnection code, causing
265cifsd process sometimes to hang around forever. Improve out of memory
266checks in cifs_filldir
267
268Version 1.16
269------------
270Fix incorrect file size in file handle based setattr on big endian hardware.
271Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
272and closing file structs in writepage/partialpagewrite. Add statistics
273for each mounted share (new menuconfig option). Fix endianness problem in
274volume information displayed in /proc/fs/cifs/DebugData (only affects
275affects big endian architectures). Prevent renames while constructing
276path names for open, mkdir and rmdir.
277
278Version 1.15
279------------
280Change to mempools for alloc smb request buffers and multiplex structs
281to better handle low memory problems (and potential deadlocks).
282
283Version 1.14
284------------
285Fix incomplete listings of large directories on Samba servers when Unix
286extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
287rename deadlock when writing out dirty pages at same time.
288
289Version 1.13
290------------
291Fix open of files in which O_CREATE can cause the mode to change in
292some cases. Fix case in which retry of write overlaps file close.
293Fix PPC64 build error. Reduce excessive stack usage in smb password
294hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
295
296Version 1.12
297------------
298Fixes for large file copy, signal handling, socket retry, buffer
299allocation and low memory situations.
300
301Version 1.11
302------------
303Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
304also now allowing support for specifying client netbiosname. NT4 support added.
305
306Version 1.10
307------------
308Fix reconnection (and certain failed mounts) to properly wake up the
309blocked users thread so it does not seem hung (in some cases was blocked
310until the cifs receive timeout expired). Fix spurious error logging
311to kernel log when application with open network files killed.
312
313Version 1.09
314------------
315Fix /proc/fs module unload warning message (that could be logged
316to the kernel log). Fix intermittent failure in connectathon
317test7 (hardlink count not immediately refreshed in case in which
318inode metadata can be incorrectly kept cached when time near zero)
319
320Version 1.08
321------------
322Allow file_mode and dir_mode (specified at mount time) to be enforced
323locally (the server already enforced its own ACLs too) for servers
324that do not report the correct mode (do not support the
325CIFS Unix Extensions).
326
327Version 1.07
328------------
329Fix some small memory leaks in some unmount error paths. Fix major leak
330of cache pages in readpages causing multiple read oriented stress
331testcases (including fsx, and even large file copy) to fail over time.
332
333Version 1.06
334------------
335Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
336This allows files that differ only in case and improves performance of file
337creation and file open to such servers. Fix semaphore conflict which causes
338slow delete of open file to Samba (which unfortunately can cause an oplock
339break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
340
341Version 1.05
342------------
343fixes to cifs_readpages for fsx test case
344
345Version 1.04
346------------
347Fix caching data integrity bug when extending file size especially when no
348oplock on file. Fix spurious logging of valid already parsed mount options
349that are parsed outside of the cifs vfs such as nosuid.
350
351
352Version 1.03
353------------
354Connect to server when port number override not specified, and tcp port
355unitialized. Reset search to restart at correct file when kernel routine
356filldir returns error during large directory searches (readdir).
357
358Version 1.02
359------------
360Fix caching problem when files opened by multiple clients in which
361page cache could contain stale data, and write through did
362not occur often enough while file was still open when read ahead
363(read oplock) not allowed. Treat "sep=" when first mount option
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700364as an override of comma as the default separator between mount
Linus Torvalds1da177e2005-04-16 15:20:36 -0700365options.
366
367Version 1.01
368------------
369Allow passwords longer than 16 bytes. Allow null password string.
370
371Version 1.00
372------------
373Gracefully clean up failed mounts when attempting to mount to servers such as
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700374Windows 98 that terminate tcp sessions during protocol negotiation. Handle
Linus Torvalds1da177e2005-04-16 15:20:36 -0700375embedded commas in mount parsing of passwords.
376
377Version 0.99
378------------
379Invalidate local inode cached pages on oplock break and when last file
380instance is closed so that the client does not continue using stale local
381copy rather than later modified server copy of file. Do not reconnect
382when server drops the tcp session prematurely before negotiate
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700383protocol response. Fix oops in reopen_file when dentry freed. Allow
Linus Torvalds1da177e2005-04-16 15:20:36 -0700384the support for CIFS Unix Extensions to be disabled via proc interface.
385

467Finish support for Linux 2.5 open/create changes, which removes the
468redundant NTCreate/QPathInfo/close that was sent during file create.
469Enable oplock by default. Enable packet signing by default (needed to
470access many recent Windows servers)
471
472Version 0.83
473------------
474Fix oops when mounting to long server names caused by inverted parms to kmalloc.
475Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
476we will choose a cifs user session (smb uid) that better matches the local

513Fix display of NTFS DFS junctions to display as symlinks.
514They are the network equivalent. Fix oops in
515cifs_partialpagewrite caused by missing spinlock protection
516of openfile linked list. Allow writebehind caching errors to
517be returned to the application at file close.
518
519Version 0.76
520------------
521Clean up options displayed in /proc/mounts by show_options to

527presence or absence of read only dos attribute in mode
528bits for servers that do not support CIFS Unix extensions.
529Fix shortened results on readdir of large directories to
530servers supporting CIFS Unix extensions (caused by
531incorrect resume key).
532
533Version 0.74

552symlink routines.
553
554Version 0.70
555------------
556Fix oops in get dfs referral (triggered when null path sent in to
557mount). Add support for overriding rsize at mount time.
558
559Version 0.69
560------------
561Fix buffer overrun in readdir which caused intermittent kernel oopses.
562Fix writepage code to release kmap on write data. Allow "-ip=" new
563mount option to be passed in on parameter distinct from the first part
564(server name portion of) the UNC name. Allow override of the
565tcp port of the target server via new mount option "-port="
566
567Version 0.68
568------------
569Fix search handle leak on rewind. Fix setuid and gid so that they are
570reflected in the local inode immediately. Cleanup of whitespace
571to make 2.4 and 2.5 versions more consistent.
572
573
574Version 0.67
575------------
576Fix signal sending so that captive thread (cifsd) exits on umount
577(which was causing the warning in kmem_cache_free of the request buffers
578at rmmod time). This had broken as a sideeffect of the recent global
579kernel change to daemonize. Fix memory leak in readdir code which
580showed up in "ls -R" (and applications that did search rewinding).
581
582Version 0.66
583------------
584Reconnect tids and fids after session reconnection (still do not
585reconnect byte range locks though). Fix problem caching
586lookup information for directory inodes, improving performance,
587especially in deep directory trees. Fix various build warnings.
588
589Version 0.65
590------------
591Finish fixes to commit write for caching/readahead consistency. fsx

593was interrupted by a signal.
594
595Version 0.64
596------------
597Fix data corruption (in partial page after truncate) that caused fsx to
598fail to Windows servers. Cleaned up some extraneous error logging in
599common error paths. Add generic sendfile support.
600
601Version 0.63
602------------
603Fix memory leak in AllocMidQEntry.
604Finish reconnection logic, so connection with server can be dropped
605(or server rebooted) and the cifs client will reconnect.
606
607Version 0.62
608------------
609Fix temporary socket leak when bad userid or password specified
610(or other SMBSessSetup failure). Increase maximum buffer size to slightly
611over 16K to allow negotiation of up to Samba and Windows server default read
612sizes. Add support for readpages
613
614Version 0.61
615------------
616Fix oops when username not passed in on mount. Extensive fixes and improvements
617to error logging (strip redundant newlines, change debug macros to ensure newline
618passed in and to be more consistent). Fix writepage wrong file handle problem,
619a readonly file handle could be incorrectly used to attempt to write out
620file updates through the page cache to multiply open files. This could cause
621the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
622shares to the same Windows server when using different usernames
623(doing this to Samba servers worked but Windows was rejecting it) - now it is
624possible to use different userids when connecting to the same server from a
625Linux client. Fix oops when treeDisconnect called during unmount on
626previously freed socket.
627
628Version 0.60
629------------

636requirement). Add readlink support for Windows junction points (directory symlinks).
637
638Version 0.58
639------------
640Changed read and write to go through pagecache. Added additional address space operations.
641Memory mapped operations now working.
642
643Version 0.57
644------------
645Added writepage code for additional memory mapping support. Fixed leak in xids causing
646the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
647every stat call. Additional formatting cleanup.
648
649Version 0.56
650------------
651Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
652
653Version 0.55
654------------
655Fixes from Zwane Mwaikambo for adding missing return code checking in a few places.

657the smb session and tree connection and mid related global variables.
658
659Version 0.54
660------------
661Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
662changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
663buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
664
665Version 0.53
666------------
667More stylistic updates to better match kernel style. Add additional statistics
668for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
669and CIFS Packet Signing enablement.
670

721
722Version 0.41
723------------
724Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700725files now return the correct number of links on fstat as they are repeatedly linked and unlinked.
Linus Torvalds1da177e2005-04-16 15:20:36 -0700726
727Version 0.40
728------------
729Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
730session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
731Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs

750Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
751Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
752although corresponding function not fully implemented in the vfs yet
753
754Version 0.34
755------------
756Fixed dentry caching bug, misc. cleanup
757
758Version 0.33
759------------
760Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
761on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
762Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
763
764Version 0.32
765------------
766Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
767and tested against Samba 2.2.5
768
769
770Version 0.31
771------------
7721) Fixed lockrange to be correct (it was one byte too short)
773
7742) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
775show range as locked when there is a conflict with an existing lock.
776
7773) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
778in most cases. Eventually will offer optional ability to query server for the correct perms.
779
7803) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
781but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
782session)
783
7844) Fixed error logging of valid mount options
785
7865) Removed logging of password field.
787
7886) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
789and cleaned them up and made them more consistent with other cifs functions.
790
7917) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700792(with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
Linus Torvalds1da177e2005-04-16 15:20:36 -0700793nor is the symlink support using the Unix extensions
