2------------
3Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
Steve French4b952a92006-10-30 21:46:13 +00004Allow null user to be specified on mount ("username="). Do not return
5EINVAL on readdir when filldir fails due to overwritten blocksize
Steve French8e87d4d2006-11-02 03:45:24 +00006(fixes FC problem). Return error in rename 2nd attempt retry (ie report
7if rename by handle also fails, after rename by path fails, we were
Steve French33ec32f2006-12-08 04:14:28 +00008not reporting whether the retry worked or not). Fix NTLMv2 to
9work to Windows servers (mount with option "sec=ntlmv2").

Steve French3a5ff612006-07-14 22:37:11 +000011Version 1.45
12------------
13Do not time out lockw calls when using posix extensions. Do not
14time out requests if server still responding reasonably fast
Steve Frenche466e482006-08-15 13:07:18 +000015on requests on other threads. Improve POSIX locking emulation,
16(lock cancel now works, and unlock of merged range works even
17to Windows servers now). Fix oops on mount to lanman servers
Steve Frenchea4c07d2006-08-16 19:44:25 +000018(win9x, os/2 etc.) when null password. Do not send listxattr
Steve French2fe87f02006-09-21 07:02:52 +000019(SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
20problem (instantiate inodes/dentries in right order for readdir).
Steve French3a5ff612006-07-14 22:37:11 +000021
Steve French39798772006-05-31 22:40:51 +000022Version 1.44
23------------
24Rewritten sessionsetup support, including support for legacy SMB
25session setup needed for OS/2 and older servers such as Windows 95 and 98.
Steve French5bafd762006-06-07 00:18:43 +000026Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
27so we can do search (ls etc.) to OS/2. Do not send NTCreateX
28or recent levels of FindFirst unless server says it supports NT SMBs
Steve French1717ffc2006-06-08 05:41:32 +000029(instead use legacy equivalents from LANMAN dialect). Fix to allow
30NTLMv2 authentication support (now can use stronger password hashing
Steve French750d1152006-06-27 06:28:30 +000031on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
32Allow override of global cifs security flags on mount via "sec=" option(s).
Steve French39798772006-05-31 22:40:51 +000033
Steve Frenchfc94cdb2006-05-30 18:03:32 +000034Version 1.43
35------------
36POSIX locking to servers which support CIFS POSIX Extensions
Steve Frencha878fb22006-05-30 18:04:19 +000037(disabled by default controlled by proc/fs/cifs/Experimental).
38Handle conversion of long share names (especially Asian languages)
Steve French26a21b92006-05-31 18:05:34 +000039to Unicode during mount. Fix memory leak in sess struct on reconnect.
40Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
41cifs open which helps rare case when setpathinfo fails or server does
42not support it.
Steve Frenchfc94cdb2006-05-30 18:03:32 +000043
Steve French13298de2006-03-03 10:45:19 +000044Version 1.42
45------------
46Fix slow oplock break when mounted to different servers at the same time and
Steve French60808232006-04-22 15:53:05 +000047the tids match and we try to find matching fid on wrong server. Fix read
48looping when signing required by server (2.6.16 kernel only). Fix readdir
49vs. rename race which could cause each to hang. Return . and .. even
50if server does not. Allow searches to skip first three entries and
51begin at any location. Fix oops in find_writeable_file.
Steve French13298de2006-03-03 10:45:19 +000052
Steve French12b3b8f2006-02-09 21:12:47 +000053Version 1.41
54------------
55Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
56configure stronger authentication. Fix sfu symlinks so they can
Steve French184ed212006-02-24 06:15:11 +000057be followed (not just recognized). Fix wraparound of bcc on
58read responses when buffer size over 64K and also fix wrap of
59max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
60cifs_user_read and cifs_readpages (when EAGAIN on send of smb
Steve French08547b02006-02-28 22:39:25 +000061on socket is returned over and over). Add POSIX (advisory) byte range
62locking support (requires server with newest CIFS UNIX Extensions
Steve French083d3a22006-03-03 09:53:36 +000063to the protocol implemented). Slow down negprot slightly in port 139
64RFC1001 case to give session_init time on buggy servers.
Steve French12b3b8f2006-02-09 21:12:47 +000065
Steve French83451872005-12-01 17:12:59 -080066Version 1.40
67------------
Steve French84afc292005-12-02 13:32:45 -080068Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
Steve French0a4b92c2006-01-12 15:44:21 -080069of readpages by eliminating one extra memcpy. Allow update of file size
70from remote server even if file is open for write as long as mount is
Steve Frencheeac8042006-01-13 21:34:58 -080071directio. Recognize share mode security and send NTLM encrypted password
72on tree connect if share mode negotiated.
Steve French83451872005-12-01 17:12:59 -080073
Steve French23e7dd72005-10-20 13:44:56 -070074Version 1.39
75------------
Steve French3abb9272005-11-28 08:16:13 -080076Defer close of a file handle slightly if pending writes depend on that handle
Steve French23e7dd72005-10-20 13:44:56 -070077(this reduces the EBADF bad file handle errors that can be logged under heavy
Steve French3c50c612005-11-10 17:31:33 -080078stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
Steve French3abb9272005-11-28 08:16:13 -080079Fix SFU style symlinks and mknod needed for servers which do not support the
80CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
81dentries so files that the client sees as deleted but that later get created
Steve French6473a552005-11-29 20:20:10 -080082on the server will be recognized. Add client side permission check on setattr.
Steve French83451872005-12-01 17:12:59 -080083Timeout stuck requests better (where server has never responded or sent corrupt
84responses)
Steve French23e7dd72005-10-20 13:44:56 -070085
Steve French190fdeb2005-10-10 11:48:26 -070086Version 1.38
87------------
88Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
89to be smaller at first (but increasing) so large write performance performance
90over GigE is better. Do not hang thread on illegal byte range lock response
91from Windows (Windows can send an RFC1001 size which does not match smb size) by
92allowing an SMBs TCP length to be up to a few bytes longer than it should be.
93wsize and rsize can now be larger than negotiated buffer size if server
94supports large readx/writex, even when directio mount flag not specified.
95Write size will in many cases now be 16K instead of 4K which greatly helps
Steve French4ca9c192005-10-10 19:52:13 -070096file copy performance on lightly loaded networks. Fix oops in dnotify
Steve French1047abc2005-10-11 19:58:06 -070097when experimental config flag enabled. Make cifsFYI more granular.
Steve French190fdeb2005-10-10 11:48:26 -070098
Steve Frencheafe8702005-09-15 21:47:30 -070099Version 1.37
100------------
101Fix readdir caching when unlink removes file in current search buffer,
102and this is followed by a rewind search to just before the deleted entry.
Steve Frenche30dcf32005-09-20 20:49:16 -0700103Do not attempt to set ctime unless atime and/or mtime change requested
Steve French20962432005-09-21 22:05:57 -0700104(most servers throw it away anyway). Fix length check of received smbs
Steve French70ca7342005-09-22 16:32:06 -0700105to be more accurate. Fix big endian problem with mapchars mount option,
106and with a field returned by statfs.
Steve Frencheafe8702005-09-15 21:47:30 -0700107
Steve Frenchc46fa8a2005-08-18 20:49:57 -0700108Version 1.36
109------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700110Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
Steve French6b8edfe2005-08-23 20:26:03 -0700111For these older servers, add option for passing netbios name of server in
Steve French16abbec2005-08-30 13:10:14 -0700112on mount (servernetbiosname). Add suspend support for power management, to
113avoid cifsd thread preventing software suspend from working.
Steve Frenchc46fa8a2005-08-18 20:49:57 -0700114Add mount option for disabling the default behavior of sending byte range lock
115requests to the server (necessary for certain applications which break with
116mandatory lock behavior such as Evolution), and also mount option for
117requesting case insensitive matching for path based requests (requesting
118case sensitive is the default).
119
Steve Frenchf4cfd692005-07-14 18:29:02 -0500120Version 1.35
121------------
122Add writepage performance improvements. Fix path name conversions
123for long filenames on mounts which were done with "mapchars" mount option
Steve Frencha10faeb22005-08-22 21:38:31 -0700124specified. Ensure multiplex ids do not collide. Fix case in which
125rmmod can oops if done soon after last unmount. Fix truncated
126search (readdir) output when resume filename was a long filename.
127Fix filename conversion when mapchars mount option was specified and
128filename was a long filename.
Steve Frenchf4cfd692005-07-14 18:29:02 -0500129
Steve French11aa0142005-04-28 22:41:10 -0700130Version 1.34
131------------
132Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
Steve French31ca3bc2005-04-28 22:41:11 -0700133Do not oops if root user kills cifs oplock kernel thread or
134kills the cifsd thread (NB: killing the cifs kernel threads is not
135recommended, unmount and rmmod cifs will kill them when they are
Steve French68575472005-04-30 11:10:57 -0700136no longer needed). Fix readdir to ASCII servers (ie older servers
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700137which do not support Unicode) and also require asterisk.
Steve French3079ca62005-06-09 14:44:07 -0700138Fix out of memory case in which data could be written one page
139off in the page cache.
Steve French11aa0142005-04-28 22:41:10 -0700140
Steve French966ca922005-04-28 22:41:08 -0700141Version 1.33
142------------
143Fix caching problem, in which readdir of directory containing a file
144which was cached could cause the file's time stamp to be updated
145without invalidating the readahead data (so we could get stale
146file data on the client for that file even as the server copy changed).
Steve Frenchcd634992005-04-28 22:41:10 -0700147Cleanup response processing so cifsd can not loop when abnormally
148terminated.
Steve French966ca922005-04-28 22:41:08 -0700149
150
Steve Frenchf654bac2005-04-28 22:41:04 -0700151Version 1.32
Linus Torvalds1da177e2005-04-16 15:20:36 -0700152------------
153Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
154transact response for an SMB request and search entry split across two frames.
Steve Frenchf654bac2005-04-28 22:41:04 -0700155Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
156as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
157unless server explicitly claims to support them in CIFS Unix extensions
Steve Frenchad009ac2005-04-28 22:41:05 -0700158POSIX ACL capability bit. Fix packet signing when multiuser mounting with
Steve Frenchcbe04762005-04-28 22:41:05 -0700159different users from the same client to the same server. Fix oops in
Steve French6a0b4822005-04-28 22:41:05 -0700160cifs_close. Add mount option for remapping reserved characters in
161filenames (also allow recognizing files with created by SFU which have any
Steve French737b7582005-04-28 22:41:06 -0700162of these seven reserved characters, except backslash, to be recognized).
Steve French848f3fc2005-04-28 22:41:07 -0700163Fix invalid transact2 message (we were sometimes trying to interpret
Steve French099a58f2005-04-28 22:41:07 -0700164oplock breaks as SMB responses). Add ioctl for checking that the
165current uid matches the uid of the mounter (needed by umount.cifs).
166Reduce the number of large buffer allocations in cifs response processing
167(significantly reduces memory pressure under heavy stress with multiple
168processes accessing the same server at the same time).
Steve Frenchf654bac2005-04-28 22:41:04 -0700169
170Version 1.31
171------------
Linus Torvalds1da177e2005-04-16 15:20:36 -0700172Fix updates of DOS attributes and time fields so that files on NT4 servers
173do not get marked delete on close. Display sizes of cifs buffer pools in
174cifs stats. Fix oops in unmount when cifsd thread being killed by
175shutdown. Add generic readv/writev and aio support. Report inode numbers
176consistently in readdir and lookup (when serverino mount option is
177specified use the inode number that the server reports - for both lookup
178and readdir, otherwise by default the locally generated inode number is used
179for inodes created in either path since servers are not always able to
180provide unique inode numbers when exporting multiple volumes from under one
181sharename).
182
183Version 1.30
184------------
185Allow new nouser_xattr mount parm to disable xattr support for user namespace.
186Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
187(mostly affects NT4 servers) by retry with handle based network operation.
188Add new POSIX Query FS Info for returning statfs info more accurately.
189Handle passwords with multiple commas in them.
190
191Version 1.29
192------------
193Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
194Fix capabilities flags for large readx so as to allow reads larger than 64K.
195
196Version 1.28
197------------
198Add module init parm for large SMB buffer size (to allow it to be changed
199from its default of 16K) which is especially useful for large file copy
200when mounting with the directio mount option. Fix oops after
201returning from mount when experimental ExtendedSecurity enabled and
202SpnegoNegotiated returning invalid error. Fix case to retry better when
203peek returns from 1 to 3 bytes on socket which should have more data.
204Fixed path based calls (such as cifs lookup) to handle path names
205longer than 530 (now can handle PATH_MAX). Fix pass through authentication
206from Samba server to DC (Samba required dummy LM password).
207
208Version 1.27
209------------
210Turn off DNOTIFY (directory change notification support) by default
211(unless built with the experimental flag) to fix hang with KDE
212file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
213waiting on an SMB response) in SendReceive when session dies but
214reconnects quickly from another task. Add module init parms for
215minimum number of large and small network buffers in the buffer pools,
216and for the maximum number of simultaneous requests.
217
218Version 1.26
219------------
220Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
221and other POSIX CIFS compliant servers. Fix error mapping for getfacl
222to EOPNOTSUPP when server does not support posix acls on the wire. Fix
223improperly zeroed buffer in CIFS Unix extensions set times call.
224
225Version 1.25
226------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700227Fix internationalization problem in cifs readdir with filenames that map to
Alexey Dobriyan4de151d2006-03-22 00:13:35 +0100228longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
Linus Torvalds1da177e2005-04-16 15:20:36 -0700229for readdir to netapp servers. Fix search rewind (seek into readdir to return
230non-consecutive entries). Do not do readdir when server negotiates
231buffer size to small to fit filename. Add support for reading POSIX ACLs from
232the server (add also acl and noacl mount options).
233
234Version 1.24
235------------
236Optionally allow using server side inode numbers, rather than client generated
237ones by specifying mount option "serverino" - this is required for some apps
238to work which double check hardlinked files and have persistent inode numbers.
239
240Version 1.23
241------------
242Multiple bigendian fixes. On little endian systems (for reconnect after
243network failure) fix tcp session reconnect code so we do not try first
244to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
245as directories rather than symlinks because we can do follow link on them.
246
247Version 1.22
248------------
249Add config option to enable XATTR (extended attribute) support, mapping
250xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
251minor fixes pointed out by the Stanford SWAT checker (mostly missing
252or out of order NULL pointer checks in little used error paths).
253
254Version 1.21
255------------
256Add new mount parm to control whether mode check (generic_permission) is done
257on the client. If Unix extensions are enabled and the uids on the client
258and server do not match, client permission checks are meaningless on
259server uids that do not exist on the client (this does not affect the
260normal ACL check which occurs on the server). Fix default uid
261on mknod to match create and mkdir. Add optional mount parm to allow
262override of the default uid behavior (in which the server sets the uid
263and gid of newly created files). Normally for network filesystem mounts
264user want the server to set the uid/gid on newly created files (rather than
265using uid of the client processes you would in a local filesystem).
266
267Version 1.20
268------------
269Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
270info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
271(in build_wildcard_path_from_dentry). Fix mknod to pass type field
272(block/char/fifo) properly. Remove spurious mount warning log entry when
273credentials passed as mount argument. Set major/minor device number in
274inode for block and char devices when unix extensions enabled.
275
276Version 1.19
277------------
278Fix /proc/fs/cifs/Stats and DebugData display to handle larger
279amounts of return data. Properly limit requests to MAX_REQ (50
280is the usual maximum active multiplex SMB/CIFS requests per server).
281Do not kill cifsd (and thus hurt the other SMB session) when more than one
282session to the same server (but with different userids) exists and one
283of the two user's smb sessions is being removed while leaving the other.
284Do not loop reconnecting in cifsd demultiplex thread when admin
285kills the thread without going through unmount.
286
287Version 1.18
288------------
289Do not rename hardlinked files (since that should be a noop). Flush
290cached write behind data when reopening a file after session abend,
291except when already in write. Grab per socket sem during reconnect
292to avoid oops in sendmsg if overlapping with reconnect. Do not
293reset cached inode file size on readdir for files open for write on
294client.
295
296
297Version 1.17
298------------
299Update number of blocks in file so du command is happier (in Linux a fake
300blocksize of 512 is required for calculating number of blocks in inode).
301Fix prepare write of partial pages to read in data from server if possible.
302Fix race on tcpStatus field between unmount and reconnection code, causing
303cifsd process sometimes to hang around forever. Improve out of memory
304checks in cifs_filldir
305
306Version 1.16
307------------
308Fix incorrect file size in file handle based setattr on big endian hardware.
309Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
310and closing file structs in writepage/partialpagewrite. Add statistics
311for each mounted share (new menuconfig option). Fix endianness problem in
312volume information displayed in /proc/fs/cifs/DebugData (only affects
313affects big endian architectures). Prevent renames while constructing
314path names for open, mkdir and rmdir.
315
316Version 1.15
317------------
318Change to mempools for alloc smb request buffers and multiplex structs
319to better handle low memory problems (and potential deadlocks).
320
321Version 1.14
322------------
323Fix incomplete listings of large directories on Samba servers when Unix
324extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
325rename deadlock when writing out dirty pages at same time.
326
327Version 1.13
328------------
329Fix open of files in which O_CREATE can cause the mode to change in
330some cases. Fix case in which retry of write overlaps file close.
331Fix PPC64 build error. Reduce excessive stack usage in smb password
332hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
333
334Version 1.12
335------------
336Fixes for large file copy, signal handling, socket retry, buffer
337allocation and low memory situations.
338
339Version 1.11
340------------
341Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
342also now allowing support for specifying client netbiosname. NT4 support added.
343
344Version 1.10
345------------
346Fix reconnection (and certain failed mounts) to properly wake up the
347blocked users thread so it does not seem hung (in some cases was blocked
348until the cifs receive timeout expired). Fix spurious error logging
349to kernel log when application with open network files killed.
350
351Version 1.09
352------------
353Fix /proc/fs module unload warning message (that could be logged

364
365Version 1.07
366------------
367Fix some small memory leaks in some unmount error paths. Fix major leak
368of cache pages in readpages causing multiple read oriented stress

370
371Version 1.06
372------------
373Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
374This allows files that differ only in case and improves performance of file
375creation and file open to such servers. Fix semaphore conflict which causes
376slow delete of open file to Samba (which unfortunately can cause an oplock
377break to self while vfs_unlink held i_sem) which can hang for 20 seconds.

398Fix caching problem when files opened by multiple clients in which
399page cache could contain stale data, and write through did
400not occur often enough while file was still open when read ahead
401(read oplock) not allowed. Treat "sep=" when first mount option
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700402as an override of comma as the default separator between mount
Linus Torvalds1da177e2005-04-16 15:20:36 -0700403options.
404
405Version 1.01

414
415Version 0.99
416------------
417Invalidate local inode cached pages on oplock break and when last file
418instance is closed so that the client does not continue using stale local
419copy rather than later modified server copy of file. Do not reconnect
420when server drops the tcp session prematurely before negotiate
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700421protocol response. Fix oops in reopen_file when dentry freed. Allow
Linus Torvalds1da177e2005-04-16 15:20:36 -0700422the support for CIFS Unix Extensions to be disabled via proc interface.
423
424Version 0.98
425------------
426Fix hang in commit_write during reconnection of open files under heavy load.
427Fix unload_nls oops in a mount failure path. Serialize writes to same socket

429being sent out of signature sequence number order.
430
431Version 0.97
432------------
433Fix byte range locking bug (endian problem) causing bad offset and
434length.
435
436Version 0.96
437------------
438Fix oops (in send_sig) caused by CIFS unmount code trying to

506redundant NTCreate/QPathInfo/close that was sent during file create.
507Enable oplock by default. Enable packet signing by default (needed to
508access many recent Windows servers)
509
510Version 0.83
511------------
512Fix oops when mounting to long server names caused by inverted parms to kmalloc.
513Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
514we will choose a cifs user session (smb uid) that better matches the local
515uid if a) the mount uid does not match the current uid and b) we have another
516session to the same server (ip address) for a different mount which

528NTLM security case. This should help Windows 2003
529network interoperability since it is common for
530packet signing to be required now. Fix statfs (stat -f)
531which recently started returning errors due to
532invalid value (-1 instead of 0) being set in the
533struct kstatfs f_ffiles field.
534

547Fixed various incorrect or misleading smb to posix error code mappings.
548
549Version 0.77
550------------
551Fix display of NTFS DFS junctions to display as symlinks.
552They are the network equivalent. Fix oops in
553cifs_partialpagewrite caused by missing spinlock protection

596
597Version 0.69
598------------
599Fix buffer overrun in readdir which caused intermittent kernel oopses.
600Fix writepage code to release kmap on write data. Allow "-ip=" new
601mount option to be passed in on parameter distinct from the first part
602(server name portion of) the UNC name. Allow override of the
603tcp port of the target server via new mount option "-port="
604
605Version 0.68
606------------
607Fix search handle leak on rewind. Fix setuid and gid so that they are
608reflected in the local inode immediately. Cleanup of whitespace
609to make 2.4 and 2.5 versions more consistent.
610
611
612Version 0.67
613------------
614Fix signal sending so that captive thread (cifsd) exits on umount
615(which was causing the warning in kmem_cache_free of the request buffers
616at rmmod time). This had broken as a sideeffect of the recent global
617kernel change to daemonize. Fix memory leak in readdir code which
618showed up in "ls -R" (and applications that did search rewinding).
619
620Version 0.66
621------------

637common error paths. Add generic sendfile support.
638
639Version 0.63
640------------
641Fix memory leak in AllocMidQEntry.
642Finish reconnection logic, so connection with server can be dropped
643(or server rebooted) and the cifs client will reconnect.
644
645Version 0.62
646------------
647Fix temporary socket leak when bad userid or password specified
648(or other SMBSessSetup failure). Increase maximum buffer size to slightly

651
652Version 0.61
653------------
654Fix oops when username not passed in on mount. Extensive fixes and improvements
655to error logging (strip redundant newlines, change debug macros to ensure newline
656passed in and to be more consistent). Fix writepage wrong file handle problem,
657a readonly file handle could be incorrectly used to attempt to write out
658file updates through the page cache to multiply open files. This could cause
659the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
660shares to the same Windows server when using different usernames
661(doing this to Samba servers worked but Windows was rejecting it) - now it is
662possible to use different userids when connecting to the same server from a
663Linux client. Fix oops when treeDisconnect called during unmount on
664previously freed socket.
665
666Version 0.60

678Changed read and write to go through pagecache. Added additional address space operations.
679Memory mapped operations now working.
680
681Version 0.57
682------------
683Added writepage code for additional memory mapping support. Fixed leak in xids causing
684the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
685every stat call. Additional formatting cleanup.

759
760Version 0.41
761------------
762Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700763files now return the correct number of links on fstat as they are repeatedly linked and unlinked.

791
792Version 0.34
793------------
794Fixed dentry caching bug, misc. cleanup
795
796Version 0.33
797------------
798Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
799on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.

807
808Version 0.31
809------------
8101) Fixed lockrange to be correct (it was one byte too short)
811
8122) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
813show range as locked when there is a conflict with an existing lock.
814
8153) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
816in most cases. Eventually will offer optional ability to query server for the correct perms.
817
8183) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
819but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
820session)
821
8224) Fixed error logging of valid mount options
823
8245) Removed logging of password field.
825
8266) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
827and cleaned them up and made them more consistent with other cifs functions.
828
8297) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700830(with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
Linus Torvalds1da177e2005-04-16 15:20:36 -0700831nor is the symlink support using the Unix extensions
