2------------
Steve French84afc292005-12-02 13:32:45 -08003Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
4of readpages by eliminating one extra memcpy.

Steve French23e7dd72005-10-20 13:44:56 -07006Version 1.39
7------------
Steve French3abb9272005-11-28 08:16:13 -08008Defer close of a file handle slightly if pending writes depend on that handle
Steve French23e7dd72005-10-20 13:44:56 -07009(this reduces the EBADF bad file handle errors that can be logged under heavy
Steve French3c50c612005-11-10 17:31:33 -080010stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
Steve French3abb9272005-11-28 08:16:13 -080011Fix SFU style symlinks and mknod needed for servers which do not support the
12CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
13dentries so files that the client sees as deleted but that later get created
Steve French6473a552005-11-29 20:20:10 -080014on the server will be recognized. Add client side permission check on setattr.
Steve French83451872005-12-01 17:12:59 -080015Timeout stuck requests better (where server has never responded or sent corrupt
16responses)
Steve French23e7dd72005-10-20 13:44:56 -070017
Steve French190fdeb2005-10-10 11:48:26 -070018Version 1.38
19------------
20Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
21to be smaller at first (but increasing) so large write performance performance
22over GigE is better. Do not hang thread on illegal byte range lock response
23from Windows (Windows can send an RFC1001 size which does not match smb size) by
24allowing an SMBs TCP length to be up to a few bytes longer than it should be.
25wsize and rsize can now be larger than negotiated buffer size if server
26supports large readx/writex, even when directio mount flag not specified.
27Write size will in many cases now be 16K instead of 4K which greatly helps
Steve French4ca9c192005-10-10 19:52:13 -070028file copy performance on lightly loaded networks. Fix oops in dnotify
Steve French1047abc2005-10-11 19:58:06 -070029when experimental config flag enabled. Make cifsFYI more granular.
Steve French190fdeb2005-10-10 11:48:26 -070030
Steve Frencheafe8702005-09-15 21:47:30 -070031Version 1.37
32------------
33Fix readdir caching when unlink removes file in current search buffer,
34and this is followed by a rewind search to just before the deleted entry.
Steve Frenche30dcf32005-09-20 20:49:16 -070035Do not attempt to set ctime unless atime and/or mtime change requested
Steve French20962432005-09-21 22:05:57 -070036(most servers throw it away anyway). Fix length check of received smbs
Steve French70ca7342005-09-22 16:32:06 -070037to be more accurate. Fix big endian problem with mapchars mount option,
38and with a field returned by statfs.
Steve Frencheafe8702005-09-15 21:47:30 -070039
Steve Frenchc46fa8a2005-08-18 20:49:57 -070040Version 1.36
41------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -070042Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
Steve French6b8edfe2005-08-23 20:26:03 -070043For these older servers, add option for passing netbios name of server in
Steve French16abbec2005-08-30 13:10:14 -070044on mount (servernetbiosname). Add suspend support for power management, to
45avoid cifsd thread preventing software suspend from working.
Steve Frenchc46fa8a2005-08-18 20:49:57 -070046Add mount option for disabling the default behavior of sending byte range lock
47requests to the server (necessary for certain applications which break with
48mandatory lock behavior such as Evolution), and also mount option for
49requesting case insensitive matching for path based requests (requesting
50case sensitive is the default).
51
Steve Frenchf4cfd692005-07-14 18:29:02 -050052Version 1.35
53------------
54Add writepage performance improvements. Fix path name conversions
55for long filenames on mounts which were done with "mapchars" mount option
Steve Frencha10faeb22005-08-22 21:38:31 -070056specified. Ensure multiplex ids do not collide. Fix case in which
57rmmod can oops if done soon after last unmount. Fix truncated
58search (readdir) output when resume filename was a long filename.
59Fix filename conversion when mapchars mount option was specified and
60filename was a long filename.
Steve Frenchf4cfd692005-07-14 18:29:02 -050061
Steve French11aa0142005-04-28 22:41:10 -070062Version 1.34
63------------
64Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
Steve French31ca3bc2005-04-28 22:41:11 -070065Do not oops if root user kills cifs oplock kernel thread or
66kills the cifsd thread (NB: killing the cifs kernel threads is not
67recommended, unmount and rmmod cifs will kill them when they are
Steve French68575472005-04-30 11:10:57 -070068no longer needed). Fix readdir to ASCII servers (ie older servers
Steve Frenchc0c3e8e2005-08-24 14:01:13 -070069which do not support Unicode) and also require asterisk.
Steve French3079ca62005-06-09 14:44:07 -070070Fix out of memory case in which data could be written one page
71off in the page cache.
Steve French11aa0142005-04-28 22:41:10 -070072
Steve French966ca922005-04-28 22:41:08 -070073Version 1.33
74------------
75Fix caching problem, in which readdir of directory containing a file
76which was cached could cause the file's time stamp to be updated
77without invalidating the readahead data (so we could get stale
78file data on the client for that file even as the server copy changed).
Steve Frenchcd634992005-04-28 22:41:10 -070079Cleanup response processing so cifsd can not loop when abnormally
80terminated.
Steve French966ca922005-04-28 22:41:08 -070081
82
Steve Frenchf654bac2005-04-28 22:41:04 -070083Version 1.32
Linus Torvalds1da177e2005-04-16 15:20:36 -070084------------
85Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
86transact response for an SMB request and search entry split across two frames.
Steve Frenchf654bac2005-04-28 22:41:04 -070087Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
88as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
89unless server explicitly claims to support them in CIFS Unix extensions
Steve Frenchad009ac2005-04-28 22:41:05 -070090POSIX ACL capability bit. Fix packet signing when multiuser mounting with
Steve Frenchcbe04762005-04-28 22:41:05 -070091different users from the same client to the same server. Fix oops in
Steve French6a0b4822005-04-28 22:41:05 -070092cifs_close. Add mount option for remapping reserved characters in
93filenames (also allow recognizing files with created by SFU which have any
Steve French737b7582005-04-28 22:41:06 -070094of these seven reserved characters, except backslash, to be recognized).
Steve French848f3fc2005-04-28 22:41:07 -070095Fix invalid transact2 message (we were sometimes trying to interpret
Steve French099a58f2005-04-28 22:41:07 -070096oplock breaks as SMB responses). Add ioctl for checking that the
97current uid matches the uid of the mounter (needed by umount.cifs).
98Reduce the number of large buffer allocations in cifs response processing
99(significantly reduces memory pressure under heavy stress with multiple
100processes accessing the same server at the same time).
Steve Frenchf654bac2005-04-28 22:41:04 -0700101
102Version 1.31
103------------
Linus Torvalds1da177e2005-04-16 15:20:36 -0700104Fix updates of DOS attributes and time fields so that files on NT4 servers
105do not get marked delete on close. Display sizes of cifs buffer pools in
106cifs stats. Fix oops in unmount when cifsd thread being killed by
107shutdown. Add generic readv/writev and aio support. Report inode numbers
108consistently in readdir and lookup (when serverino mount option is
109specified use the inode number that the server reports - for both lookup
110and readdir, otherwise by default the locally generated inode number is used
111for inodes created in either path since servers are not always able to
112provide unique inode numbers when exporting multiple volumes from under one
113sharename).
114
115Version 1.30
116------------
117Allow new nouser_xattr mount parm to disable xattr support for user namespace.
118Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
119(mostly affects NT4 servers) by retry with handle based network operation.
120Add new POSIX Query FS Info for returning statfs info more accurately.
121Handle passwords with multiple commas in them.
122
123Version 1.29
124------------
125Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
126Fix capabilities flags for large readx so as to allow reads larger than 64K.
127
128Version 1.28
129------------
130Add module init parm for large SMB buffer size (to allow it to be changed
131from its default of 16K) which is especially useful for large file copy
132when mounting with the directio mount option. Fix oops after
133returning from mount when experimental ExtendedSecurity enabled and
134SpnegoNegotiated returning invalid error. Fix case to retry better when
135peek returns from 1 to 3 bytes on socket which should have more data.
136Fixed path based calls (such as cifs lookup) to handle path names
137longer than 530 (now can handle PATH_MAX). Fix pass through authentication
138from Samba server to DC (Samba required dummy LM password).
139
140Version 1.27
141------------
142Turn off DNOTIFY (directory change notification support) by default
143(unless built with the experimental flag) to fix hang with KDE
144file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
145waiting on an SMB response) in SendReceive when session dies but
146reconnects quickly from another task. Add module init parms for
147minimum number of large and small network buffers in the buffer pools,
148and for the maximum number of simultaneous requests.
149
150Version 1.26
151------------
152Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
153and other POSIX CIFS compliant servers. Fix error mapping for getfacl
154to EOPNOTSUPP when server does not support posix acls on the wire. Fix
155improperly zeroed buffer in CIFS Unix extensions set times call.
156
157Version 1.25
158------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700159Fix internationalization problem in cifs readdir with filenames that map to
Linus Torvalds1da177e2005-04-16 15:20:36 -0700160longer UTF8 strings than the string on the wire was in Unicode. Add workaround
161for readdir to netapp servers. Fix search rewind (seek into readdir to return
162non-consecutive entries). Do not do readdir when server negotiates
163buffer size to small to fit filename. Add support for reading POSIX ACLs from
164the server (add also acl and noacl mount options).
165
166Version 1.24
167------------
168Optionally allow using server side inode numbers, rather than client generated
169ones by specifying mount option "serverino" - this is required for some apps
170to work which double check hardlinked files and have persistent inode numbers.
171
172Version 1.23
173------------
174Multiple bigendian fixes. On little endian systems (for reconnect after
175network failure) fix tcp session reconnect code so we do not try first
176to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
177as directories rather than symlinks because we can do follow link on them.
178
179Version 1.22
180------------
181Add config option to enable XATTR (extended attribute) support, mapping
182xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
183minor fixes pointed out by the Stanford SWAT checker (mostly missing
184or out of order NULL pointer checks in little used error paths).
185
186Version 1.21
187------------
188Add new mount parm to control whether mode check (generic_permission) is done
189on the client. If Unix extensions are enabled and the uids on the client
190and server do not match, client permission checks are meaningless on
191server uids that do not exist on the client (this does not affect the
192normal ACL check which occurs on the server). Fix default uid
193on mknod to match create and mkdir. Add optional mount parm to allow
194override of the default uid behavior (in which the server sets the uid
195and gid of newly created files). Normally for network filesystem mounts
196user want the server to set the uid/gid on newly created files (rather than
197using uid of the client processes you would in a local filesystem).
198
199Version 1.20
200------------
201Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
202info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
203(in build_wildcard_path_from_dentry). Fix mknod to pass type field
204(block/char/fifo) properly. Remove spurious mount warning log entry when
205credentials passed as mount argument. Set major/minor device number in
206inode for block and char devices when unix extensions enabled.
207
208Version 1.19
209------------
210Fix /proc/fs/cifs/Stats and DebugData display to handle larger
211amounts of return data. Properly limit requests to MAX_REQ (50
212is the usual maximum active multiplex SMB/CIFS requests per server).
213Do not kill cifsd (and thus hurt the other SMB session) when more than one
214session to the same server (but with different userids) exists and one
215of the two user's smb sessions is being removed while leaving the other.
216Do not loop reconnecting in cifsd demultiplex thread when admin
217kills the thread without going through unmount.
218
219Version 1.18
220------------
221Do not rename hardlinked files (since that should be a noop). Flush
222cached write behind data when reopening a file after session abend,
223except when already in write. Grab per socket sem during reconnect
224to avoid oops in sendmsg if overlapping with reconnect. Do not
225reset cached inode file size on readdir for files open for write on
226client.
227
228
229Version 1.17
230------------
231Update number of blocks in file so du command is happier (in Linux a fake
232blocksize of 512 is required for calculating number of blocks in inode).
233Fix prepare write of partial pages to read in data from server if possible.
234Fix race on tcpStatus field between unmount and reconnection code, causing
235cifsd process sometimes to hang around forever. Improve out of memory
236checks in cifs_filldir
237
238Version 1.16
239------------
240Fix incorrect file size in file handle based setattr on big endian hardware.
241Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
242and closing file structs in writepage/partialpagewrite. Add statistics
243for each mounted share (new menuconfig option). Fix endianness problem in
244volume information displayed in /proc/fs/cifs/DebugData (only affects
245affects big endian architectures). Prevent renames while constructing
246path names for open, mkdir and rmdir.
247
248Version 1.15
249------------
250Change to mempools for alloc smb request buffers and multiplex structs
251to better handle low memory problems (and potential deadlocks).
252
253Version 1.14
254------------
255Fix incomplete listings of large directories on Samba servers when Unix
256extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
257rename deadlock when writing out dirty pages at same time.
258
259Version 1.13
260------------
261Fix open of files in which O_CREATE can cause the mode to change in
262some cases. Fix case in which retry of write overlaps file close.
263Fix PPC64 build error. Reduce excessive stack usage in smb password
264hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
265
266Version 1.12
267------------
268Fixes for large file copy, signal handling, socket retry, buffer
269allocation and low memory situations.
270
271Version 1.11
272------------
273Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
274also now allowing support for specifying client netbiosname. NT4 support added.
275
276Version 1.10
277------------
278Fix reconnection (and certain failed mounts) to properly wake up the
279blocked users thread so it does not seem hung (in some cases was blocked
280until the cifs receive timeout expired). Fix spurious error logging
281to kernel log when application with open network files killed.
282
283Version 1.09
284------------
285Fix /proc/fs module unload warning message (that could be logged
286to the kernel log). Fix intermittent failure in connectathon
287test7 (hardlink count not immediately refreshed in case in which
288inode metadata can be incorrectly kept cached when time near zero)
289
290Version 1.08
291------------
292Allow file_mode and dir_mode (specified at mount time) to be enforced
293locally (the server already enforced its own ACLs too) for servers
294that do not report the correct mode (do not support the
295CIFS Unix Extensions).
296
297Version 1.07
298------------
299Fix some small memory leaks in some unmount error paths. Fix major leak
300of cache pages in readpages causing multiple read oriented stress
301testcases (including fsx, and even large file copy) to fail over time.
302
303Version 1.06
304------------
305Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
306This allows files that differ only in case and improves performance of file
307creation and file open to such servers. Fix semaphore conflict which causes
308slow delete of open file to Samba (which unfortunately can cause an oplock
309break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
310
311Version 1.05
312------------
313fixes to cifs_readpages for fsx test case
314
315Version 1.04
316------------
317Fix caching data integrity bug when extending file size especially when no
318oplock on file. Fix spurious logging of valid already parsed mount options
319that are parsed outside of the cifs vfs such as nosuid.
320
321
322Version 1.03
323------------
324Connect to server when port number override not specified, and tcp port
325unitialized. Reset search to restart at correct file when kernel routine
326filldir returns error during large directory searches (readdir).
327
328Version 1.02
329------------
330Fix caching problem when files opened by multiple clients in which
331page cache could contain stale data, and write through did
332not occur often enough while file was still open when read ahead
333(read oplock) not allowed. Treat "sep=" when first mount option
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700334as an override of comma as the default separator between mount
Linus Torvalds1da177e2005-04-16 15:20:36 -0700335options.
336
337Version 1.01
338------------
339Allow passwords longer than 16 bytes. Allow null password string.
340
341Version 1.00
342------------
343Gracefully clean up failed mounts when attempting to mount to servers such as
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700344Windows 98 that terminate tcp sessions during protocol negotiation. Handle
Linus Torvalds1da177e2005-04-16 15:20:36 -0700345embedded commas in mount parsing of passwords.
346
347Version 0.99
348------------
349Invalidate local inode cached pages on oplock break and when last file
350instance is closed so that the client does not continue using stale local
351copy rather than later modified server copy of file. Do not reconnect
352when server drops the tcp session prematurely before negotiate
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700353protocol response. Fix oops in reopen_file when dentry freed. Allow
Linus Torvalds1da177e2005-04-16 15:20:36 -0700354the support for CIFS Unix Extensions to be disabled via proc interface.
355
356Version 0.98
357------------
358Fix hang in commit_write during reconnection of open files under heavy load.
359Fix unload_nls oops in a mount failure path. Serialize writes to same socket
360which also fixes any possible races when cifs signatures are enabled in SMBs
361being sent out of signature sequence number order.
362
363Version 0.97
364------------
365Fix byte range locking bug (endian problem) causing bad offset and
366length.
367
368Version 0.96
369------------
370Fix oops (in send_sig) caused by CIFS unmount code trying to
371wake up the demultiplex thread after it had exited. Do not log
372error on harmless oplock release of closed handle.
373
374Version 0.95
375------------
376Fix unsafe global variable usage and password hash failure on gcc 3.3.1
377Fix problem reconnecting secondary mounts to same server after session
378failure. Fix invalid dentry - race in mkdir when directory gets created
379by another client between the lookup and mkdir.
380
381Version 0.94
382------------
383Fix to list processing in reopen_files. Fix reconnection when server hung
384but tcpip session still alive. Set proper timeout on socket read.
385
386Version 0.93
387------------
388Add missing mount options including iocharset. SMP fixes in write and open.
389Fix errors in reconnecting after TCP session failure. Fix module unloading
390of default nls codepage
391
392Version 0.92
393------------
394Active smb transactions should never go negative (fix double FreeXid). Fix

428Fix oops on empty file readahead. Fix for file size handling for locally cached files.
429
430Version 0.85
431------------
432Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files
433during auto reconnection to server after server recovered from failure.
434
435Version 0.84
436------------
437Finish support for Linux 2.5 open/create changes, which removes the
438redundant NTCreate/QPathInfo/close that was sent during file create.
439Enable oplock by default. Enable packet signing by default (needed to
440access many recent Windows servers)
441
442Version 0.83
443------------
444Fix oops when mounting to long server names caused by inverted parms to kmalloc.
445Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
446we will choose a cifs user session (smb uid) that better matches the local
447uid if a) the mount uid does not match the current uid and b) we have another
448session to the same server (ip address) for a different mount which
449matches the current local uid.
450

460NTLM security case. This should help Windows 2003
461network interoperability since it is common for
462packet signing to be required now. Fix statfs (stat -f)
463which recently started returning errors due to

480
481Version 0.77
482------------
483Fix display of NTFS DFS junctions to display as symlinks.
484They are the network equivalent. Fix oops in
485cifs_partialpagewrite caused by missing spinlock protection
486of openfile linked list. Allow writebehind caching errors to
487be returned to the application at file close.
488
489Version 0.76
490------------
491Clean up options displayed in /proc/mounts by show_options to
492be more consistent with other filesystems.

497presence or absence of read only dos attribute in mode
498bits for servers that do not support CIFS Unix extensions.
499Fix shortened results on readdir of large directories to
500servers supporting CIFS Unix extensions (caused by
501incorrect resume key).
502
503Version 0.74

515allows disabling caching of attribute information for
516lookups.
517
518Version 0.71
519------------
520Add more oplock handling (distributed caching code). Remove
521dead code. Remove excessive stack space utilization from
522symlink routines.
523
524Version 0.70
525------------
526Fix oops in get dfs referral (triggered when null path sent in to
527mount). Add support for overriding rsize at mount time.
528
529Version 0.69
530------------
531Fix buffer overrun in readdir which caused intermittent kernel oopses.
532Fix writepage code to release kmap on write data. Allow "-ip=" new
533mount option to be passed in on parameter distinct from the first part
534(server name portion of) the UNC name. Allow override of the
535tcp port of the target server via new mount option "-port="
536
537Version 0.68
538------------
539Fix search handle leak on rewind. Fix setuid and gid so that they are
540reflected in the local inode immediately. Cleanup of whitespace
541to make 2.4 and 2.5 versions more consistent.
542
543
544Version 0.67
545------------
546Fix signal sending so that captive thread (cifsd) exits on umount
547(which was causing the warning in kmem_cache_free of the request buffers
548at rmmod time). This had broken as a sideeffect of the recent global
549kernel change to daemonize. Fix memory leak in readdir code which
550showed up in "ls -R" (and applications that did search rewinding).
551
552Version 0.66
553------------
554Reconnect tids and fids after session reconnection (still do not
555reconnect byte range locks though). Fix problem caching
556lookup information for directory inodes, improving performance,
557especially in deep directory trees. Fix various build warnings.
558
559Version 0.65
560------------

563was interrupted by a signal.
564
565Version 0.64
566------------
567Fix data corruption (in partial page after truncate) that caused fsx to
568fail to Windows servers. Cleaned up some extraneous error logging in
569common error paths. Add generic sendfile support.
570
571Version 0.63
572------------
573Fix memory leak in AllocMidQEntry.
574Finish reconnection logic, so connection with server can be dropped
575(or server rebooted) and the cifs client will reconnect.
576
577Version 0.62
578------------
579Fix temporary socket leak when bad userid or password specified
580(or other SMBSessSetup failure). Increase maximum buffer size to slightly
581over 16K to allow negotiation of up to Samba and Windows server default read
582sizes. Add support for readpages
583
584Version 0.61
585------------
586Fix oops when username not passed in on mount. Extensive fixes and improvements
587to error logging (strip redundant newlines, change debug macros to ensure newline
588passed in and to be more consistent). Fix writepage wrong file handle problem,
589a readonly file handle could be incorrectly used to attempt to write out
590file updates through the page cache to multiply open files. This could cause
591the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
592shares to the same Windows server when using different usernames
593(doing this to Samba servers worked but Windows was rejecting it) - now it is
594possible to use different userids when connecting to the same server from a
595Linux client. Fix oops when treeDisconnect called during unmount on
596previously freed socket.
597
598Version 0.60

606requirement). Add readlink support for Windows junction points (directory symlinks).
607
608Version 0.58
609------------
610Changed read and write to go through pagecache. Added additional address space operations.
611Memory mapped operations now working.
612
613Version 0.57
614------------
615Added writepage code for additional memory mapping support. Fixed leak in xids causing
616the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
617every stat call. Additional formatting cleanup.
618
619Version 0.56
620------------
621Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
622

633buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
634
635Version 0.53
636------------

691
692Version 0.41
693------------
694Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700695files now return the correct number of links on fstat as they are repeatedly linked and unlinked.
Linus Torvalds1da177e2005-04-16 15:20:36 -0700696
697Version 0.40
698------------
699Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate

723
724Version 0.34
725------------
726Fixed dentry caching bug, misc. cleanup
727
728Version 0.33
729------------
730Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
731on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
732Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
733
734Version 0.32

739
740Version 0.31
741------------
7421) Fixed lockrange to be correct (it was one byte too short)
743
7442) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
745show range as locked when there is a conflict with an existing lock.
746
7473) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
748in most cases. Eventually will offer optional ability to query server for the correct perms.
749
7503) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
751but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
752session)
753
7544) Fixed error logging of valid mount options
755
7565) Removed logging of password field.
757
7586) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
759and cleaned them up and made them more consistent with other cifs functions.
760
7617) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700762(with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
Linus Torvalds1da177e2005-04-16 15:20:36 -0700763nor is the symlink support using the Unix extensions
