3Fix oops in list_del during mount caused by unaligned string.
4
Steve French2fe87f02006-09-21 07:02:52 +00005Version 1.46
6------------
7Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
Steve French4b952a92006-10-30 21:46:13 +00008Allow null user to be specified on mount ("username="). Do not return
9EINVAL on readdir when filldir fails due to overwritten blocksize
Steve French8e87d4d2006-11-02 03:45:24 +000010(fixes FC problem). Return error in rename 2nd attempt retry (ie report
11if rename by handle also fails, after rename by path fails, we were
Steve French33ec32f2006-12-08 04:14:28 +000012not reporting whether the retry worked or not). Fix NTLMv2 to
13work to Windows servers (mount with option "sec=ntlmv2").

Steve French3a5ff612006-07-14 22:37:11 +000015Version 1.45
16------------
17Do not time out lockw calls when using posix extensions. Do not
18time out requests if server still responding reasonably fast
Steve Frenche466e482006-08-15 13:07:18 +000019on requests on other threads. Improve POSIX locking emulation,
20(lock cancel now works, and unlock of merged range works even
21to Windows servers now). Fix oops on mount to lanman servers
Steve Frenchea4c07d2006-08-16 19:44:25 +000022(win9x, os/2 etc.) when null password. Do not send listxattr
Steve French2fe87f02006-09-21 07:02:52 +000023(SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
24problem (instantiate inodes/dentries in right order for readdir).
Steve French3a5ff612006-07-14 22:37:11 +000025
Steve French39798772006-05-31 22:40:51 +000026Version 1.44
27------------
28Rewritten sessionsetup support, including support for legacy SMB
29session setup needed for OS/2 and older servers such as Windows 95 and 98.
Steve French5bafd762006-06-07 00:18:43 +000030Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
31so we can do search (ls etc.) to OS/2. Do not send NTCreateX
32or recent levels of FindFirst unless server says it supports NT SMBs
Steve French1717ffc2006-06-08 05:41:32 +000033(instead use legacy equivalents from LANMAN dialect). Fix to allow
34NTLMv2 authentication support (now can use stronger password hashing
Steve French750d1152006-06-27 06:28:30 +000035on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
36Allow override of global cifs security flags on mount via "sec=" option(s).
Steve French39798772006-05-31 22:40:51 +000037
Steve Frenchfc94cdb2006-05-30 18:03:32 +000038Version 1.43
39------------
40POSIX locking to servers which support CIFS POSIX Extensions
Steve Frencha878fb22006-05-30 18:04:19 +000041(disabled by default controlled by proc/fs/cifs/Experimental).
42Handle conversion of long share names (especially Asian languages)
Steve French26a21b92006-05-31 18:05:34 +000043to Unicode during mount. Fix memory leak in sess struct on reconnect.
44Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
45cifs open which helps rare case when setpathinfo fails or server does
46not support it.
Steve Frenchfc94cdb2006-05-30 18:03:32 +000047
Steve French13298de2006-03-03 10:45:19 +000048Version 1.42
49------------
50Fix slow oplock break when mounted to different servers at the same time and
Steve French60808232006-04-22 15:53:05 +000051the tids match and we try to find matching fid on wrong server. Fix read
52looping when signing required by server (2.6.16 kernel only). Fix readdir
53vs. rename race which could cause each to hang. Return . and .. even
54if server does not. Allow searches to skip first three entries and
55begin at any location. Fix oops in find_writeable_file.
Steve French13298de2006-03-03 10:45:19 +000056
Steve French12b3b8f2006-02-09 21:12:47 +000057Version 1.41
58------------
59Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
60configure stronger authentication. Fix sfu symlinks so they can
Steve French184ed212006-02-24 06:15:11 +000061be followed (not just recognized). Fix wraparound of bcc on
62read responses when buffer size over 64K and also fix wrap of
63max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
64cifs_user_read and cifs_readpages (when EAGAIN on send of smb
Steve French08547b02006-02-28 22:39:25 +000065on socket is returned over and over). Add POSIX (advisory) byte range
66locking support (requires server with newest CIFS UNIX Extensions
Steve French083d3a22006-03-03 09:53:36 +000067to the protocol implemented). Slow down negprot slightly in port 139
68RFC1001 case to give session_init time on buggy servers.
Steve French12b3b8f2006-02-09 21:12:47 +000069
Steve French83451872005-12-01 17:12:59 -080070Version 1.40
71------------
Steve French84afc292005-12-02 13:32:45 -080072Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
Steve French0a4b92c2006-01-12 15:44:21 -080073of readpages by eliminating one extra memcpy. Allow update of file size
74from remote server even if file is open for write as long as mount is
Steve Frencheeac8042006-01-13 21:34:58 -080075directio. Recognize share mode security and send NTLM encrypted password
76on tree connect if share mode negotiated.
Steve French83451872005-12-01 17:12:59 -080077
Steve French23e7dd72005-10-20 13:44:56 -070078Version 1.39
79------------
Steve French3abb9272005-11-28 08:16:13 -080080Defer close of a file handle slightly if pending writes depend on that handle
Steve French23e7dd72005-10-20 13:44:56 -070081(this reduces the EBADF bad file handle errors that can be logged under heavy
Steve French3c50c612005-11-10 17:31:33 -080082stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
Steve French3abb9272005-11-28 08:16:13 -080083Fix SFU style symlinks and mknod needed for servers which do not support the
84CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
85dentries so files that the client sees as deleted but that later get created
Steve French6473a552005-11-29 20:20:10 -080086on the server will be recognized. Add client side permission check on setattr.
Steve French83451872005-12-01 17:12:59 -080087Timeout stuck requests better (where server has never responded or sent corrupt
88responses)
Steve French23e7dd72005-10-20 13:44:56 -070089
Steve French190fdeb2005-10-10 11:48:26 -070090Version 1.38
91------------
92Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
93to be smaller at first (but increasing) so large write performance performance
94over GigE is better. Do not hang thread on illegal byte range lock response
95from Windows (Windows can send an RFC1001 size which does not match smb size) by
96allowing an SMBs TCP length to be up to a few bytes longer than it should be.
97wsize and rsize can now be larger than negotiated buffer size if server
98supports large readx/writex, even when directio mount flag not specified.
99Write size will in many cases now be 16K instead of 4K which greatly helps
Steve French4ca9c192005-10-10 19:52:13 -0700100file copy performance on lightly loaded networks. Fix oops in dnotify
Steve French1047abc2005-10-11 19:58:06 -0700101when experimental config flag enabled. Make cifsFYI more granular.
Steve French190fdeb2005-10-10 11:48:26 -0700102
Steve Frencheafe8702005-09-15 21:47:30 -0700103Version 1.37
104------------
105Fix readdir caching when unlink removes file in current search buffer,
106and this is followed by a rewind search to just before the deleted entry.
Steve Frenche30dcf32005-09-20 20:49:16 -0700107Do not attempt to set ctime unless atime and/or mtime change requested
Steve French20962432005-09-21 22:05:57 -0700108(most servers throw it away anyway). Fix length check of received smbs
Steve French70ca7342005-09-22 16:32:06 -0700109to be more accurate. Fix big endian problem with mapchars mount option,
110and with a field returned by statfs.
Steve Frencheafe8702005-09-15 21:47:30 -0700111
Steve Frenchc46fa8a2005-08-18 20:49:57 -0700112Version 1.36
113------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700114Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
Steve French6b8edfe2005-08-23 20:26:03 -0700115For these older servers, add option for passing netbios name of server in
Steve French16abbec2005-08-30 13:10:14 -0700116on mount (servernetbiosname). Add suspend support for power management, to
117avoid cifsd thread preventing software suspend from working.
Steve Frenchc46fa8a2005-08-18 20:49:57 -0700118Add mount option for disabling the default behavior of sending byte range lock
119requests to the server (necessary for certain applications which break with
120mandatory lock behavior such as Evolution), and also mount option for
121requesting case insensitive matching for path based requests (requesting
122case sensitive is the default).
123
Steve Frenchf4cfd692005-07-14 18:29:02 -0500124Version 1.35
125------------
126Add writepage performance improvements. Fix path name conversions
127for long filenames on mounts which were done with "mapchars" mount option
Steve Frencha10faeb22005-08-22 21:38:31 -0700128specified. Ensure multiplex ids do not collide. Fix case in which
129rmmod can oops if done soon after last unmount. Fix truncated
130search (readdir) output when resume filename was a long filename.
131Fix filename conversion when mapchars mount option was specified and
132filename was a long filename.
Steve Frenchf4cfd692005-07-14 18:29:02 -0500133
Steve French11aa0142005-04-28 22:41:10 -0700134Version 1.34
135------------
136Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
Steve French31ca3bc2005-04-28 22:41:11 -0700137Do not oops if root user kills cifs oplock kernel thread or
138kills the cifsd thread (NB: killing the cifs kernel threads is not
139recommended, unmount and rmmod cifs will kill them when they are
Steve French68575472005-04-30 11:10:57 -0700140no longer needed). Fix readdir to ASCII servers (ie older servers
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700141which do not support Unicode) and also require asterisk.
Steve French3079ca62005-06-09 14:44:07 -0700142Fix out of memory case in which data could be written one page
143off in the page cache.
Steve French11aa0142005-04-28 22:41:10 -0700144
Steve French966ca922005-04-28 22:41:08 -0700145Version 1.33
146------------
147Fix caching problem, in which readdir of directory containing a file
148which was cached could cause the file's time stamp to be updated
149without invalidating the readahead data (so we could get stale
150file data on the client for that file even as the server copy changed).
Steve Frenchcd634992005-04-28 22:41:10 -0700151Cleanup response processing so cifsd can not loop when abnormally
152terminated.
Steve French966ca922005-04-28 22:41:08 -0700153
154
Steve Frenchf654bac2005-04-28 22:41:04 -0700155Version 1.32
Linus Torvalds1da177e2005-04-16 15:20:36 -0700156------------
157Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
158transact response for an SMB request and search entry split across two frames.
Steve Frenchf654bac2005-04-28 22:41:04 -0700159Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
160as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
161unless server explicitly claims to support them in CIFS Unix extensions
Steve Frenchad009ac2005-04-28 22:41:05 -0700162POSIX ACL capability bit. Fix packet signing when multiuser mounting with
Steve Frenchcbe04762005-04-28 22:41:05 -0700163different users from the same client to the same server. Fix oops in
Steve French6a0b4822005-04-28 22:41:05 -0700164cifs_close. Add mount option for remapping reserved characters in
165filenames (also allow recognizing files with created by SFU which have any
Steve French737b7582005-04-28 22:41:06 -0700166of these seven reserved characters, except backslash, to be recognized).
Steve French848f3fc2005-04-28 22:41:07 -0700167Fix invalid transact2 message (we were sometimes trying to interpret
Steve French099a58f2005-04-28 22:41:07 -0700168oplock breaks as SMB responses). Add ioctl for checking that the
169current uid matches the uid of the mounter (needed by umount.cifs).
170Reduce the number of large buffer allocations in cifs response processing
171(significantly reduces memory pressure under heavy stress with multiple
172processes accessing the same server at the same time).
Steve Frenchf654bac2005-04-28 22:41:04 -0700173
174Version 1.31
175------------
Linus Torvalds1da177e2005-04-16 15:20:36 -0700176Fix updates of DOS attributes and time fields so that files on NT4 servers
177do not get marked delete on close. Display sizes of cifs buffer pools in
178cifs stats. Fix oops in unmount when cifsd thread being killed by
179shutdown. Add generic readv/writev and aio support. Report inode numbers
180consistently in readdir and lookup (when serverino mount option is
181specified use the inode number that the server reports - for both lookup
182and readdir, otherwise by default the locally generated inode number is used
183for inodes created in either path since servers are not always able to
184provide unique inode numbers when exporting multiple volumes from under one
185sharename).
186
187Version 1.30
188------------
189Allow new nouser_xattr mount parm to disable xattr support for user namespace.
190Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
191(mostly affects NT4 servers) by retry with handle based network operation.
192Add new POSIX Query FS Info for returning statfs info more accurately.
193Handle passwords with multiple commas in them.
194
195Version 1.29
196------------
197Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
198Fix capabilities flags for large readx so as to allow reads larger than 64K.
199
200Version 1.28
201------------
202Add module init parm for large SMB buffer size (to allow it to be changed
203from its default of 16K) which is especially useful for large file copy
204when mounting with the directio mount option. Fix oops after
205returning from mount when experimental ExtendedSecurity enabled and
206SpnegoNegotiated returning invalid error. Fix case to retry better when
207peek returns from 1 to 3 bytes on socket which should have more data.
208Fixed path based calls (such as cifs lookup) to handle path names
209longer than 530 (now can handle PATH_MAX). Fix pass through authentication
210from Samba server to DC (Samba required dummy LM password).
211
212Version 1.27
213------------
214Turn off DNOTIFY (directory change notification support) by default
215(unless built with the experimental flag) to fix hang with KDE
216file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
217waiting on an SMB response) in SendReceive when session dies but
218reconnects quickly from another task. Add module init parms for
219minimum number of large and small network buffers in the buffer pools,
220and for the maximum number of simultaneous requests.
221
222Version 1.26
223------------
224Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
225and other POSIX CIFS compliant servers. Fix error mapping for getfacl
226to EOPNOTSUPP when server does not support posix acls on the wire. Fix
227improperly zeroed buffer in CIFS Unix extensions set times call.
228
229Version 1.25
230------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700231Fix internationalization problem in cifs readdir with filenames that map to
Alexey Dobriyan4de151d2006-03-22 00:13:35 +0100232longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
Linus Torvalds1da177e2005-04-16 15:20:36 -0700233for readdir to netapp servers. Fix search rewind (seek into readdir to return
234non-consecutive entries). Do not do readdir when server negotiates
235buffer size to small to fit filename. Add support for reading POSIX ACLs from
236the server (add also acl and noacl mount options).
237
238Version 1.24
239------------
240Optionally allow using server side inode numbers, rather than client generated
241ones by specifying mount option "serverino" - this is required for some apps
242to work which double check hardlinked files and have persistent inode numbers.
243
244Version 1.23
245------------
246Multiple bigendian fixes. On little endian systems (for reconnect after
247network failure) fix tcp session reconnect code so we do not try first
248to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
249as directories rather than symlinks because we can do follow link on them.
250
251Version 1.22
252------------
253Add config option to enable XATTR (extended attribute) support, mapping
254xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
255minor fixes pointed out by the Stanford SWAT checker (mostly missing
256or out of order NULL pointer checks in little used error paths).
257
258Version 1.21
259------------
260Add new mount parm to control whether mode check (generic_permission) is done
261on the client. If Unix extensions are enabled and the uids on the client
262and server do not match, client permission checks are meaningless on
263server uids that do not exist on the client (this does not affect the
264normal ACL check which occurs on the server). Fix default uid
265on mknod to match create and mkdir. Add optional mount parm to allow
266override of the default uid behavior (in which the server sets the uid
267and gid of newly created files). Normally for network filesystem mounts
268user want the server to set the uid/gid on newly created files (rather than
269using uid of the client processes you would in a local filesystem).
270
271Version 1.20
272------------
273Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
274info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
275(in build_wildcard_path_from_dentry). Fix mknod to pass type field
276(block/char/fifo) properly. Remove spurious mount warning log entry when
277credentials passed as mount argument. Set major/minor device number in
278inode for block and char devices when unix extensions enabled.
279
280Version 1.19
281------------
282Fix /proc/fs/cifs/Stats and DebugData display to handle larger
283amounts of return data. Properly limit requests to MAX_REQ (50
284is the usual maximum active multiplex SMB/CIFS requests per server).
285Do not kill cifsd (and thus hurt the other SMB session) when more than one
286session to the same server (but with different userids) exists and one
287of the two user's smb sessions is being removed while leaving the other.
288Do not loop reconnecting in cifsd demultiplex thread when admin
289kills the thread without going through unmount.
290
291Version 1.18
292------------
293Do not rename hardlinked files (since that should be a noop). Flush
294cached write behind data when reopening a file after session abend,
295except when already in write. Grab per socket sem during reconnect
296to avoid oops in sendmsg if overlapping with reconnect. Do not
297reset cached inode file size on readdir for files open for write on
298client.
299
300
301Version 1.17
302------------
303Update number of blocks in file so du command is happier (in Linux a fake
304blocksize of 512 is required for calculating number of blocks in inode).
305Fix prepare write of partial pages to read in data from server if possible.
306Fix race on tcpStatus field between unmount and reconnection code, causing
307cifsd process sometimes to hang around forever. Improve out of memory
308checks in cifs_filldir
309
310Version 1.16
311------------
312Fix incorrect file size in file handle based setattr on big endian hardware.
313Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
314and closing file structs in writepage/partialpagewrite. Add statistics
315for each mounted share (new menuconfig option). Fix endianness problem in
316volume information displayed in /proc/fs/cifs/DebugData (only affects
317affects big endian architectures). Prevent renames while constructing
318path names for open, mkdir and rmdir.
319
320Version 1.15
321------------
322Change to mempools for alloc smb request buffers and multiplex structs
323to better handle low memory problems (and potential deadlocks).
324
325Version 1.14
326------------
327Fix incomplete listings of large directories on Samba servers when Unix
328extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
329rename deadlock when writing out dirty pages at same time.
330
331Version 1.13
332------------
333Fix open of files in which O_CREATE can cause the mode to change in
334some cases. Fix case in which retry of write overlaps file close.
335Fix PPC64 build error. Reduce excessive stack usage in smb password
336hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
337
338Version 1.12
339------------
340Fixes for large file copy, signal handling, socket retry, buffer
341allocation and low memory situations.
342
343Version 1.11
344------------
345Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
346also now allowing support for specifying client netbiosname. NT4 support added.
347
348Version 1.10
349------------
350Fix reconnection (and certain failed mounts) to properly wake up the
351blocked users thread so it does not seem hung (in some cases was blocked
352until the cifs receive timeout expired). Fix spurious error logging
353to kernel log when application with open network files killed.
354
355Version 1.09
356------------

374
375Version 1.06
376------------
377Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
378This allows files that differ only in case and improves performance of file
379creation and file open to such servers. Fix semaphore conflict which causes
380slow delete of open file to Samba (which unfortunately can cause an oplock
381break to self while vfs_unlink held i_sem) which can hang for 20 seconds.

402Fix caching problem when files opened by multiple clients in which
403page cache could contain stale data, and write through did
404not occur often enough while file was still open when read ahead
405(read oplock) not allowed. Treat "sep=" when first mount option
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700406as an override of comma as the default separator between mount
Linus Torvalds1da177e2005-04-16 15:20:36 -0700407options.
408
409Version 1.01

418
419Version 0.99
420------------
421Invalidate local inode cached pages on oplock break and when last file
422instance is closed so that the client does not continue using stale local
423copy rather than later modified server copy of file. Do not reconnect
424when server drops the tcp session prematurely before negotiate
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700425protocol response. Fix oops in reopen_file when dentry freed. Allow
Linus Torvalds1da177e2005-04-16 15:20:36 -0700426the support for CIFS Unix Extensions to be disabled via proc interface.
427
428Version 0.98
429------------
430Fix hang in commit_write during reconnection of open files under heavy load.
431Fix unload_nls oops in a mount failure path. Serialize writes to same socket
432which also fixes any possible races when cifs signatures are enabled in SMBs
433being sent out of signature sequence number order.
434
435Version 0.97
436------------
437Fix byte range locking bug (endian problem) causing bad offset and
438length.
439
440Version 0.96
441------------
442Fix oops (in send_sig) caused by CIFS unmount code trying to

510redundant NTCreate/QPathInfo/close that was sent during file create.
511Enable oplock by default. Enable packet signing by default (needed to
512access many recent Windows servers)
513
514Version 0.83
515------------
516Fix oops when mounting to long server names caused by inverted parms to kmalloc.
517Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
518we will choose a cifs user session (smb uid) that better matches the local

600
601Version 0.69
602------------
603Fix buffer overrun in readdir which caused intermittent kernel oopses.
604Fix writepage code to release kmap on write data. Allow "-ip=" new
605mount option to be passed in on parameter distinct from the first part
606(server name portion of) the UNC name. Allow override of the
607tcp port of the target server via new mount option "-port="
608
609Version 0.68
610------------
611Fix search handle leak on rewind. Fix setuid and gid so that they are
612reflected in the local inode immediately. Cleanup of whitespace
613to make 2.4 and 2.5 versions more consistent.
614
615
616Version 0.67
617------------
618Fix signal sending so that captive thread (cifsd) exits on umount
619(which was causing the warning in kmem_cache_free of the request buffers
620at rmmod time). This had broken as a sideeffect of the recent global
621kernel change to daemonize. Fix memory leak in readdir code which
622showed up in "ls -R" (and applications that did search rewinding).
623
624Version 0.66
625------------

642
643Version 0.63
644------------
645Fix memory leak in AllocMidQEntry.
646Finish reconnection logic, so connection with server can be dropped

648
649Version 0.62
650------------
651Fix temporary socket leak when bad userid or password specified
652(or other SMBSessSetup failure). Increase maximum buffer size to slightly

657------------
658Fix oops when username not passed in on mount. Extensive fixes and improvements
659to error logging (strip redundant newlines, change debug macros to ensure newline
660passed in and to be more consistent). Fix writepage wrong file handle problem,
661a readonly file handle could be incorrectly used to attempt to write out
662file updates through the page cache to multiply open files. This could cause
663the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
664shares to the same Windows server when using different usernames
665(doing this to Samba servers worked but Windows was rejecting it) - now it is
666possible to use different userids when connecting to the same server from a
667Linux client. Fix oops when treeDisconnect called during unmount on
668previously freed socket.
669
670Version 0.60

683Memory mapped operations now working.
684
685Version 0.57
686------------
687Added writepage code for additional memory mapping support. Fixed leak in xids causing
688the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
689every stat call. Additional formatting cleanup.

763
764Version 0.41
765------------
766Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked

811
812Version 0.31
813------------
8141) Fixed lockrange to be correct (it was one byte too short)
815
8162) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
817show range as locked when there is a conflict with an existing lock.
818
8193) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
820in most cases. Eventually will offer optional ability to query server for the correct perms.

8223) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
823but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
824session)
825
8264) Fixed error logging of valid mount options
827
8285) Removed logging of password field.
829
8306) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
831and cleaned them up and made them more consistent with other cifs functions.
832
8337) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700834(with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
