2------------
Steve French7521a3c2007-07-11 18:30:34 +00003Fix NTLMv2 signing. NFS server mounted over cifs works (if cifs mount is
Steve French2d785a52007-07-15 01:48:57 +00004done with "serverino" mount option). Add support for POSIX Unlink
5(helps with certain sharing violation cases when server such as
Steve Frencha403a0a2007-07-26 15:54:16 +00006Samba supports newer POSIX CIFS Protocol Extensions). Add "nounix"
7mount option to allow disabling the CIFS Unix Extensions for just
8that mount. Fix hang on spinlock in find_writable_file (race when
9reopening file after session crash).
Steve Frenchb609f062007-07-09 07:55:14 +000010
Steve French5858ae42007-04-25 11:59:10 +000011Version 1.49
12------------
13IPv6 support. Enable ipv6 addresses to be passed on mount (put the ipv6
14address after the "ip=" mount option, at least until mount.cifs is fixed to
Steve French4523cc32007-04-30 20:13:06 +000015handle DNS host to ipv6 name translation). Accept override of uid or gid
16on mount even when Unix Extensions are negotiated (it used to be ignored
17when Unix Extensions were ignored). This allows users to override the
18default uid and gid for files when they are certain that the uids or
Jeff Layton8426c392007-05-05 03:27:49 +000019gids on the server do not match those of the client. Make "sec=none"
20mount override username (so that null user connection is attempted)
Steve French75865f82007-06-24 18:30:48 +000021to match what documentation said. Support for very large reads, over 127K,
22available to some newer servers (such as Samba 3.0.26 and later but
23note that it also requires setting CIFSMaxBufSize at module install
24time to a larger value which may hurt performance in some cases).
Jeff38c10a12007-07-06 21:10:07 +000025Make sign option force signing (or fail if server does not support it).
Steve French5858ae42007-04-25 11:59:10 +000026
27Version 1.48
Steve French3677db12007-02-26 16:46:11 +000028------------
29Fix mtime bouncing around from local idea of last write times to remote time.
30Fix hang (in i_size_read) when simultaneous size update of same remote file
Steve French8a236262007-03-06 00:31:00 +000031on smp system corrupts sequence number. Do not reread unnecessarily partial page
32(which we are about to overwrite anyway) when writing out file opened rw.
Alan Tysonf5c1e2e2007-03-10 06:05:14 +000033When DOS attribute of file on non-Unix server's file changes on the server side
34from read-only back to read-write, reflect this change in default file mode
Steve French066fcb02007-03-23 00:45:08 +000035(we had been leaving a file's mode read-only until the inode were reloaded).
36Allow setting of attribute back to ATTR_NORMAL (removing readonly dos attribute
37when archive dos attribute not set and we are changing mode back to writeable
Steve French5268df22007-04-06 19:28:16 +000038on server which does not support the Unix Extensions). Remove read only dos
39attribute on chmod when adding any write permission (ie on any of
40user/group/other (not all of user/group/other ie 0222) when
Steve French2dd29d32007-04-23 22:07:35 +000041mounted to windows. Add support for POSIX MkDir (slight performance
42enhancement and eliminates the network race between the mkdir and set
43path info of the mode).

Steve French405c5142006-12-23 18:44:33 +000046Version 1.47
47------------
48Fix oops in list_del during mount caused by unaligned string.
Steve French595dcfe2007-02-08 18:11:42 +000049Fix file corruption which could occur on some large file
50copies caused by writepages page i/o completion bug.
Steve Frencha8507902007-02-06 20:43:30 +000051Seek to SEEK_END forces check for update of file size for non-cached
Steve French8af18972007-02-14 04:42:51 +000052files. Allow file size to be updated on remote extend of locally open,
53non-cached file. Fix reconnect to newer Samba servers (or other servers
54which support the CIFS Unix/POSIX extensions) so that we again tell the
55server the Unix/POSIX cifs capabilities which we support (SetFSInfo).
56Add experimental support for new POSIX Open/Mkdir (which returns
57stat information on the open, and allows setting the mode).
Steve French405c5142006-12-23 18:44:33 +000058
Steve French2fe87f02006-09-21 07:02:52 +000059Version 1.46
60------------
61Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
Steve French4b952a92006-10-30 21:46:13 +000062Allow null user to be specified on mount ("username="). Do not return
63EINVAL on readdir when filldir fails due to overwritten blocksize
Steve French8e87d4d2006-11-02 03:45:24 +000064(fixes FC problem). Return error in rename 2nd attempt retry (ie report
65if rename by handle also fails, after rename by path fails, we were
Steve French33ec32f2006-12-08 04:14:28 +000066not reporting whether the retry worked or not). Fix NTLMv2 to
67work to Windows servers (mount with option "sec=ntlmv2").
Steve French2fe87f02006-09-21 07:02:52 +000068
Steve French3a5ff612006-07-14 22:37:11 +000069Version 1.45
70------------
71Do not time out lockw calls when using posix extensions. Do not
72time out requests if server still responding reasonably fast
Steve Frenche466e482006-08-15 13:07:18 +000073on requests on other threads. Improve POSIX locking emulation,
74(lock cancel now works, and unlock of merged range works even
75to Windows servers now). Fix oops on mount to lanman servers
Steve Frenchea4c07d2006-08-16 19:44:25 +000076(win9x, os/2 etc.) when null password. Do not send listxattr
Steve French2fe87f02006-09-21 07:02:52 +000077(SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
78problem (instantiate inodes/dentries in right order for readdir).
Steve French3a5ff612006-07-14 22:37:11 +000079
Steve French39798772006-05-31 22:40:51 +000080Version 1.44
81------------
82Rewritten sessionsetup support, including support for legacy SMB
83session setup needed for OS/2 and older servers such as Windows 95 and 98.
Steve French5bafd762006-06-07 00:18:43 +000084Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
85so we can do search (ls etc.) to OS/2. Do not send NTCreateX
86or recent levels of FindFirst unless server says it supports NT SMBs
Steve French1717ffc2006-06-08 05:41:32 +000087(instead use legacy equivalents from LANMAN dialect). Fix to allow
88NTLMv2 authentication support (now can use stronger password hashing
Steve French750d1152006-06-27 06:28:30 +000089on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
90Allow override of global cifs security flags on mount via "sec=" option(s).
Steve French39798772006-05-31 22:40:51 +000091
Steve Frenchfc94cdb2006-05-30 18:03:32 +000092Version 1.43
93------------
94POSIX locking to servers which support CIFS POSIX Extensions
Steve Frencha878fb22006-05-30 18:04:19 +000095(disabled by default controlled by proc/fs/cifs/Experimental).
96Handle conversion of long share names (especially Asian languages)
Steve French26a21b92006-05-31 18:05:34 +000097to Unicode during mount. Fix memory leak in sess struct on reconnect.
98Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
99cifs open which helps rare case when setpathinfo fails or server does
100not support it.
Steve Frenchfc94cdb2006-05-30 18:03:32 +0000101
Steve French13298de2006-03-03 10:45:19 +0000102Version 1.42
103------------
104Fix slow oplock break when mounted to different servers at the same time and
Steve French60808232006-04-22 15:53:05 +0000105the tids match and we try to find matching fid on wrong server. Fix read
106looping when signing required by server (2.6.16 kernel only). Fix readdir
107vs. rename race which could cause each to hang. Return . and .. even
108if server does not. Allow searches to skip first three entries and
109begin at any location. Fix oops in find_writeable_file.
Steve French13298de2006-03-03 10:45:19 +0000110
Steve French12b3b8f2006-02-09 21:12:47 +0000111Version 1.41
112------------
113Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
114configure stronger authentication. Fix sfu symlinks so they can
Steve French184ed212006-02-24 06:15:11 +0000115be followed (not just recognized). Fix wraparound of bcc on
116read responses when buffer size over 64K and also fix wrap of
117max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
118cifs_user_read and cifs_readpages (when EAGAIN on send of smb
Steve French08547b02006-02-28 22:39:25 +0000119on socket is returned over and over). Add POSIX (advisory) byte range
120locking support (requires server with newest CIFS UNIX Extensions
Steve French083d3a22006-03-03 09:53:36 +0000121to the protocol implemented). Slow down negprot slightly in port 139
122RFC1001 case to give session_init time on buggy servers.
Steve French12b3b8f2006-02-09 21:12:47 +0000123
Steve French83451872005-12-01 17:12:59 -0800124Version 1.40
125------------
Steve French84afc292005-12-02 13:32:45 -0800126Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
Steve French0a4b92c2006-01-12 15:44:21 -0800127of readpages by eliminating one extra memcpy. Allow update of file size
128from remote server even if file is open for write as long as mount is
Steve Frencheeac8042006-01-13 21:34:58 -0800129directio. Recognize share mode security and send NTLM encrypted password
130on tree connect if share mode negotiated.
Steve French83451872005-12-01 17:12:59 -0800131
Steve French23e7dd72005-10-20 13:44:56 -0700132Version 1.39
133------------
Steve French3abb9272005-11-28 08:16:13 -0800134Defer close of a file handle slightly if pending writes depend on that handle
Steve French23e7dd72005-10-20 13:44:56 -0700135(this reduces the EBADF bad file handle errors that can be logged under heavy
Steve French3c50c612005-11-10 17:31:33 -0800136stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
Steve French3abb9272005-11-28 08:16:13 -0800137Fix SFU style symlinks and mknod needed for servers which do not support the
138CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
139dentries so files that the client sees as deleted but that later get created
Steve French6473a552005-11-29 20:20:10 -0800140on the server will be recognized. Add client side permission check on setattr.
Steve French83451872005-12-01 17:12:59 -0800141Timeout stuck requests better (where server has never responded or sent corrupt
142responses)
Steve French23e7dd72005-10-20 13:44:56 -0700143
Steve French190fdeb2005-10-10 11:48:26 -0700144Version 1.38
145------------
146Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
147to be smaller at first (but increasing) so large write performance performance
148over GigE is better. Do not hang thread on illegal byte range lock response
149from Windows (Windows can send an RFC1001 size which does not match smb size) by
150allowing an SMBs TCP length to be up to a few bytes longer than it should be.
151wsize and rsize can now be larger than negotiated buffer size if server
152supports large readx/writex, even when directio mount flag not specified.
153Write size will in many cases now be 16K instead of 4K which greatly helps
Steve French4ca9c192005-10-10 19:52:13 -0700154file copy performance on lightly loaded networks. Fix oops in dnotify
Steve French1047abc2005-10-11 19:58:06 -0700155when experimental config flag enabled. Make cifsFYI more granular.
Steve French190fdeb2005-10-10 11:48:26 -0700156
Steve Frencheafe8702005-09-15 21:47:30 -0700157Version 1.37
158------------
159Fix readdir caching when unlink removes file in current search buffer,
160and this is followed by a rewind search to just before the deleted entry.
Steve Frenche30dcf32005-09-20 20:49:16 -0700161Do not attempt to set ctime unless atime and/or mtime change requested
Steve French20962432005-09-21 22:05:57 -0700162(most servers throw it away anyway). Fix length check of received smbs
Steve French70ca7342005-09-22 16:32:06 -0700163to be more accurate. Fix big endian problem with mapchars mount option,
164and with a field returned by statfs.
Steve Frencheafe8702005-09-15 21:47:30 -0700165
Steve Frenchc46fa8a2005-08-18 20:49:57 -0700166Version 1.36
167------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700168Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
Steve French6b8edfe2005-08-23 20:26:03 -0700169For these older servers, add option for passing netbios name of server in
Steve French16abbec2005-08-30 13:10:14 -0700170on mount (servernetbiosname). Add suspend support for power management, to
171avoid cifsd thread preventing software suspend from working.
Steve Frenchc46fa8a2005-08-18 20:49:57 -0700172Add mount option for disabling the default behavior of sending byte range lock
173requests to the server (necessary for certain applications which break with
174mandatory lock behavior such as Evolution), and also mount option for
175requesting case insensitive matching for path based requests (requesting
176case sensitive is the default).
177
Steve Frenchf4cfd692005-07-14 18:29:02 -0500178Version 1.35
179------------
180Add writepage performance improvements. Fix path name conversions
181for long filenames on mounts which were done with "mapchars" mount option
Steve Frencha10faeb22005-08-22 21:38:31 -0700182specified. Ensure multiplex ids do not collide. Fix case in which
183rmmod can oops if done soon after last unmount. Fix truncated
184search (readdir) output when resume filename was a long filename.
185Fix filename conversion when mapchars mount option was specified and
186filename was a long filename.
Steve Frenchf4cfd692005-07-14 18:29:02 -0500187
Steve French11aa0142005-04-28 22:41:10 -0700188Version 1.34
189------------
190Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
Steve French31ca3bc2005-04-28 22:41:11 -0700191Do not oops if root user kills cifs oplock kernel thread or
192kills the cifsd thread (NB: killing the cifs kernel threads is not
193recommended, unmount and rmmod cifs will kill them when they are
Steve French68575472005-04-30 11:10:57 -0700194no longer needed). Fix readdir to ASCII servers (ie older servers
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700195which do not support Unicode) and also require asterisk.
Steve French3079ca62005-06-09 14:44:07 -0700196Fix out of memory case in which data could be written one page
197off in the page cache.
Steve French11aa0142005-04-28 22:41:10 -0700198
Steve French966ca922005-04-28 22:41:08 -0700199Version 1.33
200------------
201Fix caching problem, in which readdir of directory containing a file
202which was cached could cause the file's time stamp to be updated
203without invalidating the readahead data (so we could get stale
204file data on the client for that file even as the server copy changed).
Steve Frenchcd634992005-04-28 22:41:10 -0700205Cleanup response processing so cifsd can not loop when abnormally
206terminated.
Steve French966ca922005-04-28 22:41:08 -0700207
208
Steve Frenchf654bac2005-04-28 22:41:04 -0700209Version 1.32
Linus Torvalds1da177e2005-04-16 15:20:36 -0700210------------
211Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
212transact response for an SMB request and search entry split across two frames.
Steve Frenchf654bac2005-04-28 22:41:04 -0700213Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
214as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
215unless server explicitly claims to support them in CIFS Unix extensions
Steve Frenchad009ac2005-04-28 22:41:05 -0700216POSIX ACL capability bit. Fix packet signing when multiuser mounting with
Steve Frenchcbe04762005-04-28 22:41:05 -0700217different users from the same client to the same server. Fix oops in
Steve French6a0b4822005-04-28 22:41:05 -0700218cifs_close. Add mount option for remapping reserved characters in
219filenames (also allow recognizing files with created by SFU which have any
Steve French737b7582005-04-28 22:41:06 -0700220of these seven reserved characters, except backslash, to be recognized).
Steve French848f3fc2005-04-28 22:41:07 -0700221Fix invalid transact2 message (we were sometimes trying to interpret
Steve French099a58f2005-04-28 22:41:07 -0700222oplock breaks as SMB responses). Add ioctl for checking that the
223current uid matches the uid of the mounter (needed by umount.cifs).
224Reduce the number of large buffer allocations in cifs response processing
225(significantly reduces memory pressure under heavy stress with multiple
226processes accessing the same server at the same time).
Steve Frenchf654bac2005-04-28 22:41:04 -0700227
228Version 1.31
229------------
Linus Torvalds1da177e2005-04-16 15:20:36 -0700230Fix updates of DOS attributes and time fields so that files on NT4 servers
231do not get marked delete on close. Display sizes of cifs buffer pools in
232cifs stats. Fix oops in unmount when cifsd thread being killed by
233shutdown. Add generic readv/writev and aio support. Report inode numbers
234consistently in readdir and lookup (when serverino mount option is
235specified use the inode number that the server reports - for both lookup
236and readdir, otherwise by default the locally generated inode number is used
237for inodes created in either path since servers are not always able to
238provide unique inode numbers when exporting multiple volumes from under one
239sharename).
240
241Version 1.30
242------------
243Allow new nouser_xattr mount parm to disable xattr support for user namespace.
244Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
245(mostly affects NT4 servers) by retry with handle based network operation.
246Add new POSIX Query FS Info for returning statfs info more accurately.
247Handle passwords with multiple commas in them.
248
249Version 1.29
250------------
251Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
252Fix capabilities flags for large readx so as to allow reads larger than 64K.
253
254Version 1.28
255------------
256Add module init parm for large SMB buffer size (to allow it to be changed
257from its default of 16K) which is especially useful for large file copy
258when mounting with the directio mount option. Fix oops after
259returning from mount when experimental ExtendedSecurity enabled and
260SpnegoNegotiated returning invalid error. Fix case to retry better when
261peek returns from 1 to 3 bytes on socket which should have more data.
262Fixed path based calls (such as cifs lookup) to handle path names
263longer than 530 (now can handle PATH_MAX). Fix pass through authentication
264from Samba server to DC (Samba required dummy LM password).
265
266Version 1.27
267------------
268Turn off DNOTIFY (directory change notification support) by default
269(unless built with the experimental flag) to fix hang with KDE
270file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
271waiting on an SMB response) in SendReceive when session dies but
272reconnects quickly from another task. Add module init parms for
273minimum number of large and small network buffers in the buffer pools,
274and for the maximum number of simultaneous requests.
275
276Version 1.26
277------------
278Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
279and other POSIX CIFS compliant servers. Fix error mapping for getfacl
280to EOPNOTSUPP when server does not support posix acls on the wire. Fix
281improperly zeroed buffer in CIFS Unix extensions set times call.
282
283Version 1.25
284------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700285Fix internationalization problem in cifs readdir with filenames that map to
Alexey Dobriyan4de151d2006-03-22 00:13:35 +0100286longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
Linus Torvalds1da177e2005-04-16 15:20:36 -0700287for readdir to netapp servers. Fix search rewind (seek into readdir to return
288non-consecutive entries). Do not do readdir when server negotiates
289buffer size to small to fit filename. Add support for reading POSIX ACLs from
290the server (add also acl and noacl mount options).
291
292Version 1.24
293------------
294Optionally allow using server side inode numbers, rather than client generated
295ones by specifying mount option "serverino" - this is required for some apps
296to work which double check hardlinked files and have persistent inode numbers.
297
298Version 1.23
299------------
300Multiple bigendian fixes. On little endian systems (for reconnect after
301network failure) fix tcp session reconnect code so we do not try first
302to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
303as directories rather than symlinks because we can do follow link on them.
304
305Version 1.22
306------------
307Add config option to enable XATTR (extended attribute) support, mapping
308xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
309minor fixes pointed out by the Stanford SWAT checker (mostly missing
310or out of order NULL pointer checks in little used error paths).
311
312Version 1.21
313------------
314Add new mount parm to control whether mode check (generic_permission) is done
315on the client. If Unix extensions are enabled and the uids on the client
316and server do not match, client permission checks are meaningless on
317server uids that do not exist on the client (this does not affect the
318normal ACL check which occurs on the server). Fix default uid
319on mknod to match create and mkdir. Add optional mount parm to allow
320override of the default uid behavior (in which the server sets the uid
321and gid of newly created files). Normally for network filesystem mounts
322user want the server to set the uid/gid on newly created files (rather than
323using uid of the client processes you would in a local filesystem).
324
325Version 1.20
326------------
327Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
328info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
329(in build_wildcard_path_from_dentry). Fix mknod to pass type field
330(block/char/fifo) properly. Remove spurious mount warning log entry when
331credentials passed as mount argument. Set major/minor device number in
332inode for block and char devices when unix extensions enabled.
333
334Version 1.19
335------------
336Fix /proc/fs/cifs/Stats and DebugData display to handle larger
337amounts of return data. Properly limit requests to MAX_REQ (50
338is the usual maximum active multiplex SMB/CIFS requests per server).
339Do not kill cifsd (and thus hurt the other SMB session) when more than one
340session to the same server (but with different userids) exists and one
341of the two user's smb sessions is being removed while leaving the other.
342Do not loop reconnecting in cifsd demultiplex thread when admin
343kills the thread without going through unmount.
344
345Version 1.18
346------------
347Do not rename hardlinked files (since that should be a noop). Flush
348cached write behind data when reopening a file after session abend,
349except when already in write. Grab per socket sem during reconnect
350to avoid oops in sendmsg if overlapping with reconnect. Do not
351reset cached inode file size on readdir for files open for write on
352client.
353
354
355Version 1.17
356------------
357Update number of blocks in file so du command is happier (in Linux a fake
358blocksize of 512 is required for calculating number of blocks in inode).
359Fix prepare write of partial pages to read in data from server if possible.
360Fix race on tcpStatus field between unmount and reconnection code, causing
361cifsd process sometimes to hang around forever. Improve out of memory
362checks in cifs_filldir
363
364Version 1.16
365------------
366Fix incorrect file size in file handle based setattr on big endian hardware.
367Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
368and closing file structs in writepage/partialpagewrite. Add statistics
369for each mounted share (new menuconfig option). Fix endianness problem in
370volume information displayed in /proc/fs/cifs/DebugData (only affects
371affects big endian architectures). Prevent renames while constructing
372path names for open, mkdir and rmdir.
373
374Version 1.15
375------------
376Change to mempools for alloc smb request buffers and multiplex structs
377to better handle low memory problems (and potential deadlocks).
378
379Version 1.14
380------------
381Fix incomplete listings of large directories on Samba servers when Unix
382extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
383rename deadlock when writing out dirty pages at same time.
384
385Version 1.13
386------------
387Fix open of files in which O_CREATE can cause the mode to change in
388some cases. Fix case in which retry of write overlaps file close.
389Fix PPC64 build error. Reduce excessive stack usage in smb password
390hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
391
392Version 1.12
393------------
394Fixes for large file copy, signal handling, socket retry, buffer
395allocation and low memory situations.
396
397Version 1.11
398------------
399Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
400also now allowing support for specifying client netbiosname. NT4 support added.
401
402Version 1.10
403------------
404Fix reconnection (and certain failed mounts) to properly wake up the
405blocked users thread so it does not seem hung (in some cases was blocked
406until the cifs receive timeout expired). Fix spurious error logging
407to kernel log when application with open network files killed.
408
409Version 1.09
410------------
411Fix /proc/fs module unload warning message (that could be logged
412to the kernel log). Fix intermittent failure in connectathon
413test7 (hardlink count not immediately refreshed in case in which
414inode metadata can be incorrectly kept cached when time near zero)
415
416Version 1.08
417------------
418Allow file_mode and dir_mode (specified at mount time) to be enforced
419locally (the server already enforced its own ACLs too) for servers
420that do not report the correct mode (do not support the
421CIFS Unix Extensions).
422
423Version 1.07
424------------
425Fix some small memory leaks in some unmount error paths. Fix major leak
426of cache pages in readpages causing multiple read oriented stress
427testcases (including fsx, and even large file copy) to fail over time.
428
429Version 1.06
430------------
431Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
432This allows files that differ only in case and improves performance of file
433creation and file open to such servers. Fix semaphore conflict which causes
434slow delete of open file to Samba (which unfortunately can cause an oplock
435break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
436
437Version 1.05
438------------
439fixes to cifs_readpages for fsx test case
440
441Version 1.04
442------------
443Fix caching data integrity bug when extending file size especially when no
444oplock on file. Fix spurious logging of valid already parsed mount options
445that are parsed outside of the cifs vfs such as nosuid.
446
447
448Version 1.03
449------------
450Connect to server when port number override not specified, and tcp port
451unitialized. Reset search to restart at correct file when kernel routine
452filldir returns error during large directory searches (readdir).
453
454Version 1.02
455------------
456Fix caching problem when files opened by multiple clients in which
457page cache could contain stale data, and write through did
458not occur often enough while file was still open when read ahead
459(read oplock) not allowed. Treat "sep=" when first mount option
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700460as an override of comma as the default separator between mount
Linus Torvalds1da177e2005-04-16 15:20:36 -0700461options.
462
463Version 1.01
464------------

469Gracefully clean up failed mounts when attempting to mount to servers such as
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700470Windows 98 that terminate tcp sessions during protocol negotiation. Handle
Linus Torvalds1da177e2005-04-16 15:20:36 -0700471embedded commas in mount parsing of passwords.
472
473Version 0.99
474------------
475Invalidate local inode cached pages on oplock break and when last file
476instance is closed so that the client does not continue using stale local
477copy rather than later modified server copy of file. Do not reconnect
478when server drops the tcp session prematurely before negotiate
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700479protocol response. Fix oops in reopen_file when dentry freed. Allow
Linus Torvalds1da177e2005-04-16 15:20:36 -0700480the support for CIFS Unix Extensions to be disabled via proc interface.
481
482Version 0.98
483------------
484Fix hang in commit_write during reconnection of open files under heavy load.
485Fix unload_nls oops in a mount failure path. Serialize writes to same socket

487being sent out of signature sequence number order.
488
489Version 0.97
490------------
491Fix byte range locking bug (endian problem) causing bad offset and
492length.
493
494Version 0.96
495------------
496Fix oops (in send_sig) caused by CIFS unmount code trying to

567
568Version 0.83
569------------
570Fix oops when mounting to long server names caused by inverted parms to kmalloc.
571Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
572we will choose a cifs user session (smb uid) that better matches the local
573uid if a) the mount uid does not match the current uid and b) we have another
574session to the same server (ip address) for a different mount which

586NTLM security case. This should help Windows 2003
587network interoperability since it is common for
588packet signing to be required now. Fix statfs (stat -f)
589which recently started returning errors due to
590invalid value (-1 instead of 0) being set in the
591struct kstatfs f_ffiles field.

606
607Version 0.77
608------------
609Fix display of NTFS DFS junctions to display as symlinks.
610They are the network equivalent. Fix oops in
611cifs_partialpagewrite caused by missing spinlock protection
612of openfile linked list. Allow writebehind caching errors to
613be returned to the application at file close.
614

653mount). Add support for overriding rsize at mount time.
654
655Version 0.69
656------------
657Fix buffer overrun in readdir which caused intermittent kernel oopses.
658Fix writepage code to release kmap on write data. Allow "-ip=" new
659mount option to be passed in on parameter distinct from the first part
660(server name portion of) the UNC name. Allow override of the
661tcp port of the target server via new mount option "-port="
662
663Version 0.68
664------------

668
669
670Version 0.67
671------------
672Fix signal sending so that captive thread (cifsd) exits on umount
673(which was causing the warning in kmem_cache_free of the request buffers
674at rmmod time). This had broken as a sideeffect of the recent global
675kernel change to daemonize. Fix memory leak in readdir code which
676showed up in "ls -R" (and applications that did search rewinding).
677
678Version 0.66
679------------
680Reconnect tids and fids after session reconnection (still do not
681reconnect byte range locks though). Fix problem caching
682lookup information for directory inodes, improving performance,
683especially in deep directory trees. Fix various build warnings.
684
685Version 0.65
686------------
687Finish fixes to commit write for caching/readahead consistency. fsx
688now works to Samba servers. Fix oops caused when readahead
689was interrupted by a signal.
690
691Version 0.64
692------------
693Fix data corruption (in partial page after truncate) that caused fsx to
694fail to Windows servers. Cleaned up some extraneous error logging in
695common error paths. Add generic sendfile support.
696
697Version 0.63
698------------
699Fix memory leak in AllocMidQEntry.

704------------
705Fix temporary socket leak when bad userid or password specified
706(or other SMBSessSetup failure). Increase maximum buffer size to slightly

711------------
712Fix oops when username not passed in on mount. Extensive fixes and improvements
713to error logging (strip redundant newlines, change debug macros to ensure newline
714passed in and to be more consistent). Fix writepage wrong file handle problem,
715a readonly file handle could be incorrectly used to attempt to write out
716file updates through the page cache to multiply open files. This could cause
717the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
718shares to the same Windows server when using different usernames
719(doing this to Samba servers worked but Windows was rejecting it) - now it is
720possible to use different userids when connecting to the same server from a
721Linux client. Fix oops when treeDisconnect called during unmount on
722previously freed socket.
723
724Version 0.60

756------------
757Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
758changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
759buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
760
761Version 0.53
762------------
763More stylistic updates to better match kernel style. Add additional statistics
764for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2

853
854Version 0.33
855------------
856Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
857on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
858Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.

864
865
866Version 0.31
867------------
8681) Fixed lockrange to be correct (it was one byte too short)
869
8702) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
871show range as locked when there is a conflict with an existing lock.
872
8733) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
874in most cases. Eventually will offer optional ability to query server for the correct perms.
875
8763) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
877but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
878session)
879
8804) Fixed error logging of valid mount options
881
8825) Removed logging of password field.
883
8846) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
885and cleaned them up and made them more consistent with other cifs functions.
886
8877) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700888(with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
Linus Torvalds1da177e2005-04-16 15:20:36 -0700889nor is the symlink support using the Unix extensions
890
8918) Started adding the readlink and follow_link code
