2------------
3Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
4configure stronger authentication. Fix sfu symlinks so they can
Steve French184ed212006-02-24 06:15:11 +00005be followed (not just recognized). Fix wraparound of bcc on
6read responses when buffer size over 64K and also fix wrap of
7max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
8cifs_user_read and cifs_readpages (when EAGAIN on send of smb
Steve French08547b02006-02-28 22:39:25 +00009on socket is returned over and over). Add POSIX (advisory) byte range
10locking support (requires server with newest CIFS UNIX Extensions
Steve French083d3a22006-03-03 09:53:36 +000011to the protocol implemented). Slow down negprot slightly in port 139
12RFC1001 case to give session_init time on buggy servers.

15------------
Steve French84afc292005-12-02 13:32:45 -080016Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
Steve French0a4b92c2006-01-12 15:44:21 -080017of readpages by eliminating one extra memcpy. Allow update of file size
18from remote server even if file is open for write as long as mount is
Steve Frencheeac8042006-01-13 21:34:58 -080019directio. Recognize share mode security and send NTLM encrypted password
20on tree connect if share mode negotiated.

Steve French23e7dd72005-10-20 13:44:56 -070022Version 1.39
23------------
Steve French3abb9272005-11-28 08:16:13 -080024Defer close of a file handle slightly if pending writes depend on that handle
Steve French23e7dd72005-10-20 13:44:56 -070025(this reduces the EBADF bad file handle errors that can be logged under heavy
Steve French3c50c612005-11-10 17:31:33 -080026stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
Steve French3abb9272005-11-28 08:16:13 -080027Fix SFU style symlinks and mknod needed for servers which do not support the
28CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
29dentries so files that the client sees as deleted but that later get created
Steve French6473a552005-11-29 20:20:10 -080030on the server will be recognized. Add client side permission check on setattr.
Steve French83451872005-12-01 17:12:59 -080031Timeout stuck requests better (where server has never responded or sent corrupt
32responses)
Steve French23e7dd72005-10-20 13:44:56 -070033
Steve French190fdeb2005-10-10 11:48:26 -070034Version 1.38
35------------
36Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
37to be smaller at first (but increasing) so large write performance performance
38over GigE is better. Do not hang thread on illegal byte range lock response
39from Windows (Windows can send an RFC1001 size which does not match smb size) by
40allowing an SMBs TCP length to be up to a few bytes longer than it should be.
41wsize and rsize can now be larger than negotiated buffer size if server
42supports large readx/writex, even when directio mount flag not specified.
43Write size will in many cases now be 16K instead of 4K which greatly helps
Steve French4ca9c192005-10-10 19:52:13 -070044file copy performance on lightly loaded networks. Fix oops in dnotify
Steve French1047abc2005-10-11 19:58:06 -070045when experimental config flag enabled. Make cifsFYI more granular.
Steve French190fdeb2005-10-10 11:48:26 -070046
Steve Frencheafe8702005-09-15 21:47:30 -070047Version 1.37
48------------
49Fix readdir caching when unlink removes file in current search buffer,
50and this is followed by a rewind search to just before the deleted entry.
Steve Frenche30dcf32005-09-20 20:49:16 -070051Do not attempt to set ctime unless atime and/or mtime change requested
Steve French20962432005-09-21 22:05:57 -070052(most servers throw it away anyway). Fix length check of received smbs
Steve French70ca7342005-09-22 16:32:06 -070053to be more accurate. Fix big endian problem with mapchars mount option,
54and with a field returned by statfs.
Steve Frencheafe8702005-09-15 21:47:30 -070055
Steve Frenchc46fa8a2005-08-18 20:49:57 -070056Version 1.36
57------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -070058Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
Steve French6b8edfe2005-08-23 20:26:03 -070059For these older servers, add option for passing netbios name of server in
Steve French16abbec2005-08-30 13:10:14 -070060on mount (servernetbiosname). Add suspend support for power management, to
61avoid cifsd thread preventing software suspend from working.
Steve Frenchc46fa8a2005-08-18 20:49:57 -070062Add mount option for disabling the default behavior of sending byte range lock
63requests to the server (necessary for certain applications which break with
64mandatory lock behavior such as Evolution), and also mount option for
65requesting case insensitive matching for path based requests (requesting
66case sensitive is the default).
67
Steve Frenchf4cfd692005-07-14 18:29:02 -050068Version 1.35
69------------
70Add writepage performance improvements. Fix path name conversions
71for long filenames on mounts which were done with "mapchars" mount option
Steve Frencha10faeb22005-08-22 21:38:31 -070072specified. Ensure multiplex ids do not collide. Fix case in which
73rmmod can oops if done soon after last unmount. Fix truncated
74search (readdir) output when resume filename was a long filename.
75Fix filename conversion when mapchars mount option was specified and
76filename was a long filename.
Steve Frenchf4cfd692005-07-14 18:29:02 -050077
Steve French11aa0142005-04-28 22:41:10 -070078Version 1.34
79------------
80Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
Steve French31ca3bc2005-04-28 22:41:11 -070081Do not oops if root user kills cifs oplock kernel thread or
82kills the cifsd thread (NB: killing the cifs kernel threads is not
83recommended, unmount and rmmod cifs will kill them when they are
Steve French68575472005-04-30 11:10:57 -070084no longer needed). Fix readdir to ASCII servers (ie older servers
Steve Frenchc0c3e8e2005-08-24 14:01:13 -070085which do not support Unicode) and also require asterisk.
Steve French3079ca62005-06-09 14:44:07 -070086Fix out of memory case in which data could be written one page
87off in the page cache.
Steve French11aa0142005-04-28 22:41:10 -070088
Steve French966ca922005-04-28 22:41:08 -070089Version 1.33
90------------
91Fix caching problem, in which readdir of directory containing a file
92which was cached could cause the file's time stamp to be updated
93without invalidating the readahead data (so we could get stale
94file data on the client for that file even as the server copy changed).
Steve Frenchcd634992005-04-28 22:41:10 -070095Cleanup response processing so cifsd can not loop when abnormally
96terminated.
Steve French966ca922005-04-28 22:41:08 -070097
98
Steve Frenchf654bac2005-04-28 22:41:04 -070099Version 1.32
Linus Torvalds1da177e2005-04-16 15:20:36 -0700100------------
101Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
102transact response for an SMB request and search entry split across two frames.
Steve Frenchf654bac2005-04-28 22:41:04 -0700103Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
104as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
105unless server explicitly claims to support them in CIFS Unix extensions
Steve Frenchad009ac2005-04-28 22:41:05 -0700106POSIX ACL capability bit. Fix packet signing when multiuser mounting with
Steve Frenchcbe04762005-04-28 22:41:05 -0700107different users from the same client to the same server. Fix oops in
Steve French6a0b4822005-04-28 22:41:05 -0700108cifs_close. Add mount option for remapping reserved characters in
109filenames (also allow recognizing files with created by SFU which have any
Steve French737b7582005-04-28 22:41:06 -0700110of these seven reserved characters, except backslash, to be recognized).
Steve French848f3fc2005-04-28 22:41:07 -0700111Fix invalid transact2 message (we were sometimes trying to interpret
Steve French099a58f2005-04-28 22:41:07 -0700112oplock breaks as SMB responses). Add ioctl for checking that the
113current uid matches the uid of the mounter (needed by umount.cifs).
114Reduce the number of large buffer allocations in cifs response processing
115(significantly reduces memory pressure under heavy stress with multiple
116processes accessing the same server at the same time).
Steve Frenchf654bac2005-04-28 22:41:04 -0700117
118Version 1.31
119------------
Linus Torvalds1da177e2005-04-16 15:20:36 -0700120Fix updates of DOS attributes and time fields so that files on NT4 servers
121do not get marked delete on close. Display sizes of cifs buffer pools in
122cifs stats. Fix oops in unmount when cifsd thread being killed by
123shutdown. Add generic readv/writev and aio support. Report inode numbers
124consistently in readdir and lookup (when serverino mount option is
125specified use the inode number that the server reports - for both lookup
126and readdir, otherwise by default the locally generated inode number is used
127for inodes created in either path since servers are not always able to
128provide unique inode numbers when exporting multiple volumes from under one
129sharename).
130
131Version 1.30
132------------
133Allow new nouser_xattr mount parm to disable xattr support for user namespace.
134Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
135(mostly affects NT4 servers) by retry with handle based network operation.
136Add new POSIX Query FS Info for returning statfs info more accurately.
137Handle passwords with multiple commas in them.
138
139Version 1.29
140------------
141Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
142Fix capabilities flags for large readx so as to allow reads larger than 64K.
143
144Version 1.28
145------------
146Add module init parm for large SMB buffer size (to allow it to be changed
147from its default of 16K) which is especially useful for large file copy
148when mounting with the directio mount option. Fix oops after
149returning from mount when experimental ExtendedSecurity enabled and
150SpnegoNegotiated returning invalid error. Fix case to retry better when
151peek returns from 1 to 3 bytes on socket which should have more data.
152Fixed path based calls (such as cifs lookup) to handle path names
153longer than 530 (now can handle PATH_MAX). Fix pass through authentication
154from Samba server to DC (Samba required dummy LM password).
155
156Version 1.27
157------------
158Turn off DNOTIFY (directory change notification support) by default
159(unless built with the experimental flag) to fix hang with KDE
160file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
161waiting on an SMB response) in SendReceive when session dies but
162reconnects quickly from another task. Add module init parms for
163minimum number of large and small network buffers in the buffer pools,
164and for the maximum number of simultaneous requests.
165
166Version 1.26
167------------
168Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
169and other POSIX CIFS compliant servers. Fix error mapping for getfacl
170to EOPNOTSUPP when server does not support posix acls on the wire. Fix
171improperly zeroed buffer in CIFS Unix extensions set times call.
172
173Version 1.25
174------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700175Fix internationalization problem in cifs readdir with filenames that map to
Linus Torvalds1da177e2005-04-16 15:20:36 -0700176longer UTF8 strings than the string on the wire was in Unicode. Add workaround
177for readdir to netapp servers. Fix search rewind (seek into readdir to return
178non-consecutive entries). Do not do readdir when server negotiates
179buffer size to small to fit filename. Add support for reading POSIX ACLs from
180the server (add also acl and noacl mount options).
181
182Version 1.24
183------------
184Optionally allow using server side inode numbers, rather than client generated
185ones by specifying mount option "serverino" - this is required for some apps
186to work which double check hardlinked files and have persistent inode numbers.
187
188Version 1.23
189------------
190Multiple bigendian fixes. On little endian systems (for reconnect after
191network failure) fix tcp session reconnect code so we do not try first
192to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
193as directories rather than symlinks because we can do follow link on them.
194
195Version 1.22
196------------
197Add config option to enable XATTR (extended attribute) support, mapping
198xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
199minor fixes pointed out by the Stanford SWAT checker (mostly missing
200or out of order NULL pointer checks in little used error paths).
201
202Version 1.21
203------------
204Add new mount parm to control whether mode check (generic_permission) is done
205on the client. If Unix extensions are enabled and the uids on the client
206and server do not match, client permission checks are meaningless on
207server uids that do not exist on the client (this does not affect the
208normal ACL check which occurs on the server). Fix default uid
209on mknod to match create and mkdir. Add optional mount parm to allow
210override of the default uid behavior (in which the server sets the uid
211and gid of newly created files). Normally for network filesystem mounts
212user want the server to set the uid/gid on newly created files (rather than
213using uid of the client processes you would in a local filesystem).
214
215Version 1.20
216------------
217Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
218info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
219(in build_wildcard_path_from_dentry). Fix mknod to pass type field
220(block/char/fifo) properly. Remove spurious mount warning log entry when
221credentials passed as mount argument. Set major/minor device number in
222inode for block and char devices when unix extensions enabled.
223
224Version 1.19
225------------
226Fix /proc/fs/cifs/Stats and DebugData display to handle larger
227amounts of return data. Properly limit requests to MAX_REQ (50
228is the usual maximum active multiplex SMB/CIFS requests per server).
229Do not kill cifsd (and thus hurt the other SMB session) when more than one
230session to the same server (but with different userids) exists and one
231of the two user's smb sessions is being removed while leaving the other.
232Do not loop reconnecting in cifsd demultiplex thread when admin
233kills the thread without going through unmount.
234
235Version 1.18
236------------
237Do not rename hardlinked files (since that should be a noop). Flush
238cached write behind data when reopening a file after session abend,
239except when already in write. Grab per socket sem during reconnect
240to avoid oops in sendmsg if overlapping with reconnect. Do not
241reset cached inode file size on readdir for files open for write on
242client.
243
244
245Version 1.17
246------------
247Update number of blocks in file so du command is happier (in Linux a fake
248blocksize of 512 is required for calculating number of blocks in inode).
249Fix prepare write of partial pages to read in data from server if possible.
250Fix race on tcpStatus field between unmount and reconnection code, causing
251cifsd process sometimes to hang around forever. Improve out of memory
252checks in cifs_filldir
253
254Version 1.16
255------------
256Fix incorrect file size in file handle based setattr on big endian hardware.
257Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
258and closing file structs in writepage/partialpagewrite. Add statistics
259for each mounted share (new menuconfig option). Fix endianness problem in
260volume information displayed in /proc/fs/cifs/DebugData (only affects
261affects big endian architectures). Prevent renames while constructing
262path names for open, mkdir and rmdir.
263
264Version 1.15
265------------
266Change to mempools for alloc smb request buffers and multiplex structs
267to better handle low memory problems (and potential deadlocks).
268
269Version 1.14
270------------
271Fix incomplete listings of large directories on Samba servers when Unix
272extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
273rename deadlock when writing out dirty pages at same time.
274
275Version 1.13
276------------
277Fix open of files in which O_CREATE can cause the mode to change in
278some cases. Fix case in which retry of write overlaps file close.
279Fix PPC64 build error. Reduce excessive stack usage in smb password
280hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
281
282Version 1.12
283------------
284Fixes for large file copy, signal handling, socket retry, buffer
285allocation and low memory situations.
286
287Version 1.11
288------------
289Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
290also now allowing support for specifying client netbiosname. NT4 support added.
291
292Version 1.10
293------------
294Fix reconnection (and certain failed mounts) to properly wake up the
295blocked users thread so it does not seem hung (in some cases was blocked
296until the cifs receive timeout expired). Fix spurious error logging
297to kernel log when application with open network files killed.
298
299Version 1.09
300------------
301Fix /proc/fs module unload warning message (that could be logged
302to the kernel log). Fix intermittent failure in connectathon
303test7 (hardlink count not immediately refreshed in case in which
304inode metadata can be incorrectly kept cached when time near zero)
305
306Version 1.08
307------------
308Allow file_mode and dir_mode (specified at mount time) to be enforced
309locally (the server already enforced its own ACLs too) for servers
310that do not report the correct mode (do not support the
311CIFS Unix Extensions).
312
313Version 1.07
314------------
315Fix some small memory leaks in some unmount error paths. Fix major leak
316of cache pages in readpages causing multiple read oriented stress
317testcases (including fsx, and even large file copy) to fail over time.
318
319Version 1.06
320------------
321Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
322This allows files that differ only in case and improves performance of file
323creation and file open to such servers. Fix semaphore conflict which causes
324slow delete of open file to Samba (which unfortunately can cause an oplock
325break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
326
327Version 1.05
328------------
329fixes to cifs_readpages for fsx test case
330
331Version 1.04
332------------
333Fix caching data integrity bug when extending file size especially when no
334oplock on file. Fix spurious logging of valid already parsed mount options
335that are parsed outside of the cifs vfs such as nosuid.
336
337
338Version 1.03
339------------
340Connect to server when port number override not specified, and tcp port
341unitialized. Reset search to restart at correct file when kernel routine
342filldir returns error during large directory searches (readdir).
343
344Version 1.02
345------------
346Fix caching problem when files opened by multiple clients in which
347page cache could contain stale data, and write through did
348not occur often enough while file was still open when read ahead
349(read oplock) not allowed. Treat "sep=" when first mount option
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700350as an override of comma as the default separator between mount
Linus Torvalds1da177e2005-04-16 15:20:36 -0700351options.
352
353Version 1.01
354------------
355Allow passwords longer than 16 bytes. Allow null password string.
356
357Version 1.00
358------------
359Gracefully clean up failed mounts when attempting to mount to servers such as
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700360Windows 98 that terminate tcp sessions during protocol negotiation. Handle
Linus Torvalds1da177e2005-04-16 15:20:36 -0700361embedded commas in mount parsing of passwords.
362
363Version 0.99
364------------
365Invalidate local inode cached pages on oplock break and when last file
366instance is closed so that the client does not continue using stale local
367copy rather than later modified server copy of file. Do not reconnect
368when server drops the tcp session prematurely before negotiate
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700369protocol response. Fix oops in reopen_file when dentry freed. Allow
Linus Torvalds1da177e2005-04-16 15:20:36 -0700370the support for CIFS Unix Extensions to be disabled via proc interface.
371
372Version 0.98
373------------
374Fix hang in commit_write during reconnection of open files under heavy load.
375Fix unload_nls oops in a mount failure path. Serialize writes to same socket
376which also fixes any possible races when cifs signatures are enabled in SMBs
377being sent out of signature sequence number order.
378
379Version 0.97
380------------
381Fix byte range locking bug (endian problem) causing bad offset and
382length.
383
384Version 0.96
385------------
386Fix oops (in send_sig) caused by CIFS unmount code trying to
387wake up the demultiplex thread after it had exited. Do not log
388error on harmless oplock release of closed handle.
389
390Version 0.95
391------------
392Fix unsafe global variable usage and password hash failure on gcc 3.3.1
393Fix problem reconnecting secondary mounts to same server after session
394failure. Fix invalid dentry - race in mkdir when directory gets created
395by another client between the lookup and mkdir.
396

558
559
560Version 0.67
561------------
562Fix signal sending so that captive thread (cifsd) exits on umount
563(which was causing the warning in kmem_cache_free of the request buffers
564at rmmod time). This had broken as a sideeffect of the recent global
565kernel change to daemonize. Fix memory leak in readdir code which
566showed up in "ls -R" (and applications that did search rewinding).
567
568Version 0.66
569------------

594------------
595Fix temporary socket leak when bad userid or password specified
596(or other SMBSessSetup failure). Increase maximum buffer size to slightly

601------------
602Fix oops when username not passed in on mount. Extensive fixes and improvements
603to error logging (strip redundant newlines, change debug macros to ensure newline
604passed in and to be more consistent). Fix writepage wrong file handle problem,
605a readonly file handle could be incorrectly used to attempt to write out
606file updates through the page cache to multiply open files. This could cause
607the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
608shares to the same Windows server when using different usernames
609(doing this to Samba servers worked but Windows was rejecting it) - now it is
610possible to use different userids when connecting to the same server from a
611Linux client. Fix oops when treeDisconnect called during unmount on
612previously freed socket.

628
629Version 0.57
630------------

7581) Fixed lockrange to be correct (it was one byte too short)
759
7602) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
761show range as locked when there is a conflict with an existing lock.
762
7633) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories

769
7704) Fixed error logging of valid mount options
771
7725) Removed logging of password field.
773
7746) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
775and cleaned them up and made them more consistent with other cifs functions.
776
7777) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700778(with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
