2------------
3Fix slow oplock break when mounted to different servers at the same time and
4the tids match and we try to find matching fid on wrong server.

Steve French12b3b8f2006-02-09 21:12:47 +00006Version 1.41
7------------
8Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
9configure stronger authentication. Fix sfu symlinks so they can
Steve French184ed212006-02-24 06:15:11 +000010be followed (not just recognized). Fix wraparound of bcc on
11read responses when buffer size over 64K and also fix wrap of
12max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
13cifs_user_read and cifs_readpages (when EAGAIN on send of smb
Steve French08547b02006-02-28 22:39:25 +000014on socket is returned over and over). Add POSIX (advisory) byte range
15locking support (requires server with newest CIFS UNIX Extensions
Steve French083d3a22006-03-03 09:53:36 +000016to the protocol implemented). Slow down negprot slightly in port 139
17RFC1001 case to give session_init time on buggy servers.

Steve French83451872005-12-01 17:12:59 -080019Version 1.40
20------------
Steve French84afc292005-12-02 13:32:45 -080021Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
Steve French0a4b92c2006-01-12 15:44:21 -080022of readpages by eliminating one extra memcpy. Allow update of file size
23from remote server even if file is open for write as long as mount is
Steve Frencheeac8042006-01-13 21:34:58 -080024directio. Recognize share mode security and send NTLM encrypted password
25on tree connect if share mode negotiated.
Steve French83451872005-12-01 17:12:59 -080026
Steve French23e7dd72005-10-20 13:44:56 -070027Version 1.39
28------------
Steve French3abb9272005-11-28 08:16:13 -080029Defer close of a file handle slightly if pending writes depend on that handle
Steve French23e7dd72005-10-20 13:44:56 -070030(this reduces the EBADF bad file handle errors that can be logged under heavy
Steve French3c50c612005-11-10 17:31:33 -080031stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
Steve French3abb9272005-11-28 08:16:13 -080032Fix SFU style symlinks and mknod needed for servers which do not support the
33CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
34dentries so files that the client sees as deleted but that later get created
Steve French6473a552005-11-29 20:20:10 -080035on the server will be recognized. Add client side permission check on setattr.
Steve French83451872005-12-01 17:12:59 -080036Timeout stuck requests better (where server has never responded or sent corrupt
37responses)
Steve French23e7dd72005-10-20 13:44:56 -070038
Steve French190fdeb2005-10-10 11:48:26 -070039Version 1.38
40------------
41Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
42to be smaller at first (but increasing) so large write performance performance
43over GigE is better. Do not hang thread on illegal byte range lock response
44from Windows (Windows can send an RFC1001 size which does not match smb size) by
45allowing an SMBs TCP length to be up to a few bytes longer than it should be.
46wsize and rsize can now be larger than negotiated buffer size if server
47supports large readx/writex, even when directio mount flag not specified.
48Write size will in many cases now be 16K instead of 4K which greatly helps
Steve French4ca9c192005-10-10 19:52:13 -070049file copy performance on lightly loaded networks. Fix oops in dnotify
Steve French1047abc2005-10-11 19:58:06 -070050when experimental config flag enabled. Make cifsFYI more granular.
Steve French190fdeb2005-10-10 11:48:26 -070051
Steve Frencheafe8702005-09-15 21:47:30 -070052Version 1.37
53------------
54Fix readdir caching when unlink removes file in current search buffer,
55and this is followed by a rewind search to just before the deleted entry.
Steve Frenche30dcf32005-09-20 20:49:16 -070056Do not attempt to set ctime unless atime and/or mtime change requested
Steve French20962432005-09-21 22:05:57 -070057(most servers throw it away anyway). Fix length check of received smbs
Steve French70ca7342005-09-22 16:32:06 -070058to be more accurate. Fix big endian problem with mapchars mount option,
59and with a field returned by statfs.
Steve Frencheafe8702005-09-15 21:47:30 -070060
Steve Frenchc46fa8a2005-08-18 20:49:57 -070061Version 1.36
62------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -070063Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
Steve French6b8edfe2005-08-23 20:26:03 -070064For these older servers, add option for passing netbios name of server in
Steve French16abbec2005-08-30 13:10:14 -070065on mount (servernetbiosname). Add suspend support for power management, to
66avoid cifsd thread preventing software suspend from working.
Steve Frenchc46fa8a2005-08-18 20:49:57 -070067Add mount option for disabling the default behavior of sending byte range lock
68requests to the server (necessary for certain applications which break with
69mandatory lock behavior such as Evolution), and also mount option for
70requesting case insensitive matching for path based requests (requesting
71case sensitive is the default).
72
Steve Frenchf4cfd692005-07-14 18:29:02 -050073Version 1.35
74------------
75Add writepage performance improvements. Fix path name conversions
76for long filenames on mounts which were done with "mapchars" mount option
Steve Frencha10faeb22005-08-22 21:38:31 -070077specified. Ensure multiplex ids do not collide. Fix case in which
78rmmod can oops if done soon after last unmount. Fix truncated
79search (readdir) output when resume filename was a long filename.
80Fix filename conversion when mapchars mount option was specified and
81filename was a long filename.
Steve Frenchf4cfd692005-07-14 18:29:02 -050082
Steve French11aa0142005-04-28 22:41:10 -070083Version 1.34
84------------
85Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
Steve French31ca3bc2005-04-28 22:41:11 -070086Do not oops if root user kills cifs oplock kernel thread or
87kills the cifsd thread (NB: killing the cifs kernel threads is not
88recommended, unmount and rmmod cifs will kill them when they are
Steve French68575472005-04-30 11:10:57 -070089no longer needed). Fix readdir to ASCII servers (ie older servers
Steve Frenchc0c3e8e2005-08-24 14:01:13 -070090which do not support Unicode) and also require asterisk.
Steve French3079ca62005-06-09 14:44:07 -070091Fix out of memory case in which data could be written one page
92off in the page cache.
Steve French11aa0142005-04-28 22:41:10 -070093
Steve French966ca922005-04-28 22:41:08 -070094Version 1.33
95------------
96Fix caching problem, in which readdir of directory containing a file
97which was cached could cause the file's time stamp to be updated
98without invalidating the readahead data (so we could get stale
99file data on the client for that file even as the server copy changed).
Steve Frenchcd634992005-04-28 22:41:10 -0700100Cleanup response processing so cifsd can not loop when abnormally
101terminated.
Steve French966ca922005-04-28 22:41:08 -0700102
103
Steve Frenchf654bac2005-04-28 22:41:04 -0700104Version 1.32
Linus Torvalds1da177e2005-04-16 15:20:36 -0700105------------
106Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
107transact response for an SMB request and search entry split across two frames.
Steve Frenchf654bac2005-04-28 22:41:04 -0700108Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
109as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
110unless server explicitly claims to support them in CIFS Unix extensions
Steve Frenchad009ac2005-04-28 22:41:05 -0700111POSIX ACL capability bit. Fix packet signing when multiuser mounting with
Steve Frenchcbe04762005-04-28 22:41:05 -0700112different users from the same client to the same server. Fix oops in
Steve French6a0b4822005-04-28 22:41:05 -0700113cifs_close. Add mount option for remapping reserved characters in
114filenames (also allow recognizing files with created by SFU which have any
Steve French737b7582005-04-28 22:41:06 -0700115of these seven reserved characters, except backslash, to be recognized).
Steve French848f3fc2005-04-28 22:41:07 -0700116Fix invalid transact2 message (we were sometimes trying to interpret
Steve French099a58f2005-04-28 22:41:07 -0700117oplock breaks as SMB responses). Add ioctl for checking that the
118current uid matches the uid of the mounter (needed by umount.cifs).
119Reduce the number of large buffer allocations in cifs response processing
120(significantly reduces memory pressure under heavy stress with multiple
121processes accessing the same server at the same time).
Steve Frenchf654bac2005-04-28 22:41:04 -0700122
123Version 1.31
124------------
Linus Torvalds1da177e2005-04-16 15:20:36 -0700125Fix updates of DOS attributes and time fields so that files on NT4 servers
126do not get marked delete on close. Display sizes of cifs buffer pools in
127cifs stats. Fix oops in unmount when cifsd thread being killed by
128shutdown. Add generic readv/writev and aio support. Report inode numbers
129consistently in readdir and lookup (when serverino mount option is
130specified use the inode number that the server reports - for both lookup
131and readdir, otherwise by default the locally generated inode number is used
132for inodes created in either path since servers are not always able to
133provide unique inode numbers when exporting multiple volumes from under one
134sharename).
135
136Version 1.30
137------------
138Allow new nouser_xattr mount parm to disable xattr support for user namespace.
139Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
140(mostly affects NT4 servers) by retry with handle based network operation.
141Add new POSIX Query FS Info for returning statfs info more accurately.
142Handle passwords with multiple commas in them.
143
144Version 1.29
145------------
146Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
147Fix capabilities flags for large readx so as to allow reads larger than 64K.
148
149Version 1.28
150------------
151Add module init parm for large SMB buffer size (to allow it to be changed
152from its default of 16K) which is especially useful for large file copy
153when mounting with the directio mount option. Fix oops after
154returning from mount when experimental ExtendedSecurity enabled and
155SpnegoNegotiated returning invalid error. Fix case to retry better when
156peek returns from 1 to 3 bytes on socket which should have more data.
157Fixed path based calls (such as cifs lookup) to handle path names
158longer than 530 (now can handle PATH_MAX). Fix pass through authentication
159from Samba server to DC (Samba required dummy LM password).
160
161Version 1.27
162------------
163Turn off DNOTIFY (directory change notification support) by default
164(unless built with the experimental flag) to fix hang with KDE
165file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
166waiting on an SMB response) in SendReceive when session dies but
167reconnects quickly from another task. Add module init parms for
168minimum number of large and small network buffers in the buffer pools,
169and for the maximum number of simultaneous requests.
170
171Version 1.26
172------------
173Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
174and other POSIX CIFS compliant servers. Fix error mapping for getfacl
175to EOPNOTSUPP when server does not support posix acls on the wire. Fix
176improperly zeroed buffer in CIFS Unix extensions set times call.
177
178Version 1.25
179------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700180Fix internationalization problem in cifs readdir with filenames that map to
Alexey Dobriyan4de151d2006-03-22 00:13:35 +0100181longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
Linus Torvalds1da177e2005-04-16 15:20:36 -0700182for readdir to netapp servers. Fix search rewind (seek into readdir to return
183non-consecutive entries). Do not do readdir when server negotiates
184buffer size to small to fit filename. Add support for reading POSIX ACLs from
185the server (add also acl and noacl mount options).
186
187Version 1.24
188------------
189Optionally allow using server side inode numbers, rather than client generated
190ones by specifying mount option "serverino" - this is required for some apps
191to work which double check hardlinked files and have persistent inode numbers.
192
193Version 1.23
194------------
195Multiple bigendian fixes. On little endian systems (for reconnect after
196network failure) fix tcp session reconnect code so we do not try first
197to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
198as directories rather than symlinks because we can do follow link on them.
199
200Version 1.22
201------------
202Add config option to enable XATTR (extended attribute) support, mapping
203xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
204minor fixes pointed out by the Stanford SWAT checker (mostly missing
205or out of order NULL pointer checks in little used error paths).
206
207Version 1.21
208------------
209Add new mount parm to control whether mode check (generic_permission) is done
210on the client. If Unix extensions are enabled and the uids on the client
211and server do not match, client permission checks are meaningless on
212server uids that do not exist on the client (this does not affect the
213normal ACL check which occurs on the server). Fix default uid
214on mknod to match create and mkdir. Add optional mount parm to allow
215override of the default uid behavior (in which the server sets the uid
216and gid of newly created files). Normally for network filesystem mounts
217user want the server to set the uid/gid on newly created files (rather than
218using uid of the client processes you would in a local filesystem).
219
220Version 1.20
221------------
222Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
223info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
224(in build_wildcard_path_from_dentry). Fix mknod to pass type field
225(block/char/fifo) properly. Remove spurious mount warning log entry when
226credentials passed as mount argument. Set major/minor device number in
227inode for block and char devices when unix extensions enabled.
228
229Version 1.19
230------------
231Fix /proc/fs/cifs/Stats and DebugData display to handle larger
232amounts of return data. Properly limit requests to MAX_REQ (50
233is the usual maximum active multiplex SMB/CIFS requests per server).
234Do not kill cifsd (and thus hurt the other SMB session) when more than one
235session to the same server (but with different userids) exists and one
236of the two user's smb sessions is being removed while leaving the other.
237Do not loop reconnecting in cifsd demultiplex thread when admin
238kills the thread without going through unmount.
239
240Version 1.18
241------------
242Do not rename hardlinked files (since that should be a noop). Flush
243cached write behind data when reopening a file after session abend,
244except when already in write. Grab per socket sem during reconnect
245to avoid oops in sendmsg if overlapping with reconnect. Do not
246reset cached inode file size on readdir for files open for write on
247client.
248
249
250Version 1.17
251------------
252Update number of blocks in file so du command is happier (in Linux a fake
253blocksize of 512 is required for calculating number of blocks in inode).
254Fix prepare write of partial pages to read in data from server if possible.
255Fix race on tcpStatus field between unmount and reconnection code, causing
256cifsd process sometimes to hang around forever. Improve out of memory
257checks in cifs_filldir
258
259Version 1.16
260------------
261Fix incorrect file size in file handle based setattr on big endian hardware.
262Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
263and closing file structs in writepage/partialpagewrite. Add statistics
264for each mounted share (new menuconfig option). Fix endianness problem in
265volume information displayed in /proc/fs/cifs/DebugData (only affects
266affects big endian architectures). Prevent renames while constructing
267path names for open, mkdir and rmdir.
268
269Version 1.15
270------------
271Change to mempools for alloc smb request buffers and multiplex structs
272to better handle low memory problems (and potential deadlocks).
273
274Version 1.14
275------------
276Fix incomplete listings of large directories on Samba servers when Unix
277extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
278rename deadlock when writing out dirty pages at same time.
279
280Version 1.13
281------------
282Fix open of files in which O_CREATE can cause the mode to change in
283some cases. Fix case in which retry of write overlaps file close.
284Fix PPC64 build error. Reduce excessive stack usage in smb password
285hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
286
287Version 1.12
288------------
289Fixes for large file copy, signal handling, socket retry, buffer
290allocation and low memory situations.
291
292Version 1.11
293------------
294Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
295also now allowing support for specifying client netbiosname. NT4 support added.
296
297Version 1.10
298------------
299Fix reconnection (and certain failed mounts) to properly wake up the
300blocked users thread so it does not seem hung (in some cases was blocked
301until the cifs receive timeout expired). Fix spurious error logging
302to kernel log when application with open network files killed.
303
304Version 1.09
305------------
306Fix /proc/fs module unload warning message (that could be logged
307to the kernel log). Fix intermittent failure in connectathon
308test7 (hardlink count not immediately refreshed in case in which
309inode metadata can be incorrectly kept cached when time near zero)
310
311Version 1.08
312------------
313Allow file_mode and dir_mode (specified at mount time) to be enforced
314locally (the server already enforced its own ACLs too) for servers
315that do not report the correct mode (do not support the
316CIFS Unix Extensions).
317
318Version 1.07
319------------
320Fix some small memory leaks in some unmount error paths. Fix major leak
321of cache pages in readpages causing multiple read oriented stress
322testcases (including fsx, and even large file copy) to fail over time.
323
324Version 1.06
325------------
326Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
327This allows files that differ only in case and improves performance of file
328creation and file open to such servers. Fix semaphore conflict which causes
329slow delete of open file to Samba (which unfortunately can cause an oplock
330break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
331
332Version 1.05
333------------
334fixes to cifs_readpages for fsx test case
335
336Version 1.04
337------------
338Fix caching data integrity bug when extending file size especially when no
339oplock on file. Fix spurious logging of valid already parsed mount options
340that are parsed outside of the cifs vfs such as nosuid.
341
342
343Version 1.03
344------------
345Connect to server when port number override not specified, and tcp port
346unitialized. Reset search to restart at correct file when kernel routine
347filldir returns error during large directory searches (readdir).
348
349Version 1.02
350------------
351Fix caching problem when files opened by multiple clients in which
352page cache could contain stale data, and write through did
353not occur often enough while file was still open when read ahead
354(read oplock) not allowed. Treat "sep=" when first mount option
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700355as an override of comma as the default separator between mount
Linus Torvalds1da177e2005-04-16 15:20:36 -0700356options.
357
358Version 1.01
359------------
360Allow passwords longer than 16 bytes. Allow null password string.
361
362Version 1.00
363------------
364Gracefully clean up failed mounts when attempting to mount to servers such as
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700365Windows 98 that terminate tcp sessions during protocol negotiation. Handle
Linus Torvalds1da177e2005-04-16 15:20:36 -0700366embedded commas in mount parsing of passwords.
367
368Version 0.99
369------------
370Invalidate local inode cached pages on oplock break and when last file
371instance is closed so that the client does not continue using stale local
372copy rather than later modified server copy of file. Do not reconnect
373when server drops the tcp session prematurely before negotiate
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700374protocol response. Fix oops in reopen_file when dentry freed. Allow
Linus Torvalds1da177e2005-04-16 15:20:36 -0700375the support for CIFS Unix Extensions to be disabled via proc interface.
376
377Version 0.98
378------------
379Fix hang in commit_write during reconnection of open files under heavy load.
380Fix unload_nls oops in a mount failure path. Serialize writes to same socket
381which also fixes any possible races when cifs signatures are enabled in SMBs
382being sent out of signature sequence number order.
383
384Version 0.97
385------------
386Fix byte range locking bug (endian problem) causing bad offset and
387length.
388
389Version 0.96
390------------
391Fix oops (in send_sig) caused by CIFS unmount code trying to
392wake up the demultiplex thread after it had exited. Do not log

566------------
567Fix signal sending so that captive thread (cifsd) exits on umount
568(which was causing the warning in kmem_cache_free of the request buffers
569at rmmod time). This had broken as a sideeffect of the recent global
570kernel change to daemonize. Fix memory leak in readdir code which
571showed up in "ls -R" (and applications that did search rewinding).

606------------
607Fix oops when username not passed in on mount. Extensive fixes and improvements
608to error logging (strip redundant newlines, change debug macros to ensure newline
609passed in and to be more consistent). Fix writepage wrong file handle problem,
610a readonly file handle could be incorrectly used to attempt to write out
611file updates through the page cache to multiply open files. This could cause
612the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
613shares to the same Windows server when using different usernames
614(doing this to Samba servers worked but Windows was rejecting it) - now it is
615possible to use different userids when connecting to the same server from a
616Linux client. Fix oops when treeDisconnect called during unmount on
617previously freed socket.

774
7754) Fixed error logging of valid mount options
776
7775) Removed logging of password field.
778
7796) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
780and cleaned them up and made them more consistent with other cifs functions.
781
7827) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700783(with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
