Steve French39798772006-05-31 22:40:51 +00001Version 1.44
2------------
3Rewritten sessionsetup support, including support for legacy SMB
4session setup needed for OS/2 and older servers such as Windows 95 and 98.

Steve Frenchfc94cdb2006-05-30 18:03:32 +00006Version 1.43
7------------
8POSIX locking to servers which support CIFS POSIX Extensions
Steve Frencha878fb22006-05-30 18:04:19 +00009(disabled by default controlled by proc/fs/cifs/Experimental).
10Handle conversion of long share names (especially Asian languages)
Steve French26a21b92006-05-31 18:05:34 +000011to Unicode during mount. Fix memory leak in sess struct on reconnect.
12Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
13cifs open which helps rare case when setpathinfo fails or server does
14not support it.

Steve French13298de2006-03-03 10:45:19 +000016Version 1.42
17------------
18Fix slow oplock break when mounted to different servers at the same time and
Steve French60808232006-04-22 15:53:05 +000019the tids match and we try to find matching fid on wrong server. Fix read
20looping when signing required by server (2.6.16 kernel only). Fix readdir
21vs. rename race which could cause each to hang. Return . and .. even
22if server does not. Allow searches to skip first three entries and
23begin at any location. Fix oops in find_writeable_file.
Steve French13298de2006-03-03 10:45:19 +000024
Steve French12b3b8f2006-02-09 21:12:47 +000025Version 1.41
26------------
27Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
28configure stronger authentication. Fix sfu symlinks so they can
Steve French184ed212006-02-24 06:15:11 +000029be followed (not just recognized). Fix wraparound of bcc on
30read responses when buffer size over 64K and also fix wrap of
31max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
32cifs_user_read and cifs_readpages (when EAGAIN on send of smb
Steve French08547b02006-02-28 22:39:25 +000033on socket is returned over and over). Add POSIX (advisory) byte range
34locking support (requires server with newest CIFS UNIX Extensions
Steve French083d3a22006-03-03 09:53:36 +000035to the protocol implemented). Slow down negprot slightly in port 139
36RFC1001 case to give session_init time on buggy servers.

Steve French83451872005-12-01 17:12:59 -080038Version 1.40
39------------
Steve French84afc292005-12-02 13:32:45 -080040Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
Steve French0a4b92c2006-01-12 15:44:21 -080041of readpages by eliminating one extra memcpy. Allow update of file size
42from remote server even if file is open for write as long as mount is
Steve Frencheeac8042006-01-13 21:34:58 -080043directio. Recognize share mode security and send NTLM encrypted password
44on tree connect if share mode negotiated.
Steve French83451872005-12-01 17:12:59 -080045
Steve French23e7dd72005-10-20 13:44:56 -070046Version 1.39
47------------
Steve French3abb9272005-11-28 08:16:13 -080048Defer close of a file handle slightly if pending writes depend on that handle
Steve French23e7dd72005-10-20 13:44:56 -070049(this reduces the EBADF bad file handle errors that can be logged under heavy
Steve French3c50c612005-11-10 17:31:33 -080050stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
Steve French3abb9272005-11-28 08:16:13 -080051Fix SFU style symlinks and mknod needed for servers which do not support the
52CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
53dentries so files that the client sees as deleted but that later get created
Steve French6473a552005-11-29 20:20:10 -080054on the server will be recognized. Add client side permission check on setattr.
Steve French83451872005-12-01 17:12:59 -080055Timeout stuck requests better (where server has never responded or sent corrupt
56responses)
Steve French23e7dd72005-10-20 13:44:56 -070057
Steve French190fdeb2005-10-10 11:48:26 -070058Version 1.38
59------------
60Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
61to be smaller at first (but increasing) so large write performance performance
62over GigE is better. Do not hang thread on illegal byte range lock response
63from Windows (Windows can send an RFC1001 size which does not match smb size) by
64allowing an SMBs TCP length to be up to a few bytes longer than it should be.
65wsize and rsize can now be larger than negotiated buffer size if server
66supports large readx/writex, even when directio mount flag not specified.
67Write size will in many cases now be 16K instead of 4K which greatly helps
Steve French4ca9c192005-10-10 19:52:13 -070068file copy performance on lightly loaded networks. Fix oops in dnotify
Steve French1047abc2005-10-11 19:58:06 -070069when experimental config flag enabled. Make cifsFYI more granular.
Steve French190fdeb2005-10-10 11:48:26 -070070
Steve Frencheafe8702005-09-15 21:47:30 -070071Version 1.37
72------------
73Fix readdir caching when unlink removes file in current search buffer,
74and this is followed by a rewind search to just before the deleted entry.
Steve Frenche30dcf32005-09-20 20:49:16 -070075Do not attempt to set ctime unless atime and/or mtime change requested
Steve French20962432005-09-21 22:05:57 -070076(most servers throw it away anyway). Fix length check of received smbs
Steve French70ca7342005-09-22 16:32:06 -070077to be more accurate. Fix big endian problem with mapchars mount option,
78and with a field returned by statfs.
Steve Frencheafe8702005-09-15 21:47:30 -070079
Steve Frenchc46fa8a2005-08-18 20:49:57 -070080Version 1.36
81------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -070082Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
Steve French6b8edfe2005-08-23 20:26:03 -070083For these older servers, add option for passing netbios name of server in
Steve French16abbec2005-08-30 13:10:14 -070084on mount (servernetbiosname). Add suspend support for power management, to
85avoid cifsd thread preventing software suspend from working.
Steve Frenchc46fa8a2005-08-18 20:49:57 -070086Add mount option for disabling the default behavior of sending byte range lock
87requests to the server (necessary for certain applications which break with
88mandatory lock behavior such as Evolution), and also mount option for
89requesting case insensitive matching for path based requests (requesting
90case sensitive is the default).
91
Steve Frenchf4cfd692005-07-14 18:29:02 -050092Version 1.35
93------------
94Add writepage performance improvements. Fix path name conversions
95for long filenames on mounts which were done with "mapchars" mount option
Steve Frencha10faeb22005-08-22 21:38:31 -070096specified. Ensure multiplex ids do not collide. Fix case in which
97rmmod can oops if done soon after last unmount. Fix truncated
98search (readdir) output when resume filename was a long filename.
99Fix filename conversion when mapchars mount option was specified and
100filename was a long filename.
Steve Frenchf4cfd692005-07-14 18:29:02 -0500101
Steve French11aa0142005-04-28 22:41:10 -0700102Version 1.34
103------------
104Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
Steve French31ca3bc2005-04-28 22:41:11 -0700105Do not oops if root user kills cifs oplock kernel thread or
106kills the cifsd thread (NB: killing the cifs kernel threads is not
107recommended, unmount and rmmod cifs will kill them when they are
Steve French68575472005-04-30 11:10:57 -0700108no longer needed). Fix readdir to ASCII servers (ie older servers
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700109which do not support Unicode) and also require asterisk.
Steve French3079ca62005-06-09 14:44:07 -0700110Fix out of memory case in which data could be written one page
111off in the page cache.
Steve French11aa0142005-04-28 22:41:10 -0700112
Steve French966ca922005-04-28 22:41:08 -0700113Version 1.33
114------------
115Fix caching problem, in which readdir of directory containing a file
116which was cached could cause the file's time stamp to be updated
117without invalidating the readahead data (so we could get stale
118file data on the client for that file even as the server copy changed).
Steve Frenchcd634992005-04-28 22:41:10 -0700119Cleanup response processing so cifsd can not loop when abnormally
120terminated.
Steve French966ca922005-04-28 22:41:08 -0700121
122
Steve Frenchf654bac2005-04-28 22:41:04 -0700123Version 1.32
Linus Torvalds1da177e2005-04-16 15:20:36 -0700124------------
125Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
126transact response for an SMB request and search entry split across two frames.
Steve Frenchf654bac2005-04-28 22:41:04 -0700127Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
128as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
129unless server explicitly claims to support them in CIFS Unix extensions
Steve Frenchad009ac2005-04-28 22:41:05 -0700130POSIX ACL capability bit. Fix packet signing when multiuser mounting with
Steve Frenchcbe04762005-04-28 22:41:05 -0700131different users from the same client to the same server. Fix oops in
Steve French6a0b4822005-04-28 22:41:05 -0700132cifs_close. Add mount option for remapping reserved characters in
133filenames (also allow recognizing files with created by SFU which have any
Steve French737b7582005-04-28 22:41:06 -0700134of these seven reserved characters, except backslash, to be recognized).
Steve French848f3fc2005-04-28 22:41:07 -0700135Fix invalid transact2 message (we were sometimes trying to interpret
Steve French099a58f2005-04-28 22:41:07 -0700136oplock breaks as SMB responses). Add ioctl for checking that the
137current uid matches the uid of the mounter (needed by umount.cifs).
138Reduce the number of large buffer allocations in cifs response processing
139(significantly reduces memory pressure under heavy stress with multiple
140processes accessing the same server at the same time).
Steve Frenchf654bac2005-04-28 22:41:04 -0700141
142Version 1.31
143------------
Linus Torvalds1da177e2005-04-16 15:20:36 -0700144Fix updates of DOS attributes and time fields so that files on NT4 servers
145do not get marked delete on close. Display sizes of cifs buffer pools in
146cifs stats. Fix oops in unmount when cifsd thread being killed by
147shutdown. Add generic readv/writev and aio support. Report inode numbers
148consistently in readdir and lookup (when serverino mount option is
149specified use the inode number that the server reports - for both lookup
150and readdir, otherwise by default the locally generated inode number is used
151for inodes created in either path since servers are not always able to
152provide unique inode numbers when exporting multiple volumes from under one
153sharename).
154
155Version 1.30
156------------
157Allow new nouser_xattr mount parm to disable xattr support for user namespace.
158Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
159(mostly affects NT4 servers) by retry with handle based network operation.
160Add new POSIX Query FS Info for returning statfs info more accurately.
161Handle passwords with multiple commas in them.
162
163Version 1.29
164------------
165Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
166Fix capabilities flags for large readx so as to allow reads larger than 64K.
167
168Version 1.28
169------------
170Add module init parm for large SMB buffer size (to allow it to be changed
171from its default of 16K) which is especially useful for large file copy
172when mounting with the directio mount option. Fix oops after
173returning from mount when experimental ExtendedSecurity enabled and
174SpnegoNegotiated returning invalid error. Fix case to retry better when
175peek returns from 1 to 3 bytes on socket which should have more data.
176Fixed path based calls (such as cifs lookup) to handle path names
177longer than 530 (now can handle PATH_MAX). Fix pass through authentication
178from Samba server to DC (Samba required dummy LM password).
179
180Version 1.27
181------------
182Turn off DNOTIFY (directory change notification support) by default
183(unless built with the experimental flag) to fix hang with KDE
184file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
185waiting on an SMB response) in SendReceive when session dies but
186reconnects quickly from another task. Add module init parms for
187minimum number of large and small network buffers in the buffer pools,
188and for the maximum number of simultaneous requests.
189
190Version 1.26
191------------
192Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
193and other POSIX CIFS compliant servers. Fix error mapping for getfacl
194to EOPNOTSUPP when server does not support posix acls on the wire. Fix
195improperly zeroed buffer in CIFS Unix extensions set times call.
196
197Version 1.25
198------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700199Fix internationalization problem in cifs readdir with filenames that map to
Alexey Dobriyan4de151d2006-03-22 00:13:35 +0100200longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
Linus Torvalds1da177e2005-04-16 15:20:36 -0700201for readdir to netapp servers. Fix search rewind (seek into readdir to return
202non-consecutive entries). Do not do readdir when server negotiates
203buffer size to small to fit filename. Add support for reading POSIX ACLs from
204the server (add also acl and noacl mount options).
205
206Version 1.24
207------------
208Optionally allow using server side inode numbers, rather than client generated
209ones by specifying mount option "serverino" - this is required for some apps
210to work which double check hardlinked files and have persistent inode numbers.
211
212Version 1.23
213------------
214Multiple bigendian fixes. On little endian systems (for reconnect after
215network failure) fix tcp session reconnect code so we do not try first
216to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
217as directories rather than symlinks because we can do follow link on them.
218
219Version 1.22
220------------
221Add config option to enable XATTR (extended attribute) support, mapping
222xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
223minor fixes pointed out by the Stanford SWAT checker (mostly missing
224or out of order NULL pointer checks in little used error paths).
225
226Version 1.21
227------------
228Add new mount parm to control whether mode check (generic_permission) is done
229on the client. If Unix extensions are enabled and the uids on the client
230and server do not match, client permission checks are meaningless on
231server uids that do not exist on the client (this does not affect the
232normal ACL check which occurs on the server). Fix default uid
233on mknod to match create and mkdir. Add optional mount parm to allow
234override of the default uid behavior (in which the server sets the uid
235and gid of newly created files). Normally for network filesystem mounts
236user want the server to set the uid/gid on newly created files (rather than
237using uid of the client processes you would in a local filesystem).
238
239Version 1.20
240------------
241Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
242info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
243(in build_wildcard_path_from_dentry). Fix mknod to pass type field
244(block/char/fifo) properly. Remove spurious mount warning log entry when
245credentials passed as mount argument. Set major/minor device number in
246inode for block and char devices when unix extensions enabled.
247
248Version 1.19
249------------
250Fix /proc/fs/cifs/Stats and DebugData display to handle larger
251amounts of return data. Properly limit requests to MAX_REQ (50
252is the usual maximum active multiplex SMB/CIFS requests per server).
253Do not kill cifsd (and thus hurt the other SMB session) when more than one
254session to the same server (but with different userids) exists and one
255of the two user's smb sessions is being removed while leaving the other.
256Do not loop reconnecting in cifsd demultiplex thread when admin
257kills the thread without going through unmount.
258
259Version 1.18
260------------
261Do not rename hardlinked files (since that should be a noop). Flush
262cached write behind data when reopening a file after session abend,
263except when already in write. Grab per socket sem during reconnect
264to avoid oops in sendmsg if overlapping with reconnect. Do not
265reset cached inode file size on readdir for files open for write on
266client.
267
268
269Version 1.17
270------------
271Update number of blocks in file so du command is happier (in Linux a fake
272blocksize of 512 is required for calculating number of blocks in inode).
273Fix prepare write of partial pages to read in data from server if possible.
274Fix race on tcpStatus field between unmount and reconnection code, causing
275cifsd process sometimes to hang around forever. Improve out of memory
276checks in cifs_filldir
277
278Version 1.16
279------------
280Fix incorrect file size in file handle based setattr on big endian hardware.
281Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
282and closing file structs in writepage/partialpagewrite. Add statistics
283for each mounted share (new menuconfig option). Fix endianness problem in
284volume information displayed in /proc/fs/cifs/DebugData (only affects
285affects big endian architectures). Prevent renames while constructing
286path names for open, mkdir and rmdir.
287
288Version 1.15
289------------
290Change to mempools for alloc smb request buffers and multiplex structs
291to better handle low memory problems (and potential deadlocks).
292
293Version 1.14
294------------
295Fix incomplete listings of large directories on Samba servers when Unix
296extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
297rename deadlock when writing out dirty pages at same time.
298
299Version 1.13
300------------
301Fix open of files in which O_CREATE can cause the mode to change in
302some cases. Fix case in which retry of write overlaps file close.
303Fix PPC64 build error. Reduce excessive stack usage in smb password
304hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
305
306Version 1.12
307------------
308Fixes for large file copy, signal handling, socket retry, buffer
309allocation and low memory situations.
310
311Version 1.11
312------------
313Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
314also now allowing support for specifying client netbiosname. NT4 support added.
315
316Version 1.10
317------------
318Fix reconnection (and certain failed mounts) to properly wake up the
319blocked users thread so it does not seem hung (in some cases was blocked
320until the cifs receive timeout expired). Fix spurious error logging
321to kernel log when application with open network files killed.
322
323Version 1.09
324------------
325Fix /proc/fs module unload warning message (that could be logged
326to the kernel log). Fix intermittent failure in connectathon
327test7 (hardlink count not immediately refreshed in case in which
328inode metadata can be incorrectly kept cached when time near zero)
329
330Version 1.08
331------------
332Allow file_mode and dir_mode (specified at mount time) to be enforced
333locally (the server already enforced its own ACLs too) for servers
334that do not report the correct mode (do not support the
335CIFS Unix Extensions).
336
337Version 1.07
338------------
339Fix some small memory leaks in some unmount error paths. Fix major leak
340of cache pages in readpages causing multiple read oriented stress
341testcases (including fsx, and even large file copy) to fail over time.
342
343Version 1.06
344------------
345Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
346This allows files that differ only in case and improves performance of file
347creation and file open to such servers. Fix semaphore conflict which causes
348slow delete of open file to Samba (which unfortunately can cause an oplock
349break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
350
351Version 1.05
352------------
353fixes to cifs_readpages for fsx test case
354
355Version 1.04
356------------
357Fix caching data integrity bug when extending file size especially when no
358oplock on file. Fix spurious logging of valid already parsed mount options
359that are parsed outside of the cifs vfs such as nosuid.
360
361
362Version 1.03
363------------
364Connect to server when port number override not specified, and tcp port
365unitialized. Reset search to restart at correct file when kernel routine
366filldir returns error during large directory searches (readdir).
367
368Version 1.02
369------------
370Fix caching problem when files opened by multiple clients in which
371page cache could contain stale data, and write through did
372not occur often enough while file was still open when read ahead
373(read oplock) not allowed. Treat "sep=" when first mount option
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700374as an override of comma as the default separator between mount
Linus Torvalds1da177e2005-04-16 15:20:36 -0700375options.
376
377Version 1.01
378------------
379Allow passwords longer than 16 bytes. Allow null password string.
380
381Version 1.00

582
583
584Version 0.67
585------------
586Fix signal sending so that captive thread (cifsd) exits on umount
587(which was causing the warning in kmem_cache_free of the request buffers
588at rmmod time). This had broken as a sideeffect of the recent global
589kernel change to daemonize. Fix memory leak in readdir code which
590showed up in "ls -R" (and applications that did search rewinding).

625------------
626Fix oops when username not passed in on mount. Extensive fixes and improvements
627to error logging (strip redundant newlines, change debug macros to ensure newline
628passed in and to be more consistent). Fix writepage wrong file handle problem,
629a readonly file handle could be incorrectly used to attempt to write out
630file updates through the page cache to multiply open files. This could cause
631the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
632shares to the same Windows server when using different usernames
633(doing this to Samba servers worked but Windows was rejecting it) - now it is
634possible to use different userids when connecting to the same server from a
635Linux client. Fix oops when treeDisconnect called during unmount on
636previously freed socket.

7944) Fixed error logging of valid mount options
795
7965) Removed logging of password field.
797
7986) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
