Steve Frenchfc94cdb2006-05-30 18:03:32 +00001Version 1.43
2------------
3POSIX locking to servers which support CIFS POSIX Extensions
Steve Frencha878fb22006-05-30 18:04:19 +00004(disabled by default controlled by proc/fs/cifs/Experimental).
5Handle conversion of long share names (especially Asian languages)
Steve French26a21b92006-05-31 18:05:34 +00006to Unicode during mount. Fix memory leak in sess struct on reconnect.
7Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
8cifs open which helps rare case when setpathinfo fails or server does
9not support it.
Steve Frenchfc94cdb2006-05-30 18:03:32 +000010
Steve French13298de2006-03-03 10:45:19 +000011Version 1.42
12------------
13Fix slow oplock break when mounted to different servers at the same time and
Steve French60808232006-04-22 15:53:05 +000014the tids match and we try to find matching fid on wrong server. Fix read
15looping when signing required by server (2.6.16 kernel only). Fix readdir
16vs. rename race which could cause each to hang. Return . and .. even
17if server does not. Allow searches to skip first three entries and
18begin at any location. Fix oops in find_writeable_file.
Steve French13298de2006-03-03 10:45:19 +000019
Steve French12b3b8f2006-02-09 21:12:47 +000020Version 1.41
21------------
22Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
23configure stronger authentication. Fix sfu symlinks so they can
Steve French184ed212006-02-24 06:15:11 +000024be followed (not just recognized). Fix wraparound of bcc on
25read responses when buffer size over 64K and also fix wrap of
26max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
27cifs_user_read and cifs_readpages (when EAGAIN on send of smb
Steve French08547b02006-02-28 22:39:25 +000028on socket is returned over and over). Add POSIX (advisory) byte range
29locking support (requires server with newest CIFS UNIX Extensions
Steve French083d3a22006-03-03 09:53:36 +000030to the protocol implemented). Slow down negprot slightly in port 139
31RFC1001 case to give session_init time on buggy servers.

Steve French83451872005-12-01 17:12:59 -080033Version 1.40
34------------
Steve French84afc292005-12-02 13:32:45 -080035Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
Steve French0a4b92c2006-01-12 15:44:21 -080036of readpages by eliminating one extra memcpy. Allow update of file size
37from remote server even if file is open for write as long as mount is
Steve Frencheeac8042006-01-13 21:34:58 -080038directio. Recognize share mode security and send NTLM encrypted password
39on tree connect if share mode negotiated.
Steve French83451872005-12-01 17:12:59 -080040
Steve French23e7dd72005-10-20 13:44:56 -070041Version 1.39
42------------
Steve French3abb9272005-11-28 08:16:13 -080043Defer close of a file handle slightly if pending writes depend on that handle
Steve French23e7dd72005-10-20 13:44:56 -070044(this reduces the EBADF bad file handle errors that can be logged under heavy
Steve French3c50c612005-11-10 17:31:33 -080045stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
Steve French3abb9272005-11-28 08:16:13 -080046Fix SFU style symlinks and mknod needed for servers which do not support the
47CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
48dentries so files that the client sees as deleted but that later get created
Steve French6473a552005-11-29 20:20:10 -080049on the server will be recognized. Add client side permission check on setattr.
Steve French83451872005-12-01 17:12:59 -080050Timeout stuck requests better (where server has never responded or sent corrupt
51responses)
Steve French23e7dd72005-10-20 13:44:56 -070052
Steve French190fdeb2005-10-10 11:48:26 -070053Version 1.38
54------------
55Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
56to be smaller at first (but increasing) so large write performance performance
57over GigE is better. Do not hang thread on illegal byte range lock response
58from Windows (Windows can send an RFC1001 size which does not match smb size) by
59allowing an SMBs TCP length to be up to a few bytes longer than it should be.
60wsize and rsize can now be larger than negotiated buffer size if server
61supports large readx/writex, even when directio mount flag not specified.
62Write size will in many cases now be 16K instead of 4K which greatly helps
Steve French4ca9c192005-10-10 19:52:13 -070063file copy performance on lightly loaded networks. Fix oops in dnotify
Steve French1047abc2005-10-11 19:58:06 -070064when experimental config flag enabled. Make cifsFYI more granular.
Steve French190fdeb2005-10-10 11:48:26 -070065
Steve Frencheafe8702005-09-15 21:47:30 -070066Version 1.37
67------------
68Fix readdir caching when unlink removes file in current search buffer,
69and this is followed by a rewind search to just before the deleted entry.
Steve Frenche30dcf32005-09-20 20:49:16 -070070Do not attempt to set ctime unless atime and/or mtime change requested
Steve French20962432005-09-21 22:05:57 -070071(most servers throw it away anyway). Fix length check of received smbs
Steve French70ca7342005-09-22 16:32:06 -070072to be more accurate. Fix big endian problem with mapchars mount option,
73and with a field returned by statfs.
Steve Frencheafe8702005-09-15 21:47:30 -070074
Steve Frenchc46fa8a2005-08-18 20:49:57 -070075Version 1.36
76------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -070077Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
Steve French6b8edfe2005-08-23 20:26:03 -070078For these older servers, add option for passing netbios name of server in
Steve French16abbec2005-08-30 13:10:14 -070079on mount (servernetbiosname). Add suspend support for power management, to
80avoid cifsd thread preventing software suspend from working.
Steve Frenchc46fa8a2005-08-18 20:49:57 -070081Add mount option for disabling the default behavior of sending byte range lock
82requests to the server (necessary for certain applications which break with
83mandatory lock behavior such as Evolution), and also mount option for
84requesting case insensitive matching for path based requests (requesting
85case sensitive is the default).
86
Steve Frenchf4cfd692005-07-14 18:29:02 -050087Version 1.35
88------------
89Add writepage performance improvements. Fix path name conversions
90for long filenames on mounts which were done with "mapchars" mount option
Steve Frencha10faeb22005-08-22 21:38:31 -070091specified. Ensure multiplex ids do not collide. Fix case in which
92rmmod can oops if done soon after last unmount. Fix truncated
93search (readdir) output when resume filename was a long filename.
94Fix filename conversion when mapchars mount option was specified and
95filename was a long filename.
Steve Frenchf4cfd692005-07-14 18:29:02 -050096
Steve French11aa0142005-04-28 22:41:10 -070097Version 1.34
98------------
99Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
Steve French31ca3bc2005-04-28 22:41:11 -0700100Do not oops if root user kills cifs oplock kernel thread or
101kills the cifsd thread (NB: killing the cifs kernel threads is not
102recommended, unmount and rmmod cifs will kill them when they are
Steve French68575472005-04-30 11:10:57 -0700103no longer needed). Fix readdir to ASCII servers (ie older servers
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700104which do not support Unicode) and also require asterisk.
Steve French3079ca62005-06-09 14:44:07 -0700105Fix out of memory case in which data could be written one page
106off in the page cache.
Steve French11aa0142005-04-28 22:41:10 -0700107
Steve French966ca922005-04-28 22:41:08 -0700108Version 1.33
109------------
110Fix caching problem, in which readdir of directory containing a file
111which was cached could cause the file's time stamp to be updated
112without invalidating the readahead data (so we could get stale
113file data on the client for that file even as the server copy changed).
Steve Frenchcd634992005-04-28 22:41:10 -0700114Cleanup response processing so cifsd can not loop when abnormally
115terminated.
Steve French966ca922005-04-28 22:41:08 -0700116
117
Steve Frenchf654bac2005-04-28 22:41:04 -0700118Version 1.32
Linus Torvalds1da177e2005-04-16 15:20:36 -0700119------------
120Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
121transact response for an SMB request and search entry split across two frames.
Steve Frenchf654bac2005-04-28 22:41:04 -0700122Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
123as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
124unless server explicitly claims to support them in CIFS Unix extensions
Steve Frenchad009ac2005-04-28 22:41:05 -0700125POSIX ACL capability bit. Fix packet signing when multiuser mounting with
Steve Frenchcbe04762005-04-28 22:41:05 -0700126different users from the same client to the same server. Fix oops in
Steve French6a0b4822005-04-28 22:41:05 -0700127cifs_close. Add mount option for remapping reserved characters in
128filenames (also allow recognizing files with created by SFU which have any
Steve French737b7582005-04-28 22:41:06 -0700129of these seven reserved characters, except backslash, to be recognized).
Steve French848f3fc2005-04-28 22:41:07 -0700130Fix invalid transact2 message (we were sometimes trying to interpret
Steve French099a58f2005-04-28 22:41:07 -0700131oplock breaks as SMB responses). Add ioctl for checking that the
132current uid matches the uid of the mounter (needed by umount.cifs).
133Reduce the number of large buffer allocations in cifs response processing
134(significantly reduces memory pressure under heavy stress with multiple
135processes accessing the same server at the same time).
Steve Frenchf654bac2005-04-28 22:41:04 -0700136
137Version 1.31
138------------
Linus Torvalds1da177e2005-04-16 15:20:36 -0700139Fix updates of DOS attributes and time fields so that files on NT4 servers
140do not get marked delete on close. Display sizes of cifs buffer pools in
141cifs stats. Fix oops in unmount when cifsd thread being killed by
142shutdown. Add generic readv/writev and aio support. Report inode numbers
143consistently in readdir and lookup (when serverino mount option is
144specified use the inode number that the server reports - for both lookup
145and readdir, otherwise by default the locally generated inode number is used
146for inodes created in either path since servers are not always able to
147provide unique inode numbers when exporting multiple volumes from under one
148sharename).
149
150Version 1.30
151------------
152Allow new nouser_xattr mount parm to disable xattr support for user namespace.
153Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
154(mostly affects NT4 servers) by retry with handle based network operation.
155Add new POSIX Query FS Info for returning statfs info more accurately.
156Handle passwords with multiple commas in them.
157
158Version 1.29
159------------
160Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
161Fix capabilities flags for large readx so as to allow reads larger than 64K.
162
163Version 1.28
164------------
165Add module init parm for large SMB buffer size (to allow it to be changed
166from its default of 16K) which is especially useful for large file copy
167when mounting with the directio mount option. Fix oops after
168returning from mount when experimental ExtendedSecurity enabled and
169SpnegoNegotiated returning invalid error. Fix case to retry better when
170peek returns from 1 to 3 bytes on socket which should have more data.
171Fixed path based calls (such as cifs lookup) to handle path names
172longer than 530 (now can handle PATH_MAX). Fix pass through authentication
173from Samba server to DC (Samba required dummy LM password).
174
175Version 1.27
176------------
177Turn off DNOTIFY (directory change notification support) by default
178(unless built with the experimental flag) to fix hang with KDE
179file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
180waiting on an SMB response) in SendReceive when session dies but
181reconnects quickly from another task. Add module init parms for
182minimum number of large and small network buffers in the buffer pools,
183and for the maximum number of simultaneous requests.
184
185Version 1.26
186------------
187Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
188and other POSIX CIFS compliant servers. Fix error mapping for getfacl
189to EOPNOTSUPP when server does not support posix acls on the wire. Fix
190improperly zeroed buffer in CIFS Unix extensions set times call.
191
192Version 1.25
193------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700194Fix internationalization problem in cifs readdir with filenames that map to
Alexey Dobriyan4de151d2006-03-22 00:13:35 +0100195longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
Linus Torvalds1da177e2005-04-16 15:20:36 -0700196for readdir to netapp servers. Fix search rewind (seek into readdir to return
197non-consecutive entries). Do not do readdir when server negotiates
198buffer size to small to fit filename. Add support for reading POSIX ACLs from
199the server (add also acl and noacl mount options).
200
201Version 1.24
202------------
203Optionally allow using server side inode numbers, rather than client generated
204ones by specifying mount option "serverino" - this is required for some apps
205to work which double check hardlinked files and have persistent inode numbers.
206
207Version 1.23
208------------
209Multiple bigendian fixes. On little endian systems (for reconnect after
210network failure) fix tcp session reconnect code so we do not try first
211to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
212as directories rather than symlinks because we can do follow link on them.
213
214Version 1.22
215------------
216Add config option to enable XATTR (extended attribute) support, mapping
217xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
218minor fixes pointed out by the Stanford SWAT checker (mostly missing
219or out of order NULL pointer checks in little used error paths).
220
221Version 1.21
222------------
223Add new mount parm to control whether mode check (generic_permission) is done
224on the client. If Unix extensions are enabled and the uids on the client
225and server do not match, client permission checks are meaningless on
226server uids that do not exist on the client (this does not affect the
227normal ACL check which occurs on the server). Fix default uid
228on mknod to match create and mkdir. Add optional mount parm to allow
229override of the default uid behavior (in which the server sets the uid
230and gid of newly created files). Normally for network filesystem mounts
231user want the server to set the uid/gid on newly created files (rather than
232using uid of the client processes you would in a local filesystem).
233
234Version 1.20
235------------
236Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
237info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
238(in build_wildcard_path_from_dentry). Fix mknod to pass type field
239(block/char/fifo) properly. Remove spurious mount warning log entry when
240credentials passed as mount argument. Set major/minor device number in
241inode for block and char devices when unix extensions enabled.
242
243Version 1.19
244------------
245Fix /proc/fs/cifs/Stats and DebugData display to handle larger
246amounts of return data. Properly limit requests to MAX_REQ (50
247is the usual maximum active multiplex SMB/CIFS requests per server).
248Do not kill cifsd (and thus hurt the other SMB session) when more than one
249session to the same server (but with different userids) exists and one
250of the two user's smb sessions is being removed while leaving the other.
251Do not loop reconnecting in cifsd demultiplex thread when admin
252kills the thread without going through unmount.
253
254Version 1.18
255------------
256Do not rename hardlinked files (since that should be a noop). Flush
257cached write behind data when reopening a file after session abend,
258except when already in write. Grab per socket sem during reconnect
259to avoid oops in sendmsg if overlapping with reconnect. Do not
260reset cached inode file size on readdir for files open for write on
261client.
262
263
264Version 1.17
265------------
266Update number of blocks in file so du command is happier (in Linux a fake
267blocksize of 512 is required for calculating number of blocks in inode).
268Fix prepare write of partial pages to read in data from server if possible.
269Fix race on tcpStatus field between unmount and reconnection code, causing
270cifsd process sometimes to hang around forever. Improve out of memory
271checks in cifs_filldir
272
273Version 1.16
274------------
275Fix incorrect file size in file handle based setattr on big endian hardware.
276Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
277and closing file structs in writepage/partialpagewrite. Add statistics
278for each mounted share (new menuconfig option). Fix endianness problem in
279volume information displayed in /proc/fs/cifs/DebugData (only affects
280affects big endian architectures). Prevent renames while constructing
281path names for open, mkdir and rmdir.
282
283Version 1.15
284------------
285Change to mempools for alloc smb request buffers and multiplex structs
286to better handle low memory problems (and potential deadlocks).
287
288Version 1.14
289------------
290Fix incomplete listings of large directories on Samba servers when Unix
291extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
292rename deadlock when writing out dirty pages at same time.
293
294Version 1.13
295------------
296Fix open of files in which O_CREATE can cause the mode to change in
297some cases. Fix case in which retry of write overlaps file close.
298Fix PPC64 build error. Reduce excessive stack usage in smb password
299hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
300
301Version 1.12
302------------
303Fixes for large file copy, signal handling, socket retry, buffer
304allocation and low memory situations.
305
306Version 1.11
307------------
308Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
309also now allowing support for specifying client netbiosname. NT4 support added.
310
311Version 1.10
312------------
313Fix reconnection (and certain failed mounts) to properly wake up the
314blocked users thread so it does not seem hung (in some cases was blocked
315until the cifs receive timeout expired). Fix spurious error logging
316to kernel log when application with open network files killed.
317
318Version 1.09
319------------
320Fix /proc/fs module unload warning message (that could be logged
321to the kernel log). Fix intermittent failure in connectathon
322test7 (hardlink count not immediately refreshed in case in which
323inode metadata can be incorrectly kept cached when time near zero)
324
325Version 1.08
326------------
327Allow file_mode and dir_mode (specified at mount time) to be enforced
328locally (the server already enforced its own ACLs too) for servers
329that do not report the correct mode (do not support the
330CIFS Unix Extensions).
331
332Version 1.07
333------------
334Fix some small memory leaks in some unmount error paths. Fix major leak
335of cache pages in readpages causing multiple read oriented stress
336testcases (including fsx, and even large file copy) to fail over time.
337
338Version 1.06
339------------
340Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
341This allows files that differ only in case and improves performance of file
342creation and file open to such servers. Fix semaphore conflict which causes
343slow delete of open file to Samba (which unfortunately can cause an oplock
344break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
345
346Version 1.05
347------------
348fixes to cifs_readpages for fsx test case
349
350Version 1.04
351------------
352Fix caching data integrity bug when extending file size especially when no
353oplock on file. Fix spurious logging of valid already parsed mount options
354that are parsed outside of the cifs vfs such as nosuid.
355
356
357Version 1.03
358------------
359Connect to server when port number override not specified, and tcp port
360unitialized. Reset search to restart at correct file when kernel routine
361filldir returns error during large directory searches (readdir).
362
363Version 1.02
364------------
365Fix caching problem when files opened by multiple clients in which
366page cache could contain stale data, and write through did
367not occur often enough while file was still open when read ahead
368(read oplock) not allowed. Treat "sep=" when first mount option
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700369as an override of comma as the default separator between mount
Linus Torvalds1da177e2005-04-16 15:20:36 -0700370options.
371
372Version 1.01
373------------
374Allow passwords longer than 16 bytes. Allow null password string.
375
376Version 1.00
377------------
378Gracefully clean up failed mounts when attempting to mount to servers such as
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700379Windows 98 that terminate tcp sessions during protocol negotiation. Handle
Linus Torvalds1da177e2005-04-16 15:20:36 -0700380embedded commas in mount parsing of passwords.
381

577
578
579Version 0.67
580------------
581Fix signal sending so that captive thread (cifsd) exits on umount
582(which was causing the warning in kmem_cache_free of the request buffers
583at rmmod time). This had broken as a sideeffect of the recent global
584kernel change to daemonize. Fix memory leak in readdir code which
585showed up in "ls -R" (and applications that did search rewinding).

620------------
621Fix oops when username not passed in on mount. Extensive fixes and improvements
622to error logging (strip redundant newlines, change debug macros to ensure newline
623passed in and to be more consistent). Fix writepage wrong file handle problem,
624a readonly file handle could be incorrectly used to attempt to write out
625file updates through the page cache to multiply open files. This could cause
626the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
627shares to the same Windows server when using different usernames
628(doing this to Samba servers worked but Windows was rejecting it) - now it is
629possible to use different userids when connecting to the same server from a
630Linux client. Fix oops when treeDisconnect called during unmount on
631previously freed socket.

7894) Fixed error logging of valid mount options
790
7915) Removed logging of password field.
792
7936) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
