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)
6to Unicode during mount.

Steve French13298de2006-03-03 10:45:19 +00008Version 1.42
9------------
10Fix slow oplock break when mounted to different servers at the same time and
Steve French60808232006-04-22 15:53:05 +000011the tids match and we try to find matching fid on wrong server. Fix read
12looping when signing required by server (2.6.16 kernel only). Fix readdir
13vs. rename race which could cause each to hang. Return . and .. even
14if server does not. Allow searches to skip first three entries and
15begin at any location. Fix oops in find_writeable_file.

Steve French12b3b8f2006-02-09 21:12:47 +000017Version 1.41
18------------
19Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
20configure stronger authentication. Fix sfu symlinks so they can
Steve French184ed212006-02-24 06:15:11 +000021be followed (not just recognized). Fix wraparound of bcc on
22read responses when buffer size over 64K and also fix wrap of
23max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
24cifs_user_read and cifs_readpages (when EAGAIN on send of smb
Steve French08547b02006-02-28 22:39:25 +000025on socket is returned over and over). Add POSIX (advisory) byte range
26locking support (requires server with newest CIFS UNIX Extensions
Steve French083d3a22006-03-03 09:53:36 +000027to the protocol implemented). Slow down negprot slightly in port 139
28RFC1001 case to give session_init time on buggy servers.

Steve French83451872005-12-01 17:12:59 -080030Version 1.40
31------------
Steve French84afc292005-12-02 13:32:45 -080032Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
Steve French0a4b92c2006-01-12 15:44:21 -080033of readpages by eliminating one extra memcpy. Allow update of file size
34from remote server even if file is open for write as long as mount is
Steve Frencheeac8042006-01-13 21:34:58 -080035directio. Recognize share mode security and send NTLM encrypted password
36on tree connect if share mode negotiated.
Steve French83451872005-12-01 17:12:59 -080037
Steve French23e7dd72005-10-20 13:44:56 -070038Version 1.39
39------------
Steve French3abb9272005-11-28 08:16:13 -080040Defer close of a file handle slightly if pending writes depend on that handle
Steve French23e7dd72005-10-20 13:44:56 -070041(this reduces the EBADF bad file handle errors that can be logged under heavy
Steve French3c50c612005-11-10 17:31:33 -080042stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
Steve French3abb9272005-11-28 08:16:13 -080043Fix SFU style symlinks and mknod needed for servers which do not support the
44CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
45dentries so files that the client sees as deleted but that later get created
Steve French6473a552005-11-29 20:20:10 -080046on the server will be recognized. Add client side permission check on setattr.
Steve French83451872005-12-01 17:12:59 -080047Timeout stuck requests better (where server has never responded or sent corrupt
48responses)
Steve French23e7dd72005-10-20 13:44:56 -070049
Steve French190fdeb2005-10-10 11:48:26 -070050Version 1.38
51------------
52Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
53to be smaller at first (but increasing) so large write performance performance
54over GigE is better. Do not hang thread on illegal byte range lock response
55from Windows (Windows can send an RFC1001 size which does not match smb size) by
56allowing an SMBs TCP length to be up to a few bytes longer than it should be.
57wsize and rsize can now be larger than negotiated buffer size if server
58supports large readx/writex, even when directio mount flag not specified.
59Write size will in many cases now be 16K instead of 4K which greatly helps
Steve French4ca9c192005-10-10 19:52:13 -070060file copy performance on lightly loaded networks. Fix oops in dnotify
Steve French1047abc2005-10-11 19:58:06 -070061when experimental config flag enabled. Make cifsFYI more granular.
Steve French190fdeb2005-10-10 11:48:26 -070062
Steve Frencheafe8702005-09-15 21:47:30 -070063Version 1.37
64------------
65Fix readdir caching when unlink removes file in current search buffer,
66and this is followed by a rewind search to just before the deleted entry.
Steve Frenche30dcf32005-09-20 20:49:16 -070067Do not attempt to set ctime unless atime and/or mtime change requested
Steve French20962432005-09-21 22:05:57 -070068(most servers throw it away anyway). Fix length check of received smbs
Steve French70ca7342005-09-22 16:32:06 -070069to be more accurate. Fix big endian problem with mapchars mount option,
70and with a field returned by statfs.
Steve Frencheafe8702005-09-15 21:47:30 -070071
Steve Frenchc46fa8a2005-08-18 20:49:57 -070072Version 1.36
73------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -070074Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
Steve French6b8edfe2005-08-23 20:26:03 -070075For these older servers, add option for passing netbios name of server in
Steve French16abbec2005-08-30 13:10:14 -070076on mount (servernetbiosname). Add suspend support for power management, to
77avoid cifsd thread preventing software suspend from working.
Steve Frenchc46fa8a2005-08-18 20:49:57 -070078Add mount option for disabling the default behavior of sending byte range lock
79requests to the server (necessary for certain applications which break with
80mandatory lock behavior such as Evolution), and also mount option for
81requesting case insensitive matching for path based requests (requesting
82case sensitive is the default).
83
Steve Frenchf4cfd692005-07-14 18:29:02 -050084Version 1.35
85------------
86Add writepage performance improvements. Fix path name conversions
87for long filenames on mounts which were done with "mapchars" mount option
Steve Frencha10faeb22005-08-22 21:38:31 -070088specified. Ensure multiplex ids do not collide. Fix case in which
89rmmod can oops if done soon after last unmount. Fix truncated
90search (readdir) output when resume filename was a long filename.
91Fix filename conversion when mapchars mount option was specified and
92filename was a long filename.
Steve Frenchf4cfd692005-07-14 18:29:02 -050093
Steve French11aa0142005-04-28 22:41:10 -070094Version 1.34
95------------
96Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
Steve French31ca3bc2005-04-28 22:41:11 -070097Do not oops if root user kills cifs oplock kernel thread or
98kills the cifsd thread (NB: killing the cifs kernel threads is not
99recommended, unmount and rmmod cifs will kill them when they are
Steve French68575472005-04-30 11:10:57 -0700100no longer needed). Fix readdir to ASCII servers (ie older servers
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700101which do not support Unicode) and also require asterisk.
Steve French3079ca62005-06-09 14:44:07 -0700102Fix out of memory case in which data could be written one page
103off in the page cache.
Steve French11aa0142005-04-28 22:41:10 -0700104
Steve French966ca922005-04-28 22:41:08 -0700105Version 1.33
106------------
107Fix caching problem, in which readdir of directory containing a file
108which was cached could cause the file's time stamp to be updated
109without invalidating the readahead data (so we could get stale
110file data on the client for that file even as the server copy changed).
Steve Frenchcd634992005-04-28 22:41:10 -0700111Cleanup response processing so cifsd can not loop when abnormally
112terminated.
Steve French966ca922005-04-28 22:41:08 -0700113
114
Steve Frenchf654bac2005-04-28 22:41:04 -0700115Version 1.32
Linus Torvalds1da177e2005-04-16 15:20:36 -0700116------------
117Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
118transact response for an SMB request and search entry split across two frames.
Steve Frenchf654bac2005-04-28 22:41:04 -0700119Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
120as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
121unless server explicitly claims to support them in CIFS Unix extensions
Steve Frenchad009ac2005-04-28 22:41:05 -0700122POSIX ACL capability bit. Fix packet signing when multiuser mounting with
Steve Frenchcbe04762005-04-28 22:41:05 -0700123different users from the same client to the same server. Fix oops in
Steve French6a0b4822005-04-28 22:41:05 -0700124cifs_close. Add mount option for remapping reserved characters in
125filenames (also allow recognizing files with created by SFU which have any
Steve French737b7582005-04-28 22:41:06 -0700126of these seven reserved characters, except backslash, to be recognized).
Steve French848f3fc2005-04-28 22:41:07 -0700127Fix invalid transact2 message (we were sometimes trying to interpret
Steve French099a58f2005-04-28 22:41:07 -0700128oplock breaks as SMB responses). Add ioctl for checking that the
129current uid matches the uid of the mounter (needed by umount.cifs).
130Reduce the number of large buffer allocations in cifs response processing
131(significantly reduces memory pressure under heavy stress with multiple
132processes accessing the same server at the same time).
Steve Frenchf654bac2005-04-28 22:41:04 -0700133
134Version 1.31
135------------
Linus Torvalds1da177e2005-04-16 15:20:36 -0700136Fix updates of DOS attributes and time fields so that files on NT4 servers
137do not get marked delete on close. Display sizes of cifs buffer pools in
138cifs stats. Fix oops in unmount when cifsd thread being killed by
139shutdown. Add generic readv/writev and aio support. Report inode numbers
140consistently in readdir and lookup (when serverino mount option is
141specified use the inode number that the server reports - for both lookup
142and readdir, otherwise by default the locally generated inode number is used
143for inodes created in either path since servers are not always able to
144provide unique inode numbers when exporting multiple volumes from under one
145sharename).
146
147Version 1.30
148------------
149Allow new nouser_xattr mount parm to disable xattr support for user namespace.
150Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
151(mostly affects NT4 servers) by retry with handle based network operation.
152Add new POSIX Query FS Info for returning statfs info more accurately.
153Handle passwords with multiple commas in them.
154
155Version 1.29
156------------
157Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
158Fix capabilities flags for large readx so as to allow reads larger than 64K.
159
160Version 1.28
161------------
162Add module init parm for large SMB buffer size (to allow it to be changed
163from its default of 16K) which is especially useful for large file copy
164when mounting with the directio mount option. Fix oops after
165returning from mount when experimental ExtendedSecurity enabled and
166SpnegoNegotiated returning invalid error. Fix case to retry better when
167peek returns from 1 to 3 bytes on socket which should have more data.
168Fixed path based calls (such as cifs lookup) to handle path names
169longer than 530 (now can handle PATH_MAX). Fix pass through authentication
170from Samba server to DC (Samba required dummy LM password).
171
172Version 1.27
173------------
174Turn off DNOTIFY (directory change notification support) by default
175(unless built with the experimental flag) to fix hang with KDE
176file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
177waiting on an SMB response) in SendReceive when session dies but
178reconnects quickly from another task. Add module init parms for
179minimum number of large and small network buffers in the buffer pools,
180and for the maximum number of simultaneous requests.
181
182Version 1.26
183------------
184Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
185and other POSIX CIFS compliant servers. Fix error mapping for getfacl
186to EOPNOTSUPP when server does not support posix acls on the wire. Fix
187improperly zeroed buffer in CIFS Unix extensions set times call.
188
189Version 1.25
190------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700191Fix internationalization problem in cifs readdir with filenames that map to
Alexey Dobriyan4de151d2006-03-22 00:13:35 +0100192longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
Linus Torvalds1da177e2005-04-16 15:20:36 -0700193for readdir to netapp servers. Fix search rewind (seek into readdir to return
194non-consecutive entries). Do not do readdir when server negotiates
195buffer size to small to fit filename. Add support for reading POSIX ACLs from
196the server (add also acl and noacl mount options).
197
198Version 1.24
199------------
200Optionally allow using server side inode numbers, rather than client generated
201ones by specifying mount option "serverino" - this is required for some apps
202to work which double check hardlinked files and have persistent inode numbers.
203
204Version 1.23
205------------
206Multiple bigendian fixes. On little endian systems (for reconnect after
207network failure) fix tcp session reconnect code so we do not try first
208to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
209as directories rather than symlinks because we can do follow link on them.
210
211Version 1.22
212------------
213Add config option to enable XATTR (extended attribute) support, mapping
214xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
215minor fixes pointed out by the Stanford SWAT checker (mostly missing
216or out of order NULL pointer checks in little used error paths).
217
218Version 1.21
219------------
220Add new mount parm to control whether mode check (generic_permission) is done
221on the client. If Unix extensions are enabled and the uids on the client
222and server do not match, client permission checks are meaningless on
223server uids that do not exist on the client (this does not affect the
224normal ACL check which occurs on the server). Fix default uid
225on mknod to match create and mkdir. Add optional mount parm to allow
226override of the default uid behavior (in which the server sets the uid
227and gid of newly created files). Normally for network filesystem mounts
228user want the server to set the uid/gid on newly created files (rather than
229using uid of the client processes you would in a local filesystem).
230
231Version 1.20
232------------
233Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
234info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
235(in build_wildcard_path_from_dentry). Fix mknod to pass type field
236(block/char/fifo) properly. Remove spurious mount warning log entry when
237credentials passed as mount argument. Set major/minor device number in
238inode for block and char devices when unix extensions enabled.
239
240Version 1.19
241------------
242Fix /proc/fs/cifs/Stats and DebugData display to handle larger
243amounts of return data. Properly limit requests to MAX_REQ (50
244is the usual maximum active multiplex SMB/CIFS requests per server).
245Do not kill cifsd (and thus hurt the other SMB session) when more than one
246session to the same server (but with different userids) exists and one
247of the two user's smb sessions is being removed while leaving the other.
248Do not loop reconnecting in cifsd demultiplex thread when admin
249kills the thread without going through unmount.
250
251Version 1.18
252------------
253Do not rename hardlinked files (since that should be a noop). Flush
254cached write behind data when reopening a file after session abend,
255except when already in write. Grab per socket sem during reconnect
256to avoid oops in sendmsg if overlapping with reconnect. Do not
257reset cached inode file size on readdir for files open for write on
258client.
259
260
261Version 1.17
262------------
263Update number of blocks in file so du command is happier (in Linux a fake
264blocksize of 512 is required for calculating number of blocks in inode).
265Fix prepare write of partial pages to read in data from server if possible.
266Fix race on tcpStatus field between unmount and reconnection code, causing
267cifsd process sometimes to hang around forever. Improve out of memory
268checks in cifs_filldir
269
270Version 1.16
271------------
272Fix incorrect file size in file handle based setattr on big endian hardware.
273Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
274and closing file structs in writepage/partialpagewrite. Add statistics
275for each mounted share (new menuconfig option). Fix endianness problem in
276volume information displayed in /proc/fs/cifs/DebugData (only affects
277affects big endian architectures). Prevent renames while constructing
278path names for open, mkdir and rmdir.
279
280Version 1.15
281------------
282Change to mempools for alloc smb request buffers and multiplex structs
283to better handle low memory problems (and potential deadlocks).
284
285Version 1.14
286------------
287Fix incomplete listings of large directories on Samba servers when Unix
288extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
289rename deadlock when writing out dirty pages at same time.
290
291Version 1.13
292------------
293Fix open of files in which O_CREATE can cause the mode to change in
294some cases. Fix case in which retry of write overlaps file close.
295Fix PPC64 build error. Reduce excessive stack usage in smb password
296hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
297
298Version 1.12
299------------
300Fixes for large file copy, signal handling, socket retry, buffer
301allocation and low memory situations.
302
303Version 1.11
304------------
305Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
306also now allowing support for specifying client netbiosname. NT4 support added.
307
308Version 1.10
309------------
310Fix reconnection (and certain failed mounts) to properly wake up the
311blocked users thread so it does not seem hung (in some cases was blocked
312until the cifs receive timeout expired). Fix spurious error logging
313to kernel log when application with open network files killed.
314
315Version 1.09
316------------
317Fix /proc/fs module unload warning message (that could be logged
318to the kernel log). Fix intermittent failure in connectathon
319test7 (hardlink count not immediately refreshed in case in which
320inode metadata can be incorrectly kept cached when time near zero)
321
322Version 1.08
323------------
324Allow file_mode and dir_mode (specified at mount time) to be enforced
325locally (the server already enforced its own ACLs too) for servers
326that do not report the correct mode (do not support the
327CIFS Unix Extensions).
328
329Version 1.07
330------------
331Fix some small memory leaks in some unmount error paths. Fix major leak
332of cache pages in readpages causing multiple read oriented stress
333testcases (including fsx, and even large file copy) to fail over time.
334
335Version 1.06
336------------
337Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
338This allows files that differ only in case and improves performance of file
339creation and file open to such servers. Fix semaphore conflict which causes
340slow delete of open file to Samba (which unfortunately can cause an oplock
341break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
342
343Version 1.05
344------------
345fixes to cifs_readpages for fsx test case
346
347Version 1.04
348------------
349Fix caching data integrity bug when extending file size especially when no
350oplock on file. Fix spurious logging of valid already parsed mount options
351that are parsed outside of the cifs vfs such as nosuid.
352
353
354Version 1.03
355------------
356Connect to server when port number override not specified, and tcp port
357unitialized. Reset search to restart at correct file when kernel routine
358filldir returns error during large directory searches (readdir).
359
360Version 1.02
361------------
362Fix caching problem when files opened by multiple clients in which
363page cache could contain stale data, and write through did
364not occur often enough while file was still open when read ahead
365(read oplock) not allowed. Treat "sep=" when first mount option
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700366as an override of comma as the default separator between mount
Linus Torvalds1da177e2005-04-16 15:20:36 -0700367options.
368
369Version 1.01
370------------
371Allow passwords longer than 16 bytes. Allow null password string.
372
373Version 1.00
374------------
375Gracefully clean up failed mounts when attempting to mount to servers such as
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700376Windows 98 that terminate tcp sessions during protocol negotiation. Handle
Linus Torvalds1da177e2005-04-16 15:20:36 -0700377embedded commas in mount parsing of passwords.
378
379Version 0.99
380------------
381Invalidate local inode cached pages on oplock break and when last file
382instance is closed so that the client does not continue using stale local

577------------
578Fix signal sending so that captive thread (cifsd) exits on umount
579(which was causing the warning in kmem_cache_free of the request buffers
580at rmmod time). This had broken as a sideeffect of the recent global
581kernel change to daemonize. Fix memory leak in readdir code which

617------------
618Fix oops when username not passed in on mount. Extensive fixes and improvements
619to error logging (strip redundant newlines, change debug macros to ensure newline
620passed in and to be more consistent). Fix writepage wrong file handle problem,
621a readonly file handle could be incorrectly used to attempt to write out
622file updates through the page cache to multiply open files. This could cause
623the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
624shares to the same Windows server when using different usernames
625(doing this to Samba servers worked but Windows was rejecting it) - now it is
626possible to use different userids when connecting to the same server from a
627Linux client. Fix oops when treeDisconnect called during unmount on
628previously freed socket.

7864) Fixed error logging of valid mount options
787
7885) Removed logging of password field.
789
7906) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
