2------------
Steve French84afc292005-12-02 13:32:45 -08003Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
Steve French0a4b92c2006-01-12 15:44:21 -08004of readpages by eliminating one extra memcpy. Allow update of file size
5from remote server even if file is open for write as long as mount is
Steve Frencheeac8042006-01-13 21:34:58 -08006directio. Recognize share mode security and send NTLM encrypted password
7on tree connect if share mode negotiated.

Steve French23e7dd72005-10-20 13:44:56 -07009Version 1.39
10------------
Steve French3abb9272005-11-28 08:16:13 -080011Defer close of a file handle slightly if pending writes depend on that handle
Steve French23e7dd72005-10-20 13:44:56 -070012(this reduces the EBADF bad file handle errors that can be logged under heavy
Steve French3c50c612005-11-10 17:31:33 -080013stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
Steve French3abb9272005-11-28 08:16:13 -080014Fix SFU style symlinks and mknod needed for servers which do not support the
15CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
16dentries so files that the client sees as deleted but that later get created
Steve French6473a552005-11-29 20:20:10 -080017on the server will be recognized. Add client side permission check on setattr.
Steve French83451872005-12-01 17:12:59 -080018Timeout stuck requests better (where server has never responded or sent corrupt
19responses)
Steve French23e7dd72005-10-20 13:44:56 -070020
Steve French190fdeb2005-10-10 11:48:26 -070021Version 1.38
22------------
23Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
24to be smaller at first (but increasing) so large write performance performance
25over GigE is better. Do not hang thread on illegal byte range lock response
26from Windows (Windows can send an RFC1001 size which does not match smb size) by
27allowing an SMBs TCP length to be up to a few bytes longer than it should be.
28wsize and rsize can now be larger than negotiated buffer size if server
29supports large readx/writex, even when directio mount flag not specified.
30Write size will in many cases now be 16K instead of 4K which greatly helps
Steve French4ca9c192005-10-10 19:52:13 -070031file copy performance on lightly loaded networks. Fix oops in dnotify
Steve French1047abc2005-10-11 19:58:06 -070032when experimental config flag enabled. Make cifsFYI more granular.
Steve French190fdeb2005-10-10 11:48:26 -070033
Steve Frencheafe8702005-09-15 21:47:30 -070034Version 1.37
35------------
36Fix readdir caching when unlink removes file in current search buffer,
37and this is followed by a rewind search to just before the deleted entry.
Steve Frenche30dcf32005-09-20 20:49:16 -070038Do not attempt to set ctime unless atime and/or mtime change requested
Steve French20962432005-09-21 22:05:57 -070039(most servers throw it away anyway). Fix length check of received smbs
Steve French70ca7342005-09-22 16:32:06 -070040to be more accurate. Fix big endian problem with mapchars mount option,
41and with a field returned by statfs.
Steve Frencheafe8702005-09-15 21:47:30 -070042
Steve Frenchc46fa8a2005-08-18 20:49:57 -070043Version 1.36
44------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -070045Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
Steve French6b8edfe2005-08-23 20:26:03 -070046For these older servers, add option for passing netbios name of server in
Steve French16abbec2005-08-30 13:10:14 -070047on mount (servernetbiosname). Add suspend support for power management, to
48avoid cifsd thread preventing software suspend from working.
Steve Frenchc46fa8a2005-08-18 20:49:57 -070049Add mount option for disabling the default behavior of sending byte range lock
50requests to the server (necessary for certain applications which break with
51mandatory lock behavior such as Evolution), and also mount option for
52requesting case insensitive matching for path based requests (requesting
53case sensitive is the default).
54
Steve Frenchf4cfd692005-07-14 18:29:02 -050055Version 1.35
56------------
57Add writepage performance improvements. Fix path name conversions
58for long filenames on mounts which were done with "mapchars" mount option
Steve Frencha10faeb22005-08-22 21:38:31 -070059specified. Ensure multiplex ids do not collide. Fix case in which
60rmmod can oops if done soon after last unmount. Fix truncated
61search (readdir) output when resume filename was a long filename.
62Fix filename conversion when mapchars mount option was specified and
63filename was a long filename.
Steve Frenchf4cfd692005-07-14 18:29:02 -050064
Steve French11aa0142005-04-28 22:41:10 -070065Version 1.34
66------------
67Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
Steve French31ca3bc2005-04-28 22:41:11 -070068Do not oops if root user kills cifs oplock kernel thread or
69kills the cifsd thread (NB: killing the cifs kernel threads is not
70recommended, unmount and rmmod cifs will kill them when they are
Steve French68575472005-04-30 11:10:57 -070071no longer needed). Fix readdir to ASCII servers (ie older servers
Steve Frenchc0c3e8e2005-08-24 14:01:13 -070072which do not support Unicode) and also require asterisk.
Steve French3079ca62005-06-09 14:44:07 -070073Fix out of memory case in which data could be written one page
74off in the page cache.
Steve French11aa0142005-04-28 22:41:10 -070075
Steve French966ca922005-04-28 22:41:08 -070076Version 1.33
77------------
78Fix caching problem, in which readdir of directory containing a file
79which was cached could cause the file's time stamp to be updated
80without invalidating the readahead data (so we could get stale
81file data on the client for that file even as the server copy changed).
Steve Frenchcd634992005-04-28 22:41:10 -070082Cleanup response processing so cifsd can not loop when abnormally
83terminated.
Steve French966ca922005-04-28 22:41:08 -070084
85
Steve Frenchf654bac2005-04-28 22:41:04 -070086Version 1.32
Linus Torvalds1da177e2005-04-16 15:20:36 -070087------------
88Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
89transact response for an SMB request and search entry split across two frames.
Steve Frenchf654bac2005-04-28 22:41:04 -070090Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
91as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
92unless server explicitly claims to support them in CIFS Unix extensions
Steve Frenchad009ac2005-04-28 22:41:05 -070093POSIX ACL capability bit. Fix packet signing when multiuser mounting with
Steve Frenchcbe04762005-04-28 22:41:05 -070094different users from the same client to the same server. Fix oops in
Steve French6a0b4822005-04-28 22:41:05 -070095cifs_close. Add mount option for remapping reserved characters in
96filenames (also allow recognizing files with created by SFU which have any
Steve French737b7582005-04-28 22:41:06 -070097of these seven reserved characters, except backslash, to be recognized).
Steve French848f3fc2005-04-28 22:41:07 -070098Fix invalid transact2 message (we were sometimes trying to interpret
Steve French099a58f2005-04-28 22:41:07 -070099oplock breaks as SMB responses). Add ioctl for checking that the
100current uid matches the uid of the mounter (needed by umount.cifs).
101Reduce the number of large buffer allocations in cifs response processing
102(significantly reduces memory pressure under heavy stress with multiple
103processes accessing the same server at the same time).
Steve Frenchf654bac2005-04-28 22:41:04 -0700104
105Version 1.31
106------------
Linus Torvalds1da177e2005-04-16 15:20:36 -0700107Fix updates of DOS attributes and time fields so that files on NT4 servers
108do not get marked delete on close. Display sizes of cifs buffer pools in
109cifs stats. Fix oops in unmount when cifsd thread being killed by
110shutdown. Add generic readv/writev and aio support. Report inode numbers
111consistently in readdir and lookup (when serverino mount option is
112specified use the inode number that the server reports - for both lookup
113and readdir, otherwise by default the locally generated inode number is used
114for inodes created in either path since servers are not always able to
115provide unique inode numbers when exporting multiple volumes from under one
116sharename).
117
118Version 1.30
119------------
120Allow new nouser_xattr mount parm to disable xattr support for user namespace.
121Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
122(mostly affects NT4 servers) by retry with handle based network operation.
123Add new POSIX Query FS Info for returning statfs info more accurately.
124Handle passwords with multiple commas in them.
125
126Version 1.29
127------------
128Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
129Fix capabilities flags for large readx so as to allow reads larger than 64K.
130
131Version 1.28
132------------
133Add module init parm for large SMB buffer size (to allow it to be changed
134from its default of 16K) which is especially useful for large file copy
135when mounting with the directio mount option. Fix oops after
136returning from mount when experimental ExtendedSecurity enabled and
137SpnegoNegotiated returning invalid error. Fix case to retry better when
138peek returns from 1 to 3 bytes on socket which should have more data.
139Fixed path based calls (such as cifs lookup) to handle path names
140longer than 530 (now can handle PATH_MAX). Fix pass through authentication
141from Samba server to DC (Samba required dummy LM password).
142
143Version 1.27
144------------
145Turn off DNOTIFY (directory change notification support) by default
146(unless built with the experimental flag) to fix hang with KDE
147file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
148waiting on an SMB response) in SendReceive when session dies but
149reconnects quickly from another task. Add module init parms for
150minimum number of large and small network buffers in the buffer pools,
151and for the maximum number of simultaneous requests.
152
153Version 1.26
154------------
155Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
156and other POSIX CIFS compliant servers. Fix error mapping for getfacl
157to EOPNOTSUPP when server does not support posix acls on the wire. Fix
158improperly zeroed buffer in CIFS Unix extensions set times call.
159
160Version 1.25
161------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700162Fix internationalization problem in cifs readdir with filenames that map to
Alexey Dobriyan4de151d2006-03-22 00:13:35 +0100163longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
Linus Torvalds1da177e2005-04-16 15:20:36 -0700164for readdir to netapp servers. Fix search rewind (seek into readdir to return
165non-consecutive entries). Do not do readdir when server negotiates
166buffer size to small to fit filename. Add support for reading POSIX ACLs from
167the server (add also acl and noacl mount options).
168
169Version 1.24
170------------
171Optionally allow using server side inode numbers, rather than client generated
172ones by specifying mount option "serverino" - this is required for some apps
173to work which double check hardlinked files and have persistent inode numbers.
174
175Version 1.23
176------------
177Multiple bigendian fixes. On little endian systems (for reconnect after
178network failure) fix tcp session reconnect code so we do not try first
179to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
180as directories rather than symlinks because we can do follow link on them.
181
182Version 1.22
183------------
184Add config option to enable XATTR (extended attribute) support, mapping
185xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
186minor fixes pointed out by the Stanford SWAT checker (mostly missing
187or out of order NULL pointer checks in little used error paths).
188
189Version 1.21
190------------
191Add new mount parm to control whether mode check (generic_permission) is done
192on the client. If Unix extensions are enabled and the uids on the client
193and server do not match, client permission checks are meaningless on
194server uids that do not exist on the client (this does not affect the
195normal ACL check which occurs on the server). Fix default uid
196on mknod to match create and mkdir. Add optional mount parm to allow
197override of the default uid behavior (in which the server sets the uid
198and gid of newly created files). Normally for network filesystem mounts
199user want the server to set the uid/gid on newly created files (rather than
200using uid of the client processes you would in a local filesystem).
201
202Version 1.20
203------------
204Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
205info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
206(in build_wildcard_path_from_dentry). Fix mknod to pass type field
207(block/char/fifo) properly. Remove spurious mount warning log entry when
208credentials passed as mount argument. Set major/minor device number in
209inode for block and char devices when unix extensions enabled.
210
211Version 1.19
212------------
213Fix /proc/fs/cifs/Stats and DebugData display to handle larger
214amounts of return data. Properly limit requests to MAX_REQ (50
215is the usual maximum active multiplex SMB/CIFS requests per server).
216Do not kill cifsd (and thus hurt the other SMB session) when more than one
217session to the same server (but with different userids) exists and one
218of the two user's smb sessions is being removed while leaving the other.
219Do not loop reconnecting in cifsd demultiplex thread when admin
220kills the thread without going through unmount.
221
222Version 1.18
223------------
224Do not rename hardlinked files (since that should be a noop). Flush
225cached write behind data when reopening a file after session abend,
226except when already in write. Grab per socket sem during reconnect
227to avoid oops in sendmsg if overlapping with reconnect. Do not
228reset cached inode file size on readdir for files open for write on
229client.
230
231
232Version 1.17
233------------
234Update number of blocks in file so du command is happier (in Linux a fake
235blocksize of 512 is required for calculating number of blocks in inode).
236Fix prepare write of partial pages to read in data from server if possible.
237Fix race on tcpStatus field between unmount and reconnection code, causing
238cifsd process sometimes to hang around forever. Improve out of memory
239checks in cifs_filldir
240
241Version 1.16
242------------
243Fix incorrect file size in file handle based setattr on big endian hardware.
244Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
245and closing file structs in writepage/partialpagewrite. Add statistics
246for each mounted share (new menuconfig option). Fix endianness problem in
247volume information displayed in /proc/fs/cifs/DebugData (only affects
248affects big endian architectures). Prevent renames while constructing
249path names for open, mkdir and rmdir.
250
251Version 1.15
252------------
253Change to mempools for alloc smb request buffers and multiplex structs
254to better handle low memory problems (and potential deadlocks).
255
256Version 1.14
257------------
258Fix incomplete listings of large directories on Samba servers when Unix
259extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
260rename deadlock when writing out dirty pages at same time.
261
262Version 1.13
263------------
264Fix open of files in which O_CREATE can cause the mode to change in
265some cases. Fix case in which retry of write overlaps file close.
266Fix PPC64 build error. Reduce excessive stack usage in smb password
267hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
268
269Version 1.12
270------------
271Fixes for large file copy, signal handling, socket retry, buffer
272allocation and low memory situations.
273
274Version 1.11
275------------
276Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
277also now allowing support for specifying client netbiosname. NT4 support added.
278
279Version 1.10
280------------
281Fix reconnection (and certain failed mounts) to properly wake up the
282blocked users thread so it does not seem hung (in some cases was blocked
283until the cifs receive timeout expired). Fix spurious error logging
284to kernel log when application with open network files killed.
285
286Version 1.09
287------------
288Fix /proc/fs module unload warning message (that could be logged
289to the kernel log). Fix intermittent failure in connectathon
290test7 (hardlink count not immediately refreshed in case in which
291inode metadata can be incorrectly kept cached when time near zero)
292
293Version 1.08
294------------
295Allow file_mode and dir_mode (specified at mount time) to be enforced
296locally (the server already enforced its own ACLs too) for servers
297that do not report the correct mode (do not support the
298CIFS Unix Extensions).
299
300Version 1.07
301------------
302Fix some small memory leaks in some unmount error paths. Fix major leak
303of cache pages in readpages causing multiple read oriented stress
304testcases (including fsx, and even large file copy) to fail over time.
305
306Version 1.06
307------------
308Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
309This allows files that differ only in case and improves performance of file
310creation and file open to such servers. Fix semaphore conflict which causes
311slow delete of open file to Samba (which unfortunately can cause an oplock
312break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
313
314Version 1.05
315------------
316fixes to cifs_readpages for fsx test case
317
318Version 1.04
319------------
320Fix caching data integrity bug when extending file size especially when no
321oplock on file. Fix spurious logging of valid already parsed mount options
322that are parsed outside of the cifs vfs such as nosuid.
323
324
325Version 1.03
326------------
327Connect to server when port number override not specified, and tcp port
328unitialized. Reset search to restart at correct file when kernel routine
329filldir returns error during large directory searches (readdir).
330
331Version 1.02
332------------
333Fix caching problem when files opened by multiple clients in which
334page cache could contain stale data, and write through did
335not occur often enough while file was still open when read ahead
336(read oplock) not allowed. Treat "sep=" when first mount option
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700337as an override of comma as the default separator between mount
Linus Torvalds1da177e2005-04-16 15:20:36 -0700338options.
339
340Version 1.01
341------------
342Allow passwords longer than 16 bytes. Allow null password string.
343
344Version 1.00
345------------
346Gracefully clean up failed mounts when attempting to mount to servers such as
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700347Windows 98 that terminate tcp sessions during protocol negotiation. Handle
Linus Torvalds1da177e2005-04-16 15:20:36 -0700348embedded commas in mount parsing of passwords.
349
350Version 0.99
351------------
352Invalidate local inode cached pages on oplock break and when last file
353instance is closed so that the client does not continue using stale local
354copy rather than later modified server copy of file. Do not reconnect
355when server drops the tcp session prematurely before negotiate
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700356protocol response. Fix oops in reopen_file when dentry freed. Allow
Linus Torvalds1da177e2005-04-16 15:20:36 -0700357the support for CIFS Unix Extensions to be disabled via proc interface.
358
359Version 0.98
360------------
361Fix hang in commit_write during reconnection of open files under heavy load.
362Fix unload_nls oops in a mount failure path. Serialize writes to same socket
363which also fixes any possible races when cifs signatures are enabled in SMBs
364being sent out of signature sequence number order.
365
366Version 0.97
367------------
368Fix byte range locking bug (endian problem) causing bad offset and
369length.
370
371Version 0.96
372------------
373Fix oops (in send_sig) caused by CIFS unmount code trying to
374wake up the demultiplex thread after it had exited. Do not log
375error on harmless oplock release of closed handle.
376
377Version 0.95
378------------
379Fix unsafe global variable usage and password hash failure on gcc 3.3.1
380Fix problem reconnecting secondary mounts to same server after session
381failure. Fix invalid dentry - race in mkdir when directory gets created
382by another client between the lookup and mkdir.
383
384Version 0.94
385------------
386Fix to list processing in reopen_files. Fix reconnection when server hung
387but tcpip session still alive. Set proper timeout on socket read.
388
389Version 0.93
390------------
391Add missing mount options including iocharset. SMP fixes in write and open.
392Fix errors in reconnecting after TCP session failure. Fix module unloading
393of default nls codepage
394
395Version 0.92
396------------
397Active smb transactions should never go negative (fix double FreeXid). Fix

440Finish support for Linux 2.5 open/create changes, which removes the
441redundant NTCreate/QPathInfo/close that was sent during file create.
442Enable oplock by default. Enable packet signing by default (needed to
443access many recent Windows servers)
444
445Version 0.83
446------------
447Fix oops when mounting to long server names caused by inverted parms to kmalloc.
448Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
449we will choose a cifs user session (smb uid) that better matches the local
450uid if a) the mount uid does not match the current uid and b) we have another
451session to the same server (ip address) for a different mount which

528------------
529Fix oops in get dfs referral (triggered when null path sent in to
530mount). Add support for overriding rsize at mount time.
531
532Version 0.69
533------------
534Fix buffer overrun in readdir which caused intermittent kernel oopses.
535Fix writepage code to release kmap on write data. Allow "-ip=" new
536mount option to be passed in on parameter distinct from the first part
537(server name portion of) the UNC name. Allow override of the
538tcp port of the target server via new mount option "-port="
539
540Version 0.68
541------------
542Fix search handle leak on rewind. Fix setuid and gid so that they are
543reflected in the local inode immediately. Cleanup of whitespace
544to make 2.4 and 2.5 versions more consistent.
545
546
547Version 0.67
548------------
549Fix signal sending so that captive thread (cifsd) exits on umount
550(which was causing the warning in kmem_cache_free of the request buffers
551at rmmod time). This had broken as a sideeffect of the recent global
552kernel change to daemonize. Fix memory leak in readdir code which
553showed up in "ls -R" (and applications that did search rewinding).
554
555Version 0.66
556------------
557Reconnect tids and fids after session reconnection (still do not
558reconnect byte range locks though). Fix problem caching
559lookup information for directory inodes, improving performance,
560especially in deep directory trees. Fix various build warnings.

573
574Version 0.63
575------------
576Fix memory leak in AllocMidQEntry.
577Finish reconnection logic, so connection with server can be dropped
578(or server rebooted) and the cifs client will reconnect.
579
580Version 0.62
581------------
582Fix temporary socket leak when bad userid or password specified
583(or other SMBSessSetup failure). Increase maximum buffer size to slightly

585sizes. Add support for readpages
586
587Version 0.61
588------------
589Fix oops when username not passed in on mount. Extensive fixes and improvements
590to error logging (strip redundant newlines, change debug macros to ensure newline
591passed in and to be more consistent). Fix writepage wrong file handle problem,
592a readonly file handle could be incorrectly used to attempt to write out
593file updates through the page cache to multiply open files. This could cause
594the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
595shares to the same Windows server when using different usernames
596(doing this to Samba servers worked but Windows was rejecting it) - now it is
597possible to use different userids when connecting to the same server from a
598Linux client. Fix oops when treeDisconnect called during unmount on
599previously freed socket.
600
601Version 0.60

614Memory mapped operations now working.
615
616Version 0.57
617------------
618Added writepage code for additional memory mapping support. Fixed leak in xids causing
619the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
620every stat call. Additional formatting cleanup.
621
622Version 0.56
623------------

694
695Version 0.41
696------------
697Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700698files now return the correct number of links on fstat as they are repeatedly linked and unlinked.

726
727Version 0.34
728------------
729Fixed dentry caching bug, misc. cleanup
730
731Version 0.33
732------------
733Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
734on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.

742
743Version 0.31
744------------
7451) Fixed lockrange to be correct (it was one byte too short)
746
7472) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
748show range as locked when there is a conflict with an existing lock.
749
7503) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
751in most cases. Eventually will offer optional ability to query server for the correct perms.
752
7533) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
754but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
755session)
756
7574) Fixed error logging of valid mount options
758
7595) Removed logging of password field.
760
7616) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
762and cleaned them up and made them more consistent with other cifs functions.
763
7647) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700765(with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
Linus Torvalds1da177e2005-04-16 15:20:36 -0700766nor is the symlink support using the Unix extensions
