Steve French3a5ff612006-07-14 22:37:11 +00005Version 1.45
6------------
7Do not time out lockw calls when using posix extensions. Do not
8time out requests if server still responding reasonably fast
Steve Frenche466e482006-08-15 13:07:18 +00009on requests on other threads. Improve POSIX locking emulation,
10(lock cancel now works, and unlock of merged range works even
11to Windows servers now). Fix oops on mount to lanman servers
Steve Frenchea4c07d2006-08-16 19:44:25 +000012(win9x, os/2 etc.) when null password. Do not send listxattr
Steve French2fe87f02006-09-21 07:02:52 +000013(SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
14problem (instantiate inodes/dentries in right order for readdir).

Steve French39798772006-05-31 22:40:51 +000016Version 1.44
17------------
18Rewritten sessionsetup support, including support for legacy SMB
19session setup needed for OS/2 and older servers such as Windows 95 and 98.
Steve French5bafd762006-06-07 00:18:43 +000020Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
21so we can do search (ls etc.) to OS/2. Do not send NTCreateX
22or recent levels of FindFirst unless server says it supports NT SMBs
Steve French1717ffc2006-06-08 05:41:32 +000023(instead use legacy equivalents from LANMAN dialect). Fix to allow
24NTLMv2 authentication support (now can use stronger password hashing
Steve French750d1152006-06-27 06:28:30 +000025on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
26Allow override of global cifs security flags on mount via "sec=" option(s).

Steve Frenchfc94cdb2006-05-30 18:03:32 +000028Version 1.43
29------------
30POSIX locking to servers which support CIFS POSIX Extensions
Steve Frencha878fb22006-05-30 18:04:19 +000031(disabled by default controlled by proc/fs/cifs/Experimental).
32Handle conversion of long share names (especially Asian languages)
Steve French26a21b92006-05-31 18:05:34 +000033to Unicode during mount. Fix memory leak in sess struct on reconnect.
34Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
35cifs open which helps rare case when setpathinfo fails or server does
36not support it.
Steve Frenchfc94cdb2006-05-30 18:03:32 +000037
Steve French13298de2006-03-03 10:45:19 +000038Version 1.42
39------------
40Fix slow oplock break when mounted to different servers at the same time and
Steve French60808232006-04-22 15:53:05 +000041the tids match and we try to find matching fid on wrong server. Fix read
42looping when signing required by server (2.6.16 kernel only). Fix readdir
43vs. rename race which could cause each to hang. Return . and .. even
44if server does not. Allow searches to skip first three entries and
45begin at any location. Fix oops in find_writeable_file.
Steve French13298de2006-03-03 10:45:19 +000046
Steve French12b3b8f2006-02-09 21:12:47 +000047Version 1.41
48------------
49Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
50configure stronger authentication. Fix sfu symlinks so they can
Steve French184ed212006-02-24 06:15:11 +000051be followed (not just recognized). Fix wraparound of bcc on
52read responses when buffer size over 64K and also fix wrap of
53max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
54cifs_user_read and cifs_readpages (when EAGAIN on send of smb
Steve French08547b02006-02-28 22:39:25 +000055on socket is returned over and over). Add POSIX (advisory) byte range
56locking support (requires server with newest CIFS UNIX Extensions
Steve French083d3a22006-03-03 09:53:36 +000057to the protocol implemented). Slow down negprot slightly in port 139
58RFC1001 case to give session_init time on buggy servers.
Steve French12b3b8f2006-02-09 21:12:47 +000059
Steve French83451872005-12-01 17:12:59 -080060Version 1.40
61------------
Steve French84afc292005-12-02 13:32:45 -080062Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
Steve French0a4b92c2006-01-12 15:44:21 -080063of readpages by eliminating one extra memcpy. Allow update of file size
64from remote server even if file is open for write as long as mount is
Steve Frencheeac8042006-01-13 21:34:58 -080065directio. Recognize share mode security and send NTLM encrypted password
66on tree connect if share mode negotiated.
Steve French83451872005-12-01 17:12:59 -080067
Steve French23e7dd72005-10-20 13:44:56 -070068Version 1.39
69------------
Steve French3abb9272005-11-28 08:16:13 -080070Defer close of a file handle slightly if pending writes depend on that handle
Steve French23e7dd72005-10-20 13:44:56 -070071(this reduces the EBADF bad file handle errors that can be logged under heavy
Steve French3c50c612005-11-10 17:31:33 -080072stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
Steve French3abb9272005-11-28 08:16:13 -080073Fix SFU style symlinks and mknod needed for servers which do not support the
74CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
75dentries so files that the client sees as deleted but that later get created
Steve French6473a552005-11-29 20:20:10 -080076on the server will be recognized. Add client side permission check on setattr.
Steve French83451872005-12-01 17:12:59 -080077Timeout stuck requests better (where server has never responded or sent corrupt
78responses)
Steve French23e7dd72005-10-20 13:44:56 -070079
Steve French190fdeb2005-10-10 11:48:26 -070080Version 1.38
81------------
82Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
83to be smaller at first (but increasing) so large write performance performance
84over GigE is better. Do not hang thread on illegal byte range lock response
85from Windows (Windows can send an RFC1001 size which does not match smb size) by
86allowing an SMBs TCP length to be up to a few bytes longer than it should be.
87wsize and rsize can now be larger than negotiated buffer size if server
88supports large readx/writex, even when directio mount flag not specified.
89Write size will in many cases now be 16K instead of 4K which greatly helps
Steve French4ca9c192005-10-10 19:52:13 -070090file copy performance on lightly loaded networks. Fix oops in dnotify
Steve French1047abc2005-10-11 19:58:06 -070091when experimental config flag enabled. Make cifsFYI more granular.
Steve French190fdeb2005-10-10 11:48:26 -070092
Steve Frencheafe8702005-09-15 21:47:30 -070093Version 1.37
94------------
95Fix readdir caching when unlink removes file in current search buffer,
96and this is followed by a rewind search to just before the deleted entry.
Steve Frenche30dcf32005-09-20 20:49:16 -070097Do not attempt to set ctime unless atime and/or mtime change requested
Steve French20962432005-09-21 22:05:57 -070098(most servers throw it away anyway). Fix length check of received smbs
Steve French70ca7342005-09-22 16:32:06 -070099to be more accurate. Fix big endian problem with mapchars mount option,
100and with a field returned by statfs.
Steve Frencheafe8702005-09-15 21:47:30 -0700101
Steve Frenchc46fa8a2005-08-18 20:49:57 -0700102Version 1.36
103------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700104Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
Steve French6b8edfe2005-08-23 20:26:03 -0700105For these older servers, add option for passing netbios name of server in
Steve French16abbec2005-08-30 13:10:14 -0700106on mount (servernetbiosname). Add suspend support for power management, to
107avoid cifsd thread preventing software suspend from working.
Steve Frenchc46fa8a2005-08-18 20:49:57 -0700108Add mount option for disabling the default behavior of sending byte range lock
109requests to the server (necessary for certain applications which break with
110mandatory lock behavior such as Evolution), and also mount option for
111requesting case insensitive matching for path based requests (requesting
112case sensitive is the default).
113
Steve Frenchf4cfd692005-07-14 18:29:02 -0500114Version 1.35
115------------
116Add writepage performance improvements. Fix path name conversions
117for long filenames on mounts which were done with "mapchars" mount option
Steve Frencha10faeb22005-08-22 21:38:31 -0700118specified. Ensure multiplex ids do not collide. Fix case in which
119rmmod can oops if done soon after last unmount. Fix truncated
120search (readdir) output when resume filename was a long filename.
121Fix filename conversion when mapchars mount option was specified and
122filename was a long filename.
Steve Frenchf4cfd692005-07-14 18:29:02 -0500123
Steve French11aa0142005-04-28 22:41:10 -0700124Version 1.34
125------------
126Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
Steve French31ca3bc2005-04-28 22:41:11 -0700127Do not oops if root user kills cifs oplock kernel thread or
128kills the cifsd thread (NB: killing the cifs kernel threads is not
129recommended, unmount and rmmod cifs will kill them when they are
Steve French68575472005-04-30 11:10:57 -0700130no longer needed). Fix readdir to ASCII servers (ie older servers
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700131which do not support Unicode) and also require asterisk.
Steve French3079ca62005-06-09 14:44:07 -0700132Fix out of memory case in which data could be written one page
133off in the page cache.
Steve French11aa0142005-04-28 22:41:10 -0700134
Steve French966ca922005-04-28 22:41:08 -0700135Version 1.33
136------------
137Fix caching problem, in which readdir of directory containing a file
138which was cached could cause the file's time stamp to be updated
139without invalidating the readahead data (so we could get stale
140file data on the client for that file even as the server copy changed).
Steve Frenchcd634992005-04-28 22:41:10 -0700141Cleanup response processing so cifsd can not loop when abnormally
142terminated.
Steve French966ca922005-04-28 22:41:08 -0700143
144
Steve Frenchf654bac2005-04-28 22:41:04 -0700145Version 1.32
Linus Torvalds1da177e2005-04-16 15:20:36 -0700146------------
147Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
148transact response for an SMB request and search entry split across two frames.
Steve Frenchf654bac2005-04-28 22:41:04 -0700149Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
150as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
151unless server explicitly claims to support them in CIFS Unix extensions
Steve Frenchad009ac2005-04-28 22:41:05 -0700152POSIX ACL capability bit. Fix packet signing when multiuser mounting with
Steve Frenchcbe04762005-04-28 22:41:05 -0700153different users from the same client to the same server. Fix oops in
Steve French6a0b4822005-04-28 22:41:05 -0700154cifs_close. Add mount option for remapping reserved characters in
155filenames (also allow recognizing files with created by SFU which have any
Steve French737b7582005-04-28 22:41:06 -0700156of these seven reserved characters, except backslash, to be recognized).
Steve French848f3fc2005-04-28 22:41:07 -0700157Fix invalid transact2 message (we were sometimes trying to interpret
Steve French099a58f2005-04-28 22:41:07 -0700158oplock breaks as SMB responses). Add ioctl for checking that the
159current uid matches the uid of the mounter (needed by umount.cifs).
160Reduce the number of large buffer allocations in cifs response processing
161(significantly reduces memory pressure under heavy stress with multiple
162processes accessing the same server at the same time).
Steve Frenchf654bac2005-04-28 22:41:04 -0700163
164Version 1.31
165------------
Linus Torvalds1da177e2005-04-16 15:20:36 -0700166Fix updates of DOS attributes and time fields so that files on NT4 servers
167do not get marked delete on close. Display sizes of cifs buffer pools in
168cifs stats. Fix oops in unmount when cifsd thread being killed by
169shutdown. Add generic readv/writev and aio support. Report inode numbers
170consistently in readdir and lookup (when serverino mount option is
171specified use the inode number that the server reports - for both lookup
172and readdir, otherwise by default the locally generated inode number is used
173for inodes created in either path since servers are not always able to
174provide unique inode numbers when exporting multiple volumes from under one
175sharename).
176
177Version 1.30
178------------
179Allow new nouser_xattr mount parm to disable xattr support for user namespace.
180Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
181(mostly affects NT4 servers) by retry with handle based network operation.
182Add new POSIX Query FS Info for returning statfs info more accurately.
183Handle passwords with multiple commas in them.
184
185Version 1.29
186------------
187Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
188Fix capabilities flags for large readx so as to allow reads larger than 64K.
189
190Version 1.28
191------------
192Add module init parm for large SMB buffer size (to allow it to be changed
193from its default of 16K) which is especially useful for large file copy
194when mounting with the directio mount option. Fix oops after
195returning from mount when experimental ExtendedSecurity enabled and
196SpnegoNegotiated returning invalid error. Fix case to retry better when
197peek returns from 1 to 3 bytes on socket which should have more data.
198Fixed path based calls (such as cifs lookup) to handle path names
199longer than 530 (now can handle PATH_MAX). Fix pass through authentication
200from Samba server to DC (Samba required dummy LM password).
201
202Version 1.27
203------------
204Turn off DNOTIFY (directory change notification support) by default
205(unless built with the experimental flag) to fix hang with KDE
206file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
207waiting on an SMB response) in SendReceive when session dies but
208reconnects quickly from another task. Add module init parms for
209minimum number of large and small network buffers in the buffer pools,
210and for the maximum number of simultaneous requests.
211
212Version 1.26
213------------
214Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
215and other POSIX CIFS compliant servers. Fix error mapping for getfacl
216to EOPNOTSUPP when server does not support posix acls on the wire. Fix
217improperly zeroed buffer in CIFS Unix extensions set times call.
218
219Version 1.25
220------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700221Fix internationalization problem in cifs readdir with filenames that map to
Alexey Dobriyan4de151d2006-03-22 00:13:35 +0100222longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
Linus Torvalds1da177e2005-04-16 15:20:36 -0700223for readdir to netapp servers. Fix search rewind (seek into readdir to return
224non-consecutive entries). Do not do readdir when server negotiates
225buffer size to small to fit filename. Add support for reading POSIX ACLs from
226the server (add also acl and noacl mount options).
227
228Version 1.24
229------------
230Optionally allow using server side inode numbers, rather than client generated
231ones by specifying mount option "serverino" - this is required for some apps
232to work which double check hardlinked files and have persistent inode numbers.
233
234Version 1.23
235------------
236Multiple bigendian fixes. On little endian systems (for reconnect after
237network failure) fix tcp session reconnect code so we do not try first
238to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
239as directories rather than symlinks because we can do follow link on them.
240
241Version 1.22
242------------
243Add config option to enable XATTR (extended attribute) support, mapping
244xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
245minor fixes pointed out by the Stanford SWAT checker (mostly missing
246or out of order NULL pointer checks in little used error paths).
247
248Version 1.21
249------------
250Add new mount parm to control whether mode check (generic_permission) is done
251on the client. If Unix extensions are enabled and the uids on the client
252and server do not match, client permission checks are meaningless on
253server uids that do not exist on the client (this does not affect the
254normal ACL check which occurs on the server). Fix default uid
255on mknod to match create and mkdir. Add optional mount parm to allow
256override of the default uid behavior (in which the server sets the uid
257and gid of newly created files). Normally for network filesystem mounts
258user want the server to set the uid/gid on newly created files (rather than
259using uid of the client processes you would in a local filesystem).
260
261Version 1.20
262------------
263Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
264info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
265(in build_wildcard_path_from_dentry). Fix mknod to pass type field
266(block/char/fifo) properly. Remove spurious mount warning log entry when
267credentials passed as mount argument. Set major/minor device number in
268inode for block and char devices when unix extensions enabled.
269
270Version 1.19
271------------
272Fix /proc/fs/cifs/Stats and DebugData display to handle larger
273amounts of return data. Properly limit requests to MAX_REQ (50
274is the usual maximum active multiplex SMB/CIFS requests per server).
275Do not kill cifsd (and thus hurt the other SMB session) when more than one
276session to the same server (but with different userids) exists and one
277of the two user's smb sessions is being removed while leaving the other.
278Do not loop reconnecting in cifsd demultiplex thread when admin
279kills the thread without going through unmount.
280
281Version 1.18
282------------
283Do not rename hardlinked files (since that should be a noop). Flush
284cached write behind data when reopening a file after session abend,
285except when already in write. Grab per socket sem during reconnect
286to avoid oops in sendmsg if overlapping with reconnect. Do not
287reset cached inode file size on readdir for files open for write on
288client.
289
290
291Version 1.17
292------------
293Update number of blocks in file so du command is happier (in Linux a fake
294blocksize of 512 is required for calculating number of blocks in inode).
295Fix prepare write of partial pages to read in data from server if possible.
296Fix race on tcpStatus field between unmount and reconnection code, causing
297cifsd process sometimes to hang around forever. Improve out of memory
298checks in cifs_filldir
299
300Version 1.16
301------------
302Fix incorrect file size in file handle based setattr on big endian hardware.
303Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
304and closing file structs in writepage/partialpagewrite. Add statistics
305for each mounted share (new menuconfig option). Fix endianness problem in
306volume information displayed in /proc/fs/cifs/DebugData (only affects
307affects big endian architectures). Prevent renames while constructing
308path names for open, mkdir and rmdir.
309
310Version 1.15
311------------
312Change to mempools for alloc smb request buffers and multiplex structs
313to better handle low memory problems (and potential deadlocks).
314
315Version 1.14
316------------
317Fix incomplete listings of large directories on Samba servers when Unix
318extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
319rename deadlock when writing out dirty pages at same time.
320
321Version 1.13
322------------
323Fix open of files in which O_CREATE can cause the mode to change in
324some cases. Fix case in which retry of write overlaps file close.
325Fix PPC64 build error. Reduce excessive stack usage in smb password
326hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
327
328Version 1.12
329------------
330Fixes for large file copy, signal handling, socket retry, buffer
331allocation and low memory situations.
332
333Version 1.11
334------------
335Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
336also now allowing support for specifying client netbiosname. NT4 support added.
337
338Version 1.10
339------------
340Fix reconnection (and certain failed mounts) to properly wake up the
341blocked users thread so it does not seem hung (in some cases was blocked
342until the cifs receive timeout expired). Fix spurious error logging
343to kernel log when application with open network files killed.
344
345Version 1.09
346------------
347Fix /proc/fs module unload warning message (that could be logged
348to the kernel log). Fix intermittent failure in connectathon
349test7 (hardlink count not immediately refreshed in case in which
350inode metadata can be incorrectly kept cached when time near zero)
351
352Version 1.08
353------------
354Allow file_mode and dir_mode (specified at mount time) to be enforced
355locally (the server already enforced its own ACLs too) for servers
356that do not report the correct mode (do not support the
357CIFS Unix Extensions).
358
359Version 1.07
360------------

364
365Version 1.06
366------------
367Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
368This allows files that differ only in case and improves performance of file
369creation and file open to such servers. Fix semaphore conflict which causes
370slow delete of open file to Samba (which unfortunately can cause an oplock
371break to self while vfs_unlink held i_sem) which can hang for 20 seconds.

393page cache could contain stale data, and write through did
394not occur often enough while file was still open when read ahead
395(read oplock) not allowed. Treat "sep=" when first mount option
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700396as an override of comma as the default separator between mount
Linus Torvalds1da177e2005-04-16 15:20:36 -0700397options.

408
409Version 0.99
410------------
411Invalidate local inode cached pages on oplock break and when last file
412instance is closed so that the client does not continue using stale local
413copy rather than later modified server copy of file. Do not reconnect
414when server drops the tcp session prematurely before negotiate
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700415protocol response. Fix oops in reopen_file when dentry freed. Allow

501Enable oplock by default. Enable packet signing by default (needed to
502access many recent Windows servers)
503
504Version 0.83
505------------
506Fix oops when mounting to long server names caused by inverted parms to kmalloc.
507Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
508we will choose a cifs user session (smb uid) that better matches the local

590
591Version 0.69
592------------
593Fix buffer overrun in readdir which caused intermittent kernel oopses.
594Fix writepage code to release kmap on write data. Allow "-ip=" new
595mount option to be passed in on parameter distinct from the first part
596(server name portion of) the UNC name. Allow override of the
597tcp port of the target server via new mount option "-port="
598
599Version 0.68
600------------
601Fix search handle leak on rewind. Fix setuid and gid so that they are
602reflected in the local inode immediately. Cleanup of whitespace
603to make 2.4 and 2.5 versions more consistent.
604
605
606Version 0.67
607------------
608Fix signal sending so that captive thread (cifsd) exits on umount
609(which was causing the warning in kmem_cache_free of the request buffers
610at rmmod time). This had broken as a sideeffect of the recent global
611kernel change to daemonize. Fix memory leak in readdir code which
612showed up in "ls -R" (and applications that did search rewinding).
613
614Version 0.66

632
633Version 0.63
634------------
635Fix memory leak in AllocMidQEntry.
636Finish reconnection logic, so connection with server can be dropped

640------------
641Fix temporary socket leak when bad userid or password specified
642(or other SMBSessSetup failure). Increase maximum buffer size to slightly

647------------
648Fix oops when username not passed in on mount. Extensive fixes and improvements
649to error logging (strip redundant newlines, change debug macros to ensure newline
650passed in and to be more consistent). Fix writepage wrong file handle problem,
651a readonly file handle could be incorrectly used to attempt to write out
652file updates through the page cache to multiply open files. This could cause
653the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
654shares to the same Windows server when using different usernames
655(doing this to Samba servers worked but Windows was rejecting it) - now it is
656possible to use different userids when connecting to the same server from a
657Linux client. Fix oops when treeDisconnect called during unmount on
658previously freed socket.
659
660Version 0.60

674
675Version 0.57
676------------
677Added writepage code for additional memory mapping support. Fixed leak in xids causing

801
802Version 0.31
803------------
8041) Fixed lockrange to be correct (it was one byte too short)
805
8062) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
807show range as locked when there is a conflict with an existing lock.
808
8093) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
810in most cases. Eventually will offer optional ability to query server for the correct perms.

8123) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
813but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
814session)
815
8164) Fixed error logging of valid mount options
817
8185) Removed logging of password field.
819
8206) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
821and cleaned them up and made them more consistent with other cifs functions.
822
8237) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700824(with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
Linus Torvalds1da177e2005-04-16 15:20:36 -0700825nor is the symlink support using the Unix extensions
