2------------
3Fix mtime bouncing around from local idea of last write times to remote time.
4Fix hang (in i_size_read) when simultaneous size update of same remote file
Steve French8a236262007-03-06 00:31:00 +00005on smp system corrupts sequence number. Do not reread unnecessarily partial page
6(which we are about to overwrite anyway) when writing out file opened rw.

9------------
10Fix oops in list_del during mount caused by unaligned string.
Steve French595dcfe2007-02-08 18:11:42 +000011Fix file corruption which could occur on some large file
12copies caused by writepages page i/o completion bug.
Steve Frencha8507902007-02-06 20:43:30 +000013Seek to SEEK_END forces check for update of file size for non-cached
Steve French8af18972007-02-14 04:42:51 +000014files. Allow file size to be updated on remote extend of locally open,
15non-cached file. Fix reconnect to newer Samba servers (or other servers
16which support the CIFS Unix/POSIX extensions) so that we again tell the
17server the Unix/POSIX cifs capabilities which we support (SetFSInfo).
18Add experimental support for new POSIX Open/Mkdir (which returns
19stat information on the open, and allows setting the mode).

Steve French2fe87f02006-09-21 07:02:52 +000021Version 1.46
22------------
23Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
Steve French4b952a92006-10-30 21:46:13 +000024Allow null user to be specified on mount ("username="). Do not return
25EINVAL on readdir when filldir fails due to overwritten blocksize
Steve French8e87d4d2006-11-02 03:45:24 +000026(fixes FC problem). Return error in rename 2nd attempt retry (ie report
27if rename by handle also fails, after rename by path fails, we were
Steve French33ec32f2006-12-08 04:14:28 +000028not reporting whether the retry worked or not). Fix NTLMv2 to
29work to Windows servers (mount with option "sec=ntlmv2").
Steve French2fe87f02006-09-21 07:02:52 +000030
Steve French3a5ff612006-07-14 22:37:11 +000031Version 1.45
32------------
33Do not time out lockw calls when using posix extensions. Do not
34time out requests if server still responding reasonably fast
Steve Frenche466e482006-08-15 13:07:18 +000035on requests on other threads. Improve POSIX locking emulation,
36(lock cancel now works, and unlock of merged range works even
37to Windows servers now). Fix oops on mount to lanman servers
Steve Frenchea4c07d2006-08-16 19:44:25 +000038(win9x, os/2 etc.) when null password. Do not send listxattr
Steve French2fe87f02006-09-21 07:02:52 +000039(SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
40problem (instantiate inodes/dentries in right order for readdir).
Steve French3a5ff612006-07-14 22:37:11 +000041
Steve French39798772006-05-31 22:40:51 +000042Version 1.44
43------------
44Rewritten sessionsetup support, including support for legacy SMB
45session setup needed for OS/2 and older servers such as Windows 95 and 98.
Steve French5bafd762006-06-07 00:18:43 +000046Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
47so we can do search (ls etc.) to OS/2. Do not send NTCreateX
48or recent levels of FindFirst unless server says it supports NT SMBs
Steve French1717ffc2006-06-08 05:41:32 +000049(instead use legacy equivalents from LANMAN dialect). Fix to allow
50NTLMv2 authentication support (now can use stronger password hashing
Steve French750d1152006-06-27 06:28:30 +000051on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
52Allow override of global cifs security flags on mount via "sec=" option(s).
Steve French39798772006-05-31 22:40:51 +000053
Steve Frenchfc94cdb2006-05-30 18:03:32 +000054Version 1.43
55------------
56POSIX locking to servers which support CIFS POSIX Extensions
Steve Frencha878fb22006-05-30 18:04:19 +000057(disabled by default controlled by proc/fs/cifs/Experimental).
58Handle conversion of long share names (especially Asian languages)
Steve French26a21b92006-05-31 18:05:34 +000059to Unicode during mount. Fix memory leak in sess struct on reconnect.
60Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
61cifs open which helps rare case when setpathinfo fails or server does
62not support it.
Steve Frenchfc94cdb2006-05-30 18:03:32 +000063
Steve French13298de2006-03-03 10:45:19 +000064Version 1.42
65------------
66Fix slow oplock break when mounted to different servers at the same time and
Steve French60808232006-04-22 15:53:05 +000067the tids match and we try to find matching fid on wrong server. Fix read
68looping when signing required by server (2.6.16 kernel only). Fix readdir
69vs. rename race which could cause each to hang. Return . and .. even
70if server does not. Allow searches to skip first three entries and
71begin at any location. Fix oops in find_writeable_file.
Steve French13298de2006-03-03 10:45:19 +000072
Steve French12b3b8f2006-02-09 21:12:47 +000073Version 1.41
74------------
75Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
76configure stronger authentication. Fix sfu symlinks so they can
Steve French184ed212006-02-24 06:15:11 +000077be followed (not just recognized). Fix wraparound of bcc on
78read responses when buffer size over 64K and also fix wrap of
79max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
80cifs_user_read and cifs_readpages (when EAGAIN on send of smb
Steve French08547b02006-02-28 22:39:25 +000081on socket is returned over and over). Add POSIX (advisory) byte range
82locking support (requires server with newest CIFS UNIX Extensions
Steve French083d3a22006-03-03 09:53:36 +000083to the protocol implemented). Slow down negprot slightly in port 139
84RFC1001 case to give session_init time on buggy servers.
Steve French12b3b8f2006-02-09 21:12:47 +000085
Steve French83451872005-12-01 17:12:59 -080086Version 1.40
87------------
Steve French84afc292005-12-02 13:32:45 -080088Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
Steve French0a4b92c2006-01-12 15:44:21 -080089of readpages by eliminating one extra memcpy. Allow update of file size
90from remote server even if file is open for write as long as mount is
Steve Frencheeac8042006-01-13 21:34:58 -080091directio. Recognize share mode security and send NTLM encrypted password
92on tree connect if share mode negotiated.
Steve French83451872005-12-01 17:12:59 -080093
Steve French23e7dd72005-10-20 13:44:56 -070094Version 1.39
95------------
Steve French3abb9272005-11-28 08:16:13 -080096Defer close of a file handle slightly if pending writes depend on that handle
Steve French23e7dd72005-10-20 13:44:56 -070097(this reduces the EBADF bad file handle errors that can be logged under heavy
Steve French3c50c612005-11-10 17:31:33 -080098stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
Steve French3abb9272005-11-28 08:16:13 -080099Fix SFU style symlinks and mknod needed for servers which do not support the
100CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
101dentries so files that the client sees as deleted but that later get created
Steve French6473a552005-11-29 20:20:10 -0800102on the server will be recognized. Add client side permission check on setattr.
Steve French83451872005-12-01 17:12:59 -0800103Timeout stuck requests better (where server has never responded or sent corrupt
104responses)
Steve French23e7dd72005-10-20 13:44:56 -0700105
Steve French190fdeb2005-10-10 11:48:26 -0700106Version 1.38
107------------
108Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
109to be smaller at first (but increasing) so large write performance performance
110over GigE is better. Do not hang thread on illegal byte range lock response
111from Windows (Windows can send an RFC1001 size which does not match smb size) by
112allowing an SMBs TCP length to be up to a few bytes longer than it should be.
113wsize and rsize can now be larger than negotiated buffer size if server
114supports large readx/writex, even when directio mount flag not specified.
115Write size will in many cases now be 16K instead of 4K which greatly helps
Steve French4ca9c192005-10-10 19:52:13 -0700116file copy performance on lightly loaded networks. Fix oops in dnotify
Steve French1047abc2005-10-11 19:58:06 -0700117when experimental config flag enabled. Make cifsFYI more granular.
Steve French190fdeb2005-10-10 11:48:26 -0700118
Steve Frencheafe8702005-09-15 21:47:30 -0700119Version 1.37
120------------
121Fix readdir caching when unlink removes file in current search buffer,
122and this is followed by a rewind search to just before the deleted entry.
Steve Frenche30dcf32005-09-20 20:49:16 -0700123Do not attempt to set ctime unless atime and/or mtime change requested
Steve French20962432005-09-21 22:05:57 -0700124(most servers throw it away anyway). Fix length check of received smbs
Steve French70ca7342005-09-22 16:32:06 -0700125to be more accurate. Fix big endian problem with mapchars mount option,
126and with a field returned by statfs.
Steve Frencheafe8702005-09-15 21:47:30 -0700127
Steve Frenchc46fa8a2005-08-18 20:49:57 -0700128Version 1.36
129------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700130Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
Steve French6b8edfe2005-08-23 20:26:03 -0700131For these older servers, add option for passing netbios name of server in
Steve French16abbec2005-08-30 13:10:14 -0700132on mount (servernetbiosname). Add suspend support for power management, to
133avoid cifsd thread preventing software suspend from working.
Steve Frenchc46fa8a2005-08-18 20:49:57 -0700134Add mount option for disabling the default behavior of sending byte range lock
135requests to the server (necessary for certain applications which break with
136mandatory lock behavior such as Evolution), and also mount option for
137requesting case insensitive matching for path based requests (requesting
138case sensitive is the default).
139
Steve Frenchf4cfd692005-07-14 18:29:02 -0500140Version 1.35
141------------
142Add writepage performance improvements. Fix path name conversions
143for long filenames on mounts which were done with "mapchars" mount option
Steve Frencha10faeb22005-08-22 21:38:31 -0700144specified. Ensure multiplex ids do not collide. Fix case in which
145rmmod can oops if done soon after last unmount. Fix truncated
146search (readdir) output when resume filename was a long filename.
147Fix filename conversion when mapchars mount option was specified and
148filename was a long filename.
Steve Frenchf4cfd692005-07-14 18:29:02 -0500149
Steve French11aa0142005-04-28 22:41:10 -0700150Version 1.34
151------------
152Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
Steve French31ca3bc2005-04-28 22:41:11 -0700153Do not oops if root user kills cifs oplock kernel thread or
154kills the cifsd thread (NB: killing the cifs kernel threads is not
155recommended, unmount and rmmod cifs will kill them when they are
Steve French68575472005-04-30 11:10:57 -0700156no longer needed). Fix readdir to ASCII servers (ie older servers
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700157which do not support Unicode) and also require asterisk.
Steve French3079ca62005-06-09 14:44:07 -0700158Fix out of memory case in which data could be written one page
159off in the page cache.
Steve French11aa0142005-04-28 22:41:10 -0700160
Steve French966ca922005-04-28 22:41:08 -0700161Version 1.33
162------------
163Fix caching problem, in which readdir of directory containing a file
164which was cached could cause the file's time stamp to be updated
165without invalidating the readahead data (so we could get stale
166file data on the client for that file even as the server copy changed).
Steve Frenchcd634992005-04-28 22:41:10 -0700167Cleanup response processing so cifsd can not loop when abnormally
168terminated.
Steve French966ca922005-04-28 22:41:08 -0700169
170
Steve Frenchf654bac2005-04-28 22:41:04 -0700171Version 1.32
Linus Torvalds1da177e2005-04-16 15:20:36 -0700172------------
173Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
174transact response for an SMB request and search entry split across two frames.
Steve Frenchf654bac2005-04-28 22:41:04 -0700175Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
176as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
177unless server explicitly claims to support them in CIFS Unix extensions
Steve Frenchad009ac2005-04-28 22:41:05 -0700178POSIX ACL capability bit. Fix packet signing when multiuser mounting with
Steve Frenchcbe04762005-04-28 22:41:05 -0700179different users from the same client to the same server. Fix oops in
Steve French6a0b4822005-04-28 22:41:05 -0700180cifs_close. Add mount option for remapping reserved characters in
181filenames (also allow recognizing files with created by SFU which have any
Steve French737b7582005-04-28 22:41:06 -0700182of these seven reserved characters, except backslash, to be recognized).
Steve French848f3fc2005-04-28 22:41:07 -0700183Fix invalid transact2 message (we were sometimes trying to interpret
Steve French099a58f2005-04-28 22:41:07 -0700184oplock breaks as SMB responses). Add ioctl for checking that the
185current uid matches the uid of the mounter (needed by umount.cifs).
186Reduce the number of large buffer allocations in cifs response processing
187(significantly reduces memory pressure under heavy stress with multiple
188processes accessing the same server at the same time).
Steve Frenchf654bac2005-04-28 22:41:04 -0700189
190Version 1.31
191------------
Linus Torvalds1da177e2005-04-16 15:20:36 -0700192Fix updates of DOS attributes and time fields so that files on NT4 servers
193do not get marked delete on close. Display sizes of cifs buffer pools in
194cifs stats. Fix oops in unmount when cifsd thread being killed by
195shutdown. Add generic readv/writev and aio support. Report inode numbers
196consistently in readdir and lookup (when serverino mount option is
197specified use the inode number that the server reports - for both lookup
198and readdir, otherwise by default the locally generated inode number is used
199for inodes created in either path since servers are not always able to
200provide unique inode numbers when exporting multiple volumes from under one
201sharename).
202
203Version 1.30
204------------
205Allow new nouser_xattr mount parm to disable xattr support for user namespace.
206Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
207(mostly affects NT4 servers) by retry with handle based network operation.
208Add new POSIX Query FS Info for returning statfs info more accurately.
209Handle passwords with multiple commas in them.
210
211Version 1.29
212------------
213Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
214Fix capabilities flags for large readx so as to allow reads larger than 64K.
215
216Version 1.28
217------------
218Add module init parm for large SMB buffer size (to allow it to be changed
219from its default of 16K) which is especially useful for large file copy
220when mounting with the directio mount option. Fix oops after
221returning from mount when experimental ExtendedSecurity enabled and
222SpnegoNegotiated returning invalid error. Fix case to retry better when
223peek returns from 1 to 3 bytes on socket which should have more data.
224Fixed path based calls (such as cifs lookup) to handle path names
225longer than 530 (now can handle PATH_MAX). Fix pass through authentication
226from Samba server to DC (Samba required dummy LM password).
227
228Version 1.27
229------------
230Turn off DNOTIFY (directory change notification support) by default
231(unless built with the experimental flag) to fix hang with KDE
232file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
233waiting on an SMB response) in SendReceive when session dies but
234reconnects quickly from another task. Add module init parms for
235minimum number of large and small network buffers in the buffer pools,
236and for the maximum number of simultaneous requests.
237
238Version 1.26
239------------
240Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
241and other POSIX CIFS compliant servers. Fix error mapping for getfacl
242to EOPNOTSUPP when server does not support posix acls on the wire. Fix
243improperly zeroed buffer in CIFS Unix extensions set times call.
244
245Version 1.25
246------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700247Fix internationalization problem in cifs readdir with filenames that map to
Alexey Dobriyan4de151d2006-03-22 00:13:35 +0100248longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
Linus Torvalds1da177e2005-04-16 15:20:36 -0700249for readdir to netapp servers. Fix search rewind (seek into readdir to return
250non-consecutive entries). Do not do readdir when server negotiates
251buffer size to small to fit filename. Add support for reading POSIX ACLs from
252the server (add also acl and noacl mount options).
253
254Version 1.24
255------------
256Optionally allow using server side inode numbers, rather than client generated
257ones by specifying mount option "serverino" - this is required for some apps
258to work which double check hardlinked files and have persistent inode numbers.
259
260Version 1.23
261------------
262Multiple bigendian fixes. On little endian systems (for reconnect after
263network failure) fix tcp session reconnect code so we do not try first
264to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
265as directories rather than symlinks because we can do follow link on them.
266
267Version 1.22
268------------
269Add config option to enable XATTR (extended attribute) support, mapping
270xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
271minor fixes pointed out by the Stanford SWAT checker (mostly missing
272or out of order NULL pointer checks in little used error paths).
273
274Version 1.21
275------------
276Add new mount parm to control whether mode check (generic_permission) is done
277on the client. If Unix extensions are enabled and the uids on the client
278and server do not match, client permission checks are meaningless on
279server uids that do not exist on the client (this does not affect the
280normal ACL check which occurs on the server). Fix default uid
281on mknod to match create and mkdir. Add optional mount parm to allow
282override of the default uid behavior (in which the server sets the uid
283and gid of newly created files). Normally for network filesystem mounts
284user want the server to set the uid/gid on newly created files (rather than
285using uid of the client processes you would in a local filesystem).
286
287Version 1.20
288------------
289Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
290info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
291(in build_wildcard_path_from_dentry). Fix mknod to pass type field
292(block/char/fifo) properly. Remove spurious mount warning log entry when
293credentials passed as mount argument. Set major/minor device number in
294inode for block and char devices when unix extensions enabled.
295
296Version 1.19
297------------
298Fix /proc/fs/cifs/Stats and DebugData display to handle larger
299amounts of return data. Properly limit requests to MAX_REQ (50
300is the usual maximum active multiplex SMB/CIFS requests per server).
301Do not kill cifsd (and thus hurt the other SMB session) when more than one
302session to the same server (but with different userids) exists and one
303of the two user's smb sessions is being removed while leaving the other.
304Do not loop reconnecting in cifsd demultiplex thread when admin
305kills the thread without going through unmount.
306
307Version 1.18
308------------
309Do not rename hardlinked files (since that should be a noop). Flush
310cached write behind data when reopening a file after session abend,
311except when already in write. Grab per socket sem during reconnect
312to avoid oops in sendmsg if overlapping with reconnect. Do not
313reset cached inode file size on readdir for files open for write on
314client.
315
316
317Version 1.17
318------------
319Update number of blocks in file so du command is happier (in Linux a fake
320blocksize of 512 is required for calculating number of blocks in inode).
321Fix prepare write of partial pages to read in data from server if possible.
322Fix race on tcpStatus field between unmount and reconnection code, causing
323cifsd process sometimes to hang around forever. Improve out of memory
324checks in cifs_filldir
325
326Version 1.16
327------------

419page cache could contain stale data, and write through did
420not occur often enough while file was still open when read ahead
421(read oplock) not allowed. Treat "sep=" when first mount option
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700422as an override of comma as the default separator between mount
Linus Torvalds1da177e2005-04-16 15:20:36 -0700423options.

434
435Version 0.99
436------------
437Invalidate local inode cached pages on oplock break and when last file
438instance is closed so that the client does not continue using stale local
439copy rather than later modified server copy of file. Do not reconnect
440when server drops the tcp session prematurely before negotiate
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700441protocol response. Fix oops in reopen_file when dentry freed. Allow

530Version 0.83
531------------
532Fix oops when mounting to long server names caused by inverted parms to kmalloc.
533Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
534we will choose a cifs user session (smb uid) that better matches the local

616
617Version 0.69
618------------
619Fix buffer overrun in readdir which caused intermittent kernel oopses.
620Fix writepage code to release kmap on write data. Allow "-ip=" new
621mount option to be passed in on parameter distinct from the first part
622(server name portion of) the UNC name. Allow override of the
623tcp port of the target server via new mount option "-port="
624
625Version 0.68
626------------

630
631
632Version 0.67
633------------
634Fix signal sending so that captive thread (cifsd) exits on umount
635(which was causing the warning in kmem_cache_free of the request buffers
636at rmmod time). This had broken as a sideeffect of the recent global
637kernel change to daemonize. Fix memory leak in readdir code which
638showed up in "ls -R" (and applications that did search rewinding).

666------------
667Fix temporary socket leak when bad userid or password specified
668(or other SMBSessSetup failure). Increase maximum buffer size to slightly

673------------
674Fix oops when username not passed in on mount. Extensive fixes and improvements
675to error logging (strip redundant newlines, change debug macros to ensure newline
676passed in and to be more consistent). Fix writepage wrong file handle problem,
677a readonly file handle could be incorrectly used to attempt to write out
678file updates through the page cache to multiply open files. This could cause
679the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
680shares to the same Windows server when using different usernames
681(doing this to Samba servers worked but Windows was rejecting it) - now it is
682possible to use different userids when connecting to the same server from a
683Linux client. Fix oops when treeDisconnect called during unmount on
684previously freed socket.
685
686Version 0.60

829------------
8301) Fixed lockrange to be correct (it was one byte too short)
831
8322) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
833show range as locked when there is a conflict with an existing lock.
834
8353) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
836in most cases. Eventually will offer optional ability to query server for the correct perms.

8383) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
839but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
840session)
841
8424) Fixed error logging of valid mount options
843
8445) Removed logging of password field.
845
8466) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
847and cleaned them up and made them more consistent with other cifs functions.
848
8497) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700850(with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
