Steve French39798772006-05-31 22:40:51 +00001Version 1.44
2------------
3Rewritten sessionsetup support, including support for legacy SMB
4session setup needed for OS/2 and older servers such as Windows 95 and 98.
Steve French5bafd762006-06-07 00:18:43 +00005Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
6so we can do search (ls etc.) to OS/2. Do not send NTCreateX
7or recent levels of FindFirst unless server says it supports NT SMBs
Steve French1717ffc2006-06-08 05:41:32 +00008(instead use legacy equivalents from LANMAN dialect). Fix to allow
9NTLMv2 authentication support (now can use stronger password hashing
Steve French750d1152006-06-27 06:28:30 +000010on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
11Allow override of global cifs security flags on mount via "sec=" option(s).

Steve Frenchfc94cdb2006-05-30 18:03:32 +000013Version 1.43
14------------
15POSIX locking to servers which support CIFS POSIX Extensions
Steve Frencha878fb22006-05-30 18:04:19 +000016(disabled by default controlled by proc/fs/cifs/Experimental).
17Handle conversion of long share names (especially Asian languages)
Steve French26a21b92006-05-31 18:05:34 +000018to Unicode during mount. Fix memory leak in sess struct on reconnect.
19Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
20cifs open which helps rare case when setpathinfo fails or server does
21not support it.
Steve Frenchfc94cdb2006-05-30 18:03:32 +000022
Steve French13298de2006-03-03 10:45:19 +000023Version 1.42
24------------
25Fix slow oplock break when mounted to different servers at the same time and
Steve French60808232006-04-22 15:53:05 +000026the tids match and we try to find matching fid on wrong server. Fix read
27looping when signing required by server (2.6.16 kernel only). Fix readdir
28vs. rename race which could cause each to hang. Return . and .. even
29if server does not. Allow searches to skip first three entries and
30begin at any location. Fix oops in find_writeable_file.
Steve French13298de2006-03-03 10:45:19 +000031
Steve French12b3b8f2006-02-09 21:12:47 +000032Version 1.41
33------------
34Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
35configure stronger authentication. Fix sfu symlinks so they can
Steve French184ed212006-02-24 06:15:11 +000036be followed (not just recognized). Fix wraparound of bcc on
37read responses when buffer size over 64K and also fix wrap of
38max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
39cifs_user_read and cifs_readpages (when EAGAIN on send of smb
Steve French08547b02006-02-28 22:39:25 +000040on socket is returned over and over). Add POSIX (advisory) byte range
41locking support (requires server with newest CIFS UNIX Extensions
Steve French083d3a22006-03-03 09:53:36 +000042to the protocol implemented). Slow down negprot slightly in port 139
43RFC1001 case to give session_init time on buggy servers.
Steve French12b3b8f2006-02-09 21:12:47 +000044
Steve French83451872005-12-01 17:12:59 -080045Version 1.40
46------------
Steve French84afc292005-12-02 13:32:45 -080047Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
Steve French0a4b92c2006-01-12 15:44:21 -080048of readpages by eliminating one extra memcpy. Allow update of file size
49from remote server even if file is open for write as long as mount is
Steve Frencheeac8042006-01-13 21:34:58 -080050directio. Recognize share mode security and send NTLM encrypted password
51on tree connect if share mode negotiated.
Steve French83451872005-12-01 17:12:59 -080052
Steve French23e7dd72005-10-20 13:44:56 -070053Version 1.39
54------------
Steve French3abb9272005-11-28 08:16:13 -080055Defer close of a file handle slightly if pending writes depend on that handle
Steve French23e7dd72005-10-20 13:44:56 -070056(this reduces the EBADF bad file handle errors that can be logged under heavy
Steve French3c50c612005-11-10 17:31:33 -080057stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
Steve French3abb9272005-11-28 08:16:13 -080058Fix SFU style symlinks and mknod needed for servers which do not support the
59CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
60dentries so files that the client sees as deleted but that later get created
Steve French6473a552005-11-29 20:20:10 -080061on the server will be recognized. Add client side permission check on setattr.
Steve French83451872005-12-01 17:12:59 -080062Timeout stuck requests better (where server has never responded or sent corrupt
63responses)
Steve French23e7dd72005-10-20 13:44:56 -070064
Steve French190fdeb2005-10-10 11:48:26 -070065Version 1.38
66------------
67Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
68to be smaller at first (but increasing) so large write performance performance
69over GigE is better. Do not hang thread on illegal byte range lock response
70from Windows (Windows can send an RFC1001 size which does not match smb size) by
71allowing an SMBs TCP length to be up to a few bytes longer than it should be.
72wsize and rsize can now be larger than negotiated buffer size if server
73supports large readx/writex, even when directio mount flag not specified.
74Write size will in many cases now be 16K instead of 4K which greatly helps
Steve French4ca9c192005-10-10 19:52:13 -070075file copy performance on lightly loaded networks. Fix oops in dnotify
Steve French1047abc2005-10-11 19:58:06 -070076when experimental config flag enabled. Make cifsFYI more granular.
Steve French190fdeb2005-10-10 11:48:26 -070077
Steve Frencheafe8702005-09-15 21:47:30 -070078Version 1.37
79------------
80Fix readdir caching when unlink removes file in current search buffer,
81and this is followed by a rewind search to just before the deleted entry.
Steve Frenche30dcf32005-09-20 20:49:16 -070082Do not attempt to set ctime unless atime and/or mtime change requested
Steve French20962432005-09-21 22:05:57 -070083(most servers throw it away anyway). Fix length check of received smbs
Steve French70ca7342005-09-22 16:32:06 -070084to be more accurate. Fix big endian problem with mapchars mount option,
85and with a field returned by statfs.
Steve Frencheafe8702005-09-15 21:47:30 -070086
Steve Frenchc46fa8a2005-08-18 20:49:57 -070087Version 1.36
88------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -070089Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
Steve French6b8edfe2005-08-23 20:26:03 -070090For these older servers, add option for passing netbios name of server in
Steve French16abbec2005-08-30 13:10:14 -070091on mount (servernetbiosname). Add suspend support for power management, to
92avoid cifsd thread preventing software suspend from working.
Steve Frenchc46fa8a2005-08-18 20:49:57 -070093Add mount option for disabling the default behavior of sending byte range lock
94requests to the server (necessary for certain applications which break with
95mandatory lock behavior such as Evolution), and also mount option for
96requesting case insensitive matching for path based requests (requesting
97case sensitive is the default).
98
Steve Frenchf4cfd692005-07-14 18:29:02 -050099Version 1.35
100------------
101Add writepage performance improvements. Fix path name conversions
102for long filenames on mounts which were done with "mapchars" mount option
Steve Frencha10faeb22005-08-22 21:38:31 -0700103specified. Ensure multiplex ids do not collide. Fix case in which
104rmmod can oops if done soon after last unmount. Fix truncated
105search (readdir) output when resume filename was a long filename.
106Fix filename conversion when mapchars mount option was specified and
107filename was a long filename.
Steve Frenchf4cfd692005-07-14 18:29:02 -0500108
Steve French11aa0142005-04-28 22:41:10 -0700109Version 1.34
110------------
111Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
Steve French31ca3bc2005-04-28 22:41:11 -0700112Do not oops if root user kills cifs oplock kernel thread or
113kills the cifsd thread (NB: killing the cifs kernel threads is not
114recommended, unmount and rmmod cifs will kill them when they are
Steve French68575472005-04-30 11:10:57 -0700115no longer needed). Fix readdir to ASCII servers (ie older servers
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700116which do not support Unicode) and also require asterisk.
Steve French3079ca62005-06-09 14:44:07 -0700117Fix out of memory case in which data could be written one page
118off in the page cache.
Steve French11aa0142005-04-28 22:41:10 -0700119
Steve French966ca922005-04-28 22:41:08 -0700120Version 1.33
121------------
122Fix caching problem, in which readdir of directory containing a file
123which was cached could cause the file's time stamp to be updated
124without invalidating the readahead data (so we could get stale
125file data on the client for that file even as the server copy changed).
Steve Frenchcd634992005-04-28 22:41:10 -0700126Cleanup response processing so cifsd can not loop when abnormally
127terminated.
Steve French966ca922005-04-28 22:41:08 -0700128
129
Steve Frenchf654bac2005-04-28 22:41:04 -0700130Version 1.32
Linus Torvalds1da177e2005-04-16 15:20:36 -0700131------------
132Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
133transact response for an SMB request and search entry split across two frames.
Steve Frenchf654bac2005-04-28 22:41:04 -0700134Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
135as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
136unless server explicitly claims to support them in CIFS Unix extensions
Steve Frenchad009ac2005-04-28 22:41:05 -0700137POSIX ACL capability bit. Fix packet signing when multiuser mounting with
Steve Frenchcbe04762005-04-28 22:41:05 -0700138different users from the same client to the same server. Fix oops in
Steve French6a0b4822005-04-28 22:41:05 -0700139cifs_close. Add mount option for remapping reserved characters in
140filenames (also allow recognizing files with created by SFU which have any
Steve French737b7582005-04-28 22:41:06 -0700141of these seven reserved characters, except backslash, to be recognized).
Steve French848f3fc2005-04-28 22:41:07 -0700142Fix invalid transact2 message (we were sometimes trying to interpret
Steve French099a58f2005-04-28 22:41:07 -0700143oplock breaks as SMB responses). Add ioctl for checking that the
144current uid matches the uid of the mounter (needed by umount.cifs).
145Reduce the number of large buffer allocations in cifs response processing
146(significantly reduces memory pressure under heavy stress with multiple
147processes accessing the same server at the same time).
Steve Frenchf654bac2005-04-28 22:41:04 -0700148
149Version 1.31
150------------
Linus Torvalds1da177e2005-04-16 15:20:36 -0700151Fix updates of DOS attributes and time fields so that files on NT4 servers
152do not get marked delete on close. Display sizes of cifs buffer pools in
153cifs stats. Fix oops in unmount when cifsd thread being killed by
154shutdown. Add generic readv/writev and aio support. Report inode numbers
155consistently in readdir and lookup (when serverino mount option is
156specified use the inode number that the server reports - for both lookup
157and readdir, otherwise by default the locally generated inode number is used
158for inodes created in either path since servers are not always able to
159provide unique inode numbers when exporting multiple volumes from under one
160sharename).
161
162Version 1.30
163------------
164Allow new nouser_xattr mount parm to disable xattr support for user namespace.
165Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
166(mostly affects NT4 servers) by retry with handle based network operation.
167Add new POSIX Query FS Info for returning statfs info more accurately.
168Handle passwords with multiple commas in them.
169
170Version 1.29
171------------
172Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
173Fix capabilities flags for large readx so as to allow reads larger than 64K.
174
175Version 1.28
176------------
177Add module init parm for large SMB buffer size (to allow it to be changed
178from its default of 16K) which is especially useful for large file copy
179when mounting with the directio mount option. Fix oops after
180returning from mount when experimental ExtendedSecurity enabled and
181SpnegoNegotiated returning invalid error. Fix case to retry better when
182peek returns from 1 to 3 bytes on socket which should have more data.
183Fixed path based calls (such as cifs lookup) to handle path names
184longer than 530 (now can handle PATH_MAX). Fix pass through authentication
185from Samba server to DC (Samba required dummy LM password).
186
187Version 1.27
188------------
189Turn off DNOTIFY (directory change notification support) by default
190(unless built with the experimental flag) to fix hang with KDE
191file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
192waiting on an SMB response) in SendReceive when session dies but
193reconnects quickly from another task. Add module init parms for
194minimum number of large and small network buffers in the buffer pools,
195and for the maximum number of simultaneous requests.
196
197Version 1.26
198------------
199Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
200and other POSIX CIFS compliant servers. Fix error mapping for getfacl
201to EOPNOTSUPP when server does not support posix acls on the wire. Fix
202improperly zeroed buffer in CIFS Unix extensions set times call.
203
204Version 1.25
205------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700206Fix internationalization problem in cifs readdir with filenames that map to
Alexey Dobriyan4de151d2006-03-22 00:13:35 +0100207longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
Linus Torvalds1da177e2005-04-16 15:20:36 -0700208for readdir to netapp servers. Fix search rewind (seek into readdir to return
209non-consecutive entries). Do not do readdir when server negotiates
210buffer size to small to fit filename. Add support for reading POSIX ACLs from
211the server (add also acl and noacl mount options).
212
213Version 1.24
214------------
215Optionally allow using server side inode numbers, rather than client generated
216ones by specifying mount option "serverino" - this is required for some apps
217to work which double check hardlinked files and have persistent inode numbers.
218
219Version 1.23
220------------
221Multiple bigendian fixes. On little endian systems (for reconnect after
222network failure) fix tcp session reconnect code so we do not try first
223to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
224as directories rather than symlinks because we can do follow link on them.
225
226Version 1.22
227------------
228Add config option to enable XATTR (extended attribute) support, mapping
229xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
230minor fixes pointed out by the Stanford SWAT checker (mostly missing
231or out of order NULL pointer checks in little used error paths).
232
233Version 1.21
234------------
235Add new mount parm to control whether mode check (generic_permission) is done
236on the client. If Unix extensions are enabled and the uids on the client
237and server do not match, client permission checks are meaningless on
238server uids that do not exist on the client (this does not affect the
239normal ACL check which occurs on the server). Fix default uid
240on mknod to match create and mkdir. Add optional mount parm to allow
241override of the default uid behavior (in which the server sets the uid
242and gid of newly created files). Normally for network filesystem mounts
243user want the server to set the uid/gid on newly created files (rather than
244using uid of the client processes you would in a local filesystem).
245
246Version 1.20
247------------
248Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
249info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
250(in build_wildcard_path_from_dentry). Fix mknod to pass type field
251(block/char/fifo) properly. Remove spurious mount warning log entry when
252credentials passed as mount argument. Set major/minor device number in
253inode for block and char devices when unix extensions enabled.
254
255Version 1.19
256------------
257Fix /proc/fs/cifs/Stats and DebugData display to handle larger
258amounts of return data. Properly limit requests to MAX_REQ (50
259is the usual maximum active multiplex SMB/CIFS requests per server).
260Do not kill cifsd (and thus hurt the other SMB session) when more than one
261session to the same server (but with different userids) exists and one
262of the two user's smb sessions is being removed while leaving the other.
263Do not loop reconnecting in cifsd demultiplex thread when admin
264kills the thread without going through unmount.
265
266Version 1.18
267------------
268Do not rename hardlinked files (since that should be a noop). Flush
269cached write behind data when reopening a file after session abend,
270except when already in write. Grab per socket sem during reconnect
271to avoid oops in sendmsg if overlapping with reconnect. Do not
272reset cached inode file size on readdir for files open for write on
273client.
274
275
276Version 1.17
277------------
278Update number of blocks in file so du command is happier (in Linux a fake
279blocksize of 512 is required for calculating number of blocks in inode).
280Fix prepare write of partial pages to read in data from server if possible.
281Fix race on tcpStatus field between unmount and reconnection code, causing
282cifsd process sometimes to hang around forever. Improve out of memory
283checks in cifs_filldir
284
285Version 1.16
286------------
287Fix incorrect file size in file handle based setattr on big endian hardware.
288Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
289and closing file structs in writepage/partialpagewrite. Add statistics
290for each mounted share (new menuconfig option). Fix endianness problem in
291volume information displayed in /proc/fs/cifs/DebugData (only affects
292affects big endian architectures). Prevent renames while constructing
293path names for open, mkdir and rmdir.
294
295Version 1.15
296------------
297Change to mempools for alloc smb request buffers and multiplex structs
298to better handle low memory problems (and potential deadlocks).
299
300Version 1.14
301------------
302Fix incomplete listings of large directories on Samba servers when Unix
303extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
304rename deadlock when writing out dirty pages at same time.
305
306Version 1.13
307------------
308Fix open of files in which O_CREATE can cause the mode to change in
309some cases. Fix case in which retry of write overlaps file close.
310Fix PPC64 build error. Reduce excessive stack usage in smb password
311hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
312
313Version 1.12
314------------
315Fixes for large file copy, signal handling, socket retry, buffer
316allocation and low memory situations.
317
318Version 1.11
319------------
320Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
321also now allowing support for specifying client netbiosname. NT4 support added.
322
323Version 1.10
324------------
325Fix reconnection (and certain failed mounts) to properly wake up the
326blocked users thread so it does not seem hung (in some cases was blocked
327until the cifs receive timeout expired). Fix spurious error logging
328to kernel log when application with open network files killed.
329
330Version 1.09
331------------
332Fix /proc/fs module unload warning message (that could be logged
333to the kernel log). Fix intermittent failure in connectathon
334test7 (hardlink count not immediately refreshed in case in which
335inode metadata can be incorrectly kept cached when time near zero)
336
337Version 1.08
338------------
339Allow file_mode and dir_mode (specified at mount time) to be enforced
340locally (the server already enforced its own ACLs too) for servers
341that do not report the correct mode (do not support the
342CIFS Unix Extensions).
343
344Version 1.07
345------------
346Fix some small memory leaks in some unmount error paths. Fix major leak
347of cache pages in readpages causing multiple read oriented stress
348testcases (including fsx, and even large file copy) to fail over time.
349
350Version 1.06
351------------
352Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
353This allows files that differ only in case and improves performance of file
354creation and file open to such servers. Fix semaphore conflict which causes
355slow delete of open file to Samba (which unfortunately can cause an oplock
356break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
357
358Version 1.05
359------------
360fixes to cifs_readpages for fsx test case
361
362Version 1.04
363------------
364Fix caching data integrity bug when extending file size especially when no
365oplock on file. Fix spurious logging of valid already parsed mount options
366that are parsed outside of the cifs vfs such as nosuid.
367
368
369Version 1.03
370------------
371Connect to server when port number override not specified, and tcp port
372unitialized. Reset search to restart at correct file when kernel routine
373filldir returns error during large directory searches (readdir).

575
576Version 0.69
577------------
578Fix buffer overrun in readdir which caused intermittent kernel oopses.
579Fix writepage code to release kmap on write data. Allow "-ip=" new
580mount option to be passed in on parameter distinct from the first part
581(server name portion of) the UNC name. Allow override of the
582tcp port of the target server via new mount option "-port="
583
584Version 0.68
585------------

589
590
591Version 0.67
592------------
593Fix signal sending so that captive thread (cifsd) exits on umount
594(which was causing the warning in kmem_cache_free of the request buffers
595at rmmod time). This had broken as a sideeffect of the recent global
596kernel change to daemonize. Fix memory leak in readdir code which
597showed up in "ls -R" (and applications that did search rewinding).
598
599Version 0.66

625------------
626Fix temporary socket leak when bad userid or password specified
627(or other SMBSessSetup failure). Increase maximum buffer size to slightly

632------------
633Fix oops when username not passed in on mount. Extensive fixes and improvements
634to error logging (strip redundant newlines, change debug macros to ensure newline
635passed in and to be more consistent). Fix writepage wrong file handle problem,
636a readonly file handle could be incorrectly used to attempt to write out
637file updates through the page cache to multiply open files. This could cause
638the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
639shares to the same Windows server when using different usernames
640(doing this to Samba servers worked but Windows was rejecting it) - now it is
641possible to use different userids when connecting to the same server from a
642Linux client. Fix oops when treeDisconnect called during unmount on
643previously freed socket.

659
660Version 0.57
661------------

7912) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
792show range as locked when there is a conflict with an existing lock.
793
7943) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories

8014) Fixed error logging of valid mount options
802
8035) Removed logging of password field.
804
8056) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
806and cleaned them up and made them more consistent with other cifs functions.
807
8087) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700809(with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
