Steve Frenchb609f062007-07-09 07:55:14 +00006Version 1.50
7------------
Steve French7521a3c2007-07-11 18:30:34 +00008Fix NTLMv2 signing. NFS server mounted over cifs works (if cifs mount is
Steve French2d785a52007-07-15 01:48:57 +00009done with "serverino" mount option). Add support for POSIX Unlink
10(helps with certain sharing violation cases when server such as
Steve Frencha403a0a2007-07-26 15:54:16 +000011Samba supports newer POSIX CIFS Protocol Extensions). Add "nounix"
12mount option to allow disabling the CIFS Unix Extensions for just
13that mount. Fix hang on spinlock in find_writable_file (race when
Jeff Layton39db8102007-08-24 03:16:51 +000014reopening file after session crash). Byte range unlock request to
15windows server could unlock more bytes (on server copy of file)
16than intended if start of unlock request is well before start of
17a previous byte range lock that we issued.

Steve French5858ae42007-04-25 11:59:10 +000019Version 1.49
20------------
21IPv6 support. Enable ipv6 addresses to be passed on mount (put the ipv6
22address after the "ip=" mount option, at least until mount.cifs is fixed to
Steve French4523cc32007-04-30 20:13:06 +000023handle DNS host to ipv6 name translation). Accept override of uid or gid
24on mount even when Unix Extensions are negotiated (it used to be ignored
25when Unix Extensions were ignored). This allows users to override the
26default uid and gid for files when they are certain that the uids or
Jeff Layton8426c392007-05-05 03:27:49 +000027gids on the server do not match those of the client. Make "sec=none"
28mount override username (so that null user connection is attempted)
Steve French75865f8c2007-06-24 18:30:48 +000029to match what documentation said. Support for very large reads, over 127K,
30available to some newer servers (such as Samba 3.0.26 and later but
31note that it also requires setting CIFSMaxBufSize at module install
32time to a larger value which may hurt performance in some cases).
Jeff38c10a12007-07-06 21:10:07 +000033Make sign option force signing (or fail if server does not support it).
Steve French5858ae42007-04-25 11:59:10 +000034
35Version 1.48
Steve French3677db12007-02-26 16:46:11 +000036------------
37Fix mtime bouncing around from local idea of last write times to remote time.
38Fix hang (in i_size_read) when simultaneous size update of same remote file
Steve French8a236262007-03-06 00:31:00 +000039on smp system corrupts sequence number. Do not reread unnecessarily partial page
40(which we are about to overwrite anyway) when writing out file opened rw.
Alan Tysonf5c1e2e2007-03-10 06:05:14 +000041When DOS attribute of file on non-Unix server's file changes on the server side
42from read-only back to read-write, reflect this change in default file mode
Steve French066fcb02007-03-23 00:45:08 +000043(we had been leaving a file's mode read-only until the inode were reloaded).
44Allow setting of attribute back to ATTR_NORMAL (removing readonly dos attribute
45when archive dos attribute not set and we are changing mode back to writeable
Steve French5268df22007-04-06 19:28:16 +000046on server which does not support the Unix Extensions). Remove read only dos
47attribute on chmod when adding any write permission (ie on any of
48user/group/other (not all of user/group/other ie 0222) when
Steve French2dd29d32007-04-23 22:07:35 +000049mounted to windows. Add support for POSIX MkDir (slight performance
50enhancement and eliminates the network race between the mkdir and set
51path info of the mode).

Steve French405c5142006-12-23 18:44:33 +000054Version 1.47
55------------
56Fix oops in list_del during mount caused by unaligned string.
Steve French595dcfe2007-02-08 18:11:42 +000057Fix file corruption which could occur on some large file
58copies caused by writepages page i/o completion bug.
Steve Frencha8507902007-02-06 20:43:30 +000059Seek to SEEK_END forces check for update of file size for non-cached
Steve French8af18972007-02-14 04:42:51 +000060files. Allow file size to be updated on remote extend of locally open,
61non-cached file. Fix reconnect to newer Samba servers (or other servers
62which support the CIFS Unix/POSIX extensions) so that we again tell the
63server the Unix/POSIX cifs capabilities which we support (SetFSInfo).
64Add experimental support for new POSIX Open/Mkdir (which returns
65stat information on the open, and allows setting the mode).
Steve French405c5142006-12-23 18:44:33 +000066
Steve French2fe87f02006-09-21 07:02:52 +000067Version 1.46
68------------
69Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
Steve French4b952a92006-10-30 21:46:13 +000070Allow null user to be specified on mount ("username="). Do not return
71EINVAL on readdir when filldir fails due to overwritten blocksize
Steve French8e87d4d2006-11-02 03:45:24 +000072(fixes FC problem). Return error in rename 2nd attempt retry (ie report
73if rename by handle also fails, after rename by path fails, we were
Steve French33ec32f2006-12-08 04:14:28 +000074not reporting whether the retry worked or not). Fix NTLMv2 to
75work to Windows servers (mount with option "sec=ntlmv2").
Steve French2fe87f02006-09-21 07:02:52 +000076
Steve French3a5ff612006-07-14 22:37:11 +000077Version 1.45
78------------
79Do not time out lockw calls when using posix extensions. Do not
80time out requests if server still responding reasonably fast
Steve Frenche466e482006-08-15 13:07:18 +000081on requests on other threads. Improve POSIX locking emulation,
82(lock cancel now works, and unlock of merged range works even
83to Windows servers now). Fix oops on mount to lanman servers
Steve Frenchea4c07d2006-08-16 19:44:25 +000084(win9x, os/2 etc.) when null password. Do not send listxattr
Steve French2fe87f02006-09-21 07:02:52 +000085(SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
86problem (instantiate inodes/dentries in right order for readdir).
Steve French3a5ff612006-07-14 22:37:11 +000087
Steve French39798772006-05-31 22:40:51 +000088Version 1.44
89------------
90Rewritten sessionsetup support, including support for legacy SMB
91session setup needed for OS/2 and older servers such as Windows 95 and 98.
Steve French5bafd762006-06-07 00:18:43 +000092Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
93so we can do search (ls etc.) to OS/2. Do not send NTCreateX
94or recent levels of FindFirst unless server says it supports NT SMBs
Steve French1717ffc2006-06-08 05:41:32 +000095(instead use legacy equivalents from LANMAN dialect). Fix to allow
96NTLMv2 authentication support (now can use stronger password hashing
Steve French750d1152006-06-27 06:28:30 +000097on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
98Allow override of global cifs security flags on mount via "sec=" option(s).
Steve French39798772006-05-31 22:40:51 +000099
Steve Frenchfc94cdb2006-05-30 18:03:32 +0000100Version 1.43
101------------
102POSIX locking to servers which support CIFS POSIX Extensions
Steve Frencha878fb22006-05-30 18:04:19 +0000103(disabled by default controlled by proc/fs/cifs/Experimental).
104Handle conversion of long share names (especially Asian languages)
Steve French26a21b92006-05-31 18:05:34 +0000105to Unicode during mount. Fix memory leak in sess struct on reconnect.
106Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
107cifs open which helps rare case when setpathinfo fails or server does
108not support it.
Steve Frenchfc94cdb2006-05-30 18:03:32 +0000109
Steve French13298de2006-03-03 10:45:19 +0000110Version 1.42
111------------
112Fix slow oplock break when mounted to different servers at the same time and
Steve French60808232006-04-22 15:53:05 +0000113the tids match and we try to find matching fid on wrong server. Fix read
114looping when signing required by server (2.6.16 kernel only). Fix readdir
115vs. rename race which could cause each to hang. Return . and .. even
116if server does not. Allow searches to skip first three entries and
117begin at any location. Fix oops in find_writeable_file.
Steve French13298de2006-03-03 10:45:19 +0000118
Steve French12b3b8f2006-02-09 21:12:47 +0000119Version 1.41
120------------
121Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
122configure stronger authentication. Fix sfu symlinks so they can
Steve French184ed212006-02-24 06:15:11 +0000123be followed (not just recognized). Fix wraparound of bcc on
124read responses when buffer size over 64K and also fix wrap of
125max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
126cifs_user_read and cifs_readpages (when EAGAIN on send of smb
Steve French08547b02006-02-28 22:39:25 +0000127on socket is returned over and over). Add POSIX (advisory) byte range
128locking support (requires server with newest CIFS UNIX Extensions
Steve French083d3a22006-03-03 09:53:36 +0000129to the protocol implemented). Slow down negprot slightly in port 139
130RFC1001 case to give session_init time on buggy servers.
Steve French12b3b8f2006-02-09 21:12:47 +0000131
Steve French83451872005-12-01 17:12:59 -0800132Version 1.40
133------------
Steve French84afc292005-12-02 13:32:45 -0800134Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
Steve French0a4b92c2006-01-12 15:44:21 -0800135of readpages by eliminating one extra memcpy. Allow update of file size
136from remote server even if file is open for write as long as mount is
Steve Frencheeac8042006-01-13 21:34:58 -0800137directio. Recognize share mode security and send NTLM encrypted password
138on tree connect if share mode negotiated.
Steve French83451872005-12-01 17:12:59 -0800139
Steve French23e7dd72005-10-20 13:44:56 -0700140Version 1.39
141------------
Steve French3abb9272005-11-28 08:16:13 -0800142Defer close of a file handle slightly if pending writes depend on that handle
Steve French23e7dd72005-10-20 13:44:56 -0700143(this reduces the EBADF bad file handle errors that can be logged under heavy
Steve French3c50c612005-11-10 17:31:33 -0800144stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
Steve French3abb9272005-11-28 08:16:13 -0800145Fix SFU style symlinks and mknod needed for servers which do not support the
146CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
147dentries so files that the client sees as deleted but that later get created
Steve French6473a552005-11-29 20:20:10 -0800148on the server will be recognized. Add client side permission check on setattr.
Steve French83451872005-12-01 17:12:59 -0800149Timeout stuck requests better (where server has never responded or sent corrupt
150responses)
Steve French23e7dd72005-10-20 13:44:56 -0700151
Steve French190fdeb2005-10-10 11:48:26 -0700152Version 1.38
153------------
154Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
155to be smaller at first (but increasing) so large write performance performance
156over GigE is better. Do not hang thread on illegal byte range lock response
157from Windows (Windows can send an RFC1001 size which does not match smb size) by
158allowing an SMBs TCP length to be up to a few bytes longer than it should be.
159wsize and rsize can now be larger than negotiated buffer size if server
160supports large readx/writex, even when directio mount flag not specified.
161Write size will in many cases now be 16K instead of 4K which greatly helps
Steve French4ca9c192005-10-10 19:52:13 -0700162file copy performance on lightly loaded networks. Fix oops in dnotify
Steve French1047abc2005-10-11 19:58:06 -0700163when experimental config flag enabled. Make cifsFYI more granular.
Steve French190fdeb2005-10-10 11:48:26 -0700164
Steve Frencheafe8702005-09-15 21:47:30 -0700165Version 1.37
166------------
167Fix readdir caching when unlink removes file in current search buffer,
168and this is followed by a rewind search to just before the deleted entry.
Steve Frenche30dcf32005-09-20 20:49:16 -0700169Do not attempt to set ctime unless atime and/or mtime change requested
Steve French20962432005-09-21 22:05:57 -0700170(most servers throw it away anyway). Fix length check of received smbs
Steve French70ca7342005-09-22 16:32:06 -0700171to be more accurate. Fix big endian problem with mapchars mount option,
172and with a field returned by statfs.
Steve Frencheafe8702005-09-15 21:47:30 -0700173
Steve Frenchc46fa8a2005-08-18 20:49:57 -0700174Version 1.36
175------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700176Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
Steve French6b8edfe2005-08-23 20:26:03 -0700177For these older servers, add option for passing netbios name of server in
Steve French16abbec2005-08-30 13:10:14 -0700178on mount (servernetbiosname). Add suspend support for power management, to
179avoid cifsd thread preventing software suspend from working.
Steve Frenchc46fa8a2005-08-18 20:49:57 -0700180Add mount option for disabling the default behavior of sending byte range lock
181requests to the server (necessary for certain applications which break with
182mandatory lock behavior such as Evolution), and also mount option for
183requesting case insensitive matching for path based requests (requesting
184case sensitive is the default).
185
Steve Frenchf4cfd692005-07-14 18:29:02 -0500186Version 1.35
187------------
188Add writepage performance improvements. Fix path name conversions
189for long filenames on mounts which were done with "mapchars" mount option
Steve Frencha10faeb22005-08-22 21:38:31 -0700190specified. Ensure multiplex ids do not collide. Fix case in which
191rmmod can oops if done soon after last unmount. Fix truncated
192search (readdir) output when resume filename was a long filename.
193Fix filename conversion when mapchars mount option was specified and
194filename was a long filename.
Steve Frenchf4cfd692005-07-14 18:29:02 -0500195
Steve French11aa0142005-04-28 22:41:10 -0700196Version 1.34
197------------
198Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
Steve French31ca3bc2005-04-28 22:41:11 -0700199Do not oops if root user kills cifs oplock kernel thread or
200kills the cifsd thread (NB: killing the cifs kernel threads is not
201recommended, unmount and rmmod cifs will kill them when they are
Steve French68575472005-04-30 11:10:57 -0700202no longer needed). Fix readdir to ASCII servers (ie older servers
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700203which do not support Unicode) and also require asterisk.
Steve French3079ca62005-06-09 14:44:07 -0700204Fix out of memory case in which data could be written one page
205off in the page cache.
Steve French11aa0142005-04-28 22:41:10 -0700206
Steve French966ca922005-04-28 22:41:08 -0700207Version 1.33
208------------
209Fix caching problem, in which readdir of directory containing a file
210which was cached could cause the file's time stamp to be updated
211without invalidating the readahead data (so we could get stale
212file data on the client for that file even as the server copy changed).
Steve Frenchcd634992005-04-28 22:41:10 -0700213Cleanup response processing so cifsd can not loop when abnormally
214terminated.
Steve French966ca922005-04-28 22:41:08 -0700215

Linus Torvalds1da177e2005-04-16 15:20:36 -0700218------------
219Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
220transact response for an SMB request and search entry split across two frames.
Steve Frenchf654bac2005-04-28 22:41:04 -0700221Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
222as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
223unless server explicitly claims to support them in CIFS Unix extensions
Steve Frenchad009ac2005-04-28 22:41:05 -0700224POSIX ACL capability bit. Fix packet signing when multiuser mounting with
Steve Frenchcbe04762005-04-28 22:41:05 -0700225different users from the same client to the same server. Fix oops in
Steve French6a0b4822005-04-28 22:41:05 -0700226cifs_close. Add mount option for remapping reserved characters in
227filenames (also allow recognizing files with created by SFU which have any
Steve French737b7582005-04-28 22:41:06 -0700228of these seven reserved characters, except backslash, to be recognized).
Steve French848f3fc2005-04-28 22:41:07 -0700229Fix invalid transact2 message (we were sometimes trying to interpret
Steve French099a58f2005-04-28 22:41:07 -0700230oplock breaks as SMB responses). Add ioctl for checking that the
231current uid matches the uid of the mounter (needed by umount.cifs).
232Reduce the number of large buffer allocations in cifs response processing
233(significantly reduces memory pressure under heavy stress with multiple
234processes accessing the same server at the same time).
Steve Frenchf654bac2005-04-28 22:41:04 -0700235
236Version 1.31
237------------
Linus Torvalds1da177e2005-04-16 15:20:36 -0700238Fix updates of DOS attributes and time fields so that files on NT4 servers
239do not get marked delete on close. Display sizes of cifs buffer pools in
240cifs stats. Fix oops in unmount when cifsd thread being killed by
241shutdown. Add generic readv/writev and aio support. Report inode numbers
242consistently in readdir and lookup (when serverino mount option is
243specified use the inode number that the server reports - for both lookup
244and readdir, otherwise by default the locally generated inode number is used
245for inodes created in either path since servers are not always able to
246provide unique inode numbers when exporting multiple volumes from under one
247sharename).
248
249Version 1.30
250------------
251Allow new nouser_xattr mount parm to disable xattr support for user namespace.
252Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
253(mostly affects NT4 servers) by retry with handle based network operation.
254Add new POSIX Query FS Info for returning statfs info more accurately.
255Handle passwords with multiple commas in them.
256
257Version 1.29
258------------
259Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
260Fix capabilities flags for large readx so as to allow reads larger than 64K.
261
262Version 1.28
263------------
264Add module init parm for large SMB buffer size (to allow it to be changed
265from its default of 16K) which is especially useful for large file copy
266when mounting with the directio mount option. Fix oops after
267returning from mount when experimental ExtendedSecurity enabled and
268SpnegoNegotiated returning invalid error. Fix case to retry better when
269peek returns from 1 to 3 bytes on socket which should have more data.
270Fixed path based calls (such as cifs lookup) to handle path names
271longer than 530 (now can handle PATH_MAX). Fix pass through authentication
272from Samba server to DC (Samba required dummy LM password).
273
274Version 1.27
275------------
276Turn off DNOTIFY (directory change notification support) by default
277(unless built with the experimental flag) to fix hang with KDE
278file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
279waiting on an SMB response) in SendReceive when session dies but
280reconnects quickly from another task. Add module init parms for
281minimum number of large and small network buffers in the buffer pools,
282and for the maximum number of simultaneous requests.
283
284Version 1.26
285------------
286Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
287and other POSIX CIFS compliant servers. Fix error mapping for getfacl
288to EOPNOTSUPP when server does not support posix acls on the wire. Fix
289improperly zeroed buffer in CIFS Unix extensions set times call.
290
291Version 1.25
292------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700293Fix internationalization problem in cifs readdir with filenames that map to
Alexey Dobriyan4de151d2006-03-22 00:13:35 +0100294longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
Linus Torvalds1da177e2005-04-16 15:20:36 -0700295for readdir to netapp servers. Fix search rewind (seek into readdir to return
296non-consecutive entries). Do not do readdir when server negotiates
297buffer size to small to fit filename. Add support for reading POSIX ACLs from
298the server (add also acl and noacl mount options).
299
300Version 1.24
301------------
302Optionally allow using server side inode numbers, rather than client generated
303ones by specifying mount option "serverino" - this is required for some apps
304to work which double check hardlinked files and have persistent inode numbers.
305
306Version 1.23
307------------
308Multiple bigendian fixes. On little endian systems (for reconnect after
309network failure) fix tcp session reconnect code so we do not try first
310to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
311as directories rather than symlinks because we can do follow link on them.
312
313Version 1.22
314------------
315Add config option to enable XATTR (extended attribute) support, mapping
316xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
317minor fixes pointed out by the Stanford SWAT checker (mostly missing
318or out of order NULL pointer checks in little used error paths).
319
320Version 1.21
321------------
322Add new mount parm to control whether mode check (generic_permission) is done
323on the client. If Unix extensions are enabled and the uids on the client
324and server do not match, client permission checks are meaningless on
325server uids that do not exist on the client (this does not affect the
326normal ACL check which occurs on the server). Fix default uid
327on mknod to match create and mkdir. Add optional mount parm to allow
328override of the default uid behavior (in which the server sets the uid
329and gid of newly created files). Normally for network filesystem mounts
330user want the server to set the uid/gid on newly created files (rather than
331using uid of the client processes you would in a local filesystem).
332
333Version 1.20
334------------
335Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
336info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
337(in build_wildcard_path_from_dentry). Fix mknod to pass type field
338(block/char/fifo) properly. Remove spurious mount warning log entry when
339credentials passed as mount argument. Set major/minor device number in
340inode for block and char devices when unix extensions enabled.
341
342Version 1.19
343------------
344Fix /proc/fs/cifs/Stats and DebugData display to handle larger
345amounts of return data. Properly limit requests to MAX_REQ (50
346is the usual maximum active multiplex SMB/CIFS requests per server).
347Do not kill cifsd (and thus hurt the other SMB session) when more than one
348session to the same server (but with different userids) exists and one
349of the two user's smb sessions is being removed while leaving the other.
350Do not loop reconnecting in cifsd demultiplex thread when admin
351kills the thread without going through unmount.
352
353Version 1.18
354------------
355Do not rename hardlinked files (since that should be a noop). Flush
356cached write behind data when reopening a file after session abend,
357except when already in write. Grab per socket sem during reconnect
358to avoid oops in sendmsg if overlapping with reconnect. Do not
359reset cached inode file size on readdir for files open for write on
360client.
361
362
363Version 1.17
364------------
365Update number of blocks in file so du command is happier (in Linux a fake
366blocksize of 512 is required for calculating number of blocks in inode).
367Fix prepare write of partial pages to read in data from server if possible.
368Fix race on tcpStatus field between unmount and reconnection code, causing
369cifsd process sometimes to hang around forever. Improve out of memory
370checks in cifs_filldir
371
372Version 1.16
373------------
374Fix incorrect file size in file handle based setattr on big endian hardware.
375Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
376and closing file structs in writepage/partialpagewrite. Add statistics
377for each mounted share (new menuconfig option). Fix endianness problem in
378volume information displayed in /proc/fs/cifs/DebugData (only affects
379affects big endian architectures). Prevent renames while constructing
380path names for open, mkdir and rmdir.
381
382Version 1.15
383------------
384Change to mempools for alloc smb request buffers and multiplex structs
385to better handle low memory problems (and potential deadlocks).
386
387Version 1.14
388------------
389Fix incomplete listings of large directories on Samba servers when Unix
390extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
391rename deadlock when writing out dirty pages at same time.
392
393Version 1.13
394------------
395Fix open of files in which O_CREATE can cause the mode to change in
396some cases. Fix case in which retry of write overlaps file close.
397Fix PPC64 build error. Reduce excessive stack usage in smb password
398hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
399
400Version 1.12
401------------
402Fixes for large file copy, signal handling, socket retry, buffer
403allocation and low memory situations.
404
405Version 1.11
406------------
407Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
408also now allowing support for specifying client netbiosname. NT4 support added.
409
410Version 1.10
411------------
412Fix reconnection (and certain failed mounts) to properly wake up the
413blocked users thread so it does not seem hung (in some cases was blocked
414until the cifs receive timeout expired). Fix spurious error logging
415to kernel log when application with open network files killed.
416
417Version 1.09
418------------
419Fix /proc/fs module unload warning message (that could be logged
420to the kernel log). Fix intermittent failure in connectathon
421test7 (hardlink count not immediately refreshed in case in which
422inode metadata can be incorrectly kept cached when time near zero)
423
424Version 1.08
425------------
426Allow file_mode and dir_mode (specified at mount time) to be enforced
427locally (the server already enforced its own ACLs too) for servers
428that do not report the correct mode (do not support the
429CIFS Unix Extensions).
430
431Version 1.07
432------------
433Fix some small memory leaks in some unmount error paths. Fix major leak
434of cache pages in readpages causing multiple read oriented stress
435testcases (including fsx, and even large file copy) to fail over time.
436
437Version 1.06
438------------
439Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
440This allows files that differ only in case and improves performance of file
441creation and file open to such servers. Fix semaphore conflict which causes
442slow delete of open file to Samba (which unfortunately can cause an oplock
443break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
444
445Version 1.05
446------------
447fixes to cifs_readpages for fsx test case
448
449Version 1.04
450------------
451Fix caching data integrity bug when extending file size especially when no
452oplock on file. Fix spurious logging of valid already parsed mount options
453that are parsed outside of the cifs vfs such as nosuid.
454
455
456Version 1.03
457------------
458Connect to server when port number override not specified, and tcp port
459unitialized. Reset search to restart at correct file when kernel routine
460filldir returns error during large directory searches (readdir).
461
462Version 1.02
463------------
464Fix caching problem when files opened by multiple clients in which
465page cache could contain stale data, and write through did
466not occur often enough while file was still open when read ahead
467(read oplock) not allowed. Treat "sep=" when first mount option
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700468as an override of comma as the default separator between mount
Linus Torvalds1da177e2005-04-16 15:20:36 -0700469options.
470
471Version 1.01
472------------
473Allow passwords longer than 16 bytes. Allow null password string.
474
475Version 1.00
476------------
477Gracefully clean up failed mounts when attempting to mount to servers such as
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700478Windows 98 that terminate tcp sessions during protocol negotiation. Handle
Linus Torvalds1da177e2005-04-16 15:20:36 -0700479embedded commas in mount parsing of passwords.
480
481Version 0.99
482------------
483Invalidate local inode cached pages on oplock break and when last file
484instance is closed so that the client does not continue using stale local
485copy rather than later modified server copy of file. Do not reconnect
486when server drops the tcp session prematurely before negotiate
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700487protocol response. Fix oops in reopen_file when dentry freed. Allow
Linus Torvalds1da177e2005-04-16 15:20:36 -0700488the support for CIFS Unix Extensions to be disabled via proc interface.
489
490Version 0.98
491------------
492Fix hang in commit_write during reconnection of open files under heavy load.
493Fix unload_nls oops in a mount failure path. Serialize writes to same socket
494which also fixes any possible races when cifs signatures are enabled in SMBs
495being sent out of signature sequence number order.
496
497Version 0.97
498------------
499Fix byte range locking bug (endian problem) causing bad offset and
500length.
501
502Version 0.96
503------------
504Fix oops (in send_sig) caused by CIFS unmount code trying to
505wake up the demultiplex thread after it had exited. Do not log
506error on harmless oplock release of closed handle.
507
508Version 0.95
509------------
510Fix unsafe global variable usage and password hash failure on gcc 3.3.1

571Finish support for Linux 2.5 open/create changes, which removes the
572redundant NTCreate/QPathInfo/close that was sent during file create.
573Enable oplock by default. Enable packet signing by default (needed to
574access many recent Windows servers)
575
576Version 0.83
577------------
578Fix oops when mounting to long server names caused by inverted parms to kmalloc.
579Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
580we will choose a cifs user session (smb uid) that better matches the local
581uid if a) the mount uid does not match the current uid and b) we have another
582session to the same server (ip address) for a different mount which

593Finish up CIFS packet digital signing for the default
594NTLM security case. This should help Windows 2003
595network interoperability since it is common for
596packet signing to be required now. Fix statfs (stat -f)
597which recently started returning errors due to
598invalid value (-1 instead of 0) being set in the
599struct kstatfs f_ffiles field.
600

613Fixed various incorrect or misleading smb to posix error code mappings.
614
615Version 0.77
616------------
617Fix display of NTFS DFS junctions to display as symlinks.
618They are the network equivalent. Fix oops in
619cifs_partialpagewrite caused by missing spinlock protection
620of openfile linked list. Allow writebehind caching errors to
621be returned to the application at file close.
622
623Version 0.76
624------------
625Clean up options displayed in /proc/mounts by show_options to
626be more consistent with other filesystems.
627
628Version 0.75

631presence or absence of read only dos attribute in mode
632bits for servers that do not support CIFS Unix extensions.
633Fix shortened results on readdir of large directories to
634servers supporting CIFS Unix extensions (caused by
635incorrect resume key).
636
637Version 0.74
638------------
639Fix truncate bug (set file size) that could cause hangs e.g. running fsx
640
641Version 0.73

656symlink routines.
657
658Version 0.70
659------------
660Fix oops in get dfs referral (triggered when null path sent in to
661mount). Add support for overriding rsize at mount time.
662
663Version 0.69
664------------
665Fix buffer overrun in readdir which caused intermittent kernel oopses.
666Fix writepage code to release kmap on write data. Allow "-ip=" new
667mount option to be passed in on parameter distinct from the first part
668(server name portion of) the UNC name. Allow override of the
669tcp port of the target server via new mount option "-port="
670
671Version 0.68
672------------
673Fix search handle leak on rewind. Fix setuid and gid so that they are
674reflected in the local inode immediately. Cleanup of whitespace
675to make 2.4 and 2.5 versions more consistent.
676
677
678Version 0.67
679------------
680Fix signal sending so that captive thread (cifsd) exits on umount
681(which was causing the warning in kmem_cache_free of the request buffers
682at rmmod time). This had broken as a sideeffect of the recent global
683kernel change to daemonize. Fix memory leak in readdir code which
684showed up in "ls -R" (and applications that did search rewinding).
685
686Version 0.66
687------------
688Reconnect tids and fids after session reconnection (still do not
689reconnect byte range locks though). Fix problem caching
690lookup information for directory inodes, improving performance,
691especially in deep directory trees. Fix various build warnings.
692
693Version 0.65
694------------
695Finish fixes to commit write for caching/readahead consistency. fsx
696now works to Samba servers. Fix oops caused when readahead
697was interrupted by a signal.
698
699Version 0.64
700------------
701Fix data corruption (in partial page after truncate) that caused fsx to
702fail to Windows servers. Cleaned up some extraneous error logging in
703common error paths. Add generic sendfile support.
704
705Version 0.63
706------------
707Fix memory leak in AllocMidQEntry.
708Finish reconnection logic, so connection with server can be dropped
709(or server rebooted) and the cifs client will reconnect.
710
711Version 0.62
712------------
713Fix temporary socket leak when bad userid or password specified
714(or other SMBSessSetup failure). Increase maximum buffer size to slightly

716sizes. Add support for readpages
717
718Version 0.61
719------------
720Fix oops when username not passed in on mount. Extensive fixes and improvements
721to error logging (strip redundant newlines, change debug macros to ensure newline
722passed in and to be more consistent). Fix writepage wrong file handle problem,
723a readonly file handle could be incorrectly used to attempt to write out
724file updates through the page cache to multiply open files. This could cause
725the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
726shares to the same Windows server when using different usernames
727(doing this to Samba servers worked but Windows was rejecting it) - now it is
728possible to use different userids when connecting to the same server from a
729Linux client. Fix oops when treeDisconnect called during unmount on
730previously freed socket.
731
732Version 0.60
733------------

744Changed read and write to go through pagecache. Added additional address space operations.
745Memory mapped operations now working.
746
747Version 0.57
748------------
749Added writepage code for additional memory mapping support. Fixed leak in xids causing

763Version 0.54
764------------
765Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
766changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
767buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
768
769Version 0.53
770------------
771More stylistic updates to better match kernel style. Add additional statistics
772for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
773and CIFS Packet Signing enablement.
774
775Version 0.52
776------------
777Replace call to sleep_on with safer wait_on_event.

782------------
783Update mount so the -unc mount option is no longer required (the ip address can be specified
784in a UNC style device name. Implementation of readpage/writepage started.
785

787------------
788Fix intermittent problem with incorrect smb header checking on badly
789fragmented tcp responses
790
791Version 0.49
792------------
793Fixes to setting of allocation size and file size.
794

821------------
822SessionSetup and NegotiateProtocol now work from Big Endian machines.
823Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older
824versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7).
825
826Version 0.41
827------------
828Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700829files now return the correct number of links on fstat as they are repeatedly linked and unlinked.
Linus Torvalds1da177e2005-04-16 15:20:36 -0700830
831Version 0.40
832------------
833Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
834session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
835Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
836(which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).

838Version 0.38
839------------
840Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
841it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
842
843Version 0.37
844------------
845Rewrote much of connection and mount/unmount logic to handle bugs with
846multiple uses to same share, multiple users to same server etc.
847
848Version 0.36
849------------
850Fixed major problem with dentry corruption (missing call to dput)
851
852Version 0.35
853------------
854Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
855Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
856although corresponding function not fully implemented in the vfs yet
857
858Version 0.34
859------------
860Fixed dentry caching bug, misc. cleanup
861
862Version 0.33
863------------
864Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
865on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
866Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
867
868Version 0.32
869------------
870Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
871and tested against Samba 2.2.5
872
873
874Version 0.31
875------------
8761) Fixed lockrange to be correct (it was one byte too short)
877
8782) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
879show range as locked when there is a conflict with an existing lock.
880
8813) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
882in most cases. Eventually will offer optional ability to query server for the correct perms.
883
8843) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
885but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
886session)
887
8884) Fixed error logging of valid mount options
889
8905) Removed logging of password field.
891
8926) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
893and cleaned them up and made them more consistent with other cifs functions.
894
8957) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700896(with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
Linus Torvalds1da177e2005-04-16 15:20:36 -0700897nor is the symlink support using the Unix extensions
898
8998) Started adding the readlink and follow_link code
