2------------
3Fix append problem to Samba servers (files opened with O_APPEND could
4have duplicated data). Fix oops in cifs_lookup. Workaround problem
5mounting to OS/400 Netserve. Fix oops in cifs_get_tcp_session.
6Disable use of server inode numbers when server only
7partially supports them (e.g. for one server querying inode numbers on
8FindFirst fails but QPathInfo queries works).

11-------------
12Fix memory leak in reconnect. Fix oops in DFS mount error path.
13Set s_maxbytes to smaller (the max that vfs can handle) so that
Steve Frenchd0985642009-08-04 03:53:28 +000014sendfile will now work over cifs mounts again. Add noforcegid
Steve Frenchca43e3b2009-09-01 17:20:50 +000015and noforceuid mount parameters. Fix small mem leak when using
16ntlmv2. Fix 2nd mount to same server but with different port to
17be allowed (rather than reusing the 1st port) - only when the
18user explicitly overrides the port on the 2nd mount.

Steve Frenchc5077ec2009-05-28 15:09:04 +000020Version 1.59
21------------
22Client uses server inode numbers (which are persistent) rather than
23client generated ones by default (mount option "serverino" turned
Steve Frenchf0472d02009-06-06 21:09:39 +000024on by default if server supports it). Add forceuid and forcegid
25mount options (so that when negotiating unix extensions specifying
26which uid mounted does not immediately force the server's reported
Steve Frenchb77863b2009-07-09 22:51:38 +000027uids to be overridden). Add support for scope mount parm. Improve
28hard link detection to use same inode for both. Do not set
29read-only dos attribute on directories (for chmod) since Windows
30explorer special cases this attribute bit for directories for
31a different purpose.
Steve Frenchc5077ec2009-05-28 15:09:04 +000032
Steve Frenchff694522009-04-20 19:45:13 +000033Version 1.58
34------------
35Guard against buffer overruns in various UCS-2 to UTF-8 string conversions
36when the UTF-8 string is composed of unusually long (more than 4 byte) converted
Steve Frenchd185cda2009-04-30 17:45:10 +000037characters. Add support for mounting root of a share which redirects immediately
38to DFS target. Convert string conversion functions from Unicode to more
39accurately mark string length before allocating memory (which may help the
40rare cases where a UTF-8 string is much larger than the UCS2 string that
Steve Frenche836f012009-05-01 16:20:35 +000041we converted from). Fix endianness of the vcnum field used during
42session setup to distinguish multiple mounts to same server from different
Steve French0b3cc852009-05-04 08:37:12 +000043userids. Raw NTLMSSP fixed (it requires /proc/fs/cifs/experimental
44flag to be set to 2, and mount must enable krb5 to turn on extended security).
Steve Frenchc5077ec2009-05-28 15:09:04 +000045Performance of file create to Samba improved (posix create on lookup
46removes 1 of 2 network requests sent on file create)
Steve Frenchff694522009-04-20 19:45:13 +000047
Steve Frencheca6acf2009-02-20 05:43:09 +000048Version 1.57
49------------
50Improve support for multiple security contexts to the same server. We
51used to use the same "vcnumber" for all connections which could cause
52the server to treat subsequent connections, especially those that
53are authenticated as guest, as reconnections, invalidating the earlier
54user's smb session. This fix allows cifs to mount multiple times to the
55same server with different userids without risking invalidating earlier
Steve Frenchb298f222009-02-21 21:17:43 +000056established security contexts. fsync now sends SMB Flush operation
57to better ensure that we wait for server to write all of the data to
Steve Frenchbe652442009-02-23 15:21:59 +000058server disk (not just write it over the network). Add new mount
59parameter to allow user to disable sending the (slow) SMB flush on
60fsync if desired (fsync still flushes all cached write data to the server).
Steve French64cc2c62009-03-04 19:54:08 +000061Posix file open support added (turned off after one attempt if server
62fails to support it properly, as with Samba server versions prior to 3.3.2)
Steve Frenchb363b332009-03-18 05:57:22 +000063Fix "redzone overwritten" bug in cifs_put_tcon (CIFSTcon may allocate too
64little memory for the "nativeFileSystem" field returned by the server
Steve French85a6dac2009-04-01 05:22:00 +000065during mount). Endian convert inode numbers if necessary (makes it easier
66to compare inode numbers on network files from big endian systems).
Steve Frencheca6acf2009-02-20 05:43:09 +000067
Steve French13a6e422008-12-02 17:24:33 +000068Version 1.56
69------------
70Add "forcemandatorylock" mount option to allow user to use mandatory
71rather than posix (advisory) byte range locks, even though server would
Steve French8be0ed42008-12-05 19:14:12 +000072support posix byte range locks. Fix query of root inode when prefixpath
73specified and user does not have access to query information about the
Steve Frenchc6fbba02008-12-18 01:41:20 +000074top of the share. Fix problem in 2.6.28 resolving DFS paths to
Steve French42c24542009-01-13 22:03:55 +000075Samba servers (worked to Windows). Fix rmdir so that pending search
76(readdir) requests do not get invalid results which include the now
Steve French69765522009-02-17 01:29:40 +000077removed directory. Fix oops in cifs_dfs_ref.c when prefixpath is not reachable
Steve Frenchc3b2a0c2009-02-20 04:32:45 +000078when using DFS. Add better file create support to servers which support
79the CIFS POSIX protocol extensions (this adds support for new flags
80on create, and improves semantics for write of locked ranges).
Steve French13a6e422008-12-02 17:24:33 +000081
Steve French32709582008-10-20 00:44:19 +000082Version 1.55
83------------
84Various fixes to make delete of open files behavior more predictable
85(when delete of an open file fails we mark the file as "delete-on-close"
86in a way that more servers accept, but only if we can first rename the
Steve French84210e92008-10-23 04:42:37 +000087file to a temporary name). Add experimental support for more safely
Steve Frenchedf1ae42008-10-29 00:47:57 +000088handling fcntl(F_SETLEASE). Convert cifs to using blocking tcp
89sends, and also let tcp autotune the socket send and receive buffers.
90This reduces the number of EAGAIN errors returned by TCP/IP in
91high stress workloads (and the number of retries on socket writes
Steve Frenchbfb59822008-11-18 16:33:48 +000092when sending large SMBWriteX requests). Fix case in which a portion of
93data can in some cases not get written to the file on the server before the
94file is closed. Fix DFS parsing to properly handle path consumed field,
95and to handle certain codepage conversions better. Fix mount and
96umount race that can cause oops in mount or umount or reconnect.
Steve French32709582008-10-20 00:44:19 +000097
Steve French26b994f2008-08-06 05:11:33 +000098Version 1.54
99------------
100Fix premature write failure on congested networks (we would give up
101on EAGAIN from the socket too quickly on large writes).
102Cifs_mkdir and cifs_create now respect the setgid bit on parent dir.
103Fix endian problems in acl (mode from/to cifs acl) on bigendian
Steve French6ce5eec2008-08-26 00:37:14 +0000104architectures. Fix problems with preserving timestamps on copying open
105files (e.g. "cp -a") to Windows servers. For mkdir and create honor setgid bit
106on parent directory when server supports Unix Extensions but not POSIX
107create. Update cifs.upcall version to handle new Kerberos sec flags
Jeff Layton87ed1d62008-08-27 17:53:30 +0000108(this requires update of cifs.upcall program from Samba). Fix memory leak
Steve French2e655022008-08-28 15:30:06 +0000109on dns_upcall (resolving DFS referralls). Fix plain text password
110authentication (requires setting SecurityFlags to 0x30030 to enable
111lanman and plain text though). Fix writes to be at correct offset when
112file is open with O_APPEND and file is on a directio (forcediretio) mount.
Steve French32709582008-10-20 00:44:19 +0000113Fix bug in rewinding readdir directory searches. Add nodfs mount option.
Steve French26b994f2008-08-06 05:11:33 +0000114
Steve French39da9842008-04-28 04:04:34 +0000115Version 1.53
116------------
Steve French0e4bbde2008-05-20 19:50:46 +0000117DFS support added (Microsoft Distributed File System client support needed
118for referrals which enable a hierarchical name space among servers).
Steve Frenchdbdbb872008-06-10 21:21:56 +0000119Disable temporary caching of mode bits to servers which do not support
120storing of mode (e.g. Windows servers, when client mounts without cifsacl
121mount option) and add new "dynperm" mount option to enable temporary caching
122of mode (enable old behavior). Fix hang on mount caused when server crashes
123tcp session during negotiate protocol.
Steve French39da9842008-04-28 04:04:34 +0000124
Steve Frenchce06c9f2007-11-08 21:12:01 +0000125Version 1.52
126------------
Jeff Layton9b8f5f52007-11-09 23:25:04 +0000127Fix oops on second mount to server when null auth is used.
Jeff Laytoncea21802007-11-20 23:19:03 +0000128Enable experimental Kerberos support. Return writebehind errors on flush
129and sync so that events like out of disk space get reported properly on
Jeff Layton1d9a8852007-12-31 01:37:11 +0000130cached files. Fix setxattr failure to certain Samba versions. Fix mount
131of second share to disconnected server session (autoreconnect on this).
Steve French97837582007-12-31 07:47:21 +0000132Add ability to modify cifs acls for handling chmod (when mounted with
Steve French03a143c2008-02-14 06:38:30 +0000133cifsacl flag). Fix prefixpath path separator so we can handle mounts
134with prefixpaths longer than one directory (one path component) when
Steve French932e2d22008-04-04 21:59:35 +0000135mounted to Windows servers. Fix slow file open when cifsacl
Jeff Layton63534502008-05-12 19:56:05 -0700136enabled. Fix memory leak in FindNext when the SMB call returns -EBADF.

Steve Frenchce06c9f2007-11-08 21:12:01 +0000138
Steve French407f61a2007-09-28 06:53:39 +0000139Version 1.51
140------------
141Fix memory leak in statfs when mounted to very old servers (e.g.
Steve French92ad9b92007-09-29 05:21:58 +0000142Windows 9x). Add new feature "POSIX open" which allows servers
143which support the current POSIX Extensions to provide better semantics
144(e.g. delete for open files opened with posix open). Take into
145account umask on posix mkdir not just older style mkdir. Add
146ability to mount to IPC$ share (which allows CIFS named pipes to be
Steve French297647c2007-10-12 04:11:59 +0000147opened, read and written as if they were files). When 1st tree
148connect fails (e.g. due to signing negotiation failure) fix
149leak that causes cifsd not to stop and rmmod to fail to cleanup
Cyril Gorcunov8f2376a2007-10-14 17:58:43 +0000150cifs_request_buffers pool. Fix problem with POSIX Open/Mkdir on
Steve Frenchc18c7322007-10-17 18:01:11 +0000151bigendian architectures. Fix possible memory corruption when
Steve Frenchabb63d62007-10-18 02:58:40 +0000152EAGAIN returned on kern_recvmsg. Return better error if server
Shirish Pargaonkare01b6402007-10-30 04:45:14 +0000153requires packet signing but client has disabled it. When mounted
154with cifsacl mount option - mode bits are approximated based
Steve French1fb64bf2007-11-01 02:12:10 +0000155on the contents of the ACL of the file or directory. When cifs
156mount helper is missing convert make sure that UNC name
157has backslash (not forward slash) between ip address of server
158and the share name.
Steve French407f61a2007-09-28 06:53:39 +0000159
Steve Frenchb609f062007-07-09 07:55:14 +0000160Version 1.50
161------------
Steve French7521a3c2007-07-11 18:30:34 +0000162Fix NTLMv2 signing. NFS server mounted over cifs works (if cifs mount is
Steve French2d785a52007-07-15 01:48:57 +0000163done with "serverino" mount option). Add support for POSIX Unlink
164(helps with certain sharing violation cases when server such as
Steve Frencha403a0a2007-07-26 15:54:16 +0000165Samba supports newer POSIX CIFS Protocol Extensions). Add "nounix"
166mount option to allow disabling the CIFS Unix Extensions for just
167that mount. Fix hang on spinlock in find_writable_file (race when
Jeff Layton39db8102007-08-24 03:16:51 +0000168reopening file after session crash). Byte range unlock request to
169windows server could unlock more bytes (on server copy of file)
170than intended if start of unlock request is well before start of
171a previous byte range lock that we issued.
Steve Frenchb609f062007-07-09 07:55:14 +0000172
Steve French5858ae42007-04-25 11:59:10 +0000173Version 1.49
174------------
175IPv6 support. Enable ipv6 addresses to be passed on mount (put the ipv6
176address after the "ip=" mount option, at least until mount.cifs is fixed to
Steve French4523cc32007-04-30 20:13:06 +0000177handle DNS host to ipv6 name translation). Accept override of uid or gid
178on mount even when Unix Extensions are negotiated (it used to be ignored
179when Unix Extensions were ignored). This allows users to override the
180default uid and gid for files when they are certain that the uids or
Jeff Layton8426c392007-05-05 03:27:49 +0000181gids on the server do not match those of the client. Make "sec=none"
182mount override username (so that null user connection is attempted)
Steve French75865f82007-06-24 18:30:48 +0000183to match what documentation said. Support for very large reads, over 127K,
184available to some newer servers (such as Samba 3.0.26 and later but
185note that it also requires setting CIFSMaxBufSize at module install
186time to a larger value which may hurt performance in some cases).
Jeff38c10a12007-07-06 21:10:07 +0000187Make sign option force signing (or fail if server does not support it).
Steve French5858ae42007-04-25 11:59:10 +0000188
189Version 1.48
Steve French3677db12007-02-26 16:46:11 +0000190------------
191Fix mtime bouncing around from local idea of last write times to remote time.
192Fix hang (in i_size_read) when simultaneous size update of same remote file
Steve French8a236262007-03-06 00:31:00 +0000193on smp system corrupts sequence number. Do not reread unnecessarily partial page
194(which we are about to overwrite anyway) when writing out file opened rw.
Alan Tysonf5c1e2e2007-03-10 06:05:14 +0000195When DOS attribute of file on non-Unix server's file changes on the server side
196from read-only back to read-write, reflect this change in default file mode
Steve French066fcb02007-03-23 00:45:08 +0000197(we had been leaving a file's mode read-only until the inode were reloaded).
198Allow setting of attribute back to ATTR_NORMAL (removing readonly dos attribute
199when archive dos attribute not set and we are changing mode back to writeable
Steve French5268df22007-04-06 19:28:16 +0000200on server which does not support the Unix Extensions). Remove read only dos
201attribute on chmod when adding any write permission (ie on any of
202user/group/other (not all of user/group/other ie 0222) when
Steve French2dd29d32007-04-23 22:07:35 +0000203mounted to windows. Add support for POSIX MkDir (slight performance
204enhancement and eliminates the network race between the mkdir and set
205path info of the mode).

Steve French595dcfe2007-02-08 18:11:42 +0000211Fix file corruption which could occur on some large file
212copies caused by writepages page i/o completion bug.
Steve Frencha8507902007-02-06 20:43:30 +0000213Seek to SEEK_END forces check for update of file size for non-cached
Steve French8af18972007-02-14 04:42:51 +0000214files. Allow file size to be updated on remote extend of locally open,
215non-cached file. Fix reconnect to newer Samba servers (or other servers
216which support the CIFS Unix/POSIX extensions) so that we again tell the
217server the Unix/POSIX cifs capabilities which we support (SetFSInfo).
218Add experimental support for new POSIX Open/Mkdir (which returns
219stat information on the open, and allows setting the mode).

Steve French4b952a92006-10-30 21:46:13 +0000224Allow null user to be specified on mount ("username="). Do not return
225EINVAL on readdir when filldir fails due to overwritten blocksize
Steve French8e87d4d2006-11-02 03:45:24 +0000226(fixes FC problem). Return error in rename 2nd attempt retry (ie report

Steve French33ec32f2006-12-08 04:14:28 +0000228not reporting whether the retry worked or not). Fix NTLMv2 to

234time out requests if server still responding reasonably fast
Steve Frenche466e482006-08-15 13:07:18 +0000235on requests on other threads. Improve POSIX locking emulation,
236(lock cancel now works, and unlock of merged range works even
237to Windows servers now). Fix oops on mount to lanman servers
Steve Frenchea4c07d2006-08-16 19:44:25 +0000238(win9x, os/2 etc.) when null password. Do not send listxattr
Steve French2fe87f02006-09-21 07:02:52 +0000239(SMB to query all EAs) if nouser_xattr specified. Fix SE Linux

244Rewritten sessionsetup support, including support for legacy SMB
245session setup needed for OS/2 and older servers such as Windows 95 and 98.
Steve French5bafd762006-06-07 00:18:43 +0000246Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
247so we can do search (ls etc.) to OS/2. Do not send NTCreateX
248or recent levels of FindFirst unless server says it supports NT SMBs
Steve French1717ffc2006-06-08 05:41:32 +0000249(instead use legacy equivalents from LANMAN dialect). Fix to allow

Steve Frencha878fb22006-05-30 18:04:19 +0000257(disabled by default controlled by proc/fs/cifs/Experimental).
258Handle conversion of long share names (especially Asian languages)
Steve French26a21b92006-05-31 18:05:34 +0000259to Unicode during mount. Fix memory leak in sess struct on reconnect.
260Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
261cifs open which helps rare case when setpathinfo fails or server does
262not support it.

Steve French12b3b8f2006-02-09 21:12:47 +0000273Version 1.41
274------------
275Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
276configure stronger authentication. Fix sfu symlinks so they can
Steve French184ed212006-02-24 06:15:11 +0000277be followed (not just recognized). Fix wraparound of bcc on
278read responses when buffer size over 64K and also fix wrap of
279max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
280cifs_user_read and cifs_readpages (when EAGAIN on send of smb
Steve French08547b02006-02-28 22:39:25 +0000281on socket is returned over and over). Add POSIX (advisory) byte range
282locking support (requires server with newest CIFS UNIX Extensions
Steve French083d3a22006-03-03 09:53:36 +0000283to the protocol implemented). Slow down negprot slightly in port 139
284RFC1001 case to give session_init time on buggy servers.

287------------
Steve French84afc292005-12-02 13:32:45 -0800288Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
Steve French0a4b92c2006-01-12 15:44:21 -0800289of readpages by eliminating one extra memcpy. Allow update of file size
290from remote server even if file is open for write as long as mount is
Steve Frencheeac8042006-01-13 21:34:58 -0800291directio. Recognize share mode security and send NTLM encrypted password
292on tree connect if share mode negotiated.
Steve French83451872005-12-01 17:12:59 -0800293
Steve French23e7dd72005-10-20 13:44:56 -0700294Version 1.39
295------------
Steve French3abb9272005-11-28 08:16:13 -0800296Defer close of a file handle slightly if pending writes depend on that handle
Steve French23e7dd72005-10-20 13:44:56 -0700297(this reduces the EBADF bad file handle errors that can be logged under heavy
Steve French3c50c612005-11-10 17:31:33 -0800298stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
Steve French3abb9272005-11-28 08:16:13 -0800299Fix SFU style symlinks and mknod needed for servers which do not support the
300CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
301dentries so files that the client sees as deleted but that later get created
Steve French6473a552005-11-29 20:20:10 -0800302on the server will be recognized. Add client side permission check on setattr.
Steve French83451872005-12-01 17:12:59 -0800303Timeout stuck requests better (where server has never responded or sent corrupt
304responses)
Steve French23e7dd72005-10-20 13:44:56 -0700305
Steve French190fdeb2005-10-10 11:48:26 -0700306Version 1.38
307------------
308Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
309to be smaller at first (but increasing) so large write performance performance
310over GigE is better. Do not hang thread on illegal byte range lock response
311from Windows (Windows can send an RFC1001 size which does not match smb size) by
312allowing an SMBs TCP length to be up to a few bytes longer than it should be.
313wsize and rsize can now be larger than negotiated buffer size if server
314supports large readx/writex, even when directio mount flag not specified.
315Write size will in many cases now be 16K instead of 4K which greatly helps
Steve French4ca9c192005-10-10 19:52:13 -0700316file copy performance on lightly loaded networks. Fix oops in dnotify
Steve French1047abc2005-10-11 19:58:06 -0700317when experimental config flag enabled. Make cifsFYI more granular.
Steve French190fdeb2005-10-10 11:48:26 -0700318
Steve Frencheafe8702005-09-15 21:47:30 -0700319Version 1.37
320------------
321Fix readdir caching when unlink removes file in current search buffer,
322and this is followed by a rewind search to just before the deleted entry.
Steve Frenche30dcf32005-09-20 20:49:16 -0700323Do not attempt to set ctime unless atime and/or mtime change requested
Steve French20962432005-09-21 22:05:57 -0700324(most servers throw it away anyway). Fix length check of received smbs
Steve French70ca7342005-09-22 16:32:06 -0700325to be more accurate. Fix big endian problem with mapchars mount option,
326and with a field returned by statfs.
Steve Frencheafe8702005-09-15 21:47:30 -0700327
Steve Frenchc46fa8a2005-08-18 20:49:57 -0700328Version 1.36
329------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700330Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
Steve French6b8edfe2005-08-23 20:26:03 -0700331For these older servers, add option for passing netbios name of server in
Steve French16abbec2005-08-30 13:10:14 -0700332on mount (servernetbiosname). Add suspend support for power management, to
333avoid cifsd thread preventing software suspend from working.
Steve Frenchc46fa8a2005-08-18 20:49:57 -0700334Add mount option for disabling the default behavior of sending byte range lock
335requests to the server (necessary for certain applications which break with
336mandatory lock behavior such as Evolution), and also mount option for
337requesting case insensitive matching for path based requests (requesting
338case sensitive is the default).
339
Steve Frenchf4cfd692005-07-14 18:29:02 -0500340Version 1.35
341------------
342Add writepage performance improvements. Fix path name conversions
343for long filenames on mounts which were done with "mapchars" mount option
Steve Frencha10faeb22005-08-22 21:38:31 -0700344specified. Ensure multiplex ids do not collide. Fix case in which
345rmmod can oops if done soon after last unmount. Fix truncated
346search (readdir) output when resume filename was a long filename.
347Fix filename conversion when mapchars mount option was specified and
348filename was a long filename.
Steve Frenchf4cfd692005-07-14 18:29:02 -0500349
Steve French11aa0142005-04-28 22:41:10 -0700350Version 1.34
351------------
352Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
Steve French31ca3bc2005-04-28 22:41:11 -0700353Do not oops if root user kills cifs oplock kernel thread or
354kills the cifsd thread (NB: killing the cifs kernel threads is not
355recommended, unmount and rmmod cifs will kill them when they are
Steve French68575472005-04-30 11:10:57 -0700356no longer needed). Fix readdir to ASCII servers (ie older servers
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700357which do not support Unicode) and also require asterisk.
Steve French3079ca62005-06-09 14:44:07 -0700358Fix out of memory case in which data could be written one page
359off in the page cache.
Steve French11aa0142005-04-28 22:41:10 -0700360
Steve French966ca922005-04-28 22:41:08 -0700361Version 1.33
362------------
363Fix caching problem, in which readdir of directory containing a file
364which was cached could cause the file's time stamp to be updated
365without invalidating the readahead data (so we could get stale
366file data on the client for that file even as the server copy changed).
Steve Frenchcd634992005-04-28 22:41:10 -0700367Cleanup response processing so cifsd can not loop when abnormally
368terminated.
Steve French966ca922005-04-28 22:41:08 -0700369
370
Steve Frenchf654bac2005-04-28 22:41:04 -0700371Version 1.32
Linus Torvalds1da177e2005-04-16 15:20:36 -0700372------------
373Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
374transact response for an SMB request and search entry split across two frames.
Steve Frenchf654bac2005-04-28 22:41:04 -0700375Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
376as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
377unless server explicitly claims to support them in CIFS Unix extensions
Steve Frenchad009ac2005-04-28 22:41:05 -0700378POSIX ACL capability bit. Fix packet signing when multiuser mounting with
Steve Frenchcbe04762005-04-28 22:41:05 -0700379different users from the same client to the same server. Fix oops in
Steve French6a0b4822005-04-28 22:41:05 -0700380cifs_close. Add mount option for remapping reserved characters in
381filenames (also allow recognizing files with created by SFU which have any
Steve French737b7582005-04-28 22:41:06 -0700382of these seven reserved characters, except backslash, to be recognized).
Steve French848f3fc2005-04-28 22:41:07 -0700383Fix invalid transact2 message (we were sometimes trying to interpret
Steve French099a58f2005-04-28 22:41:07 -0700384oplock breaks as SMB responses). Add ioctl for checking that the
385current uid matches the uid of the mounter (needed by umount.cifs).
386Reduce the number of large buffer allocations in cifs response processing
387(significantly reduces memory pressure under heavy stress with multiple
388processes accessing the same server at the same time).
Steve Frenchf654bac2005-04-28 22:41:04 -0700389
390Version 1.31
391------------
Linus Torvalds1da177e2005-04-16 15:20:36 -0700392Fix updates of DOS attributes and time fields so that files on NT4 servers
393do not get marked delete on close. Display sizes of cifs buffer pools in
394cifs stats. Fix oops in unmount when cifsd thread being killed by
395shutdown. Add generic readv/writev and aio support. Report inode numbers
396consistently in readdir and lookup (when serverino mount option is
397specified use the inode number that the server reports - for both lookup
398and readdir, otherwise by default the locally generated inode number is used
399for inodes created in either path since servers are not always able to
400provide unique inode numbers when exporting multiple volumes from under one
401sharename).
402
403Version 1.30
404------------
405Allow new nouser_xattr mount parm to disable xattr support for user namespace.
406Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
407(mostly affects NT4 servers) by retry with handle based network operation.
408Add new POSIX Query FS Info for returning statfs info more accurately.
409Handle passwords with multiple commas in them.
410
411Version 1.29
412------------
413Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
414Fix capabilities flags for large readx so as to allow reads larger than 64K.
415
416Version 1.28
417------------
418Add module init parm for large SMB buffer size (to allow it to be changed
419from its default of 16K) which is especially useful for large file copy
420when mounting with the directio mount option. Fix oops after
421returning from mount when experimental ExtendedSecurity enabled and
422SpnegoNegotiated returning invalid error. Fix case to retry better when
423peek returns from 1 to 3 bytes on socket which should have more data.
424Fixed path based calls (such as cifs lookup) to handle path names
425longer than 530 (now can handle PATH_MAX). Fix pass through authentication
426from Samba server to DC (Samba required dummy LM password).
427
428Version 1.27
429------------
430Turn off DNOTIFY (directory change notification support) by default
431(unless built with the experimental flag) to fix hang with KDE
432file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
433waiting on an SMB response) in SendReceive when session dies but
434reconnects quickly from another task. Add module init parms for
435minimum number of large and small network buffers in the buffer pools,
436and for the maximum number of simultaneous requests.
437
438Version 1.26
439------------
440Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
441and other POSIX CIFS compliant servers. Fix error mapping for getfacl
442to EOPNOTSUPP when server does not support posix acls on the wire. Fix
443improperly zeroed buffer in CIFS Unix extensions set times call.
444
445Version 1.25
446------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700447Fix internationalization problem in cifs readdir with filenames that map to
Alexey Dobriyan4de151d2006-03-22 00:13:35 +0100448longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
Linus Torvalds1da177e2005-04-16 15:20:36 -0700449for readdir to netapp servers. Fix search rewind (seek into readdir to return
450non-consecutive entries). Do not do readdir when server negotiates
451buffer size to small to fit filename. Add support for reading POSIX ACLs from
452the server (add also acl and noacl mount options).
453
454Version 1.24
455------------
456Optionally allow using server side inode numbers, rather than client generated
457ones by specifying mount option "serverino" - this is required for some apps
458to work which double check hardlinked files and have persistent inode numbers.
459
460Version 1.23
461------------
462Multiple bigendian fixes. On little endian systems (for reconnect after
463network failure) fix tcp session reconnect code so we do not try first
464to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
465as directories rather than symlinks because we can do follow link on them.
466
467Version 1.22
468------------
469Add config option to enable XATTR (extended attribute) support, mapping
470xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
471minor fixes pointed out by the Stanford SWAT checker (mostly missing
472or out of order NULL pointer checks in little used error paths).
473
474Version 1.21
475------------
476Add new mount parm to control whether mode check (generic_permission) is done
477on the client. If Unix extensions are enabled and the uids on the client
478and server do not match, client permission checks are meaningless on
479server uids that do not exist on the client (this does not affect the
480normal ACL check which occurs on the server). Fix default uid
481on mknod to match create and mkdir. Add optional mount parm to allow
482override of the default uid behavior (in which the server sets the uid
483and gid of newly created files). Normally for network filesystem mounts
484user want the server to set the uid/gid on newly created files (rather than
485using uid of the client processes you would in a local filesystem).
486
487Version 1.20
488------------
489Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
490info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
491(in build_wildcard_path_from_dentry). Fix mknod to pass type field
492(block/char/fifo) properly. Remove spurious mount warning log entry when
493credentials passed as mount argument. Set major/minor device number in
494inode for block and char devices when unix extensions enabled.
495
496Version 1.19
497------------
498Fix /proc/fs/cifs/Stats and DebugData display to handle larger
499amounts of return data. Properly limit requests to MAX_REQ (50
500is the usual maximum active multiplex SMB/CIFS requests per server).
501Do not kill cifsd (and thus hurt the other SMB session) when more than one
502session to the same server (but with different userids) exists and one
503of the two user's smb sessions is being removed while leaving the other.
504Do not loop reconnecting in cifsd demultiplex thread when admin
505kills the thread without going through unmount.
506
507Version 1.18
508------------
509Do not rename hardlinked files (since that should be a noop). Flush
510cached write behind data when reopening a file after session abend,
511except when already in write. Grab per socket sem during reconnect
512to avoid oops in sendmsg if overlapping with reconnect. Do not
513reset cached inode file size on readdir for files open for write on
514client.
515
516
517Version 1.17
518------------
519Update number of blocks in file so du command is happier (in Linux a fake
520blocksize of 512 is required for calculating number of blocks in inode).
521Fix prepare write of partial pages to read in data from server if possible.
522Fix race on tcpStatus field between unmount and reconnection code, causing
523cifsd process sometimes to hang around forever. Improve out of memory
524checks in cifs_filldir
525
526Version 1.16
527------------
528Fix incorrect file size in file handle based setattr on big endian hardware.
529Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
530and closing file structs in writepage/partialpagewrite. Add statistics
531for each mounted share (new menuconfig option). Fix endianness problem in
532volume information displayed in /proc/fs/cifs/DebugData (only affects
533affects big endian architectures). Prevent renames while constructing
534path names for open, mkdir and rmdir.
535
536Version 1.15
537------------
538Change to mempools for alloc smb request buffers and multiplex structs
539to better handle low memory problems (and potential deadlocks).
540
541Version 1.14
542------------
543Fix incomplete listings of large directories on Samba servers when Unix
544extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
545rename deadlock when writing out dirty pages at same time.
546
547Version 1.13
548------------
549Fix open of files in which O_CREATE can cause the mode to change in
550some cases. Fix case in which retry of write overlaps file close.
551Fix PPC64 build error. Reduce excessive stack usage in smb password
552hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
553
554Version 1.12
555------------
556Fixes for large file copy, signal handling, socket retry, buffer
557allocation and low memory situations.
558
559Version 1.11
560------------
561Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
562also now allowing support for specifying client netbiosname. NT4 support added.
563
564Version 1.10
565------------
566Fix reconnection (and certain failed mounts) to properly wake up the
567blocked users thread so it does not seem hung (in some cases was blocked
568until the cifs receive timeout expired). Fix spurious error logging
569to kernel log when application with open network files killed.
570
571Version 1.09
572------------
573Fix /proc/fs module unload warning message (that could be logged
574to the kernel log). Fix intermittent failure in connectathon
575test7 (hardlink count not immediately refreshed in case in which
576inode metadata can be incorrectly kept cached when time near zero)
577
578Version 1.08
579------------
580Allow file_mode and dir_mode (specified at mount time) to be enforced
581locally (the server already enforced its own ACLs too) for servers
582that do not report the correct mode (do not support the
583CIFS Unix Extensions).
584
585Version 1.07
586------------
587Fix some small memory leaks in some unmount error paths. Fix major leak
588of cache pages in readpages causing multiple read oriented stress
589testcases (including fsx, and even large file copy) to fail over time.
590
591Version 1.06
592------------
593Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
594This allows files that differ only in case and improves performance of file
595creation and file open to such servers. Fix semaphore conflict which causes
596slow delete of open file to Samba (which unfortunately can cause an oplock
597break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
598
599Version 1.05
600------------
601fixes to cifs_readpages for fsx test case
602
603Version 1.04
604------------
605Fix caching data integrity bug when extending file size especially when no
606oplock on file. Fix spurious logging of valid already parsed mount options
607that are parsed outside of the cifs vfs such as nosuid.
608
609
610Version 1.03
611------------
612Connect to server when port number override not specified, and tcp port
613unitialized. Reset search to restart at correct file when kernel routine
614filldir returns error during large directory searches (readdir).
615
616Version 1.02
617------------
618Fix caching problem when files opened by multiple clients in which
619page cache could contain stale data, and write through did
620not occur often enough while file was still open when read ahead
621(read oplock) not allowed. Treat "sep=" when first mount option
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700622as an override of comma as the default separator between mount
Linus Torvalds1da177e2005-04-16 15:20:36 -0700623options.
624
625Version 1.01
626------------
627Allow passwords longer than 16 bytes. Allow null password string.
628
629Version 1.00
630------------
631Gracefully clean up failed mounts when attempting to mount to servers such as
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700632Windows 98 that terminate tcp sessions during protocol negotiation. Handle
Linus Torvalds1da177e2005-04-16 15:20:36 -0700633embedded commas in mount parsing of passwords.
634
635Version 0.99
636------------
637Invalidate local inode cached pages on oplock break and when last file
638instance is closed so that the client does not continue using stale local
639copy rather than later modified server copy of file. Do not reconnect
640when server drops the tcp session prematurely before negotiate
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700641protocol response. Fix oops in reopen_file when dentry freed. Allow
Linus Torvalds1da177e2005-04-16 15:20:36 -0700642the support for CIFS Unix Extensions to be disabled via proc interface.
643
644Version 0.98
645------------
646Fix hang in commit_write during reconnection of open files under heavy load.
647Fix unload_nls oops in a mount failure path. Serialize writes to same socket
648which also fixes any possible races when cifs signatures are enabled in SMBs
649being sent out of signature sequence number order.
650
651Version 0.97
652------------
653Fix byte range locking bug (endian problem) causing bad offset and
654length.
655
656Version 0.96
657------------

830
831
832Version 0.67
833------------
834Fix signal sending so that captive thread (cifsd) exits on umount
835(which was causing the warning in kmem_cache_free of the request buffers
836at rmmod time). This had broken as a sideeffect of the recent global
837kernel change to daemonize. Fix memory leak in readdir code which
838showed up in "ls -R" (and applications that did search rewinding).
839

873------------
874Fix oops when username not passed in on mount. Extensive fixes and improvements
875to error logging (strip redundant newlines, change debug macros to ensure newline
876passed in and to be more consistent). Fix writepage wrong file handle problem,
877a readonly file handle could be incorrectly used to attempt to write out
878file updates through the page cache to multiply open files. This could cause
879the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
880shares to the same Windows server when using different usernames
881(doing this to Samba servers worked but Windows was rejecting it) - now it is
882possible to use different userids when connecting to the same server from a
883Linux client. Fix oops when treeDisconnect called during unmount on
884previously freed socket.

1037
10383) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
1039but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
1040session)
1041
10424) Fixed error logging of valid mount options
1043
10445) Removed logging of password field.
1045
10466) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
