2-------------
3Fix memory leak in reconnect. Fix oops in DFS mount error path.
4Set s_maxbytes to smaller (the max that vfs can handle) so that
Steve Frenchd0985642009-08-04 03:53:28 +00005sendfile will now work over cifs mounts again. Add noforcegid
6and noforceuid mount parameters.

Steve Frenchc5077ec2009-05-28 15:09:04 +00008Version 1.59
9------------
10Client uses server inode numbers (which are persistent) rather than
11client generated ones by default (mount option "serverino" turned
Steve Frenchf0472d02009-06-06 21:09:39 +000012on by default if server supports it). Add forceuid and forcegid
13mount options (so that when negotiating unix extensions specifying
14which uid mounted does not immediately force the server's reported
Steve Frenchb77863b2009-07-09 22:51:38 +000015uids to be overridden). Add support for scope mount parm. Improve
16hard link detection to use same inode for both. Do not set
17read-only dos attribute on directories (for chmod) since Windows
18explorer special cases this attribute bit for directories for
19a different purpose.

Steve Frenchff694522009-04-20 19:45:13 +000021Version 1.58
22------------
23Guard against buffer overruns in various UCS-2 to UTF-8 string conversions
24when the UTF-8 string is composed of unusually long (more than 4 byte) converted
Steve Frenchd185cda2009-04-30 17:45:10 +000025characters. Add support for mounting root of a share which redirects immediately
26to DFS target. Convert string conversion functions from Unicode to more
27accurately mark string length before allocating memory (which may help the
28rare cases where a UTF-8 string is much larger than the UCS2 string that
Steve Frenche836f012009-05-01 16:20:35 +000029we converted from). Fix endianness of the vcnum field used during
30session setup to distinguish multiple mounts to same server from different
Steve French0b3cc852009-05-04 08:37:12 +000031userids. Raw NTLMSSP fixed (it requires /proc/fs/cifs/experimental
32flag to be set to 2, and mount must enable krb5 to turn on extended security).
Steve Frenchc5077ec2009-05-28 15:09:04 +000033Performance of file create to Samba improved (posix create on lookup
34removes 1 of 2 network requests sent on file create)
Steve Frenchff694522009-04-20 19:45:13 +000035
Steve Frencheca6acf2009-02-20 05:43:09 +000036Version 1.57
37------------
38Improve support for multiple security contexts to the same server. We
39used to use the same "vcnumber" for all connections which could cause
40the server to treat subsequent connections, especially those that
41are authenticated as guest, as reconnections, invalidating the earlier
42user's smb session. This fix allows cifs to mount multiple times to the
43same server with different userids without risking invalidating earlier
Steve Frenchb298f222009-02-21 21:17:43 +000044established security contexts. fsync now sends SMB Flush operation
45to better ensure that we wait for server to write all of the data to
Steve Frenchbe652442009-02-23 15:21:59 +000046server disk (not just write it over the network). Add new mount
47parameter to allow user to disable sending the (slow) SMB flush on
48fsync if desired (fsync still flushes all cached write data to the server).
Steve French64cc2c62009-03-04 19:54:08 +000049Posix file open support added (turned off after one attempt if server
50fails to support it properly, as with Samba server versions prior to 3.3.2)
Steve Frenchb363b332009-03-18 05:57:22 +000051Fix "redzone overwritten" bug in cifs_put_tcon (CIFSTcon may allocate too
52little memory for the "nativeFileSystem" field returned by the server
Steve French85a6dac2009-04-01 05:22:00 +000053during mount). Endian convert inode numbers if necessary (makes it easier
54to compare inode numbers on network files from big endian systems).
Steve Frencheca6acf2009-02-20 05:43:09 +000055
Steve French13a6e422008-12-02 17:24:33 +000056Version 1.56
57------------
58Add "forcemandatorylock" mount option to allow user to use mandatory
59rather than posix (advisory) byte range locks, even though server would
Steve French8be0ed42008-12-05 19:14:12 +000060support posix byte range locks. Fix query of root inode when prefixpath
61specified and user does not have access to query information about the
Steve Frenchc6fbba02008-12-18 01:41:20 +000062top of the share. Fix problem in 2.6.28 resolving DFS paths to
Steve French42c24542009-01-13 22:03:55 +000063Samba servers (worked to Windows). Fix rmdir so that pending search
64(readdir) requests do not get invalid results which include the now
Steve French69765522009-02-17 01:29:40 +000065removed directory. Fix oops in cifs_dfs_ref.c when prefixpath is not reachable
Steve Frenchc3b2a0c2009-02-20 04:32:45 +000066when using DFS. Add better file create support to servers which support
67the CIFS POSIX protocol extensions (this adds support for new flags
68on create, and improves semantics for write of locked ranges).
Steve French13a6e422008-12-02 17:24:33 +000069
Steve French32709582008-10-20 00:44:19 +000070Version 1.55
71------------
72Various fixes to make delete of open files behavior more predictable
73(when delete of an open file fails we mark the file as "delete-on-close"
74in a way that more servers accept, but only if we can first rename the
Steve French84210e92008-10-23 04:42:37 +000075file to a temporary name). Add experimental support for more safely
Steve Frenchedf1ae42008-10-29 00:47:57 +000076handling fcntl(F_SETLEASE). Convert cifs to using blocking tcp
77sends, and also let tcp autotune the socket send and receive buffers.
78This reduces the number of EAGAIN errors returned by TCP/IP in
79high stress workloads (and the number of retries on socket writes
Steve Frenchbfb59822008-11-18 16:33:48 +000080when sending large SMBWriteX requests). Fix case in which a portion of
81data can in some cases not get written to the file on the server before the
82file is closed. Fix DFS parsing to properly handle path consumed field,
83and to handle certain codepage conversions better. Fix mount and
84umount race that can cause oops in mount or umount or reconnect.
Steve French32709582008-10-20 00:44:19 +000085
Steve French26b994f2008-08-06 05:11:33 +000086Version 1.54
87------------
88Fix premature write failure on congested networks (we would give up
89on EAGAIN from the socket too quickly on large writes).
90Cifs_mkdir and cifs_create now respect the setgid bit on parent dir.
91Fix endian problems in acl (mode from/to cifs acl) on bigendian
Steve French6ce5eec2008-08-26 00:37:14 +000092architectures. Fix problems with preserving timestamps on copying open
93files (e.g. "cp -a") to Windows servers. For mkdir and create honor setgid bit
94on parent directory when server supports Unix Extensions but not POSIX
95create. Update cifs.upcall version to handle new Kerberos sec flags
Jeff Layton87ed1d62008-08-27 17:53:30 +000096(this requires update of cifs.upcall program from Samba). Fix memory leak
Steve French2e655022008-08-28 15:30:06 +000097on dns_upcall (resolving DFS referralls). Fix plain text password
98authentication (requires setting SecurityFlags to 0x30030 to enable
99lanman and plain text though). Fix writes to be at correct offset when
100file is open with O_APPEND and file is on a directio (forcediretio) mount.
Steve French32709582008-10-20 00:44:19 +0000101Fix bug in rewinding readdir directory searches. Add nodfs mount option.
Steve French26b994f2008-08-06 05:11:33 +0000102
Steve French39da9842008-04-28 04:04:34 +0000103Version 1.53
104------------
Steve French0e4bbde2008-05-20 19:50:46 +0000105DFS support added (Microsoft Distributed File System client support needed
106for referrals which enable a hierarchical name space among servers).
Steve Frenchdbdbb872008-06-10 21:21:56 +0000107Disable temporary caching of mode bits to servers which do not support
108storing of mode (e.g. Windows servers, when client mounts without cifsacl
109mount option) and add new "dynperm" mount option to enable temporary caching
110of mode (enable old behavior). Fix hang on mount caused when server crashes
111tcp session during negotiate protocol.
Steve French39da9842008-04-28 04:04:34 +0000112
Steve Frenchce06c9f2007-11-08 21:12:01 +0000113Version 1.52
114------------
Jeff Layton9b8f5f52007-11-09 23:25:04 +0000115Fix oops on second mount to server when null auth is used.
Jeff Laytoncea21802007-11-20 23:19:03 +0000116Enable experimental Kerberos support. Return writebehind errors on flush
117and sync so that events like out of disk space get reported properly on
Jeff Layton1d9a8852007-12-31 01:37:11 +0000118cached files. Fix setxattr failure to certain Samba versions. Fix mount
119of second share to disconnected server session (autoreconnect on this).
Steve French97837582007-12-31 07:47:21 +0000120Add ability to modify cifs acls for handling chmod (when mounted with
Steve French03a143c2008-02-14 06:38:30 +0000121cifsacl flag). Fix prefixpath path separator so we can handle mounts
122with prefixpaths longer than one directory (one path component) when
Steve French932e2d22008-04-04 21:59:35 +0000123mounted to Windows servers. Fix slow file open when cifsacl
Jeff Layton63534502008-05-12 19:56:05 -0700124enabled. Fix memory leak in FindNext when the SMB call returns -EBADF.

Steve Frenchce06c9f2007-11-08 21:12:01 +0000126
Steve French407f61a2007-09-28 06:53:39 +0000127Version 1.51
128------------
129Fix memory leak in statfs when mounted to very old servers (e.g.
Steve French92ad9b92007-09-29 05:21:58 +0000130Windows 9x). Add new feature "POSIX open" which allows servers
131which support the current POSIX Extensions to provide better semantics
132(e.g. delete for open files opened with posix open). Take into
133account umask on posix mkdir not just older style mkdir. Add
134ability to mount to IPC$ share (which allows CIFS named pipes to be
Steve French297647c2007-10-12 04:11:59 +0000135opened, read and written as if they were files). When 1st tree
136connect fails (e.g. due to signing negotiation failure) fix
137leak that causes cifsd not to stop and rmmod to fail to cleanup
Cyril Gorcunov8f2376a2007-10-14 17:58:43 +0000138cifs_request_buffers pool. Fix problem with POSIX Open/Mkdir on
Steve Frenchc18c7322007-10-17 18:01:11 +0000139bigendian architectures. Fix possible memory corruption when
Steve Frenchabb63d62007-10-18 02:58:40 +0000140EAGAIN returned on kern_recvmsg. Return better error if server
Shirish Pargaonkare01b6402007-10-30 04:45:14 +0000141requires packet signing but client has disabled it. When mounted
142with cifsacl mount option - mode bits are approximated based
Steve French1fb64bf2007-11-01 02:12:10 +0000143on the contents of the ACL of the file or directory. When cifs
144mount helper is missing convert make sure that UNC name
145has backslash (not forward slash) between ip address of server
146and the share name.
Steve French407f61a2007-09-28 06:53:39 +0000147
Steve Frenchb609f062007-07-09 07:55:14 +0000148Version 1.50
149------------
Steve French7521a3c2007-07-11 18:30:34 +0000150Fix NTLMv2 signing. NFS server mounted over cifs works (if cifs mount is
Steve French2d785a52007-07-15 01:48:57 +0000151done with "serverino" mount option). Add support for POSIX Unlink
152(helps with certain sharing violation cases when server such as
Steve Frencha403a0a2007-07-26 15:54:16 +0000153Samba supports newer POSIX CIFS Protocol Extensions). Add "nounix"
154mount option to allow disabling the CIFS Unix Extensions for just
155that mount. Fix hang on spinlock in find_writable_file (race when
Jeff Layton39db8102007-08-24 03:16:51 +0000156reopening file after session crash). Byte range unlock request to
157windows server could unlock more bytes (on server copy of file)
158than intended if start of unlock request is well before start of
159a previous byte range lock that we issued.
Steve Frenchb609f062007-07-09 07:55:14 +0000160
Steve French5858ae42007-04-25 11:59:10 +0000161Version 1.49
162------------
163IPv6 support. Enable ipv6 addresses to be passed on mount (put the ipv6
164address after the "ip=" mount option, at least until mount.cifs is fixed to
Steve French4523cc32007-04-30 20:13:06 +0000165handle DNS host to ipv6 name translation). Accept override of uid or gid
166on mount even when Unix Extensions are negotiated (it used to be ignored
167when Unix Extensions were ignored). This allows users to override the
168default uid and gid for files when they are certain that the uids or
Jeff Layton8426c392007-05-05 03:27:49 +0000169gids on the server do not match those of the client. Make "sec=none"
170mount override username (so that null user connection is attempted)
Steve French75865f82007-06-24 18:30:48 +0000171to match what documentation said. Support for very large reads, over 127K,
172available to some newer servers (such as Samba 3.0.26 and later but
173note that it also requires setting CIFSMaxBufSize at module install
174time to a larger value which may hurt performance in some cases).
Jeff38c10a12007-07-06 21:10:07 +0000175Make sign option force signing (or fail if server does not support it).
Steve French5858ae42007-04-25 11:59:10 +0000176
177Version 1.48
Steve French3677db12007-02-26 16:46:11 +0000178------------
179Fix mtime bouncing around from local idea of last write times to remote time.
180Fix hang (in i_size_read) when simultaneous size update of same remote file
Steve French8a236262007-03-06 00:31:00 +0000181on smp system corrupts sequence number. Do not reread unnecessarily partial page
182(which we are about to overwrite anyway) when writing out file opened rw.
Alan Tysonf5c1e2e2007-03-10 06:05:14 +0000183When DOS attribute of file on non-Unix server's file changes on the server side
184from read-only back to read-write, reflect this change in default file mode
Steve French066fcb02007-03-23 00:45:08 +0000185(we had been leaving a file's mode read-only until the inode were reloaded).
186Allow setting of attribute back to ATTR_NORMAL (removing readonly dos attribute
187when archive dos attribute not set and we are changing mode back to writeable
Steve French5268df22007-04-06 19:28:16 +0000188on server which does not support the Unix Extensions). Remove read only dos
189attribute on chmod when adding any write permission (ie on any of
190user/group/other (not all of user/group/other ie 0222) when
Steve French2dd29d32007-04-23 22:07:35 +0000191mounted to windows. Add support for POSIX MkDir (slight performance
192enhancement and eliminates the network race between the mkdir and set
193path info of the mode).

198Fix oops in list_del during mount caused by unaligned string.
Steve French595dcfe2007-02-08 18:11:42 +0000199Fix file corruption which could occur on some large file
200copies caused by writepages page i/o completion bug.
Steve Frencha8507902007-02-06 20:43:30 +0000201Seek to SEEK_END forces check for update of file size for non-cached
Steve French8af18972007-02-14 04:42:51 +0000202files. Allow file size to be updated on remote extend of locally open,
203non-cached file. Fix reconnect to newer Samba servers (or other servers
204which support the CIFS Unix/POSIX extensions) so that we again tell the
205server the Unix/POSIX cifs capabilities which we support (SetFSInfo).
206Add experimental support for new POSIX Open/Mkdir (which returns
207stat information on the open, and allows setting the mode).

211Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
Steve French4b952a92006-10-30 21:46:13 +0000212Allow null user to be specified on mount ("username="). Do not return
213EINVAL on readdir when filldir fails due to overwritten blocksize
Steve French8e87d4d2006-11-02 03:45:24 +0000214(fixes FC problem). Return error in rename 2nd attempt retry (ie report
215if rename by handle also fails, after rename by path fails, we were
Steve French33ec32f2006-12-08 04:14:28 +0000216not reporting whether the retry worked or not). Fix NTLMv2 to
217work to Windows servers (mount with option "sec=ntlmv2").

221Do not time out lockw calls when using posix extensions. Do not
222time out requests if server still responding reasonably fast
Steve Frenche466e482006-08-15 13:07:18 +0000223on requests on other threads. Improve POSIX locking emulation,
224(lock cancel now works, and unlock of merged range works even
225to Windows servers now). Fix oops on mount to lanman servers
Steve Frenchea4c07d2006-08-16 19:44:25 +0000226(win9x, os/2 etc.) when null password. Do not send listxattr
Steve French2fe87f02006-09-21 07:02:52 +0000227(SMB to query all EAs) if nouser_xattr specified. Fix SE Linux

Steve French39798772006-05-31 22:40:51 +0000230Version 1.44
231------------
232Rewritten sessionsetup support, including support for legacy SMB
233session setup needed for OS/2 and older servers such as Windows 95 and 98.
Steve French5bafd762006-06-07 00:18:43 +0000234Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
235so we can do search (ls etc.) to OS/2. Do not send NTCreateX
236or recent levels of FindFirst unless server says it supports NT SMBs
Steve French1717ffc2006-06-08 05:41:32 +0000237(instead use legacy equivalents from LANMAN dialect). Fix to allow

Steve Frencha878fb22006-05-30 18:04:19 +0000245(disabled by default controlled by proc/fs/cifs/Experimental).
246Handle conversion of long share names (especially Asian languages)
Steve French26a21b92006-05-31 18:05:34 +0000247to Unicode during mount. Fix memory leak in sess struct on reconnect.
248Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
249cifs open which helps rare case when setpathinfo fails or server does
250not support it.

256looping when signing required by server (2.6.16 kernel only). Fix readdir
257vs. rename race which could cause each to hang. Return . and .. even
258if server does not. Allow searches to skip first three entries and
259begin at any location. Fix oops in find_writeable_file.

262------------
263Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
264configure stronger authentication. Fix sfu symlinks so they can
Steve French184ed212006-02-24 06:15:11 +0000265be followed (not just recognized). Fix wraparound of bcc on
266read responses when buffer size over 64K and also fix wrap of
267max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in

270locking support (requires server with newest CIFS UNIX Extensions
Steve French083d3a22006-03-03 09:53:36 +0000271to the protocol implemented). Slow down negprot slightly in port 139
272RFC1001 case to give session_init time on buggy servers.

275------------
Steve French84afc292005-12-02 13:32:45 -0800276Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
Steve French0a4b92c2006-01-12 15:44:21 -0800277of readpages by eliminating one extra memcpy. Allow update of file size
278from remote server even if file is open for write as long as mount is
Steve Frencheeac8042006-01-13 21:34:58 -0800279directio. Recognize share mode security and send NTLM encrypted password
280on tree connect if share mode negotiated.

Steve French23e7dd72005-10-20 13:44:56 -0700282Version 1.39
283------------
Steve French3abb9272005-11-28 08:16:13 -0800284Defer close of a file handle slightly if pending writes depend on that handle
Steve French23e7dd72005-10-20 13:44:56 -0700285(this reduces the EBADF bad file handle errors that can be logged under heavy
Steve French3c50c612005-11-10 17:31:33 -0800286stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
Steve French3abb9272005-11-28 08:16:13 -0800287Fix SFU style symlinks and mknod needed for servers which do not support the
288CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
289dentries so files that the client sees as deleted but that later get created
Steve French6473a552005-11-29 20:20:10 -0800290on the server will be recognized. Add client side permission check on setattr.
Steve French83451872005-12-01 17:12:59 -0800291Timeout stuck requests better (where server has never responded or sent corrupt
292responses)
Steve French23e7dd72005-10-20 13:44:56 -0700293
Steve French190fdeb2005-10-10 11:48:26 -0700294Version 1.38
295------------
296Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
297to be smaller at first (but increasing) so large write performance performance
298over GigE is better. Do not hang thread on illegal byte range lock response
299from Windows (Windows can send an RFC1001 size which does not match smb size) by
300allowing an SMBs TCP length to be up to a few bytes longer than it should be.
301wsize and rsize can now be larger than negotiated buffer size if server
302supports large readx/writex, even when directio mount flag not specified.
303Write size will in many cases now be 16K instead of 4K which greatly helps
Steve French4ca9c192005-10-10 19:52:13 -0700304file copy performance on lightly loaded networks. Fix oops in dnotify
Steve French1047abc2005-10-11 19:58:06 -0700305when experimental config flag enabled. Make cifsFYI more granular.
Steve French190fdeb2005-10-10 11:48:26 -0700306
Steve Frencheafe8702005-09-15 21:47:30 -0700307Version 1.37
308------------
309Fix readdir caching when unlink removes file in current search buffer,
310and this is followed by a rewind search to just before the deleted entry.
Steve Frenche30dcf32005-09-20 20:49:16 -0700311Do not attempt to set ctime unless atime and/or mtime change requested
Steve French20962432005-09-21 22:05:57 -0700312(most servers throw it away anyway). Fix length check of received smbs
Steve French70ca7342005-09-22 16:32:06 -0700313to be more accurate. Fix big endian problem with mapchars mount option,
314and with a field returned by statfs.
Steve Frencheafe8702005-09-15 21:47:30 -0700315
Steve Frenchc46fa8a2005-08-18 20:49:57 -0700316Version 1.36
317------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700318Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
Steve French6b8edfe2005-08-23 20:26:03 -0700319For these older servers, add option for passing netbios name of server in
Steve French16abbec2005-08-30 13:10:14 -0700320on mount (servernetbiosname). Add suspend support for power management, to
321avoid cifsd thread preventing software suspend from working.
Steve Frenchc46fa8a2005-08-18 20:49:57 -0700322Add mount option for disabling the default behavior of sending byte range lock
323requests to the server (necessary for certain applications which break with
324mandatory lock behavior such as Evolution), and also mount option for
325requesting case insensitive matching for path based requests (requesting
326case sensitive is the default).
327
Steve Frenchf4cfd692005-07-14 18:29:02 -0500328Version 1.35
329------------
330Add writepage performance improvements. Fix path name conversions
331for long filenames on mounts which were done with "mapchars" mount option
Steve Frencha10faeb22005-08-22 21:38:31 -0700332specified. Ensure multiplex ids do not collide. Fix case in which
333rmmod can oops if done soon after last unmount. Fix truncated
334search (readdir) output when resume filename was a long filename.
335Fix filename conversion when mapchars mount option was specified and
336filename was a long filename.
Steve Frenchf4cfd692005-07-14 18:29:02 -0500337
Steve French11aa0142005-04-28 22:41:10 -0700338Version 1.34
339------------
340Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
Steve French31ca3bc2005-04-28 22:41:11 -0700341Do not oops if root user kills cifs oplock kernel thread or
342kills the cifsd thread (NB: killing the cifs kernel threads is not
343recommended, unmount and rmmod cifs will kill them when they are
Steve French68575472005-04-30 11:10:57 -0700344no longer needed). Fix readdir to ASCII servers (ie older servers
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700345which do not support Unicode) and also require asterisk.
Steve French3079ca62005-06-09 14:44:07 -0700346Fix out of memory case in which data could be written one page
347off in the page cache.
Steve French11aa0142005-04-28 22:41:10 -0700348
Steve French966ca922005-04-28 22:41:08 -0700349Version 1.33
350------------
351Fix caching problem, in which readdir of directory containing a file
352which was cached could cause the file's time stamp to be updated
353without invalidating the readahead data (so we could get stale
354file data on the client for that file even as the server copy changed).
Steve Frenchcd634992005-04-28 22:41:10 -0700355Cleanup response processing so cifsd can not loop when abnormally
356terminated.
Steve French966ca922005-04-28 22:41:08 -0700357
358
Steve Frenchf654bac2005-04-28 22:41:04 -0700359Version 1.32
Linus Torvalds1da177e2005-04-16 15:20:36 -0700360------------
361Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
362transact response for an SMB request and search entry split across two frames.
Steve Frenchf654bac2005-04-28 22:41:04 -0700363Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
364as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
365unless server explicitly claims to support them in CIFS Unix extensions
Steve Frenchad009ac2005-04-28 22:41:05 -0700366POSIX ACL capability bit. Fix packet signing when multiuser mounting with
Steve Frenchcbe04762005-04-28 22:41:05 -0700367different users from the same client to the same server. Fix oops in
Steve French6a0b4822005-04-28 22:41:05 -0700368cifs_close. Add mount option for remapping reserved characters in
369filenames (also allow recognizing files with created by SFU which have any
Steve French737b7582005-04-28 22:41:06 -0700370of these seven reserved characters, except backslash, to be recognized).
Steve French848f3fc2005-04-28 22:41:07 -0700371Fix invalid transact2 message (we were sometimes trying to interpret
Steve French099a58f2005-04-28 22:41:07 -0700372oplock breaks as SMB responses). Add ioctl for checking that the
373current uid matches the uid of the mounter (needed by umount.cifs).
374Reduce the number of large buffer allocations in cifs response processing
375(significantly reduces memory pressure under heavy stress with multiple
376processes accessing the same server at the same time).
Steve Frenchf654bac2005-04-28 22:41:04 -0700377
378Version 1.31
379------------
Linus Torvalds1da177e2005-04-16 15:20:36 -0700380Fix updates of DOS attributes and time fields so that files on NT4 servers
381do not get marked delete on close. Display sizes of cifs buffer pools in
382cifs stats. Fix oops in unmount when cifsd thread being killed by
383shutdown. Add generic readv/writev and aio support. Report inode numbers
384consistently in readdir and lookup (when serverino mount option is
385specified use the inode number that the server reports - for both lookup
386and readdir, otherwise by default the locally generated inode number is used
387for inodes created in either path since servers are not always able to
388provide unique inode numbers when exporting multiple volumes from under one
389sharename).
390
391Version 1.30
392------------
393Allow new nouser_xattr mount parm to disable xattr support for user namespace.
394Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
395(mostly affects NT4 servers) by retry with handle based network operation.
396Add new POSIX Query FS Info for returning statfs info more accurately.
397Handle passwords with multiple commas in them.
398
399Version 1.29
400------------
401Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
402Fix capabilities flags for large readx so as to allow reads larger than 64K.
403
404Version 1.28
405------------
406Add module init parm for large SMB buffer size (to allow it to be changed
407from its default of 16K) which is especially useful for large file copy
408when mounting with the directio mount option. Fix oops after
409returning from mount when experimental ExtendedSecurity enabled and
410SpnegoNegotiated returning invalid error. Fix case to retry better when
411peek returns from 1 to 3 bytes on socket which should have more data.
412Fixed path based calls (such as cifs lookup) to handle path names
413longer than 530 (now can handle PATH_MAX). Fix pass through authentication
414from Samba server to DC (Samba required dummy LM password).
415
416Version 1.27
417------------
418Turn off DNOTIFY (directory change notification support) by default
419(unless built with the experimental flag) to fix hang with KDE
420file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
421waiting on an SMB response) in SendReceive when session dies but
422reconnects quickly from another task. Add module init parms for
423minimum number of large and small network buffers in the buffer pools,
424and for the maximum number of simultaneous requests.
425
426Version 1.26
427------------
428Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
429and other POSIX CIFS compliant servers. Fix error mapping for getfacl
430to EOPNOTSUPP when server does not support posix acls on the wire. Fix
431improperly zeroed buffer in CIFS Unix extensions set times call.
432
433Version 1.25
434------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700435Fix internationalization problem in cifs readdir with filenames that map to
Alexey Dobriyan4de151d2006-03-22 00:13:35 +0100436longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
Linus Torvalds1da177e2005-04-16 15:20:36 -0700437for readdir to netapp servers. Fix search rewind (seek into readdir to return
438non-consecutive entries). Do not do readdir when server negotiates
439buffer size to small to fit filename. Add support for reading POSIX ACLs from
440the server (add also acl and noacl mount options).
441
442Version 1.24
443------------
444Optionally allow using server side inode numbers, rather than client generated
445ones by specifying mount option "serverino" - this is required for some apps
446to work which double check hardlinked files and have persistent inode numbers.
447
448Version 1.23
449------------
450Multiple bigendian fixes. On little endian systems (for reconnect after
451network failure) fix tcp session reconnect code so we do not try first
452to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
453as directories rather than symlinks because we can do follow link on them.
454
455Version 1.22
456------------
457Add config option to enable XATTR (extended attribute) support, mapping
458xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
459minor fixes pointed out by the Stanford SWAT checker (mostly missing
460or out of order NULL pointer checks in little used error paths).
461
462Version 1.21
463------------
464Add new mount parm to control whether mode check (generic_permission) is done
465on the client. If Unix extensions are enabled and the uids on the client
466and server do not match, client permission checks are meaningless on
467server uids that do not exist on the client (this does not affect the
468normal ACL check which occurs on the server). Fix default uid
469on mknod to match create and mkdir. Add optional mount parm to allow
470override of the default uid behavior (in which the server sets the uid
471and gid of newly created files). Normally for network filesystem mounts
472user want the server to set the uid/gid on newly created files (rather than
473using uid of the client processes you would in a local filesystem).
474
475Version 1.20
476------------
477Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
478info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
479(in build_wildcard_path_from_dentry). Fix mknod to pass type field
480(block/char/fifo) properly. Remove spurious mount warning log entry when
481credentials passed as mount argument. Set major/minor device number in
482inode for block and char devices when unix extensions enabled.
483
484Version 1.19
485------------
486Fix /proc/fs/cifs/Stats and DebugData display to handle larger
487amounts of return data. Properly limit requests to MAX_REQ (50
488is the usual maximum active multiplex SMB/CIFS requests per server).
489Do not kill cifsd (and thus hurt the other SMB session) when more than one
490session to the same server (but with different userids) exists and one
491of the two user's smb sessions is being removed while leaving the other.
492Do not loop reconnecting in cifsd demultiplex thread when admin
493kills the thread without going through unmount.
494
495Version 1.18
496------------
497Do not rename hardlinked files (since that should be a noop). Flush
498cached write behind data when reopening a file after session abend,
499except when already in write. Grab per socket sem during reconnect
500to avoid oops in sendmsg if overlapping with reconnect. Do not
501reset cached inode file size on readdir for files open for write on
502client.
503
504
505Version 1.17
506------------
507Update number of blocks in file so du command is happier (in Linux a fake
508blocksize of 512 is required for calculating number of blocks in inode).
509Fix prepare write of partial pages to read in data from server if possible.
510Fix race on tcpStatus field between unmount and reconnection code, causing
511cifsd process sometimes to hang around forever. Improve out of memory
512checks in cifs_filldir
513
514Version 1.16
515------------
516Fix incorrect file size in file handle based setattr on big endian hardware.
517Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
518and closing file structs in writepage/partialpagewrite. Add statistics
519for each mounted share (new menuconfig option). Fix endianness problem in
520volume information displayed in /proc/fs/cifs/DebugData (only affects
521affects big endian architectures). Prevent renames while constructing
522path names for open, mkdir and rmdir.
523
524Version 1.15
525------------
526Change to mempools for alloc smb request buffers and multiplex structs
527to better handle low memory problems (and potential deadlocks).
528
529Version 1.14
530------------
531Fix incomplete listings of large directories on Samba servers when Unix
532extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
533rename deadlock when writing out dirty pages at same time.
534
535Version 1.13
536------------
537Fix open of files in which O_CREATE can cause the mode to change in
538some cases. Fix case in which retry of write overlaps file close.
539Fix PPC64 build error. Reduce excessive stack usage in smb password
540hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
541
542Version 1.12
543------------
544Fixes for large file copy, signal handling, socket retry, buffer
545allocation and low memory situations.
546
547Version 1.11
548------------
549Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
550also now allowing support for specifying client netbiosname. NT4 support added.
551
552Version 1.10
553------------
554Fix reconnection (and certain failed mounts) to properly wake up the
555blocked users thread so it does not seem hung (in some cases was blocked
556until the cifs receive timeout expired). Fix spurious error logging
557to kernel log when application with open network files killed.
558
559Version 1.09
560------------
561Fix /proc/fs module unload warning message (that could be logged
562to the kernel log). Fix intermittent failure in connectathon
563test7 (hardlink count not immediately refreshed in case in which
564inode metadata can be incorrectly kept cached when time near zero)
565
566Version 1.08
567------------
568Allow file_mode and dir_mode (specified at mount time) to be enforced
569locally (the server already enforced its own ACLs too) for servers
570that do not report the correct mode (do not support the
571CIFS Unix Extensions).
572
573Version 1.07
574------------
575Fix some small memory leaks in some unmount error paths. Fix major leak
576of cache pages in readpages causing multiple read oriented stress
577testcases (including fsx, and even large file copy) to fail over time.
578
579Version 1.06
580------------
581Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
582This allows files that differ only in case and improves performance of file
583creation and file open to such servers. Fix semaphore conflict which causes
584slow delete of open file to Samba (which unfortunately can cause an oplock
585break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
586
587Version 1.05
588------------
589fixes to cifs_readpages for fsx test case
590
591Version 1.04
592------------
593Fix caching data integrity bug when extending file size especially when no
594oplock on file. Fix spurious logging of valid already parsed mount options
595that are parsed outside of the cifs vfs such as nosuid.
596
597
598Version 1.03
599------------
600Connect to server when port number override not specified, and tcp port
601unitialized. Reset search to restart at correct file when kernel routine
602filldir returns error during large directory searches (readdir).
603
604Version 1.02
605------------
606Fix caching problem when files opened by multiple clients in which
607page cache could contain stale data, and write through did
608not occur often enough while file was still open when read ahead
609(read oplock) not allowed. Treat "sep=" when first mount option
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700610as an override of comma as the default separator between mount
Linus Torvalds1da177e2005-04-16 15:20:36 -0700611options.
612
613Version 1.01
614------------
615Allow passwords longer than 16 bytes. Allow null password string.
616
617Version 1.00
618------------
619Gracefully clean up failed mounts when attempting to mount to servers such as
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700620Windows 98 that terminate tcp sessions during protocol negotiation. Handle
Linus Torvalds1da177e2005-04-16 15:20:36 -0700621embedded commas in mount parsing of passwords.
622
623Version 0.99
624------------
625Invalidate local inode cached pages on oplock break and when last file
626instance is closed so that the client does not continue using stale local
627copy rather than later modified server copy of file. Do not reconnect
628when server drops the tcp session prematurely before negotiate
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700629protocol response. Fix oops in reopen_file when dentry freed. Allow
Linus Torvalds1da177e2005-04-16 15:20:36 -0700630the support for CIFS Unix Extensions to be disabled via proc interface.
631
632Version 0.98
633------------
634Fix hang in commit_write during reconnection of open files under heavy load.
635Fix unload_nls oops in a mount failure path. Serialize writes to same socket
636which also fixes any possible races when cifs signatures are enabled in SMBs
637being sent out of signature sequence number order.
638
639Version 0.97
640------------
641Fix byte range locking bug (endian problem) causing bad offset and
642length.
643
644Version 0.96
645------------
646Fix oops (in send_sig) caused by CIFS unmount code trying to
647wake up the demultiplex thread after it had exited. Do not log
648error on harmless oplock release of closed handle.
649
650Version 0.95
651------------
652Fix unsafe global variable usage and password hash failure on gcc 3.3.1
653Fix problem reconnecting secondary mounts to same server after session
654failure. Fix invalid dentry - race in mkdir when directory gets created
655by another client between the lookup and mkdir.
656
657Version 0.94
658------------
659Fix to list processing in reopen_files. Fix reconnection when server hung
660but tcpip session still alive. Set proper timeout on socket read.
661
662Version 0.93
663------------
664Add missing mount options including iocharset. SMP fixes in write and open.
665Fix errors in reconnecting after TCP session failure. Fix module unloading
666of default nls codepage
667

718Version 0.83
719------------
720Fix oops when mounting to long server names caused by inverted parms to kmalloc.
721Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
722we will choose a cifs user session (smb uid) that better matches the local

804
805Version 0.69
806------------
807Fix buffer overrun in readdir which caused intermittent kernel oopses.
808Fix writepage code to release kmap on write data. Allow "-ip=" new
809mount option to be passed in on parameter distinct from the first part
810(server name portion of) the UNC name. Allow override of the
811tcp port of the target server via new mount option "-port="
812
813Version 0.68

816reflected in the local inode immediately. Cleanup of whitespace
817to make 2.4 and 2.5 versions more consistent.
818
819
820Version 0.67
821------------
822Fix signal sending so that captive thread (cifsd) exits on umount
823(which was causing the warning in kmem_cache_free of the request buffers
824at rmmod time). This had broken as a sideeffect of the recent global
825kernel change to daemonize. Fix memory leak in readdir code which
826showed up in "ls -R" (and applications that did search rewinding).
827
828Version 0.66
829------------
830Reconnect tids and fids after session reconnection (still do not
831reconnect byte range locks though). Fix problem caching

854------------
855Fix temporary socket leak when bad userid or password specified
856(or other SMBSessSetup failure). Increase maximum buffer size to slightly

858sizes. Add support for readpages
859
860Version 0.61
861------------
862Fix oops when username not passed in on mount. Extensive fixes and improvements
863to error logging (strip redundant newlines, change debug macros to ensure newline
864passed in and to be more consistent). Fix writepage wrong file handle problem,
865a readonly file handle could be incorrectly used to attempt to write out
866file updates through the page cache to multiply open files. This could cause
867the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
868shares to the same Windows server when using different usernames
869(doing this to Samba servers worked but Windows was rejecting it) - now it is
870possible to use different userids when connecting to the same server from a
871Linux client. Fix oops when treeDisconnect called during unmount on
872previously freed socket.
873
874Version 0.60

888
889Version 0.57
890------------

1017------------
10181) Fixed lockrange to be correct (it was one byte too short)
1019
10202) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
1021show range as locked when there is a conflict with an existing lock.
1022
10233) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories

1025
10263) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
1027but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
1028session)
1029
10304) Fixed error logging of valid mount options
1031
10325) Removed logging of password field.
1033
10346) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
1035and cleaned them up and made them more consistent with other cifs functions.
