2------------
Steve French96c03bc2010-02-23 20:51:43 +00003Add sockopt=TCP_NODELAY mount option. EA (xattr) routines hardened
4to more strictly handle corrupt frames.

Steve French2f81e752009-11-25 00:11:31 +00006Version 1.61
7------------
8Fix append problem to Samba servers (files opened with O_APPEND could
9have duplicated data). Fix oops in cifs_lookup. Workaround problem
10mounting to OS/400 Netserve. Fix oops in cifs_get_tcp_session.
11Disable use of server inode numbers when server only
12partially supports them (e.g. for one server querying inode numbers on
Steve Frencha994b8f2009-12-07 05:44:46 +000013FindFirst fails but QPathInfo queries works). Fix oops with dfs in
14cifs_put_smb_ses. Fix mmap to work on directio mounts (needed
15for OpenOffice when on forcedirectio mount e.g.)

Steve French5bd90522009-07-30 02:26:14 +000017Version 1.60
18-------------
19Fix memory leak in reconnect. Fix oops in DFS mount error path.
20Set s_maxbytes to smaller (the max that vfs can handle) so that
Steve Frenchd0985642009-08-04 03:53:28 +000021sendfile will now work over cifs mounts again. Add noforcegid
Steve Frenchca43e3b2009-09-01 17:20:50 +000022and noforceuid mount parameters. Fix small mem leak when using
23ntlmv2. Fix 2nd mount to same server but with different port to
24be allowed (rather than reusing the 1st port) - only when the
25user explicitly overrides the port on the 2nd mount.

Steve Frenchc5077ec2009-05-28 15:09:04 +000027Version 1.59
28------------
29Client uses server inode numbers (which are persistent) rather than
30client generated ones by default (mount option "serverino" turned
Steve Frenchf0472d02009-06-06 21:09:39 +000031on by default if server supports it). Add forceuid and forcegid
32mount options (so that when negotiating unix extensions specifying
33which uid mounted does not immediately force the server's reported
Steve Frenchb77863b2009-07-09 22:51:38 +000034uids to be overridden). Add support for scope mount parm. Improve
35hard link detection to use same inode for both. Do not set
36read-only dos attribute on directories (for chmod) since Windows
37explorer special cases this attribute bit for directories for
38a different purpose.
Steve Frenchc5077ec2009-05-28 15:09:04 +000039
Steve Frenchff694522009-04-20 19:45:13 +000040Version 1.58
41------------
42Guard against buffer overruns in various UCS-2 to UTF-8 string conversions
43when the UTF-8 string is composed of unusually long (more than 4 byte) converted
Steve Frenchd185cda2009-04-30 17:45:10 +000044characters. Add support for mounting root of a share which redirects immediately
45to DFS target. Convert string conversion functions from Unicode to more
46accurately mark string length before allocating memory (which may help the
47rare cases where a UTF-8 string is much larger than the UCS2 string that
Steve Frenche836f012009-05-01 16:20:35 +000048we converted from). Fix endianness of the vcnum field used during
49session setup to distinguish multiple mounts to same server from different
Steve French0b3cc852009-05-04 08:37:12 +000050userids. Raw NTLMSSP fixed (it requires /proc/fs/cifs/experimental
51flag to be set to 2, and mount must enable krb5 to turn on extended security).
Steve Frenchc5077ec2009-05-28 15:09:04 +000052Performance of file create to Samba improved (posix create on lookup
53removes 1 of 2 network requests sent on file create)
Steve Frenchff694522009-04-20 19:45:13 +000054
Steve Frencheca6acf2009-02-20 05:43:09 +000055Version 1.57
56------------
57Improve support for multiple security contexts to the same server. We
58used to use the same "vcnumber" for all connections which could cause
59the server to treat subsequent connections, especially those that
60are authenticated as guest, as reconnections, invalidating the earlier
61user's smb session. This fix allows cifs to mount multiple times to the
62same server with different userids without risking invalidating earlier
Steve Frenchb298f222009-02-21 21:17:43 +000063established security contexts. fsync now sends SMB Flush operation
64to better ensure that we wait for server to write all of the data to
Steve Frenchbe652442009-02-23 15:21:59 +000065server disk (not just write it over the network). Add new mount
66parameter to allow user to disable sending the (slow) SMB flush on
67fsync if desired (fsync still flushes all cached write data to the server).
Steve French64cc2c62009-03-04 19:54:08 +000068Posix file open support added (turned off after one attempt if server
69fails to support it properly, as with Samba server versions prior to 3.3.2)
Steve Frenchb363b332009-03-18 05:57:22 +000070Fix "redzone overwritten" bug in cifs_put_tcon (CIFSTcon may allocate too
71little memory for the "nativeFileSystem" field returned by the server
Steve French85a6dac2009-04-01 05:22:00 +000072during mount). Endian convert inode numbers if necessary (makes it easier
73to compare inode numbers on network files from big endian systems).
Steve Frencheca6acf2009-02-20 05:43:09 +000074
Steve French13a6e422008-12-02 17:24:33 +000075Version 1.56
76------------
77Add "forcemandatorylock" mount option to allow user to use mandatory
78rather than posix (advisory) byte range locks, even though server would
Steve French8be0ed42008-12-05 19:14:12 +000079support posix byte range locks. Fix query of root inode when prefixpath
80specified and user does not have access to query information about the
Steve Frenchc6fbba02008-12-18 01:41:20 +000081top of the share. Fix problem in 2.6.28 resolving DFS paths to
Steve French42c24542009-01-13 22:03:55 +000082Samba servers (worked to Windows). Fix rmdir so that pending search
83(readdir) requests do not get invalid results which include the now
Steve French69765522009-02-17 01:29:40 +000084removed directory. Fix oops in cifs_dfs_ref.c when prefixpath is not reachable
Steve Frenchc3b2a0c2009-02-20 04:32:45 +000085when using DFS. Add better file create support to servers which support
86the CIFS POSIX protocol extensions (this adds support for new flags
87on create, and improves semantics for write of locked ranges).
Steve French13a6e422008-12-02 17:24:33 +000088
Steve French32709582008-10-20 00:44:19 +000089Version 1.55
90------------
91Various fixes to make delete of open files behavior more predictable
92(when delete of an open file fails we mark the file as "delete-on-close"
93in a way that more servers accept, but only if we can first rename the
Steve French84210e92008-10-23 04:42:37 +000094file to a temporary name). Add experimental support for more safely
Steve Frenchedf1ae42008-10-29 00:47:57 +000095handling fcntl(F_SETLEASE). Convert cifs to using blocking tcp
96sends, and also let tcp autotune the socket send and receive buffers.
97This reduces the number of EAGAIN errors returned by TCP/IP in
98high stress workloads (and the number of retries on socket writes
Steve Frenchbfb59822008-11-18 16:33:48 +000099when sending large SMBWriteX requests). Fix case in which a portion of
100data can in some cases not get written to the file on the server before the
101file is closed. Fix DFS parsing to properly handle path consumed field,
102and to handle certain codepage conversions better. Fix mount and
103umount race that can cause oops in mount or umount or reconnect.
Steve French32709582008-10-20 00:44:19 +0000104
Steve French26b994f2008-08-06 05:11:33 +0000105Version 1.54
106------------
107Fix premature write failure on congested networks (we would give up
108on EAGAIN from the socket too quickly on large writes).
109Cifs_mkdir and cifs_create now respect the setgid bit on parent dir.
110Fix endian problems in acl (mode from/to cifs acl) on bigendian
Steve French6ce5eec2008-08-26 00:37:14 +0000111architectures. Fix problems with preserving timestamps on copying open
112files (e.g. "cp -a") to Windows servers. For mkdir and create honor setgid bit
113on parent directory when server supports Unix Extensions but not POSIX
114create. Update cifs.upcall version to handle new Kerberos sec flags
Jeff Layton87ed1d62008-08-27 17:53:30 +0000115(this requires update of cifs.upcall program from Samba). Fix memory leak
Steve French2e655022008-08-28 15:30:06 +0000116on dns_upcall (resolving DFS referralls). Fix plain text password
117authentication (requires setting SecurityFlags to 0x30030 to enable
118lanman and plain text though). Fix writes to be at correct offset when
119file is open with O_APPEND and file is on a directio (forcediretio) mount.
Steve French32709582008-10-20 00:44:19 +0000120Fix bug in rewinding readdir directory searches. Add nodfs mount option.
Steve French26b994f2008-08-06 05:11:33 +0000121
Steve French39da9842008-04-28 04:04:34 +0000122Version 1.53
123------------
Steve French0e4bbde2008-05-20 19:50:46 +0000124DFS support added (Microsoft Distributed File System client support needed
125for referrals which enable a hierarchical name space among servers).
Steve Frenchdbdbb872008-06-10 21:21:56 +0000126Disable temporary caching of mode bits to servers which do not support
127storing of mode (e.g. Windows servers, when client mounts without cifsacl
128mount option) and add new "dynperm" mount option to enable temporary caching
129of mode (enable old behavior). Fix hang on mount caused when server crashes
130tcp session during negotiate protocol.
Steve French39da9842008-04-28 04:04:34 +0000131
Steve Frenchce06c9f2007-11-08 21:12:01 +0000132Version 1.52
133------------
Jeff Layton9b8f5f52007-11-09 23:25:04 +0000134Fix oops on second mount to server when null auth is used.
Jeff Laytoncea21802007-11-20 23:19:03 +0000135Enable experimental Kerberos support. Return writebehind errors on flush
136and sync so that events like out of disk space get reported properly on
Jeff Layton1d9a8852007-12-31 01:37:11 +0000137cached files. Fix setxattr failure to certain Samba versions. Fix mount
138of second share to disconnected server session (autoreconnect on this).
Steve French97837582007-12-31 07:47:21 +0000139Add ability to modify cifs acls for handling chmod (when mounted with
Steve French03a143c2008-02-14 06:38:30 +0000140cifsacl flag). Fix prefixpath path separator so we can handle mounts
141with prefixpaths longer than one directory (one path component) when
Steve French932e2d22008-04-04 21:59:35 +0000142mounted to Windows servers. Fix slow file open when cifsacl
Jeff Layton63534502008-05-12 19:56:05 -0700143enabled. Fix memory leak in FindNext when the SMB call returns -EBADF.

Steve French407f61a2007-09-28 06:53:39 +0000146Version 1.51
147------------
148Fix memory leak in statfs when mounted to very old servers (e.g.
Steve French92ad9b92007-09-29 05:21:58 +0000149Windows 9x). Add new feature "POSIX open" which allows servers
150which support the current POSIX Extensions to provide better semantics
151(e.g. delete for open files opened with posix open). Take into
152account umask on posix mkdir not just older style mkdir. Add
153ability to mount to IPC$ share (which allows CIFS named pipes to be
Steve French297647c2007-10-12 04:11:59 +0000154opened, read and written as if they were files). When 1st tree
155connect fails (e.g. due to signing negotiation failure) fix
156leak that causes cifsd not to stop and rmmod to fail to cleanup
Cyril Gorcunov8f2376a2007-10-14 17:58:43 +0000157cifs_request_buffers pool. Fix problem with POSIX Open/Mkdir on
Steve Frenchc18c7322007-10-17 18:01:11 +0000158bigendian architectures. Fix possible memory corruption when
Steve Frenchabb63d62007-10-18 02:58:40 +0000159EAGAIN returned on kern_recvmsg. Return better error if server
Shirish Pargaonkare01b6402007-10-30 04:45:14 +0000160requires packet signing but client has disabled it. When mounted
161with cifsacl mount option - mode bits are approximated based
Steve French1fb64bf2007-11-01 02:12:10 +0000162on the contents of the ACL of the file or directory. When cifs
163mount helper is missing convert make sure that UNC name
164has backslash (not forward slash) between ip address of server
165and the share name.

Steve Frenchb609f062007-07-09 07:55:14 +0000167Version 1.50
168------------
Steve French7521a3c2007-07-11 18:30:34 +0000169Fix NTLMv2 signing. NFS server mounted over cifs works (if cifs mount is
Steve French2d785a52007-07-15 01:48:57 +0000170done with "serverino" mount option). Add support for POSIX Unlink
171(helps with certain sharing violation cases when server such as
Steve Frencha403a0a2007-07-26 15:54:16 +0000172Samba supports newer POSIX CIFS Protocol Extensions). Add "nounix"
173mount option to allow disabling the CIFS Unix Extensions for just
174that mount. Fix hang on spinlock in find_writable_file (race when
Jeff Layton39db8102007-08-24 03:16:51 +0000175reopening file after session crash). Byte range unlock request to
176windows server could unlock more bytes (on server copy of file)
177than intended if start of unlock request is well before start of
178a previous byte range lock that we issued.
Steve Frenchb609f062007-07-09 07:55:14 +0000179
Steve French5858ae42007-04-25 11:59:10 +0000180Version 1.49
181------------
182IPv6 support. Enable ipv6 addresses to be passed on mount (put the ipv6
183address after the "ip=" mount option, at least until mount.cifs is fixed to
Steve French4523cc32007-04-30 20:13:06 +0000184handle DNS host to ipv6 name translation). Accept override of uid or gid
185on mount even when Unix Extensions are negotiated (it used to be ignored
186when Unix Extensions were ignored). This allows users to override the
187default uid and gid for files when they are certain that the uids or
Jeff Layton8426c392007-05-05 03:27:49 +0000188gids on the server do not match those of the client. Make "sec=none"
189mount override username (so that null user connection is attempted)
Steve French75865f82007-06-24 18:30:48 +0000190to match what documentation said. Support for very large reads, over 127K,
191available to some newer servers (such as Samba 3.0.26 and later but
192note that it also requires setting CIFSMaxBufSize at module install
193time to a larger value which may hurt performance in some cases).
Jeff38c10a12007-07-06 21:10:07 +0000194Make sign option force signing (or fail if server does not support it).
Steve French5858ae42007-04-25 11:59:10 +0000195
196Version 1.48
Steve French3677db12007-02-26 16:46:11 +0000197------------
198Fix mtime bouncing around from local idea of last write times to remote time.
199Fix hang (in i_size_read) when simultaneous size update of same remote file
Steve French8a236262007-03-06 00:31:00 +0000200on smp system corrupts sequence number. Do not reread unnecessarily partial page
201(which we are about to overwrite anyway) when writing out file opened rw.
Alan Tysonf5c1e2e2007-03-10 06:05:14 +0000202When DOS attribute of file on non-Unix server's file changes on the server side
203from read-only back to read-write, reflect this change in default file mode
Steve French066fcb02007-03-23 00:45:08 +0000204(we had been leaving a file's mode read-only until the inode were reloaded).
205Allow setting of attribute back to ATTR_NORMAL (removing readonly dos attribute
206when archive dos attribute not set and we are changing mode back to writeable
Steve French5268df22007-04-06 19:28:16 +0000207on server which does not support the Unix Extensions). Remove read only dos
208attribute on chmod when adding any write permission (ie on any of
209user/group/other (not all of user/group/other ie 0222) when
Steve French2dd29d32007-04-23 22:07:35 +0000210mounted to windows. Add support for POSIX MkDir (slight performance
211enhancement and eliminates the network race between the mkdir and set
212path info of the mode).

Steve French8af18972007-02-14 04:42:51 +0000221files. Allow file size to be updated on remote extend of locally open,
222non-cached file. Fix reconnect to newer Samba servers (or other servers
223which support the CIFS Unix/POSIX extensions) so that we again tell the
224server the Unix/POSIX cifs capabilities which we support (SetFSInfo).
225Add experimental support for new POSIX Open/Mkdir (which returns
226stat information on the open, and allows setting the mode).

241time out requests if server still responding reasonably fast
Steve Frenche466e482006-08-15 13:07:18 +0000242on requests on other threads. Improve POSIX locking emulation,
243(lock cancel now works, and unlock of merged range works even
244to Windows servers now). Fix oops on mount to lanman servers
Steve Frenchea4c07d2006-08-16 19:44:25 +0000245(win9x, os/2 etc.) when null password. Do not send listxattr

251Rewritten sessionsetup support, including support for legacy SMB
252session setup needed for OS/2 and older servers such as Windows 95 and 98.
Steve French5bafd762006-06-07 00:18:43 +0000253Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
254so we can do search (ls etc.) to OS/2. Do not send NTCreateX
255or recent levels of FindFirst unless server says it supports NT SMBs
Steve French1717ffc2006-06-08 05:41:32 +0000256(instead use legacy equivalents from LANMAN dialect). Fix to allow

Steve Frencha878fb22006-05-30 18:04:19 +0000264(disabled by default controlled by proc/fs/cifs/Experimental).
265Handle conversion of long share names (especially Asian languages)
Steve French26a21b92006-05-31 18:05:34 +0000266to Unicode during mount. Fix memory leak in sess struct on reconnect.

Steve French13298de2006-03-03 10:45:19 +0000271Version 1.42
272------------
273Fix slow oplock break when mounted to different servers at the same time and
Steve French60808232006-04-22 15:53:05 +0000274the tids match and we try to find matching fid on wrong server. Fix read
275looping when signing required by server (2.6.16 kernel only). Fix readdir
276vs. rename race which could cause each to hang. Return . and .. even
277if server does not. Allow searches to skip first three entries and
278begin at any location. Fix oops in find_writeable_file.
Steve French13298de2006-03-03 10:45:19 +0000279
Steve French12b3b8f2006-02-09 21:12:47 +0000280Version 1.41
281------------
282Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
283configure stronger authentication. Fix sfu symlinks so they can
Steve French184ed212006-02-24 06:15:11 +0000284be followed (not just recognized). Fix wraparound of bcc on
285read responses when buffer size over 64K and also fix wrap of
286max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
287cifs_user_read and cifs_readpages (when EAGAIN on send of smb
Steve French08547b02006-02-28 22:39:25 +0000288on socket is returned over and over). Add POSIX (advisory) byte range
289locking support (requires server with newest CIFS UNIX Extensions
Steve French083d3a22006-03-03 09:53:36 +0000290to the protocol implemented). Slow down negprot slightly in port 139
291RFC1001 case to give session_init time on buggy servers.
Steve French12b3b8f2006-02-09 21:12:47 +0000292
Steve French83451872005-12-01 17:12:59 -0800293Version 1.40
294------------
Steve French84afc292005-12-02 13:32:45 -0800295Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
Steve French0a4b92c2006-01-12 15:44:21 -0800296of readpages by eliminating one extra memcpy. Allow update of file size
297from remote server even if file is open for write as long as mount is
Steve Frencheeac8042006-01-13 21:34:58 -0800298directio. Recognize share mode security and send NTLM encrypted password
299on tree connect if share mode negotiated.
Steve French83451872005-12-01 17:12:59 -0800300
Steve French23e7dd72005-10-20 13:44:56 -0700301Version 1.39
302------------
Steve French3abb9272005-11-28 08:16:13 -0800303Defer close of a file handle slightly if pending writes depend on that handle
Steve French23e7dd72005-10-20 13:44:56 -0700304(this reduces the EBADF bad file handle errors that can be logged under heavy
Steve French3c50c612005-11-10 17:31:33 -0800305stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
Steve French3abb9272005-11-28 08:16:13 -0800306Fix SFU style symlinks and mknod needed for servers which do not support the
307CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
308dentries so files that the client sees as deleted but that later get created
Steve French6473a552005-11-29 20:20:10 -0800309on the server will be recognized. Add client side permission check on setattr.
Steve French83451872005-12-01 17:12:59 -0800310Timeout stuck requests better (where server has never responded or sent corrupt
311responses)
Steve French23e7dd72005-10-20 13:44:56 -0700312
Steve French190fdeb2005-10-10 11:48:26 -0700313Version 1.38
314------------
315Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
316to be smaller at first (but increasing) so large write performance performance
317over GigE is better. Do not hang thread on illegal byte range lock response
318from Windows (Windows can send an RFC1001 size which does not match smb size) by
319allowing an SMBs TCP length to be up to a few bytes longer than it should be.
320wsize and rsize can now be larger than negotiated buffer size if server
321supports large readx/writex, even when directio mount flag not specified.
322Write size will in many cases now be 16K instead of 4K which greatly helps
Steve French4ca9c192005-10-10 19:52:13 -0700323file copy performance on lightly loaded networks. Fix oops in dnotify
Steve French1047abc2005-10-11 19:58:06 -0700324when experimental config flag enabled. Make cifsFYI more granular.
Steve French190fdeb2005-10-10 11:48:26 -0700325
Steve Frencheafe8702005-09-15 21:47:30 -0700326Version 1.37
327------------
328Fix readdir caching when unlink removes file in current search buffer,
329and this is followed by a rewind search to just before the deleted entry.
Steve Frenche30dcf32005-09-20 20:49:16 -0700330Do not attempt to set ctime unless atime and/or mtime change requested
Steve French20962432005-09-21 22:05:57 -0700331(most servers throw it away anyway). Fix length check of received smbs
Steve French70ca7342005-09-22 16:32:06 -0700332to be more accurate. Fix big endian problem with mapchars mount option,
333and with a field returned by statfs.
Steve Frencheafe8702005-09-15 21:47:30 -0700334
Steve Frenchc46fa8a2005-08-18 20:49:57 -0700335Version 1.36
336------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700337Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
Steve French6b8edfe2005-08-23 20:26:03 -0700338For these older servers, add option for passing netbios name of server in
Steve French16abbec2005-08-30 13:10:14 -0700339on mount (servernetbiosname). Add suspend support for power management, to
340avoid cifsd thread preventing software suspend from working.
Steve Frenchc46fa8a2005-08-18 20:49:57 -0700341Add mount option for disabling the default behavior of sending byte range lock
342requests to the server (necessary for certain applications which break with
343mandatory lock behavior such as Evolution), and also mount option for
344requesting case insensitive matching for path based requests (requesting
345case sensitive is the default).
346
Steve Frenchf4cfd692005-07-14 18:29:02 -0500347Version 1.35
348------------
349Add writepage performance improvements. Fix path name conversions
350for long filenames on mounts which were done with "mapchars" mount option
Steve Frencha10faeb22005-08-22 21:38:31 -0700351specified. Ensure multiplex ids do not collide. Fix case in which
352rmmod can oops if done soon after last unmount. Fix truncated
353search (readdir) output when resume filename was a long filename.
354Fix filename conversion when mapchars mount option was specified and
355filename was a long filename.
Steve Frenchf4cfd692005-07-14 18:29:02 -0500356
Steve French11aa0142005-04-28 22:41:10 -0700357Version 1.34
358------------
359Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
Steve French31ca3bc2005-04-28 22:41:11 -0700360Do not oops if root user kills cifs oplock kernel thread or
361kills the cifsd thread (NB: killing the cifs kernel threads is not
362recommended, unmount and rmmod cifs will kill them when they are
Steve French68575472005-04-30 11:10:57 -0700363no longer needed). Fix readdir to ASCII servers (ie older servers
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700364which do not support Unicode) and also require asterisk.
Steve French3079ca62005-06-09 14:44:07 -0700365Fix out of memory case in which data could be written one page
366off in the page cache.
Steve French11aa0142005-04-28 22:41:10 -0700367
Steve French966ca922005-04-28 22:41:08 -0700368Version 1.33
369------------
370Fix caching problem, in which readdir of directory containing a file
371which was cached could cause the file's time stamp to be updated
372without invalidating the readahead data (so we could get stale
373file data on the client for that file even as the server copy changed).
Steve Frenchcd634992005-04-28 22:41:10 -0700374Cleanup response processing so cifsd can not loop when abnormally
375terminated.
Steve French966ca922005-04-28 22:41:08 -0700376
377
Steve Frenchf654bac2005-04-28 22:41:04 -0700378Version 1.32
Linus Torvalds1da177e2005-04-16 15:20:36 -0700379------------
380Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
381transact response for an SMB request and search entry split across two frames.
Steve Frenchf654bac2005-04-28 22:41:04 -0700382Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
383as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
384unless server explicitly claims to support them in CIFS Unix extensions
Steve Frenchad009ac2005-04-28 22:41:05 -0700385POSIX ACL capability bit. Fix packet signing when multiuser mounting with
Steve Frenchcbe04762005-04-28 22:41:05 -0700386different users from the same client to the same server. Fix oops in
Steve French6a0b4822005-04-28 22:41:05 -0700387cifs_close. Add mount option for remapping reserved characters in
388filenames (also allow recognizing files with created by SFU which have any
Steve French737b7582005-04-28 22:41:06 -0700389of these seven reserved characters, except backslash, to be recognized).
Steve French848f3fc2005-04-28 22:41:07 -0700390Fix invalid transact2 message (we were sometimes trying to interpret
Steve French099a58f2005-04-28 22:41:07 -0700391oplock breaks as SMB responses). Add ioctl for checking that the
392current uid matches the uid of the mounter (needed by umount.cifs).
393Reduce the number of large buffer allocations in cifs response processing
394(significantly reduces memory pressure under heavy stress with multiple
395processes accessing the same server at the same time).
Steve Frenchf654bac2005-04-28 22:41:04 -0700396
397Version 1.31
398------------
Linus Torvalds1da177e2005-04-16 15:20:36 -0700399Fix updates of DOS attributes and time fields so that files on NT4 servers
400do not get marked delete on close. Display sizes of cifs buffer pools in
401cifs stats. Fix oops in unmount when cifsd thread being killed by
402shutdown. Add generic readv/writev and aio support. Report inode numbers
403consistently in readdir and lookup (when serverino mount option is
404specified use the inode number that the server reports - for both lookup
405and readdir, otherwise by default the locally generated inode number is used
406for inodes created in either path since servers are not always able to
407provide unique inode numbers when exporting multiple volumes from under one
408sharename).
409
410Version 1.30
411------------
412Allow new nouser_xattr mount parm to disable xattr support for user namespace.
413Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
414(mostly affects NT4 servers) by retry with handle based network operation.
415Add new POSIX Query FS Info for returning statfs info more accurately.
416Handle passwords with multiple commas in them.
417
418Version 1.29
419------------
420Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
421Fix capabilities flags for large readx so as to allow reads larger than 64K.
422
423Version 1.28
424------------
425Add module init parm for large SMB buffer size (to allow it to be changed
426from its default of 16K) which is especially useful for large file copy
427when mounting with the directio mount option. Fix oops after
428returning from mount when experimental ExtendedSecurity enabled and
429SpnegoNegotiated returning invalid error. Fix case to retry better when
430peek returns from 1 to 3 bytes on socket which should have more data.
431Fixed path based calls (such as cifs lookup) to handle path names
432longer than 530 (now can handle PATH_MAX). Fix pass through authentication
433from Samba server to DC (Samba required dummy LM password).
434
435Version 1.27
436------------
437Turn off DNOTIFY (directory change notification support) by default
438(unless built with the experimental flag) to fix hang with KDE
439file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
440waiting on an SMB response) in SendReceive when session dies but
441reconnects quickly from another task. Add module init parms for
442minimum number of large and small network buffers in the buffer pools,
443and for the maximum number of simultaneous requests.
444
445Version 1.26
446------------
447Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
448and other POSIX CIFS compliant servers. Fix error mapping for getfacl
449to EOPNOTSUPP when server does not support posix acls on the wire. Fix
450improperly zeroed buffer in CIFS Unix extensions set times call.
451
452Version 1.25
453------------
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700454Fix internationalization problem in cifs readdir with filenames that map to
Alexey Dobriyan4de151d2006-03-22 00:13:35 +0100455longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
Linus Torvalds1da177e2005-04-16 15:20:36 -0700456for readdir to netapp servers. Fix search rewind (seek into readdir to return
457non-consecutive entries). Do not do readdir when server negotiates
458buffer size to small to fit filename. Add support for reading POSIX ACLs from
459the server (add also acl and noacl mount options).
460
461Version 1.24
462------------
463Optionally allow using server side inode numbers, rather than client generated
464ones by specifying mount option "serverino" - this is required for some apps
465to work which double check hardlinked files and have persistent inode numbers.
466
467Version 1.23
468------------
469Multiple bigendian fixes. On little endian systems (for reconnect after
470network failure) fix tcp session reconnect code so we do not try first
471to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
472as directories rather than symlinks because we can do follow link on them.
473
474Version 1.22
475------------
476Add config option to enable XATTR (extended attribute) support, mapping
477xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
478minor fixes pointed out by the Stanford SWAT checker (mostly missing
479or out of order NULL pointer checks in little used error paths).
480
481Version 1.21
482------------
483Add new mount parm to control whether mode check (generic_permission) is done
484on the client. If Unix extensions are enabled and the uids on the client
485and server do not match, client permission checks are meaningless on
486server uids that do not exist on the client (this does not affect the
487normal ACL check which occurs on the server). Fix default uid
488on mknod to match create and mkdir. Add optional mount parm to allow
489override of the default uid behavior (in which the server sets the uid
490and gid of newly created files). Normally for network filesystem mounts
491user want the server to set the uid/gid on newly created files (rather than
492using uid of the client processes you would in a local filesystem).
493
494Version 1.20
495------------
496Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
497info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
498(in build_wildcard_path_from_dentry). Fix mknod to pass type field
499(block/char/fifo) properly. Remove spurious mount warning log entry when
500credentials passed as mount argument. Set major/minor device number in
501inode for block and char devices when unix extensions enabled.
502
503Version 1.19
504------------
505Fix /proc/fs/cifs/Stats and DebugData display to handle larger
506amounts of return data. Properly limit requests to MAX_REQ (50
507is the usual maximum active multiplex SMB/CIFS requests per server).
508Do not kill cifsd (and thus hurt the other SMB session) when more than one
509session to the same server (but with different userids) exists and one
510of the two user's smb sessions is being removed while leaving the other.
511Do not loop reconnecting in cifsd demultiplex thread when admin
512kills the thread without going through unmount.
513
514Version 1.18
515------------
516Do not rename hardlinked files (since that should be a noop). Flush
517cached write behind data when reopening a file after session abend,
518except when already in write. Grab per socket sem during reconnect
519to avoid oops in sendmsg if overlapping with reconnect. Do not
520reset cached inode file size on readdir for files open for write on
521client.
522
523
524Version 1.17
525------------
526Update number of blocks in file so du command is happier (in Linux a fake
527blocksize of 512 is required for calculating number of blocks in inode).
528Fix prepare write of partial pages to read in data from server if possible.
529Fix race on tcpStatus field between unmount and reconnection code, causing
530cifsd process sometimes to hang around forever. Improve out of memory
531checks in cifs_filldir
532
533Version 1.16
534------------
535Fix incorrect file size in file handle based setattr on big endian hardware.
536Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
537and closing file structs in writepage/partialpagewrite. Add statistics
538for each mounted share (new menuconfig option). Fix endianness problem in
539volume information displayed in /proc/fs/cifs/DebugData (only affects
540affects big endian architectures). Prevent renames while constructing
541path names for open, mkdir and rmdir.
542
543Version 1.15
544------------
545Change to mempools for alloc smb request buffers and multiplex structs
546to better handle low memory problems (and potential deadlocks).
547
548Version 1.14
549------------
550Fix incomplete listings of large directories on Samba servers when Unix
551extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
552rename deadlock when writing out dirty pages at same time.
553
554Version 1.13
555------------
556Fix open of files in which O_CREATE can cause the mode to change in
557some cases. Fix case in which retry of write overlaps file close.
558Fix PPC64 build error. Reduce excessive stack usage in smb password
559hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
560
561Version 1.12
562------------
563Fixes for large file copy, signal handling, socket retry, buffer
564allocation and low memory situations.
565
566Version 1.11
567------------
568Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
569also now allowing support for specifying client netbiosname. NT4 support added.
570
571Version 1.10
572------------
573Fix reconnection (and certain failed mounts) to properly wake up the
574blocked users thread so it does not seem hung (in some cases was blocked
575until the cifs receive timeout expired). Fix spurious error logging
576to kernel log when application with open network files killed.
577
578Version 1.09
579------------
580Fix /proc/fs module unload warning message (that could be logged
581to the kernel log). Fix intermittent failure in connectathon
582test7 (hardlink count not immediately refreshed in case in which
583inode metadata can be incorrectly kept cached when time near zero)
584
585Version 1.08
586------------
587Allow file_mode and dir_mode (specified at mount time) to be enforced
588locally (the server already enforced its own ACLs too) for servers
589that do not report the correct mode (do not support the
590CIFS Unix Extensions).
591
592Version 1.07
593------------
594Fix some small memory leaks in some unmount error paths. Fix major leak
595of cache pages in readpages causing multiple read oriented stress
596testcases (including fsx, and even large file copy) to fail over time.
597
598Version 1.06
599------------
600Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
601This allows files that differ only in case and improves performance of file
602creation and file open to such servers. Fix semaphore conflict which causes
603slow delete of open file to Samba (which unfortunately can cause an oplock
604break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
605
606Version 1.05
607------------
608fixes to cifs_readpages for fsx test case
609
610Version 1.04
611------------
612Fix caching data integrity bug when extending file size especially when no
613oplock on file. Fix spurious logging of valid already parsed mount options
614that are parsed outside of the cifs vfs such as nosuid.
615
616
617Version 1.03
618------------
619Connect to server when port number override not specified, and tcp port
620unitialized. Reset search to restart at correct file when kernel routine
621filldir returns error during large directory searches (readdir).
622
623Version 1.02
624------------
625Fix caching problem when files opened by multiple clients in which
626page cache could contain stale data, and write through did
627not occur often enough while file was still open when read ahead
628(read oplock) not allowed. Treat "sep=" when first mount option
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700629as an override of comma as the default separator between mount
Linus Torvalds1da177e2005-04-16 15:20:36 -0700630options.
631
632Version 1.01
633------------
634Allow passwords longer than 16 bytes. Allow null password string.
635
636Version 1.00
637------------
638Gracefully clean up failed mounts when attempting to mount to servers such as
Steve Frenchc0c3e8e2005-08-24 14:01:13 -0700639Windows 98 that terminate tcp sessions during protocol negotiation. Handle
Linus Torvalds1da177e2005-04-16 15:20:36 -0700640embedded commas in mount parsing of passwords.
641
642Version 0.99
643------------
644Invalidate local inode cached pages on oplock break and when last file
645instance is closed so that the client does not continue using stale local
646copy rather than later modified server copy of file. Do not reconnect

837
838
839Version 0.67
840------------
841Fix signal sending so that captive thread (cifsd) exits on umount
842(which was causing the warning in kmem_cache_free of the request buffers
843at rmmod time). This had broken as a sideeffect of the recent global
844kernel change to daemonize. Fix memory leak in readdir code which
845showed up in "ls -R" (and applications that did search rewinding).
846
847Version 0.66
848------------

871
872Version 0.62
873------------
874Fix temporary socket leak when bad userid or password specified
875(or other SMBSessSetup failure). Increase maximum buffer size to slightly

877sizes. Add support for readpages
878
879Version 0.61
880------------
881Fix oops when username not passed in on mount. Extensive fixes and improvements
882to error logging (strip redundant newlines, change debug macros to ensure newline
883passed in and to be more consistent). Fix writepage wrong file handle problem,
884a readonly file handle could be incorrectly used to attempt to write out
885file updates through the page cache to multiply open files. This could cause
886the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
887shares to the same Windows server when using different usernames
888(doing this to Samba servers worked but Windows was rejecting it) - now it is
889possible to use different userids when connecting to the same server from a
890Linux client. Fix oops when treeDisconnect called during unmount on
891previously freed socket.

10371) Fixed lockrange to be correct (it was one byte too short)
1038
10392) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
1040show range as locked when there is a conflict with an existing lock.
1041
10423) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
1043in most cases. Eventually will offer optional ability to query server for the correct perms.
1044
10453) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
1046but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
1047session)
1048
10494) Fixed error logging of valid mount options
1050
10515) Removed logging of password field.
1052
