3 Add "forcemandatorylock" mount option to allow user to use mandatory
4 rather than posix (advisory) byte range locks, even though server would
5 support posix byte range locks. Fix query of root inode when prefixpath
6 specified and user does not have access to query information about the
7 top of the share. Fix problem in 2.6.28 resolving DFS paths to
8 Samba servers (worked to Windows). Fix rmdir so that pending search
9 (readdir) requests do not get invalid results which include the now
10 removed directory. Fix oops in cifs_dfs_ref.c when prefixpath is not reachable
15 Various fixes to make delete of open files behavior more predictable
16 (when delete of an open file fails we mark the file as "delete-on-close"
17 in a way that more servers accept, but only if we can first rename the
18 file to a temporary name). Add experimental support for more safely
19 handling fcntl(F_SETLEASE). Convert cifs to using blocking tcp
20 sends, and also let tcp autotune the socket send and receive buffers.
21 This reduces the number of EAGAIN errors returned by TCP/IP in
22 high stress workloads (and the number of retries on socket writes
23 when sending large SMBWriteX requests). Fix case in which a portion of
24 data can in some cases not get written to the file on the server before the
25 file is closed. Fix DFS parsing to properly handle path consumed field,
26 and to handle certain codepage conversions better. Fix mount and
27 umount race that can cause oops in mount or umount or reconnect.
31 Fix premature write failure on congested networks (we would give up
32 on EAGAIN from the socket too quickly on large writes).
33 Cifs_mkdir and cifs_create now respect the setgid bit on parent dir.
34 Fix endian problems in acl (mode from/to cifs acl) on bigendian
35 architectures. Fix problems with preserving timestamps on copying open
36 files (e.g. "cp -a") to Windows servers. For mkdir and create honor setgid bit
37 on parent directory when server supports Unix Extensions but not POSIX
38 create. Update cifs.upcall version to handle new Kerberos sec flags
39 (this requires update of cifs.upcall program from Samba). Fix memory leak
40 on dns_upcall (resolving DFS referralls). Fix plain text password
41 authentication (requires setting SecurityFlags to 0x30030 to enable
42 lanman and plain text though). Fix writes to be at correct offset when
43 file is open with O_APPEND and file is on a directio (forcediretio) mount.
44 Fix bug in rewinding readdir directory searches. Add nodfs mount option.
48 DFS support added (Microsoft Distributed File System client support needed
49 for referrals which enable a hierarchical name space among servers).
50 Disable temporary caching of mode bits to servers which do not support
51 storing of mode (e.g. Windows servers, when client mounts without cifsacl
52 mount option) and add new "dynperm" mount option to enable temporary caching
53 of mode (enable old behavior). Fix hang on mount caused when server crashes
54 tcp session during negotiate protocol.
58 Fix oops on second mount to server when null auth is used.
59 Enable experimental Kerberos support. Return writebehind errors on flush
60 and sync so that events like out of disk space get reported properly on
61 cached files. Fix setxattr failure to certain Samba versions. Fix mount
62 of second share to disconnected server session (autoreconnect on this).
63 Add ability to modify cifs acls for handling chmod (when mounted with
64 cifsacl flag). Fix prefixpath path separator so we can handle mounts
65 with prefixpaths longer than one directory (one path component) when
66 mounted to Windows servers. Fix slow file open when cifsacl
67 enabled. Fix memory leak in FindNext when the SMB call returns -EBADF.
72 Fix memory leak in statfs when mounted to very old servers (e.g.
73 Windows 9x). Add new feature "POSIX open" which allows servers
74 which support the current POSIX Extensions to provide better semantics
75 (e.g. delete for open files opened with posix open). Take into
76 account umask on posix mkdir not just older style mkdir. Add
77 ability to mount to IPC$ share (which allows CIFS named pipes to be
78 opened, read and written as if they were files). When 1st tree
79 connect fails (e.g. due to signing negotiation failure) fix
80 leak that causes cifsd not to stop and rmmod to fail to cleanup
81 cifs_request_buffers pool. Fix problem with POSIX Open/Mkdir on
82 bigendian architectures. Fix possible memory corruption when
83 EAGAIN returned on kern_recvmsg. Return better error if server
84 requires packet signing but client has disabled it. When mounted
85 with cifsacl mount option - mode bits are approximated based
86 on the contents of the ACL of the file or directory. When cifs
87 mount helper is missing convert make sure that UNC name
88 has backslash (not forward slash) between ip address of server
93 Fix NTLMv2 signing. NFS server mounted over cifs works (if cifs mount is
94 done with "serverino" mount option). Add support for POSIX Unlink
95 (helps with certain sharing violation cases when server such as
96 Samba supports newer POSIX CIFS Protocol Extensions). Add "nounix"
97 mount option to allow disabling the CIFS Unix Extensions for just
98 that mount. Fix hang on spinlock in find_writable_file (race when
99 reopening file after session crash). Byte range unlock request to
100 windows server could unlock more bytes (on server copy of file)
101 than intended if start of unlock request is well before start of
102 a previous byte range lock that we issued.
106 IPv6 support. Enable ipv6 addresses to be passed on mount (put the ipv6
107 address after the "ip=" mount option, at least until mount.cifs is fixed to
108 handle DNS host to ipv6 name translation). Accept override of uid or gid
109 on mount even when Unix Extensions are negotiated (it used to be ignored
110 when Unix Extensions were ignored). This allows users to override the
111 default uid and gid for files when they are certain that the uids or
112 gids on the server do not match those of the client. Make "sec=none"
113 mount override username (so that null user connection is attempted)
114 to match what documentation said. Support for very large reads, over 127K,
115 available to some newer servers (such as Samba 3.0.26 and later but
116 note that it also requires setting CIFSMaxBufSize at module install
117 time to a larger value which may hurt performance in some cases).
118 Make sign option force signing (or fail if server does not support it).
122 Fix mtime bouncing around from local idea of last write times to remote time.
123 Fix hang (in i_size_read) when simultaneous size update of same remote file
124 on smp system corrupts sequence number. Do not reread unnecessarily partial page
125 (which we are about to overwrite anyway) when writing out file opened rw.
126 When DOS attribute of file on non-Unix server's file changes on the server side
127 from read-only back to read-write, reflect this change in default file mode
128 (we had been leaving a file's mode read-only until the inode were reloaded).
129 Allow setting of attribute back to ATTR_NORMAL (removing readonly dos attribute
130 when archive dos attribute not set and we are changing mode back to writeable
131 on server which does not support the Unix Extensions). Remove read only dos
132 attribute on chmod when adding any write permission (ie on any of
133 user/group/other (not all of user/group/other ie 0222) when
134 mounted to windows. Add support for POSIX MkDir (slight performance
135 enhancement and eliminates the network race between the mkdir and set
136 path info of the mode).
141 Fix oops in list_del during mount caused by unaligned string.
142 Fix file corruption which could occur on some large file
143 copies caused by writepages page i/o completion bug.
144 Seek to SEEK_END forces check for update of file size for non-cached
145 files. Allow file size to be updated on remote extend of locally open,
146 non-cached file. Fix reconnect to newer Samba servers (or other servers
147 which support the CIFS Unix/POSIX extensions) so that we again tell the
148 server the Unix/POSIX cifs capabilities which we support (SetFSInfo).
149 Add experimental support for new POSIX Open/Mkdir (which returns
150 stat information on the open, and allows setting the mode).
154 Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
155 Allow null user to be specified on mount ("username="). Do not return
156 EINVAL on readdir when filldir fails due to overwritten blocksize
157 (fixes FC problem). Return error in rename 2nd attempt retry (ie report
158 if rename by handle also fails, after rename by path fails, we were
159 not reporting whether the retry worked or not). Fix NTLMv2 to
160 work to Windows servers (mount with option "sec=ntlmv2").
164 Do not time out lockw calls when using posix extensions. Do not
165 time out requests if server still responding reasonably fast
166 on requests on other threads. Improve POSIX locking emulation,
167 (lock cancel now works, and unlock of merged range works even
168 to Windows servers now). Fix oops on mount to lanman servers
169 (win9x, os/2 etc.) when null password. Do not send listxattr
170 (SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
171 problem (instantiate inodes/dentries in right order for readdir).
175 Rewritten sessionsetup support, including support for legacy SMB
176 session setup needed for OS/2 and older servers such as Windows 95 and 98.
177 Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
178 so we can do search (ls etc.) to OS/2. Do not send NTCreateX
179 or recent levels of FindFirst unless server says it supports NT SMBs
180 (instead use legacy equivalents from LANMAN dialect). Fix to allow
181 NTLMv2 authentication support (now can use stronger password hashing
182 on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
183 Allow override of global cifs security flags on mount via "sec=" option(s).
187 POSIX locking to servers which support CIFS POSIX Extensions
188 (disabled by default controlled by proc/fs/cifs/Experimental).
189 Handle conversion of long share names (especially Asian languages)
190 to Unicode during mount. Fix memory leak in sess struct on reconnect.
191 Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
192 cifs open which helps rare case when setpathinfo fails or server does
197 Fix slow oplock break when mounted to different servers at the same time and
198 the tids match and we try to find matching fid on wrong server. Fix read
199 looping when signing required by server (2.6.16 kernel only). Fix readdir
200 vs. rename race which could cause each to hang. Return . and .. even
201 if server does not. Allow searches to skip first three entries and
202 begin at any location. Fix oops in find_writeable_file.
206 Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
207 configure stronger authentication. Fix sfu symlinks so they can
208 be followed (not just recognized). Fix wraparound of bcc on
209 read responses when buffer size over 64K and also fix wrap of
210 max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
211 cifs_user_read and cifs_readpages (when EAGAIN on send of smb
212 on socket is returned over and over). Add POSIX (advisory) byte range
213 locking support (requires server with newest CIFS UNIX Extensions
214 to the protocol implemented). Slow down negprot slightly in port 139
215 RFC1001 case to give session_init time on buggy servers.
219 Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
220 of readpages by eliminating one extra memcpy. Allow update of file size
221 from remote server even if file is open for write as long as mount is
222 directio. Recognize share mode security and send NTLM encrypted password
223 on tree connect if share mode negotiated.
227 Defer close of a file handle slightly if pending writes depend on that handle
228 (this reduces the EBADF bad file handle errors that can be logged under heavy
229 stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
230 Fix SFU style symlinks and mknod needed for servers which do not support the
231 CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
232 dentries so files that the client sees as deleted but that later get created
233 on the server will be recognized. Add client side permission check on setattr.
234 Timeout stuck requests better (where server has never responded or sent corrupt
239 Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
240 to be smaller at first (but increasing) so large write performance performance
241 over GigE is better. Do not hang thread on illegal byte range lock response
242 from Windows (Windows can send an RFC1001 size which does not match smb size) by
243 allowing an SMBs TCP length to be up to a few bytes longer than it should be.
244 wsize and rsize can now be larger than negotiated buffer size if server
245 supports large readx/writex, even when directio mount flag not specified.
246 Write size will in many cases now be 16K instead of 4K which greatly helps
247 file copy performance on lightly loaded networks. Fix oops in dnotify
248 when experimental config flag enabled. Make cifsFYI more granular.
252 Fix readdir caching when unlink removes file in current search buffer,
253 and this is followed by a rewind search to just before the deleted entry.
254 Do not attempt to set ctime unless atime and/or mtime change requested
255 (most servers throw it away anyway). Fix length check of received smbs
256 to be more accurate. Fix big endian problem with mapchars mount option,
257 and with a field returned by statfs.
261 Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
262 For these older servers, add option for passing netbios name of server in
263 on mount (servernetbiosname). Add suspend support for power management, to
264 avoid cifsd thread preventing software suspend from working.
265 Add mount option for disabling the default behavior of sending byte range lock
266 requests to the server (necessary for certain applications which break with
267 mandatory lock behavior such as Evolution), and also mount option for
268 requesting case insensitive matching for path based requests (requesting
269 case sensitive is the default).
273 Add writepage performance improvements. Fix path name conversions
274 for long filenames on mounts which were done with "mapchars" mount option
275 specified. Ensure multiplex ids do not collide. Fix case in which
276 rmmod can oops if done soon after last unmount. Fix truncated
277 search (readdir) output when resume filename was a long filename.
278 Fix filename conversion when mapchars mount option was specified and
279 filename was a long filename.
283 Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
284 Do not oops if root user kills cifs oplock kernel thread or
285 kills the cifsd thread (NB: killing the cifs kernel threads is not
286 recommended, unmount and rmmod cifs will kill them when they are
287 no longer needed). Fix readdir to ASCII servers (ie older servers
288 which do not support Unicode) and also require asterisk.
289 Fix out of memory case in which data could be written one page
290 off in the page cache.
294 Fix caching problem, in which readdir of directory containing a file
295 which was cached could cause the file's time stamp to be updated
296 without invalidating the readahead data (so we could get stale
297 file data on the client for that file even as the server copy changed).
298 Cleanup response processing so cifsd can not loop when abnormally
304 Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
305 transact response for an SMB request and search entry split across two frames.
306 Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
307 as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
308 unless server explicitly claims to support them in CIFS Unix extensions
309 POSIX ACL capability bit. Fix packet signing when multiuser mounting with
310 different users from the same client to the same server. Fix oops in
311 cifs_close. Add mount option for remapping reserved characters in
312 filenames (also allow recognizing files with created by SFU which have any
313 of these seven reserved characters, except backslash, to be recognized).
314 Fix invalid transact2 message (we were sometimes trying to interpret
315 oplock breaks as SMB responses). Add ioctl for checking that the
316 current uid matches the uid of the mounter (needed by umount.cifs).
317 Reduce the number of large buffer allocations in cifs response processing
318 (significantly reduces memory pressure under heavy stress with multiple
319 processes accessing the same server at the same time).
323 Fix updates of DOS attributes and time fields so that files on NT4 servers
324 do not get marked delete on close. Display sizes of cifs buffer pools in
325 cifs stats. Fix oops in unmount when cifsd thread being killed by
326 shutdown. Add generic readv/writev and aio support. Report inode numbers
327 consistently in readdir and lookup (when serverino mount option is
328 specified use the inode number that the server reports - for both lookup
329 and readdir, otherwise by default the locally generated inode number is used
330 for inodes created in either path since servers are not always able to
331 provide unique inode numbers when exporting multiple volumes from under one
336 Allow new nouser_xattr mount parm to disable xattr support for user namespace.
337 Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
338 (mostly affects NT4 servers) by retry with handle based network operation.
339 Add new POSIX Query FS Info for returning statfs info more accurately.
340 Handle passwords with multiple commas in them.
344 Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
345 Fix capabilities flags for large readx so as to allow reads larger than 64K.
349 Add module init parm for large SMB buffer size (to allow it to be changed
350 from its default of 16K) which is especially useful for large file copy
351 when mounting with the directio mount option. Fix oops after
352 returning from mount when experimental ExtendedSecurity enabled and
353 SpnegoNegotiated returning invalid error. Fix case to retry better when
354 peek returns from 1 to 3 bytes on socket which should have more data.
355 Fixed path based calls (such as cifs lookup) to handle path names
356 longer than 530 (now can handle PATH_MAX). Fix pass through authentication
357 from Samba server to DC (Samba required dummy LM password).
361 Turn off DNOTIFY (directory change notification support) by default
362 (unless built with the experimental flag) to fix hang with KDE
363 file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
364 waiting on an SMB response) in SendReceive when session dies but
365 reconnects quickly from another task. Add module init parms for
366 minimum number of large and small network buffers in the buffer pools,
367 and for the maximum number of simultaneous requests.
371 Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
372 and other POSIX CIFS compliant servers. Fix error mapping for getfacl
373 to EOPNOTSUPP when server does not support posix acls on the wire. Fix
374 improperly zeroed buffer in CIFS Unix extensions set times call.
378 Fix internationalization problem in cifs readdir with filenames that map to
379 longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
380 for readdir to netapp servers. Fix search rewind (seek into readdir to return
381 non-consecutive entries). Do not do readdir when server negotiates
382 buffer size to small to fit filename. Add support for reading POSIX ACLs from
383 the server (add also acl and noacl mount options).
387 Optionally allow using server side inode numbers, rather than client generated
388 ones by specifying mount option "serverino" - this is required for some apps
389 to work which double check hardlinked files and have persistent inode numbers.
393 Multiple bigendian fixes. On little endian systems (for reconnect after
394 network failure) fix tcp session reconnect code so we do not try first
395 to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
396 as directories rather than symlinks because we can do follow link on them.
400 Add config option to enable XATTR (extended attribute) support, mapping
401 xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
402 minor fixes pointed out by the Stanford SWAT checker (mostly missing
403 or out of order NULL pointer checks in little used error paths).
407 Add new mount parm to control whether mode check (generic_permission) is done
408 on the client. If Unix extensions are enabled and the uids on the client
409 and server do not match, client permission checks are meaningless on
410 server uids that do not exist on the client (this does not affect the
411 normal ACL check which occurs on the server). Fix default uid
412 on mknod to match create and mkdir. Add optional mount parm to allow
413 override of the default uid behavior (in which the server sets the uid
414 and gid of newly created files). Normally for network filesystem mounts
415 user want the server to set the uid/gid on newly created files (rather than
416 using uid of the client processes you would in a local filesystem).
420 Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
421 info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
422 (in build_wildcard_path_from_dentry). Fix mknod to pass type field
423 (block/char/fifo) properly. Remove spurious mount warning log entry when
424 credentials passed as mount argument. Set major/minor device number in
425 inode for block and char devices when unix extensions enabled.
429 Fix /proc/fs/cifs/Stats and DebugData display to handle larger
430 amounts of return data. Properly limit requests to MAX_REQ (50
431 is the usual maximum active multiplex SMB/CIFS requests per server).
432 Do not kill cifsd (and thus hurt the other SMB session) when more than one
433 session to the same server (but with different userids) exists and one
434 of the two user's smb sessions is being removed while leaving the other.
435 Do not loop reconnecting in cifsd demultiplex thread when admin
436 kills the thread without going through unmount.
440 Do not rename hardlinked files (since that should be a noop). Flush
441 cached write behind data when reopening a file after session abend,
442 except when already in write. Grab per socket sem during reconnect
443 to avoid oops in sendmsg if overlapping with reconnect. Do not
444 reset cached inode file size on readdir for files open for write on
450 Update number of blocks in file so du command is happier (in Linux a fake
451 blocksize of 512 is required for calculating number of blocks in inode).
452 Fix prepare write of partial pages to read in data from server if possible.
453 Fix race on tcpStatus field between unmount and reconnection code, causing
454 cifsd process sometimes to hang around forever. Improve out of memory
455 checks in cifs_filldir
459 Fix incorrect file size in file handle based setattr on big endian hardware.
460 Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
461 and closing file structs in writepage/partialpagewrite. Add statistics
462 for each mounted share (new menuconfig option). Fix endianness problem in
463 volume information displayed in /proc/fs/cifs/DebugData (only affects
464 affects big endian architectures). Prevent renames while constructing
465 path names for open, mkdir and rmdir.
469 Change to mempools for alloc smb request buffers and multiplex structs
470 to better handle low memory problems (and potential deadlocks).
474 Fix incomplete listings of large directories on Samba servers when Unix
475 extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
476 rename deadlock when writing out dirty pages at same time.
480 Fix open of files in which O_CREATE can cause the mode to change in
481 some cases. Fix case in which retry of write overlaps file close.
482 Fix PPC64 build error. Reduce excessive stack usage in smb password
483 hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
487 Fixes for large file copy, signal handling, socket retry, buffer
488 allocation and low memory situations.
492 Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
493 also now allowing support for specifying client netbiosname. NT4 support added.
497 Fix reconnection (and certain failed mounts) to properly wake up the
498 blocked users thread so it does not seem hung (in some cases was blocked
499 until the cifs receive timeout expired). Fix spurious error logging
500 to kernel log when application with open network files killed.
504 Fix /proc/fs module unload warning message (that could be logged
505 to the kernel log). Fix intermittent failure in connectathon
506 test7 (hardlink count not immediately refreshed in case in which
507 inode metadata can be incorrectly kept cached when time near zero)
511 Allow file_mode and dir_mode (specified at mount time) to be enforced
512 locally (the server already enforced its own ACLs too) for servers
513 that do not report the correct mode (do not support the
514 CIFS Unix Extensions).
518 Fix some small memory leaks in some unmount error paths. Fix major leak
519 of cache pages in readpages causing multiple read oriented stress
520 testcases (including fsx, and even large file copy) to fail over time.
524 Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
525 This allows files that differ only in case and improves performance of file
526 creation and file open to such servers. Fix semaphore conflict which causes
527 slow delete of open file to Samba (which unfortunately can cause an oplock
528 break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
532 fixes to cifs_readpages for fsx test case
536 Fix caching data integrity bug when extending file size especially when no
537 oplock on file. Fix spurious logging of valid already parsed mount options
538 that are parsed outside of the cifs vfs such as nosuid.
543 Connect to server when port number override not specified, and tcp port
544 unitialized. Reset search to restart at correct file when kernel routine
545 filldir returns error during large directory searches (readdir).
549 Fix caching problem when files opened by multiple clients in which
550 page cache could contain stale data, and write through did
551 not occur often enough while file was still open when read ahead
552 (read oplock) not allowed. Treat "sep=" when first mount option
553 as an override of comma as the default separator between mount
558 Allow passwords longer than 16 bytes. Allow null password string.
562 Gracefully clean up failed mounts when attempting to mount to servers such as
563 Windows 98 that terminate tcp sessions during protocol negotiation. Handle
564 embedded commas in mount parsing of passwords.
568 Invalidate local inode cached pages on oplock break and when last file
569 instance is closed so that the client does not continue using stale local
570 copy rather than later modified server copy of file. Do not reconnect
571 when server drops the tcp session prematurely before negotiate
572 protocol response. Fix oops in reopen_file when dentry freed. Allow
573 the support for CIFS Unix Extensions to be disabled via proc interface.
577 Fix hang in commit_write during reconnection of open files under heavy load.
578 Fix unload_nls oops in a mount failure path. Serialize writes to same socket
579 which also fixes any possible races when cifs signatures are enabled in SMBs
580 being sent out of signature sequence number order.
584 Fix byte range locking bug (endian problem) causing bad offset and
589 Fix oops (in send_sig) caused by CIFS unmount code trying to
590 wake up the demultiplex thread after it had exited. Do not log
591 error on harmless oplock release of closed handle.
595 Fix unsafe global variable usage and password hash failure on gcc 3.3.1
596 Fix problem reconnecting secondary mounts to same server after session
597 failure. Fix invalid dentry - race in mkdir when directory gets created
598 by another client between the lookup and mkdir.
602 Fix to list processing in reopen_files. Fix reconnection when server hung
603 but tcpip session still alive. Set proper timeout on socket read.
607 Add missing mount options including iocharset. SMP fixes in write and open.
608 Fix errors in reconnecting after TCP session failure. Fix module unloading
609 of default nls codepage
613 Active smb transactions should never go negative (fix double FreeXid). Fix
614 list processing in file routines. Check return code on kmalloc in open.
615 Fix spinlock usage for SMP.
619 Fix oops in reopen_files when invalid dentry. drop dentry on server rename
620 and on revalidate errors. Fix cases where pid is now tgid. Fix return code
621 on create hard link when server does not support them.
625 Fix scheduling while atomic error in getting inode info on newly created file.
626 Fix truncate of existing files opened with O_CREAT but not O_TRUNC set.
630 Fix oops on write to dead tcp session. Remove error log write for case when file open
631 O_CREAT but not O_EXCL
635 Fix non-POSIX behavior on rename of open file and delete of open file by taking
636 advantage of trans2 SetFileInfo rename facility if available on target server.
637 Retry on ENOSPC and EAGAIN socket errors.
641 Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix
642 allocation size miscalculation. After oplock token lost do not read through
647 Fix oops on empty file readahead. Fix for file size handling for locally cached files.
651 Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files
652 during auto reconnection to server after server recovered from failure.
656 Finish support for Linux 2.5 open/create changes, which removes the
657 redundant NTCreate/QPathInfo/close that was sent during file create.
658 Enable oplock by default. Enable packet signing by default (needed to
659 access many recent Windows servers)
663 Fix oops when mounting to long server names caused by inverted parms to kmalloc.
664 Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
665 we will choose a cifs user session (smb uid) that better matches the local
666 uid if a) the mount uid does not match the current uid and b) we have another
667 session to the same server (ip address) for a different mount which
668 matches the current local uid.
672 Add support for mknod of block or character devices. Fix oplock
673 code (distributed caching) to properly send response to oplock
678 Finish up CIFS packet digital signing for the default
679 NTLM security case. This should help Windows 2003
680 network interoperability since it is common for
681 packet signing to be required now. Fix statfs (stat -f)
682 which recently started returning errors due to
683 invalid value (-1 instead of 0) being set in the
684 struct kstatfs f_ffiles field.
688 Fix oops on stopping oplock thread when removing cifs when
693 Fix mount options for ro (readonly), uid, gid and file and directory mode.
697 Fix errors displayed on failed mounts to be more understandable.
698 Fixed various incorrect or misleading smb to posix error code mappings.
702 Fix display of NTFS DFS junctions to display as symlinks.
703 They are the network equivalent. Fix oops in
704 cifs_partialpagewrite caused by missing spinlock protection
705 of openfile linked list. Allow writebehind caching errors to
706 be returned to the application at file close.
710 Clean up options displayed in /proc/mounts by show_options to
711 be more consistent with other filesystems.
715 Fix delete of readonly file to Windows servers. Reflect
716 presence or absence of read only dos attribute in mode
717 bits for servers that do not support CIFS Unix extensions.
718 Fix shortened results on readdir of large directories to
719 servers supporting CIFS Unix extensions (caused by
720 incorrect resume key).
724 Fix truncate bug (set file size) that could cause hangs e.g. running fsx
728 unload nls if mount fails.
732 Add resume key support to search (readdir) code to workaround
733 Windows bug. Add /proc/fs/cifs/LookupCacheEnable which
734 allows disabling caching of attribute information for
739 Add more oplock handling (distributed caching code). Remove
740 dead code. Remove excessive stack space utilization from
745 Fix oops in get dfs referral (triggered when null path sent in to
746 mount). Add support for overriding rsize at mount time.
750 Fix buffer overrun in readdir which caused intermittent kernel oopses.
751 Fix writepage code to release kmap on write data. Allow "-ip=" new
752 mount option to be passed in on parameter distinct from the first part
753 (server name portion of) the UNC name. Allow override of the
754 tcp port of the target server via new mount option "-port="
758 Fix search handle leak on rewind. Fix setuid and gid so that they are
759 reflected in the local inode immediately. Cleanup of whitespace
760 to make 2.4 and 2.5 versions more consistent.
765 Fix signal sending so that captive thread (cifsd) exits on umount
766 (which was causing the warning in kmem_cache_free of the request buffers
767 at rmmod time). This had broken as a sideeffect of the recent global
768 kernel change to daemonize. Fix memory leak in readdir code which
769 showed up in "ls -R" (and applications that did search rewinding).
773 Reconnect tids and fids after session reconnection (still do not
774 reconnect byte range locks though). Fix problem caching
775 lookup information for directory inodes, improving performance,
776 especially in deep directory trees. Fix various build warnings.
780 Finish fixes to commit write for caching/readahead consistency. fsx
781 now works to Samba servers. Fix oops caused when readahead
782 was interrupted by a signal.
786 Fix data corruption (in partial page after truncate) that caused fsx to
787 fail to Windows servers. Cleaned up some extraneous error logging in
788 common error paths. Add generic sendfile support.
792 Fix memory leak in AllocMidQEntry.
793 Finish reconnection logic, so connection with server can be dropped
794 (or server rebooted) and the cifs client will reconnect.
798 Fix temporary socket leak when bad userid or password specified
799 (or other SMBSessSetup failure). Increase maximum buffer size to slightly
800 over 16K to allow negotiation of up to Samba and Windows server default read
801 sizes. Add support for readpages
805 Fix oops when username not passed in on mount. Extensive fixes and improvements
806 to error logging (strip redundant newlines, change debug macros to ensure newline
807 passed in and to be more consistent). Fix writepage wrong file handle problem,
808 a readonly file handle could be incorrectly used to attempt to write out
809 file updates through the page cache to multiply open files. This could cause
810 the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
811 shares to the same Windows server when using different usernames
812 (doing this to Samba servers worked but Windows was rejecting it) - now it is
813 possible to use different userids when connecting to the same server from a
814 Linux client. Fix oops when treeDisconnect called during unmount on
815 previously freed socket.
819 Fix oops in readpages caused by not setting address space operations in inode in
824 Includes support for deleting of open files and renaming over existing files (per POSIX
825 requirement). Add readlink support for Windows junction points (directory symlinks).
829 Changed read and write to go through pagecache. Added additional address space operations.
830 Memory mapped operations now working.
834 Added writepage code for additional memory mapping support. Fixed leak in xids causing
835 the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
836 every stat call. Additional formatting cleanup.
840 Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
844 Fixes from Zwane Mwaikambo for adding missing return code checking in a few places.
845 Also included a modified version of his fix to protect global list manipulation of
846 the smb session and tree connection and mid related global variables.
850 Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
851 changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
852 buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
856 More stylistic updates to better match kernel style. Add additional statistics
857 for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
858 and CIFS Packet Signing enablement.
862 Replace call to sleep_on with safer wait_on_event.
863 Make stylistic changes to better match kernel style recommendations.
864 Remove most typedef usage (except for the PDUs themselves).
868 Update mount so the -unc mount option is no longer required (the ip address can be specified
869 in a UNC style device name. Implementation of readpage/writepage started.
873 Fix intermittent problem with incorrect smb header checking on badly
874 fragmented tcp responses
878 Fixes to setting of allocation size and file size.
882 Various 2.5.38 fixes. Now works on 2.5.38
886 Prepare for 2.5 kernel merge. Remove ifdefs.
890 Socket buffer management fixes. Fix dual free.
894 Various big endian fixes for hardlinks and symlinks and also for dfs.
898 Various big endian fixes for servers with Unix extensions such as Samba
902 Various FindNext fixes for incorrect filenames on large directory searches on big endian
903 clients. basic posix file i/o tests now work on big endian machines, not just le
907 SessionSetup and NegotiateProtocol now work from Big Endian machines.
908 Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older
909 versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7).
913 Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
914 files now return the correct number of links on fstat as they are repeatedly linked and unlinked.
918 Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
919 session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
920 Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
921 (which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).
925 Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
926 it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
930 Rewrote much of connection and mount/unmount logic to handle bugs with
931 multiple uses to same share, multiple users to same server etc.
935 Fixed major problem with dentry corruption (missing call to dput)
939 Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
940 Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
941 although corresponding function not fully implemented in the vfs yet
945 Fixed dentry caching bug, misc. cleanup
949 Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
950 on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
951 Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
955 Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
956 and tested against Samba 2.2.5
961 1) Fixed lockrange to be correct (it was one byte too short)
963 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
964 show range as locked when there is a conflict with an existing lock.
966 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
967 in most cases. Eventually will offer optional ability to query server for the correct perms.
969 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
970 but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
973 4) Fixed error logging of valid mount options
975 5) Removed logging of password field.
977 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
978 and cleaned them up and made them more consistent with other cifs functions.
980 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
981 (with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
982 nor is the symlink support using the Unix extensions
984 8) Started adding the readlink and follow_link code
