3 Fix premature write failure on congested networks (we would give up
4 on EAGAIN from the socket too quickly on large writes).
5 Cifs_mkdir and cifs_create now respect the setgid bit on parent dir.
6 Fix endian problems in acl (mode from/to cifs acl) on bigendian
7 architectures. Fix problems with preserving timestamps on copying open
8 files (e.g. "cp -a") to Windows servers. For mkdir and create honor setgid bit
9 on parent directory when server supports Unix Extensions but not POSIX
10 create. Update cifs.upcall version to handle new Kerberos sec flags
11 (this requires update of cifs.upcall program from Samba). Fix memory leak
12 on dns_upcall (resolving DFS referralls). Fix plain text password
13 authentication (requires setting SecurityFlags to 0x30030 to enable
14 lanman and plain text though). Fix writes to be at correct offset when
15 file is open with O_APPEND and file is on a directio (forcediretio) mount.
19 DFS support added (Microsoft Distributed File System client support needed
20 for referrals which enable a hierarchical name space among servers).
21 Disable temporary caching of mode bits to servers which do not support
22 storing of mode (e.g. Windows servers, when client mounts without cifsacl
23 mount option) and add new "dynperm" mount option to enable temporary caching
24 of mode (enable old behavior). Fix hang on mount caused when server crashes
25 tcp session during negotiate protocol.
29 Fix oops on second mount to server when null auth is used.
30 Enable experimental Kerberos support. Return writebehind errors on flush
31 and sync so that events like out of disk space get reported properly on
32 cached files. Fix setxattr failure to certain Samba versions. Fix mount
33 of second share to disconnected server session (autoreconnect on this).
34 Add ability to modify cifs acls for handling chmod (when mounted with
35 cifsacl flag). Fix prefixpath path separator so we can handle mounts
36 with prefixpaths longer than one directory (one path component) when
37 mounted to Windows servers. Fix slow file open when cifsacl
38 enabled. Fix memory leak in FindNext when the SMB call returns -EBADF.
43 Fix memory leak in statfs when mounted to very old servers (e.g.
44 Windows 9x). Add new feature "POSIX open" which allows servers
45 which support the current POSIX Extensions to provide better semantics
46 (e.g. delete for open files opened with posix open). Take into
47 account umask on posix mkdir not just older style mkdir. Add
48 ability to mount to IPC$ share (which allows CIFS named pipes to be
49 opened, read and written as if they were files). When 1st tree
50 connect fails (e.g. due to signing negotiation failure) fix
51 leak that causes cifsd not to stop and rmmod to fail to cleanup
52 cifs_request_buffers pool. Fix problem with POSIX Open/Mkdir on
53 bigendian architectures. Fix possible memory corruption when
54 EAGAIN returned on kern_recvmsg. Return better error if server
55 requires packet signing but client has disabled it. When mounted
56 with cifsacl mount option - mode bits are approximated based
57 on the contents of the ACL of the file or directory. When cifs
58 mount helper is missing convert make sure that UNC name
59 has backslash (not forward slash) between ip address of server
64 Fix NTLMv2 signing. NFS server mounted over cifs works (if cifs mount is
65 done with "serverino" mount option). Add support for POSIX Unlink
66 (helps with certain sharing violation cases when server such as
67 Samba supports newer POSIX CIFS Protocol Extensions). Add "nounix"
68 mount option to allow disabling the CIFS Unix Extensions for just
69 that mount. Fix hang on spinlock in find_writable_file (race when
70 reopening file after session crash). Byte range unlock request to
71 windows server could unlock more bytes (on server copy of file)
72 than intended if start of unlock request is well before start of
73 a previous byte range lock that we issued.
77 IPv6 support. Enable ipv6 addresses to be passed on mount (put the ipv6
78 address after the "ip=" mount option, at least until mount.cifs is fixed to
79 handle DNS host to ipv6 name translation). Accept override of uid or gid
80 on mount even when Unix Extensions are negotiated (it used to be ignored
81 when Unix Extensions were ignored). This allows users to override the
82 default uid and gid for files when they are certain that the uids or
83 gids on the server do not match those of the client. Make "sec=none"
84 mount override username (so that null user connection is attempted)
85 to match what documentation said. Support for very large reads, over 127K,
86 available to some newer servers (such as Samba 3.0.26 and later but
87 note that it also requires setting CIFSMaxBufSize at module install
88 time to a larger value which may hurt performance in some cases).
89 Make sign option force signing (or fail if server does not support it).
93 Fix mtime bouncing around from local idea of last write times to remote time.
94 Fix hang (in i_size_read) when simultaneous size update of same remote file
95 on smp system corrupts sequence number. Do not reread unnecessarily partial page
96 (which we are about to overwrite anyway) when writing out file opened rw.
97 When DOS attribute of file on non-Unix server's file changes on the server side
98 from read-only back to read-write, reflect this change in default file mode
99 (we had been leaving a file's mode read-only until the inode were reloaded).
100 Allow setting of attribute back to ATTR_NORMAL (removing readonly dos attribute
101 when archive dos attribute not set and we are changing mode back to writeable
102 on server which does not support the Unix Extensions). Remove read only dos
103 attribute on chmod when adding any write permission (ie on any of
104 user/group/other (not all of user/group/other ie 0222) when
105 mounted to windows. Add support for POSIX MkDir (slight performance
106 enhancement and eliminates the network race between the mkdir and set
107 path info of the mode).
112 Fix oops in list_del during mount caused by unaligned string.
113 Fix file corruption which could occur on some large file
114 copies caused by writepages page i/o completion bug.
115 Seek to SEEK_END forces check for update of file size for non-cached
116 files. Allow file size to be updated on remote extend of locally open,
117 non-cached file. Fix reconnect to newer Samba servers (or other servers
118 which support the CIFS Unix/POSIX extensions) so that we again tell the
119 server the Unix/POSIX cifs capabilities which we support (SetFSInfo).
120 Add experimental support for new POSIX Open/Mkdir (which returns
121 stat information on the open, and allows setting the mode).
125 Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
126 Allow null user to be specified on mount ("username="). Do not return
127 EINVAL on readdir when filldir fails due to overwritten blocksize
128 (fixes FC problem). Return error in rename 2nd attempt retry (ie report
129 if rename by handle also fails, after rename by path fails, we were
130 not reporting whether the retry worked or not). Fix NTLMv2 to
131 work to Windows servers (mount with option "sec=ntlmv2").
135 Do not time out lockw calls when using posix extensions. Do not
136 time out requests if server still responding reasonably fast
137 on requests on other threads. Improve POSIX locking emulation,
138 (lock cancel now works, and unlock of merged range works even
139 to Windows servers now). Fix oops on mount to lanman servers
140 (win9x, os/2 etc.) when null password. Do not send listxattr
141 (SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
142 problem (instantiate inodes/dentries in right order for readdir).
146 Rewritten sessionsetup support, including support for legacy SMB
147 session setup needed for OS/2 and older servers such as Windows 95 and 98.
148 Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
149 so we can do search (ls etc.) to OS/2. Do not send NTCreateX
150 or recent levels of FindFirst unless server says it supports NT SMBs
151 (instead use legacy equivalents from LANMAN dialect). Fix to allow
152 NTLMv2 authentication support (now can use stronger password hashing
153 on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
154 Allow override of global cifs security flags on mount via "sec=" option(s).
158 POSIX locking to servers which support CIFS POSIX Extensions
159 (disabled by default controlled by proc/fs/cifs/Experimental).
160 Handle conversion of long share names (especially Asian languages)
161 to Unicode during mount. Fix memory leak in sess struct on reconnect.
162 Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
163 cifs open which helps rare case when setpathinfo fails or server does
168 Fix slow oplock break when mounted to different servers at the same time and
169 the tids match and we try to find matching fid on wrong server. Fix read
170 looping when signing required by server (2.6.16 kernel only). Fix readdir
171 vs. rename race which could cause each to hang. Return . and .. even
172 if server does not. Allow searches to skip first three entries and
173 begin at any location. Fix oops in find_writeable_file.
177 Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
178 configure stronger authentication. Fix sfu symlinks so they can
179 be followed (not just recognized). Fix wraparound of bcc on
180 read responses when buffer size over 64K and also fix wrap of
181 max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
182 cifs_user_read and cifs_readpages (when EAGAIN on send of smb
183 on socket is returned over and over). Add POSIX (advisory) byte range
184 locking support (requires server with newest CIFS UNIX Extensions
185 to the protocol implemented). Slow down negprot slightly in port 139
186 RFC1001 case to give session_init time on buggy servers.
190 Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
191 of readpages by eliminating one extra memcpy. Allow update of file size
192 from remote server even if file is open for write as long as mount is
193 directio. Recognize share mode security and send NTLM encrypted password
194 on tree connect if share mode negotiated.
198 Defer close of a file handle slightly if pending writes depend on that handle
199 (this reduces the EBADF bad file handle errors that can be logged under heavy
200 stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
201 Fix SFU style symlinks and mknod needed for servers which do not support the
202 CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
203 dentries so files that the client sees as deleted but that later get created
204 on the server will be recognized. Add client side permission check on setattr.
205 Timeout stuck requests better (where server has never responded or sent corrupt
210 Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
211 to be smaller at first (but increasing) so large write performance performance
212 over GigE is better. Do not hang thread on illegal byte range lock response
213 from Windows (Windows can send an RFC1001 size which does not match smb size) by
214 allowing an SMBs TCP length to be up to a few bytes longer than it should be.
215 wsize and rsize can now be larger than negotiated buffer size if server
216 supports large readx/writex, even when directio mount flag not specified.
217 Write size will in many cases now be 16K instead of 4K which greatly helps
218 file copy performance on lightly loaded networks. Fix oops in dnotify
219 when experimental config flag enabled. Make cifsFYI more granular.
223 Fix readdir caching when unlink removes file in current search buffer,
224 and this is followed by a rewind search to just before the deleted entry.
225 Do not attempt to set ctime unless atime and/or mtime change requested
226 (most servers throw it away anyway). Fix length check of received smbs
227 to be more accurate. Fix big endian problem with mapchars mount option,
228 and with a field returned by statfs.
232 Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
233 For these older servers, add option for passing netbios name of server in
234 on mount (servernetbiosname). Add suspend support for power management, to
235 avoid cifsd thread preventing software suspend from working.
236 Add mount option for disabling the default behavior of sending byte range lock
237 requests to the server (necessary for certain applications which break with
238 mandatory lock behavior such as Evolution), and also mount option for
239 requesting case insensitive matching for path based requests (requesting
240 case sensitive is the default).
244 Add writepage performance improvements. Fix path name conversions
245 for long filenames on mounts which were done with "mapchars" mount option
246 specified. Ensure multiplex ids do not collide. Fix case in which
247 rmmod can oops if done soon after last unmount. Fix truncated
248 search (readdir) output when resume filename was a long filename.
249 Fix filename conversion when mapchars mount option was specified and
250 filename was a long filename.
254 Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
255 Do not oops if root user kills cifs oplock kernel thread or
256 kills the cifsd thread (NB: killing the cifs kernel threads is not
257 recommended, unmount and rmmod cifs will kill them when they are
258 no longer needed). Fix readdir to ASCII servers (ie older servers
259 which do not support Unicode) and also require asterisk.
260 Fix out of memory case in which data could be written one page
261 off in the page cache.
265 Fix caching problem, in which readdir of directory containing a file
266 which was cached could cause the file's time stamp to be updated
267 without invalidating the readahead data (so we could get stale
268 file data on the client for that file even as the server copy changed).
269 Cleanup response processing so cifsd can not loop when abnormally
275 Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
276 transact response for an SMB request and search entry split across two frames.
277 Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
278 as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
279 unless server explicitly claims to support them in CIFS Unix extensions
280 POSIX ACL capability bit. Fix packet signing when multiuser mounting with
281 different users from the same client to the same server. Fix oops in
282 cifs_close. Add mount option for remapping reserved characters in
283 filenames (also allow recognizing files with created by SFU which have any
284 of these seven reserved characters, except backslash, to be recognized).
285 Fix invalid transact2 message (we were sometimes trying to interpret
286 oplock breaks as SMB responses). Add ioctl for checking that the
287 current uid matches the uid of the mounter (needed by umount.cifs).
288 Reduce the number of large buffer allocations in cifs response processing
289 (significantly reduces memory pressure under heavy stress with multiple
290 processes accessing the same server at the same time).
294 Fix updates of DOS attributes and time fields so that files on NT4 servers
295 do not get marked delete on close. Display sizes of cifs buffer pools in
296 cifs stats. Fix oops in unmount when cifsd thread being killed by
297 shutdown. Add generic readv/writev and aio support. Report inode numbers
298 consistently in readdir and lookup (when serverino mount option is
299 specified use the inode number that the server reports - for both lookup
300 and readdir, otherwise by default the locally generated inode number is used
301 for inodes created in either path since servers are not always able to
302 provide unique inode numbers when exporting multiple volumes from under one
307 Allow new nouser_xattr mount parm to disable xattr support for user namespace.
308 Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
309 (mostly affects NT4 servers) by retry with handle based network operation.
310 Add new POSIX Query FS Info for returning statfs info more accurately.
311 Handle passwords with multiple commas in them.
315 Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
316 Fix capabilities flags for large readx so as to allow reads larger than 64K.
320 Add module init parm for large SMB buffer size (to allow it to be changed
321 from its default of 16K) which is especially useful for large file copy
322 when mounting with the directio mount option. Fix oops after
323 returning from mount when experimental ExtendedSecurity enabled and
324 SpnegoNegotiated returning invalid error. Fix case to retry better when
325 peek returns from 1 to 3 bytes on socket which should have more data.
326 Fixed path based calls (such as cifs lookup) to handle path names
327 longer than 530 (now can handle PATH_MAX). Fix pass through authentication
328 from Samba server to DC (Samba required dummy LM password).
332 Turn off DNOTIFY (directory change notification support) by default
333 (unless built with the experimental flag) to fix hang with KDE
334 file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
335 waiting on an SMB response) in SendReceive when session dies but
336 reconnects quickly from another task. Add module init parms for
337 minimum number of large and small network buffers in the buffer pools,
338 and for the maximum number of simultaneous requests.
342 Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
343 and other POSIX CIFS compliant servers. Fix error mapping for getfacl
344 to EOPNOTSUPP when server does not support posix acls on the wire. Fix
345 improperly zeroed buffer in CIFS Unix extensions set times call.
349 Fix internationalization problem in cifs readdir with filenames that map to
350 longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
351 for readdir to netapp servers. Fix search rewind (seek into readdir to return
352 non-consecutive entries). Do not do readdir when server negotiates
353 buffer size to small to fit filename. Add support for reading POSIX ACLs from
354 the server (add also acl and noacl mount options).
358 Optionally allow using server side inode numbers, rather than client generated
359 ones by specifying mount option "serverino" - this is required for some apps
360 to work which double check hardlinked files and have persistent inode numbers.
364 Multiple bigendian fixes. On little endian systems (for reconnect after
365 network failure) fix tcp session reconnect code so we do not try first
366 to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
367 as directories rather than symlinks because we can do follow link on them.
371 Add config option to enable XATTR (extended attribute) support, mapping
372 xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
373 minor fixes pointed out by the Stanford SWAT checker (mostly missing
374 or out of order NULL pointer checks in little used error paths).
378 Add new mount parm to control whether mode check (generic_permission) is done
379 on the client. If Unix extensions are enabled and the uids on the client
380 and server do not match, client permission checks are meaningless on
381 server uids that do not exist on the client (this does not affect the
382 normal ACL check which occurs on the server). Fix default uid
383 on mknod to match create and mkdir. Add optional mount parm to allow
384 override of the default uid behavior (in which the server sets the uid
385 and gid of newly created files). Normally for network filesystem mounts
386 user want the server to set the uid/gid on newly created files (rather than
387 using uid of the client processes you would in a local filesystem).
391 Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
392 info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
393 (in build_wildcard_path_from_dentry). Fix mknod to pass type field
394 (block/char/fifo) properly. Remove spurious mount warning log entry when
395 credentials passed as mount argument. Set major/minor device number in
396 inode for block and char devices when unix extensions enabled.
400 Fix /proc/fs/cifs/Stats and DebugData display to handle larger
401 amounts of return data. Properly limit requests to MAX_REQ (50
402 is the usual maximum active multiplex SMB/CIFS requests per server).
403 Do not kill cifsd (and thus hurt the other SMB session) when more than one
404 session to the same server (but with different userids) exists and one
405 of the two user's smb sessions is being removed while leaving the other.
406 Do not loop reconnecting in cifsd demultiplex thread when admin
407 kills the thread without going through unmount.
411 Do not rename hardlinked files (since that should be a noop). Flush
412 cached write behind data when reopening a file after session abend,
413 except when already in write. Grab per socket sem during reconnect
414 to avoid oops in sendmsg if overlapping with reconnect. Do not
415 reset cached inode file size on readdir for files open for write on
421 Update number of blocks in file so du command is happier (in Linux a fake
422 blocksize of 512 is required for calculating number of blocks in inode).
423 Fix prepare write of partial pages to read in data from server if possible.
424 Fix race on tcpStatus field between unmount and reconnection code, causing
425 cifsd process sometimes to hang around forever. Improve out of memory
426 checks in cifs_filldir
430 Fix incorrect file size in file handle based setattr on big endian hardware.
431 Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
432 and closing file structs in writepage/partialpagewrite. Add statistics
433 for each mounted share (new menuconfig option). Fix endianness problem in
434 volume information displayed in /proc/fs/cifs/DebugData (only affects
435 affects big endian architectures). Prevent renames while constructing
436 path names for open, mkdir and rmdir.
440 Change to mempools for alloc smb request buffers and multiplex structs
441 to better handle low memory problems (and potential deadlocks).
445 Fix incomplete listings of large directories on Samba servers when Unix
446 extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
447 rename deadlock when writing out dirty pages at same time.
451 Fix open of files in which O_CREATE can cause the mode to change in
452 some cases. Fix case in which retry of write overlaps file close.
453 Fix PPC64 build error. Reduce excessive stack usage in smb password
454 hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
458 Fixes for large file copy, signal handling, socket retry, buffer
459 allocation and low memory situations.
463 Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
464 also now allowing support for specifying client netbiosname. NT4 support added.
468 Fix reconnection (and certain failed mounts) to properly wake up the
469 blocked users thread so it does not seem hung (in some cases was blocked
470 until the cifs receive timeout expired). Fix spurious error logging
471 to kernel log when application with open network files killed.
475 Fix /proc/fs module unload warning message (that could be logged
476 to the kernel log). Fix intermittent failure in connectathon
477 test7 (hardlink count not immediately refreshed in case in which
478 inode metadata can be incorrectly kept cached when time near zero)
482 Allow file_mode and dir_mode (specified at mount time) to be enforced
483 locally (the server already enforced its own ACLs too) for servers
484 that do not report the correct mode (do not support the
485 CIFS Unix Extensions).
489 Fix some small memory leaks in some unmount error paths. Fix major leak
490 of cache pages in readpages causing multiple read oriented stress
491 testcases (including fsx, and even large file copy) to fail over time.
495 Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
496 This allows files that differ only in case and improves performance of file
497 creation and file open to such servers. Fix semaphore conflict which causes
498 slow delete of open file to Samba (which unfortunately can cause an oplock
499 break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
503 fixes to cifs_readpages for fsx test case
507 Fix caching data integrity bug when extending file size especially when no
508 oplock on file. Fix spurious logging of valid already parsed mount options
509 that are parsed outside of the cifs vfs such as nosuid.
514 Connect to server when port number override not specified, and tcp port
515 unitialized. Reset search to restart at correct file when kernel routine
516 filldir returns error during large directory searches (readdir).
520 Fix caching problem when files opened by multiple clients in which
521 page cache could contain stale data, and write through did
522 not occur often enough while file was still open when read ahead
523 (read oplock) not allowed. Treat "sep=" when first mount option
524 as an override of comma as the default separator between mount
529 Allow passwords longer than 16 bytes. Allow null password string.
533 Gracefully clean up failed mounts when attempting to mount to servers such as
534 Windows 98 that terminate tcp sessions during protocol negotiation. Handle
535 embedded commas in mount parsing of passwords.
539 Invalidate local inode cached pages on oplock break and when last file
540 instance is closed so that the client does not continue using stale local
541 copy rather than later modified server copy of file. Do not reconnect
542 when server drops the tcp session prematurely before negotiate
543 protocol response. Fix oops in reopen_file when dentry freed. Allow
544 the support for CIFS Unix Extensions to be disabled via proc interface.
548 Fix hang in commit_write during reconnection of open files under heavy load.
549 Fix unload_nls oops in a mount failure path. Serialize writes to same socket
550 which also fixes any possible races when cifs signatures are enabled in SMBs
551 being sent out of signature sequence number order.
555 Fix byte range locking bug (endian problem) causing bad offset and
560 Fix oops (in send_sig) caused by CIFS unmount code trying to
561 wake up the demultiplex thread after it had exited. Do not log
562 error on harmless oplock release of closed handle.
566 Fix unsafe global variable usage and password hash failure on gcc 3.3.1
567 Fix problem reconnecting secondary mounts to same server after session
568 failure. Fix invalid dentry - race in mkdir when directory gets created
569 by another client between the lookup and mkdir.
573 Fix to list processing in reopen_files. Fix reconnection when server hung
574 but tcpip session still alive. Set proper timeout on socket read.
578 Add missing mount options including iocharset. SMP fixes in write and open.
579 Fix errors in reconnecting after TCP session failure. Fix module unloading
580 of default nls codepage
584 Active smb transactions should never go negative (fix double FreeXid). Fix
585 list processing in file routines. Check return code on kmalloc in open.
586 Fix spinlock usage for SMP.
590 Fix oops in reopen_files when invalid dentry. drop dentry on server rename
591 and on revalidate errors. Fix cases where pid is now tgid. Fix return code
592 on create hard link when server does not support them.
596 Fix scheduling while atomic error in getting inode info on newly created file.
597 Fix truncate of existing files opened with O_CREAT but not O_TRUNC set.
601 Fix oops on write to dead tcp session. Remove error log write for case when file open
602 O_CREAT but not O_EXCL
606 Fix non-POSIX behavior on rename of open file and delete of open file by taking
607 advantage of trans2 SetFileInfo rename facility if available on target server.
608 Retry on ENOSPC and EAGAIN socket errors.
612 Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix
613 allocation size miscalculation. After oplock token lost do not read through
618 Fix oops on empty file readahead. Fix for file size handling for locally cached files.
622 Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files
623 during auto reconnection to server after server recovered from failure.
627 Finish support for Linux 2.5 open/create changes, which removes the
628 redundant NTCreate/QPathInfo/close that was sent during file create.
629 Enable oplock by default. Enable packet signing by default (needed to
630 access many recent Windows servers)
634 Fix oops when mounting to long server names caused by inverted parms to kmalloc.
635 Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
636 we will choose a cifs user session (smb uid) that better matches the local
637 uid if a) the mount uid does not match the current uid and b) we have another
638 session to the same server (ip address) for a different mount which
639 matches the current local uid.
643 Add support for mknod of block or character devices. Fix oplock
644 code (distributed caching) to properly send response to oplock
649 Finish up CIFS packet digital signing for the default
650 NTLM security case. This should help Windows 2003
651 network interoperability since it is common for
652 packet signing to be required now. Fix statfs (stat -f)
653 which recently started returning errors due to
654 invalid value (-1 instead of 0) being set in the
655 struct kstatfs f_ffiles field.
659 Fix oops on stopping oplock thread when removing cifs when
664 Fix mount options for ro (readonly), uid, gid and file and directory mode.
668 Fix errors displayed on failed mounts to be more understandable.
669 Fixed various incorrect or misleading smb to posix error code mappings.
673 Fix display of NTFS DFS junctions to display as symlinks.
674 They are the network equivalent. Fix oops in
675 cifs_partialpagewrite caused by missing spinlock protection
676 of openfile linked list. Allow writebehind caching errors to
677 be returned to the application at file close.
681 Clean up options displayed in /proc/mounts by show_options to
682 be more consistent with other filesystems.
686 Fix delete of readonly file to Windows servers. Reflect
687 presence or absence of read only dos attribute in mode
688 bits for servers that do not support CIFS Unix extensions.
689 Fix shortened results on readdir of large directories to
690 servers supporting CIFS Unix extensions (caused by
691 incorrect resume key).
695 Fix truncate bug (set file size) that could cause hangs e.g. running fsx
699 unload nls if mount fails.
703 Add resume key support to search (readdir) code to workaround
704 Windows bug. Add /proc/fs/cifs/LookupCacheEnable which
705 allows disabling caching of attribute information for
710 Add more oplock handling (distributed caching code). Remove
711 dead code. Remove excessive stack space utilization from
716 Fix oops in get dfs referral (triggered when null path sent in to
717 mount). Add support for overriding rsize at mount time.
721 Fix buffer overrun in readdir which caused intermittent kernel oopses.
722 Fix writepage code to release kmap on write data. Allow "-ip=" new
723 mount option to be passed in on parameter distinct from the first part
724 (server name portion of) the UNC name. Allow override of the
725 tcp port of the target server via new mount option "-port="
729 Fix search handle leak on rewind. Fix setuid and gid so that they are
730 reflected in the local inode immediately. Cleanup of whitespace
731 to make 2.4 and 2.5 versions more consistent.
736 Fix signal sending so that captive thread (cifsd) exits on umount
737 (which was causing the warning in kmem_cache_free of the request buffers
738 at rmmod time). This had broken as a sideeffect of the recent global
739 kernel change to daemonize. Fix memory leak in readdir code which
740 showed up in "ls -R" (and applications that did search rewinding).
744 Reconnect tids and fids after session reconnection (still do not
745 reconnect byte range locks though). Fix problem caching
746 lookup information for directory inodes, improving performance,
747 especially in deep directory trees. Fix various build warnings.
751 Finish fixes to commit write for caching/readahead consistency. fsx
752 now works to Samba servers. Fix oops caused when readahead
753 was interrupted by a signal.
757 Fix data corruption (in partial page after truncate) that caused fsx to
758 fail to Windows servers. Cleaned up some extraneous error logging in
759 common error paths. Add generic sendfile support.
763 Fix memory leak in AllocMidQEntry.
764 Finish reconnection logic, so connection with server can be dropped
765 (or server rebooted) and the cifs client will reconnect.
769 Fix temporary socket leak when bad userid or password specified
770 (or other SMBSessSetup failure). Increase maximum buffer size to slightly
771 over 16K to allow negotiation of up to Samba and Windows server default read
772 sizes. Add support for readpages
776 Fix oops when username not passed in on mount. Extensive fixes and improvements
777 to error logging (strip redundant newlines, change debug macros to ensure newline
778 passed in and to be more consistent). Fix writepage wrong file handle problem,
779 a readonly file handle could be incorrectly used to attempt to write out
780 file updates through the page cache to multiply open files. This could cause
781 the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
782 shares to the same Windows server when using different usernames
783 (doing this to Samba servers worked but Windows was rejecting it) - now it is
784 possible to use different userids when connecting to the same server from a
785 Linux client. Fix oops when treeDisconnect called during unmount on
786 previously freed socket.
790 Fix oops in readpages caused by not setting address space operations in inode in
795 Includes support for deleting of open files and renaming over existing files (per POSIX
796 requirement). Add readlink support for Windows junction points (directory symlinks).
800 Changed read and write to go through pagecache. Added additional address space operations.
801 Memory mapped operations now working.
805 Added writepage code for additional memory mapping support. Fixed leak in xids causing
806 the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
807 every stat call. Additional formatting cleanup.
811 Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
815 Fixes from Zwane Mwaikambo for adding missing return code checking in a few places.
816 Also included a modified version of his fix to protect global list manipulation of
817 the smb session and tree connection and mid related global variables.
821 Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
822 changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
823 buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
827 More stylistic updates to better match kernel style. Add additional statistics
828 for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
829 and CIFS Packet Signing enablement.
833 Replace call to sleep_on with safer wait_on_event.
834 Make stylistic changes to better match kernel style recommendations.
835 Remove most typedef usage (except for the PDUs themselves).
839 Update mount so the -unc mount option is no longer required (the ip address can be specified
840 in a UNC style device name. Implementation of readpage/writepage started.
844 Fix intermittent problem with incorrect smb header checking on badly
845 fragmented tcp responses
849 Fixes to setting of allocation size and file size.
853 Various 2.5.38 fixes. Now works on 2.5.38
857 Prepare for 2.5 kernel merge. Remove ifdefs.
861 Socket buffer management fixes. Fix dual free.
865 Various big endian fixes for hardlinks and symlinks and also for dfs.
869 Various big endian fixes for servers with Unix extensions such as Samba
873 Various FindNext fixes for incorrect filenames on large directory searches on big endian
874 clients. basic posix file i/o tests now work on big endian machines, not just le
878 SessionSetup and NegotiateProtocol now work from Big Endian machines.
879 Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older
880 versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7).
884 Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
885 files now return the correct number of links on fstat as they are repeatedly linked and unlinked.
889 Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
890 session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
891 Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
892 (which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).
896 Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
897 it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
901 Rewrote much of connection and mount/unmount logic to handle bugs with
902 multiple uses to same share, multiple users to same server etc.
906 Fixed major problem with dentry corruption (missing call to dput)
910 Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
911 Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
912 although corresponding function not fully implemented in the vfs yet
916 Fixed dentry caching bug, misc. cleanup
920 Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
921 on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
922 Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
926 Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
927 and tested against Samba 2.2.5
932 1) Fixed lockrange to be correct (it was one byte too short)
934 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
935 show range as locked when there is a conflict with an existing lock.
937 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
938 in most cases. Eventually will offer optional ability to query server for the correct perms.
940 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
941 but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
944 4) Fixed error logging of valid mount options
946 5) Removed logging of password field.
948 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
949 and cleaned them up and made them more consistent with other cifs functions.
951 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
952 (with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
953 nor is the symlink support using the Unix extensions
955 8) Started adding the readlink and follow_link code
