3 POSIX locking to servers which support CIFS POSIX Extensions
4 (disabled by default controlled by proc/fs/cifs/Experimental)
8 Fix slow oplock break when mounted to different servers at the same time and
9 the tids match and we try to find matching fid on wrong server. Fix read
10 looping when signing required by server (2.6.16 kernel only). Fix readdir
11 vs. rename race which could cause each to hang. Return . and .. even
12 if server does not. Allow searches to skip first three entries and
13 begin at any location. Fix oops in find_writeable_file.
17 Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
18 configure stronger authentication. Fix sfu symlinks so they can
19 be followed (not just recognized). Fix wraparound of bcc on
20 read responses when buffer size over 64K and also fix wrap of
21 max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
22 cifs_user_read and cifs_readpages (when EAGAIN on send of smb
23 on socket is returned over and over). Add POSIX (advisory) byte range
24 locking support (requires server with newest CIFS UNIX Extensions
25 to the protocol implemented). Slow down negprot slightly in port 139
26 RFC1001 case to give session_init time on buggy servers.
30 Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
31 of readpages by eliminating one extra memcpy. Allow update of file size
32 from remote server even if file is open for write as long as mount is
33 directio. Recognize share mode security and send NTLM encrypted password
34 on tree connect if share mode negotiated.
38 Defer close of a file handle slightly if pending writes depend on that handle
39 (this reduces the EBADF bad file handle errors that can be logged under heavy
40 stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
41 Fix SFU style symlinks and mknod needed for servers which do not support the
42 CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
43 dentries so files that the client sees as deleted but that later get created
44 on the server will be recognized. Add client side permission check on setattr.
45 Timeout stuck requests better (where server has never responded or sent corrupt
50 Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
51 to be smaller at first (but increasing) so large write performance performance
52 over GigE is better. Do not hang thread on illegal byte range lock response
53 from Windows (Windows can send an RFC1001 size which does not match smb size) by
54 allowing an SMBs TCP length to be up to a few bytes longer than it should be.
55 wsize and rsize can now be larger than negotiated buffer size if server
56 supports large readx/writex, even when directio mount flag not specified.
57 Write size will in many cases now be 16K instead of 4K which greatly helps
58 file copy performance on lightly loaded networks. Fix oops in dnotify
59 when experimental config flag enabled. Make cifsFYI more granular.
63 Fix readdir caching when unlink removes file in current search buffer,
64 and this is followed by a rewind search to just before the deleted entry.
65 Do not attempt to set ctime unless atime and/or mtime change requested
66 (most servers throw it away anyway). Fix length check of received smbs
67 to be more accurate. Fix big endian problem with mapchars mount option,
68 and with a field returned by statfs.
72 Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
73 For these older servers, add option for passing netbios name of server in
74 on mount (servernetbiosname). Add suspend support for power management, to
75 avoid cifsd thread preventing software suspend from working.
76 Add mount option for disabling the default behavior of sending byte range lock
77 requests to the server (necessary for certain applications which break with
78 mandatory lock behavior such as Evolution), and also mount option for
79 requesting case insensitive matching for path based requests (requesting
80 case sensitive is the default).
84 Add writepage performance improvements. Fix path name conversions
85 for long filenames on mounts which were done with "mapchars" mount option
86 specified. Ensure multiplex ids do not collide. Fix case in which
87 rmmod can oops if done soon after last unmount. Fix truncated
88 search (readdir) output when resume filename was a long filename.
89 Fix filename conversion when mapchars mount option was specified and
90 filename was a long filename.
94 Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
95 Do not oops if root user kills cifs oplock kernel thread or
96 kills the cifsd thread (NB: killing the cifs kernel threads is not
97 recommended, unmount and rmmod cifs will kill them when they are
98 no longer needed). Fix readdir to ASCII servers (ie older servers
99 which do not support Unicode) and also require asterisk.
100 Fix out of memory case in which data could be written one page
101 off in the page cache.
105 Fix caching problem, in which readdir of directory containing a file
106 which was cached could cause the file's time stamp to be updated
107 without invalidating the readahead data (so we could get stale
108 file data on the client for that file even as the server copy changed).
109 Cleanup response processing so cifsd can not loop when abnormally
115 Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
116 transact response for an SMB request and search entry split across two frames.
117 Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
118 as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
119 unless server explicitly claims to support them in CIFS Unix extensions
120 POSIX ACL capability bit. Fix packet signing when multiuser mounting with
121 different users from the same client to the same server. Fix oops in
122 cifs_close. Add mount option for remapping reserved characters in
123 filenames (also allow recognizing files with created by SFU which have any
124 of these seven reserved characters, except backslash, to be recognized).
125 Fix invalid transact2 message (we were sometimes trying to interpret
126 oplock breaks as SMB responses). Add ioctl for checking that the
127 current uid matches the uid of the mounter (needed by umount.cifs).
128 Reduce the number of large buffer allocations in cifs response processing
129 (significantly reduces memory pressure under heavy stress with multiple
130 processes accessing the same server at the same time).
134 Fix updates of DOS attributes and time fields so that files on NT4 servers
135 do not get marked delete on close. Display sizes of cifs buffer pools in
136 cifs stats. Fix oops in unmount when cifsd thread being killed by
137 shutdown. Add generic readv/writev and aio support. Report inode numbers
138 consistently in readdir and lookup (when serverino mount option is
139 specified use the inode number that the server reports - for both lookup
140 and readdir, otherwise by default the locally generated inode number is used
141 for inodes created in either path since servers are not always able to
142 provide unique inode numbers when exporting multiple volumes from under one
147 Allow new nouser_xattr mount parm to disable xattr support for user namespace.
148 Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
149 (mostly affects NT4 servers) by retry with handle based network operation.
150 Add new POSIX Query FS Info for returning statfs info more accurately.
151 Handle passwords with multiple commas in them.
155 Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
156 Fix capabilities flags for large readx so as to allow reads larger than 64K.
160 Add module init parm for large SMB buffer size (to allow it to be changed
161 from its default of 16K) which is especially useful for large file copy
162 when mounting with the directio mount option. Fix oops after
163 returning from mount when experimental ExtendedSecurity enabled and
164 SpnegoNegotiated returning invalid error. Fix case to retry better when
165 peek returns from 1 to 3 bytes on socket which should have more data.
166 Fixed path based calls (such as cifs lookup) to handle path names
167 longer than 530 (now can handle PATH_MAX). Fix pass through authentication
168 from Samba server to DC (Samba required dummy LM password).
172 Turn off DNOTIFY (directory change notification support) by default
173 (unless built with the experimental flag) to fix hang with KDE
174 file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
175 waiting on an SMB response) in SendReceive when session dies but
176 reconnects quickly from another task. Add module init parms for
177 minimum number of large and small network buffers in the buffer pools,
178 and for the maximum number of simultaneous requests.
182 Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
183 and other POSIX CIFS compliant servers. Fix error mapping for getfacl
184 to EOPNOTSUPP when server does not support posix acls on the wire. Fix
185 improperly zeroed buffer in CIFS Unix extensions set times call.
189 Fix internationalization problem in cifs readdir with filenames that map to
190 longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
191 for readdir to netapp servers. Fix search rewind (seek into readdir to return
192 non-consecutive entries). Do not do readdir when server negotiates
193 buffer size to small to fit filename. Add support for reading POSIX ACLs from
194 the server (add also acl and noacl mount options).
198 Optionally allow using server side inode numbers, rather than client generated
199 ones by specifying mount option "serverino" - this is required for some apps
200 to work which double check hardlinked files and have persistent inode numbers.
204 Multiple bigendian fixes. On little endian systems (for reconnect after
205 network failure) fix tcp session reconnect code so we do not try first
206 to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
207 as directories rather than symlinks because we can do follow link on them.
211 Add config option to enable XATTR (extended attribute) support, mapping
212 xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
213 minor fixes pointed out by the Stanford SWAT checker (mostly missing
214 or out of order NULL pointer checks in little used error paths).
218 Add new mount parm to control whether mode check (generic_permission) is done
219 on the client. If Unix extensions are enabled and the uids on the client
220 and server do not match, client permission checks are meaningless on
221 server uids that do not exist on the client (this does not affect the
222 normal ACL check which occurs on the server). Fix default uid
223 on mknod to match create and mkdir. Add optional mount parm to allow
224 override of the default uid behavior (in which the server sets the uid
225 and gid of newly created files). Normally for network filesystem mounts
226 user want the server to set the uid/gid on newly created files (rather than
227 using uid of the client processes you would in a local filesystem).
231 Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
232 info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
233 (in build_wildcard_path_from_dentry). Fix mknod to pass type field
234 (block/char/fifo) properly. Remove spurious mount warning log entry when
235 credentials passed as mount argument. Set major/minor device number in
236 inode for block and char devices when unix extensions enabled.
240 Fix /proc/fs/cifs/Stats and DebugData display to handle larger
241 amounts of return data. Properly limit requests to MAX_REQ (50
242 is the usual maximum active multiplex SMB/CIFS requests per server).
243 Do not kill cifsd (and thus hurt the other SMB session) when more than one
244 session to the same server (but with different userids) exists and one
245 of the two user's smb sessions is being removed while leaving the other.
246 Do not loop reconnecting in cifsd demultiplex thread when admin
247 kills the thread without going through unmount.
251 Do not rename hardlinked files (since that should be a noop). Flush
252 cached write behind data when reopening a file after session abend,
253 except when already in write. Grab per socket sem during reconnect
254 to avoid oops in sendmsg if overlapping with reconnect. Do not
255 reset cached inode file size on readdir for files open for write on
261 Update number of blocks in file so du command is happier (in Linux a fake
262 blocksize of 512 is required for calculating number of blocks in inode).
263 Fix prepare write of partial pages to read in data from server if possible.
264 Fix race on tcpStatus field between unmount and reconnection code, causing
265 cifsd process sometimes to hang around forever. Improve out of memory
266 checks in cifs_filldir
270 Fix incorrect file size in file handle based setattr on big endian hardware.
271 Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
272 and closing file structs in writepage/partialpagewrite. Add statistics
273 for each mounted share (new menuconfig option). Fix endianness problem in
274 volume information displayed in /proc/fs/cifs/DebugData (only affects
275 affects big endian architectures). Prevent renames while constructing
276 path names for open, mkdir and rmdir.
280 Change to mempools for alloc smb request buffers and multiplex structs
281 to better handle low memory problems (and potential deadlocks).
285 Fix incomplete listings of large directories on Samba servers when Unix
286 extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
287 rename deadlock when writing out dirty pages at same time.
291 Fix open of files in which O_CREATE can cause the mode to change in
292 some cases. Fix case in which retry of write overlaps file close.
293 Fix PPC64 build error. Reduce excessive stack usage in smb password
294 hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
298 Fixes for large file copy, signal handling, socket retry, buffer
299 allocation and low memory situations.
303 Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
304 also now allowing support for specifying client netbiosname. NT4 support added.
308 Fix reconnection (and certain failed mounts) to properly wake up the
309 blocked users thread so it does not seem hung (in some cases was blocked
310 until the cifs receive timeout expired). Fix spurious error logging
311 to kernel log when application with open network files killed.
315 Fix /proc/fs module unload warning message (that could be logged
316 to the kernel log). Fix intermittent failure in connectathon
317 test7 (hardlink count not immediately refreshed in case in which
318 inode metadata can be incorrectly kept cached when time near zero)
322 Allow file_mode and dir_mode (specified at mount time) to be enforced
323 locally (the server already enforced its own ACLs too) for servers
324 that do not report the correct mode (do not support the
325 CIFS Unix Extensions).
329 Fix some small memory leaks in some unmount error paths. Fix major leak
330 of cache pages in readpages causing multiple read oriented stress
331 testcases (including fsx, and even large file copy) to fail over time.
335 Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
336 This allows files that differ only in case and improves performance of file
337 creation and file open to such servers. Fix semaphore conflict which causes
338 slow delete of open file to Samba (which unfortunately can cause an oplock
339 break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
343 fixes to cifs_readpages for fsx test case
347 Fix caching data integrity bug when extending file size especially when no
348 oplock on file. Fix spurious logging of valid already parsed mount options
349 that are parsed outside of the cifs vfs such as nosuid.
354 Connect to server when port number override not specified, and tcp port
355 unitialized. Reset search to restart at correct file when kernel routine
356 filldir returns error during large directory searches (readdir).
360 Fix caching problem when files opened by multiple clients in which
361 page cache could contain stale data, and write through did
362 not occur often enough while file was still open when read ahead
363 (read oplock) not allowed. Treat "sep=" when first mount option
364 as an override of comma as the default separator between mount
369 Allow passwords longer than 16 bytes. Allow null password string.
373 Gracefully clean up failed mounts when attempting to mount to servers such as
374 Windows 98 that terminate tcp sessions during protocol negotiation. Handle
375 embedded commas in mount parsing of passwords.
379 Invalidate local inode cached pages on oplock break and when last file
380 instance is closed so that the client does not continue using stale local
381 copy rather than later modified server copy of file. Do not reconnect
382 when server drops the tcp session prematurely before negotiate
383 protocol response. Fix oops in reopen_file when dentry freed. Allow
384 the support for CIFS Unix Extensions to be disabled via proc interface.
388 Fix hang in commit_write during reconnection of open files under heavy load.
389 Fix unload_nls oops in a mount failure path. Serialize writes to same socket
390 which also fixes any possible races when cifs signatures are enabled in SMBs
391 being sent out of signature sequence number order.
395 Fix byte range locking bug (endian problem) causing bad offset and
400 Fix oops (in send_sig) caused by CIFS unmount code trying to
401 wake up the demultiplex thread after it had exited. Do not log
402 error on harmless oplock release of closed handle.
406 Fix unsafe global variable usage and password hash failure on gcc 3.3.1
407 Fix problem reconnecting secondary mounts to same server after session
408 failure. Fix invalid dentry - race in mkdir when directory gets created
409 by another client between the lookup and mkdir.
413 Fix to list processing in reopen_files. Fix reconnection when server hung
414 but tcpip session still alive. Set proper timeout on socket read.
418 Add missing mount options including iocharset. SMP fixes in write and open.
419 Fix errors in reconnecting after TCP session failure. Fix module unloading
420 of default nls codepage
424 Active smb transactions should never go negative (fix double FreeXid). Fix
425 list processing in file routines. Check return code on kmalloc in open.
426 Fix spinlock usage for SMP.
430 Fix oops in reopen_files when invalid dentry. drop dentry on server rename
431 and on revalidate errors. Fix cases where pid is now tgid. Fix return code
432 on create hard link when server does not support them.
436 Fix scheduling while atomic error in getting inode info on newly created file.
437 Fix truncate of existing files opened with O_CREAT but not O_TRUNC set.
441 Fix oops on write to dead tcp session. Remove error log write for case when file open
442 O_CREAT but not O_EXCL
446 Fix non-POSIX behavior on rename of open file and delete of open file by taking
447 advantage of trans2 SetFileInfo rename facility if available on target server.
448 Retry on ENOSPC and EAGAIN socket errors.
452 Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix
453 allocation size miscalculation. After oplock token lost do not read through
458 Fix oops on empty file readahead. Fix for file size handling for locally cached files.
462 Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files
463 during auto reconnection to server after server recovered from failure.
467 Finish support for Linux 2.5 open/create changes, which removes the
468 redundant NTCreate/QPathInfo/close that was sent during file create.
469 Enable oplock by default. Enable packet signing by default (needed to
470 access many recent Windows servers)
474 Fix oops when mounting to long server names caused by inverted parms to kmalloc.
475 Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
476 we will choose a cifs user session (smb uid) that better matches the local
477 uid if a) the mount uid does not match the current uid and b) we have another
478 session to the same server (ip address) for a different mount which
479 matches the current local uid.
483 Add support for mknod of block or character devices. Fix oplock
484 code (distributed caching) to properly send response to oplock
489 Finish up CIFS packet digital signing for the default
490 NTLM security case. This should help Windows 2003
491 network interoperability since it is common for
492 packet signing to be required now. Fix statfs (stat -f)
493 which recently started returning errors due to
494 invalid value (-1 instead of 0) being set in the
495 struct kstatfs f_ffiles field.
499 Fix oops on stopping oplock thread when removing cifs when
504 Fix mount options for ro (readonly), uid, gid and file and directory mode.
508 Fix errors displayed on failed mounts to be more understandable.
509 Fixed various incorrect or misleading smb to posix error code mappings.
513 Fix display of NTFS DFS junctions to display as symlinks.
514 They are the network equivalent. Fix oops in
515 cifs_partialpagewrite caused by missing spinlock protection
516 of openfile linked list. Allow writebehind caching errors to
517 be returned to the application at file close.
521 Clean up options displayed in /proc/mounts by show_options to
522 be more consistent with other filesystems.
526 Fix delete of readonly file to Windows servers. Reflect
527 presence or absence of read only dos attribute in mode
528 bits for servers that do not support CIFS Unix extensions.
529 Fix shortened results on readdir of large directories to
530 servers supporting CIFS Unix extensions (caused by
531 incorrect resume key).
535 Fix truncate bug (set file size) that could cause hangs e.g. running fsx
539 unload nls if mount fails.
543 Add resume key support to search (readdir) code to workaround
544 Windows bug. Add /proc/fs/cifs/LookupCacheEnable which
545 allows disabling caching of attribute information for
550 Add more oplock handling (distributed caching code). Remove
551 dead code. Remove excessive stack space utilization from
556 Fix oops in get dfs referral (triggered when null path sent in to
557 mount). Add support for overriding rsize at mount time.
561 Fix buffer overrun in readdir which caused intermittent kernel oopses.
562 Fix writepage code to release kmap on write data. Allow "-ip=" new
563 mount option to be passed in on parameter distinct from the first part
564 (server name portion of) the UNC name. Allow override of the
565 tcp port of the target server via new mount option "-port="
569 Fix search handle leak on rewind. Fix setuid and gid so that they are
570 reflected in the local inode immediately. Cleanup of whitespace
571 to make 2.4 and 2.5 versions more consistent.
576 Fix signal sending so that captive thread (cifsd) exits on umount
577 (which was causing the warning in kmem_cache_free of the request buffers
578 at rmmod time). This had broken as a sideeffect of the recent global
579 kernel change to daemonize. Fix memory leak in readdir code which
580 showed up in "ls -R" (and applications that did search rewinding).
584 Reconnect tids and fids after session reconnection (still do not
585 reconnect byte range locks though). Fix problem caching
586 lookup information for directory inodes, improving performance,
587 especially in deep directory trees. Fix various build warnings.
591 Finish fixes to commit write for caching/readahead consistency. fsx
592 now works to Samba servers. Fix oops caused when readahead
593 was interrupted by a signal.
597 Fix data corruption (in partial page after truncate) that caused fsx to
598 fail to Windows servers. Cleaned up some extraneous error logging in
599 common error paths. Add generic sendfile support.
603 Fix memory leak in AllocMidQEntry.
604 Finish reconnection logic, so connection with server can be dropped
605 (or server rebooted) and the cifs client will reconnect.
609 Fix temporary socket leak when bad userid or password specified
610 (or other SMBSessSetup failure). Increase maximum buffer size to slightly
611 over 16K to allow negotiation of up to Samba and Windows server default read
612 sizes. Add support for readpages
616 Fix oops when username not passed in on mount. Extensive fixes and improvements
617 to error logging (strip redundant newlines, change debug macros to ensure newline
618 passed in and to be more consistent). Fix writepage wrong file handle problem,
619 a readonly file handle could be incorrectly used to attempt to write out
620 file updates through the page cache to multiply open files. This could cause
621 the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
622 shares to the same Windows server when using different usernames
623 (doing this to Samba servers worked but Windows was rejecting it) - now it is
624 possible to use different userids when connecting to the same server from a
625 Linux client. Fix oops when treeDisconnect called during unmount on
626 previously freed socket.
630 Fix oops in readpages caused by not setting address space operations in inode in
635 Includes support for deleting of open files and renaming over existing files (per POSIX
636 requirement). Add readlink support for Windows junction points (directory symlinks).
640 Changed read and write to go through pagecache. Added additional address space operations.
641 Memory mapped operations now working.
645 Added writepage code for additional memory mapping support. Fixed leak in xids causing
646 the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
647 every stat call. Additional formatting cleanup.
651 Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
655 Fixes from Zwane Mwaikambo for adding missing return code checking in a few places.
656 Also included a modified version of his fix to protect global list manipulation of
657 the smb session and tree connection and mid related global variables.
661 Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
662 changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
663 buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
667 More stylistic updates to better match kernel style. Add additional statistics
668 for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
669 and CIFS Packet Signing enablement.
673 Replace call to sleep_on with safer wait_on_event.
674 Make stylistic changes to better match kernel style recommendations.
675 Remove most typedef usage (except for the PDUs themselves).
679 Update mount so the -unc mount option is no longer required (the ip address can be specified
680 in a UNC style device name. Implementation of readpage/writepage started.
684 Fix intermittent problem with incorrect smb header checking on badly
685 fragmented tcp responses
689 Fixes to setting of allocation size and file size.
693 Various 2.5.38 fixes. Now works on 2.5.38
697 Prepare for 2.5 kernel merge. Remove ifdefs.
701 Socket buffer management fixes. Fix dual free.
705 Various big endian fixes for hardlinks and symlinks and also for dfs.
709 Various big endian fixes for servers with Unix extensions such as Samba
713 Various FindNext fixes for incorrect filenames on large directory searches on big endian
714 clients. basic posix file i/o tests now work on big endian machines, not just le
718 SessionSetup and NegotiateProtocol now work from Big Endian machines.
719 Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older
720 versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7).
724 Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
725 files now return the correct number of links on fstat as they are repeatedly linked and unlinked.
729 Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
730 session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
731 Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
732 (which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).
736 Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
737 it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
741 Rewrote much of connection and mount/unmount logic to handle bugs with
742 multiple uses to same share, multiple users to same server etc.
746 Fixed major problem with dentry corruption (missing call to dput)
750 Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
751 Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
752 although corresponding function not fully implemented in the vfs yet
756 Fixed dentry caching bug, misc. cleanup
760 Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
761 on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
762 Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
766 Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
767 and tested against Samba 2.2.5
772 1) Fixed lockrange to be correct (it was one byte too short)
774 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
775 show range as locked when there is a conflict with an existing lock.
777 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
778 in most cases. Eventually will offer optional ability to query server for the correct perms.
780 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
781 but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
784 4) Fixed error logging of valid mount options
786 5) Removed logging of password field.
788 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
789 and cleaned them up and made them more consistent with other cifs functions.
791 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
792 (with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
793 nor is the symlink support using the Unix extensions
795 8) Started adding the readlink and follow_link code
