3 POSIX locking to servers which support CIFS POSIX Extensions
4 (disabled by default controlled by proc/fs/cifs/Experimental).
5 Handle conversion of long share names (especially Asian languages)
6 to Unicode during mount.
10 Fix slow oplock break when mounted to different servers at the same time and
11 the tids match and we try to find matching fid on wrong server. Fix read
12 looping when signing required by server (2.6.16 kernel only). Fix readdir
13 vs. rename race which could cause each to hang. Return . and .. even
14 if server does not. Allow searches to skip first three entries and
15 begin at any location. Fix oops in find_writeable_file.
19 Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
20 configure stronger authentication. Fix sfu symlinks so they can
21 be followed (not just recognized). Fix wraparound of bcc on
22 read responses when buffer size over 64K and also fix wrap of
23 max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
24 cifs_user_read and cifs_readpages (when EAGAIN on send of smb
25 on socket is returned over and over). Add POSIX (advisory) byte range
26 locking support (requires server with newest CIFS UNIX Extensions
27 to the protocol implemented). Slow down negprot slightly in port 139
28 RFC1001 case to give session_init time on buggy servers.
32 Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
33 of readpages by eliminating one extra memcpy. Allow update of file size
34 from remote server even if file is open for write as long as mount is
35 directio. Recognize share mode security and send NTLM encrypted password
36 on tree connect if share mode negotiated.
40 Defer close of a file handle slightly if pending writes depend on that handle
41 (this reduces the EBADF bad file handle errors that can be logged under heavy
42 stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
43 Fix SFU style symlinks and mknod needed for servers which do not support the
44 CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
45 dentries so files that the client sees as deleted but that later get created
46 on the server will be recognized. Add client side permission check on setattr.
47 Timeout stuck requests better (where server has never responded or sent corrupt
52 Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
53 to be smaller at first (but increasing) so large write performance performance
54 over GigE is better. Do not hang thread on illegal byte range lock response
55 from Windows (Windows can send an RFC1001 size which does not match smb size) by
56 allowing an SMBs TCP length to be up to a few bytes longer than it should be.
57 wsize and rsize can now be larger than negotiated buffer size if server
58 supports large readx/writex, even when directio mount flag not specified.
59 Write size will in many cases now be 16K instead of 4K which greatly helps
60 file copy performance on lightly loaded networks. Fix oops in dnotify
61 when experimental config flag enabled. Make cifsFYI more granular.
65 Fix readdir caching when unlink removes file in current search buffer,
66 and this is followed by a rewind search to just before the deleted entry.
67 Do not attempt to set ctime unless atime and/or mtime change requested
68 (most servers throw it away anyway). Fix length check of received smbs
69 to be more accurate. Fix big endian problem with mapchars mount option,
70 and with a field returned by statfs.
74 Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
75 For these older servers, add option for passing netbios name of server in
76 on mount (servernetbiosname). Add suspend support for power management, to
77 avoid cifsd thread preventing software suspend from working.
78 Add mount option for disabling the default behavior of sending byte range lock
79 requests to the server (necessary for certain applications which break with
80 mandatory lock behavior such as Evolution), and also mount option for
81 requesting case insensitive matching for path based requests (requesting
82 case sensitive is the default).
86 Add writepage performance improvements. Fix path name conversions
87 for long filenames on mounts which were done with "mapchars" mount option
88 specified. Ensure multiplex ids do not collide. Fix case in which
89 rmmod can oops if done soon after last unmount. Fix truncated
90 search (readdir) output when resume filename was a long filename.
91 Fix filename conversion when mapchars mount option was specified and
92 filename was a long filename.
96 Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
97 Do not oops if root user kills cifs oplock kernel thread or
98 kills the cifsd thread (NB: killing the cifs kernel threads is not
99 recommended, unmount and rmmod cifs will kill them when they are
100 no longer needed). Fix readdir to ASCII servers (ie older servers
101 which do not support Unicode) and also require asterisk.
102 Fix out of memory case in which data could be written one page
103 off in the page cache.
107 Fix caching problem, in which readdir of directory containing a file
108 which was cached could cause the file's time stamp to be updated
109 without invalidating the readahead data (so we could get stale
110 file data on the client for that file even as the server copy changed).
111 Cleanup response processing so cifsd can not loop when abnormally
117 Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
118 transact response for an SMB request and search entry split across two frames.
119 Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
120 as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
121 unless server explicitly claims to support them in CIFS Unix extensions
122 POSIX ACL capability bit. Fix packet signing when multiuser mounting with
123 different users from the same client to the same server. Fix oops in
124 cifs_close. Add mount option for remapping reserved characters in
125 filenames (also allow recognizing files with created by SFU which have any
126 of these seven reserved characters, except backslash, to be recognized).
127 Fix invalid transact2 message (we were sometimes trying to interpret
128 oplock breaks as SMB responses). Add ioctl for checking that the
129 current uid matches the uid of the mounter (needed by umount.cifs).
130 Reduce the number of large buffer allocations in cifs response processing
131 (significantly reduces memory pressure under heavy stress with multiple
132 processes accessing the same server at the same time).
136 Fix updates of DOS attributes and time fields so that files on NT4 servers
137 do not get marked delete on close. Display sizes of cifs buffer pools in
138 cifs stats. Fix oops in unmount when cifsd thread being killed by
139 shutdown. Add generic readv/writev and aio support. Report inode numbers
140 consistently in readdir and lookup (when serverino mount option is
141 specified use the inode number that the server reports - for both lookup
142 and readdir, otherwise by default the locally generated inode number is used
143 for inodes created in either path since servers are not always able to
144 provide unique inode numbers when exporting multiple volumes from under one
149 Allow new nouser_xattr mount parm to disable xattr support for user namespace.
150 Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
151 (mostly affects NT4 servers) by retry with handle based network operation.
152 Add new POSIX Query FS Info for returning statfs info more accurately.
153 Handle passwords with multiple commas in them.
157 Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
158 Fix capabilities flags for large readx so as to allow reads larger than 64K.
162 Add module init parm for large SMB buffer size (to allow it to be changed
163 from its default of 16K) which is especially useful for large file copy
164 when mounting with the directio mount option. Fix oops after
165 returning from mount when experimental ExtendedSecurity enabled and
166 SpnegoNegotiated returning invalid error. Fix case to retry better when
167 peek returns from 1 to 3 bytes on socket which should have more data.
168 Fixed path based calls (such as cifs lookup) to handle path names
169 longer than 530 (now can handle PATH_MAX). Fix pass through authentication
170 from Samba server to DC (Samba required dummy LM password).
174 Turn off DNOTIFY (directory change notification support) by default
175 (unless built with the experimental flag) to fix hang with KDE
176 file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
177 waiting on an SMB response) in SendReceive when session dies but
178 reconnects quickly from another task. Add module init parms for
179 minimum number of large and small network buffers in the buffer pools,
180 and for the maximum number of simultaneous requests.
184 Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
185 and other POSIX CIFS compliant servers. Fix error mapping for getfacl
186 to EOPNOTSUPP when server does not support posix acls on the wire. Fix
187 improperly zeroed buffer in CIFS Unix extensions set times call.
191 Fix internationalization problem in cifs readdir with filenames that map to
192 longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
193 for readdir to netapp servers. Fix search rewind (seek into readdir to return
194 non-consecutive entries). Do not do readdir when server negotiates
195 buffer size to small to fit filename. Add support for reading POSIX ACLs from
196 the server (add also acl and noacl mount options).
200 Optionally allow using server side inode numbers, rather than client generated
201 ones by specifying mount option "serverino" - this is required for some apps
202 to work which double check hardlinked files and have persistent inode numbers.
206 Multiple bigendian fixes. On little endian systems (for reconnect after
207 network failure) fix tcp session reconnect code so we do not try first
208 to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
209 as directories rather than symlinks because we can do follow link on them.
213 Add config option to enable XATTR (extended attribute) support, mapping
214 xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
215 minor fixes pointed out by the Stanford SWAT checker (mostly missing
216 or out of order NULL pointer checks in little used error paths).
220 Add new mount parm to control whether mode check (generic_permission) is done
221 on the client. If Unix extensions are enabled and the uids on the client
222 and server do not match, client permission checks are meaningless on
223 server uids that do not exist on the client (this does not affect the
224 normal ACL check which occurs on the server). Fix default uid
225 on mknod to match create and mkdir. Add optional mount parm to allow
226 override of the default uid behavior (in which the server sets the uid
227 and gid of newly created files). Normally for network filesystem mounts
228 user want the server to set the uid/gid on newly created files (rather than
229 using uid of the client processes you would in a local filesystem).
233 Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
234 info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
235 (in build_wildcard_path_from_dentry). Fix mknod to pass type field
236 (block/char/fifo) properly. Remove spurious mount warning log entry when
237 credentials passed as mount argument. Set major/minor device number in
238 inode for block and char devices when unix extensions enabled.
242 Fix /proc/fs/cifs/Stats and DebugData display to handle larger
243 amounts of return data. Properly limit requests to MAX_REQ (50
244 is the usual maximum active multiplex SMB/CIFS requests per server).
245 Do not kill cifsd (and thus hurt the other SMB session) when more than one
246 session to the same server (but with different userids) exists and one
247 of the two user's smb sessions is being removed while leaving the other.
248 Do not loop reconnecting in cifsd demultiplex thread when admin
249 kills the thread without going through unmount.
253 Do not rename hardlinked files (since that should be a noop). Flush
254 cached write behind data when reopening a file after session abend,
255 except when already in write. Grab per socket sem during reconnect
256 to avoid oops in sendmsg if overlapping with reconnect. Do not
257 reset cached inode file size on readdir for files open for write on
263 Update number of blocks in file so du command is happier (in Linux a fake
264 blocksize of 512 is required for calculating number of blocks in inode).
265 Fix prepare write of partial pages to read in data from server if possible.
266 Fix race on tcpStatus field between unmount and reconnection code, causing
267 cifsd process sometimes to hang around forever. Improve out of memory
268 checks in cifs_filldir
272 Fix incorrect file size in file handle based setattr on big endian hardware.
273 Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
274 and closing file structs in writepage/partialpagewrite. Add statistics
275 for each mounted share (new menuconfig option). Fix endianness problem in
276 volume information displayed in /proc/fs/cifs/DebugData (only affects
277 affects big endian architectures). Prevent renames while constructing
278 path names for open, mkdir and rmdir.
282 Change to mempools for alloc smb request buffers and multiplex structs
283 to better handle low memory problems (and potential deadlocks).
287 Fix incomplete listings of large directories on Samba servers when Unix
288 extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
289 rename deadlock when writing out dirty pages at same time.
293 Fix open of files in which O_CREATE can cause the mode to change in
294 some cases. Fix case in which retry of write overlaps file close.
295 Fix PPC64 build error. Reduce excessive stack usage in smb password
296 hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
300 Fixes for large file copy, signal handling, socket retry, buffer
301 allocation and low memory situations.
305 Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
306 also now allowing support for specifying client netbiosname. NT4 support added.
310 Fix reconnection (and certain failed mounts) to properly wake up the
311 blocked users thread so it does not seem hung (in some cases was blocked
312 until the cifs receive timeout expired). Fix spurious error logging
313 to kernel log when application with open network files killed.
317 Fix /proc/fs module unload warning message (that could be logged
318 to the kernel log). Fix intermittent failure in connectathon
319 test7 (hardlink count not immediately refreshed in case in which
320 inode metadata can be incorrectly kept cached when time near zero)
324 Allow file_mode and dir_mode (specified at mount time) to be enforced
325 locally (the server already enforced its own ACLs too) for servers
326 that do not report the correct mode (do not support the
327 CIFS Unix Extensions).
331 Fix some small memory leaks in some unmount error paths. Fix major leak
332 of cache pages in readpages causing multiple read oriented stress
333 testcases (including fsx, and even large file copy) to fail over time.
337 Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
338 This allows files that differ only in case and improves performance of file
339 creation and file open to such servers. Fix semaphore conflict which causes
340 slow delete of open file to Samba (which unfortunately can cause an oplock
341 break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
345 fixes to cifs_readpages for fsx test case
349 Fix caching data integrity bug when extending file size especially when no
350 oplock on file. Fix spurious logging of valid already parsed mount options
351 that are parsed outside of the cifs vfs such as nosuid.
356 Connect to server when port number override not specified, and tcp port
357 unitialized. Reset search to restart at correct file when kernel routine
358 filldir returns error during large directory searches (readdir).
362 Fix caching problem when files opened by multiple clients in which
363 page cache could contain stale data, and write through did
364 not occur often enough while file was still open when read ahead
365 (read oplock) not allowed. Treat "sep=" when first mount option
366 as an override of comma as the default separator between mount
371 Allow passwords longer than 16 bytes. Allow null password string.
375 Gracefully clean up failed mounts when attempting to mount to servers such as
376 Windows 98 that terminate tcp sessions during protocol negotiation. Handle
377 embedded commas in mount parsing of passwords.
381 Invalidate local inode cached pages on oplock break and when last file
382 instance is closed so that the client does not continue using stale local
383 copy rather than later modified server copy of file. Do not reconnect
384 when server drops the tcp session prematurely before negotiate
385 protocol response. Fix oops in reopen_file when dentry freed. Allow
386 the support for CIFS Unix Extensions to be disabled via proc interface.
390 Fix hang in commit_write during reconnection of open files under heavy load.
391 Fix unload_nls oops in a mount failure path. Serialize writes to same socket
392 which also fixes any possible races when cifs signatures are enabled in SMBs
393 being sent out of signature sequence number order.
397 Fix byte range locking bug (endian problem) causing bad offset and
402 Fix oops (in send_sig) caused by CIFS unmount code trying to
403 wake up the demultiplex thread after it had exited. Do not log
404 error on harmless oplock release of closed handle.
408 Fix unsafe global variable usage and password hash failure on gcc 3.3.1
409 Fix problem reconnecting secondary mounts to same server after session
410 failure. Fix invalid dentry - race in mkdir when directory gets created
411 by another client between the lookup and mkdir.
415 Fix to list processing in reopen_files. Fix reconnection when server hung
416 but tcpip session still alive. Set proper timeout on socket read.
420 Add missing mount options including iocharset. SMP fixes in write and open.
421 Fix errors in reconnecting after TCP session failure. Fix module unloading
422 of default nls codepage
426 Active smb transactions should never go negative (fix double FreeXid). Fix
427 list processing in file routines. Check return code on kmalloc in open.
428 Fix spinlock usage for SMP.
432 Fix oops in reopen_files when invalid dentry. drop dentry on server rename
433 and on revalidate errors. Fix cases where pid is now tgid. Fix return code
434 on create hard link when server does not support them.
438 Fix scheduling while atomic error in getting inode info on newly created file.
439 Fix truncate of existing files opened with O_CREAT but not O_TRUNC set.
443 Fix oops on write to dead tcp session. Remove error log write for case when file open
444 O_CREAT but not O_EXCL
448 Fix non-POSIX behavior on rename of open file and delete of open file by taking
449 advantage of trans2 SetFileInfo rename facility if available on target server.
450 Retry on ENOSPC and EAGAIN socket errors.
454 Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix
455 allocation size miscalculation. After oplock token lost do not read through
460 Fix oops on empty file readahead. Fix for file size handling for locally cached files.
464 Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files
465 during auto reconnection to server after server recovered from failure.
469 Finish support for Linux 2.5 open/create changes, which removes the
470 redundant NTCreate/QPathInfo/close that was sent during file create.
471 Enable oplock by default. Enable packet signing by default (needed to
472 access many recent Windows servers)
476 Fix oops when mounting to long server names caused by inverted parms to kmalloc.
477 Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
478 we will choose a cifs user session (smb uid) that better matches the local
479 uid if a) the mount uid does not match the current uid and b) we have another
480 session to the same server (ip address) for a different mount which
481 matches the current local uid.
485 Add support for mknod of block or character devices. Fix oplock
486 code (distributed caching) to properly send response to oplock
491 Finish up CIFS packet digital signing for the default
492 NTLM security case. This should help Windows 2003
493 network interoperability since it is common for
494 packet signing to be required now. Fix statfs (stat -f)
495 which recently started returning errors due to
496 invalid value (-1 instead of 0) being set in the
497 struct kstatfs f_ffiles field.
501 Fix oops on stopping oplock thread when removing cifs when
506 Fix mount options for ro (readonly), uid, gid and file and directory mode.
510 Fix errors displayed on failed mounts to be more understandable.
511 Fixed various incorrect or misleading smb to posix error code mappings.
515 Fix display of NTFS DFS junctions to display as symlinks.
516 They are the network equivalent. Fix oops in
517 cifs_partialpagewrite caused by missing spinlock protection
518 of openfile linked list. Allow writebehind caching errors to
519 be returned to the application at file close.
523 Clean up options displayed in /proc/mounts by show_options to
524 be more consistent with other filesystems.
528 Fix delete of readonly file to Windows servers. Reflect
529 presence or absence of read only dos attribute in mode
530 bits for servers that do not support CIFS Unix extensions.
531 Fix shortened results on readdir of large directories to
532 servers supporting CIFS Unix extensions (caused by
533 incorrect resume key).
537 Fix truncate bug (set file size) that could cause hangs e.g. running fsx
541 unload nls if mount fails.
545 Add resume key support to search (readdir) code to workaround
546 Windows bug. Add /proc/fs/cifs/LookupCacheEnable which
547 allows disabling caching of attribute information for
552 Add more oplock handling (distributed caching code). Remove
553 dead code. Remove excessive stack space utilization from
558 Fix oops in get dfs referral (triggered when null path sent in to
559 mount). Add support for overriding rsize at mount time.
563 Fix buffer overrun in readdir which caused intermittent kernel oopses.
564 Fix writepage code to release kmap on write data. Allow "-ip=" new
565 mount option to be passed in on parameter distinct from the first part
566 (server name portion of) the UNC name. Allow override of the
567 tcp port of the target server via new mount option "-port="
571 Fix search handle leak on rewind. Fix setuid and gid so that they are
572 reflected in the local inode immediately. Cleanup of whitespace
573 to make 2.4 and 2.5 versions more consistent.
578 Fix signal sending so that captive thread (cifsd) exits on umount
579 (which was causing the warning in kmem_cache_free of the request buffers
580 at rmmod time). This had broken as a sideeffect of the recent global
581 kernel change to daemonize. Fix memory leak in readdir code which
582 showed up in "ls -R" (and applications that did search rewinding).
586 Reconnect tids and fids after session reconnection (still do not
587 reconnect byte range locks though). Fix problem caching
588 lookup information for directory inodes, improving performance,
589 especially in deep directory trees. Fix various build warnings.
593 Finish fixes to commit write for caching/readahead consistency. fsx
594 now works to Samba servers. Fix oops caused when readahead
595 was interrupted by a signal.
599 Fix data corruption (in partial page after truncate) that caused fsx to
600 fail to Windows servers. Cleaned up some extraneous error logging in
601 common error paths. Add generic sendfile support.
605 Fix memory leak in AllocMidQEntry.
606 Finish reconnection logic, so connection with server can be dropped
607 (or server rebooted) and the cifs client will reconnect.
611 Fix temporary socket leak when bad userid or password specified
612 (or other SMBSessSetup failure). Increase maximum buffer size to slightly
613 over 16K to allow negotiation of up to Samba and Windows server default read
614 sizes. Add support for readpages
618 Fix oops when username not passed in on mount. Extensive fixes and improvements
619 to error logging (strip redundant newlines, change debug macros to ensure newline
620 passed in and to be more consistent). Fix writepage wrong file handle problem,
621 a readonly file handle could be incorrectly used to attempt to write out
622 file updates through the page cache to multiply open files. This could cause
623 the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
624 shares to the same Windows server when using different usernames
625 (doing this to Samba servers worked but Windows was rejecting it) - now it is
626 possible to use different userids when connecting to the same server from a
627 Linux client. Fix oops when treeDisconnect called during unmount on
628 previously freed socket.
632 Fix oops in readpages caused by not setting address space operations in inode in
637 Includes support for deleting of open files and renaming over existing files (per POSIX
638 requirement). Add readlink support for Windows junction points (directory symlinks).
642 Changed read and write to go through pagecache. Added additional address space operations.
643 Memory mapped operations now working.
647 Added writepage code for additional memory mapping support. Fixed leak in xids causing
648 the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
649 every stat call. Additional formatting cleanup.
653 Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
657 Fixes from Zwane Mwaikambo for adding missing return code checking in a few places.
658 Also included a modified version of his fix to protect global list manipulation of
659 the smb session and tree connection and mid related global variables.
663 Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
664 changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
665 buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
669 More stylistic updates to better match kernel style. Add additional statistics
670 for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
671 and CIFS Packet Signing enablement.
675 Replace call to sleep_on with safer wait_on_event.
676 Make stylistic changes to better match kernel style recommendations.
677 Remove most typedef usage (except for the PDUs themselves).
681 Update mount so the -unc mount option is no longer required (the ip address can be specified
682 in a UNC style device name. Implementation of readpage/writepage started.
686 Fix intermittent problem with incorrect smb header checking on badly
687 fragmented tcp responses
691 Fixes to setting of allocation size and file size.
695 Various 2.5.38 fixes. Now works on 2.5.38
699 Prepare for 2.5 kernel merge. Remove ifdefs.
703 Socket buffer management fixes. Fix dual free.
707 Various big endian fixes for hardlinks and symlinks and also for dfs.
711 Various big endian fixes for servers with Unix extensions such as Samba
715 Various FindNext fixes for incorrect filenames on large directory searches on big endian
716 clients. basic posix file i/o tests now work on big endian machines, not just le
720 SessionSetup and NegotiateProtocol now work from Big Endian machines.
721 Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older
722 versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7).
726 Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
727 files now return the correct number of links on fstat as they are repeatedly linked and unlinked.
731 Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
732 session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
733 Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
734 (which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).
738 Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
739 it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
743 Rewrote much of connection and mount/unmount logic to handle bugs with
744 multiple uses to same share, multiple users to same server etc.
748 Fixed major problem with dentry corruption (missing call to dput)
752 Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
753 Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
754 although corresponding function not fully implemented in the vfs yet
758 Fixed dentry caching bug, misc. cleanup
762 Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
763 on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
764 Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
768 Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
769 and tested against Samba 2.2.5
774 1) Fixed lockrange to be correct (it was one byte too short)
776 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
777 show range as locked when there is a conflict with an existing lock.
779 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
780 in most cases. Eventually will offer optional ability to query server for the correct perms.
782 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
783 but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
786 4) Fixed error logging of valid mount options
788 5) Removed logging of password field.
790 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
791 and cleaned them up and made them more consistent with other cifs functions.
793 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
794 (with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
795 nor is the symlink support using the Unix extensions
797 8) Started adding the readlink and follow_link code
