3 Fix oops in list_del during mount caused by unaligned string.
4 Seek to SEEK_END forces check for update of file size for non-cached
9 Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
10 Allow null user to be specified on mount ("username="). Do not return
11 EINVAL on readdir when filldir fails due to overwritten blocksize
12 (fixes FC problem). Return error in rename 2nd attempt retry (ie report
13 if rename by handle also fails, after rename by path fails, we were
14 not reporting whether the retry worked or not). Fix NTLMv2 to
15 work to Windows servers (mount with option "sec=ntlmv2").
19 Do not time out lockw calls when using posix extensions. Do not
20 time out requests if server still responding reasonably fast
21 on requests on other threads. Improve POSIX locking emulation,
22 (lock cancel now works, and unlock of merged range works even
23 to Windows servers now). Fix oops on mount to lanman servers
24 (win9x, os/2 etc.) when null password. Do not send listxattr
25 (SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
26 problem (instantiate inodes/dentries in right order for readdir).
30 Rewritten sessionsetup support, including support for legacy SMB
31 session setup needed for OS/2 and older servers such as Windows 95 and 98.
32 Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
33 so we can do search (ls etc.) to OS/2. Do not send NTCreateX
34 or recent levels of FindFirst unless server says it supports NT SMBs
35 (instead use legacy equivalents from LANMAN dialect). Fix to allow
36 NTLMv2 authentication support (now can use stronger password hashing
37 on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
38 Allow override of global cifs security flags on mount via "sec=" option(s).
42 POSIX locking to servers which support CIFS POSIX Extensions
43 (disabled by default controlled by proc/fs/cifs/Experimental).
44 Handle conversion of long share names (especially Asian languages)
45 to Unicode during mount. Fix memory leak in sess struct on reconnect.
46 Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
47 cifs open which helps rare case when setpathinfo fails or server does
52 Fix slow oplock break when mounted to different servers at the same time and
53 the tids match and we try to find matching fid on wrong server. Fix read
54 looping when signing required by server (2.6.16 kernel only). Fix readdir
55 vs. rename race which could cause each to hang. Return . and .. even
56 if server does not. Allow searches to skip first three entries and
57 begin at any location. Fix oops in find_writeable_file.
61 Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
62 configure stronger authentication. Fix sfu symlinks so they can
63 be followed (not just recognized). Fix wraparound of bcc on
64 read responses when buffer size over 64K and also fix wrap of
65 max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
66 cifs_user_read and cifs_readpages (when EAGAIN on send of smb
67 on socket is returned over and over). Add POSIX (advisory) byte range
68 locking support (requires server with newest CIFS UNIX Extensions
69 to the protocol implemented). Slow down negprot slightly in port 139
70 RFC1001 case to give session_init time on buggy servers.
74 Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
75 of readpages by eliminating one extra memcpy. Allow update of file size
76 from remote server even if file is open for write as long as mount is
77 directio. Recognize share mode security and send NTLM encrypted password
78 on tree connect if share mode negotiated.
82 Defer close of a file handle slightly if pending writes depend on that handle
83 (this reduces the EBADF bad file handle errors that can be logged under heavy
84 stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
85 Fix SFU style symlinks and mknod needed for servers which do not support the
86 CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
87 dentries so files that the client sees as deleted but that later get created
88 on the server will be recognized. Add client side permission check on setattr.
89 Timeout stuck requests better (where server has never responded or sent corrupt
94 Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
95 to be smaller at first (but increasing) so large write performance performance
96 over GigE is better. Do not hang thread on illegal byte range lock response
97 from Windows (Windows can send an RFC1001 size which does not match smb size) by
98 allowing an SMBs TCP length to be up to a few bytes longer than it should be.
99 wsize and rsize can now be larger than negotiated buffer size if server
100 supports large readx/writex, even when directio mount flag not specified.
101 Write size will in many cases now be 16K instead of 4K which greatly helps
102 file copy performance on lightly loaded networks. Fix oops in dnotify
103 when experimental config flag enabled. Make cifsFYI more granular.
107 Fix readdir caching when unlink removes file in current search buffer,
108 and this is followed by a rewind search to just before the deleted entry.
109 Do not attempt to set ctime unless atime and/or mtime change requested
110 (most servers throw it away anyway). Fix length check of received smbs
111 to be more accurate. Fix big endian problem with mapchars mount option,
112 and with a field returned by statfs.
116 Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
117 For these older servers, add option for passing netbios name of server in
118 on mount (servernetbiosname). Add suspend support for power management, to
119 avoid cifsd thread preventing software suspend from working.
120 Add mount option for disabling the default behavior of sending byte range lock
121 requests to the server (necessary for certain applications which break with
122 mandatory lock behavior such as Evolution), and also mount option for
123 requesting case insensitive matching for path based requests (requesting
124 case sensitive is the default).
128 Add writepage performance improvements. Fix path name conversions
129 for long filenames on mounts which were done with "mapchars" mount option
130 specified. Ensure multiplex ids do not collide. Fix case in which
131 rmmod can oops if done soon after last unmount. Fix truncated
132 search (readdir) output when resume filename was a long filename.
133 Fix filename conversion when mapchars mount option was specified and
134 filename was a long filename.
138 Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
139 Do not oops if root user kills cifs oplock kernel thread or
140 kills the cifsd thread (NB: killing the cifs kernel threads is not
141 recommended, unmount and rmmod cifs will kill them when they are
142 no longer needed). Fix readdir to ASCII servers (ie older servers
143 which do not support Unicode) and also require asterisk.
144 Fix out of memory case in which data could be written one page
145 off in the page cache.
149 Fix caching problem, in which readdir of directory containing a file
150 which was cached could cause the file's time stamp to be updated
151 without invalidating the readahead data (so we could get stale
152 file data on the client for that file even as the server copy changed).
153 Cleanup response processing so cifsd can not loop when abnormally
159 Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
160 transact response for an SMB request and search entry split across two frames.
161 Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
162 as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
163 unless server explicitly claims to support them in CIFS Unix extensions
164 POSIX ACL capability bit. Fix packet signing when multiuser mounting with
165 different users from the same client to the same server. Fix oops in
166 cifs_close. Add mount option for remapping reserved characters in
167 filenames (also allow recognizing files with created by SFU which have any
168 of these seven reserved characters, except backslash, to be recognized).
169 Fix invalid transact2 message (we were sometimes trying to interpret
170 oplock breaks as SMB responses). Add ioctl for checking that the
171 current uid matches the uid of the mounter (needed by umount.cifs).
172 Reduce the number of large buffer allocations in cifs response processing
173 (significantly reduces memory pressure under heavy stress with multiple
174 processes accessing the same server at the same time).
178 Fix updates of DOS attributes and time fields so that files on NT4 servers
179 do not get marked delete on close. Display sizes of cifs buffer pools in
180 cifs stats. Fix oops in unmount when cifsd thread being killed by
181 shutdown. Add generic readv/writev and aio support. Report inode numbers
182 consistently in readdir and lookup (when serverino mount option is
183 specified use the inode number that the server reports - for both lookup
184 and readdir, otherwise by default the locally generated inode number is used
185 for inodes created in either path since servers are not always able to
186 provide unique inode numbers when exporting multiple volumes from under one
191 Allow new nouser_xattr mount parm to disable xattr support for user namespace.
192 Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
193 (mostly affects NT4 servers) by retry with handle based network operation.
194 Add new POSIX Query FS Info for returning statfs info more accurately.
195 Handle passwords with multiple commas in them.
199 Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
200 Fix capabilities flags for large readx so as to allow reads larger than 64K.
204 Add module init parm for large SMB buffer size (to allow it to be changed
205 from its default of 16K) which is especially useful for large file copy
206 when mounting with the directio mount option. Fix oops after
207 returning from mount when experimental ExtendedSecurity enabled and
208 SpnegoNegotiated returning invalid error. Fix case to retry better when
209 peek returns from 1 to 3 bytes on socket which should have more data.
210 Fixed path based calls (such as cifs lookup) to handle path names
211 longer than 530 (now can handle PATH_MAX). Fix pass through authentication
212 from Samba server to DC (Samba required dummy LM password).
216 Turn off DNOTIFY (directory change notification support) by default
217 (unless built with the experimental flag) to fix hang with KDE
218 file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
219 waiting on an SMB response) in SendReceive when session dies but
220 reconnects quickly from another task. Add module init parms for
221 minimum number of large and small network buffers in the buffer pools,
222 and for the maximum number of simultaneous requests.
226 Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
227 and other POSIX CIFS compliant servers. Fix error mapping for getfacl
228 to EOPNOTSUPP when server does not support posix acls on the wire. Fix
229 improperly zeroed buffer in CIFS Unix extensions set times call.
233 Fix internationalization problem in cifs readdir with filenames that map to
234 longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
235 for readdir to netapp servers. Fix search rewind (seek into readdir to return
236 non-consecutive entries). Do not do readdir when server negotiates
237 buffer size to small to fit filename. Add support for reading POSIX ACLs from
238 the server (add also acl and noacl mount options).
242 Optionally allow using server side inode numbers, rather than client generated
243 ones by specifying mount option "serverino" - this is required for some apps
244 to work which double check hardlinked files and have persistent inode numbers.
248 Multiple bigendian fixes. On little endian systems (for reconnect after
249 network failure) fix tcp session reconnect code so we do not try first
250 to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
251 as directories rather than symlinks because we can do follow link on them.
255 Add config option to enable XATTR (extended attribute) support, mapping
256 xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
257 minor fixes pointed out by the Stanford SWAT checker (mostly missing
258 or out of order NULL pointer checks in little used error paths).
262 Add new mount parm to control whether mode check (generic_permission) is done
263 on the client. If Unix extensions are enabled and the uids on the client
264 and server do not match, client permission checks are meaningless on
265 server uids that do not exist on the client (this does not affect the
266 normal ACL check which occurs on the server). Fix default uid
267 on mknod to match create and mkdir. Add optional mount parm to allow
268 override of the default uid behavior (in which the server sets the uid
269 and gid of newly created files). Normally for network filesystem mounts
270 user want the server to set the uid/gid on newly created files (rather than
271 using uid of the client processes you would in a local filesystem).
275 Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
276 info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
277 (in build_wildcard_path_from_dentry). Fix mknod to pass type field
278 (block/char/fifo) properly. Remove spurious mount warning log entry when
279 credentials passed as mount argument. Set major/minor device number in
280 inode for block and char devices when unix extensions enabled.
284 Fix /proc/fs/cifs/Stats and DebugData display to handle larger
285 amounts of return data. Properly limit requests to MAX_REQ (50
286 is the usual maximum active multiplex SMB/CIFS requests per server).
287 Do not kill cifsd (and thus hurt the other SMB session) when more than one
288 session to the same server (but with different userids) exists and one
289 of the two user's smb sessions is being removed while leaving the other.
290 Do not loop reconnecting in cifsd demultiplex thread when admin
291 kills the thread without going through unmount.
295 Do not rename hardlinked files (since that should be a noop). Flush
296 cached write behind data when reopening a file after session abend,
297 except when already in write. Grab per socket sem during reconnect
298 to avoid oops in sendmsg if overlapping with reconnect. Do not
299 reset cached inode file size on readdir for files open for write on
305 Update number of blocks in file so du command is happier (in Linux a fake
306 blocksize of 512 is required for calculating number of blocks in inode).
307 Fix prepare write of partial pages to read in data from server if possible.
308 Fix race on tcpStatus field between unmount and reconnection code, causing
309 cifsd process sometimes to hang around forever. Improve out of memory
310 checks in cifs_filldir
314 Fix incorrect file size in file handle based setattr on big endian hardware.
315 Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
316 and closing file structs in writepage/partialpagewrite. Add statistics
317 for each mounted share (new menuconfig option). Fix endianness problem in
318 volume information displayed in /proc/fs/cifs/DebugData (only affects
319 affects big endian architectures). Prevent renames while constructing
320 path names for open, mkdir and rmdir.
324 Change to mempools for alloc smb request buffers and multiplex structs
325 to better handle low memory problems (and potential deadlocks).
329 Fix incomplete listings of large directories on Samba servers when Unix
330 extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
331 rename deadlock when writing out dirty pages at same time.
335 Fix open of files in which O_CREATE can cause the mode to change in
336 some cases. Fix case in which retry of write overlaps file close.
337 Fix PPC64 build error. Reduce excessive stack usage in smb password
338 hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
342 Fixes for large file copy, signal handling, socket retry, buffer
343 allocation and low memory situations.
347 Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
348 also now allowing support for specifying client netbiosname. NT4 support added.
352 Fix reconnection (and certain failed mounts) to properly wake up the
353 blocked users thread so it does not seem hung (in some cases was blocked
354 until the cifs receive timeout expired). Fix spurious error logging
355 to kernel log when application with open network files killed.
359 Fix /proc/fs module unload warning message (that could be logged
360 to the kernel log). Fix intermittent failure in connectathon
361 test7 (hardlink count not immediately refreshed in case in which
362 inode metadata can be incorrectly kept cached when time near zero)
366 Allow file_mode and dir_mode (specified at mount time) to be enforced
367 locally (the server already enforced its own ACLs too) for servers
368 that do not report the correct mode (do not support the
369 CIFS Unix Extensions).
373 Fix some small memory leaks in some unmount error paths. Fix major leak
374 of cache pages in readpages causing multiple read oriented stress
375 testcases (including fsx, and even large file copy) to fail over time.
379 Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
380 This allows files that differ only in case and improves performance of file
381 creation and file open to such servers. Fix semaphore conflict which causes
382 slow delete of open file to Samba (which unfortunately can cause an oplock
383 break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
387 fixes to cifs_readpages for fsx test case
391 Fix caching data integrity bug when extending file size especially when no
392 oplock on file. Fix spurious logging of valid already parsed mount options
393 that are parsed outside of the cifs vfs such as nosuid.
398 Connect to server when port number override not specified, and tcp port
399 unitialized. Reset search to restart at correct file when kernel routine
400 filldir returns error during large directory searches (readdir).
404 Fix caching problem when files opened by multiple clients in which
405 page cache could contain stale data, and write through did
406 not occur often enough while file was still open when read ahead
407 (read oplock) not allowed. Treat "sep=" when first mount option
408 as an override of comma as the default separator between mount
413 Allow passwords longer than 16 bytes. Allow null password string.
417 Gracefully clean up failed mounts when attempting to mount to servers such as
418 Windows 98 that terminate tcp sessions during protocol negotiation. Handle
419 embedded commas in mount parsing of passwords.
423 Invalidate local inode cached pages on oplock break and when last file
424 instance is closed so that the client does not continue using stale local
425 copy rather than later modified server copy of file. Do not reconnect
426 when server drops the tcp session prematurely before negotiate
427 protocol response. Fix oops in reopen_file when dentry freed. Allow
428 the support for CIFS Unix Extensions to be disabled via proc interface.
432 Fix hang in commit_write during reconnection of open files under heavy load.
433 Fix unload_nls oops in a mount failure path. Serialize writes to same socket
434 which also fixes any possible races when cifs signatures are enabled in SMBs
435 being sent out of signature sequence number order.
439 Fix byte range locking bug (endian problem) causing bad offset and
444 Fix oops (in send_sig) caused by CIFS unmount code trying to
445 wake up the demultiplex thread after it had exited. Do not log
446 error on harmless oplock release of closed handle.
450 Fix unsafe global variable usage and password hash failure on gcc 3.3.1
451 Fix problem reconnecting secondary mounts to same server after session
452 failure. Fix invalid dentry - race in mkdir when directory gets created
453 by another client between the lookup and mkdir.
457 Fix to list processing in reopen_files. Fix reconnection when server hung
458 but tcpip session still alive. Set proper timeout on socket read.
462 Add missing mount options including iocharset. SMP fixes in write and open.
463 Fix errors in reconnecting after TCP session failure. Fix module unloading
464 of default nls codepage
468 Active smb transactions should never go negative (fix double FreeXid). Fix
469 list processing in file routines. Check return code on kmalloc in open.
470 Fix spinlock usage for SMP.
474 Fix oops in reopen_files when invalid dentry. drop dentry on server rename
475 and on revalidate errors. Fix cases where pid is now tgid. Fix return code
476 on create hard link when server does not support them.
480 Fix scheduling while atomic error in getting inode info on newly created file.
481 Fix truncate of existing files opened with O_CREAT but not O_TRUNC set.
485 Fix oops on write to dead tcp session. Remove error log write for case when file open
486 O_CREAT but not O_EXCL
490 Fix non-POSIX behavior on rename of open file and delete of open file by taking
491 advantage of trans2 SetFileInfo rename facility if available on target server.
492 Retry on ENOSPC and EAGAIN socket errors.
496 Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix
497 allocation size miscalculation. After oplock token lost do not read through
502 Fix oops on empty file readahead. Fix for file size handling for locally cached files.
506 Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files
507 during auto reconnection to server after server recovered from failure.
511 Finish support for Linux 2.5 open/create changes, which removes the
512 redundant NTCreate/QPathInfo/close that was sent during file create.
513 Enable oplock by default. Enable packet signing by default (needed to
514 access many recent Windows servers)
518 Fix oops when mounting to long server names caused by inverted parms to kmalloc.
519 Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
520 we will choose a cifs user session (smb uid) that better matches the local
521 uid if a) the mount uid does not match the current uid and b) we have another
522 session to the same server (ip address) for a different mount which
523 matches the current local uid.
527 Add support for mknod of block or character devices. Fix oplock
528 code (distributed caching) to properly send response to oplock
533 Finish up CIFS packet digital signing for the default
534 NTLM security case. This should help Windows 2003
535 network interoperability since it is common for
536 packet signing to be required now. Fix statfs (stat -f)
537 which recently started returning errors due to
538 invalid value (-1 instead of 0) being set in the
539 struct kstatfs f_ffiles field.
543 Fix oops on stopping oplock thread when removing cifs when
548 Fix mount options for ro (readonly), uid, gid and file and directory mode.
552 Fix errors displayed on failed mounts to be more understandable.
553 Fixed various incorrect or misleading smb to posix error code mappings.
557 Fix display of NTFS DFS junctions to display as symlinks.
558 They are the network equivalent. Fix oops in
559 cifs_partialpagewrite caused by missing spinlock protection
560 of openfile linked list. Allow writebehind caching errors to
561 be returned to the application at file close.
565 Clean up options displayed in /proc/mounts by show_options to
566 be more consistent with other filesystems.
570 Fix delete of readonly file to Windows servers. Reflect
571 presence or absence of read only dos attribute in mode
572 bits for servers that do not support CIFS Unix extensions.
573 Fix shortened results on readdir of large directories to
574 servers supporting CIFS Unix extensions (caused by
575 incorrect resume key).
579 Fix truncate bug (set file size) that could cause hangs e.g. running fsx
583 unload nls if mount fails.
587 Add resume key support to search (readdir) code to workaround
588 Windows bug. Add /proc/fs/cifs/LookupCacheEnable which
589 allows disabling caching of attribute information for
594 Add more oplock handling (distributed caching code). Remove
595 dead code. Remove excessive stack space utilization from
600 Fix oops in get dfs referral (triggered when null path sent in to
601 mount). Add support for overriding rsize at mount time.
605 Fix buffer overrun in readdir which caused intermittent kernel oopses.
606 Fix writepage code to release kmap on write data. Allow "-ip=" new
607 mount option to be passed in on parameter distinct from the first part
608 (server name portion of) the UNC name. Allow override of the
609 tcp port of the target server via new mount option "-port="
613 Fix search handle leak on rewind. Fix setuid and gid so that they are
614 reflected in the local inode immediately. Cleanup of whitespace
615 to make 2.4 and 2.5 versions more consistent.
620 Fix signal sending so that captive thread (cifsd) exits on umount
621 (which was causing the warning in kmem_cache_free of the request buffers
622 at rmmod time). This had broken as a sideeffect of the recent global
623 kernel change to daemonize. Fix memory leak in readdir code which
624 showed up in "ls -R" (and applications that did search rewinding).
628 Reconnect tids and fids after session reconnection (still do not
629 reconnect byte range locks though). Fix problem caching
630 lookup information for directory inodes, improving performance,
631 especially in deep directory trees. Fix various build warnings.
635 Finish fixes to commit write for caching/readahead consistency. fsx
636 now works to Samba servers. Fix oops caused when readahead
637 was interrupted by a signal.
641 Fix data corruption (in partial page after truncate) that caused fsx to
642 fail to Windows servers. Cleaned up some extraneous error logging in
643 common error paths. Add generic sendfile support.
647 Fix memory leak in AllocMidQEntry.
648 Finish reconnection logic, so connection with server can be dropped
649 (or server rebooted) and the cifs client will reconnect.
653 Fix temporary socket leak when bad userid or password specified
654 (or other SMBSessSetup failure). Increase maximum buffer size to slightly
655 over 16K to allow negotiation of up to Samba and Windows server default read
656 sizes. Add support for readpages
660 Fix oops when username not passed in on mount. Extensive fixes and improvements
661 to error logging (strip redundant newlines, change debug macros to ensure newline
662 passed in and to be more consistent). Fix writepage wrong file handle problem,
663 a readonly file handle could be incorrectly used to attempt to write out
664 file updates through the page cache to multiply open files. This could cause
665 the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
666 shares to the same Windows server when using different usernames
667 (doing this to Samba servers worked but Windows was rejecting it) - now it is
668 possible to use different userids when connecting to the same server from a
669 Linux client. Fix oops when treeDisconnect called during unmount on
670 previously freed socket.
674 Fix oops in readpages caused by not setting address space operations in inode in
679 Includes support for deleting of open files and renaming over existing files (per POSIX
680 requirement). Add readlink support for Windows junction points (directory symlinks).
684 Changed read and write to go through pagecache. Added additional address space operations.
685 Memory mapped operations now working.
689 Added writepage code for additional memory mapping support. Fixed leak in xids causing
690 the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
691 every stat call. Additional formatting cleanup.
695 Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
699 Fixes from Zwane Mwaikambo for adding missing return code checking in a few places.
700 Also included a modified version of his fix to protect global list manipulation of
701 the smb session and tree connection and mid related global variables.
705 Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
706 changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
707 buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
711 More stylistic updates to better match kernel style. Add additional statistics
712 for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
713 and CIFS Packet Signing enablement.
717 Replace call to sleep_on with safer wait_on_event.
718 Make stylistic changes to better match kernel style recommendations.
719 Remove most typedef usage (except for the PDUs themselves).
723 Update mount so the -unc mount option is no longer required (the ip address can be specified
724 in a UNC style device name. Implementation of readpage/writepage started.
728 Fix intermittent problem with incorrect smb header checking on badly
729 fragmented tcp responses
733 Fixes to setting of allocation size and file size.
737 Various 2.5.38 fixes. Now works on 2.5.38
741 Prepare for 2.5 kernel merge. Remove ifdefs.
745 Socket buffer management fixes. Fix dual free.
749 Various big endian fixes for hardlinks and symlinks and also for dfs.
753 Various big endian fixes for servers with Unix extensions such as Samba
757 Various FindNext fixes for incorrect filenames on large directory searches on big endian
758 clients. basic posix file i/o tests now work on big endian machines, not just le
762 SessionSetup and NegotiateProtocol now work from Big Endian machines.
763 Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older
764 versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7).
768 Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
769 files now return the correct number of links on fstat as they are repeatedly linked and unlinked.
773 Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
774 session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
775 Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
776 (which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).
780 Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
781 it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
785 Rewrote much of connection and mount/unmount logic to handle bugs with
786 multiple uses to same share, multiple users to same server etc.
790 Fixed major problem with dentry corruption (missing call to dput)
794 Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
795 Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
796 although corresponding function not fully implemented in the vfs yet
800 Fixed dentry caching bug, misc. cleanup
804 Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
805 on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
806 Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
810 Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
811 and tested against Samba 2.2.5
816 1) Fixed lockrange to be correct (it was one byte too short)
818 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
819 show range as locked when there is a conflict with an existing lock.
821 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
822 in most cases. Eventually will offer optional ability to query server for the correct perms.
824 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
825 but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
828 4) Fixed error logging of valid mount options
830 5) Removed logging of password field.
832 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
833 and cleaned them up and made them more consistent with other cifs functions.
835 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
836 (with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
837 nor is the symlink support using the Unix extensions
839 8) Started adding the readlink and follow_link code
