3 Fix oops in list_del during mount caused by unaligned string.
7 Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
8 Allow null user to be specified on mount ("username="). Do not return
9 EINVAL on readdir when filldir fails due to overwritten blocksize
10 (fixes FC problem). Return error in rename 2nd attempt retry (ie report
11 if rename by handle also fails, after rename by path fails, we were
12 not reporting whether the retry worked or not). Fix NTLMv2 to
13 work to Windows servers (mount with option "sec=ntlmv2").
17 Do not time out lockw calls when using posix extensions. Do not
18 time out requests if server still responding reasonably fast
19 on requests on other threads. Improve POSIX locking emulation,
20 (lock cancel now works, and unlock of merged range works even
21 to Windows servers now). Fix oops on mount to lanman servers
22 (win9x, os/2 etc.) when null password. Do not send listxattr
23 (SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
24 problem (instantiate inodes/dentries in right order for readdir).
28 Rewritten sessionsetup support, including support for legacy SMB
29 session setup needed for OS/2 and older servers such as Windows 95 and 98.
30 Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
31 so we can do search (ls etc.) to OS/2. Do not send NTCreateX
32 or recent levels of FindFirst unless server says it supports NT SMBs
33 (instead use legacy equivalents from LANMAN dialect). Fix to allow
34 NTLMv2 authentication support (now can use stronger password hashing
35 on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
36 Allow override of global cifs security flags on mount via "sec=" option(s).
40 POSIX locking to servers which support CIFS POSIX Extensions
41 (disabled by default controlled by proc/fs/cifs/Experimental).
42 Handle conversion of long share names (especially Asian languages)
43 to Unicode during mount. Fix memory leak in sess struct on reconnect.
44 Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
45 cifs open which helps rare case when setpathinfo fails or server does
50 Fix slow oplock break when mounted to different servers at the same time and
51 the tids match and we try to find matching fid on wrong server. Fix read
52 looping when signing required by server (2.6.16 kernel only). Fix readdir
53 vs. rename race which could cause each to hang. Return . and .. even
54 if server does not. Allow searches to skip first three entries and
55 begin at any location. Fix oops in find_writeable_file.
59 Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
60 configure stronger authentication. Fix sfu symlinks so they can
61 be followed (not just recognized). Fix wraparound of bcc on
62 read responses when buffer size over 64K and also fix wrap of
63 max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
64 cifs_user_read and cifs_readpages (when EAGAIN on send of smb
65 on socket is returned over and over). Add POSIX (advisory) byte range
66 locking support (requires server with newest CIFS UNIX Extensions
67 to the protocol implemented). Slow down negprot slightly in port 139
68 RFC1001 case to give session_init time on buggy servers.
72 Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
73 of readpages by eliminating one extra memcpy. Allow update of file size
74 from remote server even if file is open for write as long as mount is
75 directio. Recognize share mode security and send NTLM encrypted password
76 on tree connect if share mode negotiated.
80 Defer close of a file handle slightly if pending writes depend on that handle
81 (this reduces the EBADF bad file handle errors that can be logged under heavy
82 stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
83 Fix SFU style symlinks and mknod needed for servers which do not support the
84 CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
85 dentries so files that the client sees as deleted but that later get created
86 on the server will be recognized. Add client side permission check on setattr.
87 Timeout stuck requests better (where server has never responded or sent corrupt
92 Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
93 to be smaller at first (but increasing) so large write performance performance
94 over GigE is better. Do not hang thread on illegal byte range lock response
95 from Windows (Windows can send an RFC1001 size which does not match smb size) by
96 allowing an SMBs TCP length to be up to a few bytes longer than it should be.
97 wsize and rsize can now be larger than negotiated buffer size if server
98 supports large readx/writex, even when directio mount flag not specified.
99 Write size will in many cases now be 16K instead of 4K which greatly helps
100 file copy performance on lightly loaded networks. Fix oops in dnotify
101 when experimental config flag enabled. Make cifsFYI more granular.
105 Fix readdir caching when unlink removes file in current search buffer,
106 and this is followed by a rewind search to just before the deleted entry.
107 Do not attempt to set ctime unless atime and/or mtime change requested
108 (most servers throw it away anyway). Fix length check of received smbs
109 to be more accurate. Fix big endian problem with mapchars mount option,
110 and with a field returned by statfs.
114 Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
115 For these older servers, add option for passing netbios name of server in
116 on mount (servernetbiosname). Add suspend support for power management, to
117 avoid cifsd thread preventing software suspend from working.
118 Add mount option for disabling the default behavior of sending byte range lock
119 requests to the server (necessary for certain applications which break with
120 mandatory lock behavior such as Evolution), and also mount option for
121 requesting case insensitive matching for path based requests (requesting
122 case sensitive is the default).
126 Add writepage performance improvements. Fix path name conversions
127 for long filenames on mounts which were done with "mapchars" mount option
128 specified. Ensure multiplex ids do not collide. Fix case in which
129 rmmod can oops if done soon after last unmount. Fix truncated
130 search (readdir) output when resume filename was a long filename.
131 Fix filename conversion when mapchars mount option was specified and
132 filename was a long filename.
136 Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
137 Do not oops if root user kills cifs oplock kernel thread or
138 kills the cifsd thread (NB: killing the cifs kernel threads is not
139 recommended, unmount and rmmod cifs will kill them when they are
140 no longer needed). Fix readdir to ASCII servers (ie older servers
141 which do not support Unicode) and also require asterisk.
142 Fix out of memory case in which data could be written one page
143 off in the page cache.
147 Fix caching problem, in which readdir of directory containing a file
148 which was cached could cause the file's time stamp to be updated
149 without invalidating the readahead data (so we could get stale
150 file data on the client for that file even as the server copy changed).
151 Cleanup response processing so cifsd can not loop when abnormally
157 Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
158 transact response for an SMB request and search entry split across two frames.
159 Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
160 as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
161 unless server explicitly claims to support them in CIFS Unix extensions
162 POSIX ACL capability bit. Fix packet signing when multiuser mounting with
163 different users from the same client to the same server. Fix oops in
164 cifs_close. Add mount option for remapping reserved characters in
165 filenames (also allow recognizing files with created by SFU which have any
166 of these seven reserved characters, except backslash, to be recognized).
167 Fix invalid transact2 message (we were sometimes trying to interpret
168 oplock breaks as SMB responses). Add ioctl for checking that the
169 current uid matches the uid of the mounter (needed by umount.cifs).
170 Reduce the number of large buffer allocations in cifs response processing
171 (significantly reduces memory pressure under heavy stress with multiple
172 processes accessing the same server at the same time).
176 Fix updates of DOS attributes and time fields so that files on NT4 servers
177 do not get marked delete on close. Display sizes of cifs buffer pools in
178 cifs stats. Fix oops in unmount when cifsd thread being killed by
179 shutdown. Add generic readv/writev and aio support. Report inode numbers
180 consistently in readdir and lookup (when serverino mount option is
181 specified use the inode number that the server reports - for both lookup
182 and readdir, otherwise by default the locally generated inode number is used
183 for inodes created in either path since servers are not always able to
184 provide unique inode numbers when exporting multiple volumes from under one
189 Allow new nouser_xattr mount parm to disable xattr support for user namespace.
190 Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
191 (mostly affects NT4 servers) by retry with handle based network operation.
192 Add new POSIX Query FS Info for returning statfs info more accurately.
193 Handle passwords with multiple commas in them.
197 Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
198 Fix capabilities flags for large readx so as to allow reads larger than 64K.
202 Add module init parm for large SMB buffer size (to allow it to be changed
203 from its default of 16K) which is especially useful for large file copy
204 when mounting with the directio mount option. Fix oops after
205 returning from mount when experimental ExtendedSecurity enabled and
206 SpnegoNegotiated returning invalid error. Fix case to retry better when
207 peek returns from 1 to 3 bytes on socket which should have more data.
208 Fixed path based calls (such as cifs lookup) to handle path names
209 longer than 530 (now can handle PATH_MAX). Fix pass through authentication
210 from Samba server to DC (Samba required dummy LM password).
214 Turn off DNOTIFY (directory change notification support) by default
215 (unless built with the experimental flag) to fix hang with KDE
216 file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
217 waiting on an SMB response) in SendReceive when session dies but
218 reconnects quickly from another task. Add module init parms for
219 minimum number of large and small network buffers in the buffer pools,
220 and for the maximum number of simultaneous requests.
224 Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
225 and other POSIX CIFS compliant servers. Fix error mapping for getfacl
226 to EOPNOTSUPP when server does not support posix acls on the wire. Fix
227 improperly zeroed buffer in CIFS Unix extensions set times call.
231 Fix internationalization problem in cifs readdir with filenames that map to
232 longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
233 for readdir to netapp servers. Fix search rewind (seek into readdir to return
234 non-consecutive entries). Do not do readdir when server negotiates
235 buffer size to small to fit filename. Add support for reading POSIX ACLs from
236 the server (add also acl and noacl mount options).
240 Optionally allow using server side inode numbers, rather than client generated
241 ones by specifying mount option "serverino" - this is required for some apps
242 to work which double check hardlinked files and have persistent inode numbers.
246 Multiple bigendian fixes. On little endian systems (for reconnect after
247 network failure) fix tcp session reconnect code so we do not try first
248 to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
249 as directories rather than symlinks because we can do follow link on them.
253 Add config option to enable XATTR (extended attribute) support, mapping
254 xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
255 minor fixes pointed out by the Stanford SWAT checker (mostly missing
256 or out of order NULL pointer checks in little used error paths).
260 Add new mount parm to control whether mode check (generic_permission) is done
261 on the client. If Unix extensions are enabled and the uids on the client
262 and server do not match, client permission checks are meaningless on
263 server uids that do not exist on the client (this does not affect the
264 normal ACL check which occurs on the server). Fix default uid
265 on mknod to match create and mkdir. Add optional mount parm to allow
266 override of the default uid behavior (in which the server sets the uid
267 and gid of newly created files). Normally for network filesystem mounts
268 user want the server to set the uid/gid on newly created files (rather than
269 using uid of the client processes you would in a local filesystem).
273 Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
274 info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
275 (in build_wildcard_path_from_dentry). Fix mknod to pass type field
276 (block/char/fifo) properly. Remove spurious mount warning log entry when
277 credentials passed as mount argument. Set major/minor device number in
278 inode for block and char devices when unix extensions enabled.
282 Fix /proc/fs/cifs/Stats and DebugData display to handle larger
283 amounts of return data. Properly limit requests to MAX_REQ (50
284 is the usual maximum active multiplex SMB/CIFS requests per server).
285 Do not kill cifsd (and thus hurt the other SMB session) when more than one
286 session to the same server (but with different userids) exists and one
287 of the two user's smb sessions is being removed while leaving the other.
288 Do not loop reconnecting in cifsd demultiplex thread when admin
289 kills the thread without going through unmount.
293 Do not rename hardlinked files (since that should be a noop). Flush
294 cached write behind data when reopening a file after session abend,
295 except when already in write. Grab per socket sem during reconnect
296 to avoid oops in sendmsg if overlapping with reconnect. Do not
297 reset cached inode file size on readdir for files open for write on
303 Update number of blocks in file so du command is happier (in Linux a fake
304 blocksize of 512 is required for calculating number of blocks in inode).
305 Fix prepare write of partial pages to read in data from server if possible.
306 Fix race on tcpStatus field between unmount and reconnection code, causing
307 cifsd process sometimes to hang around forever. Improve out of memory
308 checks in cifs_filldir
312 Fix incorrect file size in file handle based setattr on big endian hardware.
313 Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
314 and closing file structs in writepage/partialpagewrite. Add statistics
315 for each mounted share (new menuconfig option). Fix endianness problem in
316 volume information displayed in /proc/fs/cifs/DebugData (only affects
317 affects big endian architectures). Prevent renames while constructing
318 path names for open, mkdir and rmdir.
322 Change to mempools for alloc smb request buffers and multiplex structs
323 to better handle low memory problems (and potential deadlocks).
327 Fix incomplete listings of large directories on Samba servers when Unix
328 extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
329 rename deadlock when writing out dirty pages at same time.
333 Fix open of files in which O_CREATE can cause the mode to change in
334 some cases. Fix case in which retry of write overlaps file close.
335 Fix PPC64 build error. Reduce excessive stack usage in smb password
336 hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
340 Fixes for large file copy, signal handling, socket retry, buffer
341 allocation and low memory situations.
345 Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
346 also now allowing support for specifying client netbiosname. NT4 support added.
350 Fix reconnection (and certain failed mounts) to properly wake up the
351 blocked users thread so it does not seem hung (in some cases was blocked
352 until the cifs receive timeout expired). Fix spurious error logging
353 to kernel log when application with open network files killed.
357 Fix /proc/fs module unload warning message (that could be logged
358 to the kernel log). Fix intermittent failure in connectathon
359 test7 (hardlink count not immediately refreshed in case in which
360 inode metadata can be incorrectly kept cached when time near zero)
364 Allow file_mode and dir_mode (specified at mount time) to be enforced
365 locally (the server already enforced its own ACLs too) for servers
366 that do not report the correct mode (do not support the
367 CIFS Unix Extensions).
371 Fix some small memory leaks in some unmount error paths. Fix major leak
372 of cache pages in readpages causing multiple read oriented stress
373 testcases (including fsx, and even large file copy) to fail over time.
377 Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
378 This allows files that differ only in case and improves performance of file
379 creation and file open to such servers. Fix semaphore conflict which causes
380 slow delete of open file to Samba (which unfortunately can cause an oplock
381 break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
385 fixes to cifs_readpages for fsx test case
389 Fix caching data integrity bug when extending file size especially when no
390 oplock on file. Fix spurious logging of valid already parsed mount options
391 that are parsed outside of the cifs vfs such as nosuid.
396 Connect to server when port number override not specified, and tcp port
397 unitialized. Reset search to restart at correct file when kernel routine
398 filldir returns error during large directory searches (readdir).
402 Fix caching problem when files opened by multiple clients in which
403 page cache could contain stale data, and write through did
404 not occur often enough while file was still open when read ahead
405 (read oplock) not allowed. Treat "sep=" when first mount option
406 as an override of comma as the default separator between mount
411 Allow passwords longer than 16 bytes. Allow null password string.
415 Gracefully clean up failed mounts when attempting to mount to servers such as
416 Windows 98 that terminate tcp sessions during protocol negotiation. Handle
417 embedded commas in mount parsing of passwords.
421 Invalidate local inode cached pages on oplock break and when last file
422 instance is closed so that the client does not continue using stale local
423 copy rather than later modified server copy of file. Do not reconnect
424 when server drops the tcp session prematurely before negotiate
425 protocol response. Fix oops in reopen_file when dentry freed. Allow
426 the support for CIFS Unix Extensions to be disabled via proc interface.
430 Fix hang in commit_write during reconnection of open files under heavy load.
431 Fix unload_nls oops in a mount failure path. Serialize writes to same socket
432 which also fixes any possible races when cifs signatures are enabled in SMBs
433 being sent out of signature sequence number order.
437 Fix byte range locking bug (endian problem) causing bad offset and
442 Fix oops (in send_sig) caused by CIFS unmount code trying to
443 wake up the demultiplex thread after it had exited. Do not log
444 error on harmless oplock release of closed handle.
448 Fix unsafe global variable usage and password hash failure on gcc 3.3.1
449 Fix problem reconnecting secondary mounts to same server after session
450 failure. Fix invalid dentry - race in mkdir when directory gets created
451 by another client between the lookup and mkdir.
455 Fix to list processing in reopen_files. Fix reconnection when server hung
456 but tcpip session still alive. Set proper timeout on socket read.
460 Add missing mount options including iocharset. SMP fixes in write and open.
461 Fix errors in reconnecting after TCP session failure. Fix module unloading
462 of default nls codepage
466 Active smb transactions should never go negative (fix double FreeXid). Fix
467 list processing in file routines. Check return code on kmalloc in open.
468 Fix spinlock usage for SMP.
472 Fix oops in reopen_files when invalid dentry. drop dentry on server rename
473 and on revalidate errors. Fix cases where pid is now tgid. Fix return code
474 on create hard link when server does not support them.
478 Fix scheduling while atomic error in getting inode info on newly created file.
479 Fix truncate of existing files opened with O_CREAT but not O_TRUNC set.
483 Fix oops on write to dead tcp session. Remove error log write for case when file open
484 O_CREAT but not O_EXCL
488 Fix non-POSIX behavior on rename of open file and delete of open file by taking
489 advantage of trans2 SetFileInfo rename facility if available on target server.
490 Retry on ENOSPC and EAGAIN socket errors.
494 Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix
495 allocation size miscalculation. After oplock token lost do not read through
500 Fix oops on empty file readahead. Fix for file size handling for locally cached files.
504 Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files
505 during auto reconnection to server after server recovered from failure.
509 Finish support for Linux 2.5 open/create changes, which removes the
510 redundant NTCreate/QPathInfo/close that was sent during file create.
511 Enable oplock by default. Enable packet signing by default (needed to
512 access many recent Windows servers)
516 Fix oops when mounting to long server names caused by inverted parms to kmalloc.
517 Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
518 we will choose a cifs user session (smb uid) that better matches the local
519 uid if a) the mount uid does not match the current uid and b) we have another
520 session to the same server (ip address) for a different mount which
521 matches the current local uid.
525 Add support for mknod of block or character devices. Fix oplock
526 code (distributed caching) to properly send response to oplock
531 Finish up CIFS packet digital signing for the default
532 NTLM security case. This should help Windows 2003
533 network interoperability since it is common for
534 packet signing to be required now. Fix statfs (stat -f)
535 which recently started returning errors due to
536 invalid value (-1 instead of 0) being set in the
537 struct kstatfs f_ffiles field.
541 Fix oops on stopping oplock thread when removing cifs when
546 Fix mount options for ro (readonly), uid, gid and file and directory mode.
550 Fix errors displayed on failed mounts to be more understandable.
551 Fixed various incorrect or misleading smb to posix error code mappings.
555 Fix display of NTFS DFS junctions to display as symlinks.
556 They are the network equivalent. Fix oops in
557 cifs_partialpagewrite caused by missing spinlock protection
558 of openfile linked list. Allow writebehind caching errors to
559 be returned to the application at file close.
563 Clean up options displayed in /proc/mounts by show_options to
564 be more consistent with other filesystems.
568 Fix delete of readonly file to Windows servers. Reflect
569 presence or absence of read only dos attribute in mode
570 bits for servers that do not support CIFS Unix extensions.
571 Fix shortened results on readdir of large directories to
572 servers supporting CIFS Unix extensions (caused by
573 incorrect resume key).
577 Fix truncate bug (set file size) that could cause hangs e.g. running fsx
581 unload nls if mount fails.
585 Add resume key support to search (readdir) code to workaround
586 Windows bug. Add /proc/fs/cifs/LookupCacheEnable which
587 allows disabling caching of attribute information for
592 Add more oplock handling (distributed caching code). Remove
593 dead code. Remove excessive stack space utilization from
598 Fix oops in get dfs referral (triggered when null path sent in to
599 mount). Add support for overriding rsize at mount time.
603 Fix buffer overrun in readdir which caused intermittent kernel oopses.
604 Fix writepage code to release kmap on write data. Allow "-ip=" new
605 mount option to be passed in on parameter distinct from the first part
606 (server name portion of) the UNC name. Allow override of the
607 tcp port of the target server via new mount option "-port="
611 Fix search handle leak on rewind. Fix setuid and gid so that they are
612 reflected in the local inode immediately. Cleanup of whitespace
613 to make 2.4 and 2.5 versions more consistent.
618 Fix signal sending so that captive thread (cifsd) exits on umount
619 (which was causing the warning in kmem_cache_free of the request buffers
620 at rmmod time). This had broken as a sideeffect of the recent global
621 kernel change to daemonize. Fix memory leak in readdir code which
622 showed up in "ls -R" (and applications that did search rewinding).
626 Reconnect tids and fids after session reconnection (still do not
627 reconnect byte range locks though). Fix problem caching
628 lookup information for directory inodes, improving performance,
629 especially in deep directory trees. Fix various build warnings.
633 Finish fixes to commit write for caching/readahead consistency. fsx
634 now works to Samba servers. Fix oops caused when readahead
635 was interrupted by a signal.
639 Fix data corruption (in partial page after truncate) that caused fsx to
640 fail to Windows servers. Cleaned up some extraneous error logging in
641 common error paths. Add generic sendfile support.
645 Fix memory leak in AllocMidQEntry.
646 Finish reconnection logic, so connection with server can be dropped
647 (or server rebooted) and the cifs client will reconnect.
651 Fix temporary socket leak when bad userid or password specified
652 (or other SMBSessSetup failure). Increase maximum buffer size to slightly
653 over 16K to allow negotiation of up to Samba and Windows server default read
654 sizes. Add support for readpages
658 Fix oops when username not passed in on mount. Extensive fixes and improvements
659 to error logging (strip redundant newlines, change debug macros to ensure newline
660 passed in and to be more consistent). Fix writepage wrong file handle problem,
661 a readonly file handle could be incorrectly used to attempt to write out
662 file updates through the page cache to multiply open files. This could cause
663 the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
664 shares to the same Windows server when using different usernames
665 (doing this to Samba servers worked but Windows was rejecting it) - now it is
666 possible to use different userids when connecting to the same server from a
667 Linux client. Fix oops when treeDisconnect called during unmount on
668 previously freed socket.
672 Fix oops in readpages caused by not setting address space operations in inode in
677 Includes support for deleting of open files and renaming over existing files (per POSIX
678 requirement). Add readlink support for Windows junction points (directory symlinks).
682 Changed read and write to go through pagecache. Added additional address space operations.
683 Memory mapped operations now working.
687 Added writepage code for additional memory mapping support. Fixed leak in xids causing
688 the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
689 every stat call. Additional formatting cleanup.
693 Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
697 Fixes from Zwane Mwaikambo for adding missing return code checking in a few places.
698 Also included a modified version of his fix to protect global list manipulation of
699 the smb session and tree connection and mid related global variables.
703 Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
704 changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
705 buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
709 More stylistic updates to better match kernel style. Add additional statistics
710 for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
711 and CIFS Packet Signing enablement.
715 Replace call to sleep_on with safer wait_on_event.
716 Make stylistic changes to better match kernel style recommendations.
717 Remove most typedef usage (except for the PDUs themselves).
721 Update mount so the -unc mount option is no longer required (the ip address can be specified
722 in a UNC style device name. Implementation of readpage/writepage started.
726 Fix intermittent problem with incorrect smb header checking on badly
727 fragmented tcp responses
731 Fixes to setting of allocation size and file size.
735 Various 2.5.38 fixes. Now works on 2.5.38
739 Prepare for 2.5 kernel merge. Remove ifdefs.
743 Socket buffer management fixes. Fix dual free.
747 Various big endian fixes for hardlinks and symlinks and also for dfs.
751 Various big endian fixes for servers with Unix extensions such as Samba
755 Various FindNext fixes for incorrect filenames on large directory searches on big endian
756 clients. basic posix file i/o tests now work on big endian machines, not just le
760 SessionSetup and NegotiateProtocol now work from Big Endian machines.
761 Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older
762 versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7).
766 Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
767 files now return the correct number of links on fstat as they are repeatedly linked and unlinked.
771 Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
772 session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
773 Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
774 (which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).
778 Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
779 it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
783 Rewrote much of connection and mount/unmount logic to handle bugs with
784 multiple uses to same share, multiple users to same server etc.
788 Fixed major problem with dentry corruption (missing call to dput)
792 Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
793 Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
794 although corresponding function not fully implemented in the vfs yet
798 Fixed dentry caching bug, misc. cleanup
802 Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
803 on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
804 Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
808 Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
809 and tested against Samba 2.2.5
814 1) Fixed lockrange to be correct (it was one byte too short)
816 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
817 show range as locked when there is a conflict with an existing lock.
819 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
820 in most cases. Eventually will offer optional ability to query server for the correct perms.
822 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
823 but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
826 4) Fixed error logging of valid mount options
828 5) Removed logging of password field.
830 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
831 and cleaned them up and made them more consistent with other cifs functions.
833 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
834 (with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
835 nor is the symlink support using the Unix extensions
837 8) Started adding the readlink and follow_link code
