3 Fix mtime bouncing around from local idea of last write times to remote time.
4 Fix hang (in i_size_read) when simultaneous size update of same remote file
5 on smp system corrupts sequence number. Do not reread unnecessarily partial page
6 (which we are about to overwrite anyway) when writing out file opened rw.
10 Fix oops in list_del during mount caused by unaligned string.
11 Fix file corruption which could occur on some large file
12 copies caused by writepages page i/o completion bug.
13 Seek to SEEK_END forces check for update of file size for non-cached
14 files. Allow file size to be updated on remote extend of locally open,
15 non-cached file. Fix reconnect to newer Samba servers (or other servers
16 which support the CIFS Unix/POSIX extensions) so that we again tell the
17 server the Unix/POSIX cifs capabilities which we support (SetFSInfo).
18 Add experimental support for new POSIX Open/Mkdir (which returns
19 stat information on the open, and allows setting the mode).
23 Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
24 Allow null user to be specified on mount ("username="). Do not return
25 EINVAL on readdir when filldir fails due to overwritten blocksize
26 (fixes FC problem). Return error in rename 2nd attempt retry (ie report
27 if rename by handle also fails, after rename by path fails, we were
28 not reporting whether the retry worked or not). Fix NTLMv2 to
29 work to Windows servers (mount with option "sec=ntlmv2").
33 Do not time out lockw calls when using posix extensions. Do not
34 time out requests if server still responding reasonably fast
35 on requests on other threads. Improve POSIX locking emulation,
36 (lock cancel now works, and unlock of merged range works even
37 to Windows servers now). Fix oops on mount to lanman servers
38 (win9x, os/2 etc.) when null password. Do not send listxattr
39 (SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
40 problem (instantiate inodes/dentries in right order for readdir).
44 Rewritten sessionsetup support, including support for legacy SMB
45 session setup needed for OS/2 and older servers such as Windows 95 and 98.
46 Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
47 so we can do search (ls etc.) to OS/2. Do not send NTCreateX
48 or recent levels of FindFirst unless server says it supports NT SMBs
49 (instead use legacy equivalents from LANMAN dialect). Fix to allow
50 NTLMv2 authentication support (now can use stronger password hashing
51 on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
52 Allow override of global cifs security flags on mount via "sec=" option(s).
56 POSIX locking to servers which support CIFS POSIX Extensions
57 (disabled by default controlled by proc/fs/cifs/Experimental).
58 Handle conversion of long share names (especially Asian languages)
59 to Unicode during mount. Fix memory leak in sess struct on reconnect.
60 Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
61 cifs open which helps rare case when setpathinfo fails or server does
66 Fix slow oplock break when mounted to different servers at the same time and
67 the tids match and we try to find matching fid on wrong server. Fix read
68 looping when signing required by server (2.6.16 kernel only). Fix readdir
69 vs. rename race which could cause each to hang. Return . and .. even
70 if server does not. Allow searches to skip first three entries and
71 begin at any location. Fix oops in find_writeable_file.
75 Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
76 configure stronger authentication. Fix sfu symlinks so they can
77 be followed (not just recognized). Fix wraparound of bcc on
78 read responses when buffer size over 64K and also fix wrap of
79 max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
80 cifs_user_read and cifs_readpages (when EAGAIN on send of smb
81 on socket is returned over and over). Add POSIX (advisory) byte range
82 locking support (requires server with newest CIFS UNIX Extensions
83 to the protocol implemented). Slow down negprot slightly in port 139
84 RFC1001 case to give session_init time on buggy servers.
88 Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
89 of readpages by eliminating one extra memcpy. Allow update of file size
90 from remote server even if file is open for write as long as mount is
91 directio. Recognize share mode security and send NTLM encrypted password
92 on tree connect if share mode negotiated.
96 Defer close of a file handle slightly if pending writes depend on that handle
97 (this reduces the EBADF bad file handle errors that can be logged under heavy
98 stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
99 Fix SFU style symlinks and mknod needed for servers which do not support the
100 CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
101 dentries so files that the client sees as deleted but that later get created
102 on the server will be recognized. Add client side permission check on setattr.
103 Timeout stuck requests better (where server has never responded or sent corrupt
108 Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
109 to be smaller at first (but increasing) so large write performance performance
110 over GigE is better. Do not hang thread on illegal byte range lock response
111 from Windows (Windows can send an RFC1001 size which does not match smb size) by
112 allowing an SMBs TCP length to be up to a few bytes longer than it should be.
113 wsize and rsize can now be larger than negotiated buffer size if server
114 supports large readx/writex, even when directio mount flag not specified.
115 Write size will in many cases now be 16K instead of 4K which greatly helps
116 file copy performance on lightly loaded networks. Fix oops in dnotify
117 when experimental config flag enabled. Make cifsFYI more granular.
121 Fix readdir caching when unlink removes file in current search buffer,
122 and this is followed by a rewind search to just before the deleted entry.
123 Do not attempt to set ctime unless atime and/or mtime change requested
124 (most servers throw it away anyway). Fix length check of received smbs
125 to be more accurate. Fix big endian problem with mapchars mount option,
126 and with a field returned by statfs.
130 Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
131 For these older servers, add option for passing netbios name of server in
132 on mount (servernetbiosname). Add suspend support for power management, to
133 avoid cifsd thread preventing software suspend from working.
134 Add mount option for disabling the default behavior of sending byte range lock
135 requests to the server (necessary for certain applications which break with
136 mandatory lock behavior such as Evolution), and also mount option for
137 requesting case insensitive matching for path based requests (requesting
138 case sensitive is the default).
142 Add writepage performance improvements. Fix path name conversions
143 for long filenames on mounts which were done with "mapchars" mount option
144 specified. Ensure multiplex ids do not collide. Fix case in which
145 rmmod can oops if done soon after last unmount. Fix truncated
146 search (readdir) output when resume filename was a long filename.
147 Fix filename conversion when mapchars mount option was specified and
148 filename was a long filename.
152 Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
153 Do not oops if root user kills cifs oplock kernel thread or
154 kills the cifsd thread (NB: killing the cifs kernel threads is not
155 recommended, unmount and rmmod cifs will kill them when they are
156 no longer needed). Fix readdir to ASCII servers (ie older servers
157 which do not support Unicode) and also require asterisk.
158 Fix out of memory case in which data could be written one page
159 off in the page cache.
163 Fix caching problem, in which readdir of directory containing a file
164 which was cached could cause the file's time stamp to be updated
165 without invalidating the readahead data (so we could get stale
166 file data on the client for that file even as the server copy changed).
167 Cleanup response processing so cifsd can not loop when abnormally
173 Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
174 transact response for an SMB request and search entry split across two frames.
175 Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
176 as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
177 unless server explicitly claims to support them in CIFS Unix extensions
178 POSIX ACL capability bit. Fix packet signing when multiuser mounting with
179 different users from the same client to the same server. Fix oops in
180 cifs_close. Add mount option for remapping reserved characters in
181 filenames (also allow recognizing files with created by SFU which have any
182 of these seven reserved characters, except backslash, to be recognized).
183 Fix invalid transact2 message (we were sometimes trying to interpret
184 oplock breaks as SMB responses). Add ioctl for checking that the
185 current uid matches the uid of the mounter (needed by umount.cifs).
186 Reduce the number of large buffer allocations in cifs response processing
187 (significantly reduces memory pressure under heavy stress with multiple
188 processes accessing the same server at the same time).
192 Fix updates of DOS attributes and time fields so that files on NT4 servers
193 do not get marked delete on close. Display sizes of cifs buffer pools in
194 cifs stats. Fix oops in unmount when cifsd thread being killed by
195 shutdown. Add generic readv/writev and aio support. Report inode numbers
196 consistently in readdir and lookup (when serverino mount option is
197 specified use the inode number that the server reports - for both lookup
198 and readdir, otherwise by default the locally generated inode number is used
199 for inodes created in either path since servers are not always able to
200 provide unique inode numbers when exporting multiple volumes from under one
205 Allow new nouser_xattr mount parm to disable xattr support for user namespace.
206 Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
207 (mostly affects NT4 servers) by retry with handle based network operation.
208 Add new POSIX Query FS Info for returning statfs info more accurately.
209 Handle passwords with multiple commas in them.
213 Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
214 Fix capabilities flags for large readx so as to allow reads larger than 64K.
218 Add module init parm for large SMB buffer size (to allow it to be changed
219 from its default of 16K) which is especially useful for large file copy
220 when mounting with the directio mount option. Fix oops after
221 returning from mount when experimental ExtendedSecurity enabled and
222 SpnegoNegotiated returning invalid error. Fix case to retry better when
223 peek returns from 1 to 3 bytes on socket which should have more data.
224 Fixed path based calls (such as cifs lookup) to handle path names
225 longer than 530 (now can handle PATH_MAX). Fix pass through authentication
226 from Samba server to DC (Samba required dummy LM password).
230 Turn off DNOTIFY (directory change notification support) by default
231 (unless built with the experimental flag) to fix hang with KDE
232 file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
233 waiting on an SMB response) in SendReceive when session dies but
234 reconnects quickly from another task. Add module init parms for
235 minimum number of large and small network buffers in the buffer pools,
236 and for the maximum number of simultaneous requests.
240 Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
241 and other POSIX CIFS compliant servers. Fix error mapping for getfacl
242 to EOPNOTSUPP when server does not support posix acls on the wire. Fix
243 improperly zeroed buffer in CIFS Unix extensions set times call.
247 Fix internationalization problem in cifs readdir with filenames that map to
248 longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
249 for readdir to netapp servers. Fix search rewind (seek into readdir to return
250 non-consecutive entries). Do not do readdir when server negotiates
251 buffer size to small to fit filename. Add support for reading POSIX ACLs from
252 the server (add also acl and noacl mount options).
256 Optionally allow using server side inode numbers, rather than client generated
257 ones by specifying mount option "serverino" - this is required for some apps
258 to work which double check hardlinked files and have persistent inode numbers.
262 Multiple bigendian fixes. On little endian systems (for reconnect after
263 network failure) fix tcp session reconnect code so we do not try first
264 to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
265 as directories rather than symlinks because we can do follow link on them.
269 Add config option to enable XATTR (extended attribute) support, mapping
270 xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
271 minor fixes pointed out by the Stanford SWAT checker (mostly missing
272 or out of order NULL pointer checks in little used error paths).
276 Add new mount parm to control whether mode check (generic_permission) is done
277 on the client. If Unix extensions are enabled and the uids on the client
278 and server do not match, client permission checks are meaningless on
279 server uids that do not exist on the client (this does not affect the
280 normal ACL check which occurs on the server). Fix default uid
281 on mknod to match create and mkdir. Add optional mount parm to allow
282 override of the default uid behavior (in which the server sets the uid
283 and gid of newly created files). Normally for network filesystem mounts
284 user want the server to set the uid/gid on newly created files (rather than
285 using uid of the client processes you would in a local filesystem).
289 Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
290 info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
291 (in build_wildcard_path_from_dentry). Fix mknod to pass type field
292 (block/char/fifo) properly. Remove spurious mount warning log entry when
293 credentials passed as mount argument. Set major/minor device number in
294 inode for block and char devices when unix extensions enabled.
298 Fix /proc/fs/cifs/Stats and DebugData display to handle larger
299 amounts of return data. Properly limit requests to MAX_REQ (50
300 is the usual maximum active multiplex SMB/CIFS requests per server).
301 Do not kill cifsd (and thus hurt the other SMB session) when more than one
302 session to the same server (but with different userids) exists and one
303 of the two user's smb sessions is being removed while leaving the other.
304 Do not loop reconnecting in cifsd demultiplex thread when admin
305 kills the thread without going through unmount.
309 Do not rename hardlinked files (since that should be a noop). Flush
310 cached write behind data when reopening a file after session abend,
311 except when already in write. Grab per socket sem during reconnect
312 to avoid oops in sendmsg if overlapping with reconnect. Do not
313 reset cached inode file size on readdir for files open for write on
319 Update number of blocks in file so du command is happier (in Linux a fake
320 blocksize of 512 is required for calculating number of blocks in inode).
321 Fix prepare write of partial pages to read in data from server if possible.
322 Fix race on tcpStatus field between unmount and reconnection code, causing
323 cifsd process sometimes to hang around forever. Improve out of memory
324 checks in cifs_filldir
328 Fix incorrect file size in file handle based setattr on big endian hardware.
329 Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
330 and closing file structs in writepage/partialpagewrite. Add statistics
331 for each mounted share (new menuconfig option). Fix endianness problem in
332 volume information displayed in /proc/fs/cifs/DebugData (only affects
333 affects big endian architectures). Prevent renames while constructing
334 path names for open, mkdir and rmdir.
338 Change to mempools for alloc smb request buffers and multiplex structs
339 to better handle low memory problems (and potential deadlocks).
343 Fix incomplete listings of large directories on Samba servers when Unix
344 extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
345 rename deadlock when writing out dirty pages at same time.
349 Fix open of files in which O_CREATE can cause the mode to change in
350 some cases. Fix case in which retry of write overlaps file close.
351 Fix PPC64 build error. Reduce excessive stack usage in smb password
352 hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
356 Fixes for large file copy, signal handling, socket retry, buffer
357 allocation and low memory situations.
361 Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
362 also now allowing support for specifying client netbiosname. NT4 support added.
366 Fix reconnection (and certain failed mounts) to properly wake up the
367 blocked users thread so it does not seem hung (in some cases was blocked
368 until the cifs receive timeout expired). Fix spurious error logging
369 to kernel log when application with open network files killed.
373 Fix /proc/fs module unload warning message (that could be logged
374 to the kernel log). Fix intermittent failure in connectathon
375 test7 (hardlink count not immediately refreshed in case in which
376 inode metadata can be incorrectly kept cached when time near zero)
380 Allow file_mode and dir_mode (specified at mount time) to be enforced
381 locally (the server already enforced its own ACLs too) for servers
382 that do not report the correct mode (do not support the
383 CIFS Unix Extensions).
387 Fix some small memory leaks in some unmount error paths. Fix major leak
388 of cache pages in readpages causing multiple read oriented stress
389 testcases (including fsx, and even large file copy) to fail over time.
393 Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
394 This allows files that differ only in case and improves performance of file
395 creation and file open to such servers. Fix semaphore conflict which causes
396 slow delete of open file to Samba (which unfortunately can cause an oplock
397 break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
401 fixes to cifs_readpages for fsx test case
405 Fix caching data integrity bug when extending file size especially when no
406 oplock on file. Fix spurious logging of valid already parsed mount options
407 that are parsed outside of the cifs vfs such as nosuid.
412 Connect to server when port number override not specified, and tcp port
413 unitialized. Reset search to restart at correct file when kernel routine
414 filldir returns error during large directory searches (readdir).
418 Fix caching problem when files opened by multiple clients in which
419 page cache could contain stale data, and write through did
420 not occur often enough while file was still open when read ahead
421 (read oplock) not allowed. Treat "sep=" when first mount option
422 as an override of comma as the default separator between mount
427 Allow passwords longer than 16 bytes. Allow null password string.
431 Gracefully clean up failed mounts when attempting to mount to servers such as
432 Windows 98 that terminate tcp sessions during protocol negotiation. Handle
433 embedded commas in mount parsing of passwords.
437 Invalidate local inode cached pages on oplock break and when last file
438 instance is closed so that the client does not continue using stale local
439 copy rather than later modified server copy of file. Do not reconnect
440 when server drops the tcp session prematurely before negotiate
441 protocol response. Fix oops in reopen_file when dentry freed. Allow
442 the support for CIFS Unix Extensions to be disabled via proc interface.
446 Fix hang in commit_write during reconnection of open files under heavy load.
447 Fix unload_nls oops in a mount failure path. Serialize writes to same socket
448 which also fixes any possible races when cifs signatures are enabled in SMBs
449 being sent out of signature sequence number order.
453 Fix byte range locking bug (endian problem) causing bad offset and
458 Fix oops (in send_sig) caused by CIFS unmount code trying to
459 wake up the demultiplex thread after it had exited. Do not log
460 error on harmless oplock release of closed handle.
464 Fix unsafe global variable usage and password hash failure on gcc 3.3.1
465 Fix problem reconnecting secondary mounts to same server after session
466 failure. Fix invalid dentry - race in mkdir when directory gets created
467 by another client between the lookup and mkdir.
471 Fix to list processing in reopen_files. Fix reconnection when server hung
472 but tcpip session still alive. Set proper timeout on socket read.
476 Add missing mount options including iocharset. SMP fixes in write and open.
477 Fix errors in reconnecting after TCP session failure. Fix module unloading
478 of default nls codepage
482 Active smb transactions should never go negative (fix double FreeXid). Fix
483 list processing in file routines. Check return code on kmalloc in open.
484 Fix spinlock usage for SMP.
488 Fix oops in reopen_files when invalid dentry. drop dentry on server rename
489 and on revalidate errors. Fix cases where pid is now tgid. Fix return code
490 on create hard link when server does not support them.
494 Fix scheduling while atomic error in getting inode info on newly created file.
495 Fix truncate of existing files opened with O_CREAT but not O_TRUNC set.
499 Fix oops on write to dead tcp session. Remove error log write for case when file open
500 O_CREAT but not O_EXCL
504 Fix non-POSIX behavior on rename of open file and delete of open file by taking
505 advantage of trans2 SetFileInfo rename facility if available on target server.
506 Retry on ENOSPC and EAGAIN socket errors.
510 Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix
511 allocation size miscalculation. After oplock token lost do not read through
516 Fix oops on empty file readahead. Fix for file size handling for locally cached files.
520 Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files
521 during auto reconnection to server after server recovered from failure.
525 Finish support for Linux 2.5 open/create changes, which removes the
526 redundant NTCreate/QPathInfo/close that was sent during file create.
527 Enable oplock by default. Enable packet signing by default (needed to
528 access many recent Windows servers)
532 Fix oops when mounting to long server names caused by inverted parms to kmalloc.
533 Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
534 we will choose a cifs user session (smb uid) that better matches the local
535 uid if a) the mount uid does not match the current uid and b) we have another
536 session to the same server (ip address) for a different mount which
537 matches the current local uid.
541 Add support for mknod of block or character devices. Fix oplock
542 code (distributed caching) to properly send response to oplock
547 Finish up CIFS packet digital signing for the default
548 NTLM security case. This should help Windows 2003
549 network interoperability since it is common for
550 packet signing to be required now. Fix statfs (stat -f)
551 which recently started returning errors due to
552 invalid value (-1 instead of 0) being set in the
553 struct kstatfs f_ffiles field.
557 Fix oops on stopping oplock thread when removing cifs when
562 Fix mount options for ro (readonly), uid, gid and file and directory mode.
566 Fix errors displayed on failed mounts to be more understandable.
567 Fixed various incorrect or misleading smb to posix error code mappings.
571 Fix display of NTFS DFS junctions to display as symlinks.
572 They are the network equivalent. Fix oops in
573 cifs_partialpagewrite caused by missing spinlock protection
574 of openfile linked list. Allow writebehind caching errors to
575 be returned to the application at file close.
579 Clean up options displayed in /proc/mounts by show_options to
580 be more consistent with other filesystems.
584 Fix delete of readonly file to Windows servers. Reflect
585 presence or absence of read only dos attribute in mode
586 bits for servers that do not support CIFS Unix extensions.
587 Fix shortened results on readdir of large directories to
588 servers supporting CIFS Unix extensions (caused by
589 incorrect resume key).
593 Fix truncate bug (set file size) that could cause hangs e.g. running fsx
597 unload nls if mount fails.
601 Add resume key support to search (readdir) code to workaround
602 Windows bug. Add /proc/fs/cifs/LookupCacheEnable which
603 allows disabling caching of attribute information for
608 Add more oplock handling (distributed caching code). Remove
609 dead code. Remove excessive stack space utilization from
614 Fix oops in get dfs referral (triggered when null path sent in to
615 mount). Add support for overriding rsize at mount time.
619 Fix buffer overrun in readdir which caused intermittent kernel oopses.
620 Fix writepage code to release kmap on write data. Allow "-ip=" new
621 mount option to be passed in on parameter distinct from the first part
622 (server name portion of) the UNC name. Allow override of the
623 tcp port of the target server via new mount option "-port="
627 Fix search handle leak on rewind. Fix setuid and gid so that they are
628 reflected in the local inode immediately. Cleanup of whitespace
629 to make 2.4 and 2.5 versions more consistent.
634 Fix signal sending so that captive thread (cifsd) exits on umount
635 (which was causing the warning in kmem_cache_free of the request buffers
636 at rmmod time). This had broken as a sideeffect of the recent global
637 kernel change to daemonize. Fix memory leak in readdir code which
638 showed up in "ls -R" (and applications that did search rewinding).
642 Reconnect tids and fids after session reconnection (still do not
643 reconnect byte range locks though). Fix problem caching
644 lookup information for directory inodes, improving performance,
645 especially in deep directory trees. Fix various build warnings.
649 Finish fixes to commit write for caching/readahead consistency. fsx
650 now works to Samba servers. Fix oops caused when readahead
651 was interrupted by a signal.
655 Fix data corruption (in partial page after truncate) that caused fsx to
656 fail to Windows servers. Cleaned up some extraneous error logging in
657 common error paths. Add generic sendfile support.
661 Fix memory leak in AllocMidQEntry.
662 Finish reconnection logic, so connection with server can be dropped
663 (or server rebooted) and the cifs client will reconnect.
667 Fix temporary socket leak when bad userid or password specified
668 (or other SMBSessSetup failure). Increase maximum buffer size to slightly
669 over 16K to allow negotiation of up to Samba and Windows server default read
670 sizes. Add support for readpages
674 Fix oops when username not passed in on mount. Extensive fixes and improvements
675 to error logging (strip redundant newlines, change debug macros to ensure newline
676 passed in and to be more consistent). Fix writepage wrong file handle problem,
677 a readonly file handle could be incorrectly used to attempt to write out
678 file updates through the page cache to multiply open files. This could cause
679 the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
680 shares to the same Windows server when using different usernames
681 (doing this to Samba servers worked but Windows was rejecting it) - now it is
682 possible to use different userids when connecting to the same server from a
683 Linux client. Fix oops when treeDisconnect called during unmount on
684 previously freed socket.
688 Fix oops in readpages caused by not setting address space operations in inode in
693 Includes support for deleting of open files and renaming over existing files (per POSIX
694 requirement). Add readlink support for Windows junction points (directory symlinks).
698 Changed read and write to go through pagecache. Added additional address space operations.
699 Memory mapped operations now working.
703 Added writepage code for additional memory mapping support. Fixed leak in xids causing
704 the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
705 every stat call. Additional formatting cleanup.
709 Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
713 Fixes from Zwane Mwaikambo for adding missing return code checking in a few places.
714 Also included a modified version of his fix to protect global list manipulation of
715 the smb session and tree connection and mid related global variables.
719 Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
720 changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
721 buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
725 More stylistic updates to better match kernel style. Add additional statistics
726 for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
727 and CIFS Packet Signing enablement.
731 Replace call to sleep_on with safer wait_on_event.
732 Make stylistic changes to better match kernel style recommendations.
733 Remove most typedef usage (except for the PDUs themselves).
737 Update mount so the -unc mount option is no longer required (the ip address can be specified
738 in a UNC style device name. Implementation of readpage/writepage started.
742 Fix intermittent problem with incorrect smb header checking on badly
743 fragmented tcp responses
747 Fixes to setting of allocation size and file size.
751 Various 2.5.38 fixes. Now works on 2.5.38
755 Prepare for 2.5 kernel merge. Remove ifdefs.
759 Socket buffer management fixes. Fix dual free.
763 Various big endian fixes for hardlinks and symlinks and also for dfs.
767 Various big endian fixes for servers with Unix extensions such as Samba
771 Various FindNext fixes for incorrect filenames on large directory searches on big endian
772 clients. basic posix file i/o tests now work on big endian machines, not just le
776 SessionSetup and NegotiateProtocol now work from Big Endian machines.
777 Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older
778 versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7).
782 Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
783 files now return the correct number of links on fstat as they are repeatedly linked and unlinked.
787 Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
788 session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
789 Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
790 (which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).
794 Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
795 it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
799 Rewrote much of connection and mount/unmount logic to handle bugs with
800 multiple uses to same share, multiple users to same server etc.
804 Fixed major problem with dentry corruption (missing call to dput)
808 Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
809 Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
810 although corresponding function not fully implemented in the vfs yet
814 Fixed dentry caching bug, misc. cleanup
818 Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
819 on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
820 Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
824 Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
825 and tested against Samba 2.2.5
830 1) Fixed lockrange to be correct (it was one byte too short)
832 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
833 show range as locked when there is a conflict with an existing lock.
835 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
836 in most cases. Eventually will offer optional ability to query server for the correct perms.
838 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
839 but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
842 4) Fixed error logging of valid mount options
844 5) Removed logging of password field.
846 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
847 and cleaned them up and made them more consistent with other cifs functions.
849 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
850 (with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
851 nor is the symlink support using the Unix extensions
853 8) Started adding the readlink and follow_link code
