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.
7 When DOS attribute of file on non-Unix server's file changes on the server side
8 from read-only back to read-write, reflect this change in default file mode
9 (we had been leaving a file's mode read-only until the inode were reloaded).
10 Allow setting of attribute back to ATTR_NORMAL (removing readonly dos attribute
11 when archive dos attribute not set and we are changing mode back to writeable
12 on server which does not support the Unix Extensions). Remove read only dos
13 attribute on chmod when adding any write permission (ie on any of
14 user/group/other (not all of user/group/other ie 0222) when
15 mounted to windows. Add support for POSIX MkDir (slight performance
16 enhancement and eliminates the network race between the mkdir and set
17 path info of the mode).
22 Fix oops in list_del during mount caused by unaligned string.
23 Fix file corruption which could occur on some large file
24 copies caused by writepages page i/o completion bug.
25 Seek to SEEK_END forces check for update of file size for non-cached
26 files. Allow file size to be updated on remote extend of locally open,
27 non-cached file. Fix reconnect to newer Samba servers (or other servers
28 which support the CIFS Unix/POSIX extensions) so that we again tell the
29 server the Unix/POSIX cifs capabilities which we support (SetFSInfo).
30 Add experimental support for new POSIX Open/Mkdir (which returns
31 stat information on the open, and allows setting the mode).
35 Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
36 Allow null user to be specified on mount ("username="). Do not return
37 EINVAL on readdir when filldir fails due to overwritten blocksize
38 (fixes FC problem). Return error in rename 2nd attempt retry (ie report
39 if rename by handle also fails, after rename by path fails, we were
40 not reporting whether the retry worked or not). Fix NTLMv2 to
41 work to Windows servers (mount with option "sec=ntlmv2").
45 Do not time out lockw calls when using posix extensions. Do not
46 time out requests if server still responding reasonably fast
47 on requests on other threads. Improve POSIX locking emulation,
48 (lock cancel now works, and unlock of merged range works even
49 to Windows servers now). Fix oops on mount to lanman servers
50 (win9x, os/2 etc.) when null password. Do not send listxattr
51 (SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
52 problem (instantiate inodes/dentries in right order for readdir).
56 Rewritten sessionsetup support, including support for legacy SMB
57 session setup needed for OS/2 and older servers such as Windows 95 and 98.
58 Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
59 so we can do search (ls etc.) to OS/2. Do not send NTCreateX
60 or recent levels of FindFirst unless server says it supports NT SMBs
61 (instead use legacy equivalents from LANMAN dialect). Fix to allow
62 NTLMv2 authentication support (now can use stronger password hashing
63 on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
64 Allow override of global cifs security flags on mount via "sec=" option(s).
68 POSIX locking to servers which support CIFS POSIX Extensions
69 (disabled by default controlled by proc/fs/cifs/Experimental).
70 Handle conversion of long share names (especially Asian languages)
71 to Unicode during mount. Fix memory leak in sess struct on reconnect.
72 Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
73 cifs open which helps rare case when setpathinfo fails or server does
78 Fix slow oplock break when mounted to different servers at the same time and
79 the tids match and we try to find matching fid on wrong server. Fix read
80 looping when signing required by server (2.6.16 kernel only). Fix readdir
81 vs. rename race which could cause each to hang. Return . and .. even
82 if server does not. Allow searches to skip first three entries and
83 begin at any location. Fix oops in find_writeable_file.
87 Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
88 configure stronger authentication. Fix sfu symlinks so they can
89 be followed (not just recognized). Fix wraparound of bcc on
90 read responses when buffer size over 64K and also fix wrap of
91 max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
92 cifs_user_read and cifs_readpages (when EAGAIN on send of smb
93 on socket is returned over and over). Add POSIX (advisory) byte range
94 locking support (requires server with newest CIFS UNIX Extensions
95 to the protocol implemented). Slow down negprot slightly in port 139
96 RFC1001 case to give session_init time on buggy servers.
100 Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
101 of readpages by eliminating one extra memcpy. Allow update of file size
102 from remote server even if file is open for write as long as mount is
103 directio. Recognize share mode security and send NTLM encrypted password
104 on tree connect if share mode negotiated.
108 Defer close of a file handle slightly if pending writes depend on that handle
109 (this reduces the EBADF bad file handle errors that can be logged under heavy
110 stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
111 Fix SFU style symlinks and mknod needed for servers which do not support the
112 CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
113 dentries so files that the client sees as deleted but that later get created
114 on the server will be recognized. Add client side permission check on setattr.
115 Timeout stuck requests better (where server has never responded or sent corrupt
120 Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
121 to be smaller at first (but increasing) so large write performance performance
122 over GigE is better. Do not hang thread on illegal byte range lock response
123 from Windows (Windows can send an RFC1001 size which does not match smb size) by
124 allowing an SMBs TCP length to be up to a few bytes longer than it should be.
125 wsize and rsize can now be larger than negotiated buffer size if server
126 supports large readx/writex, even when directio mount flag not specified.
127 Write size will in many cases now be 16K instead of 4K which greatly helps
128 file copy performance on lightly loaded networks. Fix oops in dnotify
129 when experimental config flag enabled. Make cifsFYI more granular.
133 Fix readdir caching when unlink removes file in current search buffer,
134 and this is followed by a rewind search to just before the deleted entry.
135 Do not attempt to set ctime unless atime and/or mtime change requested
136 (most servers throw it away anyway). Fix length check of received smbs
137 to be more accurate. Fix big endian problem with mapchars mount option,
138 and with a field returned by statfs.
142 Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
143 For these older servers, add option for passing netbios name of server in
144 on mount (servernetbiosname). Add suspend support for power management, to
145 avoid cifsd thread preventing software suspend from working.
146 Add mount option for disabling the default behavior of sending byte range lock
147 requests to the server (necessary for certain applications which break with
148 mandatory lock behavior such as Evolution), and also mount option for
149 requesting case insensitive matching for path based requests (requesting
150 case sensitive is the default).
154 Add writepage performance improvements. Fix path name conversions
155 for long filenames on mounts which were done with "mapchars" mount option
156 specified. Ensure multiplex ids do not collide. Fix case in which
157 rmmod can oops if done soon after last unmount. Fix truncated
158 search (readdir) output when resume filename was a long filename.
159 Fix filename conversion when mapchars mount option was specified and
160 filename was a long filename.
164 Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
165 Do not oops if root user kills cifs oplock kernel thread or
166 kills the cifsd thread (NB: killing the cifs kernel threads is not
167 recommended, unmount and rmmod cifs will kill them when they are
168 no longer needed). Fix readdir to ASCII servers (ie older servers
169 which do not support Unicode) and also require asterisk.
170 Fix out of memory case in which data could be written one page
171 off in the page cache.
175 Fix caching problem, in which readdir of directory containing a file
176 which was cached could cause the file's time stamp to be updated
177 without invalidating the readahead data (so we could get stale
178 file data on the client for that file even as the server copy changed).
179 Cleanup response processing so cifsd can not loop when abnormally
185 Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
186 transact response for an SMB request and search entry split across two frames.
187 Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
188 as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
189 unless server explicitly claims to support them in CIFS Unix extensions
190 POSIX ACL capability bit. Fix packet signing when multiuser mounting with
191 different users from the same client to the same server. Fix oops in
192 cifs_close. Add mount option for remapping reserved characters in
193 filenames (also allow recognizing files with created by SFU which have any
194 of these seven reserved characters, except backslash, to be recognized).
195 Fix invalid transact2 message (we were sometimes trying to interpret
196 oplock breaks as SMB responses). Add ioctl for checking that the
197 current uid matches the uid of the mounter (needed by umount.cifs).
198 Reduce the number of large buffer allocations in cifs response processing
199 (significantly reduces memory pressure under heavy stress with multiple
200 processes accessing the same server at the same time).
204 Fix updates of DOS attributes and time fields so that files on NT4 servers
205 do not get marked delete on close. Display sizes of cifs buffer pools in
206 cifs stats. Fix oops in unmount when cifsd thread being killed by
207 shutdown. Add generic readv/writev and aio support. Report inode numbers
208 consistently in readdir and lookup (when serverino mount option is
209 specified use the inode number that the server reports - for both lookup
210 and readdir, otherwise by default the locally generated inode number is used
211 for inodes created in either path since servers are not always able to
212 provide unique inode numbers when exporting multiple volumes from under one
217 Allow new nouser_xattr mount parm to disable xattr support for user namespace.
218 Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
219 (mostly affects NT4 servers) by retry with handle based network operation.
220 Add new POSIX Query FS Info for returning statfs info more accurately.
221 Handle passwords with multiple commas in them.
225 Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
226 Fix capabilities flags for large readx so as to allow reads larger than 64K.
230 Add module init parm for large SMB buffer size (to allow it to be changed
231 from its default of 16K) which is especially useful for large file copy
232 when mounting with the directio mount option. Fix oops after
233 returning from mount when experimental ExtendedSecurity enabled and
234 SpnegoNegotiated returning invalid error. Fix case to retry better when
235 peek returns from 1 to 3 bytes on socket which should have more data.
236 Fixed path based calls (such as cifs lookup) to handle path names
237 longer than 530 (now can handle PATH_MAX). Fix pass through authentication
238 from Samba server to DC (Samba required dummy LM password).
242 Turn off DNOTIFY (directory change notification support) by default
243 (unless built with the experimental flag) to fix hang with KDE
244 file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
245 waiting on an SMB response) in SendReceive when session dies but
246 reconnects quickly from another task. Add module init parms for
247 minimum number of large and small network buffers in the buffer pools,
248 and for the maximum number of simultaneous requests.
252 Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
253 and other POSIX CIFS compliant servers. Fix error mapping for getfacl
254 to EOPNOTSUPP when server does not support posix acls on the wire. Fix
255 improperly zeroed buffer in CIFS Unix extensions set times call.
259 Fix internationalization problem in cifs readdir with filenames that map to
260 longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
261 for readdir to netapp servers. Fix search rewind (seek into readdir to return
262 non-consecutive entries). Do not do readdir when server negotiates
263 buffer size to small to fit filename. Add support for reading POSIX ACLs from
264 the server (add also acl and noacl mount options).
268 Optionally allow using server side inode numbers, rather than client generated
269 ones by specifying mount option "serverino" - this is required for some apps
270 to work which double check hardlinked files and have persistent inode numbers.
274 Multiple bigendian fixes. On little endian systems (for reconnect after
275 network failure) fix tcp session reconnect code so we do not try first
276 to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
277 as directories rather than symlinks because we can do follow link on them.
281 Add config option to enable XATTR (extended attribute) support, mapping
282 xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
283 minor fixes pointed out by the Stanford SWAT checker (mostly missing
284 or out of order NULL pointer checks in little used error paths).
288 Add new mount parm to control whether mode check (generic_permission) is done
289 on the client. If Unix extensions are enabled and the uids on the client
290 and server do not match, client permission checks are meaningless on
291 server uids that do not exist on the client (this does not affect the
292 normal ACL check which occurs on the server). Fix default uid
293 on mknod to match create and mkdir. Add optional mount parm to allow
294 override of the default uid behavior (in which the server sets the uid
295 and gid of newly created files). Normally for network filesystem mounts
296 user want the server to set the uid/gid on newly created files (rather than
297 using uid of the client processes you would in a local filesystem).
301 Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
302 info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
303 (in build_wildcard_path_from_dentry). Fix mknod to pass type field
304 (block/char/fifo) properly. Remove spurious mount warning log entry when
305 credentials passed as mount argument. Set major/minor device number in
306 inode for block and char devices when unix extensions enabled.
310 Fix /proc/fs/cifs/Stats and DebugData display to handle larger
311 amounts of return data. Properly limit requests to MAX_REQ (50
312 is the usual maximum active multiplex SMB/CIFS requests per server).
313 Do not kill cifsd (and thus hurt the other SMB session) when more than one
314 session to the same server (but with different userids) exists and one
315 of the two user's smb sessions is being removed while leaving the other.
316 Do not loop reconnecting in cifsd demultiplex thread when admin
317 kills the thread without going through unmount.
321 Do not rename hardlinked files (since that should be a noop). Flush
322 cached write behind data when reopening a file after session abend,
323 except when already in write. Grab per socket sem during reconnect
324 to avoid oops in sendmsg if overlapping with reconnect. Do not
325 reset cached inode file size on readdir for files open for write on
331 Update number of blocks in file so du command is happier (in Linux a fake
332 blocksize of 512 is required for calculating number of blocks in inode).
333 Fix prepare write of partial pages to read in data from server if possible.
334 Fix race on tcpStatus field between unmount and reconnection code, causing
335 cifsd process sometimes to hang around forever. Improve out of memory
336 checks in cifs_filldir
340 Fix incorrect file size in file handle based setattr on big endian hardware.
341 Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
342 and closing file structs in writepage/partialpagewrite. Add statistics
343 for each mounted share (new menuconfig option). Fix endianness problem in
344 volume information displayed in /proc/fs/cifs/DebugData (only affects
345 affects big endian architectures). Prevent renames while constructing
346 path names for open, mkdir and rmdir.
350 Change to mempools for alloc smb request buffers and multiplex structs
351 to better handle low memory problems (and potential deadlocks).
355 Fix incomplete listings of large directories on Samba servers when Unix
356 extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
357 rename deadlock when writing out dirty pages at same time.
361 Fix open of files in which O_CREATE can cause the mode to change in
362 some cases. Fix case in which retry of write overlaps file close.
363 Fix PPC64 build error. Reduce excessive stack usage in smb password
364 hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
368 Fixes for large file copy, signal handling, socket retry, buffer
369 allocation and low memory situations.
373 Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
374 also now allowing support for specifying client netbiosname. NT4 support added.
378 Fix reconnection (and certain failed mounts) to properly wake up the
379 blocked users thread so it does not seem hung (in some cases was blocked
380 until the cifs receive timeout expired). Fix spurious error logging
381 to kernel log when application with open network files killed.
385 Fix /proc/fs module unload warning message (that could be logged
386 to the kernel log). Fix intermittent failure in connectathon
387 test7 (hardlink count not immediately refreshed in case in which
388 inode metadata can be incorrectly kept cached when time near zero)
392 Allow file_mode and dir_mode (specified at mount time) to be enforced
393 locally (the server already enforced its own ACLs too) for servers
394 that do not report the correct mode (do not support the
395 CIFS Unix Extensions).
399 Fix some small memory leaks in some unmount error paths. Fix major leak
400 of cache pages in readpages causing multiple read oriented stress
401 testcases (including fsx, and even large file copy) to fail over time.
405 Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
406 This allows files that differ only in case and improves performance of file
407 creation and file open to such servers. Fix semaphore conflict which causes
408 slow delete of open file to Samba (which unfortunately can cause an oplock
409 break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
413 fixes to cifs_readpages for fsx test case
417 Fix caching data integrity bug when extending file size especially when no
418 oplock on file. Fix spurious logging of valid already parsed mount options
419 that are parsed outside of the cifs vfs such as nosuid.
424 Connect to server when port number override not specified, and tcp port
425 unitialized. Reset search to restart at correct file when kernel routine
426 filldir returns error during large directory searches (readdir).
430 Fix caching problem when files opened by multiple clients in which
431 page cache could contain stale data, and write through did
432 not occur often enough while file was still open when read ahead
433 (read oplock) not allowed. Treat "sep=" when first mount option
434 as an override of comma as the default separator between mount
439 Allow passwords longer than 16 bytes. Allow null password string.
443 Gracefully clean up failed mounts when attempting to mount to servers such as
444 Windows 98 that terminate tcp sessions during protocol negotiation. Handle
445 embedded commas in mount parsing of passwords.
449 Invalidate local inode cached pages on oplock break and when last file
450 instance is closed so that the client does not continue using stale local
451 copy rather than later modified server copy of file. Do not reconnect
452 when server drops the tcp session prematurely before negotiate
453 protocol response. Fix oops in reopen_file when dentry freed. Allow
454 the support for CIFS Unix Extensions to be disabled via proc interface.
458 Fix hang in commit_write during reconnection of open files under heavy load.
459 Fix unload_nls oops in a mount failure path. Serialize writes to same socket
460 which also fixes any possible races when cifs signatures are enabled in SMBs
461 being sent out of signature sequence number order.
465 Fix byte range locking bug (endian problem) causing bad offset and
470 Fix oops (in send_sig) caused by CIFS unmount code trying to
471 wake up the demultiplex thread after it had exited. Do not log
472 error on harmless oplock release of closed handle.
476 Fix unsafe global variable usage and password hash failure on gcc 3.3.1
477 Fix problem reconnecting secondary mounts to same server after session
478 failure. Fix invalid dentry - race in mkdir when directory gets created
479 by another client between the lookup and mkdir.
483 Fix to list processing in reopen_files. Fix reconnection when server hung
484 but tcpip session still alive. Set proper timeout on socket read.
488 Add missing mount options including iocharset. SMP fixes in write and open.
489 Fix errors in reconnecting after TCP session failure. Fix module unloading
490 of default nls codepage
494 Active smb transactions should never go negative (fix double FreeXid). Fix
495 list processing in file routines. Check return code on kmalloc in open.
496 Fix spinlock usage for SMP.
500 Fix oops in reopen_files when invalid dentry. drop dentry on server rename
501 and on revalidate errors. Fix cases where pid is now tgid. Fix return code
502 on create hard link when server does not support them.
506 Fix scheduling while atomic error in getting inode info on newly created file.
507 Fix truncate of existing files opened with O_CREAT but not O_TRUNC set.
511 Fix oops on write to dead tcp session. Remove error log write for case when file open
512 O_CREAT but not O_EXCL
516 Fix non-POSIX behavior on rename of open file and delete of open file by taking
517 advantage of trans2 SetFileInfo rename facility if available on target server.
518 Retry on ENOSPC and EAGAIN socket errors.
522 Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix
523 allocation size miscalculation. After oplock token lost do not read through
528 Fix oops on empty file readahead. Fix for file size handling for locally cached files.
532 Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files
533 during auto reconnection to server after server recovered from failure.
537 Finish support for Linux 2.5 open/create changes, which removes the
538 redundant NTCreate/QPathInfo/close that was sent during file create.
539 Enable oplock by default. Enable packet signing by default (needed to
540 access many recent Windows servers)
544 Fix oops when mounting to long server names caused by inverted parms to kmalloc.
545 Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
546 we will choose a cifs user session (smb uid) that better matches the local
547 uid if a) the mount uid does not match the current uid and b) we have another
548 session to the same server (ip address) for a different mount which
549 matches the current local uid.
553 Add support for mknod of block or character devices. Fix oplock
554 code (distributed caching) to properly send response to oplock
559 Finish up CIFS packet digital signing for the default
560 NTLM security case. This should help Windows 2003
561 network interoperability since it is common for
562 packet signing to be required now. Fix statfs (stat -f)
563 which recently started returning errors due to
564 invalid value (-1 instead of 0) being set in the
565 struct kstatfs f_ffiles field.
569 Fix oops on stopping oplock thread when removing cifs when
574 Fix mount options for ro (readonly), uid, gid and file and directory mode.
578 Fix errors displayed on failed mounts to be more understandable.
579 Fixed various incorrect or misleading smb to posix error code mappings.
583 Fix display of NTFS DFS junctions to display as symlinks.
584 They are the network equivalent. Fix oops in
585 cifs_partialpagewrite caused by missing spinlock protection
586 of openfile linked list. Allow writebehind caching errors to
587 be returned to the application at file close.
591 Clean up options displayed in /proc/mounts by show_options to
592 be more consistent with other filesystems.
596 Fix delete of readonly file to Windows servers. Reflect
597 presence or absence of read only dos attribute in mode
598 bits for servers that do not support CIFS Unix extensions.
599 Fix shortened results on readdir of large directories to
600 servers supporting CIFS Unix extensions (caused by
601 incorrect resume key).
605 Fix truncate bug (set file size) that could cause hangs e.g. running fsx
609 unload nls if mount fails.
613 Add resume key support to search (readdir) code to workaround
614 Windows bug. Add /proc/fs/cifs/LookupCacheEnable which
615 allows disabling caching of attribute information for
620 Add more oplock handling (distributed caching code). Remove
621 dead code. Remove excessive stack space utilization from
626 Fix oops in get dfs referral (triggered when null path sent in to
627 mount). Add support for overriding rsize at mount time.
631 Fix buffer overrun in readdir which caused intermittent kernel oopses.
632 Fix writepage code to release kmap on write data. Allow "-ip=" new
633 mount option to be passed in on parameter distinct from the first part
634 (server name portion of) the UNC name. Allow override of the
635 tcp port of the target server via new mount option "-port="
639 Fix search handle leak on rewind. Fix setuid and gid so that they are
640 reflected in the local inode immediately. Cleanup of whitespace
641 to make 2.4 and 2.5 versions more consistent.
646 Fix signal sending so that captive thread (cifsd) exits on umount
647 (which was causing the warning in kmem_cache_free of the request buffers
648 at rmmod time). This had broken as a sideeffect of the recent global
649 kernel change to daemonize. Fix memory leak in readdir code which
650 showed up in "ls -R" (and applications that did search rewinding).
654 Reconnect tids and fids after session reconnection (still do not
655 reconnect byte range locks though). Fix problem caching
656 lookup information for directory inodes, improving performance,
657 especially in deep directory trees. Fix various build warnings.
661 Finish fixes to commit write for caching/readahead consistency. fsx
662 now works to Samba servers. Fix oops caused when readahead
663 was interrupted by a signal.
667 Fix data corruption (in partial page after truncate) that caused fsx to
668 fail to Windows servers. Cleaned up some extraneous error logging in
669 common error paths. Add generic sendfile support.
673 Fix memory leak in AllocMidQEntry.
674 Finish reconnection logic, so connection with server can be dropped
675 (or server rebooted) and the cifs client will reconnect.
679 Fix temporary socket leak when bad userid or password specified
680 (or other SMBSessSetup failure). Increase maximum buffer size to slightly
681 over 16K to allow negotiation of up to Samba and Windows server default read
682 sizes. Add support for readpages
686 Fix oops when username not passed in on mount. Extensive fixes and improvements
687 to error logging (strip redundant newlines, change debug macros to ensure newline
688 passed in and to be more consistent). Fix writepage wrong file handle problem,
689 a readonly file handle could be incorrectly used to attempt to write out
690 file updates through the page cache to multiply open files. This could cause
691 the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
692 shares to the same Windows server when using different usernames
693 (doing this to Samba servers worked but Windows was rejecting it) - now it is
694 possible to use different userids when connecting to the same server from a
695 Linux client. Fix oops when treeDisconnect called during unmount on
696 previously freed socket.
700 Fix oops in readpages caused by not setting address space operations in inode in
705 Includes support for deleting of open files and renaming over existing files (per POSIX
706 requirement). Add readlink support for Windows junction points (directory symlinks).
710 Changed read and write to go through pagecache. Added additional address space operations.
711 Memory mapped operations now working.
715 Added writepage code for additional memory mapping support. Fixed leak in xids causing
716 the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
717 every stat call. Additional formatting cleanup.
721 Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
725 Fixes from Zwane Mwaikambo for adding missing return code checking in a few places.
726 Also included a modified version of his fix to protect global list manipulation of
727 the smb session and tree connection and mid related global variables.
731 Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
732 changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
733 buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
737 More stylistic updates to better match kernel style. Add additional statistics
738 for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
739 and CIFS Packet Signing enablement.
743 Replace call to sleep_on with safer wait_on_event.
744 Make stylistic changes to better match kernel style recommendations.
745 Remove most typedef usage (except for the PDUs themselves).
749 Update mount so the -unc mount option is no longer required (the ip address can be specified
750 in a UNC style device name. Implementation of readpage/writepage started.
754 Fix intermittent problem with incorrect smb header checking on badly
755 fragmented tcp responses
759 Fixes to setting of allocation size and file size.
763 Various 2.5.38 fixes. Now works on 2.5.38
767 Prepare for 2.5 kernel merge. Remove ifdefs.
771 Socket buffer management fixes. Fix dual free.
775 Various big endian fixes for hardlinks and symlinks and also for dfs.
779 Various big endian fixes for servers with Unix extensions such as Samba
783 Various FindNext fixes for incorrect filenames on large directory searches on big endian
784 clients. basic posix file i/o tests now work on big endian machines, not just le
788 SessionSetup and NegotiateProtocol now work from Big Endian machines.
789 Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older
790 versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7).
794 Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
795 files now return the correct number of links on fstat as they are repeatedly linked and unlinked.
799 Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
800 session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
801 Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
802 (which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).
806 Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
807 it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
811 Rewrote much of connection and mount/unmount logic to handle bugs with
812 multiple uses to same share, multiple users to same server etc.
816 Fixed major problem with dentry corruption (missing call to dput)
820 Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
821 Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
822 although corresponding function not fully implemented in the vfs yet
826 Fixed dentry caching bug, misc. cleanup
830 Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
831 on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
832 Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
836 Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
837 and tested against Samba 2.2.5
842 1) Fixed lockrange to be correct (it was one byte too short)
844 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
845 show range as locked when there is a conflict with an existing lock.
847 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
848 in most cases. Eventually will offer optional ability to query server for the correct perms.
850 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
851 but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
854 4) Fixed error logging of valid mount options
856 5) Removed logging of password field.
858 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
859 and cleaned them up and made them more consistent with other cifs functions.
861 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
862 (with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
863 nor is the symlink support using the Unix extensions
865 8) Started adding the readlink and follow_link code
