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