3 Fix NTLMv2 signing. NFS server mounted over cifs works (if cifs mount is
4 done with "serverino" mount option). Add support for POSIX Unlink
5 (helps with certain sharing violation cases when server such as
6 Samba supports newer POSIX CIFS Protocol Extensions). Add "nounix"
7 mount option to allow disabling the CIFS Unix Extensions for just
8 that mount. Fix hang on spinlock in find_writable_file (race when
9 reopening file after session crash). Byte range unlock request to
10 windows server could unlock more bytes (on server copy of file)
11 than intended if start of unlock request is well before start of
12 a previous byte range lock that we issued.
16 IPv6 support. Enable ipv6 addresses to be passed on mount (put the ipv6
17 address after the "ip=" mount option, at least until mount.cifs is fixed to
18 handle DNS host to ipv6 name translation). Accept override of uid or gid
19 on mount even when Unix Extensions are negotiated (it used to be ignored
20 when Unix Extensions were ignored). This allows users to override the
21 default uid and gid for files when they are certain that the uids or
22 gids on the server do not match those of the client. Make "sec=none"
23 mount override username (so that null user connection is attempted)
24 to match what documentation said. Support for very large reads, over 127K,
25 available to some newer servers (such as Samba 3.0.26 and later but
26 note that it also requires setting CIFSMaxBufSize at module install
27 time to a larger value which may hurt performance in some cases).
28 Make sign option force signing (or fail if server does not support it).
32 Fix mtime bouncing around from local idea of last write times to remote time.
33 Fix hang (in i_size_read) when simultaneous size update of same remote file
34 on smp system corrupts sequence number. Do not reread unnecessarily partial page
35 (which we are about to overwrite anyway) when writing out file opened rw.
36 When DOS attribute of file on non-Unix server's file changes on the server side
37 from read-only back to read-write, reflect this change in default file mode
38 (we had been leaving a file's mode read-only until the inode were reloaded).
39 Allow setting of attribute back to ATTR_NORMAL (removing readonly dos attribute
40 when archive dos attribute not set and we are changing mode back to writeable
41 on server which does not support the Unix Extensions). Remove read only dos
42 attribute on chmod when adding any write permission (ie on any of
43 user/group/other (not all of user/group/other ie 0222) when
44 mounted to windows. Add support for POSIX MkDir (slight performance
45 enhancement and eliminates the network race between the mkdir and set
46 path info of the mode).
51 Fix oops in list_del during mount caused by unaligned string.
52 Fix file corruption which could occur on some large file
53 copies caused by writepages page i/o completion bug.
54 Seek to SEEK_END forces check for update of file size for non-cached
55 files. Allow file size to be updated on remote extend of locally open,
56 non-cached file. Fix reconnect to newer Samba servers (or other servers
57 which support the CIFS Unix/POSIX extensions) so that we again tell the
58 server the Unix/POSIX cifs capabilities which we support (SetFSInfo).
59 Add experimental support for new POSIX Open/Mkdir (which returns
60 stat information on the open, and allows setting the mode).
64 Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
65 Allow null user to be specified on mount ("username="). Do not return
66 EINVAL on readdir when filldir fails due to overwritten blocksize
67 (fixes FC problem). Return error in rename 2nd attempt retry (ie report
68 if rename by handle also fails, after rename by path fails, we were
69 not reporting whether the retry worked or not). Fix NTLMv2 to
70 work to Windows servers (mount with option "sec=ntlmv2").
74 Do not time out lockw calls when using posix extensions. Do not
75 time out requests if server still responding reasonably fast
76 on requests on other threads. Improve POSIX locking emulation,
77 (lock cancel now works, and unlock of merged range works even
78 to Windows servers now). Fix oops on mount to lanman servers
79 (win9x, os/2 etc.) when null password. Do not send listxattr
80 (SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
81 problem (instantiate inodes/dentries in right order for readdir).
85 Rewritten sessionsetup support, including support for legacy SMB
86 session setup needed for OS/2 and older servers such as Windows 95 and 98.
87 Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
88 so we can do search (ls etc.) to OS/2. Do not send NTCreateX
89 or recent levels of FindFirst unless server says it supports NT SMBs
90 (instead use legacy equivalents from LANMAN dialect). Fix to allow
91 NTLMv2 authentication support (now can use stronger password hashing
92 on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
93 Allow override of global cifs security flags on mount via "sec=" option(s).
97 POSIX locking to servers which support CIFS POSIX Extensions
98 (disabled by default controlled by proc/fs/cifs/Experimental).
99 Handle conversion of long share names (especially Asian languages)
100 to Unicode during mount. Fix memory leak in sess struct on reconnect.
101 Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
102 cifs open which helps rare case when setpathinfo fails or server does
107 Fix slow oplock break when mounted to different servers at the same time and
108 the tids match and we try to find matching fid on wrong server. Fix read
109 looping when signing required by server (2.6.16 kernel only). Fix readdir
110 vs. rename race which could cause each to hang. Return . and .. even
111 if server does not. Allow searches to skip first three entries and
112 begin at any location. Fix oops in find_writeable_file.
116 Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
117 configure stronger authentication. Fix sfu symlinks so they can
118 be followed (not just recognized). Fix wraparound of bcc on
119 read responses when buffer size over 64K and also fix wrap of
120 max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
121 cifs_user_read and cifs_readpages (when EAGAIN on send of smb
122 on socket is returned over and over). Add POSIX (advisory) byte range
123 locking support (requires server with newest CIFS UNIX Extensions
124 to the protocol implemented). Slow down negprot slightly in port 139
125 RFC1001 case to give session_init time on buggy servers.
129 Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
130 of readpages by eliminating one extra memcpy. Allow update of file size
131 from remote server even if file is open for write as long as mount is
132 directio. Recognize share mode security and send NTLM encrypted password
133 on tree connect if share mode negotiated.
137 Defer close of a file handle slightly if pending writes depend on that handle
138 (this reduces the EBADF bad file handle errors that can be logged under heavy
139 stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
140 Fix SFU style symlinks and mknod needed for servers which do not support the
141 CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
142 dentries so files that the client sees as deleted but that later get created
143 on the server will be recognized. Add client side permission check on setattr.
144 Timeout stuck requests better (where server has never responded or sent corrupt
149 Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
150 to be smaller at first (but increasing) so large write performance performance
151 over GigE is better. Do not hang thread on illegal byte range lock response
152 from Windows (Windows can send an RFC1001 size which does not match smb size) by
153 allowing an SMBs TCP length to be up to a few bytes longer than it should be.
154 wsize and rsize can now be larger than negotiated buffer size if server
155 supports large readx/writex, even when directio mount flag not specified.
156 Write size will in many cases now be 16K instead of 4K which greatly helps
157 file copy performance on lightly loaded networks. Fix oops in dnotify
158 when experimental config flag enabled. Make cifsFYI more granular.
162 Fix readdir caching when unlink removes file in current search buffer,
163 and this is followed by a rewind search to just before the deleted entry.
164 Do not attempt to set ctime unless atime and/or mtime change requested
165 (most servers throw it away anyway). Fix length check of received smbs
166 to be more accurate. Fix big endian problem with mapchars mount option,
167 and with a field returned by statfs.
171 Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
172 For these older servers, add option for passing netbios name of server in
173 on mount (servernetbiosname). Add suspend support for power management, to
174 avoid cifsd thread preventing software suspend from working.
175 Add mount option for disabling the default behavior of sending byte range lock
176 requests to the server (necessary for certain applications which break with
177 mandatory lock behavior such as Evolution), and also mount option for
178 requesting case insensitive matching for path based requests (requesting
179 case sensitive is the default).
183 Add writepage performance improvements. Fix path name conversions
184 for long filenames on mounts which were done with "mapchars" mount option
185 specified. Ensure multiplex ids do not collide. Fix case in which
186 rmmod can oops if done soon after last unmount. Fix truncated
187 search (readdir) output when resume filename was a long filename.
188 Fix filename conversion when mapchars mount option was specified and
189 filename was a long filename.
193 Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
194 Do not oops if root user kills cifs oplock kernel thread or
195 kills the cifsd thread (NB: killing the cifs kernel threads is not
196 recommended, unmount and rmmod cifs will kill them when they are
197 no longer needed). Fix readdir to ASCII servers (ie older servers
198 which do not support Unicode) and also require asterisk.
199 Fix out of memory case in which data could be written one page
200 off in the page cache.
204 Fix caching problem, in which readdir of directory containing a file
205 which was cached could cause the file's time stamp to be updated
206 without invalidating the readahead data (so we could get stale
207 file data on the client for that file even as the server copy changed).
208 Cleanup response processing so cifsd can not loop when abnormally
214 Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
215 transact response for an SMB request and search entry split across two frames.
216 Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
217 as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
218 unless server explicitly claims to support them in CIFS Unix extensions
219 POSIX ACL capability bit. Fix packet signing when multiuser mounting with
220 different users from the same client to the same server. Fix oops in
221 cifs_close. Add mount option for remapping reserved characters in
222 filenames (also allow recognizing files with created by SFU which have any
223 of these seven reserved characters, except backslash, to be recognized).
224 Fix invalid transact2 message (we were sometimes trying to interpret
225 oplock breaks as SMB responses). Add ioctl for checking that the
226 current uid matches the uid of the mounter (needed by umount.cifs).
227 Reduce the number of large buffer allocations in cifs response processing
228 (significantly reduces memory pressure under heavy stress with multiple
229 processes accessing the same server at the same time).
233 Fix updates of DOS attributes and time fields so that files on NT4 servers
234 do not get marked delete on close. Display sizes of cifs buffer pools in
235 cifs stats. Fix oops in unmount when cifsd thread being killed by
236 shutdown. Add generic readv/writev and aio support. Report inode numbers
237 consistently in readdir and lookup (when serverino mount option is
238 specified use the inode number that the server reports - for both lookup
239 and readdir, otherwise by default the locally generated inode number is used
240 for inodes created in either path since servers are not always able to
241 provide unique inode numbers when exporting multiple volumes from under one
246 Allow new nouser_xattr mount parm to disable xattr support for user namespace.
247 Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
248 (mostly affects NT4 servers) by retry with handle based network operation.
249 Add new POSIX Query FS Info for returning statfs info more accurately.
250 Handle passwords with multiple commas in them.
254 Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
255 Fix capabilities flags for large readx so as to allow reads larger than 64K.
259 Add module init parm for large SMB buffer size (to allow it to be changed
260 from its default of 16K) which is especially useful for large file copy
261 when mounting with the directio mount option. Fix oops after
262 returning from mount when experimental ExtendedSecurity enabled and
263 SpnegoNegotiated returning invalid error. Fix case to retry better when
264 peek returns from 1 to 3 bytes on socket which should have more data.
265 Fixed path based calls (such as cifs lookup) to handle path names
266 longer than 530 (now can handle PATH_MAX). Fix pass through authentication
267 from Samba server to DC (Samba required dummy LM password).
271 Turn off DNOTIFY (directory change notification support) by default
272 (unless built with the experimental flag) to fix hang with KDE
273 file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
274 waiting on an SMB response) in SendReceive when session dies but
275 reconnects quickly from another task. Add module init parms for
276 minimum number of large and small network buffers in the buffer pools,
277 and for the maximum number of simultaneous requests.
281 Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
282 and other POSIX CIFS compliant servers. Fix error mapping for getfacl
283 to EOPNOTSUPP when server does not support posix acls on the wire. Fix
284 improperly zeroed buffer in CIFS Unix extensions set times call.
288 Fix internationalization problem in cifs readdir with filenames that map to
289 longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
290 for readdir to netapp servers. Fix search rewind (seek into readdir to return
291 non-consecutive entries). Do not do readdir when server negotiates
292 buffer size to small to fit filename. Add support for reading POSIX ACLs from
293 the server (add also acl and noacl mount options).
297 Optionally allow using server side inode numbers, rather than client generated
298 ones by specifying mount option "serverino" - this is required for some apps
299 to work which double check hardlinked files and have persistent inode numbers.
303 Multiple bigendian fixes. On little endian systems (for reconnect after
304 network failure) fix tcp session reconnect code so we do not try first
305 to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
306 as directories rather than symlinks because we can do follow link on them.
310 Add config option to enable XATTR (extended attribute) support, mapping
311 xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
312 minor fixes pointed out by the Stanford SWAT checker (mostly missing
313 or out of order NULL pointer checks in little used error paths).
317 Add new mount parm to control whether mode check (generic_permission) is done
318 on the client. If Unix extensions are enabled and the uids on the client
319 and server do not match, client permission checks are meaningless on
320 server uids that do not exist on the client (this does not affect the
321 normal ACL check which occurs on the server). Fix default uid
322 on mknod to match create and mkdir. Add optional mount parm to allow
323 override of the default uid behavior (in which the server sets the uid
324 and gid of newly created files). Normally for network filesystem mounts
325 user want the server to set the uid/gid on newly created files (rather than
326 using uid of the client processes you would in a local filesystem).
330 Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
331 info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
332 (in build_wildcard_path_from_dentry). Fix mknod to pass type field
333 (block/char/fifo) properly. Remove spurious mount warning log entry when
334 credentials passed as mount argument. Set major/minor device number in
335 inode for block and char devices when unix extensions enabled.
339 Fix /proc/fs/cifs/Stats and DebugData display to handle larger
340 amounts of return data. Properly limit requests to MAX_REQ (50
341 is the usual maximum active multiplex SMB/CIFS requests per server).
342 Do not kill cifsd (and thus hurt the other SMB session) when more than one
343 session to the same server (but with different userids) exists and one
344 of the two user's smb sessions is being removed while leaving the other.
345 Do not loop reconnecting in cifsd demultiplex thread when admin
346 kills the thread without going through unmount.
350 Do not rename hardlinked files (since that should be a noop). Flush
351 cached write behind data when reopening a file after session abend,
352 except when already in write. Grab per socket sem during reconnect
353 to avoid oops in sendmsg if overlapping with reconnect. Do not
354 reset cached inode file size on readdir for files open for write on
360 Update number of blocks in file so du command is happier (in Linux a fake
361 blocksize of 512 is required for calculating number of blocks in inode).
362 Fix prepare write of partial pages to read in data from server if possible.
363 Fix race on tcpStatus field between unmount and reconnection code, causing
364 cifsd process sometimes to hang around forever. Improve out of memory
365 checks in cifs_filldir
369 Fix incorrect file size in file handle based setattr on big endian hardware.
370 Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
371 and closing file structs in writepage/partialpagewrite. Add statistics
372 for each mounted share (new menuconfig option). Fix endianness problem in
373 volume information displayed in /proc/fs/cifs/DebugData (only affects
374 affects big endian architectures). Prevent renames while constructing
375 path names for open, mkdir and rmdir.
379 Change to mempools for alloc smb request buffers and multiplex structs
380 to better handle low memory problems (and potential deadlocks).
384 Fix incomplete listings of large directories on Samba servers when Unix
385 extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
386 rename deadlock when writing out dirty pages at same time.
390 Fix open of files in which O_CREATE can cause the mode to change in
391 some cases. Fix case in which retry of write overlaps file close.
392 Fix PPC64 build error. Reduce excessive stack usage in smb password
393 hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
397 Fixes for large file copy, signal handling, socket retry, buffer
398 allocation and low memory situations.
402 Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
403 also now allowing support for specifying client netbiosname. NT4 support added.
407 Fix reconnection (and certain failed mounts) to properly wake up the
408 blocked users thread so it does not seem hung (in some cases was blocked
409 until the cifs receive timeout expired). Fix spurious error logging
410 to kernel log when application with open network files killed.
414 Fix /proc/fs module unload warning message (that could be logged
415 to the kernel log). Fix intermittent failure in connectathon
416 test7 (hardlink count not immediately refreshed in case in which
417 inode metadata can be incorrectly kept cached when time near zero)
421 Allow file_mode and dir_mode (specified at mount time) to be enforced
422 locally (the server already enforced its own ACLs too) for servers
423 that do not report the correct mode (do not support the
424 CIFS Unix Extensions).
428 Fix some small memory leaks in some unmount error paths. Fix major leak
429 of cache pages in readpages causing multiple read oriented stress
430 testcases (including fsx, and even large file copy) to fail over time.
434 Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
435 This allows files that differ only in case and improves performance of file
436 creation and file open to such servers. Fix semaphore conflict which causes
437 slow delete of open file to Samba (which unfortunately can cause an oplock
438 break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
442 fixes to cifs_readpages for fsx test case
446 Fix caching data integrity bug when extending file size especially when no
447 oplock on file. Fix spurious logging of valid already parsed mount options
448 that are parsed outside of the cifs vfs such as nosuid.
453 Connect to server when port number override not specified, and tcp port
454 unitialized. Reset search to restart at correct file when kernel routine
455 filldir returns error during large directory searches (readdir).
459 Fix caching problem when files opened by multiple clients in which
460 page cache could contain stale data, and write through did
461 not occur often enough while file was still open when read ahead
462 (read oplock) not allowed. Treat "sep=" when first mount option
463 as an override of comma as the default separator between mount
468 Allow passwords longer than 16 bytes. Allow null password string.
472 Gracefully clean up failed mounts when attempting to mount to servers such as
473 Windows 98 that terminate tcp sessions during protocol negotiation. Handle
474 embedded commas in mount parsing of passwords.
478 Invalidate local inode cached pages on oplock break and when last file
479 instance is closed so that the client does not continue using stale local
480 copy rather than later modified server copy of file. Do not reconnect
481 when server drops the tcp session prematurely before negotiate
482 protocol response. Fix oops in reopen_file when dentry freed. Allow
483 the support for CIFS Unix Extensions to be disabled via proc interface.
487 Fix hang in commit_write during reconnection of open files under heavy load.
488 Fix unload_nls oops in a mount failure path. Serialize writes to same socket
489 which also fixes any possible races when cifs signatures are enabled in SMBs
490 being sent out of signature sequence number order.
494 Fix byte range locking bug (endian problem) causing bad offset and
499 Fix oops (in send_sig) caused by CIFS unmount code trying to
500 wake up the demultiplex thread after it had exited. Do not log
501 error on harmless oplock release of closed handle.
505 Fix unsafe global variable usage and password hash failure on gcc 3.3.1
506 Fix problem reconnecting secondary mounts to same server after session
507 failure. Fix invalid dentry - race in mkdir when directory gets created
508 by another client between the lookup and mkdir.
512 Fix to list processing in reopen_files. Fix reconnection when server hung
513 but tcpip session still alive. Set proper timeout on socket read.
517 Add missing mount options including iocharset. SMP fixes in write and open.
518 Fix errors in reconnecting after TCP session failure. Fix module unloading
519 of default nls codepage
523 Active smb transactions should never go negative (fix double FreeXid). Fix
524 list processing in file routines. Check return code on kmalloc in open.
525 Fix spinlock usage for SMP.
529 Fix oops in reopen_files when invalid dentry. drop dentry on server rename
530 and on revalidate errors. Fix cases where pid is now tgid. Fix return code
531 on create hard link when server does not support them.
535 Fix scheduling while atomic error in getting inode info on newly created file.
536 Fix truncate of existing files opened with O_CREAT but not O_TRUNC set.
540 Fix oops on write to dead tcp session. Remove error log write for case when file open
541 O_CREAT but not O_EXCL
545 Fix non-POSIX behavior on rename of open file and delete of open file by taking
546 advantage of trans2 SetFileInfo rename facility if available on target server.
547 Retry on ENOSPC and EAGAIN socket errors.
551 Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix
552 allocation size miscalculation. After oplock token lost do not read through
557 Fix oops on empty file readahead. Fix for file size handling for locally cached files.
561 Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files
562 during auto reconnection to server after server recovered from failure.
566 Finish support for Linux 2.5 open/create changes, which removes the
567 redundant NTCreate/QPathInfo/close that was sent during file create.
568 Enable oplock by default. Enable packet signing by default (needed to
569 access many recent Windows servers)
573 Fix oops when mounting to long server names caused by inverted parms to kmalloc.
574 Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
575 we will choose a cifs user session (smb uid) that better matches the local
576 uid if a) the mount uid does not match the current uid and b) we have another
577 session to the same server (ip address) for a different mount which
578 matches the current local uid.
582 Add support for mknod of block or character devices. Fix oplock
583 code (distributed caching) to properly send response to oplock
588 Finish up CIFS packet digital signing for the default
589 NTLM security case. This should help Windows 2003
590 network interoperability since it is common for
591 packet signing to be required now. Fix statfs (stat -f)
592 which recently started returning errors due to
593 invalid value (-1 instead of 0) being set in the
594 struct kstatfs f_ffiles field.
598 Fix oops on stopping oplock thread when removing cifs when
603 Fix mount options for ro (readonly), uid, gid and file and directory mode.
607 Fix errors displayed on failed mounts to be more understandable.
608 Fixed various incorrect or misleading smb to posix error code mappings.
612 Fix display of NTFS DFS junctions to display as symlinks.
613 They are the network equivalent. Fix oops in
614 cifs_partialpagewrite caused by missing spinlock protection
615 of openfile linked list. Allow writebehind caching errors to
616 be returned to the application at file close.
620 Clean up options displayed in /proc/mounts by show_options to
621 be more consistent with other filesystems.
625 Fix delete of readonly file to Windows servers. Reflect
626 presence or absence of read only dos attribute in mode
627 bits for servers that do not support CIFS Unix extensions.
628 Fix shortened results on readdir of large directories to
629 servers supporting CIFS Unix extensions (caused by
630 incorrect resume key).
634 Fix truncate bug (set file size) that could cause hangs e.g. running fsx
638 unload nls if mount fails.
642 Add resume key support to search (readdir) code to workaround
643 Windows bug. Add /proc/fs/cifs/LookupCacheEnable which
644 allows disabling caching of attribute information for
649 Add more oplock handling (distributed caching code). Remove
650 dead code. Remove excessive stack space utilization from
655 Fix oops in get dfs referral (triggered when null path sent in to
656 mount). Add support for overriding rsize at mount time.
660 Fix buffer overrun in readdir which caused intermittent kernel oopses.
661 Fix writepage code to release kmap on write data. Allow "-ip=" new
662 mount option to be passed in on parameter distinct from the first part
663 (server name portion of) the UNC name. Allow override of the
664 tcp port of the target server via new mount option "-port="
668 Fix search handle leak on rewind. Fix setuid and gid so that they are
669 reflected in the local inode immediately. Cleanup of whitespace
670 to make 2.4 and 2.5 versions more consistent.
675 Fix signal sending so that captive thread (cifsd) exits on umount
676 (which was causing the warning in kmem_cache_free of the request buffers
677 at rmmod time). This had broken as a sideeffect of the recent global
678 kernel change to daemonize. Fix memory leak in readdir code which
679 showed up in "ls -R" (and applications that did search rewinding).
683 Reconnect tids and fids after session reconnection (still do not
684 reconnect byte range locks though). Fix problem caching
685 lookup information for directory inodes, improving performance,
686 especially in deep directory trees. Fix various build warnings.
690 Finish fixes to commit write for caching/readahead consistency. fsx
691 now works to Samba servers. Fix oops caused when readahead
692 was interrupted by a signal.
696 Fix data corruption (in partial page after truncate) that caused fsx to
697 fail to Windows servers. Cleaned up some extraneous error logging in
698 common error paths. Add generic sendfile support.
702 Fix memory leak in AllocMidQEntry.
703 Finish reconnection logic, so connection with server can be dropped
704 (or server rebooted) and the cifs client will reconnect.
708 Fix temporary socket leak when bad userid or password specified
709 (or other SMBSessSetup failure). Increase maximum buffer size to slightly
710 over 16K to allow negotiation of up to Samba and Windows server default read
711 sizes. Add support for readpages
715 Fix oops when username not passed in on mount. Extensive fixes and improvements
716 to error logging (strip redundant newlines, change debug macros to ensure newline
717 passed in and to be more consistent). Fix writepage wrong file handle problem,
718 a readonly file handle could be incorrectly used to attempt to write out
719 file updates through the page cache to multiply open files. This could cause
720 the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
721 shares to the same Windows server when using different usernames
722 (doing this to Samba servers worked but Windows was rejecting it) - now it is
723 possible to use different userids when connecting to the same server from a
724 Linux client. Fix oops when treeDisconnect called during unmount on
725 previously freed socket.
729 Fix oops in readpages caused by not setting address space operations in inode in
734 Includes support for deleting of open files and renaming over existing files (per POSIX
735 requirement). Add readlink support for Windows junction points (directory symlinks).
739 Changed read and write to go through pagecache. Added additional address space operations.
740 Memory mapped operations now working.
744 Added writepage code for additional memory mapping support. Fixed leak in xids causing
745 the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
746 every stat call. Additional formatting cleanup.
750 Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
754 Fixes from Zwane Mwaikambo for adding missing return code checking in a few places.
755 Also included a modified version of his fix to protect global list manipulation of
756 the smb session and tree connection and mid related global variables.
760 Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
761 changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
762 buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
766 More stylistic updates to better match kernel style. Add additional statistics
767 for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
768 and CIFS Packet Signing enablement.
772 Replace call to sleep_on with safer wait_on_event.
773 Make stylistic changes to better match kernel style recommendations.
774 Remove most typedef usage (except for the PDUs themselves).
778 Update mount so the -unc mount option is no longer required (the ip address can be specified
779 in a UNC style device name. Implementation of readpage/writepage started.
783 Fix intermittent problem with incorrect smb header checking on badly
784 fragmented tcp responses
788 Fixes to setting of allocation size and file size.
792 Various 2.5.38 fixes. Now works on 2.5.38
796 Prepare for 2.5 kernel merge. Remove ifdefs.
800 Socket buffer management fixes. Fix dual free.
804 Various big endian fixes for hardlinks and symlinks and also for dfs.
808 Various big endian fixes for servers with Unix extensions such as Samba
812 Various FindNext fixes for incorrect filenames on large directory searches on big endian
813 clients. basic posix file i/o tests now work on big endian machines, not just le
817 SessionSetup and NegotiateProtocol now work from Big Endian machines.
818 Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older
819 versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7).
823 Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
824 files now return the correct number of links on fstat as they are repeatedly linked and unlinked.
828 Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
829 session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
830 Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
831 (which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).
835 Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
836 it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
840 Rewrote much of connection and mount/unmount logic to handle bugs with
841 multiple uses to same share, multiple users to same server etc.
845 Fixed major problem with dentry corruption (missing call to dput)
849 Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
850 Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
851 although corresponding function not fully implemented in the vfs yet
855 Fixed dentry caching bug, misc. cleanup
859 Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
860 on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
861 Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
865 Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
866 and tested against Samba 2.2.5
871 1) Fixed lockrange to be correct (it was one byte too short)
873 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
874 show range as locked when there is a conflict with an existing lock.
876 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
877 in most cases. Eventually will offer optional ability to query server for the correct perms.
879 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
880 but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
883 4) Fixed error logging of valid mount options
885 5) Removed logging of password field.
887 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
888 and cleaned them up and made them more consistent with other cifs functions.
890 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
891 (with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
892 nor is the symlink support using the Unix extensions
894 8) Started adding the readlink and follow_link code
