3 Fix oops on second mount to server when null auth is used.
4 Enable experimental Kerberos support. Return writebehind errors on flush
5 and sync so that events like out of disk space get reported properly on
6 cached files. Fix setxattr failure to certain Samba versions. Fix mount
7 of second share to disconnected server session (autoreconnect on this).
8 Add ability to modify cifs acls for handling chmod (when mounted with
9 cifsacl flag). Fix prefixpath path separator so we can handle mounts
10 with prefixpaths longer than one directory (one path component) when
11 mounted to Windows servers. Fix slow file open when cifsacl
16 Fix memory leak in statfs when mounted to very old servers (e.g.
17 Windows 9x). Add new feature "POSIX open" which allows servers
18 which support the current POSIX Extensions to provide better semantics
19 (e.g. delete for open files opened with posix open). Take into
20 account umask on posix mkdir not just older style mkdir. Add
21 ability to mount to IPC$ share (which allows CIFS named pipes to be
22 opened, read and written as if they were files). When 1st tree
23 connect fails (e.g. due to signing negotiation failure) fix
24 leak that causes cifsd not to stop and rmmod to fail to cleanup
25 cifs_request_buffers pool. Fix problem with POSIX Open/Mkdir on
26 bigendian architectures. Fix possible memory corruption when
27 EAGAIN returned on kern_recvmsg. Return better error if server
28 requires packet signing but client has disabled it. When mounted
29 with cifsacl mount option - mode bits are approximated based
30 on the contents of the ACL of the file or directory. When cifs
31 mount helper is missing convert make sure that UNC name
32 has backslash (not forward slash) between ip address of server
37 Fix NTLMv2 signing. NFS server mounted over cifs works (if cifs mount is
38 done with "serverino" mount option). Add support for POSIX Unlink
39 (helps with certain sharing violation cases when server such as
40 Samba supports newer POSIX CIFS Protocol Extensions). Add "nounix"
41 mount option to allow disabling the CIFS Unix Extensions for just
42 that mount. Fix hang on spinlock in find_writable_file (race when
43 reopening file after session crash). Byte range unlock request to
44 windows server could unlock more bytes (on server copy of file)
45 than intended if start of unlock request is well before start of
46 a previous byte range lock that we issued.
50 IPv6 support. Enable ipv6 addresses to be passed on mount (put the ipv6
51 address after the "ip=" mount option, at least until mount.cifs is fixed to
52 handle DNS host to ipv6 name translation). Accept override of uid or gid
53 on mount even when Unix Extensions are negotiated (it used to be ignored
54 when Unix Extensions were ignored). This allows users to override the
55 default uid and gid for files when they are certain that the uids or
56 gids on the server do not match those of the client. Make "sec=none"
57 mount override username (so that null user connection is attempted)
58 to match what documentation said. Support for very large reads, over 127K,
59 available to some newer servers (such as Samba 3.0.26 and later but
60 note that it also requires setting CIFSMaxBufSize at module install
61 time to a larger value which may hurt performance in some cases).
62 Make sign option force signing (or fail if server does not support it).
66 Fix mtime bouncing around from local idea of last write times to remote time.
67 Fix hang (in i_size_read) when simultaneous size update of same remote file
68 on smp system corrupts sequence number. Do not reread unnecessarily partial page
69 (which we are about to overwrite anyway) when writing out file opened rw.
70 When DOS attribute of file on non-Unix server's file changes on the server side
71 from read-only back to read-write, reflect this change in default file mode
72 (we had been leaving a file's mode read-only until the inode were reloaded).
73 Allow setting of attribute back to ATTR_NORMAL (removing readonly dos attribute
74 when archive dos attribute not set and we are changing mode back to writeable
75 on server which does not support the Unix Extensions). Remove read only dos
76 attribute on chmod when adding any write permission (ie on any of
77 user/group/other (not all of user/group/other ie 0222) when
78 mounted to windows. Add support for POSIX MkDir (slight performance
79 enhancement and eliminates the network race between the mkdir and set
80 path info of the mode).
85 Fix oops in list_del during mount caused by unaligned string.
86 Fix file corruption which could occur on some large file
87 copies caused by writepages page i/o completion bug.
88 Seek to SEEK_END forces check for update of file size for non-cached
89 files. Allow file size to be updated on remote extend of locally open,
90 non-cached file. Fix reconnect to newer Samba servers (or other servers
91 which support the CIFS Unix/POSIX extensions) so that we again tell the
92 server the Unix/POSIX cifs capabilities which we support (SetFSInfo).
93 Add experimental support for new POSIX Open/Mkdir (which returns
94 stat information on the open, and allows setting the mode).
98 Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
99 Allow null user to be specified on mount ("username="). Do not return
100 EINVAL on readdir when filldir fails due to overwritten blocksize
101 (fixes FC problem). Return error in rename 2nd attempt retry (ie report
102 if rename by handle also fails, after rename by path fails, we were
103 not reporting whether the retry worked or not). Fix NTLMv2 to
104 work to Windows servers (mount with option "sec=ntlmv2").
108 Do not time out lockw calls when using posix extensions. Do not
109 time out requests if server still responding reasonably fast
110 on requests on other threads. Improve POSIX locking emulation,
111 (lock cancel now works, and unlock of merged range works even
112 to Windows servers now). Fix oops on mount to lanman servers
113 (win9x, os/2 etc.) when null password. Do not send listxattr
114 (SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
115 problem (instantiate inodes/dentries in right order for readdir).
119 Rewritten sessionsetup support, including support for legacy SMB
120 session setup needed for OS/2 and older servers such as Windows 95 and 98.
121 Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
122 so we can do search (ls etc.) to OS/2. Do not send NTCreateX
123 or recent levels of FindFirst unless server says it supports NT SMBs
124 (instead use legacy equivalents from LANMAN dialect). Fix to allow
125 NTLMv2 authentication support (now can use stronger password hashing
126 on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
127 Allow override of global cifs security flags on mount via "sec=" option(s).
131 POSIX locking to servers which support CIFS POSIX Extensions
132 (disabled by default controlled by proc/fs/cifs/Experimental).
133 Handle conversion of long share names (especially Asian languages)
134 to Unicode during mount. Fix memory leak in sess struct on reconnect.
135 Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
136 cifs open which helps rare case when setpathinfo fails or server does
141 Fix slow oplock break when mounted to different servers at the same time and
142 the tids match and we try to find matching fid on wrong server. Fix read
143 looping when signing required by server (2.6.16 kernel only). Fix readdir
144 vs. rename race which could cause each to hang. Return . and .. even
145 if server does not. Allow searches to skip first three entries and
146 begin at any location. Fix oops in find_writeable_file.
150 Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
151 configure stronger authentication. Fix sfu symlinks so they can
152 be followed (not just recognized). Fix wraparound of bcc on
153 read responses when buffer size over 64K and also fix wrap of
154 max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
155 cifs_user_read and cifs_readpages (when EAGAIN on send of smb
156 on socket is returned over and over). Add POSIX (advisory) byte range
157 locking support (requires server with newest CIFS UNIX Extensions
158 to the protocol implemented). Slow down negprot slightly in port 139
159 RFC1001 case to give session_init time on buggy servers.
163 Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
164 of readpages by eliminating one extra memcpy. Allow update of file size
165 from remote server even if file is open for write as long as mount is
166 directio. Recognize share mode security and send NTLM encrypted password
167 on tree connect if share mode negotiated.
171 Defer close of a file handle slightly if pending writes depend on that handle
172 (this reduces the EBADF bad file handle errors that can be logged under heavy
173 stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
174 Fix SFU style symlinks and mknod needed for servers which do not support the
175 CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
176 dentries so files that the client sees as deleted but that later get created
177 on the server will be recognized. Add client side permission check on setattr.
178 Timeout stuck requests better (where server has never responded or sent corrupt
183 Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
184 to be smaller at first (but increasing) so large write performance performance
185 over GigE is better. Do not hang thread on illegal byte range lock response
186 from Windows (Windows can send an RFC1001 size which does not match smb size) by
187 allowing an SMBs TCP length to be up to a few bytes longer than it should be.
188 wsize and rsize can now be larger than negotiated buffer size if server
189 supports large readx/writex, even when directio mount flag not specified.
190 Write size will in many cases now be 16K instead of 4K which greatly helps
191 file copy performance on lightly loaded networks. Fix oops in dnotify
192 when experimental config flag enabled. Make cifsFYI more granular.
196 Fix readdir caching when unlink removes file in current search buffer,
197 and this is followed by a rewind search to just before the deleted entry.
198 Do not attempt to set ctime unless atime and/or mtime change requested
199 (most servers throw it away anyway). Fix length check of received smbs
200 to be more accurate. Fix big endian problem with mapchars mount option,
201 and with a field returned by statfs.
205 Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
206 For these older servers, add option for passing netbios name of server in
207 on mount (servernetbiosname). Add suspend support for power management, to
208 avoid cifsd thread preventing software suspend from working.
209 Add mount option for disabling the default behavior of sending byte range lock
210 requests to the server (necessary for certain applications which break with
211 mandatory lock behavior such as Evolution), and also mount option for
212 requesting case insensitive matching for path based requests (requesting
213 case sensitive is the default).
217 Add writepage performance improvements. Fix path name conversions
218 for long filenames on mounts which were done with "mapchars" mount option
219 specified. Ensure multiplex ids do not collide. Fix case in which
220 rmmod can oops if done soon after last unmount. Fix truncated
221 search (readdir) output when resume filename was a long filename.
222 Fix filename conversion when mapchars mount option was specified and
223 filename was a long filename.
227 Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
228 Do not oops if root user kills cifs oplock kernel thread or
229 kills the cifsd thread (NB: killing the cifs kernel threads is not
230 recommended, unmount and rmmod cifs will kill them when they are
231 no longer needed). Fix readdir to ASCII servers (ie older servers
232 which do not support Unicode) and also require asterisk.
233 Fix out of memory case in which data could be written one page
234 off in the page cache.
238 Fix caching problem, in which readdir of directory containing a file
239 which was cached could cause the file's time stamp to be updated
240 without invalidating the readahead data (so we could get stale
241 file data on the client for that file even as the server copy changed).
242 Cleanup response processing so cifsd can not loop when abnormally
248 Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
249 transact response for an SMB request and search entry split across two frames.
250 Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
251 as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
252 unless server explicitly claims to support them in CIFS Unix extensions
253 POSIX ACL capability bit. Fix packet signing when multiuser mounting with
254 different users from the same client to the same server. Fix oops in
255 cifs_close. Add mount option for remapping reserved characters in
256 filenames (also allow recognizing files with created by SFU which have any
257 of these seven reserved characters, except backslash, to be recognized).
258 Fix invalid transact2 message (we were sometimes trying to interpret
259 oplock breaks as SMB responses). Add ioctl for checking that the
260 current uid matches the uid of the mounter (needed by umount.cifs).
261 Reduce the number of large buffer allocations in cifs response processing
262 (significantly reduces memory pressure under heavy stress with multiple
263 processes accessing the same server at the same time).
267 Fix updates of DOS attributes and time fields so that files on NT4 servers
268 do not get marked delete on close. Display sizes of cifs buffer pools in
269 cifs stats. Fix oops in unmount when cifsd thread being killed by
270 shutdown. Add generic readv/writev and aio support. Report inode numbers
271 consistently in readdir and lookup (when serverino mount option is
272 specified use the inode number that the server reports - for both lookup
273 and readdir, otherwise by default the locally generated inode number is used
274 for inodes created in either path since servers are not always able to
275 provide unique inode numbers when exporting multiple volumes from under one
280 Allow new nouser_xattr mount parm to disable xattr support for user namespace.
281 Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
282 (mostly affects NT4 servers) by retry with handle based network operation.
283 Add new POSIX Query FS Info for returning statfs info more accurately.
284 Handle passwords with multiple commas in them.
288 Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
289 Fix capabilities flags for large readx so as to allow reads larger than 64K.
293 Add module init parm for large SMB buffer size (to allow it to be changed
294 from its default of 16K) which is especially useful for large file copy
295 when mounting with the directio mount option. Fix oops after
296 returning from mount when experimental ExtendedSecurity enabled and
297 SpnegoNegotiated returning invalid error. Fix case to retry better when
298 peek returns from 1 to 3 bytes on socket which should have more data.
299 Fixed path based calls (such as cifs lookup) to handle path names
300 longer than 530 (now can handle PATH_MAX). Fix pass through authentication
301 from Samba server to DC (Samba required dummy LM password).
305 Turn off DNOTIFY (directory change notification support) by default
306 (unless built with the experimental flag) to fix hang with KDE
307 file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
308 waiting on an SMB response) in SendReceive when session dies but
309 reconnects quickly from another task. Add module init parms for
310 minimum number of large and small network buffers in the buffer pools,
311 and for the maximum number of simultaneous requests.
315 Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
316 and other POSIX CIFS compliant servers. Fix error mapping for getfacl
317 to EOPNOTSUPP when server does not support posix acls on the wire. Fix
318 improperly zeroed buffer in CIFS Unix extensions set times call.
322 Fix internationalization problem in cifs readdir with filenames that map to
323 longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
324 for readdir to netapp servers. Fix search rewind (seek into readdir to return
325 non-consecutive entries). Do not do readdir when server negotiates
326 buffer size to small to fit filename. Add support for reading POSIX ACLs from
327 the server (add also acl and noacl mount options).
331 Optionally allow using server side inode numbers, rather than client generated
332 ones by specifying mount option "serverino" - this is required for some apps
333 to work which double check hardlinked files and have persistent inode numbers.
337 Multiple bigendian fixes. On little endian systems (for reconnect after
338 network failure) fix tcp session reconnect code so we do not try first
339 to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
340 as directories rather than symlinks because we can do follow link on them.
344 Add config option to enable XATTR (extended attribute) support, mapping
345 xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
346 minor fixes pointed out by the Stanford SWAT checker (mostly missing
347 or out of order NULL pointer checks in little used error paths).
351 Add new mount parm to control whether mode check (generic_permission) is done
352 on the client. If Unix extensions are enabled and the uids on the client
353 and server do not match, client permission checks are meaningless on
354 server uids that do not exist on the client (this does not affect the
355 normal ACL check which occurs on the server). Fix default uid
356 on mknod to match create and mkdir. Add optional mount parm to allow
357 override of the default uid behavior (in which the server sets the uid
358 and gid of newly created files). Normally for network filesystem mounts
359 user want the server to set the uid/gid on newly created files (rather than
360 using uid of the client processes you would in a local filesystem).
364 Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
365 info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
366 (in build_wildcard_path_from_dentry). Fix mknod to pass type field
367 (block/char/fifo) properly. Remove spurious mount warning log entry when
368 credentials passed as mount argument. Set major/minor device number in
369 inode for block and char devices when unix extensions enabled.
373 Fix /proc/fs/cifs/Stats and DebugData display to handle larger
374 amounts of return data. Properly limit requests to MAX_REQ (50
375 is the usual maximum active multiplex SMB/CIFS requests per server).
376 Do not kill cifsd (and thus hurt the other SMB session) when more than one
377 session to the same server (but with different userids) exists and one
378 of the two user's smb sessions is being removed while leaving the other.
379 Do not loop reconnecting in cifsd demultiplex thread when admin
380 kills the thread without going through unmount.
384 Do not rename hardlinked files (since that should be a noop). Flush
385 cached write behind data when reopening a file after session abend,
386 except when already in write. Grab per socket sem during reconnect
387 to avoid oops in sendmsg if overlapping with reconnect. Do not
388 reset cached inode file size on readdir for files open for write on
394 Update number of blocks in file so du command is happier (in Linux a fake
395 blocksize of 512 is required for calculating number of blocks in inode).
396 Fix prepare write of partial pages to read in data from server if possible.
397 Fix race on tcpStatus field between unmount and reconnection code, causing
398 cifsd process sometimes to hang around forever. Improve out of memory
399 checks in cifs_filldir
403 Fix incorrect file size in file handle based setattr on big endian hardware.
404 Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
405 and closing file structs in writepage/partialpagewrite. Add statistics
406 for each mounted share (new menuconfig option). Fix endianness problem in
407 volume information displayed in /proc/fs/cifs/DebugData (only affects
408 affects big endian architectures). Prevent renames while constructing
409 path names for open, mkdir and rmdir.
413 Change to mempools for alloc smb request buffers and multiplex structs
414 to better handle low memory problems (and potential deadlocks).
418 Fix incomplete listings of large directories on Samba servers when Unix
419 extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
420 rename deadlock when writing out dirty pages at same time.
424 Fix open of files in which O_CREATE can cause the mode to change in
425 some cases. Fix case in which retry of write overlaps file close.
426 Fix PPC64 build error. Reduce excessive stack usage in smb password
427 hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
431 Fixes for large file copy, signal handling, socket retry, buffer
432 allocation and low memory situations.
436 Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
437 also now allowing support for specifying client netbiosname. NT4 support added.
441 Fix reconnection (and certain failed mounts) to properly wake up the
442 blocked users thread so it does not seem hung (in some cases was blocked
443 until the cifs receive timeout expired). Fix spurious error logging
444 to kernel log when application with open network files killed.
448 Fix /proc/fs module unload warning message (that could be logged
449 to the kernel log). Fix intermittent failure in connectathon
450 test7 (hardlink count not immediately refreshed in case in which
451 inode metadata can be incorrectly kept cached when time near zero)
455 Allow file_mode and dir_mode (specified at mount time) to be enforced
456 locally (the server already enforced its own ACLs too) for servers
457 that do not report the correct mode (do not support the
458 CIFS Unix Extensions).
462 Fix some small memory leaks in some unmount error paths. Fix major leak
463 of cache pages in readpages causing multiple read oriented stress
464 testcases (including fsx, and even large file copy) to fail over time.
468 Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
469 This allows files that differ only in case and improves performance of file
470 creation and file open to such servers. Fix semaphore conflict which causes
471 slow delete of open file to Samba (which unfortunately can cause an oplock
472 break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
476 fixes to cifs_readpages for fsx test case
480 Fix caching data integrity bug when extending file size especially when no
481 oplock on file. Fix spurious logging of valid already parsed mount options
482 that are parsed outside of the cifs vfs such as nosuid.
487 Connect to server when port number override not specified, and tcp port
488 unitialized. Reset search to restart at correct file when kernel routine
489 filldir returns error during large directory searches (readdir).
493 Fix caching problem when files opened by multiple clients in which
494 page cache could contain stale data, and write through did
495 not occur often enough while file was still open when read ahead
496 (read oplock) not allowed. Treat "sep=" when first mount option
497 as an override of comma as the default separator between mount
502 Allow passwords longer than 16 bytes. Allow null password string.
506 Gracefully clean up failed mounts when attempting to mount to servers such as
507 Windows 98 that terminate tcp sessions during protocol negotiation. Handle
508 embedded commas in mount parsing of passwords.
512 Invalidate local inode cached pages on oplock break and when last file
513 instance is closed so that the client does not continue using stale local
514 copy rather than later modified server copy of file. Do not reconnect
515 when server drops the tcp session prematurely before negotiate
516 protocol response. Fix oops in reopen_file when dentry freed. Allow
517 the support for CIFS Unix Extensions to be disabled via proc interface.
521 Fix hang in commit_write during reconnection of open files under heavy load.
522 Fix unload_nls oops in a mount failure path. Serialize writes to same socket
523 which also fixes any possible races when cifs signatures are enabled in SMBs
524 being sent out of signature sequence number order.
528 Fix byte range locking bug (endian problem) causing bad offset and
533 Fix oops (in send_sig) caused by CIFS unmount code trying to
534 wake up the demultiplex thread after it had exited. Do not log
535 error on harmless oplock release of closed handle.
539 Fix unsafe global variable usage and password hash failure on gcc 3.3.1
540 Fix problem reconnecting secondary mounts to same server after session
541 failure. Fix invalid dentry - race in mkdir when directory gets created
542 by another client between the lookup and mkdir.
546 Fix to list processing in reopen_files. Fix reconnection when server hung
547 but tcpip session still alive. Set proper timeout on socket read.
551 Add missing mount options including iocharset. SMP fixes in write and open.
552 Fix errors in reconnecting after TCP session failure. Fix module unloading
553 of default nls codepage
557 Active smb transactions should never go negative (fix double FreeXid). Fix
558 list processing in file routines. Check return code on kmalloc in open.
559 Fix spinlock usage for SMP.
563 Fix oops in reopen_files when invalid dentry. drop dentry on server rename
564 and on revalidate errors. Fix cases where pid is now tgid. Fix return code
565 on create hard link when server does not support them.
569 Fix scheduling while atomic error in getting inode info on newly created file.
570 Fix truncate of existing files opened with O_CREAT but not O_TRUNC set.
574 Fix oops on write to dead tcp session. Remove error log write for case when file open
575 O_CREAT but not O_EXCL
579 Fix non-POSIX behavior on rename of open file and delete of open file by taking
580 advantage of trans2 SetFileInfo rename facility if available on target server.
581 Retry on ENOSPC and EAGAIN socket errors.
585 Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix
586 allocation size miscalculation. After oplock token lost do not read through
591 Fix oops on empty file readahead. Fix for file size handling for locally cached files.
595 Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files
596 during auto reconnection to server after server recovered from failure.
600 Finish support for Linux 2.5 open/create changes, which removes the
601 redundant NTCreate/QPathInfo/close that was sent during file create.
602 Enable oplock by default. Enable packet signing by default (needed to
603 access many recent Windows servers)
607 Fix oops when mounting to long server names caused by inverted parms to kmalloc.
608 Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
609 we will choose a cifs user session (smb uid) that better matches the local
610 uid if a) the mount uid does not match the current uid and b) we have another
611 session to the same server (ip address) for a different mount which
612 matches the current local uid.
616 Add support for mknod of block or character devices. Fix oplock
617 code (distributed caching) to properly send response to oplock
622 Finish up CIFS packet digital signing for the default
623 NTLM security case. This should help Windows 2003
624 network interoperability since it is common for
625 packet signing to be required now. Fix statfs (stat -f)
626 which recently started returning errors due to
627 invalid value (-1 instead of 0) being set in the
628 struct kstatfs f_ffiles field.
632 Fix oops on stopping oplock thread when removing cifs when
637 Fix mount options for ro (readonly), uid, gid and file and directory mode.
641 Fix errors displayed on failed mounts to be more understandable.
642 Fixed various incorrect or misleading smb to posix error code mappings.
646 Fix display of NTFS DFS junctions to display as symlinks.
647 They are the network equivalent. Fix oops in
648 cifs_partialpagewrite caused by missing spinlock protection
649 of openfile linked list. Allow writebehind caching errors to
650 be returned to the application at file close.
654 Clean up options displayed in /proc/mounts by show_options to
655 be more consistent with other filesystems.
659 Fix delete of readonly file to Windows servers. Reflect
660 presence or absence of read only dos attribute in mode
661 bits for servers that do not support CIFS Unix extensions.
662 Fix shortened results on readdir of large directories to
663 servers supporting CIFS Unix extensions (caused by
664 incorrect resume key).
668 Fix truncate bug (set file size) that could cause hangs e.g. running fsx
672 unload nls if mount fails.
676 Add resume key support to search (readdir) code to workaround
677 Windows bug. Add /proc/fs/cifs/LookupCacheEnable which
678 allows disabling caching of attribute information for
683 Add more oplock handling (distributed caching code). Remove
684 dead code. Remove excessive stack space utilization from
689 Fix oops in get dfs referral (triggered when null path sent in to
690 mount). Add support for overriding rsize at mount time.
694 Fix buffer overrun in readdir which caused intermittent kernel oopses.
695 Fix writepage code to release kmap on write data. Allow "-ip=" new
696 mount option to be passed in on parameter distinct from the first part
697 (server name portion of) the UNC name. Allow override of the
698 tcp port of the target server via new mount option "-port="
702 Fix search handle leak on rewind. Fix setuid and gid so that they are
703 reflected in the local inode immediately. Cleanup of whitespace
704 to make 2.4 and 2.5 versions more consistent.
709 Fix signal sending so that captive thread (cifsd) exits on umount
710 (which was causing the warning in kmem_cache_free of the request buffers
711 at rmmod time). This had broken as a sideeffect of the recent global
712 kernel change to daemonize. Fix memory leak in readdir code which
713 showed up in "ls -R" (and applications that did search rewinding).
717 Reconnect tids and fids after session reconnection (still do not
718 reconnect byte range locks though). Fix problem caching
719 lookup information for directory inodes, improving performance,
720 especially in deep directory trees. Fix various build warnings.
724 Finish fixes to commit write for caching/readahead consistency. fsx
725 now works to Samba servers. Fix oops caused when readahead
726 was interrupted by a signal.
730 Fix data corruption (in partial page after truncate) that caused fsx to
731 fail to Windows servers. Cleaned up some extraneous error logging in
732 common error paths. Add generic sendfile support.
736 Fix memory leak in AllocMidQEntry.
737 Finish reconnection logic, so connection with server can be dropped
738 (or server rebooted) and the cifs client will reconnect.
742 Fix temporary socket leak when bad userid or password specified
743 (or other SMBSessSetup failure). Increase maximum buffer size to slightly
744 over 16K to allow negotiation of up to Samba and Windows server default read
745 sizes. Add support for readpages
749 Fix oops when username not passed in on mount. Extensive fixes and improvements
750 to error logging (strip redundant newlines, change debug macros to ensure newline
751 passed in and to be more consistent). Fix writepage wrong file handle problem,
752 a readonly file handle could be incorrectly used to attempt to write out
753 file updates through the page cache to multiply open files. This could cause
754 the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
755 shares to the same Windows server when using different usernames
756 (doing this to Samba servers worked but Windows was rejecting it) - now it is
757 possible to use different userids when connecting to the same server from a
758 Linux client. Fix oops when treeDisconnect called during unmount on
759 previously freed socket.
763 Fix oops in readpages caused by not setting address space operations in inode in
768 Includes support for deleting of open files and renaming over existing files (per POSIX
769 requirement). Add readlink support for Windows junction points (directory symlinks).
773 Changed read and write to go through pagecache. Added additional address space operations.
774 Memory mapped operations now working.
778 Added writepage code for additional memory mapping support. Fixed leak in xids causing
779 the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
780 every stat call. Additional formatting cleanup.
784 Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
788 Fixes from Zwane Mwaikambo for adding missing return code checking in a few places.
789 Also included a modified version of his fix to protect global list manipulation of
790 the smb session and tree connection and mid related global variables.
794 Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
795 changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
796 buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
800 More stylistic updates to better match kernel style. Add additional statistics
801 for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
802 and CIFS Packet Signing enablement.
806 Replace call to sleep_on with safer wait_on_event.
807 Make stylistic changes to better match kernel style recommendations.
808 Remove most typedef usage (except for the PDUs themselves).
812 Update mount so the -unc mount option is no longer required (the ip address can be specified
813 in a UNC style device name. Implementation of readpage/writepage started.
817 Fix intermittent problem with incorrect smb header checking on badly
818 fragmented tcp responses
822 Fixes to setting of allocation size and file size.
826 Various 2.5.38 fixes. Now works on 2.5.38
830 Prepare for 2.5 kernel merge. Remove ifdefs.
834 Socket buffer management fixes. Fix dual free.
838 Various big endian fixes for hardlinks and symlinks and also for dfs.
842 Various big endian fixes for servers with Unix extensions such as Samba
846 Various FindNext fixes for incorrect filenames on large directory searches on big endian
847 clients. basic posix file i/o tests now work on big endian machines, not just le
851 SessionSetup and NegotiateProtocol now work from Big Endian machines.
852 Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older
853 versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7).
857 Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
858 files now return the correct number of links on fstat as they are repeatedly linked and unlinked.
862 Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
863 session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
864 Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
865 (which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).
869 Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
870 it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
874 Rewrote much of connection and mount/unmount logic to handle bugs with
875 multiple uses to same share, multiple users to same server etc.
879 Fixed major problem with dentry corruption (missing call to dput)
883 Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
884 Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
885 although corresponding function not fully implemented in the vfs yet
889 Fixed dentry caching bug, misc. cleanup
893 Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
894 on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
895 Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
899 Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
900 and tested against Samba 2.2.5
905 1) Fixed lockrange to be correct (it was one byte too short)
907 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
908 show range as locked when there is a conflict with an existing lock.
910 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
911 in most cases. Eventually will offer optional ability to query server for the correct perms.
913 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
914 but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
917 4) Fixed error logging of valid mount options
919 5) Removed logging of password field.
921 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
922 and cleaned them up and made them more consistent with other cifs functions.
924 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
925 (with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
926 nor is the symlink support using the Unix extensions
928 8) Started adding the readlink and follow_link code
