6 Fix oops on second mount to server when null auth is used.
7 Enable experimental Kerberos support. Return writebehind errors on flush
8 and sync so that events like out of disk space get reported properly on
9 cached files. Fix setxattr failure to certain Samba versions. Fix mount
10 of second share to disconnected server session (autoreconnect on this).
11 Add ability to modify cifs acls for handling chmod (when mounted with
12 cifsacl flag). Fix prefixpath path separator so we can handle mounts
13 with prefixpaths longer than one directory (one path component) when
14 mounted to Windows servers. Fix slow file open when cifsacl
19 Fix memory leak in statfs when mounted to very old servers (e.g.
20 Windows 9x). Add new feature "POSIX open" which allows servers
21 which support the current POSIX Extensions to provide better semantics
22 (e.g. delete for open files opened with posix open). Take into
23 account umask on posix mkdir not just older style mkdir. Add
24 ability to mount to IPC$ share (which allows CIFS named pipes to be
25 opened, read and written as if they were files). When 1st tree
26 connect fails (e.g. due to signing negotiation failure) fix
27 leak that causes cifsd not to stop and rmmod to fail to cleanup
28 cifs_request_buffers pool. Fix problem with POSIX Open/Mkdir on
29 bigendian architectures. Fix possible memory corruption when
30 EAGAIN returned on kern_recvmsg. Return better error if server
31 requires packet signing but client has disabled it. When mounted
32 with cifsacl mount option - mode bits are approximated based
33 on the contents of the ACL of the file or directory. When cifs
34 mount helper is missing convert make sure that UNC name
35 has backslash (not forward slash) between ip address of server
40 Fix NTLMv2 signing. NFS server mounted over cifs works (if cifs mount is
41 done with "serverino" mount option). Add support for POSIX Unlink
42 (helps with certain sharing violation cases when server such as
43 Samba supports newer POSIX CIFS Protocol Extensions). Add "nounix"
44 mount option to allow disabling the CIFS Unix Extensions for just
45 that mount. Fix hang on spinlock in find_writable_file (race when
46 reopening file after session crash). Byte range unlock request to
47 windows server could unlock more bytes (on server copy of file)
48 than intended if start of unlock request is well before start of
49 a previous byte range lock that we issued.
53 IPv6 support. Enable ipv6 addresses to be passed on mount (put the ipv6
54 address after the "ip=" mount option, at least until mount.cifs is fixed to
55 handle DNS host to ipv6 name translation). Accept override of uid or gid
56 on mount even when Unix Extensions are negotiated (it used to be ignored
57 when Unix Extensions were ignored). This allows users to override the
58 default uid and gid for files when they are certain that the uids or
59 gids on the server do not match those of the client. Make "sec=none"
60 mount override username (so that null user connection is attempted)
61 to match what documentation said. Support for very large reads, over 127K,
62 available to some newer servers (such as Samba 3.0.26 and later but
63 note that it also requires setting CIFSMaxBufSize at module install
64 time to a larger value which may hurt performance in some cases).
65 Make sign option force signing (or fail if server does not support it).
69 Fix mtime bouncing around from local idea of last write times to remote time.
70 Fix hang (in i_size_read) when simultaneous size update of same remote file
71 on smp system corrupts sequence number. Do not reread unnecessarily partial page
72 (which we are about to overwrite anyway) when writing out file opened rw.
73 When DOS attribute of file on non-Unix server's file changes on the server side
74 from read-only back to read-write, reflect this change in default file mode
75 (we had been leaving a file's mode read-only until the inode were reloaded).
76 Allow setting of attribute back to ATTR_NORMAL (removing readonly dos attribute
77 when archive dos attribute not set and we are changing mode back to writeable
78 on server which does not support the Unix Extensions). Remove read only dos
79 attribute on chmod when adding any write permission (ie on any of
80 user/group/other (not all of user/group/other ie 0222) when
81 mounted to windows. Add support for POSIX MkDir (slight performance
82 enhancement and eliminates the network race between the mkdir and set
83 path info of the mode).
88 Fix oops in list_del during mount caused by unaligned string.
89 Fix file corruption which could occur on some large file
90 copies caused by writepages page i/o completion bug.
91 Seek to SEEK_END forces check for update of file size for non-cached
92 files. Allow file size to be updated on remote extend of locally open,
93 non-cached file. Fix reconnect to newer Samba servers (or other servers
94 which support the CIFS Unix/POSIX extensions) so that we again tell the
95 server the Unix/POSIX cifs capabilities which we support (SetFSInfo).
96 Add experimental support for new POSIX Open/Mkdir (which returns
97 stat information on the open, and allows setting the mode).
101 Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
102 Allow null user to be specified on mount ("username="). Do not return
103 EINVAL on readdir when filldir fails due to overwritten blocksize
104 (fixes FC problem). Return error in rename 2nd attempt retry (ie report
105 if rename by handle also fails, after rename by path fails, we were
106 not reporting whether the retry worked or not). Fix NTLMv2 to
107 work to Windows servers (mount with option "sec=ntlmv2").
111 Do not time out lockw calls when using posix extensions. Do not
112 time out requests if server still responding reasonably fast
113 on requests on other threads. Improve POSIX locking emulation,
114 (lock cancel now works, and unlock of merged range works even
115 to Windows servers now). Fix oops on mount to lanman servers
116 (win9x, os/2 etc.) when null password. Do not send listxattr
117 (SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
118 problem (instantiate inodes/dentries in right order for readdir).
122 Rewritten sessionsetup support, including support for legacy SMB
123 session setup needed for OS/2 and older servers such as Windows 95 and 98.
124 Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
125 so we can do search (ls etc.) to OS/2. Do not send NTCreateX
126 or recent levels of FindFirst unless server says it supports NT SMBs
127 (instead use legacy equivalents from LANMAN dialect). Fix to allow
128 NTLMv2 authentication support (now can use stronger password hashing
129 on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
130 Allow override of global cifs security flags on mount via "sec=" option(s).
134 POSIX locking to servers which support CIFS POSIX Extensions
135 (disabled by default controlled by proc/fs/cifs/Experimental).
136 Handle conversion of long share names (especially Asian languages)
137 to Unicode during mount. Fix memory leak in sess struct on reconnect.
138 Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
139 cifs open which helps rare case when setpathinfo fails or server does
144 Fix slow oplock break when mounted to different servers at the same time and
145 the tids match and we try to find matching fid on wrong server. Fix read
146 looping when signing required by server (2.6.16 kernel only). Fix readdir
147 vs. rename race which could cause each to hang. Return . and .. even
148 if server does not. Allow searches to skip first three entries and
149 begin at any location. Fix oops in find_writeable_file.
153 Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
154 configure stronger authentication. Fix sfu symlinks so they can
155 be followed (not just recognized). Fix wraparound of bcc on
156 read responses when buffer size over 64K and also fix wrap of
157 max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
158 cifs_user_read and cifs_readpages (when EAGAIN on send of smb
159 on socket is returned over and over). Add POSIX (advisory) byte range
160 locking support (requires server with newest CIFS UNIX Extensions
161 to the protocol implemented). Slow down negprot slightly in port 139
162 RFC1001 case to give session_init time on buggy servers.
166 Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
167 of readpages by eliminating one extra memcpy. Allow update of file size
168 from remote server even if file is open for write as long as mount is
169 directio. Recognize share mode security and send NTLM encrypted password
170 on tree connect if share mode negotiated.
174 Defer close of a file handle slightly if pending writes depend on that handle
175 (this reduces the EBADF bad file handle errors that can be logged under heavy
176 stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
177 Fix SFU style symlinks and mknod needed for servers which do not support the
178 CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
179 dentries so files that the client sees as deleted but that later get created
180 on the server will be recognized. Add client side permission check on setattr.
181 Timeout stuck requests better (where server has never responded or sent corrupt
186 Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
187 to be smaller at first (but increasing) so large write performance performance
188 over GigE is better. Do not hang thread on illegal byte range lock response
189 from Windows (Windows can send an RFC1001 size which does not match smb size) by
190 allowing an SMBs TCP length to be up to a few bytes longer than it should be.
191 wsize and rsize can now be larger than negotiated buffer size if server
192 supports large readx/writex, even when directio mount flag not specified.
193 Write size will in many cases now be 16K instead of 4K which greatly helps
194 file copy performance on lightly loaded networks. Fix oops in dnotify
195 when experimental config flag enabled. Make cifsFYI more granular.
199 Fix readdir caching when unlink removes file in current search buffer,
200 and this is followed by a rewind search to just before the deleted entry.
201 Do not attempt to set ctime unless atime and/or mtime change requested
202 (most servers throw it away anyway). Fix length check of received smbs
203 to be more accurate. Fix big endian problem with mapchars mount option,
204 and with a field returned by statfs.
208 Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
209 For these older servers, add option for passing netbios name of server in
210 on mount (servernetbiosname). Add suspend support for power management, to
211 avoid cifsd thread preventing software suspend from working.
212 Add mount option for disabling the default behavior of sending byte range lock
213 requests to the server (necessary for certain applications which break with
214 mandatory lock behavior such as Evolution), and also mount option for
215 requesting case insensitive matching for path based requests (requesting
216 case sensitive is the default).
220 Add writepage performance improvements. Fix path name conversions
221 for long filenames on mounts which were done with "mapchars" mount option
222 specified. Ensure multiplex ids do not collide. Fix case in which
223 rmmod can oops if done soon after last unmount. Fix truncated
224 search (readdir) output when resume filename was a long filename.
225 Fix filename conversion when mapchars mount option was specified and
226 filename was a long filename.
230 Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
231 Do not oops if root user kills cifs oplock kernel thread or
232 kills the cifsd thread (NB: killing the cifs kernel threads is not
233 recommended, unmount and rmmod cifs will kill them when they are
234 no longer needed). Fix readdir to ASCII servers (ie older servers
235 which do not support Unicode) and also require asterisk.
236 Fix out of memory case in which data could be written one page
237 off in the page cache.
241 Fix caching problem, in which readdir of directory containing a file
242 which was cached could cause the file's time stamp to be updated
243 without invalidating the readahead data (so we could get stale
244 file data on the client for that file even as the server copy changed).
245 Cleanup response processing so cifsd can not loop when abnormally
251 Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
252 transact response for an SMB request and search entry split across two frames.
253 Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
254 as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
255 unless server explicitly claims to support them in CIFS Unix extensions
256 POSIX ACL capability bit. Fix packet signing when multiuser mounting with
257 different users from the same client to the same server. Fix oops in
258 cifs_close. Add mount option for remapping reserved characters in
259 filenames (also allow recognizing files with created by SFU which have any
260 of these seven reserved characters, except backslash, to be recognized).
261 Fix invalid transact2 message (we were sometimes trying to interpret
262 oplock breaks as SMB responses). Add ioctl for checking that the
263 current uid matches the uid of the mounter (needed by umount.cifs).
264 Reduce the number of large buffer allocations in cifs response processing
265 (significantly reduces memory pressure under heavy stress with multiple
266 processes accessing the same server at the same time).
270 Fix updates of DOS attributes and time fields so that files on NT4 servers
271 do not get marked delete on close. Display sizes of cifs buffer pools in
272 cifs stats. Fix oops in unmount when cifsd thread being killed by
273 shutdown. Add generic readv/writev and aio support. Report inode numbers
274 consistently in readdir and lookup (when serverino mount option is
275 specified use the inode number that the server reports - for both lookup
276 and readdir, otherwise by default the locally generated inode number is used
277 for inodes created in either path since servers are not always able to
278 provide unique inode numbers when exporting multiple volumes from under one
283 Allow new nouser_xattr mount parm to disable xattr support for user namespace.
284 Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
285 (mostly affects NT4 servers) by retry with handle based network operation.
286 Add new POSIX Query FS Info for returning statfs info more accurately.
287 Handle passwords with multiple commas in them.
291 Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
292 Fix capabilities flags for large readx so as to allow reads larger than 64K.
296 Add module init parm for large SMB buffer size (to allow it to be changed
297 from its default of 16K) which is especially useful for large file copy
298 when mounting with the directio mount option. Fix oops after
299 returning from mount when experimental ExtendedSecurity enabled and
300 SpnegoNegotiated returning invalid error. Fix case to retry better when
301 peek returns from 1 to 3 bytes on socket which should have more data.
302 Fixed path based calls (such as cifs lookup) to handle path names
303 longer than 530 (now can handle PATH_MAX). Fix pass through authentication
304 from Samba server to DC (Samba required dummy LM password).
308 Turn off DNOTIFY (directory change notification support) by default
309 (unless built with the experimental flag) to fix hang with KDE
310 file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
311 waiting on an SMB response) in SendReceive when session dies but
312 reconnects quickly from another task. Add module init parms for
313 minimum number of large and small network buffers in the buffer pools,
314 and for the maximum number of simultaneous requests.
318 Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
319 and other POSIX CIFS compliant servers. Fix error mapping for getfacl
320 to EOPNOTSUPP when server does not support posix acls on the wire. Fix
321 improperly zeroed buffer in CIFS Unix extensions set times call.
325 Fix internationalization problem in cifs readdir with filenames that map to
326 longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
327 for readdir to netapp servers. Fix search rewind (seek into readdir to return
328 non-consecutive entries). Do not do readdir when server negotiates
329 buffer size to small to fit filename. Add support for reading POSIX ACLs from
330 the server (add also acl and noacl mount options).
334 Optionally allow using server side inode numbers, rather than client generated
335 ones by specifying mount option "serverino" - this is required for some apps
336 to work which double check hardlinked files and have persistent inode numbers.
340 Multiple bigendian fixes. On little endian systems (for reconnect after
341 network failure) fix tcp session reconnect code so we do not try first
342 to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
343 as directories rather than symlinks because we can do follow link on them.
347 Add config option to enable XATTR (extended attribute) support, mapping
348 xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
349 minor fixes pointed out by the Stanford SWAT checker (mostly missing
350 or out of order NULL pointer checks in little used error paths).
354 Add new mount parm to control whether mode check (generic_permission) is done
355 on the client. If Unix extensions are enabled and the uids on the client
356 and server do not match, client permission checks are meaningless on
357 server uids that do not exist on the client (this does not affect the
358 normal ACL check which occurs on the server). Fix default uid
359 on mknod to match create and mkdir. Add optional mount parm to allow
360 override of the default uid behavior (in which the server sets the uid
361 and gid of newly created files). Normally for network filesystem mounts
362 user want the server to set the uid/gid on newly created files (rather than
363 using uid of the client processes you would in a local filesystem).
367 Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
368 info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
369 (in build_wildcard_path_from_dentry). Fix mknod to pass type field
370 (block/char/fifo) properly. Remove spurious mount warning log entry when
371 credentials passed as mount argument. Set major/minor device number in
372 inode for block and char devices when unix extensions enabled.
376 Fix /proc/fs/cifs/Stats and DebugData display to handle larger
377 amounts of return data. Properly limit requests to MAX_REQ (50
378 is the usual maximum active multiplex SMB/CIFS requests per server).
379 Do not kill cifsd (and thus hurt the other SMB session) when more than one
380 session to the same server (but with different userids) exists and one
381 of the two user's smb sessions is being removed while leaving the other.
382 Do not loop reconnecting in cifsd demultiplex thread when admin
383 kills the thread without going through unmount.
387 Do not rename hardlinked files (since that should be a noop). Flush
388 cached write behind data when reopening a file after session abend,
389 except when already in write. Grab per socket sem during reconnect
390 to avoid oops in sendmsg if overlapping with reconnect. Do not
391 reset cached inode file size on readdir for files open for write on
397 Update number of blocks in file so du command is happier (in Linux a fake
398 blocksize of 512 is required for calculating number of blocks in inode).
399 Fix prepare write of partial pages to read in data from server if possible.
400 Fix race on tcpStatus field between unmount and reconnection code, causing
401 cifsd process sometimes to hang around forever. Improve out of memory
402 checks in cifs_filldir
406 Fix incorrect file size in file handle based setattr on big endian hardware.
407 Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
408 and closing file structs in writepage/partialpagewrite. Add statistics
409 for each mounted share (new menuconfig option). Fix endianness problem in
410 volume information displayed in /proc/fs/cifs/DebugData (only affects
411 affects big endian architectures). Prevent renames while constructing
412 path names for open, mkdir and rmdir.
416 Change to mempools for alloc smb request buffers and multiplex structs
417 to better handle low memory problems (and potential deadlocks).
421 Fix incomplete listings of large directories on Samba servers when Unix
422 extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
423 rename deadlock when writing out dirty pages at same time.
427 Fix open of files in which O_CREATE can cause the mode to change in
428 some cases. Fix case in which retry of write overlaps file close.
429 Fix PPC64 build error. Reduce excessive stack usage in smb password
430 hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
434 Fixes for large file copy, signal handling, socket retry, buffer
435 allocation and low memory situations.
439 Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
440 also now allowing support for specifying client netbiosname. NT4 support added.
444 Fix reconnection (and certain failed mounts) to properly wake up the
445 blocked users thread so it does not seem hung (in some cases was blocked
446 until the cifs receive timeout expired). Fix spurious error logging
447 to kernel log when application with open network files killed.
451 Fix /proc/fs module unload warning message (that could be logged
452 to the kernel log). Fix intermittent failure in connectathon
453 test7 (hardlink count not immediately refreshed in case in which
454 inode metadata can be incorrectly kept cached when time near zero)
458 Allow file_mode and dir_mode (specified at mount time) to be enforced
459 locally (the server already enforced its own ACLs too) for servers
460 that do not report the correct mode (do not support the
461 CIFS Unix Extensions).
465 Fix some small memory leaks in some unmount error paths. Fix major leak
466 of cache pages in readpages causing multiple read oriented stress
467 testcases (including fsx, and even large file copy) to fail over time.
471 Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
472 This allows files that differ only in case and improves performance of file
473 creation and file open to such servers. Fix semaphore conflict which causes
474 slow delete of open file to Samba (which unfortunately can cause an oplock
475 break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
479 fixes to cifs_readpages for fsx test case
483 Fix caching data integrity bug when extending file size especially when no
484 oplock on file. Fix spurious logging of valid already parsed mount options
485 that are parsed outside of the cifs vfs such as nosuid.
490 Connect to server when port number override not specified, and tcp port
491 unitialized. Reset search to restart at correct file when kernel routine
492 filldir returns error during large directory searches (readdir).
496 Fix caching problem when files opened by multiple clients in which
497 page cache could contain stale data, and write through did
498 not occur often enough while file was still open when read ahead
499 (read oplock) not allowed. Treat "sep=" when first mount option
500 as an override of comma as the default separator between mount
505 Allow passwords longer than 16 bytes. Allow null password string.
509 Gracefully clean up failed mounts when attempting to mount to servers such as
510 Windows 98 that terminate tcp sessions during protocol negotiation. Handle
511 embedded commas in mount parsing of passwords.
515 Invalidate local inode cached pages on oplock break and when last file
516 instance is closed so that the client does not continue using stale local
517 copy rather than later modified server copy of file. Do not reconnect
518 when server drops the tcp session prematurely before negotiate
519 protocol response. Fix oops in reopen_file when dentry freed. Allow
520 the support for CIFS Unix Extensions to be disabled via proc interface.
524 Fix hang in commit_write during reconnection of open files under heavy load.
525 Fix unload_nls oops in a mount failure path. Serialize writes to same socket
526 which also fixes any possible races when cifs signatures are enabled in SMBs
527 being sent out of signature sequence number order.
531 Fix byte range locking bug (endian problem) causing bad offset and
536 Fix oops (in send_sig) caused by CIFS unmount code trying to
537 wake up the demultiplex thread after it had exited. Do not log
538 error on harmless oplock release of closed handle.
542 Fix unsafe global variable usage and password hash failure on gcc 3.3.1
543 Fix problem reconnecting secondary mounts to same server after session
544 failure. Fix invalid dentry - race in mkdir when directory gets created
545 by another client between the lookup and mkdir.
549 Fix to list processing in reopen_files. Fix reconnection when server hung
550 but tcpip session still alive. Set proper timeout on socket read.
554 Add missing mount options including iocharset. SMP fixes in write and open.
555 Fix errors in reconnecting after TCP session failure. Fix module unloading
556 of default nls codepage
560 Active smb transactions should never go negative (fix double FreeXid). Fix
561 list processing in file routines. Check return code on kmalloc in open.
562 Fix spinlock usage for SMP.
566 Fix oops in reopen_files when invalid dentry. drop dentry on server rename
567 and on revalidate errors. Fix cases where pid is now tgid. Fix return code
568 on create hard link when server does not support them.
572 Fix scheduling while atomic error in getting inode info on newly created file.
573 Fix truncate of existing files opened with O_CREAT but not O_TRUNC set.
577 Fix oops on write to dead tcp session. Remove error log write for case when file open
578 O_CREAT but not O_EXCL
582 Fix non-POSIX behavior on rename of open file and delete of open file by taking
583 advantage of trans2 SetFileInfo rename facility if available on target server.
584 Retry on ENOSPC and EAGAIN socket errors.
588 Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix
589 allocation size miscalculation. After oplock token lost do not read through
594 Fix oops on empty file readahead. Fix for file size handling for locally cached files.
598 Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files
599 during auto reconnection to server after server recovered from failure.
603 Finish support for Linux 2.5 open/create changes, which removes the
604 redundant NTCreate/QPathInfo/close that was sent during file create.
605 Enable oplock by default. Enable packet signing by default (needed to
606 access many recent Windows servers)
610 Fix oops when mounting to long server names caused by inverted parms to kmalloc.
611 Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
612 we will choose a cifs user session (smb uid) that better matches the local
613 uid if a) the mount uid does not match the current uid and b) we have another
614 session to the same server (ip address) for a different mount which
615 matches the current local uid.
619 Add support for mknod of block or character devices. Fix oplock
620 code (distributed caching) to properly send response to oplock
625 Finish up CIFS packet digital signing for the default
626 NTLM security case. This should help Windows 2003
627 network interoperability since it is common for
628 packet signing to be required now. Fix statfs (stat -f)
629 which recently started returning errors due to
630 invalid value (-1 instead of 0) being set in the
631 struct kstatfs f_ffiles field.
635 Fix oops on stopping oplock thread when removing cifs when
640 Fix mount options for ro (readonly), uid, gid and file and directory mode.
644 Fix errors displayed on failed mounts to be more understandable.
645 Fixed various incorrect or misleading smb to posix error code mappings.
649 Fix display of NTFS DFS junctions to display as symlinks.
650 They are the network equivalent. Fix oops in
651 cifs_partialpagewrite caused by missing spinlock protection
652 of openfile linked list. Allow writebehind caching errors to
653 be returned to the application at file close.
657 Clean up options displayed in /proc/mounts by show_options to
658 be more consistent with other filesystems.
662 Fix delete of readonly file to Windows servers. Reflect
663 presence or absence of read only dos attribute in mode
664 bits for servers that do not support CIFS Unix extensions.
665 Fix shortened results on readdir of large directories to
666 servers supporting CIFS Unix extensions (caused by
667 incorrect resume key).
671 Fix truncate bug (set file size) that could cause hangs e.g. running fsx
675 unload nls if mount fails.
679 Add resume key support to search (readdir) code to workaround
680 Windows bug. Add /proc/fs/cifs/LookupCacheEnable which
681 allows disabling caching of attribute information for
686 Add more oplock handling (distributed caching code). Remove
687 dead code. Remove excessive stack space utilization from
692 Fix oops in get dfs referral (triggered when null path sent in to
693 mount). Add support for overriding rsize at mount time.
697 Fix buffer overrun in readdir which caused intermittent kernel oopses.
698 Fix writepage code to release kmap on write data. Allow "-ip=" new
699 mount option to be passed in on parameter distinct from the first part
700 (server name portion of) the UNC name. Allow override of the
701 tcp port of the target server via new mount option "-port="
705 Fix search handle leak on rewind. Fix setuid and gid so that they are
706 reflected in the local inode immediately. Cleanup of whitespace
707 to make 2.4 and 2.5 versions more consistent.
712 Fix signal sending so that captive thread (cifsd) exits on umount
713 (which was causing the warning in kmem_cache_free of the request buffers
714 at rmmod time). This had broken as a sideeffect of the recent global
715 kernel change to daemonize. Fix memory leak in readdir code which
716 showed up in "ls -R" (and applications that did search rewinding).
720 Reconnect tids and fids after session reconnection (still do not
721 reconnect byte range locks though). Fix problem caching
722 lookup information for directory inodes, improving performance,
723 especially in deep directory trees. Fix various build warnings.
727 Finish fixes to commit write for caching/readahead consistency. fsx
728 now works to Samba servers. Fix oops caused when readahead
729 was interrupted by a signal.
733 Fix data corruption (in partial page after truncate) that caused fsx to
734 fail to Windows servers. Cleaned up some extraneous error logging in
735 common error paths. Add generic sendfile support.
739 Fix memory leak in AllocMidQEntry.
740 Finish reconnection logic, so connection with server can be dropped
741 (or server rebooted) and the cifs client will reconnect.
745 Fix temporary socket leak when bad userid or password specified
746 (or other SMBSessSetup failure). Increase maximum buffer size to slightly
747 over 16K to allow negotiation of up to Samba and Windows server default read
748 sizes. Add support for readpages
752 Fix oops when username not passed in on mount. Extensive fixes and improvements
753 to error logging (strip redundant newlines, change debug macros to ensure newline
754 passed in and to be more consistent). Fix writepage wrong file handle problem,
755 a readonly file handle could be incorrectly used to attempt to write out
756 file updates through the page cache to multiply open files. This could cause
757 the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
758 shares to the same Windows server when using different usernames
759 (doing this to Samba servers worked but Windows was rejecting it) - now it is
760 possible to use different userids when connecting to the same server from a
761 Linux client. Fix oops when treeDisconnect called during unmount on
762 previously freed socket.
766 Fix oops in readpages caused by not setting address space operations in inode in
771 Includes support for deleting of open files and renaming over existing files (per POSIX
772 requirement). Add readlink support for Windows junction points (directory symlinks).
776 Changed read and write to go through pagecache. Added additional address space operations.
777 Memory mapped operations now working.
781 Added writepage code for additional memory mapping support. Fixed leak in xids causing
782 the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
783 every stat call. Additional formatting cleanup.
787 Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
791 Fixes from Zwane Mwaikambo for adding missing return code checking in a few places.
792 Also included a modified version of his fix to protect global list manipulation of
793 the smb session and tree connection and mid related global variables.
797 Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
798 changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
799 buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
803 More stylistic updates to better match kernel style. Add additional statistics
804 for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
805 and CIFS Packet Signing enablement.
809 Replace call to sleep_on with safer wait_on_event.
810 Make stylistic changes to better match kernel style recommendations.
811 Remove most typedef usage (except for the PDUs themselves).
815 Update mount so the -unc mount option is no longer required (the ip address can be specified
816 in a UNC style device name. Implementation of readpage/writepage started.
820 Fix intermittent problem with incorrect smb header checking on badly
821 fragmented tcp responses
825 Fixes to setting of allocation size and file size.
829 Various 2.5.38 fixes. Now works on 2.5.38
833 Prepare for 2.5 kernel merge. Remove ifdefs.
837 Socket buffer management fixes. Fix dual free.
841 Various big endian fixes for hardlinks and symlinks and also for dfs.
845 Various big endian fixes for servers with Unix extensions such as Samba
849 Various FindNext fixes for incorrect filenames on large directory searches on big endian
850 clients. basic posix file i/o tests now work on big endian machines, not just le
854 SessionSetup and NegotiateProtocol now work from Big Endian machines.
855 Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older
856 versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7).
860 Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
861 files now return the correct number of links on fstat as they are repeatedly linked and unlinked.
865 Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
866 session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
867 Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
868 (which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).
872 Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
873 it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
877 Rewrote much of connection and mount/unmount logic to handle bugs with
878 multiple uses to same share, multiple users to same server etc.
882 Fixed major problem with dentry corruption (missing call to dput)
886 Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
887 Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
888 although corresponding function not fully implemented in the vfs yet
892 Fixed dentry caching bug, misc. cleanup
896 Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
897 on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
898 Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
902 Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
903 and tested against Samba 2.2.5
908 1) Fixed lockrange to be correct (it was one byte too short)
910 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
911 show range as locked when there is a conflict with an existing lock.
913 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
914 in most cases. Eventually will offer optional ability to query server for the correct perms.
916 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
917 but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
920 4) Fixed error logging of valid mount options
922 5) Removed logging of password field.
924 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
925 and cleaned them up and made them more consistent with other cifs functions.
927 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
928 (with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
929 nor is the symlink support using the Unix extensions
931 8) Started adding the readlink and follow_link code
