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