3 Add "forcemandatorylock" mount option to allow user to use mandatory
4 rather than posix (advisory) byte range locks, even though server would
5 support posix byte range locks. Fix query of root inode when prefixpath
6 specified and user does not have access to query information about the
7 top of the share. Fix problem in 2.6.28 resolving DFS paths to
8 Samba servers (worked to Windows). Fix rmdir so that pending search
9 (readdir) requests do not get invalid results which include the now
14 Various fixes to make delete of open files behavior more predictable
15 (when delete of an open file fails we mark the file as "delete-on-close"
16 in a way that more servers accept, but only if we can first rename the
17 file to a temporary name). Add experimental support for more safely
18 handling fcntl(F_SETLEASE). Convert cifs to using blocking tcp
19 sends, and also let tcp autotune the socket send and receive buffers.
20 This reduces the number of EAGAIN errors returned by TCP/IP in
21 high stress workloads (and the number of retries on socket writes
22 when sending large SMBWriteX requests). Fix case in which a portion of
23 data can in some cases not get written to the file on the server before the
24 file is closed. Fix DFS parsing to properly handle path consumed field,
25 and to handle certain codepage conversions better. Fix mount and
26 umount race that can cause oops in mount or umount or reconnect.
30 Fix premature write failure on congested networks (we would give up
31 on EAGAIN from the socket too quickly on large writes).
32 Cifs_mkdir and cifs_create now respect the setgid bit on parent dir.
33 Fix endian problems in acl (mode from/to cifs acl) on bigendian
34 architectures. Fix problems with preserving timestamps on copying open
35 files (e.g. "cp -a") to Windows servers. For mkdir and create honor setgid bit
36 on parent directory when server supports Unix Extensions but not POSIX
37 create. Update cifs.upcall version to handle new Kerberos sec flags
38 (this requires update of cifs.upcall program from Samba). Fix memory leak
39 on dns_upcall (resolving DFS referralls). Fix plain text password
40 authentication (requires setting SecurityFlags to 0x30030 to enable
41 lanman and plain text though). Fix writes to be at correct offset when
42 file is open with O_APPEND and file is on a directio (forcediretio) mount.
43 Fix bug in rewinding readdir directory searches. Add nodfs mount option.
47 DFS support added (Microsoft Distributed File System client support needed
48 for referrals which enable a hierarchical name space among servers).
49 Disable temporary caching of mode bits to servers which do not support
50 storing of mode (e.g. Windows servers, when client mounts without cifsacl
51 mount option) and add new "dynperm" mount option to enable temporary caching
52 of mode (enable old behavior). Fix hang on mount caused when server crashes
53 tcp session during negotiate protocol.
57 Fix oops on second mount to server when null auth is used.
58 Enable experimental Kerberos support. Return writebehind errors on flush
59 and sync so that events like out of disk space get reported properly on
60 cached files. Fix setxattr failure to certain Samba versions. Fix mount
61 of second share to disconnected server session (autoreconnect on this).
62 Add ability to modify cifs acls for handling chmod (when mounted with
63 cifsacl flag). Fix prefixpath path separator so we can handle mounts
64 with prefixpaths longer than one directory (one path component) when
65 mounted to Windows servers. Fix slow file open when cifsacl
66 enabled. Fix memory leak in FindNext when the SMB call returns -EBADF.
71 Fix memory leak in statfs when mounted to very old servers (e.g.
72 Windows 9x). Add new feature "POSIX open" which allows servers
73 which support the current POSIX Extensions to provide better semantics
74 (e.g. delete for open files opened with posix open). Take into
75 account umask on posix mkdir not just older style mkdir. Add
76 ability to mount to IPC$ share (which allows CIFS named pipes to be
77 opened, read and written as if they were files). When 1st tree
78 connect fails (e.g. due to signing negotiation failure) fix
79 leak that causes cifsd not to stop and rmmod to fail to cleanup
80 cifs_request_buffers pool. Fix problem with POSIX Open/Mkdir on
81 bigendian architectures. Fix possible memory corruption when
82 EAGAIN returned on kern_recvmsg. Return better error if server
83 requires packet signing but client has disabled it. When mounted
84 with cifsacl mount option - mode bits are approximated based
85 on the contents of the ACL of the file or directory. When cifs
86 mount helper is missing convert make sure that UNC name
87 has backslash (not forward slash) between ip address of server
92 Fix NTLMv2 signing. NFS server mounted over cifs works (if cifs mount is
93 done with "serverino" mount option). Add support for POSIX Unlink
94 (helps with certain sharing violation cases when server such as
95 Samba supports newer POSIX CIFS Protocol Extensions). Add "nounix"
96 mount option to allow disabling the CIFS Unix Extensions for just
97 that mount. Fix hang on spinlock in find_writable_file (race when
98 reopening file after session crash). Byte range unlock request to
99 windows server could unlock more bytes (on server copy of file)
100 than intended if start of unlock request is well before start of
101 a previous byte range lock that we issued.
105 IPv6 support. Enable ipv6 addresses to be passed on mount (put the ipv6
106 address after the "ip=" mount option, at least until mount.cifs is fixed to
107 handle DNS host to ipv6 name translation). Accept override of uid or gid
108 on mount even when Unix Extensions are negotiated (it used to be ignored
109 when Unix Extensions were ignored). This allows users to override the
110 default uid and gid for files when they are certain that the uids or
111 gids on the server do not match those of the client. Make "sec=none"
112 mount override username (so that null user connection is attempted)
113 to match what documentation said. Support for very large reads, over 127K,
114 available to some newer servers (such as Samba 3.0.26 and later but
115 note that it also requires setting CIFSMaxBufSize at module install
116 time to a larger value which may hurt performance in some cases).
117 Make sign option force signing (or fail if server does not support it).
121 Fix mtime bouncing around from local idea of last write times to remote time.
122 Fix hang (in i_size_read) when simultaneous size update of same remote file
123 on smp system corrupts sequence number. Do not reread unnecessarily partial page
124 (which we are about to overwrite anyway) when writing out file opened rw.
125 When DOS attribute of file on non-Unix server's file changes on the server side
126 from read-only back to read-write, reflect this change in default file mode
127 (we had been leaving a file's mode read-only until the inode were reloaded).
128 Allow setting of attribute back to ATTR_NORMAL (removing readonly dos attribute
129 when archive dos attribute not set and we are changing mode back to writeable
130 on server which does not support the Unix Extensions). Remove read only dos
131 attribute on chmod when adding any write permission (ie on any of
132 user/group/other (not all of user/group/other ie 0222) when
133 mounted to windows. Add support for POSIX MkDir (slight performance
134 enhancement and eliminates the network race between the mkdir and set
135 path info of the mode).
140 Fix oops in list_del during mount caused by unaligned string.
141 Fix file corruption which could occur on some large file
142 copies caused by writepages page i/o completion bug.
143 Seek to SEEK_END forces check for update of file size for non-cached
144 files. Allow file size to be updated on remote extend of locally open,
145 non-cached file. Fix reconnect to newer Samba servers (or other servers
146 which support the CIFS Unix/POSIX extensions) so that we again tell the
147 server the Unix/POSIX cifs capabilities which we support (SetFSInfo).
148 Add experimental support for new POSIX Open/Mkdir (which returns
149 stat information on the open, and allows setting the mode).
153 Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
154 Allow null user to be specified on mount ("username="). Do not return
155 EINVAL on readdir when filldir fails due to overwritten blocksize
156 (fixes FC problem). Return error in rename 2nd attempt retry (ie report
157 if rename by handle also fails, after rename by path fails, we were
158 not reporting whether the retry worked or not). Fix NTLMv2 to
159 work to Windows servers (mount with option "sec=ntlmv2").
163 Do not time out lockw calls when using posix extensions. Do not
164 time out requests if server still responding reasonably fast
165 on requests on other threads. Improve POSIX locking emulation,
166 (lock cancel now works, and unlock of merged range works even
167 to Windows servers now). Fix oops on mount to lanman servers
168 (win9x, os/2 etc.) when null password. Do not send listxattr
169 (SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
170 problem (instantiate inodes/dentries in right order for readdir).
174 Rewritten sessionsetup support, including support for legacy SMB
175 session setup needed for OS/2 and older servers such as Windows 95 and 98.
176 Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
177 so we can do search (ls etc.) to OS/2. Do not send NTCreateX
178 or recent levels of FindFirst unless server says it supports NT SMBs
179 (instead use legacy equivalents from LANMAN dialect). Fix to allow
180 NTLMv2 authentication support (now can use stronger password hashing
181 on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
182 Allow override of global cifs security flags on mount via "sec=" option(s).
186 POSIX locking to servers which support CIFS POSIX Extensions
187 (disabled by default controlled by proc/fs/cifs/Experimental).
188 Handle conversion of long share names (especially Asian languages)
189 to Unicode during mount. Fix memory leak in sess struct on reconnect.
190 Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
191 cifs open which helps rare case when setpathinfo fails or server does
196 Fix slow oplock break when mounted to different servers at the same time and
197 the tids match and we try to find matching fid on wrong server. Fix read
198 looping when signing required by server (2.6.16 kernel only). Fix readdir
199 vs. rename race which could cause each to hang. Return . and .. even
200 if server does not. Allow searches to skip first three entries and
201 begin at any location. Fix oops in find_writeable_file.
205 Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
206 configure stronger authentication. Fix sfu symlinks so they can
207 be followed (not just recognized). Fix wraparound of bcc on
208 read responses when buffer size over 64K and also fix wrap of
209 max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
210 cifs_user_read and cifs_readpages (when EAGAIN on send of smb
211 on socket is returned over and over). Add POSIX (advisory) byte range
212 locking support (requires server with newest CIFS UNIX Extensions
213 to the protocol implemented). Slow down negprot slightly in port 139
214 RFC1001 case to give session_init time on buggy servers.
218 Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
219 of readpages by eliminating one extra memcpy. Allow update of file size
220 from remote server even if file is open for write as long as mount is
221 directio. Recognize share mode security and send NTLM encrypted password
222 on tree connect if share mode negotiated.
226 Defer close of a file handle slightly if pending writes depend on that handle
227 (this reduces the EBADF bad file handle errors that can be logged under heavy
228 stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
229 Fix SFU style symlinks and mknod needed for servers which do not support the
230 CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
231 dentries so files that the client sees as deleted but that later get created
232 on the server will be recognized. Add client side permission check on setattr.
233 Timeout stuck requests better (where server has never responded or sent corrupt
238 Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
239 to be smaller at first (but increasing) so large write performance performance
240 over GigE is better. Do not hang thread on illegal byte range lock response
241 from Windows (Windows can send an RFC1001 size which does not match smb size) by
242 allowing an SMBs TCP length to be up to a few bytes longer than it should be.
243 wsize and rsize can now be larger than negotiated buffer size if server
244 supports large readx/writex, even when directio mount flag not specified.
245 Write size will in many cases now be 16K instead of 4K which greatly helps
246 file copy performance on lightly loaded networks. Fix oops in dnotify
247 when experimental config flag enabled. Make cifsFYI more granular.
251 Fix readdir caching when unlink removes file in current search buffer,
252 and this is followed by a rewind search to just before the deleted entry.
253 Do not attempt to set ctime unless atime and/or mtime change requested
254 (most servers throw it away anyway). Fix length check of received smbs
255 to be more accurate. Fix big endian problem with mapchars mount option,
256 and with a field returned by statfs.
260 Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
261 For these older servers, add option for passing netbios name of server in
262 on mount (servernetbiosname). Add suspend support for power management, to
263 avoid cifsd thread preventing software suspend from working.
264 Add mount option for disabling the default behavior of sending byte range lock
265 requests to the server (necessary for certain applications which break with
266 mandatory lock behavior such as Evolution), and also mount option for
267 requesting case insensitive matching for path based requests (requesting
268 case sensitive is the default).
272 Add writepage performance improvements. Fix path name conversions
273 for long filenames on mounts which were done with "mapchars" mount option
274 specified. Ensure multiplex ids do not collide. Fix case in which
275 rmmod can oops if done soon after last unmount. Fix truncated
276 search (readdir) output when resume filename was a long filename.
277 Fix filename conversion when mapchars mount option was specified and
278 filename was a long filename.
282 Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
283 Do not oops if root user kills cifs oplock kernel thread or
284 kills the cifsd thread (NB: killing the cifs kernel threads is not
285 recommended, unmount and rmmod cifs will kill them when they are
286 no longer needed). Fix readdir to ASCII servers (ie older servers
287 which do not support Unicode) and also require asterisk.
288 Fix out of memory case in which data could be written one page
289 off in the page cache.
293 Fix caching problem, in which readdir of directory containing a file
294 which was cached could cause the file's time stamp to be updated
295 without invalidating the readahead data (so we could get stale
296 file data on the client for that file even as the server copy changed).
297 Cleanup response processing so cifsd can not loop when abnormally
303 Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
304 transact response for an SMB request and search entry split across two frames.
305 Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
306 as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
307 unless server explicitly claims to support them in CIFS Unix extensions
308 POSIX ACL capability bit. Fix packet signing when multiuser mounting with
309 different users from the same client to the same server. Fix oops in
310 cifs_close. Add mount option for remapping reserved characters in
311 filenames (also allow recognizing files with created by SFU which have any
312 of these seven reserved characters, except backslash, to be recognized).
313 Fix invalid transact2 message (we were sometimes trying to interpret
314 oplock breaks as SMB responses). Add ioctl for checking that the
315 current uid matches the uid of the mounter (needed by umount.cifs).
316 Reduce the number of large buffer allocations in cifs response processing
317 (significantly reduces memory pressure under heavy stress with multiple
318 processes accessing the same server at the same time).
322 Fix updates of DOS attributes and time fields so that files on NT4 servers
323 do not get marked delete on close. Display sizes of cifs buffer pools in
324 cifs stats. Fix oops in unmount when cifsd thread being killed by
325 shutdown. Add generic readv/writev and aio support. Report inode numbers
326 consistently in readdir and lookup (when serverino mount option is
327 specified use the inode number that the server reports - for both lookup
328 and readdir, otherwise by default the locally generated inode number is used
329 for inodes created in either path since servers are not always able to
330 provide unique inode numbers when exporting multiple volumes from under one
335 Allow new nouser_xattr mount parm to disable xattr support for user namespace.
336 Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
337 (mostly affects NT4 servers) by retry with handle based network operation.
338 Add new POSIX Query FS Info for returning statfs info more accurately.
339 Handle passwords with multiple commas in them.
343 Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
344 Fix capabilities flags for large readx so as to allow reads larger than 64K.
348 Add module init parm for large SMB buffer size (to allow it to be changed
349 from its default of 16K) which is especially useful for large file copy
350 when mounting with the directio mount option. Fix oops after
351 returning from mount when experimental ExtendedSecurity enabled and
352 SpnegoNegotiated returning invalid error. Fix case to retry better when
353 peek returns from 1 to 3 bytes on socket which should have more data.
354 Fixed path based calls (such as cifs lookup) to handle path names
355 longer than 530 (now can handle PATH_MAX). Fix pass through authentication
356 from Samba server to DC (Samba required dummy LM password).
360 Turn off DNOTIFY (directory change notification support) by default
361 (unless built with the experimental flag) to fix hang with KDE
362 file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
363 waiting on an SMB response) in SendReceive when session dies but
364 reconnects quickly from another task. Add module init parms for
365 minimum number of large and small network buffers in the buffer pools,
366 and for the maximum number of simultaneous requests.
370 Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
371 and other POSIX CIFS compliant servers. Fix error mapping for getfacl
372 to EOPNOTSUPP when server does not support posix acls on the wire. Fix
373 improperly zeroed buffer in CIFS Unix extensions set times call.
377 Fix internationalization problem in cifs readdir with filenames that map to
378 longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
379 for readdir to netapp servers. Fix search rewind (seek into readdir to return
380 non-consecutive entries). Do not do readdir when server negotiates
381 buffer size to small to fit filename. Add support for reading POSIX ACLs from
382 the server (add also acl and noacl mount options).
386 Optionally allow using server side inode numbers, rather than client generated
387 ones by specifying mount option "serverino" - this is required for some apps
388 to work which double check hardlinked files and have persistent inode numbers.
392 Multiple bigendian fixes. On little endian systems (for reconnect after
393 network failure) fix tcp session reconnect code so we do not try first
394 to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
395 as directories rather than symlinks because we can do follow link on them.
399 Add config option to enable XATTR (extended attribute) support, mapping
400 xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
401 minor fixes pointed out by the Stanford SWAT checker (mostly missing
402 or out of order NULL pointer checks in little used error paths).
406 Add new mount parm to control whether mode check (generic_permission) is done
407 on the client. If Unix extensions are enabled and the uids on the client
408 and server do not match, client permission checks are meaningless on
409 server uids that do not exist on the client (this does not affect the
410 normal ACL check which occurs on the server). Fix default uid
411 on mknod to match create and mkdir. Add optional mount parm to allow
412 override of the default uid behavior (in which the server sets the uid
413 and gid of newly created files). Normally for network filesystem mounts
414 user want the server to set the uid/gid on newly created files (rather than
415 using uid of the client processes you would in a local filesystem).
419 Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
420 info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
421 (in build_wildcard_path_from_dentry). Fix mknod to pass type field
422 (block/char/fifo) properly. Remove spurious mount warning log entry when
423 credentials passed as mount argument. Set major/minor device number in
424 inode for block and char devices when unix extensions enabled.
428 Fix /proc/fs/cifs/Stats and DebugData display to handle larger
429 amounts of return data. Properly limit requests to MAX_REQ (50
430 is the usual maximum active multiplex SMB/CIFS requests per server).
431 Do not kill cifsd (and thus hurt the other SMB session) when more than one
432 session to the same server (but with different userids) exists and one
433 of the two user's smb sessions is being removed while leaving the other.
434 Do not loop reconnecting in cifsd demultiplex thread when admin
435 kills the thread without going through unmount.
439 Do not rename hardlinked files (since that should be a noop). Flush
440 cached write behind data when reopening a file after session abend,
441 except when already in write. Grab per socket sem during reconnect
442 to avoid oops in sendmsg if overlapping with reconnect. Do not
443 reset cached inode file size on readdir for files open for write on
449 Update number of blocks in file so du command is happier (in Linux a fake
450 blocksize of 512 is required for calculating number of blocks in inode).
451 Fix prepare write of partial pages to read in data from server if possible.
452 Fix race on tcpStatus field between unmount and reconnection code, causing
453 cifsd process sometimes to hang around forever. Improve out of memory
454 checks in cifs_filldir
458 Fix incorrect file size in file handle based setattr on big endian hardware.
459 Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
460 and closing file structs in writepage/partialpagewrite. Add statistics
461 for each mounted share (new menuconfig option). Fix endianness problem in
462 volume information displayed in /proc/fs/cifs/DebugData (only affects
463 affects big endian architectures). Prevent renames while constructing
464 path names for open, mkdir and rmdir.
468 Change to mempools for alloc smb request buffers and multiplex structs
469 to better handle low memory problems (and potential deadlocks).
473 Fix incomplete listings of large directories on Samba servers when Unix
474 extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
475 rename deadlock when writing out dirty pages at same time.
479 Fix open of files in which O_CREATE can cause the mode to change in
480 some cases. Fix case in which retry of write overlaps file close.
481 Fix PPC64 build error. Reduce excessive stack usage in smb password
482 hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
486 Fixes for large file copy, signal handling, socket retry, buffer
487 allocation and low memory situations.
491 Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
492 also now allowing support for specifying client netbiosname. NT4 support added.
496 Fix reconnection (and certain failed mounts) to properly wake up the
497 blocked users thread so it does not seem hung (in some cases was blocked
498 until the cifs receive timeout expired). Fix spurious error logging
499 to kernel log when application with open network files killed.
503 Fix /proc/fs module unload warning message (that could be logged
504 to the kernel log). Fix intermittent failure in connectathon
505 test7 (hardlink count not immediately refreshed in case in which
506 inode metadata can be incorrectly kept cached when time near zero)
510 Allow file_mode and dir_mode (specified at mount time) to be enforced
511 locally (the server already enforced its own ACLs too) for servers
512 that do not report the correct mode (do not support the
513 CIFS Unix Extensions).
517 Fix some small memory leaks in some unmount error paths. Fix major leak
518 of cache pages in readpages causing multiple read oriented stress
519 testcases (including fsx, and even large file copy) to fail over time.
523 Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
524 This allows files that differ only in case and improves performance of file
525 creation and file open to such servers. Fix semaphore conflict which causes
526 slow delete of open file to Samba (which unfortunately can cause an oplock
527 break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
531 fixes to cifs_readpages for fsx test case
535 Fix caching data integrity bug when extending file size especially when no
536 oplock on file. Fix spurious logging of valid already parsed mount options
537 that are parsed outside of the cifs vfs such as nosuid.
542 Connect to server when port number override not specified, and tcp port
543 unitialized. Reset search to restart at correct file when kernel routine
544 filldir returns error during large directory searches (readdir).
548 Fix caching problem when files opened by multiple clients in which
549 page cache could contain stale data, and write through did
550 not occur often enough while file was still open when read ahead
551 (read oplock) not allowed. Treat "sep=" when first mount option
552 as an override of comma as the default separator between mount
557 Allow passwords longer than 16 bytes. Allow null password string.
561 Gracefully clean up failed mounts when attempting to mount to servers such as
562 Windows 98 that terminate tcp sessions during protocol negotiation. Handle
563 embedded commas in mount parsing of passwords.
567 Invalidate local inode cached pages on oplock break and when last file
568 instance is closed so that the client does not continue using stale local
569 copy rather than later modified server copy of file. Do not reconnect
570 when server drops the tcp session prematurely before negotiate
571 protocol response. Fix oops in reopen_file when dentry freed. Allow
572 the support for CIFS Unix Extensions to be disabled via proc interface.
576 Fix hang in commit_write during reconnection of open files under heavy load.
577 Fix unload_nls oops in a mount failure path. Serialize writes to same socket
578 which also fixes any possible races when cifs signatures are enabled in SMBs
579 being sent out of signature sequence number order.
583 Fix byte range locking bug (endian problem) causing bad offset and
588 Fix oops (in send_sig) caused by CIFS unmount code trying to
589 wake up the demultiplex thread after it had exited. Do not log
590 error on harmless oplock release of closed handle.
594 Fix unsafe global variable usage and password hash failure on gcc 3.3.1
595 Fix problem reconnecting secondary mounts to same server after session
596 failure. Fix invalid dentry - race in mkdir when directory gets created
597 by another client between the lookup and mkdir.
601 Fix to list processing in reopen_files. Fix reconnection when server hung
602 but tcpip session still alive. Set proper timeout on socket read.
606 Add missing mount options including iocharset. SMP fixes in write and open.
607 Fix errors in reconnecting after TCP session failure. Fix module unloading
608 of default nls codepage
612 Active smb transactions should never go negative (fix double FreeXid). Fix
613 list processing in file routines. Check return code on kmalloc in open.
614 Fix spinlock usage for SMP.
618 Fix oops in reopen_files when invalid dentry. drop dentry on server rename
619 and on revalidate errors. Fix cases where pid is now tgid. Fix return code
620 on create hard link when server does not support them.
624 Fix scheduling while atomic error in getting inode info on newly created file.
625 Fix truncate of existing files opened with O_CREAT but not O_TRUNC set.
629 Fix oops on write to dead tcp session. Remove error log write for case when file open
630 O_CREAT but not O_EXCL
634 Fix non-POSIX behavior on rename of open file and delete of open file by taking
635 advantage of trans2 SetFileInfo rename facility if available on target server.
636 Retry on ENOSPC and EAGAIN socket errors.
640 Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix
641 allocation size miscalculation. After oplock token lost do not read through
646 Fix oops on empty file readahead. Fix for file size handling for locally cached files.
650 Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files
651 during auto reconnection to server after server recovered from failure.
655 Finish support for Linux 2.5 open/create changes, which removes the
656 redundant NTCreate/QPathInfo/close that was sent during file create.
657 Enable oplock by default. Enable packet signing by default (needed to
658 access many recent Windows servers)
662 Fix oops when mounting to long server names caused by inverted parms to kmalloc.
663 Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
664 we will choose a cifs user session (smb uid) that better matches the local
665 uid if a) the mount uid does not match the current uid and b) we have another
666 session to the same server (ip address) for a different mount which
667 matches the current local uid.
671 Add support for mknod of block or character devices. Fix oplock
672 code (distributed caching) to properly send response to oplock
677 Finish up CIFS packet digital signing for the default
678 NTLM security case. This should help Windows 2003
679 network interoperability since it is common for
680 packet signing to be required now. Fix statfs (stat -f)
681 which recently started returning errors due to
682 invalid value (-1 instead of 0) being set in the
683 struct kstatfs f_ffiles field.
687 Fix oops on stopping oplock thread when removing cifs when
692 Fix mount options for ro (readonly), uid, gid and file and directory mode.
696 Fix errors displayed on failed mounts to be more understandable.
697 Fixed various incorrect or misleading smb to posix error code mappings.
701 Fix display of NTFS DFS junctions to display as symlinks.
702 They are the network equivalent. Fix oops in
703 cifs_partialpagewrite caused by missing spinlock protection
704 of openfile linked list. Allow writebehind caching errors to
705 be returned to the application at file close.
709 Clean up options displayed in /proc/mounts by show_options to
710 be more consistent with other filesystems.
714 Fix delete of readonly file to Windows servers. Reflect
715 presence or absence of read only dos attribute in mode
716 bits for servers that do not support CIFS Unix extensions.
717 Fix shortened results on readdir of large directories to
718 servers supporting CIFS Unix extensions (caused by
719 incorrect resume key).
723 Fix truncate bug (set file size) that could cause hangs e.g. running fsx
727 unload nls if mount fails.
731 Add resume key support to search (readdir) code to workaround
732 Windows bug. Add /proc/fs/cifs/LookupCacheEnable which
733 allows disabling caching of attribute information for
738 Add more oplock handling (distributed caching code). Remove
739 dead code. Remove excessive stack space utilization from
744 Fix oops in get dfs referral (triggered when null path sent in to
745 mount). Add support for overriding rsize at mount time.
749 Fix buffer overrun in readdir which caused intermittent kernel oopses.
750 Fix writepage code to release kmap on write data. Allow "-ip=" new
751 mount option to be passed in on parameter distinct from the first part
752 (server name portion of) the UNC name. Allow override of the
753 tcp port of the target server via new mount option "-port="
757 Fix search handle leak on rewind. Fix setuid and gid so that they are
758 reflected in the local inode immediately. Cleanup of whitespace
759 to make 2.4 and 2.5 versions more consistent.
764 Fix signal sending so that captive thread (cifsd) exits on umount
765 (which was causing the warning in kmem_cache_free of the request buffers
766 at rmmod time). This had broken as a sideeffect of the recent global
767 kernel change to daemonize. Fix memory leak in readdir code which
768 showed up in "ls -R" (and applications that did search rewinding).
772 Reconnect tids and fids after session reconnection (still do not
773 reconnect byte range locks though). Fix problem caching
774 lookup information for directory inodes, improving performance,
775 especially in deep directory trees. Fix various build warnings.
779 Finish fixes to commit write for caching/readahead consistency. fsx
780 now works to Samba servers. Fix oops caused when readahead
781 was interrupted by a signal.
785 Fix data corruption (in partial page after truncate) that caused fsx to
786 fail to Windows servers. Cleaned up some extraneous error logging in
787 common error paths. Add generic sendfile support.
791 Fix memory leak in AllocMidQEntry.
792 Finish reconnection logic, so connection with server can be dropped
793 (or server rebooted) and the cifs client will reconnect.
797 Fix temporary socket leak when bad userid or password specified
798 (or other SMBSessSetup failure). Increase maximum buffer size to slightly
799 over 16K to allow negotiation of up to Samba and Windows server default read
800 sizes. Add support for readpages
804 Fix oops when username not passed in on mount. Extensive fixes and improvements
805 to error logging (strip redundant newlines, change debug macros to ensure newline
806 passed in and to be more consistent). Fix writepage wrong file handle problem,
807 a readonly file handle could be incorrectly used to attempt to write out
808 file updates through the page cache to multiply open files. This could cause
809 the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
810 shares to the same Windows server when using different usernames
811 (doing this to Samba servers worked but Windows was rejecting it) - now it is
812 possible to use different userids when connecting to the same server from a
813 Linux client. Fix oops when treeDisconnect called during unmount on
814 previously freed socket.
818 Fix oops in readpages caused by not setting address space operations in inode in
823 Includes support for deleting of open files and renaming over existing files (per POSIX
824 requirement). Add readlink support for Windows junction points (directory symlinks).
828 Changed read and write to go through pagecache. Added additional address space operations.
829 Memory mapped operations now working.
833 Added writepage code for additional memory mapping support. Fixed leak in xids causing
834 the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
835 every stat call. Additional formatting cleanup.
839 Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
843 Fixes from Zwane Mwaikambo for adding missing return code checking in a few places.
844 Also included a modified version of his fix to protect global list manipulation of
845 the smb session and tree connection and mid related global variables.
849 Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
850 changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
851 buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
855 More stylistic updates to better match kernel style. Add additional statistics
856 for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
857 and CIFS Packet Signing enablement.
861 Replace call to sleep_on with safer wait_on_event.
862 Make stylistic changes to better match kernel style recommendations.
863 Remove most typedef usage (except for the PDUs themselves).
867 Update mount so the -unc mount option is no longer required (the ip address can be specified
868 in a UNC style device name. Implementation of readpage/writepage started.
872 Fix intermittent problem with incorrect smb header checking on badly
873 fragmented tcp responses
877 Fixes to setting of allocation size and file size.
881 Various 2.5.38 fixes. Now works on 2.5.38
885 Prepare for 2.5 kernel merge. Remove ifdefs.
889 Socket buffer management fixes. Fix dual free.
893 Various big endian fixes for hardlinks and symlinks and also for dfs.
897 Various big endian fixes for servers with Unix extensions such as Samba
901 Various FindNext fixes for incorrect filenames on large directory searches on big endian
902 clients. basic posix file i/o tests now work on big endian machines, not just le
906 SessionSetup and NegotiateProtocol now work from Big Endian machines.
907 Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older
908 versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7).
912 Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
913 files now return the correct number of links on fstat as they are repeatedly linked and unlinked.
917 Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
918 session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
919 Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
920 (which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).
924 Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
925 it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
929 Rewrote much of connection and mount/unmount logic to handle bugs with
930 multiple uses to same share, multiple users to same server etc.
934 Fixed major problem with dentry corruption (missing call to dput)
938 Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
939 Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
940 although corresponding function not fully implemented in the vfs yet
944 Fixed dentry caching bug, misc. cleanup
948 Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
949 on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
950 Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
954 Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
955 and tested against Samba 2.2.5
960 1) Fixed lockrange to be correct (it was one byte too short)
962 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
963 show range as locked when there is a conflict with an existing lock.
965 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
966 in most cases. Eventually will offer optional ability to query server for the correct perms.
968 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
969 but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
972 4) Fixed error logging of valid mount options
974 5) Removed logging of password field.
976 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
977 and cleaned them up and made them more consistent with other cifs functions.
979 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
980 (with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
981 nor is the symlink support using the Unix extensions
983 8) Started adding the readlink and follow_link code
