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).
12 Various fixes to make delete of open files behavior more predictable
13 (when delete of an open file fails we mark the file as "delete-on-close"
14 in a way that more servers accept, but only if we can first rename the
15 file to a temporary name). Add experimental support for more safely
16 handling fcntl(F_SETLEASE). Convert cifs to using blocking tcp
17 sends, and also let tcp autotune the socket send and receive buffers.
18 This reduces the number of EAGAIN errors returned by TCP/IP in
19 high stress workloads (and the number of retries on socket writes
20 when sending large SMBWriteX requests). Fix case in which a portion of
21 data can in some cases not get written to the file on the server before the
22 file is closed. Fix DFS parsing to properly handle path consumed field,
23 and to handle certain codepage conversions better. Fix mount and
24 umount race that can cause oops in mount or umount or reconnect.
28 Fix premature write failure on congested networks (we would give up
29 on EAGAIN from the socket too quickly on large writes).
30 Cifs_mkdir and cifs_create now respect the setgid bit on parent dir.
31 Fix endian problems in acl (mode from/to cifs acl) on bigendian
32 architectures. Fix problems with preserving timestamps on copying open
33 files (e.g. "cp -a") to Windows servers. For mkdir and create honor setgid bit
34 on parent directory when server supports Unix Extensions but not POSIX
35 create. Update cifs.upcall version to handle new Kerberos sec flags
36 (this requires update of cifs.upcall program from Samba). Fix memory leak
37 on dns_upcall (resolving DFS referralls). Fix plain text password
38 authentication (requires setting SecurityFlags to 0x30030 to enable
39 lanman and plain text though). Fix writes to be at correct offset when
40 file is open with O_APPEND and file is on a directio (forcediretio) mount.
41 Fix bug in rewinding readdir directory searches. Add nodfs mount option.
45 DFS support added (Microsoft Distributed File System client support needed
46 for referrals which enable a hierarchical name space among servers).
47 Disable temporary caching of mode bits to servers which do not support
48 storing of mode (e.g. Windows servers, when client mounts without cifsacl
49 mount option) and add new "dynperm" mount option to enable temporary caching
50 of mode (enable old behavior). Fix hang on mount caused when server crashes
51 tcp session during negotiate protocol.
55 Fix oops on second mount to server when null auth is used.
56 Enable experimental Kerberos support. Return writebehind errors on flush
57 and sync so that events like out of disk space get reported properly on
58 cached files. Fix setxattr failure to certain Samba versions. Fix mount
59 of second share to disconnected server session (autoreconnect on this).
60 Add ability to modify cifs acls for handling chmod (when mounted with
61 cifsacl flag). Fix prefixpath path separator so we can handle mounts
62 with prefixpaths longer than one directory (one path component) when
63 mounted to Windows servers. Fix slow file open when cifsacl
64 enabled. Fix memory leak in FindNext when the SMB call returns -EBADF.
69 Fix memory leak in statfs when mounted to very old servers (e.g.
70 Windows 9x). Add new feature "POSIX open" which allows servers
71 which support the current POSIX Extensions to provide better semantics
72 (e.g. delete for open files opened with posix open). Take into
73 account umask on posix mkdir not just older style mkdir. Add
74 ability to mount to IPC$ share (which allows CIFS named pipes to be
75 opened, read and written as if they were files). When 1st tree
76 connect fails (e.g. due to signing negotiation failure) fix
77 leak that causes cifsd not to stop and rmmod to fail to cleanup
78 cifs_request_buffers pool. Fix problem with POSIX Open/Mkdir on
79 bigendian architectures. Fix possible memory corruption when
80 EAGAIN returned on kern_recvmsg. Return better error if server
81 requires packet signing but client has disabled it. When mounted
82 with cifsacl mount option - mode bits are approximated based
83 on the contents of the ACL of the file or directory. When cifs
84 mount helper is missing convert make sure that UNC name
85 has backslash (not forward slash) between ip address of server
90 Fix NTLMv2 signing. NFS server mounted over cifs works (if cifs mount is
91 done with "serverino" mount option). Add support for POSIX Unlink
92 (helps with certain sharing violation cases when server such as
93 Samba supports newer POSIX CIFS Protocol Extensions). Add "nounix"
94 mount option to allow disabling the CIFS Unix Extensions for just
95 that mount. Fix hang on spinlock in find_writable_file (race when
96 reopening file after session crash). Byte range unlock request to
97 windows server could unlock more bytes (on server copy of file)
98 than intended if start of unlock request is well before start of
99 a previous byte range lock that we issued.
103 IPv6 support. Enable ipv6 addresses to be passed on mount (put the ipv6
104 address after the "ip=" mount option, at least until mount.cifs is fixed to
105 handle DNS host to ipv6 name translation). Accept override of uid or gid
106 on mount even when Unix Extensions are negotiated (it used to be ignored
107 when Unix Extensions were ignored). This allows users to override the
108 default uid and gid for files when they are certain that the uids or
109 gids on the server do not match those of the client. Make "sec=none"
110 mount override username (so that null user connection is attempted)
111 to match what documentation said. Support for very large reads, over 127K,
112 available to some newer servers (such as Samba 3.0.26 and later but
113 note that it also requires setting CIFSMaxBufSize at module install
114 time to a larger value which may hurt performance in some cases).
115 Make sign option force signing (or fail if server does not support it).
119 Fix mtime bouncing around from local idea of last write times to remote time.
120 Fix hang (in i_size_read) when simultaneous size update of same remote file
121 on smp system corrupts sequence number. Do not reread unnecessarily partial page
122 (which we are about to overwrite anyway) when writing out file opened rw.
123 When DOS attribute of file on non-Unix server's file changes on the server side
124 from read-only back to read-write, reflect this change in default file mode
125 (we had been leaving a file's mode read-only until the inode were reloaded).
126 Allow setting of attribute back to ATTR_NORMAL (removing readonly dos attribute
127 when archive dos attribute not set and we are changing mode back to writeable
128 on server which does not support the Unix Extensions). Remove read only dos
129 attribute on chmod when adding any write permission (ie on any of
130 user/group/other (not all of user/group/other ie 0222) when
131 mounted to windows. Add support for POSIX MkDir (slight performance
132 enhancement and eliminates the network race between the mkdir and set
133 path info of the mode).
138 Fix oops in list_del during mount caused by unaligned string.
139 Fix file corruption which could occur on some large file
140 copies caused by writepages page i/o completion bug.
141 Seek to SEEK_END forces check for update of file size for non-cached
142 files. Allow file size to be updated on remote extend of locally open,
143 non-cached file. Fix reconnect to newer Samba servers (or other servers
144 which support the CIFS Unix/POSIX extensions) so that we again tell the
145 server the Unix/POSIX cifs capabilities which we support (SetFSInfo).
146 Add experimental support for new POSIX Open/Mkdir (which returns
147 stat information on the open, and allows setting the mode).
151 Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
152 Allow null user to be specified on mount ("username="). Do not return
153 EINVAL on readdir when filldir fails due to overwritten blocksize
154 (fixes FC problem). Return error in rename 2nd attempt retry (ie report
155 if rename by handle also fails, after rename by path fails, we were
156 not reporting whether the retry worked or not). Fix NTLMv2 to
157 work to Windows servers (mount with option "sec=ntlmv2").
161 Do not time out lockw calls when using posix extensions. Do not
162 time out requests if server still responding reasonably fast
163 on requests on other threads. Improve POSIX locking emulation,
164 (lock cancel now works, and unlock of merged range works even
165 to Windows servers now). Fix oops on mount to lanman servers
166 (win9x, os/2 etc.) when null password. Do not send listxattr
167 (SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
168 problem (instantiate inodes/dentries in right order for readdir).
172 Rewritten sessionsetup support, including support for legacy SMB
173 session setup needed for OS/2 and older servers such as Windows 95 and 98.
174 Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
175 so we can do search (ls etc.) to OS/2. Do not send NTCreateX
176 or recent levels of FindFirst unless server says it supports NT SMBs
177 (instead use legacy equivalents from LANMAN dialect). Fix to allow
178 NTLMv2 authentication support (now can use stronger password hashing
179 on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
180 Allow override of global cifs security flags on mount via "sec=" option(s).
184 POSIX locking to servers which support CIFS POSIX Extensions
185 (disabled by default controlled by proc/fs/cifs/Experimental).
186 Handle conversion of long share names (especially Asian languages)
187 to Unicode during mount. Fix memory leak in sess struct on reconnect.
188 Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
189 cifs open which helps rare case when setpathinfo fails or server does
194 Fix slow oplock break when mounted to different servers at the same time and
195 the tids match and we try to find matching fid on wrong server. Fix read
196 looping when signing required by server (2.6.16 kernel only). Fix readdir
197 vs. rename race which could cause each to hang. Return . and .. even
198 if server does not. Allow searches to skip first three entries and
199 begin at any location. Fix oops in find_writeable_file.
203 Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
204 configure stronger authentication. Fix sfu symlinks so they can
205 be followed (not just recognized). Fix wraparound of bcc on
206 read responses when buffer size over 64K and also fix wrap of
207 max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
208 cifs_user_read and cifs_readpages (when EAGAIN on send of smb
209 on socket is returned over and over). Add POSIX (advisory) byte range
210 locking support (requires server with newest CIFS UNIX Extensions
211 to the protocol implemented). Slow down negprot slightly in port 139
212 RFC1001 case to give session_init time on buggy servers.
216 Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
217 of readpages by eliminating one extra memcpy. Allow update of file size
218 from remote server even if file is open for write as long as mount is
219 directio. Recognize share mode security and send NTLM encrypted password
220 on tree connect if share mode negotiated.
224 Defer close of a file handle slightly if pending writes depend on that handle
225 (this reduces the EBADF bad file handle errors that can be logged under heavy
226 stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
227 Fix SFU style symlinks and mknod needed for servers which do not support the
228 CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
229 dentries so files that the client sees as deleted but that later get created
230 on the server will be recognized. Add client side permission check on setattr.
231 Timeout stuck requests better (where server has never responded or sent corrupt
236 Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
237 to be smaller at first (but increasing) so large write performance performance
238 over GigE is better. Do not hang thread on illegal byte range lock response
239 from Windows (Windows can send an RFC1001 size which does not match smb size) by
240 allowing an SMBs TCP length to be up to a few bytes longer than it should be.
241 wsize and rsize can now be larger than negotiated buffer size if server
242 supports large readx/writex, even when directio mount flag not specified.
243 Write size will in many cases now be 16K instead of 4K which greatly helps
244 file copy performance on lightly loaded networks. Fix oops in dnotify
245 when experimental config flag enabled. Make cifsFYI more granular.
249 Fix readdir caching when unlink removes file in current search buffer,
250 and this is followed by a rewind search to just before the deleted entry.
251 Do not attempt to set ctime unless atime and/or mtime change requested
252 (most servers throw it away anyway). Fix length check of received smbs
253 to be more accurate. Fix big endian problem with mapchars mount option,
254 and with a field returned by statfs.
258 Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
259 For these older servers, add option for passing netbios name of server in
260 on mount (servernetbiosname). Add suspend support for power management, to
261 avoid cifsd thread preventing software suspend from working.
262 Add mount option for disabling the default behavior of sending byte range lock
263 requests to the server (necessary for certain applications which break with
264 mandatory lock behavior such as Evolution), and also mount option for
265 requesting case insensitive matching for path based requests (requesting
266 case sensitive is the default).
270 Add writepage performance improvements. Fix path name conversions
271 for long filenames on mounts which were done with "mapchars" mount option
272 specified. Ensure multiplex ids do not collide. Fix case in which
273 rmmod can oops if done soon after last unmount. Fix truncated
274 search (readdir) output when resume filename was a long filename.
275 Fix filename conversion when mapchars mount option was specified and
276 filename was a long filename.
280 Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
281 Do not oops if root user kills cifs oplock kernel thread or
282 kills the cifsd thread (NB: killing the cifs kernel threads is not
283 recommended, unmount and rmmod cifs will kill them when they are
284 no longer needed). Fix readdir to ASCII servers (ie older servers
285 which do not support Unicode) and also require asterisk.
286 Fix out of memory case in which data could be written one page
287 off in the page cache.
291 Fix caching problem, in which readdir of directory containing a file
292 which was cached could cause the file's time stamp to be updated
293 without invalidating the readahead data (so we could get stale
294 file data on the client for that file even as the server copy changed).
295 Cleanup response processing so cifsd can not loop when abnormally
301 Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
302 transact response for an SMB request and search entry split across two frames.
303 Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
304 as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
305 unless server explicitly claims to support them in CIFS Unix extensions
306 POSIX ACL capability bit. Fix packet signing when multiuser mounting with
307 different users from the same client to the same server. Fix oops in
308 cifs_close. Add mount option for remapping reserved characters in
309 filenames (also allow recognizing files with created by SFU which have any
310 of these seven reserved characters, except backslash, to be recognized).
311 Fix invalid transact2 message (we were sometimes trying to interpret
312 oplock breaks as SMB responses). Add ioctl for checking that the
313 current uid matches the uid of the mounter (needed by umount.cifs).
314 Reduce the number of large buffer allocations in cifs response processing
315 (significantly reduces memory pressure under heavy stress with multiple
316 processes accessing the same server at the same time).
320 Fix updates of DOS attributes and time fields so that files on NT4 servers
321 do not get marked delete on close. Display sizes of cifs buffer pools in
322 cifs stats. Fix oops in unmount when cifsd thread being killed by
323 shutdown. Add generic readv/writev and aio support. Report inode numbers
324 consistently in readdir and lookup (when serverino mount option is
325 specified use the inode number that the server reports - for both lookup
326 and readdir, otherwise by default the locally generated inode number is used
327 for inodes created in either path since servers are not always able to
328 provide unique inode numbers when exporting multiple volumes from under one
333 Allow new nouser_xattr mount parm to disable xattr support for user namespace.
334 Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
335 (mostly affects NT4 servers) by retry with handle based network operation.
336 Add new POSIX Query FS Info for returning statfs info more accurately.
337 Handle passwords with multiple commas in them.
341 Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
342 Fix capabilities flags for large readx so as to allow reads larger than 64K.
346 Add module init parm for large SMB buffer size (to allow it to be changed
347 from its default of 16K) which is especially useful for large file copy
348 when mounting with the directio mount option. Fix oops after
349 returning from mount when experimental ExtendedSecurity enabled and
350 SpnegoNegotiated returning invalid error. Fix case to retry better when
351 peek returns from 1 to 3 bytes on socket which should have more data.
352 Fixed path based calls (such as cifs lookup) to handle path names
353 longer than 530 (now can handle PATH_MAX). Fix pass through authentication
354 from Samba server to DC (Samba required dummy LM password).
358 Turn off DNOTIFY (directory change notification support) by default
359 (unless built with the experimental flag) to fix hang with KDE
360 file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
361 waiting on an SMB response) in SendReceive when session dies but
362 reconnects quickly from another task. Add module init parms for
363 minimum number of large and small network buffers in the buffer pools,
364 and for the maximum number of simultaneous requests.
368 Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
369 and other POSIX CIFS compliant servers. Fix error mapping for getfacl
370 to EOPNOTSUPP when server does not support posix acls on the wire. Fix
371 improperly zeroed buffer in CIFS Unix extensions set times call.
375 Fix internationalization problem in cifs readdir with filenames that map to
376 longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
377 for readdir to netapp servers. Fix search rewind (seek into readdir to return
378 non-consecutive entries). Do not do readdir when server negotiates
379 buffer size to small to fit filename. Add support for reading POSIX ACLs from
380 the server (add also acl and noacl mount options).
384 Optionally allow using server side inode numbers, rather than client generated
385 ones by specifying mount option "serverino" - this is required for some apps
386 to work which double check hardlinked files and have persistent inode numbers.
390 Multiple bigendian fixes. On little endian systems (for reconnect after
391 network failure) fix tcp session reconnect code so we do not try first
392 to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
393 as directories rather than symlinks because we can do follow link on them.
397 Add config option to enable XATTR (extended attribute) support, mapping
398 xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
399 minor fixes pointed out by the Stanford SWAT checker (mostly missing
400 or out of order NULL pointer checks in little used error paths).
404 Add new mount parm to control whether mode check (generic_permission) is done
405 on the client. If Unix extensions are enabled and the uids on the client
406 and server do not match, client permission checks are meaningless on
407 server uids that do not exist on the client (this does not affect the
408 normal ACL check which occurs on the server). Fix default uid
409 on mknod to match create and mkdir. Add optional mount parm to allow
410 override of the default uid behavior (in which the server sets the uid
411 and gid of newly created files). Normally for network filesystem mounts
412 user want the server to set the uid/gid on newly created files (rather than
413 using uid of the client processes you would in a local filesystem).
417 Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
418 info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
419 (in build_wildcard_path_from_dentry). Fix mknod to pass type field
420 (block/char/fifo) properly. Remove spurious mount warning log entry when
421 credentials passed as mount argument. Set major/minor device number in
422 inode for block and char devices when unix extensions enabled.
426 Fix /proc/fs/cifs/Stats and DebugData display to handle larger
427 amounts of return data. Properly limit requests to MAX_REQ (50
428 is the usual maximum active multiplex SMB/CIFS requests per server).
429 Do not kill cifsd (and thus hurt the other SMB session) when more than one
430 session to the same server (but with different userids) exists and one
431 of the two user's smb sessions is being removed while leaving the other.
432 Do not loop reconnecting in cifsd demultiplex thread when admin
433 kills the thread without going through unmount.
437 Do not rename hardlinked files (since that should be a noop). Flush
438 cached write behind data when reopening a file after session abend,
439 except when already in write. Grab per socket sem during reconnect
440 to avoid oops in sendmsg if overlapping with reconnect. Do not
441 reset cached inode file size on readdir for files open for write on
447 Update number of blocks in file so du command is happier (in Linux a fake
448 blocksize of 512 is required for calculating number of blocks in inode).
449 Fix prepare write of partial pages to read in data from server if possible.
450 Fix race on tcpStatus field between unmount and reconnection code, causing
451 cifsd process sometimes to hang around forever. Improve out of memory
452 checks in cifs_filldir
456 Fix incorrect file size in file handle based setattr on big endian hardware.
457 Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
458 and closing file structs in writepage/partialpagewrite. Add statistics
459 for each mounted share (new menuconfig option). Fix endianness problem in
460 volume information displayed in /proc/fs/cifs/DebugData (only affects
461 affects big endian architectures). Prevent renames while constructing
462 path names for open, mkdir and rmdir.
466 Change to mempools for alloc smb request buffers and multiplex structs
467 to better handle low memory problems (and potential deadlocks).
471 Fix incomplete listings of large directories on Samba servers when Unix
472 extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
473 rename deadlock when writing out dirty pages at same time.
477 Fix open of files in which O_CREATE can cause the mode to change in
478 some cases. Fix case in which retry of write overlaps file close.
479 Fix PPC64 build error. Reduce excessive stack usage in smb password
480 hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
484 Fixes for large file copy, signal handling, socket retry, buffer
485 allocation and low memory situations.
489 Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
490 also now allowing support for specifying client netbiosname. NT4 support added.
494 Fix reconnection (and certain failed mounts) to properly wake up the
495 blocked users thread so it does not seem hung (in some cases was blocked
496 until the cifs receive timeout expired). Fix spurious error logging
497 to kernel log when application with open network files killed.
501 Fix /proc/fs module unload warning message (that could be logged
502 to the kernel log). Fix intermittent failure in connectathon
503 test7 (hardlink count not immediately refreshed in case in which
504 inode metadata can be incorrectly kept cached when time near zero)
508 Allow file_mode and dir_mode (specified at mount time) to be enforced
509 locally (the server already enforced its own ACLs too) for servers
510 that do not report the correct mode (do not support the
511 CIFS Unix Extensions).
515 Fix some small memory leaks in some unmount error paths. Fix major leak
516 of cache pages in readpages causing multiple read oriented stress
517 testcases (including fsx, and even large file copy) to fail over time.
521 Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
522 This allows files that differ only in case and improves performance of file
523 creation and file open to such servers. Fix semaphore conflict which causes
524 slow delete of open file to Samba (which unfortunately can cause an oplock
525 break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
529 fixes to cifs_readpages for fsx test case
533 Fix caching data integrity bug when extending file size especially when no
534 oplock on file. Fix spurious logging of valid already parsed mount options
535 that are parsed outside of the cifs vfs such as nosuid.
540 Connect to server when port number override not specified, and tcp port
541 unitialized. Reset search to restart at correct file when kernel routine
542 filldir returns error during large directory searches (readdir).
546 Fix caching problem when files opened by multiple clients in which
547 page cache could contain stale data, and write through did
548 not occur often enough while file was still open when read ahead
549 (read oplock) not allowed. Treat "sep=" when first mount option
550 as an override of comma as the default separator between mount
555 Allow passwords longer than 16 bytes. Allow null password string.
559 Gracefully clean up failed mounts when attempting to mount to servers such as
560 Windows 98 that terminate tcp sessions during protocol negotiation. Handle
561 embedded commas in mount parsing of passwords.
565 Invalidate local inode cached pages on oplock break and when last file
566 instance is closed so that the client does not continue using stale local
567 copy rather than later modified server copy of file. Do not reconnect
568 when server drops the tcp session prematurely before negotiate
569 protocol response. Fix oops in reopen_file when dentry freed. Allow
570 the support for CIFS Unix Extensions to be disabled via proc interface.
574 Fix hang in commit_write during reconnection of open files under heavy load.
575 Fix unload_nls oops in a mount failure path. Serialize writes to same socket
576 which also fixes any possible races when cifs signatures are enabled in SMBs
577 being sent out of signature sequence number order.
581 Fix byte range locking bug (endian problem) causing bad offset and
586 Fix oops (in send_sig) caused by CIFS unmount code trying to
587 wake up the demultiplex thread after it had exited. Do not log
588 error on harmless oplock release of closed handle.
592 Fix unsafe global variable usage and password hash failure on gcc 3.3.1
593 Fix problem reconnecting secondary mounts to same server after session
594 failure. Fix invalid dentry - race in mkdir when directory gets created
595 by another client between the lookup and mkdir.
599 Fix to list processing in reopen_files. Fix reconnection when server hung
600 but tcpip session still alive. Set proper timeout on socket read.
604 Add missing mount options including iocharset. SMP fixes in write and open.
605 Fix errors in reconnecting after TCP session failure. Fix module unloading
606 of default nls codepage
610 Active smb transactions should never go negative (fix double FreeXid). Fix
611 list processing in file routines. Check return code on kmalloc in open.
612 Fix spinlock usage for SMP.
616 Fix oops in reopen_files when invalid dentry. drop dentry on server rename
617 and on revalidate errors. Fix cases where pid is now tgid. Fix return code
618 on create hard link when server does not support them.
622 Fix scheduling while atomic error in getting inode info on newly created file.
623 Fix truncate of existing files opened with O_CREAT but not O_TRUNC set.
627 Fix oops on write to dead tcp session. Remove error log write for case when file open
628 O_CREAT but not O_EXCL
632 Fix non-POSIX behavior on rename of open file and delete of open file by taking
633 advantage of trans2 SetFileInfo rename facility if available on target server.
634 Retry on ENOSPC and EAGAIN socket errors.
638 Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix
639 allocation size miscalculation. After oplock token lost do not read through
644 Fix oops on empty file readahead. Fix for file size handling for locally cached files.
648 Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files
649 during auto reconnection to server after server recovered from failure.
653 Finish support for Linux 2.5 open/create changes, which removes the
654 redundant NTCreate/QPathInfo/close that was sent during file create.
655 Enable oplock by default. Enable packet signing by default (needed to
656 access many recent Windows servers)
660 Fix oops when mounting to long server names caused by inverted parms to kmalloc.
661 Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
662 we will choose a cifs user session (smb uid) that better matches the local
663 uid if a) the mount uid does not match the current uid and b) we have another
664 session to the same server (ip address) for a different mount which
665 matches the current local uid.
669 Add support for mknod of block or character devices. Fix oplock
670 code (distributed caching) to properly send response to oplock
675 Finish up CIFS packet digital signing for the default
676 NTLM security case. This should help Windows 2003
677 network interoperability since it is common for
678 packet signing to be required now. Fix statfs (stat -f)
679 which recently started returning errors due to
680 invalid value (-1 instead of 0) being set in the
681 struct kstatfs f_ffiles field.
685 Fix oops on stopping oplock thread when removing cifs when
690 Fix mount options for ro (readonly), uid, gid and file and directory mode.
694 Fix errors displayed on failed mounts to be more understandable.
695 Fixed various incorrect or misleading smb to posix error code mappings.
699 Fix display of NTFS DFS junctions to display as symlinks.
700 They are the network equivalent. Fix oops in
701 cifs_partialpagewrite caused by missing spinlock protection
702 of openfile linked list. Allow writebehind caching errors to
703 be returned to the application at file close.
707 Clean up options displayed in /proc/mounts by show_options to
708 be more consistent with other filesystems.
712 Fix delete of readonly file to Windows servers. Reflect
713 presence or absence of read only dos attribute in mode
714 bits for servers that do not support CIFS Unix extensions.
715 Fix shortened results on readdir of large directories to
716 servers supporting CIFS Unix extensions (caused by
717 incorrect resume key).
721 Fix truncate bug (set file size) that could cause hangs e.g. running fsx
725 unload nls if mount fails.
729 Add resume key support to search (readdir) code to workaround
730 Windows bug. Add /proc/fs/cifs/LookupCacheEnable which
731 allows disabling caching of attribute information for
736 Add more oplock handling (distributed caching code). Remove
737 dead code. Remove excessive stack space utilization from
742 Fix oops in get dfs referral (triggered when null path sent in to
743 mount). Add support for overriding rsize at mount time.
747 Fix buffer overrun in readdir which caused intermittent kernel oopses.
748 Fix writepage code to release kmap on write data. Allow "-ip=" new
749 mount option to be passed in on parameter distinct from the first part
750 (server name portion of) the UNC name. Allow override of the
751 tcp port of the target server via new mount option "-port="
755 Fix search handle leak on rewind. Fix setuid and gid so that they are
756 reflected in the local inode immediately. Cleanup of whitespace
757 to make 2.4 and 2.5 versions more consistent.
762 Fix signal sending so that captive thread (cifsd) exits on umount
763 (which was causing the warning in kmem_cache_free of the request buffers
764 at rmmod time). This had broken as a sideeffect of the recent global
765 kernel change to daemonize. Fix memory leak in readdir code which
766 showed up in "ls -R" (and applications that did search rewinding).
770 Reconnect tids and fids after session reconnection (still do not
771 reconnect byte range locks though). Fix problem caching
772 lookup information for directory inodes, improving performance,
773 especially in deep directory trees. Fix various build warnings.
777 Finish fixes to commit write for caching/readahead consistency. fsx
778 now works to Samba servers. Fix oops caused when readahead
779 was interrupted by a signal.
783 Fix data corruption (in partial page after truncate) that caused fsx to
784 fail to Windows servers. Cleaned up some extraneous error logging in
785 common error paths. Add generic sendfile support.
789 Fix memory leak in AllocMidQEntry.
790 Finish reconnection logic, so connection with server can be dropped
791 (or server rebooted) and the cifs client will reconnect.
795 Fix temporary socket leak when bad userid or password specified
796 (or other SMBSessSetup failure). Increase maximum buffer size to slightly
797 over 16K to allow negotiation of up to Samba and Windows server default read
798 sizes. Add support for readpages
802 Fix oops when username not passed in on mount. Extensive fixes and improvements
803 to error logging (strip redundant newlines, change debug macros to ensure newline
804 passed in and to be more consistent). Fix writepage wrong file handle problem,
805 a readonly file handle could be incorrectly used to attempt to write out
806 file updates through the page cache to multiply open files. This could cause
807 the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
808 shares to the same Windows server when using different usernames
809 (doing this to Samba servers worked but Windows was rejecting it) - now it is
810 possible to use different userids when connecting to the same server from a
811 Linux client. Fix oops when treeDisconnect called during unmount on
812 previously freed socket.
816 Fix oops in readpages caused by not setting address space operations in inode in
821 Includes support for deleting of open files and renaming over existing files (per POSIX
822 requirement). Add readlink support for Windows junction points (directory symlinks).
826 Changed read and write to go through pagecache. Added additional address space operations.
827 Memory mapped operations now working.
831 Added writepage code for additional memory mapping support. Fixed leak in xids causing
832 the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
833 every stat call. Additional formatting cleanup.
837 Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
841 Fixes from Zwane Mwaikambo for adding missing return code checking in a few places.
842 Also included a modified version of his fix to protect global list manipulation of
843 the smb session and tree connection and mid related global variables.
847 Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
848 changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
849 buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
853 More stylistic updates to better match kernel style. Add additional statistics
854 for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
855 and CIFS Packet Signing enablement.
859 Replace call to sleep_on with safer wait_on_event.
860 Make stylistic changes to better match kernel style recommendations.
861 Remove most typedef usage (except for the PDUs themselves).
865 Update mount so the -unc mount option is no longer required (the ip address can be specified
866 in a UNC style device name. Implementation of readpage/writepage started.
870 Fix intermittent problem with incorrect smb header checking on badly
871 fragmented tcp responses
875 Fixes to setting of allocation size and file size.
879 Various 2.5.38 fixes. Now works on 2.5.38
883 Prepare for 2.5 kernel merge. Remove ifdefs.
887 Socket buffer management fixes. Fix dual free.
891 Various big endian fixes for hardlinks and symlinks and also for dfs.
895 Various big endian fixes for servers with Unix extensions such as Samba
899 Various FindNext fixes for incorrect filenames on large directory searches on big endian
900 clients. basic posix file i/o tests now work on big endian machines, not just le
904 SessionSetup and NegotiateProtocol now work from Big Endian machines.
905 Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older
906 versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7).
910 Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
911 files now return the correct number of links on fstat as they are repeatedly linked and unlinked.
915 Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
916 session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
917 Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
918 (which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).
922 Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
923 it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
927 Rewrote much of connection and mount/unmount logic to handle bugs with
928 multiple uses to same share, multiple users to same server etc.
932 Fixed major problem with dentry corruption (missing call to dput)
936 Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
937 Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
938 although corresponding function not fully implemented in the vfs yet
942 Fixed dentry caching bug, misc. cleanup
946 Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
947 on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
948 Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
952 Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
953 and tested against Samba 2.2.5
958 1) Fixed lockrange to be correct (it was one byte too short)
960 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
961 show range as locked when there is a conflict with an existing lock.
963 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
964 in most cases. Eventually will offer optional ability to query server for the correct perms.
966 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
967 but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
970 4) Fixed error logging of valid mount options
972 5) Removed logging of password field.
974 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
975 and cleaned them up and made them more consistent with other cifs functions.
977 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
978 (with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
979 nor is the symlink support using the Unix extensions
981 8) Started adding the readlink and follow_link code
