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