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