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