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