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