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