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