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