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