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