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