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