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