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.
13 Fix mtime bouncing around from local idea of last write times to remote time.
14 Fix hang (in i_size_read) when simultaneous size update of same remote file
15 on smp system corrupts sequence number. Do not reread unnecessarily partial page
16 (which we are about to overwrite anyway) when writing out file opened rw.
17 When DOS attribute of file on non-Unix server's file changes on the server side
18 from read-only back to read-write, reflect this change in default file mode
19 (we had been leaving a file's mode read-only until the inode were reloaded).
20 Allow setting of attribute back to ATTR_NORMAL (removing readonly dos attribute
21 when archive dos attribute not set and we are changing mode back to writeable
22 on server which does not support the Unix Extensions). Remove read only dos
23 attribute on chmod when adding any write permission (ie on any of
24 user/group/other (not all of user/group/other ie 0222) when
25 mounted to windows. Add support for POSIX MkDir (slight performance
26 enhancement and eliminates the network race between the mkdir and set
27 path info of the mode).
32 Fix oops in list_del during mount caused by unaligned string.
33 Fix file corruption which could occur on some large file
34 copies caused by writepages page i/o completion bug.
35 Seek to SEEK_END forces check for update of file size for non-cached
36 files. Allow file size to be updated on remote extend of locally open,
37 non-cached file. Fix reconnect to newer Samba servers (or other servers
38 which support the CIFS Unix/POSIX extensions) so that we again tell the
39 server the Unix/POSIX cifs capabilities which we support (SetFSInfo).
40 Add experimental support for new POSIX Open/Mkdir (which returns
41 stat information on the open, and allows setting the mode).
45 Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
46 Allow null user to be specified on mount ("username="). Do not return
47 EINVAL on readdir when filldir fails due to overwritten blocksize
48 (fixes FC problem). Return error in rename 2nd attempt retry (ie report
49 if rename by handle also fails, after rename by path fails, we were
50 not reporting whether the retry worked or not). Fix NTLMv2 to
51 work to Windows servers (mount with option "sec=ntlmv2").
55 Do not time out lockw calls when using posix extensions. Do not
56 time out requests if server still responding reasonably fast
57 on requests on other threads. Improve POSIX locking emulation,
58 (lock cancel now works, and unlock of merged range works even
59 to Windows servers now). Fix oops on mount to lanman servers
60 (win9x, os/2 etc.) when null password. Do not send listxattr
61 (SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
62 problem (instantiate inodes/dentries in right order for readdir).
66 Rewritten sessionsetup support, including support for legacy SMB
67 session setup needed for OS/2 and older servers such as Windows 95 and 98.
68 Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
69 so we can do search (ls etc.) to OS/2. Do not send NTCreateX
70 or recent levels of FindFirst unless server says it supports NT SMBs
71 (instead use legacy equivalents from LANMAN dialect). Fix to allow
72 NTLMv2 authentication support (now can use stronger password hashing
73 on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
74 Allow override of global cifs security flags on mount via "sec=" option(s).
78 POSIX locking to servers which support CIFS POSIX Extensions
79 (disabled by default controlled by proc/fs/cifs/Experimental).
80 Handle conversion of long share names (especially Asian languages)
81 to Unicode during mount. Fix memory leak in sess struct on reconnect.
82 Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
83 cifs open which helps rare case when setpathinfo fails or server does
88 Fix slow oplock break when mounted to different servers at the same time and
89 the tids match and we try to find matching fid on wrong server. Fix read
90 looping when signing required by server (2.6.16 kernel only). Fix readdir
91 vs. rename race which could cause each to hang. Return . and .. even
92 if server does not. Allow searches to skip first three entries and
93 begin at any location. Fix oops in find_writeable_file.
97 Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
98 configure stronger authentication. Fix sfu symlinks so they can
99 be followed (not just recognized). Fix wraparound of bcc on
100 read responses when buffer size over 64K and also fix wrap of
101 max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
102 cifs_user_read and cifs_readpages (when EAGAIN on send of smb
103 on socket is returned over and over). Add POSIX (advisory) byte range
104 locking support (requires server with newest CIFS UNIX Extensions
105 to the protocol implemented). Slow down negprot slightly in port 139
106 RFC1001 case to give session_init time on buggy servers.
110 Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
111 of readpages by eliminating one extra memcpy. Allow update of file size
112 from remote server even if file is open for write as long as mount is
113 directio. Recognize share mode security and send NTLM encrypted password
114 on tree connect if share mode negotiated.
118 Defer close of a file handle slightly if pending writes depend on that handle
119 (this reduces the EBADF bad file handle errors that can be logged under heavy
120 stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
121 Fix SFU style symlinks and mknod needed for servers which do not support the
122 CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
123 dentries so files that the client sees as deleted but that later get created
124 on the server will be recognized. Add client side permission check on setattr.
125 Timeout stuck requests better (where server has never responded or sent corrupt
130 Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
131 to be smaller at first (but increasing) so large write performance performance
132 over GigE is better. Do not hang thread on illegal byte range lock response
133 from Windows (Windows can send an RFC1001 size which does not match smb size) by
134 allowing an SMBs TCP length to be up to a few bytes longer than it should be.
135 wsize and rsize can now be larger than negotiated buffer size if server
136 supports large readx/writex, even when directio mount flag not specified.
137 Write size will in many cases now be 16K instead of 4K which greatly helps
138 file copy performance on lightly loaded networks. Fix oops in dnotify
139 when experimental config flag enabled. Make cifsFYI more granular.
143 Fix readdir caching when unlink removes file in current search buffer,
144 and this is followed by a rewind search to just before the deleted entry.
145 Do not attempt to set ctime unless atime and/or mtime change requested
146 (most servers throw it away anyway). Fix length check of received smbs
147 to be more accurate. Fix big endian problem with mapchars mount option,
148 and with a field returned by statfs.
152 Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
153 For these older servers, add option for passing netbios name of server in
154 on mount (servernetbiosname). Add suspend support for power management, to
155 avoid cifsd thread preventing software suspend from working.
156 Add mount option for disabling the default behavior of sending byte range lock
157 requests to the server (necessary for certain applications which break with
158 mandatory lock behavior such as Evolution), and also mount option for
159 requesting case insensitive matching for path based requests (requesting
160 case sensitive is the default).
164 Add writepage performance improvements. Fix path name conversions
165 for long filenames on mounts which were done with "mapchars" mount option
166 specified. Ensure multiplex ids do not collide. Fix case in which
167 rmmod can oops if done soon after last unmount. Fix truncated
168 search (readdir) output when resume filename was a long filename.
169 Fix filename conversion when mapchars mount option was specified and
170 filename was a long filename.
174 Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
175 Do not oops if root user kills cifs oplock kernel thread or
176 kills the cifsd thread (NB: killing the cifs kernel threads is not
177 recommended, unmount and rmmod cifs will kill them when they are
178 no longer needed). Fix readdir to ASCII servers (ie older servers
179 which do not support Unicode) and also require asterisk.
180 Fix out of memory case in which data could be written one page
181 off in the page cache.
185 Fix caching problem, in which readdir of directory containing a file
186 which was cached could cause the file's time stamp to be updated
187 without invalidating the readahead data (so we could get stale
188 file data on the client for that file even as the server copy changed).
189 Cleanup response processing so cifsd can not loop when abnormally
195 Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
196 transact response for an SMB request and search entry split across two frames.
197 Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
198 as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
199 unless server explicitly claims to support them in CIFS Unix extensions
200 POSIX ACL capability bit. Fix packet signing when multiuser mounting with
201 different users from the same client to the same server. Fix oops in
202 cifs_close. Add mount option for remapping reserved characters in
203 filenames (also allow recognizing files with created by SFU which have any
204 of these seven reserved characters, except backslash, to be recognized).
205 Fix invalid transact2 message (we were sometimes trying to interpret
206 oplock breaks as SMB responses). Add ioctl for checking that the
207 current uid matches the uid of the mounter (needed by umount.cifs).
208 Reduce the number of large buffer allocations in cifs response processing
209 (significantly reduces memory pressure under heavy stress with multiple
210 processes accessing the same server at the same time).
214 Fix updates of DOS attributes and time fields so that files on NT4 servers
215 do not get marked delete on close. Display sizes of cifs buffer pools in
216 cifs stats. Fix oops in unmount when cifsd thread being killed by
217 shutdown. Add generic readv/writev and aio support. Report inode numbers
218 consistently in readdir and lookup (when serverino mount option is
219 specified use the inode number that the server reports - for both lookup
220 and readdir, otherwise by default the locally generated inode number is used
221 for inodes created in either path since servers are not always able to
222 provide unique inode numbers when exporting multiple volumes from under one
227 Allow new nouser_xattr mount parm to disable xattr support for user namespace.
228 Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
229 (mostly affects NT4 servers) by retry with handle based network operation.
230 Add new POSIX Query FS Info for returning statfs info more accurately.
231 Handle passwords with multiple commas in them.
235 Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
236 Fix capabilities flags for large readx so as to allow reads larger than 64K.
240 Add module init parm for large SMB buffer size (to allow it to be changed
241 from its default of 16K) which is especially useful for large file copy
242 when mounting with the directio mount option. Fix oops after
243 returning from mount when experimental ExtendedSecurity enabled and
244 SpnegoNegotiated returning invalid error. Fix case to retry better when
245 peek returns from 1 to 3 bytes on socket which should have more data.
246 Fixed path based calls (such as cifs lookup) to handle path names
247 longer than 530 (now can handle PATH_MAX). Fix pass through authentication
248 from Samba server to DC (Samba required dummy LM password).
252 Turn off DNOTIFY (directory change notification support) by default
253 (unless built with the experimental flag) to fix hang with KDE
254 file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
255 waiting on an SMB response) in SendReceive when session dies but
256 reconnects quickly from another task. Add module init parms for
257 minimum number of large and small network buffers in the buffer pools,
258 and for the maximum number of simultaneous requests.
262 Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
263 and other POSIX CIFS compliant servers. Fix error mapping for getfacl
264 to EOPNOTSUPP when server does not support posix acls on the wire. Fix
265 improperly zeroed buffer in CIFS Unix extensions set times call.
269 Fix internationalization problem in cifs readdir with filenames that map to
270 longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
271 for readdir to netapp servers. Fix search rewind (seek into readdir to return
272 non-consecutive entries). Do not do readdir when server negotiates
273 buffer size to small to fit filename. Add support for reading POSIX ACLs from
274 the server (add also acl and noacl mount options).
278 Optionally allow using server side inode numbers, rather than client generated
279 ones by specifying mount option "serverino" - this is required for some apps
280 to work which double check hardlinked files and have persistent inode numbers.
284 Multiple bigendian fixes. On little endian systems (for reconnect after
285 network failure) fix tcp session reconnect code so we do not try first
286 to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
287 as directories rather than symlinks because we can do follow link on them.
291 Add config option to enable XATTR (extended attribute) support, mapping
292 xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
293 minor fixes pointed out by the Stanford SWAT checker (mostly missing
294 or out of order NULL pointer checks in little used error paths).
298 Add new mount parm to control whether mode check (generic_permission) is done
299 on the client. If Unix extensions are enabled and the uids on the client
300 and server do not match, client permission checks are meaningless on
301 server uids that do not exist on the client (this does not affect the
302 normal ACL check which occurs on the server). Fix default uid
303 on mknod to match create and mkdir. Add optional mount parm to allow
304 override of the default uid behavior (in which the server sets the uid
305 and gid of newly created files). Normally for network filesystem mounts
306 user want the server to set the uid/gid on newly created files (rather than
307 using uid of the client processes you would in a local filesystem).
311 Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
312 info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
313 (in build_wildcard_path_from_dentry). Fix mknod to pass type field
314 (block/char/fifo) properly. Remove spurious mount warning log entry when
315 credentials passed as mount argument. Set major/minor device number in
316 inode for block and char devices when unix extensions enabled.
320 Fix /proc/fs/cifs/Stats and DebugData display to handle larger
321 amounts of return data. Properly limit requests to MAX_REQ (50
322 is the usual maximum active multiplex SMB/CIFS requests per server).
323 Do not kill cifsd (and thus hurt the other SMB session) when more than one
324 session to the same server (but with different userids) exists and one
325 of the two user's smb sessions is being removed while leaving the other.
326 Do not loop reconnecting in cifsd demultiplex thread when admin
327 kills the thread without going through unmount.
331 Do not rename hardlinked files (since that should be a noop). Flush
332 cached write behind data when reopening a file after session abend,
333 except when already in write. Grab per socket sem during reconnect
334 to avoid oops in sendmsg if overlapping with reconnect. Do not
335 reset cached inode file size on readdir for files open for write on
341 Update number of blocks in file so du command is happier (in Linux a fake
342 blocksize of 512 is required for calculating number of blocks in inode).
343 Fix prepare write of partial pages to read in data from server if possible.
344 Fix race on tcpStatus field between unmount and reconnection code, causing
345 cifsd process sometimes to hang around forever. Improve out of memory
346 checks in cifs_filldir
350 Fix incorrect file size in file handle based setattr on big endian hardware.
351 Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
352 and closing file structs in writepage/partialpagewrite. Add statistics
353 for each mounted share (new menuconfig option). Fix endianness problem in
354 volume information displayed in /proc/fs/cifs/DebugData (only affects
355 affects big endian architectures). Prevent renames while constructing
356 path names for open, mkdir and rmdir.
360 Change to mempools for alloc smb request buffers and multiplex structs
361 to better handle low memory problems (and potential deadlocks).
365 Fix incomplete listings of large directories on Samba servers when Unix
366 extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
367 rename deadlock when writing out dirty pages at same time.
371 Fix open of files in which O_CREATE can cause the mode to change in
372 some cases. Fix case in which retry of write overlaps file close.
373 Fix PPC64 build error. Reduce excessive stack usage in smb password
374 hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
378 Fixes for large file copy, signal handling, socket retry, buffer
379 allocation and low memory situations.
383 Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
384 also now allowing support for specifying client netbiosname. NT4 support added.
388 Fix reconnection (and certain failed mounts) to properly wake up the
389 blocked users thread so it does not seem hung (in some cases was blocked
390 until the cifs receive timeout expired). Fix spurious error logging
391 to kernel log when application with open network files killed.
395 Fix /proc/fs module unload warning message (that could be logged
396 to the kernel log). Fix intermittent failure in connectathon
397 test7 (hardlink count not immediately refreshed in case in which
398 inode metadata can be incorrectly kept cached when time near zero)
402 Allow file_mode and dir_mode (specified at mount time) to be enforced
403 locally (the server already enforced its own ACLs too) for servers
404 that do not report the correct mode (do not support the
405 CIFS Unix Extensions).
409 Fix some small memory leaks in some unmount error paths. Fix major leak
410 of cache pages in readpages causing multiple read oriented stress
411 testcases (including fsx, and even large file copy) to fail over time.
415 Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
416 This allows files that differ only in case and improves performance of file
417 creation and file open to such servers. Fix semaphore conflict which causes
418 slow delete of open file to Samba (which unfortunately can cause an oplock
419 break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
423 fixes to cifs_readpages for fsx test case
427 Fix caching data integrity bug when extending file size especially when no
428 oplock on file. Fix spurious logging of valid already parsed mount options
429 that are parsed outside of the cifs vfs such as nosuid.
434 Connect to server when port number override not specified, and tcp port
435 unitialized. Reset search to restart at correct file when kernel routine
436 filldir returns error during large directory searches (readdir).
440 Fix caching problem when files opened by multiple clients in which
441 page cache could contain stale data, and write through did
442 not occur often enough while file was still open when read ahead
443 (read oplock) not allowed. Treat "sep=" when first mount option
444 as an override of comma as the default separator between mount
449 Allow passwords longer than 16 bytes. Allow null password string.
453 Gracefully clean up failed mounts when attempting to mount to servers such as
454 Windows 98 that terminate tcp sessions during protocol negotiation. Handle
455 embedded commas in mount parsing of passwords.
459 Invalidate local inode cached pages on oplock break and when last file
460 instance is closed so that the client does not continue using stale local
461 copy rather than later modified server copy of file. Do not reconnect
462 when server drops the tcp session prematurely before negotiate
463 protocol response. Fix oops in reopen_file when dentry freed. Allow
464 the support for CIFS Unix Extensions to be disabled via proc interface.
468 Fix hang in commit_write during reconnection of open files under heavy load.
469 Fix unload_nls oops in a mount failure path. Serialize writes to same socket
470 which also fixes any possible races when cifs signatures are enabled in SMBs
471 being sent out of signature sequence number order.
475 Fix byte range locking bug (endian problem) causing bad offset and
480 Fix oops (in send_sig) caused by CIFS unmount code trying to
481 wake up the demultiplex thread after it had exited. Do not log
482 error on harmless oplock release of closed handle.
486 Fix unsafe global variable usage and password hash failure on gcc 3.3.1
487 Fix problem reconnecting secondary mounts to same server after session
488 failure. Fix invalid dentry - race in mkdir when directory gets created
489 by another client between the lookup and mkdir.
493 Fix to list processing in reopen_files. Fix reconnection when server hung
494 but tcpip session still alive. Set proper timeout on socket read.
498 Add missing mount options including iocharset. SMP fixes in write and open.
499 Fix errors in reconnecting after TCP session failure. Fix module unloading
500 of default nls codepage
504 Active smb transactions should never go negative (fix double FreeXid). Fix
505 list processing in file routines. Check return code on kmalloc in open.
506 Fix spinlock usage for SMP.
510 Fix oops in reopen_files when invalid dentry. drop dentry on server rename
511 and on revalidate errors. Fix cases where pid is now tgid. Fix return code
512 on create hard link when server does not support them.
516 Fix scheduling while atomic error in getting inode info on newly created file.
517 Fix truncate of existing files opened with O_CREAT but not O_TRUNC set.
521 Fix oops on write to dead tcp session. Remove error log write for case when file open
522 O_CREAT but not O_EXCL
526 Fix non-POSIX behavior on rename of open file and delete of open file by taking
527 advantage of trans2 SetFileInfo rename facility if available on target server.
528 Retry on ENOSPC and EAGAIN socket errors.
532 Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix
533 allocation size miscalculation. After oplock token lost do not read through
538 Fix oops on empty file readahead. Fix for file size handling for locally cached files.
542 Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files
543 during auto reconnection to server after server recovered from failure.
547 Finish support for Linux 2.5 open/create changes, which removes the
548 redundant NTCreate/QPathInfo/close that was sent during file create.
549 Enable oplock by default. Enable packet signing by default (needed to
550 access many recent Windows servers)
554 Fix oops when mounting to long server names caused by inverted parms to kmalloc.
555 Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
556 we will choose a cifs user session (smb uid) that better matches the local
557 uid if a) the mount uid does not match the current uid and b) we have another
558 session to the same server (ip address) for a different mount which
559 matches the current local uid.
563 Add support for mknod of block or character devices. Fix oplock
564 code (distributed caching) to properly send response to oplock
569 Finish up CIFS packet digital signing for the default
570 NTLM security case. This should help Windows 2003
571 network interoperability since it is common for
572 packet signing to be required now. Fix statfs (stat -f)
573 which recently started returning errors due to
574 invalid value (-1 instead of 0) being set in the
575 struct kstatfs f_ffiles field.
579 Fix oops on stopping oplock thread when removing cifs when
584 Fix mount options for ro (readonly), uid, gid and file and directory mode.
588 Fix errors displayed on failed mounts to be more understandable.
589 Fixed various incorrect or misleading smb to posix error code mappings.
593 Fix display of NTFS DFS junctions to display as symlinks.
594 They are the network equivalent. Fix oops in
595 cifs_partialpagewrite caused by missing spinlock protection
596 of openfile linked list. Allow writebehind caching errors to
597 be returned to the application at file close.
601 Clean up options displayed in /proc/mounts by show_options to
602 be more consistent with other filesystems.
606 Fix delete of readonly file to Windows servers. Reflect
607 presence or absence of read only dos attribute in mode
608 bits for servers that do not support CIFS Unix extensions.
609 Fix shortened results on readdir of large directories to
610 servers supporting CIFS Unix extensions (caused by
611 incorrect resume key).
615 Fix truncate bug (set file size) that could cause hangs e.g. running fsx
619 unload nls if mount fails.
623 Add resume key support to search (readdir) code to workaround
624 Windows bug. Add /proc/fs/cifs/LookupCacheEnable which
625 allows disabling caching of attribute information for
630 Add more oplock handling (distributed caching code). Remove
631 dead code. Remove excessive stack space utilization from
636 Fix oops in get dfs referral (triggered when null path sent in to
637 mount). Add support for overriding rsize at mount time.
641 Fix buffer overrun in readdir which caused intermittent kernel oopses.
642 Fix writepage code to release kmap on write data. Allow "-ip=" new
643 mount option to be passed in on parameter distinct from the first part
644 (server name portion of) the UNC name. Allow override of the
645 tcp port of the target server via new mount option "-port="
649 Fix search handle leak on rewind. Fix setuid and gid so that they are
650 reflected in the local inode immediately. Cleanup of whitespace
651 to make 2.4 and 2.5 versions more consistent.
656 Fix signal sending so that captive thread (cifsd) exits on umount
657 (which was causing the warning in kmem_cache_free of the request buffers
658 at rmmod time). This had broken as a sideeffect of the recent global
659 kernel change to daemonize. Fix memory leak in readdir code which
660 showed up in "ls -R" (and applications that did search rewinding).
664 Reconnect tids and fids after session reconnection (still do not
665 reconnect byte range locks though). Fix problem caching
666 lookup information for directory inodes, improving performance,
667 especially in deep directory trees. Fix various build warnings.
671 Finish fixes to commit write for caching/readahead consistency. fsx
672 now works to Samba servers. Fix oops caused when readahead
673 was interrupted by a signal.
677 Fix data corruption (in partial page after truncate) that caused fsx to
678 fail to Windows servers. Cleaned up some extraneous error logging in
679 common error paths. Add generic sendfile support.
683 Fix memory leak in AllocMidQEntry.
684 Finish reconnection logic, so connection with server can be dropped
685 (or server rebooted) and the cifs client will reconnect.
689 Fix temporary socket leak when bad userid or password specified
690 (or other SMBSessSetup failure). Increase maximum buffer size to slightly
691 over 16K to allow negotiation of up to Samba and Windows server default read
692 sizes. Add support for readpages
696 Fix oops when username not passed in on mount. Extensive fixes and improvements
697 to error logging (strip redundant newlines, change debug macros to ensure newline
698 passed in and to be more consistent). Fix writepage wrong file handle problem,
699 a readonly file handle could be incorrectly used to attempt to write out
700 file updates through the page cache to multiply open files. This could cause
701 the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
702 shares to the same Windows server when using different usernames
703 (doing this to Samba servers worked but Windows was rejecting it) - now it is
704 possible to use different userids when connecting to the same server from a
705 Linux client. Fix oops when treeDisconnect called during unmount on
706 previously freed socket.
710 Fix oops in readpages caused by not setting address space operations in inode in
715 Includes support for deleting of open files and renaming over existing files (per POSIX
716 requirement). Add readlink support for Windows junction points (directory symlinks).
720 Changed read and write to go through pagecache. Added additional address space operations.
721 Memory mapped operations now working.
725 Added writepage code for additional memory mapping support. Fixed leak in xids causing
726 the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
727 every stat call. Additional formatting cleanup.
731 Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
735 Fixes from Zwane Mwaikambo for adding missing return code checking in a few places.
736 Also included a modified version of his fix to protect global list manipulation of
737 the smb session and tree connection and mid related global variables.
741 Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
742 changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
743 buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
747 More stylistic updates to better match kernel style. Add additional statistics
748 for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
749 and CIFS Packet Signing enablement.
753 Replace call to sleep_on with safer wait_on_event.
754 Make stylistic changes to better match kernel style recommendations.
755 Remove most typedef usage (except for the PDUs themselves).
759 Update mount so the -unc mount option is no longer required (the ip address can be specified
760 in a UNC style device name. Implementation of readpage/writepage started.
764 Fix intermittent problem with incorrect smb header checking on badly
765 fragmented tcp responses
769 Fixes to setting of allocation size and file size.
773 Various 2.5.38 fixes. Now works on 2.5.38
777 Prepare for 2.5 kernel merge. Remove ifdefs.
781 Socket buffer management fixes. Fix dual free.
785 Various big endian fixes for hardlinks and symlinks and also for dfs.
789 Various big endian fixes for servers with Unix extensions such as Samba
793 Various FindNext fixes for incorrect filenames on large directory searches on big endian
794 clients. basic posix file i/o tests now work on big endian machines, not just le
798 SessionSetup and NegotiateProtocol now work from Big Endian machines.
799 Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older
800 versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7).
804 Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
805 files now return the correct number of links on fstat as they are repeatedly linked and unlinked.
809 Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
810 session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
811 Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
812 (which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).
816 Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
817 it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
821 Rewrote much of connection and mount/unmount logic to handle bugs with
822 multiple uses to same share, multiple users to same server etc.
826 Fixed major problem with dentry corruption (missing call to dput)
830 Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
831 Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
832 although corresponding function not fully implemented in the vfs yet
836 Fixed dentry caching bug, misc. cleanup
840 Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
841 on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
842 Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
846 Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
847 and tested against Samba 2.2.5
852 1) Fixed lockrange to be correct (it was one byte too short)
854 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
855 show range as locked when there is a conflict with an existing lock.
857 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
858 in most cases. Eventually will offer optional ability to query server for the correct perms.
860 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
861 but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
864 4) Fixed error logging of valid mount options
866 5) Removed logging of password field.
868 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
869 and cleaned them up and made them more consistent with other cifs functions.
871 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
872 (with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
873 nor is the symlink support using the Unix extensions
875 8) Started adding the readlink and follow_link code
