3 Rewritten sessionsetup support, including support for legacy SMB
4 session setup needed for OS/2 and older servers such as Windows 95 and 98.
5 Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
6 so we can do search (ls etc.) to OS/2. Do not send NTCreateX
7 or recent levels of FindFirst unless server says it supports NT SMBs
8 (instead use legacy equivalents from LANMAN dialect). Fix to allow
9 NTLMv2 authentication support (now can use stronger password hashing
10 on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
11 Allow override of global cifs security flags on mount via "sec=" option(s).
15 POSIX locking to servers which support CIFS POSIX Extensions
16 (disabled by default controlled by proc/fs/cifs/Experimental).
17 Handle conversion of long share names (especially Asian languages)
18 to Unicode during mount. Fix memory leak in sess struct on reconnect.
19 Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
20 cifs open which helps rare case when setpathinfo fails or server does
25 Fix slow oplock break when mounted to different servers at the same time and
26 the tids match and we try to find matching fid on wrong server. Fix read
27 looping when signing required by server (2.6.16 kernel only). Fix readdir
28 vs. rename race which could cause each to hang. Return . and .. even
29 if server does not. Allow searches to skip first three entries and
30 begin at any location. Fix oops in find_writeable_file.
34 Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
35 configure stronger authentication. Fix sfu symlinks so they can
36 be followed (not just recognized). Fix wraparound of bcc on
37 read responses when buffer size over 64K and also fix wrap of
38 max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
39 cifs_user_read and cifs_readpages (when EAGAIN on send of smb
40 on socket is returned over and over). Add POSIX (advisory) byte range
41 locking support (requires server with newest CIFS UNIX Extensions
42 to the protocol implemented). Slow down negprot slightly in port 139
43 RFC1001 case to give session_init time on buggy servers.
47 Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
48 of readpages by eliminating one extra memcpy. Allow update of file size
49 from remote server even if file is open for write as long as mount is
50 directio. Recognize share mode security and send NTLM encrypted password
51 on tree connect if share mode negotiated.
55 Defer close of a file handle slightly if pending writes depend on that handle
56 (this reduces the EBADF bad file handle errors that can be logged under heavy
57 stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
58 Fix SFU style symlinks and mknod needed for servers which do not support the
59 CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
60 dentries so files that the client sees as deleted but that later get created
61 on the server will be recognized. Add client side permission check on setattr.
62 Timeout stuck requests better (where server has never responded or sent corrupt
67 Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
68 to be smaller at first (but increasing) so large write performance performance
69 over GigE is better. Do not hang thread on illegal byte range lock response
70 from Windows (Windows can send an RFC1001 size which does not match smb size) by
71 allowing an SMBs TCP length to be up to a few bytes longer than it should be.
72 wsize and rsize can now be larger than negotiated buffer size if server
73 supports large readx/writex, even when directio mount flag not specified.
74 Write size will in many cases now be 16K instead of 4K which greatly helps
75 file copy performance on lightly loaded networks. Fix oops in dnotify
76 when experimental config flag enabled. Make cifsFYI more granular.
80 Fix readdir caching when unlink removes file in current search buffer,
81 and this is followed by a rewind search to just before the deleted entry.
82 Do not attempt to set ctime unless atime and/or mtime change requested
83 (most servers throw it away anyway). Fix length check of received smbs
84 to be more accurate. Fix big endian problem with mapchars mount option,
85 and with a field returned by statfs.
89 Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
90 For these older servers, add option for passing netbios name of server in
91 on mount (servernetbiosname). Add suspend support for power management, to
92 avoid cifsd thread preventing software suspend from working.
93 Add mount option for disabling the default behavior of sending byte range lock
94 requests to the server (necessary for certain applications which break with
95 mandatory lock behavior such as Evolution), and also mount option for
96 requesting case insensitive matching for path based requests (requesting
97 case sensitive is the default).
101 Add writepage performance improvements. Fix path name conversions
102 for long filenames on mounts which were done with "mapchars" mount option
103 specified. Ensure multiplex ids do not collide. Fix case in which
104 rmmod can oops if done soon after last unmount. Fix truncated
105 search (readdir) output when resume filename was a long filename.
106 Fix filename conversion when mapchars mount option was specified and
107 filename was a long filename.
111 Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
112 Do not oops if root user kills cifs oplock kernel thread or
113 kills the cifsd thread (NB: killing the cifs kernel threads is not
114 recommended, unmount and rmmod cifs will kill them when they are
115 no longer needed). Fix readdir to ASCII servers (ie older servers
116 which do not support Unicode) and also require asterisk.
117 Fix out of memory case in which data could be written one page
118 off in the page cache.
122 Fix caching problem, in which readdir of directory containing a file
123 which was cached could cause the file's time stamp to be updated
124 without invalidating the readahead data (so we could get stale
125 file data on the client for that file even as the server copy changed).
126 Cleanup response processing so cifsd can not loop when abnormally
132 Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
133 transact response for an SMB request and search entry split across two frames.
134 Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
135 as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
136 unless server explicitly claims to support them in CIFS Unix extensions
137 POSIX ACL capability bit. Fix packet signing when multiuser mounting with
138 different users from the same client to the same server. Fix oops in
139 cifs_close. Add mount option for remapping reserved characters in
140 filenames (also allow recognizing files with created by SFU which have any
141 of these seven reserved characters, except backslash, to be recognized).
142 Fix invalid transact2 message (we were sometimes trying to interpret
143 oplock breaks as SMB responses). Add ioctl for checking that the
144 current uid matches the uid of the mounter (needed by umount.cifs).
145 Reduce the number of large buffer allocations in cifs response processing
146 (significantly reduces memory pressure under heavy stress with multiple
147 processes accessing the same server at the same time).
151 Fix updates of DOS attributes and time fields so that files on NT4 servers
152 do not get marked delete on close. Display sizes of cifs buffer pools in
153 cifs stats. Fix oops in unmount when cifsd thread being killed by
154 shutdown. Add generic readv/writev and aio support. Report inode numbers
155 consistently in readdir and lookup (when serverino mount option is
156 specified use the inode number that the server reports - for both lookup
157 and readdir, otherwise by default the locally generated inode number is used
158 for inodes created in either path since servers are not always able to
159 provide unique inode numbers when exporting multiple volumes from under one
164 Allow new nouser_xattr mount parm to disable xattr support for user namespace.
165 Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
166 (mostly affects NT4 servers) by retry with handle based network operation.
167 Add new POSIX Query FS Info for returning statfs info more accurately.
168 Handle passwords with multiple commas in them.
172 Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
173 Fix capabilities flags for large readx so as to allow reads larger than 64K.
177 Add module init parm for large SMB buffer size (to allow it to be changed
178 from its default of 16K) which is especially useful for large file copy
179 when mounting with the directio mount option. Fix oops after
180 returning from mount when experimental ExtendedSecurity enabled and
181 SpnegoNegotiated returning invalid error. Fix case to retry better when
182 peek returns from 1 to 3 bytes on socket which should have more data.
183 Fixed path based calls (such as cifs lookup) to handle path names
184 longer than 530 (now can handle PATH_MAX). Fix pass through authentication
185 from Samba server to DC (Samba required dummy LM password).
189 Turn off DNOTIFY (directory change notification support) by default
190 (unless built with the experimental flag) to fix hang with KDE
191 file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
192 waiting on an SMB response) in SendReceive when session dies but
193 reconnects quickly from another task. Add module init parms for
194 minimum number of large and small network buffers in the buffer pools,
195 and for the maximum number of simultaneous requests.
199 Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
200 and other POSIX CIFS compliant servers. Fix error mapping for getfacl
201 to EOPNOTSUPP when server does not support posix acls on the wire. Fix
202 improperly zeroed buffer in CIFS Unix extensions set times call.
206 Fix internationalization problem in cifs readdir with filenames that map to
207 longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
208 for readdir to netapp servers. Fix search rewind (seek into readdir to return
209 non-consecutive entries). Do not do readdir when server negotiates
210 buffer size to small to fit filename. Add support for reading POSIX ACLs from
211 the server (add also acl and noacl mount options).
215 Optionally allow using server side inode numbers, rather than client generated
216 ones by specifying mount option "serverino" - this is required for some apps
217 to work which double check hardlinked files and have persistent inode numbers.
221 Multiple bigendian fixes. On little endian systems (for reconnect after
222 network failure) fix tcp session reconnect code so we do not try first
223 to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
224 as directories rather than symlinks because we can do follow link on them.
228 Add config option to enable XATTR (extended attribute) support, mapping
229 xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
230 minor fixes pointed out by the Stanford SWAT checker (mostly missing
231 or out of order NULL pointer checks in little used error paths).
235 Add new mount parm to control whether mode check (generic_permission) is done
236 on the client. If Unix extensions are enabled and the uids on the client
237 and server do not match, client permission checks are meaningless on
238 server uids that do not exist on the client (this does not affect the
239 normal ACL check which occurs on the server). Fix default uid
240 on mknod to match create and mkdir. Add optional mount parm to allow
241 override of the default uid behavior (in which the server sets the uid
242 and gid of newly created files). Normally for network filesystem mounts
243 user want the server to set the uid/gid on newly created files (rather than
244 using uid of the client processes you would in a local filesystem).
248 Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
249 info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
250 (in build_wildcard_path_from_dentry). Fix mknod to pass type field
251 (block/char/fifo) properly. Remove spurious mount warning log entry when
252 credentials passed as mount argument. Set major/minor device number in
253 inode for block and char devices when unix extensions enabled.
257 Fix /proc/fs/cifs/Stats and DebugData display to handle larger
258 amounts of return data. Properly limit requests to MAX_REQ (50
259 is the usual maximum active multiplex SMB/CIFS requests per server).
260 Do not kill cifsd (and thus hurt the other SMB session) when more than one
261 session to the same server (but with different userids) exists and one
262 of the two user's smb sessions is being removed while leaving the other.
263 Do not loop reconnecting in cifsd demultiplex thread when admin
264 kills the thread without going through unmount.
268 Do not rename hardlinked files (since that should be a noop). Flush
269 cached write behind data when reopening a file after session abend,
270 except when already in write. Grab per socket sem during reconnect
271 to avoid oops in sendmsg if overlapping with reconnect. Do not
272 reset cached inode file size on readdir for files open for write on
278 Update number of blocks in file so du command is happier (in Linux a fake
279 blocksize of 512 is required for calculating number of blocks in inode).
280 Fix prepare write of partial pages to read in data from server if possible.
281 Fix race on tcpStatus field between unmount and reconnection code, causing
282 cifsd process sometimes to hang around forever. Improve out of memory
283 checks in cifs_filldir
287 Fix incorrect file size in file handle based setattr on big endian hardware.
288 Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
289 and closing file structs in writepage/partialpagewrite. Add statistics
290 for each mounted share (new menuconfig option). Fix endianness problem in
291 volume information displayed in /proc/fs/cifs/DebugData (only affects
292 affects big endian architectures). Prevent renames while constructing
293 path names for open, mkdir and rmdir.
297 Change to mempools for alloc smb request buffers and multiplex structs
298 to better handle low memory problems (and potential deadlocks).
302 Fix incomplete listings of large directories on Samba servers when Unix
303 extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
304 rename deadlock when writing out dirty pages at same time.
308 Fix open of files in which O_CREATE can cause the mode to change in
309 some cases. Fix case in which retry of write overlaps file close.
310 Fix PPC64 build error. Reduce excessive stack usage in smb password
311 hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
315 Fixes for large file copy, signal handling, socket retry, buffer
316 allocation and low memory situations.
320 Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
321 also now allowing support for specifying client netbiosname. NT4 support added.
325 Fix reconnection (and certain failed mounts) to properly wake up the
326 blocked users thread so it does not seem hung (in some cases was blocked
327 until the cifs receive timeout expired). Fix spurious error logging
328 to kernel log when application with open network files killed.
332 Fix /proc/fs module unload warning message (that could be logged
333 to the kernel log). Fix intermittent failure in connectathon
334 test7 (hardlink count not immediately refreshed in case in which
335 inode metadata can be incorrectly kept cached when time near zero)
339 Allow file_mode and dir_mode (specified at mount time) to be enforced
340 locally (the server already enforced its own ACLs too) for servers
341 that do not report the correct mode (do not support the
342 CIFS Unix Extensions).
346 Fix some small memory leaks in some unmount error paths. Fix major leak
347 of cache pages in readpages causing multiple read oriented stress
348 testcases (including fsx, and even large file copy) to fail over time.
352 Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
353 This allows files that differ only in case and improves performance of file
354 creation and file open to such servers. Fix semaphore conflict which causes
355 slow delete of open file to Samba (which unfortunately can cause an oplock
356 break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
360 fixes to cifs_readpages for fsx test case
364 Fix caching data integrity bug when extending file size especially when no
365 oplock on file. Fix spurious logging of valid already parsed mount options
366 that are parsed outside of the cifs vfs such as nosuid.
371 Connect to server when port number override not specified, and tcp port
372 unitialized. Reset search to restart at correct file when kernel routine
373 filldir returns error during large directory searches (readdir).
377 Fix caching problem when files opened by multiple clients in which
378 page cache could contain stale data, and write through did
379 not occur often enough while file was still open when read ahead
380 (read oplock) not allowed. Treat "sep=" when first mount option
381 as an override of comma as the default separator between mount
386 Allow passwords longer than 16 bytes. Allow null password string.
390 Gracefully clean up failed mounts when attempting to mount to servers such as
391 Windows 98 that terminate tcp sessions during protocol negotiation. Handle
392 embedded commas in mount parsing of passwords.
396 Invalidate local inode cached pages on oplock break and when last file
397 instance is closed so that the client does not continue using stale local
398 copy rather than later modified server copy of file. Do not reconnect
399 when server drops the tcp session prematurely before negotiate
400 protocol response. Fix oops in reopen_file when dentry freed. Allow
401 the support for CIFS Unix Extensions to be disabled via proc interface.
405 Fix hang in commit_write during reconnection of open files under heavy load.
406 Fix unload_nls oops in a mount failure path. Serialize writes to same socket
407 which also fixes any possible races when cifs signatures are enabled in SMBs
408 being sent out of signature sequence number order.
412 Fix byte range locking bug (endian problem) causing bad offset and
417 Fix oops (in send_sig) caused by CIFS unmount code trying to
418 wake up the demultiplex thread after it had exited. Do not log
419 error on harmless oplock release of closed handle.
423 Fix unsafe global variable usage and password hash failure on gcc 3.3.1
424 Fix problem reconnecting secondary mounts to same server after session
425 failure. Fix invalid dentry - race in mkdir when directory gets created
426 by another client between the lookup and mkdir.
430 Fix to list processing in reopen_files. Fix reconnection when server hung
431 but tcpip session still alive. Set proper timeout on socket read.
435 Add missing mount options including iocharset. SMP fixes in write and open.
436 Fix errors in reconnecting after TCP session failure. Fix module unloading
437 of default nls codepage
441 Active smb transactions should never go negative (fix double FreeXid). Fix
442 list processing in file routines. Check return code on kmalloc in open.
443 Fix spinlock usage for SMP.
447 Fix oops in reopen_files when invalid dentry. drop dentry on server rename
448 and on revalidate errors. Fix cases where pid is now tgid. Fix return code
449 on create hard link when server does not support them.
453 Fix scheduling while atomic error in getting inode info on newly created file.
454 Fix truncate of existing files opened with O_CREAT but not O_TRUNC set.
458 Fix oops on write to dead tcp session. Remove error log write for case when file open
459 O_CREAT but not O_EXCL
463 Fix non-POSIX behavior on rename of open file and delete of open file by taking
464 advantage of trans2 SetFileInfo rename facility if available on target server.
465 Retry on ENOSPC and EAGAIN socket errors.
469 Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix
470 allocation size miscalculation. After oplock token lost do not read through
475 Fix oops on empty file readahead. Fix for file size handling for locally cached files.
479 Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files
480 during auto reconnection to server after server recovered from failure.
484 Finish support for Linux 2.5 open/create changes, which removes the
485 redundant NTCreate/QPathInfo/close that was sent during file create.
486 Enable oplock by default. Enable packet signing by default (needed to
487 access many recent Windows servers)
491 Fix oops when mounting to long server names caused by inverted parms to kmalloc.
492 Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
493 we will choose a cifs user session (smb uid) that better matches the local
494 uid if a) the mount uid does not match the current uid and b) we have another
495 session to the same server (ip address) for a different mount which
496 matches the current local uid.
500 Add support for mknod of block or character devices. Fix oplock
501 code (distributed caching) to properly send response to oplock
506 Finish up CIFS packet digital signing for the default
507 NTLM security case. This should help Windows 2003
508 network interoperability since it is common for
509 packet signing to be required now. Fix statfs (stat -f)
510 which recently started returning errors due to
511 invalid value (-1 instead of 0) being set in the
512 struct kstatfs f_ffiles field.
516 Fix oops on stopping oplock thread when removing cifs when
521 Fix mount options for ro (readonly), uid, gid and file and directory mode.
525 Fix errors displayed on failed mounts to be more understandable.
526 Fixed various incorrect or misleading smb to posix error code mappings.
530 Fix display of NTFS DFS junctions to display as symlinks.
531 They are the network equivalent. Fix oops in
532 cifs_partialpagewrite caused by missing spinlock protection
533 of openfile linked list. Allow writebehind caching errors to
534 be returned to the application at file close.
538 Clean up options displayed in /proc/mounts by show_options to
539 be more consistent with other filesystems.
543 Fix delete of readonly file to Windows servers. Reflect
544 presence or absence of read only dos attribute in mode
545 bits for servers that do not support CIFS Unix extensions.
546 Fix shortened results on readdir of large directories to
547 servers supporting CIFS Unix extensions (caused by
548 incorrect resume key).
552 Fix truncate bug (set file size) that could cause hangs e.g. running fsx
556 unload nls if mount fails.
560 Add resume key support to search (readdir) code to workaround
561 Windows bug. Add /proc/fs/cifs/LookupCacheEnable which
562 allows disabling caching of attribute information for
567 Add more oplock handling (distributed caching code). Remove
568 dead code. Remove excessive stack space utilization from
573 Fix oops in get dfs referral (triggered when null path sent in to
574 mount). Add support for overriding rsize at mount time.
578 Fix buffer overrun in readdir which caused intermittent kernel oopses.
579 Fix writepage code to release kmap on write data. Allow "-ip=" new
580 mount option to be passed in on parameter distinct from the first part
581 (server name portion of) the UNC name. Allow override of the
582 tcp port of the target server via new mount option "-port="
586 Fix search handle leak on rewind. Fix setuid and gid so that they are
587 reflected in the local inode immediately. Cleanup of whitespace
588 to make 2.4 and 2.5 versions more consistent.
593 Fix signal sending so that captive thread (cifsd) exits on umount
594 (which was causing the warning in kmem_cache_free of the request buffers
595 at rmmod time). This had broken as a sideeffect of the recent global
596 kernel change to daemonize. Fix memory leak in readdir code which
597 showed up in "ls -R" (and applications that did search rewinding).
601 Reconnect tids and fids after session reconnection (still do not
602 reconnect byte range locks though). Fix problem caching
603 lookup information for directory inodes, improving performance,
604 especially in deep directory trees. Fix various build warnings.
608 Finish fixes to commit write for caching/readahead consistency. fsx
609 now works to Samba servers. Fix oops caused when readahead
610 was interrupted by a signal.
614 Fix data corruption (in partial page after truncate) that caused fsx to
615 fail to Windows servers. Cleaned up some extraneous error logging in
616 common error paths. Add generic sendfile support.
620 Fix memory leak in AllocMidQEntry.
621 Finish reconnection logic, so connection with server can be dropped
622 (or server rebooted) and the cifs client will reconnect.
626 Fix temporary socket leak when bad userid or password specified
627 (or other SMBSessSetup failure). Increase maximum buffer size to slightly
628 over 16K to allow negotiation of up to Samba and Windows server default read
629 sizes. Add support for readpages
633 Fix oops when username not passed in on mount. Extensive fixes and improvements
634 to error logging (strip redundant newlines, change debug macros to ensure newline
635 passed in and to be more consistent). Fix writepage wrong file handle problem,
636 a readonly file handle could be incorrectly used to attempt to write out
637 file updates through the page cache to multiply open files. This could cause
638 the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
639 shares to the same Windows server when using different usernames
640 (doing this to Samba servers worked but Windows was rejecting it) - now it is
641 possible to use different userids when connecting to the same server from a
642 Linux client. Fix oops when treeDisconnect called during unmount on
643 previously freed socket.
647 Fix oops in readpages caused by not setting address space operations in inode in
652 Includes support for deleting of open files and renaming over existing files (per POSIX
653 requirement). Add readlink support for Windows junction points (directory symlinks).
657 Changed read and write to go through pagecache. Added additional address space operations.
658 Memory mapped operations now working.
662 Added writepage code for additional memory mapping support. Fixed leak in xids causing
663 the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
664 every stat call. Additional formatting cleanup.
668 Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
672 Fixes from Zwane Mwaikambo for adding missing return code checking in a few places.
673 Also included a modified version of his fix to protect global list manipulation of
674 the smb session and tree connection and mid related global variables.
678 Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
679 changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
680 buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
684 More stylistic updates to better match kernel style. Add additional statistics
685 for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
686 and CIFS Packet Signing enablement.
690 Replace call to sleep_on with safer wait_on_event.
691 Make stylistic changes to better match kernel style recommendations.
692 Remove most typedef usage (except for the PDUs themselves).
696 Update mount so the -unc mount option is no longer required (the ip address can be specified
697 in a UNC style device name. Implementation of readpage/writepage started.
701 Fix intermittent problem with incorrect smb header checking on badly
702 fragmented tcp responses
706 Fixes to setting of allocation size and file size.
710 Various 2.5.38 fixes. Now works on 2.5.38
714 Prepare for 2.5 kernel merge. Remove ifdefs.
718 Socket buffer management fixes. Fix dual free.
722 Various big endian fixes for hardlinks and symlinks and also for dfs.
726 Various big endian fixes for servers with Unix extensions such as Samba
730 Various FindNext fixes for incorrect filenames on large directory searches on big endian
731 clients. basic posix file i/o tests now work on big endian machines, not just le
735 SessionSetup and NegotiateProtocol now work from Big Endian machines.
736 Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older
737 versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7).
741 Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
742 files now return the correct number of links on fstat as they are repeatedly linked and unlinked.
746 Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
747 session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
748 Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
749 (which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).
753 Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
754 it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
758 Rewrote much of connection and mount/unmount logic to handle bugs with
759 multiple uses to same share, multiple users to same server etc.
763 Fixed major problem with dentry corruption (missing call to dput)
767 Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
768 Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
769 although corresponding function not fully implemented in the vfs yet
773 Fixed dentry caching bug, misc. cleanup
777 Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
778 on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
779 Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
783 Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
784 and tested against Samba 2.2.5
789 1) Fixed lockrange to be correct (it was one byte too short)
791 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
792 show range as locked when there is a conflict with an existing lock.
794 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
795 in most cases. Eventually will offer optional ability to query server for the correct perms.
797 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
798 but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
801 4) Fixed error logging of valid mount options
803 5) Removed logging of password field.
805 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
806 and cleaned them up and made them more consistent with other cifs functions.
808 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
809 (with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
810 nor is the symlink support using the Unix extensions
812 8) Started adding the readlink and follow_link code
