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