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