3 Fix oops on second mount to server when null auth is used.
4 Enable experimental Kerberos support. Return writebehind errors on flush
5 and sync so that events like out of disk space get reported properly on
10 Fix memory leak in statfs when mounted to very old servers (e.g.
11 Windows 9x). Add new feature "POSIX open" which allows servers
12 which support the current POSIX Extensions to provide better semantics
13 (e.g. delete for open files opened with posix open). Take into
14 account umask on posix mkdir not just older style mkdir. Add
15 ability to mount to IPC$ share (which allows CIFS named pipes to be
16 opened, read and written as if they were files). When 1st tree
17 connect fails (e.g. due to signing negotiation failure) fix
18 leak that causes cifsd not to stop and rmmod to fail to cleanup
19 cifs_request_buffers pool. Fix problem with POSIX Open/Mkdir on
20 bigendian architectures. Fix possible memory corruption when
21 EAGAIN returned on kern_recvmsg. Return better error if server
22 requires packet signing but client has disabled it. When mounted
23 with cifsacl mount option - mode bits are approximated based
24 on the contents of the ACL of the file or directory. When cifs
25 mount helper is missing convert make sure that UNC name
26 has backslash (not forward slash) between ip address of server
31 Fix NTLMv2 signing. NFS server mounted over cifs works (if cifs mount is
32 done with "serverino" mount option). Add support for POSIX Unlink
33 (helps with certain sharing violation cases when server such as
34 Samba supports newer POSIX CIFS Protocol Extensions). Add "nounix"
35 mount option to allow disabling the CIFS Unix Extensions for just
36 that mount. Fix hang on spinlock in find_writable_file (race when
37 reopening file after session crash). Byte range unlock request to
38 windows server could unlock more bytes (on server copy of file)
39 than intended if start of unlock request is well before start of
40 a previous byte range lock that we issued.
44 IPv6 support. Enable ipv6 addresses to be passed on mount (put the ipv6
45 address after the "ip=" mount option, at least until mount.cifs is fixed to
46 handle DNS host to ipv6 name translation). Accept override of uid or gid
47 on mount even when Unix Extensions are negotiated (it used to be ignored
48 when Unix Extensions were ignored). This allows users to override the
49 default uid and gid for files when they are certain that the uids or
50 gids on the server do not match those of the client. Make "sec=none"
51 mount override username (so that null user connection is attempted)
52 to match what documentation said. Support for very large reads, over 127K,
53 available to some newer servers (such as Samba 3.0.26 and later but
54 note that it also requires setting CIFSMaxBufSize at module install
55 time to a larger value which may hurt performance in some cases).
56 Make sign option force signing (or fail if server does not support it).
60 Fix mtime bouncing around from local idea of last write times to remote time.
61 Fix hang (in i_size_read) when simultaneous size update of same remote file
62 on smp system corrupts sequence number. Do not reread unnecessarily partial page
63 (which we are about to overwrite anyway) when writing out file opened rw.
64 When DOS attribute of file on non-Unix server's file changes on the server side
65 from read-only back to read-write, reflect this change in default file mode
66 (we had been leaving a file's mode read-only until the inode were reloaded).
67 Allow setting of attribute back to ATTR_NORMAL (removing readonly dos attribute
68 when archive dos attribute not set and we are changing mode back to writeable
69 on server which does not support the Unix Extensions). Remove read only dos
70 attribute on chmod when adding any write permission (ie on any of
71 user/group/other (not all of user/group/other ie 0222) when
72 mounted to windows. Add support for POSIX MkDir (slight performance
73 enhancement and eliminates the network race between the mkdir and set
74 path info of the mode).
79 Fix oops in list_del during mount caused by unaligned string.
80 Fix file corruption which could occur on some large file
81 copies caused by writepages page i/o completion bug.
82 Seek to SEEK_END forces check for update of file size for non-cached
83 files. Allow file size to be updated on remote extend of locally open,
84 non-cached file. Fix reconnect to newer Samba servers (or other servers
85 which support the CIFS Unix/POSIX extensions) so that we again tell the
86 server the Unix/POSIX cifs capabilities which we support (SetFSInfo).
87 Add experimental support for new POSIX Open/Mkdir (which returns
88 stat information on the open, and allows setting the mode).
92 Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
93 Allow null user to be specified on mount ("username="). Do not return
94 EINVAL on readdir when filldir fails due to overwritten blocksize
95 (fixes FC problem). Return error in rename 2nd attempt retry (ie report
96 if rename by handle also fails, after rename by path fails, we were
97 not reporting whether the retry worked or not). Fix NTLMv2 to
98 work to Windows servers (mount with option "sec=ntlmv2").
102 Do not time out lockw calls when using posix extensions. Do not
103 time out requests if server still responding reasonably fast
104 on requests on other threads. Improve POSIX locking emulation,
105 (lock cancel now works, and unlock of merged range works even
106 to Windows servers now). Fix oops on mount to lanman servers
107 (win9x, os/2 etc.) when null password. Do not send listxattr
108 (SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
109 problem (instantiate inodes/dentries in right order for readdir).
113 Rewritten sessionsetup support, including support for legacy SMB
114 session setup needed for OS/2 and older servers such as Windows 95 and 98.
115 Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
116 so we can do search (ls etc.) to OS/2. Do not send NTCreateX
117 or recent levels of FindFirst unless server says it supports NT SMBs
118 (instead use legacy equivalents from LANMAN dialect). Fix to allow
119 NTLMv2 authentication support (now can use stronger password hashing
120 on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
121 Allow override of global cifs security flags on mount via "sec=" option(s).
125 POSIX locking to servers which support CIFS POSIX Extensions
126 (disabled by default controlled by proc/fs/cifs/Experimental).
127 Handle conversion of long share names (especially Asian languages)
128 to Unicode during mount. Fix memory leak in sess struct on reconnect.
129 Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
130 cifs open which helps rare case when setpathinfo fails or server does
135 Fix slow oplock break when mounted to different servers at the same time and
136 the tids match and we try to find matching fid on wrong server. Fix read
137 looping when signing required by server (2.6.16 kernel only). Fix readdir
138 vs. rename race which could cause each to hang. Return . and .. even
139 if server does not. Allow searches to skip first three entries and
140 begin at any location. Fix oops in find_writeable_file.
144 Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
145 configure stronger authentication. Fix sfu symlinks so they can
146 be followed (not just recognized). Fix wraparound of bcc on
147 read responses when buffer size over 64K and also fix wrap of
148 max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
149 cifs_user_read and cifs_readpages (when EAGAIN on send of smb
150 on socket is returned over and over). Add POSIX (advisory) byte range
151 locking support (requires server with newest CIFS UNIX Extensions
152 to the protocol implemented). Slow down negprot slightly in port 139
153 RFC1001 case to give session_init time on buggy servers.
157 Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
158 of readpages by eliminating one extra memcpy. Allow update of file size
159 from remote server even if file is open for write as long as mount is
160 directio. Recognize share mode security and send NTLM encrypted password
161 on tree connect if share mode negotiated.
165 Defer close of a file handle slightly if pending writes depend on that handle
166 (this reduces the EBADF bad file handle errors that can be logged under heavy
167 stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
168 Fix SFU style symlinks and mknod needed for servers which do not support the
169 CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
170 dentries so files that the client sees as deleted but that later get created
171 on the server will be recognized. Add client side permission check on setattr.
172 Timeout stuck requests better (where server has never responded or sent corrupt
177 Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
178 to be smaller at first (but increasing) so large write performance performance
179 over GigE is better. Do not hang thread on illegal byte range lock response
180 from Windows (Windows can send an RFC1001 size which does not match smb size) by
181 allowing an SMBs TCP length to be up to a few bytes longer than it should be.
182 wsize and rsize can now be larger than negotiated buffer size if server
183 supports large readx/writex, even when directio mount flag not specified.
184 Write size will in many cases now be 16K instead of 4K which greatly helps
185 file copy performance on lightly loaded networks. Fix oops in dnotify
186 when experimental config flag enabled. Make cifsFYI more granular.
190 Fix readdir caching when unlink removes file in current search buffer,
191 and this is followed by a rewind search to just before the deleted entry.
192 Do not attempt to set ctime unless atime and/or mtime change requested
193 (most servers throw it away anyway). Fix length check of received smbs
194 to be more accurate. Fix big endian problem with mapchars mount option,
195 and with a field returned by statfs.
199 Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
200 For these older servers, add option for passing netbios name of server in
201 on mount (servernetbiosname). Add suspend support for power management, to
202 avoid cifsd thread preventing software suspend from working.
203 Add mount option for disabling the default behavior of sending byte range lock
204 requests to the server (necessary for certain applications which break with
205 mandatory lock behavior such as Evolution), and also mount option for
206 requesting case insensitive matching for path based requests (requesting
207 case sensitive is the default).
211 Add writepage performance improvements. Fix path name conversions
212 for long filenames on mounts which were done with "mapchars" mount option
213 specified. Ensure multiplex ids do not collide. Fix case in which
214 rmmod can oops if done soon after last unmount. Fix truncated
215 search (readdir) output when resume filename was a long filename.
216 Fix filename conversion when mapchars mount option was specified and
217 filename was a long filename.
221 Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
222 Do not oops if root user kills cifs oplock kernel thread or
223 kills the cifsd thread (NB: killing the cifs kernel threads is not
224 recommended, unmount and rmmod cifs will kill them when they are
225 no longer needed). Fix readdir to ASCII servers (ie older servers
226 which do not support Unicode) and also require asterisk.
227 Fix out of memory case in which data could be written one page
228 off in the page cache.
232 Fix caching problem, in which readdir of directory containing a file
233 which was cached could cause the file's time stamp to be updated
234 without invalidating the readahead data (so we could get stale
235 file data on the client for that file even as the server copy changed).
236 Cleanup response processing so cifsd can not loop when abnormally
242 Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
243 transact response for an SMB request and search entry split across two frames.
244 Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
245 as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
246 unless server explicitly claims to support them in CIFS Unix extensions
247 POSIX ACL capability bit. Fix packet signing when multiuser mounting with
248 different users from the same client to the same server. Fix oops in
249 cifs_close. Add mount option for remapping reserved characters in
250 filenames (also allow recognizing files with created by SFU which have any
251 of these seven reserved characters, except backslash, to be recognized).
252 Fix invalid transact2 message (we were sometimes trying to interpret
253 oplock breaks as SMB responses). Add ioctl for checking that the
254 current uid matches the uid of the mounter (needed by umount.cifs).
255 Reduce the number of large buffer allocations in cifs response processing
256 (significantly reduces memory pressure under heavy stress with multiple
257 processes accessing the same server at the same time).
261 Fix updates of DOS attributes and time fields so that files on NT4 servers
262 do not get marked delete on close. Display sizes of cifs buffer pools in
263 cifs stats. Fix oops in unmount when cifsd thread being killed by
264 shutdown. Add generic readv/writev and aio support. Report inode numbers
265 consistently in readdir and lookup (when serverino mount option is
266 specified use the inode number that the server reports - for both lookup
267 and readdir, otherwise by default the locally generated inode number is used
268 for inodes created in either path since servers are not always able to
269 provide unique inode numbers when exporting multiple volumes from under one
274 Allow new nouser_xattr mount parm to disable xattr support for user namespace.
275 Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
276 (mostly affects NT4 servers) by retry with handle based network operation.
277 Add new POSIX Query FS Info for returning statfs info more accurately.
278 Handle passwords with multiple commas in them.
282 Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
283 Fix capabilities flags for large readx so as to allow reads larger than 64K.
287 Add module init parm for large SMB buffer size (to allow it to be changed
288 from its default of 16K) which is especially useful for large file copy
289 when mounting with the directio mount option. Fix oops after
290 returning from mount when experimental ExtendedSecurity enabled and
291 SpnegoNegotiated returning invalid error. Fix case to retry better when
292 peek returns from 1 to 3 bytes on socket which should have more data.
293 Fixed path based calls (such as cifs lookup) to handle path names
294 longer than 530 (now can handle PATH_MAX). Fix pass through authentication
295 from Samba server to DC (Samba required dummy LM password).
299 Turn off DNOTIFY (directory change notification support) by default
300 (unless built with the experimental flag) to fix hang with KDE
301 file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
302 waiting on an SMB response) in SendReceive when session dies but
303 reconnects quickly from another task. Add module init parms for
304 minimum number of large and small network buffers in the buffer pools,
305 and for the maximum number of simultaneous requests.
309 Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
310 and other POSIX CIFS compliant servers. Fix error mapping for getfacl
311 to EOPNOTSUPP when server does not support posix acls on the wire. Fix
312 improperly zeroed buffer in CIFS Unix extensions set times call.
316 Fix internationalization problem in cifs readdir with filenames that map to
317 longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
318 for readdir to netapp servers. Fix search rewind (seek into readdir to return
319 non-consecutive entries). Do not do readdir when server negotiates
320 buffer size to small to fit filename. Add support for reading POSIX ACLs from
321 the server (add also acl and noacl mount options).
325 Optionally allow using server side inode numbers, rather than client generated
326 ones by specifying mount option "serverino" - this is required for some apps
327 to work which double check hardlinked files and have persistent inode numbers.
331 Multiple bigendian fixes. On little endian systems (for reconnect after
332 network failure) fix tcp session reconnect code so we do not try first
333 to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
334 as directories rather than symlinks because we can do follow link on them.
338 Add config option to enable XATTR (extended attribute) support, mapping
339 xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
340 minor fixes pointed out by the Stanford SWAT checker (mostly missing
341 or out of order NULL pointer checks in little used error paths).
345 Add new mount parm to control whether mode check (generic_permission) is done
346 on the client. If Unix extensions are enabled and the uids on the client
347 and server do not match, client permission checks are meaningless on
348 server uids that do not exist on the client (this does not affect the
349 normal ACL check which occurs on the server). Fix default uid
350 on mknod to match create and mkdir. Add optional mount parm to allow
351 override of the default uid behavior (in which the server sets the uid
352 and gid of newly created files). Normally for network filesystem mounts
353 user want the server to set the uid/gid on newly created files (rather than
354 using uid of the client processes you would in a local filesystem).
358 Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
359 info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
360 (in build_wildcard_path_from_dentry). Fix mknod to pass type field
361 (block/char/fifo) properly. Remove spurious mount warning log entry when
362 credentials passed as mount argument. Set major/minor device number in
363 inode for block and char devices when unix extensions enabled.
367 Fix /proc/fs/cifs/Stats and DebugData display to handle larger
368 amounts of return data. Properly limit requests to MAX_REQ (50
369 is the usual maximum active multiplex SMB/CIFS requests per server).
370 Do not kill cifsd (and thus hurt the other SMB session) when more than one
371 session to the same server (but with different userids) exists and one
372 of the two user's smb sessions is being removed while leaving the other.
373 Do not loop reconnecting in cifsd demultiplex thread when admin
374 kills the thread without going through unmount.
378 Do not rename hardlinked files (since that should be a noop). Flush
379 cached write behind data when reopening a file after session abend,
380 except when already in write. Grab per socket sem during reconnect
381 to avoid oops in sendmsg if overlapping with reconnect. Do not
382 reset cached inode file size on readdir for files open for write on
388 Update number of blocks in file so du command is happier (in Linux a fake
389 blocksize of 512 is required for calculating number of blocks in inode).
390 Fix prepare write of partial pages to read in data from server if possible.
391 Fix race on tcpStatus field between unmount and reconnection code, causing
392 cifsd process sometimes to hang around forever. Improve out of memory
393 checks in cifs_filldir
397 Fix incorrect file size in file handle based setattr on big endian hardware.
398 Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
399 and closing file structs in writepage/partialpagewrite. Add statistics
400 for each mounted share (new menuconfig option). Fix endianness problem in
401 volume information displayed in /proc/fs/cifs/DebugData (only affects
402 affects big endian architectures). Prevent renames while constructing
403 path names for open, mkdir and rmdir.
407 Change to mempools for alloc smb request buffers and multiplex structs
408 to better handle low memory problems (and potential deadlocks).
412 Fix incomplete listings of large directories on Samba servers when Unix
413 extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
414 rename deadlock when writing out dirty pages at same time.
418 Fix open of files in which O_CREATE can cause the mode to change in
419 some cases. Fix case in which retry of write overlaps file close.
420 Fix PPC64 build error. Reduce excessive stack usage in smb password
421 hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
425 Fixes for large file copy, signal handling, socket retry, buffer
426 allocation and low memory situations.
430 Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
431 also now allowing support for specifying client netbiosname. NT4 support added.
435 Fix reconnection (and certain failed mounts) to properly wake up the
436 blocked users thread so it does not seem hung (in some cases was blocked
437 until the cifs receive timeout expired). Fix spurious error logging
438 to kernel log when application with open network files killed.
442 Fix /proc/fs module unload warning message (that could be logged
443 to the kernel log). Fix intermittent failure in connectathon
444 test7 (hardlink count not immediately refreshed in case in which
445 inode metadata can be incorrectly kept cached when time near zero)
449 Allow file_mode and dir_mode (specified at mount time) to be enforced
450 locally (the server already enforced its own ACLs too) for servers
451 that do not report the correct mode (do not support the
452 CIFS Unix Extensions).
456 Fix some small memory leaks in some unmount error paths. Fix major leak
457 of cache pages in readpages causing multiple read oriented stress
458 testcases (including fsx, and even large file copy) to fail over time.
462 Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
463 This allows files that differ only in case and improves performance of file
464 creation and file open to such servers. Fix semaphore conflict which causes
465 slow delete of open file to Samba (which unfortunately can cause an oplock
466 break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
470 fixes to cifs_readpages for fsx test case
474 Fix caching data integrity bug when extending file size especially when no
475 oplock on file. Fix spurious logging of valid already parsed mount options
476 that are parsed outside of the cifs vfs such as nosuid.
481 Connect to server when port number override not specified, and tcp port
482 unitialized. Reset search to restart at correct file when kernel routine
483 filldir returns error during large directory searches (readdir).
487 Fix caching problem when files opened by multiple clients in which
488 page cache could contain stale data, and write through did
489 not occur often enough while file was still open when read ahead
490 (read oplock) not allowed. Treat "sep=" when first mount option
491 as an override of comma as the default separator between mount
496 Allow passwords longer than 16 bytes. Allow null password string.
500 Gracefully clean up failed mounts when attempting to mount to servers such as
501 Windows 98 that terminate tcp sessions during protocol negotiation. Handle
502 embedded commas in mount parsing of passwords.
506 Invalidate local inode cached pages on oplock break and when last file
507 instance is closed so that the client does not continue using stale local
508 copy rather than later modified server copy of file. Do not reconnect
509 when server drops the tcp session prematurely before negotiate
510 protocol response. Fix oops in reopen_file when dentry freed. Allow
511 the support for CIFS Unix Extensions to be disabled via proc interface.
515 Fix hang in commit_write during reconnection of open files under heavy load.
516 Fix unload_nls oops in a mount failure path. Serialize writes to same socket
517 which also fixes any possible races when cifs signatures are enabled in SMBs
518 being sent out of signature sequence number order.
522 Fix byte range locking bug (endian problem) causing bad offset and
527 Fix oops (in send_sig) caused by CIFS unmount code trying to
528 wake up the demultiplex thread after it had exited. Do not log
529 error on harmless oplock release of closed handle.
533 Fix unsafe global variable usage and password hash failure on gcc 3.3.1
534 Fix problem reconnecting secondary mounts to same server after session
535 failure. Fix invalid dentry - race in mkdir when directory gets created
536 by another client between the lookup and mkdir.
540 Fix to list processing in reopen_files. Fix reconnection when server hung
541 but tcpip session still alive. Set proper timeout on socket read.
545 Add missing mount options including iocharset. SMP fixes in write and open.
546 Fix errors in reconnecting after TCP session failure. Fix module unloading
547 of default nls codepage
551 Active smb transactions should never go negative (fix double FreeXid). Fix
552 list processing in file routines. Check return code on kmalloc in open.
553 Fix spinlock usage for SMP.
557 Fix oops in reopen_files when invalid dentry. drop dentry on server rename
558 and on revalidate errors. Fix cases where pid is now tgid. Fix return code
559 on create hard link when server does not support them.
563 Fix scheduling while atomic error in getting inode info on newly created file.
564 Fix truncate of existing files opened with O_CREAT but not O_TRUNC set.
568 Fix oops on write to dead tcp session. Remove error log write for case when file open
569 O_CREAT but not O_EXCL
573 Fix non-POSIX behavior on rename of open file and delete of open file by taking
574 advantage of trans2 SetFileInfo rename facility if available on target server.
575 Retry on ENOSPC and EAGAIN socket errors.
579 Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix
580 allocation size miscalculation. After oplock token lost do not read through
585 Fix oops on empty file readahead. Fix for file size handling for locally cached files.
589 Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files
590 during auto reconnection to server after server recovered from failure.
594 Finish support for Linux 2.5 open/create changes, which removes the
595 redundant NTCreate/QPathInfo/close that was sent during file create.
596 Enable oplock by default. Enable packet signing by default (needed to
597 access many recent Windows servers)
601 Fix oops when mounting to long server names caused by inverted parms to kmalloc.
602 Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
603 we will choose a cifs user session (smb uid) that better matches the local
604 uid if a) the mount uid does not match the current uid and b) we have another
605 session to the same server (ip address) for a different mount which
606 matches the current local uid.
610 Add support for mknod of block or character devices. Fix oplock
611 code (distributed caching) to properly send response to oplock
616 Finish up CIFS packet digital signing for the default
617 NTLM security case. This should help Windows 2003
618 network interoperability since it is common for
619 packet signing to be required now. Fix statfs (stat -f)
620 which recently started returning errors due to
621 invalid value (-1 instead of 0) being set in the
622 struct kstatfs f_ffiles field.
626 Fix oops on stopping oplock thread when removing cifs when
631 Fix mount options for ro (readonly), uid, gid and file and directory mode.
635 Fix errors displayed on failed mounts to be more understandable.
636 Fixed various incorrect or misleading smb to posix error code mappings.
640 Fix display of NTFS DFS junctions to display as symlinks.
641 They are the network equivalent. Fix oops in
642 cifs_partialpagewrite caused by missing spinlock protection
643 of openfile linked list. Allow writebehind caching errors to
644 be returned to the application at file close.
648 Clean up options displayed in /proc/mounts by show_options to
649 be more consistent with other filesystems.
653 Fix delete of readonly file to Windows servers. Reflect
654 presence or absence of read only dos attribute in mode
655 bits for servers that do not support CIFS Unix extensions.
656 Fix shortened results on readdir of large directories to
657 servers supporting CIFS Unix extensions (caused by
658 incorrect resume key).
662 Fix truncate bug (set file size) that could cause hangs e.g. running fsx
666 unload nls if mount fails.
670 Add resume key support to search (readdir) code to workaround
671 Windows bug. Add /proc/fs/cifs/LookupCacheEnable which
672 allows disabling caching of attribute information for
677 Add more oplock handling (distributed caching code). Remove
678 dead code. Remove excessive stack space utilization from
683 Fix oops in get dfs referral (triggered when null path sent in to
684 mount). Add support for overriding rsize at mount time.
688 Fix buffer overrun in readdir which caused intermittent kernel oopses.
689 Fix writepage code to release kmap on write data. Allow "-ip=" new
690 mount option to be passed in on parameter distinct from the first part
691 (server name portion of) the UNC name. Allow override of the
692 tcp port of the target server via new mount option "-port="
696 Fix search handle leak on rewind. Fix setuid and gid so that they are
697 reflected in the local inode immediately. Cleanup of whitespace
698 to make 2.4 and 2.5 versions more consistent.
703 Fix signal sending so that captive thread (cifsd) exits on umount
704 (which was causing the warning in kmem_cache_free of the request buffers
705 at rmmod time). This had broken as a sideeffect of the recent global
706 kernel change to daemonize. Fix memory leak in readdir code which
707 showed up in "ls -R" (and applications that did search rewinding).
711 Reconnect tids and fids after session reconnection (still do not
712 reconnect byte range locks though). Fix problem caching
713 lookup information for directory inodes, improving performance,
714 especially in deep directory trees. Fix various build warnings.
718 Finish fixes to commit write for caching/readahead consistency. fsx
719 now works to Samba servers. Fix oops caused when readahead
720 was interrupted by a signal.
724 Fix data corruption (in partial page after truncate) that caused fsx to
725 fail to Windows servers. Cleaned up some extraneous error logging in
726 common error paths. Add generic sendfile support.
730 Fix memory leak in AllocMidQEntry.
731 Finish reconnection logic, so connection with server can be dropped
732 (or server rebooted) and the cifs client will reconnect.
736 Fix temporary socket leak when bad userid or password specified
737 (or other SMBSessSetup failure). Increase maximum buffer size to slightly
738 over 16K to allow negotiation of up to Samba and Windows server default read
739 sizes. Add support for readpages
743 Fix oops when username not passed in on mount. Extensive fixes and improvements
744 to error logging (strip redundant newlines, change debug macros to ensure newline
745 passed in and to be more consistent). Fix writepage wrong file handle problem,
746 a readonly file handle could be incorrectly used to attempt to write out
747 file updates through the page cache to multiply open files. This could cause
748 the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
749 shares to the same Windows server when using different usernames
750 (doing this to Samba servers worked but Windows was rejecting it) - now it is
751 possible to use different userids when connecting to the same server from a
752 Linux client. Fix oops when treeDisconnect called during unmount on
753 previously freed socket.
757 Fix oops in readpages caused by not setting address space operations in inode in
762 Includes support for deleting of open files and renaming over existing files (per POSIX
763 requirement). Add readlink support for Windows junction points (directory symlinks).
767 Changed read and write to go through pagecache. Added additional address space operations.
768 Memory mapped operations now working.
772 Added writepage code for additional memory mapping support. Fixed leak in xids causing
773 the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
774 every stat call. Additional formatting cleanup.
778 Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
782 Fixes from Zwane Mwaikambo for adding missing return code checking in a few places.
783 Also included a modified version of his fix to protect global list manipulation of
784 the smb session and tree connection and mid related global variables.
788 Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
789 changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
790 buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
794 More stylistic updates to better match kernel style. Add additional statistics
795 for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
796 and CIFS Packet Signing enablement.
800 Replace call to sleep_on with safer wait_on_event.
801 Make stylistic changes to better match kernel style recommendations.
802 Remove most typedef usage (except for the PDUs themselves).
806 Update mount so the -unc mount option is no longer required (the ip address can be specified
807 in a UNC style device name. Implementation of readpage/writepage started.
811 Fix intermittent problem with incorrect smb header checking on badly
812 fragmented tcp responses
816 Fixes to setting of allocation size and file size.
820 Various 2.5.38 fixes. Now works on 2.5.38
824 Prepare for 2.5 kernel merge. Remove ifdefs.
828 Socket buffer management fixes. Fix dual free.
832 Various big endian fixes for hardlinks and symlinks and also for dfs.
836 Various big endian fixes for servers with Unix extensions such as Samba
840 Various FindNext fixes for incorrect filenames on large directory searches on big endian
841 clients. basic posix file i/o tests now work on big endian machines, not just le
845 SessionSetup and NegotiateProtocol now work from Big Endian machines.
846 Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older
847 versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7).
851 Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
852 files now return the correct number of links on fstat as they are repeatedly linked and unlinked.
856 Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
857 session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
858 Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
859 (which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).
863 Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
864 it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
868 Rewrote much of connection and mount/unmount logic to handle bugs with
869 multiple uses to same share, multiple users to same server etc.
873 Fixed major problem with dentry corruption (missing call to dput)
877 Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
878 Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
879 although corresponding function not fully implemented in the vfs yet
883 Fixed dentry caching bug, misc. cleanup
887 Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
888 on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
889 Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
893 Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
894 and tested against Samba 2.2.5
899 1) Fixed lockrange to be correct (it was one byte too short)
901 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
902 show range as locked when there is a conflict with an existing lock.
904 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
905 in most cases. Eventually will offer optional ability to query server for the correct perms.
907 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
908 but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
911 4) Fixed error logging of valid mount options
913 5) Removed logging of password field.
915 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
916 and cleaned them up and made them more consistent with other cifs functions.
918 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
919 (with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
920 nor is the symlink support using the Unix extensions
922 8) Started adding the readlink and follow_link code
