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
6 cached files. Fix setxattr failure to certain Samba versions. Fix mount
7 of second share to disconnected server session (autoreconnect on this).
8 Add ability to modify cifs acls for handling chmod (when mounted with
13 Fix memory leak in statfs when mounted to very old servers (e.g.
14 Windows 9x). Add new feature "POSIX open" which allows servers
15 which support the current POSIX Extensions to provide better semantics
16 (e.g. delete for open files opened with posix open). Take into
17 account umask on posix mkdir not just older style mkdir. Add
18 ability to mount to IPC$ share (which allows CIFS named pipes to be
19 opened, read and written as if they were files). When 1st tree
20 connect fails (e.g. due to signing negotiation failure) fix
21 leak that causes cifsd not to stop and rmmod to fail to cleanup
22 cifs_request_buffers pool. Fix problem with POSIX Open/Mkdir on
23 bigendian architectures. Fix possible memory corruption when
24 EAGAIN returned on kern_recvmsg. Return better error if server
25 requires packet signing but client has disabled it. When mounted
26 with cifsacl mount option - mode bits are approximated based
27 on the contents of the ACL of the file or directory. When cifs
28 mount helper is missing convert make sure that UNC name
29 has backslash (not forward slash) between ip address of server
34 Fix NTLMv2 signing. NFS server mounted over cifs works (if cifs mount is
35 done with "serverino" mount option). Add support for POSIX Unlink
36 (helps with certain sharing violation cases when server such as
37 Samba supports newer POSIX CIFS Protocol Extensions). Add "nounix"
38 mount option to allow disabling the CIFS Unix Extensions for just
39 that mount. Fix hang on spinlock in find_writable_file (race when
40 reopening file after session crash). Byte range unlock request to
41 windows server could unlock more bytes (on server copy of file)
42 than intended if start of unlock request is well before start of
43 a previous byte range lock that we issued.
47 IPv6 support. Enable ipv6 addresses to be passed on mount (put the ipv6
48 address after the "ip=" mount option, at least until mount.cifs is fixed to
49 handle DNS host to ipv6 name translation). Accept override of uid or gid
50 on mount even when Unix Extensions are negotiated (it used to be ignored
51 when Unix Extensions were ignored). This allows users to override the
52 default uid and gid for files when they are certain that the uids or
53 gids on the server do not match those of the client. Make "sec=none"
54 mount override username (so that null user connection is attempted)
55 to match what documentation said. Support for very large reads, over 127K,
56 available to some newer servers (such as Samba 3.0.26 and later but
57 note that it also requires setting CIFSMaxBufSize at module install
58 time to a larger value which may hurt performance in some cases).
59 Make sign option force signing (or fail if server does not support it).
63 Fix mtime bouncing around from local idea of last write times to remote time.
64 Fix hang (in i_size_read) when simultaneous size update of same remote file
65 on smp system corrupts sequence number. Do not reread unnecessarily partial page
66 (which we are about to overwrite anyway) when writing out file opened rw.
67 When DOS attribute of file on non-Unix server's file changes on the server side
68 from read-only back to read-write, reflect this change in default file mode
69 (we had been leaving a file's mode read-only until the inode were reloaded).
70 Allow setting of attribute back to ATTR_NORMAL (removing readonly dos attribute
71 when archive dos attribute not set and we are changing mode back to writeable
72 on server which does not support the Unix Extensions). Remove read only dos
73 attribute on chmod when adding any write permission (ie on any of
74 user/group/other (not all of user/group/other ie 0222) when
75 mounted to windows. Add support for POSIX MkDir (slight performance
76 enhancement and eliminates the network race between the mkdir and set
77 path info of the mode).
82 Fix oops in list_del during mount caused by unaligned string.
83 Fix file corruption which could occur on some large file
84 copies caused by writepages page i/o completion bug.
85 Seek to SEEK_END forces check for update of file size for non-cached
86 files. Allow file size to be updated on remote extend of locally open,
87 non-cached file. Fix reconnect to newer Samba servers (or other servers
88 which support the CIFS Unix/POSIX extensions) so that we again tell the
89 server the Unix/POSIX cifs capabilities which we support (SetFSInfo).
90 Add experimental support for new POSIX Open/Mkdir (which returns
91 stat information on the open, and allows setting the mode).
95 Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
96 Allow null user to be specified on mount ("username="). Do not return
97 EINVAL on readdir when filldir fails due to overwritten blocksize
98 (fixes FC problem). Return error in rename 2nd attempt retry (ie report
99 if rename by handle also fails, after rename by path fails, we were
100 not reporting whether the retry worked or not). Fix NTLMv2 to
101 work to Windows servers (mount with option "sec=ntlmv2").
105 Do not time out lockw calls when using posix extensions. Do not
106 time out requests if server still responding reasonably fast
107 on requests on other threads. Improve POSIX locking emulation,
108 (lock cancel now works, and unlock of merged range works even
109 to Windows servers now). Fix oops on mount to lanman servers
110 (win9x, os/2 etc.) when null password. Do not send listxattr
111 (SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
112 problem (instantiate inodes/dentries in right order for readdir).
116 Rewritten sessionsetup support, including support for legacy SMB
117 session setup needed for OS/2 and older servers such as Windows 95 and 98.
118 Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
119 so we can do search (ls etc.) to OS/2. Do not send NTCreateX
120 or recent levels of FindFirst unless server says it supports NT SMBs
121 (instead use legacy equivalents from LANMAN dialect). Fix to allow
122 NTLMv2 authentication support (now can use stronger password hashing
123 on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
124 Allow override of global cifs security flags on mount via "sec=" option(s).
128 POSIX locking to servers which support CIFS POSIX Extensions
129 (disabled by default controlled by proc/fs/cifs/Experimental).
130 Handle conversion of long share names (especially Asian languages)
131 to Unicode during mount. Fix memory leak in sess struct on reconnect.
132 Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
133 cifs open which helps rare case when setpathinfo fails or server does
138 Fix slow oplock break when mounted to different servers at the same time and
139 the tids match and we try to find matching fid on wrong server. Fix read
140 looping when signing required by server (2.6.16 kernel only). Fix readdir
141 vs. rename race which could cause each to hang. Return . and .. even
142 if server does not. Allow searches to skip first three entries and
143 begin at any location. Fix oops in find_writeable_file.
147 Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
148 configure stronger authentication. Fix sfu symlinks so they can
149 be followed (not just recognized). Fix wraparound of bcc on
150 read responses when buffer size over 64K and also fix wrap of
151 max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
152 cifs_user_read and cifs_readpages (when EAGAIN on send of smb
153 on socket is returned over and over). Add POSIX (advisory) byte range
154 locking support (requires server with newest CIFS UNIX Extensions
155 to the protocol implemented). Slow down negprot slightly in port 139
156 RFC1001 case to give session_init time on buggy servers.
160 Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
161 of readpages by eliminating one extra memcpy. Allow update of file size
162 from remote server even if file is open for write as long as mount is
163 directio. Recognize share mode security and send NTLM encrypted password
164 on tree connect if share mode negotiated.
168 Defer close of a file handle slightly if pending writes depend on that handle
169 (this reduces the EBADF bad file handle errors that can be logged under heavy
170 stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
171 Fix SFU style symlinks and mknod needed for servers which do not support the
172 CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
173 dentries so files that the client sees as deleted but that later get created
174 on the server will be recognized. Add client side permission check on setattr.
175 Timeout stuck requests better (where server has never responded or sent corrupt
180 Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
181 to be smaller at first (but increasing) so large write performance performance
182 over GigE is better. Do not hang thread on illegal byte range lock response
183 from Windows (Windows can send an RFC1001 size which does not match smb size) by
184 allowing an SMBs TCP length to be up to a few bytes longer than it should be.
185 wsize and rsize can now be larger than negotiated buffer size if server
186 supports large readx/writex, even when directio mount flag not specified.
187 Write size will in many cases now be 16K instead of 4K which greatly helps
188 file copy performance on lightly loaded networks. Fix oops in dnotify
189 when experimental config flag enabled. Make cifsFYI more granular.
193 Fix readdir caching when unlink removes file in current search buffer,
194 and this is followed by a rewind search to just before the deleted entry.
195 Do not attempt to set ctime unless atime and/or mtime change requested
196 (most servers throw it away anyway). Fix length check of received smbs
197 to be more accurate. Fix big endian problem with mapchars mount option,
198 and with a field returned by statfs.
202 Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
203 For these older servers, add option for passing netbios name of server in
204 on mount (servernetbiosname). Add suspend support for power management, to
205 avoid cifsd thread preventing software suspend from working.
206 Add mount option for disabling the default behavior of sending byte range lock
207 requests to the server (necessary for certain applications which break with
208 mandatory lock behavior such as Evolution), and also mount option for
209 requesting case insensitive matching for path based requests (requesting
210 case sensitive is the default).
214 Add writepage performance improvements. Fix path name conversions
215 for long filenames on mounts which were done with "mapchars" mount option
216 specified. Ensure multiplex ids do not collide. Fix case in which
217 rmmod can oops if done soon after last unmount. Fix truncated
218 search (readdir) output when resume filename was a long filename.
219 Fix filename conversion when mapchars mount option was specified and
220 filename was a long filename.
224 Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
225 Do not oops if root user kills cifs oplock kernel thread or
226 kills the cifsd thread (NB: killing the cifs kernel threads is not
227 recommended, unmount and rmmod cifs will kill them when they are
228 no longer needed). Fix readdir to ASCII servers (ie older servers
229 which do not support Unicode) and also require asterisk.
230 Fix out of memory case in which data could be written one page
231 off in the page cache.
235 Fix caching problem, in which readdir of directory containing a file
236 which was cached could cause the file's time stamp to be updated
237 without invalidating the readahead data (so we could get stale
238 file data on the client for that file even as the server copy changed).
239 Cleanup response processing so cifsd can not loop when abnormally
245 Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
246 transact response for an SMB request and search entry split across two frames.
247 Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
248 as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
249 unless server explicitly claims to support them in CIFS Unix extensions
250 POSIX ACL capability bit. Fix packet signing when multiuser mounting with
251 different users from the same client to the same server. Fix oops in
252 cifs_close. Add mount option for remapping reserved characters in
253 filenames (also allow recognizing files with created by SFU which have any
254 of these seven reserved characters, except backslash, to be recognized).
255 Fix invalid transact2 message (we were sometimes trying to interpret
256 oplock breaks as SMB responses). Add ioctl for checking that the
257 current uid matches the uid of the mounter (needed by umount.cifs).
258 Reduce the number of large buffer allocations in cifs response processing
259 (significantly reduces memory pressure under heavy stress with multiple
260 processes accessing the same server at the same time).
264 Fix updates of DOS attributes and time fields so that files on NT4 servers
265 do not get marked delete on close. Display sizes of cifs buffer pools in
266 cifs stats. Fix oops in unmount when cifsd thread being killed by
267 shutdown. Add generic readv/writev and aio support. Report inode numbers
268 consistently in readdir and lookup (when serverino mount option is
269 specified use the inode number that the server reports - for both lookup
270 and readdir, otherwise by default the locally generated inode number is used
271 for inodes created in either path since servers are not always able to
272 provide unique inode numbers when exporting multiple volumes from under one
277 Allow new nouser_xattr mount parm to disable xattr support for user namespace.
278 Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
279 (mostly affects NT4 servers) by retry with handle based network operation.
280 Add new POSIX Query FS Info for returning statfs info more accurately.
281 Handle passwords with multiple commas in them.
285 Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
286 Fix capabilities flags for large readx so as to allow reads larger than 64K.
290 Add module init parm for large SMB buffer size (to allow it to be changed
291 from its default of 16K) which is especially useful for large file copy
292 when mounting with the directio mount option. Fix oops after
293 returning from mount when experimental ExtendedSecurity enabled and
294 SpnegoNegotiated returning invalid error. Fix case to retry better when
295 peek returns from 1 to 3 bytes on socket which should have more data.
296 Fixed path based calls (such as cifs lookup) to handle path names
297 longer than 530 (now can handle PATH_MAX). Fix pass through authentication
298 from Samba server to DC (Samba required dummy LM password).
302 Turn off DNOTIFY (directory change notification support) by default
303 (unless built with the experimental flag) to fix hang with KDE
304 file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
305 waiting on an SMB response) in SendReceive when session dies but
306 reconnects quickly from another task. Add module init parms for
307 minimum number of large and small network buffers in the buffer pools,
308 and for the maximum number of simultaneous requests.
312 Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
313 and other POSIX CIFS compliant servers. Fix error mapping for getfacl
314 to EOPNOTSUPP when server does not support posix acls on the wire. Fix
315 improperly zeroed buffer in CIFS Unix extensions set times call.
319 Fix internationalization problem in cifs readdir with filenames that map to
320 longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
321 for readdir to netapp servers. Fix search rewind (seek into readdir to return
322 non-consecutive entries). Do not do readdir when server negotiates
323 buffer size to small to fit filename. Add support for reading POSIX ACLs from
324 the server (add also acl and noacl mount options).
328 Optionally allow using server side inode numbers, rather than client generated
329 ones by specifying mount option "serverino" - this is required for some apps
330 to work which double check hardlinked files and have persistent inode numbers.
334 Multiple bigendian fixes. On little endian systems (for reconnect after
335 network failure) fix tcp session reconnect code so we do not try first
336 to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
337 as directories rather than symlinks because we can do follow link on them.
341 Add config option to enable XATTR (extended attribute) support, mapping
342 xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
343 minor fixes pointed out by the Stanford SWAT checker (mostly missing
344 or out of order NULL pointer checks in little used error paths).
348 Add new mount parm to control whether mode check (generic_permission) is done
349 on the client. If Unix extensions are enabled and the uids on the client
350 and server do not match, client permission checks are meaningless on
351 server uids that do not exist on the client (this does not affect the
352 normal ACL check which occurs on the server). Fix default uid
353 on mknod to match create and mkdir. Add optional mount parm to allow
354 override of the default uid behavior (in which the server sets the uid
355 and gid of newly created files). Normally for network filesystem mounts
356 user want the server to set the uid/gid on newly created files (rather than
357 using uid of the client processes you would in a local filesystem).
361 Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
362 info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
363 (in build_wildcard_path_from_dentry). Fix mknod to pass type field
364 (block/char/fifo) properly. Remove spurious mount warning log entry when
365 credentials passed as mount argument. Set major/minor device number in
366 inode for block and char devices when unix extensions enabled.
370 Fix /proc/fs/cifs/Stats and DebugData display to handle larger
371 amounts of return data. Properly limit requests to MAX_REQ (50
372 is the usual maximum active multiplex SMB/CIFS requests per server).
373 Do not kill cifsd (and thus hurt the other SMB session) when more than one
374 session to the same server (but with different userids) exists and one
375 of the two user's smb sessions is being removed while leaving the other.
376 Do not loop reconnecting in cifsd demultiplex thread when admin
377 kills the thread without going through unmount.
381 Do not rename hardlinked files (since that should be a noop). Flush
382 cached write behind data when reopening a file after session abend,
383 except when already in write. Grab per socket sem during reconnect
384 to avoid oops in sendmsg if overlapping with reconnect. Do not
385 reset cached inode file size on readdir for files open for write on
391 Update number of blocks in file so du command is happier (in Linux a fake
392 blocksize of 512 is required for calculating number of blocks in inode).
393 Fix prepare write of partial pages to read in data from server if possible.
394 Fix race on tcpStatus field between unmount and reconnection code, causing
395 cifsd process sometimes to hang around forever. Improve out of memory
396 checks in cifs_filldir
400 Fix incorrect file size in file handle based setattr on big endian hardware.
401 Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
402 and closing file structs in writepage/partialpagewrite. Add statistics
403 for each mounted share (new menuconfig option). Fix endianness problem in
404 volume information displayed in /proc/fs/cifs/DebugData (only affects
405 affects big endian architectures). Prevent renames while constructing
406 path names for open, mkdir and rmdir.
410 Change to mempools for alloc smb request buffers and multiplex structs
411 to better handle low memory problems (and potential deadlocks).
415 Fix incomplete listings of large directories on Samba servers when Unix
416 extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
417 rename deadlock when writing out dirty pages at same time.
421 Fix open of files in which O_CREATE can cause the mode to change in
422 some cases. Fix case in which retry of write overlaps file close.
423 Fix PPC64 build error. Reduce excessive stack usage in smb password
424 hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
428 Fixes for large file copy, signal handling, socket retry, buffer
429 allocation and low memory situations.
433 Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
434 also now allowing support for specifying client netbiosname. NT4 support added.
438 Fix reconnection (and certain failed mounts) to properly wake up the
439 blocked users thread so it does not seem hung (in some cases was blocked
440 until the cifs receive timeout expired). Fix spurious error logging
441 to kernel log when application with open network files killed.
445 Fix /proc/fs module unload warning message (that could be logged
446 to the kernel log). Fix intermittent failure in connectathon
447 test7 (hardlink count not immediately refreshed in case in which
448 inode metadata can be incorrectly kept cached when time near zero)
452 Allow file_mode and dir_mode (specified at mount time) to be enforced
453 locally (the server already enforced its own ACLs too) for servers
454 that do not report the correct mode (do not support the
455 CIFS Unix Extensions).
459 Fix some small memory leaks in some unmount error paths. Fix major leak
460 of cache pages in readpages causing multiple read oriented stress
461 testcases (including fsx, and even large file copy) to fail over time.
465 Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
466 This allows files that differ only in case and improves performance of file
467 creation and file open to such servers. Fix semaphore conflict which causes
468 slow delete of open file to Samba (which unfortunately can cause an oplock
469 break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
473 fixes to cifs_readpages for fsx test case
477 Fix caching data integrity bug when extending file size especially when no
478 oplock on file. Fix spurious logging of valid already parsed mount options
479 that are parsed outside of the cifs vfs such as nosuid.
484 Connect to server when port number override not specified, and tcp port
485 unitialized. Reset search to restart at correct file when kernel routine
486 filldir returns error during large directory searches (readdir).
490 Fix caching problem when files opened by multiple clients in which
491 page cache could contain stale data, and write through did
492 not occur often enough while file was still open when read ahead
493 (read oplock) not allowed. Treat "sep=" when first mount option
494 as an override of comma as the default separator between mount
499 Allow passwords longer than 16 bytes. Allow null password string.
503 Gracefully clean up failed mounts when attempting to mount to servers such as
504 Windows 98 that terminate tcp sessions during protocol negotiation. Handle
505 embedded commas in mount parsing of passwords.
509 Invalidate local inode cached pages on oplock break and when last file
510 instance is closed so that the client does not continue using stale local
511 copy rather than later modified server copy of file. Do not reconnect
512 when server drops the tcp session prematurely before negotiate
513 protocol response. Fix oops in reopen_file when dentry freed. Allow
514 the support for CIFS Unix Extensions to be disabled via proc interface.
518 Fix hang in commit_write during reconnection of open files under heavy load.
519 Fix unload_nls oops in a mount failure path. Serialize writes to same socket
520 which also fixes any possible races when cifs signatures are enabled in SMBs
521 being sent out of signature sequence number order.
525 Fix byte range locking bug (endian problem) causing bad offset and
530 Fix oops (in send_sig) caused by CIFS unmount code trying to
531 wake up the demultiplex thread after it had exited. Do not log
532 error on harmless oplock release of closed handle.
536 Fix unsafe global variable usage and password hash failure on gcc 3.3.1
537 Fix problem reconnecting secondary mounts to same server after session
538 failure. Fix invalid dentry - race in mkdir when directory gets created
539 by another client between the lookup and mkdir.
543 Fix to list processing in reopen_files. Fix reconnection when server hung
544 but tcpip session still alive. Set proper timeout on socket read.
548 Add missing mount options including iocharset. SMP fixes in write and open.
549 Fix errors in reconnecting after TCP session failure. Fix module unloading
550 of default nls codepage
554 Active smb transactions should never go negative (fix double FreeXid). Fix
555 list processing in file routines. Check return code on kmalloc in open.
556 Fix spinlock usage for SMP.
560 Fix oops in reopen_files when invalid dentry. drop dentry on server rename
561 and on revalidate errors. Fix cases where pid is now tgid. Fix return code
562 on create hard link when server does not support them.
566 Fix scheduling while atomic error in getting inode info on newly created file.
567 Fix truncate of existing files opened with O_CREAT but not O_TRUNC set.
571 Fix oops on write to dead tcp session. Remove error log write for case when file open
572 O_CREAT but not O_EXCL
576 Fix non-POSIX behavior on rename of open file and delete of open file by taking
577 advantage of trans2 SetFileInfo rename facility if available on target server.
578 Retry on ENOSPC and EAGAIN socket errors.
582 Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix
583 allocation size miscalculation. After oplock token lost do not read through
588 Fix oops on empty file readahead. Fix for file size handling for locally cached files.
592 Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files
593 during auto reconnection to server after server recovered from failure.
597 Finish support for Linux 2.5 open/create changes, which removes the
598 redundant NTCreate/QPathInfo/close that was sent during file create.
599 Enable oplock by default. Enable packet signing by default (needed to
600 access many recent Windows servers)
604 Fix oops when mounting to long server names caused by inverted parms to kmalloc.
605 Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
606 we will choose a cifs user session (smb uid) that better matches the local
607 uid if a) the mount uid does not match the current uid and b) we have another
608 session to the same server (ip address) for a different mount which
609 matches the current local uid.
613 Add support for mknod of block or character devices. Fix oplock
614 code (distributed caching) to properly send response to oplock
619 Finish up CIFS packet digital signing for the default
620 NTLM security case. This should help Windows 2003
621 network interoperability since it is common for
622 packet signing to be required now. Fix statfs (stat -f)
623 which recently started returning errors due to
624 invalid value (-1 instead of 0) being set in the
625 struct kstatfs f_ffiles field.
629 Fix oops on stopping oplock thread when removing cifs when
634 Fix mount options for ro (readonly), uid, gid and file and directory mode.
638 Fix errors displayed on failed mounts to be more understandable.
639 Fixed various incorrect or misleading smb to posix error code mappings.
643 Fix display of NTFS DFS junctions to display as symlinks.
644 They are the network equivalent. Fix oops in
645 cifs_partialpagewrite caused by missing spinlock protection
646 of openfile linked list. Allow writebehind caching errors to
647 be returned to the application at file close.
651 Clean up options displayed in /proc/mounts by show_options to
652 be more consistent with other filesystems.
656 Fix delete of readonly file to Windows servers. Reflect
657 presence or absence of read only dos attribute in mode
658 bits for servers that do not support CIFS Unix extensions.
659 Fix shortened results on readdir of large directories to
660 servers supporting CIFS Unix extensions (caused by
661 incorrect resume key).
665 Fix truncate bug (set file size) that could cause hangs e.g. running fsx
669 unload nls if mount fails.
673 Add resume key support to search (readdir) code to workaround
674 Windows bug. Add /proc/fs/cifs/LookupCacheEnable which
675 allows disabling caching of attribute information for
680 Add more oplock handling (distributed caching code). Remove
681 dead code. Remove excessive stack space utilization from
686 Fix oops in get dfs referral (triggered when null path sent in to
687 mount). Add support for overriding rsize at mount time.
691 Fix buffer overrun in readdir which caused intermittent kernel oopses.
692 Fix writepage code to release kmap on write data. Allow "-ip=" new
693 mount option to be passed in on parameter distinct from the first part
694 (server name portion of) the UNC name. Allow override of the
695 tcp port of the target server via new mount option "-port="
699 Fix search handle leak on rewind. Fix setuid and gid so that they are
700 reflected in the local inode immediately. Cleanup of whitespace
701 to make 2.4 and 2.5 versions more consistent.
706 Fix signal sending so that captive thread (cifsd) exits on umount
707 (which was causing the warning in kmem_cache_free of the request buffers
708 at rmmod time). This had broken as a sideeffect of the recent global
709 kernel change to daemonize. Fix memory leak in readdir code which
710 showed up in "ls -R" (and applications that did search rewinding).
714 Reconnect tids and fids after session reconnection (still do not
715 reconnect byte range locks though). Fix problem caching
716 lookup information for directory inodes, improving performance,
717 especially in deep directory trees. Fix various build warnings.
721 Finish fixes to commit write for caching/readahead consistency. fsx
722 now works to Samba servers. Fix oops caused when readahead
723 was interrupted by a signal.
727 Fix data corruption (in partial page after truncate) that caused fsx to
728 fail to Windows servers. Cleaned up some extraneous error logging in
729 common error paths. Add generic sendfile support.
733 Fix memory leak in AllocMidQEntry.
734 Finish reconnection logic, so connection with server can be dropped
735 (or server rebooted) and the cifs client will reconnect.
739 Fix temporary socket leak when bad userid or password specified
740 (or other SMBSessSetup failure). Increase maximum buffer size to slightly
741 over 16K to allow negotiation of up to Samba and Windows server default read
742 sizes. Add support for readpages
746 Fix oops when username not passed in on mount. Extensive fixes and improvements
747 to error logging (strip redundant newlines, change debug macros to ensure newline
748 passed in and to be more consistent). Fix writepage wrong file handle problem,
749 a readonly file handle could be incorrectly used to attempt to write out
750 file updates through the page cache to multiply open files. This could cause
751 the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
752 shares to the same Windows server when using different usernames
753 (doing this to Samba servers worked but Windows was rejecting it) - now it is
754 possible to use different userids when connecting to the same server from a
755 Linux client. Fix oops when treeDisconnect called during unmount on
756 previously freed socket.
760 Fix oops in readpages caused by not setting address space operations in inode in
765 Includes support for deleting of open files and renaming over existing files (per POSIX
766 requirement). Add readlink support for Windows junction points (directory symlinks).
770 Changed read and write to go through pagecache. Added additional address space operations.
771 Memory mapped operations now working.
775 Added writepage code for additional memory mapping support. Fixed leak in xids causing
776 the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
777 every stat call. Additional formatting cleanup.
781 Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
785 Fixes from Zwane Mwaikambo for adding missing return code checking in a few places.
786 Also included a modified version of his fix to protect global list manipulation of
787 the smb session and tree connection and mid related global variables.
791 Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
792 changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
793 buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
797 More stylistic updates to better match kernel style. Add additional statistics
798 for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
799 and CIFS Packet Signing enablement.
803 Replace call to sleep_on with safer wait_on_event.
804 Make stylistic changes to better match kernel style recommendations.
805 Remove most typedef usage (except for the PDUs themselves).
809 Update mount so the -unc mount option is no longer required (the ip address can be specified
810 in a UNC style device name. Implementation of readpage/writepage started.
814 Fix intermittent problem with incorrect smb header checking on badly
815 fragmented tcp responses
819 Fixes to setting of allocation size and file size.
823 Various 2.5.38 fixes. Now works on 2.5.38
827 Prepare for 2.5 kernel merge. Remove ifdefs.
831 Socket buffer management fixes. Fix dual free.
835 Various big endian fixes for hardlinks and symlinks and also for dfs.
839 Various big endian fixes for servers with Unix extensions such as Samba
843 Various FindNext fixes for incorrect filenames on large directory searches on big endian
844 clients. basic posix file i/o tests now work on big endian machines, not just le
848 SessionSetup and NegotiateProtocol now work from Big Endian machines.
849 Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older
850 versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7).
854 Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
855 files now return the correct number of links on fstat as they are repeatedly linked and unlinked.
859 Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
860 session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
861 Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
862 (which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).
866 Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
867 it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
871 Rewrote much of connection and mount/unmount logic to handle bugs with
872 multiple uses to same share, multiple users to same server etc.
876 Fixed major problem with dentry corruption (missing call to dput)
880 Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
881 Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
882 although corresponding function not fully implemented in the vfs yet
886 Fixed dentry caching bug, misc. cleanup
890 Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
891 on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
892 Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
896 Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
897 and tested against Samba 2.2.5
902 1) Fixed lockrange to be correct (it was one byte too short)
904 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
905 show range as locked when there is a conflict with an existing lock.
907 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
908 in most cases. Eventually will offer optional ability to query server for the correct perms.
910 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
911 but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
914 4) Fixed error logging of valid mount options
916 5) Removed logging of password field.
918 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
919 and cleaned them up and made them more consistent with other cifs functions.
921 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
922 (with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
923 nor is the symlink support using the Unix extensions
925 8) Started adding the readlink and follow_link code
