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