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