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