3 Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
4 transact response for an SMB request and search entry split across two frames.
5 Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
6 as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
7 unless server explicitly claims to support them in CIFS Unix extensions
8 POSIX ACL capability bit.
12 Fix updates of DOS attributes and time fields so that files on NT4 servers
13 do not get marked delete on close. Display sizes of cifs buffer pools in
14 cifs stats. Fix oops in unmount when cifsd thread being killed by
15 shutdown. Add generic readv/writev and aio support. Report inode numbers
16 consistently in readdir and lookup (when serverino mount option is
17 specified use the inode number that the server reports - for both lookup
18 and readdir, otherwise by default the locally generated inode number is used
19 for inodes created in either path since servers are not always able to
20 provide unique inode numbers when exporting multiple volumes from under one
25 Allow new nouser_xattr mount parm to disable xattr support for user namespace.
26 Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
27 (mostly affects NT4 servers) by retry with handle based network operation.
28 Add new POSIX Query FS Info for returning statfs info more accurately.
29 Handle passwords with multiple commas in them.
33 Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
34 Fix capabilities flags for large readx so as to allow reads larger than 64K.
38 Add module init parm for large SMB buffer size (to allow it to be changed
39 from its default of 16K) which is especially useful for large file copy
40 when mounting with the directio mount option. Fix oops after
41 returning from mount when experimental ExtendedSecurity enabled and
42 SpnegoNegotiated returning invalid error. Fix case to retry better when
43 peek returns from 1 to 3 bytes on socket which should have more data.
44 Fixed path based calls (such as cifs lookup) to handle path names
45 longer than 530 (now can handle PATH_MAX). Fix pass through authentication
46 from Samba server to DC (Samba required dummy LM password).
50 Turn off DNOTIFY (directory change notification support) by default
51 (unless built with the experimental flag) to fix hang with KDE
52 file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
53 waiting on an SMB response) in SendReceive when session dies but
54 reconnects quickly from another task. Add module init parms for
55 minimum number of large and small network buffers in the buffer pools,
56 and for the maximum number of simultaneous requests.
60 Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
61 and other POSIX CIFS compliant servers. Fix error mapping for getfacl
62 to EOPNOTSUPP when server does not support posix acls on the wire. Fix
63 improperly zeroed buffer in CIFS Unix extensions set times call.
67 Fix internationlization problem in cifs readdir with filenames that map to
68 longer UTF8 strings than the string on the wire was in Unicode. Add workaround
69 for readdir to netapp servers. Fix search rewind (seek into readdir to return
70 non-consecutive entries). Do not do readdir when server negotiates
71 buffer size to small to fit filename. Add support for reading POSIX ACLs from
72 the server (add also acl and noacl mount options).
76 Optionally allow using server side inode numbers, rather than client generated
77 ones by specifying mount option "serverino" - this is required for some apps
78 to work which double check hardlinked files and have persistent inode numbers.
82 Multiple bigendian fixes. On little endian systems (for reconnect after
83 network failure) fix tcp session reconnect code so we do not try first
84 to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
85 as directories rather than symlinks because we can do follow link on them.
89 Add config option to enable XATTR (extended attribute) support, mapping
90 xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
91 minor fixes pointed out by the Stanford SWAT checker (mostly missing
92 or out of order NULL pointer checks in little used error paths).
96 Add new mount parm to control whether mode check (generic_permission) is done
97 on the client. If Unix extensions are enabled and the uids on the client
98 and server do not match, client permission checks are meaningless on
99 server uids that do not exist on the client (this does not affect the
100 normal ACL check which occurs on the server). Fix default uid
101 on mknod to match create and mkdir. Add optional mount parm to allow
102 override of the default uid behavior (in which the server sets the uid
103 and gid of newly created files). Normally for network filesystem mounts
104 user want the server to set the uid/gid on newly created files (rather than
105 using uid of the client processes you would in a local filesystem).
109 Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
110 info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
111 (in build_wildcard_path_from_dentry). Fix mknod to pass type field
112 (block/char/fifo) properly. Remove spurious mount warning log entry when
113 credentials passed as mount argument. Set major/minor device number in
114 inode for block and char devices when unix extensions enabled.
118 Fix /proc/fs/cifs/Stats and DebugData display to handle larger
119 amounts of return data. Properly limit requests to MAX_REQ (50
120 is the usual maximum active multiplex SMB/CIFS requests per server).
121 Do not kill cifsd (and thus hurt the other SMB session) when more than one
122 session to the same server (but with different userids) exists and one
123 of the two user's smb sessions is being removed while leaving the other.
124 Do not loop reconnecting in cifsd demultiplex thread when admin
125 kills the thread without going through unmount.
129 Do not rename hardlinked files (since that should be a noop). Flush
130 cached write behind data when reopening a file after session abend,
131 except when already in write. Grab per socket sem during reconnect
132 to avoid oops in sendmsg if overlapping with reconnect. Do not
133 reset cached inode file size on readdir for files open for write on
139 Update number of blocks in file so du command is happier (in Linux a fake
140 blocksize of 512 is required for calculating number of blocks in inode).
141 Fix prepare write of partial pages to read in data from server if possible.
142 Fix race on tcpStatus field between unmount and reconnection code, causing
143 cifsd process sometimes to hang around forever. Improve out of memory
144 checks in cifs_filldir
148 Fix incorrect file size in file handle based setattr on big endian hardware.
149 Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
150 and closing file structs in writepage/partialpagewrite. Add statistics
151 for each mounted share (new menuconfig option). Fix endianness problem in
152 volume information displayed in /proc/fs/cifs/DebugData (only affects
153 affects big endian architectures). Prevent renames while constructing
154 path names for open, mkdir and rmdir.
158 Change to mempools for alloc smb request buffers and multiplex structs
159 to better handle low memory problems (and potential deadlocks).
163 Fix incomplete listings of large directories on Samba servers when Unix
164 extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
165 rename deadlock when writing out dirty pages at same time.
169 Fix open of files in which O_CREATE can cause the mode to change in
170 some cases. Fix case in which retry of write overlaps file close.
171 Fix PPC64 build error. Reduce excessive stack usage in smb password
172 hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
176 Fixes for large file copy, signal handling, socket retry, buffer
177 allocation and low memory situations.
181 Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
182 also now allowing support for specifying client netbiosname. NT4 support added.
186 Fix reconnection (and certain failed mounts) to properly wake up the
187 blocked users thread so it does not seem hung (in some cases was blocked
188 until the cifs receive timeout expired). Fix spurious error logging
189 to kernel log when application with open network files killed.
193 Fix /proc/fs module unload warning message (that could be logged
194 to the kernel log). Fix intermittent failure in connectathon
195 test7 (hardlink count not immediately refreshed in case in which
196 inode metadata can be incorrectly kept cached when time near zero)
200 Allow file_mode and dir_mode (specified at mount time) to be enforced
201 locally (the server already enforced its own ACLs too) for servers
202 that do not report the correct mode (do not support the
203 CIFS Unix Extensions).
207 Fix some small memory leaks in some unmount error paths. Fix major leak
208 of cache pages in readpages causing multiple read oriented stress
209 testcases (including fsx, and even large file copy) to fail over time.
213 Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
214 This allows files that differ only in case and improves performance of file
215 creation and file open to such servers. Fix semaphore conflict which causes
216 slow delete of open file to Samba (which unfortunately can cause an oplock
217 break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
221 fixes to cifs_readpages for fsx test case
225 Fix caching data integrity bug when extending file size especially when no
226 oplock on file. Fix spurious logging of valid already parsed mount options
227 that are parsed outside of the cifs vfs such as nosuid.
232 Connect to server when port number override not specified, and tcp port
233 unitialized. Reset search to restart at correct file when kernel routine
234 filldir returns error during large directory searches (readdir).
238 Fix caching problem when files opened by multiple clients in which
239 page cache could contain stale data, and write through did
240 not occur often enough while file was still open when read ahead
241 (read oplock) not allowed. Treat "sep=" when first mount option
242 as an overrride of comma as the default separator between mount
247 Allow passwords longer than 16 bytes. Allow null password string.
251 Gracefully clean up failed mounts when attempting to mount to servers such as
252 Windows 98 that terminate tcp sessions during prototocol negotiation. Handle
253 embedded commas in mount parsing of passwords.
257 Invalidate local inode cached pages on oplock break and when last file
258 instance is closed so that the client does not continue using stale local
259 copy rather than later modified server copy of file. Do not reconnect
260 when server drops the tcp session prematurely before negotiate
261 protocol response. Fix oops in roepen_file when dentry freed. Allow
262 the support for CIFS Unix Extensions to be disabled via proc interface.
266 Fix hang in commit_write during reconnection of open files under heavy load.
267 Fix unload_nls oops in a mount failure path. Serialize writes to same socket
268 which also fixes any possible races when cifs signatures are enabled in SMBs
269 being sent out of signature sequence number order.
273 Fix byte range locking bug (endian problem) causing bad offset and
278 Fix oops (in send_sig) caused by CIFS unmount code trying to
279 wake up the demultiplex thread after it had exited. Do not log
280 error on harmless oplock release of closed handle.
284 Fix unsafe global variable usage and password hash failure on gcc 3.3.1
285 Fix problem reconnecting secondary mounts to same server after session
286 failure. Fix invalid dentry - race in mkdir when directory gets created
287 by another client between the lookup and mkdir.
291 Fix to list processing in reopen_files. Fix reconnection when server hung
292 but tcpip session still alive. Set proper timeout on socket read.
296 Add missing mount options including iocharset. SMP fixes in write and open.
297 Fix errors in reconnecting after TCP session failure. Fix module unloading
298 of default nls codepage
302 Active smb transactions should never go negative (fix double FreeXid). Fix
303 list processing in file routines. Check return code on kmalloc in open.
304 Fix spinlock usage for SMP.
308 Fix oops in reopen_files when invalid dentry. drop dentry on server rename
309 and on revalidate errors. Fix cases where pid is now tgid. Fix return code
310 on create hard link when server does not support them.
314 Fix scheduling while atomic error in getting inode info on newly created file.
315 Fix truncate of existing files opened with O_CREAT but not O_TRUNC set.
319 Fix oops on write to dead tcp session. Remove error log write for case when file open
320 O_CREAT but not O_EXCL
324 Fix non-POSIX behavior on rename of open file and delete of open file by taking
325 advantage of trans2 SetFileInfo rename facility if available on target server.
326 Retry on ENOSPC and EAGAIN socket errors.
330 Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix
331 allocation size miscalculation. After oplock token lost do not read through
336 Fix oops on empty file readahead. Fix for file size handling for locally cached files.
340 Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files
341 during auto reconnection to server after server recovered from failure.
345 Finish support for Linux 2.5 open/create changes, which removes the
346 redundant NTCreate/QPathInfo/close that was sent during file create.
347 Enable oplock by default. Enable packet signing by default (needed to
348 access many recent Windows servers)
352 Fix oops when mounting to long server names caused by inverted parms to kmalloc.
353 Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
354 we will choose a cifs user session (smb uid) that better matches the local
355 uid if a) the mount uid does not match the current uid and b) we have another
356 session to the same server (ip address) for a different mount which
357 matches the current local uid.
361 Add support for mknod of block or character devices. Fix oplock
362 code (distributed caching) to properly send response to oplock
367 Finish up CIFS packet digital signing for the default
368 NTLM security case. This should help Windows 2003
369 network interoperability since it is common for
370 packet signing to be required now. Fix statfs (stat -f)
371 which recently started returning errors due to
372 invalid value (-1 instead of 0) being set in the
373 struct kstatfs f_ffiles field.
377 Fix oops on stopping oplock thread when removing cifs when
382 Fix mount options for ro (readonly), uid, gid and file and directory mode.
386 Fix errors displayed on failed mounts to be more understandable.
387 Fixed various incorrect or misleading smb to posix error code mappings.
391 Fix display of NTFS DFS junctions to display as symlinks.
392 They are the network equivalent. Fix oops in
393 cifs_partialpagewrite caused by missing spinlock protection
394 of openfile linked list. Allow writebehind caching errors to
395 be returned to the application at file close.
399 Clean up options displayed in /proc/mounts by show_options to
400 be more consistent with other filesystems.
404 Fix delete of readonly file to Windows servers. Reflect
405 presence or absence of read only dos attribute in mode
406 bits for servers that do not support CIFS Unix extensions.
407 Fix shortened results on readdir of large directories to
408 servers supporting CIFS Unix extensions (caused by
409 incorrect resume key).
413 Fix truncate bug (set file size) that could cause hangs e.g. running fsx
417 unload nls if mount fails.
421 Add resume key support to search (readdir) code to workaround
422 Windows bug. Add /proc/fs/cifs/LookupCacheEnable which
423 allows disabling caching of attribute information for
428 Add more oplock handling (distributed caching code). Remove
429 dead code. Remove excessive stack space utilization from
434 Fix oops in get dfs referral (triggered when null path sent in to
435 mount). Add support for overriding rsize at mount time.
439 Fix buffer overrun in readdir which caused intermittent kernel oopses.
440 Fix writepage code to release kmap on write data. Allow "-ip=" new
441 mount option to be passed in on parameter distinct from the first part
442 (server name portion of) the UNC name. Allow override of the
443 tcp port of the target server via new mount option "-port="
447 Fix search handle leak on rewind. Fix setuid and gid so that they are
448 reflected in the local inode immediately. Cleanup of whitespace
449 to make 2.4 and 2.5 versions more consistent.
454 Fix signal sending so that captive thread (cifsd) exits on umount
455 (which was causing the warning in kmem_cache_free of the request buffers
456 at rmmod time). This had broken as a sideeffect of the recent global
457 kernel change to daemonize. Fix memory leak in readdir code which
458 showed up in "ls -R" (and applications that did search rewinding).
462 Reconnect tids and fids after session reconnection (still do not
463 reconnect byte range locks though). Fix problem caching
464 lookup information for directory inodes, improving performance,
465 especially in deep directory trees. Fix various build warnings.
469 Finish fixes to commit write for caching/readahead consistency. fsx
470 now works to Samba servers. Fix oops caused when readahead
471 was interrupted by a signal.
475 Fix data corruption (in partial page after truncate) that caused fsx to
476 fail to Windows servers. Cleaned up some extraneous error logging in
477 common error paths. Add generic sendfile support.
481 Fix memory leak in AllocMidQEntry.
482 Finish reconnection logic, so connection with server can be dropped
483 (or server rebooted) and the cifs client will reconnect.
487 Fix temporary socket leak when bad userid or password specified
488 (or other SMBSessSetup failure). Increase maximum buffer size to slightly
489 over 16K to allow negotiation of up to Samba and Windows server default read
490 sizes. Add support for readpages
494 Fix oops when username not passed in on mount. Extensive fixes and improvements
495 to error logging (strip redundant newlines, change debug macros to ensure newline
496 passed in and to be more consistent). Fix writepage wrong file handle problem,
497 a readonly file handle could be incorrectly used to attempt to write out
498 file updates through the page cache to multiply open files. This could cause
499 the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
500 shares to the same Windows server when using different usernames
501 (doing this to Samba servers worked but Windows was rejecting it) - now it is
502 possible to use different userids when connecting to the same server from a
503 Linux client. Fix oops when treeDisconnect called during unmount on
504 previously freed socket.
508 Fix oops in readpages caused by not setting address space operations in inode in
513 Includes support for deleting of open files and renaming over existing files (per POSIX
514 requirement). Add readlink support for Windows junction points (directory symlinks).
518 Changed read and write to go through pagecache. Added additional address space operations.
519 Memory mapped operations now working.
523 Added writepage code for additional memory mapping support. Fixed leak in xids causing
524 the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
525 every stat call. Additional formatting cleanup.
529 Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
533 Fixes from Zwane Mwaikambo for adding missing return code checking in a few places.
534 Also included a modified version of his fix to protect global list manipulation of
535 the smb session and tree connection and mid related global variables.
539 Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
540 changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
541 buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
545 More stylistic updates to better match kernel style. Add additional statistics
546 for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
547 and CIFS Packet Signing enablement.
551 Replace call to sleep_on with safer wait_on_event.
552 Make stylistic changes to better match kernel style recommendations.
553 Remove most typedef usage (except for the PDUs themselves).
557 Update mount so the -unc mount option is no longer required (the ip address can be specified
558 in a UNC style device name. Implementation of readpage/writepage started.
562 Fix intermittent problem with incorrect smb header checking on badly
563 fragmented tcp responses
567 Fixes to setting of allocation size and file size.
571 Various 2.5.38 fixes. Now works on 2.5.38
575 Prepare for 2.5 kernel merge. Remove ifdefs.
579 Socket buffer management fixes. Fix dual free.
583 Various big endian fixes for hardlinks and symlinks and also for dfs.
587 Various big endian fixes for servers with Unix extensions such as Samba
591 Various FindNext fixes for incorrect filenames on large directory searches on big endian
592 clients. basic posix file i/o tests now work on big endian machines, not just le
596 SessionSetup and NegotiateProtocol now work from Big Endian machines.
597 Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older
598 versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7).
602 Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
603 files now return the correct rumber of links on fstat as they are repeatedly linked and unlinked.
607 Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
608 session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
609 Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
610 (which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).
614 Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
615 it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
619 Rewrote much of connection and mount/unmount logic to handle bugs with
620 multiple uses to same share, multiple users to same server etc.
624 Fixed major problem with dentry corruption (missing call to dput)
628 Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
629 Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
630 although corresponding function not fully implemented in the vfs yet
634 Fixed dentry caching bug, misc. cleanup
638 Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
639 on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
640 Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
644 Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
645 and tested against Samba 2.2.5
650 1) Fixed lockrange to be correct (it was one byte too short)
652 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
653 show range as locked when there is a conflict with an existing lock.
655 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
656 in most cases. Eventually will offer optional ability to query server for the correct perms.
658 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
659 but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
662 4) Fixed error logging of valid mount options
664 5) Removed logging of password field.
666 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
667 and cleaned them up and made them more consistent with other cifs functions.
669 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
670 (with or without Unix exentions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
671 nor is the symlink support using the Unix extensions
673 8) Started adding the readlink and follow_link code
