  1. Verison 1.48
  2. ------------
  3. Fix mtime bouncing around from local idea of last write times to remote time.
  4. Fix hang (in i_size_read) when simultaneous size update of same remote file
  5. on smp system corrupts sequence number. Do not reread unnecessarily partial page
  6. (which we are about to overwrite anyway) when writing out file opened rw.
  7. When DOS attribute of file on non-Unix server's file changes on the server side
  8. from read-only back to read-write, reflect this change in default file mode
  9. (we had been leaving a file's mode read-only until the inode were reloaded).
  10. Allow setting of attribute back to ATTR_NORMAL (removing readonly dos attribute
  11. when archive dos attribute not set and we are changing mode back to writeable
  12. on server which does not support the Unix Extensions).
  13. Version 1.47
  14. ------------
  15. Fix oops in list_del during mount caused by unaligned string.
  16. Fix file corruption which could occur on some large file
  17. copies caused by writepages page i/o completion bug.
  18. Seek to SEEK_END forces check for update of file size for non-cached
  19. files. Allow file size to be updated on remote extend of locally open,
  20. non-cached file. Fix reconnect to newer Samba servers (or other servers
  21. which support the CIFS Unix/POSIX extensions) so that we again tell the
  22. server the Unix/POSIX cifs capabilities which we support (SetFSInfo).
  23. Add experimental support for new POSIX Open/Mkdir (which returns
  24. stat information on the open, and allows setting the mode).
  25. Version 1.46
  26. ------------
  27. Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
  28. Allow null user to be specified on mount ("username="). Do not return
  29. EINVAL on readdir when filldir fails due to overwritten blocksize
  30. (fixes FC problem). Return error in rename 2nd attempt retry (ie report
  31. if rename by handle also fails, after rename by path fails, we were
  32. not reporting whether the retry worked or not). Fix NTLMv2 to
  33. work to Windows servers (mount with option "sec=ntlmv2").
  34. Version 1.45
  35. ------------
  36. Do not time out lockw calls when using posix extensions. Do not
  37. time out requests if server still responding reasonably fast
  38. on requests on other threads. Improve POSIX locking emulation,
  39. (lock cancel now works, and unlock of merged range works even
  40. to Windows servers now). Fix oops on mount to lanman servers
  41. (win9x, os/2 etc.) when null password. Do not send listxattr
  42. (SMB to query all EAs) if nouser_xattr specified. Fix SE Linux
  43. problem (instantiate inodes/dentries in right order for readdir).
  44. Version 1.44
  45. ------------
  46. Rewritten sessionsetup support, including support for legacy SMB
  47. session setup needed for OS/2 and older servers such as Windows 95 and 98.
  48. Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst
  49. so we can do search (ls etc.) to OS/2. Do not send NTCreateX
  50. or recent levels of FindFirst unless server says it supports NT SMBs
  51. (instead use legacy equivalents from LANMAN dialect). Fix to allow
  52. NTLMv2 authentication support (now can use stronger password hashing
  53. on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004).
  54. Allow override of global cifs security flags on mount via "sec=" option(s).
  55. Version 1.43
  56. ------------
  57. POSIX locking to servers which support CIFS POSIX Extensions
  58. (disabled by default controlled by proc/fs/cifs/Experimental).
  59. Handle conversion of long share names (especially Asian languages)
  60. to Unicode during mount. Fix memory leak in sess struct on reconnect.
  61. Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
  62. cifs open which helps rare case when setpathinfo fails or server does
  63. not support it.
  64. Version 1.42
  65. ------------
  66. Fix slow oplock break when mounted to different servers at the same time and
  67. the tids match and we try to find matching fid on wrong server. Fix read
  68. looping when signing required by server (2.6.16 kernel only). Fix readdir
  69. vs. rename race which could cause each to hang. Return . and .. even
  70. if server does not. Allow searches to skip first three entries and
  71. begin at any location. Fix oops in find_writeable_file.
  72. Version 1.41
  73. ------------
  74. Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
  75. configure stronger authentication. Fix sfu symlinks so they can
  76. be followed (not just recognized). Fix wraparound of bcc on
  77. read responses when buffer size over 64K and also fix wrap of
  78. max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
  79. cifs_user_read and cifs_readpages (when EAGAIN on send of smb
  80. on socket is returned over and over). Add POSIX (advisory) byte range
  81. locking support (requires server with newest CIFS UNIX Extensions
  82. to the protocol implemented). Slow down negprot slightly in port 139
  83. RFC1001 case to give session_init time on buggy servers.
  84. Version 1.40
  85. ------------
  86. Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
  87. of readpages by eliminating one extra memcpy. Allow update of file size
  88. from remote server even if file is open for write as long as mount is
  89. directio. Recognize share mode security and send NTLM encrypted password
  90. on tree connect if share mode negotiated.
  91. Version 1.39
  92. ------------
  93. Defer close of a file handle slightly if pending writes depend on that handle
  94. (this reduces the EBADF bad file handle errors that can be logged under heavy
  95. stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
  96. Fix SFU style symlinks and mknod needed for servers which do not support the
  97. CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
  98. dentries so files that the client sees as deleted but that later get created
  99. on the server will be recognized. Add client side permission check on setattr.
  100. Timeout stuck requests better (where server has never responded or sent corrupt
  101. responses)
  102. Version 1.38
  103. ------------
  104. Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
  105. to be smaller at first (but increasing) so large write performance performance
  106. over GigE is better. Do not hang thread on illegal byte range lock response
  107. from Windows (Windows can send an RFC1001 size which does not match smb size) by
  108. allowing an SMBs TCP length to be up to a few bytes longer than it should be.
  109. wsize and rsize can now be larger than negotiated buffer size if server
  110. supports large readx/writex, even when directio mount flag not specified.
  111. Write size will in many cases now be 16K instead of 4K which greatly helps
  112. file copy performance on lightly loaded networks. Fix oops in dnotify
  113. when experimental config flag enabled. Make cifsFYI more granular.
  114. Version 1.37
  115. ------------
  116. Fix readdir caching when unlink removes file in current search buffer,
  117. and this is followed by a rewind search to just before the deleted entry.
  118. Do not attempt to set ctime unless atime and/or mtime change requested
  119. (most servers throw it away anyway). Fix length check of received smbs
  120. to be more accurate. Fix big endian problem with mapchars mount option,
  121. and with a field returned by statfs.
  122. Version 1.36
  123. ------------
  124. Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
  125. For these older servers, add option for passing netbios name of server in
  126. on mount (servernetbiosname). Add suspend support for power management, to
  127. avoid cifsd thread preventing software suspend from working.
  128. Add mount option for disabling the default behavior of sending byte range lock
  129. requests to the server (necessary for certain applications which break with
  130. mandatory lock behavior such as Evolution), and also mount option for
  131. requesting case insensitive matching for path based requests (requesting
  132. case sensitive is the default).
  133. Version 1.35
  134. ------------
  135. Add writepage performance improvements. Fix path name conversions
  136. for long filenames on mounts which were done with "mapchars" mount option
  137. specified. Ensure multiplex ids do not collide. Fix case in which
  138. rmmod can oops if done soon after last unmount. Fix truncated
  139. search (readdir) output when resume filename was a long filename.
  140. Fix filename conversion when mapchars mount option was specified and
  141. filename was a long filename.
  142. Version 1.34
  143. ------------
  144. Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
  145. Do not oops if root user kills cifs oplock kernel thread or
  146. kills the cifsd thread (NB: killing the cifs kernel threads is not
  147. recommended, unmount and rmmod cifs will kill them when they are
  148. no longer needed). Fix readdir to ASCII servers (ie older servers
  149. which do not support Unicode) and also require asterisk.
  150. Fix out of memory case in which data could be written one page
  151. off in the page cache.
  152. Version 1.33
  153. ------------
  154. Fix caching problem, in which readdir of directory containing a file
  155. which was cached could cause the file's time stamp to be updated
  156. without invalidating the readahead data (so we could get stale
  157. file data on the client for that file even as the server copy changed).
  158. Cleanup response processing so cifsd can not loop when abnormally
  159. terminated.
  160. Version 1.32
  161. ------------
  162. Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
  163. transact response for an SMB request and search entry split across two frames.
  164. Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
  165. as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
  166. unless server explicitly claims to support them in CIFS Unix extensions
  167. POSIX ACL capability bit. Fix packet signing when multiuser mounting with
  168. different users from the same client to the same server. Fix oops in
  169. cifs_close. Add mount option for remapping reserved characters in
  170. filenames (also allow recognizing files with created by SFU which have any
  171. of these seven reserved characters, except backslash, to be recognized).
  172. Fix invalid transact2 message (we were sometimes trying to interpret
  173. oplock breaks as SMB responses). Add ioctl for checking that the
  174. current uid matches the uid of the mounter (needed by umount.cifs).
  175. Reduce the number of large buffer allocations in cifs response processing
  176. (significantly reduces memory pressure under heavy stress with multiple
  177. processes accessing the same server at the same time).
  178. Version 1.31
  179. ------------
  180. Fix updates of DOS attributes and time fields so that files on NT4 servers
  181. do not get marked delete on close. Display sizes of cifs buffer pools in
  182. cifs stats. Fix oops in unmount when cifsd thread being killed by
  183. shutdown. Add generic readv/writev and aio support. Report inode numbers
  184. consistently in readdir and lookup (when serverino mount option is
  185. specified use the inode number that the server reports - for both lookup
  186. and readdir, otherwise by default the locally generated inode number is used
  187. for inodes created in either path since servers are not always able to
  188. provide unique inode numbers when exporting multiple volumes from under one
  189. sharename).
  190. Version 1.30
  191. ------------
  192. Allow new nouser_xattr mount parm to disable xattr support for user namespace.
  193. Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
  194. (mostly affects NT4 servers) by retry with handle based network operation.
  195. Add new POSIX Query FS Info for returning statfs info more accurately.
  196. Handle passwords with multiple commas in them.
  197. Version 1.29
  198. ------------
  199. Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
  200. Fix capabilities flags for large readx so as to allow reads larger than 64K.
  201. Version 1.28
  202. ------------
  203. Add module init parm for large SMB buffer size (to allow it to be changed
  204. from its default of 16K) which is especially useful for large file copy
  205. when mounting with the directio mount option. Fix oops after
  206. returning from mount when experimental ExtendedSecurity enabled and
  207. SpnegoNegotiated returning invalid error. Fix case to retry better when
  208. peek returns from 1 to 3 bytes on socket which should have more data.
  209. Fixed path based calls (such as cifs lookup) to handle path names
  210. longer than 530 (now can handle PATH_MAX). Fix pass through authentication
  211. from Samba server to DC (Samba required dummy LM password).
  212. Version 1.27
  213. ------------
  214. Turn off DNOTIFY (directory change notification support) by default
  215. (unless built with the experimental flag) to fix hang with KDE
  216. file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
  217. waiting on an SMB response) in SendReceive when session dies but
  218. reconnects quickly from another task. Add module init parms for
  219. minimum number of large and small network buffers in the buffer pools,
  220. and for the maximum number of simultaneous requests.
  221. Version 1.26
  222. ------------
  223. Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
  224. and other POSIX CIFS compliant servers. Fix error mapping for getfacl
  225. to EOPNOTSUPP when server does not support posix acls on the wire. Fix
  226. improperly zeroed buffer in CIFS Unix extensions set times call.
  227. Version 1.25
  228. ------------
  229. Fix internationalization problem in cifs readdir with filenames that map to
  230. longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
  231. for readdir to netapp servers. Fix search rewind (seek into readdir to return
  232. non-consecutive entries). Do not do readdir when server negotiates
  233. buffer size to small to fit filename. Add support for reading POSIX ACLs from
  234. the server (add also acl and noacl mount options).
  235. Version 1.24
  236. ------------
  237. Optionally allow using server side inode numbers, rather than client generated
  238. ones by specifying mount option "serverino" - this is required for some apps
  239. to work which double check hardlinked files and have persistent inode numbers.
  240. Version 1.23
  241. ------------
  242. Multiple bigendian fixes. On little endian systems (for reconnect after
  243. network failure) fix tcp session reconnect code so we do not try first
  244. to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
  245. as directories rather than symlinks because we can do follow link on them.
  246. Version 1.22
  247. ------------
  248. Add config option to enable XATTR (extended attribute) support, mapping
  249. xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
  250. minor fixes pointed out by the Stanford SWAT checker (mostly missing
  251. or out of order NULL pointer checks in little used error paths).
  252. Version 1.21
  253. ------------
  254. Add new mount parm to control whether mode check (generic_permission) is done
  255. on the client. If Unix extensions are enabled and the uids on the client
  256. and server do not match, client permission checks are meaningless on
  257. server uids that do not exist on the client (this does not affect the
  258. normal ACL check which occurs on the server). Fix default uid
  259. on mknod to match create and mkdir. Add optional mount parm to allow
  260. override of the default uid behavior (in which the server sets the uid
  261. and gid of newly created files). Normally for network filesystem mounts
  262. user want the server to set the uid/gid on newly created files (rather than
  263. using uid of the client processes you would in a local filesystem).
  264. Version 1.20
  265. ------------
  266. Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
  267. info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
  268. (in build_wildcard_path_from_dentry). Fix mknod to pass type field
  269. (block/char/fifo) properly. Remove spurious mount warning log entry when
  270. credentials passed as mount argument. Set major/minor device number in
  271. inode for block and char devices when unix extensions enabled.
  272. Version 1.19
  273. ------------
  274. Fix /proc/fs/cifs/Stats and DebugData display to handle larger
  275. amounts of return data. Properly limit requests to MAX_REQ (50
  276. is the usual maximum active multiplex SMB/CIFS requests per server).
  277. Do not kill cifsd (and thus hurt the other SMB session) when more than one
  278. session to the same server (but with different userids) exists and one
  279. of the two user's smb sessions is being removed while leaving the other.
  280. Do not loop reconnecting in cifsd demultiplex thread when admin
  281. kills the thread without going through unmount.
  282. Version 1.18
  283. ------------
  284. Do not rename hardlinked files (since that should be a noop). Flush
  285. cached write behind data when reopening a file after session abend,
  286. except when already in write. Grab per socket sem during reconnect
  287. to avoid oops in sendmsg if overlapping with reconnect. Do not

  341. inode metadata can be incorrectly kept cached when time near zero)
  342. Version 1.08
  343. ------------
  344. Allow file_mode and dir_mode (specified at mount time) to be enforced

  372. filldir returns error during large directory searches (readdir).
  373. Version 1.02
  374. ------------
  375. Fix caching problem when files opened by multiple clients in which
  376. page cache could contain stale data, and write through did
  377. not occur often enough while file was still open when read ahead
  378. (read oplock) not allowed. Treat "sep=" when first mount option
  379. as an override of comma as the default separator between mount
  380. options.

  389. Version 0.99
  390. ------------
  391. Invalidate local inode cached pages on oplock break and when last file
  392. instance is closed so that the client does not continue using stale local
  393. copy rather than later modified server copy of file. Do not reconnect
  394. when server drops the tcp session prematurely before negotiate
  395. protocol response. Fix oops in reopen_file when dentry freed. Allow
  396. the support for CIFS Unix Extensions to be disabled via proc interface.

  469. ------------
  470. Fix oops when mounting to long server names caused by inverted parms to kmalloc.
  471. Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
  472. we will choose a cifs user session (smb uid) that better matches the local

  549. ------------
  550. Fix search handle leak on rewind. Fix setuid and gid so that they are
  551. reflected in the local inode immediately. Cleanup of whitespace
  552. to make 2.4 and 2.5 versions more consistent.
  553. Version 0.67
  554. ------------
  555. Fix signal sending so that captive thread (cifsd) exits on umount
  556. (which was causing the warning in kmem_cache_free of the request buffers
  557. at rmmod time). This had broken as a sideeffect of the recent global
  558. kernel change to daemonize. Fix memory leak in readdir code which
  559. showed up in "ls -R" (and applications that did search rewinding).
  560. Version 0.66

  577. ------------
  578. Fix memory leak in AllocMidQEntry.
  579. Finish reconnection logic, so connection with server can be dropped
  580. (or server rebooted) and the cifs client will reconnect.
  581. Version 0.62
  582. ------------
  583. Fix temporary socket leak when bad userid or password specified

  588. ------------
  589. Fix oops when username not passed in on mount. Extensive fixes and improvements
  590. to error logging (strip redundant newlines, change debug macros to ensure newline
  591. passed in and to be more consistent). Fix writepage wrong file handle problem,
  592. a readonly file handle could be incorrectly used to attempt to write out
  593. file updates through the page cache to multiply open files. This could cause
  594. the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
  595. shares to the same Windows server when using different usernames
  596. (doing this to Samba servers worked but Windows was rejecting it) - now it is

  598. Linux client. Fix oops when treeDisconnect called during unmount on
  599. previously freed socket.

  714. ------------
  715. 1) Fixed lockrange to be correct (it was one byte too short)
  716. 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
  717. show range as locked when there is a conflict with an existing lock.
  718. 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
  719. in most cases. Eventually will offer optional ability to query server for the correct perms.
  720. 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
  721. but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
  722. session)
  723. 4) Fixed error logging of valid mount options
  724. 5) Removed logging of password field.
  725. 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
  726. and cleaned them up and made them more consistent with other cifs functions.
  727. 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
  728. (with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
  729. nor is the symlink support using the Unix extensions
  730. 8) Started adding the readlink and follow_link code
  731. Version 0.3
