  1. Version 1.39
  2. ------------
  3. Defer close of a file handle slightly if pending writes depend on that file handle
  4. (this reduces the EBADF bad file handle errors that can be logged under heavy
  5. stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
  6. Version 1.38
  7. ------------
  8. Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
  9. to be smaller at first (but increasing) so large write performance performance
  10. over GigE is better. Do not hang thread on illegal byte range lock response
  11. from Windows (Windows can send an RFC1001 size which does not match smb size) by
  12. allowing an SMBs TCP length to be up to a few bytes longer than it should be.
  13. wsize and rsize can now be larger than negotiated buffer size if server
  14. supports large readx/writex, even when directio mount flag not specified.
  15. Write size will in many cases now be 16K instead of 4K which greatly helps
  16. file copy performance on lightly loaded networks. Fix oops in dnotify
  17. when experimental config flag enabled. Make cifsFYI more granular.
  18. Version 1.37
  19. ------------
  20. Fix readdir caching when unlink removes file in current search buffer,
  21. and this is followed by a rewind search to just before the deleted entry.
  22. Do not attempt to set ctime unless atime and/or mtime change requested
  23. (most servers throw it away anyway). Fix length check of received smbs
  24. to be more accurate. Fix big endian problem with mapchars mount option,
  25. and with a field returned by statfs.
  26. Version 1.36
  27. ------------
  28. Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
  29. For these older servers, add option for passing netbios name of server in
  30. on mount (servernetbiosname). Add suspend support for power management, to
  31. avoid cifsd thread preventing software suspend from working.
  32. Add mount option for disabling the default behavior of sending byte range lock
  33. requests to the server (necessary for certain applications which break with
  34. mandatory lock behavior such as Evolution), and also mount option for
  35. requesting case insensitive matching for path based requests (requesting
  36. case sensitive is the default).
  37. Version 1.35
  38. ------------
  39. Add writepage performance improvements. Fix path name conversions
  40. for long filenames on mounts which were done with "mapchars" mount option
  41. specified. Ensure multiplex ids do not collide. Fix case in which
  42. rmmod can oops if done soon after last unmount. Fix truncated
  43. search (readdir) output when resume filename was a long filename.
  44. Fix filename conversion when mapchars mount option was specified and
  45. filename was a long filename.
  46. Version 1.34
  47. ------------
  48. Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
  49. Do not oops if root user kills cifs oplock kernel thread or
  50. kills the cifsd thread (NB: killing the cifs kernel threads is not
  51. recommended, unmount and rmmod cifs will kill them when they are
  52. no longer needed). Fix readdir to ASCII servers (ie older servers
  53. which do not support Unicode) and also require asterisk.
  54. Fix out of memory case in which data could be written one page
  55. off in the page cache.
  56. Version 1.33
  57. ------------
  58. Fix caching problem, in which readdir of directory containing a file
  59. which was cached could cause the file's time stamp to be updated
  60. without invalidating the readahead data (so we could get stale
  61. file data on the client for that file even as the server copy changed).
  62. Cleanup response processing so cifsd can not loop when abnormally
  63. terminated.
  64. Version 1.32
  65. ------------
  66. Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
  67. transact response for an SMB request and search entry split across two frames.
  68. Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
  69. as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
  70. unless server explicitly claims to support them in CIFS Unix extensions
  71. POSIX ACL capability bit. Fix packet signing when multiuser mounting with
  72. different users from the same client to the same server. Fix oops in
  73. cifs_close. Add mount option for remapping reserved characters in
  74. filenames (also allow recognizing files with created by SFU which have any
  75. of these seven reserved characters, except backslash, to be recognized).
  76. Fix invalid transact2 message (we were sometimes trying to interpret
  77. oplock breaks as SMB responses). Add ioctl for checking that the
  78. current uid matches the uid of the mounter (needed by umount.cifs).
  79. Reduce the number of large buffer allocations in cifs response processing
  80. (significantly reduces memory pressure under heavy stress with multiple
  81. processes accessing the same server at the same time).
  82. Version 1.31
  83. ------------
  84. Fix updates of DOS attributes and time fields so that files on NT4 servers
  85. do not get marked delete on close. Display sizes of cifs buffer pools in
  86. cifs stats. Fix oops in unmount when cifsd thread being killed by
  87. shutdown. Add generic readv/writev and aio support. Report inode numbers
  88. consistently in readdir and lookup (when serverino mount option is
  89. specified use the inode number that the server reports - for both lookup
  90. and readdir, otherwise by default the locally generated inode number is used
  91. for inodes created in either path since servers are not always able to
  92. provide unique inode numbers when exporting multiple volumes from under one
  93. sharename).
  94. Version 1.30
  95. ------------
  96. Allow new nouser_xattr mount parm to disable xattr support for user namespace.
  97. Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
  98. (mostly affects NT4 servers) by retry with handle based network operation.
  99. Add new POSIX Query FS Info for returning statfs info more accurately.
  100. Handle passwords with multiple commas in them.
  101. Version 1.29
  102. ------------
  103. Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
  104. Fix capabilities flags for large readx so as to allow reads larger than 64K.
  105. Version 1.28
  106. ------------
  107. Add module init parm for large SMB buffer size (to allow it to be changed
  108. from its default of 16K) which is especially useful for large file copy
  109. when mounting with the directio mount option. Fix oops after
  110. returning from mount when experimental ExtendedSecurity enabled and
  111. SpnegoNegotiated returning invalid error. Fix case to retry better when
  112. peek returns from 1 to 3 bytes on socket which should have more data.
  113. Fixed path based calls (such as cifs lookup) to handle path names
  114. longer than 530 (now can handle PATH_MAX). Fix pass through authentication
  115. from Samba server to DC (Samba required dummy LM password).
  116. Version 1.27
  117. ------------
  118. Turn off DNOTIFY (directory change notification support) by default
  119. (unless built with the experimental flag) to fix hang with KDE
  120. file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
  121. waiting on an SMB response) in SendReceive when session dies but
  122. reconnects quickly from another task. Add module init parms for
  123. minimum number of large and small network buffers in the buffer pools,
  124. and for the maximum number of simultaneous requests.
  125. Version 1.26
  126. ------------
  127. Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
  128. and other POSIX CIFS compliant servers. Fix error mapping for getfacl
  129. to EOPNOTSUPP when server does not support posix acls on the wire. Fix
  130. improperly zeroed buffer in CIFS Unix extensions set times call.
  131. Version 1.25
  132. ------------
  133. Fix internationalization problem in cifs readdir with filenames that map to
  134. longer UTF8 strings than the string on the wire was in Unicode. Add workaround
  135. for readdir to netapp servers. Fix search rewind (seek into readdir to return
  136. non-consecutive entries). Do not do readdir when server negotiates
  137. buffer size to small to fit filename. Add support for reading POSIX ACLs from
  138. the server (add also acl and noacl mount options).
  139. Version 1.24
  140. ------------
  141. Optionally allow using server side inode numbers, rather than client generated
  142. ones by specifying mount option "serverino" - this is required for some apps
  143. to work which double check hardlinked files and have persistent inode numbers.
  144. Version 1.23
  145. ------------
  146. Multiple bigendian fixes. On little endian systems (for reconnect after
  147. network failure) fix tcp session reconnect code so we do not try first
  148. to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
  149. as directories rather than symlinks because we can do follow link on them.
  150. Version 1.22
  151. ------------
  152. Add config option to enable XATTR (extended attribute) support, mapping
  153. xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
  154. minor fixes pointed out by the Stanford SWAT checker (mostly missing
  155. or out of order NULL pointer checks in little used error paths).
  156. Version 1.21
  157. ------------
  158. Add new mount parm to control whether mode check (generic_permission) is done
  159. on the client. If Unix extensions are enabled and the uids on the client
  160. and server do not match, client permission checks are meaningless on
  161. server uids that do not exist on the client (this does not affect the
  162. normal ACL check which occurs on the server). Fix default uid
  163. on mknod to match create and mkdir. Add optional mount parm to allow
  164. override of the default uid behavior (in which the server sets the uid
  165. and gid of newly created files). Normally for network filesystem mounts
  166. user want the server to set the uid/gid on newly created files (rather than
  167. using uid of the client processes you would in a local filesystem).
  168. Version 1.20
  169. ------------
  170. Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
  171. info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
  172. (in build_wildcard_path_from_dentry). Fix mknod to pass type field
  173. (block/char/fifo) properly. Remove spurious mount warning log entry when
  174. credentials passed as mount argument. Set major/minor device number in
  175. inode for block and char devices when unix extensions enabled.
  176. Version 1.19
  177. ------------
  178. Fix /proc/fs/cifs/Stats and DebugData display to handle larger
  179. amounts of return data. Properly limit requests to MAX_REQ (50
  180. is the usual maximum active multiplex SMB/CIFS requests per server).
  181. Do not kill cifsd (and thus hurt the other SMB session) when more than one
  182. session to the same server (but with different userids) exists and one
  183. of the two user's smb sessions is being removed while leaving the other.
  184. Do not loop reconnecting in cifsd demultiplex thread when admin
  185. kills the thread without going through unmount.
  186. Version 1.18
  187. ------------
  188. Do not rename hardlinked files (since that should be a noop). Flush
  189. cached write behind data when reopening a file after session abend,
  190. except when already in write. Grab per socket sem during reconnect
  191. to avoid oops in sendmsg if overlapping with reconnect. Do not
  192. reset cached inode file size on readdir for files open for write on
  193. client.
  194. Version 1.17
  195. ------------
  196. Update number of blocks in file so du command is happier (in Linux a fake
  197. blocksize of 512 is required for calculating number of blocks in inode).
  198. Fix prepare write of partial pages to read in data from server if possible.
  199. Fix race on tcpStatus field between unmount and reconnection code, causing
  200. cifsd process sometimes to hang around forever. Improve out of memory
  201. checks in cifs_filldir
  202. Version 1.16
  203. ------------
  204. Fix incorrect file size in file handle based setattr on big endian hardware.
  205. Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
  206. and closing file structs in writepage/partialpagewrite. Add statistics
  207. for each mounted share (new menuconfig option). Fix endianness problem in
  208. volume information displayed in /proc/fs/cifs/DebugData (only affects
  209. affects big endian architectures). Prevent renames while constructing
  210. path names for open, mkdir and rmdir.
  211. Version 1.15
  212. ------------
  213. Change to mempools for alloc smb request buffers and multiplex structs
  214. to better handle low memory problems (and potential deadlocks).
  215. Version 1.14
  216. ------------
  217. Fix incomplete listings of large directories on Samba servers when Unix
  218. extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
  219. rename deadlock when writing out dirty pages at same time.
  220. Version 1.13
  221. ------------
  222. Fix open of files in which O_CREATE can cause the mode to change in
  223. some cases. Fix case in which retry of write overlaps file close.
  224. Fix PPC64 build error. Reduce excessive stack usage in smb password
  225. hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
  226. Version 1.12
  227. ------------
  228. Fixes for large file copy, signal handling, socket retry, buffer
  229. allocation and low memory situations.
  230. Version 1.11
  231. ------------
  232. Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
  233. also now allowing support for specifying client netbiosname. NT4 support added.
  234. Version 1.10
  235. ------------
  236. Fix reconnection (and certain failed mounts) to properly wake up the
  237. blocked users thread so it does not seem hung (in some cases was blocked
  238. until the cifs receive timeout expired). Fix spurious error logging
  239. to kernel log when application with open network files killed.
  240. Version 1.09
  241. ------------
  242. Fix /proc/fs module unload warning message (that could be logged
  243. to the kernel log). Fix intermittent failure in connectathon
  244. test7 (hardlink count not immediately refreshed in case in which
  245. inode metadata can be incorrectly kept cached when time near zero)
  246. Version 1.08
  247. ------------
  248. Allow file_mode and dir_mode (specified at mount time) to be enforced
  249. locally (the server already enforced its own ACLs too) for servers
  250. that do not report the correct mode (do not support the
  251. CIFS Unix Extensions).
  252. Version 1.07
  253. ------------
  254. Fix some small memory leaks in some unmount error paths. Fix major leak
  255. of cache pages in readpages causing multiple read oriented stress
  256. testcases (including fsx, and even large file copy) to fail over time.
  257. Version 1.06
  258. ------------
  259. Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
  260. This allows files that differ only in case and improves performance of file
  261. creation and file open to such servers. Fix semaphore conflict which causes
  262. slow delete of open file to Samba (which unfortunately can cause an oplock
  263. break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
  264. Version 1.05
  265. ------------
  266. fixes to cifs_readpages for fsx test case
  267. Version 1.04
  268. ------------
  269. Fix caching data integrity bug when extending file size especially when no
  270. oplock on file. Fix spurious logging of valid already parsed mount options
  271. that are parsed outside of the cifs vfs such as nosuid.
  272. Version 1.03
  273. ------------
  274. Connect to server when port number override not specified, and tcp port
  275. unitialized. Reset search to restart at correct file when kernel routine
  276. filldir returns error during large directory searches (readdir).
  277. Version 1.02
  278. ------------
  279. Fix caching problem when files opened by multiple clients in which
  280. page cache could contain stale data, and write through did
  281. not occur often enough while file was still open when read ahead
  282. (read oplock) not allowed. Treat "sep=" when first mount option
  283. as an override of comma as the default separator between mount
  284. options.
  285. Version 1.01
  286. ------------
  287. Allow passwords longer than 16 bytes. Allow null password string.
  288. Version 1.00
  289. ------------
  290. Gracefully clean up failed mounts when attempting to mount to servers such as
  291. Windows 98 that terminate tcp sessions during protocol negotiation. Handle
  292. embedded commas in mount parsing of passwords.
  293. Version 0.99
  294. ------------
  295. Invalidate local inode cached pages on oplock break and when last file
  296. instance is closed so that the client does not continue using stale local
  297. copy rather than later modified server copy of file. Do not reconnect
  298. when server drops the tcp session prematurely before negotiate
  299. protocol response. Fix oops in reopen_file when dentry freed. Allow
  300. the support for CIFS Unix Extensions to be disabled via proc interface.
  301. Version 0.98
  302. ------------
  303. Fix hang in commit_write during reconnection of open files under heavy load.
  304. Fix unload_nls oops in a mount failure path. Serialize writes to same socket
  305. which also fixes any possible races when cifs signatures are enabled in SMBs
  306. being sent out of signature sequence number order.
  307. Version 0.97
  308. ------------
  309. Fix byte range locking bug (endian problem) causing bad offset and
  310. length.
  311. Version 0.96
  312. ------------
  313. Fix oops (in send_sig) caused by CIFS unmount code trying to
  314. wake up the demultiplex thread after it had exited. Do not log
  315. error on harmless oplock release of closed handle.
  316. Version 0.95
  317. ------------
  318. Fix unsafe global variable usage and password hash failure on gcc 3.3.1
  319. Fix problem reconnecting secondary mounts to same server after session
  320. failure. Fix invalid dentry - race in mkdir when directory gets created

  457. Version 0.67
  458. ------------
  459. Fix signal sending so that captive thread (cifsd) exits on umount
  460. (which was causing the warning in kmem_cache_free of the request buffers
  461. at rmmod time). This had broken as a sideeffect of the recent global
  462. kernel change to daemonize. Fix memory leak in readdir code which
  463. showed up in "ls -R" (and applications that did search rewinding).

  490. sizes. Add support for readpages
  491. Version 0.61
  492. ------------
  493. Fix oops when username not passed in on mount. Extensive fixes and improvements
  494. to error logging (strip redundant newlines, change debug macros to ensure newline
  495. passed in and to be more consistent). Fix writepage wrong file handle problem,
  496. a readonly file handle could be incorrectly used to attempt to write out
  497. file updates through the page cache to multiply open files. This could cause
  498. the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
  499. shares to the same Windows server when using different usernames
  500. (doing this to Samba servers worked but Windows was rejecting it) - now it is

  621. show range as locked when there is a conflict with an existing lock.
  622. 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
  623. in most cases. Eventually will offer optional ability to query server for the correct perms.
  624. 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
  625. but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
  626. session)
  627. 4) Fixed error logging of valid mount options
  628. 5) Removed logging of password field.
  629. 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
  630. and cleaned them up and made them more consistent with other cifs functions.
  631. 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
  632. (with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
  633. nor is the symlink support using the Unix extensions
  634. 8) Started adding the readlink and follow_link code
