  1. Version 1.38
  2. ------------
  3. Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
  4. to be smaller at first (but increasing) so large write performance performance
  5. over GigE is better. Do not hang thread on illegal byte range lock response
  6. from Windows (Windows can send an RFC1001 size which does not match smb size) by
  7. allowing an SMBs TCP length to be up to a few bytes longer than it should be.
  8. wsize and rsize can now be larger than negotiated buffer size if server
  9. supports large readx/writex, even when directio mount flag not specified.
  10. Write size will in many cases now be 16K instead of 4K which greatly helps
  11. file copy performance on lightly loaded networks.
  12. Version 1.37
  13. ------------
  14. Fix readdir caching when unlink removes file in current search buffer,
  15. and this is followed by a rewind search to just before the deleted entry.
  16. Do not attempt to set ctime unless atime and/or mtime change requested
  17. (most servers throw it away anyway). Fix length check of received smbs
  18. to be more accurate. Fix big endian problem with mapchars mount option,
  19. and with a field returned by statfs.
  20. Version 1.36
  21. ------------
  22. Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
  23. For these older servers, add option for passing netbios name of server in
  24. on mount (servernetbiosname). Add suspend support for power management, to
  25. avoid cifsd thread preventing software suspend from working.
  26. Add mount option for disabling the default behavior of sending byte range lock
  27. requests to the server (necessary for certain applications which break with
  28. mandatory lock behavior such as Evolution), and also mount option for
  29. requesting case insensitive matching for path based requests (requesting
  30. case sensitive is the default).
  31. Version 1.35
  32. ------------
  33. Add writepage performance improvements. Fix path name conversions
  34. for long filenames on mounts which were done with "mapchars" mount option
  35. specified. Ensure multiplex ids do not collide. Fix case in which
  36. rmmod can oops if done soon after last unmount. Fix truncated
  37. search (readdir) output when resume filename was a long filename.
  38. Fix filename conversion when mapchars mount option was specified and
  39. filename was a long filename.
  40. Version 1.34
  41. ------------
  42. Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
  43. Do not oops if root user kills cifs oplock kernel thread or
  44. kills the cifsd thread (NB: killing the cifs kernel threads is not
  45. recommended, unmount and rmmod cifs will kill them when they are
  46. no longer needed). Fix readdir to ASCII servers (ie older servers
  47. which do not support Unicode) and also require asterisk.
  48. Fix out of memory case in which data could be written one page
  49. off in the page cache.
  50. Version 1.33
  51. ------------
  52. Fix caching problem, in which readdir of directory containing a file
  53. which was cached could cause the file's time stamp to be updated
  54. without invalidating the readahead data (so we could get stale
  55. file data on the client for that file even as the server copy changed).
  56. Cleanup response processing so cifsd can not loop when abnormally
  57. terminated.
  58. Version 1.32
  59. ------------
  60. Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
  61. transact response for an SMB request and search entry split across two frames.
  62. Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
  63. as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
  64. unless server explicitly claims to support them in CIFS Unix extensions
  65. POSIX ACL capability bit. Fix packet signing when multiuser mounting with
  66. different users from the same client to the same server. Fix oops in
  67. cifs_close. Add mount option for remapping reserved characters in
  68. filenames (also allow recognizing files with created by SFU which have any
  69. of these seven reserved characters, except backslash, to be recognized).
  70. Fix invalid transact2 message (we were sometimes trying to interpret
  71. oplock breaks as SMB responses). Add ioctl for checking that the
  72. current uid matches the uid of the mounter (needed by umount.cifs).
  73. Reduce the number of large buffer allocations in cifs response processing
  74. (significantly reduces memory pressure under heavy stress with multiple
  75. processes accessing the same server at the same time).
  76. Version 1.31
  77. ------------
  78. Fix updates of DOS attributes and time fields so that files on NT4 servers
  79. do not get marked delete on close. Display sizes of cifs buffer pools in
  80. cifs stats. Fix oops in unmount when cifsd thread being killed by
  81. shutdown. Add generic readv/writev and aio support. Report inode numbers
  82. consistently in readdir and lookup (when serverino mount option is
  83. specified use the inode number that the server reports - for both lookup
  84. and readdir, otherwise by default the locally generated inode number is used
  85. for inodes created in either path since servers are not always able to
  86. provide unique inode numbers when exporting multiple volumes from under one
  87. sharename).
  88. Version 1.30
  89. ------------
  90. Allow new nouser_xattr mount parm to disable xattr support for user namespace.
  91. Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
  92. (mostly affects NT4 servers) by retry with handle based network operation.
  93. Add new POSIX Query FS Info for returning statfs info more accurately.
  94. Handle passwords with multiple commas in them.
  95. Version 1.29
  96. ------------
  97. Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
  98. Fix capabilities flags for large readx so as to allow reads larger than 64K.
  99. Version 1.28
  100. ------------
  101. Add module init parm for large SMB buffer size (to allow it to be changed
  102. from its default of 16K) which is especially useful for large file copy
  103. when mounting with the directio mount option. Fix oops after
  104. returning from mount when experimental ExtendedSecurity enabled and
  105. SpnegoNegotiated returning invalid error. Fix case to retry better when
  106. peek returns from 1 to 3 bytes on socket which should have more data.
  107. Fixed path based calls (such as cifs lookup) to handle path names
  108. longer than 530 (now can handle PATH_MAX). Fix pass through authentication
  109. from Samba server to DC (Samba required dummy LM password).
  110. Version 1.27
  111. ------------
  112. Turn off DNOTIFY (directory change notification support) by default
  113. (unless built with the experimental flag) to fix hang with KDE
  114. file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
  115. waiting on an SMB response) in SendReceive when session dies but
  116. reconnects quickly from another task. Add module init parms for
  117. minimum number of large and small network buffers in the buffer pools,
  118. and for the maximum number of simultaneous requests.
  119. Version 1.26
  120. ------------
  121. Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
  122. and other POSIX CIFS compliant servers. Fix error mapping for getfacl
  123. to EOPNOTSUPP when server does not support posix acls on the wire. Fix
  124. improperly zeroed buffer in CIFS Unix extensions set times call.
  125. Version 1.25
  126. ------------
  127. Fix internationalization problem in cifs readdir with filenames that map to
  128. longer UTF8 strings than the string on the wire was in Unicode. Add workaround
  129. for readdir to netapp servers. Fix search rewind (seek into readdir to return
  130. non-consecutive entries). Do not do readdir when server negotiates
  131. buffer size to small to fit filename. Add support for reading POSIX ACLs from
  132. the server (add also acl and noacl mount options).
  133. Version 1.24
  134. ------------
  135. Optionally allow using server side inode numbers, rather than client generated
  136. ones by specifying mount option "serverino" - this is required for some apps
  137. to work which double check hardlinked files and have persistent inode numbers.
  138. Version 1.23
  139. ------------
  140. Multiple bigendian fixes. On little endian systems (for reconnect after
  141. network failure) fix tcp session reconnect code so we do not try first
  142. to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
  143. as directories rather than symlinks because we can do follow link on them.
  144. Version 1.22
  145. ------------
  146. Add config option to enable XATTR (extended attribute) support, mapping
  147. xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
  148. minor fixes pointed out by the Stanford SWAT checker (mostly missing
  149. or out of order NULL pointer checks in little used error paths).
  150. Version 1.21
  151. ------------
  152. Add new mount parm to control whether mode check (generic_permission) is done
  153. on the client. If Unix extensions are enabled and the uids on the client
  154. and server do not match, client permission checks are meaningless on
  155. server uids that do not exist on the client (this does not affect the
  156. normal ACL check which occurs on the server). Fix default uid
  157. on mknod to match create and mkdir. Add optional mount parm to allow
  158. override of the default uid behavior (in which the server sets the uid
  159. and gid of newly created files). Normally for network filesystem mounts
  160. user want the server to set the uid/gid on newly created files (rather than
  161. using uid of the client processes you would in a local filesystem).
  162. Version 1.20
  163. ------------
  164. Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
  165. info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
  166. (in build_wildcard_path_from_dentry). Fix mknod to pass type field
  167. (block/char/fifo) properly. Remove spurious mount warning log entry when
  168. credentials passed as mount argument. Set major/minor device number in
  169. inode for block and char devices when unix extensions enabled.
  170. Version 1.19
  171. ------------
  172. Fix /proc/fs/cifs/Stats and DebugData display to handle larger
  173. amounts of return data. Properly limit requests to MAX_REQ (50
  174. is the usual maximum active multiplex SMB/CIFS requests per server).
  175. Do not kill cifsd (and thus hurt the other SMB session) when more than one
  176. session to the same server (but with different userids) exists and one
  177. of the two user's smb sessions is being removed while leaving the other.
  178. Do not loop reconnecting in cifsd demultiplex thread when admin
  179. kills the thread without going through unmount.
  180. Version 1.18
  181. ------------
  182. Do not rename hardlinked files (since that should be a noop). Flush
  183. cached write behind data when reopening a file after session abend,
  184. except when already in write. Grab per socket sem during reconnect
  185. to avoid oops in sendmsg if overlapping with reconnect. Do not
  186. reset cached inode file size on readdir for files open for write on
  187. client.
  188. Version 1.17
  189. ------------
  190. Update number of blocks in file so du command is happier (in Linux a fake
  191. blocksize of 512 is required for calculating number of blocks in inode).
  192. Fix prepare write of partial pages to read in data from server if possible.
  193. Fix race on tcpStatus field between unmount and reconnection code, causing
  194. cifsd process sometimes to hang around forever. Improve out of memory
  195. checks in cifs_filldir
  196. Version 1.16
  197. ------------
  198. Fix incorrect file size in file handle based setattr on big endian hardware.
  199. Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
  200. and closing file structs in writepage/partialpagewrite. Add statistics
  201. for each mounted share (new menuconfig option). Fix endianness problem in
  202. volume information displayed in /proc/fs/cifs/DebugData (only affects
  203. affects big endian architectures). Prevent renames while constructing
  204. path names for open, mkdir and rmdir.
  205. Version 1.15
  206. ------------
  207. Change to mempools for alloc smb request buffers and multiplex structs
  208. to better handle low memory problems (and potential deadlocks).
  209. Version 1.14
  210. ------------
  211. Fix incomplete listings of large directories on Samba servers when Unix
  212. extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
  213. rename deadlock when writing out dirty pages at same time.
  214. Version 1.13
  215. ------------
  216. Fix open of files in which O_CREATE can cause the mode to change in
  217. some cases. Fix case in which retry of write overlaps file close.
  218. Fix PPC64 build error. Reduce excessive stack usage in smb password
  219. hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
  220. Version 1.12
  221. ------------
  222. Fixes for large file copy, signal handling, socket retry, buffer
  223. allocation and low memory situations.
  224. Version 1.11
  225. ------------
  226. Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
  227. also now allowing support for specifying client netbiosname. NT4 support added.
  228. Version 1.10
  229. ------------
  230. Fix reconnection (and certain failed mounts) to properly wake up the
  231. blocked users thread so it does not seem hung (in some cases was blocked
  232. until the cifs receive timeout expired). Fix spurious error logging
  233. to kernel log when application with open network files killed.
  234. Version 1.09
  235. ------------
  236. Fix /proc/fs module unload warning message (that could be logged
  237. to the kernel log). Fix intermittent failure in connectathon
  238. test7 (hardlink count not immediately refreshed in case in which
  239. inode metadata can be incorrectly kept cached when time near zero)
  240. Version 1.08
  241. ------------
  242. Allow file_mode and dir_mode (specified at mount time) to be enforced
  243. locally (the server already enforced its own ACLs too) for servers
  244. that do not report the correct mode (do not support the
  245. CIFS Unix Extensions).
  246. Version 1.07
  247. ------------
  248. Fix some small memory leaks in some unmount error paths. Fix major leak
  249. of cache pages in readpages causing multiple read oriented stress
  250. testcases (including fsx, and even large file copy) to fail over time.
  251. Version 1.06
  252. ------------
  253. Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
  254. This allows files that differ only in case and improves performance of file
  255. creation and file open to such servers. Fix semaphore conflict which causes
  256. slow delete of open file to Samba (which unfortunately can cause an oplock
  257. break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
  258. Version 1.05
  259. ------------
  260. fixes to cifs_readpages for fsx test case
  261. Version 1.04
  262. ------------
  263. Fix caching data integrity bug when extending file size especially when no
  264. oplock on file. Fix spurious logging of valid already parsed mount options
  265. that are parsed outside of the cifs vfs such as nosuid.
  266. Version 1.03
  267. ------------
  268. Connect to server when port number override not specified, and tcp port
  269. unitialized. Reset search to restart at correct file when kernel routine
  270. filldir returns error during large directory searches (readdir).
  271. Version 1.02
  272. ------------
  273. Fix caching problem when files opened by multiple clients in which
  274. page cache could contain stale data, and write through did
  275. not occur often enough while file was still open when read ahead
  276. (read oplock) not allowed. Treat "sep=" when first mount option
  277. as an override of comma as the default separator between mount
  278. options.
  279. Version 1.01
  280. ------------
  281. Allow passwords longer than 16 bytes. Allow null password string.
  282. Version 1.00
  283. ------------
  284. Gracefully clean up failed mounts when attempting to mount to servers such as
  285. Windows 98 that terminate tcp sessions during protocol negotiation. Handle
  286. embedded commas in mount parsing of passwords.
  287. Version 0.99
  288. ------------
  289. Invalidate local inode cached pages on oplock break and when last file
  290. instance is closed so that the client does not continue using stale local
  291. copy rather than later modified server copy of file. Do not reconnect
  292. when server drops the tcp session prematurely before negotiate
  293. protocol response. Fix oops in reopen_file when dentry freed. Allow
  294. the support for CIFS Unix Extensions to be disabled via proc interface.
  295. Version 0.98
  296. ------------
  297. Fix hang in commit_write during reconnection of open files under heavy load.
  298. Fix unload_nls oops in a mount failure path. Serialize writes to same socket
  299. which also fixes any possible races when cifs signatures are enabled in SMBs
  300. being sent out of signature sequence number order.
  301. Version 0.97
  302. ------------
  303. Fix byte range locking bug (endian problem) causing bad offset and
  304. length.
  305. Version 0.96
  306. ------------
  307. Fix oops (in send_sig) caused by CIFS unmount code trying to
  308. wake up the demultiplex thread after it had exited. Do not log
  309. error on harmless oplock release of closed handle.
  310. Version 0.95
  311. ------------
  312. Fix unsafe global variable usage and password hash failure on gcc 3.3.1
  313. Fix problem reconnecting secondary mounts to same server after session
  314. failure. Fix invalid dentry - race in mkdir when directory gets created
  315. by another client between the lookup and mkdir.
  316. Version 0.94
  317. ------------
  318. Fix to list processing in reopen_files. Fix reconnection when server hung
  319. but tcpip session still alive. Set proper timeout on socket read.
  320. Version 0.93
  321. ------------
  322. Add missing mount options including iocharset. SMP fixes in write and open.
  323. Fix errors in reconnecting after TCP session failure. Fix module unloading

  367. ------------
  368. Fix oops when mounting to long server names caused by inverted parms to kmalloc.
  369. Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
  370. we will choose a cifs user session (smb uid) that better matches the local

  451. Version 0.67
  452. ------------
  453. Fix signal sending so that captive thread (cifsd) exits on umount
  454. (which was causing the warning in kmem_cache_free of the request buffers
  455. at rmmod time). This had broken as a sideeffect of the recent global
  456. kernel change to daemonize. Fix memory leak in readdir code which
  457. showed up in "ls -R" (and applications that did search rewinding).

  475. ------------
  476. Fix memory leak in AllocMidQEntry.
  477. Finish reconnection logic, so connection with server can be dropped
  478. (or server rebooted) and the cifs client will reconnect.
  479. Version 0.62
  480. ------------
  481. Fix temporary socket leak when bad userid or password specified
  482. (or other SMBSessSetup failure). Increase maximum buffer size to slightly

  484. sizes. Add support for readpages
  485. Version 0.61
  486. ------------
  487. Fix oops when username not passed in on mount. Extensive fixes and improvements
  488. to error logging (strip redundant newlines, change debug macros to ensure newline
  489. passed in and to be more consistent). Fix writepage wrong file handle problem,
  490. a readonly file handle could be incorrectly used to attempt to write out
  491. file updates through the page cache to multiply open files. This could cause
  492. the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
  493. shares to the same Windows server when using different usernames
  494. (doing this to Samba servers worked but Windows was rejecting it) - now it is
  495. possible to use different userids when connecting to the same server from a
  496. Linux client. Fix oops when treeDisconnect called during unmount on
  497. previously freed socket.

  612. ------------
  613. 1) Fixed lockrange to be correct (it was one byte too short)
  614. 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
  615. show range as locked when there is a conflict with an existing lock.
  616. 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
  617. in most cases. Eventually will offer optional ability to query server for the correct perms.
  618. 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
  619. but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
  620. session)
  621. 4) Fixed error logging of valid mount options
  622. 5) Removed logging of password field.
  623. 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
  624. and cleaned them up and made them more consistent with other cifs functions.
  625. 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
  626. (with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
  627. nor is the symlink support using the Unix extensions
  628. 8) Started adding the readlink and follow_link code
