1Version 1.49 2------------ 3IPv6 support. Enable ipv6 addresses to be passed on mount (put the ipv6 4address after the "ip=" mount option, at least until mount.cifs is fixed to 5handle DNS host to ipv6 name translation). Accept override of uid or gid 6on mount even when Unix Extensions are negotiated (it used to be ignored 7when Unix Extensions were ignored). This allows users to override the 8default uid and gid for files when they are certain that the uids or 9gids on the server do not match those of the client. Make "sec=none" 10mount override username (so that null user connection is attempted) 11to match what documentation said. 12 13Version 1.48 14------------ 15Fix mtime bouncing around from local idea of last write times to remote time. 16Fix hang (in i_size_read) when simultaneous size update of same remote file 17on smp system corrupts sequence number. Do not reread unnecessarily partial page 18(which we are about to overwrite anyway) when writing out file opened rw. 19When DOS attribute of file on non-Unix server's file changes on the server side 20from read-only back to read-write, reflect this change in default file mode 21(we had been leaving a file's mode read-only until the inode were reloaded). 22Allow setting of attribute back to ATTR_NORMAL (removing readonly dos attribute 23when archive dos attribute not set and we are changing mode back to writeable 24on server which does not support the Unix Extensions). Remove read only dos 25attribute on chmod when adding any write permission (ie on any of 26user/group/other (not all of user/group/other ie 0222) when 27mounted to windows. Add support for POSIX MkDir (slight performance 28enhancement and eliminates the network race between the mkdir and set 29path info of the mode). 30 31 32Version 1.47 33------------ 34Fix oops in list_del during mount caused by unaligned string. 35Fix file corruption which could occur on some large file 36copies caused by writepages page i/o completion bug. 37Seek to SEEK_END forces check for update of file size for non-cached 38files. Allow file size to be updated on remote extend of locally open, 39non-cached file. Fix reconnect to newer Samba servers (or other servers 40which support the CIFS Unix/POSIX extensions) so that we again tell the 41server the Unix/POSIX cifs capabilities which we support (SetFSInfo). 42Add experimental support for new POSIX Open/Mkdir (which returns 43stat information on the open, and allows setting the mode). 44 45Version 1.46 46------------ 47Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps. 48Allow null user to be specified on mount ("username="). Do not return 49EINVAL on readdir when filldir fails due to overwritten blocksize 50(fixes FC problem). Return error in rename 2nd attempt retry (ie report 51if rename by handle also fails, after rename by path fails, we were 52not reporting whether the retry worked or not). Fix NTLMv2 to 53work to Windows servers (mount with option "sec=ntlmv2"). 54 55Version 1.45 56------------ 57Do not time out lockw calls when using posix extensions. Do not 58time out requests if server still responding reasonably fast 59on requests on other threads. Improve POSIX locking emulation, 60(lock cancel now works, and unlock of merged range works even 61to Windows servers now). Fix oops on mount to lanman servers 62(win9x, os/2 etc.) when null password. Do not send listxattr 63(SMB to query all EAs) if nouser_xattr specified. Fix SE Linux 64problem (instantiate inodes/dentries in right order for readdir). 65 66Version 1.44 67------------ 68Rewritten sessionsetup support, including support for legacy SMB 69session setup needed for OS/2 and older servers such as Windows 95 and 98. 70Fix oops on ls to OS/2 servers. Add support for level 1 FindFirst 71so we can do search (ls etc.) to OS/2. Do not send NTCreateX 72or recent levels of FindFirst unless server says it supports NT SMBs 73(instead use legacy equivalents from LANMAN dialect). Fix to allow 74NTLMv2 authentication support (now can use stronger password hashing 75on mount if corresponding /proc/fs/cifs/SecurityFlags is set (0x4004). 76Allow override of global cifs security flags on mount via "sec=" option(s). 77 78Version 1.43 79------------ 80POSIX locking to servers which support CIFS POSIX Extensions 81(disabled by default controlled by proc/fs/cifs/Experimental). 82Handle conversion of long share names (especially Asian languages) 83to Unicode during mount. Fix memory leak in sess struct on reconnect. 84Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on 85cifs open which helps rare case when setpathinfo fails or server does 86not support it. 87 88Version 1.42 89------------ 90Fix slow oplock break when mounted to different servers at the same time and 91the tids match and we try to find matching fid on wrong server. Fix read 92looping when signing required by server (2.6.16 kernel only). Fix readdir 93vs. rename race which could cause each to hang. Return . and .. even 94if server does not. Allow searches to skip first three entries and 95begin at any location. Fix oops in find_writeable_file. 96 97Version 1.41 98------------ 99Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can 100configure stronger authentication. Fix sfu symlinks so they can 101be followed (not just recognized). Fix wraparound of bcc on 102read responses when buffer size over 64K and also fix wrap of 103max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in 104cifs_user_read and cifs_readpages (when EAGAIN on send of smb 105on socket is returned over and over). Add POSIX (advisory) byte range 106locking support (requires server with newest CIFS UNIX Extensions 107to the protocol implemented). Slow down negprot slightly in port 139 108RFC1001 case to give session_init time on buggy servers. 109 110Version 1.40 111------------ 112Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance 113of readpages by eliminating one extra memcpy. Allow update of file size 114from remote server even if file is open for write as long as mount is 115directio. Recognize share mode security and send NTLM encrypted password 116on tree connect if share mode negotiated. 117 118Version 1.39 119------------ 120Defer close of a file handle slightly if pending writes depend on that handle 121(this reduces the EBADF bad file handle errors that can be logged under heavy 122stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2 123Fix SFU style symlinks and mknod needed for servers which do not support the 124CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative 125dentries so files that the client sees as deleted but that later get created 126on the server will be recognized. Add client side permission check on setattr. 127Timeout stuck requests better (where server has never responded or sent corrupt 128responses) 129 130Version 1.38 131------------ 132Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket) 133to be smaller at first (but increasing) so large write performance performance 134over GigE is better. Do not hang thread on illegal byte range lock response 135from Windows (Windows can send an RFC1001 size which does not match smb size) by 136allowing an SMBs TCP length to be up to a few bytes longer than it should be. 137wsize and rsize can now be larger than negotiated buffer size if server 138supports large readx/writex, even when directio mount flag not specified. 139Write size will in many cases now be 16K instead of 4K which greatly helps 140file copy performance on lightly loaded networks. Fix oops in dnotify 141when experimental config flag enabled. Make cifsFYI more granular. 142 143Version 1.37 144------------ 145Fix readdir caching when unlink removes file in current search buffer, 146and this is followed by a rewind search to just before the deleted entry. 147Do not attempt to set ctime unless atime and/or mtime change requested 148(most servers throw it away anyway). Fix length check of received smbs 149to be more accurate. Fix big endian problem with mapchars mount option, 150and with a field returned by statfs. 151 152Version 1.36 153------------ 154Add support for mounting to older pre-CIFS servers such as Windows9x and ME. 155For these older servers, add option for passing netbios name of server in 156on mount (servernetbiosname). Add suspend support for power management, to 157avoid cifsd thread preventing software suspend from working. 158Add mount option for disabling the default behavior of sending byte range lock 159requests to the server (necessary for certain applications which break with 160mandatory lock behavior such as Evolution), and also mount option for 161requesting case insensitive matching for path based requests (requesting 162case sensitive is the default). 163 164Version 1.35 165------------ 166Add writepage performance improvements. Fix path name conversions 167for long filenames on mounts which were done with "mapchars" mount option 168specified. Ensure multiplex ids do not collide. Fix case in which 169rmmod can oops if done soon after last unmount. Fix truncated 170search (readdir) output when resume filename was a long filename. 171Fix filename conversion when mapchars mount option was specified and 172filename was a long filename. 173 174Version 1.34 175------------ 176Fix error mapping of the TOO_MANY_LINKS (hardlinks) case. 177Do not oops if root user kills cifs oplock kernel thread or 178kills the cifsd thread (NB: killing the cifs kernel threads is not 179recommended, unmount and rmmod cifs will kill them when they are 180no longer needed). Fix readdir to ASCII servers (ie older servers 181which do not support Unicode) and also require asterisk. 182Fix out of memory case in which data could be written one page 183off in the page cache. 184 185Version 1.33 186------------ 187Fix caching problem, in which readdir of directory containing a file 188which was cached could cause the file's time stamp to be updated 189without invalidating the readahead data (so we could get stale 190file data on the client for that file even as the server copy changed). 191Cleanup response processing so cifsd can not loop when abnormally 192terminated. 193 194 195Version 1.32 196------------ 197Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one 198transact response for an SMB request and search entry split across two frames. 199Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server) 200as new protocol extensions. Do not send Get/Set calls for POSIX ACLs 201unless server explicitly claims to support them in CIFS Unix extensions 202POSIX ACL capability bit. Fix packet signing when multiuser mounting with 203different users from the same client to the same server. Fix oops in 204cifs_close. Add mount option for remapping reserved characters in 205filenames (also allow recognizing files with created by SFU which have any 206of these seven reserved characters, except backslash, to be recognized). 207Fix invalid transact2 message (we were sometimes trying to interpret 208oplock breaks as SMB responses). Add ioctl for checking that the 209current uid matches the uid of the mounter (needed by umount.cifs). 210Reduce the number of large buffer allocations in cifs response processing 211(significantly reduces memory pressure under heavy stress with multiple 212processes accessing the same server at the same time). 213 214Version 1.31 215------------ 216Fix updates of DOS attributes and time fields so that files on NT4 servers 217do not get marked delete on close. Display sizes of cifs buffer pools in 218cifs stats. Fix oops in unmount when cifsd thread being killed by 219shutdown. Add generic readv/writev and aio support. Report inode numbers 220consistently in readdir and lookup (when serverino mount option is 221specified use the inode number that the server reports - for both lookup 222and readdir, otherwise by default the locally generated inode number is used 223for inodes created in either path since servers are not always able to 224provide unique inode numbers when exporting multiple volumes from under one 225sharename). 226 227Version 1.30 228------------ 229Allow new nouser_xattr mount parm to disable xattr support for user namespace. 230Do not flag user_xattr mount parm in dmesg. Retry failures setting file time 231(mostly affects NT4 servers) by retry with handle based network operation. 232Add new POSIX Query FS Info for returning statfs info more accurately. 233Handle passwords with multiple commas in them. 234 235Version 1.29 236------------ 237Fix default mode in sysfs of cifs module parms. Remove old readdir routine. 238Fix capabilities flags for large readx so as to allow reads larger than 64K. 239 240Version 1.28 241------------ 242Add module init parm for large SMB buffer size (to allow it to be changed 243from its default of 16K) which is especially useful for large file copy 244when mounting with the directio mount option. Fix oops after 245returning from mount when experimental ExtendedSecurity enabled and 246SpnegoNegotiated returning invalid error. Fix case to retry better when 247peek returns from 1 to 3 bytes on socket which should have more data. 248Fixed path based calls (such as cifs lookup) to handle path names 249longer than 530 (now can handle PATH_MAX). Fix pass through authentication 250from Samba server to DC (Samba required dummy LM password). 251 252Version 1.27 253------------ 254Turn off DNOTIFY (directory change notification support) by default 255(unless built with the experimental flag) to fix hang with KDE 256file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event 257waiting on an SMB response) in SendReceive when session dies but 258reconnects quickly from another task. Add module init parms for 259minimum number of large and small network buffers in the buffer pools, 260and for the maximum number of simultaneous requests. 261 262Version 1.26 263------------ 264Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later 265and other POSIX CIFS compliant servers. Fix error mapping for getfacl 266to EOPNOTSUPP when server does not support posix acls on the wire. Fix 267improperly zeroed buffer in CIFS Unix extensions set times call. 268 269Version 1.25 270------------ 271Fix internationalization problem in cifs readdir with filenames that map to 272longer UTF-8 strings than the string on the wire was in Unicode. Add workaround 273for readdir to netapp servers. Fix search rewind (seek into readdir to return 274non-consecutive entries). Do not do readdir when server negotiates 275buffer size to small to fit filename. Add support for reading POSIX ACLs from 276the server (add also acl and noacl mount options). 277 278Version 1.24 279------------ 280Optionally allow using server side inode numbers, rather than client generated 281ones by specifying mount option "serverino" - this is required for some apps 282to work which double check hardlinked files and have persistent inode numbers. 283 284Version 1.23 285------------ 286Multiple bigendian fixes. On little endian systems (for reconnect after 287network failure) fix tcp session reconnect code so we do not try first 288to reconnect on reverse of port 445. Treat reparse points (NTFS junctions) 289as directories rather than symlinks because we can do follow link on them. 290 291Version 1.22 292------------ 293Add config option to enable XATTR (extended attribute) support, mapping 294xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of 295minor fixes pointed out by the Stanford SWAT checker (mostly missing 296or out of order NULL pointer checks in little used error paths). 297 298Version 1.21 299------------ 300Add new mount parm to control whether mode check (generic_permission) is done 301on the client. If Unix extensions are enabled and the uids on the client 302and server do not match, client permission checks are meaningless on 303server uids that do not exist on the client (this does not affect the 304normal ACL check which occurs on the server). Fix default uid 305on mknod to match create and mkdir. Add optional mount parm to allow 306override of the default uid behavior (in which the server sets the uid 307and gid of newly created files). Normally for network filesystem mounts 308user want the server to set the uid/gid on newly created files (rather than 309using uid of the client processes you would in a local filesystem). 310 311Version 1.20 312------------ 313Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps 314info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir 315(in build_wildcard_path_from_dentry). Fix mknod to pass type field 316(block/char/fifo) properly. Remove spurious mount warning log entry when 317credentials passed as mount argument. Set major/minor device number in 318inode for block and char devices when unix extensions enabled. 319 320Version 1.19 321------------ 322Fix /proc/fs/cifs/Stats and DebugData display to handle larger 323amounts of return data. Properly limit requests to MAX_REQ (50 324is the usual maximum active multiplex SMB/CIFS requests per server). 325Do not kill cifsd (and thus hurt the other SMB session) when more than one 326session to the same server (but with different userids) exists and one 327of the two user's smb sessions is being removed while leaving the other. 328Do not loop reconnecting in cifsd demultiplex thread when admin 329kills the thread without going through unmount. 330 331Version 1.18 332------------ 333Do not rename hardlinked files (since that should be a noop). Flush 334cached write behind data when reopening a file after session abend, 335except when already in write. Grab per socket sem during reconnect 336to avoid oops in sendmsg if overlapping with reconnect. Do not 337reset cached inode file size on readdir for files open for write on 338client. 339 340 341Version 1.17 342------------ 343Update number of blocks in file so du command is happier (in Linux a fake 344blocksize of 512 is required for calculating number of blocks in inode). 345Fix prepare write of partial pages to read in data from server if possible. 346Fix race on tcpStatus field between unmount and reconnection code, causing 347cifsd process sometimes to hang around forever. Improve out of memory 348checks in cifs_filldir 349 350Version 1.16 351------------ 352Fix incorrect file size in file handle based setattr on big endian hardware. 353Fix oops in build_path_from_dentry when out of memory. Add checks for invalid 354and closing file structs in writepage/partialpagewrite. Add statistics 355for each mounted share (new menuconfig option). Fix endianness problem in 356volume information displayed in /proc/fs/cifs/DebugData (only affects 357affects big endian architectures). Prevent renames while constructing 358path names for open, mkdir and rmdir. 359 360Version 1.15 361------------ 362Change to mempools for alloc smb request buffers and multiplex structs 363to better handle low memory problems (and potential deadlocks). 364 365Version 1.14 366------------ 367Fix incomplete listings of large directories on Samba servers when Unix 368extensions enabled. Fix oops when smb_buffer can not be allocated. Fix 369rename deadlock when writing out dirty pages at same time. 370 371Version 1.13 372------------ 373Fix open of files in which O_CREATE can cause the mode to change in 374some cases. Fix case in which retry of write overlaps file close. 375Fix PPC64 build error. Reduce excessive stack usage in smb password 376hashing. Fix overwrite of Linux user's view of file mode to Windows servers. 377 378Version 1.12 379------------ 380Fixes for large file copy, signal handling, socket retry, buffer 381allocation and low memory situations. 382 383Version 1.11 384------------ 385Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize) 386also now allowing support for specifying client netbiosname. NT4 support added. 387 388Version 1.10 389------------ 390Fix reconnection (and certain failed mounts) to properly wake up the 391blocked users thread so it does not seem hung (in some cases was blocked 392until the cifs receive timeout expired). Fix spurious error logging 393to kernel log when application with open network files killed. 394 395Version 1.09 396------------ 397Fix /proc/fs module unload warning message (that could be logged 398to the kernel log). Fix intermittent failure in connectathon 399test7 (hardlink count not immediately refreshed in case in which 400inode metadata can be incorrectly kept cached when time near zero) 401 402Version 1.08 403------------ 404Allow file_mode and dir_mode (specified at mount time) to be enforced 405locally (the server already enforced its own ACLs too) for servers 406that do not report the correct mode (do not support the 407CIFS Unix Extensions). 408 409Version 1.07 410------------ 411Fix some small memory leaks in some unmount error paths. Fix major leak 412of cache pages in readpages causing multiple read oriented stress 413testcases (including fsx, and even large file copy) to fail over time. 414 415Version 1.06 416------------ 417Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server. 418This allows files that differ only in case and improves performance of file 419creation and file open to such servers. Fix semaphore conflict which causes 420slow delete of open file to Samba (which unfortunately can cause an oplock 421break to self while vfs_unlink held i_sem) which can hang for 20 seconds. 422 423Version 1.05 424------------ 425fixes to cifs_readpages for fsx test case 426 427Version 1.04 428------------ 429Fix caching data integrity bug when extending file size especially when no 430oplock on file. Fix spurious logging of valid already parsed mount options 431that are parsed outside of the cifs vfs such as nosuid. 432 433 434Version 1.03 435------------ 436Connect to server when port number override not specified, and tcp port 437unitialized. Reset search to restart at correct file when kernel routine 438filldir returns error during large directory searches (readdir). 439 440Version 1.02 441------------ 442Fix caching problem when files opened by multiple clients in which 443page cache could contain stale data, and write through did 444not occur often enough while file was still open when read ahead 445(read oplock) not allowed. Treat "sep=" when first mount option 446as an override of comma as the default separator between mount 447options. 448 449Version 1.01 450------------ 451Allow passwords longer than 16 bytes. Allow null password string. 452 453Version 1.00 454------------ 455Gracefully clean up failed mounts when attempting to mount to servers such as 456Windows 98 that terminate tcp sessions during protocol negotiation. Handle 457embedded commas in mount parsing of passwords. 458 459Version 0.99 460------------ 461Invalidate local inode cached pages on oplock break and when last file 462instance is closed so that the client does not continue using stale local 463copy rather than later modified server copy of file. Do not reconnect 464when server drops the tcp session prematurely before negotiate 465protocol response. Fix oops in reopen_file when dentry freed. Allow 466the support for CIFS Unix Extensions to be disabled via proc interface. 467 468Version 0.98 469------------ 470Fix hang in commit_write during reconnection of open files under heavy load. 471Fix unload_nls oops in a mount failure path. Serialize writes to same socket 472which also fixes any possible races when cifs signatures are enabled in SMBs 473being sent out of signature sequence number order. 474 475Version 0.97 476------------ 477Fix byte range locking bug (endian problem) causing bad offset and 478length. 479 480Version 0.96 481------------ 482Fix oops (in send_sig) caused by CIFS unmount code trying to 483wake up the demultiplex thread after it had exited. Do not log 484error on harmless oplock release of closed handle. 485 486Version 0.95 487------------ 488Fix unsafe global variable usage and password hash failure on gcc 3.3.1 489Fix problem reconnecting secondary mounts to same server after session 490failure. Fix invalid dentry - race in mkdir when directory gets created 491by another client between the lookup and mkdir. 492 493Version 0.94 494------------ 495Fix to list processing in reopen_files. Fix reconnection when server hung 496but tcpip session still alive. Set proper timeout on socket read. 497 498Version 0.93 499------------ 500Add missing mount options including iocharset. SMP fixes in write and open. 501Fix errors in reconnecting after TCP session failure. Fix module unloading 502of default nls codepage 503 504Version 0.92 505------------ 506Active smb transactions should never go negative (fix double FreeXid). Fix 507list processing in file routines. Check return code on kmalloc in open. 508Fix spinlock usage for SMP. 509 510Version 0.91 511------------ 512Fix oops in reopen_files when invalid dentry. drop dentry on server rename 513and on revalidate errors. Fix cases where pid is now tgid. Fix return code 514on create hard link when server does not support them. 515 516Version 0.90 517------------ 518Fix scheduling while atomic error in getting inode info on newly created file. 519Fix truncate of existing files opened with O_CREAT but not O_TRUNC set. 520 521Version 0.89 522------------ 523Fix oops on write to dead tcp session. Remove error log write for case when file open 524O_CREAT but not O_EXCL 525 526Version 0.88 527------------ 528Fix non-POSIX behavior on rename of open file and delete of open file by taking 529advantage of trans2 SetFileInfo rename facility if available on target server. 530Retry on ENOSPC and EAGAIN socket errors. 531 532Version 0.87 533------------ 534Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix 535allocation size miscalculation. After oplock token lost do not read through 536cache. 537 538Version 0.86 539------------ 540Fix oops on empty file readahead. Fix for file size handling for locally cached files. 541 542Version 0.85 543------------ 544Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files 545during auto reconnection to server after server recovered from failure. 546 547Version 0.84 548------------ 549Finish support for Linux 2.5 open/create changes, which removes the 550redundant NTCreate/QPathInfo/close that was sent during file create. 551Enable oplock by default. Enable packet signing by default (needed to 552access many recent Windows servers) 553 554Version 0.83 555------------ 556Fix oops when mounting to long server names caused by inverted parms to kmalloc. 557Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled 558we will choose a cifs user session (smb uid) that better matches the local 559uid if a) the mount uid does not match the current uid and b) we have another 560session to the same server (ip address) for a different mount which 561matches the current local uid. 562 563Version 0.82 564------------ 565Add support for mknod of block or character devices.

This should help Windows 2003 573network interoperability since it is common for 574packet signing to be required now. Fix statfs (stat -f) 575which recently started returning errors due to 576invalid value (-1 instead of 0) being set in the 577struct kstatfs f_ffiles field. 578 579Version 0.80 580----------- 581Fix oops on stopping oplock thread when removing cifs when 582built as module. 583 584Version 0.79 585------------ 586Fix mount options for ro (readonly), uid, gid and file and directory mode. 587 588Version 0.78 589------------ 590Fix errors displayed on failed mounts to be more understandable. 591Fixed various incorrect or misleading smb to posix error code mappings. 592 593Version 0.77 594------------ 595Fix display of NTFS DFS junctions to display as symlinks. 596They are the network equivalent.

Allow "-ip=" new 645mount option to be passed in on parameter distinct from the first part 646(server name portion of) the UNC name. Allow override of the 647tcp port of the target server via new mount option "-port=" 648 649Version 0.68 650------------ 651Fix search handle leak on rewind. Fix setuid and gid so that they are 652reflected in the local inode immediately. Cleanup of whitespace 653to make 2.4 and 2.5 versions more consistent. 654 655 656Version 0.67 657------------ 658Fix signal sending so that captive thread (cifsd) exits on umount 659(which was causing the warning in kmem_cache_free of the request buffers 660at rmmod time). This had broken as a sideeffect of the recent global 661kernel change to daemonize. Fix memory leak in readdir code which 662showed up in "ls -R" (and applications that did search rewinding). 663 664Version 0.66 665------------ 666Reconnect tids and fids after session reconnection (still do not 667reconnect byte range locks though). Fix problem caching 668lookup information for directory inodes, improving performance, 669especially in deep directory trees. Fix various build warnings. 670 671Version 0.65 672------------ 673Finish fixes to commit write for caching/readahead consistency. fsx 674now works to Samba servers.

Add generic sendfile support. 682 683Version 0.63 684------------ 685Fix memory leak in AllocMidQEntry. 686Finish reconnection logic, so connection with server can be dropped 687(or server rebooted) and the cifs client will reconnect. 688 689Version 0.62 690------------ 691Fix temporary socket leak when bad userid or password specified 692(or other SMBSessSetup failure). Increase maximum buffer size to slightly 693over 16K to allow negotiation of up to Samba and Windows server default read 694sizes. Add support for readpages 695 696Version 0.61 697------------ 698Fix oops when username not passed in on mount. Extensive fixes and improvements 699to error logging (strip redundant newlines, change debug macros to ensure newline 700passed in and to be more consistent). Fix writepage wrong file handle problem, 701a readonly file handle could be incorrectly used to attempt to write out 702file updates through the page cache to multiply open files. This could cause 703the iozone benchmark to fail on the fwrite test. Fix bug mounting two different 704shares to the same Windows server when using different usernames 705(doing this to Samba servers worked but Windows was rejecting it) - now it is 706possible to use different userids when connecting to the same server from a 707Linux client. Fix oops when treeDisconnect called during unmount on 708previously freed socket. 709 710Version 0.60 711------------ 712Fix oops in readpages caused by not setting address space operations in inode in 713rare code path. 714 715Version 0.59 716------------ 717Includes support for deleting of open files and renaming over existing files (per POSIX 718requirement).

Additional formatting cleanup. 730 731Version 0.56 732------------ 733Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup. 734 735Version 0.55 736------------ 737Fixes from Zwane Mwaikambo for adding missing return code checking in a few places. 738Also included a modified version of his fix to protect global list manipulation of 739the smb session and tree connection and mid related global variables. 740 741Version 0.54 742------------ 743Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre 744changes to superblock layout. Remove wasteful allocation of smb buffers (now the send 745buffer is reused for responses). Add more oplock handling. Additional minor cleanup. 746 747Version 0.53 748------------ 749More stylistic updates to better match kernel style. Add additional statistics 750for filesystem which can be viewed via /proc/fs/cifs.

Directory caching fixed so hardlinked 807files now return the correct number of links on fstat as they are repeatedly linked and unlinked. 808 809Version 0.40 810------------ 811Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate 812session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP. 813Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs 814(which is the mechanism preferred by Windows 2000 server in the absence of Kerberos). 815 816Version 0.38 817------------ 818Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable 819it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU). 820 821Version 0.37 822------------ 823Rewrote much of connection and mount/unmount logic to handle bugs with 824multiple uses to same share, multiple users to same server etc. 825 826Version 0.36 827------------ 828Fixed major problem with dentry corruption (missing call to dput) 829 830Version 0.35 831------------ 832Rewrite of readdir code to fix bug.
