Version 1.13 ------------ Fix open of files in which O_CREATE can cause the mode to change in some cases. Fix case in which retry of write overlaps file close. Fix PPC64 build error. Version 1.12 ------------ Fixes for large file copy, signal handling, socket retry, buffer allocation and low memory situations.

Version 1.10 ------------ Fix reconnection (and certain failed mounts) to properly wake up the blocked users thread so it does not seem hung (in some cases was blocked until the cifs receive timeout expired). Fix spurious error logging to kernel log when application with open network files killed. Version 1.09 ------------ Fix /proc/fs module unload warning message (that could be logged to the kernel log). Fix intermittent failure in connectathon test7 (hardlink count not immediately refreshed in case in which inode metadata can be incorrectly kept cached when time near zero) Version 1.08 ------------ Allow file_mode and dir_mode (specified at mount time) to be enforced locally (the server already enforced its own ACLs too) for servers that do not report the correct mode (do not support the CIFS Unix Extensions). Version 1.07 ------------ Fix some small memory leaks in some unmount error paths. Fix major leak of cache pages in readpages causing multiple read oriented stress testcases (including fsx, and even large file copy) to fail over time. Version 1.06 ------------ Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server. This allows files that differ only in case and improves performance of file creation and file open to such servers. Fix semaphore conflict which causes slow delete of open file to Samba (which unfortunately can cause an oplock break to self while vfs_unlink held i_sem) which can hang for 20 seconds. Version 1.05 ------------ fixes to cifs_readpages for fsx test case Version 1.04 ------------ Fix caching data integrity bug when extending file size especially when no oplock on file. Fix spurious logging of valid already parsed mount options that are parsed outside of the cifs vfs such as nosuid. Version 1.03 ------------ Connect to server when port number override not specified, and tcp port unitialized. Reset search to restart at correct file when kernel routine filldir returns error during large directory searches (readdir). Version 1.02 ------------ Fix caching problem when files opened by multiple clients in which page cache could contain stale data, and write through did not occur often enough while file was still open when read ahead (read oplock) not allowed. Treat "sep=" when first mount option as an overrride of comma as the default separator between mount options. Version 1.01 ------------ Allow passwords longer than 16 bytes. Allow null password string. Version 1.00 ------------ Gracefully clean up failed mounts when attempting to mount to servers such as Windows 98 that terminate tcp sessions during prototocol negotiation. Handle embedded commas in mount parsing of passwords. Version 0.99 ------------ Invalidate local inode cached pages on oplock break and when last file instance is closed so that the client does not continue using stale local copy rather than later modified server copy of file. Do not reconnect when server drops the tcp session prematurely before negotiate protocol response. Fix oops in roepen_file when dentry freed. Allow the support for CIFS Unix Extensions to be disabled via proc interface. Version 0.98 ------------ Fix hang in commit_write during reconnection of open files under heavy load. Fix unload_nls oops in a mount failure path. Serialize writes to same socket which also fixes any possible races when cifs signatures are enabled in SMBs being sent out of signature sequence number order.

Version 0.96 ------------ Fix oops (in send_sig) caused by CIFS unmount code trying to wake up the demultiplex thread after it had exited. Do not log error on harmless oplock release of closed handle. Version 0.95 ------------ Fix unsafe global variable usage and password hash failure on gcc 3.3.1 Fix problem reconnecting secondary mounts to same server after session failure. Fix invalid dentry - race in mkdir when directory gets created by another client between the lookup and mkdir. Version 0.94 ------------ Fix to list processing in reopen_files. Fix reconnection when server hung but tcpip session still alive. Set proper timeout on socket read. Version 0.93 ------------ Add missing mount options including iocharset.

Version 0.89 ------------ Fix oops on write to dead tcp session. Remove error log write for case when file open O_CREAT but not O_EXCL Version 0.88 ------------ Fix non-POSIX behavior on rename of open file and delete of open file by taking advantage of trans2 SetFileInfo rename facility if available on target server. Retry on ENOSPC and EAGAIN socket errors. Version 0.87 ------------ Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix allocation size miscalculation. After oplock token lost do not read through cache. Version 0.86 ------------ Fix oops on empty file readahead. Fix for file size handling for locally cached files. Version 0.85 ------------ Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files during auto reconnection to server after server recovered from failure. Version 0.84 ------------ Finish support for Linux 2.5 open/create changes, which removes the redundant NTCreate/QPathInfo/close that was sent during file create. Enable oplock by default. Enable packet signing by default (needed to access many recent Windows servers) Version 0.83 ------------ Fix oops when mounting to long server names caused by inverted parms to kmalloc. Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled we will choose a cifs user session (smb uid) that better matches the local uid if a) the mount uid does not match the current uid and b) we have another session to the same server (ip address) for a different mount which matches the current local uid. Version 0.82 ------------ Add support for mknod of block or character devices. Fix oplock code (distributed caching) to properly send response to oplock break from server. Version 0.81 ------------ Finish up CIFS packet digital signing for the default NTLM security case. This should help Windows 2003 network interoperability since it is common for packet signing to be required now. Fix statfs (stat -f) which recently started returning errors due to invalid value (-1 instead of 0) being set in the struct kstatfs f_ffiles field. Version 0.80 ----------- Fix oops on stopping oplock thread when removing cifs when built as module. Version 0.79 ------------ Fix mount options for ro (readonly), uid, gid and file and directory mode. Version 0.78 ------------ Fix errors displayed on failed mounts to be more understandable.

Version 0.72 ------------ Add resume key support to search (readdir) code to workaround Windows bug. Add /proc/fs/cifs/LookupCacheEnable which allows disabling caching of attribute information for lookups. Version 0.71 ------------ Add more oplock handling (distributed caching code). Remove dead code. Remove excessive stack space utilization from symlink routines. Version 0.70 ------------ Fix oops in get dfs referral (triggered when null path sent in to mount). Add support for overriding rsize at mount time. Version 0.69 ------------ Fix buffer overrun in readdir which caused intermittent kernel oopses. Fix writepage code to release kmap on write data. Allow "-ip=" new mount option to be passed in on parameter distinct from the first part (server name portion of) the UNC name. Allow override of the tcp port of the target server via new mount option "-port=" Version 0.68 ------------ Fix search handle leak on rewind. Fix setuid and gid so that they are reflected in the local inode immediately. Cleanup of whitespace to make 2.4 and 2.5 versions more consistent. Version 0.67 ------------ Fix signal sending so that captive thread (cifsd) exits on umount (which was causing the warning in kmem_cache_free of the request buffers at rmmod time). This had broken as a sideeffect of the recent global kernel change to daemonize. Fix memory leak in readdir code which showed up in "ls -R" (and applications that did search rewinding). Version 0.66 ------------ Reconnect tids and fids after session reconnection (still do not reconnect byte range locks though). Fix problem caching lookup information for directory inodes, improving performance, especially in deep directory trees. Fix various build warnings. Version 0.65 ------------ Finish fixes to commit write for caching/readahead consistency. fsx now works to Samba servers. Fix oops caused when readahead was interrupted by a signal. Version 0.64 ------------ Fix data corruption (in partial page after truncate) that caused fsx to fail to Windows servers. Cleaned up some extraneous error logging in common error paths. Add generic sendfile support. Version 0.63 ------------ Fix memory leak in AllocMidQEntry. Finish reconnection logic, so connection with server can be dropped (or server rebooted) and the cifs client will reconnect. Version 0.62 ------------ Fix temporary socket leak when bad userid or password specified (or other SMBSessSetup failure). Increase maximum buffer size to slightly over 16K to allow negotiation of up to Samba and Windows server default read sizes. Add support for readpages Version 0.61 ------------ Fix oops when username not passed in on mount. Extensive fixes and improvements to error logging (strip redundant newlines, change debug macros to ensure newline passed in and to be more consistent). Fix writepage wrong file handle problem, a readonly file handle could be incorrectly used to attempt to write out file updates through the page cache to multiply open files. This could cause the iozone benchmark to fail on the fwrite test. Fix bug mounting two different shares to the same Windows server when using different usernames (doing this to Samba servers worked but Windows was rejecting it) - now it is possible to use different userids when connecting to the same server from a Linux client. Fix oops when treeDisconnect called during unmount on previously freed socket. Version 0.60 ------------ Fix oops in readpages caused by not setting address space operations in inode in rare code path. Version 0.59 ------------ Includes support for deleting of open files and renaming over existing files (per POSIX requirement). Add readlink support for Windows junction points (directory symlinks). Version 0.58 ------------ Changed read and write to go through pagecache. Added additional address space operations. Memory mapped operations now working.

Version 0.54 ------------ Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre changes to superblock layout. Remove wasteful allocation of smb buffers (now the send buffer is reused for responses). Add more oplock handling. Additional minor cleanup. Version 0.53 ------------ More stylistic updates to better match kernel style. Add additional statistics for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2 and CIFS Packet Signing enablement. Version 0.52 ------------ Replace call to sleep_on with safer wait_on_event. Make stylistic changes to better match kernel style recommendations. Remove most typedef usage (except for the PDUs themselves). Version 0.51 ------------ Update mount so the -unc mount option is no longer required (the ip address can be specified in a UNC style device name. Implementation of readpage/writepage started. Version 0.50 ------------ Fix intermittent problem with incorrect smb header checking on badly fragmented tcp responses Version 0.49 ------------ Fixes to setting of allocation size and file size. Version 0.48 ------------ Various 2.5.38 fixes. Now works on 2.5.38 Version 0.47 ------------ Prepare for 2.5 kernel merge. Remove ifdefs. Version 0.46 ------------ Socket buffer management fixes.

Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7). Version 0.41 ------------ Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked files now return the correct rumber of links on fstat as they are repeatedly linked and unlinked. Version 0.40 ------------ Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP. Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs (which is the mechanism preferred by Windows 2000 server in the absence of Kerberos). Version 0.38 ------------ Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU). Version 0.37 ------------ Rewrote much of connection and mount/unmount logic to handle bugs with multiple uses to same share, multiple users to same server etc. Version 0.36 ------------ Fixed major problem with dentry corruption (missing call to dput) Version 0.35 ------------ Rewrite of readdir code to fix bug. Various fixes for bigendian machines. Begin adding oplock support.

Version 0.32 ------------ Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented and tested against Samba 2.2.5 Version 0.31 ------------ 1) Fixed lockrange to be correct (it was one byte too short) 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly show range as locked when there is a conflict with an existing lock. 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories in most cases. Eventually will offer optional ability to query server for the correct perms. 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb session) 4) Fixed error logging of valid mount options 5) Removed logging of password field. 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c and cleaned them up and made them more consistent with other cifs functions. 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways (with or without Unix exentions) but FindNext and QueryPathInfo with the Unix extensions are not completed, nor is the symlink support using the Unix extensions 8) Started adding the readlink and follow_link code Version 0.3 ----------- Initial drop
