Fix mknod to pass type field +(block/char/fifo) properly. Remove spurious mount warning log entry when +credentials passed as mount argument. Set major/minor device number in +inode for block and char devices when unix extensions enabled. + +Version 1.19 +------------ +Fix /proc/fs/cifs/Stats and DebugData display to handle larger +amounts of return data. Properly limit requests to MAX_REQ (50 +is the usual maximum active multiplex SMB/CIFS requests per server). +Do not kill cifsd (and thus hurt the other SMB session) when more than one +session to the same server (but with different userids) exists and one +of the two user's smb sessions is being removed while leaving the other. +Do not loop reconnecting in cifsd demultiplex thread when admin +kills the thread without going through unmount. + +Version 1.18 +------------ +Do not rename hardlinked files (since that should be a noop). Flush +cached write behind data when reopening a file after session abend, +except when already in write. Grab per socket sem during reconnect +to avoid oops in sendmsg if overlapping with reconnect. Do not +reset cached inode file size on readdir for files open for write on +client. + + +Version 1.17 +------------ +Update number of blocks in file so du command is happier (in Linux a fake +blocksize of 512 is required for calculating number of blocks in inode). +Fix prepare write of partial pages to read in data from server if possible. +Fix race on tcpStatus field between unmount and reconnection code, causing +cifsd process sometimes to hang around forever. Improve out of memory +checks in cifs_filldir + +Version 1.16 +------------ +Fix incorrect file size in file handle based setattr on big endian hardware. +Fix oops in build_path_from_dentry when out of memory. Add checks for invalid +and closing file structs in writepage/partialpagewrite. Add statistics +for each mounted share (new menuconfig option). Fix endianness problem in +volume information displayed in /proc/fs/cifs/DebugData (only affects +affects big endian architectures). Prevent renames while constructing +path names for open, mkdir and rmdir. + +Version 1.15 +------------ +Change to mempools for alloc smb request buffers and multiplex structs +to better handle low memory problems (and potential deadlocks). + +Version 1.14 +------------ +Fix incomplete listings of large directories on Samba servers when Unix +extensions enabled. Fix oops when smb_buffer can not be allocated. Fix +rename deadlock when writing out dirty pages at same time. + +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. Reduce excessive stack usage in smb password +hashing. Fix overwrite of Linux user's view of file mode to Windows servers. + +Version 1.12 +------------ +Fixes for large file copy, signal handling, socket retry, buffer +allocation and low memory situations. + +Version 1.11 +------------ +Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize) +also now allowing support for specifying client netbiosname. NT4 support added. + +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 0.97 +------------ +Fix byte range locking bug (endian problem) causing bad offset and +length. + +Version 0.96 +------------ +Fix oops (in send_sig) caused by CIFS unmount code trying to +wake up the demultiplex thread after it had exited.

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.

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.

Formatting cleanup. + +Version 0.55 +------------ +Fixes from Zwane Mwaikambo for adding missing return code checking in a few places. +Also included a modified version of his fix to protect global list manipulation of +the smb session and tree connection and mid related global variables. + +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.

To enable the Unix CIFS Extensions in the Samba server, add +the line: + + unix extensions = yes + +to your smb.conf file on the server. Note that the following smb.conf settings +are also useful (on the Samba server) when the majority of clients are Unix or +Linux: + + case sensitive = yes + delete readonly = yes + ea support = yes + +Note that ea support is required for supporting Linux xattrs. +Some administrators also change the "map archive" and the "create mask" +parameters from their default values. Creating special devices (mknod) +remotely may require specifying a mkdev function to Samba if you are not using +Samba 3.0.5 or later. For more information on these see the manual pages +("man smb.conf") on the Samba server system. Note that the cifs vfs, +unlike the smbfs vfs, does not read the smb.conf on the client system +(the few optional settings are passed in on mount via -o parameters instead). +Note that Samba 2.2.7 or later includes a fix that allows the CIFS VFS to delete +open files (required for strict POSIX compliance). Windows Servers already +supported this feature. Samba server does not allow symlinks that refer to files +outside of the share, so in Samba versions prior to 3.0.5, most symlinks to +files with absolute paths (ie beginning with slash) such as: + ln -s /mnt/foo bar +would be forbidden. Samba 3.0.5 server or later includes the ability to create +such symlinks safely by converting unsafe symlinks (ie symlinks to server +files that are outside of the share) to a samba specific format on the server +that is ignored by local server applications and non-cifs clients and that will +not be traversed by the Samba server). This is opaque to the Linux client +application using the cifs vfs. Absolute symlinks will work to Samba 3.0.5 or +later, but only for remote clients using the CIFS Unix extensions, and will +be invisbile to Windows clients and typically will not affect local +applications running on the same server as Samba. + +Use instructions: +================ +Once the CIFS VFS support is built into the kernel or installed as a module +(cifs.o), you can use mount syntax like the following to access Samba or Windows +servers: + + mount -t cifs //9.53.216.11/e$ /mnt -o user=myname,pass=mypassword + +Before -o the option -v may be specified to make the mount.cifs +mount helper display the mount steps more verbosely. +After -o the following commonly used cifs vfs specific options +are supported: + + user=<username> + pass=<password> + domain=<domain name> + +Other cifs mount options are described below. Use of TCP names (in addition to +ip addresses) is available if the mount helper (mount.cifs) is installed. If +you do not trust the server to which are mounted, or if you do not have +cifs signing enabled (and the physical network is insecure), consider use +of the standard mount options "noexec" and "nosuid" to reduce the risk of +running an altered binary on your local system (downloaded from a hostile server +or altered by a hostile router). + +When using the mount helper mount.cifs, passwords may be specified via alternate +mechanisms, instead of specifying it after -o using the normal "pass=" syntax +on the command line: +1) By including it in a credential file. Specify credentials=filename as one +of the mount options. Credential files contain two lines + username=someuser + password=your_password +2) By specifying the password in the PASSWD environment variable (similarly +the user name can be taken from the USER environment variable). +3) By specifying the password in a file by name via PASSWD_FILE +4) By specifying the password in a file by file descriptor via PASSWD_FD + +If no password is provided, mount.cifs will prompt for password entry + +Restrictions +============ +Servers must support the NTLM SMB dialect (which is the most recent, supported +by Samba and Windows NT version 4, 2000 and XP and many other SMB/CIFS servers) +Servers must support either "pure-TCP" (port 445 TCP/IP CIFS connections) or RFC +1001/1002 support for "Netbios-Over-TCP/IP." Neither of these is likely to be a +problem as most servers support this. IPv6 support is planned for the future. + +CIFS VFS Mount Options +====================== +A partial list of the supported mount options follows: + user The user name to use when trying to establish + the CIFS session. + password The user password. If the mount helper is + installed, the user will be prompted for password + if it is not supplied. + ip The ip address of the target server + unc The target server Universal Network Name (export) to + mount. + domain Set the SMB/CIFS workgroup name prepended to the + username during CIFS session establishment + uid If CIFS Unix extensions are not supported by the server + this overrides the default uid for inodes. For mounts to + servers which do support the CIFS Unix extensions, such + as a properly configured Samba server, the server provides + the uid, gid and mode. For servers which do not support + the Unix extensions, the default uid (and gid) returned on + lookup of existing files is the uid (gid) of the person + who executed the mount (root, except when mount.cifs + is configured setuid for user mounts) unless the "uid=" + (gid) mount option is specified. For the uid (gid) of newly + created files and directories, ie files created since + the last mount of the server share, the expected uid + (gid) is cached as as long as the inode remains in + memory on the client. Also note that permission + checks (authorization checks) on accesses to a file occur + at the server, but there are cases in which an administrator + may want to restrict at the client as well. For those + servers which do not report a uid/gid owner + (such as Windows), permissions can also be checked at the + client, and a crude form of client side permission checking + can be enabled by specifying file_mode and dir_mode on + the client + gid If CIFS Unix extensions are not supported by the server + this overrides the default gid for inodes. + file_mode If CIFS Unix extensions are not supported by the server + this overrides the default mode for file inodes. + dir_mode If CIFS Unix extensions are not supported by the server + this overrides the default mode for directory inodes. + port attempt to contact the server on this tcp port, before + trying the usual ports (port 445, then 139). + iocharset Codepage used to convert local path names to and from + Unicode. Unicode is used by default for network path + names if the server supports it. If iocharset is + not specified then the nls_default specified + during the local client kernel build will be used. + If server does not support Unicode, this parameter is + unused. + rsize default read size + wsize default write size + rw mount the network share read-write (note that the + server may still consider the share read-only) + ro mount network share read-only + version used to distinguish different versions of the + mount helper utility (not typically needed) + sep if first mount option (after the -o), overrides + the comma as the separator between the mount + parms. e.g. + -o user=myname,password=mypassword,domain=mydom + could be passed instead with period as the separator by + -o sep=.user=myname.password=mypassword.domain=mydom + this might be useful when comma is contained within username + or password or domain. This option is less important + when the cifs mount helper cifs.mount (version 1.1 or later) + is used. + nosuid Do not allow remote executables with the suid bit + program to be executed. This is only meaningful for mounts + to servers such as Samba which support the CIFS Unix Extensions. + If you do not trust the servers in your network (your mount + targets) it is recommended that you specify this option for + greater security. + suid Allow remote files on this mountpoint with suid enabled to + be executed (default for mounts when executed as root, + nosuid is default for user mounts). + credentials Although ignored by the cifs kernel component, it is used by + the mount helper, mount.cifs. When mount.cifs is installed it + opens and reads the credential file specified in order + to obtain the userid and password arguments which are passed to + the cifs vfs. + guest Although ignored by the kernel component, the mount.cifs + mount helper will not prompt the user for a password + if guest is specified on the mount options. If no + password is specified a null password will be used. + +The mount.cifs mount helper also accepts a few mount options before -o +including: + + -S take password from stdin (equivalent to setting the environment + variable "PASSWD_FD=0" + -V print mount.cifs version + -? display simple usage information + +With recent 2.6 kernel versions of modutils, the version of the cifs kernel +module can be displayed via modinfo. + +Misc /proc/fs/cifs Flags and Debug Info +======================================= +Informational pseudo-files: +DebugData Displays information about active CIFS sessions + and shares. +Stats Lists summary resource usage information as well as per + share statistics, if CONFIG_CIFS_STATS in enabled + in the kernel configuration. + +Configuration pseudo-files: +MultiuserMount If set to one, more than one CIFS session to + the same server ip address can be established + if more than one uid accesses the same mount + point and if the uids user/password mapping + information is available.
