++CIFS (Common Internet File System) support
++CONFIG_CIFS
++ This is the client VFS module for the Common Internet File System
++ (CIFS) protocol which is the successor to the Server Message Block
++ (SMB) protocol, the native file sharing mechanism for most early
++ PC operating systems. CIFS is fully supported by current network
++ file servers such as Windows 2000, Windows 2003 (including
++ Windows XP) as well by Samba (which provides excellent CIFS
++ server support for Linux and many other operating systems).
++ The smbfs module should be used instead of this cifs module for
++ mounting to older SMB servers such as OS/2. The smbfs and cifs
++ modules can coexist and do not conflict.
++
++ The intent of this module is to provide the most advanced network
++ file system function for CIFS compliant servers, including better
++ POSIX compliance, secure per-user session establishment, high
++ performance safe distributed caching (oplock), optional packet
++ signing, Unicode support and other internationalization improvements
++ For more information see the project page at
++ http://us1.samba.org/samba/Linux_CIFS_client.html
++
++CIFS Debugging
++CONFIG_CIFS_DEBUG
++ If you are experiencing any problems with the CIFS filesystem, say
++ Y here. This will result in additional debugging messages to be
++ written to the system log. Under normal circumstances, this
++ results in very little overhead.

++ This is the client VFS module for the Common Internet File System
++ (CIFS) protocol which is the successor to the Server Message Block
++ (SMB) protocol, the native file sharing mechanism for most early
++ PC operating systems. CIFS is fully supported by current network
++ file servers such as Windows 2000, Windows 2003 (including
++ Windows XP) as well by Samba (which provides excellent CIFS
++ server support for Linux and many other operating systems), so
++ this network filesystem client can mount to a wide variety of
++ servers. The smbfs module should be used instead of this cifs module
++ for mounting to older SMB servers such as OS/2. The smbfs and cifs
++ modules can coexist and do not conflict. The CIFS VFS filesystem
++ module is designed to work well with servers that implement the
++ newer versions (dialects) of the SMB/CIFS protocol such as Samba,
++ the program written by Andrew Tridgell that turns any Unix host
++ into a SMB/CIFS file server.
++
++ The intent of this module is to provide the most advanced network
++ file system function for CIFS compliant servers, including better
++ POSIX compliance, secure per-user session establishment, high
++ performance safe distributed caching (oplock), optional packet
++ signing, large files, Unicode support and other internationalization
++ improvements. Since both Samba server and this filesystem client support
++ the CIFS Unix extensions, the combination can provide a reasonable
++ alternative to NFSv4 for fileserving in some Linux to Linux environments,
++ not just in Linux to Windows environments.
++
++ This filesystem has an optional mount utility (mount.cifs) that can
++ be obtained from the project page and installed in the path in the same
++ directory with the other mount helpers (such as mount.smbfs).
++ Mounting using the cifs filesystem without installing the mount helper
++ requires specifying the server's ip address.
++
++ For Linux 2.4:
++ mount //anything/here /mnt_target -o
++ user=username,pass=password,unc=//ip_address_of_server/sharename
++
++ For Linux 2.5:
++ mount //ip_address_of_server/sharename /mnt_target -o user=username, pass=password
++
++
++ For more information on the module see the project page at

++Version 1.20
++------------
++Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
++info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
++(in build_wildcard_path_from_dentry). 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

++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 0.95
++------------
++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.

++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

++code (distributed caching) to properly send response to oplock
++break from server.
++
++Version 0.81

++presence or absence of read only dos attribute in mode
++bits for servers that do not support CIFS Unix extensions.
++Fix shortened results on readdir of large directories to
++servers supporting CIFS Unix extensions (caused by

++
++Version 0.73
++------------
++unload nls if mount fails.
++
++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.

++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,

++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 0.55
++------------
++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
++------------

++for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
++and CIFS Packet Signing enablement.
++
++Version 0.52
++------------

++------------
++Various big endian fixes for servers with Unix extensions such as Samba
++
++Version 0.43
++------------
++Various FindNext fixes for incorrect filenames on large directory searches on big endian
++clients. basic posix file i/o tests now work on big endian machines, not just le

++------------
++SessionSetup and NegotiateProtocol now work from Big Endian machines.
++Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older

++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

++Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
++
++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.
++

++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

++ For better POSIX semantics from Linux client, (even better
++ than the existing CIFS Unix Extensions) we need updated PDUs for:
++
++ 1) PosixCreateX - to set and return the mode, inode#, device info and
++ perhaps add a CreateDevice - to create Pipes and other special .inodes
++ Also note POSIX open flags
++ 2) Close - to return the last write time to do cache across close more safely
++ 3) PosixQFSInfo - to return statfs info
++ 4) FindFirst return unique inode number - what about resume key, two forms short (matches readdir) and full (enough info to cache inodes)
++ 5) Mkdir - set mode
++
++ And under consideration:
++ 6) FindClose2 (return nanosecond timestamp ??)
++ 7) Use nanosecond timestamps throughout all time fields if
++ corresponding attribute flag is set
++ 8) sendfile - handle based copy
++ 9) Direct i/o
++ 10) "POSIX ACL" support
++ 11) Misc fcntls?
++
++ what about fixing 64 bit alignment
++
++ There are also various legacy SMB/CIFS requests used as is
++
++ From existing Lanman and NTLM dialects:
++ --------------------------------------
++ NEGOTIATE
++ SESSION_SETUP_ANDX (BB which?)
++ TREE_CONNECT_ANDX (BB which wct?)
++ TREE_DISCONNECT (BB add volume timestamp on response)
++ LOGOFF_ANDX
++ DELETE (note delete open file behavior)
++ DELETE_DIRECTORY
++ READ_AND_X
++ WRITE_AND_X
++ LOCKING_AND_X (note posix lock semantics)
++ RENAME (note rename across dirs and open file rename posix behaviors)
++ NT_RENAME (for hardlinks) Is this good enough for all features?
++ FIND_CLOSE2
++ TRANSACTION2 (18 cases)
++ SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
++ (BB verify that never need to set allocation size)
++ SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via Unix ext?)
++
++ COPY (note support for copy across directories) - FUTURE, OPTIONAL
++ setting/getting OS/2 EAs - FUTURE (BB can this handle
++ setting Linux xattrs perfectly) - OPTIONAL
++ dnotify - FUTURE, OPTIONAL
++ quota - FUTURE, OPTIONAL
++
++ Note that various requests implemented for NT interop such as
++ NT_TRANSACT (IOCTL) QueryReparseInfo
++ are unneeded to servers compliant with the CIFS POSIX extensions
++
++ From CIFS Unix Extensions:
++ -------------------------
++ T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
++ T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
++ T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
++ T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) - BB check for missing inode fields
++ Actually need QUERY_FILE_UNIX_INFO since has inode num
++ BB what about a) blksize/blkbits/blocks
++ b) i_version
++ c) i_rdev
++ d) notify mask?
++ e) generation
++ f) size_seqcount
++ T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
++ TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
++ T2_QFS_INFO QueryDevice/AttributeInfo - OPTIONAL

++For Linux 2.4:
++1) Get the kernel source (e.g.from http://www.kernel.org)
++and download the cifs vfs source (see the project page
++at http://us1.samba.org/samba/Linux_CIFS_client.html)
++and change directory into the top of the kernel directory
++then patch the kernel (e.g. "patch -p1 < cifs_24.patch")
++to add the cifs vfs to your kernel configure options if
++it has not already been added (e.g. current SuSE and UL
++users do not need to apply the cifs_24.patch since the cifs vfs is
++already in the kernel configure menu) and then
++mkdir linux/fs/cifs and then copy the current cifs vfs files from
++the cifs download to your kernel build directory e.g.
++
++ cp <cifs_download_dir>/fs/cifs/* to <kernel_download_dir>/fs/cifs
++
++2) make menuconfig (or make xconfig)
++3) select cifs from within the network filesystem choices
++4) save and exit
++5) make dep
++6) make modules (or "make" if CIFS VFS not to be built as a module)
++
++For Linux 2.5:
++1) Download the kernel (e.g. from http://www.kernel.org or from bitkeeper
++at bk://linux.bkbits.net/linux-2.5) and change directory into the top
++of the kernel directory tree (e.g. /usr/src/linux-2.5.73)
++2) make menuconfig (or make xconfig)
++3) select cifs from within the network filesystem choices
++4) save and exit
++5) make
++
++
++Installation instructions:
++=========================
++If you have built the CIFS vfs as module (successfully) simply
++type "make modules_install" (or if you prefer, manually copy the file to
++the modules directory e.g. /lib/modules/2.4.10-4GB/kernel/fs/cifs/cifs.o).
++
++If you have built the CIFS vfs into the kernel itself, follow the instructions
++for your distribution on how to install a new kernel (usually you
++would simply type "make install").
++
++If you do not have the utility mount.cifs (in the Samba 3.0 source tree and on
++the CIFS VFS web site) copy it to the same directory in which mount.smbfs and
++similar files reside (usually /sbin). Although the helper software is not
++required, mount.cifs is recommended. Eventually the Samba 3.0 utility program
++"net" may also be helpful since it may someday provide easier mount syntax for
++users who are used to Windows e.g. net use <mount point> <UNC name or cifs URL>
++Note that running the Winbind pam/nss module (logon service) on all of your
++Linux clients is useful in mapping Uids and Gids consistently across the
++domain to the proper network user. The mount.cifs mount helper can be
++trivially built from Samba 3.0 or later source e.g. by executing:
++
++ gcc samba/source/client/mount.cifs.c -o mount.cifs
++
++Note that when the mount.cifs utility is run suid (allowing user mounts),
++in order to reduce risks, the "nosuid" mount flag is passed in on mount to
++disallow execution of an suid program mounted on the remote target.
++When mount is executed as root, nosuid is not passed in by default,
++and execution of suid programs on the remote target would be enabled
++by default. This can be changed, as with nfs and other filesystems,
++by simply specifying "nosuid" among the mount options. For user mounts
++though to be able to pass the suid flag to mount requires rebuilding
++mount.cifs with the following flag:
++
++ gcc samba/source/client/mount.cifs.c -DCIFS_ALLOW_USR_SUID -o mount.cifs
++
++There is a corresponding manual page for cifs mounting in the Samba 3.0 and
++later source tree in docs/manpages/mount.cifs.8
++
++Samba Considerations
++====================
++To get the maximum benefit from the CIFS VFS, we recommend using a server that
++supports the SNIA CIFS Unix Extensions standard (e.g. Samba 2.2.5 or later or
++Samba 3.0) but the CIFS vfs works fine with a wide variety of CIFS servers.
++Note that uid, gid and file permissions will display default values if you do
++not have a server that supports the Unix extensions for CIFS (such as Samba
++2.2.5 or later). 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. (default is 0)
++PacketSigningEnabled If set to one, cifs packet signing is enabled
++ and will be used if the server requires
++ it. If set to two, cifs packet signing is
++ required even if the server considers packet
++ signing optional. (default 1)
++cifsFYI If set to one, additional debug information is
++ logged to the system error log. (default 0)
++ExtendedSecurity If set to one, SPNEGO session establishment
++ is allowed which enables more advanced
++ secure CIFS session establishment (default 0)
++NTLMV2Enabled If set to one, more secure password hashes
++ are used when the server supports them and
++ when kerberos is not negotiated (default 0)
++traceSMB If set to one, debug information is logged to the
++ system error log with the start of smb requests
++ and responses (default 0)
++LookupCacheEnable If set to one, inode information is kept cached
++ for one second improving performance of lookups
++ (default 1)
++OplockEnabled If set to one, safe distributed caching enabled.
++ (default 1)
++LinuxExtensionsEnabled If set to one then the client will attempt to
++ use the CIFS "UNIX" extensions which are optional
++ protocol enhancements that allow CIFS servers
++ to return accurate UID/GID information as well
++ as support symbolic links. If you use servers
++ such as Samba that support the CIFS Unix
++ extensions but do not want to use symbolic link
++ support and want to map the uid and gid fields
++ to values supplied at mount (rather than the
++ actual values, then set this to zero. (default 1)
++
++These experimental features and tracing can be enabled by changing flags in
++/proc/fs/cifs (after the cifs module has been installed or built into the
++kernel, e.g. insmod cifs). To enable a feature set it to 1 e.g. to enable
++tracing to the kernel message log type:
++
++ echo 1 > /proc/fs/cifs/cifsFYI
++
++and for more extensive tracing including the start of smb requests and responses
++
++ echo 1 > /proc/fs/cifs/traceSMB
++
++Three other experimental features are under development and to test
++require enabling an ifdef (e.g. by adding "#define CIFS_FCNTL" in cifsglob.h)
++
++ CONFIG_CIFS_QUOTA
++
++ CONFIG_CIFS_XATTR
++
++ CONFIG_CIFS_FCNTL (fcntl needed for support of directory change
++ notification and perhaps later for file leases)
++
++Per share (per client mount) statistics are available in /proc/fs/cifs/DebugData
++if the kernel was configured with cifs statistics enabled. The statistics
++represent the number of successful (ie non-zero return code from the server)
++SMB responses to some of the more common commands (open, delete, mkdir etc.).
++Also recorded is the total bytes read and bytes written to the server for
++that share. Note that due to client caching effects this can be less than the
++number of bytes read and written by the application running on the client.
++The statistics for the number of total SMBs and oplock breaks are different in
++that they represent all for that share, not just those for which the server
++returned success.
++
++Also note that "cat /proc/fs/cifs/DebugData" will display information about
++the active sessions and the shares that are mounted. Note: NTLMv2 enablement
++will not work since they its implementation is not quite complete yet.
++Do not alter these configuration values unless you are doing specific testing.
++Enabling extended security works to Windows 2000 Workstations and XP but not to
++Windows 2000 server or Samba since it does not usually send "raw NTLMSSP"
++(instead it sends NTLMSSP encapsulated in SPNEGO/GSSAPI, which support is not
++complete in the CIFS VFS yet).

++
++A Partial List of Missing Features
++==================================
++
++Contributions are welcome. There are plenty of opportunities
++for visible, important contributions to this module. Here
++is a partial list of the known problems and missing features:
++
++a) Support for SecurityDescriptors for chmod/chgrp/chown so
++these can be supported for Windows servers
++
++b) Better pam/winbind integration
++
++c) multi-user mounts - multiplexed sessionsetups over single vc
++(ie tcp session) - prettying up needed
++
++d) Kerberos/SPNEGO session setup support - (started)
++
++e) NTLMv2 authentication (mostly implemented)
++
++f) MD5-HMAC signing SMB PDUs when SPNEGO style SessionSetup
++used (Kerberos or NTLMSSP). Signing alreadyimplemented for NTLM
++and raw NTLMSSP already. This is important when enabling
++extended security and mounting to Windows 2003 Servers
++
++f) Directory entry caching relies on a 1 second timer, rather than
++using FindNotify or equivalent. - (started)
++
++g) A few byte range testcases fail due to POSIX vs. Windows/CIFS
++style byte range lock differences
++
++h) quota support
++
++i) support for the Linux 2.5 kernel new feature get_xattr and set_xattr
++which will allow us to expose dos attributes as well as real
++ACLs. This support has been started in the current code, but is
++ifdeffed out.
++
++k) finish writepages support (multi-page write behind for improved
++performance) and syncpage
++
++l) hook lower into the sockets api (as NFS/SunRPC does) to avoid the
++extra copy in/out of the socket buffers in some cases.
++
++m) finish support for IPv6. This is mostly complete but
++needs a simple inet_pton like function to convert ipv6
++addresses in string representation.
++
++o) Better optimize open (and pathbased setfilesize) to reduce the
++oplock breaks coming from windows srv. Piggyback identical file
++opens on top of each other by incrementing reference count rather
++than resending (helps reduce server resource utilization and avoid
++spurious oplock breaks).
++
++p) Improve performance of readpages by sending more than one read
++at a time when 8 pages or more are requested. Evaluate whether
++reads larger than 16K would be helpful.
++
++q) For support of Windows9x/98 we need to retry failed mounts
++to *SMBSERVER (default server name) with the uppercase hostname
++in the RFC1001 session_init request.
++
++r) Add Extended Attributed support (for storing UID/GID info
++to Windows servers)
++
++s) Finish fcntl D_NOTIFY support so kde and gnome file list windows
++will autorefresh
++
++t) Add GUI tool to configure /proc/fs/cifs settings and for display of
++the CIFS statistics
++
++KNOWN BUGS (updated May 27, 2004)
++====================================
++1) existing symbolic links (Windows reparse points) are recognized but
++can not be created remotely. They are implemented for Samba and those that
++support the CIFS Unix extensions but Samba has a bug currently handling
++symlink text beginning with slash
++2) follow_link and readdir code does not follow dfs junctions
++but recognizes them
++3) create of new files to FAT partitions on Windows servers can
++succeed but still return access denied (appears to be Windows
++server not cifs client problem) and has not been reproduced recently.
++NTFS partitions do not have this problem.
++4) debug connectathon lock test case 10 which fails against
++Samba (may be unmappable due to POSIX to Windows lock model
++differences but worth investigating). Also debug Samba to
++see why lock test case 7 takes longer to complete to Samba
++than to Windows.
++
++Misc testing to do
++==================
++1) check out max path names and max path name components against various server
++types. Try nested symlinks. Return max path name in stat -f information
++
++2) Modify file portion of ltp so it can run against a mounted network
++share and run it against cifs vfs.
++
++3) Additional performance testing and optimization using iozone and similar -
++there are some easy changes that can be done to parallelize sequential writes,
++and when signing is disabled to request larger read sizes (larger than
++negotiated size) and send larger write sizes to modern servers.
++
++4) More exhaustively test the recently added NT4 support against various
++NT4 service pack levels.
