+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
|

+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

+ (SMB) protocol, the native file sharing mechanism for most early
|

|
+ 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
|

|
+The IBM Linux JFS team for explaining many esoteric Linux filesystem features.
|
|
+Dave Boutcher of IBM Rochester (author of the OS/400 smb/cifs filesystem client)
|

|
+operating system. Volker Lendecke, Andrew Tridgell, Urban Widmark, John Newbigin
|
|
+and others for their work on the Linux smbfs module over the years. Thanks to
|
|
+the other members of the Storage Network Industry Association CIFS Technical

|
|
+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
|
|
+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

|
+shares to the same Windows server when using different usernames

+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

|
|
+ 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

|
|
+The CIFS VFS support for Linux supports many advanced network filesystem
|
|
+features such as heirarchical dfs like namespace, hardlinks, locking and more.
|
|
+It was designed to comply with the SNIA CIFS Technical Reference (which
|
|
+supersedes the 1992 X/Open SMB Standard) as well as to perform best practice
|
|
+practical interoperability with Windows 2000, Windows XP, Samba and equivalent
|
|
+servers.
|
|
+
|
|
+For questions or bug reports please contact:
|
|
+ sfrench@samba.org (sfrench@us.ibm.com)
|
|
+
|
|
+Build instructions:
|
|
+==================
|
|
+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).

|
|
+ This code makes no attempt to be fast! In fact, it is a very

|
|
+
|
|
+ This code is NOT a complete DES implementation. It implements only
|
|
+ the minimum necessary for SMB authentication, as used by all SMB
|
|
+ products (including every copy of Microsoft Windows95 ever sold)
|

|
|
+
|
|
+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.
