Original Author
===============
Steve French (sfrench@samba.org)
The author wishes to express his appreciation and thanks to:
Andrew Tridgell (Samba team) for his early suggestions about smb/cifs VFS
improvements. Thanks to IBM for allowing me time and test resources to pursue
this project, to Jim McDonough from IBM (and the Samba Team) for his help, to
the IBM Linux JFS team for explaining many esoteric Linux filesystem features.
Jeremy Allison of the Samba team has done invaluable work in adding the server
side of the original CIFS Unix extensions and reviewing and implementing
portions of the newer CIFS POSIX extensions into the Samba 3 file server. Thank
Dave Boutcher of IBM Rochester (author of the OS/400 smb/cifs filesystem client)
for proving years ago that very good smb/cifs clients could be done on Unix-like
operating systems. Volker Lendecke, Andrew Tridgell, Urban Widmark, John
Newbigin and others for their work on the Linux smbfs module. Thanks to
the other members of the Storage Network Industry Association CIFS Technical
Workgroup for their work specifying this highly complex protocol and finally
thanks to the Samba team for their technical advice and encouragement.

config CIFS
tristate "CIFS support (advanced network filesystem, SMBFS successor)"
depends on INET
select NLS
select SLOW_WORK
help
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. The CIFS protocol is fully supported by
file servers such as Windows 2000 (including Windows 2003, NT 4
and Windows XP) as well by Samba (which provides excellent CIFS
server support for Linux and many other operating systems). Limited
support for OS/2 and Windows ME and similar servers is provided as
well.
The cifs module provides an advanced network file system
client for mounting to CIFS compliant servers. It includes
support for DFS (hierarchical name space), secure per-user
session establishment via Kerberos or NTLM or NTLMv2,
safe distributed caching (oplock), optional packet
signing, Unicode and other internationalization improvements.
If you need to mount to Samba or Windows from this machine, say Y.
config CIFS_STATS
bool "CIFS statistics"
depends on CIFS
help
Enabling this option will cause statistics for each server share
mounted by the cifs client to be displayed in /proc/fs/cifs/Stats
config CIFS_STATS2
bool "Extended statistics"
depends on CIFS_STATS
help
Enabling this option will allow more detailed statistics on SMB
request timing to be displayed in /proc/fs/cifs/DebugData and also
allow optional logging of slow responses to dmesg (depending on the
value of /proc/fs/cifs/cifsFYI, see fs/cifs/README for more details).
These additional statistics may have a minor effect on performance
and memory utilization.
Unless you are a developer or are doing network performance analysis
or tuning, say N.
config CIFS_WEAK_PW_HASH
bool "Support legacy servers which use weaker LANMAN security"
depends on CIFS
help
Modern CIFS servers including Samba and most Windows versions
(since 1997) support stronger NTLM (and even NTLMv2 and Kerberos)
security mechanisms. These hash the password more securely
than the mechanisms used in the older LANMAN version of the
SMB protocol but LANMAN based authentication is needed to
establish sessions with some old SMB servers.
Enabling this option allows the cifs module to mount to older
LANMAN based servers such as OS/2 and Windows 95, but such
mounts may be less secure than mounts using NTLM or more recent
security mechanisms if you are on a public network. Unless you
have a need to access old SMB servers (and are on a private
network) you probably want to say N. Even if this support
is enabled in the kernel build, LANMAN authentication will not be
used automatically. At runtime LANMAN mounts are disabled but
can be set to required (or optional) either in
/proc/fs/cifs (see fs/cifs/README for more detail) or via an
option on the mount command. This support is disabled by
default in order to reduce the possibility of a downgrade
attack.
If unsure, say N.
config CIFS_UPCALL
bool "Kerberos/SPNEGO advanced session setup"
depends on CIFS && KEYS
help
Enables an upcall mechanism for CIFS which accesses
userspace helper utilities to provide SPNEGO packaged (RFC 4178)
Kerberos tickets which are needed to mount to certain secure servers
(for which more secure Kerberos authentication is required). If
unsure, say N.
config CIFS_XATTR
bool "CIFS extended attributes"
depends on CIFS
help
Extended attributes are name:value pairs associated with inodes by
the kernel or by users (see the attr(5) manual page, or visit
<http://acl.bestbits.at/> for details). CIFS maps the name of
extended attributes beginning with the user namespace prefix
to SMB/CIFS EAs. EAs are stored on Windows servers without the
user namespace prefix, but their names are seen by Linux cifs clients
prefaced by the user namespace prefix. The system namespace
(used by some filesystems to store ACLs) is not supported at
this time.
If unsure, say N.
config CIFS_POSIX
bool "CIFS POSIX Extensions"
depends on CIFS_XATTR
help
Enabling this option will cause the cifs client to attempt to
negotiate a newer dialect with servers, such as Samba 3.0.5
or later, that optionally can handle more POSIX like (rather
than Windows like) file behavior. It also enables
support for POSIX ACLs (getfacl and setfacl) to servers
(such as Samba 3.10 and later) which can negotiate
CIFS POSIX ACL support. If unsure, say N.
config CIFS_DEBUG2
bool "Enable additional CIFS debugging routines"
depends on CIFS
help
Enabling this option adds a few more debugging routines
to the cifs code which slightly increases the size of
the cifs module and can cause additional logging of debug
messages in some error paths, slowing performance. This
option can be turned off unless you are debugging
cifs problems. If unsure, say N.
config CIFS_DFS_UPCALL
bool "DFS feature support"
depends on CIFS && KEYS
help
Distributed File System (DFS) support is used to access shares
transparently in an enterprise name space, even if the share
moves to a different server. This feature also enables
an upcall mechanism for CIFS which contacts userspace helper
utilities to provide server name resolution (host names to
IP addresses) which is needed for implicit mounts of DFS junction
points. If unsure, say N.
config CIFS_EXPERIMENTAL
bool "CIFS Experimental Features (EXPERIMENTAL)"
depends on CIFS && EXPERIMENTAL
help
Enables cifs features under testing. These features are
experimental and currently include DFS support and directory
change notification ie fcntl(F_DNOTIFY), as well as the upcall
mechanism which will be used for Kerberos session negotiation
and uid remapping. Some of these features also may depend on
setting a value of 1 to the pseudo-file /proc/fs/cifs/Experimental
(which is disabled by default). See the file fs/cifs/README
for more details. If unsure, say N.

The CIFS VFS support for Linux supports many advanced network filesystem
features such as hierarchical 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. This code was developed in participation with the Protocol Freedom
Information Foundation.

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 2.6:
1) Download the kernel (e.g. from http://www.kernel.org)
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
If cifs is built as a module, then the size and number of network buffers
and maximum number of simultaneous requests to one server can be configured.
Changing these from their defaults is not recommended. By executing modinfo
modinfo kernel/fs/cifs/cifs.ko
on kernel/fs/cifs/cifs.ko the list of configuration changes that can be made
at module initialization time (by running insmod cifs.ko) can be seen.
Allowing User Mounts
====================
To permit users to mount and unmount over directories they own is possible
with the cifs vfs. A way to enable such mounting is to mark the mount.cifs
utility as suid (e.g. "chmod +s /sbin/mount.cifs). To enable users to
umount shares they mount requires
1) mount.cifs version 1.4 or later
2) an entry for the share in /etc/fstab indicating that a user may
unmount it e.g.
//server/usersharename /mnt/username cifs user 0 0
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
Allowing User Unmounts
======================
To permit users to ummount directories that they have user mounted (see above),
the utility umount.cifs may be used. It may be invoked directly, or if
umount.cifs is placed in /sbin, umount can invoke the cifs umount helper
(at least for most versions of the umount utility) for umount of cifs
mounts, unless umount is invoked with -i (which will avoid invoking a umount
helper). As with mount.cifs, to enable user unmounts umount.cifs must be marked
as suid (e.g. "chmod +s /sbin/umount.cifs") or equivalent (some distributions
allow adding entries to a file to the /etc/permissions file to achieve the
equivalent suid effect). For this utility to succeed the target path
must be a cifs mount, and the uid of the current user must match the uid
of the user who mounted the resource.
Also note that the customary way of allowing user mounts and unmounts is
(instead of using mount.cifs and unmount.cifs as suid) to add a line
to the file /etc/fstab for each //server/share you wish to mount, but
this can become unwieldy when potential mount targets include many
or unpredictable UNC names.
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 server ea support is required for supporting xattrs from the Linux
cifs client, and that EA support is present in later versions of Samba (e.g.
3.0.6 and later (also EA support works in all versions of Windows, at least to
shares on NTFS filesystems). Extended Attribute (xattr) support is an optional
feature of most Linux filesystems which may require enabling via
make menuconfig. Client support for extended attributes (user xattr) can be
disabled on a per-mount basis by specifying "nouser_xattr" on mount.
The CIFS client can get and set POSIX ACLs (getfacl, setfacl) to Samba servers
version 3.10 and later. Setting POSIX ACLs requires enabling both XATTR and
then POSIX support in the CIFS configuration options when building the cifs
module. POSIX ACL support can be disabled on a per mount basic by specifying
"noacl" on mount.
Some administrators may want to change Samba's smb.conf "map archive" and
"create mask" parameters from the default. Unless the create mask is changed
newly created files can end up with an unnecessarily restrictive default mode,
which may not be what you want, although if the CIFS Unix extensions are
enabled on the server and client, subsequent setattr calls (e.g. chmod) can
fix the mode. Note that creating special devices (mknod) remotely
may require specifying a mkdev function to Samba if you are not using
Samba 3.0.6 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 3.0.6, most symlinks to
files with absolute paths (ie beginning with slash) such as:
ln -s /mnt/foo bar
would be forbidden. Samba 3.0.6 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).
Although mounting using format corresponding to the CIFS URL specification is
not possible in mount.cifs yet, it is possible to use an alternate format
for the server and sharename (which is somewhat similar to NFS style mount
syntax) instead of the more widely used UNC format (i.e. \\server\share):
mount -t cifs tcp_name_of_server:share_name /mnt -o user=myname,pass=mypasswd
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 either "pure-TCP" (port 445 TCP/IP CIFS connections) or RFC
1001/1002 support for "Netbios-Over-TCP/IP." This is not likely to be a
problem as most servers support this.
Valid filenames differ between Windows and Linux. Windows typically restricts
filenames which contain certain reserved characters (e.g.the character :
which is used to delimit the beginning of a stream name by Windows), while
Linux allows a slightly wider set of valid characters in filenames. Windows
servers can remap such characters when an explicit mapping is specified in
the Server's registry. Samba starting with version 3.10 will allow such
filenames (ie those which contain valid Linux characters, which normally
would be forbidden for Windows/CIFS semantics) as long as the server is
configured for Unix Extensions (and the client has not disabled
/proc/fs/cifs/LinuxExtensionsEnabled).
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 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
forceuid Set the default uid for inodes to the uid
passed in on mount. 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 so this parameter should not be
specified unless the server and clients uid and gid
numbering differ. If the server and client are in the
same domain (e.g. running winbind or nss_ldap) and
the server supports the Unix Extensions then the uid
and gid can be retrieved from the server (and uid
and gid would not have to be specifed on the mount.
For servers which do not support the CIFS Unix
extensions, the default uid (and gid) returned on lookup
of existing files will be 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. 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. (default)
forcegid (similar to above but for the groupid instead of uid) (default)
noforceuid Fill in file owner information (uid) by requesting it from
the server if possible. With this option, the value given in
the uid= option (on mount) will only be used if the server
can not support returning uids on inodes.
noforcegid (similar to above but for the group owner, gid, instead of uid)
uid Set the default uid for inodes, and indicate to the
cifs kernel driver which local user mounted. If the server
supports the unix extensions the default uid is
not used to fill in the owner fields of inodes (files)
unless the "forceuid" parameter is specified.
gid Set the default gid for inodes (similar to above).
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 (usually 16K). The client currently
can not use rsize larger than CIFSMaxBufSize. CIFSMaxBufSize
defaults to 16K and may be changed (from 8K to the maximum
kmalloc size allowed by your kernel) at module install time
for cifs.ko. Setting CIFSMaxBufSize to a very large value
will cause cifs to use more memory and may reduce performance
in some cases. To use rsize greater than 127K (the original
cifs protocol maximum) also requires that the server support
a new Unix Capability flag (for very large read) which some
newer servers (e.g. Samba 3.0.26 or later) do. rsize can be
set from a minimum of 2048 to a maximum of 130048 (127K or
CIFSMaxBufSize, whichever is smaller)
wsize default write size (default 57344)
maximum wsize currently allowed by CIFS is 57344 (fourteen
4096 byte pages)
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.
exec Permit execution of binaries on the mount.
noexec Do not permit execution of binaries on the mount.
dev Recognize block devices on the remote mount.
nodev Do not recognize devices on the remote mount.
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.
perm Client does permission checks (vfs_permission check of uid
and gid of the file against the mode and desired operation),
Note that this is in addition to the normal ACL check on the
target machine done by the server software.
Client permission checking is enabled by default.
noperm Client does not do permission checks. This can expose
files on this mount to access by other users on the local
client system. It is typically only needed when the server
supports the CIFS Unix Extensions but the UIDs/GIDs on the
client and server system do not match closely enough to allow
access by the user doing the mount, but it may be useful with
non CIFS Unix Extension mounts for cases in which the default
mode is specified on the mount but is not to be enforced on the
client (e.g. perhaps when MultiUserMount is enabled)
Note that this does not affect the normal ACL check on the
target machine done by the server software (of the server
ACL against the user name provided at mount time).
serverino Use server's inode numbers instead of generating automatically
incrementing inode numbers on the client. Although this will
make it easier to spot hardlinked files (as they will have
the same inode numbers) and inode numbers may be persistent,
note that the server does not guarantee that the inode numbers
are unique if multiple server side mounts are exported under a
single share (since inode numbers on the servers might not
be unique if multiple filesystems are mounted under the same
shared higher level directory). Note that some older
(e.g. pre-Windows 2000) do not support returning UniqueIDs
or the CIFS Unix Extensions equivalent and for those
this mount option will have no effect. Exporting cifs mounts
under nfsd requires this mount option on the cifs mount.
This is now the default if server supports the
required network operation.
noserverino Client generates inode numbers (rather than using the actual one
from the server). These inode numbers will vary after
unmount or reboot which can confuse some applications,
but not all server filesystems support unique inode
numbers.
setuids If the CIFS Unix extensions are negotiated with the server
the client will attempt to set the effective uid and gid of
the local process on newly created files, directories, and
devices (create, mkdir, mknod). If the CIFS Unix Extensions
are not negotiated, for newly created files and directories
instead of using the default uid and gid specified on
the mount, cache the new file's uid and gid locally which means
that the uid for the file can change when the inode is
reloaded (or the user remounts the share).
nosetuids The client will not attempt to set the uid and gid on
on newly created files, directories, and devices (create,
mkdir, mknod) which will result in the server setting the
uid and gid to the default (usually the server uid of the
user who mounted the share). Letting the server (rather than
the client) set the uid and gid is the default. If the CIFS
Unix Extensions are not negotiated then the uid and gid for
new files will appear to be the uid (gid) of the mounter or the
uid (gid) parameter specified on the mount.
netbiosname When mounting to servers via port 139, specifies the RFC1001
source name to use to represent the client netbios machine
name when doing the RFC1001 netbios session initialize.
direct Do not do inode data caching on files opened on this mount.
This precludes mmaping files on this mount. In some cases
with fast networks and little or no caching benefits on the
client (e.g. when the application is doing large sequential
reads bigger than page size without rereading the same data)
this can provide better performance than the default
behavior which caches reads (readahead) and writes
(writebehind) through the local Linux client pagecache
if oplock (caching token) is granted and held. Note that
direct allows write operations larger than page size
to be sent to the server.
acl Allow setfacl and getfacl to manage posix ACLs if server
supports them. (default)
noacl Do not allow setfacl and getfacl calls on this mount
user_xattr Allow getting and setting user xattrs (those attributes whose
name begins with "user." or "os2.") as OS/2 EAs (extended
attributes) to the server. This allows support of the
setfattr and getfattr utilities. (default)
nouser_xattr Do not allow getfattr/setfattr to get/set/list xattrs
mapchars Translate six of the seven reserved characters (not backslash)
*?<>|:
to the remap range (above 0xF000), which also
allows the CIFS client to recognize files created with
such characters by Windows's POSIX emulation. This can
also be useful when mounting to most versions of Samba
(which also forbids creating and opening files
whose names contain any of these seven characters).
This has no effect if the server does not support
Unicode on the wire.
nomapchars Do not translate any of these seven characters (default).
nocase Request case insensitive path name matching (case
sensitive is the default if the server suports it).
(mount option "ignorecase" is identical to "nocase")
posixpaths If CIFS Unix extensions are supported, attempt to
negotiate posix path name support which allows certain
characters forbidden in typical CIFS filenames, without
requiring remapping. (default)
noposixpaths If CIFS Unix extensions are supported, do not request
posix path name support (this may cause servers to
reject creatingfile with certain reserved characters).
nounix Disable the CIFS Unix Extensions for this mount (tree
connection). This is rarely needed, but it may be useful
in order to turn off multiple settings all at once (ie
posix acls, posix locks, posix paths, symlink support
and retrieving uids/gids/mode from the server) or to
work around a bug in server which implement the Unix
Extensions.
nobrl Do not send byte range lock requests to the server.
This is necessary for certain applications that break
with cifs style mandatory byte range locks (and most
cifs servers do not yet support requesting advisory
byte range locks).
forcemandatorylock Even if the server supports posix (advisory) byte range
locking, send only mandatory lock requests. For some
(presumably rare) applications, originally coded for
DOS/Windows, which require Windows style mandatory byte range
locking, they may be able to take advantage of this option,
forcing the cifs client to only send mandatory locks
even if the cifs server would support posix advisory locks.
"forcemand" is accepted as a shorter form of this mount
option.
nostrictsync If this mount option is set, when an application does an
fsync call then the cifs client does not send an SMB Flush
to the server (to force the server to write all dirty data
for this file immediately to disk), although cifs still sends
all dirty (cached) file data to the server and waits for the
server to respond to the write. Since SMB Flush can be
very slow, and some servers may be reliable enough (to risk
delaying slightly flushing the data to disk on the server),
turning on this option may be useful to improve performance for
applications that fsync too much, at a small risk of server
crash. If this mount option is not set, by default cifs will
send an SMB flush request (and wait for a response) on every
fsync call.
nodfs Disable DFS (global name space support) even if the
server claims to support it. This can help work around
a problem with parsing of DFS paths with Samba server
versions 3.0.24 and 3.0.25.
remount remount the share (often used to change from ro to rw mounts
or vice versa)
cifsacl Report mode bits (e.g. on stat) based on the Windows ACL for
the file. (EXPERIMENTAL)
servern Specify the server 's netbios name (RFC1001 name) to use
when attempting to setup a session to the server.
This is needed for mounting to some older servers (such
as OS/2 or Windows 98 and Windows ME) since they do not
support a default server name. A server name can be up
to 15 characters long and is usually uppercased.
sfu When the CIFS Unix Extensions are not negotiated, attempt to
create device files and fifos in a format compatible with
Services for Unix (SFU). In addition retrieve bits 10-12
of the mode via the SETFILEBITS extended attribute (as
SFU does). In the future the bottom 9 bits of the
mode also will be emulated using queries of the security
descriptor (ACL).
sign Must use packet signing (helps avoid unwanted data modification
by intermediate systems in the route). Note that signing
does not work with lanman or plaintext authentication.
seal Must seal (encrypt) all data on this mounted share before
sending on the network. Requires support for Unix Extensions.
Note that this differs from the sign mount option in that it
causes encryption of data sent over this mounted share but other
shares mounted to the same server are unaffected.
locallease This option is rarely needed. Fcntl F_SETLEASE is
used by some applications such as Samba and NFSv4 server to
check to see whether a file is cacheable. CIFS has no way
to explicitly request a lease, but can check whether a file
is cacheable (oplocked). Unfortunately, even if a file
is not oplocked, it could still be cacheable (ie cifs client
could grant fcntl leases if no other local processes are using
the file) for cases for example such as when the server does not
support oplocks and the user is sure that the only updates to
the file will be from this client. Specifying this mount option
will allow the cifs client to check for leases (only) locally
for files which are not oplocked instead of denying leases
in that case. (EXPERIMENTAL)
sec Security mode. Allowed values are:
none attempt to connection as a null user (no name)
krb5 Use Kerberos version 5 authentication
krb5i Use Kerberos authentication and packet signing
ntlm Use NTLM password hashing (default)
ntlmi Use NTLM password hashing with signing (if
/proc/fs/cifs/PacketSigningEnabled on or if
server requires signing also can be the default)
ntlmv2 Use NTLMv2 password hashing
ntlmv2i Use NTLMv2 password hashing with packet signing
lanman (if configured in kernel config) use older
lanman hash
hard Retry file operations if server is not responding
soft Limit retries to unresponsive servers (usually only
one retry) before returning an error. (default)
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 most 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, as well as the cifs.ko version.
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)
SecurityFlags Flags which control security negotiation and
also packet signing. Authentication (may/must)
flags (e.g. for NTLM and/or NTLMv2) may be combined with
the signing flags. Specifying two different password
hashing mechanisms (as "must use") on the other hand
does not make much sense. Default flags are
0x07007
(NTLM, NTLMv2 and packet signing allowed). The maximum
allowable flags if you want to allow mounts to servers
using weaker password hashes is 0x37037 (lanman,
plaintext, ntlm, ntlmv2, signing allowed). Some
SecurityFlags require the corresponding menuconfig
options to be enabled (lanman and plaintext require
CONFIG_CIFS_WEAK_PW_HASH for example). Enabling
plaintext authentication currently requires also
enabling lanman authentication in the security flags
because the cifs module only supports sending
laintext passwords using the older lanman dialect
form of the session setup SMB. (e.g. for authentication
using plain text passwords, set the SecurityFlags
to 0x30030):
may use packet signing 0x00001
must use packet signing 0x01001
may use NTLM (most common password hash) 0x00002
must use NTLM 0x02002
may use NTLMv2 0x00004
must use NTLMv2 0x04004
may use Kerberos security 0x00008
must use Kerberos 0x08008
may use lanman (weak) password hash 0x00010
must use lanman password hash 0x10010
may use plaintext passwords 0x00020
must use plaintext passwords 0x20020
(reserved for future packet encryption) 0x00040
cifsFYI If set to non-zero value, additional debug information
will be logged to the system error log. This field
contains three flags controlling different classes of
debugging entries. The maximum value it can be set
to is 7 which enables all debugging points (default 0).
Some debugging statements are not compiled into the
cifs kernel unless CONFIG_CIFS_DEBUG2 is enabled in the
kernel configuration. cifsFYI may be set to one or
nore of the following flags (7 sets them all):
log cifs informational messages 0x01
log return codes from cifs entry points 0x02
log slow responses (ie which take longer than 1 second)
CONFIG_CIFS_STATS2 must be enabled in .config 0x04
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)
Experimental When set to 1 used to enable certain experimental
features (currently enables multipage writes
when signing is enabled, the multipage write
performance enhancement was disabled when
signing turned on in case buffer was modified
just before it was sent, also this flag will
be used to use the new experimental directory change
notification code). When set to 2 enables
an additional experimental feature, "raw ntlmssp"
session establishment support (which allows
specifying "sec=ntlmssp" on mount). The Linux cifs
module will use ntlmv2 authentication encapsulated
in "raw ntlmssp" (not using SPNEGO) when
"sec=ntlmssp" is specified on mount.
This support also requires building cifs with
the CONFIG_CIFS_EXPERIMENTAL configuration flag.
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 7 > /proc/fs/cifs/cifsFYI
cifsFYI functions as a bit mask. Setting it to 1 enables additional kernel
logging of various informational messages. 2 enables logging of non-zero
SMB return codes while 4 enables logging of requests that take longer
than one second to complete (except for byte range lock requests).
Setting it to 4 requires defining CONFIG_CIFS_STATS2 manually in the
source code (typically by setting it in the beginning of cifsglob.h),
and setting it to seven enables all three. Finally, tracing
the start of smb requests and responses can be enabled via:
echo 1 > /proc/fs/cifs/traceSMB
Two other experimental features are under development. To test these
requires enabling CONFIG_CIFS_EXPERIMENTAL
cifsacl support needed to retrieve approximated mode bits based on
the contents on the CIFS ACL.
lease support: cifs will check the oplock state before calling into
the vfs to see if we can grant a lease on a file.
DNOTIFY 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/Stats
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.
Enabling Kerberos (extended security) works but requires version 1.2 or later
of the helper program cifs.upcall to be present and to be configured in the
/etc/request-key.conf file. The cifs.upcall helper program is from the Samba
project(http://www.samba.org). NTLM and NTLMv2 and LANMAN support do not
require this helper. Note that NTLMv2 security (which does not require the
cifs.upcall helper program), instead of using Kerberos, is sufficient for
some use cases.
DFS support allows transparent redirection to shares in an MS-DFS name space.
In addition, DFS support for target shares which are specified as UNC
names which begin with host names (rather than IP addresses) requires
a user space helper (such as cifs.upcall) to be present in order to
translate host names to ip address, and the user space helper must also
be configured in the file /etc/request-key.conf. Samba, Windows servers and
many NAS appliances support DFS as a way of constructing a global name
space to ease network configuration and improve reliability.
To use cifs Kerberos and DFS support, the Linux keyutils package should be
installed and something like the following lines should be added to the
/etc/request-key.conf file:
create cifs.spnego * * /usr/local/sbin/cifs.upcall %k
create dns_resolver * * /usr/local/sbin/cifs.upcall %k

Version 1.53 May 20, 2008
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(Windows/CIFS ACLs) for chmod/chgrp/chown
so that these operations can be supported to Windows servers
b) Mapping POSIX ACLs (and eventually NFSv4 ACLs) to CIFS
SecurityDescriptors
c) Better pam/winbind integration (e.g. to handle uid mapping
better)
d) Cleanup now unneeded SessSetup code in
fs/cifs/connect.c and add back in NTLMSSP code if any servers
need it
e) fix NTLMv2 signing when two mounts with different users to same
server.
f) Directory entry caching relies on a 1 second timer, rather than
using FindNotify or equivalent. - (started)
g) quota support (needs minor kernel change since quota calls
to make it to network filesystems or deviceless filesystems)
h) investigate sync behavior (including syncpage) and check
for proper behavior of intr/nointr
i) improve support for very old servers (OS/2 and Win9x for example)
Including support for changing the time remotely (utimes command).
j) hook lower into the sockets api (as NFS/SunRPC does) to avoid the
extra copy in/out of the socket buffers in some cases.
k) 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).
l) Improve performance of readpages by sending more than one read
at a time when 8 pages or more are requested. In conjuntion
add support for async_cifs_readpages.
m) Add support for storing symlink info to Windows servers
in the Extended Attribute format their SFU clients would recognize.
n) Finish fcntl D_NOTIFY support so kde and gnome file list windows
will autorefresh (partially complete by Asser). Needs minor kernel
vfs change to support removing D_NOTIFY on a file.
o) Add GUI tool to configure /proc/fs/cifs settings and for display of
the CIFS statistics (started)
p) implement support for security and trusted categories of xattrs
(requires minor protocol extension) to enable better support for SELINUX
q) Implement O_DIRECT flag on open (already supported on mount)
r) Create UID mapping facility so server UIDs can be mapped on a per
mount or a per server basis to client UIDs or nobody if no mapping
exists. This is helpful when Unix extensions are negotiated to
allow better permission checking when UIDs differ on the server
and client. Add new protocol request to the CIFS protocol
standard for asking the server for the corresponding name of a
particular uid.
s) Add support for CIFS Unix and also the newer POSIX extensions to the
server side for Samba 4.
t) In support for OS/2 (LANMAN 1.2 and LANMAN2.1 based SMB servers)
need to add ability to set time to server (utimes command)
u) DOS attrs - returned as pseudo-xattr in Samba format (check VFAT and NTFS for this too)
v) mount check for unmatched uids
w) Add support for new vfs entry points for setlease and fallocate
x) Fix Samba 3 server to handle Linux kernel aio so dbench with lots of
processes can proceed better in parallel (on the server)
y) Fix Samba 3 to handle reads/writes over 127K (and remove the cifs mount
restriction of wsize max being 127K)
KNOWN BUGS (updated April 24, 2007)
====================================
See http://bugzilla.samba.org - search on product "CifsVFS" for
current bug list.
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, although earlier versions of Samba
overly restrict the pathnames.
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) Unix/POSIX capabilities are reset after reconnection, and affect
a few fields in the tree connection but we do do not know which
superblocks to apply these changes to. We should probably walk
the list of superblocks to set these. Also need to check the
flags on the second mount to the same share, and see if we
can do the same trick that NFS does to remount duplicate shares.
Misc testing to do
==================
1) check out max path names and max path name components against various server
types. Try nested symlinks (8 deep). 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 in automated fashion.
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 against less common servers. More testing
against Windows 9x, Windows ME servers.

Find a free multiplex id (SMB mid). Otherwise there could be

wrong response to this request. Multiplex ids could collide if
one of a series requests takes much longer than the others, or
if a very large number of long lived requests (byte range
locks or FindNotify requests) are pending. No more than
64K-1 requests can be outstanding at one time. If no
mids are available, return zero. A future optimization
could make the combination of mids and uid the key we use
to demultiplex on (rather than mid alone).
In addition to the above check, the cifs demultiplex
code already used the command code as a secondary
check of the frame and if signing is negotiated the
response would be discarded if the mid were the same
but the signature was wrong. Since the mid is not put in the
pending queue until later (when it is about to be dispatched)
we do have to limit the number of outstanding requests
to somewhat less than 64K-1 although it is hard to imagine
so many threads being in the vfs at one time.

/* NOTES:
This code makes no attempt to be fast! In fact, it is a very
slow implementation
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)
In particular, it can only do a unchained forward DES pass. This
means it is not possible to use this code for encryption/decryption
of data, instead it is only useful as a "hash" algorithm.
There is no entry point into this code that allows normal DES operation.
I believe this means that this code does not come under ITAR
regulations but this is NOT a legal opinion. If you are concerned
about the applicability of ITAR regulations to this code then you
should confirm it for yourself (and maybe let me know if you come
up with a different answer to the one above)
