	select NLS

	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

        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

	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.

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_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.
