1920 help
1921 This is the client VFS module for the Common Internet File System
1922 (CIFS) protocol which is the successor to the Server Message Block
1923 (SMB) protocol, the native file sharing mechanism for most early
1924 PC operating systems. The CIFS protocol is fully supported by
1925 file servers such as Windows 2000 (including Windows 2003, NT 4
1926 and Windows XP) as well by Samba (which provides excellent CIFS
1927 server support for Linux and many other operating systems). Limited
1928 support for OS/2 and Windows ME and similar servers is provided as
1929 well.
1930
1931 The cifs module provides an advanced network file system
1932 client for mounting to CIFS compliant servers. It includes
1933 support for DFS (hierarchical name space), secure per-user
1934 session establishment via Kerberos or NTLM or NTLMv2,
1935 safe distributed caching (oplock), optional packet
1936 signing, Unicode and other internationalization improvements.
1937 If you need to mount to Samba or Windows from this machine, say Y.

1939config CIFS_STATS
1940 bool "CIFS statistics"
1941 depends on CIFS
1942 help
1943 Enabling this option will cause statistics for each server share
1944 mounted by the cifs client to be displayed in /proc/fs/cifs/Stats
1945
1946config CIFS_STATS2
1947 bool "Extended statistics"
1948 depends on CIFS_STATS
1949 help
1950 Enabling this option will allow more detailed statistics on SMB
1951 request timing to be displayed in /proc/fs/cifs/DebugData and also
1952 allow optional logging of slow responses to dmesg (depending on the
1953 value of /proc/fs/cifs/cifsFYI, see fs/cifs/README for more details).
1954 These additional statistics may have a minor effect on performance
1955 and memory utilization.
1956
1957 Unless you are a developer or are doing network performance analysis
1958 or tuning, say N.

1960config CIFS_WEAK_PW_HASH
1961 bool "Support legacy servers which use weaker LANMAN security"
1962 depends on CIFS
1963 help
1964 Modern CIFS servers including Samba and most Windows versions
1965 (since 1997) support stronger NTLM (and even NTLMv2 and Kerberos)
1966 security mechanisms. These hash the password more securely
1967 than the mechanisms used in the older LANMAN version of the
1968 SMB protocol but LANMAN based authentication is needed to
1969 establish sessions with some old SMB servers.
1970
1971 Enabling this option allows the cifs module to mount to older
1972 LANMAN based servers such as OS/2 and Windows 95, but such
1973 mounts may be less secure than mounts using NTLM or more recent
1974 security mechanisms if you are on a public network. Unless you
1975 have a need to access old SMB servers (and are on a private
1976 network) you probably want to say N. Even if this support
1977 is enabled in the kernel build, LANMAN authentication will not be
1978 used automatically. At runtime LANMAN mounts are disabled but
1979 can be set to required (or optional) either in
1980 /proc/fs/cifs (see fs/cifs/README for more detail) or via an
1981 option on the mount command. This support is disabled by
1982 default in order to reduce the possibility of a downgrade
1983 attack.
1984
1985 If unsure, say N.

1987config CIFS_UPCALL
1988 bool "Kerberos/SPNEGO advanced session setup"
1989 depends on CIFS && KEYS
1990 help
1991 Enables an upcall mechanism for CIFS which accesses
1992 userspace helper utilities to provide SPNEGO packaged (RFC 4178)
1993 Kerberos tickets which are needed to mount to certain secure servers
1994 (for which more secure Kerberos authentication is required). If
1995 unsure, say N.

1997config CIFS_XATTR
1998 bool "CIFS extended attributes"
1999 depends on CIFS
2000 help
2001 Extended attributes are name:value pairs associated with inodes by
2002 the kernel or by users (see the attr(5) manual page, or visit
2003 <http://acl.bestbits.at/> for details). CIFS maps the name of
2004 extended attributes beginning with the user namespace prefix
2005 to SMB/CIFS EAs. EAs are stored on Windows servers without the
2006 user namespace prefix, but their names are seen by Linux cifs clients
2007 prefaced by the user namespace prefix. The system namespace
2008 (used by some filesystems to store ACLs) is not supported at
2009 this time.
2010
2011 If unsure, say N.

2013config CIFS_POSIX
2014 bool "CIFS POSIX Extensions"
2015 depends on CIFS_XATTR
2016 help
2017 Enabling this option will cause the cifs client to attempt to
2018 negotiate a newer dialect with servers, such as Samba 3.0.5
2019 or later, that optionally can handle more POSIX like (rather
2020 than Windows like) file behavior. It also enables
2021 support for POSIX ACLs (getfacl and setfacl) to servers
2022 (such as Samba 3.10 and later) which can negotiate
2023 CIFS POSIX ACL support. If unsure, say N.
2024
2025config CIFS_DEBUG2
2026 bool "Enable additional CIFS debugging routines"
2027 depends on CIFS
2028 help
2029 Enabling this option adds a few more debugging routines
2030 to the cifs code which slightly increases the size of
2031 the cifs module and can cause additional logging of debug
2032 messages in some error paths, slowing performance. This
2033 option can be turned off unless you are debugging
2034 cifs problems. If unsure, say N.

2039 help
2040 Enables cifs features under testing. These features are
2041 experimental and currently include DFS support and directory
2042 change notification ie fcntl(F_DNOTIFY), as well as the upcall
2043 mechanism which will be used for Kerberos session negotiation
2044 and uid remapping. Some of these features also may depend on
2045 setting a value of 1 to the pseudo-file /proc/fs/cifs/Experimental
2046 (which is disabled by default). See the file fs/cifs/README
2047 for more details. If unsure, say N.
