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. | ||

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. | ||

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. | ||

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 | ||

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. | ||

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. | ||

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 | ||

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 | ||
