+ This is the client VFS module for the SMB3 family of NAS protocols,
+ as well as for earlier dialects such as SMB2.1, SMB2 and the
+ Common Internet File System (CIFS) protocol. CIFS was the successor
+ to the original dialect, the Server Message Block (SMB) protocol, the
+ native file sharing mechanism for most early PC operating systems.
+
+ The SMB3 protocol is supported by most modern operating systems and
+ NAS appliances (e.g. Samba, Windows 8, Windows 2012, MacOS).
+ The older CIFS protocol was included in Windows NT4, 2000 and XP (and
+ later) as well by Samba (which provides excellent CIFS and SMB3
+ server support for Linux and many other operating systems). Limited
+ support for OS/2 and Windows ME and similar very old servers is
+ provided as well.
+
+ The cifs module provides an advanced network file system client
+ for mounting to SMB3 (and 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.
+
+ In general, the default dialects, SMB3 and later, enable better
+ performance, security and features, than would be possible with CIFS.
+ Note that when mounting to Samba, due to the CIFS POSIX extensions,
+ CIFS mounts can provide slightly better POSIX compatibility
+ than SMB3 mounts. SMB2/SMB3 mount options are also
+ slightly simpler (compared to CIFS) due to protocol improvements.
+
+ If you need to mount to Samba, Macs 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_ALLOW_INSECURE_LEGACY
+ bool "Support legacy servers which use less secure dialects"
+ depends on CIFS
+ default y
+ help
+ Modern dialects, SMB2.1 and later (including SMB3 and 3.1.1), have
+ additional security features, including protection against
+ man-in-the-middle attacks and stronger crypto hashes, so the use
+ of legacy dialects (SMB1/CIFS and SMB2.0) is discouraged.
+
+ Disabling this option prevents users from using vers=1.0 or vers=2.0
+ on mounts with cifs.ko
+
+ If unsure, say Y.
+
+config CIFS_WEAK_PW_HASH
+ bool "Support legacy servers which use weaker LANMAN security"
+ depends on CIFS && CIFS_ALLOW_INSECURE_LEGACY
+ 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
+ select DNS_RESOLVER
+ 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 Y.
+
+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 Y.
+
+config CIFS_POSIX
+ bool "CIFS POSIX Extensions"
+ depends on CIFS && CIFS_ALLOW_INSECURE_LEGACY && 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_ACL
+ bool "Provide CIFS ACL support"
+ depends on CIFS_XATTR && KEYS
+ help
+ Allows fetching CIFS/NTFS ACL from the server. The DACL blob
+ is handed over to the application/caller. See the man
+ page for getcifsacl for more information. If unsure, say Y.
+
+config CIFS_DEBUG
+ bool "Enable CIFS debugging routines"
+ default y
+ depends on CIFS
+ help
+ Enabling this option adds helpful debugging messages to
+ the cifs code which increases the size of the cifs module.
+ If unsure, say Y.
+config CIFS_DEBUG2
+ bool "Enable additional CIFS debugging routines"
+ depends on CIFS_DEBUG
+ 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_DEBUG_DUMP_KEYS
+ bool "Dump encryption keys for offline decryption (Unsafe)"
+ depends on CIFS_DEBUG
+ help
+ Enabling this will dump the encryption and decryption keys
+ used to communicate on an encrypted share connection on the
+ console. This allows Wireshark to decrypt and dissect
+ encrypted network captures. Enable this carefully.
+ If unsure, say N.
+
+config CIFS_DFS_UPCALL
+ bool "DFS feature support"
+ depends on CIFS && KEYS
+ select DNS_RESOLVER
+ 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 Y.
+
+config CIFS_NFSD_EXPORT
+ bool "Allow nfsd to export CIFS file system"
+ depends on CIFS && BROKEN
+ help
+ Allows NFS server to export a CIFS mounted share (nfsd over cifs)
+
+config CIFS_SMB311
+ bool "SMB3.1.1 network file system support (Experimental)"
+ depends on CIFS
+ select CRYPTO_SHA512
+
+ help
+ This enables experimental support for the newest, SMB3.1.1, dialect.
+ This dialect includes improved security negotiation features.
+ If unsure, say N
+
+config CIFS_FSCACHE
+ bool "Provide CIFS client caching support"
+ depends on CIFS=m && FSCACHE || CIFS=y && FSCACHE=y
+ help
+ Makes CIFS FS-Cache capable. Say Y here if you want your CIFS data
+ to be cached locally on disk through the general filesystem cache
+ manager. If unsure, say N.

+ * List of ioctl/fsctl function codes that are or could be useful in the
+ * future to remote clients like cifs or SMB2/SMB3 client. This is probably
+ * a slightly larger set of fsctls that NTFS local filesystem could handle,
+ * including the seven below that we do not have struct definitions for.
+ * Even with protocol definitions for most of these now available, we still
+ * need to do some experimentation to identify which are practical to do
+ * remotely. Some of the following, such as the encryption/compression ones
+ * could be invoked from tools via a specialized hook into the VFS rather
+ * than via the standard vfs entry points
+ *
+ * See MS-SMB2 Section 2.2.31 (last checked June 2013, all of that list are
+ * below). Additional detail on less common ones can be found in MS-FSCC
+ * section 2.3.
