docs: fs: cifs: convert to ReST and add to admin-guide book

The filenames for cifs documentation is not using the same
convention as almost all Kernel documents is using. So,
rename them to a more appropriate name. Then, manually convert
the documentation files for CIFS to ReST.

By doing a manual conversion, we can preserve the original
author's style, while making it to look more like the other
Kernel documents.

Most of the conversion here is trivial. The most complex one was
the README file (which was renamed to usage.rst).

-This module supports the SMB3 family of advanced network protocols (as well
-as older dialects, originally called "CIFS" or SMB1).
-
-The CIFS VFS module 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.  CIFS and now SMB3 has now become a defacto
-standard for interoperating between Macs and Windows and major NAS appliances.
-
-Please see
-  MS-SMB2 (for detailed SMB2/SMB3/SMB3.1.1 protocol specification)
-  http://protocolfreedom.org/ and
-  http://samba.org/samba/PFIF/
-for more details.
-
-
-For questions or bug reports please contact:
-    smfrench@gmail.com
-
-See the project page at: https://wiki.samba.org/index.php/LinuxCIFS_utils
-
-Build instructions:
-==================
-For Linux:
-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.ko).
-
-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 4.x source tree and on
-the CIFS VFS web site) copy it to the same directory in which mount helpers
-reside (usually /sbin).  Although the helper software is not
-required, mount.cifs is recommended.  Most distros include a "cifs-utils"
-package that includes this utility so it is recommended to install this.
-
-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
-found at cifs-utils.git on git.samba.org
-
-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.
-
-Recommendations
-===============
-To improve security the SMB2.1 dialect or later (usually will get SMB3) is now
-the new default. To use old dialects (e.g. to mount Windows XP) use "vers=1.0"
-on mount (or vers=2.0 for Windows Vista).  Note that the CIFS (vers=1.0) is
-much older and less secure than the default dialect SMB3 which includes
-many advanced security features such as downgrade attack detection
-and encrypted shares and stronger signing and authentication algorithms.
-There are additional mount options that may be helpful for SMB3 to get
-improved POSIX behavior (NB: can use vers=3.0 to force only SMB3, never 2.1):
-     "mfsymlinks" and "cifsacl" and "idsfromsid"
-
-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: CIFS_ALLOW_USR_SUID
-
-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 
-====================
-Most current servers support SMB2.1 and SMB3 which are more secure,
-but there are useful protocol extensions for the older less secure CIFS
-dialect, so to get the maximum benefit if mounting using the older dialect
-(CIFS/SMB1), we recommend using a server that supports the SNIA CIFS
-Unix Extensions standard (e.g. almost any  version of Samba ie version
-2.2.5 or later) 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.ko), you can use mount syntax like the following to access Samba or
-Mac or Windows servers:
-
-  mount -t cifs //9.53.216.11/e$ /mnt -o username=myname,password=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:
-
-  username=<username>
-  password=<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). In addition the mount option
-"mapposix" can be used on CIFS (vers=1.0) to force the mapping of
-illegal Windows/NTFS/SMB characters to a remap range (this mount parm
-is the default for SMB3). This remap ("mapposix") range is also
-compatible with Mac (and "Services for Mac" on some older Windows).
-
-CIFS VFS Mount Options
-======================
-A partial list of the supported mount options follows:
-  username	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 specified 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.
-  fsc		Enable local disk caching using FS-Cache (off by default). This
-  		option could be useful to improve performance on a slow link,
-		heavily loaded server and/or network where reading from the
-		disk is faster than reading from the server (over the network).
-		This could also impact scalability positively as the
-		number of calls to the server are reduced. However, local
-		caching is not suitable for all workloads for e.g. read-once
-		type workloads. So, you need to consider carefully your
-		workload/scenario before using this option. Currently, local
-		disk caching is functional for CIFS files opened as read-only.
-  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)
-  actimeo=n	attribute cache timeout in seconds (default 1 second).
-		After this timeout, the cifs client requests fresh attribute
-		information from the server. This option allows to tune the
-		attribute cache timeout to suit the workload needs. Shorter
-		timeouts mean better the cache coherency, but increased number
-		of calls to the server. Longer timeouts mean reduced number
-		of calls to the server at the expense of less stricter cache
-		coherency checks (i.e. incorrect attribute cache for a short
-		period of time).
-  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 mmapping 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.
-  strictcache   Use for switching on strict cache mode. In this mode the
-		client read from the cache all the time it has Oplock Level II,
-		otherwise - read from the server. All written data are stored
-		in the cache, but if the client doesn't have Exclusive Oplock,
-		it writes the data to the server.
-  rwpidforward  Forward pid of a process who opened a file to any read or write
-		operation on that file. This prevent applications like WINE
-		from failing on read and write if we use mandatory brlock style.
-  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 supports 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).
- mfsymlinks     Enable support for Minshall+French symlinks
-		(see http://wiki.samba.org/index.php/UNIX_Extensions#Minshall.2BFrench_symlinks)
-		This option is ignored when specified together with the
-		'sfu' option. Minshall+French symlinks are used even if
-		the server supports the CIFS Unix Extensions.
- 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, features enabled as well as the cifs.ko
-			version.
-Stats			Lists summary resource usage information as well as per
-			share statistics.
-
-Configuration pseudo-files:
-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)
-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)
-
-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 CONFIG_CIFS_STATS2 to be set in kernel configuration
-(.config). 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
-
-Per share (per client mount) statistics are available in /proc/fs/cifs/Stats.
-Additional information is available if CONFIG_CIFS_STATS2 is enabled in the
-kernel configuration (.config).  The statistics returned include counters which
-represent the number of attempted and failed (ie non-zero return code from the
-server) SMB3 (or cifs) requests grouped by request type (read, write, close 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.
-Statistics can be reset to zero by "echo 0 > /proc/fs/cifs/Stats" which may be
-useful if comparing performance of two different scenarios.
-	
-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
-
-CIFS kernel module parameters
-=============================
-These module parameters can be specified or modified either during the time of
-module loading or during the runtime by using the interface
-	/proc/module/cifs/parameters/<param>
-
-i.e. echo "value" > /sys/module/cifs/parameters/<param>
-
-1. enable_oplocks - Enable or disable oplocks. Oplocks are enabled by default.
-		    [Y/y/1]. To disable use any of [N/n/0].

-Version 2.14 December 21, 2018
-
-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) SMB3 (and SMB3.1.1) missing optional features:
-   - multichannel (started), integration with RDMA
-   - directory leases (improved metadata caching), started (root dir only)
-   - T10 copy offload ie "ODX" (copy chunk, and "Duplicate Extents" ioctl
-     currently the only two server side copy mechanisms supported)
-
-b) improved sparse file support
-
-c) Directory entry caching relies on a 1 second timer, rather than
-using Directory Leases, currently only the root file handle is cached longer
-
-d) quota support (needs minor kernel change since quota calls
-to make it to network filesystems or deviceless filesystems)
-
-e) Additional use cases where we use "compoounding" (e.g. open/query/close
-and open/setinfo/close) to reduce the number of roundtrips, and also
-open to reduce redundant opens (using deferred close and reference counts more).
-
-f) Finish inotify 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.   
-
-g) Add GUI tool to configure /proc/fs/cifs settings and for display of
-the CIFS statistics (started)
-
-h) implement support for security and trusted categories of xattrs
-(requires minor protocol extension) to enable better support for SELINUX
-
-i) Add support for tree connect contexts (see MS-SMB2) a new SMB3.1.1 protocol
-   feature (may be especially useful for virtualization).
-
-j) 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. Also better integration with winbind for resolving SID owners
-
-k) Add tools to take advantage of more smb3 specific ioctls and features
-(passthrough ioctl/fsctl for sending various SMB3 fsctls to the server
-is in progress, and a passthrough query_info call is already implemented
-in cifs.ko to allow smb3 info levels queries to be sent from userspace)
-
-l) encrypted file support
-
-m) improved stats gathering tools (perhaps integration with nfsometer?)
-to extend and make easier to use what is currently in /proc/fs/cifs/Stats
-
-n) allow setting more NTFS/SMB3 file attributes remotely (currently limited to compressed
-file attribute via chflags) and improve user space tools for managing and
-viewing them.
-
-o) mount helper GUI (to simplify the various configuration options on mount)
-
-p) Add support for witness protocol (perhaps ioctl to cifs.ko from user space
-   tool listening on witness protocol RPC) to allow for notification of share
-   move, server failover, and server adapter changes.  And also improve other
-   failover scenarios, e.g. when client knows multiple DFS entries point to
-   different servers, and the server we are connected to has gone down.
-
-q) Allow mount.cifs to be more verbose in reporting errors with dialect
-or unsupported feature errors.
-
-r) updating cifs documentation, and user guide.
-
-s) Addressing bugs found by running a broader set of xfstests in standard
-file system xfstest suite.
-
-t) split cifs and smb3 support into separate modules so legacy (and less
-secure) CIFS dialect can be disabled in environments that don't need it
-and simplify the code.
-
-v) POSIX Extensions for SMB3.1.1 (started, create and mkdir support added
-so far).
-
-w) Add support for additional strong encryption types, and additional spnego
-authentication mechanisms (see MS-SMB2)
-
-KNOWN BUGS
-====================================
-See http://bugzilla.samba.org - search on product "CifsVFS" for
-current bug list.  Also check http://bugzilla.kernel.org (Product = File System, Component = CIFS)
-
-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
-
-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) Improve xfstest's cifs/smb3 enablement and adapt xfstests where needed to test
-cifs/smb3 better
-
-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
-
-5) Continue to extend the smb3 "buildbot" which does automated xfstesting
-against Windows, Samba and Azure currently - to add additional tests and
-to allow the buildbot to execute the tests faster. The URL for the
-buildbot is: http://smb3-test-rhel-75.southcentralus.cloudapp.azure.com
-
-6) Address various coverity warnings (most are not bugs per-se, but
-the more warnings are addressed, the easier it is to spot real
-problems that static analyzers will point out in the future).

-  This is the client VFS module for the SMB3 NAS protocol as well
-  as for older dialects such as the Common Internet File System (CIFS)
-  protocol which was the successor to the Server Message Block
-  (SMB) protocol, the native file sharing mechanism for most early
-  PC operating systems. New and improved versions of CIFS are now
-  called SMB2 and SMB3. Use of SMB3 (and later, including SMB3.1.1)
-  is strongly preferred over using older dialects like CIFS due to
-  security reaasons. All modern dialects, including the most recent,
-  SMB3.1.1 are supported by the CIFS VFS module. The SMB3 protocol
-  is implemented and supported by all major file servers
-  such as all modern versions of Windows (including Windows 2016
-  Server), as well as by Samba (which provides excellent
-  CIFS/SMB2/SMB3 server support and tools for Linux and many other
-  operating systems).  Apple systems also support SMB3 well, as
-  do most Network Attached Storage vendors, so this network
-  filesystem client can mount to a wide variety of systems.
-  It also supports mounting to the cloud (for example
-  Microsoft Azure), including the necessary security features.
-
-  The intent of this module is to provide the most advanced network
-  file system function for SMB3 compliant servers, including advanced
-  security features, excellent parallelized high performance i/o, better
-  POSIX compliance, secure per-user session establishment, encryption,
-  high performance safe distributed caching (leases/oplocks), optional packet
-  signing, large files, Unicode support and other internationalization
-  improvements. Since both Samba server and this filesystem client support
-  the CIFS Unix extensions (and in the future SMB3 POSIX extensions),
-  the combination can provide a reasonable alternative to other network and
-  cluster file systems for fileserving in some Linux to Linux environments,
-  not just in Linux to Windows (or Linux to Mac) environments.
-
-  This filesystem has a mount utility (mount.cifs) and various user space
-  tools (including smbinfo and setcifsacl) that can be obtained from
-
-      https://git.samba.org/?p=cifs-utils.git
-  or
-      git://git.samba.org/cifs-utils.git
-
-  mount.cifs should be installed in the directory with the other mount helpers.
