+CIFS (Common Internet File System) support
+CONFIG_CIFS
+  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.  CIFS is fully supported by current network
+  file servers such as Windows 2000, Windows 2003 (including  
+  Windows XP) as well by Samba (which provides excellent CIFS
+  server support for Linux and many other operating systems).  
+  The smbfs module should be used instead of this cifs module for
+  mounting to older SMB servers such as OS/2.  The smbfs and cifs
+  modules can coexist and do not conflict.
+
+  The intent of this module is to provide the most advanced network
+  file system function for CIFS compliant servers, including better
+  POSIX compliance, secure per-user session establishment, high
+  performance safe distributed caching (oplock), optional packet
+  signing, Unicode support and other internationalization improvements
+  For more information see the project page at
+  http://us1.samba.org/samba/Linux_CIFS_client.html 
+
+CIFS Debugging
+CONFIG_CIFS_DEBUG
+  If you are experiencing any problems with the CIFS filesystem, say
+  Y here.  This will result in additional debugging messages to be
+  written to the system log.  Under normal circumstances, this
+  results in very little overhead.

 SMB file system support (to mount Windows shares etc.)

   SMB (Server Message Block) is the protocol Windows for Workgroups

+  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.  CIFS is fully supported by current network
+  file servers such as Windows 2000, Windows 2003 (including  
+  Windows XP) as well by Samba (which provides excellent CIFS
+  server support for Linux and many other operating systems), so
+  this network filesystem client can mount to a wide variety of
+  servers.  The smbfs module should be used instead of this cifs module
+  for mounting to older SMB servers such as OS/2.  The smbfs and cifs
+  modules can coexist and do not conflict.  The CIFS VFS filesystem
+  module is designed to work well with servers that implement the
+  newer versions (dialects) of the SMB/CIFS protocol such as Samba, 
+  the program written by Andrew Tridgell that turns any Unix host 
+  into a SMB/CIFS file server.
+
+  The intent of this module is to provide the most advanced network
+  file system function for CIFS compliant servers, including better
+  POSIX compliance, secure per-user session establishment, high
+  performance safe distributed caching (oplock), optional packet
+  signing, large files, Unicode support and other internationalization
+  improvements. Since both Samba server and this filesystem client support
+  the CIFS Unix extensions, the combination can provide a reasonable 
+  alternative to NFSv4 for fileserving in some Linux to Linux environments,
+  not just in Linux to Windows environments.
+
+  This filesystem has an optional mount utility (mount.cifs) that can
+  be obtained from the project page and installed in the path in the same
+  directory with the other mount helpers (such as mount.smbfs). 
+  Mounting using the cifs filesystem without installing the mount helper
+  requires specifying the server's ip address.
+
+  For Linux 2.4:
+    mount //anything/here /mnt_target -o
+            user=username,pass=password,unc=//ip_address_of_server/sharename
+
+  For Linux 2.5: 
+    mount //ip_address_of_server/sharename /mnt_target -o user=username, pass=password
+
+
+  For more information on the module see the project page at
+
+      http://us1.samba.org/samba/Linux_CIFS_client.html

@@ -0,0 +1,572 @@
+Version 1.20
+------------
+Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
+info into /proc/fs/cifs/DebugData.  Fix oops in rare oops in readdir 
+(in build_wildcard_path_from_dentry).  Fix mknod to pass type field
+(block/char/fifo) properly.  Remove spurious mount warning log entry when
+credentials passed as mount argument. Set major/minor device number in
+inode for block and char devices when unix extensions enabled.
+
+Version 1.19
+------------
+Fix /proc/fs/cifs/Stats and DebugData display to handle larger
+amounts of return data. Properly limit requests to MAX_REQ (50
+is the usual maximum active multiplex SMB/CIFS requests per server).
+Do not kill cifsd (and thus hurt the other SMB session) when more than one
+session to the same server (but with different userids) exists and one
+of the two user's smb sessions is being removed while leaving the other.
+Do not loop reconnecting in cifsd demultiplex thread when admin
+kills the thread without going through unmount.
+
+Version 1.18
+------------
+Do not rename hardlinked files (since that should be a noop). Flush
+cached write behind data when reopening a file after session abend,
+except when already in write. Grab per socket sem during reconnect 
+to avoid oops in sendmsg if overlapping with reconnect. Do not
+reset cached inode file size on readdir for files open for write on 
+client.
+
+
+Version 1.17
+------------
+Update number of blocks in file so du command is happier (in Linux a fake
+blocksize of 512 is required for calculating number of blocks in inode).
+Fix prepare write of partial pages to read in data from server if possible.
+Fix race on tcpStatus field between unmount and reconnection code, causing
+cifsd process sometimes to hang around forever. Improve out of memory
+checks in cifs_filldir
+
+Version 1.16
+------------
+Fix incorrect file size in file handle based setattr on big endian hardware.
+Fix oops in build_path_from_dentry when out of memory.  Add checks for invalid
+and closing file structs in writepage/partialpagewrite.  Add statistics
+for each mounted share (new menuconfig option). Fix endianness problem in
+volume information displayed in /proc/fs/cifs/DebugData (only affects
+affects big endian architectures). Prevent renames while constructing
+path names for open, mkdir and rmdir.
+
+Version 1.15
+------------
+Change to mempools for alloc smb request buffers and multiplex structs
+to better handle low memory problems (and potential deadlocks).
+
+Version 1.14
+------------
+Fix incomplete listings of large directories on Samba servers when Unix
+extensions enabled.  Fix oops when smb_buffer can not be allocated. Fix
+rename deadlock when writing out dirty pages at same time.
+
+Version 1.13
+------------
+Fix open of files in which O_CREATE can cause the mode to change in
+some cases. Fix case in which retry of write overlaps file close.
+Fix PPC64 build error.  Reduce excessive stack usage in smb password
+hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
+
+Version 1.12
+------------
+Fixes for large file copy, signal handling, socket retry, buffer
+allocation and low memory situations.
+
+Version 1.11
+------------
+Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
+also now allowing support for specifying client netbiosname.  NT4 support added.
+
+Version 1.10
+------------
+Fix reconnection (and certain failed mounts) to properly wake up the
+blocked users thread so it does not seem hung (in some cases was blocked
+until the cifs receive timeout expired). Fix spurious error logging
+to kernel log when application with open network files killed. 
+
+Version 1.09
+------------
+Fix /proc/fs module unload warning message (that could be logged
+to the kernel log). Fix intermittent failure in connectathon
+test7 (hardlink count not immediately refreshed in case in which
+inode metadata can be incorrectly kept cached when time near zero)
+
+Version 1.08
+------------
+Allow file_mode and dir_mode (specified at mount time) to be enforced
+locally (the server already enforced its own ACLs too) for servers
+that do not report the correct mode (do not support the 
+CIFS Unix Extensions).
+
+Version 1.07
+------------
+Fix some small memory leaks in some unmount error paths. Fix major leak

+------------
+Fix caching problem when files opened by multiple clients in which 
+page cache could contain stale data, and write through did
+not occur often enough while file was still open when read ahead

+instance is closed so that the client does not continue using stale local
+copy rather than later modified server copy of file.  Do not reconnect
+when server drops the tcp session prematurely before negotiate
+protocol response.  Fix oops in roepen_file when dentry freed.  Allow
+the support for CIFS Unix Extensions to be disabled via proc interface.

+access many recent Windows servers)
+
+Version 0.83
+------------
+Fix oops when mounting to long server names caused by inverted parms to kmalloc.
+Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled

+to make 2.4 and 2.5 versions more consistent.
+
+
+Version 0.67
+------------
+Fix signal sending so that captive thread (cifsd) exits on umount 
+(which was causing the warning in kmem_cache_free of the request buffers
+at rmmod time).  This had broken as a sideeffect of the recent global
+kernel change to daemonize.  Fix memory leak in readdir code which
+showed up in "ls -R" (and applications that did search rewinding).

+over 16K to allow negotiation of up to Samba and Windows server default read 
+sizes.  Add support for readpages
+
+Version 0.61
+------------
+Fix oops when username not passed in on mount.  Extensive fixes and improvements
+to error logging (strip redundant newlines, change debug macros to ensure newline
+passed in and to be more consistent).  Fix writepage wrong file handle problem,

+file updates through the page cache to multiply open files.  This could cause
+the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
+shares to the same Windows server when using different usernames
+(doing this to Samba servers worked but Windows was rejecting it) - now it is
+possible to use different userids when connecting to the same server from a

+1) Fixed lockrange to be correct (it was one byte too short)
+
+2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly 
+show range as locked when there is a conflict with an existing lock.
+
+3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
+in most cases.  Eventually will offer optional ability to query server for the correct perms.
+
+3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded 
+but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
+session) 
+
+4) Fixed error logging of valid mount options
+
+5) Removed logging of password field.

+and cleaned them up and made them more consistent with other cifs functions. 
+
+7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways 
+(with or without Unix exentions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
+nor is the symlink support using the Unix extensions
+
+8) Started adding the readlink and follow_link code

+       2) Close - to return the last write time to do cache across close more safely
+       3) PosixQFSInfo - to return statfs info
+       4) FindFirst return unique inode number - what about resume key, two forms short (matches readdir) and full (enough info to cache inodes)
+       5) Mkdir - set mode
+       
+       And under consideration: 
+       6) FindClose2 (return nanosecond timestamp ??)
+       7) Use nanosecond timestamps throughout all time fields if 
+          corresponding attribute flag is set

+The CIFS VFS support for Linux supports many advanced network filesystem 
+features such as heirarchical 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.  
+
+For questions or bug reports please contact:
+    sfrench@samba.org (sfrench@us.ibm.com) 
+
+Build instructions:
+==================
+For Linux 2.4:
+1) Get the kernel source (e.g.from http://www.kernel.org)
+and download the cifs vfs source (see the project page
+at http://us1.samba.org/samba/Linux_CIFS_client.html)
+and change directory into the top of the kernel directory
+then patch the kernel (e.g. "patch -p1 < cifs_24.patch") 
+to add the cifs vfs to your kernel configure options if
+it has not already been added (e.g. current SuSE and UL
+users do not need to apply the cifs_24.patch since the cifs vfs is
+already in the kernel configure menu) and then
+mkdir linux/fs/cifs and then copy the current cifs vfs files from
+the cifs download to your kernel build directory e.g.
+
+       cp <cifs_download_dir>/fs/cifs/* to <kernel_download_dir>/fs/cifs
+       
+2) make menuconfig (or make xconfig)
+3) select cifs from within the network filesystem choices
+4) save and exit
+5) make dep
+6) make modules (or "make" if CIFS VFS not to be built as a module)
+
+For Linux 2.5:
+1) Download the kernel (e.g. from http://www.kernel.org or from bitkeeper
+at bk://linux.bkbits.net/linux-2.5) 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.o).
+
+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 3.0 source tree and on 
+the CIFS VFS web site) copy it to the same directory in which mount.smbfs and 
+similar files reside (usually /sbin).  Although the helper software is not  
+required, mount.cifs is recommended.  Eventually the Samba 3.0 utility program 
+"net" may also be helpful since it may someday provide easier mount syntax for
+users who are used to Windows e.g.  net use <mount point> <UNC name or cifs URL>  
+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
+trivially built from Samba 3.0 or later source e.g. by executing:
+
+       gcc samba/source/client/mount.cifs.c -o mount.cifs
+
+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: 
+ 
+        gcc samba/source/client/mount.cifs.c -DCIFS_ALLOW_USR_SUID -o mount.cifs
+
+There is a corresponding manual page for cifs mounting in the Samba 3.0 and
+later source tree in docs/manpages/mount.cifs.8 
+
+Samba Considerations 
+==================== 
+To get the maximum benefit from the CIFS VFS, we recommend using a server that 
+supports the SNIA CIFS Unix Extensions standard (e.g.  Samba 2.2.5 or later or 
+Samba 3.0) 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 ea support is required for supporting Linux xattrs. 
+Some administrators also change the "map archive" and the "create mask" 
+parameters from their default values.  Creating special devices (mknod) 
+remotely may require specifying a mkdev function to Samba if you are not using 
+Samba 3.0.5 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 3.0.5, most symlinks to
+files with absolute paths (ie beginning with slash) such as:
+        ln -s /mnt/foo bar
+would be forbidden. Samba 3.0.5 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.o), you can use mount syntax like the following to access Samba or Windows 
+servers: 
+
+  mount -t cifs //9.53.216.11/e$ /mnt -o user=myname,pass=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:
+
+  user=<username>
+  pass=<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).
+
+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 the NTLM SMB dialect (which is the most recent, supported 
+by Samba and Windows NT version 4, 2000 and XP and many other SMB/CIFS servers) 
+Servers must support either "pure-TCP" (port 445 TCP/IP CIFS connections) or RFC 
+1001/1002 support for "Netbios-Over-TCP/IP." Neither of these is likely to be a 
+problem as most servers support this.  IPv6 support is planned for the future.  
+
+CIFS VFS Mount Options
+======================
+A partial list of the supported mount options follows:
+  user         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 it is 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
+  uid          If CIFS Unix extensions are not supported by the server
+               this overrides the default uid for inodes. 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.  For servers which do not support
+               the Unix extensions, the default uid (and gid) returned on
+               lookup of existing files is 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.  For the uid (gid) of newly
+               created files and directories, ie files created since 
+               the last mount of the server share, the expected uid 
+               (gid) is cached as as long as the inode remains in 
+               memory on the client.   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
+  gid          If CIFS Unix extensions are not supported by the server
+               this overrides the default gid for inodes.
+  file_mode     If CIFS Unix extensions are not supported by the server
+               this overrides the default mode for file inodes.
+  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
+  wsize                default write size
+  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.
+  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.
+
+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 recent 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.
+Stats                  Lists summary resource usage information as well as per
+                       share statistics, if CONFIG_CIFS_STATS in enabled
+                       in the kernel configuration.
+
+Configuration pseudo-files:
+MultiuserMount         If set to one, more than one CIFS session to 
+                       the same server ip address can be established
+                       if more than one uid accesses the same mount
+                       point and if the uids user/password mapping
+                       information is available. (default is 0)
+PacketSigningEnabled   If set to one, cifs packet signing is enabled
+                       and will be used if the server requires 
+                       it.  If set to two, cifs packet signing is
+                       required even if the server considers packet
+                       signing optional. (default 1)
+cifsFYI                        If set to one, additional debug information is
+                       logged to the system error log. (default 0)
+ExtendedSecurity       If set to one, SPNEGO session establishment
+                       is allowed which enables more advanced 
+                       secure CIFS session establishment (default 0)
+NTLMV2Enabled          If set to one, more secure password hashes
+                       are used when the server supports them and
+                       when kerberos is not negotiated (default 0)
+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)
+OplockEnabled          If set to one, safe distributed caching enabled.
+                       (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 1 > /proc/fs/cifs/cifsFYI
+       
+and for more extensive tracing including the start of smb requests and responses
+
+       echo 1 > /proc/fs/cifs/traceSMB
+
+Three other experimental features are under development and to test 
+require enabling an ifdef (e.g. by  adding "#define CIFS_FCNTL" in cifsglob.h)
+
+       CONFIG_CIFS_QUOTA
+
+       CONFIG_CIFS_XATTR
+
+       CONFIG_CIFS_FCNTL  (fcntl needed for support of directory change 
+                           notification and perhaps later for file leases)
+
+Per share (per client mount) statistics are available in /proc/fs/cifs/DebugData
+if the kernel was configured with cifs statistics enabled.  The statistics
+represent the number of successful (ie non-zero return code from the server) 
+SMB responses to some of the more common commands (open, delete, mkdir 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.
+The statistics for the number of total SMBs and oplock breaks are different in
+that they represent all for that share, not just those for which the server
+returned success.
+       
+Also note that "cat /proc/fs/cifs/DebugData" will display information about 
+the active sessions and the shares that are mounted.  Note: NTLMv2 enablement 
+will not work since they its implementation is not quite complete yet.
+Do not alter these configuration values unless you are doing specific testing.  
+Enabling extended security works to Windows 2000 Workstations and XP but not to 
+Windows 2000 server or Samba since it does not usually send "raw NTLMSSP" 
+(instead it sends NTLMSSP encapsulated in SPNEGO/GSSAPI, which support is not 
+complete in the CIFS VFS yet).

+
+   This code makes no attempt to be fast! In fact, it is a very

+
+   This code is NOT a complete DES implementation. It implements only
+   the minimum necessary for SMB authentication, as used by all SMB

+
+   In particular, it can only do a unchained forward DES pass. This

+
+   There is no entry point into this code that allows normal DES operation.
+
+   I believe this means that this code does not come under ITAR

+
+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) Support for SecurityDescriptors for chmod/chgrp/chown so
+these can be supported for Windows servers
+
+b) Better pam/winbind integration
+
+c) multi-user mounts - multiplexed sessionsetups over single vc
+(ie tcp session) - prettying up needed
+
+d) Kerberos/SPNEGO session setup support - (started)
+
+e) NTLMv2 authentication (mostly implemented)
+
+f) MD5-HMAC signing SMB PDUs when SPNEGO style SessionSetup 
+used (Kerberos or NTLMSSP). Signing alreadyimplemented for NTLM
+and raw NTLMSSP already. This is important when enabling
+extended security and mounting to Windows 2003 Servers
+
+f) Directory entry caching relies on a 1 second timer, rather than 
+using FindNotify or equivalent.  - (started)
+
+g) A few byte range testcases fail due to POSIX vs. Windows/CIFS
+style byte range lock differences
+
+h) quota support
+
+i) support for the Linux 2.5 kernel new feature get_xattr and set_xattr
+which will allow us to expose dos attributes as well as real
+ACLs. This support has been started in the current code, but is
+ifdeffed out.
+
+k) finish writepages support (multi-page write behind for improved
+performance) and syncpage
+
+l) hook lower into the sockets api (as NFS/SunRPC does) to avoid the
+extra copy in/out of the socket buffers in some cases.
+
+m) finish support for IPv6.  This is mostly complete but
+needs a simple inet_pton like function to convert ipv6
+addresses in string representation.
+
+o) Better optimize open (and pathbased setfilesize) to reduce the
+oplock breaks coming from windows srv.  Piggyback identical file
+opens on top of each other by incrementing reference count rather
+than resending (helps reduce server resource utilization and avoid
+spurious oplock breaks).
+
+p) Improve performance of readpages by sending more than one read
+at a time when 8 pages or more are requested.  Evaluate whether
+reads larger than 16K would be helpful.
+
+q) For support of Windows9x/98 we need to retry failed mounts
+to *SMBSERVER (default server name) with the uppercase hostname
+in the RFC1001 session_init request.
+
+r) Add Extended Attributed support (for storing UID/GID info
+to Windows servers)
+
+s) Finish fcntl D_NOTIFY support so kde and gnome file list windows
+will autorefresh
+
+t) Add GUI tool to configure /proc/fs/cifs settings and for display of
+the CIFS statistics
+
+KNOWN BUGS (updated May 27, 2004)
+====================================
+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 but Samba has a bug currently handling
+symlink text beginning with slash
+2) follow_link and readdir code does not follow dfs junctions
+but recognizes them
+3) create of new files to FAT partitions on Windows servers can
+succeed but still return access denied (appears to be Windows 
+server not cifs client problem) and has not been reproduced recently.
+NTFS partitions do not have this problem.
+4) debug connectathon lock test case 10 which fails against
+Samba (may be unmappable due to POSIX to Windows lock model
+differences but worth investigating).  Also debug Samba to 
+see why lock test case 7 takes longer to complete to Samba
+than to Windows.
+
+Misc testing to do
+==================
+1) check out max path names and max path name components against various server
+types. Try nested symlinks. Return max path name in stat -f information
+
+2) Modify file portion of ltp so it can run against a mounted network
+share and run it against cifs vfs.
+
+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 the recently added NT4 support against various
+NT4 service pack levels.
