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.

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. -+ ---- /dev/null -+++ b/fs/cifs/transport.c -@@ -0,0 +1,434 @@ -+/* -+ * fs/cifs/transport.c -+ * -+ * Copyright (C) International Business Machines Corp., 2002,2004 -+ * Author(s): Steve French (sfrench@us.ibm.com) -+ * -+ * This library is free software; you can redistribute it and/or modify -+ * it under the terms of the GNU Lesser General Public License as published -+ * by the Free Software Foundation; either version 2.1 of the License, or -+ * (at your option) any later version. -+ * -+ * This library is distributed in the hope that it will be useful, -+ * but WITHOUT ANY WARRANTY; without even the implied warranty of -+ * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
