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.

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.
