9 +CIFS (Common Internet File System) support
10 +CONFIG_CIFS
11 +  This is the client VFS module for the Common Internet File System
12 +  (CIFS) protocol which is the successor to the Server Message Block 
13 +  (SMB) protocol, the native file sharing mechanism for most early
14 +  PC operating systems.  CIFS is fully supported by current network
15 +  file servers such as Windows 2000, Windows 2003 (including  
16 +  Windows XP) as well by Samba (which provides excellent CIFS
17 +  server support for Linux and many other operating systems).  
18 +  The smbfs module should be used instead of this cifs module for
19 +  mounting to older SMB servers such as OS/2.  The smbfs and cifs
20 +  modules can coexist and do not conflict.
21 +
22 +  The intent of this module is to provide the most advanced network
23 +  file system function for CIFS compliant servers, including better
24 +  POSIX compliance, secure per-user session establishment, high
25 +  performance safe distributed caching (oplock), optional packet
26 +  signing, Unicode support and other internationalization improvements
27 +  For more information see the project page at

30 +CIFS Debugging
31 +CONFIG_CIFS_DEBUG
32 +  If you are experiencing any problems with the CIFS filesystem, say
33 +  Y here.  This will result in additional debugging messages to be
34 +  written to the system log.  Under normal circumstances, this
35 +  results in very little overhead.  
36 +
37  SMB file system support (to mount Windows shares etc.)
38  CONFIG_SMB_FS

64 +  server support for Linux and many other operating systems), so
65 +  this network filesystem client can mount to a wide variety of
66 +  servers.  The smbfs module should be used instead of this cifs module
67 +  for mounting to older SMB servers such as OS/2.  The smbfs and cifs
68 +  modules can coexist and do not conflict.  The CIFS VFS filesystem
69 +  module is designed to work well with servers that implement the
70 +  newer versions (dialects) of the SMB/CIFS protocol such as Samba, 
71 +  the program written by Andrew Tridgell that turns any Unix host 
72 +  into a SMB/CIFS file server.
73 +
74 +  The intent of this module is to provide the most advanced network
75 +  file system function for CIFS compliant servers, including better
76 +  POSIX compliance, secure per-user session establishment, high
77 +  performance safe distributed caching (oplock), optional packet
78 +  signing, large files, Unicode support and other internationalization
79 +  improvements. Since both Samba server and this filesystem client support
80 +  the CIFS Unix extensions, the combination can provide a reasonable 
81 +  alternative to NFSv4 for fileserving in some Linux to Linux environments,
82 +  not just in Linux to Windows environments.
83 +
84 +  This filesystem has an optional mount utility (mount.cifs) that can
85 +  be obtained from the project page and installed in the path in the same
86 +  directory with the other mount helpers (such as mount.smbfs). 
87 +  Mounting using the cifs filesystem without installing the mount helper
88 +  requires specifying the server's ip address.
89 +
90 +  For Linux 2.4:
91 +    mount //anything/here /mnt_target -o
92 +            user=username,pass=password,unc=//ip_address_of_server/sharename
93 +
94 +  For Linux 2.5: 
95 +    mount //ip_address_of_server/sharename /mnt_target -o user=username, pass=password
96 +

778 +info into /proc/fs/cifs/DebugData.  Fix oops in rare oops in readdir 
779 +(in build_wildcard_path_from_dentry).  Fix mknod to pass type field
780 +(block/char/fifo) properly.  Remove spurious mount warning log entry when
781 +credentials passed as mount argument. Set major/minor device number in

783 +
784 +Version 1.19
785 +------------
786 +Fix /proc/fs/cifs/Stats and DebugData display to handle larger
787 +amounts of return data. Properly limit requests to MAX_REQ (50
788 +is the usual maximum active multiplex SMB/CIFS requests per server).
789 +Do not kill cifsd (and thus hurt the other SMB session) when more than one
790 +session to the same server (but with different userids) exists and one
791 +of the two user's smb sessions is being removed while leaving the other.

809 +Fix prepare write of partial pages to read in data from server if possible.
810 +Fix race on tcpStatus field between unmount and reconnection code, causing

821 +affects big endian architectures). Prevent renames while constructing
822 +path names for open, mkdir and rmdir.
823 +
824 +Version 1.15

880 +------------
881 +Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
882 +This allows files that differ only in case and improves performance of file
883 +creation and file open to such servers.  Fix semaphore conflict which causes 
884 +slow delete of open file to Samba (which unfortunately can cause an oplock

909 +(read oplock) not allowed.  Treat "sep=" when first mount option
910 +as an overrride of comma as the default separator between mount

926 +instance is closed so that the client does not continue using stale local
927 +copy rather than later modified server copy of file.  Do not reconnect
928 +when server drops the tcp session prematurely before negotiate
929 +protocol response.  Fix oops in roepen_file when dentry freed.  Allow

19963 +The CIFS VFS support for Linux supports many advanced network filesystem 
19964 +features such as heirarchical dfs like namespace, hardlinks, locking and more.  
19965 +It was designed to comply with the SNIA CIFS Technical Reference (which 
19966 +supersedes the 1992 X/Open SMB Standard) as well as to perform best practice

19972 +
19973 +Build instructions:
19974 +==================
19975 +For Linux 2.4:
19976 +1) Get the kernel source (e.g.from http://www.kernel.org)
19977 +and download the cifs vfs source (see the project page
19978 +at http://us1.samba.org/samba/Linux_CIFS_client.html)
19979 +and change directory into the top of the kernel directory
19980 +then patch the kernel (e.g. "patch -p1 < cifs_24.patch") 
19981 +to add the cifs vfs to your kernel configure options if
19982 +it has not already been added (e.g. current SuSE and UL
19983 +users do not need to apply the cifs_24.patch since the cifs vfs is
19984 +already in the kernel configure menu) and then
19985 +mkdir linux/fs/cifs and then copy the current cifs vfs files from
19986 +the cifs download to your kernel build directory e.g.
19987 +
19988 +       cp <cifs_download_dir>/fs/cifs/* to <kernel_download_dir>/fs/cifs
19989 +       
19990 +2) make menuconfig (or make xconfig)
19991 +3) select cifs from within the network filesystem choices
19992 +4) save and exit
19993 +5) make dep
19994 +6) make modules (or "make" if CIFS VFS not to be built as a module)
19995 +
19996 +For Linux 2.5:
19997 +1) Download the kernel (e.g. from http://www.kernel.org or from bitkeeper
19998 +at bk://linux.bkbits.net/linux-2.5) and change directory into the top
19999 +of the kernel directory tree (e.g. /usr/src/linux-2.5.73)
20000 +2) make menuconfig (or make xconfig)
20001 +3) select cifs from within the network filesystem choices
20002 +4) save and exit
20003 +5) make
20004 +
20005 +
20006 +Installation instructions:
20007 +=========================
20008 +If you have built the CIFS vfs as module (successfully) simply
20009 +type "make modules_install" (or if you prefer, manually copy the file to
20010 +the modules directory e.g. /lib/modules/2.4.10-4GB/kernel/fs/cifs/cifs.o).
20011 +
20012 +If you have built the CIFS vfs into the kernel itself, follow the instructions
20013 +for your distribution on how to install a new kernel (usually you
20014 +would simply type "make install").
20015 +
20016 +If you do not have the utility mount.cifs (in the Samba 3.0 source tree and on 
20017 +the CIFS VFS web site) copy it to the same directory in which mount.smbfs and 
20018 +similar files reside (usually /sbin).  Although the helper software is not  
20019 +required, mount.cifs is recommended.  Eventually the Samba 3.0 utility program 
20020 +"net" may also be helpful since it may someday provide easier mount syntax for
20021 +users who are used to Windows e.g.  net use <mount point> <UNC name or cifs URL>  
20022 +Note that running the Winbind pam/nss module (logon service) on all of your
20023 +Linux clients is useful in mapping Uids and Gids consistently across the
20024 +domain to the proper network user.  The mount.cifs mount helper can be
20025 +trivially built from Samba 3.0 or later source e.g. by executing:
20026 +
20027 +       gcc samba/source/client/mount.cifs.c -o mount.cifs
20028 +
20029 +Note that when the mount.cifs utility is run suid (allowing user mounts), 
20030 +in order to reduce risks, the "nosuid" mount flag is passed in on mount to
20031 +disallow execution of an suid program mounted on the remote target.
20032 +When mount is executed as root, nosuid is not passed in by default,
20033 +and execution of suid programs on the remote target would be enabled
20034 +by default. This can be changed, as with nfs and other filesystems, 
20035 +by simply specifying "nosuid" among the mount options. For user mounts 
20036 +though to be able to pass the suid flag to mount requires rebuilding 
20037 +mount.cifs with the following flag: 
20038
20039 +        gcc samba/source/client/mount.cifs.c -DCIFS_ALLOW_USR_SUID -o mount.cifs
20040 +
20041 +There is a corresponding manual page for cifs mounting in the Samba 3.0 and
20042 +later source tree in docs/manpages/mount.cifs.8 
20043 +
20044 +Samba Considerations 
20045 +==================== 
20046 +To get the maximum benefit from the CIFS VFS, we recommend using a server that 
20047 +supports the SNIA CIFS Unix Extensions standard (e.g.  Samba 2.2.5 or later or 
20048 +Samba 3.0) but the CIFS vfs works fine with a wide variety of CIFS servers.  
20049 +Note that uid, gid and file permissions will display default values if you do 
20050 +not have a server that supports the Unix extensions for CIFS (such as Samba 
20051 +2.2.5 or later).  To enable the Unix CIFS Extensions in the Samba server, add 
20052 +the line: 
20053 +
20054 +       unix extensions = yes
20055 +       
20056 +to your smb.conf file on the server.  Note that the following smb.conf settings 
20057 +are also useful (on the Samba server) when the majority of clients are Unix or 
20058 +Linux: 
20059 +
20060 +       case sensitive = yes
20061 +       delete readonly = yes 
20062 +       ea support = yes
20063 +
20064 +Note that ea support is required for supporting Linux xattrs. 
20065 +Some administrators also change the "map archive" and the "create mask" 
20066 +parameters from their default values.  Creating special devices (mknod) 
20067 +remotely may require specifying a mkdev function to Samba if you are not using 
20068 +Samba 3.0.5 or later.  For more information on these see the manual pages
20069 +("man smb.conf") on the Samba server system.  Note that the cifs vfs,
20070 +unlike the smbfs vfs, does not read the smb.conf on the client system 
20071 +(the few optional settings are passed in on mount via -o parameters instead).  
20072 +Note that Samba 2.2.7 or later includes a fix that allows the CIFS VFS to delete
20073 +open files (required for strict POSIX compliance).  Windows Servers already 
20074 +supported this feature. Samba server does not allow symlinks that refer to files
20075 +outside of the share, so in Samba versions prior to 3.0.5, most symlinks to
20076 +files with absolute paths (ie beginning with slash) such as:
20077 +        ln -s /mnt/foo bar
20078 +would be forbidden. Samba 3.0.5 server or later includes the ability to create 
20079 +such symlinks safely by converting unsafe symlinks (ie symlinks to server 
20080 +files that are outside of the share) to a samba specific format on the server
20081 +that is ignored by local server applications and non-cifs clients and that will
20082 +not be traversed by the Samba server).  This is opaque to the Linux client
20083 +application using the cifs vfs. Absolute symlinks will work to Samba 3.0.5 or
20084 +later, but only for remote clients using the CIFS Unix extensions, and will
20085 +be invisbile to Windows clients and typically will not affect local
20086 +applications running on the same server as Samba.  
20087 +
20088 +Use instructions:
20089 +================
20090 +Once the CIFS VFS support is built into the kernel or installed as a module 
20091 +(cifs.o), you can use mount syntax like the following to access Samba or Windows 
20092 +servers: 
20093 +
20094 +  mount -t cifs //9.53.216.11/e$ /mnt -o user=myname,pass=mypassword
20095 +
20096 +Before -o the option -v may be specified to make the mount.cifs
20097 +mount helper display the mount steps more verbosely.  
20098 +After -o the following commonly used cifs vfs specific options
20099 +are supported:
20100 +
20101 +  user=<username>
20102 +  pass=<password>
20103 +  domain=<domain name>
20104 +  
20105 +Other cifs mount options are described below.  Use of TCP names (in addition to
20106 +ip addresses) is available if the mount helper (mount.cifs) is installed. If
20107 +you do not trust the server to which are mounted, or if you do not have
20108 +cifs signing enabled (and the physical network is insecure), consider use
20109 +of the standard mount options "noexec" and "nosuid" to reduce the risk of 
20110 +running an altered binary on your local system (downloaded from a hostile server
20111 +or altered by a hostile router).
20112 +
20113 +When using the mount helper mount.cifs, passwords may be specified via alternate
20114 +mechanisms, instead of specifying it after -o using the normal "pass=" syntax
20115 +on the command line:
20116 +1) By including it in a credential file. Specify credentials=filename as one
20117 +of the mount options. Credential files contain two lines
20118 +        username=someuser
20119 +        password=your_password
20120 +2) By specifying the password in the PASSWD environment variable (similarly
20121 +the user name can be taken from the USER environment variable).
20122 +3) By specifying the password in a file by name via PASSWD_FILE
20123 +4) By specifying the password in a file by file descriptor via PASSWD_FD
20124 +
20125 +If no password is provided, mount.cifs will prompt for password entry
20126 +
20127 +Restrictions
20128 +============
20129 +Servers must support the NTLM SMB dialect (which is the most recent, supported 
20130 +by Samba and Windows NT version 4, 2000 and XP and many other SMB/CIFS servers) 
20131 +Servers must support either "pure-TCP" (port 445 TCP/IP CIFS connections) or RFC 
20132 +1001/1002 support for "Netbios-Over-TCP/IP." Neither of these is likely to be a 
20133 +problem as most servers support this.  IPv6 support is planned for the future.  
20134 +
20135 +CIFS VFS Mount Options
20136 +======================
20137 +A partial list of the supported mount options follows:
20138 +  user         The user name to use when trying to establish
20139 +               the CIFS session.
20140 +  password     The user password.  If the mount helper is
20141 +               installed, the user will be prompted for password
20142 +               if it is not supplied.
20143 +  ip           The ip address of the target server
20144 +  unc          The target server Universal Network Name (export) to 
20145 +               mount.  
20146 +  domain       Set the SMB/CIFS workgroup name prepended to the
20147 +               username during CIFS session establishment
20148 +  uid          If CIFS Unix extensions are not supported by the server
20149 +               this overrides the default uid for inodes. For mounts to
20150 +               servers which do support the CIFS Unix extensions, such
20151 +               as a properly configured Samba server, the server provides
20152 +               the uid, gid and mode.  For servers which do not support
20153 +               the Unix extensions, the default uid (and gid) returned on
20154 +               lookup of existing files is the uid (gid) of the person
20155 +               who executed the mount (root, except when mount.cifs
20156 +               is configured setuid for user mounts) unless the "uid=" 
20157 +               (gid) mount option is specified.  For the uid (gid) of newly
20158 +               created files and directories, ie files created since

20160 +               (gid) is cached as as long as the inode remains in

20162 +               checks (authorization checks) on accesses to a file occur
20163 +               at the server, but there are cases in which an administrator
20164 +               may want to restrict at the client as well.  For those
20165 +               servers which do not report a uid/gid owner
20166 +               (such as Windows), permissions can also be checked at the
20167 +               client, and a crude form of client side permission checking 
20168 +               can be enabled by specifying file_mode and dir_mode on 
20169 +               the client
20170 +  gid          If CIFS Unix extensions are not supported by the server
20171 +               this overrides the default gid for inodes.
20172 +  file_mode     If CIFS Unix extensions are not supported by the server
20173 +               this overrides the default mode for file inodes.
20174 +  dir_mode      If CIFS Unix extensions are not supported by the server 
20175 +               this overrides the default mode for directory inodes.
20176 +  port         attempt to contact the server on this tcp port, before
20177 +               trying the usual ports (port 445, then 139).
20178 +  iocharset     Codepage used to convert local path names to and from
20179 +               Unicode. Unicode is used by default for network path
20180 +               names if the server supports it.  If iocharset is
20181 +               not specified then the nls_default specified
20182 +               during the local client kernel build will be used.
20183 +               If server does not support Unicode, this parameter is
20184 +               unused.

20190 +  version      used to distinguish different versions of the
20191 +               mount helper utility (not typically needed)
20192 +  sep          if first mount option (after the -o), overrides
20193 +               the comma as the separator between the mount
20194 +               parms. e.g.
20195 +                       -o user=myname,password=mypassword,domain=mydom
20196 +               could be passed instead with period as the separator by
20197 +                       -o sep=.user=myname.password=mypassword.domain=mydom
20198 +               this might be useful when comma is contained within username
20199 +               or password or domain. This option is less important
20200 +               when the cifs mount helper cifs.mount (version 1.1 or later)
20201 +               is used.
20202 +  nosuid        Do not allow remote executables with the suid bit 
20203 +               program to be executed.  This is only meaningful for mounts
20204 +               to servers such as Samba which support the CIFS Unix Extensions.
20205 +               If you do not trust the servers in your network (your mount
20206 +               targets) it is recommended that you specify this option for
20207 +               greater security.
20208 +  suid          Allow remote files on this mountpoint with suid enabled to 
20209 +               be executed (default for mounts when executed as root,
20210 +               nosuid is default for user mounts).
20211 +  credentials   Although ignored by the cifs kernel component, it is used by 
20212 +               the mount helper, mount.cifs. When mount.cifs is installed it
20213 +               opens and reads the credential file specified in order  
20214 +               to obtain the userid and password arguments which are passed to
20215 +               the cifs vfs.
20216 +  guest         Although ignored by the kernel component, the mount.cifs
20217 +               mount helper will not prompt the user for a password
20218 +               if guest is specified on the mount options.  If no
20219 +               password is specified a null password will be used.
20220 +
20221 +The mount.cifs mount helper also accepts a few mount options before -o
20222 +including:
20223 +
20224 +       -S      take password from stdin (equivalent to setting the environment
20225 +               variable "PASSWD_FD=0"
20226 +       -V      print mount.cifs version
20227 +       -?      display simple usage information
20228 +
20229 +With recent 2.6 kernel versions of modutils, the version of the cifs kernel
20230 +module can be displayed via modinfo.

20232 +Misc /proc/fs/cifs Flags and Debug Info
20233 +=======================================
20234 +Informational pseudo-files:
20235 +DebugData              Displays information about active CIFS sessions
20236 +                       and shares.
20237 +Stats                  Lists summary resource usage information as well as per
20238 +                       share statistics, if CONFIG_CIFS_STATS in enabled
20239 +                       in the kernel configuration.
20240 +
20241 +Configuration pseudo-files:
20242 +MultiuserMount         If set to one, more than one CIFS session to 
20243 +                       the same server ip address can be established
20244 +                       if more than one uid accesses the same mount
20245 +                       point and if the uids user/password mapping
20246 +                       information is available. (default is 0)
20247 +PacketSigningEnabled   If set to one, cifs packet signing is enabled
20248 +                       and will be used if the server requires 
20249 +                       it.  If set to two, cifs packet signing is
20250 +                       required even if the server considers packet
20251 +                       signing optional. (default 1)
20252 +cifsFYI                        If set to one, additional debug information is
20253 +                       logged to the system error log. (default 0)
20254 +ExtendedSecurity       If set to one, SPNEGO session establishment
20255 +                       is allowed which enables more advanced 
20256 +                       secure CIFS session establishment (default 0)
20257 +NTLMV2Enabled          If set to one, more secure password hashes
20258 +                       are used when the server supports them and
20259 +                       when kerberos is not negotiated (default 0)
20260 +traceSMB               If set to one, debug information is logged to the
20261 +                       system error log with the start of smb requests
20262 +                       and responses (default 0)
20263 +LookupCacheEnable      If set to one, inode information is kept cached
20264 +                       for one second improving performance of lookups
20265 +                       (default 1)
20266 +OplockEnabled          If set to one, safe distributed caching enabled.
20267 +                       (default 1)
20268 +LinuxExtensionsEnabled If set to one then the client will attempt to
20269 +                       use the CIFS "UNIX" extensions which are optional
20270 +                       protocol enhancements that allow CIFS servers
20271 +                       to return accurate UID/GID information as well
20272 +                       as support symbolic links. If you use servers
20273 +                       such as Samba that support the CIFS Unix
20274 +                       extensions but do not want to use symbolic link
20275 +                       support and want to map the uid and gid fields 
20276 +                       to values supplied at mount (rather than the 
20277 +                       actual values, then set this to zero. (default 1)
20278 +
20279 +These experimental features and tracing can be enabled by changing flags in 
20280 +/proc/fs/cifs (after the cifs module has been installed or built into the 
20281 +kernel, e.g.  insmod cifs).  To enable a feature set it to 1 e.g.  to enable 
20282 +tracing to the kernel message log type: 
20283 +
20284 +       echo 1 > /proc/fs/cifs/cifsFYI
20285 +       
20286 +and for more extensive tracing including the start of smb requests and responses
20287 +
20288 +       echo 1 > /proc/fs/cifs/traceSMB
20289 +
20290 +Three other experimental features are under development and to test 
20291 +require enabling an ifdef (e.g. by  adding "#define CIFS_FCNTL" in cifsglob.h)
20292 +
20293 +       CONFIG_CIFS_QUOTA
20294 +
20295 +       CONFIG_CIFS_XATTR
20296 +
20297 +       CONFIG_CIFS_FCNTL  (fcntl needed for support of directory change 
20298 +                           notification and perhaps later for file leases)
20299 +
20300 +Per share (per client mount) statistics are available in /proc/fs/cifs/DebugData
20301 +if the kernel was configured with cifs statistics enabled.  The statistics
20302 +represent the number of successful (ie non-zero return code from the server) 
20303 +SMB responses to some of the more common commands (open, delete, mkdir etc.).
20304 +Also recorded is the total bytes read and bytes written to the server for
20305 +that share.  Note that due to client caching effects this can be less than the
20306 +number of bytes read and written by the application running on the client.
20307 +The statistics for the number of total SMBs and oplock breaks are different in
20308 +that they represent all for that share, not just those for which the server
20309 +returned success.
20310 +       
20311 +Also note that "cat /proc/fs/cifs/DebugData" will display information about 
20312 +the active sessions and the shares that are mounted.  Note: NTLMv2 enablement 
20313 +will not work since they its implementation is not quite complete yet.
20314 +Do not alter these configuration values unless you are doing specific testing.  
20315 +Enabling extended security works to Windows 2000 Workstations and XP but not to 
20316 +Windows 2000 server or Samba since it does not usually send "raw NTLMSSP" 
20317 +(instead it sends NTLMSSP encapsulated in SPNEGO/GSSAPI, which support is not 
20318 +complete in the CIFS VFS yet).

20434 +
20435 +   This code makes no attempt to be fast! In fact, it is a very
20436 +   slow implementation 
20437 +
20438 +   This code is NOT a complete DES implementation. It implements only
20439 +   the minimum necessary for SMB authentication, as used by all SMB
20440 +   products (including every copy of Microsoft Windows95 ever sold)
20441 +
20442 +   In particular, it can only do a unchained forward DES pass. This
20443 +   means it is not possible to use this code for encryption/decryption
20444 +   of data, instead it is only useful as a "hash" algorithm.
20445 +
20446 +   There is no entry point into this code that allows normal DES operation.
20447 +
20448 +   I believe this means that this code does not come under ITAR
20449 +   regulations but this is NOT a legal opinion. If you are concerned
20450 +   about the applicability of ITAR regulations to this code then you

21486 +A Partial List of Missing Features
21487 +==================================
21488 +
21489 +Contributions are welcome.  There are plenty of opportunities
21490 +for visible, important contributions to this module.  Here
21491 +is a partial list of the known problems and missing features:
21492 +
21493 +a) Support for SecurityDescriptors for chmod/chgrp/chown so
21494 +these can be supported for Windows servers
21495 +
21496 +b) Better pam/winbind integration
21497 +
21498 +c) multi-user mounts - multiplexed sessionsetups over single vc
21499 +(ie tcp session) - prettying up needed
21500 +
21501 +d) Kerberos/SPNEGO session setup support - (started)
21502 +
21503 +e) NTLMv2 authentication (mostly implemented)
21504 +
21505 +f) MD5-HMAC signing SMB PDUs when SPNEGO style SessionSetup 
21506 +used (Kerberos or NTLMSSP). Signing alreadyimplemented for NTLM
21507 +and raw NTLMSSP already. This is important when enabling
21508 +extended security and mounting to Windows 2003 Servers
21509 +
21510 +f) Directory entry caching relies on a 1 second timer, rather than 
21511 +using FindNotify or equivalent.  - (started)
21512 +
21513 +g) A few byte range testcases fail due to POSIX vs. Windows/CIFS
21514 +style byte range lock differences
21515 +
21516 +h) quota support
21517 +
21518 +i) support for the Linux 2.5 kernel new feature get_xattr and set_xattr
21519 +which will allow us to expose dos attributes as well as real
21520 +ACLs. This support has been started in the current code, but is
21521 +ifdeffed out.
21522 +
21523 +k) finish writepages support (multi-page write behind for improved
21524 +performance) and syncpage
21525 +
21526 +l) hook lower into the sockets api (as NFS/SunRPC does) to avoid the
21527 +extra copy in/out of the socket buffers in some cases.
21528 +
21529 +m) finish support for IPv6.  This is mostly complete but
21530 +needs a simple inet_pton like function to convert ipv6
21531 +addresses in string representation.
21532 +
21533 +o) Better optimize open (and pathbased setfilesize) to reduce the
21534 +oplock breaks coming from windows srv.  Piggyback identical file
21535 +opens on top of each other by incrementing reference count rather
21536 +than resending (helps reduce server resource utilization and avoid
21537 +spurious oplock breaks).
21538 +
21539 +p) Improve performance of readpages by sending more than one read
21540 +at a time when 8 pages or more are requested.  Evaluate whether
21541 +reads larger than 16K would be helpful.
21542 +
21543 +q) For support of Windows9x/98 we need to retry failed mounts
21544 +to *SMBSERVER (default server name) with the uppercase hostname
21545 +in the RFC1001 session_init request.
21546 +
21547 +r) Add Extended Attributed support (for storing UID/GID info
21548 +to Windows servers)
21549 +
21550 +s) Finish fcntl D_NOTIFY support so kde and gnome file list windows
21551 +will autorefresh
21552 +
21553 +t) Add GUI tool to configure /proc/fs/cifs settings and for display of
21554 +the CIFS statistics
21555 +
21556 +KNOWN BUGS (updated May 27, 2004)
21557 +====================================
21558 +1) existing symbolic links (Windows reparse points) are recognized but
21559 +can not be created remotely. They are implemented for Samba and those that
21560 +support the CIFS Unix extensions but Samba has a bug currently handling
21561 +symlink text beginning with slash
21562 +2) follow_link and readdir code does not follow dfs junctions
21563 +but recognizes them
21564 +3) create of new files to FAT partitions on Windows servers can
21565 +succeed but still return access denied (appears to be Windows 
21566 +server not cifs client problem) and has not been reproduced recently.
21567 +NTFS partitions do not have this problem.
21568 +4) debug connectathon lock test case 10 which fails against
21569 +Samba (may be unmappable due to POSIX to Windows lock model
21570 +differences but worth investigating).  Also debug Samba to 
21571 +see why lock test case 7 takes longer to complete to Samba
21572 +than to Windows.
21573 +
21574 +Misc testing to do
21575 +==================
21576 +1) check out max path names and max path name components against various server
21577 +types. Try nested symlinks. Return max path name in stat -f information
21578 +
21579 +2) Modify file portion of ltp so it can run against a mounted network
21580 +share and run it against cifs vfs.
21581 +
21582 +3) Additional performance testing and optimization using iozone and similar - 
21583 +there are some easy changes that can be done to parallelize sequential writes,
21584 +and when signing is disabled to request larger read sizes (larger than 
21585 +negotiated size) and send larger write sizes to modern servers.
21586 +
21587 +4) More exhaustively test the recently added NT4 support against various
21588 +NT4 service pack levels.
