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

31 +  If you are experiencing any problems with the CIFS filesystem, say
32 +  Y here.  This will result in additional debugging messages to be
33 +  written to the system log.  Under normal circumstances, this
34 +  results in very little overhead.

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

777 +
778 +Version 1.19
779 +------------
780 +Fix /proc/fs/cifs/Stats and DebugData display to handle larger
781 +amounts of return data. Properly limit requests to MAX_REQ (50
782 +is the usual maximum active multiplex SMB/CIFS requests per server).
783 +Do not kill cifsd (and thus hurt the other SMB session) when more than one
784 +session to the same server (but with different userids) exists and one

816 +path names for open, mkdir and rmdir.
817 +
818 +Version 1.15

873 +Version 1.06
874 +------------
875 +Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
876 +This allows files that differ only in case and improves performance of file
877 +creation and file open to such servers.  Fix semaphore conflict which causes 
878 +slow delete of open file to Samba (which unfortunately can cause an oplock

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

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

19928 +The CIFS VFS support for Linux supports many advanced network filesystem 
19929 +features such as heirarchical dfs like namespace, hardlinks, locking and more.  
19930 +It was designed to comply with the SNIA CIFS Technical Reference (which 
19931 +supersedes the 1992 X/Open SMB Standard) as well as to perform best practice

19937 +
19938 +Build instructions:
19939 +==================
19940 +For Linux 2.4:
19941 +1) Get the kernel source (e.g.from http://www.kernel.org)
19942 +and download the cifs vfs source (see the project page
19943 +at http://us1.samba.org/samba/Linux_CIFS_client.html)
19944 +and change directory into the top of the kernel directory
19945 +then patch the kernel (e.g. "patch -p1 < cifs_24.patch") 
19946 +to add the cifs vfs to your kernel configure options if
19947 +it has not already been added (e.g. current SuSE and UL
19948 +users do not need to apply the cifs_24.patch since the cifs vfs is
19949 +already in the kernel configure menu) and then
19950 +mkdir linux/fs/cifs and then copy the current cifs vfs files from
19951 +the cifs download to your kernel build directory e.g.
19952 +
19953 +       cp <cifs_download_dir>/fs/cifs/* to <kernel_download_dir>/fs/cifs
19954 +       
19955 +2) make menuconfig (or make xconfig)
19956 +3) select cifs from within the network filesystem choices
19957 +4) save and exit
19958 +5) make dep
19959 +6) make modules (or "make" if CIFS VFS not to be built as a module)
19960 +
19961 +For Linux 2.5:
19962 +1) Download the kernel (e.g. from http://www.kernel.org or from bitkeeper
19963 +at bk://linux.bkbits.net/linux-2.5) and change directory into the top
19964 +of the kernel directory tree (e.g. /usr/src/linux-2.5.73)
19965 +2) make menuconfig (or make xconfig)
19966 +3) select cifs from within the network filesystem choices
19967 +4) save and exit
19968 +5) make
19969 +
19970 +
19971 +Installation instructions:
19972 +=========================
19973 +If you have built the CIFS vfs as module (successfully) simply
19974 +type "make modules_install" (or if you prefer, manually copy the file to
19975 +the modules directory e.g. /lib/modules/2.4.10-4GB/kernel/fs/cifs/cifs.o).
19976 +
19977 +If you have built the CIFS vfs into the kernel itself, follow the instructions
19978 +for your distribution on how to install a new kernel (usually you
19979 +would simply type "make install").
19980 +
19981 +If you do not have the utility mount.cifs (in the Samba 3.0 source tree and on 
19982 +the CIFS VFS web site) copy it to the same directory in which mount.smbfs and 
19983 +similar files reside (usually /sbin).  Although the helper software is not  
19984 +required, mount.cifs is recommended.  Eventually the Samba 3.0 utility program 
19985 +"net" may also be helpful since it may someday provide easier mount syntax for
19986 +users who are used to Windows e.g.  net use <mount point> <UNC name or cifs URL>  
19987 +Note that running the Winbind pam/nss module (logon service) on all of your
19988 +Linux clients is useful in mapping Uids and Gids consistently across the
19989 +domain to the proper network user.  The mount.cifs mount helper can be
19990 +trivially built from Samba 3.0 or later source e.g. by executing:
19991 +
19992 +       gcc samba/source/client/mount.cifs.c -o mount.cifs
19993 +
19994 +Note that when the mount.cifs utility is run suid (allowing user mounts), 
19995 +in order to reduce risks, the "nosuid" mount flag is passed in on mount to
19996 +disallow execution of an suid program mounted on the remote target.
19997 +When mount is executed as root, nosuid is not passed in by default,
19998 +and execution of suid programs on the remote target would be enabled
19999 +by default. This can be changed, as with nfs and other filesystems, 
20000 +by simply specifying "nosuid" among the mount options. For user mounts 
20001 +though to be able to pass the suid flag to mount requires rebuilding 
20002 +mount.cifs with the following flag: 
20003
20004 +        gcc samba/source/client/mount.cifs.c -DCIFS_ALLOW_USR_SUID -o mount.cifs
20005 +
20006 +There is a corresponding manual page for cifs mounting in the Samba 3.0 and
20007 +later source tree in docs/manpages/mount.cifs.8 
20008 +
20009 +Samba Considerations 
20010 +==================== 
20011 +To get the maximum benefit from the CIFS VFS, we recommend using a server that 
20012 +supports the SNIA CIFS Unix Extensions standard (e.g.  Samba 2.2.5 or later or 
20013 +Samba 3.0) but the CIFS vfs works fine with a wide variety of CIFS servers.  
20014 +Note that uid, gid and file permissions will display default values if you do 
20015 +not have a server that supports the Unix extensions for CIFS (such as Samba 
20016 +2.2.5 or later).  To enable the Unix CIFS Extensions in the Samba server, add 
20017 +the line: 
20018 +
20019 +       unix extensions = yes
20020 +       
20021 +to your smb.conf file on the server.  Note that the following smb.conf settings 
20022 +are also useful (on the Samba server) when the majority of clients are Unix or 
20023 +Linux: 
20024 +
20025 +       case sensitive = yes
20026 +       delete readonly = yes 
20027 +       ea support = yes
20028 +
20029 +Note that ea support is required for supporting Linux xattrs. 
20030 +Some administrators also change the "map archive" and the "create mask" 
20031 +parameters from their default values.  Creating special devices (mknod) 
20032 +remotely may require specifying a mkdev function to Samba if you are not using 
20033 +Samba 3.0.5 or later.  For more information on these see the manual pages
20034 +("man smb.conf") on the Samba server system.  Note that the cifs vfs,
20035 +unlike the smbfs vfs, does not read the smb.conf on the client system 
20036 +(the few optional settings are passed in on mount via -o parameters instead).  
20037 +Note that Samba 2.2.7 or later includes a fix that allows the CIFS VFS to delete
20038 +open files (required for strict POSIX compliance).  Windows Servers already 
20039 +supported this feature. Samba server does not allow symlinks that refer to files
20040 +outside of the share, so in Samba versions prior to 3.0.5, most symlinks to
20041 +files with absolute paths (ie beginning with slash) such as:
20042 +        ln -s /mnt/foo bar
20043 +would be forbidden. Samba 3.0.5 server or later includes the ability to create 
20044 +such symlinks safely by converting unsafe symlinks (ie symlinks to server 
20045 +files that are outside of the share) to a samba specific format on the server
20046 +that is ignored by local server applications and non-cifs clients and that will
20047 +not be traversed by the Samba server).  This is opaque to the Linux client
20048 +application using the cifs vfs. Absolute symlinks will work to Samba 3.0.5 or
20049 +later, but only for remote clients using the CIFS Unix extensions, and will
20050 +be invisbile to Windows clients and typically will not affect local
20051 +applications running on the same server as Samba.  
20052 +
20053 +Use instructions:
20054 +================
20055 +Once the CIFS VFS support is built into the kernel or installed as a module 
20056 +(cifs.o), you can use mount syntax like the following to access Samba or Windows 
20057 +servers: 
20058 +
20059 +  mount -t cifs //9.53.216.11/e$ /mnt -o user=myname,pass=mypassword
20060 +
20061 +Before -o the option -v may be specified to make the mount.cifs
20062 +mount helper display the mount steps more verbosely.  
20063 +After -o the following commonly used cifs vfs specific options
20064 +are supported:
20065 +
20066 +  user=<username>
20067 +  pass=<password>
20068 +  domain=<domain name>
20069 +  
20070 +Other cifs mount options are described below.  Use of TCP names (in addition to
20071 +ip addresses) is available if the mount helper (mount.cifs) is installed. If
20072 +you do not trust the server to which are mounted, or if you do not have
20073 +cifs signing enabled (and the physical network is insecure), consider use
20074 +of the standard mount options "noexec" and "nosuid" to reduce the risk of 
20075 +running an altered binary on your local system (downloaded from a hostile server
20076 +or altered by a hostile router).
20077 +
20078 +When using the mount helper mount.cifs, passwords may be specified via alternate
20079 +mechanisms, instead of specifying it after -o using the normal "pass=" syntax
20080 +on the command line:
20081 +1) By including it in a credential file. Specify credentials=filename as one
20082 +of the mount options. Credential files contain two lines
20083 +        username=someuser
20084 +        password=your_password
20085 +2) By specifying the password in the PASSWD environment variable (similarly
20086 +the user name can be taken from the USER environment variable).
20087 +3) By specifying the password in a file by name via PASSWD_FILE
20088 +4) By specifying the password in a file by file descriptor via PASSWD_FD
20089 +
20090 +If no password is provided, mount.cifs will prompt for password entry
20091 +
20092 +Restrictions
20093 +============
20094 +Servers must support the NTLM SMB dialect (which is the most recent, supported 
20095 +by Samba and Windows NT version 4, 2000 and XP and many other SMB/CIFS servers) 
20096 +Servers must support either "pure-TCP" (port 445 TCP/IP CIFS connections) or RFC 
20097 +1001/1002 support for "Netbios-Over-TCP/IP." Neither of these is likely to be a 
20098 +problem as most servers support this.  IPv6 support is planned for the future.  
20099 +
20100 +CIFS VFS Mount Options
20101 +======================
20102 +A partial list of the supported mount options follows:
20103 +  user         The user name to use when trying to establish
20104 +               the CIFS session.
20105 +  password     The user password.  If the mount helper is
20106 +               installed, the user will be prompted for password
20107 +               if it is not supplied.
20108 +  ip           The ip address of the target server
20109 +  unc          The target server Universal Network Name (export) to 
20110 +               mount.

20113 +  uid          If CIFS Unix extensions are not supported by the server
20114 +               this overrides the default uid for inodes. For mounts to
20115 +               servers which do support the CIFS Unix extensions, such
20116 +               as a properly configured Samba server, the server provides
20117 +               the uid, gid and mode.  For servers which do not support
20118 +               the Unix extensions, the default uid (and gid) returned on
20119 +               lookup of existing files is the uid (gid) of the person
20120 +               who executed the mount (root, except when mount.cifs
20121 +               is configured setuid for user mounts) unless the "uid=" 
20122 +               (gid) mount option is specified.  For the uid (gid) of newly
20123 +               created files and directories, ie files created since 
20124 +               the last mount of the server share, the expected uid 
20125 +               (gid) is cached as as long as the inode remains in 
20126 +               memory on the client.   Also note that permission
20127 +               checks (authorization checks) on accesses to a file occur
20128 +               at the server, but there are cases in which an administrator
20129 +               may want to restrict at the client as well.  For those
20130 +               servers which do not report a uid/gid owner
20131 +               (such as Windows), permissions can also be checked at the
20132 +               client, and a crude form of client side permission checking 
20133 +               can be enabled by specifying file_mode and dir_mode on 
20134 +               the client
20135 +  gid          If CIFS Unix extensions are not supported by the server
20136 +               this overrides the default gid for inodes.
20137 +  file_mode     If CIFS Unix extensions are not supported by the server
20138 +               this overrides the default mode for file inodes.
20139 +  dir_mode      If CIFS Unix extensions are not supported by the server 
20140 +               this overrides the default mode for directory inodes.
20141 +  port         attempt to contact the server on this tcp port, before
20142 +               trying the usual ports (port 445, then 139).
20143 +  iocharset     Codepage used to convert local path names to and from
20144 +               Unicode. Unicode is used by default for network path
20145 +               names if the server supports it.  If iocharset is
20146 +               not specified then the nls_default specified
20147 +               during the local client kernel build will be used.
20148 +               If server does not support Unicode, this parameter is
20149 +               unused.
20150 +  rsize                default read size

20155 +  version      used to distinguish different versions of the
20156 +               mount helper utility (not typically needed)
20157 +  sep          if first mount option (after the -o), overrides
20158 +               the comma as the separator between the mount
20159 +               parms. e.g.
20160 +                       -o user=myname,password=mypassword,domain=mydom
20161 +               could be passed instead with period as the separator by
20162 +                       -o sep=.user=myname.password=mypassword.domain=mydom
20163 +               this might be useful when comma is contained within username
20164 +               or password or domain. This option is less important
20165 +               when the cifs mount helper cifs.mount (version 1.1 or later)
20166 +               is used.
20167 +  nosuid        Do not allow remote executables with the suid bit 
20168 +               program to be executed.  This is only meaningful for mounts
20169 +               to servers such as Samba which support the CIFS Unix Extensions.
20170 +               If you do not trust the servers in your network (your mount
20171 +               targets) it is recommended that you specify this option for
20172 +               greater security.
20173 +  suid          Allow remote files on this mountpoint with suid enabled to 
20174 +               be executed (default for mounts when executed as root,
20175 +               nosuid is default for user mounts).
20176 +  credentials   Although ignored by the cifs kernel component, it is used by 
20177 +               the mount helper, mount.cifs. When mount.cifs is installed it
20178 +               opens and reads the credential file specified in order  
20179 +               to obtain the userid and password arguments which are passed to
20180 +               the cifs vfs.
20181 +  guest         Although ignored by the kernel component, the mount.cifs
20182 +               mount helper will not prompt the user for a password
20183 +               if guest is specified on the mount options.  If no
20184 +               password is specified a null password will be used.
20185 +
20186 +The mount.cifs mount helper also accepts a few mount options before -o
20187 +including:
20188 +
20189 +       -S      take password from stdin (equivalent to setting the environment
20190 +               variable "PASSWD_FD=0"
20191 +       -V      print mount.cifs version
20192 +       -?      display simple usage information
20193 +
20194 +With recent 2.6 kernel versions of modutils, the version of the cifs kernel
20195 +module can be displayed via modinfo.
20196 +
20197 +Misc /proc/fs/cifs Flags and Debug Info
20198 +=======================================
20199 +Informational pseudo-files:
20200 +DebugData              Displays information about active CIFS sessions
20201 +                       and shares.
20202 +Stats                  Lists summary resource usage information as well as per
20203 +                       share statistics, if CONFIG_CIFS_STATS in enabled
20204 +                       in the kernel configuration.
20205 +
20206 +Configuration pseudo-files:
20207 +MultiuserMount         If set to one, more than one CIFS session to 
20208 +                       the same server ip address can be established
20209 +                       if more than one uid accesses the same mount
20210 +                       point and if the uids user/password mapping
20211 +                       information is available. (default is 0)
20212 +PacketSigningEnabled   If set to one, cifs packet signing is enabled
20213 +                       and will be used if the server requires 
20214 +                       it.  If set to two, cifs packet signing is
20215 +                       required even if the server considers packet
20216 +                       signing optional. (default 1)
20217 +cifsFYI                        If set to one, additional debug information is
20218 +                       logged to the system error log. (default 0)
20219 +ExtendedSecurity       If set to one, SPNEGO session establishment
20220 +                       is allowed which enables more advanced 
20221 +                       secure CIFS session establishment (default 0)
20222 +NTLMV2Enabled          If set to one, more secure password hashes
20223 +                       are used when the server supports them and
20224 +                       when kerberos is not negotiated (default 0)
20225 +traceSMB               If set to one, debug information is logged to the
20226 +                       system error log with the start of smb requests
20227 +                       and responses (default 0)
20228 +LookupCacheEnable      If set to one, inode information is kept cached
20229 +                       for one second improving performance of lookups
20230 +                       (default 1)
20231 +OplockEnabled          If set to one, safe distributed caching enabled.
20232 +                       (default 1)
20233 +LinuxExtensionsEnabled If set to one then the client will attempt to
20234 +                       use the CIFS "UNIX" extensions which are optional
20235 +                       protocol enhancements that allow CIFS servers
20236 +                       to return accurate UID/GID information as well
20237 +                       as support symbolic links. If you use servers
20238 +                       such as Samba that support the CIFS Unix
20239 +                       extensions but do not want to use symbolic link
20240 +                       support and want to map the uid and gid fields 
20241 +                       to values supplied at mount (rather than the 
20242 +                       actual values, then set this to zero. (default 1)
20243 +
20244 +These experimental features and tracing can be enabled by changing flags in 
20245 +/proc/fs/cifs (after the cifs module has been installed or built into the 
20246 +kernel, e.g.  insmod cifs).  To enable a feature set it to 1 e.g.  to enable 
20247 +tracing to the kernel message log type: 
20248 +
20249 +       echo 1 > /proc/fs/cifs/cifsFYI
20250 +       
20251 +and for more extensive tracing including the start of smb requests and responses
20252 +
20253 +       echo 1 > /proc/fs/cifs/traceSMB
20254 +
20255 +Three other experimental features are under development and to test 
20256 +require enabling an ifdef (e.g. by  adding "#define CIFS_FCNTL" in cifsglob.h)
20257 +
20258 +       CONFIG_CIFS_QUOTA
20259 +
20260 +       CONFIG_CIFS_XATTR
20261 +
20262 +       CONFIG_CIFS_FCNTL  (fcntl needed for support of directory change 
20263 +                           notification and perhaps later for file leases)
20264 +
20265 +Per share (per client mount) statistics are available in /proc/fs/cifs/DebugData
20266 +if the kernel was configured with cifs statistics enabled.  The statistics
20267 +represent the number of successful (ie non-zero return code from the server) 
20268 +SMB responses to some of the more common commands (open, delete, mkdir etc.).
20269 +Also recorded is the total bytes read and bytes written to the server for
20270 +that share.  Note that due to client caching effects this can be less than the
20271 +number of bytes read and written by the application running on the client.
20272 +The statistics for the number of total SMBs and oplock breaks are different in
20273 +that they represent all for that share, not just those for which the server
20274 +returned success.
20275 +       
20276 +Also note that "cat /proc/fs/cifs/DebugData" will display information about 
20277 +the active sessions and the shares that are mounted.  Note: NTLMv2 enablement 
20278 +will not work since they its implementation is not quite complete yet.
20279 +Do not alter these configuration values unless you are doing specific testing.  
20280 +Enabling extended security works to Windows 2000 Workstations and XP but not to 
20281 +Windows 2000 server or Samba since it does not usually send "raw NTLMSSP" 
20282 +(instead it sends NTLMSSP encapsulated in SPNEGO/GSSAPI, which support is not 
20283 +complete in the CIFS VFS yet).

20398 +   This code makes no attempt to be fast! In fact, it is a very
20399 +   slow implementation 
20400 +
20401 +   This code is NOT a complete DES implementation. It implements only
20402 +   the minimum necessary for SMB authentication, as used by all SMB
20403 +   products (including every copy of Microsoft Windows95 ever sold)
20404 +
20405 +   In particular, it can only do a unchained forward DES pass. This
20406 +   means it is not possible to use this code for encryption/decryption
20407 +   of data, instead it is only useful as a "hash" algorithm.
20408 +
20409 +   There is no entry point into this code that allows normal DES operation.
20410 +
20411 +   I believe this means that this code does not come under ITAR
20412 +   regulations but this is NOT a legal opinion. If you are concerned
20413 +   about the applicability of ITAR regulations to this code then you
20414 +   should confirm it for yourself (and maybe let me know if you come
20415 +   up with a different answer to the one above)

21445 +A Partial List of Missing Features
21446 +==================================
21447 +
21448 +Contributions are welcome.  There are plenty of opportunities
21449 +for visible, important contributions to this module.  Here
21450 +is a partial list of the known problems and missing features:
21451 +
21452 +a) Support for SecurityDescriptors for chmod/chgrp/chown so
21453 +these can be supported for Windows servers
21454 +
21455 +b) Better pam/winbind integration
21456 +
21457 +c) multi-user mounts - multiplexed sessionsetups over single vc
21458 +(ie tcp session) - prettying up needed
21459 +
21460 +d) Kerberos/SPNEGO session setup support - (started)
21461 +
21462 +e) NTLMv2 authentication (mostly implemented)
21463 +
21464 +f) MD5-HMAC signing SMB PDUs when SPNEGO style SessionSetup 
21465 +used (Kerberos or NTLMSSP). Signing alreadyimplemented for NTLM
21466 +and raw NTLMSSP already. This is important when enabling
21467 +extended security and mounting to Windows 2003 Servers
21468 +
21469 +f) Directory entry caching relies on a 1 second timer, rather than 
21470 +using FindNotify or equivalent.  - (started)
21471 +
21472 +g) A few byte range testcases fail due to POSIX vs. Windows/CIFS
21473 +style byte range lock differences
21474 +
21475 +h) quota support
21476 +
21477 +i) support for the Linux 2.5 kernel new feature get_xattr and set_xattr
21478 +which will allow us to expose dos attributes as well as real
21479 +ACLs. This support has been started in the current code, but is
21480 +ifdeffed out.
21481 +
21482 +k) finish writepages support (multi-page write behind for improved
21483 +performance) and syncpage
21484 +
21485 +l) hook lower into the sockets api (as NFS/SunRPC does) to avoid the
21486 +extra copy in/out of the socket buffers in some cases.
21487 +
21488 +m) finish support for IPv6.  This is mostly complete but
21489 +needs a simple inet_pton like function to convert ipv6
21490 +addresses in string representation.
21491 +
21492 +o) Better optimize open (and pathbased setfilesize) to reduce the
21493 +oplock breaks coming from windows srv.  Piggyback identical file
21494 +opens on top of each other by incrementing reference count rather
21495 +than resending (helps reduce server resource utilization and avoid
21496 +spurious oplock breaks).
21497 +
21498 +p) Improve performance of readpages by sending more than one read
21499 +at a time when 8 pages or more are requested.  Evaluate whether
21500 +reads larger than 16K would be helpful.
21501 +
21502 +q) For support of Windows9x/98 we need to retry failed mounts
21503 +to *SMBSERVER (default server name) with the uppercase hostname
21504 +in the RFC1001 session_init request.
21505 +
21506 +r) Add Extended Attributed support (for storing UID/GID info
21507 +to Windows servers)
21508 +
21509 +s) Finish fcntl D_NOTIFY support so kde and gnome file list windows
21510 +will autorefresh
21511 +
21512 +t) Add GUI tool to configure /proc/fs/cifs settings and for display of
21513 +the CIFS statistics
21514 +
21515 +KNOWN BUGS (updated May 27, 2004)
21516 +====================================
21517 +1) existing symbolic links (Windows reparse points) are recognized but
21518 +can not be created remotely. They are implemented for Samba and those that
21519 +support the CIFS Unix extensions but Samba has a bug currently handling
21520 +symlink text beginning with slash
21521 +2) follow_link and readdir code does not follow dfs junctions
21522 +but recognizes them
21523 +3) create of new files to FAT partitions on Windows servers can
21524 +succeed but still return access denied (appears to be Windows 
21525 +server not cifs client problem) and has not been reproduced recently.
21526 +NTFS partitions do not have this problem.
21527 +4) debug connectathon lock test case 10 which fails against
21528 +Samba (may be unmappable due to POSIX to Windows lock model
21529 +differences but worth investigating).  Also debug Samba to 
21530 +see why lock test case 7 takes longer to complete to Samba
21531 +than to Windows.
21532 +
21533 +Misc testing to do
21534 +==================
21535 +1) check out max path names and max path name components against various server
21536 +types. Try nested symlinks. Return max path name in stat -f information
21537 +
21538 +2) Modify file portion of ltp so it can run against a mounted network
21539 +share and run it against cifs vfs.
21540 +
21541 +3) Additional performance testing and optimization using iozone and similar - 
21542 +there are some easy changes that can be done to parallelize sequential writes,
21543 +and when signing is disabled to request larger read sizes (larger than 
21544 +negotiated size) and send larger write sizes to modern servers.
21545 +
21546 +4) More exhaustively test the recently added NT4 support against various
21547 +NT4 service pack levels.
