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
26 + For more information see the project page at
27 + http://us1.samba.org/samba/Linux_CIFS_client.html

29 +CIFS Debugging
30 +CONFIG_CIFS_DEBUG
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.

55 + This is the client VFS module for the Common Internet File System
56 + (CIFS) protocol which is the successor to the Server Message Block
57 + (SMB) protocol, the native file sharing mechanism for most early
58 + PC operating systems. CIFS is fully supported by current network
59 + file servers such as Windows 2000, Windows 2003 (including
60 + Windows XP) as well by Samba (which provides excellent CIFS
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

769 +Version 1.20
770 +------------
771 +Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
772 +info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
773 +(in build_wildcard_path_from_dentry). Fix mknod to pass type field
774 +(block/char/fifo) properly. Remove spurious mount warning log entry when
775 +credentials passed as mount argument. Set major/minor device number in
776 +inode for block and char devices when unix extensions enabled.
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
785 +of the two user's smb sessions is being removed while leaving the other.
786 +Do not loop reconnecting in cifsd demultiplex thread when admin
787 +kills the thread without going through unmount.
788 +
789 +Version 1.18
790 +------------
791 +Do not rename hardlinked files (since that should be a noop). Flush
792 +cached write behind data when reopening a file after session abend,
793 +except when already in write. Grab per socket sem during reconnect
794 +to avoid oops in sendmsg if overlapping with reconnect. Do not
795 +reset cached inode file size on readdir for files open for write on
796 +client.
797 +
798 +
799 +Version 1.17
800 +------------
801 +Update number of blocks in file so du command is happier (in Linux a fake
802 +blocksize of 512 is required for calculating number of blocks in inode).
803 +Fix prepare write of partial pages to read in data from server if possible.
804 +Fix race on tcpStatus field between unmount and reconnection code, causing
805 +cifsd process sometimes to hang around forever. Improve out of memory
806 +checks in cifs_filldir
807 +
808 +Version 1.16
809 +------------
810 +Fix incorrect file size in file handle based setattr on big endian hardware.
811 +Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
812 +and closing file structs in writepage/partialpagewrite. Add statistics
813 +for each mounted share (new menuconfig option). Fix endianness problem in
814 +volume information displayed in /proc/fs/cifs/DebugData (only affects
815 +affects big endian architectures). Prevent renames while constructing
816 +path names for open, mkdir and rmdir.
817 +
818 +Version 1.15
819 +------------
820 +Change to mempools for alloc smb request buffers and multiplex structs
821 +to better handle low memory problems (and potential deadlocks).
822 +
823 +Version 1.14
824 +------------
825 +Fix incomplete listings of large directories on Samba servers when Unix
826 +extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
827 +rename deadlock when writing out dirty pages at same time.
828 +
829 +Version 1.13
830 +------------
831 +Fix open of files in which O_CREATE can cause the mode to change in
832 +some cases. Fix case in which retry of write overlaps file close.
833 +Fix PPC64 build error. Reduce excessive stack usage in smb password
834 +hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
835 +
836 +Version 1.12
837 +------------
838 +Fixes for large file copy, signal handling, socket retry, buffer
839 +allocation and low memory situations.
840 +
841 +Version 1.11
842 +------------
843 +Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
844 +also now allowing support for specifying client netbiosname. NT4 support added.
845 +
846 +Version 1.10
847 +------------
848 +Fix reconnection (and certain failed mounts) to properly wake up the
849 +blocked users thread so it does not seem hung (in some cases was blocked
850 +until the cifs receive timeout expired). Fix spurious error logging
851 +to kernel log when application with open network files killed.
852 +
853 +Version 1.09
854 +------------
855 +Fix /proc/fs module unload warning message (that could be logged
856 +to the kernel log). Fix intermittent failure in connectathon
857 +test7 (hardlink count not immediately refreshed in case in which
858 +inode metadata can be incorrectly kept cached when time near zero)
859 +
860 +Version 1.08
861 +------------
862 +Allow file_mode and dir_mode (specified at mount time) to be enforced
863 +locally (the server already enforced its own ACLs too) for servers
864 +that do not report the correct mode (do not support the
865 +CIFS Unix Extensions).
866 +
867 +Version 1.07
868 +------------
869 +Fix some small memory leaks in some unmount error paths. Fix major leak
870 +of cache pages in readpages causing multiple read oriented stress
871 +testcases (including fsx, and even large file copy) to fail over time.
872 +
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
879 +break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
880 +
881 +Version 1.05
882 +------------
883 +fixes to cifs_readpages for fsx test case
884 +
885 +Version 1.04
886 +------------
887 +Fix caching data integrity bug when extending file size especially when no
888 +oplock on file. Fix spurious logging of valid already parsed mount options
889 +that are parsed outside of the cifs vfs such as nosuid.
890 +
891 +
892 +Version 1.03
893 +------------
894 +Connect to server when port number override not specified, and tcp port
895 +unitialized. Reset search to restart at correct file when kernel routine
896 +filldir returns error during large directory searches (readdir).
897 +
898 +Version 1.02
899 +------------
900 +Fix caching problem when files opened by multiple clients in which
901 +page cache could contain stale data, and write through did
902 +not occur often enough while file was still open when read ahead
903 +(read oplock) not allowed. Treat "sep=" when first mount option
904 +as an overrride of comma as the default separator between mount
905 +options.
906 +
907 +Version 1.01
908 +------------
909 +Allow passwords longer than 16 bytes. Allow null password string.
910 +
911 +Version 1.00
912 +------------
913 +Gracefully clean up failed mounts when attempting to mount to servers such as
914 +Windows 98 that terminate tcp sessions during prototocol negotiation. Handle
915 +embedded commas in mount parsing of passwords.
916 +
917 +Version 0.99
918 +------------
919 +Invalidate local inode cached pages on oplock break and when last file
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
924 +the support for CIFS Unix Extensions to be disabled via proc interface.
925 +
926 +Version 0.98
927 +------------
928 +Fix hang in commit_write during reconnection of open files under heavy load.
929 +Fix unload_nls oops in a mount failure path. Serialize writes to same socket
930 +which also fixes any possible races when cifs signatures are enabled in SMBs
931 +being sent out of signature sequence number order.
932 +
933 +Version 0.97
934 +------------
935 +Fix byte range locking bug (endian problem) causing bad offset and
936 +length.
937 +
938 +Version 0.96
939 +------------
940 +Fix oops (in send_sig) caused by CIFS unmount code trying to
941 +wake up the demultiplex thread after it had exited. Do not log
942 +error on harmless oplock release of closed handle.
943 +
944 +Version 0.95
945 +------------
946 +Fix unsafe global variable usage and password hash failure on gcc 3.3.1
947 +Fix problem reconnecting secondary mounts to same server after session
948 +failure. Fix invalid dentry - race in mkdir when directory gets created
949 +by another client between the lookup and mkdir.
950 +
951 +Version 0.94
952 +------------
953 +Fix to list processing in reopen_files. Fix reconnection when server hung
954 +but tcpip session still alive. Set proper timeout on socket read.
955 +
956 +Version 0.93
957 +------------
958 +Add missing mount options including iocharset. SMP fixes in write and open.
959 +Fix errors in reconnecting after TCP session failure. Fix module unloading
960 +of default nls codepage
961 +
962 +Version 0.92
963 +------------
964 +Active smb transactions should never go negative (fix double FreeXid). Fix
965 +list processing in file routines. Check return code on kmalloc in open.
966 +Fix spinlock usage for SMP.
967 +
968 +Version 0.91
969 +------------
970 +Fix oops in reopen_files when invalid dentry. drop dentry on server rename
971 +and on revalidate errors. Fix cases where pid is now tgid. Fix return code
972 +on create hard link when server does not support them.
973 +
974 +Version 0.90
975 +------------
976 +Fix scheduling while atomic error in getting inode info on newly created file.
977 +Fix truncate of existing files opened with O_CREAT but not O_TRUNC set.
978 +
979 +Version 0.89
980 +------------
981 +Fix oops on write to dead tcp session. Remove error log write for case when file open
982 +O_CREAT but not O_EXCL
983 +
984 +Version 0.88
985 +------------
986 +Fix non-POSIX behavior on rename of open file and delete of open file by taking
987 +advantage of trans2 SetFileInfo rename facility if available on target server.
988 +Retry on ENOSPC and EAGAIN socket errors.
989 +
990 +Version 0.87
991 +------------
992 +Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix
993 +allocation size miscalculation. After oplock token lost do not read through
994 +cache.
995 +
996 +Version 0.86
997 +------------
998 +Fix oops on empty file readahead. Fix for file size handling for locally cached files.

1003 +during auto reconnection to server after server recovered from failure.
1004 +
1005 +Version 0.84
1006 +------------
1007 +Finish support for Linux 2.5 open/create changes, which removes the
1008 +redundant NTCreate/QPathInfo/close that was sent during file create.
1009 +Enable oplock by default. Enable packet signing by default (needed to
1010 +access many recent Windows servers)
1011 +
1012 +Version 0.83
1013 +------------
1014 +Fix oops when mounting to long server names caused by inverted parms to kmalloc.
1015 +Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
1016 +we will choose a cifs user session (smb uid) that better matches the local
1017 +uid if a) the mount uid does not match the current uid and b) we have another
1018 +session to the same server (ip address) for a different mount which
1019 +matches the current local uid.

1021 +Version 0.82
1022 +------------
1023 +Add support for mknod of block or character devices. Fix oplock
1024 +code (distributed caching) to properly send response to oplock
1025 +break from server.
1026 +
1027 +Version 0.81
1028 +------------
1029 +Finish up CIFS packet digital signing for the default
1030 +NTLM security case. This should help Windows 2003
1031 +network interoperability since it is common for
1032 +packet signing to be required now. Fix statfs (stat -f)
1033 +which recently started returning errors due to
1034 +invalid value (-1 instead of 0) being set in the
1035 +struct kstatfs f_ffiles field.
1036 +
1037 +Version 0.80
1038 +-----------
1039 +Fix oops on stopping oplock thread when removing cifs when
1040 +built as module.

1053 +Fix display of NTFS DFS junctions to display as symlinks.
1054 +They are the network equivalent. Fix oops in
1055 +cifs_partialpagewrite caused by missing spinlock protection
1056 +of openfile linked list. Allow writebehind caching errors to
1057 +be returned to the application at file close.
1058 +
1059 +Version 0.76
1060 +------------
1061 +Clean up options displayed in /proc/mounts by show_options to
1062 +be more consistent with other filesystems.
1063 +
1064 +Version 0.75
1065 +------------
1066 +Fix delete of readonly file to Windows servers. Reflect
1067 +presence or absence of read only dos attribute in mode
1068 +bits for servers that do not support CIFS Unix extensions.
1069 +Fix shortened results on readdir of large directories to
1070 +servers supporting CIFS Unix extensions (caused by
1071 +incorrect resume key).
1072 +
1073 +Version 0.74
1074 +------------
1075 +Fix truncate bug (set file size) that could cause hangs e.g. running fsx
1076 +
1077 +Version 0.73
1078 +------------
1079 +unload nls if mount fails.
1080 +
1081 +Version 0.72
1082 +------------

1089 +------------
1090 +Add more oplock handling (distributed caching code). Remove
1091 +dead code. Remove excessive stack space utilization from
1092 +symlink routines.
1093 +
1094 +Version 0.70
1095 +------------
1096 +Fix oops in get dfs referral (triggered when null path sent in to
1097 +mount). Add support for overriding rsize at mount time.
1098 +
1099 +Version 0.69
1100 +------------
1101 +Fix buffer overrun in readdir which caused intermittent kernel oopses.
1102 +Fix writepage code to release kmap on write data. Allow "-ip=" new
1103 +mount option to be passed in on parameter distinct from the first part
1104 +(server name portion of) the UNC name. Allow override of the
1105 +tcp port of the target server via new mount option "-port="
1106 +
1107 +Version 0.68
1108 +------------
1109 +Fix search handle leak on rewind. Fix setuid and gid so that they are
1110 +reflected in the local inode immediately. Cleanup of whitespace
1111 +to make 2.4 and 2.5 versions more consistent.
1112 +
1113 +
1114 +Version 0.67
1115 +------------
1116 +Fix signal sending so that captive thread (cifsd) exits on umount
1117 +(which was causing the warning in kmem_cache_free of the request buffers
1118 +at rmmod time). This had broken as a sideeffect of the recent global
1119 +kernel change to daemonize. Fix memory leak in readdir code which
1120 +showed up in "ls -R" (and applications that did search rewinding).
1121 +
1122 +Version 0.66
1123 +------------
1124 +Reconnect tids and fids after session reconnection (still do not
1125 +reconnect byte range locks though). Fix problem caching
1126 +lookup information for directory inodes, improving performance,
1127 +especially in deep directory trees. Fix various build warnings.
1128 +
1129 +Version 0.65
1130 +------------
1131 +Finish fixes to commit write for caching/readahead consistency. fsx
1132 +now works to Samba servers. Fix oops caused when readahead
1133 +was interrupted by a signal.
1134 +
1135 +Version 0.64
1136 +------------
1137 +Fix data corruption (in partial page after truncate) that caused fsx to
1138 +fail to Windows servers. Cleaned up some extraneous error logging in
1139 +common error paths. Add generic sendfile support.
1140 +
1141 +Version 0.63
1142 +------------
1143 +Fix memory leak in AllocMidQEntry.
1144 +Finish reconnection logic, so connection with server can be dropped
1145 +(or server rebooted) and the cifs client will reconnect.
1146 +
1147 +Version 0.62
1148 +------------
1149 +Fix temporary socket leak when bad userid or password specified
1150 +(or other SMBSessSetup failure). Increase maximum buffer size to slightly
1151 +over 16K to allow negotiation of up to Samba and Windows server default read
1152 +sizes. Add support for readpages
1153 +
1154 +Version 0.61
1155 +------------
1156 +Fix oops when username not passed in on mount. Extensive fixes and improvements
1157 +to error logging (strip redundant newlines, change debug macros to ensure newline
1158 +passed in and to be more consistent). Fix writepage wrong file handle problem,
1159 +a readonly file handle could be incorrectly used to attempt to write out
1160 +file updates through the page cache to multiply open files. This could cause
1161 +the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
1162 +shares to the same Windows server when using different usernames
1163 +(doing this to Samba servers worked but Windows was rejecting it) - now it is
1164 +possible to use different userids when connecting to the same server from a
1165 +Linux client. Fix oops when treeDisconnect called during unmount on
1166 +previously freed socket.
1167 +
1168 +Version 0.60
1169 +------------
1170 +Fix oops in readpages caused by not setting address space operations in inode in
1171 +rare code path.
1172 +
1173 +Version 0.59
1174 +------------
1175 +Includes support for deleting of open files and renaming over existing files (per POSIX
1176 +requirement). Add readlink support for Windows junction points (directory symlinks).
1177 +
1178 +Version 0.58

1181 +Memory mapped operations now working.
1182 +
1183 +Version 0.57
1184 +------------
1185 +Added writepage code for additional memory mapping support. Fixed leak in xids causing
1186 +the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
1187 +every stat call. Additional formatting cleanup.
1188 +
1189 +Version 0.56
1190 +------------
1191 +Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
1192 +
1193 +Version 0.55
1194 +------------
1195 +Fixes from Zwane Mwaikambo for adding missing return code checking in a few places.

1197 +the smb session and tree connection and mid related global variables.
1198 +
1199 +Version 0.54
1200 +------------
1201 +Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
1202 +changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
1203 +buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
1204 +
1205 +Version 0.53
1206 +------------
1207 +More stylistic updates to better match kernel style. Add additional statistics
1208 +for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
1209 +and CIFS Packet Signing enablement.
1210 +
1211 +Version 0.52
1212 +------------
1213 +Replace call to sleep_on with safer wait_on_event.
1214 +Make stylistic changes to better match kernel style recommendations.
1215 +Remove most typedef usage (except for the PDUs themselves).
1216 +
1217 +Version 0.51
1218 +------------
1219 +Update mount so the -unc mount option is no longer required (the ip address can be specified
1220 +in a UNC style device name. Implementation of readpage/writepage started.
1221 +
1222 +Version 0.50
1223 +------------
1224 +Fix intermittent problem with incorrect smb header checking on badly
1225 +fragmented tcp responses

1248 +------------
1249 +Various big endian fixes for servers with Unix extensions such as Samba
1250 +
1251 +Version 0.43
1252 +------------

1254 +clients. basic posix file i/o tests now work on big endian machines, not just le
1255 +
1256 +Version 0.42
1257 +------------
1258 +SessionSetup and NegotiateProtocol now work from Big Endian machines.
1259 +Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older
1260 +versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7).
1261 +
1262 +Version 0.41
1263 +------------
1264 +Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
1265 +files now return the correct rumber of links on fstat as they are repeatedly linked and unlinked.
1266 +
1267 +Version 0.40
1268 +------------
1269 +Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
1270 +session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
1271 +Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
1272 +(which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).
1273 +
1274 +Version 0.38
1275 +------------
1276 +Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
1277 +it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
1278 +
1279 +Version 0.37
1280 +------------
1281 +Rewrote much of connection and mount/unmount logic to handle bugs with
1282 +multiple uses to same share, multiple users to same server etc.
1283 +
1284 +Version 0.36
1285 +------------
1286 +Fixed major problem with dentry corruption (missing call to dput)
1287 +
1288 +Version 0.35
1289 +------------
1290 +Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
1291 +Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
1292 +although corresponding function not fully implemented in the vfs yet
1293 +
1294 +Version 0.34
1295 +------------
1296 +Fixed dentry caching bug, misc. cleanup
1297 +
1298 +Version 0.33
1299 +------------
1300 +Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
1301 +on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
1302 +Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
1303 +
1304 +Version 0.32
1305 +------------
1306 +Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
1307 +and tested against Samba 2.2.5
1308 +
1309 +
1310 +Version 0.31
1311 +------------
1312 +1) Fixed lockrange to be correct (it was one byte too short)
1313 +
1314 +2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
1315 +show range as locked when there is a conflict with an existing lock.
1316 +
1317 +3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
1318 +in most cases. Eventually will offer optional ability to query server for the correct perms.
1319 +
1320 +3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
1321 +but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
1322 +session)
1323 +
1324 +4) Fixed error logging of valid mount options
1325 +
1326 +5) Removed logging of password field.
1327 +
1328 +6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
1329 +and cleaned them up and made them more consistent with other cifs functions.
1330 +
1331 +7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
1332 +(with or without Unix exentions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
1333 +nor is the symlink support using the Unix extensions
1334 +
1335 +8) Started adding the readlink and follow_link code
1336 +
1337 +Version 0.3

5540 + For better POSIX semantics from Linux client, (even better
5541 + than the existing CIFS Unix Extensions) we need updated PDUs for:
5542 +
5543 + 1) PosixCreateX - to set and return the mode, inode#, device info and
5544 + perhaps add a CreateDevice - to create Pipes and other special .inodes
5545 + Also note POSIX open flags
5546 + 2) Close - to return the last write time to do cache across close more safely
5547 + 3) PosixQFSInfo - to return statfs info
5548 + 4) FindFirst return unique inode number - what about resume key, two forms short (matches readdir) and full (enough info to cache inodes)
5549 + 5) Mkdir - set mode
5550 +
5551 + And under consideration:
5552 + 6) FindClose2 (return nanosecond timestamp ??)
5553 + 7) Use nanosecond timestamps throughout all time fields if
5554 + corresponding attribute flag is set
5555 + 8) sendfile - handle based copy
5556 + 9) Direct i/o
5557 + 10) "POSIX ACL" support
5558 + 11) Misc fcntls?
5559 +
5560 + what about fixing 64 bit alignment
5561 +
5562 + There are also various legacy SMB/CIFS requests used as is
5563 +
5564 + From existing Lanman and NTLM dialects:
5565 + --------------------------------------
5566 + NEGOTIATE
5567 + SESSION_SETUP_ANDX (BB which?)
5568 + TREE_CONNECT_ANDX (BB which wct?)
5569 + TREE_DISCONNECT (BB add volume timestamp on response)
5570 + LOGOFF_ANDX
5571 + DELETE (note delete open file behavior)
5572 + DELETE_DIRECTORY
5573 + READ_AND_X
5574 + WRITE_AND_X
5575 + LOCKING_AND_X (note posix lock semantics)
5576 + RENAME (note rename across dirs and open file rename posix behaviors)
5577 + NT_RENAME (for hardlinks) Is this good enough for all features?
5578 + FIND_CLOSE2
5579 + TRANSACTION2 (18 cases)
5580 + SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
5581 + (BB verify that never need to set allocation size)
5582 + SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via Unix ext?)
5583 +
5584 + COPY (note support for copy across directories) - FUTURE, OPTIONAL
5585 + setting/getting OS/2 EAs - FUTURE (BB can this handle
5586 + setting Linux xattrs perfectly) - OPTIONAL
5587 + dnotify - FUTURE, OPTIONAL
5588 + quota - FUTURE, OPTIONAL
5589 +
5590 + Note that various requests implemented for NT interop such as
5591 + NT_TRANSACT (IOCTL) QueryReparseInfo
5592 + are unneeded to servers compliant with the CIFS POSIX extensions
5593 +
5594 + From CIFS Unix Extensions:
5595 + -------------------------
5596 + T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
5597 + T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
5598 + T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
5599 + T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) - BB check for missing inode fields
5600 + Actually need QUERY_FILE_UNIX_INFO since has inode num
5601 + BB what about a) blksize/blkbits/blocks
5602 + b) i_version
5603 + c) i_rdev
5604 + d) notify mask?
5605 + e) generation
5606 + f) size_seqcount
5607 + T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
5608 + TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
5609 + T2_QFS_INFO QueryDevice/AttributeInfo - OPTIONAL

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
19932 +practical interoperability with Windows 2000, Windows XP, Samba and equivalent
19933 +servers.

19935 +For questions or bug reports please contact:
19936 + sfrench@samba.org (sfrench@us.ibm.com)
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.
20111 + domain Set the SMB/CIFS workgroup name prepended to the
20112 + username during CIFS session establishment
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
20151 + wsize default write size
20152 + rw mount the network share read-write (note that the
20153 + server may still consider the share read-only)
20154 + ro mount network share read-only
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

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).

20397 +
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

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.
