2221 For better POSIX semantics from Linux client, (even better
2222 than the existing CIFS Unix Extensions) we need updated PDUs for:
2224 1) PosixCreateX - to set and return the mode, inode#, device info and
2225 perhaps add a CreateDevice - to create Pipes and other special .inodes
2226 Also note POSIX open flags
2227 2) Close - to return the last write time to do cache across close more safely
2228 3) FindFirst return unique inode number - what about resume key, two
2229 forms short (matches readdir) and full (enough info to cache inodes)
2230 4) Mkdir - set mode
2232 And under consideration:
2233 5) FindClose2 (return nanosecond timestamp ??)
2234 6) Use nanosecond timestamps throughout all time fields if
2235 corresponding attribute flag is set
2236 7) sendfile - handle based copy
2237 8) Direct i/o
2238 9) Misc fcntls?
2240 what about fixing 64 bit alignment
2242 There are also various legacy SMB/CIFS requests used as is
2244 From existing Lanman and NTLM dialects:
2245 --------------------------------------
2246 NEGOTIATE
2247 SESSION_SETUP_ANDX (BB which?)
2248 TREE_CONNECT_ANDX (BB which wct?)
2249 TREE_DISCONNECT (BB add volume timestamp on response)
2250 LOGOFF_ANDX
2251 DELETE (note delete open file behavior)
2252 DELETE_DIRECTORY
2253 READ_AND_X
2254 WRITE_AND_X
2255 LOCKING_AND_X (note posix lock semantics)
2256 RENAME (note rename across dirs and open file rename posix behaviors)
2257 NT_RENAME (for hardlinks) Is this good enough for all features?
2258 FIND_CLOSE2
2259 TRANSACTION2 (18 cases)
2260 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2261 (BB verify that never need to set allocation size)
2262 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via Unix ext?)
2264 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2265 setting/getting OS/2 EAs - FUTURE (BB can this handle
2266 setting Linux xattrs perfectly) - OPTIONAL
2267 dnotify - FUTURE, OPTIONAL
2268 quota - FUTURE, OPTIONAL
2270 Note that various requests implemented for NT interop such as
2271 NT_TRANSACT (IOCTL) QueryReparseInfo
2272 are unneeded to servers compliant with the CIFS POSIX extensions
2274 From CIFS Unix Extensions:
2275 -------------------------

2277 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
2278 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
2279 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) - BB check for missing inode fields
2280 Actually need QUERY_FILE_UNIX_INFO since has inode num
2281 BB what about a) blksize/blkbits/blocks
2282 b) i_version
2283 c) i_rdev
2284 d) notify mask?
2285 e) generation
2286 f) size_seqcount
2287 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
2288 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
