2256 For better POSIX semantics from Linux client, (even better
2257 than the existing CIFS Unix Extensions) we need updated PDUs for:
2259 1) PosixCreateX - to set and return the mode, inode#, device info and
2260 perhaps add a CreateDevice - to create Pipes and other special .inodes
2261 Also note POSIX open flags
2262 2) Close - to return the last write time to do cache across close
2264 3) FindFirst return unique inode number - what about resume key, two
2265 forms short (matches readdir) and full (enough info to cache inodes)
2268 And under consideration:
2269 5) FindClose2 (return nanosecond timestamp ??)
2270 6) Use nanosecond timestamps throughout all time fields if
2271 corresponding attribute flag is set
2272 7) sendfile - handle based copy
2276 what about fixing 64 bit alignment
2278 There are also various legacy SMB/CIFS requests used as is
2280 From existing Lanman and NTLM dialects:
2281 --------------------------------------
2283 SESSION_SETUP_ANDX (BB which?)
2284 TREE_CONNECT_ANDX (BB which wct?)
2285 TREE_DISCONNECT (BB add volume timestamp on response)
2287 DELETE (note delete open file behavior)
2291 LOCKING_AND_X (note posix lock semantics)
2292 RENAME (note rename across dirs and open file rename posix behaviors)
2293 NT_RENAME (for hardlinks) Is this good enough for all features?
2295 TRANSACTION2 (18 cases)
2296 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2297 (BB verify that never need to set allocation size)
2298 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2301 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2302 setting/getting OS/2 EAs - FUTURE (BB can this handle
2303 setting Linux xattrs perfectly) - OPTIONAL
2304 dnotify - FUTURE, OPTIONAL
2305 quota - FUTURE, OPTIONAL
2307 Note that various requests implemented for NT interop such as
2308 NT_TRANSACT (IOCTL) QueryReparseInfo
2309 are unneeded to servers compliant with the CIFS POSIX extensions
2311 From CIFS Unix Extensions:
2312 -------------------------
2313 T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
2314 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
2315 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
2316 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) - BB check for missing inode fields
2317 Actually need QUERY_FILE_UNIX_INFO since has inode num
2318 BB what about a) blksize/blkbits/blocks
2324 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
2325 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
2326 T2_QFS_INFO QueryDevice/AttributeInfo - OPTIONAL
