2273 For better POSIX semantics from Linux client, (even better
2274 than the existing CIFS Unix Extensions) we need updated PDUs for:
2276 1) PosixCreateX - to set and return the mode, inode#, device info and
2277 perhaps add a CreateDevice - to create Pipes and other special .inodes
2278 Also note POSIX open flags
2279 2) Close - to return the last write time to do cache across close
2281 3) FindFirst return unique inode number - what about resume key, two
2282 forms short (matches readdir) and full (enough info to cache inodes)
2285 And under consideration:
2286 5) FindClose2 (return nanosecond timestamp ??)
2287 6) Use nanosecond timestamps throughout all time fields if
2288 corresponding attribute flag is set
2289 7) sendfile - handle based copy
2293 what about fixing 64 bit alignment
2295 There are also various legacy SMB/CIFS requests used as is
2297 From existing Lanman and NTLM dialects:
2298 --------------------------------------
2300 SESSION_SETUP_ANDX (BB which?)
2301 TREE_CONNECT_ANDX (BB which wct?)
2302 TREE_DISCONNECT (BB add volume timestamp on response)
2304 DELETE (note delete open file behavior)
2308 LOCKING_AND_X (note posix lock semantics)
2309 RENAME (note rename across dirs and open file rename posix behaviors)
2310 NT_RENAME (for hardlinks) Is this good enough for all features?
2312 TRANSACTION2 (18 cases)
2313 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2314 (BB verify that never need to set allocation size)
2315 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2318 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2319 setting/getting OS/2 EAs - FUTURE (BB can this handle
2320 setting Linux xattrs perfectly) - OPTIONAL
2321 dnotify - FUTURE, OPTIONAL
2322 quota - FUTURE, OPTIONAL
2324 Note that various requests implemented for NT interop such as
2325 NT_TRANSACT (IOCTL) QueryReparseInfo
2326 are unneeded to servers compliant with the CIFS POSIX extensions
2328 From CIFS Unix Extensions:
2329 -------------------------
2330 T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
2331 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
2332 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
2333 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) - BB check for missing inode fields
2334 Actually need QUERY_FILE_UNIX_INFO since has inode num
2335 BB what about a) blksize/blkbits/blocks
2341 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
2342 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
2343 T2_QFS_INFO QueryDevice/AttributeInfo - OPTIONAL
