2331 For better POSIX semantics from Linux client, (even better
2332 than the existing CIFS Unix Extensions) we need updated PDUs for:
2334 1) PosixCreateX - to set and return the mode, inode#, device info and
2335 perhaps add a CreateDevice - to create Pipes and other special .inodes
2336 Also note POSIX open flags
2337 2) Close - to return the last write time to do cache across close
2339 3) FindFirst return unique inode number - what about resume key, two
2340 forms short (matches readdir) and full (enough info to cache inodes)
2343 And under consideration:
2344 5) FindClose2 (return nanosecond timestamp ??)
2345 6) Use nanosecond timestamps throughout all time fields if
2346 corresponding attribute flag is set
2347 7) sendfile - handle based copy
2351 what about fixing 64 bit alignment
2353 There are also various legacy SMB/CIFS requests used as is
2355 From existing Lanman and NTLM dialects:
2356 --------------------------------------
2358 SESSION_SETUP_ANDX (BB which?)
2359 TREE_CONNECT_ANDX (BB which wct?)
2360 TREE_DISCONNECT (BB add volume timestamp on response)
2362 DELETE (note delete open file behavior)
2366 LOCKING_AND_X (note posix lock semantics)
2367 RENAME (note rename across dirs and open file rename posix behaviors)
2368 NT_RENAME (for hardlinks) Is this good enough for all features?
2370 TRANSACTION2 (18 cases)
2371 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2372 (BB verify that never need to set allocation size)
2373 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2376 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2377 setting/getting OS/2 EAs - FUTURE (BB can this handle
2378 setting Linux xattrs perfectly) - OPTIONAL
2379 dnotify - FUTURE, OPTIONAL
2380 quota - FUTURE, OPTIONAL
2382 Note that various requests implemented for NT interop such as
2383 NT_TRANSACT (IOCTL) QueryReparseInfo
2384 are unneeded to servers compliant with the CIFS POSIX extensions
2386 From CIFS Unix Extensions:
2387 -------------------------

2389 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
