2470 6) Use nanosecond timestamps throughout all time fields if
2471 corresponding attribute flag is set
2472 7) sendfile - handle based copy
2473
2474 what about fixing 64 bit alignment
2475
2476 There are also various legacy SMB/CIFS requests used as is
2477
2478 From existing Lanman and NTLM dialects:
2479 --------------------------------------
2480 NEGOTIATE
2481 SESSION_SETUP_ANDX (BB which?)
2482 TREE_CONNECT_ANDX (BB which wct?)
2483 TREE_DISCONNECT (BB add volume timestamp on response)
2484 LOGOFF_ANDX
2485 DELETE (note delete open file behavior)
2486 DELETE_DIRECTORY
2487 READ_AND_X
2488 WRITE_AND_X
2489 LOCKING_AND_X (note posix lock semantics)
2490 RENAME (note rename across dirs and open file rename posix behaviors)
2491 NT_RENAME (for hardlinks) Is this good enough for all features?
2492 FIND_CLOSE2
2493 TRANSACTION2 (18 cases)
2494 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2495 (BB verify that never need to set allocation size)
2496 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2497 Unix ext?)
2498
2499 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2500 setting/getting OS/2 EAs - FUTURE (BB can this handle
2501 setting Linux xattrs perfectly) - OPTIONAL
2502 dnotify - FUTURE, OPTIONAL
2503 quota - FUTURE, OPTIONAL
2504
2505 Note that various requests implemented for NT interop such as
2506 NT_TRANSACT (IOCTL) QueryReparseInfo
2507 are unneeded to servers compliant with the CIFS POSIX extensions
2508
2509 From CIFS Unix Extensions:
2510 -------------------------
2511 T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
2512 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
2513 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
2514 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) BB check for missing
2515 inode fields
2516 Actually a need QUERY_FILE_UNIX_INFO
2517 since has inode num
2518 BB what about a) blksize/blkbits/blocks
2519 b) i_version
2520 c) i_rdev
2521 d) notify mask?
2522 e) generation
2523 f) size_seqcount
2524 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
2525 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
2526 T2_QFS_INFO QueryDevice/AttributeInfo - OPTIONAL
