2459 perhaps add a CreateDevice - to create Pipes and other special .inodes
2460 Also note POSIX open flags
2461 2) Close - to return the last write time to do cache across close
2462 more safely
2463 3) FindFirst return unique inode number - what about resume key, two
2464 forms short (matches readdir) and full (enough info to cache inodes)
2465 4) Mkdir - set mode
2466
2467 And under consideration:
2468 5) FindClose2 (return nanosecond timestamp ??)
2469 6) Use nanosecond timestamps throughout all time fields if
2470 corresponding attribute flag is set
2471 7) sendfile - handle based copy

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