2520 For better POSIX semantics from Linux client, (even better
2521 than the existing CIFS Unix Extensions) we need updated PDUs for:
2522
2523 1) PosixCreateX - to set and return the mode, inode#, device info and
2524 perhaps add a CreateDevice - to create Pipes and other special .inodes
2525 Also note POSIX open flags
2526 2) Close - to return the last write time to do cache across close
2527 more safely
2528 3) FindFirst return unique inode number - what about resume key, two
2529 forms short (matches readdir) and full (enough info to cache inodes)
2530 4) Mkdir - set mode
2531
2532 And under consideration:
2533 5) FindClose2 (return nanosecond timestamp ??)
2534 6) Use nanosecond timestamps throughout all time fields if
2535 corresponding attribute flag is set
2536 7) sendfile - handle based copy
2537
2538 what about fixing 64 bit alignment
2539
2540 There are also various legacy SMB/CIFS requests used as is
2541
2542 From existing Lanman and NTLM dialects:
2543 --------------------------------------
2544 NEGOTIATE
2545 SESSION_SETUP_ANDX (BB which?)
2546 TREE_CONNECT_ANDX (BB which wct?)
2547 TREE_DISCONNECT (BB add volume timestamp on response)
2548 LOGOFF_ANDX
2549 DELETE (note delete open file behavior)
2550 DELETE_DIRECTORY
2551 READ_AND_X
2552 WRITE_AND_X
2553 LOCKING_AND_X (note posix lock semantics)
2554 RENAME (note rename across dirs and open file rename posix behaviors)
2555 NT_RENAME (for hardlinks) Is this good enough for all features?
2556 FIND_CLOSE2
2557 TRANSACTION2 (18 cases)
2558 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2559 (BB verify that never need to set allocation size)
2560 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2561 Unix ext?)
2562
2563 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2564 setting/getting OS/2 EAs - FUTURE (BB can this handle
2565 setting Linux xattrs perfectly) - OPTIONAL
2566 dnotify - FUTURE, OPTIONAL
2567 quota - FUTURE, OPTIONAL
2568
2569 Note that various requests implemented for NT interop such as
2570 NT_TRANSACT (IOCTL) QueryReparseInfo
2571 are unneeded to servers compliant with the CIFS POSIX extensions

2578 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) BB check for missing
2579 inode fields
2580 Actually a need QUERY_FILE_UNIX_INFO
2581 since has inode num
2582 BB what about a) blksize/blkbits/blocks
2583 b) i_version
2584 c) i_rdev
2585 d) notify mask?
2586 e) generation
2587 f) size_seqcount
