2532 For better POSIX semantics from Linux client, (even better
2533 than the existing CIFS Unix Extensions) we need updated PDUs for:
2534
2535 1) PosixCreateX - to set and return the mode, inode#, device info and
2536 perhaps add a CreateDevice - to create Pipes and other special .inodes
2537 Also note POSIX open flags
2538 2) Close - to return the last write time to do cache across close
2539 more safely
2540 3) FindFirst return unique inode number - what about resume key, two
2541 forms short (matches readdir) and full (enough info to cache inodes)
2542 4) Mkdir - set mode
2543
2544 And under consideration:
2545 5) FindClose2 (return nanosecond timestamp ??)
2546 6) Use nanosecond timestamps throughout all time fields if
2547 corresponding attribute flag is set
2548 7) sendfile - handle based copy
2549
2550 what about fixing 64 bit alignment
2551
2552 There are also various legacy SMB/CIFS requests used as is
2553
2554 From existing Lanman and NTLM dialects:

2556 NEGOTIATE
2557 SESSION_SETUP_ANDX (BB which?)
2558 TREE_CONNECT_ANDX (BB which wct?)
2559 TREE_DISCONNECT (BB add volume timestamp on response)
2560 LOGOFF_ANDX
2561 DELETE (note delete open file behavior)
2562 DELETE_DIRECTORY
2563 READ_AND_X
2564 WRITE_AND_X
2565 LOCKING_AND_X (note posix lock semantics)
2566 RENAME (note rename across dirs and open file rename posix behaviors)
2567 NT_RENAME (for hardlinks) Is this good enough for all features?
2568 FIND_CLOSE2
2569 TRANSACTION2 (18 cases)
2570 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2571 (BB verify that never need to set allocation size)
2572 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2573 Unix ext?)
2574
2575 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2576 setting/getting OS/2 EAs - FUTURE (BB can this handle
2577 setting Linux xattrs perfectly) - OPTIONAL
2578 dnotify - FUTURE, OPTIONAL
2579 quota - FUTURE, OPTIONAL
2580
2581 Note that various requests implemented for NT interop such as
2582 NT_TRANSACT (IOCTL) QueryReparseInfo
2583 are unneeded to servers compliant with the CIFS POSIX extensions

2594 BB what about a) blksize/blkbits/blocks
