2655 For better POSIX semantics from Linux client, (even better
2656 than the existing CIFS Unix Extensions) we need updated PDUs for:
2657
2658 1) PosixCreateX - to set and return the mode, inode#, device info and
2659 perhaps add a CreateDevice - to create Pipes and other special .inodes
2660 Also note POSIX open flags
2661 2) Close - to return the last write time to do cache across close
2662 more safely
2663 3) FindFirst return unique inode number - what about resume key, two
2664 forms short (matches readdir) and full (enough info to cache inodes)
2665 4) Mkdir - set mode
2666
2667 And under consideration:
2668 5) FindClose2 (return nanosecond timestamp ??)
2669 6) Use nanosecond timestamps throughout all time fields if
2670 corresponding attribute flag is set
2671 7) sendfile - handle based copy
2672
2673 what about fixing 64 bit alignment
2674
2675 There are also various legacy SMB/CIFS requests used as is
2676
2677 From existing Lanman and NTLM dialects:

2679 NEGOTIATE
2680 SESSION_SETUP_ANDX (BB which?)
2681 TREE_CONNECT_ANDX (BB which wct?)
2682 TREE_DISCONNECT (BB add volume timestamp on response)
2683 LOGOFF_ANDX
2684 DELETE (note delete open file behavior)
2685 DELETE_DIRECTORY
2686 READ_AND_X
2687 WRITE_AND_X
2688 LOCKING_AND_X (note posix lock semantics)
2689 RENAME (note rename across dirs and open file rename posix behaviors)
2690 NT_RENAME (for hardlinks) Is this good enough for all features?
2691 FIND_CLOSE2
2692 TRANSACTION2 (18 cases)
2693 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2694 (BB verify that never need to set allocation size)
2695 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2696 Unix ext?)
2697
2698 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2699 setting/getting OS/2 EAs - FUTURE (BB can this handle
2700 setting Linux xattrs perfectly) - OPTIONAL
2701 dnotify - FUTURE, OPTIONAL
2702 quota - FUTURE, OPTIONAL
2703
2704 Note that various requests implemented for NT interop such as
2705 NT_TRANSACT (IOCTL) QueryReparseInfo
2706 are unneeded to servers compliant with the CIFS POSIX extensions

2717 BB what about a) blksize/blkbits/blocks
