2661 For better POSIX semantics from Linux client, (even better
2662 than the existing CIFS Unix Extensions) we need updated PDUs for:
2663
2664 1) PosixCreateX - to set and return the mode, inode#, device info and
2665 perhaps add a CreateDevice - to create Pipes and other special .inodes
2666 Also note POSIX open flags
2667 2) Close - to return the last write time to do cache across close
2668 more safely
2669 3) FindFirst return unique inode number - what about resume key, two
2670 forms short (matches readdir) and full (enough info to cache inodes)
2671 4) Mkdir - set mode
2672
2673 And under consideration:
2674 5) FindClose2 (return nanosecond timestamp ??)
2675 6) Use nanosecond timestamps throughout all time fields if
2676 corresponding attribute flag is set
2677 7) sendfile - handle based copy
2678
2679 what about fixing 64 bit alignment

2686 SESSION_SETUP_ANDX (BB which?)
2687 TREE_CONNECT_ANDX (BB which wct?)
2688 TREE_DISCONNECT (BB add volume timestamp on response)
2689 LOGOFF_ANDX
2690 DELETE (note delete open file behavior)
2691 DELETE_DIRECTORY
2692 READ_AND_X
2693 WRITE_AND_X
2694 LOCKING_AND_X (note posix lock semantics)
2695 RENAME (note rename across dirs and open file rename posix behaviors)
2696 NT_RENAME (for hardlinks) Is this good enough for all features?
2697 FIND_CLOSE2
2698 TRANSACTION2 (18 cases)
2699 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2700 (BB verify that never need to set allocation size)
2701 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2702 Unix ext?)
2703
2704 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2705 setting/getting OS/2 EAs - FUTURE (BB can this handle
2706 setting Linux xattrs perfectly) - OPTIONAL
2707 dnotify - FUTURE, OPTIONAL
2708 quota - FUTURE, OPTIONAL
