2603 For better POSIX semantics from Linux client, (even better
2604 than the existing CIFS Unix Extensions) we need updated PDUs for:
2605
2606 1) PosixCreateX - to set and return the mode, inode#, device info and
2607 perhaps add a CreateDevice - to create Pipes and other special .inodes
2608 Also note POSIX open flags
2609 2) Close - to return the last write time to do cache across close
2610 more safely
2611 3) FindFirst return unique inode number - what about resume key, two
2612 forms short (matches readdir) and full (enough info to cache inodes)
2613 4) Mkdir - set mode
2614
2615 And under consideration:
2616 5) FindClose2 (return nanosecond timestamp ??)
2617 6) Use nanosecond timestamps throughout all time fields if
2618 corresponding attribute flag is set
2619 7) sendfile - handle based copy
2620
2621 what about fixing 64 bit alignment
2622
2623 There are also various legacy SMB/CIFS requests used as is

2628 SESSION_SETUP_ANDX (BB which?)
2629 TREE_CONNECT_ANDX (BB which wct?)
2630 TREE_DISCONNECT (BB add volume timestamp on response)
2631 LOGOFF_ANDX
2632 DELETE (note delete open file behavior)
2633 DELETE_DIRECTORY
2634 READ_AND_X
2635 WRITE_AND_X
2636 LOCKING_AND_X (note posix lock semantics)
2637 RENAME (note rename across dirs and open file rename posix behaviors)
2638 NT_RENAME (for hardlinks) Is this good enough for all features?
2639 FIND_CLOSE2
2640 TRANSACTION2 (18 cases)
2641 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2642 (BB verify that never need to set allocation size)
2643 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2644 Unix ext?)
2645
2646 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2647 setting/getting OS/2 EAs - FUTURE (BB can this handle
2648 setting Linux xattrs perfectly) - OPTIONAL
2649 dnotify - FUTURE, OPTIONAL
2650 quota - FUTURE, OPTIONAL
