2533 For better POSIX semantics from Linux client, (even better
2534 than the existing CIFS Unix Extensions) we need updated PDUs for:
2535
2536 1) PosixCreateX - to set and return the mode, inode#, device info and
2537 perhaps add a CreateDevice - to create Pipes and other special .inodes
2538 Also note POSIX open flags
2539 2) Close - to return the last write time to do cache across close
2540 more safely
2541 3) FindFirst return unique inode number - what about resume key, two
2542 forms short (matches readdir) and full (enough info to cache inodes)
2543 4) Mkdir - set mode
2544
2545 And under consideration:
2546 5) FindClose2 (return nanosecond timestamp ??)
2547 6) Use nanosecond timestamps throughout all time fields if
2548 corresponding attribute flag is set
2549 7) sendfile - handle based copy
2550
2551 what about fixing 64 bit alignment
2552
2553 There are also various legacy SMB/CIFS requests used as is
2554
2555 From existing Lanman and NTLM dialects:
2556 --------------------------------------
2557 NEGOTIATE
2558 SESSION_SETUP_ANDX (BB which?)
2559 TREE_CONNECT_ANDX (BB which wct?)
2560 TREE_DISCONNECT (BB add volume timestamp on response)
2561 LOGOFF_ANDX
2562 DELETE (note delete open file behavior)
2563 DELETE_DIRECTORY
2564 READ_AND_X
2565 WRITE_AND_X
2566 LOCKING_AND_X (note posix lock semantics)
2567 RENAME (note rename across dirs and open file rename posix behaviors)
2568 NT_RENAME (for hardlinks) Is this good enough for all features?
2569 FIND_CLOSE2
2570 TRANSACTION2 (18 cases)
2571 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2572 (BB verify that never need to set allocation size)
2573 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2574 Unix ext?)
2575
2576 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2577 setting/getting OS/2 EAs - FUTURE (BB can this handle
2578 setting Linux xattrs perfectly) - OPTIONAL
2579 dnotify - FUTURE, OPTIONAL
2580 quota - FUTURE, OPTIONAL
2581
2582 Note that various requests implemented for NT interop such as
2583 NT_TRANSACT (IOCTL) QueryReparseInfo
2584 are unneeded to servers compliant with the CIFS POSIX extensions

2591 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) BB check for missing
2592 inode fields
2593 Actually a need QUERY_FILE_UNIX_INFO
2594 since has inode num
2595 BB what about a) blksize/blkbits/blocks
2596 b) i_version
2597 c) i_rdev
2598 d) notify mask?
2599 e) generation
