481 * The Naming convention is the lower case version of the
482 * smb command code name for the struct and this is typedef to the
483 * uppercase version of the same name with the prefix SMB_ removed
484 * for brevity. Although typedefs are not commonly used for
485 * structure definitions in the Linux kernel, their use in the
486 * CIFS standards document, which this code is based on, may
487 * make this one of the cases where typedefs for structures make
488 * sense to improve readability for readers of the standards doc.
489 * Typedefs can always be removed later if they are too distracting
490 * and they are only used for the CIFSs PDUs themselves, not
491 * internal cifs vfs structures

2624 For better POSIX semantics from Linux client, (even better
2625 than the existing CIFS Unix Extensions) we need updated PDUs for:
2626
2627 1) PosixCreateX - to set and return the mode, inode#, device info and
2628 perhaps add a CreateDevice - to create Pipes and other special .inodes
2629 Also note POSIX open flags
2630 2) Close - to return the last write time to do cache across close
2631 more safely
2632 3) FindFirst return unique inode number - what about resume key, two
2633 forms short (matches readdir) and full (enough info to cache inodes)
2634 4) Mkdir - set mode
2635
2636 And under consideration:
2637 5) FindClose2 (return nanosecond timestamp ??)
2638 6) Use nanosecond timestamps throughout all time fields if
2639 corresponding attribute flag is set
2640 7) sendfile - handle based copy
2641
2642 what about fixing 64 bit alignment
2643
2644 There are also various legacy SMB/CIFS requests used as is
2645
2646 From existing Lanman and NTLM dialects:

2648 NEGOTIATE
2649 SESSION_SETUP_ANDX (BB which?)
2650 TREE_CONNECT_ANDX (BB which wct?)
2651 TREE_DISCONNECT (BB add volume timestamp on response)
2652 LOGOFF_ANDX
2653 DELETE (note delete open file behavior)
2654 DELETE_DIRECTORY
2655 READ_AND_X
2656 WRITE_AND_X
2657 LOCKING_AND_X (note posix lock semantics)
2658 RENAME (note rename across dirs and open file rename posix behaviors)
2659 NT_RENAME (for hardlinks) Is this good enough for all features?
2660 FIND_CLOSE2
2661 TRANSACTION2 (18 cases)
2662 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2663 (BB verify that never need to set allocation size)
2664 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2665 Unix ext?)
2666
2667 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2668 setting/getting OS/2 EAs - FUTURE (BB can this handle
2669 setting Linux xattrs perfectly) - OPTIONAL
2670 dnotify - FUTURE, OPTIONAL
2671 quota - FUTURE, OPTIONAL
2672
2673 Note that various requests implemented for NT interop such as
2674 NT_TRANSACT (IOCTL) QueryReparseInfo
2675 are unneeded to servers compliant with the CIFS POSIX extensions
