2625 For better POSIX semantics from Linux client, (even better
2626 than the existing CIFS Unix Extensions) we need updated PDUs for:
2628 1) PosixCreateX - to set and return the mode, inode#, device info and
2629 perhaps add a CreateDevice - to create Pipes and other special .inodes
2630 Also note POSIX open flags
2631 2) Close - to return the last write time to do cache across close
2633 3) FindFirst return unique inode number - what about resume key, two
2634 forms short (matches readdir) and full (enough info to cache inodes)
2637 And under consideration:
2638 5) FindClose2 (return nanosecond timestamp ??)
2639 6) Use nanosecond timestamps throughout all time fields if
2640 corresponding attribute flag is set
2641 7) sendfile - handle based copy
2643 what about fixing 64 bit alignment
2645 There are also various legacy SMB/CIFS requests used as is
2647 From existing Lanman and NTLM dialects:
2648 --------------------------------------
2650 SESSION_SETUP_ANDX (BB which?)
2651 TREE_CONNECT_ANDX (BB which wct?)
2652 TREE_DISCONNECT (BB add volume timestamp on response)
2654 DELETE (note delete open file behavior)
2658 LOCKING_AND_X (note posix lock semantics)
2659 RENAME (note rename across dirs and open file rename posix behaviors)
2660 NT_RENAME (for hardlinks) Is this good enough for all features?
2662 TRANSACTION2 (18 cases)
2663 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2664 (BB verify that never need to set allocation size)
2665 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2668 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2669 setting/getting OS/2 EAs - FUTURE (BB can this handle
2670 setting Linux xattrs perfectly) - OPTIONAL
2671 dnotify - FUTURE, OPTIONAL
2672 quota - FUTURE, OPTIONAL
2674 Note that various requests implemented for NT interop such as
2675 NT_TRANSACT (IOCTL) QueryReparseInfo
2676 are unneeded to servers compliant with the CIFS POSIX extensions
2678 From CIFS Unix Extensions:
2679 -------------------------
2680 T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
2681 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
2682 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
2683 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) BB check for missing
2685 Actually a need QUERY_FILE_UNIX_INFO
2687 BB what about a) blksize/blkbits/blocks
2693 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
2694 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
2695 T2_QFS_INFO QueryDevice/AttributeInfo - OPTIONAL
