2664 For better POSIX semantics from Linux client, (even better
2665 than the existing CIFS Unix Extensions) we need updated PDUs for:
2667 1) PosixCreateX - to set and return the mode, inode#, device info and
2668 perhaps add a CreateDevice - to create Pipes and other special .inodes
2669 Also note POSIX open flags
2670 2) Close - to return the last write time to do cache across close
2672 3) FindFirst return unique inode number - what about resume key, two
2673 forms short (matches readdir) and full (enough info to cache inodes)
2676 And under consideration:
2677 5) FindClose2 (return nanosecond timestamp ??)
2678 6) Use nanosecond timestamps throughout all time fields if
2679 corresponding attribute flag is set
2680 7) sendfile - handle based copy
2682 what about fixing 64 bit alignment
2684 There are also various legacy SMB/CIFS requests used as is
2686 From existing Lanman and NTLM dialects:
2687 --------------------------------------
2689 SESSION_SETUP_ANDX (BB which?)
2690 TREE_CONNECT_ANDX (BB which wct?)
2691 TREE_DISCONNECT (BB add volume timestamp on response)
2693 DELETE (note delete open file behavior)
2697 LOCKING_AND_X (note posix lock semantics)
2698 RENAME (note rename across dirs and open file rename posix behaviors)
2699 NT_RENAME (for hardlinks) Is this good enough for all features?
2701 TRANSACTION2 (18 cases)
2702 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2703 (BB verify that never need to set allocation size)
2704 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2707 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2708 setting/getting OS/2 EAs - FUTURE (BB can this handle
2709 setting Linux xattrs perfectly) - OPTIONAL
2710 dnotify - FUTURE, OPTIONAL
2711 quota - FUTURE, OPTIONAL
2713 Note that various requests implemented for NT interop such as
2714 NT_TRANSACT (IOCTL) QueryReparseInfo
2715 are unneeded to servers compliant with the CIFS POSIX extensions
2717 From CIFS Unix Extensions:

2720 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
2721 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
2722 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) BB check for missing
2724 Actually a need QUERY_FILE_UNIX_INFO
2726 BB what about a) blksize/blkbits/blocks
2732 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
2733 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
2734 T2_QFS_INFO QueryDevice/AttributeInfo - OPTIONAL
