2603 For better POSIX semantics from Linux client, (even better
2604 than the existing CIFS Unix Extensions) we need updated PDUs for:
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
2611 3) FindFirst return unique inode number - what about resume key, two
2612 forms short (matches readdir) and full (enough info to cache inodes)
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
2621 what about fixing 64 bit alignment
2623 There are also various legacy SMB/CIFS requests used as is
2625 From existing Lanman and NTLM dialects:
2626 --------------------------------------
2628 SESSION_SETUP_ANDX (BB which?)
2629 TREE_CONNECT_ANDX (BB which wct?)
2630 TREE_DISCONNECT (BB add volume timestamp on response)
2632 DELETE (note delete open file behavior)
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?
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
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
2652 Note that various requests implemented for NT interop such as
2653 NT_TRANSACT (IOCTL) QueryReparseInfo
2654 are unneeded to servers compliant with the CIFS POSIX extensions
2656 From CIFS Unix Extensions:
2657 -------------------------
2658 T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
2659 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
2660 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
2661 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) BB check for missing
2663 Actually a need QUERY_FILE_UNIX_INFO
2665 BB what about a) blksize/blkbits/blocks
2671 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
2672 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
2673 T2_QFS_INFO QueryDevice/AttributeInfo - OPTIONAL
