2593 For better POSIX semantics from Linux client, (even better
2594 than the existing CIFS Unix Extensions) we need updated PDUs for:
2596 1) PosixCreateX - to set and return the mode, inode#, device info and
2597 perhaps add a CreateDevice - to create Pipes and other special .inodes
2598 Also note POSIX open flags
2599 2) Close - to return the last write time to do cache across close
2601 3) FindFirst return unique inode number - what about resume key, two
2602 forms short (matches readdir) and full (enough info to cache inodes)
2605 And under consideration:
2606 5) FindClose2 (return nanosecond timestamp ??)
2607 6) Use nanosecond timestamps throughout all time fields if
2608 corresponding attribute flag is set
2609 7) sendfile - handle based copy
2611 what about fixing 64 bit alignment
2613 There are also various legacy SMB/CIFS requests used as is
2615 From existing Lanman and NTLM dialects:
2616 --------------------------------------
2618 SESSION_SETUP_ANDX (BB which?)
2619 TREE_CONNECT_ANDX (BB which wct?)
2620 TREE_DISCONNECT (BB add volume timestamp on response)
2622 DELETE (note delete open file behavior)
2626 LOCKING_AND_X (note posix lock semantics)
2627 RENAME (note rename across dirs and open file rename posix behaviors)
2628 NT_RENAME (for hardlinks) Is this good enough for all features?
2630 TRANSACTION2 (18 cases)
2631 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2632 (BB verify that never need to set allocation size)
2633 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2636 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2637 setting/getting OS/2 EAs - FUTURE (BB can this handle
2638 setting Linux xattrs perfectly) - OPTIONAL
2639 dnotify - FUTURE, OPTIONAL
2640 quota - FUTURE, OPTIONAL
2642 Note that various requests implemented for NT interop such as
2643 NT_TRANSACT (IOCTL) QueryReparseInfo
2644 are unneeded to servers compliant with the CIFS POSIX extensions
2646 From CIFS Unix Extensions:
2647 -------------------------

2649 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
2650 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
2651 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) BB check for missing

2655 BB what about a) blksize/blkbits/blocks
2661 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
2662 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
