1716 For better POSIX semantics from Linux client, (even better
1717 than the existing CIFS Unix Extensions) we need updated PDUs for:
1719 1) PosixCreateX - to set and return the mode, inode#, device info and
1720 perhaps add a CreateDevice - to create Pipes and other special .inodes
1721 Also note POSIX open flags
1722 2) Close - to return the last write time to do cache across close more safely
1723 3) PosixQFSInfo - to return statfs info
1724 4) FindFirst return unique inode number - what about resume key, two forms short (matches readdir) and full (enough info to cache inodes)
1727 And under consideration:
1728 6) FindClose2 (return nanosecond timestamp ??)
1729 7) Use nanosecond timestamps throughout all time fields if
1730 corresponding attribute flag is set
1731 8) sendfile - handle based copy
1733 10) "POSIX ACL" support
1736 what about fixing 64 bit alignment
1738 There are also various legacy SMB/CIFS requests used as is
1740 From existing Lanman and NTLM dialects:
1741 --------------------------------------
1743 SESSION_SETUP_ANDX (BB which?)
1744 TREE_CONNECT_ANDX (BB which wct?)
1745 TREE_DISCONNECT (BB add volume timestamp on response)
1747 DELETE (note delete open file behavior)
1751 LOCKING_AND_X (note posix lock semantics)
1752 RENAME (note rename across dirs and open file rename posix behaviors)
1753 NT_RENAME (for hardlinks) Is this good enough for all features?
1755 TRANSACTION2 (18 cases)
1756 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
1757 (BB verify that never need to set allocation size)
1758 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via Unix ext?)
1760 COPY (note support for copy across directories) - FUTURE, OPTIONAL
1761 setting/getting OS/2 EAs - FUTURE (BB can this handle
1762 setting Linux xattrs perfectly) - OPTIONAL
1763 dnotify - FUTURE, OPTIONAL
1764 quota - FUTURE, OPTIONAL
1766 Note that various requests implemented for NT interop such as
1767 NT_TRANSACT (IOCTL) QueryReparseInfo
1768 are unneeded to servers compliant with the CIFS POSIX extensions
1770 From CIFS Unix Extensions:
1771 -------------------------
1772 T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
1773 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
1774 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
1775 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) - BB check for missing inode fields
1776 Actually need QUERY_FILE_UNIX_INFO since has inode num
1777 BB what about a) blksize/blkbits/blocks
1783 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
1784 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
1785 T2_QFS_INFO QueryDevice/AttributeInfo - OPTIONAL
