1814 For better POSIX semantics from Linux client, (even better
1815 than the existing CIFS Unix Extensions) we need updated PDUs for:
1817 1) PosixCreateX - to set and return the mode, inode#, device info and
1818 perhaps add a CreateDevice - to create Pipes and other special .inodes
1819 Also note POSIX open flags
1820 2) Close - to return the last write time to do cache across close more safely
1821 3) PosixQFSInfo - to return statfs info
1822 4) FindFirst return unique inode number - what about resume key, two forms short (matches readdir) and full (enough info to cache inodes)
1825 And under consideration:
1826 6) FindClose2 (return nanosecond timestamp ??)
1827 7) Use nanosecond timestamps throughout all time fields if
1828 corresponding attribute flag is set
1829 8) sendfile - handle based copy
1831 10) "POSIX ACL" support
1834 what about fixing 64 bit alignment
1836 There are also various legacy SMB/CIFS requests used as is
1838 From existing Lanman and NTLM dialects:
1839 --------------------------------------
1841 SESSION_SETUP_ANDX (BB which?)
1842 TREE_CONNECT_ANDX (BB which wct?)
1843 TREE_DISCONNECT (BB add volume timestamp on response)
1845 DELETE (note delete open file behavior)
1849 LOCKING_AND_X (note posix lock semantics)
1850 RENAME (note rename across dirs and open file rename posix behaviors)
1851 NT_RENAME (for hardlinks) Is this good enough for all features?
1853 TRANSACTION2 (18 cases)
1854 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
1855 (BB verify that never need to set allocation size)
1856 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via Unix ext?)
1858 COPY (note support for copy across directories) - FUTURE, OPTIONAL
1859 setting/getting OS/2 EAs - FUTURE (BB can this handle
1860 setting Linux xattrs perfectly) - OPTIONAL
1861 dnotify - FUTURE, OPTIONAL
1862 quota - FUTURE, OPTIONAL
1864 Note that various requests implemented for NT interop such as
1865 NT_TRANSACT (IOCTL) QueryReparseInfo
1866 are unneeded to servers compliant with the CIFS POSIX extensions
1868 From CIFS Unix Extensions:
1869 -------------------------
1870 T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
1871 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
1872 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
1873 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) - BB check for missing inode fields
1874 Actually need QUERY_FILE_UNIX_INFO since has inode num
1875 BB what about a) blksize/blkbits/blocks
1881 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
1882 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
1883 T2_QFS_INFO QueryDevice/AttributeInfo - OPTIONAL
