2151 For better POSIX semantics from Linux client, (even better
2152 than the existing CIFS Unix Extensions) we need updated PDUs for:
2154 1) PosixCreateX - to set and return the mode, inode#, device info and
2155 perhaps add a CreateDevice - to create Pipes and other special .inodes
2156 Also note POSIX open flags
2157 2) Close - to return the last write time to do cache across close more safely
2158 3) FindFirst return unique inode number - what about resume key, two
2159 forms short (matches readdir) and full (enough info to cache inodes)
2162 And under consideration:
2163 5) FindClose2 (return nanosecond timestamp ??)
2164 6) Use nanosecond timestamps throughout all time fields if
2165 corresponding attribute flag is set
2166 7) sendfile - handle based copy
2170 what about fixing 64 bit alignment
2172 There are also various legacy SMB/CIFS requests used as is
2174 From existing Lanman and NTLM dialects:
2175 --------------------------------------
2177 SESSION_SETUP_ANDX (BB which?)
2178 TREE_CONNECT_ANDX (BB which wct?)
2179 TREE_DISCONNECT (BB add volume timestamp on response)
2181 DELETE (note delete open file behavior)
2185 LOCKING_AND_X (note posix lock semantics)
2186 RENAME (note rename across dirs and open file rename posix behaviors)
2187 NT_RENAME (for hardlinks) Is this good enough for all features?
2189 TRANSACTION2 (18 cases)
2190 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2191 (BB verify that never need to set allocation size)
2192 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via Unix ext?)
2194 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2195 setting/getting OS/2 EAs - FUTURE (BB can this handle
2196 setting Linux xattrs perfectly) - OPTIONAL
2197 dnotify - FUTURE, OPTIONAL
2198 quota - FUTURE, OPTIONAL
2200 Note that various requests implemented for NT interop such as
2201 NT_TRANSACT (IOCTL) QueryReparseInfo
2202 are unneeded to servers compliant with the CIFS POSIX extensions
2204 From CIFS Unix Extensions:
2205 -------------------------
2206 T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
2207 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
2208 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
2209 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) - BB check for missing inode fields
2210 Actually need QUERY_FILE_UNIX_INFO since has inode num
2211 BB what about a) blksize/blkbits/blocks
2217 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
2218 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
2219 T2_QFS_INFO QueryDevice/AttributeInfo - OPTIONAL
