2229         For better POSIX semantics from Linux client, (even better
2230         than the existing CIFS Unix Extensions) we need updated PDUs for:
2231
2232         1) PosixCreateX - to set and return the mode, inode#, device info and
2233         perhaps add a CreateDevice - to create Pipes and other special .inodes
2234         Also note POSIX open flags
2235         2) Close - to return the last write time to do cache across close more safely
2236         3) FindFirst return unique inode number - what about resume key, two
2237         forms short (matches readdir) and full (enough info to cache inodes)
2238         4) Mkdir - set mode
2239
2240         And under consideration:
2241         5) FindClose2 (return nanosecond timestamp ??)
2242         6) Use nanosecond timestamps throughout all time fields if
2243            corresponding attribute flag is set
2244         7) sendfile - handle based copy
2245         8) Direct i/o
2246         9) Misc fcntls?
2247
2248         what about fixing 64 bit alignment
2249
2250         There are also various legacy SMB/CIFS requests used as is

2254         NEGOTIATE
2255         SESSION_SETUP_ANDX (BB which?)
2256         TREE_CONNECT_ANDX (BB which wct?)
2257         TREE_DISCONNECT (BB add volume timestamp on response)
2258         LOGOFF_ANDX
2259         DELETE (note delete open file behavior)
2260         DELETE_DIRECTORY
2261         READ_AND_X
2262         WRITE_AND_X
2263         LOCKING_AND_X (note posix lock semantics)
2264         RENAME (note rename across dirs and open file rename posix behaviors)
2265         NT_RENAME (for hardlinks) Is this good enough for all features?
2266         FIND_CLOSE2
2267         TRANSACTION2 (18 cases)
2268                 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2269                 (BB verify that never need to set allocation size)
2270                 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via Unix ext?)
2271
2272         COPY (note support for copy across directories) - FUTURE, OPTIONAL
2273         setting/getting OS/2 EAs - FUTURE (BB can this handle
2274         setting Linux xattrs perfectly)         - OPTIONAL
