2177 For better POSIX semantics from Linux client, (even better
2178 than the existing CIFS Unix Extensions) we need updated PDUs for:
2180 1) PosixCreateX - to set and return the mode, inode#, device info and
2181 perhaps add a CreateDevice - to create Pipes and other special .inodes
2182 Also note POSIX open flags
2183 2) Close - to return the last write time to do cache across close more safely
2184 3) FindFirst return unique inode number - what about resume key, two
2185 forms short (matches readdir) and full (enough info to cache inodes)
2188 And under consideration:
2189 5) FindClose2 (return nanosecond timestamp ??)
2190 6) Use nanosecond timestamps throughout all time fields if
2191 corresponding attribute flag is set
2192 7) sendfile - handle based copy
2196 what about fixing 64 bit alignment
2198 There are also various legacy SMB/CIFS requests used as is
2200 From existing Lanman and NTLM dialects:
2201 --------------------------------------
2203 SESSION_SETUP_ANDX (BB which?)
2204 TREE_CONNECT_ANDX (BB which wct?)
2205 TREE_DISCONNECT (BB add volume timestamp on response)
2207 DELETE (note delete open file behavior)
2211 LOCKING_AND_X (note posix lock semantics)
2212 RENAME (note rename across dirs and open file rename posix behaviors)
2213 NT_RENAME (for hardlinks) Is this good enough for all features?
2215 TRANSACTION2 (18 cases)
2216 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2217 (BB verify that never need to set allocation size)
2218 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via Unix ext?)
2220 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2221 setting/getting OS/2 EAs - FUTURE (BB can this handle
2222 setting Linux xattrs perfectly) - OPTIONAL
2223 dnotify - FUTURE, OPTIONAL
2224 quota - FUTURE, OPTIONAL
2226 Note that various requests implemented for NT interop such as
2227 NT_TRANSACT (IOCTL) QueryReparseInfo
2228 are unneeded to servers compliant with the CIFS POSIX extensions
2230 From CIFS Unix Extensions:
2231 -------------------------
2232 T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
2233 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
2234 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
2235 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) - BB check for missing inode fields
2236 Actually need QUERY_FILE_UNIX_INFO since has inode num
2237 BB what about a) blksize/blkbits/blocks
2243 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
2244 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
2245 T2_QFS_INFO QueryDevice/AttributeInfo - OPTIONAL
