2181 For better POSIX semantics from Linux client, (even better
2182 than the existing CIFS Unix Extensions) we need updated PDUs for:
2184 1) PosixCreateX - to set and return the mode, inode#, device info and
2185 perhaps add a CreateDevice - to create Pipes and other special .inodes
2186 Also note POSIX open flags
2187 2) Close - to return the last write time to do cache across close more safely
2188 3) FindFirst return unique inode number - what about resume key, two
2189 forms short (matches readdir) and full (enough info to cache inodes)
2192 And under consideration:
2193 5) FindClose2 (return nanosecond timestamp ??)
2194 6) Use nanosecond timestamps throughout all time fields if
2195 corresponding attribute flag is set
2196 7) sendfile - handle based copy
2200 what about fixing 64 bit alignment
2202 There are also various legacy SMB/CIFS requests used as is
2204 From existing Lanman and NTLM dialects:
2205 --------------------------------------
2207 SESSION_SETUP_ANDX (BB which?)
2208 TREE_CONNECT_ANDX (BB which wct?)
2209 TREE_DISCONNECT (BB add volume timestamp on response)
2211 DELETE (note delete open file behavior)
2215 LOCKING_AND_X (note posix lock semantics)
2216 RENAME (note rename across dirs and open file rename posix behaviors)
2217 NT_RENAME (for hardlinks) Is this good enough for all features?
2219 TRANSACTION2 (18 cases)
2220 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2221 (BB verify that never need to set allocation size)
2222 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via Unix ext?)
2224 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2225 setting/getting OS/2 EAs - FUTURE (BB can this handle
2226 setting Linux xattrs perfectly) - OPTIONAL
2227 dnotify - FUTURE, OPTIONAL
2228 quota - FUTURE, OPTIONAL
2230 Note that various requests implemented for NT interop such as
2231 NT_TRANSACT (IOCTL) QueryReparseInfo
2232 are unneeded to servers compliant with the CIFS POSIX extensions
2234 From CIFS Unix Extensions:
2235 -------------------------
2236 T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
2237 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
2238 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
2239 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) - BB check for missing inode fields
2240 Actually need QUERY_FILE_UNIX_INFO since has inode num
2241 BB what about a) blksize/blkbits/blocks
2247 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
2248 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
2249 T2_QFS_INFO QueryDevice/AttributeInfo - OPTIONAL
