2229 For better POSIX semantics from Linux client, (even better
2230 than the existing CIFS Unix Extensions) we need updated PDUs for:
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)
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
2248 what about fixing 64 bit alignment
2250 There are also various legacy SMB/CIFS requests used as is
2252 From existing Lanman and NTLM dialects:
2253 --------------------------------------
2255 SESSION_SETUP_ANDX (BB which?)
2256 TREE_CONNECT_ANDX (BB which wct?)
2257 TREE_DISCONNECT (BB add volume timestamp on response)
2259 DELETE (note delete open file behavior)
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?
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?)
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
2275 dnotify - FUTURE, OPTIONAL
2276 quota - FUTURE, OPTIONAL
2278 Note that various requests implemented for NT interop such as
2279 NT_TRANSACT (IOCTL) QueryReparseInfo
2280 are unneeded to servers compliant with the CIFS POSIX extensions
2282 From CIFS Unix Extensions:
2283 -------------------------
2284 T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
2285 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
2286 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
2287 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) - BB check for missing inode fields
2288 Actually need QUERY_FILE_UNIX_INFO since has inode num
2289 BB what about a) blksize/blkbits/blocks
2295 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
2296 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
2297 T2_QFS_INFO QueryDevice/AttributeInfo - OPTIONAL
