2246 And under consideration:
Steve French1982c342005-08-17 12:38:22 -07002247 5) FindClose2 (return nanosecond timestamp ??)
2248 6) Use nanosecond timestamps throughout all time fields if
Linus Torvalds1da177e2005-04-16 15:20:36 -07002249 corresponding attribute flag is set
Steve French1982c342005-08-17 12:38:22 -07002250 7) sendfile - handle based copy
2251 8) Direct i/o
2252 9) Misc fcntls?
Linus Torvalds1da177e2005-04-16 15:20:36 -07002253
2254 what about fixing 64 bit alignment
2255
2256 There are also various legacy SMB/CIFS requests used as is
2257
2258 From existing Lanman and NTLM dialects:
2259 --------------------------------------
2260 NEGOTIATE
2261 SESSION_SETUP_ANDX (BB which?)
2262 TREE_CONNECT_ANDX (BB which wct?)
2263 TREE_DISCONNECT (BB add volume timestamp on response)
2264 LOGOFF_ANDX
2265 DELETE (note delete open file behavior)
2266 DELETE_DIRECTORY
2267 READ_AND_X
2268 WRITE_AND_X
2269 LOCKING_AND_X (note posix lock semantics)
2270 RENAME (note rename across dirs and open file rename posix behaviors)
2271 NT_RENAME (for hardlinks) Is this good enough for all features?
2272 FIND_CLOSE2
2273 TRANSACTION2 (18 cases)
2274 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2275 (BB verify that never need to set allocation size)
2276 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via Unix ext?)
2277
2278 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2279 setting/getting OS/2 EAs - FUTURE (BB can this handle
2280 setting Linux xattrs perfectly) - OPTIONAL
2281 dnotify - FUTURE, OPTIONAL
2282 quota - FUTURE, OPTIONAL
2283
2284 Note that various requests implemented for NT interop such as
2285 NT_TRANSACT (IOCTL) QueryReparseInfo
2286 are unneeded to servers compliant with the CIFS POSIX extensions
2287
2288 From CIFS Unix Extensions:
2289 -------------------------
2290 T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
2291 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
2292 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
2293 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) - BB check for missing inode fields
2294 Actually need QUERY_FILE_UNIX_INFO since has inode num
2295 BB what about a) blksize/blkbits/blocks
2296 b) i_version
2297 c) i_rdev
2298 d) notify mask?
2299 e) generation
2300 f) size_seqcount
2301 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
2302 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
2303 T2_QFS_INFO QueryDevice/AttributeInfo - OPTIONAL
2304
