2273 For better POSIX semantics from Linux client, (even better
2274 than the existing CIFS Unix Extensions) we need updated PDUs for:
2275
2276 1) PosixCreateX - to set and return the mode, inode#, device info and
2277 perhaps add a CreateDevice - to create Pipes and other special .inodes
2278 Also note POSIX open flags
87f440e7
SF		 2279 2) Close - to return the last write time to do cache across close
2280 more safely
1982c344
SF		 2281 3) FindFirst return unique inode number - what about resume key, two
2282 forms short (matches readdir) and full (enough info to cache inodes)
2283 4) Mkdir - set mode
1da177e4
LT		 2284
2285 And under consideration:
1982c344
SF		 2286 5) FindClose2 (return nanosecond timestamp ??)
2287 6) Use nanosecond timestamps throughout all time fields if
1da177e4 2288 corresponding attribute flag is set
1982c344
SF		 2289 7) sendfile - handle based copy
2290 8) Direct i/o
2291 9) Misc fcntls?
1da177e4
LT		 2292
2293 what about fixing 64 bit alignment
2294
2295 There are also various legacy SMB/CIFS requests used as is
2296
2297 From existing Lanman and NTLM dialects:
2298 --------------------------------------
2299 NEGOTIATE
2300 SESSION_SETUP_ANDX (BB which?)
2301 TREE_CONNECT_ANDX (BB which wct?)
2302 TREE_DISCONNECT (BB add volume timestamp on response)
2303 LOGOFF_ANDX
2304 DELETE (note delete open file behavior)
2305 DELETE_DIRECTORY
2306 READ_AND_X
2307 WRITE_AND_X
2308 LOCKING_AND_X (note posix lock semantics)
2309 RENAME (note rename across dirs and open file rename posix behaviors)
2310 NT_RENAME (for hardlinks) Is this good enough for all features?
2311 FIND_CLOSE2
2312 TRANSACTION2 (18 cases)
2313 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2314 (BB verify that never need to set allocation size)
87f440e7
SF		 2315 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2316 Unix ext?)
1da177e4
LT		 2317
2318 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2319 setting/getting OS/2 EAs - FUTURE (BB can this handle
2320 setting Linux xattrs perfectly) - OPTIONAL
2321 dnotify - FUTURE, OPTIONAL
2322 quota - FUTURE, OPTIONAL
2323
2324 Note that various requests implemented for NT interop such as
2325 NT_TRANSACT (IOCTL) QueryReparseInfo
2326 are unneeded to servers compliant with the CIFS POSIX extensions
2327
2328 From CIFS Unix Extensions:
2329 -------------------------
2330 T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
2331 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
2332 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
2333 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) - BB check for missing inode fields
2334 Actually need QUERY_FILE_UNIX_INFO since has inode num
2335 BB what about a) blksize/blkbits/blocks
87f440e7
SF		 2336 b) i_version
2337 c) i_rdev
2338 d) notify mask?
2339 e) generation
2340 f) size_seqcount
1da177e4 2341 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
87f440e7 2342 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
