LT		 2331 For better POSIX semantics from Linux client, (even better
2332 than the existing CIFS Unix Extensions) we need updated PDUs for:
50c2f753 2333
1da177e4
LT		 2334 1) PosixCreateX - to set and return the mode, inode#, device info and
2335 perhaps add a CreateDevice - to create Pipes and other special .inodes
2336 Also note POSIX open flags
50c2f753 2337 2) Close - to return the last write time to do cache across close
87f440e7 2338 more safely
50c2f753 2339 3) FindFirst return unique inode number - what about resume key, two
1982c344
SF		 2340 forms short (matches readdir) and full (enough info to cache inodes)
2341 4) Mkdir - set mode
50c2f753
SF		 2342
2343 And under consideration:
1982c344 2344 5) FindClose2 (return nanosecond timestamp ??)
50c2f753 2345 6) Use nanosecond timestamps throughout all time fields if
1da177e4 2346 corresponding attribute flag is set
1982c344
SF		 2347 7) sendfile - handle based copy
2348 8) Direct i/o
2349 9) Misc fcntls?
50c2f753 2350
1da177e4 2351 what about fixing 64 bit alignment
50c2f753 2352
1da177e4 2353 There are also various legacy SMB/CIFS requests used as is
50c2f753 2354
1da177e4
LT		 2355 From existing Lanman and NTLM dialects:
2356 --------------------------------------
2357 NEGOTIATE
2358 SESSION_SETUP_ANDX (BB which?)
2359 TREE_CONNECT_ANDX (BB which wct?)
2360 TREE_DISCONNECT (BB add volume timestamp on response)
2361 LOGOFF_ANDX
2362 DELETE (note delete open file behavior)
2363 DELETE_DIRECTORY
2364 READ_AND_X
2365 WRITE_AND_X
2366 LOCKING_AND_X (note posix lock semantics)
2367 RENAME (note rename across dirs and open file rename posix behaviors)
2368 NT_RENAME (for hardlinks) Is this good enough for all features?
2369 FIND_CLOSE2
2370 TRANSACTION2 (18 cases)
2371 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2372 (BB verify that never need to set allocation size)
87f440e7
SF		 2373 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2374 Unix ext?)
50c2f753 2375
1da177e4
LT		 2376 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2377 setting/getting OS/2 EAs - FUTURE (BB can this handle
2378 setting Linux xattrs perfectly) - OPTIONAL
2379 dnotify - FUTURE, OPTIONAL
2380 quota - FUTURE, OPTIONAL
50c2f753
SF		 2381
2382 Note that various requests implemented for NT interop such as
1da177e4
LT		 2383 NT_TRANSACT (IOCTL) QueryReparseInfo
2384 are unneeded to servers compliant with the CIFS POSIX extensions
50c2f753 2385
1da177e4
LT		 2386 From CIFS Unix Extensions:
2387 -------------------------
2388 T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
2389 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
2390 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
50c2f753
SF		 2391 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) BB check for missing
2392 inode fields
2393 Actually a need QUERY_FILE_UNIX_INFO
2394 since has inode num
2395 BB what about a) blksize/blkbits/blocks
87f440e7
SF		 2396 b) i_version
2397 c) i_rdev
2398 d) notify mask?
