LT		 2317 For better POSIX semantics from Linux client, (even better
2318 than the existing CIFS Unix Extensions) we need updated PDUs for:
50c2f753 2319
1da177e4
LT		 2320 1) PosixCreateX - to set and return the mode, inode#, device info and
2321 perhaps add a CreateDevice - to create Pipes and other special .inodes
2322 Also note POSIX open flags
50c2f753 2323 2) Close - to return the last write time to do cache across close
87f440e7 2324 more safely
50c2f753 2325 3) FindFirst return unique inode number - what about resume key, two
1982c344
SF		 2326 forms short (matches readdir) and full (enough info to cache inodes)
2327 4) Mkdir - set mode
50c2f753
SF		 2328
2329 And under consideration:
1982c344 2330 5) FindClose2 (return nanosecond timestamp ??)
50c2f753 2331 6) Use nanosecond timestamps throughout all time fields if
1da177e4 2332 corresponding attribute flag is set
1982c344
SF		 2333 7) sendfile - handle based copy
2334 8) Direct i/o
2335 9) Misc fcntls?
50c2f753 2336
1da177e4 2337 what about fixing 64 bit alignment
50c2f753 2338
1da177e4 2339 There are also various legacy SMB/CIFS requests used as is
50c2f753 2340

2342 --------------------------------------
2343 NEGOTIATE
2344 SESSION_SETUP_ANDX (BB which?)
2345 TREE_CONNECT_ANDX (BB which wct?)
2346 TREE_DISCONNECT (BB add volume timestamp on response)
2347 LOGOFF_ANDX
2348 DELETE (note delete open file behavior)
2349 DELETE_DIRECTORY
2350 READ_AND_X
2351 WRITE_AND_X
2352 LOCKING_AND_X (note posix lock semantics)
2353 RENAME (note rename across dirs and open file rename posix behaviors)
2354 NT_RENAME (for hardlinks) Is this good enough for all features?
2355 FIND_CLOSE2
2356 TRANSACTION2 (18 cases)
2357 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2358 (BB verify that never need to set allocation size)
87f440e7
SF		 2359 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2360 Unix ext?)
50c2f753 2361
1da177e4
LT		 2362 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2363 setting/getting OS/2 EAs - FUTURE (BB can this handle
2364 setting Linux xattrs perfectly) - OPTIONAL
2365 dnotify - FUTURE, OPTIONAL
2366 quota - FUTURE, OPTIONAL

SF		 2367
2368 Note that various requests implemented for NT interop such as
1da177e4

50c2f753 2371

2376 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
50c2f753

2378 inode fields
2379 Actually a need QUERY_FILE_UNIX_INFO

2381 BB what about a) blksize/blkbits/blocks
87f440e7
