2474 For better POSIX semantics from Linux client, (even better
2475 than the existing CIFS Unix Extensions) we need updated PDUs for:
2476
2477 1) PosixCreateX - to set and return the mode, inode#, device info and
2478 perhaps add a CreateDevice - to create Pipes and other special .inodes
2479 Also note POSIX open flags
2480 2) Close - to return the last write time to do cache across close
2481 more safely
2482 3) FindFirst return unique inode number - what about resume key, two
2483 forms short (matches readdir) and full (enough info to cache inodes)
2484 4) Mkdir - set mode
2485
2486 And under consideration:
2487 5) FindClose2 (return nanosecond timestamp ??)
2488 6) Use nanosecond timestamps throughout all time fields if
2489 corresponding attribute flag is set
2490 7) sendfile - handle based copy
2491 8) Direct i/o
2492 9) Misc fcntls?
2493
2494 what about fixing 64 bit alignment
2495
2496 There are also various legacy SMB/CIFS requests used as is
2497
2498 From existing Lanman and NTLM dialects:
2499 --------------------------------------
2500 NEGOTIATE
2501 SESSION_SETUP_ANDX (BB which?)
2502 TREE_CONNECT_ANDX (BB which wct?)
2503 TREE_DISCONNECT (BB add volume timestamp on response)
2504 LOGOFF_ANDX
2505 DELETE (note delete open file behavior)
2506 DELETE_DIRECTORY
2507 READ_AND_X
2508 WRITE_AND_X
2509 LOCKING_AND_X (note posix lock semantics)
2510 RENAME (note rename across dirs and open file rename posix behaviors)
2511 NT_RENAME (for hardlinks) Is this good enough for all features?
2512 FIND_CLOSE2
2513 TRANSACTION2 (18 cases)
2514 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2515 (BB verify that never need to set allocation size)
2516 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2517 Unix ext?)
2518
2519 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2520 setting/getting OS/2 EAs - FUTURE (BB can this handle
2521 setting Linux xattrs perfectly) - OPTIONAL
2522 dnotify - FUTURE, OPTIONAL
2523 quota - FUTURE, OPTIONAL
2524
2525 Note that various requests implemented for NT interop such as
2526 NT_TRANSACT (IOCTL) QueryReparseInfo
2527 are unneeded to servers compliant with the CIFS POSIX extensions
2528
2529 From CIFS Unix Extensions:
2530 -------------------------

2532 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
2533 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
2534 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) BB check for missing
2535 inode fields
2536 Actually a need QUERY_FILE_UNIX_INFO
2537 since has inode num
2538 BB what about a) blksize/blkbits/blocks
2539 b) i_version
2540 c) i_rdev
2541 d) notify mask?
2542 e) generation
2543 f) size_seqcount
2544 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
2545 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
