460 * SMB frame definitions (following must be packed structs)

462 *
463 * The Naming convention is the lower case version of the
464 * smb command code name for the struct and this is typedef to the
465 * uppercase version of the same name with the prefix SMB_ removed
466 * for brevity. Although typedefs are not commonly used for
467 * structure definitions in the Linux kernel, their use in the
468 * CIFS standards document, which this code is based on, may
469 * make this one of the cases where typedefs for structures make
470 * sense to improve readability for readers of the standards doc.
471 * Typedefs can always be removed later if they are too distracting
472 * and they are only used for the CIFSs PDUs themselves, not
473 * internal cifs vfs structures

2472 2) Close - to return the last write time to do cache across close
2473 more safely
2474 3) FindFirst return unique inode number - what about resume key, two
2475 forms short (matches readdir) and full (enough info to cache inodes)
2476 4) Mkdir - set mode
2477
2478 And under consideration:
2479 5) FindClose2 (return nanosecond timestamp ??)
2480 6) Use nanosecond timestamps throughout all time fields if
2481 corresponding attribute flag is set
2482 7) sendfile - handle based copy
2483
2484 what about fixing 64 bit alignment
2485
2486 There are also various legacy SMB/CIFS requests used as is
2487
2488 From existing Lanman and NTLM dialects:
2489 --------------------------------------
2490 NEGOTIATE
2491 SESSION_SETUP_ANDX (BB which?)
2492 TREE_CONNECT_ANDX (BB which wct?)
2493 TREE_DISCONNECT (BB add volume timestamp on response)
2494 LOGOFF_ANDX
2495 DELETE (note delete open file behavior)
2496 DELETE_DIRECTORY
2497 READ_AND_X
2498 WRITE_AND_X
2499 LOCKING_AND_X (note posix lock semantics)
2500 RENAME (note rename across dirs and open file rename posix behaviors)
2501 NT_RENAME (for hardlinks) Is this good enough for all features?
2502 FIND_CLOSE2
2503 TRANSACTION2 (18 cases)
2504 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2505 (BB verify that never need to set allocation size)
2506 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2507 Unix ext?)
2508
2509 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2510 setting/getting OS/2 EAs - FUTURE (BB can this handle
2511 setting Linux xattrs perfectly) - OPTIONAL
2512 dnotify - FUTURE, OPTIONAL
2513 quota - FUTURE, OPTIONAL
2514
2515 Note that various requests implemented for NT interop such as
2516 NT_TRANSACT (IOCTL) QueryReparseInfo
2517 are unneeded to servers compliant with the CIFS POSIX extensions
2518
2519 From CIFS Unix Extensions:
2520 -------------------------
2521 T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
2522 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
2523 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
2524 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) BB check for missing
2525 inode fields
2526 Actually a need QUERY_FILE_UNIX_INFO
2527 since has inode num
2528 BB what about a) blksize/blkbits/blocks
2529 b) i_version
2530 c) i_rdev
2531 d) notify mask?
2532 e) generation
2533 f) size_seqcount
2534 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
2535 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
2536 T2_QFS_INFO QueryDevice/AttributeInfo - OPTIONAL
