    Subject[CIFS] still incorrect cifs_reconnect fix?

    while merging commits f01d5e14e764b14b6bf5512678523d009254b209 and
    638b250766272fcaaa0f7ed2776f58f4ac701914 into SLES10, I've noticed that
    there's apparently a bug. The code currently looks like this:

    pdu_length = 4; /* enough to get RFC1001 header */
    length =
    kernel_recvmsg(csocket, &smb_msg,
    &iov, 1, pdu_length, 0 /* BB other flags? */);

    /* ... some irrelevant code left out ... */

    } else if (length < 4) { /* <----- HERE IS THE PROBLEM
    cFYI(1, ("less than four bytes received (%d bytes)",
    pdu_length -= length;
    goto incomplete_rcv;

    I think we should be checking for length < pdu_length, not for length <
    4, because if we read 2 bytes in the first run and 2 bytes in the second
    un, CIFS will still treat the second run as incomplete (and possibly run
    in an infinite loop). Am I missing something obvious?

    Kind regards,
    Petr Tesarik
