    Problem Text
    In the test for addr.len too small, the t_errno is checked for a value of
    TBUFOVFLW, but the returned udata.len is also checked to make sure
    it is equal to zero. It isn't clear from the XTI specifications that
    these values are meaningful when t_rcvudata() returns an error, in fact
    an XTI user should assume that anything returned in udata is meaningless
    in this case, as the manual states that the datagram is discarded.

    Would it be possible to allow the return of udata.len != 0 in this case?

    Note that the failure of the second part of this test case, when opt.len
    is too small, is due to an unrelated problem in our XTI implementation.

    Review Recommendation No Resolution Given
    Review Response
    The udata.len field is explicitly tested to be zero because of the statement
    in the XTI specification associated with the TBUFOVFLW error which says

    "The unit data information to be returned in unitdata will be
    discarded".

    This seems to be a case where the XTI specification makes a requirement on
    the implementation which is not being met by the system under test.

    It is recommended that this request is rejected.
