NAME

  InvalidParamInInit.seq - INIT chunk is received with invalid parameter length


PURPOSE

  To check that if INIT chunk is received with invalid parameter length, the
  endpoint should send ABORT message with a Protocol Violation error cause.


SYNOPSIS

  ./InvalidParamInInit.seq [-tooloption ...] -pkt ./InvalidParamInInit.def
    -tooloption : v6eval tool option
  See Also: ../common/STD_PKT_COMMON.def
            ../common/SCTP_COMMON.def


PRE-TEST CONDITION

  Association is not established between endpoint A and B. Arrange
  data in endpoint A such that it sends INIT message to endpoint B
  with invalid parameter length.


TEST PROCEDURE

  Endpoint A                           Endpoint B                ULP
  (CLOSED)                             (CLOSED)
  INIT          ----------------->
  (with Invalid Parameter Length)
                <-----------------      ABORT
                                        (Protocol Violation)
  TEST DESCRIPTION:
  1. Attempt to initiate an association from endpoint A to B. Send INIT 
     message with invalid parameter length.
     Record the message sequence using a signal emulator.
  2. Check A: INIT message is discarded and no other actions are taken. 
  3. Check B: Was the message sequence as above.


NOTE

  None

  RFC 4960
  3.3.10.13.  Protocol Violation (13)
    Cause of error
    --------------
    This error cause MAY be included in ABORT chunks that are sent
    because an SCTP endpoint detects a protocol violation of the peer
    that is not covered by the error causes described in Section 3.3.10.1
    to Section 3.3.10.12.  An implementation MAY provide additional
    information specifying what kind of protocol violation has been
    detected.
