GEN_InvalidChunkLen.seq - Generation of error cause Protocol Violation (Invalid Chunk Length)
To check that if INIT-ACK chunk is received with invalid chunk length
then the endpoint should send ABORT message with cause Protocol
Violation.
./GEN_InvalidChunkLen.seq [-tooloption ...] -pkt ./GEN_InvalidChunkLen.def
-tooloption : v6eval tool option
See Also: ../common/STD_PKT_COMMON.def
../common/SCTP_COMMON.def
Association is not established between endpoint A and B. Arrange data
in endpoint A such that INIT-ACK chunk with invalid chunk length is
sent to endpoint B.

<----------------- ABORT
(Protocol Violation)
TEST DESCRIPTION:
1. Send INIT-ACK chunk from endpoint A to B with invalid chunk
length.
2. Check A: ABORT should be received at endpoint A.
3. Check B: Error cause in ABORT is set to "Protocol Violation".
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.
