AbortWithErrors.seq - Termination of an association by receiving ABORT with more error causes
To check that receiving ABORT message with more error cause can terminate an association.
./AbortWithErrors.seq [-tooloption ...] -pkt ./AbortWithErrors.def -tooloption : v6eval tool option See Also: ../common/STD_PKT_COMMON.def ../common/SCTP_COMMON.def
Association is established between endpoint A and B. Arrange the data in endpoint A such that an ABORT message is sent to endpoint B containing more error causes in it.
Endpoint A Endpoint B ULP (ESTABLISHED) (ESTABLISHED)
ABORT --------------> Association is removed With more error causes Communication Lost --------->
TEST DESCRIPTION:
1. Attempt to terminate an association between endpoint A and endpoint B by sending ABORT message with more error causes. 2. ABORT message is sent either with Peer's V-tag or Local V-tag with T-bit set to 0. 3. Check A: No Acknowledgement is sent for the ABORT message and association is removed. 4. Check B: ULP are reported of the association closure.
None
RFC 4960
9.1. Abort of an Association
When an endpoint decides to abort an existing association, it MUST send an ABORT chunk to its peer endpoint. The sender MUST fill in the peer's Verification Tag in the outbound packet and MUST NOT bundle any DATA chunk with the ABORT. If the association is aborted on request of the upper layer, a User-Initiated Abort error cause (see Section 3.3.10.12) SHOULD be present in the ABORT chunk.
An endpoint MUST NOT respond to any received packet that contains an ABORT chunk (also see Section 8.4).
An endpoint receiving an ABORT MUST apply the special Verification Tag check rules described in Section 8.5.1.
After checking the Verification Tag, the receiving endpoint MUST remove the association from its record and SHOULD report the termination to its upper layer. If a User-Initiated Abort error cause is present in the ABORT chunk, the Upper Layer Abort Reason SHOULD be made available to the upper layer.
