# psample test
# - use psample to observe packets
test_psample() {
The merged SCTP test covers only IPv4. The IPv6 extraction path (parse_ipv6hdr walking extension headers, then the proto=132 branch in key_extract) and the v6 side of the SCTP netlink validation have no selftest coverage at all, so a regression there would ship silently. Add test_sctp_connect_v6 mirroring the v4 test: NS/NA forwarding flows stand in for ARP, and ipv6(proto=132),sctp(dst=4443)/sctp(src=4443) flows gate the association in the same three phases (flows installed, flows removed, flows reinstalled). After the association succeeds the test also pushes a known payload across and verifies the listener received it, so a flow-key bug that matches handshake packets but breaks DATA chunks is caught too. Skips when the sctp module is missing, socat lacks SCTP support, or IPv6 is unavailable; an association or DATA failure with the flows installed fails the test.
