Currently, under the conditions specified below, IPv6 ingress packet processing can ignore blackhole/reject flag on the prefix. The packet will instead be looped locally till TTL expiration and a single ICMPv6 unreachable message will be send to the source even in case of RTF_BLACKHOLE. The following conditions needs hold to make the scenario happen: * IPv6 forwarding is enabled * Packet is not fast-forwarded * Destination prefix has either RTF_BLACKHOLE or RTF_REJECT flag Fix this behavior by checking for the blackhole/reject flags in ip6_forward().
