Modified files: sys/netinet : in_pcb.c sys/netinet6 : in6_pcb.c Log message: Relax address availability check for multicast binds. While it makes sense to limit bind(2) of unicast addresses that overlap each other to be all from the same UID (like 0.0.0.0:53 and 127.0.0.1:53) it makes little sense for multicast. Multicast is delivered to all sockets that match so there is no risk of someone stealing traffic from someone else. This should hopefully help with mDNS as reported by robert@ OK deraadt@ bluhm@
