Modified Files: src/sys/netinet6 [netbsd-8]: ip6_forward.c Log Message: Pull up following revision(s) (requested by maxv in ticket #671): sys/netinet6/ip6_forward.c: revision 1.91 Fix two pretty bad mistakes. If ipsec6_check_policy fails m is not freed, and a 'goto out' is missing after ipsec6_process_packet.
