https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D227674 --- Comment #4 from commit-hook@freebsd.org --- A commit references this bug: Author: ae Date: Thu May 3 08:15:32 UTC 2018 New revision: 333206 URL: https://svnweb.freebsd.org/changeset/base/333206 Log: MFC r332886: icmp6_reflect() sends ICMPv6 message with new IPv6 header. So, it is considered as originated by our host packet. And thus rcvif should be NULL, since it is used by ipfw(4) to determine that packet was originat= ed from this host. Some of icmp6_reflect() consumers reuse mbuf and m_pkth= dr without resetting rcvif pointer. To avoid this always reset m_pkthdr.rc= vif pointer to NULL in icmp6_reflect(). Also remove such line and comment describing this from icmp6_error(), since it does not longer matters.
