https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D244002 --- Comment #24 from commit-hook@freebsd.org --- A commit references this bug: Author: hselasky Date: Mon Feb 24 09:58:58 UTC 2020 New revision: 358274 URL: https://svnweb.freebsd.org/changeset/base/358274 Log: MFC r358013: Fix kernel panic while trying to read multicast stream. When VIMAGE is enabled make sure the "m_pkthdr.rcvif" pointer is set for all mbufs being input by the IGMP/MLD6 code. Else there will be a NULL-pointer dereference in the netisr code when trying to set the VNET based on the incoming mbuf. Add an assert to catch this when queueing mbufs on a netisr to make debugging of similar cases easier. Found by: Vladislav V.
