Do you have core dump? Can you show the backtrace from kgdb? A commit references this bug: Author: ae Date: Thu Jun 28 11:39:28 UTC 2018 New revision: 335760 URL: https://svnweb.freebsd.org/changeset/base/335760 Log: Add NULL pointer check. encap_lookup_t method can be invoked by IP encap subsytem even if none of gif/gre/me interfaces are exist. Hash tables are allocated on demand, when first interface is created. So, make NULL pointer check before doing access to hash table. PR: 229378 Changes: head/sys/net/if_me.c head/sys/netinet/in_gif.c head/sys/netinet/ip_gre.c head/sys/netinet6/in6_gif.c head/sys/netinet6/ip6_gre.c I think the problem should be fixed now, thanks! (In reply to Andrey V. Elsukov from comment #3) Confirmed. Thanks! |
Created attachment 194697 [details] crash message After update to the CURRENT yesterday, system crashes with Null pointer assignment as attach below. My internet access is on PPPoE with mpd. Though I don't create gif(4) or gre(4) interfaces, I receive gre packet from several site.
