Hi.
With 4.4.1 I've got BUG_ON() triggered in net/netfilter/nf_nat_core.c:395, nf_nat_setup_info(), today on my home router.
Here is full trace got via netconsole: [1]
I perform LAN NATting using nftables like this:
=== table ip nat { chain prerouting { type nat hook prerouting priority -150; } chain postrouting { type nat hook postrouting priority -150; oifname enp2s0 ip saddr 172.17.28.0/24 counter snat 1.2.3.4 oifname enp2s0 ip saddr 172.17.29.0/24 counter snat 1.2.3.4 oifname enp2s0 ip saddr 172.17.31.0/24 counter snat 1.2.3.4 oifname enp2s0 ip saddr 172.17.35.0/24 counter snat 1.2.3.4 oifname enp2s0 ip saddr 172.17.37.0/24 counter snat 1.2.3.4 oifname tun0 ip saddr 172.17.28.0/24 counter masquerade oifname tun0 ip saddr 172.17.29.0/24 counter masquerade oifname tinc0 ip saddr 172.17.28.0/24 counter masquerade oifname tinc0 ip saddr 172.17.29.0/24 counter masquerade } } ===
Traffic filtering is done via nftables as well.
Ideas? What could I do to debug the issue better?
