[tor-relays] Re: DDoS solution for Tor nodes - nftables variant implemented



I wrote it in a confusing way:

Block crazy packets in chain 'ingress' before conntrack & defrag
and like this in line 172, in mangle (prerouting)

# enum for the IPv4 protocol.

enum nf_ip_hook_priorities {
	NF_IP_PRI_FIRST = INT_MIN,
	NF_IP_PRI_RAW_BEFORE_DEFRAG = -450,
	NF_IP_PRI_CONNTRACK_DEFRAG = -400,
	NF_IP_PRI_RAW = -300,
	NF_IP_PRI_SELINUX_FIRST = -225,
	NF_IP_PRI_CONNTRACK = -200,
	NF_IP_PRI_MANGLE = -150,
	NF_IP_PRI_NAT_DST = -100,
	NF_IP_PRI_FILTER = 0,
	NF_IP_PRI_SECURITY = 50,
	NF_IP_PRI_NAT_SRC = 100,
	NF_IP_PRI_SELINUX_LAST = 225,
	NF_IP_PRI_CONNTRACK_HELPER = 300,
	NF_IP_PRI_CONNTRACK_CONFIRM = INT_MAX,
	NF_IP_PRI_LAST = INT_MAX,
};
