Sometimes I get an infinite flood of 52-byte netlink packets, every time I call recv() on the queue fd. I have ip6tables configured to only queue up certain TCP packets on port 25: ip6tables -I INPUT -i eth0 -p tcp -m tcp --dport 25 \ --tcp-flags FIN,SYN,RST,ACK SYN -j QUEUE ip6tables -nvL during this flood doesn't show the number of packets increasing, so I don't know where the traffic is coming from. If I remove the rule once the flood has started, packets keep coming even though there is no QUEUE rule left! Messages with TCP/IPv4 are 100 bytes, and TCP/IPv6 are 120, so it's a lot smaller than those. Calling nfq_handle_packet() on them returns -1. Where do these packets come from, and how do I get rid of them?
