Make egress traffic look like ingress allowed Loophole Labs leverage XDP to 12x the throughput of iptables, and all without kernel patches 📈
eBPF is freedom to rethink how the kernel works.

Using XDP for Egress Traffic
XDP only works for ingress. We found a loophole that lets it work for egress. Here's how we did the impossible.

An eBPF Loophole: Using XDP for Egress Traffic
XDP is Linux's fastest packet processor but only handles incoming traffic. We found a loophole in how the kernel determines packet direction to make it work for outgoing traffic too!

Just finished the John Candy documentary. He was pretty much in movies of my time so it hit pretty hard. I’d recommend it.

Spent a good 50 mins queuing for the Star Wars ride at Disney, Oscar (who is 5) repeatedly referred to the “lightswords” for the duration and refused to be corrected. Pretty surprised we survived the queue.
