Existing AI workloads? A few annotations and I can now transparently change their behaviour, swap out models in their API calls and more. (Thanks to #eBPF)

Re-found the virtual machine manager project for Kubernetes from last year, this example has BeOS inside a kubernetes cluster ssh-ing out to the control plane to manage itself 😂. No CNI needed either thanks to eBPF.

Regardless of what the AI client is (GO, Python etc...) we can now ensure we jump in to the "existing" data path and manipulate any of the data in either direction 😀

Using eBPF 🐝 and some proxy magic 🪄 to change the model on the fly transparently to the AI workload. We can see the first responses from llama and subsequent ones from gemma (more emojis).

Two pods with their traffic being proxied (thx eBPF 🐝) through a gateway, one using kTLS and the other user-land TLS. 🔐

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.
