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!

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.

We finally decided to write out how we use XDP in our network plane for live network migrations and more specifically to process outgoing packets!
This is the first in a series of promised deep dives into how Loophole's live migration tech works!

There's always something new to learn about IP.
New post: SocketAddrV6 is not roundtrip serializable 😱
A journey from an innocent property-based test at Oxide to the depths of the IPv6 specification, with tons of information about the flowinfo (and scope_id) fields. Give it a read!
