Next week at the fourth eBPF workshop, I will present our paper on netkit we wrote with Daniel.

The SOSP’26 conference has published its list of accepted papers.

I recently had to reinstall my setup to contribute to Linux on a new laptop, and as usual, ran into a few issues with the BPF selftests.

This article is part of a series of notes that Mahé Tardy and I wrote to prepare a presentation introducing the BPF verifier state pruning for Linux Plumbers 2025 in Tokyo.

At SIGCOMM’25, I was asked on two occasions how to test verifier changes on Cilium’s BPF programs.

Last week, the SIGCOMM conference hosted the third edition of the eBPF workshop in Coimbra.

When I started reading on BPF there weren’t many academic papers to describe how it worked, how it didn’t, or how it is used.

Cilium has a fairly large codebase, with many different features, implemented in two very different languages1, and covered by an extensive CI.

This post focuses on the XFRM building blocks Cilium uses to provide its IPsec support.

Last year, the first workshop entirely dedicated to eBPF was hosted by the SIGCOMM conference.

In 2021, Microsoft open sourced their eBPF-for-Windows project.
