Like to hack Linux, @barebox@fosstodon.org, in-betweens and beyond.
If you are at #39c3 and are curious about how kernel and firmware use #OpenFirmware device tree to discover hardware and how @barebox@fosstodon.org (and other bootloaders) use it when booting Linux, come by tomorrow at 13:00 at the open source firmware assembly in Hall 3 Foyer!
If you can't make it and you don't find me near the #barebox demo at the assembly, shoot me a message, I am happy to meet up and chat about all things #embedded #linux, barebox and liberating boot!
This year has seen a number of people putting quite some effort into strengthening the @barebox@fosstodon.org bootloader's security posture .
At @LinuxSecSummit@social.kernel.org in Amsterdam, I had the opportunity to present some of the work: security-focused documentation, fuzzing, hardening and a new framework for runtime access control.
The (correct!) slides are online now: https://static.sched.com/hosted_files/lsseu2025/94/hardening-the-barebox-bootloader.pdf
