Open Source Summit + Embedded Linux Conference Europe 2026 (Prague) report and presentation notes

Finally I sufficiently edited my notes for a little belated post on the Open Source Summit + Embedded Linux Conference Europe 2026 in Prague. I was quite excited to attend as it was my first conference/summit, and it certainly delivered. Organizationally, it was handled very well, and there were always plenty of presentations, booths, and activities to attend. The schedule was also planned in such a way that coming up to the booths to talk about projects (which ranged from things like Flatcar container Linux to RISC-V automotive projects and many, many more across the entire open source and embedded space) in-between some talks and during breaks was generally feasible, so over the course of the several-day conference you could visit most if not all of them.

Fuzzing TIPC protocol implementation in Linux with Syzkaller

This post describes my first experience fuzzing the Linux kernel with syzkaller, in particular its implementation of a rather obscure protocol, TIPC. It was also a good opportunity to explore the kernel internals in bigger detail. While diving into the specification of the TIPC protocol, I carried out experiments in parallel by bringing up TIPC nodes on a local and a virtual machine to simulate a cluster whose nodes communicate via this protocol.
