Syzkaller has been fuzzing Linux patchsets since August! It already caught more than 100 bugs before they were merged. At #LinuxPlumbers, Aleksandr Nogikh shared some stats and explained why your patchset may not be covered.

@cilium can enforce network policies based on FQDNs using a userspace proxy. At #LinuxPlumbers, @hemanthmalla proposed to move this to the kernel by implementing DNS parsing in #eBPF!

After a great recap of how uprobes work, Jiri Olsa presented recent optimizations and discussed how uprobes could overwrite userspace functions. As usual with Jiri, the slides are minimalist but effective :) #LinuxPlumbers

What a week! 😅 @linuxplumbersconf 2025 is officially over, and what an edition it was.
We went all out this year, covering everything from Linux System Observability and Kernel Testing to Gaming and sched_ext!
Thanks to the organizers and everyone who joined our eight talks. See you at the next #LinuxPlumbers! 👋🐧
#LinuxPlumbers から帰宅
自宅からこんなすぐ近くの所でところでカーネルの話をしてたのはなんとも不思議な感じ
It's been an absolute delight to be here at #LinuxPlumbers, what a great conference!
Of course, one of the big highlights for me was the BoF I ran with Denver about GPL enforcement. Folks had great feedback and enthusiasm and it was great to discuss the #Vizio case and all of our other work! Folks were particularly excited about the #DMCA exceptions we've been able to achieve, which I sometimes forget to talk about.
I'm sad it's the last day!
Rust in Linux is here to stay — and we’re showcasing it at #LinuxPlumbers in Tokyo! Take a break between sessions and race karts on #Tyr, the new Rust DRM driver for Arm Mali GPUs! 🎉 🏁
We’re excited to announce that Linaro is the official T-shirt sponsor for this year’s event! 🚀
Linaro is deeply committed to maintaining the Open Source Community on Arm, with high-performance tooling, open-source leadership and collaborative engineering that drives real long-term impact in a sustainable way.
If you’re at the upcoming Linux Plumbers event, grab yourself a t-shirt and make sure to come chat to one of our Engineers!
