eBPF Summit

eBPF Summit is back for 2025 and this year, it’s a Hackathon! 🐝 Instead of the usual lineup of talks and keynotes, we want to see you get creative! Whether you’re crafting your very first eBPF program, showing off an idea for a new eBPF-based utility, writing a blog post to help others get started, or adding new features for projects like Cilium, Tetragon, and Hubble, this is your opportunity to contribute in your own way. The submission period opens next Monday, October 13, and will be open through November 30.

eBPF Foundation has a new website to keep up with the pace of what we are doing including: 100k to academic research Launch of inaugural Community & Advocacy Fellowship Program SOWs to improve eBPF selftests and hardware architecture support Sponsoring LPC to bring developers together 6 case studies 2 white papers under development It's going to be a busy end of the year 🐝

You have to love the title Creating a Linux “Yogurt-phone” — with netkit and a grain of eBPF because it turns kernel tinkering into a science fair project. Instead of two yogurt cups tied with a string, we have network namespaces and netkit interfaces, with eBPF acting as the string. It walks through building a "string" between two namespaces using only netkit pairs and a minimal eBPF program. Along the way, Jean-Tiare Le Bigot reverse engineers kernel behavior and give us a peak into kernel code. It also reminds me what makes the eBPF ecosystem fun. You can prototype something and end up uncovering details of kernel internals and the next generation of container networking. https://lnkd.in/dU4E226J

Join Liz Rice and Dylan Reimerink for the next eCHO Livestream on 3 October for a look at the clang-free runtime config for Cilium and eBPF. Liz and Dylan will highlight the 'clang-free' Cilium Epic to remove hashtag # ifdefs from the code and replace them with runtime configuration mechanism that doesn't require reconfiguration. This is an important step towards shipping a distro-less container image. They will dive into the benefits, including a more natural developer experience, avoiding high CPU consumption from datapath recompilations, and more! eBPF & Cilium Office Hours Friday, 3 October - 9am ET / 3pm CET Livestream: https://lnkd.in/ey6r2iYa Hear more from Liz: https://lnkd.in/es4ez5dW #eBPF #cloudnative #cilium #eCHO

 SIGCOMM hosted the third edition of the eBPF workshop and Paul Chaignon pulled together all the papers and presentations in to one place. From profiling XDP to scheduling BPF programs, lots of interesting research topics this year!

What if your pub/sub broker could handle more messages with less latency—just by using #eBPF? 🐝 In the latest eBPFChirp, we look at how eBPF accelerates pub/sub by handling parts of the messaging path in the kernel.

Loads of fun chatting with Eden Naftali and Amitai Cohen on the Crying Out Cloud podcast! We covered a lot of ground in half an hour: "cloud confessions" about everything from my favourite bike ride, through AI in creative arts, to live coding, to the covers for my O'Reilly books... and discussing #eBPF, the #CNCF, and much more!
