If you are at #containerdays in #hamburg, make sure to stop by at k2 stage in about an hour to learn about #ebpf 🐝

Performance tracing of #Podman using #eBPF https://www.redhat.com/en/blog/performance-tracing-podman-using-ebpf

I just wrapped up preparation for my keynote at #eBPF Summit 2023, "Building the kernel of tomorrow with eBPF". I'll be exploring ideas around how to build application-specific kernels, the decisions we have around systems API boundaries for eBPF, and some of the ways we've leveraged the technology to build #cloudnative networking solutions in Cilium. Join me on September 13 @ https://ebpf.io/summit-2023

The #eBPF workshop at SIGCOMM will feature two keynotes, by Theophilus A. Benson and my colleague Daniel Borkmann!
Full schedule: https://conferences.sigcomm.org/sigcomm/2023/workshop-ebpf.html.

On Tuesday Aug 29: KBE Insider will export the future of eBPF and Kubernetes with a guest panel of eBPF experts.

Grafana and friends Barcelona Meetup. 19 Septiembre.
Daré una charla en Español sobre el producto basado en #eBPF en el que llevamos trabajando desde que me uní a la compañía en Enero.

"Instrumenta tu aplicación sin añadir una línea de código"

It was really nice to see all the exciting and creative submissions for this year's #eBPF Summit as a member of the Program Committee!

Cannot wait for the conference!

ebpf_exporter v2.2.0 is out 🎉

Highlights include: capability dropping (none can be retained at runtime!), systemd socket activation, percpu maps, syscall decoder, xdp attachment, new benchmarks, new examples (udp drops + kfree_skb), better logging.

Get it now! It's free! Precompiled static binaries are available and you can run examples from the repo.

It's as simple as "sudo ./ebpf_exporter --config.dir=examples --config.names=timers"

And if you understand French, the recording of my #eBPF talk has been published! https://www.youtube.com/watch?v=ZIwvoZId_g4

It's surprisingly hard to figure out how to parse a "struct sk_buff" (aka skb) in #ebpf to extract L4 information like ports. If you wanted an example, I have one for you: https://github.com/cloudflare/ebpf_exporter/pull/235

If you read French, I've uploaded the slides for my #eBPF talk at #Breizhcamp and added references where appropriate: https://pchaigno.github.io/assets/BreizhCamp%202023%20eBPF.pdf

LOL:

```But the mptcpize (LD_PRELOAD technique) command has some limitations […]

- it is not in #BPF, we cannot talk about it at netdev conf. […]```

/me wonders what this kind of argument should be called; "appeal to cool technology" maybe?

I really enjoyed visiting Milan for 3 days with my fiancée this week, then travelling to Birmingham to talk about #eBPF at DevOpsDays!

This Isovalent summer school sounds excellent but sadly I can't attend. Have a looksie. #ebpf #isovalent
