Getting Linux based eBPF programs to run with eBPF for Windows
"We have been working to get the Cilium Layer-4 Load Balancer (L4LB) eBPF program running on eBPF for Windows". If you want to dive into the code of how this all works, this is the article for you.
Cracking Kubernetes Network Policy
If you want to understand how network policies are enforced in Kubernetes, this blog shows you how to design a policy enforcer and implement it in less than 100 lines of eBPF code. Examples from Cilium ;)
Increase Kubernetes Network Security with Cilium
This article shows how to tackle authorization with Cilium and push it into the underlying platform instead of the application code.
Code Coverage for eBPF Programs
Bpfcov is a tool to gather source-based coverage info for our eBPF programs running in the Linux kernel
Cilium 1.11.1 Released
This release addresses a range of bugs impacting connectivity, IPAM and egress gateway when particular features are enabled, and they update the underlying base images for the latest library dependencies.
EDB, an eBPF debugger
edb uses a userspace eBPF emulation to run eBPF programs instead of loading them into the kernel, which allows for debugging like other applications. Great to see more tooling coming into the ecosystem.
The Challenge with Deploying eBPF Into the Wild
Write once, run everywhere is the goal we are always trying to achieve. Is it possible with eBPF or do we still have a ways to go? Read the article to dive into the details.

The Ecosystem
Microsoft Brings eBPF to Windows
“One of the reasons Microsoft has been investing in eBPF is because we see the importance of making the data plane itself programmable and controllable by software.” Great to see Microsoft’s continued investment into the ecosystem.
Cilium Service Mesh Feedback
The first results are rolling in. Over 300 people are interested with the most requested features being observability and encryption. Sign up while you can!
EBPF: Observability With Zero Code Instrumentation
One for your boss: “I expect we shall see many more use cases for [eBPF] in the observability space, as well as for security and networking. eBPF may bring us closer than ever before to the vision of automatic instrumentation.” Exactly where Cilium is heading with Hubble too!
