Ebpf

eBPF is a technology allowing you to dynamically program the kernel using a virtual machine approach. Several development frameworks exist, with the top choice for Rust developers being Aya. Because of the deep integration between eBPF and the Linux kernel, it can be challenging to create a local development environment that works across different development machines. To date, I’ve taken to developing eBPF programs on EC2 instances using the AWS Cloud9 development environment. This works, but comes with its own issues and won’t be for everyone. ...

eBPF is a relatively new extension of the Linux kernel that can run sandboxed programs in a privileged context. It is used to safely and efficiently extend the capabilities of the kernel at runtime without requiring changes to kernel source code or the loading of kernel modules. Because of eBPFs tight integration with the networking stack at the kernel level, it is seeing adoption in networking applications. This includes Kubernetes networking through eBPF implementations of the Kubnernetes networking stack like Cilium. ...
