Bpfvv

bpfvv stands for BPF Verifier Visualizer

https://libbpf.github.io/bpfvv/

BPF Verifier Visualizer is a tool to analyze Linux Kernel BPF verifier logs.

The goal of bpfvv is to help BPF programmers debug verification failures.

The user can load a text file, and the app will attempt to parse it as a verifier log. Successfully parsed lines produce a state which is then visualized in the UI. You can think of this as a primitive debugger UI, except it interprets a log and not a runtime state of a program.

For more information on how to use bpfvv see the HOWTO.md
