Link to v3: https://lore.kernel.org/all/20240812052753.GA478917@quokka/ After a small discussion with Peter, we decided to: - drop the BPF hooks that are problematic (Linus doesn't want "ALLOW_ERROR_INJECTION" to be used as "normal" fmodret bpf hooks) - punt those BPF hooks later once we get the API right - I'll be the one sending that new version, given that it's easier for me ATM For testing the patch, and for convenience, I added a new selftest program that can test this new ioctl. This will also allow us to integrate the (future) BPF hooks and show how this should be used.
