Created attachment 2110828 [details] Attaching my patch The change is in bpf_tracing header file where sp doesn't exist for powerpc arch.
Michel, any update on this upstream?
hey @yaakov, I created a PR against libbpf, but that time it was already merged in latest build. https://github.com/libbpf/libbpf/pull/931. Remaining things I think Michel will know.
Looks like libbpf used by retsnoop needs to be rebased to a newer commit, in the meantime once the Python mini-mass-rebuild currently hogging capacity is over I'll try and apply this patch
