Oops, I can read. :) Doing a build now... > And how do I run the test myself directly? I found: https://docs.kernel.org/bpf/bpf_devel_QA.html But it doesn't seem to cover a bunch of stuff (no way to prebuild the tests, no info on building the test modules). This seems to be needed: make O=regression-bug -C tools/testing/selftests/bpf/test_kmods But then the booted kernel doesn't load it (missing signatures?) Anyway, I'll keep digging... -- Kees Cook
