Commit 8184d44 ("selftests/bpf: skip verifier tests for unsupported program types") added a check to skip unsupported program types. As bpf_probe_prog_type can change errno, do_single_test should save it before printing a reason why a supported BPF program type failed to load.

Print a message when the returned error is about a program type being not supported or because of permission problems. These messages are expected if the program to test was actually executed. Cc: Krzesimir Nowak <[email protected]> Signed-off-by: Florian Lehner <[email protected]>
