selftests/bpf: Verify calling core kfuncs from BPF_PROG_TYPE_SYCALL

Browse source

Now that we can call some kfuncs from BPF_PROG_TYPE_SYSCALL progs, let's
add some selftests that verify as much. As a bonus, let's also verify
that we can't call the progs from raw tracepoints. Do do this, we add a
new selftest suite called verifier_kfunc_prog_types.
