bpf, selftests: Use bpf_probe_read_kernel
Since commit 0ebeea8 ("bpf: Restrict bpf_probe_read{, str}() only to archs where they work") 44 verifier tests fail on s390 due to not having bpf_probe_read anymore. Fix by using bpf_probe_read_kernel. Signed-off-by: Ilya Leoshkevich <[email protected]> Signed-off-by: Daniel Borkmann <[email protected]> Link: https://lore.kernel.org/bpf/[email protected]
