bpf: respect size hint to BPF_PROG_TEST_RUN if present Use data_size_out as a size hint when copying test output to user space. ENOSPC is returned if the output buffer is too small. Callers which so far did not set data_size_out are not affected. Signed-off-by: Lorenz Bauer <lmb@cloudflare.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
