bpf: Test ref release issue in bpf_tcp_sock and bpf_sk_fullsock Adding verifier tests to ensure the ptr returned from bpf_tcp_sock() and bpf_sk_fullsock() cannot be accessed after bpf_sk_release() is called. A few of the tests are derived from a reproducer test by Lorenz Bauer. Signed-off-by: Martin KaFai Lau <kafai@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
