Martin KaFai Lau	7a9bb9762d	bpf: Add verifier tests for the bpf_sk_storage ... This patch adds verifier tests for the bpf_sk_storage: 1. ARG_PTR_TO_MAP_VALUE_OR_NULL 2. Map and helper compatibility (e.g. disallow bpf_map_loookup_elem) It also takes this chance to remove the unused struct btf_raw_data and uses the BTF encoding macros from "test_btf.h".

Martin KaFai Lau	b55aa7b04b	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>	2019-03-13 12:04:35 -07:00
Martin KaFai Lau	fb47d1d931	bpf: Add skb->sk, bpf_sk_fullsock and bpf_tcp_sock tests to test_verifer ... This patch tests accessing the skb->sk and the new helpers, bpf_sk_fullsock and bpf_tcp_sock. The errstr of some existing "reference tracking" tests is changed with s/bpf_sock/sock/ and s/socket/sock/ where "sock" is from the verifier's reg_type_str[].
