Martin KaFai Lau e710bcc6d9 bpf: selftest: Ensure the return value of bpf_skc_to helpers must be checked ... This patch tests: int bpf_cls(struct __sk_buff *skb) { /* REG_6: sk * REG_7: tp * REG_8: req_sk */ sk = skb->sk; if (!sk) return 0; tp = bpf_skc_to_tcp_sock(sk); req_sk = bpf_skc_to_tcp_request_sock(sk); if (!req_sk) return 0; /* !tp has not been tested, so verifier should reject. */ return *(__u8 *)tp; } Signed-off-by: Martin KaFai Lau <kafai@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Link: https://lore.kernel.org/bpf/20201019194219.1051314-1-kafai@fb.com		2020-10-19 15:57:42 -07:00
