Stanislav Fomichev	488a23b89d	selftests/bpf: Move existing common networking parts into network_helpers ... 1. Move pkt_v4 and pkt_v6 into network_helpers and adjust the users. 2. Copy-paste spin_lock_thread into two tests that use it.

Willem de Bruijn	62511ceadf	selftests/bpf: Test new __sk_buff field gso_size ... Analogous to the gso_segs selftests introduced in commit d9ff286a0f ("bpf: allow BPF programs access skb_shared_info->gso_segs field").

Nikita V. Shirokov	6de6c1f840	bpf: Allow to change skb mark in test_run ... allow to pass skb's mark field into bpf_prog_test_run ctx for BPF_PROG_TYPE_SCHED_CLS prog type. that would allow to test bpf programs which are doing decision based on this field Signed-off-by: Nikita V.

Stanislav Fomichev	3daf8e703e	selftests: bpf: add selftest for __sk_buff context in BPF_PROG_TEST_RUN ... Simple test that sets cb to {1,2,3,4,5} and priority to 6, runs bpf program that fails if cb is not what we expect and increments cb[i] and priority. When the test finishes, we check that cb is now {2,3,4,5,6} and priority is 7. We also test the sanity checks: * ctx_in is provided, but ctx_size_in is zero (same for ctx_out/ctx_size_out) * unexpected non-zero fields in __sk_buff return EINVAL Signed-off-by: Stanislav Fomichev <sdf@google.com> Acked-by: Martin KaFai Lau <kafai@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>	2019-04-11 10:21:41 +02:00
