Dmitry Yakunin	21594c4408	bpf: Allow to specify ifindex for skb in bpf_prog_test_run_skb ... Now skb->dev is unconditionally set to the loopback device in current net namespace. But if we want to test bpf program which contains code branch based on ifindex condition (eg filters out localhost packets) it is useful to allow specifying of ifindex from userspace. This patch adds such option through ctx_in (__sk_buff) parameter.

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
