* selftests/bpf: Add F_NEEDS_EFFICIENT_UNALIGNED_ACCESS to some testsBjörn Töpel2023-07-051-0/+2
| | | | | | | | | Some verifier tests were missing F_NEEDS_EFFICIENT_UNALIGNED_ACCESS, which made the test fail. Add the flag where needed.

* selftests/bpf: Use __BYTE_ORDER__Ilya Leoshkevich2021-10-251-7/+7
| | | | | | | | | Use the compiler-defined __BYTE_ORDER__ instead of the libc-defined __BYTE_ORDER for consistency. Signed-off-by: Ilya Leoshkevich <iii@linux.ibm.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Link: https://lore.kernel.org/bpf/20211026010831.748682-4-iii@linux.ibm.com

* selftests/bpf: add another gso_segs accessEric Dumazet2019-07-231-0/+11
| | | | | | | | | Use BPF_REG_1 for source and destination of gso_segs read, to exercise "bpf: fix access to skb_shared_info->gso_segs" fix. Signed-off-by: Eric Dumazet <edumazet@google.com> Suggested-by: Stanislav Fomichev <sdf@google.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>

* selftests/bpf: add "any alignment" annotation for some testsBjörn Töpel2019-02-051-0/+1
| | | | | | | | | | RISC-V does, in-general, not have "efficient unaligned access". When testing the RISC-V BPF JIT, some selftests failed in the verification due to misaligned access. Annotate these tests with the F_NEEDS_EFFICIENT_UNALIGNED_ACCESS flag. Signed-off-by: Björn Töpel <bjorn.topel@gmail.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>

* selftests: bpf: break up test_verifierJakub Kicinski2019-01-271-0/+1001
Break up the first 10 kLoC of test verifier test cases out into smaller files. Looks like git line counting gets a little flismy above 16 bit integers, so we need two commits to break up test_verifier.
