2023-02-16selftests/bpf: Use bpf_{btf,link,map,prog}_get_info_by_fd()Gravatar Ilya Leoshkevich 1-5/+5
Use the new type-safe wrappers around bpf_obj_get_info_by_fd(). Fix a prog/map mixup in prog_holds_map(). Signed-off-by: Ilya Leoshkevich <iii@linux.ibm.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Link: https://lore.kernel.org/bpf/20230214231221.249277-6-iii@linux.ibm.com
2021-11-07selftests/bpf: Use explicit bpf_test_load_program() helper callsGravatar Andrii Nakryiko 1-2/+2
Remove the second part of prog loading testing helper re-definition: -Dbpf_load_program=bpf_test_load_program This completes the clean up of deprecated libbpf program loading APIs.

2021-05-25selftests/bpf: Turn on libbpf 1.0 mode and fix all IS_ERR checksGravatar Andrii Nakryiko 1-5/+5
Turn ony libbpf 1.0 mode. Fix all the explicit IS_ERR checks that now will be broken because libbpf returns NULL on error (and sets errno). Fix ASSERT_OK_PTR and ASSERT_ERR_PTR to work for both old mode and new modes and use them throughout selftests. This is trivial to do by using libbpf_get_error() API that all libbpf users are supposed to use, instead of IS_ERR checks. A bunch of checks also did explicit -1 comparison for various fd-returning APIs. Such checks are replaced with >= 0 or < 0 cases. There were also few misuses of bpf_object__find_map_by_name() in test_maps. Those are fixed in this patch as well.

2020-06-30selftests: bpf: Pass program and target_fd in flow_dissector_reattachGravatar Lorenz Bauer 1-6/+6
Pass 0 as target_fd when attaching and detaching flow dissector. Additionally, pass the expected program when detaching.

2020-06-30selftests/bpf: Test updating flow_dissector link with same programGravatar Jakub Sitnicki 1-4/+28
This case, while not particularly useful, is worth covering because we expect the operation to succeed as opposed when re-attaching the same program directly with PROG_ATTACH. While at it, update the tests summary that fell out of sync when tests extended to cover links.

2020-06-01selftests/bpf: Add tests for attaching bpf_link to netnsGravatar Jakub Sitnicki 1-37/+551
Extend the existing test case for flow dissector attaching to cover: - link creation, - link updates, - link info querying, - mixing links with direct prog attachment.

2019-10-17selftests/bpf: Restore the netns after flow dissector reattach testGravatar Jakub Sitnicki 1-4/+17
flow_dissector_reattach test changes the netns we run in but does not restore it to the one we started in when finished. This interferes with tests that run after it. Fix it by restoring the netns when done.

2019-10-11selftests/bpf: Check that flow dissector can be re-attachedGravatar Jakub Sitnicki 1-0/+127
Make sure a new flow dissector program can be attached to replace the old one with a single syscall. Also check that attaching the same program twice is prohibited.
