selftests/bpf: Remove the only use of deprecated bpf_object__load_xattr()

2021-12-10T23:29:18Z

Switch from bpf_object__load_xattr() to bpf_object__load() and kernel_log_level in bpf_object_open_opts. Signed-off-by: Andrii Nakryiko Signed-off-by: Alexei Starovoitov Link: https://lore.kernel.org/bpf/20211209193840.1248570-12-andrii@kernel.org

libbpf: Change bpf_program__set_extra_flags to bpf_program__set_flags

2021-11-19T22:21:37Z

bpf_program__set_extra_flags has just been introduced so we can still change it without breaking users. This new interface is a bit more flexible (for example if someone wants to clear a flag).

selftests/bpf: Fix bpf_prog_test_load() logic to pass extra log level

2021-11-12T00:44:26Z

After recent refactoring bpf_prog_test_load(), used across multiple selftests, lost ability to specify extra log_level 1 or 2 (for -vv and -vvv, respectively). Fix that problem by using bpf_object__load_xattr() API that supports extra log_level flags. Also restore BPF_F_TEST_RND_HI32 prog_flags by utilizing new bpf_program__set_extra_flags() API.

selftests/bpf: Merge test_stub.c into testing_helpers.c

2021-11-07T16:34:23Z

Move testing prog and object load wrappers (bpf_prog_test_load and bpf_test_load_program) into testing_helpers.{c,h} and get rid of otherwise useless test_stub.c. Make testing_helpers.c available to non-test_progs binaries as well.

selftests/bpf: Extract parse_num_list into generic testing_helpers.c

2020-05-13T19:19:38Z

Add testing_helpers.c, which will contain generic helpers for test runners and tests needing some common generic functionality, like parsing a set of numbers.
