2023-02-16selftests/bpf: Use bpf_{btf,link,map,prog}_get_info_by_fd()Ilya Leoshkevich1-1/+1
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
2022-09-02selftests/bpf: Store BPF object files with .bpf.o extensionDaniel Müller1-2/+2
BPF object files are, in a way, the final artifact produced as part of the ahead-of-time compilation process. That makes them somewhat special compared to "regular" object files, which are a intermediate build artifacts that can typically be removed safely. As such, it can make sense to name them differently to make it easier to spot this difference at a glance. Among others, libbpf-bootstrap [0] has established the extension .bpf.o for BPF object files. It seems reasonable to follow this example and establish the same denomination for selftest build artifacts. To that end, this change adjusts the corresponding part of the build system and the test programs loading BPF object files to work with .bpf.o files.

2021-11-25selftests/bpf: Migrate selftests to bpf_map_create()Andrii Nakryiko1-2/+2
Conversion is straightforward for most cases. In few cases tests are using mutable map_flags and attribute structs, but bpf_map_create_opts can be used in the similar fashion, so there were no problems. Just lots of repetitive conversions.

2021-07-23libbpf: Add bpf_map__pin_path functionEvgeniy Litvinenko1-0/+9
Add bpf_map__pin_path, so that the inconsistently named bpf_map__get_pin_path can be deprecated later. This is part of the effort towards libbpf v1.0: https://github.com/libbpf/libbpf/issues/307 Also, add a selftest for the new function.
