2024-09-04	selftests: bpf: Replace sizeof(arr)/sizeof(arr[0]) with ARRAY_SIZE	Feng Yang	1	-1/+2
	The ARRAY_SIZE macro is more compact and more formal in linux source. Signed-off-by: Feng Yang <yangfeng@kylinos.cn> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Link: https://lore.kernel.org/bpf/20240903072559.292607-1-yangfeng59949@163.com
2023-06-19	bpf: Centralize permissions checks for all BPF map types	Andrii Nakryiko	1	-1/+5
	This allows to do more centralized decisions later on, and generally makes it very explicit which maps are privileged and which are not (e.g., LRU_HASH and LRU_PERCPU_HASH, which are privileged HASH variants, as opposed to unprivileged HASH and HASH_PERCPU; now this is explicit and easy to verify).

2023-02-17	selftests/bpf: Use bpf_{btf,link,map,prog}_get_info_by_fd()	Ilya Leoshkevich	1	-4/+4
	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
2022-05-23	selftests/bpf: Fix spelling mistake: "unpriviliged" -> "unprivileged"	Colin Ian King	1	-2/+2
	There are spelling mistakes in ASSERT messages. Fix these. Signed-off-by: Colin Ian King <colin.i.king@gmail.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Link: https://lore.kernel.org/bpf/20220523115604.49942-1-colin.i.king@gmail.com
2022-05-21	selftests/bpf: add tests verifying unprivileged bpf behaviour	Alan Maguire	1	-0/+312
	tests load/attach bpf prog with maps, perfbuf and ringbuf, pinning them. Then effective caps are dropped and we verify we can - pick up the pin - create ringbuf/perfbuf - get ringbuf/perfbuf events, carry out map update, lookup and delete - create a link Negative testing also ensures - BPF prog load fails - BPF map create fails - get fd by id fails - get next id fails - query fails - BTF load fails Signed-off-by: Alan Maguire <alan.maguire@oracle.com> Acked-by: Yonghong Song <yhs@fb.com> Link: https://lore.kernel.org/r/1652970334-30510-3-git-send-email-alan.maguire@oracle.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>
