selftests/bpf: Store BPF object files with .bpf.o extension

2022-09-02T13:55:37Z

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.

selftests/bpf: Use libbpf 1.0 API mode instead of RLIMIT_MEMLOCK

2022-04-11T03:17:16Z

We have switched to memcg-based memory accouting and thus the rlimit is not needed any more. LIBBPF_STRICT_AUTO_RLIMIT_MEMLOCK was introduced in libbpf for backward compatibility, so we can use it instead now. After this change, the header tools/testing/selftests/bpf/bpf_rlimit.h can be removed. This patch also removes the useless header sys/resource.h from many files in tools/testing/selftests/bpf/.

selftests/bpf: Clean up array_size.cocci warnings

2022-03-15T16:03:10Z

Clean up the array_size.cocci warnings under tools/testing/selftests/bpf/: Use `ARRAY_SIZE(arr)` instead of forms like `sizeof(arr)/sizeof(arr[0])`. tools/testing/selftests/bpf/test_cgroup_storage.c uses ARRAY_SIZE() defined in tools/include/linux/kernel.h (sys/sysinfo.h -> linux/kernel.h), while others use ARRAY_SIZE() in bpf_util.h.

selftests/bpf: Remove all the uses of deprecated bpf_prog_load_xattr()

2021-12-02T23:23:40Z

Migrate all the selftests that were still using bpf_prog_load_xattr(). Few are converted to skeleton, others will use bpf_object__open_file() API. Signed-off-by: Andrii Nakryiko Signed-off-by: Alexei Starovoitov Link: https://lore.kernel.org/bpf/20211201232824.3166325-7-andrii@kernel.org

selftests/bpf: Convert legacy prog load APIs to bpf_prog_load()

2021-11-07T16:34:23Z

Convert all the uses of legacy low-level BPF program loading APIs (mostly bpf_load_program_xattr(), but also some bpf_verify_program()) to bpf_prog_load() uses.

bpf, selftests: Use single cgroup helpers for both test_sockmap/progs

2020-08-02T03:20:59Z

Nearly every user of cgroup helpers does the same sequence of API calls. So push these into a single helper cgroup_setup_and_join. The cases that do a bit of extra logic are test_progs which currently uses an env variable to decide if it needs to setup the cgroup environment or can use an existingi environment. And then tests that are doing cgroup tests themselves. We skip these cases for now.
