2022-03-15selftests/bpf: Clean up array_size.cocci warningsGuo Zhengkui1-3/+3
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.

2022-02-03selftests/bpf: Migrate from bpf_prog_test_runDelyan Kratunov1-11/+13
bpf_prog_test_run is being deprecated in favor of the OPTS-based bpf_prog_test_run_opts. We end up unable to use CHECK in most cases, so replace usages with ASSERT_* calls.

2022-01-13selftests/bpf: Stop using bpf_map__def() APIChristy Lee1-1/+1
libbpf bpf_map__def() API is being deprecated, replace selftests/bpf's usage with the appropriate getters and setters. Signed-off-by: Christy Lee <christylee@fb.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Link: https://lore.kernel.org/bpf/20220108004218.355761-5-christylee@fb.com
2021-11-07selftests/bpf: Use explicit bpf_prog_test_load() calls everywhereAndrii Nakryiko1-1/+1
-Dbpf_prog_load_deprecated=bpf_prog_test_load trick is both ugly and breaks when deprecation goes into effect due to macro magic. Convert all the uses to explicit bpf_prog_test_load() calls which avoid deprecation errors and makes everything less magical.

2021-10-22selftests/bpf: Switch to ".bss"/".rodata"/".data" lookups for internal mapsAndrii Nakryiko1-2/+9
Utilize libbpf's feature of allowing to lookup internal maps by their ELF section names. No need to guess or calculate the exact truncated prefix taken from the object name.

2020-05-09selftests/bpf: Move existing common networking parts into network_helpersStanislav Fomichev1-0/+1
1. Move pkt_v4 and pkt_v6 into network_helpers and adjust the users. 2. Copy-paste spin_lock_thread into two tests that use it.

2019-08-28selftests/bpf: test_progs: remove global fail/success countsStanislav Fomichev1-15/+5
Now that we have a global per-test/per-environment state, there is no longer need to have global fail/success counters (and there is no need to save/get the diff before/after the test). Introduce CHECK_FAIL macro (suggested by Andrii) and covert existing tests to it. CHECK_FAIL uses new test__fail() to record the failure.
