selftests/bpf: test map percpu stats 2023-07-06T19:42:25+00:00 Anton Protopopov aspsk@isovalent.com 2023-07-06T13:39:32+00:00 6c1b8cb6a70ad4b357fbc92fc9c5d6bc67593351 Add a new map test, map_percpu_stats.c, which is checking the correctness of map's percpu elements counters. For supported maps the test upserts a number of elements, checks the correctness of the counters, then deletes all the elements and checks again that the counters sum drops down to zero. The following map types are tested: * BPF_MAP_TYPE_HASH, BPF_F_NO_PREALLOC * BPF_MAP_TYPE_PERCPU_HASH, BPF_F_NO_PREALLOC * BPF_MAP_TYPE_HASH, * BPF_MAP_TYPE_PERCPU_HASH, * BPF_MAP_TYPE_LRU_HASH * BPF_MAP_TYPE_LRU_PERCPU_HASH * BPF_MAP_TYPE_LRU_HASH, BPF_F_NO_COMMON_LRU * BPF_MAP_TYPE_LRU_PERCPU_HASH, BPF_F_NO_COMMON_LRU * BPF_MAP_TYPE_HASH_OF_MAPS Signed-off-by: Anton Protopopov <aspsk@isovalent.com> Acked-by: Hou Tao <houtao1@huawei.com> Link: https://lore.kernel.org/r/20230706133932.45883-6-aspsk@isovalent.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>
