2024-06-12	bpf: selftests: Fix bpf_map_sum_elem_count() kfunc prototype	Daniel Xu	1	-1/+1
	The prototype in progs/map_percpu_stats.c is not in line with how the actual kfuncs are defined in kernel/bpf/map_iter.c. This causes compilation errors when kfunc prototypes are generated from BTF. Fix by aligning with actual kfunc definitions.

2023-07-06	selftests/bpf: test map percpu stats	Anton Protopopov	1	-0/+24
	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>
