selftest/bpf: Add map_in_maps with BPF_MAP_TYPE_PERF_EVENT_ARRAY values Check that bpf_object__load() successfully creates map_in_maps with BPF_MAP_TYPE_PERF_EVENT_ARRAY values. These changes cover fix in the previous patch "libbpf: Apply map_set_def_max_entries() for inner_maps on creation". A command line output is: - w/o fix $ sudo ./test_maps libbpf: map 'mim_array_pe': failed to create inner map: -22 libbpf: map 'mim_array_pe': failed to create: Invalid argument(-22) libbpf: failed to load object './test_map_in_map.bpf.o' Failed to load test prog - with fix $ sudo ./test_maps ... test_maps: OK, 0 SKIPPED Fixes: 646f02ffdd49 ("libbpf: Add BTF-defined map-in-map support") Signed-off-by: Andrey Grafin <conquistador@yandex-team.ru> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Acked-by: Yonghong Song <yonghong.song@linux.dev> Acked-by: Hou Tao <houtao1@huawei.com> Link: https://lore.kernel.org/bpf/20240117130619.9403-2-conquistador@yandex-team.ru Signed-off-by: Alexei Starovoitov <ast@kernel.org>

selftests/bpf: Remove SEC("version") from test progs Since commit 6c4fc209fcf9d ("bpf: remove useless version check for prog load") these "version" sections, which result in bpf_attr.kern_version being set, have been unnecessary. Remove them so that it's obvious to folks using selftests as a guide that "modern" BPF progs don't need this section.

selftests/bpf: Normalize XDP section names in selftests Convert almost all SEC("xdp_blah") uses to strict SEC("xdp") to comply with strict libbpf 1.0 logic of exact section name match for XDP program types. There is only one exception, which is only tested through iproute2 and defines multiple XDP programs within the same BPF object. Given iproute2 still works in non-strict libbpf mode and it doesn't have means to specify XDP programs by its name (not section name/title), leave that single file alone for now until iproute2 gains lookup by function/program name.

selftests: Use consistent include paths for libbpf Fix all selftests to include libbpf header files with the bpf/ prefix, to be consistent with external users of the library. Also ensure that all includes of exported libbpf header files (those that are exported on 'make install' of the library) use bracketed includes instead of quoted. To not break the build, keep the old include path until everything has been changed to the new one; a subsequent patch will remove that.

tools/bpf: selftests: add map lookup to test_map_in_map bpf prog The bpf_map_lookup_elem is added in the bpf program.

selftests: bpf: centre kernel bpf objects under new subdir "progs" At the moment, all kernel bpf objects are listed under BPF_OBJ_FILES. Listing them manually sometimes causing patch conflict when people are adding new testcases simultaneously. It is better to centre all the related source files under a subdir "progs", then auto-generate the object file list.
