2021-10-07	selftests/bpf: Remove SEC("version") from test progs	Dave Marchevsky	1	-1/+0
	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.

2021-07-27	bpf: Increase supported cgroup storage value size	Stanislav Fomichev	1	-4/+4
	Current max cgroup storage value size is 4k (PAGE_SIZE). The other local storages accept up to 64k (BPF_LOCAL_STORAGE_MAX_VALUE_SIZE). Let's align max cgroup value size with the other storages. For percpu, the max is 32k (PCPU_MIN_UNIT_SIZE) because percpu allocator is not happy about larger values. netcnt test is extended to exercise those maximum values (non-percpu max size is close to, but not real max). v4: * remove inner union (Andrii Nakryiko) * keep net_cnt on the stack (Andrii Nakryiko) v3: * refine SIZEOF_BPF_LOCAL_STORAGE_ELEM comment (Yonghong Song) * anonymous struct in percpu_net_cnt & net_cnt (Yonghong Song) * reorder free (Yonghong Song) v2: * cap max_value_size instead of BUILD_BUG_ON (Martin KaFai Lau) Signed-off-by: Stanislav Fomichev <sdf@google.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Acked-by: Martin KaFai Lau <kafai@fb.com> Link: https://lore.kernel.org/bpf/20210727222335.4029096-1-sdf@google.com
2020-01-20	selftests: Use consistent include paths for libbpf	Toke Høiland-Jørgensen	1	-1/+1
	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.

2019-07-05	selftests/bpf: convert selftests using BTF-defined maps to new syntax	Andrii Nakryiko	1	-12/+8
	Convert all the existing selftests that are already using BTF-defined maps to use new syntax (with no static data initialization).

2019-02-11	selftests: bpf: centre kernel bpf objects under new subdir "progs"	Jiong Wang	1	-0/+77
	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.
