2020-01-20	selftests: Use consistent include paths for libbpf	Toke Høiland-Jørgensen
	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.

2019-02-27	tools/bpf: selftests: add map lookup to test_map_in_map bpf prog	Yonghong Song
	The bpf_map_lookup_elem is added in the bpf program. Without previous patch, the test change will trigger the following error: $ ./test_maps ... ; value_p = bpf_map_lookup_elem(map, &key); 20: (bf) r1 = r7 21: (bf) r2 = r8 22: (85) call bpf_map_lookup_elem#1 ; if (!value_p \|\| value_p != 123) 23: (15) if r0 == 0x0 goto pc+16 R0=map_value(id=2,off=0,ks=4,vs=4,imm=0) R6=inv1 R7=map_ptr(id=0,off=0,ks=4,vs=4,imm=0) R8=fp-8,call_-1 R10=fp0,call_-1 fp-8=mmmmmmmm ; if (!value_p \|\| value_p != 123) 24: (61) r1 = (u32 )(r0 +0) R0=map_value(id=2,off=0,ks=4,vs=4,imm=0) R6=inv1 R7=map_ptr(id=0,off=0,ks=4,vs=4,imm=0) R8=fp-8,call_-1 R10=fp0,call_-1 fp-8=mmmmmmmm bpf_spin_lock cannot be accessed directly by load/store With the kernel fix in the previous commit, the error goes away.

2019-02-11	selftests: bpf: centre kernel bpf objects under new subdir "progs"	Jiong Wang
	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.
