selftests: Use consistent include paths for libbpf

2020-01-21T00:37:45Z

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.

selftests: bpf: standardize to static __always_inline

2019-07-03T13:06:33Z

The progs for bpf selftests use several different notations to force function inlining. Standardize to what most of them use, static __always_inline. Suggested-by: Song Liu Signed-off-by: Jiri Benc Signed-off-by: Daniel Borkmann

selftests/bpf: add few verifier scale tests

2019-04-03T23:27:38Z

Add 3 basic tests that stress verifier scalability. test_verif_scale1.c calls non-inlined jhash() function 90 times on different position in the packet. This test simulates network packet parsing. jhash function is ~140 instructions and main program is ~1200 insns. test_verif_scale2.c force inlines jhash() function 90 times. This program is ~15k instructions long. test_verif_scale3.c calls non-inlined jhash() function 90 times on But this time jhash has to process 32-bytes from the packet instead of 14-bytes in tests 1 and 2. jhash function is ~230 insns and main program is ~1200 insns. $ test_progs -s can be used to see verifier stats.
