2020-01-20selftests: Use consistent include paths for libbpfToke Høiland-Jørgensen1-1/+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.

2019-08-06selftests/bpf: add loop test 5Alexei Starovoitov1-0/+32
Add a test with multiple exit conditions. It's not an infinite loop only when the verifier can properly track all math on variable 'i' through all possible ways of executing this loop. barrier()s are needed to disable llvm optimization that combines multiple branches into fewer branches.
