* selftests: Use consistent include paths for libbpfToke Høiland-Jørgensen2020-01-201-1/+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.

* tools/bpf: Add self tests for bpf_send_signal_thread()Yonghong Song2020-01-151-29/+22
| | | | | | | | | | | | | | | | | | | | | | | The test_progs send_signal() is amended to test bpf_send_signal_thread() as well. $ ./test_progs -n 40 #40/1 send_signal_tracepoint:OK #40/2 send_signal_perf:OK #40/3 send_signal_nmi:OK #40/4 send_signal_tracepoint_thread:OK #40/5 send_signal_perf_thread:OK #40/6 send_signal_nmi_thread:OK #40 send_signal:OK Summary: 1/6 PASSED, 0 SKIPPED, 0 FAILED Also took this opportunity to rewrite the send_signal test using skeleton framework and array mmap to make code simpler and more readable.
