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.

2019-11-24	bpf, testing: Add various tail call test cases	Daniel Borkmann	1	-0/+31
	Add several BPF kselftest cases for tail calls which test the various patch directions, and that multiple locations are patched in same and different programs. # ./test_progs -n 45 #45/1 tailcall_1:OK #45/2 tailcall_2:OK #45/3 tailcall_3:OK #45/4 tailcall_4:OK #45/5 tailcall_5:OK #45 tailcalls:OK Summary: 1/5 PASSED, 0 SKIPPED, 0 FAILED I've also verified the JITed dump after each of the rewrite cases that it matches expectations. Also regular test_verifier suite passes fine which contains further tail call tests: # ./test_verifier [...] Summary: 1563 PASSED, 0 SKIPPED, 0 FAILED Checked under JIT, interpreter and JIT + hardening.
