2020-03-04	bpf: Add test ops for BPF_PROG_TYPE_TRACING	KP Singh
	The current fexit and fentry tests rely on a different program to exercise the functions they attach to. Instead of doing this, implement the test operations for tracing which will also be used for BPF_MODIFY_RETURN in a subsequent patch. Also, clean up the fexit test to use the generated skeleton.

2020-01-24	selftests/bpf: Initialize duration variable before using	John Sperbeck
	The 'duration' variable is referenced in the CHECK() macro, and there are some uses of the macro before 'duration' is set. The clang compiler (validly) complains about this. Sample error: .../selftests/bpf/prog_tests/fexit_test.c:23:6: warning: variable 'duration' is uninitialized when used here [-Wuninitialized] if (CHECK(err, "prog_load sched cls", "err %d errno %d\n", err, errno)) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ .../selftests/bpf/test_progs.h:134:25: note: expanded from macro 'CHECK' if (CHECK(err, "prog_load sched cls", "err %d errno %d\n", err, errno)) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ _CHECK(condition, tag, duration, format) ^~~~~~~~ Signed-off-by: John Sperbeck <jsperbeck@google.com> Signed-off-by: Stanislav Fomichev <sdf@google.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Martin KaFai Lau <kafai@fb.com> Link: https://lore.kernel.org/bpf/20200123235144.93610-1-sdf@google.com
