From 6910d7d3867a8e65eaecb18a9527ecc9eb2e5edf Mon Sep 17 00:00:00 2001 From: Andrii Nakryiko Date: Thu, 9 Jan 2020 21:17:15 -0800 Subject: selftests/bpf: Ensure bpf_helper_defs.h are taken from selftests dir Reorder includes search path to ensure $(OUTPUT) and $(CURDIR) go before libbpf's directory. Also fix bpf_helpers.h to include bpf_helper_defs.h in such a way as to leverage includes search path. This allows selftests to not use libbpf's local and potentially stale bpf_helper_defs.h. It's important because selftests/bpf's Makefile only re-generates bpf_helper_defs.h in seltests' output directory, not the one in libbpf's directory. Also force regeneration of bpf_helper_defs.h when libbpf.a is updated to reduce staleness.
