From 95cec14b0308085c028c4d4fb3d09fad3902b4c3 Mon Sep 17 00:00:00 2001 From: Hao Luo <haoluo@google.com> Date: Thu, 3 Sep 2020 13:05:28 -0700 Subject: [PATCH] selftests/bpf: Fix check in global_data_init. The returned value of bpf_object__open_file() should be checked with libbpf_get_error() rather than NULL. This fix prevents test_progs from crash when test_global_data.o is not present.
