From 832e41bfdbdf5783141191a5d97a33fa90c8d253 Mon Sep 17 00:00:00 2001 From: Quentin Monnet Date: Mon, 2 Dec 2019 21:06:39 +0800 Subject: [PATCH] selftests/bpf: fix return value comparison for tests in test_libbpf.sh [ Upstream commit c5fa5d602221362f8341ecd9e32d83194abf5bd9 ] The return value for each test in test_libbpf.sh is compared with if (( $? == 0 )) ; then ... This works well with bash, but not with dash, that /bin/sh is aliased to on some systems (such as Ubuntu). Let's replace this comparison by something that works on both shells.
