From d3294cb1e06d70a689924792c2acb897eac7d781 Mon Sep 17 00:00:00 2001 From: Geliang Tang Date: Thu, 19 May 2022 16:30:11 -0700 Subject: [PATCH] selftests/bpf: Enable CONFIG_IKCONFIG_PROC in config CONFIG_IKCONFIG_PROC is required by BPF selftests, otherwise we get errors like this: libbpf: failed to open system Kconfig libbpf: failed to load object 'kprobe_multi' libbpf: failed to load BPF skeleton 'kprobe_multi': -22 It's because /proc/config.gz is opened in bpf_object__read_kconfig_file() in tools/lib/bpf/libbpf.c: file = gzopen("/proc/config.gz", "r"); So this patch enables CONFIG_IKCONFIG and CONFIG_IKCONFIG_PROC in tools/testing/selftests/bpf/config.
