From 2b58bd384730ac2cd177fd8e4d0bf0aa4a0bf166 Mon Sep 17 00:00:00 2001 From: Chenguang Zhao Date: Fri, 28 Jul 2023 10:30:42 +0800 Subject: [PATCH] LoongArch: BPF: Enable bpf_probe_read{, str}() on LoongArch commit de0e30bee86d0f99c696a1fea34474e556a946ec upstream. Currently nettrace does not work on LoongArch due to missing bpf_probe_read{,str}() support, with the error message: ERROR: failed to load kprobe-based eBPF ERROR: failed to load kprobe-based bpf According to commit 0ebeea8ca8a4d1d ("bpf: Restrict bpf_probe_read{, str}() only to archs where they work"), we only need to select CONFIG_ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE to add said support, because LoongArch does have non-overlapping address ranges for kernel and userspace.
