From bf82deff7069599c9f130f5bb0222acd171fd19d Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sun, 2 Aug 2015 07:40:12 +0000 Subject: [PATCH] build: disable kernel stack protector support for i386/x86_64 When stack protector support is disabled in libc (always the case for !musl), gcc assumes that it needs to use __stack_chk_guard for the stack canary. This causes kernel build errors, because the kernel is only set up to handle TLS stack canaries.
