From 20c349f68ca108d8b20363efbf5fa698e8446009 Mon Sep 17 00:00:00 2001 From: Matthias Schiffer Date: Sun, 10 Dec 2017 18:04:53 +0100 Subject: [PATCH] busybox: add missing TARGET_CPPFLAGS and TARGET_LDFLAGS Unconditionally pass TARGET_CPPFLAGS (not passed at all before) and TARGET_LDFLAGS (passed only in certain non-default configuration before the Makefile streamlining). Without these flags, hardening options (PKG_FORTIFY_SOURCE and PKG_RELRO) were not actually applied to busybox. The addition of these flags increases the size of the stripped busybox binary by about 6KB (~4KB with fortify headers, ~2KB with "-znow -zrelro") with the default hardening options PKG_FORTIFY_SOURCE_1 and PKG_RELRO_FULL.
