From 4dfa6b7a300188db2d97a291f9c1303286a6bcc5 Mon Sep 17 00:00:00 2001 From: Julien Dusser <julien.dusser@free.fr> Date: Tue, 17 Jul 2018 18:29:34 +0200 Subject: [PATCH] build: fix ASLR for LTO packages Fix building packages with LTO when CONFIG_PKG_ASLR_PIE is enabled. Despite comment of PR lto/80838, it seems that GCC needs -fPIC on linker command line, even if all objects are -fPIC. This may change as PR lto/80838 is merged into 8.1 compile-tested: ar71xx, ath79 Fix commits: 6dac92a42e052f89971762173daabb7fd84742ef 8c11133c9de632dca69c8464f911d8e2716effe2 07940acc341ee9bb2887359f193625e48f36207e e7397eef69a20fc630148d0e597523e139d21c0c ef16a394d2b24a363b50b5b4720cb23fe156c9da ef96d1e34a990871c912938c336f51a510b1e32f 47b42137ce1e931ae5871952b1f98438396f5e07 73fc67b61480a3430d31de33478a1c0c2c364b9c 154c0c4006daf41e2cbb6c8b7ad5557f83dfea3e 804c51e1e661819c5a7532e66fb8a12166eef9a9 Signed-off-by: Julien Dusser <julien.dusser@free.fr> --- include/hardening.mk | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/include/hardening.mk b/include/hardening.mk index 42ce1f56b5..60f39428e8 100644 --- a/include/hardening.mk +++ b/include/hardening.mk @@ -19,7 +19,7 @@ endif ifdef CONFIG_PKG_ASLR_PIE ifeq ($(strip $(PKG_ASLR_PIE)),1) TARGET_CFLAGS += $(FPIC) - TARGET_LDFLAGS += -specs=$(INCLUDE_DIR)/hardened-ld-pie.specs + TARGET_LDFLAGS += $(FPIC) -specs=$(INCLUDE_DIR)/hardened-ld-pie.specs endif endif ifdef CONFIG_PKG_CC_STACKPROTECTOR_REGULAR -- 2.30.2
