Introduce a configuration option to build a "hardened" OpenWrt with ASLR PIE support. Add new option PKG_ASLR_PIE to enable Address Space Layout Randomization (ASLR) by building Position Independent Executables (PIE). This new option protects against "return-to-text" attacks. Busybox need a special care, link is done with ld, not gcc, leading to unknown flags. Set BUSYBOX_DEFAULT_PIE instead and disable PKG_ASLR_PIE. If other failing packages were found, PKG_ASLR_PIE:=0 should be added to their Makefiles. Original Work by: Yongkui Han <yonhan@cisco.com> Signed-off-by: Julien Dusser <julien.dusser@free.fr> |
