This makes it more difficult -to exploit security vulnerabilities that require knowledge of fixed -hardware addresses. - -The firmware generates a 8 byte random number during bootup and stores -it in the device tree under chosen/kaslr-seed. This number is used -to randomize the address mapping. - -This change enables this feature in the build configuration for ARM64. - -Signed-off-by: Michael Zoran <mzoran@crowfest.net> ---- - arch/arm64/configs/bcmrpi3_defconfig | 1 + - 1 file changed, 1 insertion(+) - ---- a/arch/arm64/configs/bcmrpi3_defconfig -+++ b/arch/arm64/configs/bcmrpi3_defconfig -@@ -53,6 +53,7 @@ CONFIG_ARMV8_DEPRECATED=y - CONFIG_SWP_EMULATION=y - CONFIG_CP15_BARRIER_EMULATION=y - CONFIG_SETEND_EMULATION=y -+CONFIG_RANDOMIZE_BASE=y - CONFIG_CMDLINE="console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 root=/dev/mmcblk0p2 rootfstype=ext4 rootwait" - CONFIG_BINFMT_MISC=y - CONFIG_COMPAT=y |
