From: Guo Ren <guoren@xxxxxxxxxxxxxxxxx> Let riscv enable randomizes the stack, heap and binary images of ELF binaries. Seems it's ok at all after qemu & chip test and there is no founded side effect. So just simply select ARCH_HAS_ELF_RANDOMIZE :) Signed-off-by: Guo Ren <guoren@xxxxxxxxxxxxxxxxx> Cc: Palmer Dabbelt <palmerdabbelt@xxxxxxxxxx> Cc: Paul Walmsley <paul.walmsley@xxxxxxxxxx> Cc: Zong Li <zong.li@xxxxxxxxxx> Cc: Greentime Hu <green.hu@xxxxxxxxx> --- arch/riscv/Kconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/riscv/Kconfig b/arch/riscv/Kconfig index 91bfc6c..eed6647 100644 --- a/arch/riscv/Kconfig +++ b/arch/riscv/Kconfig @@ -20,6 +20,7 @@ config RISCV select ARCH_HAS_GIGANTIC_PAGE select ARCH_HAS_MMIOWB select ARCH_HAS_PTE_SPECIAL + select ARCH_HAS_ELF_RANDOMIZE select ARCH_HAS_SET_DIRECT_MAP select ARCH_HAS_SET_MEMORY select ARCH_HAS_STRICT_KERNEL_RWX if MMU
Actually it is already the case: ARCH_HAS_ELF_RANDOMIZE is already selected by ARCH_WANT_DEFAULT_TOPDOWN_MMAP_LAYOUT.
