Basic kernel booting is tested on arm kernel enabled CONFIG_UBSAN_SANITIZE_ALL from Exynos5422 based Odroid-XU3 board. Signed-off-by: Seung-Woo Kim --- Because I tested only with specific soc board, so I am not sure the ubsan is fine for all other cases. So, I send this patch as a RFC. --- arch/arm/Kconfig | 1 + arch/arm/boot/compressed/Makefile | 1 + arch/arm/vdso/Makefile | 1 + 3 files changed, 3 insertions(+) diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig index 90542db..3a9af80 100644 --- a/arch/arm/Kconfig +++ b/arch/arm/Kconfig @@ -7,6 +7,7 @@ config ARM select ARCH_HAS_TICK_BROADCAST if GENERIC_CLOCKEVENTS_BROADCAST select ARCH_HAVE_CUSTOM_GPIO_H select ARCH_HAS_GCOV_PROFILE_ALL + select ARCH_HAS_UBSAN_SANITIZE_ALL select ARCH_MIGHT_HAVE_PC_PARPORT select ARCH_SUPPORTS_ATOMIC_RMW select ARCH_USE_BUILTIN_BSWAP diff --git a/arch/arm/boot/compressed/Makefile b/arch/arm/boot/compressed/Makefile index d50430c..883374f 100644 --- a/arch/arm/boot/compressed/Makefile +++ b/arch/arm/boot/compressed/Makefile @@ -23,6 +23,7 @@ OBJS += hyp-stub.o endif GCOV_PROFILE := n +UBSAN_SANITIZE := n # # Architecture dependencies diff --git a/arch/arm/vdso/Makefile b/arch/arm/vdso/Makefile index 59a8fa7..cb90e59 100644 --- a/arch/arm/vdso/Makefile +++ b/arch/arm/vdso/Makefile @@ -28,6 +28,7 @@ CFLAGS_vgettimeofday.o = -O2 # Disable gcov profiling for VDSO code GCOV_PROFILE := n +UBSAN_SANITIZE := n # Force dependency $(obj)/vdso.o : $(obj)/vdso.so -- 1.7.9.5
