Basic kernel bootup test is passed on arm with CONFIG_UBSAN_SANITIZE_ALL enabled. Signed-off-by: Seung-Woo Kim --- This is resend of the patch I already sent, [1], without RFC tag. [1] https://patchwork.kernel.org/patch/9189533/ I tested kernel build and basic boot up on Exynos5422, Exynos4412 and Exynos3250 SoC boards. At previous time on [1], there were some build error on other systems, but they were caused by driver bug or gcc bug. So I think UBSAN on ARM can be re-considered. --- arch/arm/Kconfig | 1 + arch/arm/boot/compressed/Makefile | 1 + arch/arm/vdso/Makefile | 1 + 3 files changed, 3 insertions(+), 0 deletions(-) diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig index a9c4e48..a80f9b1 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 -- 1.7.4.1
