We need to disable UBSAN for 'vdso-ilp32' like commit ab2a69eee74d ("Fix compile problem when CONFIG_KASAN and CONFIG_UBSAN were on") `.data' referenced in section `.text' of arch/arm64/kernel/vdso-ilp32/gettimeofday-ilp32.o: defined in discarded section `.data' of arch/arm64/kernel/vdso-ilp32/gettimeofday-ilp32.o `.data' referenced in section `.text' of arch/arm64/kernel/vdso-ilp32/gettimeofday-ilp32.o: defined in discarded section `.data' of arch/arm64/kernel/vdso-ilp32/gettimeofday-ilp32.o `.data' referenced in section `.text' of arch/arm64/kernel/vdso-ilp32/gettimeofday-ilp32.o: defined in discarded section `.data' of arch/arm64/kernel/vdso-ilp32/gettimeofday-ilp32.o `.data' referenced in section `.text' of arch/arm64/kernel/vdso-ilp32/gettimeofday-ilp32.o: defined in discarded section `.data' of arch/arm64/kernel/vdso-ilp32/gettimeofday-ilp32.o `.data' referenced in section `.text' of arch/arm64/kernel/vdso-ilp32/gettimeofday-ilp32.o: defined in discarded section `.data' of arch/arm64/kernel/vdso-ilp32/gettimeofday-ilp32.o `.data' referenced in section `.text' of arch/arm64/kernel/vdso-ilp32/gettimeofday-ilp32.o: defined in discarded section `.data' of arch/arm64/kernel/vdso-ilp32/gettimeofday-ilp32.o `.data' referenced in section `.text' of arch/arm64/kernel/vdso-ilp32/gettimeofday-ilp32.o: defined in discarded section `.data' of arch/arm64/kernel/vdso-ilp32/gettimeofday-ilp32.o `.data' referenced in section `.text' of arch/arm64/kernel/vdso-ilp32/gettimeofday-ilp32.o: defined in discarded section `.data' of arch/arm64/kernel/vdso-ilp32/gettimeofday-ilp32.o `.data' referenced in section `.text' of arch/arm64/kernel/vdso-ilp32/gettimeofday-ilp32.o: defined in discarded section `.data' of arch/arm64/kernel/vdso-ilp32/gettimeofday-ilp32.o Signed-off-by: Wei Li <liwei391@huawei.com> Signed-off-by: Xiongfeng Wang <wangxiongfeng2@huawei.com> Reviewed-by: Hanjun Guo <guohanjun@huawei.com> Signed-off-by: Yang Yingliang <yangyingliang@huawei.com> Signed-off-by: Xiongfeng Wang <wangxiongfeng2@huawei.com> Reviewed-by: Cheng Jian <cj.chengjian@huawei.com> --- arch/arm64/kernel/vdso-ilp32/Makefile | 3 +++ 1 file changed, 3 insertions(+) diff --git a/arch/arm64/kernel/vdso-ilp32/Makefile b/arch/arm64/kernel/vdso-ilp32/Makefile index 9a5bbe313769..088ba0a7237d 100644 --- a/arch/arm64/kernel/vdso-ilp32/Makefile +++ b/arch/arm64/kernel/vdso-ilp32/Makefile @@ -55,6 +55,9 @@ endif # Disable gcov profiling for VDSO code GCOV_PROFILE := n +KASAN_SANITIZE := n +UBSAN_SANITIZE := n +KCOV_INSTRUMENT := n obj-y += vdso-ilp32.o extra-y += vdso-ilp32.lds -- 2.20.1
