Andrey Konovalov 2e577732e8 kasan, fortify: properly rename memintrinsics ... After commit 69d4c0d321 ("entry, kasan, x86: Disallow overriding mem*() functions") and the follow-up fixes, with CONFIG_FORTIFY_SOURCE enabled, even though the compiler instruments meminstrinsics by generating calls to __asan/__hwasan_ prefixed functions, FORTIFY_SOURCE still uses uninstrumented memset/memmove/memcpy as the underlying functions. As a result, KASAN cannot detect bad accesses in memset/memmove/memcpy. This also makes KASAN tests corrupt kernel memory and cause crashes. To fix this, use __asan_/__hwasan_memset/memmove/memcpy as the underlying functions whenever appropriate. Do this only for the instrumented code (as indicated by __SANITIZE_ADDRESS__).
