crypto: x86/sha1 - fix possible crash with CFI enabled
sha1_transform_ssse3(), sha1_transform_avx(), and sha1_ni_transform() (but not sha1_transform_avx2()) are called via indirect function calls. Therefore they need to use SYM_TYPED_FUNC_START instead of SYM_FUNC_START to cause their type hashes to be emitted when the kernel is built with CONFIG_CFI_CLANG=y. Otherwise, the code crashes with a CFI failure (if the compiler didn't happen to optimize out the indirect calls). Fixes: ccace936eec7 ("x86: Add types to indirectly called assembly functions") Acked-by: Peter Zijlstra (Intel) <[email protected]> Reviewed-by: Sami Tolvanen <[email protected]> Signed-off-by: Eric Biggers <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
