From 964a7cf02a85761c0eb130151ab5b8173994c818 Mon Sep 17 00:00:00 2001 From: jsing Date: Sun, 29 Jan 2023 15:33:43 +0000 Subject: [PATCH] Set BN_FLG_CONSTTIME on benchmark inputs. The public APIs still change behaviour based on BN_FLG_CONSTTIME - set it to avoid benchmark noise. --- regress/lib/libcrypto/bn/bn_mul_div.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/regress/lib/libcrypto/bn/bn_mul_div.c b/regress/lib/libcrypto/bn/bn_mul_div.c index 28f8f756469..77805b9a802 100644 --- a/regress/lib/libcrypto/bn/bn_mul_div.c +++ b/regress/lib/libcrypto/bn/bn_mul_div.c @@ -1,4 +1,4 @@ -/* $OpenBSD: bn_mul_div.c,v 1.3 2023/01/29 15:26:55 jsing Exp $ */ +/* $OpenBSD: bn_mul_div.c,v 1.4 2023/01/29 15:33:43 jsing Exp $ */ /* * Copyright (c) 2023 Joel Sing * @@ -358,6 +358,9 @@ benchmark_run(const struct benchmark *bm, int seconds) if ((q = BN_CTX_get(bn_ctx)) == NULL) errx(1, "BN_CTX_get"); + BN_set_flags(a, BN_FLG_CONSTTIME); + BN_set_flags(b, BN_FLG_CONSTTIME); + if (!bm->setup(a, bm->a_bits, b, bm->b_bits, r, q)) errx(1, "benchmark setup failed"); -- 2.20.1
