From 1364e6f1ac1d0aec831b936bc5cfc83211e74495 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Lutz=20J=C3=A4nicke?= Date: Fri, 2 Mar 2007 17:54:31 +0000 Subject: [PATCH] Initialize "buf" to 0 to make valgrind happy :-) Note: the RAND_bytes() manual page says: RAND_bytes() puts num cryptographically strong pseudo-random bytes into buf. It does not talk about using the previous contents of buf so we are working as documented. --- crypto/rand/rand_lib.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/crypto/rand/rand_lib.c b/crypto/rand/rand_lib.c index 513e338985..adfec83b7b 100644 --- a/crypto/rand/rand_lib.c +++ b/crypto/rand/rand_lib.c @@ -154,6 +154,7 @@ void RAND_add(const void *buf, int num, double entropy) int RAND_bytes(unsigned char *buf, int num) { const RAND_METHOD *meth = RAND_get_rand_method(); + memset(buf, 0, num); if (meth && meth->bytes) return meth->bytes(buf,num); return(-1); @@ -162,6 +163,7 @@ int RAND_bytes(unsigned char *buf, int num) int RAND_pseudo_bytes(unsigned char *buf, int num) { const RAND_METHOD *meth = RAND_get_rand_method(); + memset(buf, 0, num); if (meth && meth->pseudorand) return meth->pseudorand(buf,num); return(-1); -- 2.25.1
