From 28e5428d5df083c6015be5abc88959ee2e662eb6 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Lutz=20J=C3=A4nicke?= Date: Tue, 9 Jan 2001 10:58:36 +0000 Subject: [PATCH] Don't cheat: when only getting several bytes from each source, n is incremented correctly, but RAND_add(..,n) counts the increasing n several times. Only RAND_add(..,n) once entropy collection is finished. --- crypto/rand/rand_unix.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/crypto/rand/rand_unix.c b/crypto/rand/rand_unix.c index c4aae38f1..658d35f81 100644 --- a/crypto/rand/rand_unix.c +++ b/crypto/rand/rand_unix.c @@ -183,10 +183,13 @@ int RAND_poll(void) && t.tv_usec != 0 && n < ENTROPY_NEEDED); close(fd); - RAND_add(tmpbuf,sizeof tmpbuf,n); - memset(tmpbuf,0,n); } } + if (n > 0) + { + RAND_add(tmpbuf,sizeof tmpbuf,n); + memset(tmpbuf,0,n); + } #endif /* put in some default random data, we need more than just this */
