From fb145a59e411e55116f4e2d781103b3958634a89 Mon Sep 17 00:00:00 2001 From: Theo de Raadt Date: Thu, 15 Dec 2022 18:20:40 +0000 Subject: The idiomatic way of coping with signed char vs unsigned char (which did not come from stdio read functions) in the presence of ctype macros, is to always cast to (unsigned char). casting to (int) for a "macro" which is documented to take int, is weird. And sadly wrong, because of the sing extension risk.. same diff from florian --- usr.bin/ssh/misc.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'usr.bin') diff --git a/usr.bin/ssh/misc.c b/usr.bin/ssh/misc.c index 05fa81f1b65..2d6592758fe 100644 --- a/usr.bin/ssh/misc.c +++ b/usr.bin/ssh/misc.c @@ -1,4 +1,4 @@ -/* $OpenBSD: misc.c,v 1.178 2022/11/09 09:01:52 dtucker Exp $ */ +/* $OpenBSD: misc.c,v 1.179 2022/12/15 18:20:39 deraadt Exp $ */ /* * Copyright (c) 2000 Markus Friedl.
