Subject: [PATCH 3/9] xtoptions: respect return value in xtables_getportbyname
Date: Sun,  1 May 2011 13:50:23 +0200	[thread overview]
Message-ID: <1304250630-6150-4-git-send-email-jengelh@medozas.de> (raw)
In-Reply-To: <1304250630-6150-1-git-send-email-jengelh@medozas.de>

If ret was negative, ntohs may make it positive, which is undesired.
