Subject: [PATCH 3/3] fix incorrect snprintf usage
Date: Tue, 24 Jun 2014 09:05:30 -0700 [thread overview]
Message-ID: <20140624090530.56318f6f@nehalam.linuxnetplumber.net> (raw)
In-Reply-To: <20140624090253.140206a7-We1ePj4FEcvRI77zikRAJc56i+j3xesD0e7PPNI6Mm0@public.gmane.org>
Now that snprintf is used, Gcc finds more uses of unsafe arguments.
Fix where found. These may have already been fixed by
other patches on the mailing list.
