Subject: [iproute PATCH 6/6] lnstat_util: Make sure buffer is NUL-terminated
Date: Fri, 1 Sep 2017 18:52:56 +0200 [thread overview]
Message-ID: <20170901165256.21459-7-phil@nwl.cc> (raw)
In-Reply-To: <20170901165256.21459-1-phil@nwl.cc>
Can't use strlcpy() here since lnstat is not linked against libutil.
While being at it, fix coding style in that chunk as well.
