Subject: [iproute PATCH v2 7/7] tc/q_multiq: Don't pass garbage in TCA_OPTIONS
Date: Thu, 17 Aug 2017 19:09:31 +0200 [thread overview]
Message-ID: <20170817170931.24302-8-phil@nwl.cc> (raw)
In-Reply-To: <20170817170931.24302-1-phil@nwl.cc>
multiq_parse_opt() doesn't change 'opt' at all. So at least make sure
it doesn't fill TCA_OPTIONS attribute with garbage from stack.
