Subject: [PATCH AUTOSEL 5.2 22/63] net/sched: act_sample: don't push mac header on ip6gre ingress
Date: Tue, 1 Oct 2019 12:40:44 -0400 [thread overview]
Message-ID: <20191001164125.15398-22-sashal@kernel.org> (raw)
In-Reply-To: <20191001164125.15398-1-sashal@kernel.org>
From: Davide Caratti <dcaratti@redhat.com>
[ Upstream commit 92974a1d006ad8b30d53047c70974c9e065eb7df ]
current 'sample' action doesn't push the mac header of ingress packets if
they are received by a layer 3 tunnel (like gre or sit); but it forgot to
check for gre over ipv6, so the following script:
# tc q a dev $d clsact
# tc f a dev $d ingress protocol ip flower ip_proto icmp action sample \
> group 100 rate 1
# psample -v -g 100
dumps everything, including outer header and mac, when $d is a gre tunnel
over ipv6. Fix this adding a missing label for ARPHRD_IP6GRE devices.
Fixes: 5c5670fae430 ("net/sched: Introduce sample tc action")
