Subject: [PATCH 1/5] netfilter: nft_reject_bridge: enable reject with bridge vlan
Date: Mon, 25 May 2020 23:54:16 +0200 [thread overview]
Message-ID: <20200525215420.2290-2-pablo@netfilter.org> (raw)
In-Reply-To: <20200525215420.2290-1-pablo@netfilter.org>
From: Michael Braun <michael-dev@fami-braun.de>
Currently, using the bridge reject target with tagged packets
results in untagged packets being sent back.
Fix this by mirroring the vlan id as well.
Fixes: 85f5b3086a04 ("netfilter: bridge: add reject support")
