Subject: [PATCH 23/28] netfilter: nft_dynset: validate set expression definition
Date: Mon, 30 Mar 2020 21:21:31 +0200 [thread overview]
Message-ID: <20200330192136.230459-24-pablo@netfilter.org> (raw)
In-Reply-To: <20200330192136.230459-1-pablo@netfilter.org>
If the global set expression definition mismatches the dynset
expression, then bail out.
