Subject: [nf PATCH] netfilter: nft_limit: Clone packet limits' cost value
Date: Tue, 24 May 2022 14:50:01 +0200 [thread overview]
Message-ID: <20220524125001.25881-1-phil@nwl.cc> (raw)
When cloning a packet-based limit expression, copy the cost value as
well. Otherwise the new limit is not functional anymore.
Fixes: 3b9e2ea6c11bf ("netfilter: nft_limit: move stateful fields out of expression data")
