Subject: [PATCH net 2/3] netfilter: nft_last: copy content when cloning expression
Date: Wed,  1 Mar 2023 23:20:20 +0100	[thread overview]
Message-ID: <20230301222021.154670-3-pablo@netfilter.org> (raw)
In-Reply-To: <20230301222021.154670-1-pablo@netfilter.org>

If the ruleset contains last timestamps, restore them accordingly.
Otherwise, listing after restoration shows never used items.

Fixes: 33a24de37e81 ("netfilter: nft_last: move stateful fields out of expression data")
