Subject: netfilter: nft_last: copy content when cloning expression
From: Pablo Neira Ayuso <pablo@xxxxxxxxxxxxx>
commit 860e874290fb3be08e966c9c8ffc510c5b0f2bd8 upstream.
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")
