From: Pablo Neira Ayuso <pablo@xxxxxxxxxxxxx>
commit efefd4f00c967d00ad7abe092554ffbb70c1a793 upstream.
Add missing decorator type to lookup expression and tighten WARN_ON_ONCE
check in pipapo to spot earlier that this is unset.
Fixes: 29b359cf6d95 ("netfilter: nft_set_pipapo: walk over current view on netlink dump")
