Subject[PATCH 5.15 137/247] netfilter: nf_tables: always initialize flowtable hook list in transaction
Date
From: Pablo Neira Ayuso <pablo@netfilter.org>

[ Upstream commit 2c9e4559773c261900c674a86b8e455911675d71 ]

The hook list is used if nft_trans_flowtable_update(trans) == true. However,
initialize this list for other cases for safety reasons.

Fixes: 78d9f48f7f44 ("netfilter: nf_tables: add devices to existing flowtable")
