Subject: [-stable,6.1 10/17] netfilter: nf_tables: use correct lock to protect gc_list
Date: Fri, 22 Sep 2023 18:30:22 +0200 [thread overview]
Message-ID: <20230922163029.150988-11-pablo@netfilter.org> (raw)
In-Reply-To: <20230922163029.150988-1-pablo@netfilter.org>
commit 8357bc946a2abc2a10ca40e5a2105d2b4c57515e upstream.
Use nf_tables_gc_list_lock spinlock, not nf_tables_destroy_list_lock to
protect the gc_list.
Fixes: 5f68718b34a5 ("netfilter: nf_tables: GC transaction API to avoid race with control plane")
