Subject: [PATCH net 08/14] netfilter: ipset: make sure gc is properly stopped
Date: Sun, 21 Jun 2026 00:27:32 +0200 [thread overview]
Message-ID: <20260620222738.112506-9-pablo@netfilter.org> (raw)
In-Reply-To: <20260620222738.112506-1-pablo@netfilter.org>
From: Jozsef Kadlecsik <kadlec@netfilter.org>
Sashiko noticed that when destroying a set,
cancel_delayed_work_sync() was called while gc
calls queue_delayed_work() unconditionally which
can lead not to properly shutting down the gc.
Fixes: f66ee0410b1c ("netfilter: ipset: Fix "INFO: rcu detected stall in hash_xxx" reports")
