Subject: [PATCH AUTOSEL 4.20 086/117] netfilter: ipt_CLUSTERIP: fix deadlock in netns exit routine
Date: Tue, 8 Jan 2019 14:25:54 -0500 [thread overview]
Message-ID: <20190108192628.121270-86-sashal@kernel.org> (raw)
In-Reply-To: <20190108192628.121270-1-sashal@kernel.org>
From: Taehee Yoo <ap420073@gmail.com>
[ Upstream commit 5a86d68bcf02f2d1e9a5897dd482079fd5f75e7f ]
When network namespace is destroyed, cleanup_net() is called.
cleanup_net() holds pernet_ops_rwsem then calls each ->exit callback.
So that clusterip_tg_destroy() is called by cleanup_net().
And clusterip_tg_destroy() calls unregister_netdevice_notifier().
But both cleanup_net() and clusterip_tg_destroy() hold same
lock(pernet_ops_rwsem). hence deadlock occurrs.
After this patch, only 1 notifier is registered when module is inserted.
And all of configs are added to per-net list.
test commands:
%ip netns add vm1
%ip netns exec vm1 bash
%ip link set lo up
%iptables -A INPUT -p tcp -i lo -d 192.168.0.5 --dport 80 \
-j CLUSTERIP --new --hashmode sourceip \
--clustermac 01:00:5e:00:00:20 --total-nodes 2 --local-node 1
%exit
%ip netns del vm1
splat looks like:
