Subject: [PATCH 9/9] netfilter: ipt_CLUSTERIP: Fix wrong conntrack netns refcnt usage
Date: Fri, 14 Apr 2017 02:26:51 +0200 [thread overview]
Message-ID: <1492129611-29336-10-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1492129611-29336-1-git-send-email-pablo@netfilter.org>
From: Gao Feng <fgao@ikuai8.com>
Current codes invoke wrongly nf_ct_netns_get in the destroy routine,
it should use nf_ct_netns_put, not nf_ct_netns_get.
It could cause some modules could not be unloaded.
Fixes: ecb2421b5ddf ("netfilter: add and use nf_ct_netns_get/put")
