Subject: [PATCH net-next] netfilter: nf_tables: fix wrong pointer passed to PTR_ERR()
Date: Thu, 19 Jan 2023 15:51:25 +0800 [thread overview]
Message-ID: <20230119075125.3598627-1-yangyingliang@huawei.com> (raw)
It should be 'chain' passed to PTR_ERR() in the error path
after calling nft_chain_lookup() in nf_tables_delrule().
Fixes: f80a612dd77c ("netfilter: nf_tables: add support to destroy operation")
