Subject: [PATCH 8/8] netfilter: nfnetlink: remove static declaration from err_list
Date: Thu, 23 Feb 2017 12:14:09 +0100 [thread overview]
Message-ID: <1487848449-2731-9-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1487848449-2731-1-git-send-email-pablo@netfilter.org>
From: Liping Zhang <zlpnobody@gmail.com>
Otherwise, different subsys will race to access the err_list, with holding
the different nfnl_lock(subsys_id).
But this will not happen now, since ->call_batch is only implemented by
nftables, so the err_list is protected by nfnl_lock(NFNL_SUBSYS_NFTABLES).
