Subject: [PATCH 22/53] netfilter: Add the missed return value check of nft_register_chain_type
Date: Mon, 26 Sep 2016 01:06:32 +0200 [thread overview]
Message-ID: <1474844823-2026-23-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1474844823-2026-1-git-send-email-pablo@netfilter.org>
From: Gao Feng <fgao@ikuai8.com>
There are some codes of netfilter module which did not check the return
value of nft_register_chain_type. Add the checks now.
