Subject: [PATCH 4.4 03/20] ipv6: pointer math error in ip6_tnl_parse_tlv_enc_lim()
Date: Thu, 16 Feb 2017 09:53:33 -0800	[thread overview]
Message-ID: <20170216175259.655455702@linuxfoundation.org> (raw)
In-Reply-To: <20170216175259.514980415@linuxfoundation.org>

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@oracle.com>


[ Upstream commit 63117f09c768be05a0bf465911297dc76394f686 ]

Casting is a high precedence operation but "off" and "i" are in terms of
bytes so we need to have some parenthesis here.
