Subject: [patch] ipv6: pointer math error in ip6_tnl_parse_tlv_enc_lim()
Date: Wed, 01 Feb 2017 08:46:32 +0000 [thread overview]
Message-ID: <20170201084632.GA29912@mwanda> (raw)
Casting is a high precedence operation but "off" and "i" are in terms of
bytes so we need to have some parenthesis here.
Fixes: fbfa743a9d2a ("ipv6: fix ip6_tnl_parse_tlv_enc_lim()")
