Subject: [PATCH stable 4.9 v2 29/29] ipv4: frags: precedence bug in ip_expire()
Date: Wed, 10 Oct 2018 12:30:17 -0700 [thread overview]
Message-ID: <20181010193017.25221-30-f.fainelli@gmail.com> (raw)
In-Reply-To: <20181010193017.25221-1-f.fainelli@gmail.com>
From: Dan Carpenter <dan.carpenter@oracle.com>
(commit 70837ffe3085c9a91488b52ca13ac84424da1042 upstream)
We accidentally removed the parentheses here, but they are required
because '!' has higher precedence than '&'.
Fixes: fa0f527358bd ("ip: use rb trees for IP frag queue.")
