Subject: [PATCH 4.4 30/34] ipv4: frags: precedence bug in ip_expire()
Date: Thu, 7 Feb 2019 12:42:12 +0100 [thread overview]
Message-ID: <20190207113026.725752897@linuxfoundation.org> (raw)
In-Reply-To: <20190207113025.552605181@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
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.")
