Subject: [PATCH 4.18 276/350] MIPS: OCTEON: fix out of bounds array access on CN68XX
Date: Sun, 11 Nov 2018 14:22:20 -0800 [thread overview]
Message-ID: <20181111221719.584955923@linuxfoundation.org> (raw)
In-Reply-To: <20181111221707.043394111@linuxfoundation.org>
4.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Aaro Koskinen <aaro.koskinen@iki.fi>
commit c0fae7e2452b90c31edd2d25eb3baf0c76b400ca upstream.
The maximum number of interfaces is returned by
cvmx_helper_get_number_of_interfaces(), and the value is used to access
interface_port_count[]. When CN68XX support was added, we forgot
to increase the array size. Fix that.
Fixes: 2c8c3f0201333 ("MIPS: Octeon: Support additional interfaces on CN68XX")
