Subject: [PATCH 5.8 22/56] net: sched: initialize with 0 before setting erspan md->u
Date: Fri, 25 Sep 2020 14:48:12 +0200	[thread overview]
Message-ID: <20200925124731.152136754@linuxfoundation.org> (raw)
In-Reply-To: <20200925124727.878494124@linuxfoundation.org>

From: Xin Long <lucien.xin@gmail.com>

[ Upstream commit 8e1b3ac4786680c2d2b5a24e38a2d714c3bcd1ef ]

In fl_set_erspan_opt(), all bits of erspan md was set 1, as this
function is also used to set opt MASK. However, when setting for
md->u.index for opt VALUE, the rest bits of the union md->u will
be left 1. It would cause to fail the match of the whole md when
version is 1 and only index is set.

This patch is to fix by initializing with 0 before setting erspan
md->u.
