Subject: [PATCH 4.9 38/54] team: set dev->needed_headroom in team_setup_by_port()
Date: Mon, 12 Oct 2020 15:27:00 +0200 [thread overview]
Message-ID: <20201012132631.344152387@linuxfoundation.org> (raw)
In-Reply-To: <20201012132629.585664421@linuxfoundation.org>
From: Eric Dumazet <edumazet@google.com>
commit 89d01748b2354e210b5d4ea47bc25a42a1b42c82 upstream.
Some devices set needed_headroom. If we ignore it, we might
end up crashing in various skb_push() for example in ipgre_header()
since some layers assume enough headroom has been reserved.
Fixes: 1d76efe1577b ("team: add support for non-ethernet devices")
