Subject: Re: [PATCH] virtio: console: check the control packet size before parsing it

Fair enough. I was wrong about the buffer contents and about who
controls the stream. The real issue is that a bad length just makes
the driver act on garbage values, and nothing in the switch derives
a memory access from them, so the patch is hardening, not a fix.
Keeping it withdrawn.
