Subject: [PATCH 00/14] KVM changes for 3.18-rc2
Date: Fri, 24 Oct 2014 17:07:11 +0200	[thread overview]
Message-ID: <1414163245-18555-1-git-send-email-pbonzini@redhat.com> (raw)

This is a pretty large update.  I think it is roughly as big
as what I usually had for the _whole_ rc period.

There are a few bad bugs where the guest can OOPS or crash the host.  We
have also started looking at attack models for nested virtualization;
bugs that usually result in the guest ring 0 crashing itself become
more worrisome if you have nested virtualization, because the nested
guest might bring down the non-nested guest as well.  For current
uses of nested virtualization these do not really have a security
impact, but you never know and bugs are bugs nevertheless.

A lot of these bugs are in 3.17 too, resulting in a large number of
stable@ Ccs.  I checked that all the patches apply there with no
conflicts.

I will send this out to Linus in a second.
