Subject: [PATCH 0/5] KVM: PPC: Fix various bugs and vulnerabilities in HV KVM
Date: Thu, 22 Nov 2012 20:24:42 +1100	[thread overview]
Message-ID: <20121122092442.GA31117@bloggs.ozlabs.ibm.com> (raw)

This series of patches fixes various bugs that we have found recently.
The bugs fixed in patches 1, 3 and 4 are also vulnerabilities where
the guest could cause the host to crash or could access host memory
inappropriately.  The bug fixed in patch 2 could cause the host to
hang or crash after the guest reboots.  The bug fixed in patch 5 is a
simple thinko in the recently-added HPT reading code.

These patches are against Alex Graf's kvm-ppc-next branch.  They only
affect HV code.

The first two patches have been posted previously but got no comments.

Please apply - given the nature of these bugs I'd really like this
series to make it into the 3.8 merge window.

Paul.
