From: Paul Mackerras <paulus@samba.org> To: Alexander Graf <agraf@suse.de> Cc: kvm-ppc@vger.kernel.org, kvm@vger.kernel.org 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.
