I have built a new kernel (kernel-2.6.32.21-168.xendom0.fc12) at
http://koji.fedoraproject.org/koji/taskinfo?taskID=2477887 or at the
repository
http://repos.fedorapeople.org/repos/myoung/dom0-kernel/
It includes fixes for the recent x86_64 local root exploit.
There are also some new builds of xen. The Fedora packages
xen-4.0.1-3.fc15 and xen-4.0.1-3.fc14 available via
http://koji.fedoraproject.org/koji/packageinfo?packageID=7 have some IRQ
fixes that solve a problem I was having with a keyboard and mouse and the
patch that disables xsave which was causing problems with HVM (both these
are from 4.0.2-rc1-pre). It also creates a symbolic link for qemu-dm from
the place it was in 3.4.x to where it is in 4.0.x for compatibility.
I also have a temporary test build xen-4.0.1-1.fc13.1 for Fedora 13 at
http://koji.fedoraproject.org/koji/taskinfo?taskID=2478501 . This is
slightly misnamed as it is actually of 4.0.2-rc1-pre and includes the
fixes above. Note that he build system will delete those RPMs
automatically after a week or so.
