We've been applying this patch since the fix was discovered but i just
realized yesterday when building a new kernel that the Xen kernel does
not have this fix applied yet.
I also have verified that this exploit works to gain root access on the
current http://xenbits.xensource.com/linux-2.6.18-xen.hg branch
It has to be said, very clearly, that our 2.6.18 tree is only really of use
now as a repository of Xen patches for vendors to pull into their own,
*properly maintained and secured* kernels. We are very interested in fixing
Xen-related security issues in our 2.6.18 tree (precisely because others use
it as a repository of good Xen patches). We are less interested in general
kernel fixes, although of course as a matter of good form we will consider a
security fix such as you propose. However, the patch you supplied does not
apply to the 2.6.18 tree.
Thanks,
Keir
I see, good to know, thanks!
