Re: [Xen-devel] [qemu-upstream-unstable bisection] complete test-amd64-i386-freebsd10-i386

[Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>]

Paul,

do you have an estimate on when it is going to be fixed?

If it is not soon, I would prefer to revert the patch for now to unbreak
tests.

Cheers,

Stefano

>       Xen: Use the ioreq-server API when available
>       
>       The ioreq-server API added to Xen 4.5 offers better security than
>       the existing Xen/QEMU interface because the shared pages that are
>       used to pass emulation request/results back and forth are removed
>       from the guest's memory space before any requests are serviced.
>       This prevents the guest from mapping these pages (they are in a
>       well known location) and attempting to attack QEMU by synthesizing
>       its own request structures. Hence, this patch modifies configure
>       to detect whether the API is available, and adds the necessary
>       code to use the API if it is.
