Hello all. [Sorry for the possible format issues]
I have an update regarding (valid) concern which has been also raised in current thread which is the virtio backend's ability (when using Xen foreign mapping) to map any guest pages without guest "agreement" on that. There is a PoC (with virtio-mmio on Arm) which is based on Juergen Gross’ work to reuse secure Xen grant mapping for the virtio communications. All details are at: https://lore.kernel.org/xen-devel/[email protected]/ https://lore.kernel.org/xen-devel/[email protected]/ -- Regards, Oleksandr Tyshchenko
