xen: Reduce attack surface #34

Closed RA-Kooi closed 2 months ago

RA-Kooi commented 2 months ago

Disabling grant tables v2 is a significant reduction in attack surface and they're not used anywhere.

TSX is a feature that's being dropped by Intel for having speculative bugs in it. Disable it preemptively.

The TSX patch doesn't appear to apply cleanly. It looks like this-- or something like it-- is already in the xen repo. Can you confirm, or do we need to adapt the patch?

Had to rebase it on the new commits in upstream. Also rebased my XenServer cherry picks while I'm at it.
