[Xen-devel] [PATCH for-4.13 0/2] x86/hvm: Multiple corrections to task switch handling

Posted by Andrew Cooper 4 years, 5 months ago

These patches want backporting due to the severity of patch 2.  They should
therefore be considered for 4.13 at this point.

  x86/vtx: Fix fault semantics for early task switch failures
  x86/svm: Write the correct %eip into the outgoing task

Is there a matching XTF test to exercise this functionality?

Thanks, Roger.

Modification of an existing one to begin with (which is how I spotted
the problems).

I don't have a CI-ready test yet.
