[Xen-devel] [PATCH v2 0/4] vvmx: fix L1 vmxon

[Haozhong Zhang <haozhong.zhang@xxxxxxxxx>]

This patchset fixes bugs and adds missing checks in nvmx_handle_vmxon(),
in order to make it more consistent to Intel SDM (section "VMXON - Enter
VMX Operation" in Vol 3).

Changes in v2:
 * Add necessary 'const' in patch 1. (Andrew Cooper)
 * Use the existing INVALID_PADDR rather than introducing a new
   one in patch 1. (Jan Beulich)
 * Add patch 4 to replace VMCX_EADDR by INVALID_PADDR. (Jan Beulich)

Haozhong Zhang (4):
  vvmx: set vmxon_region_pa of vcpu out of VMX operation to an invalid address
  vvmx: return VMfail to L1 if L1 vmxon is executed in VMX operation
  vvmx: check the operand of L1 vmxon
  nestedhvm: replace VMCX_EADDR by INVALID_PADDR
