Subject: [PATCH v2 0/4] vvmx: fix L1 vmxon
Date: Wed, 14 Dec 2016 18:11:41 +0800 [thread overview]
Message-ID: <20161214101145.11171-1-haozhong.zhang@intel.com> (raw)
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
