<andrew.cooper3@xxxxxxxxxx> Date: Wed Oct 10 09:17:15 2018 +0000 x86/vvmx: Disallow the use of VT-x instructions when nested virt is disabled c/s ac6a4500b "vvmx: set vmxon_region_pa of vcpu out of VMX operation to an invalid address" was a real bugfix as described, but has a very subtle bug which results in all VT-x instructions being usable by a guest. The toolstack constructs a guest by issuing: XEN_DOMCTL_createdomain XEN_DOMCTL_max_vcpus and optionally later, HVMOP_set_param to enable nested virt. As a result, the call to nvmx_vcpu_initialise() in hvm_vcpu_initialise() (which is what makes the above patch look correct during review) is actually dead code. In practice, nvmx_vcpu_initialise() first gets called when nested virt is enabled, which is typically never. As a result, the zeroed memory of struct vcpu causes nvmx_vcpu_in_vmx() to return true before nested virt is enabled for the guest. Fixing the order of initialisation is a work in progress for other reasons, but not viable for security backports. A compounding factor is that the vmexit handlers for all instructions, other than VMXON, pass 0 into vmx_inst_check_privilege()'s vmxop_check parameter, which skips the CR4.VMXE check. (This is one of many reasons why nested virt isn't a supported feature yet.) However, the overall result is that when nested virt is not enabled by the toolstack (i.e. the default configuration for all production guests), the VT-x instructions (other than VMXON) are actually usable, and Xen very quickly falls over the fact that the nvmx structure is uninitialised. In order to fail safe in the supported case, re-implement all the VT-x instruction handling using a single function with a common prologue, covering all the checks which should cause #UD or #GP faults. This deliberately doesn't use any state from the nvmx structure, in case there are other lurking issues.
