Date: Fri,  6 Dec 2019 18:12:58 -0500	[thread overview]
Message-ID: <20191206231302.3466-1-krish.sadhukhan@oracle.com> (raw)

According to section "Checks on Guest Control Registers, Debug Registers, and
and MSRs" in Intel SDM vol 3C, the following checks are performed on vmentry
of nested guests:

    "The IA32_SYSENTER_ESP field and the IA32_SYSENTER_EIP field must each
     contain a canonical address."

Patch# 1: Adds the required KVM checks.
Patch# 2: Modifies an existing kvm-unit-test function to suit the new test
	  being added as part of this KVM check.
Patch# 3: Removes a redundant function from the test suite.
Patch# 4: Adds a kvm-unit-test to validate this new KVM check.
