Subject: [patch 17/26] KVM: VMX: flush TLB with INVEPT on cpu migration
Date: Fri, 09 Oct 2009 16:08:53 -0700 [thread overview]
Message-ID: <20091009231002.272019830@mini.kroah.org> (raw)

[-- Type: text/plain, Size: 981 bytes --]
2.6.31-stable review patch. If anyone has any objections, please let us know.
------------------
From: Marcelo Tosatti <mtosatti@redhat.com>
commit eb5109e311b5152c0614a28d7d615d087f268f19 upstream.
It is possible that stale EPTP-tagged mappings are used, if a
vcpu migrates to a different pcpu.
Set KVM_REQ_TLB_FLUSH in vmx_vcpu_load, when switching pcpus, which
will invalidate both VPID and EPT mappings on the next vm-entry.
