      kvm: nVMX: fix nested tsc scaling · c95ba92a
      Peter Feiner authored
      
      
      When the host supported TSC scaling, L2 would use a TSC multiplier of
      0, which causes a VM entry failure. Now L2's TSC uses the same
      multiplier as L1.

      KVM: nVMX: postpone VMCS changes on MSR_IA32_APICBASE write · dccbfcf5
      Radim Krčmář authored
      If vmcs12 does not intercept APIC_BASE writes, then KVM will handle the
      write with vmcs02 as the current VMCS.
      This will incorrectly apply modifications intended for vmcs01 to vmcs02
      and L2 can use it to gain access to L0's x2APIC registers by disabling
      virtualized x2APIC while using msr bitmap that assumes enabled.
      
      Postpone execution of vmx_set_virtual_x2apic_mode until vmcs01 is the
      current VMCS.  An alternative solution would temporarily make vmcs01 the
      current VMCS, but it requires more care.

      KVM: nVMX: fix msr bitmaps to prevent L2 from accessing L0 x2APIC · d048c098
      Radim Krčmář authored
      msr bitmap can be used to avoid a VM exit (interception) on guest MSR
      accesses.  In some configurations of VMX controls, the guest can even
      directly access host's x2APIC MSRs.  See SDM 29.5 VIRTUALIZING MSR-BASED
      APIC ACCESSES.
      
      L2 could read all L0's x2APIC MSRs and write TPR, EOI, and SELF_IPI.
      To do so, L1 would first trick KVM to disable all possible interceptions
      by enabling APICv features and then would turn those features off;
      nested_vmx_merge_msr_bitmap() only disabled interceptions, so VMX would
      not intercept previously enabled MSRs even though they were not safe
      with the new configuration.
      
      Correctly re-enabling interceptions is not enough as a second bug would
      still allow L1+L2 to access host's MSRs: msr bitmap was shared for all
      VMCSs, so L1 could trigger a race to get the desired combination of msr
      bitmap and VMX controls.
      
      This fix allocates a msr bitmap for every L1 VCPU, allows only safe
      x2APIC MSRs from L1's msr bitmap, and disables msr bitmaps if they would
      have to intercept everything anyway.
