      KVM: PPC: Book3S PR: Set hflag to indicate that POWER9 supports 1T segments · 6142236c
      Suraj Jitindar Singh authored 
      When booting a kvm-pr guest on a POWER9 machine the following message is
observed:
"qemu-system-ppc64: KVM does not support 1TiB segments which guest expects"

This is because the guest is expecting to be able to use 1T segments
however we don't indicate support for it. This is because we don't set
the BOOK3S_HFLAG_MULTI_PGSIZE flag in the hflags in kvmppc_set_pvr_pr()
on POWER9.

POWER9 does indeed have support for 1T segments, so add a case for
POWER9 to the switch statement to ensure it is set.

      KVM: PPC: Book3S HV: Fix race between kvm_unmap_hva_range and MMU mode switch · 234ff0b7
      Paul Mackerras authored 
      Testing has revealed an occasional crash which appears to be caused
by a race between kvmppc_switch_mmu_to_hpt and kvm_unmap_hva_range_hv.
The symptom is a NULL pointer dereference in __find_linux_pte() called
from kvm_unmap_radix() with kvm->arch.pgtable == NULL.

Looking at kvmppc_switch_mmu_to_hpt(), it does indeed clear
kvm->arch.pgtable (via kvmppc_free_radix()) before setting
kvm->arch.radix to NULL, and there is nothing to prevent
kvm_unmap_hva_range_hv() or the other MMU callback functions from
being called concurrently with kvmppc_switch_mmu_to_hpt() or
kvmppc_switch_mmu_to_radix().

This patch therefore adds calls to spin_lock/unlock on the kvm->mmu_lock
around the assignments to kvm->arch.radix, and makes sure that the
partition-scoped radix tree or HPT is only freed after changing
kvm->arch.radix.

This also takes the kvm->mmu_lock in kvmppc_rmap_reset() to make sure
that the clearing of each rmap array (one per memslot) doesn't happen
concurrently with use of the array in the kvm_unmap_hva_range_hv()
or the other MMU callbacks.

      kvm: mmu: Fix race in emulated page table writes · 0e0fee5c
      Junaid Shahid authored 
      When a guest page table is updated via an emulated write,
kvm_mmu_pte_write() is called to update the shadow PTE using the just
written guest PTE value. But if two emulated guest PTE writes happened
concurrently, it is possible that the guest PTE and the shadow PTE end
up being out of sync. Emulated writes do not mark the shadow page as
unsync-ed, so this inconsistency will not be resolved even by a guest TLB
flush (unless the page was marked as unsync-ed at some other point).

This is fixed by re-reading the current value of the guest PTE after the
MMU lock has been acquired instead of just using the value that was
written prior to calling kvm_mmu_pte_write().

      KVM: nVMX: vmcs12 revision_id is always VMCS12_REVISION even when copied from eVMCS · 52ad7eb3
      Liran Alon authored 
      vmcs12 represents the per-CPU cache of L1 active vmcs12.

This cache can be loaded by one of the following:
1) Guest making a vmcs12 active by exeucting VMPTRLD
2) Guest specifying eVMCS in VP assist page and executing
VMLAUNCH/VMRESUME.

Either way, vmcs12 should have revision_id of VMCS12_REVISION.
Which is not equal to eVMCS revision_id which specifies used
VersionNumber of eVMCS struct (e.g. KVM_EVMCS_VERSION).

Specifically, this causes an issue in restoring a nested VM state
because vmx_set_nested_state() verifies that vmcs12->revision_id
is equal to VMCS12_REVISION which was not true in case vmcs12
was populated from an eVMCS by vmx_get_nested_state() which calls
copy_enlightened_to_vmcs12().

      KVM: nVMX: Verify eVMCS revision id match supported eVMCS version on eVMCS VMPTRLD · 72aeb60c
      Liran Alon authored 
      According to TLFS section 16.11.2 Enlightened VMCS, the first u32
field of eVMCS should specify eVMCS VersionNumber.

This version should be in the range of supported eVMCS versions exposed
to guest via CPUID.0x4000000A.EAX[0:15].
The range which KVM expose to guest in this CPUID field should be the
same as the value returned in vmcs_version by nested_enable_evmcs().

According to the above, eVMCS VMPTRLD should verify that version specified
in given eVMCS is in the supported range. However, current code
mistakenly verfies this field against VMCS12_REVISION.

One can also see that when KVM use eVMCS, it makes sure that
alloc_vmcs_cpu() sets allocated eVMCS revision_id to KVM_EVMCS_VERSION.

Obvious fix should just change eVMCS VMPTRLD to verify first u32 field
of eVMCS is equal to KVM_EVMCS_VERSION.
However, it turns out that Microsoft Hyper-V fails to comply to their
own invented interface: When Hyper-V use eVMCS, it just sets first u32
field of eVMCS to revision_id specified in MSR_IA32_VMX_BASIC (In our
case: VMCS12_REVISION). Instead of used eVMCS version number which is
one of the supported versions specified in CPUID.0x4000000A.EAX[0:15].
To overcome Hyper-V bug, we accept either a supported eVMCS version
or VMCS12_REVISION as valid values for first u32 field of eVMCS.

      KVM: nVMX/nSVM: Fix bug which sets vcpu->arch.tsc_offset to L1 tsc_offset · 326e7425
      Leonid Shatz authored 
      Since commit e79f245d ("X86/KVM: Properly update 'tsc_offset' to
represent the running guest"), vcpu->arch.tsc_offset meaning was
changed to always reflect the tsc_offset value set on active VMCS.
Regardless if vCPU is currently running L1 or L2.

However, above mentioned commit failed to also change
kvm_vcpu_write_tsc_offset() to set vcpu->arch.tsc_offset correctly.
This is because vmx_write_tsc_offset() could set the tsc_offset value
in active VMCS to given offset parameter *plus vmcs12->tsc_offset*.
However, kvm_vcpu_write_tsc_offset() just sets vcpu->arch.tsc_offset
to given offset parameter. Without taking into account the possible
addition of vmcs12->tsc_offset. (Same is true for SVM case).

Fix this issue by changing kvm_x86_ops->write_tsc_offset() to return
actually set tsc_offset in active VMCS and modify
kvm_vcpu_write_tsc_offset() to set returned value in
vcpu->arch.tsc_offset.
In addition, rename write_tsc_offset() callback to write_l1_tsc_offset()
to make it clear that it is meant to set L1 TSC offset.

      KVM: VMX: Update shared MSRs to be saved/restored on MSR_EFER.LMA changes · f48b4711
      Liran Alon authored 
      When guest transitions from/to long-mode by modifying MSR_EFER.LMA,
the list of shared MSRs to be saved/restored on guest<->host
transitions is updated (See vmx_set_efer() call to setup_msrs()).

On every entry to guest, vcpu_enter_guest() calls
vmx_prepare_switch_to_guest(). This function should also take care
of setting the shared MSRs to be saved/restored. However, the
function does nothing in case we are already running with loaded
guest state (vmx->loaded_cpu_state != NULL).

This means that even when guest modifies MSR_EFER.LMA which results
in updating the list of shared MSRs, it isn't being taken into account
by vmx_prepare_switch_to_guest() because it happens while we are
running with loaded guest state.

To fix above mentioned issue, add a flag to mark that the list of
shared MSRs has been updated and modify vmx_prepare_switch_to_guest()
to set shared MSRs when running with host state *OR* list of shared
MSRs has been updated.

Note that this issue was mistakenly introduced by commit
678e315e ("KVM: vmx: add dedicated utility to access guest's
kernel_gs_base") because previously vmx_set_efer() always called
vmx_load_host_state() which resulted in vmx_prepare_switch_to_guest() to
set shared MSRs.

      KVM: nVMX: Fix kernel info-leak when enabling KVM_CAP_HYPERV_ENLIGHTENED_VMCS more than once · 7f9ad1df
      Liran Alon authored 
      Consider the case that userspace enables KVM_CAP_HYPERV_ENLIGHTENED_VMCS twice:
1) kvm_vcpu_ioctl_enable_cap() is called to enable
KVM_CAP_HYPERV_ENLIGHTENED_VMCS which calls nested_enable_evmcs().
2) nested_enable_evmcs() sets enlightened_vmcs_enabled to true and fills
vmcs_version which is then copied to userspace.
3) kvm_vcpu_ioctl_enable_cap() is called again to enable
KVM_CAP_HYPERV_ENLIGHTENED_VMCS which calls nested_enable_evmcs().
4) This time nested_enable_evmcs() just returns 0 as
enlightened_vmcs_enabled is already true. *Without filling
vmcs_version*.
5) kvm_vcpu_ioctl_enable_cap() continues as usual and copies
*uninitialized* vmcs_version to userspace which leads to kernel info-leak.

Fix this issue by simply changing nested_enable_evmcs() to always fill
vmcs_version output argument. Even when enlightened_vmcs_enabled is
already set to true.

Note that SVM's nested_enable_evmcs() should not be modified because it
always returns a non-zero value (-ENODEV) which results in
kvm_vcpu_ioctl_enable_cap() skipping the copy of vmcs_version to
userspace (as it should).
