dereferences vcpu->arch.book3s which was previously freed by # kvmppc_core_vcpu_free_pr(). This happens because kvmppc_mmu_destroy() # is called after kvmppc_core_vcpu_free() since commit ff030fdf5573 # ("KVM: PPC: Move kvm_vcpu_init() invocation to common code"). # # The kvmppc_mmu_destroy() helper calls one of the following depending # on the KVM backend: # # - kvmppc_mmu_destroy_hv() which does nothing (Book3s HV) # # - kvmppc_mmu_destroy_pr() which undoes the effects of # kvmppc_mmu_init() (Book3s PR 32-bit) # # - kvmppc_mmu_destroy_pr() which undoes the effects of # kvmppc_mmu_init() (Book3s PR 64-bit) # # - kvmppc_mmu_destroy_e500() which does nothing (BookE e500/e500mc) # # It turns out that this is only relevant to PR KVM actually. And both # 32 and 64 backends need vcpu->arch.book3s to be valid when calling # kvmppc_mmu_destroy_pr(). So instead of calling kvmppc_mmu_destroy() # from kvm_arch_vcpu_destroy(), call kvmppc_mmu_destroy_pr() at the # beginning of kvmppc_core_vcpu_free_pr(). This is consistent with # kvmppc_mmu_init() being the last call in kvmppc_core_vcpu_create_pr(). # # For the same reason, if kvmppc_core_vcpu_create_pr() returns an # error then this means that kvmppc_mmu_init() was either not called # or failed, in which case kvmppc_mmu_destroy() should not be called. # Drop the line in the error path of kvm_arch_vcpu_create(). # # Fixes: ff030fdf5573
