The change from v1 is that I have altered the MMIO size check to fail the emulation in case the size exceeds 8 bytes. That brought some cleanups and another fix along with it, we were returning to userspace in case of failure instead of the guest. This has now become an MMIO series, but since the first commit has been reviewed already, I'm leaving it here. v1: https://lore.kernel.org/r/20211223211528.3560711-1-farosas@xxxxxxxxxxxxx Fabiano Rosas (7): KVM: PPC: Book3S HV: Stop returning internal values to userspace KVM: PPC: Fix vmx/vsx mixup in mmio emulation KVM: PPC: Fix mmio length message KVM: PPC: Don't use pr_emerg when mmio emulation fails KVM: PPC: mmio: Queue interrupt at kvmppc_emulate_mmio KVM: PPC: mmio: Return to guest after emulation failure KVM: PPC: mmio: Reject instructions that access more than mmio.data size arch/powerpc/kvm/emulate_loadstore.c | 4 +--- arch/powerpc/kvm/powerpc.c | 24 +++++++++++++++++------- 2 files changed, 18 insertions(+), 10 deletions(-) -- 2.33.1
