  "message": "KVM: PPC: Book3S: Fix incorrect guest-to-user-translation error handling\n\nH_PUT_TCE_INDIRECT handlers receive a page with up to 512 TCEs from\na guest. Although we verify correctness of TCEs before we do anything\nwith the existing tables, there is a small window when a check in\nkvmppc_tce_validate might pass and right after that the guest alters\nthe page of TCEs, causing an early exit from the handler and leaving\nsrcu_read_lock(\u0026vcpu-\u003ekvm-\u003esrcu) (virtual mode) or lock_rmap(rmap)\n(real mode) locked.\n\nThis fixes the bug by jumping to the common exit code with an appropriate\nunlock.\n\nCc: stable@vger.kernel.org # v4.11+\nFixes: 121f80ba68f1 (\"KVM: PPC: VFIO: Add in-kernel acceleration for VFIO\")\nSigned-off-by: Alexey Kardashevskiy \u003caik@ozlabs.ru\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@ozlabs.org\u003e\n",
