  "message": "spapr_vty: lookup should only return valid VTY objects\n\nIf a guest passes the reg property of a valid VIO object that is not a VTY\nto either H_GET_TERM_CHAR or H_PUT_TERM_CHAR, QEMU hits a dynamic cast\nassertion and aborts.\n\nPAPR+ says \"Hypervisor checks the termno parameter for validity against the\nVterm IOA unit addresses assigned to the partition, else return H_Parameter.\"\n\nThis patch adds a type check to ensure vty_lookup() either returns a pointer\nto a valid VTY object or NULL.  H_GET_TERM_CHAR and H_PUT_TERM_CHAR will\nnow return H_PARAMETER to the guest instead of crashing.\n\nThe patch has no effect on the reg \u003d\u003d 0 hack used to implement the RTAS call\ndisplay-character.\n\nSigned-off-by: Greg Kurz \u003cgkurz@linux.vnet.ibm.com\u003e\nSigned-off-by: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\nSigned-off-by: Alexander Graf \u003cagraf@suse.de\u003e\n",
