When a bare OPBus object is created\nand destroyed (e.g. by qom-tests), there is no finalize to remove the\nstale entry, leading to a heap-use-after-free when a subsequent\nflatviews_reset iterates the list.\n\nMove address_space_init to the bus realize callback and add the\ncorresponding address_space_destroy in unrealize, following the\nNubusBus pattern. Also fix the memory_region_init owner from NULL to\nthe OPBus object, so the MR is properly parented instead of dangling\nunder the \"unattached\" container.\n\nFixes: eb04c35da2c0 (\"hw/fsi: Aspeed APB2OPB & On-chip peripheral bus\")\nSigned-off-by: Marc-André Lureau <marcandre.lureau@redhat.com>\n---\n hw/fsi/aspeed_apb2opb.c | 24 +++++++++++++++++++++++-\n 1 file changed, 23 insertions(+), 1 deletion(-)", "diff": "diff --git a/hw/fsi/aspeed_apb2opb.c b/hw/fsi/aspeed_apb2opb.c\nindex b9d72f3ecf6..36092468391 100644\n--- a/hw/fsi/aspeed_apb2opb.c\n+++ b/hw/fsi/aspeed_apb2opb.c\n@@ -348,15 +348,37 @@ static void fsi_opb_init(Object *o)\n {\n OPBus *opb = OP_BUS(o);\n \n- memory_region_init(&opb->mr, 0, TYPE_FSI_OPB, UINT32_MAX);\n+ memory_region_init(&opb->mr, o, TYPE_FSI_OPB, UINT32_MAX);\n+}\n+\n+static void fsi_opb_realize(BusState *bus, Error **errp)\n+{\n+ OPBus *opb = OP_BUS(bus);\n+\n address_space_init(&opb->as, &opb->mr, TYPE_FSI_OPB);\n }\n \n+static void fsi_opb_unrealize(BusState *bus)\n+{\n+ OPBus *opb = OP_BUS(bus);\n+\n+ address_space_destroy(&opb->as);\n+}\n+\n+static void fsi_opb_class_init(ObjectClass *klass, const void *data)\n+{\n+ BusClass *bc = BUS_CLASS(klass);\n+\n+ bc->realize = fsi_opb_realize;\n+ bc->unrealize = fsi_opb_unrealize;\n+}\n+\n static const TypeInfo opb_info = {\n .name = TYPE_OP_BUS,\n .parent = TYPE_BUS,\n .instance_init = fsi_opb_init,\n .instance_size = sizeof(OPBus),\n+ .class_init = fsi_opb_class_init,\n };\n \n static void fsi_opb_register_types(void)\n", "prefixes": [ "v2", "33/46" ] }
