# fail_iommu_setup() registers the fail_iommu_bus_notifier struct to both # PCI and VIO buses. struct notifier_block is a linked list node, so this # causes any notifiers later registered to either bus type to also be # registered to the other since they share the same node. # # This causes issues in (at least) the vgaarb code, which registers a # notifier for PCI buses. pci_notify() ends up being called on a vio # device, converted with to_pci_dev() even though it's not a PCI device, # and finally makes a bad access in vga_arbiter_add_pci_device() as # discovered with KASAN: # # BUG: KASAN: slab-out-of-bounds in vga_arbiter_add_pci_device+0x60/0xe00 # Read of size 4 at addr c000000264c26fdc by task swapper/0/1 #
