x86/video: Don't assume all FB devices are PCI devices

2016-03-15T10:08:26Z

When booting Hyper-V Generation 2 guests KASAN reports the following out-of-bounds access: BUG: KASAN: slab-out-of-bounds in fb_is_primary_device+0x58/0x70 at addr ffff880079cf0eb0 Read of size 8 by task swapper/0/1 ... [] dump_stack+0x63/0x8b [] print_trailer+0xf9/0x150 [] object_err+0x34/0x40 [] kasan_report_error+0x230/0x550 [] kasan_report+0x58/0x60 [] ? ___slab_alloc+0x80/0x490 [] ? fb_is_primary_device+0x58/0x70 [] __asan_load8+0x5d/0x70 [] fb_is_primary_device+0x58/0x70 [] register_framebuffer+0xda/0x5b0 [] ? remove_conflicting_framebuffers+0x50/0x50 ... The issue is caused by the to_pci_dev() call with no check that the given info->device is in fact a PCI device and some FB devices (Hyper-V FB, EFI FB,...) are not. While on it, clean up the function. Signed-off-by: Vitaly Kuznetsov Acked-by: Bjorn Helgaas Cc: Bjorn Helgaas Cc: Cathy Avery Cc: K. Y.

x86: Use vga_default_device() when determining whether an fb is primary

2012-04-24T08:50:17Z

IORESOURCE_ROM_SHADOW is not necessarily an indication that the hardware is the primary device. Add support for using the vgaarb functions and fall back if nothing's set them. Signed-off-by: Matthew Garrett Cc: mingo@redhat.com Acked-by: hpa@zytor.com Signed-off-by: Dave Airlie
