[Qemu-devel] [Bug 1586611] Re: usb-hub can not be detached when detach usb device from VM

I found that when I attached an usb device to the VM, the VM would add an usb-hub automatically if there was no usb-hub. After adding an usb-hub,the VM assigned a port to the actual usb device. When detaching the usb device,the qemu only detach the port,without detaching the usb-hub.So when

[Qemu-devel] [PATCH 1/4] vmsvga: move fifo sanity checks to vmsvga_fifo_length

Sanity checks are applied when the fifo is enabled by the guest (SVGA_REG_CONFIG_DONE write). Which doesn't help much if the guest changes the fifo registers afterwards. Move the checks to vmsvga_fifo_length so they are done each time qemu is about to read from the fifo. Fixes: CVE-2016-4454

[Qemu-devel] [PATCH 3/4] vmsvga: shadow fifo registers

The fifo is normal ram. So kvm vcpu threads and qemu iothread can access the fifo in parallel without syncronization. Which in turn implies we can't use the fifo pointers in-place because the guest can try changing them underneath us. So add shadows for them, to make sure the guest can't modify
