Re: [Qemu-devel] [PATCHv3] qxl: QXL_IO_UPDATE_AREA: pass ram->update_area directly to update_area

[Gerd Hoffmann]

  Hi,

-        QXLRect update = d->ram->update_area;
          qxl_spice_update_area(d, d->ram->update_surface,
-&update, NULL, 0, 0);
+&d->ram->update_area, NULL, 0, 1);

No, -ESECURITY.

With this in place the guest can change the update rect while 
spice-server is working with it.

cheers,
  Gerd
