• 73da4268f   vfio-mdev: remove some dead code ... Browse Code »

  We set info.count to 1 in mtty_get_irq_info() so static checkers
  complain that, "Why do we have impossible conditions?" The answer is
  that it seems to be left over dead code that can be safely removed.

• 5c677869e   vfio-mdev: buffer overflow in ioctl() ... Browse Code »

  This is a sample driver for documentation so the impact is probably
  pretty low. But we should check that bar_index is valid so we
  don't write beyond the end of the mdev_state->region_info[] array.

• 6ed0993a0   vfio-mdev: return -EFAULT if copy_to_user() fails ... Browse Code »

  The copy_to_user() function returns the number of bytes which it wasn't
  able to copy but we want to return a negative error code.

  Rather than hoping for good behavior by marking some elements
  internal, enforce it by making the entire structure private and
  creating an accessor function for the one useful external field.
