Jay Fenlason 551f4cb9de firewire: prevent userspace from accessing shut down devices ... If userspace ignores the POLLERR bit from poll(), and only attempts to read() the device when POLLIN is set, it can still make ioctl() calls on a device that has been removed from the system. The node_id and generation returned by GET_INFO will be outdated, but INITIATE_BUS_RESET would still cause a bus reset, and GET_CYCLE_TIMER will return data. And if you guess the correct generation to use, you can send requests to a different device on the bus, and get responses back. This patch prevents open, ioctl, compat_ioctl, and mmap against shutdown devices.
