      tty/hvc_console: fix console lock ordering with spinlock · 19fa6e60
      Denis Kirjanov authored
      hvc_remove() takes a spin lock first then acquires the console
      semaphore. This situation can easily lead to a deadlock scenario
      where we call scheduler with spin lock held.

      tty: reset termios state on device registration · 93857edd
      Johan Hovold authored
      Free any saved termios data when registering a tty device so that the
      termios state is reset when reusing a minor number.
      
      This is useful for hot-pluggable buses such as USB where it does not
      make much sense to reuse saved termios data from an unrelated device
      when a new device is later plugged in.
      
      This specifically avoids a situation where the new device does not have
      the carrier-detect signal wired, but the saved termios state has CLOCAL
      cleared, effectively preventing the port from being opened in blocking
      mode as noted by Jan Kundrát <jan.kundrat@cesnet.cz>.
      
      Note that clearing the saved data at deregistration would not work as
      the device could still be open.
      
      Also note that the termios data is not reset for drivers with
      TTY_DRIVER_DYNAMIC_ALLOC set (e.g. legacy pty) as their character device
      is registered at driver registration and could theoretically already
      have been opened (and pty termios state is never saved anyway).

      tty: close race between device register and open · 6a7e6f78
      Johan Hovold authored
      The tty class device is currently not registered until after the
      character device has been registered thereby leaving a small window
      were a racing open could end up with a NULL tty->dev pointer due to the
      class-device lookup failing in alloc_tty_struct.
      
      Close this race by registering the class device before the character
      device while making sure to defer the user-space uevent notification
      until after the character device has been registered.
      
      Note that some tty drivers expect a valid tty->dev and would misbehave
      or crash otherwise. Some line disciplines also currently dereference the
      class device unconditionally despite the fact that not every tty is
      guaranteed to have one (Unix98 pty), but this is being fixed separately.
