        nullfs(5)

        The nullfs(5) implementation of the VOP_LINK(9) VFS operation does not
        check whether the source and target of the link are both in the same
        nullfs instance.  It is therefore possible to create a hardlink from a
        location in one nullfs instance to a file in another, as long as the
        underlying (source) filesystem is the same.

        ifioctl

        As is commonly the case, the IPv6 and ATM network layer ioctl request
        handlers are written in such a way that an unrecognized request is
        passed on unmodified to the link layer, which will either handle it or
        return an error code.

        Network interface drivers, however, assume that the SIOCSIFADDR,
        SIOCSIFBRDADDR, SIOCSIFDSTADDR and SIOCSIFNETMASK requests have been
        handled at the network layer, and therefore do not perform input
        validation or verify the caller's credentials.  Typical link-layer
        actions for these requests may include marking the interface as "up"
        and resetting the underlying hardware.
