dhcpcd-6.6.3 has been released with the following changes:
   * Log which IP address we are ARPing.
   * Only free other ARP states if not assinging an IPv4LL address.
   * Reload global config when running per interface commands.
      This matches the signal behaviour.
   * If we don't have a hardware address, fallback to creating a default
      IAID from the interface name and index as we used to.
   * Loopback interfaces have routes scoped to the host only.
   * If we don't have a hwlen and no clientid has been set, force a DUID
      based ClientID.
   * Disable IPv6RS if a loopback, pointopoint or not a multicast
interface.
   * If allowinterfaces is not specified, allow all configured
interfaces
      to work, such as loopback and ppp.
   * When not daemonising, don't exit on timeout.
   * Zero length UDP packets are not an error condition on the socket.
      Thanks to Michał Kępień.
   * If the IP address is still on the interface when reading a lease,
      fake add the address and routes so the lease can be cleaned up if
needed.

 From dhcpcd-6.3.3 to 6.6.2, dhcpcd was vulnerable to a zero length UDP
packet which would cause the socket to close resulting in a DoS.
For IPv4 sockets, triggering a carrier reset would be enough to re-open
the socket.
For IPv6 sockets, dhcpcd would have to be restarted.
