Currently, all ipmr/ip6mr cache reports are sent through the mroute/mroute6 socket only. This forces the use of a single socket for mroute programming, cache reports and, regarding ipmr, IGMP messages without Router Alert option reception.
The present patches are aiming to send Netlink notifications in addition to the existing igmpmsg/mrt6msg to give user programs a way to handle cache reports in parallel with multiple sockets other than the mroute/mroute6 socket.
