From 5a645dd86c1be64728578bcb1bdfb96e21815acb Mon Sep 17 00:00:00 2001 From: Julien Gomes Date: Tue, 20 Jun 2017 13:54:17 -0700 Subject: ipmr: add netlink notifications on igmpmsg cache reports Add Netlink notifications on cache reports in ipmr, in addition to the existing igmpmsg sent to mroute_sk. Send RTM_NEWCACHEREPORT notifications to RTNLGRP_IPV4_MROUTE_R. MSGTYPE, VIF_ID, SRC_ADDR and DST_ADDR Netlink attributes contain the same data as their equivalent fields in the igmpmsg header. PKT attribute is the packet sent to mroute_sk, without the added igmpmsg header. Suggested-by: Ryan Halbrook Signed-off-by: Julien Gomes Reviewed-by: Nikolay Aleksandrov Signed-off-by: David S.
