[IGMP]: workaround for IGMP v1/v2 bug From: David Stevens <dlstevens@us.ibm.com> As explained at: http://www.cs.ucsb.edu/~krishna/igmp_dos/ With IGMP version 1 and 2 it is possible to inject a unicast report to a client which will make it ignore multicast reports sent later by the router. The fix is to only accept the report if is was sent to a multicast or unicast address. Signed-off-by: David S. Miller <davem@davemloft.net>
