Hello, I'm testing multicast routing on FreeBSD 9.3 and I have a question:
In packet reception, it seems the packet is received locally as many times the packet is rerouted + 1: ip_input -> ip_mforward -> ip_output (as many times there are dst interfaces in the route cache entry) -> ip_mloopback -> if_simloop (rcvif becomes the ifp of the output interface) -> ip_input -> ip_mforward -> ... In ip_input, after each ip_mforward call, the packet is processed locally (using the goto "ours:") Futhermore it seems this infinite loop is actually broken thanks to a test in ip_mforward that checks the ifp is the same as the registered one in the cache entry. Maybe I missed something, but it does not seem to be working as expected. What do you think?
