Hi Rafael, others, It looks like your commit to ip_mroute.[ch] from January 11th broke multicast forwarding. I found another thread that may suffer from the same problem: http://marc.info/?l=openbsd-bugs&m=148605155027668&w=2 - I'm CC:'ing the OP from that thread here (hope you don't mind :).

I use a settopbox that utilizes multicast streaming from my provider to watch television with the net/igmpproxy port. Using an archive of older kernels, I determined things broke between bsd.mp.2017-01-10_21:40:04.127 and bsd.mp.2017-01-11_14:22:26.129 (build times and kernel version numbers as found in the snapshot bsd.mp kernel using what(1)). After bisecting and building a bunch of kernels, I found this commit broke things for me: building source that's current as of 2017-01-11 14:00 (CET) gives a kernel that forwards multicast traffic as configured, while source from 10 minutes later doesn't (checked out with `cvs -q up -D "2017-01-11 14:10" -PAd`); with the ip_mroute.[ch] change the only difference between the two trees. When things work, I see multicast traffic coming in on the upstream interface and go out on the downstream interface. With the change in, tcpdump shows the traffic on the upstream interface, but there's no traffic forwarded to the downstream interface. Both interfaces are vlan(4) devices. The only change I make between reboots is the kernel, the rest of the configuration doesn't change.
