But there is still a regression regarding the PIM socket behavior not related to the packet format. The pim.c include 2 functions (pim_read and pim_accept) that are called when the socket received a packet: There functions are never triggered when PIM packets are received on 10.0. In the same time igmp_read() and igmp_accept() are correctly triggered on 9.2 and 10.0. tcpdump in non-promiscious mode correctly see input of PIM packet: This should confirm that once this daemon is started, it correctly open a PIM socket and the multicast filter is updated. _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
