Hi everyone, I've been working on a port of Wilbert de Graaf's (wilbert@kloosterhof.com) IGMPv3 implementation for FreeBSD to Linux 2.4.x. A tarball containing the patch (against Linux 2.4.6), documentation, and some test programs demonstrating use of the new multicast source filter (MSF) API is available at ftp://ftpeng.cisco.com/igmpv3linux/igmpv3linux-v0003.tar.gz This is alpha quality software, and there is still a good amount of work to be done, but it's reached a stage where some people may find it useful. Also, I'm anxious to receive feedback on both the high-level approach and on any specific problems that people detect. Known limitations are: - ip_mc_destroy_dev() not yet implemented - probable concurrency issues - Only traditional struct ip_mreq accepted by MSF API functions; no support for struct ip_mreqn (i.e. identification of join interface by ifindex). - ip_mc_inc_group() and ip_mc_dec_group() internal interface used by GRE not yet implemented. - Source filters not used for raw socket delivery, only for UDP delivery - Coarse-grained locking - Protocol-independent MSF API not implemented The web page for the original FreeBSD implementation is in the middle of being migrated to http://www.kloosterhof.com/~wilbert/igmpv3.html.
