The following patchset fills the next gaps in the multicast address rules page by adding support for group-aware optimizations for multicast addresses of scope greater than link-local. So far, only link-local addresses were optimized as packets with routeable addresses not only need to be forwarded to local multicast listeners but also multicast routers. "Handling rules depending on multicast address:" [0] Before: * Ipv4, link-local: supported without bridges * IPv6, link-local: supported * IPv4, routeable: support planned. * IPv6, routeable: support planned. After: * Ipv4, link-local: supported without bridges * IPv6, link-local: supported * IPv4, routeable: supported without bridges. * IPv6, routeable: supported. Patch 1 adds the detection of multicast routers and announces them via two new flags in its multicast TVLV. TVLV receivers will memorize this and fill lists similar to how we already do for the WANT_ALL_IPV4/IPV6 flags. Currently the detection for bridged-in IPv6 multicast routers is not quite what the RFC for multicast router discovery suggests. But once the MRD implementation in the Linux bridge has matured a bit, I'm going to swap this simplified approach with tapping into the bridge once more, asking the bridge for the presence of multicast routers on the link. (This will then also add support for "IPv4, routeable, with bridges") Then patch 2 implements the changes to the forwarding plane, utilizing the new information we have gathered with the second patch. This patchset is rebased to: "[PATCH v3 0/3] batman-adv: routeable multicast preparations" https://patchwork.open-mesh.org/project/b.a.t.m.a.n./list/?series=252 Regards, Linus [0]: https://www.open-mesh.org/projects/batman-adv/wiki/Multicast-optimizations-tech#Handling-rules-depending-on-multicast-address --- Changelog v2: * rebased to master * split patchset in two with the intention to ease reviewing (no code changes, just the last two patches here) * removed unncessarilly added newline in batadv_mcast_flags_log() [PATCH 5/6] / [PATCH v2 1/2] * kerneldoc: @BATADV_MCAST_NO_WANT_ALL_RTR6 -> -"NO_" in enum batadv_mcast_flags [PATCH 5/6] / [PATCH v2 1/2]
