bridge: export knowledge about the presence of IGMP/MLD queriers

2014-07-08T23:12:53Z

With this patch other modules are able to ask the bridge whether an IGMP or MLD querier exists on the according, bridged link layer. Multicast snooping can only be performed if a valid, selected querier exists on a link. Just like the bridge only enables its multicast snooping if a querier exists, e.g. batman-adv too can only activate its multicast snooping in bridged scenarios if a querier is present. For instance this export avoids having to reimplement IGMP/MLD querier message snooping and parsing in e.g. batman-adv, when multicast optimizations for bridged scenarios are added in the future.

bridge: adding stubs for multicast exports

2014-07-08T23:12:53Z

To make users (e.g. batman-adv soon) load- and runnable even if the bridge was compiled without snooping capabilities - or even if the kernel was compiled without any bridge code at all. Signed-off-by: Linus Lüssing Signed-off-by: David S. Miller

bridge: memorize and export selected IGMP/MLD querier port

2014-06-11T06:50:47Z

Adding bridge support to the batman-adv multicast optimization requires batman-adv knowing about the existence of bridged-in IGMP/MLD queriers to be able to reliably serve any multicast listener behind this same bridge. Signed-off-by: Linus Lüssing Signed-off-by: David S. Miller

bridge: add export of multicast database adjacent to net_dev

2014-06-11T06:50:47Z

With this new, exported function br_multicast_list_adjacent(net_dev) a list of IPv4/6 addresses is returned. This list contains all multicast addresses sensed by the bridge multicast snooping feature on all bridge ports of the bridge interface of net_dev, excluding addresses from the specified net_device itself. Adding bridge support to the batman-adv multicast optimization requires batman-adv knowing about the existence of bridged-in multicast listeners to be able to reliably serve them with multicast packets.

netfilter: ebtables: make broute table work again

2011-01-11T22:55:51Z

broute table init hook sets up the "br_should_route_hook" pointer, which then gets called from br_input. commit a386f99025f13b32502fe5dedf223c20d7283826 (bridge: add proper RCU annotation to should_route_hook) introduced a typedef, and then changed this to: br_should_route_hook_t *rhook; [..] rhook = rcu_dereference(br_should_route_hook); if (*rhook(skb)) problem is that "br_should_route_hook" contains the address of the function, so calling *rhook() results in kernel panic.

bridge: add proper RCU annotation to should_route_hook

2010-11-15T19:13:16Z

Add br_should_route_hook_t typedef, this is the only way we can get a clean RCU implementation for function pointer. Move route_hook to location where it is used. Signed-off-by: Eric Dumazet Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

net: replace hooks in __netif_receive_skb V5

2010-06-02T14:11:15Z

What this patch does is it removes two receive frame hooks (for bridge and for macvlan) from __netif_receive_skb. These are replaced them with a single hook for both. It only supports one hook per device because it makes no sense to do bridging and macvlan on the same device. Then a network driver (of virtual netdev like macvlan or bridge) can register an rx_handler for needed net device. Signed-off-by: Jiri Pirko Signed-off-by: Stephen Hemminger Signed-off-by: David S.
