Subject: [B.A.T.M.A.N.] [PATCHv3 net-next 0/2] Exporting IGMP/MLD checking from bridge code
Date: Sat, 2 May 2015 14:01:05 +0200 [thread overview]
Message-ID: <1430568067-6912-1-git-send-email-linus.luessing@c0d3.blue> (raw)
The multicast optimizations in batman-adv are yet only usable and
enabled in non-bridged scenarios. To be able to support bridged setups
batman-adv needs to be able to detect IGMP/MLD queriers and reports on
mesh nodes without bridges, too. See the following link for details:
http://www.open-mesh.org/projects/batman-adv/wiki/Multicast-optimizations-listener-reports
To avoid duplicate code between the bridge and batman-adv, the IGMP/MLD
message validation code is moved from the bridge to the IPv4/IPv6 stack.
On the way, some refactoring to increase readability and to iron out
some subtle differences between the IGMP and MLD parsing code is done.
Cheers, Linus
Changelog v3:
* changed interface / restructuring of skb_checksum_trimmed()
* kernel doc for skb_checksum_trimmed()/skb_checksum_maybe_trim()
* fixed a memory leak in the cloned skb case in skb_checksum_trimmed()
* fixed transport_len calculation in __ipv6_mc_check_mld(),
make it relative to the skb transport header offset
(= exclude the hop-by-hop option size in transport_len)
Changelog v2:
* Updated copyright for mcast_snoop.c
