Subject: [PATCH RFCv2 0/4] batman-adv: Unicasting multicast reports to querier-node only
Date: Wed,  1 Apr 2015 10:04:35 +0200	[thread overview]
Message-ID: <1427875479-9240-1-git-send-email-linus.luessing@c0d3.blue> (raw)

The last round of multicast patches send to the batman-adv mailinglist
to add support for the multicast optimizations in bridged scenarios, too,
unfortunately had one major conceptual flaw: It could lead to packet loss.
It's not sufficient to have the unicasting of reports implemented on
bridge-nodes only. Nodes without bridges need to treat reports the same
way.

The issue is described in detail here:

https://www.open-mesh.org/projects/batman-adv/wiki/Multicast-optimizations-listener-reports


I'd also be interested in what the netdev/bridge people think about
patches #1 and #2 in particular, therefore including the according mailinglists
now.

Cheers, Linus


Changelog:
v2:
 * various bugfixes (now runtime tested, too - should(tm) work)
 * added netdev+bridge mailinglists
