I've just committed a bit patch to the master branch of corosync - it is
now all very experimental, and existing pull requests against master
might need to be checked. This starts the work on what will hopefully
Thanks Chrissie, nice work.
I must highlight "it is now all very experimental". Of course we will be
more than happy for feedback/bug reports (like
https://github.com/corosync/corosync/issues/158) but if you want
something working and tested use "needle" branch/official releases.

become corosync 3.0
The commit is to make Kronosnet the new, default, transport for
corosync. It might take a while to get this fully stabilised but I've
been running it myself for a while now and it seems pretty reliable.
Here are the commit notes:
totem: Add Kronosnet transport.
This is a big update that removes RRP & MRP from the codebase
and makes knet the default transport for corosync. UDP & UDPU
are still (currently) supported but are deprecated. Also crypto
and mutiple interfaces are only supported over knet.
To compile this codebase you will need to install libknet from
https://github.com/fabbione/kronosnet
The corosync.conf(5) man page has been updated with info on the new
options. Older config files should still work but many options
have changed because of the knet implementation so configs should
be checked carefully. In particular any cluster using using RRP
over UDP or UDPU will not start as RRP is no longer present. If you
need multiple interface support then you should be using the knet
transport.
Knet brings many benefits to the corosync codebase, it provides support
for more interfaces than RRP (up to 8), will be more reliable in the
event
of network outages and allows dynamic reconfiguration of interfaces.
It also fixes the ifup/ifdown and 127.0.0.1 binding problems that have
plagued corosync/openais from day 1
