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 Signed-off-by: Christine Caulfield <ccaulfie@redhat.com>
