Corosync 3.0.2 Release Notes

I am pleased to announce the latest maintenance release of Corosync 3.0.2 available immediately from our website at http://build.clusterlabs.org/corosync/releases/ or GitHub release section at https://github.com/corosync/corosync/releases.

This release contains important bug fixes and some of new features. Most notable ones:

• Support for knet nozzle device - Nozzle device is a pseudo ethernet device that routes network traffic through a channel on the corosync knet network (NOT cpg or any corosync internal service) to other nodes in the cluster. This allows applications to take advantage of knet features such as multipathing, automatic failover, link switching etc. Note that libnozzle is not a reliable transport, but you can tunnel TCP through it for reliable communications. For more information, see nozzle section in corosync.conf(5) man page.

• Fix and enhance vqsim - the votequorum simulator

• Add support for knet acls (kronosnet >= 1.10 is required) - this allows blocking of incoming packets from IPs which are not in corosync.conf nodelist when knet is used. Same feature is also available for UDPU. For more information see block_unlisted_ips configuration option described in corosync.conf(5) man page.

• Reintroduce back the secauth configuration option. This feature, together with ability to use shorter key, allows easier migration from corosync 2.x configuration file.
