We are pleased to announce the general availability of kronosnet v1.11
kronosnet (or knet for short) is the new underlying network protocol for
Linux HA components (corosync), that features the ability to use
multiple links between nodes, active/active and active/passive link
failover policies, automatic link recovery, FIPS compliant encryption
(nss and/or openssl), automatic PMTUd and in general better performances
compared to the old network protocol.
Highlights in this release:
* Major bug fixes in the PMTUd code. MTU was not calculated correctly
when using crypto and PMTUd would fail due to timeouts when using
crypto and systems are overloaded. Thanks to the proxmox community for
reporting the issues and testing pre-fixes.
* Allow TX and RX threads to flush queues during shutdown to avoid
dropping outgoing packets.
* Add a new API to allow manual override of PMTUd/MTU. Please use with
caution. (NOTE to package maintainers, this also includes a minor
* Minor internal improvements and bug fixes.
