We are pleased to announce the general availability of kronosnet v1.0
kronosnet (or knet for short) is the new underlying network protocol
for Linux HA components (corosync), that features 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.
The source tarballs can be downloaded here:

Known issues in this release:
* Knet will fail to work on Fedora 26 arm when built with clang. This is
a known issue with clang compiler that is fixed in more recent
versions of clang.
* Knet will fail to build with clang on rhel7 + epel version of clang.
This is a known issue with clang compiler that is fixed in more recent
versions of clang.
* Running the knet test suite with valgrind (make check-memcheck) will
fail with Debian Experimental glibc due to a known bug in valgrind.
* Running the knet test suite with valgrind on FreeBSD is no longer
supported. The valgrind version on FreeBSD is too old and generates
too many false positives. Also, please refer to build-aux/check.mk on
how to use valgrind in combination with knet. Some platforms requires
extra options to work properly.
* If you are planning to develop plugins, please be aware of this issue:

The knet developer team
recently, I've come across this test comparing OpenVPN vs. SSH
so natutally, I guess it would be interesting to perform similar
test cases in a Kronosnet - OpenVPN duel so that the expectations
are set for "VPN on steroids" and perhaps the limitations are
identified if the results are too far from "on par".
(Just saying, not doing, I wouldn't go too far in tweaking
kronosnet for the best results possible, I'm afraid).
