All, We are pleased to announce the general availability of kronosnet v1.9 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. Highlights in this release: * Reduce minimum crypto key size requirement to 1024bit * Drop libnss 3des support * Lots of man pages improvements and cleanup * Improved UDP error reporting from ICMP error messages Known issues in this release: * none The source tarballs can be downloaded here: https://www.kronosnet.org/releases/ Upstream resources and contacts: https://kronosnet.org/ https://github.com/kronosnet/kronosnet/ https://ci.kronosnet.org/ https://trello.com/kronosnet (TODO list and activities tracking) https://goo.gl/9ZvkLS (google shared drive with presentations and diagrams) IRC: #kronosnet on Freenode https://lists.kronosnet.org/mailman/listinfo/users https://lists.kronosnet.org/mailman/listinfo/devel https://lists.kronosnet.org/mailman/listinfo/commits Cheers, The knet developer team

kronosnet v1.8 released

by Fabio M. Di Nitto

All, We are pleased to announce the general availability of kronosnet v1.8 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. Highlights in this release: * Fixed SCTP transport on FreeBSD. * Fixed a potential use-after-free that could lead to a crash when unconfiguring links at runtime. * Fixed a link configuration error that would allow a user to configure, for example, an IPv4 source address and an IPv6 causing knet to spin at 100% of the CPU. * Minor man pages fixes and improvements. * Minor build and test suite fixes. * Minor logging events fixes. Known issues in this release: * none.

Highlights in this release: * Fix minor issues with libnozzle man pages * SCTP: support more kernel versions * Better debugging information of internal threads status * Fix build with gcc9 * [developers] expose API version in libknet.h and enable all compiler warnings at build time Known issues in this release: * libnozzle needs better porting to FreeBSD (even tho it works as-is).

How does kronosnet relate to/compare with Transparent Inter Process Communication (TIPC)

by Jan Pokorný

Hello list, sometimes, usually when surfing semi-randomly, I get to know about things that either resemble deja vu to me, or make me feel that I must have lived in an utter ignorance/tunnel so far. Now, both thing combined: https://en.wikipedia.org/wiki/Transparent_Inter-process_Communication Especially now that I checked the kernel module and userspace utility lurk on my Linux machine without ever being asked :-) $ { eval modinfo\ {-F\ description\ ,-F\ version\ ,-F\ license\ }tipc\; echo; tipc -h; } > TIPC: Transparent Inter Process Communication > 2.0.0 > Dual BSD/GPL > > Transparent Inter-Process Communication Protocol > Usage: tipc [OPTIONS] COMMAND [ARGS] ... > > Options: > -h, --help Print help for last given command > > Commands: > bearer - Show or modify bearers > link - Show or modify links > media - Show or modify media > nametable - Show nametable > node - Show or modify node related parameters > peer - Peer related operations > socket - Show sockets Naturally, I am curious how much of an overlap is there, wether there have been any comparisons/benchmarks conducted, all the these sort of things incl. whether the was an a priori knowledge, perhaps inspirational, about this other project. Kronosnet looks to me more on the pragmatically usable and simple side, buying also better portability and avoiding complexities (I take the plugins more like a "look what we can offload from your application layer" demonstration, yet encryption/auth/integrity protection makes a great deal of sense there) beyond UDP (which fully suffices when combined with corosync), something that TIPC covers as well while providing a lot of other abstractions incl. peer discovery, bells and unicorns (which might be heavy overkill for that use case). Any inputs welcome. -- Jan (Poki)
