kronosnet v1.13 released
by Fabio M. Di Nitto 16 Oct '19

16 Oct '19

All, We are pleased to announce the general availability of kronosnet v1.13 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: * IMPORTANT/URGENT: fix defrag buffer reclaim logic that could lead knet to deliver corrupted data to the application (corosync or alike). * IMPORTANT/URGENT: fix MTU boundary check on links with very high packet loss and avoid delivering corrupted (short) data to the application. * Optimize reassembly of defrag packets by avoid unnecessary memmoves. * Improvements to the test suite to deal with the above bugs and potentially reduce regressions in future. * Minor stability fixes to the test suite. 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 v1.12 released
by Fabio M. Di Nitto 20 Sep '19

20 Sep '19

All, We are pleased to announce the general availability of kronosnet v1.12 (bug fix release) 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: * IMPORTANT: any version prior to 1.12 has a memory corruption bug that could cause knet to crash or hung when the network is not stable for a long period of time. Please see https://github.com/kronosnet/kronosnet/issues/255 for details. If you are unable to upgrade to 1.12, please make sure to cherry pick https://github.com/kronosnet/kronosnet/commit/6a92361c7554c2aa7222d6f868e43… (stable branch) into your distribution as soon as possible. * Fixed all coverity scan errors for runtime code. * Fixed latency calculation in some corner cases that could cause internal latency values to spike too high with incorrect values. * Fixed some documentation. * Add support for musl libc 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 v1.11 released
by Fabio M. Di Nitto 21 Aug '19

21 Aug '19

All, 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 soname bump) * Minor internal improvements and bug fixes. 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
