Hello Ondrej,

Did you have a chance to check out the patch? I am happy to adjust it if
needed.

Hello

Thanks for a notice, i just merged that (with minor modification):

https://gitlab.nic.cz/labs/bird/-/commit/d61505b039bf0aa6697e28b2a4e07907c89ba1fb

I didn't test the feature, as our FreeBSD VM is still at 13.0
(bsd-cloud-image.org does not offer never version), but it seems safe.


FreeBSD project provides us with official Cloud-init-like images for testing purposes[1]. These images really cannot be provisioned with Cloud-init, but you will be able to log in via ssh on your root account (neither key nor password is required), which should be sufficient. FreeBSD 13.2-RELEASE is the first release with netlink(4) support. Netlink is available as a kernel module and needs to be explicitly loaded.

BTW the Netlink flavour of BIRD 2.0.12 under FreeBSD runs smoothly. We are running it for over two months. Resident memory usage dropped in our case from 2G to less than 512M. ECMP works out of the box. The daemon complains about slow scans of the kernel routing table[2] though, but it's not a problem. Many thanks to the people who contributed to this !
