https://codeberg.org/routerkit/ifstate/releases/tag/2.2.5

The 76th release includes various fixes & improvements like:
- fixing address scope handling
- fixing non-wireless interfaces handled as wireless interfaces when moving them between netns
- make parsing route table files more compatible to iproute2

I am very grateful for the growing number of contributors. 🙏

Okay, this is weird.

I am seeing `tailscaled` spiking up to 250% CPU usage every other minute, with up to 60 MBit/s outgoing traffic on the `tailscale0` interface... and on the `wg0` interface I see the same amount of traffic during that period.

I now disabled wireguard and the issue is gone.

But I have absolutely NO idea why this is happening, what causes it, and why it (seemingly) suddenly started - I did not have this issue earlier today. All I did in between was update the unstable channel, but all packages involved here (tailscale, wireguard) are from stable. So... 🤔 I am at loss...

Unser @dd_ix Workshop zum Thema BGP Routing wurde auf den @clt_news angenommen 💪 . Für alle die meine Vorträge der letzten Jahre über Alpine Linux, ifstate oder Linux Router interessant fanden bietet sich hier die Möglichkeit für praktische Erfahrungen und Austausch.

ifstate 2.2.4 - a tool for declarative network configuration for Linux - was released:
https://codeberg.org/liske/ifstate/releases/tag/2.2.4

The 75th release includes various fixes & improvements like:
- make stable-privacy IPv6 addresses work
- resolve wireguard endpoints *after* configuring the network stack so that DNS resolution could work

This is the first release with published Debian packages: https://ifstate.net/2.2/docs/install/#debian-gnulinux

The ifstate git repository on #Codeberg has been moved from my personal account into the RouterKit project at https://codeberg.org/routerkit/ifstate

With moving the project it gains access to CI/CD runners and the first step is to use them to provide #Debian packages from the upcoming 2.2.4 release 🥳

I already use it in prod for haproxy setups on Debian trixie using different network namespaces for listeners and server access.

I don't like to maintain packaging upstream, but… I required netns configuration support on Debian for using network namespaces with haproxy!

Sadly I had to use dh_virtualenv because pyroute2 in Debian sid+stable is to old to have all required netns related features.

Haproxy has namespace support for listeners and servers which allows one to easily build multi-tenant load-balancing setups. 😎
