Today I removed some netns with various virtual interfaces. In one of the netns there was a wireguard tunnel and it looks like it is still alive.

The peer gets handshakes while I cannot find the wg in any named netns. But the "lsns --type=net" shows three namespaces without a pid and without a mount… and I assume that there is a #FrankenGuard hiding in one of them. 🧟 🧟 🧟

Any idea how I could get into these anonymous netns to remove the wg interface?

…a ping to the management ip got a dest unreachable. 🤯

*WTF*

Need to crash it just another time to have a serial console logging ready: https://tpaste.us/VnYv

It initial happened on 6.18.33 with 1Gbps/140k pps forwarding traffic, but also on 6.18.35 with some lower throughput. 😭

The XDP program can be found at https://codeberg.org/routerkit/fragg-off - it might crash your machine 🤷

Last week I participated #SaltSprint to discuss declarative network configuration in #NixOS. I got the feedback, that replacing scripted networking with #ifstate of a full blown frr-based EVPN setup is possible and did just work. 💪

This feedback makes me really happy 🤗 #WorksAsIntended

In return, ifstate got a larger pull request improving its python packaging and CI tooling. And there is a commitment for further contributions. ❤️ ❤️ ❤️

2) IPv6 tokenized interface identifier support was added to allow to configure the IPv6 interface identifier for interfaces doing SLAAC: https://ifstate.net/schema/2.4/#interfaces_pattern1_token

This was specified in https://datatracker.ietf.org/doc/html/draft-chown-6man-tokenised-ipv6-identifiers-02 and is implemented in the Linux kernel. Ifstate provides the same functionality as the ip-token(8) command from iproute2.

The new release is already available in Alpine Linux edge and will be part of Alpine Linux 3.24 🥳

In case you bother why I'm looking at MAC address handling for various link types of the Linux kernel: I'm working on a new ifstate feature to get reproducible mac addresses for virtual interfaces and reset the mac address of physical links to their permanent mac address by default.

https://codeberg.org/routerkit/ifstate/pulls/185

The reproducible MAC addresses are based on SHAKE256 with an input build from the host (machine-id), netns and interface (link) name.

#TIL One could change the mac address of the lo interface, but one cannot revert it to 00:00:00:00:00:00. When the kernel boots or a netns is created, the lo interface spawns with the initial mac address 00:00:00:00:00:00. It can be changed afterwards, but it seems to be impossible to change it back to it's initial value 00:00:00:00:00:00. Fascinating. 🤷

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...

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. 😎
