@me:m4rc3l.deMarcel * and some coperate VPNs 19:48:02
@tom:dragar.deTomFreifunk Karlsuhe seems to have rolled out IPv6 mostly at the end of last year https://chaos.social/@ffka (German) It would probably make sense to talk to them at some point. But it makes me kinda hopeful that the Apple weirdness i observed in 2024 has disappeared enough (by patches and people constantly upgrading their devices) that it becomes viable at some point. But i think my Pixel 8a with current Graphene OS still has the issue that the network stack sometimes becomes unresponsive and only a reboot fixes if it's in a ipv6 mostly enviroment.20:15:30
@tom:dragar.deTomyeah, it seems to be working for me with 1.57.2-dev21:41:14
@tom:dragar.deTom But looking at tcpdump it doesn't seem like you can even easily tell (if at all) it's a networkmanager dhcp request. So matching based on version seems even more out of the question.
(You could ofc set ipv4.dhcp-vendor-class-identifier but that doesn't seem scalable)

@antifuchs:asf.computerantifuchshah, so I have just learned that nixos-nftables-firewall is pretty suboptimal in terms of performance01:49:39
@antifuchs:asf.computerantifuchsa machine that handles 10Gb/s of traffic easily will struggle with this zone config that I applied to it just now (about 170 handles)01:51:06

@antifuchs:asf.computerantifuchs so, somewhat serious question though, I don't think boot.kernel.sysfs.class.net.eno8np0.device.sriov_numvfs = 32; is working; the path never triggers, even though the file exists. when I manually start the service, it applies the setting; is that boot.kernel.sysfs handling broken somehow, or am I expecting it to do something impossible? 23:35:29

@sandro:supersandro.deSandro 🐧I had before that I needed to manually load a kernel module early on (as in with the option for it) to make the sysfs paths available when the sysfs service starts13:02:08
@antifuchs:asf.computerantifuchshuh, do you remember what kernel module that is?16:29:16
