That's strange. Wasn't net-tools deprecated in favor of iproute2? It should at least cover every use case. |
|
|
It works for me: the service is restarted when switching configuration.
Thanks. I'll try to adapt those changes to the new network-interfaces. |

I have tested IPv4/6 addresses/routes. Everything is working except the stop script fails to remove IPv4 routes for some reason. |

I'm trying to write a test but I know exactly zero about perl. import src/nixpkgs/nixos/tests/make-test.nix
{
name = "routes";
machine = {
networking.useDHCP = false;
networking.interfaces."eth0" = {
ip4 = [ { address = "192.168.1.2"; prefixLength = 24; } ];
ip6 = [ { address = "2001:1470:fffd:2097::"; prefixLength = 64; } ];
ipv6Routes = [
{ address = "fdfd:b3f0::"; prefixLength = 48; }
{ address = "2001:1470:fffd:2098::"; prefixLength = 64; nextHop = "fdfd:b3f0::1"; }
];
ipv4Routes = [
{ address = "10.0.0.0"; prefixLength = 16; }
{ address = "192.168.2.0"; prefixLength = 24; nextHop = "192.168.1.1"; }
];
};
virtualisation.vlans = [ ];
};
testScript = ''
my $ipv4Table = <<'END';
10.0.0.0/16 scope link

my $ipv6Table = <<'END';

END
$machine->start;
$machine->waitForUnit("network.target");
$machine->succeed("ip -4 route list dev eth0 | head -n3") eq "$ipv4Table";
$machine->succeed("ip -6 route list dev eth0 | head -n3") eq "$ipv6Table";

}How do I make an assertion? |

Thank you. |

I prefer this way because it's consistent with |

I think it's complete now. |

Looks good in principle, but I think we need some more options on the top level that can't be added with options. For instance, I use other types than unicast routes quite often. I'll push some more code for options into your branch shortly.

Calling this option nextHop is IMHO a bit misleading because there is a nexthop option in ip route that is used for multipath routes yet this option only sets via.

Do you recall why this is necessary? It should be fine but just interested. :)

Ah, I meant the bringing up as a whole but didn't see that this was removed from the addresses service. This is fine! 👍

I don't really like the extra v in ipv[46]Routes because the address options are just named ip[46]. Even without the v, the interface looks inconsistent to me because it is not clear that ip[46] is only for configuring addresses. No better idea how we should structure the interfaceOpts either.

So, what about ip{4,6}.{routes,addresses}?

I think it would be more appropriate to use an attrset of strings here. That also makes it more easily to override.

I'm wondering if we also need global routes that are not bound to interfaces. For instance, I'm adding unreachable routes to RFC1918 subnets on my routers to no traffic to them except explicitly defined via the default gateway (which is always an ISP in my case). |

Just want to express my thanks for your continuous effort of rebasing this. |

Thank you, also thank you for trying to get the maintainers' attention on this. |

Observations: and old PR, useful cleanup, looks fine to me, unchanged tests still pass, no objections even though multiple people have read the code, enthusiastic support from @oxij , commit logs in the relevant directory do not make me want to mention someone… |
|
Whooohoo! **Happy dance** Thanks to everyone involved!
|

Hopefully it's not hard to fix, but this breaks NixOS configurations using virtualbox, giving error: @GrahamcOfBorg test virtualbox.headless |

}fix it? |

See #35185. |

Thank you for the fix. |

I don't know... maybe retrying a few times with a loop before giving up?
Seems ok as a workaround to me.
But I think this needs to be reported upstream.
@volth Did you report this upstream yet?
