dhcpcd 9.4.1 requests DHCPv6 info every 10 seconds

[LW-archlinux]

Archlinux, systemd , wired connection

Gateway Router is a AVM Fritz!Box 7590 , software version 7.29 .
My ISP provides full dual stack IPv6 IPv4 addresses.

Since installing dhcpcd 9.4.1-1 on archlinux dhcpcd requests DHCPv6 information every 10 seconds.

Starting dhcpcd through dhcpcd.service or dhcpcd@enp4s0.service doesn't change this.

I'm encountering the same issue. Maybe this is related to 3b1f557 ?

I'm still receiving these!

[borkra]

Is it the case of router advertisements misconfigured? They say to use DHCPv6 but it's nowhere to be found. The other thing check timeout on leased IPs from DHCPv6.

And BTW, the issue is likely your router not ISP, IPv6 configuration messaging is using link-local IPs.

[Anachron]

I've disabled this via https://man.archlinux.org/man/core/dhcpcd/dhcpcd.conf.5.en#noipv6rs for now.
Everything else still works as expected.

This is exactly the case. I've committed a fix so that when debug is not enabled then only the first failure is logged.

Hey @rsmarples thank you for the fix!
Hopefully the next release wont take too long so I can remove my config option and have a clean setup.
