IPv6/4.1.0 RC 4/Wired Ethernet

Post by k2dls » Thu Aug 29, 2019 11:02 pm

I'm having an odd issue on my Pi-Star 4.1.0 RC4 system which is using wired ethernet.

I'm not getting a global IP address from my IPv6 DHCP server on boot.

Aug 29 18:29:04 pi-star dhcpcd[211]: eth0: soliciting an IPv6 router
Aug 29 18:29:04 pi-star dhcpcd[211]: ipv6nd_startrs1: Address family not supported
Aug 29 18:29:04 pi-star dhcpcd[211]: ipv6nd_startrs1: Address family not supported

After the system is up, if I rerun dhcpcd (systemctl restart dhcpcd.service) I then get the expected IPv6 global address from DHCP.

Aug 29 18:58:30 pi-star systemd[1]: Started dhcpcd on all interfaces.
Aug 29 18:58:31 pi-star dhcpcd[1099]: eth0: ADV 2001:xxx:xxxx:x::34/128 from fe80::xxxx:xxxx:xxxx:xxxx
Aug 29 18:58:31 pi-star dhcpcd[1099]: eth0: accepted reconfigure key
Aug 29 18:58:31 pi-star dhcpcd[1099]: eth0: REPLY6 received from fe80::xxxx:xxxx:xxxx:xxxx
Aug 29 18:58:31 pi-star dhcpcd[1099]: eth0: adding address 2001:xxx:xxxx:x::34/128

Can someone else please replicate this (on a wired ethernet system)? I had it working just fine with the 4.0.0 RC4 build. I also have another wired ethernet system running Buster (an upgrade from Stretch) where IPv6 gets the proper address at bootup.

IPv6 was disabled. I had not checked sysctl, but was reminded by this:

However, makes me wonder then why IPv6 works just fine with wireless wpa_supplicent when turned off via sysctl. Perhaps it gets turned on dynamically later?
