Host does not acquire DHCPv6 lease

[GoetzGoerisch]

Follow-up to: openwrt/openwrt#21350 (comment)

• Host (PS5) sends REQUEST
• Router sends REPLY
• Host sends SOLICIT and REQUEST again

@brunoab133

Please capture the DHCPv6 exchange between the router and the PS5:

tcpdump -i br-lan.10 -n -vv 'udp port 546 or udp port 547'

Thank you for the log.
Is this after a reboot of the PS5 and the router?
If not, please do so.

@systemcrash do you see anything obvious?

[brunoab133]

I restarted everything with all other clients turned off, leaving only the following devices connected:

Windows PC with IPv6 disabled
Switch without IPv6 support (TL-SG108E 4.0)
Only the PS5 on the network with IPv6 support

I ran tcpdump -i br-lan.10 -n -vv 'udp port 546 or udp port 547' and only after 1 minute did I turn on the PS5.

I don't see much difference, aside from the server uuid in 24.10 and DUID in 25.12. Can you use Wireshark (sshdump plugin) and grab a working 24.10 and problematic 25.12 capture? You can send them to my commit email. Look at any recent commit in this repo.

Or edit the respective posts after doing a -vvX for 24.10 and 25.12 tcpdumps. The -X should show hex so I can piece together what's happening: tcpdump -i br-lan.10 -n -vvX 'udp port 546 or udp port 547 or icmp6[icmp6type]=134 or icmp6[icmp6type]=133'

Ideally, restart networking, start capture, and plug the PS5 in. I want to see what happens from start to finish, including ICMPv6, and accompanying verbose logs (7) from odhcpd.

[systemcrash]

Please also show your dhcp config for both versions.

[brunoab133]

I haven't changed anything at all between 24.x and 25.x, I only switch versions by updating normally between 24.10 and 24.10 RC1.

I decided to simplify things for everyone, so I reset everything to default.

On the EdgeRouter X, I only configured the WAN to use PPPoE and added a username and password.

The problem persists; in version 24.10 the PS5 has IPv6; in 25.12 the PS5 does not have IPv6.

I already used the snapshot; depending on the odhcpd version, the PS5 either had IPv6 or not; but at the time I didn't have time to test anything or report it here.
On lan10 the PS5 does not have IPv6, on lan20 it does.

In openwrt 24.x the PS5 has IPv6 on lan10.

If you want any configuration for testing, feel free to configure it and post it here.

Here's the configuration I use, preserved between 24.x and 25.x.

ESorry for any problems here, and I'll clarify any issues. It's my second-to-last day of vacation, it's 2:02 AM here, and I drank 4 liters of IPA beer. Goodnight everyone, I'm going to sleep.

@Alphix - After a stare and compare - I'm stumped. The only difference I see is 24.10 - MAC, 25.12 - DUID. PS5 cannot handle DUID :D

24.10:

    Server Identifier
        Option: Server Identifier (2)
        Length: 10
        DUID: 0003000118e829ae5d43
        DUID Type: link-layer address (3)
        Hardware type: Ethernet (1)
        Link-layer address: 18:e8:29:ae:5d:43
        Link-layer address (Ethernet): Ubiquiti_ae:5d:43 (18:e8:29:ae:5d:43)

25.12:

    Server Identifier
        Option: Server Identifier (2)
        Length: 18
        DUID: 000470a805d868f145368a3a56715120c2b2
        DUID Type: Universally Unique IDentifier (UUID) (4)
        UUID: 70a805d868f145368a3a56715120c2b2

@brunoab133 Did you reboot the PS5 after you upgraded wrt? I don't know what you need to do to it - but perhaps try turning off IPv6 altogether on it - upgrade wrt then turn IPv6 back on.

[brunoab133]

PS5 turned off before testing, I used tcpdump and logread and only then turned the PS5 on.

I left the PS5 idle for about 5 minutes after turning it on, enough time for tcpdump and logread to stop generating results, and then I went to network and "test connection," when the PS5 tries to renew all IPs (I think).

There's a boot and a connection test done on the PS5 in the logs :)

What I know besides that is that the PS5 doesn't support IPv6-only networks and that the PS5 operating system is based on FreeBSD.

[Alphix]

@brunoab133 If you set the DUID manually on 25.12 to a DUID-LL type, does the PS5 work?

I.e. change /etc/config/network so that it reads:

config globals 'globals'
        ...
	option dhcp_default_duid '0003000118e829ae5d43'
        ...

(Apologies if someone has already suggested it, have a bunch of github issues to go through)
