@CruxtheNinth Do you use "Use IPv4 connectivity" for DHCPv6 in your WAN setup?

no, "use IPv4 connectivity" is disabled, i only ever enabled it once for testing after the 24.7.2 update when i misread the PPPoE/IPv6 Thread.

Ok, thanks for the additional info. To me it looks like a timer stuck and triggering increasingly often without the need for it. It's not directly related to the patch. I triple checked the code. So what likely happened is we uncovered a real bug now that would fix itself in the previous code version, maybe related to a SIGHUP event.

Uwe, wasn't there something about the dreaded IPv4 connectivity switch?

Yes, I had to switch that with 24.7.x. My working settings for the DG installations look like this. Note I use the new "IA-PD-only" scheme for DG and use one of the prefixes for the WAN interface, as I found early that DG does not answer at all if an IA-NA is requested. Maybe that is the problem?

Ok, I built a test version that gives us visibility over timer create/remove and current number of events:

https://github.com/opnsense/dhcp6c/commit/1e84486429

# pkg add -f https://pkg.opnsense.org/FreeBSD:14:amd64/snapshots/misc/dhcp6c-20240820_1.pkg

(please reboot at your convenience)

# opnsense-log | grep 'dhcp6c.*event'

opnsense-log only keeps the last day so when this fails tomorrow I gladly take the full logs as before.

It lists things from here and doesn't crash so I'm fairly confident this can help with finding the actual problem.

Ok, WTF, I can see that on my end as well already:

creating an event on igb1, state=INIT
removing an event on igb1, state=INIT
listing event on igb1, state=INIT
creating an event on igb1, state=INIT
removing an event on igb1, state=REQUEST
listing event on igb1, state=REQUEST
creating an event on igb1, state=RENEW
removing an event on igb1, state=RENEW
listing event on igb1, state=RENEW
creating an event on igb1, state=RENEW
removing an event on igb1, state=RENEW
listing event on igb1, state=RENEW
creating an event on igb1, state=RENEW
removing an event on igb1, state=RENEW
listing event on igb1, state=RENEW
creating an event on igb1, state=RENEW
creating an event on igb1, state=REBIND
listing event on igb1, state=RENEW
removing an event on igb1, state=REBIND
listing event on igb1, state=RENEW
listing event on igb1, state=REBIND

Same thing happened to me. Suddently IPv6 was lost on my DG installation and not coming back to life since 6 hours. I'll see if I can catch the logs requested.
August 27, 2024, 08:51:24 PM #22
I'm pretty sure the problem is somewhere here:

https://github.com/opnsense/dhcp6c/blob/abd51bd51ce0090a66dcec8aca0ef3c320490cbe/dhcp6c_ia.c#L577-L595

Maybe dhcp6_set_timer sets a zero time and the REBIND kicks in as well which isn't very helpful.

At least something to play with here.

Doesn't always break it seems, but looks like this is an interesting lead.

I only use the Prefix-Hint option and i receive both PD and /128 IA-NA on WAN

Hmm, this gets weirder:

reset interval is sec=0, usec=663000
reset interval is sec=0, usec=516000
reset interval is sec=1, usec=84000
reset interval is sec=1, usec=80000
reset interval is sec=10, usec=511000
reset interval is sec=429497, usec=672000
reset interval is sec=0, usec=734000
reset interval is sec=0, usec=994000
reset interval is sec=0, usec=571000
reset interval is sec=0, usec=380000
reset interval is sec=0, usec=367000
reset interval is sec=0, usec=122000
reset interval is sec=0, usec=284000
reset interval is sec=1, usec=58000
reset interval is sec=1, usec=48000

I suspect https://github.com/opnsense/dhcp6c/commit/fe3ed661a5 is partly to blame here but the modifications look correct to me. There must be an edge case in there we've uncovered.

EDIT: Appears to be RELEASE specific issue, possibly not new and irrelevant.

Hi,

I still don't get an IPv6 from DG. Don't know if this is an DG issue or related to the problem discussed here.

I did the following:

opnsense-revert -r 24.7.1 dhcp6c
opnsense-update -zkr 24.7.2-nd

But nothing changed for hours so I reverted to to 24.7.2 original state.

I installed

# pkg add -f https://pkg.opnsense.org/FreeBSD:14:amd64/snapshots/misc/dhcp6c-20240820_1.pkg

and rebooted. But I don't see any 'dhcp6c.*event' messages (I enabled DHCPv6 logging on INFO).

I only see the following messages for dhcpv6:

It's not very assuring.

Ok Franco I disabled the PPP device. This was also requesting an IPv6 for no reason. Output looks ok now for my limited knowledge. But nothing happens ...

    No more output since last line. Can you spot anything relevant or is this just an DG issue and waiting should help  ;)
August 29, 2024, 12:51:50 PM #29
why do you need PPP for DG? That should not longer be necessary according to their own published specs.
Both IPv4 and IPv6 should do DHCP (via IPOE)

Are you mistaking DG with Deutsche GigaNetz? DG in this thread is Deutsche Glasfaser, not Deutsche Giganetz.

Ok Franco I disabled the PPP device. This was also requesting an IPv6 for no reason. Output looks ok now for my limited knowledge. But nothing happens ...
