It was a pointer! I knew it! Nice find @theMIROn .

It appears Merlin firmware may have strace compiled in with it. This would be some great log output to obtain on the issue: With stateful enabled, simply: killall dnsmasq & strace -fivyo /tmp/trace.log dnsmasq --conf-file=/etc/dnsmasq.conf When done, results will be in /tmp/trace.log . If you...

I completely agree with your assessment of the issue. I mentioned on the previous page of this thread that the alignment fault is likely the cause, dnsmasq crashing being a symptom. I've been hunting through the github fishing for changes that include both IPv6 code and things like buffers...

@john9527 , would you consider this correct? if (inet_ntop(AF_INET6, &addr, buf, sizeof(buf))) { strlcat(buf, "/64", sizeof(buf)); eval("ip", "-6", "addr", "add", buf, "dev", (char *) ifname, "scope", "link"); } A change to IPv6 code, committed here . It adds the /64 prefix...

I'm not sure about the nomenclature used for the options in Merlins firmware, so this is a craps shoot, but try setting the DHCP-PD option to disabled, enable stateful, reboot router and check the logs. Reasoning: In Tomato firmware, the equivalent "type" option that works for Comcast is...

Changes made to forward.c, in this commit, are in the area of suspect. Just based on code location/function/timeline .. it's Sunday night - brain won't parse detailed code inspection.

Are you by chance running entware-ng, or something of the sort for opt? If strace is available, an output from it running dnsmasq in stateful config would be great to check.

Dogs get destructive when left alone, first one just needed a buddy :confused: . Though I would have figured the watchdog watching the watchdog would have been one in hardware, not both in software. Watchdogs aside, looking into that kernel fault I came across this in the ARM community forums...

@RMerlin , is this a one-off issue to your knowledge? Or have you had reports of/come across this issue with stateful LAN IPv6 from other users?

Hah, just like it says right at the bottom of all your posts. Yikes, sometimes my ADD gets the best of me. I'll continue researching the issue in relation to Merlins code and see what I can find.

What specific router are you using? I apologize if you already stated previously.

Correct, but the kernel fault would not be a part of the cycles I explained.

Good suggestion. However, I'm very much leaning toward dnsmasqs issue being a symptom not a cause. Especially with the alignment fault directly following. A dnsmasq configuration issue ( such as the implied lack of upstream servers ) should result in, at minimum: a log entry warning followed by...

Ok, then we're barking up the wrong tree. The issue dnsmasq is having is a symptom not a cause. You stated you're on Comcast.. when stateful is enabled, run: ifconfig vlan2 & ifconfig br0 Providing vlan2 is the default WAN interface in Merlin firmware. Does vlan2 have an IPv6 address starting...

Was this log entry created after a successful dnsmasq start using command line with the /tmp/dnsmasq.conf file?
