Kernel panics after upgrade to R1

[danderson]

Just happened on RC2.  Fresh install via image and restored config.

i have an IPV6 rule that was forwarding to a remote IPV6 address, as soon as i disabled that rule it seems to have stopped crashing.

[franco]

@danderson Looking for a core dump using the debug kernel for this if you can help out as well.


Thanks,
Franco

[danderson]

@franco

ok, i installed the debug kernel and then rebooted, then enabled my ipv6 forward rule and made it crash.  i see /var/crash/kernel.0:
File too big to process. It will not be submitted automatically. in the crash report, what file(s) do you want me to grab?

Ill put them on my onedrive and shoot you a link at franco@opnsense.org if i remember correctly.

[franco]

Yes, email is correct. Only need the kernel.0, splendid! :)

[danderson]

email with link sent.

[csutcliff]

had my first crash with rc2 (debug kernel), submitted the report and put a link to the kernel.0 in the notes.

[newsense]

10+ hours uptime on r2 here, on all FWs.

[franco]

It was pretty late, kernel.0 is the wrong file... need the vmcore.0 instead. Sorry.


Cheers,
Franco

[danderson]

@franco

vmcore.0 file shared via link in your inbox now.

[franco]

So danderson's report was about https://github.com/opnsense/src/commit/9cb6d71f6a

There maybe one more, but it would be easier to base work on this on a new kernel build on Monday which incorporates the above commit.


Cheers,
Franco

[franco]

@danderson @csutcliff and anybody else who would like to help:

# opnsense-update -zkr 24.7.r2_2


Cheers,
Franco

[Seimus]

@danderson @csutcliff and anybody else who would like to help:

# opnsense-update -zkr 24.7.r2_2


Cheers,
Franco

Even if this is not much of worth (as the crashes were so far on Baremetal only), I am running this on a VM OPNsense. So far all good.

[newsense]

I have it running on 2 FWs, so far so good.

Can't test on the others as I lost access there due to a Zerotier issue that seems to have been introduced in RC1/RC2 - sent you an email about it.

[danderson]

@franco

updated kernel and rebooted, did the same steps previously done to cause a crash and no crash this time. I'll keep running this kernel for the day unless you want us to try the 24.7.r2_3 kernel.

@danderson @csutcliff and anybody else who would like to help:

# opnsense-update -zkr 24.7.r2_2

Franco
