Crash report!!!!

[Antibiotic]

@the-other Yes. I know these settings. Just want to warning about crash status!

Hmm, backtrace is unusually long:

Seems to be unrelated to the hardware offload settings.

Also happened twice, did you do anything else that may have triggered it?

The backtrace is in OpenVPN and looks to be in IIMB. I assume you have that enabled? With OpenVPN DCO?

I switched ON than OFF
Second question , yes ( openvpn with dco and iimb)

[Antibiotic]

@stephenw10 Again crash report, but now after changing settings in limiters!

textdump.tar (1).0 info (1).0

Idk, what is going on!

So that's a completely different panic.
What exactly did you change?

[Antibiotic]

@stephenw10 Limiters settings

[stephenw10]

Right but what did you actually change? Added the limiter entirely?

[Antibiotic]

@stephenw10 Changed limits and flows figures

[stephenw10]

Hmm, was anything logged? Any alert shown other than the crash?

Did it crash immediately when you saved those changes?

[Antibiotic]

@stephenw10 '

1. None
2. None
3. Yes

[stephenw10]

Hmm, it is repeatable?

We'd need to replicate it locally to dig further so steps to reproduce would help a lot.

[Antibiotic]

@stephenw10 Idk, will it help, that what I found i sys.log. That was on next reboot after crash

I think will remove Limiters as full of bugs

[Antibiotic]

@stephenw10 said in Crash report!!!!:

further so steps to reproduce would help a lot

Steps , what I did
Untick all offloads (Limiters were already) , than switch off back all offloads get first crash. After reboot changed some settings in Limiters as above in my post, get second crash. Next step remove Limiters and waiting now third crash.

[stephenw10]

And just resaving the Limiters again did not reproduce the crash?

[Antibiotic]

@stephenw10 Sorry, already removed Limiters and making state resetting's

[kprovost]

@stephenw10 said in Crash report!!!!:

Hmm, backtrace is unusually long

It's a routing loop. The OpenVPN traffic is being routing into the OpenVPN tunnel. Sooner or later we run out of stack and crash.

It's a bug in if_ovpn that it doesn't discard this traffic, but it's also a configuration error. Once the bug is fixed the tunnel still won't work.

[Antibiotic]

@kprovost said in Crash report!!!!:

but it's also a configuration error.

What do you mean, in my configuration error? Or OpenVPN have error itself?

[kprovost]

@Antibiotic You've somehow configured your system so that the OpenVPN tunnelled traffic goes down the OpenVPN tunnel.

[stephenw10]

Check the routing table in Diag > Routes. Is your default route getting set to the OpenVPN gateway?

Make sure the system default gateway is set to the WAN gateway in Sys > Routing > Gateways.

[Antibiotic]

@stephenw10 That , what I have . Is this incorrect?
