Reproducible kernel panic with pfSense 2.2 and IPSEC
-
I'm not sure this is 100% reproducible, but I have seen this numerous times in the last couple of days. Had to downgrade some production boxes to 2.1.5 because they kept randomly crashing at least once a day.
These are also Alix 2D13 boxes. I cannot make them crash at will by any means I know about, but they do crash. Particularly in the early morning when traffic on the IPsec tunnels is reestablished after idling during the night, so I believe it is also IPsec related.
ermal, could you elaborate on the time source issue??
-
For example
kern.timecounter.hardware: TSC-low
kern.timecounter.choice: TSC-low(1000) ACPI-fast(900) i8254(0) HPET(950) dummy(-1000000) -
Alright, I grabbed one Alix box and changed:
kern.timecounter.hardware: TSC -> i8254Will report back if this box keeps coredumping.
It'd be great if sh0gun could test this on his reproducible scenario
EDIT: In case it is not clear, to temporarily set the value you can run "sysctl kern.timecounter.hardware=i8254" on the shell, or force the tunable through the advanced options. Anyway, no idea about this setting
-
I'm having the same issue, in my case it crashes when I keep IP compression enabled in the advanced IPsec options. Try disabling it if enabled, maybe it helps in your case too.
I have a reproducible kernel panic with pfSense 2.2 and IPSEC.
My setup: ALIX 2D13, IPSEC with one P1. IKEv1, PSK, aggressive. One P2 (net-to-net tunnel). pfSense must be the responder upon P2 connection. Now send a ping from any host in the remote network to the local pfSense box -> immediate crash.

I can not use IPSEC unfortunately. IKEv2 is not an option because there are compatibility issues with the opposite side. And: sorry for my english... [/thread] -
My system is D2500CC mini-ITX motherboard from Intel, all embedded into it.
I have configured WAN as PPPoE and LAN as 10.0.x.x
I have also configured IPsec for mobile clients using this "guide" https://forum.pfsense.org/index.php?topic=87655.msg488294#msg488294
Virtual IP network for mobile clients is configured as 10.0.y.y
When I get the successful connection it looks like traffic is not moving at all between client and firewall. Mostly it crashes with this panicFatal double fault:
eip = 0xc0cd225f
esp = 0xe0783fe8
ebp = 0xe0784050
cpuid = 1; apic id = 01
panic: double fault
cpuid = 1

Currently disabled IP Random id generation (Insert a stronger id into IP header of packets passing through the filter.)
Testing… -
So far so good… no problems currently with IPSEC uptime and panics. Using Stronswan android client 12 hours already.
Previous record was 1 minute with IP Random id generation enabled -
@ermal:
For example
kern.timecounter.hardware: TSC-low
kern.timecounter.choice: TSC-low(1000) ACPI-fast(900) i8254(0) HPET(950) dummy(-1000000)On my ALIX board I have the choice between the following time sources: TSC(800) i8254(0) dummy(-1000000)
Changing the timesource with
sysctl kern.timecounter.hardware=i8254 kern.timecounter.hardware: TSC -> i8254does not have an effect on this issue. After changing the timesource IPSEC keeps crashing on first ping from remote.
Here are the latest dump with timesource i8254:

And you don't have "IP Random id generation" enabled?

@w0w:
And you don't have "IP Random id generation" enabled?
"IP Random id generation" is off. This setting I have never changed. Otherwise, I have only MSS clamping enabled and the Unity plugin disabled. "IPsec Mobile Client Support" is also turned off. All other settings are defaults.
Apparently the kernel timesource is not the cause of the error. Could someone have another look at the dump? What information is still needed?
-
We need to use bugtracker to report the bug. Please report this issue here https://redmine.pfsense.org/
Don't link the forum page, post your dumps and I'll add mine too.
FYI I don't have changed MSS and unity settings. -

Similar issue here. If I connect via VPN, PFSense stops and restarts - the IPSEC connection lasts between 30 seconds and 5 minutes. This issue is 100% reproducible - I've crashed my box about six times today.

@afasoas: are you running 32 or 64 bit version? So far I think all the reports are coming from x86 versions. Is this reproducible under x64??
-
32 bit.
Well spotted.
I will add my crash dump to the bug tracker shortly. -
Upgraded my hardware so I could run the 64-bit version. No issues to report thus far. IPSEC seems solid and stable.
-
Great solution, but this is like cutting the head and sewing back a new one, more "brainful".
It could be also driver Ethernet issue with physical low memory installed. I can only wait when somebody really smart will check our crash dumps to find out the reason of double triple crash and panic. -

I can only wait when somebody really smart will check our crash dumps to find out the reason of double triple crash and panic.I appreciate that this isn't the most helpful solution. I just wanted to confirm that the problem went away using the same configuration with a 64-bit version.
On Edit: I realise that you are using an Atom D2500 - you can run the 64-bit version of pfSense on it, if that helps?
-
I can, really, but what if I don't need it? My typical memory usage is less then 6% and CPU is mostly 90% in peak (300Mbit internet, three clients). I can buy some XEON based proliant G8 but why? :)
Maybe I'll move to x64 platform if we can't trust x86 anymore. But I need an answer for the question. DO we really need to move to x64 just because x86 is not supported or what?
I think i'll wait for answer before buying some needless hardware. :) -
And what about the ALIX boards? As far as I know they are all 32bit.
