Panic String: bpf_mcopy

erode · Nov 30, 2021, 3:56 PM

Good morning, a pleasure. We acquired two Lenovo "SR 250" servers, to which we installed pfsense 2.5.2-Release on FreeBSD 12.2-Stable. We are having once a day or every other day, a kernel panic that indicates: Panic String: bpf_mcopy

The equipment is only installed and we get to configure the lan, wan and sync plate (has carp). It is not in production yet, so it has no traffic or cpu / memory load.

I leave a detail of some hardware components that my server has:

ThinkSystem SR250
RAM: DDR4 16gb ecc
CPU: Intel (R) Xeon (R) E-2224 CPU @ 3.40GHz
Network cards: Broadcom NetXtreme PCIe 1Gb 4-Port RJ45 Ethernet Adapter PCI-E
Emulex VFA5.2 2x10 GbE SFP + PCIe Adapter

I also have the log of the dump, I leave it attached. I would appreciate if you could help me, since we have bought these servers and we cannot move forward with pfsense because of this kernel panic.dump_27_11_pfsense_up.txt

And they are all almost identical so it's almost certainly a software issue.

The msgbuf output doesn't show anything concerning. It is mostly panicking before logginh anything after bootup.

It looks like that's in the Emulex driver. That's not too surprising since it not commonly seen with pfSense.
Are you able to test it without the Emulex NICs in use to prove that?

@stephenw10 Thank you very much!! doing some tests on the aforementioned fiber board, I see that when enabling or disabling it the operating system hangs and there this error occurs.

I'm going to change the fiber board for another from a different brand, to see if that's what it is.

It is a problem for me since it is just the 10gb board, and the others I have are 1gb, and I need to have a 10gb interface.

Then I'll tell you how it went with the other network interface :)

stephenw10 · Dec 2, 2021, 3:08 PM

Ah, well if you are able to confirm it's the oce driver/hardware there may be a workaround. For example it looks like there have been some TSO issues with it in the past so I'd make sure that is disabled.

Steve

erode · Dec 2, 2021, 3:26 PM

@stephenw10 Thank you very much for your answer! Obviously it seems to be the board, because in another pfsense that we put as a backup to build the HA CARP, it gives us the same behavior (when activating / deactivating the board the server hangs, but it does not show dump).

How can I check if TSO is activated? O How could I deactivate TSO? I was reading that by default it is disabled.

Very kind, thanks again

stephenw10 · Dec 2, 2021, 3:43 PM

Yes, it should be disabled but the that NIC is quite complex. I expect it has a bunch of offload options.
Run ifconfig -vm against it. That will list the enabled options.

Steve

erode · Dec 15, 2021, 7:29 PM

@stephenw10 Thanks! The problem was fixed, apparently some initial installation or configuration issue, after the reinstallation we had no problems. But the problems were indeed caused by the 10 GB motherboard, luckily it did not have to be changed. Just reinstall. Thanks for the help.

Hello! how are you? Unfortunately we continue with this kernel panic, in this last month it appeared 3 times. We could not identify why it happens, since at the time of the crash we are not touching anything on the device.

We have two identical Lenovo sr250 computers, and it happens randomly on both of them. The only thing I could see is that the minute the crash occurs, the cpu consumption shoots up a lot.

I have the backtrace, but I don't really know how to read it. I leave it attached, could you give me an indication of where to start looking? we are about to go into production with this equipment to replace mikrotik, but now we are in serious trouble.

Did you try that yet? Did you disable hardware options?

Hi Steve, nice to talk to you again, thank you very much for your reply. I enclose the configurations that I have about what you tell me. if you see rare ips it is because I modified them for security

@erode said in Panic String: bpf_mcopy:

options=500b8<VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,VLAN_HWFILTER,VLAN_HWTSO>

Hmm, well you might try disabling the hardware VLAN off-loading options on oce1 there. The panic looks like it could be in one of them.

Do you see mbuf being used excessively? Check the Monitoring Graphs. It appears there have been issues in the driver previously.

This looks almost identical but no solution shown:

@stephenw10 Good morning Steve :) thanks for your time and your answer.
From what I can understand, according to the configuration I have, I already have off-loading disabled, am I right? look at this image:

We already had this enabled and we already restarted the computer several times with this option checked. The strange thing is that when doing the ifconfig -vm, it shows enabled on the 10 gb main board, and also on the vlans that are mounted on this board:

oce0: flags=8002<BROADCAST,MULTICAST> metric 0 mtu 1500
options=507bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,VLAN_HWFILTER,VLAN_HWTSO>
capabilities=507bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,VLAN_HWFILTER,VLAN_HWTSO>

(vlan:)

description: Solar
capabilities=703<RXCSUM,TXCSUM,TSO4,TSO6,LRO>

Sorry for the inconvenience, but from where else could I disable what you tell me? try doing it with: ifconfig oce1.250 -vlanhwtso -tso4 -tso -lro

but then when I run ifconfig -vm oce1.250 it still shows me the tso options, it doesn't change anything. Try to restart also after executing these commands by console, but I was not successful either, I still see them the same.

The question would be what would be the way to disable it? taking into account that I already have that option marked in the image that I showed you. Also, do you have any idea if the Emulex VFA5.2 2x10 GbE SFP + PCIe Adapter board supports pfsense? Is there a list of compatible motherboards so I can check?

Regarding what you tell me about mbuf, we have monitored the use with zabbix and it never reaches saturation. We have also raised the maximum value of mbuf to 1000000, and we also increased this value:

here we can see the use of the mbuf in the last 2 days, yesterday before 1 pm, the kernel panic occurred (a drop in the line is noted). but I understand that this would not be generating problems.

Steve, thank you very much in advance for your help.

stephenw10 · Feb 9, 2022, 4:53 PM

You still see those enabled on oce0 because it's not assigned and enabled in pfSense so no default settings are applied.

The vlans inherit their options from the parent interface so disable that vlan hardware offloading on oce1.

Steve

@stephenw10

Thanks again Steve! the oce1 network card (emulex) has the lan network assigned, then I have mounted the other vlans on oce1 as well, I show you the configuration:

It's strange that it's not assigned and it's not applying the changes, since I have the option "hardware tcp segmentation offloading" and "hardware lardge recieve offloading" checked several weeks ago, and the server has been restarted several times.
When you tell me to disable hardware download in oce1, where should I do it? Since I understand that this is done by checking the "hardware tcp segmentation offloading" option in system -> advanced, is there any other way to do it? Thank you very much Steve, sorry for the inconvenience

stephenw10 · Feb 9, 2022, 5:20 PM

oce0 is not assigned though which is what you showed above.

I would not expect to see TSO or LRO enabled on oce1 since it is assigned.

Steve

erode · Feb 9, 2022, 5:24 PM

@stephenw10 Thanks Steve, sorry for the confusion! oce0 is currently disabled as we don't have any cables connected to this board as we don't plan to use it. Should I enable it anyway? I understand that if the vlans are in oce1 they should inherit from there, or if I need to assign plates, this off-loading option is not applied? thanks again Steve!!

stephenw10 · Feb 9, 2022, 6:06 PM

It should be applied there but I can't see because you haven't posted the ifconfig output showing oce1.

erode · Feb 9, 2022, 6:36 PM

@stephenw10 Sorry Steve, I'm sending you here the complete result of ifconfig -vm (I had to hide the ips, in case you see 11.11.11.11 on all boards)
Thank you for all this help you are giving us!

I'm sorry you did actually post that already above.

But, that's what I expect to see. The TSO and LRO options are disabled already.

The VLAN hardware options are not though which is why I suggested disabling them manually as a test.
