eth0: hw csum failure

[ralphrmartin]

Is this the right place for my bug report? I believe so

Describe the bug I am Running Linux services 5.10.11-v7l+ #1399 SMP Thu Jan 28 12:09:48 GMT 2021 armv7l on 2 different raspberry Pi 4s, my syslog is rapidly filling up with messages containing

As this is happening on 2 different machines, it seems unlikely this is a real hardware failure, and indeed, networking seems to be working OK on these machines. The logs are rapidly filling with many GB of such messages, which is hardly helpful, either.

*To reproduce This started within the last month since doing an apt full-upgrade. Otherwise the 2 machines are running a variety of services quite unrelated to each other, so it seems doing any networking causes the problem

Bothe machines are connected to a Unifi switch, powered by PoE with an official PoE hat.

Expected behaviour Networking should not be generating spurious(?) hw error messages.

Actual behaviour See above. Further details of syslog contents can be provided on request

System Copy and paste the results of the raspinfo command in to this section. Alternatively, copy and paste a pastebin link, or add answers to the following questions:

Additional context Seems to have arisen in the last month's updates. I noticed the enormous log file sizes doing a monthly backup, and the log file sizes were as expected last month

As this hasn't been reported by anyone else (that I'm aware of), is there anything odd about your networking setup? Do you have any VLANs configured? Or a custom MTU defined on the interface? Unusual TCP options? IPv6 running? Multicast traffic?

The dump is kicked up off https://elixir.bootlin.com/linux/latest/source/net/core/dev.c#L3413

sk family=2 type=1 proto=6 sk family 2 is AF_INET (aka IPv4) type 1 is SOCK_STREAM proto 6 is IPPROTO_TCP TCP over IPv4 is used everywhere, so it can't be a generic bug with it.

The error message is rate limited, but what is the rate that these events are being logged at?

[ralphrmartin]

No VLANS, No custom MTU, No special TCP options. IPV6 is in use, No multicast traffic. In short, nothing unusual at all.

Apart from setting a hostname, my dhcpcd.conf file only has

clientid
persistent
option rapid_commit
option domain_name_servers, domain_name, domain_search, host_name
option classless_static_routes
option ntp_servers
option interface_mtu
require dhcp_server_identifier

static domain_name_servers=192.168.1.102 1.1.1.1 8.8.8.8
noarp
denyinterfaces wlan0

The errors are happening at a tremendous rate, many times every second. I've got 600MB of error messages in my syslog since resetting it perhaps 5 hours ago.

Found the raspinfo command. Here's the output.

0b is likely to be a length (11), and the values which are between 61 and 7a are all lower case ASCII values... _googlecast_tcplocal

Ah, an online packet analyser - https://hpd.gasmi.net/?data=4500004419930000FF11FF08C0A80169E00000FB14E914E90030E8960000000000010000000000000B5F676F6F676C6563617374045F746370056C6F63616C00000C0001&force=ipv4

So whilst that does appear to be a valid packet, at least you now know the source of your woes, and it is multicast related.

[ralphrmartin]

192.168.1.105 is a MacBook; it has Google Chrome as a browser, which can "cast". There's also a Sony Bravia TV on the network with an inbuilt service for receiving casts. (I was not "casting" anything at the time of the hw csum failures though).

I have not recently updated the software on the TV, although I have recently installed the latest system update and Chrome on the MacBook.

So, we can see what kind of packets are triggering the problem. Now what?

[6by9]

So, we can see what kind of packets are triggering the problem. Now what?

Now someone at least has a chance of recreating your problem. Doing so may be non-trivial though.

[ralphrmartin]

Thank you. Let me know if I can do anything to assist, try out proposed changes, etc. (Sorry if my "now what" came across the wrong way - it was meant in the spirit of "what can I do to help?", but I can see now it hardly sounds like it).

[ralphrmartin]

In case anyone else has this issue, a temporary way to prevent the flood of messages from swamping logs is to do ethtool -K eth0 rx off (this does nothing to resolve the underlying cause of the problem).

[ralphrmartin]

Problem still present in 5.10.17

[pelwell]

And it still appears to be a problem only affecting one person. If you want some engineering effort put into this you'll have to make some attempts to work out what in your environment is triggering this bug by changing your configuration until the errors stop:

• Remove PoE - power the Pi using a conventional power supply.
• If you have another Ethernet switch, even a small one, try interposing that between the Pi and the Unifi.
• Close down Chrome. And if that makes no difference, turn off the MacBook.

Those three changes give 8 possible combinations. I would start by making as many changes as possible - if the problem still occurs then you've just ruled out several causes but now need to think of some more.

[ralphrmartin]

(1) Problem persists when powered by official wall wart instead of PoE. (2) Problem persists when powered by official wall wart, connected via IP Phone instead of via Unifi switch. (3) Problem persists when instances of Chrome are shut down on Macs. (4) Problem persists when all Macs are shut down. (5) Problem persists when TV is turned off.

Note that Chrome may be running on Android phones on this network; it is not practical to try to stop it on them, nor is it practicable to turn these phones off.

This probably deoesn't help, but I have a Debian (testing) system on a Dell laptop on the same network, and there are no similar messages in its syslog.

If you have further ideas of what else to try, need more logs, etc, please let me know.

[pelwell]

I have a Debian (testing) system on a Dell laptop on the same network, and there are no similar messages in its syslog.

Assuming this isn't some marginally faulty hardware, this is likely to be a bug in the GENET Ethernet controller, or more likely its driver.

How long does it typically take to see the problem? I have a Unifi Amplifi at home, and it might conceivably show the same issue.

[ralphrmartin]

The chance of dodgy hardware is low as the 2 RPi 4's involved were bought quite a long time apart. As soon as either RPi starts, the errors start coming in. Just in case it is relevant in any way, both boot from a USB attached SanDisk SSD.

[ralphrmartin]

The switch is a Unifi US-8-150W, running 5.43.23.12533, in case that is useful.

[ralphrmartin]

MTU is set to 1500 on this network.

[pelwell]

If it is at all possible to briefly take your AP (and hence the mobile clients) out of the equation it would be a useful experiment. Note again that we're just trying to pinpoint the necessary elements to recreate the problem.

[6by9]

Analysing a couple more of the skb dumps from the log (just the skb linear bits), they're all sorts of traffic.

• SSH and a TCP ACK between 192.168.1.100 and 192.168.1.105
• mDNS multicast query
• broadcast from 192.168.1.101 to UDP port 32412 (Plex).

There are also a couple which appear to be random fragments, as they don't start with IP headers (expect 45 00 at the start for a standard IPv4 packet). There is an IP header in the headroom, but it implies something odd is going on.

The SKB dumps only show the IP layer of the data. Grabbing a short wireshark dump may be of more use.

[ralphrmartin]

It was not practical to turn the APs off (there are five off them, used for real time monitoring and control). However, I did manage to briefly turn off all Android and iOS devices that might be running Google and the problem persisted.

[ralphrmartin]

If you can tell me the wireshark command line to use I'll collect some info. Does this need running on the RPi, or will any device on the net do to collect traffic? Where should I put the collected data (given that it may have private info in it)?

[ralphrmartin]

Tried a 64-bit kernel to see if it made a difference. Still got errors, as was to be expected.

[ralphrmartin]

An RPi 3B with the same kernel, connected to the same switch, does not show these errors.

[6by9]

Pi3 uses a totally different ethernet chip so it's totally expected that it won't show issues. It would only do so if the problem was in the networking core code, and that sort of issue would be picked up fairly swiftly.

[ralphrmartin]

As I say, I'll try to collect a wireshark capture if you give me some instructions.

[ralphrmartin]

Finally tracked down the cause of this problem. Because of other ethernet issues I had earlier, I had genet.skip_umac_reset=y in my cmdline,txt. Changing it to genet.skip_umac_reset=n stopped the flood of hw csum failure errors.

[Omoeba]

I'm facing the exact same issue on kernel version 5.10.17-v8+. Adding genet.skip_umac_reset=n to my cmdline.txt didn't change anything.

[Omoeba]

The only way to stop the dmesg flood is ethtool -K eth0 rx off.

[noroutine]

just chiming in that same occured for me, no special networking, no special configuration for skip_umac_reset

Fingers crossed for 6.1 test this weekend. Issue persists on 5.10.176. MLD / Android triggers.

And while this commit is likely not directly related? Comment sounds very on point with what I suspect is going on in the nic driver on 5.10 / 5.15...

https://github.com/raspberrypi/linux/commit/331615d837f4979eb91a336a223a5c7f7886ecd5

edit: good news, unable to reproduce on 6.1, this environment excludes most packet handling stuff used previously. so bug could be gone or just no longer triggering. should anyone happen to come across such messages in future, would advise digging into anything uniq to their system doing packet/frame/etc alteration. specifically, when multicast runts and giants are encountered or similar...

After I added ifb device ( for ingress shaping ) , This error occurs.
