Additional context I appended genet.skip_umac_reset=n to my /boot/cmdline.txt as per #4184 and the issue kept occurring. The only way to stop the flood is sudo ethtool -K eth0 rx off. The issue also occurs in kernel versions 5.10.17-v7l+ and 5.10.11-v7l+. I haven't tested 5.10.11-v8+.

Omoeba commented 3 years ago

The issue persists in kernel 5.10.31-v8+

pelwell commented 3 years ago

Try giving some information about your network architecture - this isn't affecting many people or GitHub would be flooded, so what might make your environment different?

pelwell commented 3 years ago

And what is host 84:8a:8d:32:c4:19, that is sending IPV6 all-nodes multicasts? It appears to be a Cisco device.

6by9 commented 3 years ago

The online decoder I found when last looking at this says we have an ICMPv6 Router Advertisement. https://hpd.gasmi.net/?data=6000000000203AFFFE80000000000000868A8DFFFE32C419FF02000000000000000000000000000186008D1540C007080036EE80000000000101848A8D32C41905010000000005DC&force=ipv6

And a couple of ICMPv6 Multicast Listener Query (130) https://hpd.gasmi.net/?data=6000000000240001FE80000000000000868A8DFFFE32C419FF0200000000000000000000000000013A0005020000010082007FC02710000000000000000000000000000000000000027D0000&force=ipv6

No specific reason why these messages would flag invalid checksums.

It does look like there's something odd about your network though with IPv4: martian source 192.168.1.69 from 169.254.124.175, on dev eth1 being logged several times in there. Are you bridging between eth0 and eth1 or similar?

Omoeba commented 3 years ago

84:8a:8d:32:c4:19 doesn't appear to be connected to my network anymore. I am indeed forwarding traffic between eth0 and eth1 with eth1 connected to the LAN and eth0 connected to the WAN. I'll try disconnecting eth1 completely and see if the issue persists.

pelwell commented 3 years ago

It would be interesting to see if the problem recurs with traffic from another device, and if so what kind of traffic it is.

Omoeba commented 3 years ago

The problem still occurs with eth1 completely disconnected. I'll try plugging eth0 into my pc instead of a SB8200 cable modem tomorrow and see if the issue persists.

Omoeba commented 3 years ago

Plugging the pi directly into my pc caused the issue to disappear despite throwing every kind of traffic I can think of at it. I’ll try the 5.4 bcmgenet driver since I don’t recall the issue occurring prior to 5.10.

Omoeba commented 3 years ago

The 5.4 bcmgenet driver failed to compile so I unfortunately couldn't test it. However, since I don't recall the issue occurring prior to 5.10, it's likely some change between 5.4 and 5.10 that caused the issue.

ralphrmartin commented 3 years ago

See also #4184, and what resolved the issue for me. I'm not sure if it is relevant here.

Omoeba commented 3 years ago

I've done some additional testing and the issue began at kernel version 5.6. No log flooding occurs when rx offloading is enabled on versions 5.4 and 5.5 while 5.6 immediately started flooding syslog with csum failure messages. I still have no idea which particular commit caused the issue but it's narrowed down significantly.

wulfy23 commented 3 years ago

what makes my environment different

openwrt with possible non-coherant testing patchset for initial support
sqm, ctinfo (packet steering to alt cpu)
eeprom 8 months old maybe

it does seem to be somewhat environmental... another user of my build has reported no errors... I do recall on 5.4 tcpdump indicating cksum issues on the same icmpv6 traffic... so it seems that in the past... these things were non critical and handled/passed by/to upper layers...

may have seen 'ifb' in the OP's crashdump... i'm also using an ifb via cake/sqm... perhaps a common denominator here? ( ipv6 + ifb )

@Omoeba if you have an ipad or similar idevice on your network...

can you reproduce with all idevices disconnected?

openelectron commented 3 years ago

Not sure if its helpful, but, I have a custom CM4 carrier board (with poorly tracked Ethernet) this causes the same problem. Moving the same CM4 module to the official carrier board fixes the problem.

My only workaround was to limit the ethernet to 100Mbit using; ethtool -s eth0 speed 100 duplex full

I do but the issue still occurs with eth1 completely disconnected and eth0 is the internet-facing interface

Observed this when uploading TB volume data with rclone from a RPi4 to AWS S3. The RPi is directly connected via Ethernet to a Verizon Fios Optical Network Terminal exposing 1Gbit upstream connection. Transfer happened at around 400MBit/s.

fwiw there was an interesting post in an openwrt bug report regarding this afair fingering network "scaling" subsystems... which was my initial gut feeling on this due to prevalence.

i tend to agree with that, however it's occurrence or more importantly lack thereof across similar and dissimilar hardware is pointing me towards actual core/buffer??? (re)allocation for the above as key here...

just a laymans theory with nothing to substantiate so grain of salt and all of that...
