same issue - router useless
Model Asus RT-AC51U
Architecture MediaTek MT7620A ver:2 eco:6
Firmware Version OpenWrt 19.07.4 r11208-ce6496d796 / LuCI openwrt-19.07 branch git-20.265.67308-c1fc83b

Internet commented on 26.09.2020 20:43

it seems it happens more often when there is less free memory when more processes are running, but free memory is still about 20 MB according to "Overview" page,

Hi,
I hit this issue too with:
SoC Type: MediaTek MT7621 ver:1 eco:3
MIPS: machine is UBNT-ERX
Kernel: 4.14.209
openwrt: 19.7 d83040313390f56c22ff020f0f20da8f05e98e35

I have this version deployed on approximately 50 routers in our network. It looks like the network traffic is the trigger, but I'm not sure. Before applying this patch https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=34a96529041d4e9502c490c66f8af0154187c6d2 I can reliably reproduce this in lab environment with sending trafic out "dd if=/dev/zero bs=4k |nc -u 10.19.19.194 887" and simultaneously send many small packet with random dst port through the router from packet generator.
This conditions raliably generate message like log below. With last version from 19.7 branch I can't reproduce this in lab environment but in production environment this occurs randomly several times a day.

And this sometimes leads to kernel panic in (skbuff: skb_over_panic:) and reboot. Crashlog from two routers in production is attached.

If anyone has an idea how to fix it. I can check in a very short time if the error is fixed. Or extract more debug information.

I can confirm I saw this warning on UBNT-ERX with 19.07.2 / kernel 4.14.171:

We also had one unexplained crash in production in the past year, so it's probably related. The device doesn't see a lot of traffic.

mrakotiq commented on 11.12.2020 10:19

And sometimes this "transmit timed out" leads to the sending of the malformed packets just after "mtk_soc_eth 1e100000.ethernet: PPE started" appears in log. For example, the packet type is 0x8100 but 4B defining the vlan tag is missed and this leads to misinterpretation of the ip header as a vlan tag.

mrakotiq commented on 14.12.2020 16:44

I can reproduce this in lab environment very reliably again.

Please, if anyone has an idea of what I should try or what I should focus on. Let me know.

mrakotiq commented on 16.12.2020 16:21

Can someone please confirm that this is the right place to report issues like this?

May someone notice authors of this driver (John Crispin, Felix Fietkau, Michael Lee) to this thread. Because I thing no one else here seems to have enough experience to solve this strange problem. :(

mrakotiq commented on 22.12.2020 14:35

This little patch solved the "mtk_soc_eth 1e100000.ethernet eth0: transmit timed out". At least for now. Now it cannot be reproduced in a lab or on a 75pcs routers in network.

Please try someone too and confirm if it helped.

Good catch, well done!

I had a look and this driver was removed upstream: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=bd31342f0046077e92062a6c09eae6c8f1676916

Upstream is using the generic mediatek driver, and this is also what is used in OpenWrt master with kernel 5.4. The generic driver does enable TSO, so TSO is likely a symptom and not the root cause.

Have you noticed any performance regression when disabling TSO? Did you try to reproduce the issue on latest OpenWrt master?

mrakotiq commented on 22.12.2020 21:17
so TSO is likely a symptom and not the root cause.

I agree, but obviously it has something to do with it.

performance regression when disabling TSO

It's too fresh and I don't do any performance tests yet, but there is no visible difference in the avg load and cpu usage graphs. So if there is an impact, then only insignificant

mrakotiq commented on 22.12.2020 21:19
Did you try to reproduce the issue on latest OpenWrt master?

Unfortunately, I don't have time for this yet.

Baptiste Jonglez commented on 07.02.2021 23:30

I'm trying to reproduce the crash to test your fix. Are you still using the same method to reproduce? ("dd if=/dev/zero bs=4k |nc -u 10.19.19.194 887 and simultaneously send many small packet with random dst port through the router from packet generator")

Also, did you have flow offloading enabled? (soft, hard?)

It's a bit strange that you reproduced this with UDP traffic if the issue is related to TSO (because it should only apply to TCP).

I'm hoping we can integrate a fix (or at least a workaround) for the upcoming 19.07.7 point release.

Project Manager
Baptiste Jonglez commented on 08.02.2021 22:45

I am not able to reproduce with a current 19.07 snapshot (self-build, r11297-4465b44fc1). I have been sending 32 iperf3 UDP flows with small packets + iperf3 TCP flows through the router, and also sending UDP packets from the router itself with "dd if=/dev/zero bs=4k |nc -u ". No crash in 24h, with and without software flow offloading.

So, either:

1) it has been fixed (but I don't see how, except maybe for a kernel bump)
2) it is hard to reproduce
3) it depends on build parameters
4) it depends on runtime parameters like VLAN configuration

mrakotiq commented on 09.02.2021 08:30

I'm currently in time press, so only briefly

Later I reliably reproduced the problem by sending a UDP packet with:
dd if=/dev/urandom bs=4k |nc -u 10.19.19.194 888
And replayig pcap through router from my workstation (eth1: RTL8168evl/8111evl, gso,tso off ) with command:
tcpreplay-edit -l 50 -F pad –enet-dmac=74:ac:b9:a2:5a:5a,74:ac:b9:a2:5a:5a -i eth1 ./linuxbox.pcap

Pcap was captured in real network where he caused this error. Because it may contain sensitive data, I will send it to you by email.
By this procedure I was able to reproduce the error every time tcpreplay was run.

For udp stream it is necessary to pay attention so that an icmp packet does not return from somewhere, which could stop the flow. And verify that the packets from tcpreplay are actually passing through the router

BTW: When I have time, I will try to reproduce this with the current build.

Chernobyl commented on 13.02.2021 17:08

Still seeing this bug in the (near) latest snapshot. Software offloading enabled, hardware offloading disabled.

Any suggestions to try?

Thanks, with your input I can reproduce a crash (RCU stall). It takes a few hours. I did not have any offloading enabled.

I am unable to reproduce on latest master, but that is not surprising, it's using a different driver.

I'm now testing a variant of your patch.

Baptiste Jonglez commented on 15.02.2021 10:16

Disabling TSO makes things more stable, with a small hit on forwarding performance.

While it's probably not a complete fix, I have pushed this as a workaround for the next 19.07.7 release: https://git.openwrt.org/f8b849103dfe1b21a6462837efc9460ca3cca02d

I built a custom 19.07-SNAPSHOT r11306 for my UBNT-ERX-SFP and installed it last night. No hiccups yet in 20 hours of uptime (but it would often run for several days with no errors before). I'm on gigabit symmetrical GPON and there has been some impact on performance, but I prefer the increased stability (it it works!).

Booo!! It's still there - see below. The router didn't crash though - in fact, I never even noticed a blip (I was online working at the time), but something bad is still going on. So this is not the fix either. I'm starting to think this driver is hopeless until I switch to the 21.0x branch and the new kernel.

Yes, I can confirm that.

NETDEV WATCHDOG: eth0 (mtk_soc_eth): transmit queue 0 timed out
will occasionally occur but will not cause any damage.

Nigel Reed commented on 01.03.2021 02:59

I'm using a Netgear R6220 router and having the same issues.

I was using a snapshot from probably back in April last year and everything was working fine. I decided to experiment with i2pd, unfortunately my file system was rendered read-only due to filling up. I decided I was going to do 2 things.

1. Upgraded to the latest 19.07.7
2. extended the filesystem to a USB stick following the instructions at: https://openwrt.org/docs/guide-user/additional-software/extroot_configuration

The router seems to lock up overnight when it's not being used as much but it's random.

Thor Johansen commented on 05.03.2021 00:36

Problem still occurs with 19.07.7 on Mikrotik RB750gr3. I see these errors on my rsyslog server on a daily basis. They don't seem to cause a problem most of the time, but occasionally a router will become unresponsive and needs to be power cycled. I can't verify whether this error is also what causes the hangs, but given how many people are seeing this error message in connection with such hangs, it seems to be the likely culprit:

I might attach a serial console to one of my routers to see if I can catch it red-handed. I hear this isn't an issue with the new kernel on the master branch, but I would much prefer to wait until there is a tagged release with a seamless migration path away from swconfig, with a working LUCI GUI for the switch.

Nigel Reed commented on 05.03.2021 06:59

I've updated my Netgear R6220 router to the latest snapshot at the time of compilation and it's been up and running with no issues for 48 hours apart from one of the ports flapping. I m moved the cable to another port and that stopped it so everything is stable including ddns updates, ipv6 in ipv4 tunnel with HE, etc.

Thor Johansen commented on 05.03.2021 08:40

Snapshots are taken from the master development branch, which has migrated to a new Linux kernel that uses a completely different Ethernet driver. It doesn't have the same issue. As I understand it, the official releases are largely backports at this point. I expect that there will be an official release based on the master branch at some point.

The bug will disappear when this migration happens. In the meanwhile, I hope they'll fix this in an official release, because it's a major pain point for me.

Device: Mikrotik RB750Gr3

This problem still persists with OpenWrt 19.07.7 without crashing the router.
In my case it's rare to see it happen, but this bug is not gone.

I had a hard lock last night on the following hardware/software version. System froze, not allowing connections via http or ssh until I unplugged it to reboot. Stability is greatly improved from the previous release, though.
I remember testing master about 3 months ago and still having hard locks on this hardware as well.
