Bug #1735546 “[hyper-v] reloading netvsc issue on linux-azure 4....” : Bugs : linux-azure package : Ubuntu

Adding this issue here, as in the past we saw linked issues between netvsc reload and mtu change.

The same hung task failure occurs when changing the MTU on the interface.

Repro steps:
ip link set dev eth0 mtu 3000
ip link set dev eth0 mtu 4500

At this point the command will hang and then run into the hung messages after 120 seconds.

I can't reproduce the issue with 4.13.0-1004-azure-edge (https://git.launchpad.net/~canonical-kernel/ubuntu/+source/linux-azure/commit/?h=azure-edge-next&id=21d8a99f88af972684618521cf19adafe24dc566)

It looks this bug has been fixed by some patch between linux-azure 4.13.0-1001.1 and 4.13.0-1004-azure-edge.

BTW, I tested "modprobe -r hv_netvsc; modprobe hv_netvsc" and "ip link set dev eth0 mtu 3000; ip link set dev eth0 mtu 4500" with 4.13.0-1004-azure-edge on WS 2016 (Version 1607, OS build 14393:1943).

After having had a chat with Josh Poulson @Microsoft, it is believed that the pull request in bu https://bugs.launchpad.net/ubuntu/+source/linux-azure/+bug/1736283 should likely resolve the issue seen here. We will post a test kernel in bug 1736283.

@leann Actually I'm not sure if the pull request in bug 1736283 can fix this bug. It looks 4.13.0-1004-azure-edge has already fixed this bug somehow.

Hrm, interesting. Thanks for the note, I'll circle around with the team here to see what the discrepancy might be.

This is indeed very odd. Examining both code bases, we don't see any significant difference. The source code is the same, as well as the configs and the module inclusion lists. We're checking if we can reproduce bug 1736283.

@jpoulson probably knows the answer, but were both linux-azure and linux-azure-edge tested in the same manner?

Dexuan,

Are you using gen1 or gen2 VMs?

Also, which specific builds of linux-azure and linux-azure-edge are you using? Are you using any versions from http://kernel.ubuntu.com/~mhcerri/azure/?

Right now only Generation 1 VMs are used in Azure.

I couldn't properly verify the problem on azure. If I execute:

sudo sh -c 'modprobe -r hv_netvsc; modprobe hv_netvsc'

on an azure instance I lost SSH connection, but I don't see the hung task messages on the boot diagnostics windows. The problem is probably happening and maybe I'm not getting the messages.

When I run on a local hyper-v gen2 VM, I can trigger the problem when I do the following sequence:

modprobe -r hv_netvsc
modprobe hv_netvsc
modprobe -r hv_netvsc

And I can reproduce the issue with linux-azure 4.13.0-1001.1, with linux-azure-edge 4.13.0-1004.4 and even with linux-azure 4.13.0-1001.1 with the pull request changes.

I will re-test it using a gen1 VM.

I only tested Gen1 VM (4.13.0-1004-azure-edge) on my local Hyper-V host (WS 2016), and couldn't repro the issue, i.e. reloading hv_netvsc and changing MTU worked fine.

As I understand, I think the bug was originally reported against 4.13.0-1001.1 (I did not test this version). That's why I think somehow the bug was fixed in 4.13.0-1004-azure-edge.

Ubuntu-azure-edge-4.13.0-1001.1 is 567ef14ee13c5c4e336121106cc19733800d618e, and
Ubuntu-azure-edge-4.13.0-1004.4 is 21d8a99f88af972684618521cf19adafe24dc566.

There are non-trivial changes between them:

@decui

The repos are right. I'm asking because some of the kernel under http://kernel.ubuntu.com/~mhcerri/azure/ are testing kernels.

linux-azure and linux-azure-edge version numbers are not equivalent. Thus, linux-azure 4.13.0-1001.1 is not equivalent to linux-azure-edge 4.13.0-1001.1. In fact, linux-azure 4.13.0-1001.1 should be equivalent to linux-azure-edge 4.13.0-1004.4.

Are you building the kernels directly from the git repo or are you using binary packages from somewhere?

Ok. I've tested it again using gen1 VMs and I got the same results. Both linux-azure and linux-azure-edge show the problem, but for both cases I need to unload, load and unload the driver again to trigger the issue.

I also tested the test kernel with the pull request and it shows the same problem. I will double check that build to make sure everything was correctly applied.

I'm using Hyper-V on a Win10Pro machine.

@mhcerri
Thanks for the explanation! I built the kernels directly from the git repo and I didn't use the binary packages (I thought they should be the same). What's your repro-rate? Yesterday as Chris tested linux-azure-edge 4.13.0-1004.4 + my pull request, the repro rate was only ~1%, meaning we have to do "unload/reload netvsc" several hundred times to repro the hang or the calltrace. Previously without the pull request, Chris mentioned it was much easier to repro the issue. So it looks to me the bug is timing-sensitive, and somehow my pull request made it difficult to repro it.
