Package: src:linux
Version: 6.0.10-1
Severity: important
File: nfsd

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

* What led up to the situation?

On testing/bookworm, since booting on a 6-versioned linux-image, I have
noticed frequent hang ups of the nfs server, rendering it mostly
unusable. This is accompanied with Kernel Oops in the dmesg.

This sounds similar to previous bugs #1014793 and #1020548, both RESOLVED by
later patches.

* What exactly did you do (or not do) that was effective (or
ineffective)?

Upgrade from a 5.19 series kernel to a 6-series

* What was the outcome of this action?

The issue started happening.

* What outcome did you expect instead?

NFS would still be accessible as before (:

The clients are recent Linux hosts, and one Kodi 19.x. I don't specify a
version in either their fstab or the server's exports.

From my reading of the manpages, it seems that the client will start
from 4.2 and go down.

For the server, it _may_ vary due to the /etc/exports. I include mine
below, as I'm not certain how to understand the `fsid` logic, though I
think in my case it's a simple tree rooted at /.

How easy can you trigger and reproduce the issue? If you can easily
reach that situation, can you try to bisect the issue? Easiest would
be to first pin point between Debian revisions, and later further
bisect in upstream stable series.

Do you have the possibility to do that?

It seems to be fairly reliable.

I'll give that a go, starting with
* linux-image-5.19.0-2-amd64_5.19.11-1_amd64.deb
* linux-image-6.0.0-1-amd64_6.0.2-1_amd64.deb

I'm not certain how to bisect further. Which source and which kconfig
should I use to build intermediate commits?

Great, thanks.

Does the following reference helps you further?

Thanks for taking time for pinpointing your issue.

Package: linux-image-5.19.0-13930-g7ebfc85e2cd7
Version: 5.19.0-13930-g7ebfc85e2cd7-23
Followup-For: Bug #1025537

Ok, so the bisect got me down to commit 7ebfc85e2cd7b08f518b526173e9a33b56b3913b
(v6.0-rc1~28). This is unfortunate, as it is quite a large one [0].

A caveat to this report is that I'm not 100% sure my way of triggering
the issue always worked. This commit OOPSed the first time round, but
when it was found to be the first faulty commit at the end of the bisect
pass (logs below), I could no longer trigger the bug on a newly rebuilt
kernel off the same commit. I now realise that I didn't clean between
builds, but I assume `make bindeb-pkg` would start from a fresh clean
state.

This commit doesn't seem to directly touch NFS code, but does touch
the networking state, so it is still a plausible suspect.

As per my previous message, the latest kernel also exhibit the issue.
Worse so, it seems to even hang the kernel, which didn't seem to happen
on earlier versions.

Ah, here we go! It just Oopsed again, on what is presumably the first

I'm gonna try to buidthe previous commit and see if it's happy for a
while.

Nope... I just re-triggered the Oops on the preceding commit, e091ba5cf827.

I'll restart the bisection from there...

OK, I think I have a strong suspect [0]:

f0f6b614f83dbae99d283b7b12ab5dd2e04df979 (tags/v6.0-rc1~55^2~2)

This is a pretty generic commit, that doesn't seem to touch the nfs
stack, but changes something that looks deep enough in the iovec code
that it could have an impact.

I have solidly re-tested the preceding commit,
310d9d5a5009a93377200b98daa2d84aa2bd8160 (tags/v6.0-rc1~55^2~3), and
the Oops doesn't happen there.

There is a series of commits that were suggested as part of the `git
bisect`, that I wasn't able to build and had to skip. The error was

FAILED: load BTF from vmlinux: Invalid argument

but no amount of cajoling `pahole` has helped.

The merge parent for the series is at
8447d0e75099eb54eea9306c2d43ecfc956d09ed (tags/v6.0-rc1~56^2), which is
the preceding merge to the one containing the first bad commit above. I
think this is noteworthy as a lot of the commits on this branch are
labeled as `remoteproc` which I, as a lay person, think might be related
to RPCs.

Is there any other tests that I can perform to help diagnose / fix this
further?

The 6.1.0 Changelog had some notes about a gnarly bug in the NFS bug
having been fixed, so I thought I'd give it a try. Unfortunately, the
problem reported here is still present. It has made the machine quite
unstable, but I was able to retrieve logs of previous Oopses.

The machine rebooted after that (maybe due to the watchdog, so it might
have hanged).

I'm at a bit of a loss as to how I can investigate this further, or fix,
so I'd be happy for suggestions.

Followup-For: Bug #1025537

Dear Maintainer,

Just a heads up that, after some uptime and an utimely reboot, I am now
on 6.4.0-3, which no longer seems to exhibit the issue from earlier 6.x
series.

While we didn't get to the root cause, I think this bug can be
tentatively closed.
