qemu-aarch64-static segfaults running ldconfig.real (amd64 host)

Bug description:
This affects the qemu-user-static 1:8.2.2+ds-0ubuntu1 package on
Ubuntu 24.04, running on a amd64 host.
When running docker containers with Ubuntu 22.04 in them, emulating
arm64 with qemu-aarch64-static, invocations of ldconfig (actually
ldconfig.real) segfault. For example:
$ docker run -ti --platform linux/arm64/v8 ubuntu:22.04
root@8861ff640a1c:/# /sbin/ldconfig.real
Segmentation fault
If you copy the ldconfig.real binary to the host, and run it directly
via qemu-aarch64-static:
$ gdb --args qemu-aarch64-static ./ldconfig.real

I'm using quemu to tweak Armbian Jammy images for Raspberry Pi 5 (so it
would have ldconfig from 22.04) and I have signal 11 when libc
reconfiguration is triggered by apt.
What you may find interesting running the same process of updates on the
same base image on Ubuntu 22.04 (which has qemu 6.2) works fine.
My googling around "libc signal 11 quemu" lead to a lot of people
reporting problems with docker buildx with qemu predating 7.0. This
smells kind of regression in 8.2 used in 24.04. Then the issue linked
above says affected ldconfigs are 2.33 to 2.35...
Does Ubuntu really need to wait for upstream to deal with this? It's a
huge slap in the face for everyone on 24.04 needing to meddle 22.04
ARM64 images.

FWIW, I left a comment on the bug report asking for guidance, because it
seems to me that just reverting the commit mentioned above isn't the
right solution (as we'd be reintroducing the bug fixed by the commit).

Hi, this issue also happens when I try to run debootstrap for Jammy
arm64 on a Noble amd64 host. At the moment I use the workaround to use
ubuntu:jammy workers instead of ubunut:latest. It would be great if this
issue can be fixed soon.

Hi,
this came up in our dormant bugs checker ...
There was no reply from upstream yet, but I agree that a blunt revert might be wrong unless they agree.
Sergio reached out, but probably needs to kindly ask again with some extra noise.

Ubuntu 24.04, running on a amd64 host.
When running docker containers with Ubuntu 22.04 in them, emulating
arm64 with qemu-aarch64-static, invocations of ldconfig (actually
ldconfig.real) segfault. For example:
$ docker run -ti --platform linux/arm64/v8 ubuntu:22.04
root@8861ff640a1c:/# /sbin/ldconfig.real
Segmentation fault
If you copy the ldconfig.real binary to the host, and run it directly
via qemu-aarch64-static:
$ gdb --args qemu-aarch64-static ./ldconfig.real

Upstream has committed https://gitlab.com/qemu-
project/qemu/-/commit/4b7b20a3 which fixes the segfaults. A prerequisite
for the qemu 8.2.2 package in Ubuntu 24.04 is https://gitlab.com/qemu-
project/qemu/-/commit/c81d1faf, so here is a patch that includes both.

Thank you!
Adding to plucky soon and then planning SRUs as the queue gets freed of the former one in flight.

This affects the qemu-user-static 1:8.2.2+ds-0ubuntu1 package on
Ubuntu 24.04, running on a amd64 host.
When running docker containers with Ubuntu 22.04 in them, emulating
arm64 with qemu-aarch64-static, invocations of ldconfig (actually
ldconfig.real) segfault. For example:
$ docker run -ti --platform linux/arm64/v8 ubuntu:22.04

Segmentation fault
If you copy the ldconfig.real binary to the host, and run it directly
via qemu-aarch64-static:

This affects the qemu-user-static 1:8.2.2+ds-0ubuntu1 package on Ubuntu 24.04, running on a amd64 host.

That's 1.9.x line - is it going to be backported to Noble? That's LTS we
plan to use for next couple of years and this qemu problem is hitting us
hard.

If you look at the top of this bug, you can see the two merge requests put in by Lukas, one for noble and one for oracular:
* https://code.launchpad.net/~slyon/ubuntu/+source/qemu/+git/qemu/+merge/481940
* https://code.launchpad.net/~slyon/ubuntu/+source/qemu/+git/qemu/+merge/481943
My guess is that the noble-devel and oracular-devel branches are the
places where the proposed update packages are built from, which will
eventually end up in the regular updates. But no idea how long that
usually takes.

Given this possible regression:
* This changes the alignment of sections in the ELF binary via QEMUs elfloader, if something goes wrong
with this change, it could lead to all kind of crashes (segfault) of any emulated binaries.
Is there something we could do to mitigate it? Perhaps a quick similar
ldconfig test in other emulated scenarios?

Hello Dimitry, or anyone else affected,
Accepted qemu into oracular-proposed. The package will build now and be
available at

to enable and use -proposed. Your feedback will aid us getting this
update out to other Ubuntu users.
If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
oracular to verification-done-oracular. If it does not fix the bug for
you, please add a comment stating that, and change the tag to
verification-failed-oracular. In either case, without details of your
testing we will not be able to proceed.
Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in
advance for helping!
N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in

All autopkgtests for the newly accepted qemu (1:8.2.2+ds-0ubuntu1.7) for noble have finished running.
The following regressions have been reported in tests triggered by the package:
glance/2:28.1.0-0ubuntu1 (amd64, arm64, ppc64el)
livecd-rootfs/24.04.87 (s390x)
Please visit the excuses page listed below and investigate the failures, proceeding afterwards as per the StableReleaseUpdates policy regarding autopkgtest regressions [1].

This affects the qemu-user-static 1:8.2.2+ds-0ubuntu1 package on Ubuntu 24.04, running on a amd64 host.
When running docker containers with Ubuntu 22.04 in them, emulating
arm64 with qemu-aarch64-static, invocations of ldconfig (actually
ldconfig.real) segfault. For example:
$ docker run -ti --platform linux/arm64/v8 ubuntu:22.04
root@8861ff640a1c:/# /sbin/ldconfig.real

If you copy the ldconfig.real binary to the host, and run it directly
via qemu-aarch64-static:

me.
With 8.2.2+ds-0ubuntu1.6, running a Docker container with Ubuntu 22.04,
targeting arm64 on an amd64 host, and upgrading the libc package results
in:

With 8.2.2+ds-0ubuntu1.7, this problem does not appear, and building the
container works fine.

The verification of the Stable Release Update for qemu has completed
successfully and the package is now being released to -updates.
Subsequently, the Ubuntu Stable Release Updates Team is being
unsubscribed and will not receive messages about this bug report. In
the event that you encounter a regression using the package from
-updates please report a new bug using ubuntu-bug and tag the bug report
regression-update so we can easily find any regressions.

--- original bug report ---
This affects the qemu-user-static 1:8.2.2+ds-0ubuntu1 package on Ubuntu 24.04, running on a amd64 host.
When running docker containers with Ubuntu 22.04 in them, emulating
arm64 with qemu-aarch64-static, invocations of ldconfig (actually
ldconfig.real) segfault. For example:
$ docker run -ti --platform linux/arm64/v8 ubuntu:22.04
root@8861ff640a1c:/# /sbin/ldconfig.real
Segmentation fault
If you copy the ldconfig.real binary to the host, and run it directly
via qemu-aarch64-static:
$ gdb --args qemu-aarch64-static ./ldconfig.real

It looks like this is a known qemu regression after v8.1.1:

Downgrading the package to qemu-user-
static_8.0.4+dfsg-1ubuntu3_amd64.deb fixes the segfault.
