Current gitlab-runner linux kernel is at version 5.15.154+ but need a kernel version of >= 6.1.0 to perform BDD tests on ipv6 feature.

Summary

Hi,

I'm currently working on BDD tests for IPv6. Some of these tests pass perfectly in our debug environment but consistently fail in GitLab.

After investigating, it seems that the GitLab runners are running a Linux kernel version that's too old (probably the kernel version of the host).

We need a kernel version of >= 6.1.0.

Kernel version on the GitLab runner:
uname -a
Linux runner-zxwgkjaph-project-44869153-concurrent-0 5.15.154+ #1 (closed) SMP Sat May 4 12:14:42 UTC 2024 x86_64 GNU/Linux

Do you think it would be possible to get GitLab runners with a more recent kernel?

Tanks

Steps to reproduce

Run a job on and check kernel version.

#12270835 (zxwgkjAP) 3-blue.saas-linux-small-amd64.runners-manager.gitlab.com/default

.gitlab-ci.yml

Actual behavior

Ipv6 neighbor advertisement are not sent and received by the linux kernel.

Expected behavior

Ipv6 neighbor advertisement should be sent and received by the linux kernel.
