## 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**+ gitlab-org/gitlab-runner#1 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 <!--Please add the definition of the job from `.gitlab-ci.yml` that is failing inside of the code blocks (```) below.--> <details> <summary>.gitlab-ci.yml</summary> ```yml ``` </details> ## 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. ## Relevant logs and/or screenshots <!--Paste the job logs inside of the code blocks (```) below so it would be easier to read.--> <details> <summary>job log</summary> ```sh Running with gitlab-runner 18.4.0~pre.115.gb2218bab (b2218bab) on blue-3.saas-linux-small-amd64.runners-manager.gitlab.com/default zxwgkjAPH, system ID: s_d5d3abbdfd0a Resolving secrets Preparing the "docker+machine" executor Using Docker executor with image registry.gitlab.com/exfo/products/tandm/tandd/field-of-dreams/container-registry/cpp-dotnet-ci:9.0-amd64 ...
