Hi @eiffel-fl. Thanks for your PR. I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with Once the patch is verified, the new status will be reflected by the I understand the commands that are listed here.

Can one of the admins verify this patch? |
This config option permits indicating the Linux kernel needs pahole to be compiled. Thus, host-pahole will be built before the kernel. This is mandatory when using CONFIG_DEBUG_INFO_BTF. Signed-off-by: Francis Laniel <[email protected]>

Thank you a lot for the merge :D :D :D! |

I'm ecstatic that this has been merged! Thanks a lot, @eiffel-fl, for the amazing work! Can we just use it? Will there be a release candidate that includes new Kernel upgrades? Or is there an easy way to grab an image from the merged commits? |

Hi @ALL, I'm trying to run ebpf programs with the latest minikube version (1.26.0), but it is not working. $ minikube ssh -- docker run --rm --privileged -v /lib/modules:/lib/modules:ro -v /usr/src:/usr/src:ro -v /etc/localtime:/etc/localtime:ro --workdir /usr/share/bcc/tools zlim/bcc ./execsnoop

Hi. I tested your case and was indeed able to reproduce. $ minikube start --driver=kvm

...Also, please be aware than "bcc based" eBPF tools (also known as "standard") are a bit old and are not the more recent way to interact with eBPF. I hope it solves your problem, otherwise feel free to ping. Best regards. |

Thanks @eiffel-fl, you are right, the proposed docker image is working as expected. Sorry for bothering you, but there are a lot of old info about eBPF and I am lost ... I will take a look to CO-RE tools. Thanks again! :) |
You are welcome :).
No problem, it is a bit normal to be lost when learning eBPF. |
Hi.
This PR permits using
minikube5.10 kernel to develop eBPF related feature.It follows #12707.
I use it as my daily driver and I know developers from Polar Signals use it too.
I was able to build the images and run them:
The implementation of this feature is not perfect (particularly the backporting of upstream buildroot patch) but I think this is the only solution we have since some upstream patches are not part of last buildroot LTS.
Best regards and thank you in advance.
