Latest LinuxKit kernel headers are not published

[farhadh]

Description

The latest LinuxKit kernel headers for kernel 6.6.22 are not available on Docker Hub. The latest one available is 6.6.13. This causes malfunctions in the building of kernel modules against the latest Docker desktop version.

Reproduce

docker pull linuxkit/kernel:6.6.22-build
docker pull linuxkit/kernel:6.6.22

@farhadh the information about the kernel and the patches applied to it are all in the VM. You can try docker run --privileged --pid=host --rm -it justincormack/nsenter1 /usr/bin/tree /src
Is that enough for your use case? Can you give us more details about what you're trying to achieve? Maybe we can make things better

[farhadh]

@dgageot Thanks for your attention. I need the Linux kernel GTP tunneling module in my LinuxVM kernel for which I need the headers to compile its C code.

Hi, i want to run eBPF & perf tools, they also require headers

docker run --privileged --pid=host --rm -it justincormack/nsenter1 /usr/bin/tree /src
setns:mnt: Invalid argument
