This bug is awaiting verification that the linux-lowlatency-
hwe-6.11/6.11.0-1007.7~24.04.1 kernel in -proposed solves the problem.
Please test the kernel and update this bug with the results. If the
problem is solved, change the tag 'verification-needed-noble-linux-
lowlatency-hwe-6.11' to 'verification-done-noble-linux-lowlatency-
hwe-6.11'. If the problem still exists, change the tag 'verification-
needed-noble-linux-lowlatency-hwe-6.11' to 'verification-failed-noble-
linux-lowlatency-hwe-6.11'.


If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.


See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Title:
  generate and ship vmlinux.h to allow packages to build BPF CO-RE

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Noble:
  Fix Committed

Bug description:
  A vmlinux.h header generated from a kernel build with bpftool is needed to 
build and ship BPF CO-RE programs. We are looking to ship these in the next 
version of systemd.
  vmlinux.h being generated depends on the kernel version, architecture and 
kconfig. There are some vague promises of backward compatibility, but it is 
hard to gauge.

  We definitely do not want this file to be generated from the kernel
  running the build machine when building a package though, as very
  often these are very old and stable kernels building packages for the
  bleeding edge.

  In Fedora and now Debian we generate vmlinux.h at kernel package build
  time, and ship it with the other kernel headers (_not_ UAPI, the
  internal headers): https://salsa.debian.org/kernel-
  team/linux/-/commit/ac6f7eda4c3e8b0d0db20ad4bb8236371cf8d38e

  Please consider doing the same in Ubuntu's linux-headers.
