Comment 2 for bug 1981574

As you have seen in the above conversations, libbpf was not updated in the SRUs. Instead dwarves-dfsg was SRUed with a vendored copy of libbpf statically linked, such that only it uses updated libbpf as it expects latest one.

The package from -updates was binary copied into build-depends PPA used to build all kernels since forever, and all kernels that we have build for -security pocket have been using dwarves-dfsg from -updates effectively.

However, it means locally users cannot rebuild src:linux package in a local chroot with release & -security suites alone.

The tooling is end-developer targeted one, and the only/primary users of it are people working with kernel bpf. And most likely they are using the up to date version from -updates already.

Please binary copy / release dwarves-dfsg from -updates to -security to allow users to rebuild kernels locally against the -security pocket only.
