Bug Description
[Impact]
To continue having BTF enabled in Linux HWE kernels an update to dwarves is required.
v6.3+ kernels require dwarves v1.25 or better.
This bug report is similar to a previous such backport https:/
Similar to before, to minimise changes, dwarves will be built with vendored and statically linked libbpf on releases that have older libbpf (jammy & kinetic). Lunar & Mantic use shared linked libbpf as the one in the archive is the same version as vendored one.
[Test Case]
* Rebuild given series GA kernel
* On Jammy, rebuild GA, HWE, and Mantic kernels
[Where problems could occur]
Currently in jammy-lunar we ship cherry-pick from development pre-release 1.25 to address new BTF types. The upstream approach since this cherry-pick has changed to a more conservative one. This backport will align Ubuntu BTF with now released versions of BTF.
Currently in lunar we have a BTF bug which leads to generating duplicate BTF information. This backport will address it. See https:/
