[pve-devel] [PATCH pve-kernel] build: re-enable BTF

Fabian Grünbichler f.gruenbichler at proxmox.com
Mon Jan 30 14:27:19 CET 2023 

but allow discarding BTF information when loading modules, so that upgrades
which are otherwise ABI compatible still work. this allows using BTF
information when matching and available, while degrading gracefully if the
currently running kernel is not identical to the one that module was built for.

in case of a mismatch, the kernel will log a warning when loading the module,
for example:

Jan 30 13:57:58 test kernel: BPF:          type_id=184 bits_offset=4096
Jan 30 13:57:58 test kernel: BPF:
Jan 30 13:57:58 test kernel: BPF: Invalid name
Jan 30 13:57:58 test kernel: BPF:
Jan 30 13:57:58 test kernel: failed to validate module [bonding] BTF: -22

Notes:
    two things that are worth mentioning:
    - BTF information will only be generated if paholes is new enough, for bullseye
      this means the version from backports, where it got split out of the dwarves
      package - it might be worth it to enforce this in d/control.in and upload it
      to our -devel repository
    - this will cause an ABI bump
    
    tested by doing two test builds
    - first with this patch + ABI bump
    - second rebuild with additional package revision bump on top, BTF offsets
      will change
