Kernel bug returns on linux-hardened

According to this, everyone using the hardened kernel is receiving these errors at boot, and we just have to wait for an upgrade - correct?

https://bugs.archlinux.org/task/69155

libbpf: Failed to find valid kernel BTF
libbpf: Error loading vmlinux BTF: -3
libbpf: Failed to load object ‘iterators_bpf’
libbpf: failed to load BPF skeleton iterators_bpf: -3
Failed load could be wrong endianess

Re: Kernel bug returns on linux-hardened

According to the bug report, they are warnings, not errors. Is there anything actually broken?

Re: Kernel bug returns on linux-hardened

I just (2202-05-22T15:06-0600) upgraded my server to linux-hardened-5.17.9.hardened1-1, from  linux-hardened-5.17.7.hardened1-1

On reboot, I get exactly those messages after it checks the filesystems:

Starting version 250.5-1-arch
/dev/sda1: clean, 166777/14123008 files, 15012325/56464640 blocks
libbpf: failed to find valid kernel BTF
libbpf: Error loading vmlinux BTF: -3
libbpf: failed to load object 'iterators_bpf'
libbpf: failed to load BPF skeleton 'interators_bpf': -3
failed load could be due to wrong endianness

Typed that in from an image I took of the server's monitor after the reboot failed. There might be a small typo or two.

Re: Kernel bug returns on linux-hardened

Hey

Just wondering is there any changes coming up or does it need manually work on our side?

I've seen that the bug was there before as well:
