Public bug reported:
OS: Ubuntu Server LTS 24.04, 6.8.0-1004-raspi
The OS is missing support for BTF which is needed in order to use XDP.
BTF is compiled into the x86 Ubuntu kernel but not on the raspi which is
missing the directory /sys/kernel/btf.
As a result, I am unable to use XDP AF_XDP sockets because my BPF
program fails to load with errors:
BPF program load failed: invalid argument.
btf_vmlinux is malformed
Is BTF intentionally removed and can it be added?
