thanks for the report.can you try "bpftune -ds" (should provide more debug info)? can you also confirm you're using latest "main" branch (there were some bugs impacting behaviour on ubuntu that are hopefully fixed now)? can you also provide info on which kernel you're using (uname -r) - i've been testing on an ubuntu 22.04 image using a 5.15 kernel.

thanks for the report.can you try "bpftune -ds" (should provide more debug info)? can you also confirm you're using latest "main" branch (there were some bugs impacting behaviour on ubuntu that are hopefully fixed now)? can you also provide info on which kernel you're using (uname -r) - i've been testing on an ubuntu 22.04 image using a 5.15 kernel.

thanks for the additional info! the problem is

bpftune: libbpf: Unsupported BTF_KIND:19 bpftune: libbpf: loading kernel BTF '/sys/kernel/btf/vmlinux': -22 bpftune: libbpf: failed to find valid kernel BTF

The reason for this is the toolchain (libbpf+bpftool) used to build bpftune doesn't know about BTF_KIND_ENUM64 which is in the kernel BPF Type Format information (BTF) that is embedded when the kernel was built; the toolchain used to build the kernel BTF (pahole+libbpf) is newer than the toolchain used to build bpftune. To get libbpf enum64 support you would need a libbpf version 1.0.0 or later. Not sure if that's packaged for ubuntu yet; alternatively you could try building libbpf from source from github.com/libbpf/libbpf.

The real issue here is that Ubuntu shouldn't build BTF for a 5.15 kernel with such new tools, or if they do they should omit the problematic BTF information.

[alan-maguire]

trying to solve this upstream so future BTF generation will not trip up like this; see https://lore.kernel.org/bpf/20230720201443.224040-1-alan.maguire@oracle.com/

[alan-maguire]

from the bpftune side https://github.com/oracle/bpftune/pull/54 merged a "no BTF" mode of operation which we should fall back to when BTF is missing or invalid (from bpftune's perspective). it's not ideal (because we don't get the automatic fixing of kernel data structure offsets so may be reading bad data), but it's the best we can do under the circumstances.

[alan-maguire]

now that we have "no BTF" mode of operation, closing this issue. we still have issue 37 open which covers the same area, so we can track any further problems there if needed.
