Subsequent patches in the series change vmlinux linking scripts to
unconditionally pass --btf_encode_detached to pahole, which was
introduced in v1.22 [1][2].
This change allows to remove PAHOLE_HAS_SPLIT_BTF Kconfig option and
other checks of older pahole versions.

We've had problems in the past because we get pahole version from .config in Makefile.btf pahole-ver := $(CONFIG_PAHOLE_VERSION) and it can be outdated. Specifically the problem is that if "make oldconfig" is not run after updating pahole we don't get the actual pahole version during builds and options can be missing. See [1] for an example, but perhaps we should do pahole-ver := $(shell $(srctree)/scripts/pahole-version.sh) in Makefile.btf to ensure the value reflects latest pahole and that then determines which options we use? Andrii suggested an approach like CC_VERSION_TEXT might be worth pursuing; AFAICT that recomputes the CC_VERSION and warns the user if there is a version difference. Given that the CONFIG pahole version requirements are all pretty modest - it might simply be enough to recompute it in Makefile.btf and perhaps ensure it's not less than CONFIG_PAHOLE_VERSION. Just a thought anyway. Thanks! Alan [1] https://lore.kernel.org/bpf/CAEf4BzYi1xX3p_bY3j9dEuPvtCW3H7z=p2vdn-2GY0OOenxQAg@mail.gmail.com/

Just a thought anyway. Thanks! Yeah, I am aware of the issue. I am not sure version refresh in Makefile.btf would be enough, since there are config dependencies in Kconfig.debug. So we either need to trigger re-config, and maybe even force full kernel re-build, or somehow get rid of the version checks in the kconfig, which may be a challenge. I think the simplest thing we could is to check if the version has changed and fail the build. That's a "panic!" approach though. I'll look into how compiler versions are checked, maybe it's not that hard to add similar behavior for pahole. > > Alan > > [1] https://lore.kernel.org/bpf/CAEf4BzYi1xX3p_bY3j9dEuPvtCW3H7z=p2vdn-2GY0OOenxQAg@mail.gmail.com/ >
