Steve reported a build issue with commit 62089b804895 ("kbuild: rpm-pkg:
Generate debuginfo package manually") on RHEL9, which has an older
version of RPM than what I tested. Turns out that RPM 4.20.0 fixed an
issue with specifying %files for a -debuginfo subpackage.
The first patch restricts the new -debuginfo package generation process
to CONFIG_MODULE_SIG=y and RPM >= 4.20.0 to ensure it is actually
necessary and working. The second patch restores the original -debuginfo
package generation process from commit a7c699d090a1 ("kbuild: rpm-pkg:
build a debuginfo RPM") when CONFIG_MODULE_SIG is disabled to keep the
-debuginfo package around for older versions of RPM.

Commit 62089b804895 ("kbuild: rpm-pkg: Generate debuginfo package
manually") moved away from the built-in RPM machinery for generating
-debuginfo packages to a more manual way to be compatible with module
signing, as the built-in machinery strips the modules after the
installation process, breaking the signatures.
Unfortunately, prior to rpm 4.20.0, there is a bug where a custom %files
directive is ignored for a -debuginfo subpackage [1], meaning builds
using older versions of RPM (such as on RHEL9 or RHEL10) fail with:
Checking for unpackaged file(s): /usr/lib/rpm/check-files .../rpmbuild/BUILDROOT/kernel-6.19.0_dirty-1.x86_64
error: Installed (but unpackaged) file(s) found:
/debuginfo.list
/usr/lib/debug/.build-id/09/748c214974bfba1522d434a7e0a02e2fd7f29b.debug
/usr/lib/debug/.build-id/0b/b96dd9c7d3689d82e56d2e73b46f53103cc6c7.debug
/usr/lib/debug/.build-id/0e/979a2f34967c7437fd30aabb41de1f0c8b6a66.debug
...
To workaround this, restrict the manual debug info package creation
process to when it is necessary (CONFIG_MODULE_SIG=y) and possible (when
using RPM >= 4.20.0). A follow up change will restore the RPM debuginfo
creation process using a separate internal flag to allow the package to
be built in more situations, as RPM 4.20.0 is a fairly recent version
and the built-in -debuginfo generation works fine when module signing is
disabled.

Commit 62089b804895 ("kbuild: rpm-pkg: Generate debuginfo package
manually") effectively reverted commit a7c699d090a1 ("kbuild: rpm-pkg:
build a debuginfo RPM") but the approach it took is not safe for older
RPM releases. Restore commit a7c699d090a1 ("kbuild: rpm-pkg: build a
debuginfo RPM") for the !CONFIG_MODULE_SIG case to allow more
environments and configurations to take advantage of the separate debug
information package process.

Yeah, I had similar issue on Fedora 42 (RPM version 4.20.1) and this
series fixed my issue.

Thanks for testing! I find that a little odd though since I tested
62089b804895 in Fedora 42 during my investigation of the problem and it
worked fine without these changes. Nevertheless, I will add your tags to
this series when I apply it.
Cheers,

mmm, that it's odd indeed.
Without this series applied, I had issues on Fedora 42 (RPM version
4.20.1), but it worked on Fedora 43 (RPM version 6.0.1).
I just retried on Fedora 42 to build commit cee73b1e840c ("Merge tag
'riscv-for-linus-7.0-mw1' of
git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux") and I have
the following errors:

Okay interesting! I have not seen that error yet... I wonder if adding
'AutoReqProv: no' to the kernel-debuginfo subpackage (like the
kernel-devel subpackage) would avoid that for rpm 4.20.0... Probably not
that big of a deal if it is resolved with rpm 6.0.1 but it would be good
to avoid as many corner cases as possible.
Cheers,
Nathan

Oh, yeah, I just tried the following change on top of commit
cee73b1e840c ("Merge tag 'riscv-for-linus-7.0-mw1' of

this series applied:

This package provides debug information for the kernel image and modules from the

And I'm able to generate RPMs too without errors!
Thanks,

Great, thanks for confirming! Does it still work with:
AutoReq: 0
AutoProv: 1
as I notice that is what the %_debuginfo_template in /usr/lib/rpm/macros
uses by default. I suspect that the automatic requires is where things
explodes and I think we do want the automatic provides because I believe
that is how the "this package provides this debug build ID" generation
happens.
Cheers,
Nathan

Yep, I tried this (compared to the previous email, just to be sure I get
you):

Oh I see, I also have:
# Template for debug information sub-package.
%_debuginfo_template \
%package debuginfo\
Summary: Debug information for package %{name}\
Group: Development/Debug\
AutoReq: 0\
AutoProv: 1\
%description debuginfo\
This package provides debug information for package %{name}.\
Debug information is useful when developing applications that use this\
package or when debugging this package.\
%files debuginfo -f debugfiles.list\
%{nil}
So I guess I tested the right thing and it works ;-)
Thanks,
Stefano

Thanks!
[1/2] kbuild: rpm-pkg: Restrict manual debug package creation

Please look out for regression or issue reports or other follow up
comments, as they may result in the patch/series getting dropped or
reverted. Patches applied to an "unstable" branch are accepted pending
wider testing in -next and any post-commit review; they will generally
be moved to the main branch in a week if no issues are found.
Best regards,
