[PATCH 0/2] kbuild: rpm-pkg: Address -debuginfo build regression with RPM < 4.20.0
Posted by Nathan Chancellor 2 months ago
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.

Applied to

Thanks!

[1/2] kbuild: rpm-pkg: Restrict manual debug package creation
      https://git.kernel.org/kbuild/c/6d6b8b0e28c46
[2/2] kernel: rpm-pkg: Restore find-debuginfo.sh approach to -debuginfo package
      https://git.kernel.org/kbuild/c/ffe9ac1ad56df

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.

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,
Nathan

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

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 
git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux"), so without 
this series applied:

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

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):

diff --git a/scripts/package/kernel.spec b/scripts/package/kernel.spec

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!

I cannot test this properly right now, but the changes look good to me.
