Re: [Buildroot] [PATCH v2] package/mdadm: bump to version 4.6

[Julien Olivain via buildroot]

Hi Maxin,

Thanks for the v2. This new 4.6 version is introducing 2 issues.

On 25/04/2026 08:27, Maxin John wrote:

First, it breaks the mdadm runtime test. See:
https://gitlab.com/jolivain/buildroot/-/jobs/14088239652

You can reproduce the issue with the command:

utils/docker-run \
     support/testing/run-tests \
     -k -d dl -o output_folder tests.package.test_mdadm

This new version asks a question and blocks the test.

This commit should make sure the test keep working.
So this can be fixed by passing the answer to the question.
Adding "--bitmap=none" to the "mdadm --create" options should
fix the issue. See:
https://gitlab.com/buildroot.org/buildroot/-/blob/2026.02.1/support/testing/tests/package/test_mdadm.py?ref_type=tags#L72

Also, this new version breaks with toolchains with old kernel headers. 
See:
https://gitlab.com/jolivain/buildroot/-/jobs/14088277312

You can reproduce the issue with the command:

     utils/test-pkg -p mdadm

This is due to mdadm upstream commit 
71574efb077131701b3da874df0045f259ca3448
(in mdadm 4.0) which introduced a usage of MD_DISK_FAILFAST but was also
including the definition. Then upstream commit
f5889f9a1b8753a1472dfef9d025da2bae395239 (in mdadm 4.5) removed the
usage of those local definitions to use the kernel instead.
So mdadm has now a new requirement on Kernel headers >= 4.10.

The bootlin-aarch64-glibc-old has 4.9 kernel headers and is now failing.

Search for "BR2_TOOLCHAIN_HEADERS_AT_LEAST_" for examples.

Could you add this new requirement in Config.in and the explanation in
the commit log please?

Could you send an updated patch addressing those issues,
please?

Best regards,

Julien.

Thanks again for the detailed review and pointers. That was really helpful. I
