[Buildroot] [PATCH 0/3] Add first-class support for all active upstream Linux versions

[Buildroot] [PATCH 0/3] Add first-class support for all active upstream Linux versions

[Titouan Christophe via buildroot]

Currently we have many configs based on active upstream Kernel versions.
However, they are all using a custom kernel version string, and must therefore
be updated individually. Since there are many security fixes landing each week
in Linux, and Buildroot contains scripts to automate these version bumps,
having an option to follow the upstream releases automatically helps to:

- Reduce the number of individual patches to update each and every board
- Get frequent security updates on boards that don't receive patches frequently

This idea had already been submitted a while ago in
https://patchwork.buildroot.org/project/buildroot/patch/20241108231236.2838-1-git@jdknight.me/

The script utils/bump-stable-kernel-versions remains unchanged, because its
key regular expression that perform the updates also matches these new
symbols defaults.

[Buildroot] [PATCH 1/3] linux: always select host-uboot-tools for mips

[Titouan Christophe via buildroot]

Since Buildroot commit 40e266ccb9 [1], host-uboot-tools was always selected
for the latest Linux kernel. This change is intended for autobuilders, and
was introduced in Buildroot while the latest kernel was 6.12.

However, further investigation seem to indicate that itb images were
generated for mips for a much longer time. Linux commit eed0eabd12 [2]
seem to enable that image format, and was released in Linux 4.9.

This version being EOL for quite some time, we can therefore assume
any "not so old" Linux for mips will need host-uboot-tools to finalize
this image, and therefore we should select it when building Linux.

[Buildroot] [PATCH 2/3] linux: add first-class support for all upstream linux versions

[Titouan Christophe via buildroot]

Add new KConfig symbols for all actively supported longterm versions of the
Linux kernel. This makes it easier for individual configs to follow updates
of their kernels, without having to frequently update them. This should
generally improve the security of the target systems, which receive frequent
security updates while preserving a stable feature set.

So I moved it outside the choice and committed, thanks.

When we do this then we also need to ensure the hashes for all these
versions are available, so I added the version symlinks like we have for
the linux-headers package:

lrwxrwxrwx 1 peko peko    11 Oct 11 15:08 5.10.271 -> before-6.17

[Buildroot] [PATCH 3/3] configs: update defconfigs with custom versions to BR2_LINUX_KERNEL_LATEST_X_Y

[Titouan Christophe via buildroot]

Update all defconfigs that are using a custom Linux version based on a
longterm supported Linux version so they use the newly introduced symbols.

We already see from this diff that using that feature updates quite a bunch
of disparate kernel versions accross the tree.

This change was automated with the following Python script:

    import re
    from subprocess import check_output

    MAINTAINED_VERSIONS = {
        "6.18": "BR2_LINUX_KERNEL_LATEST_6_18=y",
        "6.12": "BR2_LINUX_KERNEL_LATEST_6_12=y",
        "6.6": "BR2_LINUX_KERNEL_LATEST_6_6=y",
        "6.1": "BR2_LINUX_KERNEL_LATEST_6_1=y",
        "5.15": "BR2_LINUX_KERNEL_LATEST_5_15=y",
        "5.10": "BR2_LINUX_KERNEL_LATEST_5_10=y",
    }

    LINUX_VERSION_LINE = re.compile(r'(configs/[^:]+):(BR2_LINUX_KERNEL_CUSTOM_VERSION_VALUE="(\d\.\d{1,2})(?:\.\d+)?")$')

    findcmd = ["git", "grep", "BR2_LINUX_KERNEL_CUSTOM_VERSION_VALUE="]
    custom_version_configs = check_output(findcmd).decode()

    for line in custom_version_configs.splitlines():
        if (m := LINUX_VERSION_LINE.match(line)) and m[3] in MAINTAINED_VERSIONS:
            content = open(m[1]).read()
            with open(m[1], "w") as out:
                out.write(content.replace(m[2], MAINTAINED_VERSIONS[m[3]]).replace('BR2_LINUX_KERNEL_CUSTOM_VERSION=y\n', ''))
            print(m[1], m[2], "->", MAINTAINED_VERSIONS[m[3]])

Thanks for including the script!

Please check that the defconfigs are still minimal, E.G. for
visionfive2_defconfig the BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_6_18=y
line gets dropped my make savedefconfig.

Oh you are right !
I had performed that in a first pass, identified an issue that I fixed 
in the python script, and then used that fix immediately without 
re-processing the defconfigs.

Will send a v2 of this patch.

This is a significant policy change for Buildroot. The configs/

according to adding-board-support section in Buildroot manual

Automatic update of the kernel component without actual hardware test
risks introducing regressions that make the system unbootable.

For this reason adding-board-support section also says:

If we intend to change this policy I think we should discuss the
motivation on the list. In case such discussion did take place, this
comment should reference that discussion. In any case, the manual should
also update to reflect the current policy.

Thank you for raising that concern ! I am currently preparing a v2 of 
this patch (with many other fixups), and I will update the manual 
accordingly.

This is a tradeoff, really.
On one hand (A), there is the risk of breaking the functionality of a 
board by bumping from one patch version to another.
On the other (B), any new Linux patch version brings a handful of 
security fixes, and this happens on a weekly basis.

Now onto practical considerations and my opinions:
- From my understanding, (A) is not very frequent when bumping from one 
patch version to another. It can certainly happen on a specific board 
from time to time, but this is definitely far from the general case. If 
you (or anyone else) have some recent examples of such situations, I'd 
be glad to read about them. On the contrary bugs in core components that 
would affect all boards, such as the ext4 corruption introduced in linux 
6.1.64, would be more easily controllable tree-wise with such a mechanism.
- We see that many boards in the Buildroot tree are updated very 
infrequently, and are using old kernel versions, sometimes lagging more 
than 200 versions behind (see for example 
configs/minnowboard_max_defconfig). This is not a good sign for newcomers.
- Each kernel version bump for a single board is a patch that has to be 
reviewed and applied by a maintainer. I believe their time is better 
invested into patches that need actual effort, especially given the 
current patchwork backlog
- From my LTS steward perspective, it is practically unfeasible to apply 
linux version bumps on the maintained branches, because their minor 
kernel versions differ from master. On the other hand we try to deliver 
on the premise of improved security, hence getting security updates in 
due time.

With all that being said:
- Linux kernel versions are still stated explicitly in Buildroot and are 
bumped with patches that follow the usual review process. They would 
only be declared in a central place.
- It is still possible to pin a particular linux kernel version to a 
board with BR2_LINUX_KERNEL_CUSTOM_VERSION if needed

I indeed brought the discussion in person with the maintainers that were 
present at the Buildroot Developers meeting after ELC, but I should be 
more verbose in writing, I will pay more attention to that in v2. If you 
have anything else to bring to the discussion, please let me know as well.

The basic question is what are these deconfigs meant to achieve? My
understanding is that defconfigs demonstrate hardware working with a Buildroot
generated image. For many users this is the first Buildroot step. Hardware
bring-up is non trivial, and defconfigs preserve a known working state for a
given target system. defconfig is only an enabler for new users.

I have seen cases where trivial changes broke essential functionality. In one
case I remember a removed print broke two different network PHYs on the same
board because of missing proper initialization delay.

The current suggestion does not even preserve the original user tested
kernel version. By the time a defconfig reaches master branch, the
kernel is different. If this commit is accepted, I think we should
provide a way to preserve somehow the information of user tested kernel
version.

I agree we should remove unmaintained defconfigs after a given time of
inactivity. But I'm not sure blind kernel version updates make the state of
these platforms much better.

This commit only saves stable kernel version updates. These patches are
trivial. We can think of a fast track mechanism that allows contributor to
assert some newer kernel version works on a given hardware, and automatically
generate a matching commit.

The point here is to preserve the vital information contributors provide
of tested software.

Indeed, this discussion should address the intended role of in-tree 
defconfigs.
My personal opinion on this role:
- They provide (as you say) a first entry into Buildroot for many users.
- However, I believe they should build a somewhat up-to-date system, and 
demonstrate ways for users to keep their boards up to date.
- There could be other packages that are key to the board functioning 
normally (such as firmware blobs, host tools involved in the target 
image finalization, ...), and these packages receive version bumps as 
well, without being set in the  board's config. I would even expect them 
to break less often with up-to-date kernels (but this is speculation)

How frequently have you seen such breakages ? I believe they shouldn't 
happen that often, they are very hardware specific, and should be easily 
fixed by temporarily pinning the kernel to a previous version, until the 
bug is resolved in linux.
We could even argue that this could help unveil such breakages to report 
them upstream, but this is another question :-)

That is indeed a very valid point. Would you mean having an entry in the 
board's README, or a comment in the defconfig; basically a human-written 
note stating "this board was tested successfully on <date> with <kernel 
version>" ? Any other suggestion ?

As Arnout suggested in his reply, maybe we could only start with qemu 
boards for now, as they can easily be tested in the CI. Then add this 
feature for configs where a matching board is available for automated 
testing; although I've never heard of any board farm associated with the 
Buildroot project.

As you said earlier, board bringup is not always trivial, so I would 
find it "sad" that we eliminate defconfigs solely because nobody is 
submitting frequent kernel updates to them; while they could still serve 
as a reference for similar platforms.

Yes indeed, but even looking at the backlog to find trivial patches 
costs some maintainer time, and in any case increases the cognitive 
overhead for them.

Agreed !

  Another way to achieve that is to add a HOWTO to the docs that explains how to 
use a defconfig. Something like:

1. Find the right defconfig.
2. make foo_defconfig; make; deploy
3. It boots? Joy! Now prepare for modification.
    make BR2_DEFCONFIG=<my own defconfig> savedefconfig
4. Switch from the custom kernel to the corresponding LTS branch and test.
5. Switch to the latest kernel and test.
6. If it works, fixate that and contribute the change.

  Arnout

For the record, I like this direction. Especially if steps

I remember many cases of regression debugging after kernel/U-Boot/TF-A
updates.

Being hardware specific is indeed our problem. Also, we need to preserve
the identity of said "previous version" for version pinning to work. New
user will have hard time finding the known working kernel.

Of course. But you need access to target hardware for bugs to come up,
and a skilled engineer to debug. New users are unlikely to do that.

That is possible. I find the current defconfig method easiest. But if
updated kernel version takes priority, then maybe keep the known working
defconfig somewhere else.

  It was discussed orally during the developer meeting, but you're right that 
it's something that should be discussed in public as well. Consider this the 
start of that discussion :-)

  There are several reasons that we thought this was acceptable.

  The current situation is that defconfigs contain a known-broken kernel 
(because every stable update has bugfixes). Also the assumed testing is 
typically very minimal, i.e. it is tested that the board boots. It's possible 
that e.g. networking is broken and the contributor doesn't notice.

  Similarly, we do already update the toolchain and busybox without testing if 
it still boots. Of course, you can argue that that doesn't mean we should be 
making it even worse.

  The other thing is that we can kind of trust the kernel stable process to 
avoid breaking things - or at least, that breakage is going to get fixed 
relatively quickly.

  We also have to face the fact that most boards are rarely updated. It's not 
super easy to update the board's kernel because you also have to update the hash 
file. And because of this we have different hash files all over the place. So 
users are facing a very old kernel. Not exactly the best out-of-the-box 
experience either.
On the other hand, in the current situation at least the user gets some info 
about which kernel version is supposed to work, and it's relatively easy to 
switch to one of the stable kernel versions. This proposed change takes away 
that information.

  Another benefit we saw is that at some point a stable series goes EOL, so the 
corresponding option is removed from linux/Config.in. We can use that occasion 
to also remove stale defconfigs that still use that very old kernel. But of 
course, it's easy enough to do that without this option as well.


  Now that I've written all of this down, I'm not so sure if this is a good idea 
after all. The arguments in favour are fairly thin, especially since it's rather 
easy for a user to switch to one of the stable kernels.

  I do think we should at least do this for the qemu family - but those do get 
tested of course.

  Arnout

One argument that I believe strengthen the case for this patch is that 
having this mechanism in place for LTS branches would really help in 
keeping boards up to date regarding security fixes in the kernel, which 
are prohibitively complicated to backport otherwise. But of course I'm 
really biased here.
