Kernel and RPM related bbclass changes

Kernel and RPM related bbclass changes

[Zoltan Boszormenyi]

I have been carrying some forked bbclass recipes and I think
these can be beneficial to others, not to mention that I could
get rid of the private forks of these.

Please, review.

[PATCH 1/6] package_rpm.bbclass: Handle posttrans scriptlets

[Zoltan Boszormenyi]

From: Zoltán Böszörményi <zboszor@gmail.com>

The "posttrans" scriptlet is the RPM equivalent of the
OPKG "intercept script" concept and probably a cleaner one.

"pretrans" also exists in RPM but there's no equivalent
for it in OPKG.

This needs to be better documented and tested.

What does this posttrans thing really do?
Who would want to use it?
Can there be examples?
Can the Postinst test in meta/lib/oeqa/selftest/cases/runtime_test.py be
extended to regression-check that it works?

Re: [OE-core] [PATCH 1/6] package_rpm.bbclass: Handle posttrans scriptlets

[Zoltan Boszormenyi]

It's documented at www.rpm.org, Red Hat and SuSE.

https://docs.fedoraproject.org/en-US/packaging-guidelines/Scriptlets/
https://en.opensuse.org/openSUSE:Packaging_scriptlet_snippets
https://rpm-packaging-guide.github.io/

It's available since RPM 4.4. RPM 4.16.1.3 is in Hardknott.

A short Google search showed that *maybe* dpkg also supports it,
or at least there are(were?) plans to implement it:
https://wiki.debian.org/i18n/TranslationDebsProposals

With postinst, the time when the scriptlet runs may depend
on the order of the packages in the upgrade transaction and
may run with the older binaries in place.

The posttrans scriptlet runs at the very end of the
install/upgrade transaction, just like the OPKG "intercept"
scripts.

I successfully tested it long ago with a kernel upgrade
that was running dracut on the new version, plus a dracut
upgrade in the same session. Dissecting the initramfs proved
that with postinst, the old dracut version generated it,
while with posttrans, the new one did.

Who would want to use it? Anyone who needs some finalizer
script to be run at the end of an RPM/DNF transaction.

I started on Angstrom and I know opkg doesn't implement this
and Yocto inherited it. This patch is basically a heads up
that there's another way to do the same thing. Maybe opkg
implements this some day, maybe not. Anyway, Yocto in general
will need more changes before the main package.bbclass can
start to use it for all package formats.

There is a bigger issue here which is how can anyone use this without making
their recipe rpm specific? I'm very reluctant to add functionality like this
unless we have a way to emulate it or fall back on the other package formats.

The intercept pieces are used by both rpm and opkg and actually do something
slightly different, they stack common calls until the end of the transaction.
This means for example we can call "ldconfig" once rather than in every
postinst.

Cheers,

Richard

Indeed. This patch can be dropped.

Full disclosure: I don't use this anymore, since I implemented
another two bbclass recipes to generate the kernel's initramfs
either during the kernel build (and ship it in a subpackage) or
during do_rootfs and move it out of the way in the image postprocess
script so e.g. a squashfs image will have it separately.
They work well for my use limited cases:
* full OS installed on disk
* squashfs for PXE-based remote booted machines

FYI: the dracutsysrootdir feature in recent dracut versions is my work.

I just carried this patch for a couple of years now and I thought maybe
someone sees some value in it.

[PATCH 3/6] kernel-module-split.bbclass: Allow opt-out of split kernel modules

[Zoltan Boszormenyi]

From: Zoltán Böszörményi <zboszor@gmail.com>

For some use cases, a monolithic kernel-modules package containing
all modules built from the kernel sources may be preferred.
For one, download time is shorter and installation time is faster.

Set KERNEL_SPLIT_MODULES="0" for this.

The default is one subpackage per module.

There's still an outstanding issue though. Unless you generate the
provides/rdepends along with the monolithic package, any existing
rdepends on kernel modules break.

While that likely isn't something you hit in your use case, it would
be something that would have to be covered to make this part of core.

About 7 years ago, I was most of the way through a similar change,
that created on large package with all the rprovides generated (I'm
not sure I can track it down now, but I could have a look), since
doing an on target update with thousands of kernel module package is
very painful.

Cheers,

Bruce

Well, yes. In our defconfig, about 1500 kernel-module-* subpackages
were created and had to be upgraded at once. It was *very* painful
with over 50 minutes to download and upgrade the kernel.

That's what my follow up said ;)

See my second reply though, this gap in functionality created by this
commit, should be documented in the commit that it will be restored in
future ones.

That's my preference (others may disagree), since they are related and
anyone that has poked around in this area may notice the issue (like I
did).

I don't normally bisect through oe-core, but it is nice to know that
if you were on this intermediate commit, that the dependencies would
stay valid/consistent.

Ha.

Never mind, I see the next patch in the series.

It would be worthwhile to document that other changes handle that
detail in the commit log, that way if we are looking for issues in the
future, we know there is hope :D

[PATCH 5/6] kernel.bbclass: Use full versions for inter-package dependencies

[Zoltan Boszormenyi]

From: Zoltán Böszörményi <zboszor@gmail.com>

Some Yocto users do use package repositories and sometimes the PR
value is forgotten. Use full versions for inter-package dependencies
for the kernel subpackages.

Can you expand this commit message ? What is the observable problem
with the full versions not being in the rdpends ?

I've run many different package feeds with different kernels and
modules, and haven't run into anything on this front, in my experience
the extended version in the package depends/provides causes issues
with some package managers .. so we'd need the testing for this
documented/provided so we could ensure that there are no hidden
issues.

I will send a new version with the expanded message.

Currently the kernel creates such subpackages:

kernel
kernel-x.y.z
kernel-image-x.y.z
kernel-image-bzimage-x.y.z
kernel-modules-x.y.z

and in the split modules case, a lot of

kernel-module-*-x.y.z

RDEPENDS currently only references the package names.

The issue I observe is this: I have enabled kernel module signing
but I don't provide a key, so the kernel will generate one at
every rebuild.

You get the idea what problem this can make if there's a
rebuild:

x.y.z-r0.0 -> x.y.z-r1.0 (in which case the PR value was duly changed)
or
x.y.z-r0.0 -> x.y.z-r0.1 (where not)

It's actually indifferent, but the same issue occurs if
only the kernel-image-bzimage is upgraded: the modules either
won't work or taint the kernel.

This scenario is currently valid in the package manager because
of the versionless RDEPENDS.

Your second example is similar to the times I've seen some module
issues as well, and honestly, I can't recall if it was solved in a
similar way to this (I don't have access to my old repos from Wind
River any more).

But that does make sense to me, and the details you have in this
follow up, make a nice commit explanation.

While opkg may not handle the situation you describe as well as RPM,
we should make sure that the full version doesn't cause issues with
the package generation or standard image creation.

Cheers,

Bruce

You can bet it doesn't. I have the same patch in a Sumo-based distro
where we still use ipk and opkg and there's no issue in either image
generation or package upgrades. Only that there's no "installonly"
knowledge in opkg (unlike dnf) so old kernel packages have to be
manually cleaned up there.

Kernel related bbclass changes

[Zoltan Boszormenyi]

I have been carrying some forked bbclass recipes and I think
these can be beneficial to others, not to mention that I could
get rid of the private forks of these.

v2:
- drop the package_rpm.bbclass / posttrans patch
- squash the previous patches #3 and #4 together (patch #2 now)
- more verbose commit message for patch #3 (previously patch #5)

[PATCH v2 2/4] Allow opt-out of split kernel modules

[Zoltan Boszormenyi]

From: Zoltán Böszörményi <zboszor@gmail.com>

For some use cases, a monolithic kernel-modules package containing
all modules built from the kernel sources may be preferred.
For one, download time is shorter and installation time is faster.

Set KERNEL_SPLIT_MODULES="0" for this in. The default is one subpackage
per module.

Also, adapt kernel.bbclass to KERNEL_SPLIT_MODULES != "1" case
Extra RDEPENDS and other inter-package references are needed in
this case.

[PATCH v2 3/4] kernel.bbclass: Use full versions for inter-package dependencies

[Zoltan Boszormenyi]

From: Zoltán Böszörményi <zboszor@gmail.com>

If the kernel configuration enables module signing but no key
is provided, then the kernel generates one during the kernel build.

The current runtime-dependency references (with only package names
without full versions) allow mixed package installations from different
rebuilds of the same kernel version.

This does create an issue if the kernel configuration enables module
signing but no key is provided, in which case the kernel generates
the signing key during the kernel build.

Tighten RDEPENDS with the full package version, i.e. use (= ${EXTENDPKGV})
markers for inter-package dependencies.

The kernel will pull in the kernel-modules subpackage of the same
exact version automatically if KERNEL_SPLIT_MODULES="0" is set.
Otherwise the situation is the same as with the old default with
one subpackage per kernel module where they have to be upgraded
manually.

Kernel related bbclass changes

[Zoltan Boszormenyi]

I have been carrying some forked bbclass recipes and I think
these can be beneficial to others, not to mention that I could
get rid of the private forks of these.

v2:
- drop the package_rpm.bbclass / posttrans patch
- squash the previous patches #3 and #4 together (patch #2 now)
- more verbose commit message for patch #3 (previously patch #5)

v3:
- fix commit message for patch #3 (stupid copy&paste&thinko)

[PATCH v4 2/4] Allow opt-out of split kernel modules

[Zoltan Boszormenyi]

From: Zoltán Böszörményi <zboszor@gmail.com>

For some use cases, a monolithic kernel-modules package containing
all modules built from the kernel sources may be preferred.
For one, download time is shorter and installation time is faster.

Set KERNEL_SPLIT_MODULES="0" for this in. The default is one subpackage
per module.

Also, adapt kernel.bbclass to KERNEL_SPLIT_MODULES != "1" case
Extra RDEPENDS and other inter-package references are needed in
this case.

[PATCH v4 3/4] kernel.bbclass: Use full versions for inter-package dependencies

[Zoltan Boszormenyi]

From: Zoltán Böszörményi <zboszor@gmail.com>

If the kernel configuration enables module signing but no key
is provided, then the kernel generates one during the kernel build.

The current runtime-dependency references (with only package names
without full versions) allow mixed package installations from different
rebuilds of the same kernel version.

This creates an issue because then the modules either don't work
or taint the kernel.

Tighten RDEPENDS with the full package version, i.e. use (= ${EXTENDPKGV})
markers for inter-package dependencies.

The kernel will pull in the kernel-modules subpackage of the same
exact version automatically if KERNEL_SPLIT_MODULES="0" is set.
Otherwise the situation is the same as with the old default with
one subpackage per kernel module where they have to be upgraded
manually.

Reverting this commit does solve it, but I would like to understand
more on what should be done in order to use this new mechanism you've
introduced. Do you have any suggestion on what should be adapted in
the BSP layer to have those RDEPENDS properly resolved?

Package manager is set for me to IPK.

Setting KERNEL_SPLIT_MODULES="1" does not solve the issue.

This seems to be the problem.
Is there a "kernel-image-image-5.13.13" built from your kernel recipe?
For me, a kernel-image-bzimage-x.y.z is built.

This is the default.
But setting it to "0" won't change whether the
kernel-image-image-x.y.z subpackage gets built or not.

Yes, it is produced. But for some reasons opkg cannot resolve it
during the do_rootfs(), which is quite odd.

I'm seeing the same issue.  All of the BSPs that I set the kernel to
not be 5.13 (i.e., 5.10, 5.4, etc) fail.  For example,
https://gitlab.com/jonmason00/meta-arm/-/jobs/1544819828
If I set the PACKAGE_CLASS to be rpm instead of ipk, everything works
as expected.  So, there must be some difference in the dep calculation
in ipk.


Thanks,
Jon

Interesting.

Can you both please try setting KERNEL_SPLIT_MODULES="0" in your kernel recipe?
In my testing, it works for both ipk and rpm properly.

I am thinking that probably the full version dependency should
only be used in the KERNEL_SPLIT_MODULES="0" case.
This can be easily tested, unlike the packaging method.

Ross noticed it was failing with unexpanded AUTOINC references. That made me
realise that using the unexpanded version of the variable in these cases might
help. I've sent out that patch for review/testing.

[PATCH v3 2/4] Allow opt-out of split kernel modules

[Zoltan Boszormenyi]

From: Zoltán Böszörményi <zboszor@gmail.com>

For some use cases, a monolithic kernel-modules package containing
all modules built from the kernel sources may be preferred.
For one, download time is shorter and installation time is faster.

Set KERNEL_SPLIT_MODULES="0" for this in. The default is one subpackage
per module.

Also, adapt kernel.bbclass to KERNEL_SPLIT_MODULES != "1" case
Extra RDEPENDS and other inter-package references are needed in
this case.

[PATCH v3 3/4] kernel.bbclass: Use full versions for inter-package dependencies

[Zoltan Boszormenyi]

From: Zoltán Böszörményi <zboszor@gmail.com>

If the kernel configuration enables module signing but no key
is provided, then the kernel generates one during the kernel build.

The current runtime-dependency references (with only package names
without full versions) allow mixed package installations from different
rebuilds of the same kernel version.

This creates an issue because then the modules either don't work
or taint the kernel.

Tighten RDEPENDS with the full package version, i.e. use (= ${EXTENDPKGV})
markers for inter-package dependencies.

The kernel will pull in the kernel-modules subpackage of the same
exact version automatically if KERNEL_SPLIT_MODULES="0" is set.
Otherwise the situation is the same as with the old default with
one subpackage per kernel module where they have to be upgraded
manually.

Re: [OE-core] [PATCH v3 4/4] Support zstd-compressed squashfs and cpio initramfs
