[PATCH 0/4] kernel/kernel-yocto: consolidated pull request

[Bruce Ashfield]

From: Bruce Ashfield <bruce.ashfield@gmail.com>

Hi all,

This is a resend of the v5.4 stable bump to v5.4.38, plus a new -stable
bump to v5.4.40.

The extra changes to make these pass the AB tests are the kernel
reproducibility commits.

The issue we had on the last submission was that IKHEADERS was switched
to a module, and hence was failing reproducibility tests as we didn't
have the timestamp variables exported for the module build. It has
always been a problem, just one we hadn't hit.

I've left the fix as two commits on purpose, since the copy of the
reproducibility export fixes the problem, and is definitely safe for dunfell,
and the second commit is my effort to remove the duplication of logic and
create a common python routine they can call. I've used the techniques for
subprocess running that I've done in other kernel build elements, but if they
aren't the right ones to use, point me in the right direction.

All said, these are green on the AB and should be ok for master and
dunfell.

Cheers,

Bruce

[PATCH 3/4] kernel/reproducibility: kernel modules need SOURCE_DATE_EPOCH export

[Bruce Ashfield]

From: Bruce Ashfield <bruce.ashfield@gmail.com>

If CONFIG_IKHEADERS is set to =m, then reproducibility issues creep
into the modules build, since the variables we are setting for the
main kernel build are not present.

Since the source code must be available for a possibly git query
on the timestamp, there didn't seem to be an easy way to move the
environment variable setting to a common routine. As such, we
duplicate the block of code that exports the required variables for
reproducible builds. There is a maintenance risk to this, but any
issues should be easy enough to catch.

[PATCH 4/4] kernel/reproducibility: factor kernel source epoch for common use

[Bruce Ashfield]

From: Bruce Ashfield <bruce.ashfield@gmail.com>

Rather than duplicating the code to generate the kbuild environment
variable: KBUILD_BUILD_TIMESTAMP, we can factor the checks into a
python function and call it from the main image and kernel module
do_compile routines.

All paths have been checked and the timestamp is identical to the
previous shell variant.

Hah.

Of course after my send, I see that I'm not actually *using* the env.
I'll do an incremental patch to use env while this sits on the list.

Is there something special about the kernel that it can't use the 
SOURCE_DATE_EPOCH guessing code from classes/reproducible_build.bbclass? 
If so, is it possible there is some minor change we could make to the 
code to make it work? It seems a little unfortunate to replicate the 
logic to calculate the SDE when that class does it already.

That's where it is getting the SOURCE_DATE_EPOCH from in the first
line. Only if it isn't set is it falling back and querying the top git
commit and finally the timestamp.

Or at least that's what I understood it to be doing :D

.. or maybe that isn't what you are asking ? That python code is just
a direct replacement of the existing logic that is currently in the
kernel.bbclass that follows the kernel's guidelines for reproducible
builds. I wasn't looking to change the logic, or move it to another
class, just to avoid cutting and pasting the block of code into the
kernel module build phase (which is what I did in the first patch).

I think this triggers something here:

https://autobuilder.yoctoproject.org/typhoon/#/builders/47/builds/1914

which is nodistro rather than poky.

In that case, just drop my effort at factoring out the source date
epoch into a python function.

It looks like the git check went nuts, and since we don't need it, and
I won't have time to work on it again for a while, if you toss it in
the bin, all should be well.

I did tweak the python code to handle the git return code more
gracefully. I did test all the conditional paths before, and they
worked, so I'm not sure how to trigger the failure here.

I can try an AB run against the fixed up routine, but what target
should I be running ? Obviously quick doesn't hit it, or I would have
seen it.

You need to push a plain oe-core branch to oe-core-contrib and point
the build at that. This is the target:

https://autobuilder.yoctoproject.org/typhoon/#/builders/47

(qemuarm-oecore)

Not setting a DISTRO would also do it.

Cheers,

Richard

My local builders are running out of space, so I tried to push to
oe-core-contrib, I don't have access. I assume a github fork of
oe-core would work as well.

But when I checked out that target on the AB, it didn't offer me the
ability to schedule one. Does something need to be granted for that ?

Sorry for the noise, I have this part figured out. I'll try the github
fork of oe-core route.
