So I have been digging into this and it seems that an option was added a
decade ago or so to strip the kernel/vmlinux when it's too big, this was
done for at least the routerstationpro according to bug #3515 [0], and
persists with the edgerouter, although I am not sure if it would still
actually be required as the edgerouter also uses the
KERNEL_ALT_IMAGETYPE to create a smaller binary kernel image.

The change I proposed causes the all kernels to be stripped all the time
as part of the split_and_strip_files(). As I see it there few different
options:

1) Set KERNEL_IMAGE_EXTRA_STRIP_SECTIONS = "" in create_spdx.bbclass
- This solves the problem with create_spdx.bbclass is in use, but not
the general case


I don't think I like this as it is a side effect that isn't obvious or expected.



2) Remove the KERNEL_IMAGE_EXTRA_STRIP_SECTIONS from edgerouter.conf
- Will solve the edgerouter case but may not solve other usages
unknown to me.
- Does anyone know of other machines/layers usage of this variable?

3) deprecate the kernel.bbclass:do_strip function in favor of using the
split_and_strip_files() of package.bbclass


I know Bruce has said he doesn't like this, however stepping back, these issues
were from a time our stripping code was young and evolving. If we can
standardise and have it all work together well in one set of functions, I think
that is worth looking at. I'd prefer the kernel wasn't a special case if it no
longer needs to be.

That said, I don't remember the details of why we did this.


There's a middle ground of debug being possible, and some sections
removed to keep the footprint a bit lower. There were also some
unwinders, etc, that didn't work when everything was stripped and
split into debug. The stripping was too aggressive, and removed some
sections that were required.

While I can't exactly point to the use cases for it now, with the 5K
options in the kernel, they haven't all been removed, and I'd be very
hesitant to remove the capability completely.



I think this makes the most sense after thinking about it also, having 
one place where the striping occurs in runstrip() in lib/oe/package.py, 
seems reasonable. The one neck to ring as it were.


We can extend the is_elf() types to add vmlinux and use the 
KERNEL_IMAGE_EXTRA_STRIP_SECTIONS there. So this could deprecate the 
do_strip() from the kernel.bbclass and keep the behavior.

stripped and extended package data would not be av

If we can simplify and stop the kernel being a special case for this code (or
handle kernels generically) that would be worth a bit of effort IMO...

I recall when we added that! It was used for some other boards as
well, but most of them aren't around anymore.

Having some way to have a custom set of sections to strip (along with
skipping stripping (but that can be done via the standard inhibit)) is
something I'd suggest we preserve. But I suppose if you inhibit stripping,
you'll stop both the packaging one and the kernel custom one ?

What are you considering the general case in this instance ? Meaning a
non-spdx user of that same board, will run into issues with the already
stripped ? If they can inhibit the do_package stripping, there is a way around
it.

See above. There are some machines, and even if not common, it is
something I'd like to preserve.

I'd prefer to not do #3.

#4 is what came to mind for me. We already have special cases for the
kernel, so this isn't making things more complex .. or maybe there's a
more elegant "co-operative" section removal flag that the kernel bbclass
can set, and then the packaging not error or automatically inhibit the
QA check ?

But #1 is my second choice.

https://autobuilder.yoctoproject.org/typhoon/#/builders/111/builds/2507/steps/11/logs/stdio

So I have been digging into this and it seems that an option was added a 
decade ago or so to strip the kernel/vmlinux when it's too big, this was 
done for at least the routerstationpro according to bug #3515 [0], and 
persists with the edgerouter, although I am not sure if it would still 
actually be required as the edgerouter also uses the 
KERNEL_ALT_IMAGETYPE to create a smaller binary kernel image.


The change I proposed causes the all kernels to be stripped all the time 
as part of the split_and_strip_files(). As I see it there few different 
options:


1) Set KERNEL_IMAGE_EXTRA_STRIP_SECTIONS = "" in create_spdx.bbclass
  - This solves the problem with create_spdx.bbclass is in use, but not 
the general case


2) Remove the KERNEL_IMAGE_EXTRA_STRIP_SECTIONS from edgerouter.conf
  - Will solve the edgerouter case but may not solve other usages 
unknown to me.

  - Does anyone know of other machines/layers usage of this variable?

3) deprecate the kernel.bbclass:do_strip function in favor of using the 
split_and_strip_files() of package.bbclass


4) Change error to warning in packaging.bbclass for the kernel only
  - This would explain that a kernel image (vmlinux) is already 
stripped and extended package data would not be available for for SPDX 
creation.

I tried these and have not been able to reproduce the failure.




selftest failure in linux-yocto:

(file truncated makes it sound like a race?)

stap kernel module failure:

(race/intermittent?)

another kernel module race:
https://autobuilder.yoctoproject.org/typhoon/#/builders/63/builds/4480/steps/16/logs/stdio

Might need to try this on the AB once I resolve the kernel stripping 
issue above.


Sau!
