BPF Linux ELF objects are generated with kernel-selftests with
>= 4.18 kernel and when clang is enabled which packages BPF objects
into packages, therefore recongnise this as a valid ELF target
Add a selftest for BPF
Do not flag BPF objects in target, since they pretty much will be ok for
most of kernels architectures we care do support BPF

Some allarch packages rdepends non-allarch packages. when multilib is
used, it doesn't expand the dependency chain correctly, e.g.
core-image-sato -> ca-certificates(allarch) -> openssl
we expect dependency chain for lib32-core-image-sato:
lib32-core-image-sato -> ca-certificates(allarch) -> lib32-openssl
it should install lib32-openssl for ca-certificates but openssl is still
wrongly required.
Only enable allarch when multilib is not used to fix the issue.

kernel-fitimage.bbclass replaces an occurance of "fitImage" in
KERNEL_IMAGETYPE_FOR_MAKE by an image type that is buildable for the
architecture (such as zImage). The kernel-fitimage.bbclass packs that
image as sub-image in a flattened image tree image (fitImage) and
deploys this fitImage along with the image tree source file (.its).
kernel-fitimage.bbclass does not alter KERNEL_IMAGETYPES, which thus
also contains "fitImage", which kernel.bbclass will also deploy
redundantly with different naming.
The result is a dual deployment with slightly different naming,
each with a set of symlinks.
The solution chosen is to have fitImage deployment be handled by
kernel-fitimage.bbclass, and have kernel.bbclass ignore fitImage
types during deployment.

By default the devicetree class adds padding to the generated .dtb

.dtbo files, which is not useful.
Don't apply padding to the overlay devicetrees.
To achieve this:
* move "-p ${DT_PADDING_SIZE}" to a new variable, DTB_BFLAGS (B for
"base")
* add "-p 0" to DTC_OFLAGS to disable padding for overlays

It occurs because do_stash_locale is not recognised as a setscene task

Currently, a dependency on any -native recipe will pull in
all dependencies of that -native recipe in the recipe
sysroot. This behaviour might not always be wanted, e.g.
when that -native recipe depends on build-tools that are
not relevant for the current recipe.
This change adds a SSTATE_EXCLUDEDEPS_SYSROOT variable,
which will be evaluated for such recursive dependencies to
be excluded. The idea is similar to
http://lists.openembedded.org/pipermail/openembedded-core/2018-January/146324.html
except that the list is not hard-coded anymore.
SSTATE_EXCLUDEDEPS_SYSROOT is evaluated as two regular
expressions of recipe and dependency to ignore, e.g. in
the above flex-native / bison-native use-case, one would
specify
SSTATE_EXCLUDEDEPS_SYSROOT = ".*->(flex|bison)-native"
in layer.conf.
The existing special handling of "-initial" as well as
"base-passwd" and "shadow-sysroot" could also be
streamlined:
SSTATE_EXCLUDEDEPS_SYSROOT += "\
.*->.*-initial.* \
.*(base-passwd|shadow-sysroot)->.* \
"

When invoked in this task, cve-check-tool attempts re-download of the CVE DB
if the latter is older than certain threshold. While reasonable for a
stand-alone CVE checker, this behavior can cause errors in parallel builds
if the build time is longer than this threshold:
* Other tasks might be using the DB.
* Several packages can start the download of the same file at the same time.
This check is not really needed, as the DB has been downloaded by

The DB will be at most (threshold + build_time) old.

This turns out to be because the automatic moving of the -dbg package to
the beginning of the package list is disabled in that case, so the
python3-gpg packages that the recipe prepends to PACKAGES ends up before
the -dbg package.
It's not clear why the "and not split_source_package" was added when
debug-with-srcpkg was introduced. Presumably the intention was to
prevent the -dbg package to end up before the -src package, which we of
course need to. But at the same time, we still need -dbg packages to end
up before all other packages.
Using list.insert(0, ...) also means that if there happens to more than
one -dbg package, their relative ordering gets inverted in the new list.
This tries to fix these issues by sorting the packages by (priority,
original position), where priority is 10 for -src, 30 for -dbg and 50
for everything else. That guarantees that packages of the same "type"
preserve their relative ordering, while also ensuring that -dbg always
preceed other packages. This scheme is also quite extensible, and,
should the need arise, one could even expose the priorities as a knob
the recipe author could use to ensure specific orderings of packages
instead of the somewhat fragile and coarse-grained method of "prepend or
append, and ensure you do that in a proper order".
Probably the autodebug condition needs to stay, but I think the
split_source_package condition in the preceding elif should be removed,
so that that logic applies to all packages called -src, not just the one
we might have created a few lines above.

Currently if you build qemux86 and then generic86, the latter will
remove all of the former from deploy and workdir. This is because
qemux86 is i586, genericx86 is i686 and the architctures are compatible
therefore the sstate 'cleaup' code kicks in.
There was a valid reason for this to ensure i586 packages didn't get into
an i686 rootfs for example. With the rootfs creation being filtered now, this
is no longer necessary.
Instead, save out a list of stamps which a give machine has ever seen in
a given build and only clean up these things if they're no longer
"reachable".
In particular this means the autobuilder should no longer spend a load of time
deleting files when switching MACHINE, improving build times.
