Commit e2c318225a ("kbuild: deb-pkg: add
pkg.linux-upstream.nokernelheaders build profile") changed how
install-extmod-build gets called, making it always rebuild the host
programs below scripts/ if HOSTCC wasn't specified with its full triplet
on the make command line. That is, apparently, needed to fix up commit
f1d87664b8 ("kbuild: cross-compile linux-headers package when
possible") for cross-compiles. However, in the much more common case of
non-cross-compile builds this will lead to unnecessary rebuilding of
host tools including gcc plugins. This, in turn, will lead to a full
kernel rebuild on the next 'make bindeb-pkg' which is unfortunate.
Avoid that by only triggering the rebuild of host tools for actual
cross-compile builds.

By passing an additional directory to run-parts, allow Debian and its
derivatives to ship maintainer scripts in /usr while at the same time
allowing the local admin to override or disable them by placing hooks of
the same name in /etc. This adds support for the mechanism described in
the UAPI Configuration Files Specification for kernel hooks. The same
idea is also used by udev, systemd or modprobe for their config files.
https://uapi-group.org/specifications/specs/configuration_files_specification/
This functionality relies on run-parts 5.21 or later. It is the
responsibility of packages installing hooks into /usr/share/kernel to
also declare a Depends: debianutils (>= 5.21).
KDEB_HOOKDIR can be used to change the list of directories that is
searched. By default, /etc/kernel and /usr/share/kernel are hook
directories. Since the list of directories in KDEB_HOOKDIR is separated
by spaces, the paths must not contain the space character themselves.

The linux-image package currently includes empty hook directories
(/etc/kernel/{pre,post}{inst,rm}.d/ by default).
These directories were perhaps intended as a fail-safe in case no
hook scripts exist there.
However, they are really unnecessary because the run-parts command is
already guarded by the following check:
test -d ${debhookdir}/${script}.d && run-parts ...
The only difference is that the run-parts command either runs for empty
directories (resulting in a no-op) or is skipped entirely.
The maintainer scripts will succeed without these dummy directories.
The linux-image packages from the Debian kernel do not contain
/etc/kernel/*.d/, either.

Stop installing Debian maintainer scripts when building a

Debian maintainer scripts are used for e.g. requesting rebuilds of
initrd, rebuilding DKMS modules and updating of grub configuration. As
all of this is not relevant for UML but also may lead to failures while
processing the kernel hooks, do no more install maintainer scripts for
the UML package.

Since commit f1d87664b8 ("kbuild: cross-compile linux-headers package

linux-headers package, but it fails under certain circumstances.
For example, when CONFIG_MODULE_SIG_FORMAT is enabled on Debian, the
following command fails:

This commit adds a new profile, pkg.linux-upstream.nokernelheaders, to
guard the linux-headers package.
There are two options to fix the above issue.
Option 1: Set the pkg.linux-upstream.nokernelheaders build profile
$ DEB_BUILD_PROFILES=pkg.linux-upstream.nokernelheaders \
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- bindeb-pkg
This skips the building of the linux-headers package.
Option 2: Install the necessary build dependencies
If you want to cross-compile the linux-headers package, you need to
install additional packages.
For example, on Debian, the packages necessary for cross-compiling it
to arm64 can be installed with the following commands:
# dpkg --add-architecture arm64
# apt update
# apt install gcc-aarch64-linux-gnu libssl-dev:arm64

There are two ways of managing separate debug info files:
[1] The executable contains the .gnu_debuglink section, which specifies
the name and the CRC of the separate debug info file.
[2] The executable contains a build ID, and the corresponding debug info
file is placed in the .build-id directory.
We could do both, but the former, which 'make deb-pkg' currently does,
results in complicated installation steps because we need to manually
strip the debug sections, create debug links, and re-sign the modules.
Besides, it is not working with module compression.
This commit abandons the approach [1], and instead opts for [2].

Since commit 491b146d4c ("kbuild: builddeb: Eliminate debian/arch

dpkg-architecture: error: unknown option 'DEB_HOST_MULTIARCH'
The current code:
dpkg-architecture -a$DEB_HOST_ARCH -qDEB_HOST_MULTIARCH
... does not look sensible because:
- For this code to work correctly, DEB_HOST_ARCH must be pre-defined,
which is true when the packages are built via dpkg-buildpackage.
In this case, DEB_HOST_MULTIARCH is also likely defined, hence there
is no need to query DEB_HOST_MULTIARCH in the first place.
- If DEB_HOST_MULTIARCH is undefined, DEB_HOST_ARCH is likely undefined
too. So, you cannot query DEB_HOST_MULTIARCH in this way. This is
mostly the case where debian/rules is directly executed.
When debian/rules is directly executed, querying DEB_HOST_MUCHARCH is
not enough because we need to know DEB_{BUILD,HOST}_GNU_TYPE as well.
All DEB_* variables are defined when the package build is initiated by
dpkg-buildpackage, but otherwise, let's call dpkg-architecture to set
all DEB_* environment variables.
