2024-11-27kbuild: deb-pkg: Don't fail if modules.order is missingMatt Fleming
Kernels built without CONFIG_MODULES might still want to create -dbg deb packages but install_linux_image_dbg() assumes modules.order always exists. This obviously isn't true if no modules were built, so we should skip reading modules.order in that case.

2024-10-31kbuild: deb-pkg: add pkg.linux-upstream.nokernelheaders build profileMasahiro Yamada
Since commit f1d87664b82a ("kbuild: cross-compile linux-headers package when possible"), 'make bindeb-pkg' may attempt to cross-compile the linux-headers package, but it fails under certain circumstances. For example, when CONFIG_MODULE_SIG_FORMAT is enabled on Debian, the following command fails: $ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- bindeb-pkg [ snip ] Rebuilding host programs with aarch64-linux-gnu-gcc...

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 Fixes: f1d87664b82a ("kbuild: cross-compile linux-headers package when possible") Reported-by: Ron Economos <re@w6rz.net> Closes: https://lore.kernel.org/all/b3d4f49e-7ddb-29ba-0967-689232329b53@w6rz.net/ Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Tested-by: Ron Economos <re@w6rz.net> Reviewed-by: Nicolas Schier <nicolas@fjasle.eu>

2024-01-05kbuild: deb-pkg: use build ID instead of debug link for dbg packageMasahiro Yamada
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]. Debian kernel commit de26137e2a9f ("Drop not needed extra step to add debug links") also stopped adding debug links. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2024-01-05kbuild: deb-pkg: set DEB_* variables if debian/rules is directly executedMasahiro Yamada
Since commit 491b146d4c13 ("kbuild: builddeb: Eliminate debian/arch use"), direct execution of debian/rules results in the following error: 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. This requires dpkg 1.20.6 or newer because --print-format option was added in dpkg commit 7c54fa2b232e ("dpkg-architecture: Add a --print-format option").

To avoid this, while continuing to use the version information from dh_listpackages, pass $version from $package as the second argument of install_kernel_headers().

There was a request to preprocess the module linker script like we do for the vmlinux one. (https://lkml.org/lkml/2020/8/21/512) The difference between vmlinux.lds and module.lds is that the latter is needed for external module builds, thus must be cleaned up by 'make mrproper' instead of 'make clean'. Also, it must be created by 'make modules_prepare'. You cannot put it in arch/$(SRCARCH)/kernel/, which is cleaned up by 'make clean'. I moved arch/$(SRCARCH)/kernel/module.lds to arch/$(SRCARCH)/include/asm/module.lds.h, which is included from scripts/module.lds.S. scripts/module.lds is fine because 'make clean' keeps all the build artifacts under scripts/.

At the end of "make bindeb-pkg" I noticed the following warning: dpkg-genchanges: warning: unknown substitution variable ${kernel:debarch} It turns out that since dpkg version 1.19.0 dpkg-genchanges honors substitution variables in the Description field, while earlier versions silently left them alone, see https://bugs.debian.org/856547. The result is an incomplete description of the linux-headers package in the generated .changes file. Fix it by passing the kernel:debarch substitution variable to dpkg-genchanges.

2017-09-21kbuild: deb-pkg: remove firmware package supportMasahiro Yamada
Commit 5620a0d1aacd ("firmware: delete in-kernel firmware") deleted in-kernel firmware support, including the firmware install command. So, the firmware package does not make sense any more. Remove it. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Riku Voipio <riku.voipio@linaro.org> Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2017-04-25builddeb: Update a few outdated and hardcoded stringsRiku Voipio
The builddeb script has some hardcoded references to Linux version 2.6 which is ancient. Drop Provides as the virtual packages provided are not useful anymore. Leave the Provides for linux-kernel-headers, as someone might still be referring to it. While at it, updated copyright date and drop Standards-Version: since the package isn't Debian Standards compliant anyways.
