2023-02-26kbuild: rpm-pkg: remove unneeded KERNELRELEASE from modules/headers_installMasahiro Yamada1-2/+2
This is a temporary workaround added by commit f6e09b07cc12 ("kbuild: do not put .scmversion into the source tarball"). Since commit 1cb86b6c3136 ("kbuild: save overridden KERNELRELEASE in include/config/kernel.release"), the user-supplied KERNELRELEASE is saved in include/config/kernel.release. Remove it again.

2023-02-26kbuild: deb-pkg: improve the usability of source packageMasahiro Yamada2-5/+20
Improve the source package support in case the dpkg-buildpackage is directly used to build binary packages. For cross-compiling, you can set CROSS_COMPILE via the environment variable, but it is better to set it automatically - set it to ${DEB_HOST_GNU_TYPE}- if we are cross-compiling but not from the top Makefile. The generated source package may be carried to a different build environment, which may have a different compiler installed. Run olddefconfig first to set new CONFIG options to their default values without prompting. Take KERNELRELEASE and KBUILD_BUILD_VERSION from the version field of debian/changelog in case it is updated afterwards. Signed-off-by: Masahiro Yamada <[email protected]>
2023-02-26kbuild: deb-pkg: fix binary-arch and clean in debian/rulesMasahiro Yamada1-4/+2
The clean target needs ARCH=${ARCH} to clean up the tree for the correct architecture. 'make (bin)deb-pkg' skips cleaning, but the preclean hook may be executed if dpkg-buildpackage is directly used. The binary-arch target does not need KERNELRELEASE because it is not updated during the installation. KBUILD_BUILD_VERSION is not needed either because binary-arch does not build vmlinux.

2023-02-26kbuild: deb-pkg: switch over to source format 3.0 (quilt)Masahiro Yamada1-23/+18
Change the source format from "1.0" to "3.0 (quilt)" because it works more cleanly. All files except .config and debian/ go into the orig tarball. Add a single patch, debian/patches/config, and delete the ugly extend-diff-ignore patterns. The debian tarball will be compressed into *.debian.tar.xz by default. If you like to use a different compression mode, you can pass the command line option, DPKG_FLAGS=-Zgzip, for example. The orig tarball only supports gzip for now. The combination of gzip and xz is somewhat clumsy, but it is not a practical problem. Signed-off-by: Masahiro Yamada <[email protected]> Reviewed-by: Nicolas Schier <[email protected]>
2023-02-26kbuild: deb-pkg: hide KDEB_SOURCENAME from MakefileMasahiro Yamada1-1/+1

If you run 'make (src)rpm-pkg', all objects are lost due to 'make clean', which makes the incremental builds impossible. Instead of cleaning, pass the exclude list to tar's --exclude-from option. Previously, the .config was contained in the source tarball. With this commit, the source rpm consists of separate linux.tar.gz and .config. Remove stale comments.

Previously, *.diff.gz contained some check-in files such as .clang-format, .cocciconfig. With this commit, *.diff.gz will only contain the .config and debian/.

2023-01-30kbuild: do not put .scmversion into the source tarballMasahiro Yamada1-5/+3
.scmversion is used by (src)rpm-pkg and deb-pkg to carry KERNELRELEASE. In fact, deb-pkg does not rely on it any more because the generated debian/rules specifies KERNELRELEASE from the command line. Do likwise for (src)rpm-pkg, and remove this feature. For the same reason, you do not need to save LOCALVERSION in the spec file.

A fix was made in the mkspec script that uses a feature, ie. the OR expression, which requires RPM 4.13. However, the script indicates another minimum version. Lower versions may have success by using the --no-deps option as suggested, but feels like bumping the version to 4.13 is reasonable as it put me on the wrong track at first with RPM 4.11 on my Centos7 machine.

2022-12-30kbuild: rpm-pkg: add libelf-devel as alternative for BuildRequiresMasahiro Yamada1-1/+2
Guoqing Jiang reports that openSUSE cannot compile the kernel rpm due to "BuildRequires: elfutils-libelf-devel" added by commit 8818039f959b ("kbuild: add ability to make source rpm buildable using koji"). The relevant package name in openSUSE is libelf-devel. Add it as an alternative package. BTW, if it is impossible to solve the build requirement, the final resort would be: $ make RPMOPTS=--nodeps rpm-pkg This passes --nodeps to the rpmbuild command so it will not verify build dependencies. This is useful to test rpm builds on non-rpm system. On Debian/Ubuntu, for example, you can install rpmbuild by 'apt-get install rpm'. NOTE1: Likewise, it is possible to bypass the build dependency check for debian package builds: $ make DPKG_FLAGS=-d deb-pkg NOTE2: The 'or' operator is supported since RPM 4.13. So, old distros such as CentOS 7 will break. I suggest installing newer rpmbuild in such cases.

2022-11-17kbuild: Restore .version auto-increment behaviour for Debian packagesMarc Zyngier1-1/+1
Since 2df8220cc511 ("kbuild: build init/built-in.a just once"), generating Debian packages using 'make bindeb-pkg' results in packages that are stuck to the same .version, leading to unexpected behaviours (multiple packages with the same version). That's because the mkdebian script samples the build version before building the kernel, and forces the use of that version number for the actual build. Restore the previous behaviour by calling init/build-version instead of reading the .version file. This is likely to result in too many .version bumps, but this is what was happening before (although the bump was affecting builds made after the current one).

vmlinux.bz2 was added to the rpm packages in 2009 in the fc370ecfdb37 ("kbuild: add vmlinux to kernel rpm") but seemingly hasn't been used since. Originally this should have been split up in a seperate debugging package because it massively increases the size of the generated rpm's e.g. kernel rpm built using binrpm-pkg on Fedora 36 default 5.19.8 kernel config and localmodconfig is ~255MB with vmlinux.bz2 and only ~65MB without it.

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/.

2019-08-25kbuild: pkg: rename scripts/package/Makefile to scripts/Makefile.packageMasahiro Yamada1-156/+0
scripts/package/Makefile does not use $(obj) or $(src) at all. It actually generates files and directories in the top of $(objtree). I do not see much sense in descending into scripts/package/. Signed-off-by: Masahiro Yamada <[email protected]>
2019-08-25kbuild: pkg: add package targets to PHONY instead of FORCEMasahiro Yamada1-9/+20
These are not real targets. Adding them to PHONY is preferred. Signed-off-by: Masahiro Yamada <[email protected]>
2019-08-25kbuild: pkg: clean up package files/dirs from the top MakefileMasahiro Yamada1-9/+0
I am not a big fan of the $(objtree)/ hack for clean-files/clean-dirs. These are created in the top of $(objtree), so let's clean them up from the top Makefile. Signed-off-by: Masahiro Yamada <[email protected]>
