kbuild: remove stale code for 'source' symlink in packaging scripts

2023-10-01T14:06:06Z

Since commit d8131c2965d5 ("kbuild: remove $(MODLIB)/source symlink"), modules_install does not create the 'source' symlink. Remove the stale code from builddeb and kernel.spec. Signed-off-by: Masahiro Yamada

kbuild: fix kernel-devel RPM package and linux-headers Deb package

2023-09-14T17:39:24Z

Since commit fe66b5d2ae72 ("kbuild: refactor kernel-devel RPM package and linux-headers Deb package"), the kernel-devel RPM package and linux-headers Deb package are broken. I double-quoted the $(find ... -type d), which resulted in newlines being included in the argument to the outer find comment. find: 'arch/arm64/include\narch/arm64/kvm/hyp/include': No such file or directory The outer find command is unneeded.

kbuild: deb-pkg: support DEB_BUILD_OPTIONS=parallel=N in debian/rules

2023-08-29T13:29:35Z

'make srcdeb-pkg' generates a source package, which you can build later by using dpkg-buildpackage. In older dpkg versions, 'dpkg-buildpackage --jobs=N' sets not only DEB_BUILD_OPTIONS but also MAKEFLAGS. Hence, passing -j or --jobs to dpkg-buildpackage was enough for kicking the parallel execution. The behavior was changed by commit 1d0ea9b2ba3f ("dpkg-buildpackage: Change -j, --jobs semantics to non-force mode") of dpkg project. [1] Since then, 'dpkg-buildpackage --jobs=N' sets only DEB_BUILD_OPTIONS, which is not parsed by the current debian/rules. To build the package in parallel, you need to pass the alternative --jobs-force option or set the MAKEFLAGS environment variable. Debian policy [2] suggests the following code snippet for debian/rules. ifneq (,$(filter parallel=%,$(DEB_BUILD_OPTIONS))) NUMJOBS = $(patsubst parallel=%,%,$(filter parallel=%,$(DEB_BUILD_OPTIONS))) MAKEFLAGS += -j$(NUMJOBS) endif I tweaked the code to filter out parallel=1 and passed --jobs=1 to dpkg-buildpackage from scripts/Makefile.package. It is needed to force 'make deb-pkg' without the -j option to run in serial. Please note that dpkg-buildpackage sets parallel= in DEB_BUILD_OPTIONS by default (that is, --jobs=auto is the default) and --jobs=1 is needed to restore the serial execution. When dpkg-buildpackage is invoked from Kbuild, the number of jobs is inherited from the top level Makefile. Passing --jobs=1 to dpkg-buildpackage allows debian/rules to skip parsing DEB_BUILD_OPTIONS.

kbuild: deb-pkg: split debian/rules

2023-08-07T16:08:54Z

debian/rules is generated by shell, but the escape sequence (\$) is unreadable. debian/rules embeds only two variables (ARCH and KERNELRELEASE). Split them out to debian/rules.vars, and check-in the rest of Makefile code to scripts/package/debian/rules. Signed-off-by: Masahiro Yamada Tested-by: Nathan Chancellor Reviewed-by: Nicolas Schier

kbuild: deb-pkg: use Debian compliant shebang for debian/rules

2023-08-07T16:08:54Z

Debian Policy "4.9. Main building script: debian/rules" requires "debian/rules must start with the line #!/usr/bin/make -f". [1] Currently, Kbuild does not follow this policy. When Kbuild generates debian/rules, "#!$(command -v $MAKE) -f" is expanded by shell. The resuling string may not be "#!/usr/bin/make -f". There was a reason to opt out the Debian policy. If you run '/path/to/my/custom/make deb-pkg', debian/rules must also be invoked by the same Make program. If #!/usr/bin/make were hard-coded in debian/rules, the sub-make would be executed by a possibly different Make version. This is problematic due to the MAKEFLAGS incompatibility, especially the job server flag. Old Make versions used --jobserver-fds to propagate job server file descriptors, but Make >= 4.2 uses --jobserver-auth. The flag disagreement between the parent/child Makes would result in a process fork explosion. However, having a non-standard path in the shebang causes another issue; the generated source package is not portable as such a path does not exist in other build environments. This commit solves those conflicting demands. Hard-code '#!/usr/bin/make -f' in debian/rules to create a portable and Debian-compliant source package. Pass '--rules-file=$(MAKE) -f debian/rules' when dpkg-buildpackage is invoked from Makefile so that debian/rules is executed by the same Make program as used to start Kbuild.

kbuild: rpm-pkg: refactor *rpm-pkg targets

2023-07-24T15:59:33Z

Merge the similar build targets. Also, make the output location consistent. Previously, source packages were created in the build directory, while binary packages under ~/rpmbuild/RPMS/. Now, Kbuild creates the rpmbuild/ directory in the build directory, and saves all packages under it. Signed-off-by: Masahiro Yamada

kbuild: rpm-pkg: split out the body of spec file

2023-07-24T15:59:33Z

Most of the lines in the spec file are independent of any build condition. Split the body of the spec file into scripts/package/kernel.spec. scripts/package/mkspec will prepend some env-dependent variables. Signed-off-by: Masahiro Yamada

kbuild: rpm-pkg: introduce %{with_devel} switch to select devel package

2023-07-24T15:59:33Z

scripts/package/mkspec preprocesses the spec file by sed, but it is unreadable. This commit removes the last portion of the sed scripting. Remove the $S$M prefixes from the conditionally generated lines. Instead, surround the code with %if %{with_devel} ... %endif. Signed-off-by: Masahiro Yamada

kbuild: rpm-pkg: run modules_install for non-modular kernel
