Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

kbuild: pkg: rename scripts/package/Makefile to scripts/Makefile.package 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 <yamada.masahiro@socionext.com>

kbuild: use git-archive for source package creation Commit 5c3d1d0abb12 ("kbuild: add a tool to list files ignored by git") added a new tool, scripts/list-gitignored. My intention was to create source packages without cleaning the source tree, without relying on git. Linus strongly objected to it, and suggested using 'git archive' instead. [1] [2] [3] This commit goes in that direction - Remove scripts/list-gitignored.c and rewrites Makefiles and scripts to use 'git archive' for building Debian and RPM source packages. It also makes 'make perf-tar*-src-pkg' use 'git archive' again. Going forward, building source packages is only possible in a git-managed tree. Building binary packages does not require git.

kbuild: deb-pkg: create source package without cleaning If you run 'make deb-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, *.diff.gz contained some check-in files such as .clang-format, .cocciconfig. With this commit, *.diff.gz will only contain the .config and debian/. The other source files will go into the .orig tarball. linux.tar.gz is rebuilt only when the source files that would go into the tarball are changed.

kbuild: rpm-pkg: skip build dependency check on non-rpm systems Commit 8818039f959b ("kbuild: add ability to make source rpm buildable using koji") added the BuildRequires: field. Checking the build dependency is fine, but one annoyance is that 'make (bin)rpm-pkg' fails on non-rpm systems [1]. For example, Debian provides rpmbuild via 'apt install rpm', but of course cannot meet the requirement listed in the BuildRequires: field. It is possible to pass RPMOPTS=--nodeps to work around it, but it is reasonable to do it automatically. If 'rpm -q rpm' fails, it is not an RPM-managed system. (The command 'rpm' is not installed at all, or was installed by other means.) In that case, pass --nodeps to skip the build dependency check.

kbuild: unexport abs_srctree and abs_objtree Commit 25b146c5b8ce ("kbuild: allow Kbuild to start from any directory") exported abs_srctree and abs_objtree to avoid recomputation after the sub-make. However, this approach turned out to be fragile. Commit 5fa94ceb793e ("kbuild: set correct abs_srctree and abs_objtree for package builds") moved them above "ifneq ($(sub_make_done),1)", eliminating the need for exporting them. These are only needed in the top Makefile. If an absolute path is required in sub-directories, you can use $(abspath ) or $(realpath ) as needed.

scripts/package: snap-pkg target Following in footsteps of other targets like 'deb-pkg, 'rpm-pkg' and 'tar-pkg', this patch adds a 'snap-pkg' target for the creation of a Linux kernel snap package using the kbuild infrastructure. A snap, in its general form, is a self contained, sandboxed, universal package and it is intended to work across multiple distributions and/or devices. A snap package is distributed as a single compressed squashfs filesystem. A kernel snap is a snap package carrying the Linux kernel, kernel modules, accessory files (DTBs, System.map, etc) and a manifesto file. The purpose of a kernel snap is to carry the Linux kernel during the creation of a system image, eg. Ubuntu Core, and its subsequent upgrades.

Creating native packages from the kernel tree has multiple advantages: * The package triggers the correct hooks for initramfs generation and bootloader configuration * Uninstallation is complete and also invokes the relevant hooks * New UAPI headers can be installed without any manual bookkeeping The PKGBUILD file is a modified version of the one used for the downstream Arch Linux "linux" package.

kbuild: use git-archive for source package creation Commit 5c3d1d0abb12 ("kbuild: add a tool to list files ignored by git") added a new tool, scripts/list-gitignored. My intention was to create source packages without cleaning the source tree, without relying on git. Linus strongly objected to it, and suggested using 'git archive' instead. [1] [2] [3] This commit goes in that direction - Remove scripts/list-gitignored.c and rewrites Makefiles and scripts to use 'git archive' for building Debian and RPM source packages. It also makes 'make perf-tar*-src-pkg' use 'git archive' again. Going forward, building source packages is only possible in a git-managed tree. Building binary packages does not require git.

kbuild: do not create intermediate *.tar for source tarballs Since commit 05e96e96a315 ("kbuild: use git-archive for source package creation"), a source tarball is created in two steps; create *.tar file then compress it. I split the compression as a separate rule because I just thought 'git archive' supported only gzip. For other compression algorithms, I could pipe the two commands: $ git archive HEAD | xz > linux.tar.xz I read git-archive(1) carefully, and I realized GIT had provided a more elegant way: $ git -c tar.tar.xz.command=xz archive -o linux.tar.xz HEAD This commit uses 'tar.tar.*.command' configuration to specify the compression backend so we can compress a source tarball on-the-fly. GIT commit 767cf4579f0e ("archive: implement configurable tar filters") is more than a decade old, so it should be available on almost all build environments.

kbuild: use proper prefix for tarballs to fix rpm-pkg build error Since commit f8d94c4e403c ("kbuild: do not create intermediate *.tar for source tarballs"), 'make rpm-pkg' fails because the prefix of the source tarball is 'linux.tar/' instead of 'linux/'. $(basename $@) strips only '.gz' from the filename linux.tar.gz. You need to strip two suffixes from compressed tarballs and one suffix from uncompressed tarballs (for example 'perf-6.3.0.tar' generated by 'make perf-tar-src-pkg'). One tricky fix might be --prefix=$(firstword $(subst .tar, ,$@))/ but I think it is better to hard-code the prefix.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

kbuild: make perf-tar*-src-pkg work without relying on git Currently, perf-tar*-src-pkg only uses 'git archive', but it is better to make it work without relying on git. The file, HEAD, which saves the commit hash, will be included in the tarball only when the source tree is managed by git. The git tree is more precisely checked; it has been copied from scripts/setlocalversion. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

kbuild: deb-pkg: create source package without cleaning If you run 'make deb-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, *.diff.gz contained some check-in files such as .clang-format, .cocciconfig. With this commit, *.diff.gz will only contain the .config and debian/. The other source files will go into the .orig tarball. linux.tar.gz is rebuilt only when the source files that would go into the tarball are changed.

kbuild: use git-archive for source package creation Commit 5c3d1d0abb12 ("kbuild: add a tool to list files ignored by git") added a new tool, scripts/list-gitignored. My intention was to create source packages without cleaning the source tree, without relying on git. Linus strongly objected to it, and suggested using 'git archive' instead. [1] [2] [3] This commit goes in that direction - Remove scripts/list-gitignored.c and rewrites Makefiles and scripts to use 'git archive' for building Debian and RPM source packages. It also makes 'make perf-tar*-src-pkg' use 'git archive' again. Going forward, building source packages is only possible in a git-managed tree. Building binary packages does not require git.
