kbuild: pacman-pkg: make "rc" releases adhere to pacman versioning scheme

2026-06-01T15:46:31+00:00

[ Upstream commit 202550713128da20d9381d6d2dc0f6b73839f434 ] The package versioning scheme does not enable smooth upgrades from "rc" releases to the corresponding stable releases (e.g. 7.0.0-rc7 -> 7.0.0) because pacman considers that a downgrade due to the underscore in pkgver (e.g. 7.0.0_rc7), see e.g. vercmp(8) for an explanation of the package version comparison used by pacman. Package versions which are derived from said releases (e.g. built from git revisions) are similarly affected. Fix this by modifying pkgver in order to remove the hyphen from kernel versions containing "-rcN", where N is a non-negative integer.

kbuild: builddeb - avoid recompiles for non-cross-compiles

2026-05-23T11:04:51+00:00

[ Upstream commit 2452dcf4d740effff5aa71b7f6529ee8c04fd8f6 ] Commit e2c318225ac1 ("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 f1d87664b82a ("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.

kbuild: install-extmod-build: Package resolve_btfids if necessary

2026-04-02T11:09:27+00:00

[ Upstream commit 459cb3c054c2352bb321648744b620259a716b60 ] When CONFIG_DEBUG_INFO_BTF_MODULES is enabled and vmlinux is available, Makefile.modfinal and gen-btf.sh will try to use resolve_btfids on the module .ko. install-extmod-build currently does not package resolve_btfids, so that step fails.

kbuild: deb-pkg: don't set KBUILD_BUILD_VERSION unconditionally

2025-04-10T12:39:35+00:00

[ Upstream commit 62604063621fb075c7966286bdddcb057d883fa8 ] In ThinPro, we use the convention +hp for the kernel package. This does not have a dash in the name or version. This is built by editing ".version" before a build, and setting EXTRAVERSION="+hp" and KDEB_PKGVERSION make variables: echo 68 > .version make -j EXTRAVERSION="+hp" bindeb-pkg KDEB_PKGVERSION=6.12.2+hp69 .deb name: linux-image-6.12.2+hp_6.12.2+hp69_amd64.deb Since commit 7d4f07d5cb71 ("kbuild: deb-pkg: squash scripts/package/deb-build-option to debian/rules"), this no longer works. The deb build logic changed, even though, the commit message implies that the logic should be unmodified. Before, KBUILD_BUILD_VERSION was not set if the KDEB_PKGVERSION did not contain a dash. After the change KBUILD_BUILD_VERSION is always set to KDEB_PKGVERSION. Since this determines UTS_VERSION, the uname output to look off: (now) uname -a: version 6.12.2+hp ... #6.12.2+hp69 (expected) uname -a: version 6.12.2+hp ... #69 Update the debian/rules logic to restore the original behavior.

kbuild: deb-pkg: add pkg.linux-upstream.nokernelheaders build profile

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 Closes: https://lore.kernel.org/all/b3d4f49e-7ddb-29ba-0967-689232329b53@w6rz.net/ Signed-off-by: Masahiro Yamada Tested-by: Ron Economos Reviewed-by: Nicolas Schier
