| * kbuild: resolve symlinks for O= properlyMasahiro Yamada2023-12-291-7/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, Kbuild follows the logical chain of directories for the O= option, just like 'cd' (or 'realpath --logical') does. Example: $ mkdir -p /tmp/a /tmp/x/y $ ln -s /tmp/x/y /tmp/a/b $ realpath /tmp/a/b/.. /tmp/x $ realpath --logical /tmp/a/b/.. /tmp/a $ make O=/tmp/a/b/.. defconfig make[1]: Entering directory '/tmp/a' [snip] make[1]: Leaving directory '/tmp/a' 'make O=/tmp/a/b/.. defconfig' creates the kernel configuration in /tmp/a instead of /tmp/x despite /tmp/a/b/.. resolves to /tmp/x. This is because Kbuild internally uses the 'cd ... && pwd' for the path resolution, but this behavior is not predictable for users. Additionally, it is not consistent with how the Kbuild handles the M= option or GNU Make works with 'make -C /tmp/a/b/..'. Using the physical directory structure for the O= option seems more reasonable. The comment says "expand a shell special character '~'", but it has already been expanded to the home directory in the command line.

| * kbuild: support W=c and W=e shorthands for KconfigMasahiro Yamada2023-12-031-0/+10

Associate them with KBUILD_EXTRA_WARN (and the W= shorthand). Support a new letter 'c' to enable extra checks in Kconfig. You can still manage compiler warnings (W=1) and Kconfig warnings (W=c) independently. Reuse the letter 'e' to turn Kconfig warnings into errors. As usual, you can combine multiple letters in KCONFIG_EXTRA_WARN. $ KCONFIG_WARN_UNKNOWN_SYMBOLS=1 KCONFIG_WERROR=1 make defconfig can be shortened to: $ KBUILD_EXTRA_WARN=ce make defconfig or, even shorter: $ make W=ce defconfig Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Nathan Chancellor <nathan@kernel.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | The rpm-pkg and deb-pkg targets have transitioned to using 'git archive' for tarball creation. Although the old cmd_src_tar is still used by snap-pkg, there is no need to pack and unpack a tarball solely for passing the source to snapcraft. Instead, you can use 'source-type: local' to tell the source location to snapcraft. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

With GNU Make >= 4.4, it is executed more than 60 times because exported variables are also passed to other $(shell ) invocations. Without careful coding, it is known to cause an exponential fork explosion. [1] The use of $(shell ) in an exported recursive variable is likely wrong because $(shell ) is always evaluated due to the 'export' keyword, and the evaluation can occur multiple times by the nature of recursive variables. Convert the shell script to a Makefile, which is included only when CONFIG_DEBUG_INFO_BTF=y.

Code duplication Many architectures duplicate similar code just for copying files to the install destination. Some architectures (arm, sparc, x86) create build-id symlinks, introducing more code duplication. 2. Unintended updates of in-tree build artifacts The vdso_install rule depends on the vdso files to install. It may update in-tree build artifacts. This can be problematic, as explained in commit 19514fc665ff ("arm, kbuild: make "make install" not depend on vmlinux"). 3. Broken code in some architectures Makefile code is often copied from one architecture to another without proper adaptation. 'make vdso_install' for parisc does not work. 'make vdso_install' for s390 installs vdso64, but not vdso32. To address these problems, this commit introduces a generic vdso_install rule. Architectures that support vdso_install need to define vdso-install-y in arch/*/Makefile. vdso-install-y lists the files to install. For example, arch/x86/Makefile looks like this: vdso-install-$(CONFIG_X86_64) += arch/x86/entry/vdso/vdso64.so.dbg vdso-install-$(CONFIG_X86_X32_ABI) += arch/x86/entry/vdso/vdsox32.so.dbg vdso-install-$(CONFIG_X86_32) += arch/x86/entry/vdso/vdso32.so.dbg vdso-install-$(CONFIG_IA32_EMULATION) += arch/x86/entry/vdso/vdso32.so.dbg These files will be installed to $(MODLIB)/vdso/ with the .dbg suffix, if exists, stripped away. vdso-install-y can optionally take the second field after the colon separator. This is needed because some architectures install a vdso file as a different base name. The following is a snippet from arch/arm64/Makefile. vdso-install-$(CONFIG_COMPAT_VDSO) += arch/arm64/kernel/vdso32/vdso.so.dbg:vdso32.so This will rename vdso.so.dbg to vdso32.so during installation. If such architectures change their implementation so that the base names match, this workaround will go away.

| * kbuild: Show marked Kconfig fragments in "help"Kees Cook2023-09-031-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the Kconfig fragments in kernel/configs and arch/*/configs that aren't used internally aren't discoverable through "make help", which consists of hard-coded lists of config fragments. Instead, list all the fragment targets that have a "# Help: " comment prefix so the targets can be generated dynamically. Add logic to the Makefile to search for and display the fragment and comment. Add comments to fragments that are intended to be direct targets.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts the old commit "kbuild: Introduce source symlink in /lib/modules/.../". [1] The current Kbuild does not require $(MODLIB)/source. If the kernel was built in a separate output directory, $(MODLIB)/build/Makefile wraps the Makefile in the source tree. It is enough for building external modules.

Start rearranging those by moving all options into Makefile.extrawarn.

| * kbuild: add a phony target to run a command with Kbuild env varsMasahiro Yamada2023-07-241-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are some cases where we want to run a command with the same environment variables as Kbuild uses. For example, 'make coccicheck' invokes scripts/coccicheck from the top Makefile so that the script can reference to ${LINUXINCLUDE}, ${KBUILD_EXTMOD}, etc. The top Makefile defines several phony targets that run a script. We do it also for an internally used script, which results in a somewhat complex call graph. One example: debian/rules binary-arch -> make intdeb-pkg -> scripts/package/builddeb It is also tedious to add a dedicated target like 'intdeb-pkg' for each use case. Add a generic target 'run-command' to run an arbitrary command in an environment with all Kbuild variables set. The usage is: $ make run-command KBUILD_RUN_COMMAND=<command> The concept is similar to: $ dpkg-architecture -c <command> This executes <command> in an environment which has all DEB_* variables defined. Convert the existing 'make intdeb-pkg'. Another possible usage is to interrogate a Make variable. $ make run-command KBUILD_RUN_COMMAND='echo $(KBUILD_CFLAGS)' might be useful to see KBUILD_CFLAGS set by the top Makefile.

| * kbuild: Enable -Wenum-conversion by defaultBorislav Petkov (AMD)2023-07-241-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This diagnostic checks whether there is a type mismatch when converting enums (assign an enum of type A to an enum of type B, for example) and it caught a legit issue recently. The reason it didn't show is because that warning is enabled only with -Wextra with GCC. Clang, however, enables it by default. GCC folks were considering enabling it by default but it was too noisy back then: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78736 Now that due to clang all those warnings have been fixed, enable it with GCC too. allmodconfig tests done with: x86, arm{,64}, powerpc{,64}, riscv crossbuilds.
