| * Makefile: use -z pack-relative-relocsFangrui Song2023-04-171-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 27f2a4db76e8 ("Makefile: fix GDB warning with CONFIG_RELR") added --use-android-relr-tags to fix a GDB warning BFD: /android0/linux-next/vmlinux: unknown type [0x13] section `.relr.dyn' The GDB warning has been fixed in version 11.2. The DT_ANDROID_RELR tag was deprecated since DT_RELR was standardized. Thus, --use-android-relr-tags should be removed. While making the change, try -z pack-relative-relocs, which is supported since LLD 15. Keep supporting --pack-dyn-relocs=relr as well for older LLD versions. There is no indication of obsolescence for --pack-dyn-relocs=relr. As of today, GNU ld supports the latter option for x86 and powerpc64 ports and has no intention to support --pack-dyn-relocs=relr. In the absence of the glibc symbol version GLIBC_ABI_DT_RELR, --pack-dyn-relocs=relr and -z pack-relative-relocs are identical in ld.lld. GNU ld and newer versions of LLD report warnings (instead of errors) for unknown -z options. Only errors lead to non-zero exit codes. Therefore, we should test --pack-dyn-relocs=relr before testing -z pack-relative-relocs.

| * kbuild: use git-archive for source package creationMasahiro Yamada2023-03-161-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: add a tool to list files ignored by gitMasahiro Yamada2023-02-161-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In short, the motivation of this commit is to build a source package without cleaning the source tree. The deb-pkg and (src)rpm-pkg targets first run 'make clean' before creating a source tarball. Otherwise build artifacts such as *.o, *.a, etc. would be included in the tarball. Yet, the tarball ends up containing several garbage files since 'make clean' does not clean everything. Cleaning the tree every time is annoying since it makes the incremental build impossible. It is desirable to create a source tarball without cleaning the tree. In fact, there are some ways to achieve this. The easiest solution is 'git archive'. 'make perf-tar*-src-pkg' uses it, but I do not like it because it works only when the source tree is managed by git, and all files you want in the tarball must be committed in advance. I want to make it work without relying on git. We can do this. Files that are ignored by git are generated files, so should be excluded from the source tarball. We can list them out by parsing the .gitignore files. Of course, .gitignore does not cover all the cases, but it works well enough. tar(1) claims to support it: --exclude-vcs-ignores Exclude files that match patterns read from VCS-specific ignore files. Supported files are: .cvsignore, .gitignore, .bzrignore, and .hgignore. The best scenario would be to use 'tar --exclude-vcs-ignores', but this option does not work. --exclude-vcs-ignore does not understand any of the negation (!), preceding slash, following slash, etc.. So, this option is just useless. Hence, I wrote this gitignore parser. The previous version [1], written in Python, was so slow. This version is implemented in C, so it works much faster. I imported the code from git (commit: 23c56f7bd5f1), so we get the same result. This tool traverses the source tree, parsing all .gitignore files, and prints file paths that are ignored by git. The output is similar to 'git ls-files --ignored --directory --others --exclude-per-directory=.gitignore', except [1] Not sorted [2] No trailing slash for directories [2] is intentional because tar's --exclude-from option cannot handle trailing slashes. [How to test this tool] $ git clean -dfx $ make -s -j$(nproc) defconfig all # or allmodconifg or whatever $ git archive -o ../linux1.tar --prefix=./ HEAD $ tar tf ../linux1.tar | LANG=C sort > ../file-list1 # files emitted by 'git archive' $ make scripts_package HOSTCC scripts/list-gitignored $ scripts/list-gitignored --prefix=./ -o ../exclude-list $ tar cf ../linux2.tar --exclude-from=../exclude-list . $ tar tf ../linux2.tar | LANG=C sort > ../file-list2 # files emitted by 'tar' $ diff ../file-list1 ../file-list2 | grep -E '^(<|>)' < ./Documentation/devicetree/bindings/.yamllint < ./drivers/clk/.kunitconfig < ./drivers/gpu/drm/tests/.kunitconfig < ./drivers/hid/.kunitconfig < ./fs/ext4/.kunitconfig < ./fs/fat/.kunitconfig < ./kernel/kcsan/.kunitconfig < ./lib/kunit/.kunitconfig < ./mm/kfence/.kunitconfig < ./tools/testing/selftests/arm64/tags/ < ./tools/testing/selftests/arm64/tags/.gitignore < ./tools/testing/selftests/arm64/tags/Makefile < ./tools/testing/selftests/arm64/tags/run_tags_test.sh < ./tools/testing/selftests/arm64/tags/tags_test.c < ./tools/testing/selftests/kvm/.gitignore < ./tools/testing/selftests/kvm/Makefile < ./tools/testing/selftests/kvm/config < ./tools/testing/selftests/kvm/settings The source tarball contains most of files that are tracked by git.

| * kbuild: remove --include-dir MAKEFLAG from top MakefileMasahiro Yamada2023-02-051-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I added $(srctree)/ to some included Makefiles in the following commits: - 3204a7fb98a3 ("kbuild: prefix $(srctree)/ to some included Makefiles") - d82856395505 ("kbuild: do not require sub-make for separate output tree builds") They were a preparation for removing --include-dir flag. I have never thought --include-dir useful. Rather, it _is_ harmful. For example, run the following commands: $ make -s ARCH=x86 mrproper defconfig $ make ARCH=arm O=foo dtbs make[1]: Entering directory '/tmp/linux/foo' HOSTCC scripts/basic/fixdep Error: kernelrelease not valid - run 'make prepare' to update it UPD include/config/kernel.release make[1]: Leaving directory '/tmp/linux/foo' The first command configures the source tree for x86. The next command tries to build ARM device trees in the separate foo/ directory - this must stop because the directory foo/ has not been configured yet. However, due to --include-dir=$(abs_srctree), the top Makefile includes the wrong include/config/auto.conf from the source tree and continues building. Kbuild traverses the directory tree, but of course it does not work correctly. The Error message is also pointless - 'make prepare' does not help at all for fixing the issue. This commit fixes more arch Makefile, and finally removes --include-dir from the top Makefile. There are more breakages under drivers/, but I do not volunteer to fix them all. I just moved --include-dir to drivers/Makefile. With this commit, the second command will stop with a sensible message. $ make -s ARCH=x86 mrproper defconfig $ make ARCH=arm O=foo dtbs make[1]: Entering directory '/tmp/linux/foo' SYNC include/config/auto.conf.cmd *** *** The source tree is not clean, please run 'make ARCH=arm mrproper' *** in /tmp/linux *** make[2]: *** [../Makefile:646: outputmakefile] Error 1 /tmp/linux/Makefile:770: include/config/auto.conf.cmd: No such file or directory make[1]: *** [/tmp/linux/Makefile:793: include/config/auto.conf.cmd] Error 2 make[1]: Leaving directory '/tmp/linux/foo' make: *** [Makefile:226: __sub-make] Error 2 Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

If you want to avoid it, please add -Otarget option. Kbuild will never set it by default because Make would buffer the logs and lose the escape sequences. (Modern compilers print warnings and errors in color, but only when they write to a terminal.) This is also a preparation for supporting V=12 because V=2 appends the reason for rebuilding to the short log.

However, the dependencies are not handled and it only works if 'make dt_bindings_check' was run first and generated processed-schema.json. In addition, changing a binding file doesn't cause the schema to be rebuilt and dtb to be revalidated. Making this work turns out to be simple. Whenever CHECK_DTBS is set, make 'dt_binding_check' a 'dtbs_prepare' dependency. I reimplemented here what Masahiro had originally come up with a while back.

The generated zImage is correct despite the error message. As the commit description of 98da874c4303 [1] says, exported variables are passed down to $(shell ) functions, which means exported recursive variables might be expanded earlier than before, in the parse stage. The following test code demonstrates the change for GNU Make 4.4. [Test Makefile] $(shell echo hello > foo) export foo = $(shell cat bar/../foo) $(shell mkdir bar) all: @echo $(foo) [GNU Make 4.3] $ rm -rf bar; make-4.3 hello [GNU Make 4.4] $ rm -rf bar; make-4.4 cat: bar/../foo: No such file or directory hello The 'foo' is a resursively expanded (i.e. lazily expanded) variable. GNU Make 4.3 expands 'foo' just before running the recipe '@echo $(foo)', at this point, the directory 'bar' exists. GNU Make 4.4 expands 'foo' to evaluate $(shell mkdir bar) because it is exported. At this point, the directory 'bar' does not exit yet. The cat command cannot resolve the bar/../foo path, hence the error message. Let's get back to the kernel Makefile. In arch/arm/boot/compressed/Makefile, KBSS_SZ is referenced by LDFLAGS_vmlinux, which is recursive and also exported by the top Makefile. GNU Make 4.3 expands KBSS_SZ just before running the recipes, so no error message. GNU Make 4.4 expands KBSS_SZ in the parse stage, where the directory arm/arm/boot/compressed does not exit yet. When compiled with O=, the output directory is created by $(shell mkdir -p $(obj-dirs)) in scripts/Makefile.build. There are two ways to fix this particular issue: - change "$(obj)/../../../../vmlinux" in KBSS_SZ to "vmlinux" - unexport LDFLAGS_vmlinux This commit takes the latter course because it is what I originally intended. Commit 3ec8a5b33dea ("kbuild: do not export LDFLAGS_vmlinux") unexported LDFLAGS_vmlinux. Commit 5d4aeffbf709 ("kbuild: rebuild .vmlinux.export.o when its prerequisite is updated") accidentally exported it again. We can clean up arch/arm/boot/compressed/Makefile later.
