2023-04-24scripts: Remove ICC-related dead codeRuihan Li1-4/+0
Intel compiler support has already been completely removed in commit 95207db8166a ("Remove Intel compiler support"). However, it appears that there is still some ICC-related code in scripts/cc-version.sh. There is no harm in leaving the code as it is, but removing the dead code makes the codebase a bit cleaner. Hopefully all ICC-related stuff in the build scripts will be removed after this commit, given the grep output as below: (linux/scripts) $ grep -i -w -R 'icc' cc-version.sh:ICC) cc-version.sh: min_version=$($min_tool_version icc) dtc/include-prefixes/arm64/qcom/sm6350.dtsi:#include <dt-bindings/interconnect/qcom,icc.h> Fixes: 95207db8166a ("Remove Intel compiler support") Signed-off-by: Ruihan Li <lrh2000@pku.edu.cn> Reviewed-by: Nick Desaulniers <ndesaulniers@google.com> Reviewed-by: Nathan Chancellor <nathan@kernel.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2023-04-23kbuild: use proper prefix for tarballs to fix rpm-pkg build errorMasahiro Yamada1-3/+3
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.

2023-04-19rust: fix regexp in scripts/is_rust_module.shAndrea Righi1-1/+1
nm can use "R" or "r" to show read-only data sections, but scripts/is_rust_module.sh can only recognize "r", so with some versions of binutils it can fail to detect if a module is a Rust module or not. Right now we're using this script only to determine if we need to skip BTF generation (that is disabled globally if CONFIG_RUST is enabled), but it's still nice to fix this script to do the proper job. Moreover, with this patch applied I can also relax the constraint of "RUST depends on !DEBUG_INFO_BTF" and build a kernel with Rust and BTF enabled at the same time (of course BTF generation is still skipped for Rust modules). [ Miguel: The actual reason is likely to be a change on the Rust compiler between 1.61.0 and 1.62.0: echo '#[used] static S: () = ();' | rustup run 1.61.0 rustc --emit=obj --crate-type=lib - && nm rust_out.o echo '#[used] static S: () = ();' | rustup run 1.62.0 rustc --emit=obj --crate-type=lib - && nm rust_out.o Gives: 0000000000000000 r _ZN8rust_out1S17h48027ce0da975467E 0000000000000000 R _ZN8rust_out1S17h58e1f3d9c0e97cefE See https://godbolt.org/z/KE6jneoo4. ] Signed-off-by: Andrea Righi <andrea.righi@canonical.com> Reviewed-by: Vincenzo Palazzo <vincenzopalazzodev@gmail.com> Reviewed-by: Eric Curtin <ecurtin@redhat.com> Reviewed-by: Martin Rodriguez Reboredo <yakoyoku@gmail.com> Signed-off-by: Miguel Ojeda <ojeda@kernel.org>

Commit 05e96e96a315 ("kbuild: use git-archive for source package creation") split the compression as a separate step to factor out the common build rules.

2023-04-16kbuild: do not create intermediate *.tar for source tarballsMasahiro Yamada1-7/+17
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.

2023-04-11kbuild: give up untracked files for source package buildsMasahiro Yamada4-89/+90
When the source tree is dirty and contains untracked files, package builds may fail, for example, when a broken symlink exists, a file path contains whitespaces, etc. Since commit 05e96e96a315 ("kbuild: use git-archive for source package creation"), the source tarball only contains committed files because it is created by 'git archive'. scripts/package/gen-diff-patch tries to address the diff from HEAD, but including untracked files by the hand-crafted script introduces more complexity. I wrote a patch [1] to make it work in most cases, but still wonder if this is what we should aim for. To simplify the code, this patch just gives up untracked files. Going forward, it is your responsibility to do 'git add' for what you want in the source package. The script shows a warning just in case you forgot to do so. It should be checked only when building source packages.

To avoid this, while continuing to use the version information from dh_listpackages, pass $version from $package as the second argument of install_kernel_headers().

2023-03-16kbuild: use git-archive for source package creationMasahiro Yamada9-1149/+180
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.

Clang 15 provides an option to prefix memcpy/memset/memmove calls with __asan_/__hwasan_ in instrumented functions: https://reviews.llvm.org/D122724 GCC will add support in future: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108777 Use it to regain KASAN instrumentation of memcpy/memset/memmove on architectures that require noinstr to be really free from instrumented mem*() functions (all GENERIC_ENTRY architectures).

This is a temporary workaround added by commit f6e09b07cc12 ("kbuild: do not put .scmversion into the source tarball"). Since commit 1cb86b6c3136 ("kbuild: save overridden KERNELRELEASE in include/config/kernel.release"), the user-supplied KERNELRELEASE is saved in include/config/kernel.release. Remove it again.

2023-02-26kbuild: deb-pkg: improve the usability of source packageMasahiro Yamada2-5/+20
Improve the source package support in case the dpkg-buildpackage is directly used to build binary packages. For cross-compiling, you can set CROSS_COMPILE via the environment variable, but it is better to set it automatically - set it to ${DEB_HOST_GNU_TYPE}- if we are cross-compiling but not from the top Makefile. The generated source package may be carried to a different build environment, which may have a different compiler installed. Run olddefconfig first to set new CONFIG options to their default values without prompting. Take KERNELRELEASE and KBUILD_BUILD_VERSION from the version field of debian/changelog in case it is updated afterwards. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2023-02-26kbuild: deb-pkg: fix binary-arch and clean in debian/rulesMasahiro Yamada1-4/+2
The clean target needs ARCH=${ARCH} to clean up the tree for the correct architecture. 'make (bin)deb-pkg' skips cleaning, but the preclean hook may be executed if dpkg-buildpackage is directly used. The binary-arch target does not need KERNELRELEASE because it is not updated during the installation. KBUILD_BUILD_VERSION is not needed either because binary-arch does not build vmlinux.

2023-02-26kbuild: make perf-tar*-src-pkg work without relying on gitMasahiro Yamada1-33/+64
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>
2023-02-26kbuild: deb-pkg: switch over to source format 3.0 (quilt)Masahiro Yamada2-24/+19
Change the source format from "1.0" to "3.0 (quilt)" because it works more cleanly. All files except .config and debian/ go into the orig tarball. Add a single patch, debian/patches/config, and delete the ugly extend-diff-ignore patterns. The debian tarball will be compressed into *.debian.tar.xz by default. If you like to use a different compression mode, you can pass the command line option, DPKG_FLAGS=-Zgzip, for example. The orig tarball only supports gzip for now. The combination of gzip and xz is somewhat clumsy, but it is not a practical problem. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Nicolas Schier <nicolas@fjasle.eu>

If '..' belongs to the same filesystem, create a hard link instead of a copy. In most cases, you can save disk space. I do not want to use 'mv' because keeping linux.tar.gz is useful to avoid unneeded rebuilding of the tarball.

scripts/Makefile.package does not need to know the value of KDEB_SOURCENAME because the source name can be taken from debian/changelog by using dpkg-parsechangelog.

If you run 'make (src)rpm-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, the .config was contained in the source tarball. With this commit, the source rpm consists of separate linux.tar.gz and .config. Remove stale comments. Now, 'make (src)rpm-pkg' works with O= option. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

The build rules of rpm-pkg and srcrpm-pkg are almost the same. Remove the code duplication. Change rpm-pkg to build binary packages from the source package generated by srcrpm-pkg. This changes the output directory of the srpm generated by 'make rpm-pkg' because srcrpm-pkg overrides _srcrpmdir. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

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.

Hopefully all should be good now, and Saravana will be keeping a watch for any potential regression on odd embedded systems. - driver core changes to work to make struct bus_type able to be moved into read-only memory (i.e. const) The recent work with Rust has pointed out a number of areas in the driver core where we are passing around and working with structures that really do not have to be dynamic at all, and they should be able to be read-only making things safer overall. This is the contuation of that work (started last release with kobject changes) in moving struct bus_type to be constant.
