2024-07-16kbuild: package: add -e and -u options to some shell scriptsMasahiro Yamada
Set -e to make these scripts fail on the first error. Set -u because these scripts are invoked by Makefile, and do not work properly without necessary variables defined. I tweaked mkdebian to cope with optional environment variables. Remove the explicit "test -n ..." from install-extmod-build. Both options are described in POSIX.

2024-05-02kbuild: buildtar: remove warning for the default caseMasahiro Yamada
Given KBUILD_IMAGE properly set in arch/*/Makefile, the default case should work in most scenarios. The only oddity is the naming of the copy destination, vmlinux-kbuild-${KERNELRELEASE}. Let's rename it to vmlinuz-${KERNELRELEASE} because the kernel is often compressed. Remove the warning to avoid unnecessary patch submissions when the default case suffices. Remove the x86 case, which is now equivalent to the default. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Nathan Chancellor <nathan@kernel.org>
2024-05-02kbuild: buildtar: add comments about inconsistent package generationMasahiro Yamada
scripts/package/buildtar checks some kernel packages, and copies the first image found. This may potentially produce an inconsistent (and possibly wrong) package. For instance, the for-loop for arm64 checks Image.{bz2,gz,lz4,lzma,lzo}, and vmlinuz.efi, then copies the first image found, which might be a stale image created in a previous build. When CONFIG_EFI_ZBOOT is enabled in the pristine source tree, 'make ARCH=arm64 tar-pkg' will build and copy vmlinuz.efi. This is the expected behavior. If you build the kernel with CONFIG_EFI_ZBOOT disabled, Image.gz will be created, which will remain in the tree until you run 'make clean'. Even if CONFIG_EFI_ZBOOT is turned on later, 'make ARCH=arm64 tar-pkg' will copy stale Image.gz instead of the latest vmlinuz.efi, as Image.gz takes precedence over vmlinuz.efi. In summary, the code "[ -f ... ] && cp" does not consistently produce the desired outcome. Other packaging targets are deterministic; deb-pkg and rpm-pkg copies ${KBUILD_IMAGE}, which is determined by CONFIG options. I removed [ -f ... ] checks from x86, alpha, parisc, and the default because they have a single kernel image to copy. If it is missing, it should be an error. I did not modify the code for mips, arm64, riscv. Instead, I left some comments. Eventually, someone may fix the code, or at the very least, it may discourage the copy-pasting of incorrect code to another architecture.

Redefine GZIP, BZIP2, LZOP variables as KGZIP, KBZIP2, KLZOP resp. GZIP, BZIP2, LZOP env variables are reserved by the tools. The original attempt to redefine them internally doesn't work in makefiles/scripts intercall scenarios, e.g., "make GZIP=gzip bindeb-pkg" and results in broken builds. There can be other broken build commands because of this, so the universal solution is to use non-reserved env variables for the compression tools.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman
Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

2013-08-26kbuild: Add MIPS specific files to generated package.Stuart Longland
A lot of 64-bit systems supported by Linux/MIPS have boot firmware or bootloaders that only understand 32-bit ELF files, and as such, the vmlinux.32 target exists to support these systems. Therefore, it'd be nice if the tar-pkg target recognised this, and included the right version when packaging up a binary of the kernel. This updates buildtar to support MIPS targets. MIPS may use 'vmlinux' or 'vmlinux.32' depending on the target system. This uses 'vmlinux.32' in preference to 'vmlinux' where present (although I should check which is newer), including either file as /boot/vmlinux-${version}.

2012-09-27Kbuild: use normal compression settings for tar*-pkgAndi Kleen
For large kernel configurations (like a distribution kernel) targz-pkg takes a quite long time to just do the compression. I clocked it at 15+mins for a SUSE kernel like config on a fast system. And tarxz and bzip2 are even slower. The main reason is that the script that is doing the taring sets the highest compression level (-9). When I change it to just use the defaults the gzip time for the same kernel goes down to ~3 mins. I haven't tested xz and bzip, but I expect those to be much faster too. I'm not willing to wait that long for a small compression gain. So just change the script to use the defaults.
