2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman1-0/+1
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.

Script `config' relies on extensions of `GNU sed', and is thus not working on all Unixes: - in-place edition of files (-i), which can be replaced with a temporary file; - extended-regexps (-r), which can be split into basic regexps; - single-line calls to `a' command, while some implementations require a leading newline before the parameter. Rewrite calls to `sed' to comply with POSIX interface, and move them to helper functions. Signed-off-by: Clement Chauplannaz <chauplac@gmail.com> Tested-by: "Yann E.

The script `config' prints its name in usage() function. It is currently hard-coded to value `config'.

2013-05-20scripts/config: fix assignment of parameters for short version of --*-after ↵Clement Chauplannaz1-1/+1
options When --*-after options are used, two parameters are parsed from the command-line before the adequate function is called: - the `before' option, after which the new option will be inserted, - the name of the option to enable/disable/modularise. With the short version of --*-after options (namely -E, -D, -M), the parsing step is not performed which leads to processing unset variables. Add options -E, -D, -M to the test that triggers assignment of parameters for --*-after options.

2012-06-28scripts/config: allow alternate prefix to config option symbolYann E. MORIN1-13/+19
While the Linux kernel uses 'CONFIG_' as a prefix to the config options symbols, many projects that use kconfig may use different prefixes, or even none at all. If the CONFIG_ environment variable is set, use it as the prefix (empty is a valid prefix). Otherwise, use the default prefix 'CONFIG_'. This matches the support for alternate prefixes in scripts/kconfig/lkc.h, which uses the same logic (albeit with a C define instead of an environment variable). Signed-off-by: "Yann E.

2012-06-28scripts/config: add option to not upper-case symbolsYann E. MORIN1-3/+15
Currently, scripts/config mangles the config option symbols to always be upper-case. While the Linux kernel almost exclusively uses upper-case symbols, there are still a few symbols with lower-case which this script can not handle: $ grep -r -E '^[[:space:]]*config[[:space:]]+[^[:space:]]*[[:lower:]][^[:space:]=.]*$' . |wc -l 173 (that's roughly 1.3% of the symbols in 3.5-rc1) Eg.: ./arch/arm/Kconfig:config VFPv3 ./arch/powerpc/platforms/Kconfig.cputype:config 40x ./arch/x86/Kconfig:config SCx200HR_TIMER ./drivers/video/console/Kconfig:config FONT_8x8 ./drivers/video/Kconfig:config NTSC_640x480 Also, other projects that use kconfig may allow for lower- or mixed-case symbols, and may find easier to reuse this script than implement each their own (potentially flawed) logic. For such a use-case, see: http://marc.info/?l=linux-kbuild&m=133409932115848&w=2 This patch adds a new option to keep the given case, and keep the current default to upper-case the symbols.

2012-05-16scripts/config: properly report and set string optionsYann E. MORIN1-4/+7
Currently, scripts/config removes the leading double-quote from string options, but leaves the trailing double-quote. Also, double-quotes in a string are escaped, but scripts/config does not unescape those when printing Finally, scripts/config does not escape double-quotes when setting string options.

2009-01-07kconfig: add script to manipulate .config files on the command lineAndi Kleen1-0/+150
I often change single options in .config files. Instead of using an editor or one of the frontends it's convenient to do this from the command line. It's also useful to do from automated build scripts when building different variants from a base config file. I extracted most of the CONFIG manipulation code from one of my build scripts into a new shell script scripts/config The script is not integrated with the normal Kconfig machinery and doesn't do any checking against Kconfig files, but just manipulates that text format. This is always done at make time anyways. I believe this script would be a useful standard addition for scripts/* Sample usage: ./scripts/config --disable smp Disable SMP in .config file ./scripts/config --file otherdir/.config --module e1000e Enable E1000E as module in otherdir/.config ./scripts/config --state smp y Check state of config option CONFIG_SMP After merging into git please make scripts/config executable Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
