b2441318 - License cleanup: add SPDX GPL-2.0 license identifier to files with no license

Wed, 01 Nov 2017 14:07:57 +0000

License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseMany source files in the tree are missing licensing information, whichmakes it harder for compliance tools to determine the correct license.By default all files without license information are under the defaultlicense 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 bindingshorthand, which can be used instead of the full boiler plate text.This patch is based on work done by Thomas Gleixner and Kate Stewart andPhilippe Ombredanne.How this work was done:Patches were generated and checked against linux-4.14-rc6 for a subset ofthe 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 caseswhere non-standard license headers were used, and references to licensehad to be inferred by heuristics based on keywords.The analysis to determine which SPDX License Identifier to be applied toa file was done in a spreadsheet of side by side results from of theoutput of two independent scanners (ScanCode & Windriver) producing SPDXtag:value files created by Philippe Ombredanne. Philippe prepared thebase 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 filesassessed. Kate Stewart did a file by file comparison of the scannerresults in the spreadsheet to determine which SPDX license identifier(s)to be applied to the file. She confirmed any determination that was notimmediately 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 licenseidentifiers 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 thespreadsheet to determine the SPDX license identifiers to apply to thesource files by Kate, Philippe, Thomas and, in some cases, confirmationby lawyers working with the Linux Foundation.Kate also obtained a third independent scan of the 4.13 code base fromFOSSology, and compared selected files where the other two scannersdisagreed against that SPDX file, to see if there was new insights. TheWindriver scanner is based on an older version of FOSSology in part, sothey are related.Thomas did random spot checks in about 500 files from the spreadsheetsfor the uapi headers and agreed with SPDX license identifier in thefiles he inspected. For the non-uapi files Thomas did random spot checksin about 15000 files.In initial set of patches against 4.14-rc6, 3 files were found to havecopy/paste license identifier errors, and have been fixed to reflect thecorrect identifier.Additionally Philippe spent 10 hours this week doing a detailed manualinspection and review of the 12,461 patched files from the initial patchversion 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 correctThis produced a worksheet with 20 files needing minor correction. Thisworksheet was then exported into 3 different .csv files for thedifferent types of files to be modified.These .csv files were then reviewed by Greg. Thomas wrote a script toparse the csv files and add the proper SPDX tag to the file, in theformat that the file expected. This script was further refined by Gregbased on the output to detect more types of files automatically and todistinguish between header and source .c files (which need differentcomment types.) Finally Greg ran the script using the .csv files togenerate the patches.Reviewed-by: Kate Stewart Reviewed-by: Philippe Ombredanne Reviewed-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/arch/powerpc/platforms/512x/Makefile

7d71d5b2 - clk: mpc5xxx: switch to COMMON_CLK, retire PPC_CLOCK

Sat, 30 Nov 2013 22:51:27 +0000

clk: mpc5xxx: switch to COMMON_CLK, retire PPC_CLOCKthe setup before the change was- arch/powerpc/Kconfig had the PPC_CLOCK option, off by default- depending on the PPC_CLOCK option the arch/powerpc/kernel/clock.c file was built, which implements the clk.h API but always returns -ENOSYS unless a platform registers specific callbacks- the MPC52xx platform selected PPC_CLOCK but did not register any callbacks, thus all clk.h API calls keep resulting in -ENOSYS errors (which is OK, all peripheral drivers deal with the situation)- the MPC512x platform selected PPC_CLOCK and registered specific callbacks implemented in arch/powerpc/platforms/512x/clock.c, thus provided real support for the clock API- no other powerpc platform did select PPC_CLOCKthe situation after the change is- the MPC512x platform implements the COMMON_CLK interface, and thus the PPC_CLOCK approach in arch/powerpc/platforms/512x/clock.c has become obsolete- the MPC52xx platform still lacks genuine support for the clk.h API while this is not a change against the previous situation (the error code returned from COMMON_CLK stubs differs but every call still results in an error)- with all references gone, the arch/powerpc/kernel/clock.c wrapper and the PPC_CLOCK option have become obsolete, as did the clk_interface.h header filethe switch from PPC_CLOCK to COMMON_CLK is done for all platforms withinthe same commit such that multiplatform kernels (the combination of 512xand 52xx within one executable) keep workingCc: Mike Turquette Cc: Anatolij Gustschin Cc: linux-arm-kernel@lists.infradead.orgCc: linuxppc-dev@lists.ozlabs.orgSigned-off-by: Gerhard Sittig Signed-off-by: Anatolij Gustschin List of files: /linux-6.15/arch/powerpc/platforms/512x/Makefile

6d8cdb68 - clk: mpc512x: introduce COMMON_CLK for MPC512x (disabled)

Sat, 30 Nov 2013 22:51:24 +0000

clk: mpc512x: introduce COMMON_CLK for MPC512x (disabled)this change implements a clock driver for the MPC512x PowerPC platformwhich follows the COMMON_CLK approach and uses common clock driversshared with other platformsthis driver implements the publicly announced set of clocks (thoselisted in the dt-bindings header file), as well as generates additional'struct clk' items where the SoC hardware cannot easily get mapped tothe common primitives (shared code) of the clock API, or requires"intermediate clock nodes" to represent clocks that have both gates anddividersthe previous PPC_CLOCK implementation is kept in place and remainsactive for the moment, the newly introduced CCF clock driver willreceive additional support for backwards compatibility in a subsequentpatch before it gets enabled and will replace the PPC_CLOCK approachsome of the clock items get pre-enabled in the clock driver to not havethem automatically disabled by the underlying clock subsystem because oftheir being unused -- this approach is desirable because- some of the clocks are useful to have for diagnostics and information despite their not getting claimed by any drivers (CPU, internal and external RAM, internal busses, boot media)- some of the clocks aren't claimed by their peripheral drivers yet, either because of missing driver support or because device tree specs aren't available yet (but the workarounds will get removed as the drivers get adjusted and the device tree provides the clock specs)clkdev registration provides "alias names" for few clock items- to not break those peripheral drivers which encode their component index into the name that is used for clock lookup (UART, SPI, USB)- to not break those drivers which use names for the clock lookup which were encoded in the previous PPC_CLOCK implementation (NFC, VIU, CAN)this workaround will get removed as these drivers get adjusted afterdevice tree based clock lookup has become availablethe COMMON_CLK implementation copes with device trees which lack anoscillator node (backwards compat), the REF clock is then derived fromthe IPS bus frequency and multiplier values fetched from hardwareCc: Mike Turquette Cc: Anatolij Gustschin Cc: linux-arm-kernel@lists.infradead.orgCc: linuxppc-dev@lists.ozlabs.orgSigned-off-by: Gerhard Sittig Signed-off-by: Anatolij Gustschin List of files: /linux-6.15/arch/powerpc/platforms/512x/Makefile
