      License cleanup: add SPDX GPL-2.0 license identifier to files with no license · b2441318
      Greg Kroah-Hartman authored
      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
      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.

      scripts/dtc: dtx_diff - 2nd update of include dts paths to match build · 35f3c984
      Frank Rowand authored
      Update dtx_diff include paths in the same manner as:
      commit b12869a8 ("of: remove drivers/of/testcase-data from
      include search path for CPP"), commit 5ffa2aed ("of: remove
      arch/$(SRCARCH)/boot/dts from include search path for CPP"), and
      commit 50f9ddaf ("of: search scripts/dtc/include-prefixes path
      for both CPP and DTC").
      Remove proposed include path kernel/dts/, which was never implemented
      for the dtb build.
      For the diff case, each source file is compiled separately.  For
      each of those compiles, provide the location of the source file
      as an include path, not the location of both source files.

      scripts/dtc: fix '%zx' warning · e6618692
      Russell King authored
      dtc uses an incorrect format specifier for printing a uint64_t value.
      uint64_t may be either 'unsigned long' or 'unsigned long long' depending
      on the host architecture.
      Fix this by using %llx and casting to unsigned long long, which ensures
      that we always have a wide enough variable to print 64 bits of hex.

      scripts/dtc: dtx_diff - Show real file names in diff header · 7782b144
      Geert Uytterhoeven authored
      As the comparison uses process substitution to pass files after
      conversion to DTS format, the diff header doesn't show the real
      filenames, but the names of the file descriptors used:
          --- /dev/fd/63  2017-06-22 11:21:47.531637188 +0200
          +++ /dev/fd/62  2017-06-22 11:21:47.531637188 +0200
      This is especially annoying when comparing a bunch of DT files in a
      loop, as the output doesn't show a clue about which files it refers to.
      Fix this by explicitly passing the original file names to the diff
      command using the --label option, giving e.g.:
          --- arch/arm/boot/dts/r8a7791-koelsch.dtb
          +++ arch/arm/boot/dts/r8a7791-porter.dtb

      devicetree: Move include prefixes from arch to separate directory · d5d332d3
      Olof Johansson authored
      We use a directory under arch/$ARCH/boot/dts as an include path
      that has links outside of the subtree to find dt-bindings from under
      include/dt-bindings. That's been working well, but new DT architectures
      haven't been adding them by default.
      Recently there's been a desire to share some of the DT material between
      arm and arm64, which originally caused developers to create symlinks or
      relative includes between the subtrees. This isn't ideal -- it breaks
      if the DT files aren't stored in the exact same hierarchy as the kernel
      tree, and generally it's just icky.
      As a somewhat cleaner solution we decided to add a $ARCH/ prefix link
      once, and allow DTS files to reference dtsi (and dts) files in other
      architectures that way.
      Original approach was to create these links under each architecture,
      but it lead to the problem of recursive symlinks.
      As a remedy, move the include link directories out of the architecture
      trees into a common location. At the same time, they can now share one
      directory and one dt-bindings/ link as well.

      scripts: Switch to more portable Perl shebang · cb77f0d6
      Kamil Rytarowski authored
      The default NetBSD package manager is pkgsrc and it installs Perl
      along other third party programs under custom and configurable prefix.
      The default prefix for binary prebuilt packages is /usr/pkg, and the
      Perl executable lands in /usr/pkg/bin/perl.
      This change switches "/usr/bin/perl" to "/usr/bin/env perl" as it's
      the most portable solution that should work for almost everybody.
      Perl's executable is detected automatically.
      This change switches -w option passed to the executable with more
      modern "use warnings;" approach. There is no functional change to the
      default behavior.
      While there, drop "require 5" from scripts/namespace.pl (Perl from 1994?).

      dtc: ensure #line directives don't consume data from the next line · 706b78f3
      Grant Likely authored
      Previously, the #line parsing regex ended with ({WS}+[0-9]+)?. The {WS}
      could match line-break characters. If the #line directive did not contain
      the optional flags field at the end, this could cause any integer data on
      the next line to be consumed as part of the #line directive parsing. This
      could cause syntax errors (i.e. #line parsing consuming the leading 0
      from a hex literal 0x1234, leaving x1234 to be parsed as cell data,
      which is a syntax error), or invalid compilation results (i.e. simply
      consuming literal 1234 as part of the #line processing, thus removing it
      from the cell data).
      Fix this by replacing {WS} with [ \t] so that it can't match line-breaks.
      Convert all instances of {WS}, even though the other instances should be
      irrelevant for any well-formed #line directive. This is done for
      consistency and ultimate safety.

      dtc: Update generated files to output from Bison 2.5 · 2a6a08ca
      Grant Likely authored
      This patch merely updates the generated dtc parser and lexer files to
      the output generated by Bison 2.5. The previous versions were generated
      from version 2.4.1. The only reason for this commit is to minimize the
      diff on the next commit which fixes a bug in the DTC #line directive
      parsing. Otherwise the Bison changes would be intermingled with the
      functional changes.

      Move dtc and libfdt sources from arch/powerpc/boot to scripts/dtc · 9fffb55f
      David Gibson authored
      The powerpc kernel always requires an Open Firmware like device tree
      to supply device information.  On systems without OF, this comes from
      a flattened device tree blob.  This blob is usually generated by dtc,
      a tool which compiles a text description of the device tree into the
      flattened format used by the kernel.  Sometimes, the bootwrapper makes
      small changes to the pre-compiled device tree blob (e.g. filling in
      the size of RAM).  To do this it uses the libfdt library.
      Because these are only used on powerpc, the code for both these tools
      is included under arch/powerpc/boot (these were imported and are
      periodically updated from the upstream dtc tree).
      However, the microblaze architecture, currently being prepared for
      merging to mainline also uses dtc to produce device tree blobs.  A few
      other archs have also mentioned some interest in using dtc.
      Therefore, this patch moves dtc and libfdt from arch/powerpc into
      scripts, where it can be used by any architecture.
      The vast bulk of this patch is a literal move, the rest is adjusting
      the various Makefiles to use dtc and libfdt correctly from their new
