  • 1bd9a4680   kbuild: get rid of kernel/ prefix from in-tree modules.{order,builtin} ... Browse Code »

    Removing the 'kernel/' prefix will make our life easier because we can
    simply do 'cat modules.order' to get all built modules with full paths.

    Currently, we parse the first line of '*.mod' files in $(MODVERDIR).
    Since we have duplicated functionality here, I plan to remove MODVERDIR
    entirely.

    In fact, modules.order is generated also for external modules in a
    broken format. It adds the 'kernel/' prefix to the absolute path of
    the module, like this:

    kernel//path/to/your/external/module/foo.ko

    This is fine for now since modules.order is not used for external
    modules. However, I want to sanitize the format everywhere towards
    the goal of removing MODVERDIR.

    We cannot change the format of installed module.{order,builtin}.
    So, 'make modules_install' will add the 'kernel/' prefix while copying
    them to $(MODLIB)/.

  • 051f278e9   kbuild: replace KBUILD_SRCTREE with boolean building_out_of_srctree ... Browse Code »

    Commit 25b146c5b8ce ("kbuild: allow Kbuild to start from any directory")
    deprecated KBUILD_SRCTREE.

    It is only used in tools/testing/selftest/ to distinguish out-of-tree
    build. Replace it with a new boolean flag, building_out_of_srctree.

    I also replaced the conditional ($(srctree),.) because the next commit
    will allow an absolute path to be used for $(srctree) even when building
    in the source tree.

  • a9a49c2ad   kbuild: use $(srctree) instead of KBUILD_SRC to check out-of-tree build ... Browse Code »

    KBUILD_SRC was conventionally used for some different purposes:
    [1] To remember the source tree path
    [2] As a flag to check if sub-make is already done
    [3] As a flag to check if Kbuild runs out of tree

    For [1], we do not need to remember it because the top Makefile
    can compute it by $(realpath $(dir $(lastword $(MAKEFILE_LIST))))

    [2] has been replaced with self-commenting 'sub_make_done'.

    For [3], we can distinguish in-tree/out-of-tree by comparing
    $(srctree) and '.'

    This commit converts [3] to prepare for the KBUILD_SRC removal.

  • b24413180   License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Browse Code »

    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

  • bc081dd6e   kbuild: generate modules.builtin ... Browse Code »

    To make it easier for module-init-tools and scripts like mkinitrd to
    distinguish builtin and missing modules, install a modules.builtin file
    listing all builtin modules. This is done by generating an additional
    config file (tristate.conf) with tristate options set to uppercase 'Y'
    or 'M'. If we source that config file, the builtin modules appear in
    obj-Y.
