  • 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

  • 2c92057e4   hfsplus: add necessary declarations for POSIX ACLs support ... Browse Code »

    This patchset implements POSIX ACLs support in hfsplus driver.

    Mac OS X beginning with version 10.4 ("Tiger") support NFSv4 ACLs, which
    are part of the NFSv4 standard. HFS+ stores ACLs in the form of
    specially named extended attributes (com.apple.system.Security).

    But this patchset doesn't use "com.apple.system.Security" extended
    attributes. It implements support of POSIX ACLs in the form of extended
    attributes with names "system.posix_acl_access" and
    "system.posix_acl_default". These xattrs are treated only under Linux.
    POSIX ACLs doesn't mean something under Mac OS X. Thereby, this patch
    set provides opportunity to use POSIX ACLs under Linux on HFS+
    filesystem.

    This patch:

    Add CONFIG_HFSPLUS_FS_POSIX_ACL kernel configuration option, DBG_ACL_MOD
    debugging flag and acl.h file with declaration of essential functions
    for support POSIX ACLs in hfsplus driver.
