  • 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

  • 5ca636b98   crypto: 842 - remove WARN inside printk ... Browse Code »

    Remove the WARN() from the beN_to_cpu macro, which is used as a param to a
    pr_debug() call. With a certain kernel config, this printk-in-printk
    results in the no_printk() macro trying to recursively call the
    no_printk() macro, and since macros can't recursively call themselves
    a build error results.

  • ea0b3984c   crypto: 842 - Add CRC and validation support ... Browse Code »

    This patch adds CRC generation and validation support for nx-842.
    Add CRC flag so that nx842 coprocessor includes CRC during compression
    and validates during decompression.

    Also changes in 842 SW compression to append CRC value at the end
    of template and checks during decompression.

  • 2da572c95   lib: add software 842 compression/decompression ... Browse Code »

    Add 842-format software compression and decompression functions.
    Update the MAINTAINERS 842 section to include the new files.

    The 842 compression function can compress any input data into the 842
    compression format. The 842 decompression function can decompress any
    standard-format 842 compressed data - specifically, either a compressed
    data buffer created by the 842 software compression function, or a
    compressed data buffer created by the 842 hardware compressor (located
    in PowerPC coprocessors).

    The 842 compressed data format is explained in the header comments.

    This is used in a later patch to provide a full software 842 compression
    and decompression crypto interface.
