  • 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

  • 81760ea6a   crypto: cryptd - Add helpers to check whether a tfm is queued ... Browse Code »

    This patch adds helpers to check whether a given tfm is currently
    queued. This is meant to be used by ablk_helper and similar
    entities to ensure that no reordering is introduced because of
    requests queued in cryptd with respect to requests being processed
    in softirq context.

    The per-cpu queue length limit is also increased to 1000 in line
    with network limits.

  • 298c926c6   crypto: cryptd - Adding the AEAD interface type support to cryptd ... Browse Code »

    This patch adds AEAD support into the cryptd framework. Having AEAD
    support in cryptd enables crypto drivers that use the AEAD
    interface type (such as the patch for AEAD based RFC4106 AES-GCM
    implementation using Intel New Instructions) to leverage cryptd for
    asynchronous processing.

  • 0e1227d35   crypto: ghash - Add PCLMULQDQ accelerated implementation ... Browse Code »

    PCLMULQDQ is used to accelerate the most time-consuming part of GHASH,
    carry-less multiplication. More information about PCLMULQDQ can be
    found at:

    http://software.intel.com/en-us/articles/carry-less-multiplication-and-its-usage-for-computing-the-gcm-mode/

    Because PCLMULQDQ changes XMM state, its usage must be enclosed with
    kernel_fpu_begin/end, which can be used only in process context, the
    acceleration is implemented as crypto_ahash. That is, request in soft
    IRQ context will be defered to the cryptd kernel thread.
