  • 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

  • 846e344eb   net/smc: add receive timeout check ... Browse Code »

    The SMC receive function currently lacks a timeout check under the
    condition that no data were received and no data are available. This
    patch adds such a check.

  • c3edc4010   sched/headers: Move task_struct::signal and task_struct::sighand types and acces… ... Browse Code »

    …sors into <linux/sched/signal.h>

    task_struct::signal and task_struct::sighand are pointers, which would normally make it
    straightforward to not define those types in sched.h.

    That is not so, because the types are accompanied by a myriad of APIs (macros and inline
    functions) that dereference them.

    Split the types and the APIs out of sched.h and move them into a new header, <linux/sched/signal.h>.

    With this change sched.h does not know about 'struct signal' and 'struct sighand' anymore,
    trying to put accessors into sched.h as a test fails the following way:

    ./include/linux/sched.h: In function ‘test_signal_types’:
    ./include/linux/sched.h:2461:18: error: dereferencing pointer to incomplete type ‘struct signal_struct’
    ^

    This reduces the size and complexity of sched.h significantly.

    Update all headers and .c code that relied on getting the signal handling
    functionality from <linux/sched.h> to include <linux/sched/signal.h>.

    The list of affected files in the preparatory patch was partly generated by
    grepping for the APIs, and partly by doing coverage build testing, both
    all[yes|mod|def|no]config builds on 64-bit and 32-bit x86, and an array of
    cross-architecture builds.

    Nevertheless some (trivial) build breakage is still expected related to rare
    Kconfig combinations and in-flight patches to various kernel code, but most
    of it should be handled by this patch.
