  • 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

  • cabd91c3b   parisc: avoid undefined shift in cnv_float.h ... Browse Code »

    The attached change fixes a float conversion problem found running the
    GCC testsuite with GCC configured with --with-arch=2.0.

    The actual problem occurs for an exponent value of 63. This is the
    maximum exponent value that can be passed. This causes a left shift by
    32 in the else hunk of the macro. This causes undefined behavior and the
    wrong value is returned for dresultB. The fix is the check "exponent <<
    SGL_EXP_LENGTH" to val, so that sgl_value is not modified.

  • 497888cf6   treewide: fix potentially dangerous trailing ';' in #defined values/expressions ... Browse Code »

    All these are instances of
    #define NAME value;
    or
    #define NAME(params_opt) value;

    These of course fail to build when used in contexts like
    if(foo $OP NAME)
    while(bar $OP NAME)
    and may silently generate the wrong code in contexts such as
    foo = NAME + 1; /* foo = value; + 1; */
    bar = NAME - 1; /* bar = value; - 1; */
    baz = NAME & quux; /* baz = value; & quux; */

    Reported on comp.lang.c,
    Message-ID:
    Initial analysis of the dangers provided by Keith Thompson in that thread.

    There are many more instances of more complicated macros having unnecessary
    trailing semicolons, but this pile seems to be all of the cases of simple
    values suffering from the problem. (Thus things that are likely to be found
    in one of the contexts above, more complicated ones aren't.)

  • 9a39e273d   kbuild: fix up CFLAGS usage ... Browse Code »

    Only in very rare cases is it needed to change CFLAGS
    outside of arch/*/Makefile.
    Fix up all wrong cases - in most cases
    the use of EXTRA_CFLAGS is the only thing needed.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
