  • 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

  • 2492218c6   sparc32: unaligned memory access (MNA) trap handler bug ... Browse Code »

    Since commit f0e98c387e61de00646be31fab4c2fa0224e1efb ("[SPARC]: Fix
    link errors with gcc-4.3") the MNA trap handler does not emulate
    stores to unaligned addresses correctly. MNA operation from both
    kernel and user space are affected.

    A typical effect of this bug is nr_frags in skbs are overwritten
    during buffer copying/checksum-calculation, or maximally 6 bytes
    of data in the network buffer will be overwitten with garbage.

  • d670bd4f8   sparc: prepare kernel/ for unification ... Browse Code »

    o sparc32 files with identical names to sparc64 renamed to _32.S
    o introduced a few Kconfig helpers to simplify Makefile logic
    o refactored Makefile to prepare for unification
    - use obj-$(CONFIG_SPARC32) for sparc32 specific files
    - use _$(BITS) for files where sparc64 has a _64 variant
    - sparc64 directly include a few files where sparc32 builds them,
    refer to these files directly (no BITS)
    - sneaked in -Werror as used by sparc64
    o modified sparc/Makefile to use the new names for head/init_task
