  • 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

  • 0720a06a7   NLS: improve UTF8 -> UTF16 string conversion routine ... Browse Code »

    The utf8s_to_utf16s conversion routine needs to be improved. Unlike
    its utf16s_to_utf8s sibling, it doesn't accept arguments specifying
    the maximum length of the output buffer or the endianness of its
    16-bit output.

    This patch (as1501) adds the two missing arguments, and adjusts the
    only two places in the kernel where the function is called. A
    follow-on patch will add a third caller that does utilize the new
    capabilities.

    The two conversion routines are still annoyingly inconsistent in the
    way they handle invalid byte combinations. But that's a subject for a
    different patch.

  • 74675a585   NLS: update handling of Unicode ... Browse Code »

    This patch (as1239) updates the kernel's treatment of Unicode. The
    character-set conversion routines are well behind the current state of
    the Unicode specification: They don't recognize the existence of code
    points beyond plane 0 or of surrogate pairs in the UTF-16 encoding.

    The old wchar_t 16-bit type is retained because it's still used in
    lots of places. This shouldn't cause any new problems; if a
    conversion now results in an invalid 16-bit code then before it must
    have yielded an undefined code.

    Difficult-to-read names like "utf_mbstowcs" are replaced with more
    transparent names like "utf8s_to_utf16s" and the ordering of the
    parameters is rationalized (buffer lengths come immediate after the
    pointers they refer to, and the inputs precede the outputs).
    Fortunately the low-level conversion routines are used in only a few
    places; the interfaces to the higher-level uni2char and char2uni
    methods have been left unchanged.

    It's possible for character sets to require a multi-byte null
    string terminator. Add a helper function that determines the size
    of the null terminator at runtime.

  • b9ec0339d   add consts where appropriate in fs/nls/* ... Browse Code »

    Add const modifiers to a few struct nls_table's member pointers in
    include/linux/nls.h and adds a lot of const's in fs/nls/*.c files.

    Resulting changes as visible by size:

    text data bss dec hex filename
    113612 481216 2368 597196 91ccc nls.org/built-in.o
    593548 3296 288 597132 91c8c nls/built-in.o

    Apparently compiler managed to optimize code a bit better
    because of const-ness.

    No other changes are made.

    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!
