  • 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

  • 02e2a5bfe   mac: validate mac_partition is within sector ... Browse Code »

    If md->signature == MAC_DRIVER_MAGIC and md->block_size == 1023, a single
    512 byte sector would be read (secsize / 512). However the partition
    structure would be located past the end of the buffer (secsize % 512).

  • 582940508   block: Replace strnicmp with strncasecmp ... Browse Code »

    The kernel used to contain two functions for length-delimited,
    case-insensitive string comparison, strnicmp with correct semantics
    and a slightly buggy strncasecmp. The latter is the POSIX name, so
    strnicmp was renamed to strncasecmp, and strnicmp made into a wrapper
    for the new strncasecmp to avoid breaking existing users.

    To allow the compat wrapper strnicmp to be removed at some point in
    the future, and to avoid the extra indirection cost, do
    s/strnicmp/strncasecmp/g.

  • 06004e6ee   block/partitions/mac.c: obey the state->limit constraint ... Browse Code »

    It isn't necessary to read the information of partitions whose number is
    equal and more than state->limit since only maximum state->limit
    partitions will be added inside rescan_partitions().

    That is also what other kind of partitions are doing.
