  • 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

  • a26c5fd76   nl802154: add support for security layer ... Browse Code »

    This patch adds support for accessing mac802154 llsec implementation
    over nl802154. I added for a new Kconfig entry to provide this
    functionality CONFIG_IEEE802154_NL802154_EXPERIMENTAL. This interface is
    still in development. It provides to change security parameters and
    add/del/dump entries of security tables. Later we can add also a get to
    get an entry by unique identifier.

  • c91208d81   ieee802154: add ack request default handling ... Browse Code »

    This patch introduce a new mib entry which isn't part of 802.15.4 but
    useful as default behaviour to set the ack request bit or not if we
    don't know if the ack request bit should set. This is currently used for
    stacks like IEEE 802.15.4 6LoWPAN.

    This code is based on commit 6bab2e19c5ffd
    ("cfg80211: pass name_assign_type to rdev_add_virtual_intf()")

    This will expose in sysfs whether the ifname of a IEEE-802.15.4
    device is set by userspace or generated by the kernel.
    We are using two types of name_assign_types
    o NET_NAME_ENUM: Default interface name provided by kernel
    o NET_NAME_USER: Interface name provided by user.

  • 4a9a816a4   cfg802154: convert deprecated iface add and del ... Browse Code »

    This patch removes the wpan_phy callbacks for add and del an interface
    on a phy. Instead we introduce deprecated cfg802154 callbacks for this.
    Furthermore we introduce a new netlink interface nl802154 which use
    different callbacks. The deprecated function is to have a backwards
    compatibility with the current netlink interface.
