  • 149ed3d40   change email address for Pali Rohár ... Browse Code »

    For security reasons I stopped using gmail account and kernel address is
    now up-to-date alias to my personal address.

    People periodically send me emails to address which they found in source
    code of drivers, so this change reflects state where people can contact
    me.

  • 7ed1c1901   tools: fix cross-compile var clobbering ... Browse Code »

    Currently a number of Makefiles break when used with toolchains that
    pass extra flags in CC and other cross-compile related variables (such
    as --sysroot).

    Thus we get this error when we use a toolchain that puts --sysroot in
    the CC var:

    ~/src/linux/tools$ make iio
    [snip]
    iio_event_monitor.c:18:10: fatal error: unistd.h: No such file or directory
    #include
    ^~~~~~~~~~

    This occurs because we clobber several env vars related to
    cross-compiling with lines like this:

    CC = $(CROSS_COMPILE)gcc

    Although this will point to a valid cross-compiler, we lose any extra
    flags that might exist in the CC variable, which can break toolchains
    that rely on them (for example, those that use --sysroot).

    This easily shows up using a Yocto SDK:

    $ . [snip]/sdk/environment-setup-cortexa8hf-neon-poky-linux-gnueabi

    $ echo $CC
    arm-poky-linux-gnueabi-gcc -march=armv7-a -mfpu=neon -mfloat-abi=hard
    -mcpu=cortex-a8
    --sysroot=[snip]/sdk/sysroots/cortexa8hf-neon-poky-linux-gnueabi

    $ echo $CROSS_COMPILE
    arm-poky-linux-gnueabi-

    $ echo ${CROSS_COMPILE}gcc
    krm-poky-linux-gnueabi-gcc

    Although arm-poky-linux-gnueabi-gcc is a cross-compiler, we've lost the
    --sysroot and other flags that enable us to find the right libraries to
    link against, so we can't find unistd.h and other libraries and headers.
    Normally with the --sysroot flag we would find unistd.h in the sdk
    directory in the sysroot:

    $ find [snip]/sdk/sysroots -path '*/usr/include/unistd.h'
    [snip]/sdk/sysroots/cortexa8hf-neon-poky-linux-gnueabi/usr/include/unistd.h

    The perf Makefile adds CC = $(CROSS_COMPILE)gcc if and only if CC is not
    already set, and it compiles correctly with the above toolchain.

    So, generalize the logic that perf uses in the common Makefile and
    remove the manual CC = $(CROSS_COMPILE)gcc lines from each Makefile.

    Note that this patch does not fix cross-compile for all the tools (some
    have other bugs), but it does fix it for all except usb and acpi, which
    still have other unrelated issues.

    I tested both with and without the patch on native and cross-build and
    there appear to be no regressions.

  • 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
