  • 5ee254ef7   tools: fix cross-compile var clobbering ... Browse Code »

    commit 7ed1c1901fe52e6c5828deb155920b44b0adabb1 upstream.

    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.

    commit 297d6b6e56c2977fc504c61bbeeaa21296923f89 upstream.

    While reading in more than one block (50) of KVP records, the allocation
    goes per block, but the reads used the total number of allocated records
    (without resetting the pointer/stream). This causes the records buffer to
    overrun when the refresh reads more than one block over the previous
    capacity (e.g. reading more than 100 KVP records whereas the in-memory
    database was empty before).

    Fix this by reading the correct number of KVP records from file each time.

  • 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

  • ea81fdf09   Tools: hv: vss: Skip freezing filesystems backed by loop ... Browse Code »

    Since a loop device is backed by a file, a backup will already result in
    its parent filesystem being frozen. It's sufficient to just freeze the
    parent filesystem, so we can skip the loop device.

    This avoids a situation where a loop device and its parent filesystem are
    both frozen and then thawed out of order. For example, if the loop device
    is enumerated first, we would thaw it while its parent filesystem is still
    frozen. The thaw operation fails and the loop device remains frozen.
