  • 21698fd57   parport_pc: fix find_superio io compare code, should use equal test. ... Browse Code »

    In the original code before 181bf1e815a2 the loop was continuing until
    it finds the first matching superios[i].io and p->base.
    But after 181bf1e815a2 the logic changed and the loop now returns the
    pointer to the first mismatched array element which is then used in
    get_superio_dma() and get_superio_irq() and thus returning the wrong
    value.
    Fix the condition so that it now returns the correct pointer.

    "Here is the bit set of char/misc drivers for 4.19-rc1

    There is a lot here, much more than normal, seems like everyone is
    writing new driver subsystems these days... Anyway, major things here
    are:

    - new FSI driver subsystem, yet-another-powerpc low-level hardware
    bus

    - gnss, finally an in-kernel GPS subsystem to try to tame all of the
    crazy out-of-tree drivers that have been floating around for years,
    combined with some really hacky userspace implementations. This is
    only for GNSS receivers, but you have to start somewhere, and this
    is great to see.

    Other than that, there are new slimbus drivers, new coresight drivers,
    new fpga drivers, and loads of DT bindings for all of these and
    existing drivers.

    All of these have been in linux-next for a while with no reported
    issues"

    Pull timer updates from Thomas Gleixner:
    "Yet another big pile of changes:

    - More year 2038 work from Arnd slowly reaching the point where we
    need to think about the syscalls themself.

    - A new timer function which allows to conditionally (re)arm a timer
    only when it's either not running or the new expiry time is sooner
    than the armed expiry time. This allows to use a single timer for
    multiple timeout requirements w/o caring about the first expiry
    time at the call site.

    - A new NMI safe accessor to clock real time for the printk timestamp
    work. Can be used by tracing, perf as well if required.

    - A large number of timer setup conversions from Kees which got
    collected here because either maintainers requested so or they
    simply got ignored. As Kees pointed out already there are a few
    trivial merge conflicts and some redundant commits which was
    unavoidable due to the size of this conversion effort.

    - Avoid a redundant iteration in the timer wheel softirq processing.

    - Provide a mechanism to treat RTC implementations depending on their
    hardware properties, i.e. don't inflict the write at the 0.5
    seconds boundary which originates from the PC CMOS RTC to all RTCs.
    No functional change as drivers need to be updated separately.

    really exciting"

  • 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

  • c8fc074dd   Annotate hardware config module parameters in drivers/parport/ ... Browse Code »

    When the kernel is running in secure boot mode, we lock down the kernel to
    prevent userspace from modifying the running kernel image. Whilst this
    includes prohibiting access to things like /dev/mem, it must also prevent
    access by means of configuring driver modules in such a way as to cause a
    device to access or modify the kernel image.

    To this end, annotate module_param* statements that refer to hardware
    configuration and indicate for future reference what type of parameter they
    specify. The parameter parser in the core sees this information and can
    skip such parameters with an error message if the kernel is locked down.
    The module initialisation then runs as normal, but just sees whatever the
    default values for those parameters is.

    Note that we do still need to do the module initialisation because some
    drivers have viable defaults set in case parameters aren't specified and
    some drivers support automatic configuration (e.g. PNP or PCI) in addition
    to manually coded parameters.

    This patch annotates drivers in drivers/parport/.

    Usually every parallel port will have a single pardev registered with
    it. But ppdev driver is an exception. This userspace parallel port
    driver allows to create multiple parrallel port devices for a single
    parallel port. And as a result we were having a nice warning like:
    "sysctl table check failed:
    /dev/parport/parport0/devices/ppdev0/timeslice Sysctl already exists"

    Use the same logic as used in parport_register_device() and register
    the proc files only once for each parallel port.

    Now that %z is standartised in C99 there is no reason to support %Z.
    Unlike %L it doesn't even make format strings smaller.

    Use BUILD_BUG_ON in a couple ATM drivers.

    In case anyone didn't notice lib/vsprintf.o is about half of SLUB which
    is in my opinion is quite an achievement. Hopefully this patch inspires
    someone else to trim vsprintf.c more.
