  • 6736fde96   rfkill: fix rfkill_fop_read wait_event usage ... Browse Code »

    The code within wait_event_interruptible() is called with
    !TASK_RUNNING, so mustn't call any functions that can sleep,
    like mutex_lock().

    Since we re-check the list_empty() in a loop after the wait,
    it's safe to simply use list_empty() without locking.

    This bug has existed forever, but was only discovered now
    because all userspace implementations, including the default
    'rfkill' tool, use poll() or select() to get a readable fd
    before attempting to read.

  • b7bb11000   rfkill: copy the name into the rfkill struct ... Browse Code »

    Some users of rfkill, like NFC and cfg80211, use a dynamic name when
    allocating rfkill, in those cases dev_name(). Therefore, the pointer
    passed to rfkill_alloc() might not be valid forever, I specifically
    found the case that the rfkill name was quite obviously an invalid
    pointer (or at least garbage) when the wiphy had been renamed.

    Fix this by making a copy of the rfkill name in rfkill_alloc().

  • 36890997b   rfkill: Allow compile test of GPIO consumers if !GPIOLIB ... Browse Code »

    The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is
    not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer
    functionality only, can still be compiled if GPIOLIB is not enabled.

    Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where
    appropriate.

  • f7959e9c7   net: rfkill: gpio: make better use of gpiod API ... Browse Code »

    Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions)
    which appeared in v3.17-rc1, the gpiod_get* functions take an additional
    parameter that allows to specify direction and initial value for output.

    Furthermore there is devm_gpiod_get_optional which is designed to get
    optional gpios.

    Simplify driver accordingly.

    Note this makes error checking more strict because only -ENOENT is
    ignored when searching for the GPIOs which is good.

    They are dominated by the removal of the .owner field in platform

    Other than that, a few minor driver core and debugfs changes. There
    are some ath9k patches coming in through this tree that have been
    acked by the wireless maintainers as they relied on the debugfs
    changes.

  • 72daceb9a   net: rfkill: gpio: Add default GPIO driver mappings for ACPI ... Browse Code »

    The driver uses devm_gpiod_get_index(..., index) so that the index refers
    directly to the GpioIo resource under the ACPI device. The problem with
    this is that if the ordering changes we get wrong GPIOs.

    With ACPI 5.1 _DSD we can now use names instead to reference GPIOs
    analogous to Device Tree. However, we still have systems out there that do
    not provide _DSD at all. These systems must be supported as well.

    Luckily we now have acpi_dev_add_driver_gpios() that can be used to provide
    mappings for systems where _DSD is not provided and still take advantage of
    _DSD if it exists.

    This patch changes the driver to create default GPIO mappings if we are
    running on ACPI system.

    While there we can drop the indices completely and use devm_gpiod_get()
    with name instead.

  • 771bb3ddc   rfkill-gpio: Use gpio cansleep version ... Browse Code »

    If gpio controller requires waiting for read and write
    GPIO values, then we have to use the gpio cansleep api.
    Fix the rfkill_gpio_set_power which calls only the
    nonsleep version (causing kernel warning).
    There is no problem to use the cansleep version here
    because we are not in IRQ handler or similar context
    (cf rfkill_set_block).

  • 67235cbca   net: rfkill: move poll work to power efficient workqueue ... Browse Code »

    This patch moves the rfkill poll_work to the power efficient workqueue.
    This work does not have to be bound to the CPU that scheduled it, hence
    the selection of CPU that executes it would be left to the scheduler.
    Net result is that CPU idle times would be extended, resulting in power
    savings.

    This behaviour is enabled when CONFIG_WQ_POWER_EFFICIENT is selected.

    15) New "Heavy Hitter" qdisc, from Terry Lam.

    16) Significantly improve the IPSEC support in pktgen, from Fan Du.

    17) Allow ipv4 tunnels to cache routes, just like sockets. From Tom
    Herbert.

    address. From Christoph Paasch.

    hash, if provided. From Tom Herbert.
