* rfkill: fix rfkill_fop_read wait_event usageJohannes Berg2016-01-261-12/+4
| | | | | | | | | | | | | | | | | | | 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.

* rfkill: copy the name into the rfkill structJohannes Berg2015-12-101-3/+3
| | | | | | | | | | | | | 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(). Cc: stable@vger.kernel.org Signed-off-by: Johannes Berg <johannes.berg@intel.com>

* | rfkill: Allow compile test of GPIO consumers if !GPIOLIBGeert Uytterhoeven2015-08-131-1/+2
|/ | | | | | | | | | | | | 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.

* net: rfkill: gpio: make better use of gpiod APIUwe Kleine-König2015-05-291-14/+10
| | | | | | | | | | | | | | | | | 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.

* | net: rfkill: gpio: Add default GPIO driver mappings for ACPIMika Westerberg2014-11-041-3/+15
|/ | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This benefits processes that have very many mostly idle sockets, which is quite common. From Eric Dumazet. 10) Use up to 32K for page fragment allocations, with fallbacks to smaller sizes when higher order page allocations fail. Benefits are a) less segments for driver to process b) less calls to page allocator c) less waste of space. From Eric Dumazet. 11) Allow GRO to be used on GRE tunnels, from Eric Dumazet. 12) VXLAN device driver, one way to handle VLAN issues such as the limitation of 4096 VLAN IDs yet still have some level of isolation. From Stephen Hemminger. 13) As usual there is a large boatload of driver changes, with the scale perhaps tilted towards the wireless side this time around.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prevent unnecessary rfkill event generation when the state has not actually changed. These events have to be delivered to relevant userspace processes, causing these processes to wake up and do something while they could as well have slept. This obviously results in more CPU usage, longer time-to-sleep-again and therefore higher power consumption.

* / workqueue: use mod_delayed_work() instead of cancel + queueTejun Heo2012-08-141-2/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert delayed_work users doing cancel_delayed_work() followed by queue_delayed_work() to mod_delayed_work(). Most conversions are straight-forward. Ones worth mentioning are, * drivers/edac/edac_mc.c: edac_mc_workq_setup() converted to always use mod_delayed_work() and cancel loop in edac_mc_reset_delay_period() is dropped. * drivers/platform/x86/thinkpad_acpi.c: No need to remember whether watchdog is active or not. @fan_watchdog_active and related code dropped. * drivers/power/charger-manager.c: Seemingly a lot of delayed_work_pending() abuse going on here. [delayed_]work_pending() are unsynchronized and racy when used like this. I converted one instance in fullbatt_handler(). Please conver the rest so that it invokes workqueue APIs for the intended target state rather than trying to game work item pending state transitions. e.g. if timer should be modified - call mod_delayed_work(), canceled - call cancel_delayed_work[_sync](). * drivers/thermal/thermal_sys.c: thermal_zone_device_set_polling() simplified. Note that round_jiffies() calls in this function are meaningless. round_jiffies() work on absolute jiffies not delta delay used by delayed_work. v2: Tomi pointed out that __cancel_delayed_work() users can't be safely converted to mod_delayed_work(). They could be calling it from irq context and if that happens while delayed_work_timer_fn() is running, it could deadlock. __cancel_delayed_work() users are dropped.

* rfkill: Add the capability to switch all devices of all type in ↵Alex Hung2012-06-061-1/+1
| | | | | | | | | | | | | | __rfkill_switch_all(). __rfkill_switch_all() switches the state of devices of a given type; however, it does not switch devices of all type (RFKILL_TYPE_ALL). As a result, it ignores the keycode "KEY_RFKILL" from another module, i.e. eeepc-wmi. This fix is to make __rfkill_switch_all() to be able to switch not only devices of a given type but also all devices. Signed-off-by: Alex Hung <alex.hung@canonical.com> Signed-off-by: John W.
