mac80211: don't open-code LED manipulations

2021-06-23T09:29:12Z

We shouldn't open-code led_trigger_blink() or led_trigger_event(), use them instead of badly open-coding them. This also fixes the locking, led_trigger_blink() and led_trigger_event() now use read_lock_irqsave().

leds: triggers: let struct led_trigger::activate() return an error code

2018-07-05T21:21:10Z

Given that activating a trigger can fail, let the callback return an indication. This prevents to have a trigger active according to the "trigger" sysfs attribute but not functional. All users are changed accordingly to return 0 for now. There is no intended change in behaviour. Signed-off-by: Uwe Kleine-König Acked-by: Pavel Machek Signed-off-by: Jacek Anaszewski

mac80211: Convert timers to use timer_setup()

2017-11-20T15:55:11Z

In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly.

mac80211: fix throughput LED trigger

2015-05-11T17:16:04Z

As I was testing with hwsim, I missed that my previous commit to make LED work depend on activation broke the code because I missed removing the old trigger struct and some code was still using it, now erroneously, causing crashes. Fix this by always using the correct struct. Reported-by: Felix Fietkau Tested-by: Felix Fietkau Signed-off-by: Johannes Berg

mac80211: make LED triggering depend on activation

2015-05-05T12:21:56Z

When LED triggers are compiled in, but not used, mac80211 will still call them to update the status. This isn't really a problem for the assoc and radio ones, but the TX/RX (and to a certain extend TPT) ones can be called very frequently (for every packet.) In order to avoid that when they're not used, track their activation and call the corresponding trigger (and in the TPT case, account for throughput) only when the trigger is actually used by an LED. Additionally, make those trigger functions inlines since theyre only used once in the remaining code. Signed-off-by: Johannes Berg

mac80211: make LED trigger names const

2015-05-05T12:21:55Z

This is just a code cleanup, make the LED trigger names const as they're not expected to be modified by drivers. Signed-off-by: Johannes Berg

mac80211: use oneshot blink API for LED triggers

2013-08-01T08:48:49Z

Change mac80211 LED trigger code to use the generic led_trigger_blink_oneshot() API for transmit and receive activity indication. This gives a better feedback to the user, as with the new API each activity event results in a visible blink, while a constant traffic results in a continuous blink at constant rate.

leds: Rename led_brightness_set() to led_set_brightness()

2012-07-23T23:52:34Z

Rename leds external interface led_brightness_set() to led_set_brightness(). This is the second phase of the change to reduce confusion between the leds internal and external interfaces that set brightness. With this change, now the external interface is led_set_brightness(). The first phase renamed the internal interface led_set_brightness() to __led_set_brightness(). There are no changes to the interface implementations.

net: Add export.h for EXPORT_SYMBOL/THIS_MODULE to non-modules

2011-10-31T23:30:30Z

These files are non modular, but need to export symbols using the macros now living in export.h -- call out the include so that things won't break when we remove the implicit presence of module.h from everywhere. Signed-off-by: Paul Gortmaker
