thermal: core: Fix use-after-free in thermal_zone_device_unregister()

2020-09-04T09:52:54+00:00

The user-after-free bug in thermal_zone_device_unregister() is reported by KASAN. It happens because struct thermal_zone_device is released during of device_unregister() invocation, and hence the "tz" variable shouldn't be touched by thermal_notify_tz_delete(tz->id).

Currently driver is suppressing the negative temperature readings from the vadc. Consumers of the thermal zones need to read the negative temperature too. Don't suppress the readings.

thermal: ti-soc-thermal: Fix bogus thermal shutdowns for omap4430

2020-09-04T09:52:46+00:00

We can sometimes get bogus thermal shutdowns on omap4430 at least with droid4 running idle with a battery charger connected: thermal thermal_zone0: critical temperature reached (143 C), shutting down Dumping out the register values shows we can occasionally get a 0x7f value that is outside the TRM listed values in the ADC conversion table. And then we get a normal value when reading again after that. Reading the register multiple times does not seem help avoiding the bogus values as they stay until the next sample is ready. Looking at the TRM chapter "18.4.10.2.3 ADC Codes Versus Temperature", we should have values from 13 to 107 listed with a total of 95 values. But looking at the omap4430_adc_to_temp array, the values are off, and the end values are missing. And it seems that the 4430 ADC table is similar to omap3630 rather than omap4460. Let's fix the issue by using values based on the omap3630 table and just ignoring invalid values. Compared to the 4430 TRM, the omap3630 table has the missing values added while the TRM table only shows every second value. Note that sometimes the ADC register values within the valid table can also be way off for about 1 out of 10 values. But it seems that those just show about 25 C too low values rather than too high values. So those do not cause a bogus thermal shutdown.

thermal: don't make THERMAL_NETLINK 'default y'

2020-08-07T16:05:02+00:00

We just don't do that. "default y" is for things that are needed for compatibility (when an old feature is made unconditional), or for things that are basically part of the infrastructure of a platform. And it can possibly be used for questions that don't enable code on their own, but are used to enable or disable a whole slew of other questions. A new feature that people aren't using is never 'default y', unless it cures cancer or ends world hunger. Signed-off-by: Linus Torvalds
