2018-03-17rtc: Factor out the RTC range validation into rtc_valid_range()Baolin Wang
The RTC range validation code can be factored into rtc_valid_range() function to avoid duplicate code. Signed-off-by: Baolin Wang <baolin.wang@linaro.org> Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2018-03-17rtc: Add RTC rangeAlexandre Belloni
Add a way for drivers to inform the core of the supported date/time range. The core can then check whether the date/time or alarm is in the range before calling ->set_time, ->set_mmss or ->set_alarm. It returns -ERANGE when the time is out of range. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>

2018-03-17rtc: isl1208: enable interrupt after context preparationMichael Grzeschik
The interrupt handler got enabled very early. If the interrupt cause is triggering immediately before the context is fully prepared. This can lead to undefined behaviour.

2018-03-17rtc: cros-ec: return -ETIME when refused to set alarms in the pastJeffy Chen
Since accessing a Chrome OS EC based rtc is a slow operation, there is a race window where if the alarm is set for the next second and the second ticks over right before calculating the alarm offset. In this case the current driver is setting a 0-second alarm, which would be considered as disabling alarms by the EC(EC_RTC_ALARM_CLEAR). This breaks, e.g., hwclock which relies on RTC_UIE_ON -> rtc_update_irq_enable(), which sets a 1-second alarm and expects it to fire an interrupt. So return -ETIME when the alarm is in the past, follow __rtc_set_alarm().

This is currently one of few remaining warnings for a 4.14.y randconfig build, so it would be good to also have it backported at least to that version. Older versions have more randconfig warnings, so we might not care. I had not noticed this earlier, because one patch in my randconfig test tree removes the '-ffreestanding' option on x86-32, and that avoids the warning. The -ffreestanding flag was originally global but moved into arch/i386 by Andi Kleen in commit 6edfba1b33c7 ("[PATCH] x86_64: Don't define string functions to builtin") as a 'temporary workaround'. Like many temporary hacks, this turned out to be rather long-lived, from all I can tell we still need a simple fix to asm/string_32.h before it can be removed, but I'm not sure about how to best do that.

In preparation to enabling -Wvla, remove VLA. In this particular case use macro ARRAY_SIZE so the length of array _bo_ can be computed at preprocessing time. The use of stack Variable Length Arrays needs to be avoided, as they can be a vector for stack exhaustion, which can be both a runtime bug or a security flaw. Also, in general, as code evolves it is easy to lose track of how big a VLA can get. Thus, we can end up having runtime failures that are hard to debug. Also, fixed as part of the directive to remove all VLAs from the kernel: https://lkml.org/lkml/2018/3/7/621 Signed-off-by: Gustavo A. R.

2018-03-16clk: versatile: Remove WARNs in ->round_rate()Brian Starkey
clk_round_rate() is intended to be used to round a given clock rate to the closest one achievable by the actual clock. This implies that the input to clk_round_rate() is expected to be unachievable - and such cases shouldn't be treated as exceptional. To reflect this, remove the WARN_ONs which trigger when an unachievable clock rate is passed to vexpress_osc_round_rate().

2018-03-16clk: versatile: add min/max rate boundaries for vexpress osc clockSudeep Holla
Clock framework has a provider API(clk_hw_set_rate_range) to set the min/max rate of a clock. Use the same to set the boundaries for the vexpress osc clock.
