2017-06-30posix-timers: Use get_timespec64() and put_timespec64()Deepa Dinamani
Usage of these apis and their compat versions makes the syscalls: clock_gettime, clock_settime, clock_getres and their compat implementations simpler. This is a preparatory patch to isolate data conversions to struct timespec64 at userspace boundaries. This helps contain the changes needed to transition to new y2038 safe types.

2017-06-25time: introduce {get,put}_itimerspec64Deepa Dinamani
As we change the user space type for the timerfd and posix timer functions to newer data types, we need some form of conversion helpers to avoid duplicating that logic.

2017-06-25time: add get_timespec64 and put_timespec64Deepa Dinamani
Add helper functions to convert between struct timespec64 and struct timespec at userspace boundaries. This is a preparatory patch to use timespec64 as the basic type internally in the kernel as timespec is not y2038 safe on 32 bit systems. The patch helps the cause by containing all data conversions at the userspace boundaries within these functions.

2017-06-14hrtimer: Move copyout of remaining time to do_nanosleep()Al Viro
The hrtimer nanosleep() implementation can be simplified by moving the copy out of the remaining time to do_nanosleep() which is shared between the real nanosleep function and the restart function. The pointer to the timespec64 which is updated is already stored in the restart block at the call site, so the seperate handling of nanosleep and restart function can be avoided.

2017-06-12posix-timers: Handle relative posix-timers correctlyThomas Gleixner
The recent rework of the posix timer internals broke the magic posix mechanism, which requires that relative timers are not affected by modifications of the underlying clock. That means relative CLOCK_REALTIME timers cannot use CLOCK_REALTIME, because that can be set and adjusted. The underlying hrtimer switches the clock for these timers to CLOCK_MONOTONIC. That still works, but reading the remaining time of such a timer has been broken in the rework. The old code used the hrtimer internals directly and avoided the posix clock callbacks. Now common_timer_get() uses the underlying kclock->timer_get() callback, which is still CLOCK_REALTIME based. So the remaining time of such a timer is calculated against the wrong time base. Handle it by switching the k_itimer->kclock pointer according to the resulting hrtimer mode. k_itimer->it_clock still contains CLOCK_REALTIME because the timer might be set with ABSTIME later and then it needs to switch back to the realtime posix clock implementation.

2017-06-12posix-timers: Zero out oldval itimerspecThomas Gleixner

2017-06-12posix-timers: Fix inverted SIGEV_NONE logic in common_timer_get()Thomas Gleixner
The refactoring of the posix-timer core to allow better code sharing introduced inverted logic vs. SIGEV_NONE timers in common_timer_get(). That causes hrtimer_forward() to be called on active timers, which rightfully triggers the warning hrtimer_forward(). Make sig_none what it says: signal mode == SIGEV_NONE.

The only user of this facility is ptp_clock, which does not implement any of those functions. Remove them to prevent accidental users. Especially the interval timer interfaces are now more or less impossible to implement because the necessary infrastructure has been confined to the core code. Aside of that it's really complex to make these callbacks implemented according to spec as the alarm timer implementation demonstrates. If at all then a nanosleep callback might be a reasonable extension. For now keep just what ptp_clock needs.
