H A D | posix-timers.h | 6fec64e1 Tue Jun 26 08:21:31 CDT 2018 Thomas Gleixner <tglx@linutronix.de> posix-timers: Make forward callback return s64
The posix timer ti_overrun handling is broken because the forwarding functions can return a huge number of overruns which does not fit in an int. As a consequence timer_getoverrun(2) and siginfo::si_overrun can turn into random number generators.
As a first step to address that let the timer_forward() callbacks return the full 64 bit value.
Cast it to (int) temporarily until k_itimer::ti_overrun is converted to 64bit and the conversion to user space visible values is sanitized.
