• 96dd7421a   [PATCH] prevent timespec/timeval to ktime_t overflow ... Browse Code »

  Frank v. Waveren pointed out that on 64bit machines the timespec to
  ktime_t conversion might overflow. This is also true for timeval to
  ktime_t conversions. This breaks a "sleep inf" on 64bit machines.

  While a timespec/timeval with tx.sec = MAX_LONG is valid by specification
  the internal representation of ktime_t is based on nanoseconds. The
  conversion of seconds to nanoseconds overflows for seconds values >=
  (MAX_LONG / NSEC_PER_SEC).

  Check the seconds argument to the conversion and limit it to the maximum
  time which can be represented by ktime_t.

  Now that it_real_value is gone, the last user of DEFINE_KTIME and
  ktime_to_clock_t are also gone, so remove it before someone starts using it
  again.

  At some point we added credits to people who actively helped to bring
  k/hr-timers along. This was lost in the big code revamp. Add it back.

  Change the storage format of the per base resolution to ktime_t to
  make it easier accessible in the hrtimers code.

  Change the resolution from (NSEC_PER_SEC/HZ) to TICK_NSEC as Roman
  pointed out. TICK_NSEC is closer to the real resolution.

  - introduce ktime_t: nanosecond-resolution time format.

  - eliminate the plain s64 scalar type, and always use the union.
  This simplifies the arithmetics. Idea from Roman Zippel.
