[PATCH] prevent timespec/timeval to ktime_t overflow

2006-09-06T18:00:02Z

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.

[PATCH] hrtimers: remove DEFINE_KTIME and ktime_to_clock_t()

2006-03-26T16:57:03Z

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. Signed-off-by: Roman Zippel Acked-by: Ingo Molnar Acked-by: Thomas Gleixner Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] hrtimer: fix multiple macro argument expansion

2006-02-15T23:32:22Z

For two macros the arguments were expanded twice, change them to inline functions to avoid it. Signed-off-by: Roman Zippel Acked-by: Ingo Molnar Acked-by: Thomas Gleixner Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] hrtimers: add back lost credit lines

2006-02-01T16:53:13Z

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. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[hrtimer] Change resolution storage to ktime_t format

2006-01-12T10:36:14Z

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. Signed-off-by: Thomas Gleixner

[PATCH] hrtimer: hrtimer core code

2006-01-10T16:01:37Z

hrtimer subsystem core. It is initialized at bootup and expired by the timer interrupt, but is otherwise not utilized by any other subsystem yet. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] hrtimer: introduce ktime_t time format

2006-01-10T16:01:37Z

- 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. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
