hrtimer: Get rid of hrtimer_get_res()

2015-04-22T15:06:49+00:00

The resolution is directly accessible now. So its simpler just to fill in the values of the timespec and be done with it. Text size reduction (combined with "hrtimer: Get rid of the resolution field in hrtimer_clock_base"): x8664 -61, i386 -221, ARM -60, power64 -48 Signed-off-by: Thomas Gleixner Acked-by: Peter Zijlstra Cc: Preeti U Murthy Cc: Viresh Kumar Cc: Marcelo Tosatti Cc: Frederic Weisbecker Link: http://lkml.kernel.org/r/20150414203500.879888080@linutronix.de Signed-off-by: Thomas Gleixner

posix-timers: Fix stack info leak in timer_create()

2014-10-25T08:43:15+00:00

If userland creates a timer without specifying a sigevent info, we'll create one ourself, using a stack local variable. Particularly will we use the timer ID as sival_int. But as sigev_value is a union containing a pointer and an int, that assignment will only partially initialize sigev_value on systems where the size of a pointer is bigger than the size of an int. On such systems we'll copy the uninitialized stack bytes from the timer_create() call to userland when the timer actually fires and we're going to deliver the signal. Initialize sigev_value with 0 to plug the stack info leak. Found in the PaX patch, written by the PaX Team. Fixes: 5a9fa7307285 ("posix-timers: kill ->it_sigev_signo and...")

time: Consolidate the time accessor prototypes

2014-07-23T17:17:54+00:00

Right now we have time related prototypes in 3 different header files. Move it to a single timekeeping header file and move the core internal stuff into a core private header. Signed-off-by: Thomas Gleixner Signed-off-by: John Stultz

time/timers: Move all time(r) related files into kernel/time

2014-06-23T09:22:35+00:00

Except for Kconfig.HZ. That needs a separate treatment. Signed-off-by: Thomas Gleixner
