I'm leaving for vacation for the next two weeks (although I will occasionally check email), so I wanted to resend this so it didn't get missed. In reviewing the alarmtimer code, I ran across a few bugs that should be fixed for 3.1 and backported to 3.0-stable. These are also available in the git repository at: git://git.linaro.org/people/jstultz/linux.git fortglx/3.1/tip/timers/alarmtimers The last of these is a pretty terrible hack, but I've got a more invasive fix (along with other cleanups) queued on top of these for 3.2 that should resolve it. Feel free to take a peek at those changes here: git://git.linaro.org/people/jstultz/linux.git fortglx/3.2/tip/timers/alarmtimers Let me know if you have any thoughts or feedback! thanks -john John Stultz (3): alarmtimers: Avoid possible null pointer traversal alarmtimers: Memset itimerspec passed into alarm_timer_get alarmtimers: Avoid possible denial of service with high freq periodic timers kernel/time/alarmtimer.c | 18 +++++++++++++----- 1 files changed, 13 insertions(+), 5 deletions(-)
