[PATCH 0/2] [SRU] [xenial/linux] CVE-2017-5967

[Tim Gardner]

[Impact]
The time subsystem in the Linux kernel through 4.9.9, when CONFIG_TIMER_STATS is
enabled, allows local users to discover real PID values (as distinguished from
PID values inside a PID namespace) by reading the /proc/timer_list file, related
to the print_timer function in kernel/time/timer_list.c and the
__timer_stats_timer_set_start_info function in kernel/time/timer.c.

[Test Plan]
Boot tested and checked that /proc/timer_stats is gone

[Where problems could occur] 
This does change the kernel ABI interface in that /proc/timer_stats no longer exists.
