[PATCH] Range checking in do_proc_dointvec_(userhz_)jiffies_conv
When (integer) sysctl values are in either seconds or centiseconds, but
represented internally as jiffies, the allowable value range is decreased.
This patch adds range checks to the conversion routines.
For values in seconds: maximum LONG_MAX / HZ.
For values in centiseconds: maximum (LONG_MAX / HZ) * USER_HZ.
(BTW, does anyone else feel that an interface in seconds should not be
accepting negative values?)
