Summary [Mac][iOS][WK2] Whitelist sysctl-read
Brent Fulgham
Reported 2017-03-07 14:20:25 PST
We only have a small number of cases where we use sysctl in WebKit, and those cases are always in a read-only mode. Modify our sandboxes to limit 'sysctl' use to read-only, and whitelist that access for the very small number of cases we actually use: CTL_KERN, KERN_PROC. KERN_PROC_PID, # CTL_HW, HW_AVAILCPU CTL_HW, HW_NCPU hw.model kern.memorystatus_level
