* android: fiq_debugger: restrict access to critical commands.Mark Salyzyn2017-05-101-0/+1
| | | | | | | | | | | | | | | | | | Sysrq must be enabled via /proc/sys/kernel/sysrq as a security measure to enable various critical fiq debugger commands that either leak information or can be used as a system attack. Default disabled, this will leave the reboot, reset, irqs, sleep, nosleep, console and ps commands. Reboot and reset commands will be restricted from taking any parameters. We will also switch to showing the limited command set in this mode.
