Subject: ANDROID: restrict access to perf events
|
|
|
|
Add:
|
|
CONFIG_SECURITY_PERF_EVENTS_RESTRICT=y
|
|
|
|
to android-base.cfg
|
|
|
|
The kernel.perf_event_paranoid sysctl is set to 3 by default.
|
|
No unprivileged use of the perf_event_open syscall will be
|
|
permitted unless it is changed.
|
