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. Bug: 29054680 Change-Id: Ie7512259150e146d8e382dc64d40e8faaa438917 Signed-off-by: Amit Pundir <amit.pundir@linaro.org>
The android-*.config files in this directory are meant to be used as a base
for an Android kernel config. All devices should have the options in
android-base.config enabled. While not mandatory, the options in
android-recommended.config enable advanced Android features.
Assuming you already have a minimalist defconfig for your device, a possible
way to enable these options would be:
ARCH=<arch> scripts/kconfig/merge_config.sh <path_to>/<device>_defconfig kernel/configs/android-base.config kernel/configs/android-recommended.config
This will generate a .config that can then be used to save a new defconfig or
compile a new kernel with Android features enabled.
Because there is no tool to consistently generate these config fragments,
lets keep them alphabetically sorted instead of random.
