Avoid get same timestamps in log testcase

2019-07-08T17:03:40+00:00

for arm64, userspace get time by vDSO, no syscall overhead.
multiple_test_2 sometimes get 2 same timestamps now, then testcase
fails.

introduce auditctl and use it to configure SELinux throttling

2019-04-10T03:54:47+00:00

In an effort to ensure that our development community does not
introduce new code without corresponding SELinux changes, Android
closely monitors the number of SELinux denials which occur during
boot. This monitoring occurs both in treehugger, as well as various
dashboards. If SELinux denials are dropped during early boot, this
could result in non-determinism for the various SELinux treehugger
tests.

Introduce /system/bin/auditctl. This tool, model after
https://linux.die.net/man/8/auditctl , allows for configuring the
throttling rate for the kernel auditing system.

Remove any throttling from early boot. This will hopefully reduce
treehugger flakiness by making denial generation more predictible
during early boot.

Reapply the throttling at boot complete, to avoid denial of service
attacks against the auditing subsystem.

Delete pre-existing unittests for logd / SELinux integration. It's
intended that all throttling decisions be made in the kernel, and
shouldn't be a concern of logd.

Bug: 118815957
Test: Perform an operation which generates lots of SELinux denials,
      and count how many occur before and after the time period.

Read selinux_denial_metadata from /vendor

2019-01-23T17:58:37+00:00

selinux_denial_metadata contains device-specific information, so it is
being moved to /vendor.

Bug: 5159394
Test: bug information is still preserved in avc logs, e.g.
