collect statistics.
Test: make. Simulate watchdog and check events in logcat.

Change captureAudioOutputAllowed to check client pid.
Check calling uid with AID_AUDIOSERVER instead of calling pid with
own pid. This is consistent, and works if AudioFlinger and
AudioPolicyManager exist as different processes.
Remove getpid_cached since getpid() is very fast. This removes
any initialization issues.
Replace getuid() with AID_AUDIOSERVER to remove ambiguity of
multiple native audio services for multiple users. Only
one exists regardless of users.
Do not use multiuser UID checks for certain native services
that do not spawn for multiple users to prevent accidently exposure.
Move permission checks to use ServiceUtilities for control and
consistency.
Rename isTrustedCallingUid to isAudioServerOrMediaServerUid
so that permission check is explicitly known to caller.
Update MediaLogService to use ServiceUtilities.
Test: Basic sanity

When a transaction to IAudioFlinger or IAudioPolicyService is detected
from an unauthorized source, return the INVALID_OPERATION status in
reply Parcel and not as transaction status.
Also removed check on SET_RINGER_MODE as it is not implemented on client
side and allow SET_MODE from system AIDs instead of just audioserver.

Only allow setParameters() for reserved keys when received from
audioserver UID. For instance, keys used to control routing or audio
stream configuration are reserved for use by audio policy manager.
Also use multiuser_get_app_id() instead of duplicated code to
extract application ID from UID.

Fix UID checks in audioserver to take into account multi user UIDs
where the top part above AID_USER_OFFSET contains the user number.

Add a mechanism to monitor execution time of incoming binder
calls to audio flinger and audio policy and cause native audioserver
restart in case of timeout.

Block incoming binder calls to audio flinger and audio policy service
for sensitive functions if they are not coming from a system UID.

Add MicrophoneInfo class in native side and native logic for supporting
query all available microphones.
Bug: 64038649
Test: Run test and check the print log.
Change-Id: Ic0a9cce55a1265a66ba08fe81b56b56cb88ba42f
To protect user's privacy if a UID is in an idle state we allow
recording but report silence (all zeros in the byte array) and once
the process goes in an active state we report the real mic data.
This avoids the race between the app being notified aboout its
lifecycle and the audio system being notified about the state
of a UID.
Test: Added - AudioRecordTest#testRecordNoDataForIdleUids
Passing - cts-tradefed run cts-dev -m CtsMediaTestCases
-t android.media.cts.AudioRecordTest

Refactor the mechanism used by audio record tracks to query and
attach to an input mixer/stream in audio flinger. This will:
- reduce the number of binder transactions needed to create a record track
- move sample rate, framecount and flags validations to audio server side
- move audio session allocation to audio server side
- prepare restriction of certain binder transactions to audioserver only
Also:
- renamed openRecord() to createRecord() for consistency with AudioTrack
- make AudioRecord mStatus update consistent when calling default
contructor + set() or constructor with arguments
- make AudioClient, CreateTrackXXX and CreateRecordXXX classes derive
from Parcelable
- restore audio session ID validity check in AudioFlinger::createTrack()
Test: CTS tests: AudioRecordTest, AudioRecordingConfigurationTest, AudioPreProcessingTest
Test: manual test for capture use cases: camcorder, OK Google, VoIP calls

Use AIDL to generate the IAudioRecord interface rather than using
a manually implemented interface.

Make the binder opcode names match the method names
Test: builds OK, this does not change behavior
Change-Id: I7c56ddd1efabc81b5d0ab2d1979ba1001ec76994
This will allow to track activity at the track level instead of
at audio session level as only possible with current implementation.
AudioTracks and AudioRecords will receive a unique audio port ID the
first time they register to audio policy with
getOutputForAttr()/getInputForAttr() and keep this ID for their
lifetime.
This CL is the first partial change and just updates the
audio policy and audio flinger APIs used at track creation time.
Test: basic regression test of audio playback and capture use cases
Change-Id: I8d612e67738e120494f61e3f7c60bfd0b2c6a329
This makes it so audioserver doesn't need to link against the entire libmedia,
which has dependencies on camera, ICU, OpenGL and other things that aren't
needed for audio.
Test: build/boot
