Remove Binder.getOrigCallingUid().
Replaced all remaining places that used it with explicit user
specification.
While doing this, I ran into stuff that was creating PendingIntent
objects (that now need to specify the explicit user they are for),
which are also posting notifications... but have no way to specify
the user for the notification.
So the notification manager in the system process now also gets a
formal concept of a user associated with the notification, which
is passed in to all the necessary aidl calls. I also removed the
old deprecated aidl interface for posting/cancelling notifications,
since we now always need a user supplied.
There is more work that needs to be done here, though. For example
I think we need to be able to specify USER_ALL for a notification that
should be shown to all users (such as low storage or low battery).
Along with that, the PendingIntent creation needs to be tweaked to
be able to handle USER_CURRENT by evaluating the user at the point the
pending intent is sent.
That's for another change, however.

Improve multi-user broadcasts.
You can now use ALL and CURRENT when sending broadcasts, to specify
where the broadcast goes.
Sticky broadcasts are now correctly separated per user, and registered
receivers are filtered based on the requested target user.
New Context APIs for more kinds of sending broadcasts as users.
Updating a bunch of system code that sends broadcasts to explicitly
specify which user the broadcast goes to.
Made a single version of the code for interpreting the requested
target user ID that all entries to activity manager (start activity,
send broadcast, start service) use.

Always-on VPN.
Adds support for always-on VPN profiles, also called "lockdown." When
enabled, LockdownVpnTracker manages the netd firewall to prevent
unencrypted traffic from leaving the device. It creates narrow rules
to only allow traffic to the selected VPN server. When an egress
network becomes available, LockdownVpnTracker will try bringing up
the VPN connection, and will reconnect if disconnected.
ConnectivityService augments any NetworkInfo based on the lockdown
VPN status to help apps wait until the VPN is connected.
This feature requires that VPN profiles use an IP address for both
VPN server and DNS. It also blocks non-default APN access when
enabled. Waits for USER_PRESENT after boot to check KeyStore status.

Handle SCREEN_ON/OFF broadcasts without blocking.
NetworkPolicy currently uses a single background thread to process
various broadcasts. When processing other broadcasts, this thread
can block our handling of SCREEN_ON/OFF, which are sent as ordered
broadcasts.
This change moves SCREEN_ON/OFF handling to the main thread, and
dispatches a one-way message to the background thread, allowing the
ordered broadcast to always proceed.

Combine network subtypes by default.
Subtype controls (3G-vs-4G) aren't exposed in the UI, so tracking

some GSM networks can regularly flap between two subtypes.

Move network stats to FileRotator pattern.
Split existing network stats into two separate classes: a recorder
which generates historical data based on periodic counter snapshots,
and a collection of historical data with persistance logic.
Recorder keeps a pending history in memory until outstanding data
crosses a specific threshold. Persisting is handled through a given
FileRotator. This pattern significantly reduces disk churn and
memory overhead. Separate UID data from UID tag data, enabling a
shorter rotation cycle. Migrate existing stats into new structure.
Remove "xt" stats until iptables hooks are ready. Avoid consuming
Entry values when recording into NetworkStatsHistory. Assign
operation counts to default route interface.
Introduce "Rewriter" interface in FileRotator with methods to enable
rewriteAll(). Introduce IndentingPrintWriter to handle indenting in
dump() methods.

Process AMS events in NetworkPolicy handler.
When a process changes foreground status or dies, NetworkPolicy
updates its internal state with a lock held. In cases where there
is contention, this can block the AMS handler and prevent other
events, such as broadcasts, from being dispatched.
This change moves the incoming AMS events to an existing internal
NetworkPolicy handler thread, where they can execute without

should be established. Better locking around enabled flags.
When data network would be over limit, proactively disable data on
that network. Enable when policy is snoozed or when cycle resets.
Track and dismiss notifications from now-stale policies.

Background data notification, API clean up.
When restricting background data, show ongoing notification to give
easy access to re-enable. Deprecate getBackgroundDataSetting() API
to always return true, since NetworkInfo.isConnected() is new source
of truth. Handle upgrade path by reading from existing secure value,
and kick one last broadcast when changing value. Remove background
data code from ConnectivityService.
Remove warning alerts, since they push ifaces into restricted list;
should only happen when iface has limit.

Foreground/background network stats using sets.
Teach NetworkStats about "counter sets" coming from kernel, and use
them to track usage in foreground/background. Add AID_NET_BW_ACCT to
system_server so it can control counter sets.
Move to composite key of NetworkIdentitySet, UID, set, and tag when
recording historical usage. Persisting still clusters by identity,
since that is heaviest object.
Request async stats poll during systemReady() to bootstrap later
delta calculations. Reset kernel counters when UID removed. Update
various tests.

Network stats with varint, omit parcel fields.
Persist NetworkStatsHistory using variable-length encoding; since
most buckets have small numbers, we can encode them tighter. Initial
test showed 44% space savings. Also persist packet and operation
counters.
Let NetworkStatsHistory consumers request which fields they actually
need to reduce parcel overhead.
Tests for verify varint and history field requests, also verify end-
to-end by persisting history into byte[] and restoring. Expose
bandwidth control enabled state. Extend random generation to create
packet and operation counts. Moved operation counts to long.
Fix bug that miscalculated bytes since last persist, which would
cause partial stats loss when battery pulled.

UID network stats, secure settings, and random.
Collect UID-granularity network stats during regular poll event. Add
dumpsys argument to generate fake historical data for debugging, and
move stats parameters to Settings.Secure.

Map network identity using ConnectivityService.
Instead of deriving network identity based on raw subsystem broadcasts,
listen for updates from ConnectivityService. Added atomic view of all
active NetworkState, and build map from "iface" to NetworkIdentity set
for stats tracking.
To avoid exposing internal complexity, INetworkStatsService calls use
general templates. Added TelephonyManager mapping to classify network
types using broad labels like "3G" or "4G", used to drive templates.
Cleaned up Objects and Preconditions.

Collect historical network stats.
Periodically records delta network traffic into historical buckets to
support other services, such NetworkPolicyManager and Settings UI.
Introduces NetworkStatsHistory structure which contains sparse, uniform
buckets of data usage defined by timestamps. Service periodically
polls NetworkStats and records changes into buckets. It only persists
to disk when substantial changes have occured. Current parameters
create 4 buckets each day, and persist for 90 days, resulting in about
8kB of data per network.
Only records stats for "well known" network interfaces that have been
claimed by Telephony or Wi-Fi subsystems. Historical stats are also
keyed off identity (such as IMSI) to support SIM swapping.

Tests for NetworkPolicyManager rule generation.
Verifies that policy changes trigger rule updates that respect current
foregroundActivities status. Also verifies logic that promotes a UID
based on its most-foreground PID. Verifies that policy changes result
in immediate rule changes.
Also verifies that BACKGROUND_DATA_SETTING_CHANGED broadcasts are sent
by policy changes.

Teach NetworkPolicyManager how to dumpsys itself.
Includes details on all internally known UIDs, which can be used for
debugging purposes.

Policy and rules work for ConnectivityManager.
Teach ConnectivityManager about UID-specific rules derived from policy,
such as rejecting network traffic on "paid" interfaces. Calls that
return NetworkInfo now filter based on any REJECT rules in effect for
the calling UID. (Added uid parameter if callers that still want all
interfaces.)
Changed NetworkPolicyManager to derive rules based on current policy
combined with PowerManager and ActivityManager status, which it passes
to ConnectivityService for eventual enforcement through netd. When
rules change the usability of a NetworkInfo for a specific UID, it also
dispatches CONNECTIVITY_ACTION broadcasts to that UID. Combined paid
and background policy together to match current working definition.

Observe screen on/off events in NetworkPolicy.
The POLICY_REJECT_BACKGROUND policy requires that network traffic be
blocked when a UID goes into the background. Even if the UID has an
activity in the foreground, it's considered "background" if the screen
is turned off.
This changes watches for SCREEN_ON/OFF broadcasts, and rule generation
now observes screen state. It also introduces an observer pattern so
that ActivityManager doesn't directly know about NetworkPolicy, and
moves the service management into SystemServer.

APIs to profile network usage for current UID.
Added startDataProfiling() and stopDataProfiling() to TrafficStats,
which can be used by apps to measure network usage delta between two
points in time. Currently takes two NetworkStats snapshots and returns
delta, which will eventually include tag-level granularity. Added
tests for NetworkStats delta subtraction.
Added NMS.getNetworkStatsUidDetail() that returns stats for specific
UID. Always gives stats access for the calling UID, otherwise enforces
that caller has permission. Fix readSingleLongFromFile(), since
/proc/ files don't have well-defined lengths.

First pass at NetworkPolicy and activity tracking.
New system service that maintains low-level network policy rules and
collects statistics to drive those rules. Will eventually connect to
netfilter kernel module through NetworkManagementService and "netd".
Begin tracking foreground activities in ActivityManagerService, which
is updated as part of OOM adjustment. Eventually a network policy of
POLICY_REJECT_BACKGROUND will reject network traffic from background
processes.
