Now stores tags other than TAG_NONE (0x0), which are useful for app
debugging. Combine UID and tag together into single long key, and
expose tag data through AIDL when requested. Change NMS to track
TAG_NONE as total UID traffic, matching the kernel definition.
Added TAG_MAX_HISTORY to control how long tag-granularity statistics
are stored; overall UID usage is still kept for UID_MAX_HISTORY. Fix
bug to trim NetworkStatsHistory outside normal polling loops to catch
non-active networks and UIDs.
Test to verify UID and tag packing, and to verify that UID traffic on
two networks are combined to match MOBILE_ALL template.

When UID_REMOVED, clean up any existing UID network policy so it
doesn't linger for future apps. Also move any NetworkStatsHistory
to special UID_REMOVED tracking bucket.
Tests for new removal code. Also test detailed UID stats, including
network changes to verify template matching logic.

Teach NMS to read qtaguid stats from kernel, but fall back to older
stats when kernel doesn't support. Add "tags" to NetworkStats entries
to support qtaguid. To work around double-reporting bug, subtract
tagged stats from TAG_NONE entry.
Flesh out stronger NetworkTemplate. All NetworkStatsService requests
now require a template, and moved matching logic into template.
Record UID stats keyed on complete NetworkIdentitySet definition,
similar to how interface stats are stored. Since previous UID stats
didn't have iface breakdown, discard during file format upgrade.

Currently, kernel definition of metered networks is applied at the
interface level. This change maintain list of those metered ifaces
and notifies policy listeners, like ConnectivityService. (This gives
us a consistent picture of when a network would be blocked.)

Watch for network statistics to cross NetworkPolicy warning or limit,
and show notifications to user as needed. Currently checks during
any statistics update, but will eventually move to event registration
through netd when kernel supports.
Fixed accounting bug in getSummaryForNetwork(). Only apply UID policy
to applications; applying to system processes could break critical
services like RIL.

Devices with always present wired ethernet interfaces (as opposed
to usb ethernet dongles) don't have the interface added and removed.
Instead, it is present already at boot time. Change EthernetDataTracker
to support the already existing at boot time case.

The improved keystore will allow clients (Email not the least of them)
to establish SSL connections using custom client certificates. In order
to do this properly, the socket factories they use to establish these
connections need to be able to customize their behavior.

Instead of embedding complex template coexistence rules into policy
service, rely on external editors to enforce, and offer atomic
get/set operations for full policy sets.
Generate default mobile policy when none exists, using default of 4GB
warning and cycle reset of current day. Dispatch listener events
through Handler when holding internal lock, and catch CLASS_UNKNOWN
networks in 3G_LOWER template.

NetworkStats now grows in place with arraycopy() instead of callers
needing to know record count a priori. Better growth calculation for
both NetworkStats and NetworkStatsHistory; 50% each time. Better
estimates of buckets needed in calling services.

Moved so they can be used by both system service and Settings UI, since
they both work with data usage cycles. Still covered by tests.

Define NetworkPolicy as cycle-reset day and warning/limit values, and
set/get through NetworkPolicyManager. Watch ConnectivityManager for
network connection events, and apply quota rules based on matching
interfaces. Policy service matches based on strong identity to support
IMSI-specific policy values.
Calculates remaining quota based on current stats recorded since the
last reset cycle day. Tests to verify edge cases around February.
Persist network and UID policies in XML, and restore on boot.

Implements read/write of network stats using AtomicFile, along with
magic number and versioning. Stores in "/data/system/netstats.bin"
for now. Tests to verify that stats are persisted across a simulated
reboot, and to verify that TEMPLATE_WIFI is working.
Fixed bug where kernel counters rolling backwards would cause negative
stats to be recorded; now we clamp deltas at 0.

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.

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.

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.
Change-Id: I4fd0dad9e1dbccee2c5968244bb1814e6cb2c6e1
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.
