Callbacks
- DataUsageCallback renamed to UsageCallback
- DataUsagePolicy removed; passing in params directly to register method
- making it an abstract class
- passing in (networkType, subscriberId) that reached its threshold
- renaming onLimitReached to onThresholdReached to match existing naming
- only monitor single network,subscriberId
- no monitoring of specific uids; using device or user wide instead
Tags
- only owner uid can read its tags
- exposing only TAG_NONE to match service side

Fixed connectivity state in some restricted network scenarios.

NetworkPolicyManagerService (NMPS) keeps an internal list of uid
rules (mUidRules) for network restrictions, and when these rules
changes it needs to notify external listeners (such as
ConnectivityService / CS).
Prior to Android N, both Data Saver mode (the feature previously known
as "Restrict Baground Data") and Battery Save mode used the same set of
firewall rules to implement their restrictions: when Battery Saver mode
NPMS would mark all networks as metered and set the proper firewall
rules externally.
Recently, these 2 modes were split in 2 distinct firewall rules and
NMPS.updateRuleForRestrictBackgroundLocked() was changed to update
the mUidRules logic based on the Data Saver firewall (since the Battery
Saver firewall changes are handled externally, on
updateRuleForRestrictPowerLocked()). As such, CS was not notified when
the power-related changes were made, which would cause apps to get a
state of CONNECTED / CONNECTED when querying its active connection.
Another scenario that is not properly handled is when a UID whitelisted
for Data Saver is brought back to foreground: although the proper
firewall rules are set, CS is not notified, and the apps state would be
DISCONNECTED / BLOCKED.
This CL introduces many changes that fix this issue:
- Fixed updateRuleForRestrictBackgroundLocked() to invoke
onUidRulesChanged() when the Battery Saver status changed.
- Fixed updateRuleForRestrictBackgroundLocked() to invoke
onUidRulesChanged() when an app whitelisted for Data Saver is brought
back to the foreground.
- Added a new API (onRestrictPowerChanged() and getRestrictPower())
to notify external services about Battery Saver mode changes.
- Fixed CS logic to properly handle the Battery Saver changes.
Externally to this change, the CTS tests were also improved to verify
the apps get the proper connection state; they can be verified running:
cts-tradefed run commandAndExit cts -m CtsHostsideNetworkTests \
-t com.android.cts.net.HostsideRestrictBackgroundNetworkTests

This change refactores the mUidRules to use bitmasks, in preparation for
another change that will fix the issue.
It also fixes a minor bug that was preventing removed packages to be
removed from the whitelist.

- Set the new VPN network as CONNECTING initially to avoid spamming
apps with useless notifications ahead of the network being fully

Fix: 28335277

Network creation setup sometimes involves extra steps after actually
calling into netd to create the underlying network, rules & routes &
to begin allowing sockets bound to it.
For example, VPN networks can set a UID whitelist or blacklist. This
should happen:
- AFTER there is a netID & network created in netd as
network-specific rules will need to be tied to / point at it. Those
rules are tied to the lifecycle of netd's network which is tracked
by `NetworkAgentInfo.created` on the frameworks side.
- BEFORE the CONNECTED broadcast and network callbacks have been sent
out so that we don't create a race condition between clients that
want to use the network and the server actually having the network
ready
The race condition existed prior to this change and required any client
making use of network callbacks to sleep for a short amount of time after
receiving to actually be able to use the network.
Among other things, that race condition is now fixed.

Change-Id: I908d725a84e9590d0da38a586b066a63473d4f28
When a job will eventually run in the foreground, the internal
scheduling needs to ignore any background network restrictions when
satisfying constraints. This also means the job should ignore the
current device doze state, since the requesting app could get the
same behavior by starting their own foreground service.
Always dispatch network policy changes to ConnectivityService first
to ensure that it has up-to-date information. Fix bugs around data
saver that were causing networks to not be marked as BLOCKED for
background apps; before this fix apps would have been spinning in
internal connectivity loops, thinking that the network was actually
connected when the kernel was actually blocking their traffic.
Offer new ConnectivityService method overloads to ignore the blocked
state for a specific UID.
Print unsatisfied job constraints to aid debugging.

Moved several USER_STOPPING registered receivers to listen
to USER_STOPPED, since they don't need to be blocking the
shutdown of the user.
Clear all stale broadcasts when stopping a user, so that we
don't unnecessarily start up processes and deliver stale
broadcasts. This was causing code to run when the user was
already stopped and resulted in crashes when other providers
and services couldn't be started anymore. Hopefully this fixes
many of those races.
