Introduce a SharedLog that can be shared among all Tethering
components. All log entries go to the same log, and each includes
its subsystem name. Additionally, all entries emitted to the
system log shared the same tag, so can easily be watched.
More subsystems can inherit a SharedLog, but to minimize cherry-pick
conflicts we limit ourselves to these changes only.
Test: as follows
- built
- flashed
- booted
- log output observed via dumpsys
- runtest frameworks-net passes

This patch adds a space character between "synchronized" and
"(mTheLockVariable)" so that all synchronized block have a consistent
syntax. Basic stats shows that "synchronized (" is x10 time more likely
than "synchronized(".
This facilitates finding all locked sections by grepping.
Test: no semantics changes
Bug: 37119619
Change-Id: Id860700efa85ffebafed11af3a2997bc115d9c03
This patch introduces between ConnectivityManager and
ConnectivityService a mechanism for propagating back to clients
informative errors in the form of error codes and associated custom
runtime exceptions.
Without error code, the service can only throw a limited number of
different exceptions over Binder. Furthermore the throw site stack
traces are always loss. Although for individual instances of a throw,
the error message can be inspected, aggregations of stack traces from
app crashes sanitize error messages and only leaves the stack traces.
This makes debugging dificult for some service calls such as
requestNetwork that can have a variety of failure modes.
In this patch only one failure mode is codified. More can be added later
at a light cost by: 1) defining an error code, 2) defining an
associated exception, 3) mapping the code to the exception. This patch
can serves as a template for doing so.
Test: $ runtest frameworks-net,
#testNetworkRequestMaximum() detects the new exception type.

Wifi Aware networks are per app - i.e. a requestor gets
a dedicated network. Change verifies that the only the
original requestor matches the created network (using UID).

This patch cleanups conversion of boolean values to ints when reading
configuration values or sending Messages whose arg1 or arg2 has boolean
semantics.

This patch moves reportNetworkConnectivity onto the handler of
ConnectivityService.
This allows:
- to inspect NetworkAgentInfo on the ConnectivityService handler,
which is always more correct than doing so on a Binder thread.
- to improve locking policies around NetworkAgentInfo.

Symptom:
AppOps verified the incorrect package of calling tether state
changing API.
It threw SecurityException by mistake.
Solution:
Pass the correct package name to enforceTetherChangePermission.

This path changes a dangerous lock path in reportNetworkConnectivity().
This methods is called outside of the main ConnectivityService handler
and takes a lock on a specific NetworkAgentInfo whose connectivity
status is being reported.
While this lock is held, reportNetworkConnectivity() goes on and query
the network policy state for that network, which may ends into
NetworkPolicyManagerService.
Instead, the lock on NetworkAgentInfo is only held long enough to make a
copy of LinkProperties, which is then passed to
NetworkPolicyManagerService without that lock.
Bug: 36902662
Test: could not repro b/36902662, reportNetworkConnectivity() works.

This allows an application that knows how to provide seamless
network connectivity (e.g., using QUIC multipath) to find out if
doing so is desired.
