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.

Due to multi-branch automerging issue, TRANSPORT_NAMES got inserted
twice into NetworkCapabilities both by commits 45670bb37d and
21665ac809. This patch deletes one of the copy.
Test: no functionality change. Build is fixed.

Update docs based on what new lint detector found. Add new @IntDef
to parameters or methods returning constants or flags, and add
@RequiresPermission to methods mentioning permissions.

If anything unrestricted is bundled in the whole thing has to be
unrestricted (we can't restrict based on destination or intent)
but the NOT_METERED flag wasn't taken into account.
This wasn't a problem before because telephony set that statically
and late, but a change caused it to be marked NOT_METERED earlier
which exposed this bug.

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 patch changes how callback unregistration works in order to be
consistent with undocumented use cases currently de-facto supported
by the API (although in a buggy way):
- callback recycling: releasing then reregistering a callback again.
- multiple request registrations with the same callback.
The second use case is not desirable but needs to be taken into account
for now for the purpose of correctly releasing NetworkRequests
registered in ConnectivityService.
In order to support request release in both use cases with minimal
amount of complexity for the time being the following changes are done:
- request to callback unmapping is done synchronously at callback
release time.
- all requests associated to a callback are unmapped at callback
release time.
This fixes the following issues:
- a callback stops being triggered as soon as it is released.
Otherwise when recycling the callback immediately, it is possible
the previous request associated with it triggers it, confusing the
app.
- when a callback is registered multiple times, the requests are not
leaked.
- when a callback is registered multiple times and then released, the
N-1 first registrations do not trigger the callback anymore.
In the future it would be desirable to enforce the intended 1:1 mapping
between callbacks and requests at registration time.
Bug: 35921499, 35955593, 20701525
Test: - added new tests in ConnectivityManagerTest to test releasing,
recycling, and a disabled test for no multiple regristration.
- new tests catch regression causing b/35921499, b/35955593.

This patch also
- partially reverts commit 7f818778a8
that exposed a getTransports method on NetworkCapabilities.
- moves enumerateBits to BitUtils (as unpackBits), and adds the
reverse packBit method.

This groups them together with the rest of the networking unit
tests. It also speeds up compile/test cycles ("runtest -x" of one
file goes from 1m15s to 30s).

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.

Bug: 3490169
Change-Id: Ibf51049ba8901ae5ca4ea86e2f500944a4738b5c
This patch adds translation from ConnectivityMetricsEvent to
IpConnectivityEvent of recently added fields:
- top-level network id
- top-level ifname
- transports
Also adds inference of link layer from transports or ifname.
At the moment these new fields are not populated in
ConnectivityMetricsEvent. Follow-up patches will fill this gap for
the events of the android.net.metrics package.
Test: new unit tests, $ runtest frameworks-net passes
