bb31e20bcd Add checks to ensure SPIs are not reused
This change adds an additional check in CheckIpsecConfig to prevent
users from using the same SPI twice. This allows for a more granular
error message.

01e9f19d7b Rename create/delete transform methods
CreateTransportModeTransform and DeleteTransportModeTransform are both
agnostic as far as which mode of transform it creates/deletes. As such,
to facilitate the implementation of tunnel mode, this patch renames them
to CreateTransform and DeleteTransform, along with all test names.

cd969ef97c Add the default network to NetworkStats and NetworkStatsCollection.
This allows us to maintain NetworkStats entries that track
whether the traffic was on the default network.

At the moment, the stats collection code always passes in
DEFAULT_NETWORK_NO. However, this value is a no-op, since it is
not persisted to disk. Only the ident, the uid/set/tag, and the
packet/byte/operation counters are persisted.

A future change will add defaultNetwork to the ident and start
persisting it.

dd2ed2bbe7 IpSec - API Tweak for removeTransportModeTransform
Because IpSecTransforms are now unidirectional,
and because the only mechanism for removing Transforms
removes it from both directions, the API can no longer
use the Transform parameter to meaningfully validate
that the caller had applied a transform. Since that
functionality was as-yet unimplemented and is now
infeasible, the transform parameter is removed.

3865a008e7 Make Transforms Unidirectional
Convert the IpSecTransform from being a bi-directional
pair of SAs to a unidirectional single SA. This CL
also removes the concept of "direction from SAs meaning
that a IpSecTransform may now be applied to a socket
in either direction.

-Make transforms unidirectional
-Add Convert allocateSpi() to use destination rather
 than direction and remote address
-Remove directionality from builders for IpSecTransform
-Change applyTransportModeTransform() to take a
 direction in which to apply the transform object.
-Additional minor naming updates
-Restrict IpSecConfig to only print keys on eng builds
-Move DIRECTION constants to IpSecManager
-Add sourceAddress parameter to IpSecTransform to provide
 additional guarantees about the source address of data;
 (explicit failure rather than implicit failure).
-Move SPI to the build() method of IpSecTransform

d21105064e Convert IpSecService resources to use refcounting
This is part 2 of 2 of the refcounting refactor for IpSecService
resources.

Switched ManagedResources to use RefcountedResource structure for
managing reference counts and eventual cleanup. Further, resource arrays
and quota management have been aggregated into a UserRecord for better
isolation. UID access checking has been similarly moved into the
UserRecordTracker, and resourceId checking has been rolled into
RefcountedResourceArray's accessor methods.

11c8f27e22 Add reference counted resources to IpSecService
This patch adds (but does not enable the usage of) RefcountedResource
objects to IpSecService, with tests to ensure correct function. This is
patch 1 of a series of patches to refactor the resource management
systems in IpSecService.

RefcountedResource objects allow for management of acyclical dependency
trees, ensuring eventual cleanup when resources are no longer used. This
cleanup may be triggered by binder death or by explicit user action.

fbe3a82340 Use consistent naming for allocating SPI.
Throughout the IPsec code (API, system server, netd) we use "reserve"
SPI and "allocate" SPI interchangeably. This renames to use "allocate"
everywhere for self-consistency and consistency with the kernel
(ALLOCSPI).

In javadoc, I am leaving the word "reserve" in several places because it
is still an accurate description of how the method behaves.

Hugo Benichi
f123c85f29 DefaultNetworkEvent metrics: rehaul
This patch changes instrumentation of default networks and default
network events:
- stop logging events for default network transitions,
  but instead consistently log one event per continuous segment
  when one given network was the default, including logging an
  event for when there is no default network.
- keep a separate rolling buffer of DefaultNetworkEvent for
  dumpsys and bug reports.

These changes allow to simplify post aggregation of default network
event metrics by removing any need to do time series processing.
Instead, metrics and counters can be implemented withouth any ambiguity
by following the recipe:

% of x = sum(duration | x = true) / sum (all durations)

where x can be various conditions such as:
- the default network was validated
- the default network was WiFi
- the default network was IPv6
- there was no default network
- ...

Most importantly, this new logging scheme allows to measure much more
reliably:
- the % of the time that a device had Internet, in the sense that the
default network was validated.
- the time transitions between default networks, keyed by previous and
new transports/link layer, which allows to derive wakelock durations
and wakelock power costs from default network switches.

This patch also simplifies the dumpsys interface of the connmetrics
service and reduces the commands to three:
- "flush" for metrics upload.
- "proto" for printing buffered event in text proto format.
- "list" for listing all events and statistics.

07e19362de Define NOT_ROAMING network capability.
The "roaming" state of a network really belongs on NetworkCapabilities
instead of being published through NetworkInfo.isRoaming().  One major
reason is to support developers creating NetworkRequests for a
non-roaming network.

Watch for any capability changes that network statistics are
interested in (either metered or roaming) and notify it to perform
an update pass; fixes bug where we previously only triggered on
roaming changes.

Fix bug in VPNs where metered/roaming capabilities of underlying
networks weren't being propagated; this was probably preventing
some jobs from running over unmetered networks, and causing other
jobs to run over roaming networks!  Also passes along link bandwidth
information from underlying networks, and propegates any changes
to underlying networks.

Fix race condition by reading prevNc inside lock.  Utility methods
correctly calculate min/max link bandwidth values.

cd8d58c405 Extract logging of default network events
This patch extracts the logging of DefaultNetworkEvent from inside
ConnectivityService and move it to a new DefaultNetworkMetrics class.

The DefaultNetworkMetrics is a singleton owned by the
IpConnectivityMetrics singleton implementing the metrics service for
core networking. ConnectivityService has access to this singleton via
LocalServices.

This class layout will allow to remove the Parcelable interface of
DefaultNetworkEvent and will instead let the IpConnectivityMetrics
service grab metrics from the DefaultNetworkMetrics directly.
