92a946d09f Add getDefaultNetwork to the NetworkStats public API.
This allows an app using the public API to know whether the
traffic in a particular bucket was on the default network
(i.e., the network was selected by the system), or not (i.e.,
the network was selected by the app).

0fff56eae5 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.

3e85855083 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.

IpSecTunnelInterface to the IpSecManager surface.
This object will be used to control IPsec tunnels.

-Add methods to create and use an IpSecTunnelInterface
-Update the IpSecTransform builder to create Tunnel

0d483b76f3 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.

3167625a15 Prevent Closure of Underlying Socket FDs
The version of applyTransportModeTransform() and
removeTransportModeTransform() that accepted
Socket and DatagramSocket were closing the underlying
FDs upon return. It's unclear whether this is due to
a behavior change elsewhere in ParcelFileDescriptor,
but either way, converting to using getFileDescriptor$
and then calling dup() explicitly rather than relying
on ParcelFileDescriptor seems like a better idea anyway.

5a19b9500d 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

5e8544685d IpSec Invalidate the Resource IDs on close()

the resource IDs of all objects when we close() them.

aa7ba31c8e Use NetworkStatsService to get stats for apps
Move the native implementation of TrafficStats to NetworkStatsService
and apps need to get the NetworkStatsService binder interface from
system_server in order to get the network usage stats since boot. This
implementation can hide the detail of retrieving network traffic
information from apps and the NetworkStatsService can choose which
methoed it use to get the data depending on the kernel version of the
device.

20e96c55d5 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.

eb1d489332 Validate IpSecAlgorithm Length
Improve the Validation of IpSecAlgorithm by
explicitly checking the length in addition to
the truncation length (previously an oversight).
In addition, we now check the lengths during
un-parceling, which will catch someone maliciously
manually building a parcel and passing it, bypassing
the checks in the constructor.

2a30daf3f7 Fix signature for finalize() to resolve API Lint error
The API linter on goog/master noticed that this method is

change is probably related to a signature change from the
internal finalize method which throws a Throwable. Fix the
method in IpSecManager to throw Throwable, which should
fix the current.txt and resolve the lint error.

7c19a1abd6 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.

All of the input to IpSecService over the Binder
interface needs to be validated both for sanity
and for safety.

-Sanity check all the parameters coming from binder.
-Added setters for IpSecConfig to decouple the test
 from the IpSecManager. This was needed because the
 input validation caused the tests to fail due to a
 null parameter that was previously un-tested.
-Added the mode flag to the IpSecConfig bundle this
 oversight was found during testing.
-Expose the getResourceId() methods for testing in
 UdpEncapsulationSocket, SecurityParameterIndex, and
 IpSecTransform classes.
-Remove the unneeded getIpSecConfig() from
 IpSecTransform: unneeded now that we can synthesize
 configs.
