7e689a1828 Handle SPOID calculation for L3
[ Merge of http://go/wvgerrit/101443 ]

The WVDrmPlugin has a single CdmIdentifier. The CdmIdentifier contains
a SPOID that is calculated from the device ID (keybox or OEM cert),
an application reverse domain name and possibly an origin.

The CdmIdentifier is set and SPOID calculated on certain calls into
WVDrmPlugin. Once it is set, it will not be recalculated. We prevent
certain operations such as modifying the origin once the CdmIdentifier
has been set as this will require recalculating the SPOID.
Recalculating the SPOID may affect open sessions or calls in progress.

In a similar way, modifying the security level, will affect the
Device ID value and in turn the SPOID. The security level cannot be modified
if any sessions are open. This does leave open the possibility that the
SPOID may be calculated at one security level, sessions are then closed,
and the security level is then changed without an error being flagged.

The provisioning certificate file name is based on the SPOID. When
the SPOID does not match the security level, either the provisioning
information may not be found even though that security level has
been provisionined or the provisioning information may be stored
in an incorrect location if provisioning occurs.

The correct solution is to prevent modifications to the security level
once the CdmIdentifier is set. This is a behavior change and might
impact apps. We will reevaluate this for the next release.

For now, we will work around this. When the CdmIdentifier is set for L3,
we will calculate SPOIDs with both L1 and L3 device IDs and check if
provisioning previously occurred with SPOIDs calculated for that level.
If so, use that level, otherwise use L3.

bbe9f6afc4 Add ATSC support - part 1
[ Merge of http://go/wvgerrit/100864 and http://go/ag/10704773 ]

ATSC 3.0 allows for licenses to be downloaded OTA and are tied to
a DRM certificate that may be shared across apps. The provisioning
process for ATSC may happen at the factory or during an OS update.

This contrasts from the regular OTT model, which requires that
provisioning and license download have an uplink as well as a
downlink connection.

This adds support for the ATSC mode property. ATSC mode can only be
set (or unset) before sessions are opened. Once the CDM identifier is
set/sealed, requests to modify the ATSC mode will be rejected.

If one needs to open sessions with both ATSC mode and regular (non-ATSC)
mode, separate MediaDrm objects will need to be created. The default
mode is to not use ATSC.

Enable ATSC mode by calling
  mediaDrm.setPropertyString("atscMode", "enable")

Disable ATSC mode by calling
  mediaDrm.setPropertyString("atscMode", "disable")

Provisioning and unprovisioning requests for ATSC will be rejected as
certificates will be retrieved by the ATSC service.

e27bc4ba6a Accept a security level to be specified during provisioning
[ Merge of http://go/wvgerrit/97267 ]

In earlier releases, provisioning would occur based on a cached
security level. If an open session call returned a NotProvisionedException
the security level would be cached for use with any future provisioning
call.

An app would have to set the security level, then call openSession,
have it fail and then request provisioning. This fits the normal flow of
most apps. Still on occasion, an app might change requested security level
after an openSession call failed. Using the cached security level
would result in unexpected behavior.

This change allows provisioning to occur at the last security level that
was set.

9c60d1e1ae Adding app package name to license request.
[ Merge of http://go/wvgerrit/94323 ]

Content providers wish to know the application package name that is
requesting a license from the content server.  The app package name that
is provided to the CDM during initialization is provided to the client
identification message as a key-value pair during license request
generation.  App packages names are keyed under 'application_name'.

This feature was tested manually by scraping the content of the license
request for YouTube TV.

5bd4dbb502 Use license.widevine.com cert for provisioning server

This CL changes the certificate provisioning code to verify the
provisioning message using a cert from license.widevine.com instead of
the staging certificate.

It also adjusts the certificates in config_test_env.cpp because the
license and provisioning servers are different and may probably have
different certs.

ce6bd41627 Define Provisioning-Unique ID for New Device IDs
(This is a merge of wvgerrit/25583)

Devices that use Provisioning 3.0 did not have a Provisioning-Unique ID
defined. Attempting to retrieve it would result in an error.

Devices that use SPOIDs with keyboxes would expose the keybox's real
Provisioning-Unique ID when asked. This is a security flaw.

To solve both cases, an alternative Provisioning-Unique ID is used,
consisting of the Device-Unique ID bitwise-inverted.

c0a7655834 Maxing Out Sessions Can Cause SPOID Failures
(This is a merge of http://go/wvgerrit/25581)

To prevent dead DRM Plugins from being instantiated when there are no
sessions available, the time at which the device ID is queried has been
moved from instantiation-time to SPOID-calculation-time.

SPOIDs can now fail to be generated. Which means anything that depends
on a SPOID may fail because of this. However, this is a more actionable
problem for apps than having them receive a dead or unusable DRM Plugin
object.

19947dfe6f Move SPOID Enable/Disable Logic Out of WVDrmPlugin
(This is a merge of http://go/wvgerrit/25580)

While writing fixes for b/36660726, b/34716264, and b/36065223, it
became clear that having the logic that checks whether the device
supports SPOIDs embedded inside WVDrmPlugin was complicating its code
and inhibiting testing of the class. By moving this check into the code
that instantiates WVDrmPlugin, the result of the calculation can be
independently tested while the tests for WVDrmPlugin can put it in
whatever state they need for the sake of unit testing.

As a consequence of this, the check on retrieving the "deviceUniqueId"
byte array property, which was removed when SPOIDs were implemented, can
be reinstated.

Adds code to the Widevine Glue Layer that drives the generation and use
of SPOIDs on platforms that support SPOIDs. (All devices whose first
release is Android O or later.) Note that this only applies to the new,
Treble-ized API. If the Widevine DRM Plugin is accessed through the old
API, it will not use SPOIDs. This is by design because the old API does
not provide an application package name, so SPOID generation is no
better than the existing, origin-based solution.
