If the same app/origin generates multiple provisioning 4.0
requests it is possible that a mismatch between the OEM/DRM
certificate and the wrapped OEM/DRM private key occurs. The CDM
would use the OEM/DRM certificate of the first response one
received, and the wrapped private key of the last request generated.
To avoid this issue, the public key from the most recent request
is cached and checked against the responses received. If the
keys match, that response is accepted; if the keys don't match
than the response is assumed "stale" and the response is dropped.
In an attempt to maintain existing behavior of the CDM, "stale"
responses will return NO_ERROR to the app.
Note: This was tested using both RSA and ECC cert key types.
VIC-specific: Needed to add implementation of StringContains() and
StringEndsWith().

To enable the CDM to determine between OEM vs DRM responses,
a state variable was needed in CertificateProvisioning.
Previously, the presence/absence of the OEM certificate in the
file system was used; however, if two apps (or single app with
multiple origins) attempts provisioning simultaneously, the
later response would trigger unexpected failures.
The main functional changes this provides is that a more informative
error will be returned to the app if they provide a provisioning
response without ever creating a provisioning request; and that
if multiple clients attempted first-stage provisioning simultaneously,
fewer errors will occur.

The CDM API RemoveOfflineLicense() is used to remove an offline
license by key set ID. From the app's perspective, removing the
offline license should not depend on an app to be provisioned, or
the license being loadable. However, internally, the CDM attempts
to restore the license to lock out its usage entry.
An issue arises when the license is not able to be restored, which
will cause errors related to the restoration to be returned to the
app. The license is still deleted in case of errors, but certain
partners have experienced GTS failures when using the MediaDRM API
removeOfflineLicense().
This change attempts to catch some of the common errors, but not all.
If certain errors are encountered during the restoration process, the
are not returned to the app.
Additional error cases may be added later, depending on vendor
feedback.

When CdmResponseType (enum) was transformed to CdmResponseType
(struct), the test printers where not updated to print the result
of failed comparisons. In addition, several logs statements were
updated haphazardly, leaving inconsistencies and potential
compiler-specific behavior.
This CL replaces CdmResponseType std::string operator with a ToString()
method. This is to make it consistent with Google's C++ style guide
on conversion operators vs methods. The string conversion function is
now defined in wv_cdm_types.cpp instead of inline in the header file.
The PrintTo function has been implemented along with the other CDM

CdmEngine will resume normal operation. Engines created after a
device is provisioned will immediately enter normal operations.

reason and are still running. Those apps will need to restart before

The CDM is responsible for telling OEMCrypto the underlying DRM
private key type when loading it into a session. To do this, the
CDM must determine and store the key type of a successfully loaded

This change introduces a class to contain the wrapped key and

In v16, OEMCrypto specifications required that an error be returned if
multiple attempts are made to load an offline license into a session.
This caused the GTS test testConcurrentDrmCertificates to fail. It was
introduced to verify that a license could retrieved and loaded into a
session and then restored. This was based on an app use case.
Ideally we would like to disallow a this behavior but need to make sure
it is not being used by apps.
For now this will be allowed. If detected, the CDM will reintialize the
OEMCrypto session and allow the license to be restored.

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.

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

When the CE CDM 3.5 behavior around service certificates was originally
implemented, it allowed sessions to be created if a service certificate
had not yet been installed, in keeping with the EME spec. However, the
service certificate in use at session creation time was cached, and so
there was a bug where any sessions open before a service certificate was
installed would never be updated with any future service certificates.
The code also caused problems for Android. When it was merged to master,
it was fixed to simply not allow session creation on CE CDM without a
service certificate. However, this created an impedance mismatch between
the CE CDM and EME that has caused pain for Shaka Player Embedded,
Chrome, Chromecast, Fuchsia, and likely every partner that is trying to
implement a fully-compliant EME stack on top of CE CDM.
Removing the code that blocks session creation without a service
certificate is easy. Fixing the bug that motivated it is not. Removing
the caching is not possible because Android needs it for certain
behavior on its end. So instead, the CE CDM will have to iterate over
all open sessions and update their service certificates if the installed
service certificate changes.

As part of implementing this request, CdmSession::DeleteLicense() was
renamed to reflect that it only deletes the *files* associated with a
license, and a new CdmSession::DeleteLicense() has been written that
also cleans up other related data.

Devices with baked-in DRM certs cannot be reprovisioned. As such, we
must protect them against being unprovisioned. Currently, our unit
tests break such devices by attempting to unprovision them. This patch
adds code to block the Unprovision() call on these devices.

RemoveKeys now resets associated crypto and policy resources,
rather than just closing the crypto session. This results in a
MediaCodec.CryptoException with error code ERROR_NO_KEY
rather than ERROR_SESSION_NOT_OPENED, if decrypt is called
afterwards.
Error SESSION_NOT_FOUND_FOR_DECRYPT is made unique. Error codes
were also synchonized between various branches in the widevine repo.
