"client_version" is an optional, information field in the protocol for
license requests. It was requested that the CE CDM includes this
information in the license request. It does not hurt to include this
information in the Android license requests too.
If, for some reason, the client cannot provide this information, the
request is still sent out as normal. No reason to prevent an otherwise
valid license request due to a missing optional field.
Note: This field is directly in the LicenseRequest message and not the
ClientIdentification message.

Devices may be revoked by the provisioning server resulting in an
error message contained within the provisioning response. The CDM
core currently returns an error, but the CE CDM would map this to
an kUnexpectedError, which does not provide the information to the
CE client to react. This situation is not immediately recoverable,
but may provide certain apps to use a different DRM plugin if they
support such a thing.
Documentation and tests are needed.

GetDeviceInformation() and GetDeviceSignedCsrPayload() are added to
cdm_engine and crypto_session, so that they can be queried by DRM
plugin. This is to allow the wv drm HAL to be able to extract BCC and
CSR payload to build CSR for prov 4 device registration, such that we
don't need a separate RKP HAL to do this job.
Changes to the DRM plugin to use the exposed methods will be in the
coming CL.

For provisioning 4.0 devices, the DRM certificate serial number
was changing on a reprovisioning attempt or factory reset. The
app parameters sent up in the client identification name-value
pair field were being filtered out in provisioning requests.
This has been corrected for provisioning 4.0 stage 2
(DRM certificate request). There is no need to include them for
stage 1 (OEM certificate request).
The test case WvCdmRequestLicenseTest.ProvisioningSpoidTest
was created earlier to ensure that SPOIDs and DRM certificates are
stable. Unfortunately due to another bug b/250099615, the RKP service
was holding a connection to the Widevine TA for provisioning 4.0
devices. When native tests ran as their own process, L1 would fail
to load due to a connection failure and the test would run as L3.
The tests passed for provisioning 4.0 devices Pixel 7 and 8 when
they should have failed. This gave us a false sense of confidence
that the SPOIDs were stable.
For now a workaround is to run a shell command to kill the widevine
TA before running native tests.
$ adb shell pkill -f -9 widevine

For devices with a large number of usage entries, when restoring the
usage table a capacity check is performed. This checks that a new
entry can be created. This test was originally added as some devices
might enter a "stuck" state the table cannot be initialized.
To perform this test, a temporary crypto session is created and an
entry is created for that session. After successfully creating that
entry, the entry is deleted. However, because the session was left
open, the entry could not be deleted.
This change closes the capacity-check-session before deleting the
entry, as well as includes additional logs for helping future debugs.

1) Current and max HDCP capability when calls to decrypt or select
key failure due to insufficient or mixed HDCP levels.
2) Current, desired and default HDCP level when video contraints

Offline license not found errors are identified by CdmResponseEnum
347 (KEYSET_ID_NOT_FOUND_4). No addition file system information
is shared.
Checks for file existance use the stat command. The stat call can
return error codes from errno.h when the command fails.
These are now converted into sub error codes and returned along with
the offline license file not found error.
This also includes a change to log stat errors other than
ENOENT (no such file or directory) as a warning rather than verbose.

Removed the file "error_string_util.cpp" and its header, moving the
OEMCryptoResult to string converter to "wv_cdm_types.cpp". This extra

to the CDM itself.

If a change in System ID is detected, reprovisioning will be forced.

The default invalid entitled key session id was 0, which in fact could
be a valid value depending on how the key session id is allocated by the

OEMCrypto v17 introduced several new HDCP levels that OEMCrypto may
report; however, the CDM never updated to support them. The enum
values of the additional levels are no longer sequential with their
level of support (v1.1 is 7, and v2.1 is 3), this requires more
considerations when comparing the required HDCP levels (as specified
by the license) and current HDCP level supported by OEMCrypto.
The following rules were used:
1) HDCP_NONE is the absolute lowest level
2) HDCP_NO_DIGITAL_OUTPUT is the absolute highest level
3) HDCP_V1 is treated as equal to all V1.x levels
4) All other versions are based on their major-minor pairs

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
test printers in test_printers.cpp.
