When offline licenses are restored, licenses and any renewals are processed.
License state evaluation occurs and notifications are sent to listeners.
If the license is expired, which is likely if a renewal is present,
the license state will transition to expired. Transitions out of
expired state are not allowed and the renewal has no effect.
If we work around this by allowing transitions out of expired state,
listeners will get notifications that keys have expired and then that are
usable soon after. To avoid delivering erroneous notifications we delay
evaluation of license state while the license and renewal are being processed.
Evaluation occurs at the last stage of license restoration when playback
information from the usage table is being restored.
This only need to occur for when licenses are being restored. In other
cases when a license or renewal is received, license state evaluation
and event listener notification needs to occur immediately.

Clang and GCC allow for warnings against the arguments for printf-like
functions (e.i. LOGx). These validate that the format type specified
in the format string match the corresponding argument type.
Most of the time, format specifer errors are benign; hence why they
haven't been seen as an error so far. However, with the enabling of
specifier warnings and the enabling of warnings as errors on certain
platforms, these existing errors need to be addressed.
This CL enables format specifier warnings for most of the Widevine
code, with the OEMCrypto L3 implementation which has a single error
which requires a fix in the haystack code before being fixed in the
Widevine branch.
Strict format string warnings are not enabled for non-LP64 systems.

The OEMCrypto method for usage table capacity can return zero to
indicate that the usage table size is not explicitly limited. The
CDM must handle this case with regard to the CDM's usage table
management and information querying.
The usage table initialization tests are extended to include cases
where the table does not have a defined limit.
AddEntry() was missing call to update the usage table header after

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.

When an offline license is reloaded, if it does not have a usage entry
to indicate when the rental clock was started, the start time defaults
to 0 in the ODK library (in OEMCrypto). This CL changes the code to
start the rental clock in this case. It does this by signing a dummy
message, which triggers the ODK library to start the rental clock.

After changes made to how the usage table is defragged by the CDM,
it was determined that there is no use in selecting more than a single
entry from the usage table to evict. The only failure that can occur
when evicting an entry is if the last entry is in use, in that case,
evicting other entries will still result in a failure.
This change cleans up the LRU algorithm and test cases to reflect
the new functionality.

The CDM was using unique CDM error codes for the various cases
where OEMCrypto would return INSUFFICIENT_RESOURCE. However, these
error codes were being incorrectly mapped at the Android level,
resulting in incorrect errors in the MediaDRM layer.
At no point does the CDM handle different INSUFFICIENT_RESOURCE_x
within the same case, as such the use of unique codes are limited.
This CL removes the unique codes, and unifies them under the same
CDM error code.
This CL also extends SelectKey to handle error codes returned by
LoadEntitledContentKeys.

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.

that change affects the Android code, so I have filtered this
description.)
By default, the CDM builds with Clang on Android and on developers' dev
boxes. The buildbot builds most of the code with an old version of GCC.
However, recent versions of GCC were refusing to build our code for a

version of GCC 9 included on gLinux workstations can compile the CDM.
The only change that affects Android is that a variable was being set
but never read in one place.

When processing a license release, the license is not loaded, so
OEMCrypto does not know nonce version information for the core
message. It assumes that all license releases are v15, so it is not an
error for a license release to not have a core message.
This CL also adds some extra logging to tests so that we can track
content id and the pssh. This CL also updates some of the test content
policies when running the local license server. The local license

Changes to how the usage table method InvalidateEntry() behaves
required additional changes to CDM code that uses this method.
This involved some refactoring to AddEntry(), moving the LRU
related code to its own function.
A few unittests had to be changed / removed as the moving
multiple entries changes expectations of several existing tests.
Several additional helper methods have been created to improve
readability. These include getters for information about the
usage table, a method for releasing stale entries, and a method of
recording LRU metrics.

There was an issue with DeleteEntry() where it would result in an
invalid table state if shrinking the usage table when the number of
sessions is at its max.
This required changing how the usage table invalidates entries. Now,
after invalidating an entry (marking an entry as kStorageTypeUnknown)
the table is defragmented if specified to.
Defragmentation involves:
1) Move valid entries near the end of the table to the position of
invalid entries near the front of the table.
2) Shrinking the table to cut off trailing invalid entries.
This change updates the existing tests to pass, but still needs new
tests for some of the edge cases.
