1857da2c8c Correct offline license handling
[ Merge of http://go/wvgerrit/28261 ]

Licenses (offline, secure stops) that contain provider session tokens
are handled securely using usage tables. A recent fix did not correctly
handle offline licenses that do not contain a provider session token and
are not handled by the TEE.

5da8da58f6 Corrections for big usage table support in L3
[ Merge of http://go/wvgerrit/26421 ]

* Corrects usage_table_header lifetime management. Earlier the
  UsageTableHeader class was a singleton tied to the CdmEngine lifetime.
  With SPOIDs there might be multiple concurrent CdmEngine objects.
  The UsageTableHeader class is now associated with OEMCrypto
  lifetime. There are two UsageTableHeader objects one for each L1 and L3.
  These get allocated/deallocated on OEMCrypto Initialization/Termination
  respectively.
* UsageTableHeader requires OEMCrypto, file read/writes and
  metric gathering to perform its required functionality. Because of the
  lifetime changes, CryptoSession, DeviceFiles and MetricsGroup objects
  need to passed to the methods rather than at Creation time.
* Miscellaneous fixes, when moving or deleteing entries.
* Adds usage_table_header_unittests.
* Addresses failures with request_license_test with secure stop in L3.

d751e81790 Fix GTS testL3PlayHDCPV* tests.
These tests verify whether a L3 device respects the HDCP policy set in the
license request. L3 device should only play the clear lead, and stop at
encrypted content. MeidaDrm should throw an ERROR_INSUFFICIENT_OUTPUT_PROTECTION
exception. This is because L3 device always returns current HDCP connection
status as HDCP_NONE.

This CL modifies the policy engine CanDecryptContent method to return
CdmResponseType instead of a boolean, so the app can generate the correct
error response if HDCP constriants are not met.

02fe2ef693 Fix deadlock when pending key release sessions are deallocated
[ Merge from http://go/wvgerrit/27261/ ]

Sessions created to release keys are periodically cleaned up if the
key release operation does not complete within a specific

through the timer thread. This would result in deadlock as a mutex
was taken twice.

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.

8513b71499 Hash OEM Certificate
(This is a merge of wvgerrit/25582)

Provisioning 3.0 devices that do not use SPOIDs have been returning
their full OEM Public Certificate as their device ID. While this is not
a security concern, (it is a PUBLIC cert) the cert is many times larger
than applications are likely expecting. (several kilobytes vs. just a
few bytes) This patch hashes the OEM Public Certificate to produce a
smaller value, but only when it is being provided out of the CDM to a
caller.

df0dad5311 Enable 64-bit Android Builds
(This is a merge of go/wvgerrit/23686)

This patch removes the makefile lines that previously prevented the
Widevine DRM Plugin from being built as 64-bit on Android. 64-bit
builds are now fully supported.

Only one piece of CDM code has had to change. Due to a bug in
libprotobuf before v3.0, int64 values from protobufs are technically a
different type from int64_t values in code on some 64-bit
architectures. Both have the same in-memory representation at runtime
but are seen as distinct types by the compiler. The compiler will
automatically convert in most places, but template instantiation is
not one of them, so a few places that passed a Protobuf int64 directly
into a template had to be modified.

Please note that tweaks to the mediadrmserver (not covered by this
patch) are needed in order for it to run as 64-bit and load 64-bit DRM
Plugins. Please also note that, as we have no 64-bit L1 OEMCrypto on
any devices, using the 64-bit mediadrmserver and Widevine library will
make your device fall back to L3 for the time being.

synchronizes access to usage table header and associated data-structures
and controls when they are read in or written out to non-secure persistent
storage. Upgrades from a fixed size usage table (supported by previous
versions of the OEMCrypto API v9-12) are handled by this class.

e75d3a6512 Revise usage entry metadata
[ Merge of http://go/wvgerrit/23742 ]

In OEMCrypto V13, usage table header and usage entries are stored in
persistent non-secure storage and loaded and unloaded from the TEE.
Information needs to be maintained to assist finding the associated license
or usage information. This information has been revised for usage information
to use key set id and usage info file name rather than provider session
token and app id.

The app id is stored in a hashed form (usage info file name) and was not
extractable during the upgrade process to OEMCrypto V13. Due to this
DeviceFiles UsageInfo routines have switched to use usage info file name
rather than app id as a key.

b384408dd2 Persist usage entry number
[ Merge of http://go/wvgerrit/23741 ]

Usage entries and usage entry numbers need to be stored with license
and usage information, to facilitate loading usage entries when offline
licenses/usage information are restored or prepared for release.

Test: Validated by running unit/integration tests on angler.

db6df99db1 Add usage support query method
[ Merge of http://go/wvgerrit/23522 ]

A helper method has been added to CryptoSession to determine whether the
TEE supports usage tables, usage table headers+entries or does not
provide any support for persistent licenses.

In addition
* CryptoSession now supports deletion of multiple
  usage entries rather than a single one.
* Typedefs have been added for usage table headers and entries

6d617e2be4 Implement Cdm::listStoredLicenses()
[ Merge of http://go/wvgerrit/23600 ]

This adds a new entry to IStorage:: -

  bool list(std::vector<std::string> file_names)

It returns the name of each file in the (origin-specific) file system.

b/34628115

Uses the current file system (origin-specific) bound to the CDM. Returns
the list of stored licenses (key_set_ids) in vector output parameter.

Test: verified by unittests on angler.
