5606e7dae3 Upgrade MOCK_METHOD to googletest 1.10
(This is a merge of http://go/wvgerrit/139989.)

Googletest added a new, more powerful MOCK_METHOD() macro in 1.10. This
patch updates all our usage of the old MOCK_METHOD family to the new
macro. Full details can be found at
https://github.com/google/googletest/blob/release-1.10.0/googlemock/docs/cook_book.md#creating-mock-classes
but in brief, the new MOCK_METHOD() replaces the entire old MOCK_METHOD
family and has the following advantages:

1) No need to count parameters or update the macro name when changing
   parameters.
2) No need for a different macro for const methods.
3) The ability to specify override, noexcept, and other function
   qualifiers.
4) The macro order is now the same as C++ method definition order:
   Return Type -> Name -> Arguments -> Qualifiers

In addition to upgrading all our usage sites to the new macro, the
addition of the override qualifier to our MOCK_METHODs helped uncover
several cases where we were using MOCK_METHOD to override methods that
didn't exist. This is a great example of why the override qualifier is
so useful. These places have been updated, by removing the invalid and
unused mock method.

31faf51933 Fall back to L3 if L1 has test keybox
Merge from Widevine repo of http://go/wvgerrit/142150 (part 2)

For an EVT device, without a keybox or with a test keybox, we want it
to fall back to L3. However, when running the unit or integration
tests it should continue running tests with test keybox. This will
allow us to test L1 oemcrypto on an EVT device, while still using an
EVT device for dogfooding video content at the L3 level.

bfd299a4be Add missing override keywords
(This is a merge of http://go/wvgerrit/139629.)

This patch fixes several places where the override keyword was missing.
These were found when future patches that enable stricter checking of
the override keyword were enabled. There are two basic categories of
missing override:

* Destructors found to be overriding a virtual destructor without using
  the override keyword.
* Test methods overriding methods on test-only or mock objects.

Some of these were previously marked as virtual, following our pre-C++11
style guidelines, but this is not necessary now that we have override.

8574a4b98c Update handling of move-only types in DeviceFiles unit test
(This is a merge of http://go/wvgerrit/139569.)

The unit test for DeviceFiles previously had to work around googlemock's
lack of support for move-only types. Now that we have upgraded to
googletest 1.10, we can use move-only types directly via the ByMove()
utility, removing the need for this workaround.

59f0f7cd36 Added new error code OEMCrypto_ERROR_INVALID_KEY.
[ Merge of http://go/wvgerrit/138606 ]

The new error code OEMCrypto_ERROR_INVALID_KEY is to replace the now
deprecated error code OEMCrypto_ERROR_INVALID_RSA_KEY.  This error code
serves the same purpose of OEMCrypto_ERROR_INVALID_RSA_KEY, but may be
appied to RSA, ECC and Twisted-Edward ECC keys.  In general, this error
code is to indicate that a key is poorly formatted / unparsable, used in
an operation without allow permissions, or used in an operation that it
cannot be association (RSA signing with an ECC key).

Going forward, new OEMCrypto implementation should use
OEMCrypto_ERROR_INVALID_KEY in place of OEMCrypto_ERROR_INVALID_RSA_KEY.
The CDM will continue to support both error codes.

c45559177a Fix -Wshorten-64-to-32 errors in test code

This patch fixes code that would trigger -Wshorten-64-to-32 by
implicitly narrowing a variable from 64 to 32 bits. Most of the time, it
does this by making the implicit conversion explicit. Occasionally,
where it makes sense, it does this by expanding the code to operate on a
64-bit value.

This patch removes LicenseKeysTest::NumContentKeys(), which no one was
using, as all the tests access content_key_count_ directly.

eb846100d4 Update OTA Keybox tests
Merge from Widevine repo of http://go/wvgerrit/135982

The basic test was failing when using the testbed oemcrypto
because the testbed deletes its keybox on each
initialization. The test would terminate and re-initialize
oemcrypto whenever all the crypto sessions are deleted. This
has been fixed by holding a crypto session alive until the
end of the test.

SystemFallbackPolicy to relay provisioning status between engines.
The provisioner will handle message wrapping and unwrapping of the
raw OTA keybox request / response into the SignedProvisioningMessage
which is sent to/received from the provisioning server.

Integrated OKP into CDM Engine

[ Merge of http://go/wvgerrit/133804 and http://go/ag/15646376 ]

Extended the functionality of the CdmEngine to check if the device
requires OKP and to initialize OKP resources if required.  The
functionality of OpenSession() and GetProvisioningRequest() have been
the most affected.  If OKP is required, these methods will signal to
the app that provisioning is required and will return an OKP request.

Once a device is provisioned, the OKP data is cleared away and the
CdmEngine will resume normal operation.  Engines created after a
device is provisioned will immediately enter normal operations.
The exception is for CdmEngines which failed to perform OKP for some
reason and are still running.  Those apps will need to restart before
gaining access to L1 operations.

The keybox validation needs to be done separately from initializing

If L1 loads, but the keybox is missing, the initialization should
succeed. When the keybox is validated, the adapter should try to look
for a keybox on the filesystem. if none is found, it should either
return NEEDS PROVISIONING or an error.

The basic test was failing when using the testbed oemcrypto
because the testbed deletes its keybox on each
initialization. The test would terminate and re-initialize
oemcrypto whenever all the crypto sessions are deleted. This
has been fixed by holding a crypto session alive until the
end of the test.

Integrated OKP into CDM Engine

[ Merge of http://go/wvgerrit/133804 and http://go/ag/15646376 ]

Extended the functionality of the CdmEngine to check if the device
requires OKP and to initialize OKP resources if required.  The
functionality of OpenSession() and GetProvisioningRequest() have been
the most affected.  If OKP is required, these methods will signal to
the app that provisioning is required and will return an OKP request.

Once a device is provisioned, the OKP data is cleared away and the
CdmEngine will resume normal operation.  Engines created after a
device is provisioned will immediately enter normal operations.
The exception is for CdmEngines which failed to perform OKP for some
reason and are still running.  Those apps will need to restart before
gaining access to L1 operations.

The keybox validation needs to be done separately from initializing

If L1 loads, but the keybox is missing, the initialization should
succeed. When the keybox is validated, the adapter should try to look
for a keybox on the filesystem. if none is found, it should either
return NEEDS PROVISIONING or an error.

68187b9f02 Fix -Wshorten-64-to-32 errors in BoringSSL interactions
(This is a merge from the Widevine Repo of http://go/wvgerrit/134310.)

This patch fixes code that would trigger -Wshorten-64-to-32 by
implicitly narrowing a variable from 64 to 32 bits. Most of the time, it
does this by making the implicit conversion explicit. The cause of most
of these is that OpenSSL uses "int" for the length of things rather than
size_t. (While BoringSSL sometimes uses int and sometimes uses size_t.)

One exception is LogBoringSSLError(). We have a couple copies of this
function around, and they varied slightly. This patch brings them all
in-line, which conveniently also removes any code in them that would
deal with integer variables.

GetRandBytes() now takes a size_t and downcasts to BoringSSL's native
int internally, so that callers can pass in a size_t value as they would
expect.

There's also an interesting case in oec_session_util.cpp. Because
BoringSSL and OpenSSL disagree about the width of an error code, we have
to use the "auto" type for a temporary variable that holds an error, in
order to retain compatibility with both.

Due to uncertainties of when the provisioning service will

If the feature does not launch in time, existing DRM certificates
will expire and be replaced. Offline licenses associated with these
expired DRM certificates will fail to load.

Expiration of legacy certificates will be reenabled at a later time.
The main portion of feature, the issuing of new DRM certificates with
expiration time will still be supported.

884550333d New usage entries are moved lower after creation.
[ Merge of http://go/wvgerrit/124004 ]

When the CDM creates a new usage entry for an offline or streaming
license, the new entry is immediately moved to the lowest available
entry index that has been marked as vacant (kStorageTypeUnknown).

When a license is released, its meta data that is managed by the CDM
is cleared; however, the usage entry's index is marked vacant, but it
is not released.  This creates wasted entry space in the usage table.
Unfortunately, defragging the table is computationally expensive and
may not be able to actually free up much space depending on when it
is performed.

For a typical user, this will likely not be an issue as the table
can get quite large compared to the number of licenses an app uses
and the table is partially cleaned on each boot.

GTS tests, however, have reached a point where they fill the usage
table before all tests are complete.  This is causing many unexpected
failures for devices.  Most of these tests release their license, but
the CDM never reaches a state where it can clean up the table.

By moving newly created entries to the lowest available index directly
after creating the entries, the table never needs to grow unless all
entries are in use.  Clean up is now almost never required.

023b06eded Check for open session when initializing usage table.
[ Merge of http://go/wvgerrit/122984 ]

There was an issue encountered by some vendors with how the usage
table was initialized on some devices.  Previously, the CDM would
open an OEMCrypto session first, then initialize the usage table
(loading existing or creating a new one).  On these devices,
OEMCrypto_CreateUsageTableHeader() and OEMCrypto_LoadUsageTableHeader()
would fail if there were any open sessions.

This CL changes the initialization process to create/load the usage
table before opening an OEMCrypto session.

This change also lays the ground work for another usage table fix
to address GTS tests failure.

In the process, several of the functions for the usage table have been
split up into smaller chunks of code.  This required additional changes
to the usage table unittest to keep them up to date.
