There are situations where an offline license file will remain on the
system after it's usage entry has been deleted. This would result in
its key set ID being reported as present by the CDM, but any
operations acting upon it will result in an error.
The app should be able to remove the license without error, so long
as the license file exists and no other OEMCrypto operations fail.
This change introduces a new error code LICENSE_USAGE_ENTRY_MISSING,
which indicates that a license's usage entry cannot be found.
A new integration test checks that the CDM can handle the calls to
removeOfflineLicense().

This implements the CDM code changes necessary to take advantage of
Combined Decrypt Calls on OEMCrypto v16. The result of this is that
WVCryptoPlugin is much lighter now because it can pass the full sample
down to the core in one call, but CryptoSession is heavier, as it now
has to handle more complex fallback logic when devices can't handle
multiple subsamples at once.
This patch also removes support for the 'cens' and 'cbc1' schema, which
are being dropped in OEMCrypto v16. This fixes an overflow in the code
for handling those schemas by removing it entirely.
This patch also fixes the "in chunks" legacy decrypt path to use larger
chunk sizes on devices with higher resource rating tiers.

The WV client supports root of trusts as keyboxes or OEM certificates.
Devices with keyboxes use provisioning 2.0 protocol to provision
while those with OEM certificates use 3.0. L3 provisioning failures
occur if the L1 and L3 root of trusts differ.
The provisioning method is now retrieved and cached when the
security level is known, when the session is opened.
Earlier it was retrieved and cached at initialization time and
always set to the value of L1 OEMCrypto (if present). This led
to provisioning failures.

This change removes the usages of conditional compilation to support

sometimes the newer branch was kept.

* Build CE & Jenkins CDMs With BoringSSL from third_party/
Author: John W. Bruce <juce@google.com>
[ Merge of http://go/wvgerrit/37120 ]
Up until now, integrators have been responsible for providing a
compatible crypto library for use by the CE CDM. (either OpenSSL or
BoringSSL) After this change, this decision will no longer be in their
hands. The CE CDM build will always use the copy of BoringSSL in
third_party/, which will be statically linked with our library with
hidden visibility. This allows us to better control what crypto library
we use and will prevent continuing problems with trying to support both
OpenSSL and BoringSSL.
Unfortunately, BoringSSL began using C++11 in mid-2017, and we can't
support C++11 right now. Until we can, we need to use a C++11-free
version of BoringSSL for libssl. The CDM itself will continue to use a
recent BoringSSL, as it only needs libcrypto. But the unit tests that
need libssl have to use the legacy version.

devices that do not support C++11.
Once we support C++11 in the CDM again, this weight should be removed
and all targets should use the copy of BoringSSL in the kit/ directory.

Some unit tests were using a statically-linked CDM instead of a

Long-term, we would like to test both kinds of linkage. (See b/69548115
for that.)
Some unit tests were also using a dynamicaly-linked CDM that was named
such that it appeared to be statically-linked. This patch renames some

OpenSSL 10.1 has a small number of incompatible changes.

cdm.gyp depended on cdm/cdm.gyp which caused that plus some
additional issues.
These changes are necessary to support g++ version:

* Add CDM APIs for Handling Service Certificates.
Author: Gene Morgan <gmorgan@google.com>
[ Merge of http://go/wvgerrit/28064 ]
The responsibility for managing Service Certificates has been moved
out of the CDM. Instead, provide CDM and CdmEngine methods to generate
a service certificate request message, and handle a service certificate
response. The API client can use these calls if it needs to get the
service certificate from the License Server.
These functions assume the request and response are base64 (web-safe)
encoded (see b/37481392). Not all servers are operating this way yet.
Any adaptations for non-compliant servers is handled outside the CDM.
See test WvCdmEnginePreProvTest::ServiceCertificateRequestResponse in
cdm_engine_test.cpp for an example of this.
These changes also eliminate the stored init_data and deferred
license type which were used to perform a service certificate request
during a license request.

This is a potential fix for b/36656190. Set aside public
key on first call to get the public key, and use it afterwards.
This gets rid of extra calls to OEMCrypto_GetOEMPublicCertificate(),
which has side-effect of staging the OEM private key.
This also fixes a problem where the public cert string was
not being trimmed to match the size returned by
OEMCrypto_GetOEMPublicCertificate().

This CL adds a new variant of the OEMCrypto mock code that adjusts its
behavior based on a configuration file. This is intended for
testing.
For example, a tester can set current_hdcp to 2 in the options.txt
file, push it to the device, and verify that a license is granted for
HDCP 2.0. Then the tester can edit the value of current_hdcp to 1 and
push the file to the device. Playback should stop because the license
is no longer valid.
This variant uses a real level 1 liboemcrypto.so to push data to a
secure buffer. That means we can test playback for a license that
requires secure buffers on an Android device with real secure buffers.

Service Certificates are used in two places, provisioning and
licensing. The service certificate code depended on a session_id
to get and set the service certificate properties, but the session_id
was not available in the provisioning path.
This patch pulls out the property lookup by session_id dependency,
and passes the CdmImpl's property_set into the provisioning code, so
the service certificate can be read and written there.

* Corrects usage_table_header lifetime management. Earlier the
UsageTableHeader class was a singleton tied to the CdmEngine lifetime.

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

* Cdm Session and Engine interface clean up
[ Merge of http://go/wvgerrit/16387 ]
Key Set Ids have been removed from the CdmSession interface
(GenerateKeyRequest, Addkey) as they can be queried by an accessor.
The CdmEngine interface now allows one to specify or retrieve a session ID,
since both were not being used in a single call. Key set IDs are no longer
returned though GenerateKeyRequest as they was not being used.
* Generate key set ID when session is initialized
[ Merge of http://go/wvgerrit/16370 ]
Key set IDs are currently generated at different times in the
CdmSession lifecycle. Android generates key set IDs when the license
is received, while the CE CDM generates (or overrides them)
when the session is constructed.
The key set IDs are now generated when the session is initialized.
Key set generation cannot occur earlier as it has a dependency on
security level and in turn on crypto session initialization which
occurs when the session is initialized.
Depenencies on Session ID has caused other activities, construction of
PolicyEngine, CdmLicense, setting property CDM client sets to be
deferred from CdmSession constructor to Init().
Android will still retrieve the key set IDs after the offline license is
processed. For streaming requests, the key set will be
unreserved and discarded when the session is terminated.

* Extend CdmLicense's stored_init_data_
[ Merge of http://go/wvgerrit/14661 ]
CdmLicense will store init data when a server cert must be
provisioned. After provisioning, the original init data can be used
to generate the originally-intended license request.
To do this before, the caller had to call CdmSession's
GenerateKeyRequest with an empty InitializationData object. However,
the init data's type still had to be set, as did the license type.
This CL allows the caller to use a truly empty InitializationData
without a type. To permit this, CdmLicense now stores a full
InitializationData object, rather than just a copy of it's data field.
With this CL, the caller also avoid storing the original license type.
To accomplish this, CdmSession uses the already-set is_offline_ and
is_release_ flags from the original call to reconstruct the intended
license type. The caller uses the new type kLicenseTypeDeferred.
To facilitate storing whole InitializationData objects, they are now
copyable.
This ultimately simplifies server cert code for the new CE CDM.
* Store service certs in Properties
[ Merge of http://go/wvgerrit/14664 ]
This allows CE devices to mimic the Chrome CDM's behavior of sharing
server certs between sessions.
This also affects Android behavior. Previously, provisioned service
certificates were per-session, while explicitly-set service certs
were per-DRM-plugin. Now, both are per-DRM-plugin.
A DRM plugin is associated with a mediaDrm object. Content
providers will still be able to retrieve and use different
certificates. The change here requires an app, that wishes to use
different provisioned service certificates will have to use
multiple mediaDrm objects. This is an unlikely scenario.

* Reject session clobbering.
[ Merge of http://go/wvgerrit/14634 ]
This fixes a bug in I17de92b3e682c9c731f755e69466bdae7f560393 in which
sessions can be clobbered by a forced session ID. This bug manifested
in subtle test failures which involved repeatedly creating sessions.
This was traced to OEMCrypto not being terminated, then upward to a
leaked CryptoSession and CdmSession, and then finally to clobbered
session IDs.
To avoid the bug in future, first, reject duplicate session IDs.
Second, change the OpenSession API to make forced IDs explicit.
* Fix unit test namespaces.
[ Merge of http://go/wvgerrit/14622 ]
This fixes some odd errors that occur when linking multiple test
suites into one executable. When two object files both contain
a definition of wvcdm::MockCryptoSession, for example, one will win
silently and cause the other's tests to misbehave and/or crash.
The solution is to put all mocks into an anonymous namespace, since
each wvcdm::(anonymous)::MockCryptoSession is separate.
In order to avoid lots of repetitions of wvcdm:: in the anonymous
namespaces, all anonymous namespaces in unit tests now live inside
or the wvcdm namespace. This has been done even for tests which
are not currently using mocks.
