Devices with baked-in DRM certs cannot be reprovisioned. As such, we
must protect them against being unprovisioned. Currently, our unit
tests break such devices by attempting to unprovision them. This patch
adds code to block the Unprovision() call on these devices.

The CL moves several files used by oemcrypto and cdm into a common
subdirectory, so that it may more easily be shared with partners.
The CORE_DISALLOW_COPY_AND_ASSIGN macro was moved to its own header in
the util/include directory.
This CL removes some references to the mock from other code, and puts
some constants and types, such as the definition of the keybox, into a
header in oemcrypto.

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.
A case of acquiring a lock while one was held in GetProvisioningId()
has also fixed.

Key rotation is not yet supported.
The key statuses are updated from a license. The
mechanism expects content keys tro come in a license.
For entitlement licenses, the content keys come in the
init_data.
This code does not yet support the key rotation event.
(A new pssh with wrapped keys is a passed to the cdm)
The policy engine/key status mechanism needs to be
updated to handle updated from the init_data.
For now, the cdm builds a license with a key container
with the content keys and used that to call
PolicyEngine::SetLicense to setup the policy engine
and key statuses.

* Get System ID From OEM Cert
Author: John W. Bruce <juce@google.com>
[ Merge of http://go/wvgerrit/37940 ]
(This is a merge of http://go/wvgerrit/30220 . However, it has been
significantly modified in the merge due to needing to support both
OpenSSL and BoringSSL.)
Previously, extracting the system ID was only supported on Keybox-based
systems. This patch adds support for extracting the system ID from the
OEM Certificate chain on Provisioning 3.0 devices. This is done by
getting the Widevine intermediate cert from the chain, finding the
Widevine System ID extension in that cert, and extracting the value.
The code that does the extraction is separate from any code that calls
OEMCrypto so that it can be unit-tested in isolation. This patch adds a
crypto_session_unittest test to do this unit-testing.

[ Merge of http://go/wvgerrit/37900 ]
I put both changes in this CL since I have to generate Level3 libraries
for both anyways. The first change involves shifting from using a
prebuilt static library to using an obfuscated source library output
from the Haystack tool on google3. The second change is from here:
https://critique.corp.google.com/#review/176536782, and addresses
b/69387416. Since the cache_flush function wasn't being used, the

The code is platform specific so it can be enabled and the precise
format configured on a per-platform basis.
As an example, here is a log on android before the change,
11-01 02:48:48.658 D/WVCdm (32198): CryptoSession::Open:

* Deprecate using keyboxes as identification
Author: Rahul Frias <rfrias@google.com>
[ Merge of http://go/wvgerrit/36740 ]
Previously some platforms supported using keyboxes rather than
certificates as the identification tokens in the license request
message. All platforms that share core CDM code of the master branch now
either provision using a keybox and use a DRM certificate or an
OEM certificate as identification. No future usage of keyboxes
as identifying tokens is planned.

is always set to true, the negative code paths are never taken and
can be removed.

Previously, when moving the BoringSSL source within the tree, I was not
able to verify that I had not broken the NDK-compatible makefiles used
by Fastball because that build is broken on master. I had to make a
best-guess as to how they should be updated and hope.
Now, however, I have been informed that the OEMCrypto Variants also use
these makefiles, and I have been able to use that build to find where I
broke them and get them fully working.

I want to make updating BoringSSL as simple as possible for us going

wiping them out in a separate change before I upload any other changes

* Gyp cleanup and OpenSSL v10.1 support.
Author: Gene Morgan <gmorgan@google.com>
[ Merge of http://go/wvgerrit/36001 ]
OpenSSL 10.1 has a small number of incompatible changes.
A desktop system upgrade exposed some issue in the build scripts.
Specifically, the linux build was using both third_party/protobufs (2.6.1)
and the version installed on the system (3.0 in this case). The linux
cdm.gyp depended on cdm/cdm.gyp which caused that plus some
additional issues.
These changes are necessary to support g++ version:
g++ (Debian 6.3.0-18) 6.3.0 20170516
Also did some cosmetic rework on run_current_tests to make it easier
to figure out what is going on when something fails.

* Resolve intermittent decrypt error.
Author: Jeff Fore <jfore@google.com>
[ Merge of http://go/wvgerrit/35720 ]
The CdmSession's closed state was not properly
initialized resulting in intermittent
SESSION_NOT_FOUND_FOR_DECRYPT errors.
In CdmEngine::Decrypt the session is looked up by
the key id. A list of open sessions is acquired
by calling CdmSessionMap::GetSessionList and each
session in the list is queried to see if it has
the key.
In building the list in CdmSessionMap::GetSessionList,
sessions are only added to the query list *if* the session
is not closed.
The closed status was not initialized and during testing
the query list would not contain the session causing
CdmEngine::Decrypt to return SESSION_NOT_FOUND_FOR_DECRYPT
resulting in the ce cdm api returning widevine::Cdm::kNoKey.

Author: Fred Gylys-Colwell <fredgc@google.com>
[ Merge of http://go/wvgerrit/24729 ]
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.

Previously, extracting the system ID was only supported on Keybox-based
systems. This patch adds support for extracting the system ID from the
OEM Certificate chain on Provisioning 3.0 devices. This is done by
getting the Widevine intermediate cert from the chain, finding the
Widevine System ID extension in that cert, and extracting the value.
The code that does the extraction is separate from any code that calls
OEMCrypto so that it can be unit-tested in isolation. This patch adds a
crypto_session_unittest test to do this unit-testing.

UsageTableHeader class was a singleton tied to the CdmEngine lifetime.

The UsageTableHeader class is now associated with OEMCrypto

These get allocated/deallocated on OEMCrypto Initialization/Termination

* UsageTableHeader requires OEMCrypto, file read/writes and

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

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

Starting with OEMCrypto v12, we are guaranteeing to integration partners
that the buffers passed to OEMCrypto_DecryptCENC and
OEMCrypto_CopyBuffer will not be more than 100KiB (102400 bytes) in
size. For requests larger than this, we will first try to send the
buffer to OEMCrypto anyway. (in case the integration supports buffers
larger than the minimum) In the event that the buffer is rejected, we
will break it up into 100KiB chunks and send them down individually for
decryption.
Breaking a subsample into smaller subsamples necessitates knowledge of
how to update other decryption parameters (like the offsets and the IV)
that previously the CDM Core has not needed to know about. Until now,
this knowledge lived in the glue layer on the Android CDM and nowhere
on the CE CDM. Now, the CryptoSession has a subset of this knowledge, in
order to break up buffers successfully.
For testing purposes, the Mock OEMCrypto has been modified to only
support the smallest buffer size. In order to make sure the chunking
code was being exercised by them, the CE CDM tests had to have the
amount of data they decrypt increased by several orders of magnitude. To
contain this growth, I have moved the test data to its own file.
Bug: 31381719
Test: Ran the updated CE CDM integration tests
Test: Modified the OEMCrypto dynamic adapter to pretend both L3 and L1
only support 100KiB buffers on a Marlin and a Ryu. Confirmed that the
GTS H.264 tests (which have subsamples over 100KiB) passed still. A
similar test was attempted on Fugu but Fugu cannot pass these tests even
without this change present.

This cleans up our includes to be in Google Style Guide order and in
alphabetic order, for the parts of the code that are expected to
follow Google Style.
This also converts places in our code that were including C headers
in the C++ style (i.e. <cstring> instead of <string.h>) to use C style
instead. This is because, although it was not causing problems for us
yet, on Android these actually include different headers. (<cstring>
is provided by libcxx, while <string.h> is provided by Bionic)
Lastly, this change puts all headers that do not come from within our
project in <brackets> instead of "quotes," which was not being done
consistently.
This change is explicitly NOT trying to standardize the spacing of our
header includes. I have tried to respect, in each file, the spacing
style already present.
