e538c96131 Save and retrieve key information from licenses and usage records
[ Merge of http://go/wvgerrit/120512 ]

Wrapped DRM private keys are loaded when a key request is made or when
offline/usage sessions are restored. They were earlier loaded when a
session was opened.

For streaming sessions, key material will be fetched from the default
or legacy certificates and loaded when a key request is made.

For offline and usage sessions, key material may be retrieved from
license or usage records if available. If not available, information
associated with the legacy certificate will be loaded.

Certificate and wrapped keys are also written out when an offline
license or usage record is saved.

8543b4c903 Delay license state evaluation for offline licenses
[ Merge of http://go/wvgerrit/106325 and http://go/ag/12644840 ]

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.

f22cd20466 Enabled log formatting warnings.
[ Merge of http://go/wvgerrit/105025 ]

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.

7f347cd59f Adjust nonce for v15 servers
Merge from Widevine repo of http://go/wvgerrit/102783

When OEMCrypto is v16, but the license server is v15, we should not
create a new nonce for a license renewal. However, the request does
need a nonce or the license server will not generate a valid key
control block. So we should use the nonce that came from the original
license.

760bf71908 License release does not use core message
Merge from Widevine repo of http://go/wvgerrit/99843

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
server is only used for debugging problems.

63b2ea86d9 Allow CE CDM to Create Sessions Without a Service Certificate
(This is a merge of http://go/wvgerrit/84510)

When the CE CDM 3.5 behavior around service certificates was originally
implemented, it allowed sessions to be created if a service certificate
had not yet been installed, in keeping with the EME spec. However, the
service certificate in use at session creation time was cached, and so
there was a bug where any sessions open before a service certificate was
installed would never be updated with any future service certificates.
The code also caused problems for Android. When it was merged to master,
it was fixed to simply not allow session creation on CE CDM without a
service certificate. However, this created an impedance mismatch between
the CE CDM and EME that has caused pain for Shaka Player Embedded,
Chrome, Chromecast, Fuchsia, and likely every partner that is trying to
implement a fully-compliant EME stack on top of CE CDM.

Removing the code that blocks session creation without a service
certificate is easy. Fixing the bug that motivated it is not. Removing
the caching is not possible because Android needs it for certain
behavior on its end. So instead, the CE CDM will have to iterate over
all open sessions and update their service certificates if the installed
service certificate changes.

ca00dc7ae4 Simplify How Request ID Indices are Generated
(This is a merge of http://go/wvgerrit/70667)

Request ID Index generation has historically worked by incrementing a
shared variable in one place and reading it in another place and
trusting the fact that CdmLicense calls these operations in a certain
order and only once per session to give each session a unique value.
This patch cleans this up a bit, having each session store the current
Request ID Index at the same time as it stores its Request ID Base. This
guarantees that each CryptoSession will receive a unique but stable
combination of Base and ID rather than relying on the calling pattern.

Since all this generation happens during the same function, the full
Request ID can be generated up-front and stored, making
GenerateRequestId() no longer necessary.

This patch also simplifies the threading story around this shared state
by using a std::atomic<uint64_t>. Bringing the code that interacts with
the shared state together into one place and replacing it with atomic
operations will simplify locking around this code when CryptoSession
locking is revamped in a future patch.

4af5aaf18a Add test base that catches nonce flood
Merge from Widevine repo of http://go/wvgerrit/56520

This CL adds a test base that installs a test keybox and catches nonce
flood errors for all CDM tests.

In order to do this, a new class is added called a
CryptoSessionFactory.  The default factory just creates a new
CryptoSession.  All places in the code that create a new CryptoSession
now call the static method MakeCryptoSession, which uses the current
factory to create a CryptoSession.  If MakeCryptoSession is called and
there is no current factory, a default factory is created.

The CryptoSession constructor is now private, so that we do not
accidentally try to create one without using the factory.

For the new test base, we first create a special test
CryptoSessionFactory that creates a TestCryptoSession.  The test
factory catches the first call to MakeCryptoSession and injects an
installation of the test keybox after OEMCrypto_Initialize is called.

The TestCryptoSession injects a sleep statement and a retry whenever

6000f834a0 Entitled Key Management
Merge from Widevine repo of http://go/wvgerrit/53883

Note: this CL does not modify license_key_status.cpp because the
previous CL already included those changes.

OEMCrypto v14 only supports one entitled key per entitlement key at a
time. Unfortunately, some partners have use cases that require using
old entitlement keys after the new keys have been loaded. Most
notably, when a key rotation occurs, the new PSSH will often be loaded
before the playback position catches up to the PSSH in the stream,
meaning that decryption will need to continue using the old keys for a
bit.

To fix this, EntitlementKeySession now caches the entitled keys when
they are loaded and only loads them under their matching entitlement
key when SelectKey() is called. This ensures that the right entitled
key is loaded for a given entitlement key before decryption.

The entitlement key integration tests have been updated to verify that
the old entitled keys still work even after loading new entitled keys.
Also, several places in the code that assumed loading new entitled
keys would wipe out the old keys have had to be modified.

9ae7489938 Add basic handling for entitlement keys in a license.
Merge from Widevine repo of http://go/wvgerrit/41834

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.

  [ Merge of http://go/wvgerrit/39460 ]

  This change removes the usages of conditional compilation to support
  both BoringSSL and OpenSSL, as well as to support multiple versions of
  the OpenSSL API. All code is now compiled against one of the two
  versions of BoringSSL in third_party/.

  Note that in some cases, the kit/ and legacy_kit/ versions of BoringSSL
  had different APIs, so when removing the OpenSSL version compatibility
  conditional compilation, sometimes the older branch was kept and
  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.

  Author: Srujan Gaddam <srujzs@google.com>

  [ Merge of http://go/wvgerrit/39220 ]

  Bug: 65165076

  Modified seed generation to use an xor of clock_gettime and
  client-implemented code to supply random seeds to the RNG. Modified the RNG
  as well to use xoroshiro128+ instead of xorshift, since it uses more
  than one seed/state (which are 64-bit) and has higher "statistical quality".
  The default implementations for the seed generation use /dev/urandom.

* Configure base path for Level3FileSystem

  Author: Srujan Gaddam <srujzs@google.com>

  [ Merge of http://go/wvgerrit/39506 ]

  This is in response to b/70354006. This change makes the
  Android Level3FileSystem use the existing properties method
  GetDevicesFilesBasePath for binderization. The same is done for the
  Linux implementation.

* Add legacy_kit/ to BoringSSL Directory

  Author: John W. Bruce <juce@google.com>

  [ Merge of http://go/wvgerrit/38861 ]

  This adds a second copy of BoringSSL to the third_party/boringssl/
  directory. This second copy is pinned to the last revision of BoringSSL
  not to require C++11 and is not updated by the UPDATE_BORINGSSL.sh
  script. This second copy will be used to provide libssl to the tests on
  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.

  Bug: 67907873

* Use Shared Libraries for Unit Tests

  Author: John W. Bruce <juce@google.com>

  [ Merge of http://go/wvgerrit/38860 ]

  Some unit tests were using a statically-linked CDM instead of a
  dynamically-linked one. (Or, in one case, trying to link both ways into
  the same binary.) For now, we need to only link dynamically, so that the
  unit tests and the CDM can use different versions of BoringSSL.

  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
  targets to make the linkage clearer.

  The code has been restructured to allow encryption of client

  when server side changes have been made (b/69427217).

  * Additional information is included in the Client Identification
    portion of the provisioning request.
  * Client identification will be encrypted with a service
    certificate provided by the app/client. Platform changes
    to enable passing this to core are needed. If a service certificate
    is not provided, a default one associated with the production Keysmith
    will be used.
  * Switched APIs in CdmEngine to take a service certificate for
    provisioning rather than licensing. Service certificates for
    licensing are session based and passed as properties from platform
    code.

  These changes allow for service certificates to be specified on a

  This also allows for a service certificate request and response handling
  when allowed on the platform, when privacy mode is enabled and a service
  certificate is not provided.

  Request license tests accept a service certificate command line
  parameter in hex (ascii). Earlier it expected it in binary.

  usage table file names are replaced with constant needles. Furthermore,
  a state needle was added that removes the OldUsageTable file. In
  addition, this CL includes removals of method references that are now
  stale due to the introduction of change
