46eecb6b80 Add a metric decorator around cdm engine
[ Merge from http://go/wvgerrit/69105 ]

This adds a metric collecting decorator class around cdm engine. This
implementation uses a templated decorator. The decorator enables:

1) Wrapping the CDM Engine methods to capture timing and error
information.
2) Allows use of a mock CDM Engine for testing.

Test: Unit tests. GPlay manual testing and GTS tests.

a1b5b42d55 Add a Reader-Writer Lock
(This is a merge of http://go/wvgerrit/70666)

We need a reader-writer lock implementation in order to make use of the
new threading guarantees in OEMCrypto v15. However, we do not have
access to an STL reader-writer lock due to only being on C++11. This
patch adds a home-grown reader-writer lock, as well as tests to verify
that its behavior is sound.

700ee5160a Add session metric pruning.
[ Merge of http://go/wvgerrit/65983 ]

Add support to drop closed metrics in order to save space for
long-running applications (and CdmEngine instances). The code now keeps
only a limited number of metrics collections after the session is closed.
As a session (and its metrics session) is closed, the oldest, closed metrics
session is dropped. This means those metrics will not be reported nor
accessible in the client.

* 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.

* Use source android level3 + add cache_flush call

  Author: Srujan Gaddam <srujzs@google.com>

  [ 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
  execution on Angler gave inconsistent segfaults, which this CL fixes.

  Verified on Angler, Sailfish, and Linux.

  11/27/17: Added mips and mips64 libraries.

* Make CDM result codes constexprs

  Author: Rahul Frias <rfrias@google.com>

  [ Merge of http://go/wvgerrit/38280 ]

  The values in the enumeration list of CdmResponseType error codes
  were earlier implicit. Comments were added to denote the actual
  values. This changes to make it fixed values, which makes it slightly
  more error prone, but cleaner when errors are retired.

* Change watchdog timer to 2 minutes

  [ Merge of http://go/wvgerrit/36340 ]

  This relaxes the watchdog timer around the level 3 oemcrypto
  initialization to 120 seconds.  There are also a couple of new log
  messages at the end of initialization and at termination.

* Automatically generate log location information

  Author: Rahul Frias <rfrias@google.com>

  [ Merge of http://go/wvgerrit/36563 ]

  Currently class and method names are manually added to each log message
  in the CDM on android and some other platforms. This change prepends
  log messages with file name, line number and function name automatically.

  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:
  Lock: requested_security_level: Default

  and after,

  11-01 02:48:48.658 D/WVCdm   (32198): [crypto_session.cpp(1108):Open]
  Lock: requested_security_level: Default

  A follow on CL will remove the manually added class/method information.

* Fix BoringSSL Compatibility of oec_session_util.cpp

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

  [ Merge of http://go/wvgerrit/37121 ]

  A previous change inadvertantly used APIs from OpenSSL that do not exist
  in BoringSSL in oec_session_util.cpp. As a temporary fix until we can
  move all targets to BoringSSL, this patch switches that file to use
  conditional compilation to choose the correct API depending on the
  library in use. It does not otherwise change the behavior of the file.

* Create local shared_ptr implementation

  [ Merge of http://go/wvgerrit/37600 ]

  Derived from protobuf version, which came from google3.
  Removed locking (not thread-safe) and removed weak pointers (not
  needed for usages in CDM).

  Locking can easily be added if needed.

* Revert C++11 usage - back to gnu++98

  Author: Gene Morgan <gmorgan@google.com>

  [ Merge of http://go/wvgerrit/37440 ]

  These changes roll back C++11-specific constructs:
    std::unique_ptr -> std::auto_ptr
    container initializers
    nullptr -> NULL
    std::shared_ptr to local shared_ptr
    compiler flags (-std=c++11 -> -sdt=gnu++98)

  NOTE: the "local" shared_ptr implementation is temporarily
  a direct reference to the shared_ptr implementation in
  third_party/protobuf. This has been fixed (implementation
  extracted and moved to core/include) in CL 37600.

* Make Android NDK Builds Work With Latest BoringSSL

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

  [ Merge of http://go/wvgerrit/37000 ]

  The latest updates to BoringSSL require C99 or later. Our NDK-based
  builds (OEMCrypto Variants & Fastball) were not specifying a C standard.
  This patch adds compiler flags so that C files are compiled as C11 now.
  Note that this is about the *C* standard in use, not the *C++* standard,
  which this patch leaves untouched.

*  Update BoringSSL to f7412cb072cc6b1847140e0c4f8b3ceeccd0e708

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

  [ Merge of http://go/wvgerrit/36761 ]

  This is the result of running UPDATE_BORINGSSL.sh. Future runs of this
  script should produce much smaller sets of changed files, but because
  the BoringSSL revision already in this directory was so old and
  contained many extraneous files from the Android operating system, the
  set of changed files is extensive this time.

* Refactoring the build files.

  [ Merge of http://go/wvgerrit/37041 ]

  Move all common build dependencies to .gypi so that all fuzz test

* Introduce service certificate request property

  Author: Rahul Frias <rfrias@google.com>

  [ Merge of http://go/wvgerrit/36941 ]

  Platforms differ on whether they allows service certificates to be
  requested if privacy mode is enabled and a certificate is not present.
  This property allows behavior to be configurable.

  Generating the service certificate request will be introduced
  in a follow on CL.

  BUG: 68328352

* 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.

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

* OEMCrypto_GenerateSignature API Fuzz Test.

  Author: Vasantha Rao Polipelli <vasanthap@google.com>

  [ Merge of http://go/wvgerrit/36863 ]

  - The first automated API fuzz test.

* Add Script to Update BoringSSL from Source

  [ Merge of http://go/wvgerrit/36760 ]

  Adds a script to third_party/boringssl/ that, when run, deletes all the
  auto-generated files in the generated/ directory and regenerates them
  from scratch, starting from the latest public HEAD of BoringSSL.

  Bug: 67907873

* Fix Fastball / OEMCrypto Variant BoringSSL Makefiles

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

  [ Merge of http://go/wvgerrit/36926 ]

  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.

  Bug: 67386164
  Test: build_android_mock.sh

* Add kit/ to BoringSSL Include Path for Fastball & OEMCrypto Variants

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

  [ Merge of http://go/wvgerrit/36925 ]

  When I moved the BoringSSL source in the tree, I updated the Android.mk
  files that pointed to it in order to build it. I did not realize that
  some makefiles outside that directory also contained hardcoded pointers
  into that directory. These references broke after the move. This patch
  fixes those paths to point to the new BoringSSL location.

* Separate Hand-Written BoringSSL Files from Downloaded/Generated Ones

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

  [ Merge of http://go/wvgerrit/36561 ]

  I want to make updating BoringSSL as simple as possible for us going
  forward. A future commit will add a script that automatically downloads
  and sets up the latest version of BoringSSL. To facilitate this script,
  a clear distinction needs to be made between the files that can be
  downloaded with / regenerated from the BoringSSL source and the files
  that are maintained by us by hand.

  The version of BoringSSL in this change is exactly the same as the one
  already in this directory. It has just been moved one folder deeper.

* Remove BoringSSL Symlinks, They Are Confusing Gerrit

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

  [ Merge of http://go/wvgerrit/36560 ]

  There are some symlinks in the current copy of BoringSSL that are
  causing headaches when I try to upload future changes to Gerrit. These
  were inherited from the Android OS and are not used by our build
  anywhere. They would be wiped out when I update BoringSSL anyway, but
  wiping them out in a separate change before I upload any other changes
  avoids confusing Gerrit.

* 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.

  Also tweaked some of the compiler settings for g++ support (revisit
  this later).

  This change resolves the all of the

  The license servers will return different keys and keyids.
  Sending the request to staging returned key ids and keys that were

  for all unit tests and removed the use of StrictMock from
  MockCryptoSession.

  Author: Jeff Fore <jfore@google.com>

  [ Merge of http://go/wvgerrit/35922 ]

  The handler for this was only set for one test and resulted
  in a number of failures.

* Set default handler for GetHdcpCapabilities. For
  now the default action is to call the real
  GetHdcpCapabilities of crypto_session.

  Author: Jeff Fore <jfore@google.com>

  [ Merge of http://go/wvgerrit/36140 ]

  I also changed the mock to a NiceMock to silence
  responses to unexpected calls to GetHdcpCapabilities.

  The default handler can be overridden as needed in
  the individual tests.

  [ Merge of http://go/wvgerrit/27921 ]

  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().

* Complete provisioning request/response for Provisioning 3.0

  Author: Gene Morgan <gmorgan@google.com>

  [ Merge of http://go/wvgerrit/27780 ]

  Fix bug on provisioning request path where GenerateDerivedKeys()
  was being called when preparing to generate the signature.

  Add message signature verification, and call correct OEMCrypto
  routine to rewrap the private key (OEMCrypto_RewrapDeviceRSAKey30).

* Implement Cdm::deleteAllUsageRecords()

  Author: Gene Morgan <gmorgan@google.com>

  [ Merge of http://go/wvgerrit/27780 ]

  Delete all usage records for current origin.  Removes usage
  records from file system and retains the PSTs.  The deletes
  any usage entries matching those PSTs held by OEMCrypto.

  [ Merge of http://go/wvgerrit/27585 ]

  We have a fork of the stringencoders library that we use for base64
  encoding.  This reimplements base64 encoding to remove the extra
  dependency and to reduce the amount of code.

  Author: Gene Morgan <gmorgan@google.com>

  [ Merge of http://go/wvgerrit/27605 ]

* Modifiable OEMCrypto

  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.

4d448d8165 Get System ID From OEM Cert
(This is a merge from http://go/wvgerrit/30220)

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.

457aceb859 Fixes metrics collection during CdmEngine close.
This fixes a problem where a CdmEngine instance (and its sessions) could
be closed before its metrics could be collected. The change allows the
wv_content_decryption_module to extract metrics from instances about to
be closed. These are held until reported to the caller.

Test: Manually verified that collection is now occurring correctly. Also
added unit test: wv_cdm_metric_test.

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.

ee5aff7706 Correct setting of service certificate.
[ Merge of http://go/wvgerrit/23380 ]

The service certificate was setup correctly if specified in mediadrm
properties. If instead the service certificate was later fetched from
the license service, it would not be marked as valid. This led to an
infinite loop of service certificate fetches and processing. This
prevented the license from being fetched and playback failures.

  [ Merge of http://go/wvgerrit/15544 ]

  Patch courtesy of Spotify.

* Changing vague BufferReader log message

  [ Merge of http://go/wvgerrit/15515 ]

  Amending the buffer reader log message for null parameters in the
  read function to say the type of parameter to help tell the
  difference between Read2, Read2s, Read4, Read4s, Read8, and
  Read8s.

* Fix HTTP socket tests

  [ Merge of http://go/wvgerrit/15521 ]

  This fixes the build on Jenkins. I missed these when I updated HTTP
  socket because they are not part of the CE CDM test suite.

* Update HttpSocket for IPv6

  [ Merge of http://go/wvgerrit/15517 ]

  Previously, HttpSocket made assumptions about IPv4.
  This CL updates this utility to be agnostic to IPv4 vs IPv6.
  If our servers start resolving to IPv6 addresses in future,
  our tests can now handle this transparently.

cdf309b9f4 Reject session clobbering and namespace fixes
* 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.

* Move timer and timer_unittest to Android.

4252a4b790 Make PSSH parser more robust.
(This is a merge of http://go/wvgerrit/12700 from the Widevine CDM
repository.)

Adds unit tests which cover several cases, including five which are
fixed in this patch:

* Find a Widevine PSSH after a PSSH with non-zero flags.
  (We have no control over another provider's abuse of the flags field,
   so we should not give up if such a PSSH appears before ours.)
* Find a Widevine PSSH after a v1 PSSH.
  (CENC now specifies a general v1 format.  We don't have to support it
   directly in the CDM, but we do have to skip it gracefully.)
* Find a Widevine PSSH after a non-PSSH box.
  (This would be unusual input, but we can easily recover from it.)
* Parse a PSSH box with a size field of 0, which means "the rest of the
  buffer."
  (This would be unusual input, too, but is technically allowed for any
   MP4 box.)
* Parse a v1 Widevine PSSH box, ignoring the new fields we don't need.

  if decryption takes place.
* Usage reports now get deleted on an unprovision request.
* Policy timer is now started when offline licenses are restored.
* Usage session is now released, when a usage response is received.
* Usage tests ahev been enabled.
* Added CDM extended duration (integration) tests to test usage reporting
  and querying. These need to be run manually as they take a while (currently
  half an hour).
