7992650ff6 Add "Model Year" to list of CDM identification properties
(This is a merge of http://go/wvgerrit/138969.)

Provisioning 4.0 on CE CDM requires not only the make & model but the
model year in order to relate a device back to its system ID. This patch
adds model year to the list of properties that partners must provide as
client identification.

As no equivalent field exists for Android, this property is not
provided on Android platforms.

3acc64a478 Added an OTA keybox provisioner.
[ Merge of http://go/wvgerrit/133729 ]
[ Cherry pick of http://ag/15836224 ]

The OtaKeyboxProvisioner is a system-wide provisioner for sharing the

Added keybox provisioning proto fields.

[ Merge of http://go/wvgerrit/133730 and http://go/ag/15113032 ]

This CL copies over the required license_protocol.proto changes that
are required for OTA keybox provisioning.  These fields are defined in
the server-side certificate_provisioning.proto, defined in
http://cl/377533774.

Note, changes are slightly different from server proto due to the RVC
version of license_protocol.proto being out of date with SC and newer
changes.

Added OTA keybox provisioning device files.

[ Merge of http://go/wvgerrit/133743 and http://go/ag/15421141 ]

This change adds a new set of proto messages/fields the CDM's device
files for recording device and engine information around OTA keybox
provisioning (OKP).

To make cleanup and thread protection possible, there is a single file
which will contain all the information for the device as a whole and
each CDM engine tied to an app/origin.

ca335b2c11 Only one function for reporting usage support.
[ Merge of http://go/wvgerrit/121567 ]

Replaced the two usage support functions GetUsageSupportType() and
UsageInformationSupport() into a single function HasUsageInfoSupport().

Since moving to only supporting a single usage info system (usage table
header + usage entries), the different usage support functions have
lost their purpose.

One version of the method works on an open session and will use a
cached value of the property if previously set.  The other can be
called without opening the session (as used for query calls).

This is part of larger fix for the usage table initialization process.

78f4bca3a9 Restrict reserved Client ID fields.
[ Merge of http://go/wvgerrit/108904 ]

Client ID name-value fields in the license request share the same
namespace with app parameters and WV standard device information.  As
a result, it was possible for applications to provide parameters that
could potentially fool the license server with spoof values.

This CL restricts the use of the fields that are common across both the
Android CDM and CE CDM.  Currently, Android specific fields are
restricted by the MediaDrmPlugin layer, and there are no CE CDM
specific fields currently defined.

The non-HIDL DRM plugin does not restrict these fields; however, it
will be removed in S.

Types of cleanup:
  - Removed function / class prefixes from the logs.
  - Fixed log string format options to match the types passed
  - Corrected small spelling mistakes / typos
  - _Tried_ to make the log format more consistent
  - Added static_cast<int> conversion on enumerations when logged
  - Changed several LOGE to LOGW and vice versa
      - Used LOGE if the triggering condition stops the method/function
        from completing its task
      - Used LOGW if the triggering condition changes the expected
        outcome but does not stop the rest of the method/function's
        task
  - Changed several instances of `NULL` to `nullptr`
  - Ran clang-format on files after cleanup

5ea429ee2b Don't Use StringStream When It's Overkill
(This is a merge of http://go/wvgerrit/76063)

Now that we have C++11, many places that do string formatting or parsing
can be replaced with std::to_string() or one of the std::sto*() family
of functions. This patch updates places that do simple stringifying or
parsing to use these functions. Some parts of the code are left
untouched because they were using StringStream to do more complex
actions, such as constructing more complex output or checking the status
of the parsing.

aac1439dea Merges to android Pi release (part 12)
These are a set of CLs merged from the wv cdm repo to the android repo.

* Correct error logging

  Author: Rahul Frias <rfrias@google.com>

  [ Merge of http://go/wvgerrit/40000 ]

  In tests, we set the cipher list to avoid using insecure
  ciphers when connecting to the provisioning/license service.
  The result of setting the cipher list was being incorrectly
  validated.

* Move mips cache headers to clear_cache_function.h

  Author: Srujan Gaddam <srujzs@google.com>

  [ Merge of http://go/wvgerrit/39700 ]

  Since the clear_cache function has been moved away from the dynamic
  adapter, we need these conditional includes to be migrated as well for
  MIPS.

* Comment out Level 3 debug call until merge

  Author: Srujan Gaddam <srujzs@google.com>

  [ Merge of http://go/wvgerrit/39761 ]

  This call was introduced in go/wvgerrit/34260/. Since the haystack tool
  in google3 still needs this merge, this should be commented out so the
  tool can still build until the merge has finished.

  As part of b/70523618, this CL moves interfaces that partners are
  responsible for in Level 3 to level3.h so they can be visible as
  part of the CDM release process. It also cleans up some of the
  names of the files and adds documentation.

  [ Merge of http://go/wvgerrit/39505 ]

  From the android K release onwards certificates were stored in
  security level specific directories. If upgrading from
  previous releases persistent information needed to be moved
  to those directories.

  Since no device is likely to upgrade from J to Pi, comptibility
  support can be removed.

  [ 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.

* Modified RNG for Level3 to use more entropy

  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.

  old versions of oemcrypto from the dedicated branches oemcrypto-v*,
  which [will eventually] contain old oemcrypto versions, that build

  The code has been restructured to allow encryption of client
  identification in provisioning requests. This will be enabled
  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.
