70ffdb1c6a Backwards Compatibility Tests
Merge from Widevine repo of http://go/wvgerrit/24241

The CL also only modifies existing tests so that they will pass
with an old version of OEMCrypto, or it filters out the tests so
that they do not run.  This positions us so that we can more
easily verify how much backwards compatibility we expect to work.

4025322185 Source and destination buffers may point to same buffer
Merge from Widevine repo of http://go/wvgerrit/23581

This CL adds some unit tests to oemcrypto to verify that DecryptCENC
and the generic encrypt and decrypt functions behave correctly when
the input and output buffer is the same. i.e. decrypt in place.

The mock and haystack are also updated to pass the tests.

7112a5eec3 Add more slack to timing tests
Merge from Widevine repo of http://go/wvgerrit/24042

This CL adjusts the tolerance in tests that check the license_received
time.  This was periodically failing because a nonce flood might delay
the test by 1 second, which was being rounded up to 2.  The tolerance
is now 3.  The time is explicily used when it is available.  Some
extra logging is also added to the mock.

eade07c7a9 Minor build updates
This CL removes some unused variables, and changes some integers to
unsigned integers.  On some platforms, we were getting compiler errors
and unit test failures.

3d977d999c Reference Code for Big Usage Tables
Merge from widevine of http://go/wvgerrit/23283

This CL adds some big usage table functionality to the oemcrypto
mock and unit tests.

Still missing are: backwards compatibility, defragging the table,
haystack code, and lots of new unit tests.

The haystack now reports it doesn't support usage tables, so that
the unit tests will pass.  This will be fixed in a future CL.

7152957e42 Replace PST Report with buffer
Merge from Widevine repo of http://go/wvgerrit/23044

On some platforms, the compiler will not pack structures.  This CL
replaces the OECrypto_PST_Report packed structure with a simple buffer
of uint8_t.  This changes the signature of OEMCrypto_ReportUsage as
part of OEMCrypto v13.

There is also a new wrapper class that test code, the mock, and debug
code can use to access data in the report.

The old packed structure definition is moved to the level 3, where we
use a compiler that packs sructs when asked nicely.

3e525dfdd3 OEMCrypto rewrap rsa key 3.0 unit tests

053ff5bd3c OEMCrypto Tests Provisioning Method
Merge from widevine repo of http://go/wvgerrit/21682

This CL updates oemcrypto/test/oec_device_features.cpp to figure out
the provisioning method and filter out tests that are not relevant to
the device's method.

This CL also introduces unit tests for GetOEMPublicCertificate.

Unit tests for RewrapDeviceRSAKey30 will be in a future CL.

0fb76d5c1b Refactor OEMCrypto Unit Tests
Merge from widevine repo of http://go/wvgerrit/21681

This CL refactors some oemcrypto unit tests in preparation for adding
Provisioning 3.0 tests.

- The signature GenerateNonce has changed.  Instead of the caller
  passing in a pointer for the nonce, we store the nonce in a member
  variable of Session.

- GenerateDerivedKeys is being replaced by InstallTestSessionKeys.
  This sets up and calls the appropriate derive keys method.  This
  function is in the test class, instead of the session class so that
  multiple sessions in a class can share the same wrapped rsa key.
  This will be modified for provisioning 3.0 in a future CL.

- Rename tests that require a keybox.  Some tests are specific for
  using a keybox to request a DRM cert. These tests are renamed so we
  can filter them out on devices that use an OEM Cert.  Corresponding
  tests for devices using provisioning 3.0 will be in a future CL.

- Some member variables and methods in the class Session were not
  used.  They are removed.

- Added openssl smart pointer.

- Comments.  I added comments.

- clang format.

a200710d53 Add unit test to verify signature
Merge from widevine repo of http://go/wvgerrit/21521

On devices that use provisioning 3.0, the function
OEMCrypto_GenerateSignature will only be used for a license renewal.
This CL adds a call to OEMCrypto_GenerateSignature to the refresh key
tests.  Otherwise, there would be no coverage at all for that
function.

67b06a70e4 Buffer Size Unit Tests
Merge from widevine repo of http://go/wvgerrit/21260

This CL adds some oemcrypto unit tests for various buffer sizes, as
described in b/28887904 and the OEMCrypto v12 specification.

Encryption and Decryption buffers can be 100k large.  License request
and response messages can be 8k. A provider session token (pst) can be
at most 255 bytes long.

I also passed the code through clang-format.

f0cee3ad20 Require 20 keys per session and 10 sessions
Merge from widevine repo of http://go/wvgerrit/20981

OMECrypto v12 requires at least 20 keys per session and at least 10
sessions.  This CL updates the unit tests to verify this, and updates
level 3 and mock code to conform.

This CL also updates the level 3 oemcrypto to support 16 sessions and
320 keys total.

626a416e5f Extract Session class from oemcrypto_test.

tests in other modules.  For example, keys can be added for testing
encryption and decryption operations in CDM-level tests.
