This patch adds a suite of tests for OEMCrypto that verifying buffer
overflow and off-by-one errors. The reference code has also been
updated to pass these tests.
The ODK library and the OEMCrypto API have not changed since the
release of version 16.4.
This commit has the initial ODK library. Partners may use this code
to begin integrating the ODK library into their platform. The
functionality is not complete, but this should help partners get an
early start playing with build files.
This change updates the unit tests to have more comments so that it is
more clear what went wrong if a test fails.
Also, some utility code has been changed to make it easier to support
new platforms and read/write locks.
Also, the reference code has had some refactoring added to make it
easier for Widevine to test CDM code. There should be no
functionality differences in the reference code.
Also, in the main API doc, there was an obsolete paragraph in the
description of the threading model. This paragraph has been removed.
This CL updates has several changes.
The document WidevineModularDRMSecurityIntegrationGuideforCENC_v14.pdf
had an incorrect definition of the PST_Report structure. The header
file had the correct definition. This has been updated and the version
number of the document was rolled to 14.1
The unit tests TwoHundredEntries has been modifed to make sure that if
the usage table is full, then OEMCrypto will return the error
OEMCrypto_ERROR_INSUFFICIENT_RESOURCES. This is important for the CDM
layer to correctly delete old licenses and secure stops when this
happens.
Several other unit tests covering corner cases have been added.
The reference code has been cleaned up a bit. Some logging that might
be dangerous has been removed.
This renames the "mock" code to "reference" because that's really what
it is. Also, some code has been moved from the CDM repo to a common
utility directory so that it can be included here, and the oemcrypto
unit tests can now be built without having access to a current CDM
repo.
There are no functionality changes in this CL.
