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 updates the version compatibility document to clarify how the
Android hidl interface works.
- Testing of analog output was removed because the unit tests cannot
verify correct behaviour.
- Some buffer overflow tests have been added.
This CL updates the following:
- Some robustness improvements to the ODK library.
- Unit tests assume that license release does not have a core message.
- Added version string to unit tests.
The version string of the unit tests is now:
OEMCrypto unit tests for API 16.2. Tests last updated 2020-03-27
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.
