The previous code fixed a backwards compatibility error for v18 provisioning requests being parsed by a v17 or older server. This bumped the minor version number to v18.1. v17 servers are still expected to fail when trying to parse v18.0 provisioning requests, and v18.1 requests will pass. However, it did not correctly account for existing v18.0 requests on v18.1+ servers. v18.0 messages were naively detected by a failure to parse, and the parse function was not run again. This left the resulting nonce and session_id values uninitialized. This CL fixes that by explicitly handling the v18.0 and v18.1+ cases, ensuring that the parse function succeeds and all relevant information is copied over. Furthermore, the unit test that was meant to catch this edge case has been improved to validate the resulting parsed message. All code changes affect the server. This does not affect the client code eg OEMCrypto PiperOrigin-RevId: 523714529 Merged from https://widevine-internal-review.googlesource.com/170110 Change-Id: I21911c4bb4304de2d93f092f356402bbd4240874
This ODK Library is used to generate and parse core OEMCrypto messages for OEMCrypto v16 and above. This library is used by both OEMCrypto on a device and by Widevine license and provisioning servers. The source of truth for these files is in the server code base on piper. Do not edit these files in the Android directory tree or in the Widevine Git repository. If you need to edit these files and are not sure how to procede, please ask for help from an engineer on the Widevine server or device teams.
