Known Issues

DTS2024011209743

[Secure storage tests] In the first round of testing, the 64 KB read/write performance failed to meet the benchmark, with the fluctuation rate of all blocks exceeding 20%. In the second test, the fluctuation rate is higher than 20% with 700 KB data.

Minor

1. High-level language applications in the confidential OS environment include Java, Python, and Rust applications. Because they are non-TA/CA applications and do not involve secure storage, they are unaffected by this issue.

2. In hardware security machine (HSM) scenarios, applications are TAs or CAs, and they call read and write APIs for secure storage. These applications are affected by this problem. The 23.0.0 TR6 version is recommended for such scenarios. Add this note in the RC1 Release Notes.

This issue will be resolved in the commercial release of June 30, 2024.

The customer's Rust services are not affected.

Run a Java test demo for 7x24 hours. After the demo has been executed for 2663 consecutive times, the -r command is suspended but no exception log is generated.

Minor

Avoid loading and running Java applications in the confidential OS.

This issue will be resolved in the commercial release of June 30, 2024.

The customer's Rust services are not affected.

The customer has 3 nodes and 3 servers. The REE client initiates 3 preprocessing tasks (with 30 million data records). During the preprocessing, one server crashes.

Minor

1. This is an issue specific to the customer's demo; therefore, no mitigation or workaround is required.

2. Confidential OS 24.0.RC1 is released only to specific customers. It has been agreed upon that we will assist the customer in locating and resolving this issue during system integration.

This issue will be resolved in the commercial release of June 30, 2024.

Confidential OS 24.0.RC1 is released only to specific customers. Root cause analysis indicates that this is an issue specific to the customer's demo. It has been agreed upon with the customer that this issue will be deferred in the current version; both parties will jointly troubleshoot and resolve it during subsequent integration and joint commissioning. This does not affect commercial integration or the official launch.

DTS2024020203194

In the customer's Rust Demo, the I/O speed in the TEE is too slow. It takes 9 minutes to preprocess 1 million data records, but it takes no more than 20 seconds to preprocess data records in the REE.

Minor

The customer is primarily focused on concurrent query performance, while preprocessing performance was not part of the originally agreed requirements. We have communicated with the customer, and they confirmed that the POC version delivered at the end of February already meets their current functional and performance needs. Whether further performance optimization is required will be reviewed in subsequent phases of the project.

This issue will be resolved in the commercial release of June 30, 2024.

Only the preprocessing phase of the Rust query service is affected. The customer focuses mainly on the query performance. Therefore, the impact is small.
