Known Issues

DTS2024011209743

[Secure storage tests] In the first dataset test of 64 KB reads and writes, the performance result does not meet the requirement. The fluctuation rate of all data blocks is higher than 20%. In the second test, the fluctuation rate is higher than 20% with 700 KB data.

Minor

1. The confidential OS applies to Java, Python, and Rust applications. They are not TAs or CAs and do not involve secure storage, and are free from this problem.

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 problem is caused by the customer's demo. No mitigation or workaround measures are needed.

2. Confidential OS 24.0.RC1 is released only to specific customers. Locate and resolve this problem when integrating with the customer's system.

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

Confidential OS 24.0.RC1 is released only to specific customers. This problem is caused by the customer's demo. The customer agrees that this problem can be kept in the current version. During subsequent integration and joint commissioning, the customer and Huawei will jointly locate and resolve this problem, which will not affect commercial integration and rollout.

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 pays major attention to the concurrent query performance, whereas the preprocessing performance is not included in the raw requirements. We have communicated with the customer that the POC version provided at the end of February has met the customer's function and performance requirements. We will check whether to resolve this issue at later 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.
