ERROR_IPSEC_WRONG_SA - 13912 (0x3658)

Technical Meaning

The ERROR_IPSEC_WRONG_SA error indicates that a packet was received on an IPsec Security Association (SA) that does not match the characteristics of the incoming packet. This typically occurs when the security parameters or attributes associated with the SA do not align with those expected by the system.

Error Details

This error is specific to the IPsec protocol, which provides secure communication over networks using cryptographic techniques. When a packet arrives, the system checks if it matches the current SA. If there is a mismatch in any of the security parameters (such as encryption algorithm, key, or lifetime), this error is generated.

Usage Context

This error can occur during various IPsec operations, such as when establishing or maintaining secure communication channels between hosts. It may also be encountered when troubleshooting issues related to packet processing and security associations.

Developer Interpretation

Developers should interpret this error as an indication that the incoming packet does not conform to the expected security parameters of the current SA. This could be due to a variety of reasons, such as incorrect configuration, expired SAs, or mismatches in cryptographic settings.

Related Errors

• ERROR_IPSEC_SA_RENOWN (0x3659): Occurs when an SA is renewed but the packet does not match the new parameters.
• ERROR_IPSEC_PROCESSING_FAILURE (0x364F): Indicates a failure in processing the packet, which may include errors like ERROR_IPSEC_WRONG_SA.

FAQ

Q: What causes this error?

A: This error typically occurs when there is a mismatch between the security parameters of the incoming packet and the current SA. Common causes include incorrect configuration or expired SAs.

Q: How can I resolve this issue?

A: Review the IPsec configuration, ensure that SAs are properly established and renewed, and verify that all cryptographic settings match those expected by the system.

Summary

The ERROR_IPSEC_WRONG_SA error is a specific technical issue related to IPsec packet processing. It indicates a mismatch between the security parameters of an incoming packet and the current SA. Developers should focus on ensuring proper configuration and maintenance of SAs to avoid this error.
