Build # 29655430433

Build Type

Pull #208

github

Committed by rm-hull

Commit Message

fix: merge EDNS0 options instead of appending

Ensures that multiple EDNS0 options from upstream responses are
correctly merged into the existing OPT record in the response,
preventing duplicate OPT records which violate DNS protocol
specifications.

```mermaid
sequenceDiagram
    participant U as Upstream
    participant D as Dispatcher
    participant C as Client

    U->>D: Return DNS message with extra RR (OPT)
    D->>D: Check if OPT exists in response
    alt OPT exists
        D->>D: Merge options into existing record
    else No OPT
        D->>D: Append OPT record
    end
    D->>C: Send valid DNS response
```
