The _public_ key info is temporarily stored (`client.userPrivateKey`). + - **Password Auth:** + - If _no_ public key was offered, the client sends username/password. + - Proxy queries the `Database` (`db.findUser(ctx.username)`). + - If user exists, proxy compares the hash (`bcrypt.compare(ctx.password, user.password)`). + - If valid, auth succeeds (`ctx.accept()`). + - **Failure:** If any auth step fails, the connection is rejected (`ctx.reject()`). + +3. **Session Ready & Command Execution:** + - Client signals readiness (`client.on('ready', ...)`). + - Client requests a session (`client.on('session', ...)`). + - Client executes a command (`session.on('exec', ...)`), typically `git-upload-pack` or `git-receive-pack`. + - Proxy extracts the repository path from the command. + +4. **Internal Processing (Chain):** + - The proxy constructs a simulated request object (`req`). + - It calls `chain.executeChain(req)` to apply internal rules/checks. + - **Blocked/Error:** If the chain returns an error or blocks the action, an error message is sent directly back to the client (`stream.write(...)`, `stream.end()`), and the flow stops. + +5. **Connect to Remote Git Server:** + - If the chain allows, the proxy initiates a _new_ SSH connection (`remoteGitSsh = new Client()`) to the actual remote Git server (e.g., GitHub), using the URL from `config.getProxyUrl()`. + - **Key Selection:** + - It initially intends to use the key from `client.userPrivateKey` (captured during client auth). + - **Crucially:** Since `client.userPrivateKey` only contains the _public_ key details, the proxy cannot use it to authenticate _outbound_. + - It **defaults** to using the **proxy's own private host key** (`config.getSSHConfig().hostKey.privateKeyPath`) for the connection to the remote server. + - **Connection Options:** Sets host, port, username (`git`), timeouts, keepalives, and the selected private key. + +6. **Remote Command Execution & Data Piping:** + - Once connected to the remote server (`remoteGitSsh.on('ready', ...)`), the proxy executes the _original_ Git command (`remoteGitSsh.exec(command, ...)`). + - The core proxying begins: + - Data from **Client -> Proxy** (`stream.on('data', ...)`): Forwarded to **Proxy -> Remote** (`remoteStream.write(data)`). + - Data from **Remote -> Proxy** (`remoteStream.on('data', ...)`): Forwarded to **Proxy -> Client** (`stream.write(data)`). + +7. **Error Handling & Fallback (Remote Connection):** + - If the initial connection attempt to the remote fails with an authentication error (`remoteGitSsh.on('error', ...)` message includes `All configured authentication methods failed`), _and_ it was attempting to use the (incorrectly identified) client key, it will explicitly **retry** the connection using the **proxy's private key**. + - This retry logic handles the case where the initial key selection might have been ambiguous, ensuring it falls back to the guaranteed working key (the proxy's own). + - If the retry also fails, or if the error was different, the error is sent to the client (`stream.write(err.toString())`, `stream.end()`). + +8. **Stream Management & Teardown:** + - Handles `close`, `end`, `error`, and `exit` events for both client (`stream`) and remote (`remoteStream`) streams. + - Manages keepalives and timeouts for both connections. + - When the client finishes sending data (`stream.on('end', ...)`), the proxy closes the connection to the remote server (`remoteGitSsh.end()`) after a brief delay. + +### Data Flow Diagram (Sequence) + +```mermaid +sequenceDiagram + participant C as Client (Git) + participant P as Proxy Server (SSHServer) + participant DB as Database + participant R as Remote Git Server (e.g., GitHub) + + C->>P: SSH Connect + P-->>C: Request Authentication + C->>P: Send Auth (PublicKey / Password) + + alt Public Key Auth + P->>DB: Verify Public Key (findUserBySSHKey) + DB-->>P: User Found / Not Found + else Password Auth + P->>DB: Verify User/Password (findUser + bcrypt) + DB-->>P: Valid / Invalid + end + + alt Authentication Successful + P-->>C: Authentication Accepted + C->>P: Execute Git Command (e.g., git-upload-pack repo) + + P->>P: Execute Internal Chain (Check rules) + alt Chain Blocked/Error + P-->>C: Error Message + Note right of P: End Flow + else Chain Passed + P->>R: SSH Connect (using Proxy's Private Key) + R-->>P: Connection Ready + P->>R: Execute Git Command + + loop Data Transfer (Proxying) + C->>P: Git Data Packet (Client Stream) + P->>R: Forward Git Data Packet (Remote Stream) + R->>P: Git Data Packet (Remote Stream) + P->>C: Forward Git Data Packet (Client Stream) + end + + C->>P: End Client Stream + P->>R: End Remote Connection (after delay) + P-->>C: End Client Stream + R-->>P: Remote Connection Closed + C->>P: Close Client Connection + end + else Authentication Failed + P-->>C: Authentication Rejected + Note right of P: End Flow + end + +``` + +``` + +``` diff --git a/config.schema.json b/config.schema.json index dafb93c3f..b8af43ecf 100644 --- a/config.schema.json +++ b/config.schema.json @@ -7,7 +7,7 @@ "properties": { "proxyUrl": { "type": "string", -
