# TSVConnReenable(3ts)

TSVConnReenable API function

## NAME

TSVConnReenable - TSVConnReenable API function

## TSVCONNREENABLE

### Synopsis

```
#include <ts/ts.h>
```

- **void TSVConnReenable(*TSVConn* svc)**

  ### Description

Re-enable the SSL connection *svc*. If a plugin hook is called, ATS processing on that connection will not resume until this is invoked for that connection.

If the server is running OpenSSL 1.0.2, the plugin writer can pause SSL handshake processing at the certificate callback  by not reenabling the connection. Running an OpenSSL versions older than 1.0.2, the handshake processing in **SSL\_accept** will not be stopped even if the SNI callback does not re-enable the connection.

Additional processing could re-enable the virtual connection causing the **SSL\_accept** to be called again to complete the handshake exchange.  In the case of a blind tunnel conversion, the SSL handshake will never be completed by Traffic Server.

This call does appropriate locking and scheduling, so it is safe to call from another thread.

## TSVCONNREENABLEEX

### Synopsis

*#include \<ts/ts.h\>*

- **void TSVConnReenableEx(*TSVConn* svc, *TSEvent* event)**

  ### Description

An extended version of TSVConnEnable that allows the plugin to return a status to the core logic.  If all goes well this is TS\_EVENT\_CONTINUE.  However, if the plugin wants to stop the processing it can set the event to TS\_EVENT\_ERROR.

For example, in the case of the TS\_SSL\_VERIFY\_SERVER\_HOOK, the plugin make decide the origin certificate is bad.  By calling TSVonnReenable with TS\_EVENT\_ERROR, the certificate check will error and the TLS handshake will fail.
