X-BeenThere: dev@dpdk.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: DPDK patches and discussions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: dev-bounces@dpdk.org Sender: "dev" PMD did not remove tunnel offload object from tunnels database before it released the object memory. As the result, the tunnels database become corrupted and subsequent search operations triggered PMD crash. The patch removes tunnel offload object from the tunnels database when the object is not in-use by PMD any more.
