I use LwIP on STM32 MCU. I have a working combination of LwIP + MbedTLS +
MQTT. I found a possible memory leak in function
altcp_tls_create_config_client_2wayauth. Inside the function
mbedtls_ssl_conf_own_cert there is line:

new_cert = mbedtls_calloc( 1, sizeof( mbedtls_ssl_key_cert ) );

which allocates new memory. This memory is never released. When I added line:


to the altcp_tls_free_config function, the memory leak is gone.
