Hello,

In our project we use mbedTLS together with freeRTOS. mbedTLS requires an mbedtls_ssl_context (let's say `ssl_context`) for the send (`mbedtls_ssl_write(...)`) and receive (`mbedtls_ssl_read(...)`) functions. In our project we have a freeRTOS task `A` to send data with mbedTLS and a freeRTOS task `B`to receive data with mbedTLS over the same session/interface. Both tasks use the same `ssl_context` instance. Potentially sending and receiving can happen at the same time.

Is it safe to use the same `ssl_context` instance from both taks? Or should only one task access the `ssl_context`?

At the moment we are using `mbedtls_ssl_read(...)` in blocking mode and hence the `ssl_context` cannot be protected against multiple access with a mutex because then the sending task cannot obtain the mutex as long as the receiving task is the blocked receiving state (holding the mutext).

Thank you for your help.

Best regards, Pascal
