A minimal set of changes to make the LWIP mbedtls app compatible with the latest mbedTLS 3.6.x branch. Only TLS 1.2 with LWIP http client app, and OS_SYS=0 (U-Boot) have been tested. More changes might be required in other setup combinations. Signed-off-by: Javier Tia <javier.tia@linaro.org>
When using the http-client LWIP app in U-Boot (OS_SYS=0), the handshake fails because LWIP doesn't send TCP packets after it initiates. Signed-off-by: Javier Tia <javier.tia@linaro.org>
SNI, or Server Name Indication, is an addition to the TLS encryption protocol that enables a client device to specify the domain name it is trying to reach in the first step of the TLS handshake, preventing common name mismatch errors and not reaching to HTTPS server that enforce this condition.
