DTLS bug in mbedTLS 3.6.4?

Hello sir,

Please help check if it’s a bug in the mbedTLS 3.6.4 for DTLS handshaking.

When I using cookie to build handshake with the clients in DTLS, the handshake would be terminated once the “server_hello_verify_request“ was sent. Seems it’s return a wrong number in the server handshake code.

BR,

J.W

Seems this is intended. Maybe it’s my fault.

Anyway, I added a patch in the application layer, it can move on till the last decryption of the handshake message.
