mbedTLS handshake issue

[pmeskoni]

When using MbedTLS, the handshake failed with a -76 error or sometimes a -75 error during the callbacks to mg_net_send() and mg_net_recv(). I believe this is because the logic to determine if Mongoose "should block" is not right.

in Mongoose 7.6 tls_mbed.c:

 static bool mg_wouldblock(int n) {
       return n < 0 &&
                  (errno == EINPROGRESS || errno == EAGAIN || errno == EWOULDBLOCK);
 }

We changed to this:

 static bool mg_wouldblock(int n) {
       return n < 0 &&
                  mg_sock_would_block();
 }

Has anyone else seen this issue?

Thanks,
PM
