Hi,
OpenSSL version 1.1.1 FIPS, on Fedora 29
(on both client and server)
I'm seeing a client not receiving, or ignoring, what
should be a fatal alert from the server during handshake.
The server is requiring a client-certificate, via:
SSL_CTX_set_verify(sctx,
SSL_VERIFY_PEER | SSL_VERIFY_FAIL_IF_NO_PEER_CERT, ...)
...
server_ssl = SSL_new(server_ctx)
...
SSL_accept(server_ssl)
... and the client is not supplying one. This is a deliberate
testcase. The server debug output goes:

So far so good. The client however sees:

The code running up to that last line indicates that
SSL_connect() returned without error:
----
rc = SSL_connect (*ssl);
alarm(0);
if (sigalrm_seen)
{
printf("SSL_connect timed out\n");
return 0;
}
if (rc <= 0)
{
ERR_print_errors_fp(stdout);
return 0;
}
printf("SSL connection using %s\n", SSL_get_cipher (*ssl));
----
What am I doing wrong?
