Various code-cleanups. Use SSL_CTX_set_mode(ctx, SSL_MODE_AUTO_RETRY) insead of handling SSL_ERROR_WANT_READ everywhere. Turn off the linger option on connected sockets to avoid failure. Add BIO_set_conn_mode(conn, BIO_SOCK_NODELAY) to improve thruput. Continue test even without -cipher option as in 1.0.2. Reviewed-by:

For DTLS/SCTP we were waiting for a dry event during the call to tls_finish_handshake(). This function just tidies up various internal things, and after it completes the handshake is over. I can find no good reason for waiting for a dry event here, and nothing in RFC6083 suggests to me that we should need to. More importantly though it seems to be wrong. It is perfectly possible for a peer to send app data/alerts/new handshake while we are still cleaning up our handshake. If this happens then we will never get the dry event and so we cannot continue.

At a couple of points in a DTLS/SCTP handshake we need to wait for a dry event before continuing. However if an alert has been sent by the peer then we will never receive that dry event and an infinite loop results. This commit changes things so that we attempt to read a message if we are waiting for a dry event but haven't got one yet. This should never succeed, but any alerts will be processed.

The sid_ctx is something of a "certificate request context" or a "session ID context" -- something from the application that gives extra indication of what sort of thing this session is/was for/from. Without a sid_ctx, we only know that there is a session that we issued, but it could have come from a number of things, especially with an external (shared) session cache. Accordingly, when resuming, we will hard-error the handshake when presented with a session with zero-length sid_ctx and SSL_VERIFY_PEER is set -- we simply have no information about the peer to verify, so the verification must fail. In order to prevent these future handshake failures, proactively decline to add the problematic sessions to the session cache. Reviewed-by:

We did the SSL_CONF_cmd() pass last of all things that could affect the SSL ctx. However, the results of this, for example: -max_protocol TLSv1.3 -tls1_2 ... would mean that the protocol min got set to TLSv1.2 and the protocol max to TLSv1.3, when they should clearly both be TLSv1.2. However, if we see the SSL_CONF_cmd() switches as generic and those internal to s_client and s_server as specialisations, we get something that makes a little more sense.

Commit 87e8feca (16 years ago!) introduced a bug where if we are attempting to insert a cert with a duplicate subject name, and duplicate subject names are not allowed (which is the default), then we get an unhelpful error message back (error number 2). Prior to that commit we got a helpful error message which displayed details of the conflicting entry in the database. That commit was itself attempting to fix a bug with the noemailDN option where we were setting the subject field in the database too early (before extensions had made any amendments to it). This PR moves the check for a conflicting Subject name until after all changes to the Subject have been made by extensions etc. This also, co-incidentally fixes the ca crashing bug described in issue 5109.

There are things depending on configdata.pm. However, it's perfectly possible that there is one in the source directory from a previous build, and that might disrupt an out of source build. To avoid this conflict, make sure never to use the source tree configdata.pm in that case, i.e. make the hard assumption that it's a generated file in the build tree, which it is. Reviewed-by:
