Current version of openssl we are using is 01.01.00g.
We have tested and able to reproduce this issue with the OPENSSL 01.00.02k
version that is packaged with RHEL 7.4 as well.

Openssl version used is 01.01.00g. I am also attaching the latest pcap file
for your reference.

Hi All,
We have application that provide DTLS security for SCTP connections. During
our testing we found that API "*SSL_connect* " fail and always returns
SSL_ERROR_WANT_READ which causes infinite loop in the application.

I have query regarding the SSL_read on blocking socket. How to come out of

As per the documentation SSL_read will only return if there is any data or
an error occurred.

We are using openssl for providing the secured communication for our

Does the openssl disconnects the existing connection?

Hi,
We are using Openssl for establish a secure communications for both
TCP/SCTP connections.
In our application it is possible that remote end forcefully disconnect the
connection due to which
SSL_Write raises a SIGPIPE which we want to suppress. Does openssl
provide any way to set MSG_NOSIGNA
(at least I am assuming this is the same issue):

Hi,
We are running SCTP connections with DTLS enabled in our application. We
have adapted openssl version (openssl-1.1.0e) to achieve the same.
We have generated the self signed root and node certificates for testing.
We have a strange problem with the incomplete DTLS handshake if we run the
DTLS
support.

Hi,
We have a client, server applications that is using SCTP as a transport
protocol. We have to secure the connections using DTLS. I am using openssl
version 1.0.2 which supports DTLS. But the problem i am facing is usage of
DTLS SCTP related API's. Openssl documentation does not clearly explain
