We see the same problem with DTLS over SCTP. In our application, there are messages as large as 60K, so we are interested in knowing if there is a way to send them over DTLS.

Previously in its SSL_CTX I set the SSL_MODE_ENABLE_PARTIAL_WRITE option to enable SSL_write() to return less than the given data length. It does not work. I call SSL_write() by passing a very long data (65536) and it still returns -1. So, in case I want to write a big data over a DTLS UDP connection, how can I do that? I expected that SSL_MODE_ENABLE_PARTIAL_WRITE would work in a way that SSL_write() returns a value suitable for a UDP datagram so I send it and then call SS_write() again by passing the following chuck in my data buffer. Is it a bug? or am I missing something? Thanks a lot. -- Iñaki Baz Castillo <i...@aliax.net> ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
