Revision f612bdb34252c3eae4808dd3e1360d0f0a3666bc authored by Matt Caswell on 04 November 2015, 11:20:50 UTC, committed by Matt Caswell on 10 December 2015, 12:50:56 UTC 
Ensure |rwstate| is set correctly on BIO_flush
 
A BIO_flush call in the DTLS code was not correctly setting the |rwstate|
variable to SSL_WRITING. This means that SSL_get_error() will not return
SSL_ERROR_WANT_WRITE in the event of an IO retry.
