Platform: AIX 5.3 Compiler: xlc_r SSL: openssl-0.9.7d Problem Description:
C++ code using non-blocking sockets. SSL_CTX_new(TLSv1_client_method()); SSL_CTX_set_mode(m_ctx, SSL_MODE_AUTO_RETRY); We are seeing instances where SSL_connect() returns -1, which is normal for non-blocking sockets. A call to SSL_get_error() always returns SSL_ERROR_SYSCALL while calls to SSL_want() will return either SSL_READING or SSL_WRITING. In the case of SSL_READING, a subsequent call to SSL_connect() will complete the handshake. However, when SSL_want() returns SSL_WRITING, we cannot proceed. For SSL_WRITING a subsequent call to SSL_connect() results in the socket closing unexpectedly. If we attach a callback to the socket, an infinite callback loop ensues. If we wait and reissue the SSL_want(), SSL_WRITING is always returned. How do we proceed when faced with the SSL_WRITING state during the handshake? Thanks.
