[Boost-users] Debugging openssl server and asio

Hi I'm trying to hack cpp-netlib to implement a https server. I have used the ssl server example from boost 1.46.1 which is working okay, but when I (think) I do the same thing in cpp-net lib I got this segmentation fault: #0 0x00007ffff7bbda57 in SSL_accept () from /usr/lib64/libssl.so.1.0.0 #1 0x00000000004c1702 in boost::network::http::sync_connection::socket (this=0x4d58ca) at /home/awn/git/buildroot5/git/gmbinit/test/cpp-netlib-0.9.2/boost/network/protocol/http/server/sync_connection.hpp:50 #2 0x00000000004d4e67 in boost::detail::function::function_invoker1::invoke (function_ptr=..., a0=0x731820) at /usr/include/boost-1_46/boost/function/function_template.hpp:95 #3 0x00000000004d0fd6 in boost::function1::operator() (this=0x73b490, a0=0x731820) at /usr/include/boost-1_46/boost/function/function_template.hpp:1013 #4 0x00000000004cde2f in boost::asio::ssl::detail::openssl_operationboost::asio::ip::tcp > >::start (this=0x73b490) at /usr/include/boost-1_46/boost/asio/ssl/detail/openssl_operation.hpp:149 #5 0x00000000004df1b3 in boost::_mfi::mf0boost::asio::ip::tcp > > >::operator() ( this=0x7fffffffc500, p=0x73b490) at /usr/include/boost-1_46/boost/bind/mem_fn_template.hpp:49 #6 0x00000000004dd693 in boost::_bi::list1boost::asio::ip::tcp > >*>

As the problem is in SSL_accept () i expect there is something wrong with my SSL context which I create like this: boost::asio::ssl::context context_(io_service, boost::asio::ssl::context::sslv23); context_.set_verify_mode(boost::asio::ssl::context::verify_none); context_.use_certificate_chain_file("/etc/ssl/gamblify/gamblify.cert"); context_.use_private_key_file("/etc/ssl/gamblify/gamblify.pem", boost::asio::ssl::context::pem); The context is created in my main function, and then passed around as a reference. The type of my socket is: boost::asio::ssl::streamboost::asio::ip::tcp::socket socket_; I create it like this: socket_(service_, context) Accept is using the lowest layer which I return like this boost::asio::ssl::streamboost::asio::ip::tcp::socket::lowest_layer_type& socket() { return socket_.lowest_layer(); } I call async_accept like this: new_connection.reset(new sync_connection(service_, handler_, context_)); acceptor_.async_accept(new_connection->socket(), boost::bind(&sync_server_base::handle_accept, this, boost::asio::placeholders::error)); The handler looks like this: void handle_accept(boost::system::error_code const & ec) { if (!ec) { new_connection->start(); new_connection.reset(new sync_connection(service_, handler_, context_)); acceptor_.async_accept(new_connection->socket(), boost::bind(&sync_server_base::handle_accept, this, boost::asio::placeholders::error)); } } Eventually the accept handler and it is running start which looks like this: void start() { std::cerr << "Running start" << std::endl; socket_.async_handshake(boost::asio::ssl::stream_base::server, boost::bind(&sync_connection::handle_handshake, this, boost::asio::placeholders::error)); } Then at some point before I reach the handle_handshake I get an segmentation fault... Can any body see any problems with this, or just give some hints on how to debug this kind of bugs... -- Allan W. Nielsen
