When zmq::req_t::xrecv detects that a response has no request ID label, or the ID is the wrong size, it would return an EAGAIN, but would not discard the remainder of the message. This could allow the remainder of the message to incorrectly "leak" into a future response, if it is crafted to look like a reply with a valid response ID. Discard all remaining message blocks, if the ID is invalid in any way.
Welcome ------- The 0MQ lightweight messaging kernel is a library which extends the standard socket interfaces with features traditionally provided by specialised messaging middleware products. 0MQ sockets provide an abstraction of asynchronous message queues, multiple messaging patterns, message filtering (subscriptions), seamless access to multiple transport protocols and more. Building and installation ------------------------- See the INSTALL file included with the distribution. Resources --------- Extensive documentation is provided with the distribution. Refer to doc/zmq.html, or "man zmq" after you have installed 0MQ on your system.
