I am able to send and receive netlink messages between userspace processes as long as the genl family is registered by a kernel module. I am trying to remove the requirement of needing this module and register the family from userspace. However, judging by your last message that is not currently possible? Is that correct?</div></div></div><div><br></div><div>Thanks,</div><div><br></div><div>Lenny</div><div><br></div></div></div></span></body></html>
