In what context (or rather in whose thread) does the callback code (functions like sf_bind_func) operate? What if i am waiting there for a usermode process to send me some command via kernel_control? What else will freeze, except my function? the whole networking subsystem? In what context myNKE_start() and myNKE_stop() are executed? What if i perform some lengthy operations in there? What about kernel_control's callback functions? If i am, for example, establishing a connection with a remote host (which is not a quick action), from "EPHandleGetSockOpt", will only usermode process, which called "getsockopt", freeze? Or something else will degrade as well? What is the common rule to perform such operations? Creating my own thread and waiting for callbacks from it?
