The disclosed computer-implemented method may include (1) providing a framework that includes (A) a user-space component that runs at a client site and (B) a kernel-space component that runs at a remote site, (2) identifying attributes of objects that reside at the remote site and whose addresses are unknown at the client site, (3) generating a script to test a function of a kernel running on the remote site based at least in part on the attributes, and (4) performing a remote unit testing of the function of the kernel by executing the script such that the user-space component (A) generates a message that identifies the attributes and (B) sends the message to the kernel-space component to facilitate (I) obtaining references to the objects by way of the attributes and (II) invoking the function by way of the references. Various other methods, systems, and computer-readable media are also disclosed.

Techniques are described for providing an indication of an impending control plane disruption of a router using forwarding plane liveliness detection protocols. A forwarding plane of the router outputs liveliness detection messages that, when received by a peer router, provide an indication that the forwarding plane is operational and able to forward packets. When constructing the liveliness detection messages, the forwarding plane may embed additional information indicative of any impending disruption in the control plane of the network device. In this way, the forwarding plane of the transmitting router provides an indication to the peer router that, although currently operational, the control plane of the router may in the near term become non-operational. The peer router, in response to receiving an enhanced liveliness detection message indicating an impending control plane disruption, suppresses a recovery action otherwise triggered by a loss of communication with a control plane of the network device.
