Abstract: 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.

Abstract: A disclosed method may include (1) providing a network stack that includes both a native stack and a proprietary stack, (2) implementing at least one socket that represents an endpoint of a communication channel between a network device and a computing device, (3) identifying at least one packet to be forwarded from the network device to the computing device via the socket, (4) configuring the network stack such that (A) the native stack discovers a maximum transmission unit of a network path between the network device and the computing device in connection with the socket and (B) the proprietary stack fragments the packet into a plurality of segments that each comply with the maximum transmission unit of the network path, and then (5) forwarding, along the network path, the segments to the computing device. Various other systems and methods are also disclosed.

Abstract: The problem of processing an egress packet by a data forwarding device having (1) a first routing stack associated with a first namespace and a first interface, (2) a second routing stack associated with a second namespace and a second interface, wherein at least some forwarding information included in the second namespace is incompatible with the first routing stack, (3) a virtual routing and forwarding instance (VRF), and (4) a shared session layer socket associated with both the first and second routing stack, and bound to the VRF, where the VRF is associated with the second interface via the second routing stack, is solved by: adding the first interface to the VRF whereby the VRF is associated with both the first and second interfaces; and responsive to the adding of the first interface to the VRF, (1) adding routes from the second namespace to the first namespace such that network address prefixes of the second namespace are associated with a “special” next hop, and (2) flagging the shared session layer socket bound to the VRF. When an egress packet on the flagged shared session layer socket is received, the data forwarding device (1) sends the egress packet to the first routing stack for processing, (2) looks up next hop information using the first namespace of the first routing stack, and (3) determines whether or not the next hop information is a “special” next hop. Responsive to a determination that the next hop information is a “special” next hop, the data forwarding device injects the egress packet into the second routing stack for processing.
