Dive Into the Internals of Kernel Network Stack with Direct Code Execution - Hajime Tazaki, University of Tokyo

Network protocol is becoming complicated as a demand of users increases. There are still new protocols (e.g., Multipath-TCP) which are under development and need to study in detail, but it is hard to debug them once the issue comes from a distributed operation (the system is highly distributed.)

In this talk, he will firstly review the difficulties of debugging with network protocol development with the example of Linux kernel, then present a solution executing Linux kernel over a userspace program, with an alternative virtualization, Direct Code Execution (DCE), to address the hard-to-debug problem of distributed network protocols.

Then he will provide a couple of use cases, protocol debugging among distributed nodes with gdb, memory error detections of kernelspace program with valgrind, and code coverage measurement with the help of parameter sweeping of ns-3 network simulator.
