Project description
The libnv library allows to easily manage name value pairs as well as send and receive them over sockets. You are able to add bools, strings, numbers, descriptors, binaries or even nest one nvlist in another. Nvlist has a great potential since it’s API simplifies the work done by a developers. In this project I will struggle to expand its functionality and port the library to other platforms.
Deliverables
- cnv API (functions based on cookie, not on the name of pair)
- JSON conversion
- Porable libnv repository
- Improve complexity of nvlist by applying built-in macro for red-black tree
- Replace binary structures with SYSCTL_NVLIST in few tools
- Make libnv work with

Test Plan
Each part of my project needs to be tested. I will create similar tests for cnv API as the authors did in other APIs. In this case I’m going to use ATF and Kyua framework. My tests will also cover conversion to JSON, UCL and SYSCTL_NVLIST structure. When I apply successfully the red-black tree macro, I’m going to rerun the tests created by the authors. Other techniques, that I’m willing to use could include fuzzing, using AFL tool.
