A common task for most system services is to export a set of actions that do something. Until now, this meant loads of manual boilerplate code, error-prone request serialization, not quite consistent C++ interfaces, and lots of subtle (and blatant…) bugs. So I set out to find an RPC framework for use in kush-os to handle all of this for me.
I recently found myself needing reference counting semantics for arbitrary objects in kernel space. C++ libraries include std::shared_ptr and friends, but we don’t have the luxury of using that in a kernel. Thankfully, building a discount reference counting smart pointer isn’t actually all that hard.
