[ros-dev] Empty fields of DeviceNode leading to Death

[art yerkes]

Is there a reference for which registry keys fill (or are supposed to fill)
which members of DeviceNode?  I ask because I wind up finding all of the
combinations that lead to zeros and have a tough time figuring out which
registry values are needed to make them not be zero.

We have a lot of unchecked string functions on the DeviceNode fields in
io/pnpmgr.c, by the way.  I think i've stumbled on four such places so
far, but I suspect that the whole thing should be hardened together.

In any case it would be nice if someone could post a cheat sheet about
how to create a new device entry the right way, or write the code that
fills the DeviceNode in a more obvious way, so that it's easy to find
and see what fills what.

Here's a simple experiment. Stand on a train track between two locomotives
which are pushing on you with equal force in opposite directions. You will
exhibit no net motion. None the less, you may soon begin to notice that
something important is happening.
