Both actually. I've slightly simplified the situation, because you may not care for all the details, but if you want to know the gory details... It's all started with some kernel drivers changing the way they handle ESSID. That was last January. So, in the kernel, you had half the drivers doing the old way (NUL terminated), and half doing the new way (not NUL terminated). I immediately asked to revert to the old way. All the Wireless people were against me, and this mish-mash of API was kept (it was public on netdev). At this point, nobody cared that userspace API was broken and I was left cleaning up the mess. Of course, some part of the Wireless Tools did broke on the new API (I had bug reports), so I had to push new version of Wireless Tools. And I took this opportunity to finish moving over the API to the new way.
Sometime breaking userspace APIs is perfectly OK, while sometimes it's not. You just have to make sure that Linus does not hear about it, I guess ;-)
