This sort of thing is why CTF was added to the toolchain :) abigail has support for it now, too... of course ioctls don't all specify which structures they manipulate, but for those that *do*...

ioctl() forever?

How does CTF help here? I read https://lwn.net/Articles/795384/ which seems to describe it as basically a more compact debug info format, which leaves me unsure how it would be useful for describing the kernel ABI in a more machine-readable way. I guess in theory you could build the whole kernel and then fish out the debug info, but that would take forever and only have the info for the specific binary that got built...
