  ^^^^^^^^^ These ioctls are the interesting ones.

They can only make sense though if we know which fd they are being called
on and I don't see any socket(...) = 5 above so I can't tell what is going
wrong here. I would expect that the ioctl is being done on a socket but
its just possible that its the result of open() or dup(), etc. in case you don't
find a socket() = 5 in the trace anywhere.
