But, in the case, we must think of the case of changing IP address
because we can change IP address without disabling the network device and
can't hook the event of changing IP address.
Well, updating the local _IP_ address (for a particular interface) as
and when it changes would also be good ... it is another piece of info
exposed (read-write) to userspace through configfs, so makes sense to
keep it uptodate.
[...] (as long as it doesn't break
anything, as Matt warned earlier). I'm not aware of any existing
netdevice notifier that'll do this, so I'll look around (or trace
an ifconfig(8) / ip(8) to see what actually happens).
I think inetaddr_chain / register_inetaddr_notifier() are what I'm
looking for. I'll see if this does the job for us without breaking
anything else.
