How to get a local IPv4 address from within a kernel module?

[Juan Gomez]

Is there any standard way of doing this? I looked into ipv4 code but I did
not find a function that would provide a direct, clean way to query the
local IPv4 addresses of a given node.
If this information is not available could we create an interface for it?
Any suggestions on the way to do it?

The interfaces provided to user-level applications do the copy to/from user
that I guess will not work with kernel modules...
