Is it possible that we can add some loadable module into the kernel to
get a pid of a daemon-process and then somehow trace routing socket
messages coming in / going out from the kernel to that particular
daemon ?
  The thing why I am in need of this is that there are two daemons ,
one daemon is responsible for configuring the interfaces ...and the
second is actually awaiting the updates from the kernel ( that it
should send in case it sees that there is a change in the ifstate for
the interface ---IFD update) ... any resources /  material would be of
great help.Thanks and regards.
