Hi Junxiao, then:

No attacks in particular, it was just a stupid example in order to
explain if the operation of calling onInterestFinalize was possible
locally in an NFD :)

Assumption, like above :) The example was very stupid just to explain
better the feasibility of "remove an interest from the PIT without
satisfy it with nack or data"

If we focus on this example, just modifying the code of all the NFD
inside an institution :)
Probably a better example helps better to express my question.
I am Jon and I know that Peter is my enemy. I don't want to receive
anything from him. Jon offers services public in the world, but for
his reason he doesn t want to perform this service to Peter. Jon
desire to remove the Peter Interests as soon as possible without
satisfy them neither with a data or nack. The PIT table has just space
for 3 interests pending per time, then It is suitable do not occupy
it. Jon could modify its NFD in order to do:
if the interest received is from Peter then
remove it by my PIT
?
Thanks a lot,
Matteo :)
