My attic ceiling is carsiding pine boards that I would like to paint white. Is there any special primer to use? I have some exterior primer left over. Is that okay to use on this job?

I have no idea what carsiding is, ad you don't say what kind of exterior primer, but I'm going to say a big no on this one
It's almost always not a good idea to use ext. paints/primers inside
As for what to use, I can tell you that if it's clear unfinished pine, and you are painting with latex for the top coats, a quality latex primer will be fine
If it's knotty unfinished pine, that could get tricky w/o seeing it
Generally you'll want to prime with a quality oil-based (alkyd) primer, and check for bleed through before applying paint
(If there are any bleed through knots, they should get spot BINzed or other quality pigmented shellac)
If there' a ton of knots, or they are all dark and at high risk for bleed through, it might be better to BIN the whole thing
To ensure no future bleed through, BIN is best
If it's finished with something like poly, you'll need to scuff sand and oil-prime
