Patches look correct, one small nit here -

I don't have great ideas how to avoid the 7th argument completely but 
I think it'd be a little cleaner if we either:
 - passed in err as an output argument (some datagram code does that
   IIRC), then function can always return copied directly, or 
 - passed copied as an output argument, and then we can always return
   err?
I like the former a little better because we won't have to special case
NULL for the "after async decryption" call sites.
