commit bca09d443ff450113f7d46a0da204e500ef26f4e
Author: Damian Johnson <ata...@torproject.org>

Differentiate between app resolution by local/remote ports
Our helper for resolving applications by their port lets us differentiate
between the local and remote port. When using it we said ports were both,
but
the connection lines know the difference. Plumbing it through to get more
accurate results.
