Testing tor networks use external DNS for dns checks
When I launch a test network using
make test-network / chutney on OS X, and leave it running for about a minute, one of the tor processes makes DNS calls.
I discovered this because LittleSnitch told me tor was trying to connect to the local network's DNS server. I don't know where this happens in the tor code.
Marking this as major / Post027Freeze as it could be an information leak. Alternately, it could be an attempt to look up an address that chutney is (mis)configuring for tor.
I'm not quite sure how to tell the difference between an information leak and a misconfiguration, it may take me some time.
