Option for downgrading "Rejecting SOCKS request for anonymous connection to private address" log
Tor Browser (or more precisely, both Tor Button and Tor Launcher) intentionally make requests via Tor to 127.0.0.1, because of #10682 (closed). See e.g. https://gitweb.torproject.org/tor-launcher.git/blob/HEAD:/src/install.rdf#l12
So we have a thin but steady stream of users who see
Rejecting SOCKS request for anonymous connection to private address [scrubbed]
warnings in their logs, and ask us what the deal is.
That said, in other situations I've actually found it useful for that warn to show up, since e.g. my Pidgin was making requests to 127.0.0.1 rather than to the xmpp server, and that was a bug in my Pidgin.
Does that argue for a torrc option that TB can set to indicate that it knows it'll be doing this otherwise-considered-broken behavior?
Hm.
