Log:
remove the exit enclaving faq entry
(exit enclaving doesn't work for most users now, since most users only
see the summary exit policy, which describes ports but not addresses.)
this would be a good candidate for an ifaq, if we had one, to explain
what this feature used to be.

- When a machine that runs a Tor relay also runs a public service, such as
- a webserver, you can configure Tor to offer Exit Enclaving to that
- service. Running an Exit Enclave for all of your services you wish to
- be accessible via Tor provides your users the assurance that they will
- exit through your server, rather than exiting from a randomly selected
- exit node that could be watched. Normally, a tor circuit would end at
- an exit node and then that node would make a connection to your service.
- Anyone watching that exit node could see the connection to your service,
- and be able to snoop on the contents if it were an unencrypted
- connection. If you run an Exit Enclave for your service, then the exit
- from the Tor network happens on the machine that runs your service,
- rather than on an untrusted random node. This works when Tor clients
- wishing to connect to this public service extend their circuit
- to exit from the Tor relay running on that same host. For example, if
- the server at 1.2.3.4 runs a web server on port 80 and also acts as a
- Tor relay configured for Exit Enclaving, then Tor clients wishing to
- connect to the webserver will extend their circuit a fourth hop to exit
- to port 80 on the Tor relay running on 1.2.3.4.
- </p>
- <p>
- Exit Enclaving is disabled by default to prevent attackers from
- exploiting trust relationships with locally bound services. For
- example, often 127.0.0.1 will run services that are not designed to
- be shared with the entire world. Sometimes these services will also
- be bound to the public IP address, but will only allow connections if
- the source address is something trusted, such as 127.0.0.1.
- </p>
- <p>
- As a result of possible trust issues, relay operators must configure
- their exit policy to allow connections to themselves, but they should
- do so only when they are certain that this is a feature that they would
- like. Once certain, turning off the ExitPolicyRejectPrivate option will
- enable Exit Enclaving. An example configuration would be as follows:
- </p>
- <pre>
- ExitPolicy accept 1.2.3.4:80
- ExitPolicy reject 127.0.0.1/8
- ExitPolicyRejectPrivate 0
- </pre>
- <p>
- This option should be used with care as it may expose internal network
- blocks that are not meant to be accessible from the outside world or
- the Tor network. Please tailor your ExitPolicy to reflect all netblocks
- that you want to prohibit access.

- While useful, this behavior may go away in the future because it is
- imperfect. A great idea but not such a great implementation.
