We detect and reject said attempts if there is no chosen exit node or
circuit: connecting to a private addr via a randomly chosen exit node
will usually fail (if all exits reject private addresses), is always
ill-defined (you're not asking for any particular host or service),
and usually an error (you've configured all requests to go over Tor
when you really wanted to configure all _remote_ requests to go over
Tor).
This can also help detect forwarding loop requests.
Found as part of bug2279.
Previously if you wanted to say "All messages except network
messages", you needed to say "[*,~net]" and if you said "[~net]" by
mistake, you would get no messages at all. Now, if you say "[~net]",
you get everything except networking messages.
We need to make sure that the worst thing that a weird consensus param
can do to us is to break our Tor (and only if the other Tors are
reliably broken in the same way) so that the majority of directory
authorities can't pull any attacks that are worse than the DoS that
they can trigger by simply shutting down.
One of these worse things was the cbtnummodes parameter, which could
lead to heap corruption on some systems if the value was sufficiently
large.
This commit fixes this particular issue and also introduces sanity
checking for all consensus parameters.
This was originally a patch provided by pipe
(http://www.mail-archive.com/or-talk@freehaven.net/msg13085.html) to
provide a method for controllers to query the total amount of traffic
tor has handled (this is a frequently requested piece of information
by relay operators).
The spec stated that support for the helper-nodes command would be removed
in 0.1.3.x, however support for this command is still in Tor. Updated the spec
to reflect this and added a node that the command is deprecated.
Several updates to grammars for events and GETINFO results. All relate
to the fact that LongName has replaced ServerID since 0.2.2.1-alpha. See
documentation of VERBOSE_NAMES for more information. The following
grammars were changed:
* orconn-status GETINFO result
* entry-guards GETINFO result
* Path general token
* OR Connection status changed event
* New descriptors available event
In all cases a note was added about when the old grammar applies.
