59f9097d5c Hand-conversion and audit phase of memcmp transition
Here I looked at the results of the automated conversion and cleaned
them up as follows:

   If there was a tor_memcmp or tor_memeq that was in fact "safe"[*] I
   changed it to a fast_memcmp or fast_memeq.

   Otherwise if there was a tor_memcmp that could turn into a
   tor_memneq or tor_memeq, I converted it.

This wants close attention.

[*] I'm erring on the side of caution here, and leaving some things
as tor_memcmp that could in my opinion use the data-dependent
fast_memcmp variant.

f7a3cdc8f2 Use observed instead of declared uptime for HSDir
It is important to verify the uptime claim of a relay instead of just
trusting it, otherwise it becomes too easy to blackhole a specific
hidden service. rephist already has data available that we can use here.

Bugfix on 0.2.0.10-alpha.

9b64227ffd Routers count as down when they change ORPort, too
rransom noticed that a change of ORPort is just as bad as a change of IP
address from a client's perspective, because both mean that the relay is
not available to them while the new information hasn't propagated.
Change the bug1035 fix accordingly.

Also make sure we don't log a bridge's IP address (which might happen
when we are the bridge authority).

feffbce814 Add a missing ! to directory_fetches_from_authorities
The old logic would have us fetch from authorities if we were refusing
unknown exits and our exit policy was reject*.  Instead, we want to
fetch from authorities if we're refusing unknown exits and our exit
policy is _NOT_ reject*.

Fixed by boboper.  Fixes more of 2097.  Bugfix on 0.2.2.16-alpha.

6c5b9ba625 Change bug1751 enabling code based on comments from arma 2010-09-27 17:07:22 -04:00
Nick Mathewson
ef5925237d First cut of code to enable RefuseUnknownExits
The RefuseUnknownExits config option is now a tristate, with "1"
meaning "enable it no matter what the consensus says", "0" meaning
"disable it no matter what the consensus says", and "auto" meaning "do
what the consensus says".  If the consensus is silent, we enable
RefuseUnknownExits.

This patch also changes the dirserv logic so that refuseunknownexits
won't make us cache unless we're an exit.

5926d9cfcc Move code for launching tests out of router_add_to_routerlist()
router_add_to_routerlist() is supposed to be a nice minimal function
that only touches the routerlist structures, but it included a call to
dirserv_single_reachability_test().

We have a function that gets called _after_ adding descriptors
successfully: routerlist_descriptors_added.  This patch moves the
responsibility for testing there.

Because the decision of whether to test or not depends on whether
there was an old routerinfo for this router or not, we have to first
detect whether we _will_ want to run the tests if the router is added.
We make this the job of
routers_update_status_from_consensus_networkstatus().

Finally, this patch makes the code notice if a router is going from
hibernating to non-hibernating, and if so causes a reachability test
to get launched.

23fdf0b30f Allow some skew in checking when a router said it was hibernating
This solves the problem Roger noted as:
   What if the router has a clock that's 5 minutes off, so it
   publishes a descriptor for 5 minutes in the future, and we test it
   three minutes in. In this edge case, we will continue to advertise
   it as Running for the full 45 minute period.
