f786307ab7 First chunk of support for bridges on IPv6
Comments below focus on changes, see diff for added code.

New type tor_addr_port_t holding an IP address and a TCP/UDP port.

New flag in routerinfo_t, ipv6_preferred.  This should go in the
node_t instead but not now.

Replace node_get_addr() with
- node_get_prim_addr() for primary address, i.e. IPv4 for now
- node_get_pref_addr() for preferred address, IPv4 or IPv6.

Rename node_get_addr_ipv4h() node_get_prim_addr_ipv4h() for
consistency.  The primary address will not allways be an IPv4 address.
Same for node_get_orport() -> node_get_prim_orport().

Rewrite node_is_a_configured_bridge() to take all OR ports into account.

Extend argument list to extend_info_from_node and
extend_info_from_router with a flag indicating if we want to use the
routers primary address or the preferred address.  Use the preferred
address in as few situtations as possible for allowing clients to
connect to bridges over IPv6.

00885652db Allow intro points to expire somewhat gracefully
The Right Way to expire an intro point is to establish a new one to
replace it, publish a new descriptor that doesn't list any expiring intro
points, and *then*, once our upload attempts for the new descriptor have
ended (whether in success or failure), close the expiring intro points.

Unfortunately, we can't find out when the new descriptor has actually been
uploaded, so we'll have to settle for a five-minute timer.

There should be no significant behaviour changes due to this commit (only
a log-message change or two), despite the rather massive overhaul, so this
commit doesn't include a changes/ file.  (The commit that teaches
intro_point_should_expire_now to return non-zero gets a changes/ file,
though.)

00b2b69add Fix names of functions that convert strings to addrs
Now let's have "lookup" indicate that there can be a hostname
resolution, and "parse" indicate that there wasn't.  Previously, we
had one "lookup" function that did resolution; four "parse" functions,
half of which did resolution; and a "from_str()" function that didn't
do resolution.  That's confusing and error-prone!

The code changes in this commit are exactly the result of this perl
script, run under "perl -p -i.bak" :

  s/tor_addr_port_parse/tor_addr_port_lookup/g;
  s/parse_addr_port(?=[^_])/addr_port_lookup/g;
  s/tor_addr_from_str/tor_addr_parse/g;

This patch leaves aton and pton alone: their naming convention and
behavior is is determined by the sockets API.

More renaming may be needed.

64c8e8edda Kill redundant checks around routerset_contains_*()
All of the routerset_contains*() functions return 0 if their
routerset_t argument is NULL.  Therefore, there's no point in
doing "if (ExcludeNodes && routerset_contains*(ExcludeNodes...))",
for example.

This patch fixes every instance of
         if (X && routerstatus_contains*(X,...))

Note that there are other patterns that _aren't_ redundant.  For
example, we *don't* want to change:
        if (EntryNodes && !routerstatus_contains(EntryNodes,...))

Fixes #2797.  No bug here; just needless code.

54d7d31cba Make ControlSocketsGroupWritable work with User.
Original message from bug3393:

check_private_dir() to ensure that ControlSocketsGroupWritable is
safe to use. Unfortunately, check_private_dir() only checks against
the currently running user… which can be root until privileges are
dropped to the user and group configured by the User config option.

The attached patch fixes the issue by adding a new effective_user
argument to check_private_dir() and updating the callers. It might
not be the best way to fix the issue, but it did in my tests.

b95dd03e5f Log descriptions of nodes, not just nicknames.
This patch introduces a few new functions in router.c to produce a
more helpful description of a node than its nickame, and then tweaks
nearly all log messages taking a nickname as an argument to call these
functions instead.

There are a few cases where I left the old log messages alone: in
these cases, the nickname was that of an authority (whose nicknames
are useful and unique), or the message already included an identity
and/or an address.  I might have missed a couple more too.

This is a fix for bug 3045.

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.

79a3b3cd37 Check transition of circuit purpose from INTRO->GENERAL if nodes are constrained
This looked at first like another fun way around our node selection
logic: if we had introduction circuits, and we wound up building too
many, we would turn extras into general-purpose circuits.  But when we
did so, we wouldn't necessarily check whether the general-purpose
circuits conformed to our node constraints.  For example, the last
node could totally be in ExcludedExitNodes and we wouldn't have cared...

...except that the circuit should already be internal, so it won't get user
streams attached to it, so the transition should generally be allowed.
Add an assert to make sure we're right about this, and have it not
check whether ExitNodes is set, since that's irrelevant to internal
circuits.

26e897420e Initial conversion to use node_t throughout our codebase.
A node_t is an abstraction over routerstatus_t, routerinfo_t, and
microdesc_t.  It should try to present a consistent interface to all
of them.  There should be a node_t for a server whenever there is
  * A routerinfo_t for it in the routerlist
  * A routerstatus_t in the current_consensus.
(note that a microdesc_t alone isn't enough to make a node_t exist,
since microdescriptors aren't usable on their own.)

There are three ways to get a node_t right now: looking it up by ID,
looking it up by nickname, and iterating over the whole list of
microdescriptors.

All (or nearly all) functions that are supposed to return "a router"
-- especially those used in building connections and circuits --
should return a node_t, not a routerinfo_t or a routerstatus_t.

A node_t should hold all the *mutable* flags about a node.  This
patch moves the is_foo flags from routerinfo_t into node_t.  The
flags in routerstatus_t remain, but they get set from the consensus
and should not change.

Some other highlights of this patch are:

  * Looking up routerinfo and routerstatus by nickname is now
    unified and based on the "look up a node by nickname" function.
    This tries to look only at the values from current consensus,
    and not get confused by the routerinfo_t->is_named flag, which
    could get set for other weird reasons.  This changes the
    behavior of how authorities (when acting as clients) deal with
    nodes that have been listed by nickname.

  * I tried not to artificially increase the size of the diff here
    by moving functions around.  As a result, some functions that
    now operate on nodes are now in the wrong file -- they should
    get moved to nodelist.c once this refactoring settles down.
    This moving should happen as part of a patch that moves
    functions AND NOTHING ELSE.

  * Some old code is now left around inside #if 0/1 blocks, and
    should get removed once I've verified that I don't want it
    sitting around to see how we used to do things.

There are still some unimplemented functions: these are flagged
with "UNIMPLEMENTED_NODELIST()."  I'll work on filling in the
implementation here, piece by piece.

I wish this patch could have been smaller, but there did not seem to
be any piece of it that was independent from the rest.  Moving flags

fcbd65b45c Refactor the safe_str_*() API to make more sense.
The new rule is: safe_str_X() means "this string is a piece of X
information; make it safe to log."  safe_str() on its own means
"this string is a piece of who-knows-what; make it safe to log".

3807db001d *_free functions now accept NULL
Some *_free functions threw asserts when passed NULL. Now all of them
accept NULL as input and perform no action when called that way.

This gains us consistence for our free functions, and allows some
code simplifications where an explicit null check is no longer necessary.

d2b4b49ff0 Reduce log level for someone else sending us weak DH keys.
See task 1114. The most plausible explanation for someone sending us weak
DH keys is that they experiment with their Tor code or implement a new Tor
client. Usually, we don't care about such events, especially not on warn
level. If we really care about someone not following the Tor protocol, we
can set ProtocolWarnings to 1.

fe221f3dff Start the process of treating internal circuits and exit circuits
separately. It's important to keep them separate because internal
circuits have their last hops picked like middle hops, rather than like
exit hops. So exiting on them will break the user's expectations.

- Stop cannibalizing internal circuits for general exits, and stop
  cannibalizing exit circuits for rendezvous stuff.

- Don't let new exit streams attach to internal circuits.

- When deciding if we have enough circuits for internal and for exit,
  don't count the wrong ones.

- Treat predicted resolves as predicted port 80 exits.

ec83652357 Logic to implement rendezvous/introduction via unknown servers.
- Add a new extend_info_t datatype to hold information needed to
  extend a circuit (addr,port,keyid,onion_key).  Use it in cpath and
  build_state.  Make appropriate functions take or return it instead of
  routerinfo_t or keyid.

- #if 0 needless check in circuit_get_by_edge_conn; if nobody triggers this
  error in 0.1.0.10, nobody will trigger it.

- Implement new hidden service descriptor format, which contains "extend
  info" for introduction points, along with protocol version list.
  - Parse new format.
  - Generate new format
  - Cache old and new formats alongside each other.
  - Directories serve "old" format if asked in old way, "newest available"
    format if asked in new way.
  - Use new format to find introduction points if possible; otherwise fall
    back.  Keep nickname lists and extendinfo lists in sync.
  - Tests for new format.

- Implement new "v2" INTRODUCE cell format.
  - Accept new format
  - Use new format if we have a versioned service descriptor that says the
    server accepts the new format.

- Add documentation for functions and data types.

d2400a5afd Introduce a notion of 'internal' circs, which are chosen without regard
to the exit policy of the last hop. Intro and rendezvous circs must
be internal circs, to avoid leaking information. Resolve and connect
streams can use internal circs if they want.

New circuit pooling algorithm: make sure to have enough circs around
to satisfy any predicted ports, and also make sure to have 2 internal
circs around if we've required internal circs lately (with high uptime
if we've seen that lately).

Split NewCircuitPeriod config option into NewCircuitPeriod (30 secs),
which describes how often we retry making new circuits if current ones
are dirty, and MaxCircuitDirtiness (10 mins), which describes how long
we're willing to make use of an already-dirty circuit.

Once rendezvous circuits are established, keep using the same circuit as
long as you attach a new stream to it at least every 10 minutes. (So web
browsing doesn't require you to build new rend circs every 30 seconds.)

Cannibalize GENERAL circs to be C_REND, C_INTRO, S_INTRO, and S_REND
circ as necessary, if there are any completed ones lying around when
we try to launch one.

Re-instate the ifdef's to use version-0 style introduce cells, since
there was yet another bug in handling version-1 style. We'll try switching
over again after 0.0.9 is obsolete.

Bugfix: when choosing an exit node for a new non-internal circ, don't take
into account whether it'll be useful for any pending x.onion addresses --
it won't.

Bugfix: we weren't actually publishing the hidden service descriptor when
it became dirty. So we only published it every 20 minutes or so, which
means when you first start your Tor, the hidden service will seem broken.

New config option LongLivedPorts to indicate application streams

When attaching a stream to a circuit, pay attention to its requirements.

This means that every single node in an intro rend circuit, not just
the last one, will have a minimum uptime.
