734fad4103 Make relays handle an address suggestion from a directory server giving an IPv6 address. 
last_guessed_ip becomes a tor_addr_t.

Most parts of router_new_address_suggestion() learns
about IPv6 (resolve_my_address() is still IPv4 only).

b5a8c3aa00 Remove misleading function comment (bug 5324) 
In the distant past, connection_handle_read() could be called when there
are pending bytes in the TLS object during the main loop. The design
since then has been to always read all pending bytes immediately, so
read events only trigger when the socket actually has bytes to read.

Resolves bug 5324.

Nick Mathewson
60b42d68f3 Try to have (and maintain!) an invariant about unconfigured_proxies_n 
The invariant is: unconfigured_proxies_n is exactly the number of
managed_proxy_t not in state PT_PROTO_COMPLETED.

To maintain this, we need to stop overloading unconfigured_proxies_n
to also count managed_proxy_t items that are in PT_PROTO_COMPLETED but
which might need relaunching.  To make it so we can detect those, we
introduce another variable.

This commit also adds a function to assert that we haven't broken the
invariant.

Fix for bug 5084; bugfix on 0.2.3.6-alpha, I think.

fff511a5e7 Don't smartlist_remove a managed proxy from a list we're iterating over. 
In some cases, we solve this by doing a SMARTLIST_DEL_CURRENT before
calling managed_proxy_destroy.  But for a trickier one, we just make a
copy of the list before iterating over it, so that changes to the
manage proxy list don't hurt our iteration.

This could be related to bug 5084.

b1ee1927b1 if we ever have an old bridge, never again use microdescs

a0f0897795 Allow 0.2.3.x clients to use 0.2.2.x bridges. 
Previously the client would ask the bridge for microdescriptors, which are
only supported in 0.2.3.x and later, and then fail to bootstrap when it
didn't get the answers it wanted. Fixes bug 4013; bugfix on 0.2.3.2-alpha.

The fix here is to revert to using normal descriptors if any of our
bridges are known to not support microdescs. This is not ideal, a) because
we'll start downloading a microdesc consensus as soon as we get a bridge
descriptor, and that will waste time if we later get a bridge descriptor
that tells us we don't like microdescriptors; and b) by changing our mind
we're leaking to our other bridges that we have an old-version bridge.

The alternate fix would have been to change
we_use_microdescriptors_for_circuits() to ask if *any* of our bridges
can support microdescriptors, and then change the directory logic that
picks a bridge to only select from those that do. For people living in
the future, where 0.2.2.x is obsolete, there won't be a difference.

Note that in either of these potential fixes, we have risk of oscillation
if our one funny-looking bridges goes away / comes back.

69d16900aa Refactor addressmap_match_superdomains and representation of wildcards 
In this new representation for wildcarded addresses, there are no
longer any 'magic addresses': rather, "a.b c.d", "*.a.b c.d" and
"*.a.b *.c.d" are all represented by a mapping from "a.b" to "c.d". we
now distinguish them by setting bits in the addressmap_entry_t
structure, where src_wildcard is set if the source address had a
wildcard, and dst_wildcard is set if the target address had a
wildcard.

This lets the case where "*.a.b *.c.d" or "*.a.b c.d" remap the
address "a.b" get handled trivially, and lets us simplify and improve
the addressmap_match_superdomains implementation: we can now have it
run in O(parts of address) rather than O(entries in addressmap).

1. Only allow '*.' in MapAddress expressions. Ignore '*ample.com' and '.example.com'.
       This has resulted in a slight refactoring of config_register_addressmaps.
    2. Add some more detail to the man page entry for AddressMap.
    3. Fix initialization of a pointer to NULL rather than 0.
    4. Update the unit tests to cater for the changes in 1 and test more explicitly for
       recursive mapping.

1. Implement the following mapping rules:

   MapAddress a.b.c d.e.f # This is what we have now
   MapAddress .a.b.c d.e.f # Replaces any address ending with .a.b.c with d.e.f
   MapAddress .a.b.c .d.e.f # Replaces the .a.b.c at the end of any addr with .d.e.f

   (Note that 'a.b.c .d.e.f' is invalid, and will be rejected.)

2. Add tests for the new rules.

3. Allow proper wildcard annotation, i.e. '*.d.e' '.d.e' will still work.

4. Update addressmap_entry_t with an is_wildcard member.

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.

5f0a8dcd2c Initial hacking for proposal 186. 
This code handles the new ORPort options, and incidentally makes all
remaining port types use the new port configuration systems.

There are some rough edges!  It doesn't do well in the case where your
Address says one thing but you say to Advertise another ORPort.  It
doesn't handle AllAddrs.  It doesn't actually advertise anything besides
the first listed advertised IPv4 ORPort and DirPort.  It doesn't do
port forwarding to them either.

It's not tested either, it needs more documentation, and it probably
forgets to put the milk back in the refrigerator.

df9b76460c New 'DisableNetwork' option to prevent Tor from using the network 
Some controllers want this so they can mess with Tor's configuration
for a while via the control port before actually letting Tor out of
the house.

We do this with a new DisableNetwork option, that prevents Tor from
making any outbound connections or binding any non-control
listeners.  Additionally, it shuts down the same functionality as
shuts down when we are hibernating, plus the code that launches
directory downloads.

To make sure I didn't miss anything, I added a clause straight to
connection_connect, so that we won't even try to open an outbound
socket when the network is disabled.  In my testing, I made this an
assert, but since I probably missed something, I've turned it into a
BUG warning for testing.

No promises about the particular future location or semantics for this:
we will probably want to tweak it some before 0.2.3.x-rc

e3cee8bc2e Simply initialize TLS context if DynamicDHGroups change. 
We used to do init_keys() if DynamicDHGroups changed after a HUP, so
that the dynamic DH modulus was stored on the disk. Since we are now
doing dynamic DH modulus storing in crypto.c, we can simply initialize
the TLS context and be good with it.

Introduce a new function router_initialize_tls_context() which
initializes the TLS context and use it appropriately.

6e6a661296 New UserspaceIOCPBuffers option to set SO_{SND,RCV}BUF to zero 
When running with IOCP, we are in theory able to use userspace-
allocated buffers to avoid filling up the stingy amount of kernel
space allocated for sockets buffers.

The bufferevent_async implementation in Libevent provides this
ability, in theory.  (There are likely to be remaining bugs).  This
patch adds a new option that, when using IOCP bufferevents, sets
each socket's send and receive buffers to 0, so that we should use
this ability.

When all the bugs are worked out here, if we are right about bug 98,
this might solve or mitigate bug 98.

This option is experimental and will likely require lots of testing
and debugging.

d4489a2851 Rewrite comment at head of eventdns.c 
Let's make it more obvious to the everyday reader that eventdns.c is
  a) Based on Libevent's evdns.c
  b) Slated for demolition
  c) Supposed to keep API-compatibility with Libevent.
  d) Not worth tweaking unless there's a bug.

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.)
