10a6390deb Add controller getinfo exit-policy/reject-private
exit-policy/reject-private lists the reject rules added by
ExitPolicyRejectPrivate. This makes it easier for stem to
display exit policies.

Add unit tests for getinfo exit-policy/*.

Completes ticket #17183. Patch by "teor".

66fac9fbad Block OutboundBindAddressIPv[4|6]_ and configured ports on exit relays
Modify policies_parse_exit_policy_reject_private so it also blocks
the addresses configured for OutboundBindAddressIPv4_ and
OutboundBindAddressIPv6_, and any publicly routable port addresses
on exit relays.

Add and update unit tests for these functions.

c73c5a293f Refactor policies_parse_exit_policy_internal
Move the code that rejects publicly routable exit relay addresses
to policies_parse_exit_policy_reject_private. Add
addr_policy_append_reject_addr_list and use it to reject interface
addresses.

This removes the duplicate reject checks on local_address and
ipv6_local_address, but duplicates will be removed by
exit_policy_remove_redundancies at the end of the function.

This also removes the info-level logging on rejected interface
addresses. Instead, log a debug-level message in
addr_policy_append_reject_addr.

This simplifies policies_parse_exit_policy_internal and prepares for
reporting these addresses over the control port in #17183.

85bb71049a Fix a startup time assert caused by periodic events not being initialized.
Loading a on disk bridge descriptor causes a directory download to be
scheduled, which asserts due to the periodic events not being
initialized yet.

84b3350c83 Be more conservative in scanning the list of pending streams
Now we only re-scan the list in the cases we did before: when we
have a new circuit that we should try attaching to, or when we have
added a new stream that we haven't tried to attach yet.

This is part of 17590.

b1d56fc589 Decouple ..attach_circuit() from most of its callers.
Long ago we used to call connection_ap_handshake_attach_circuit()
only in a few places, since connection_ap_attach_pending() attaches
all the pending connections, and does so regularly.  But this turned
out to have a performance problem: it would introduce a delay to
launching or connecting a stream.

We couldn't just call connection_ap_attach_pending() every time we
make a new connection, since it walks the whole connection list.  So
we started calling connection_ap_attach_pending all over, instead!
But that's kind of ugly and messes up our callgraph.

So instead, we now have connection_ap_attach_pending() use a list
only of the pending connections, so we can call it much more
frequently.  We have a separate function to scan the whole
connection array to see if we missed adding anything, and log a
warning if so.

Closes ticket #17590

When parsing torrc ExitPolicies, we now warn if:
  * an IPv4 address is used on an accept6 or reject6 line. The line is
    ignored, but the rest of the policy items in the list are used.
    (accept/reject continue to allow both IPv4 and IPv6 addresses in torrcs.)
  * a "private" address alias is used on an accept6 or reject6 line.
    The line filters both IPv4 and IPv6 private addresses, disregarding
    the 6 in accept6/reject6.

When parsing torrc ExitPolicies, we now issue an info-level message:
  * when expanding an accept/reject * line to include both IPv4 and IPv6
    wildcard addresses.

In each instance, usage advice is provided to avoid the message.

07b3028db7 Prohibit the use of one entry node with an HS
In a nutshell, since a circuit can not exit at its entry point, it's very
easy for an attacker to find the hidden service guard if only one EntryNodes
is specified since for that guard, the HS will refuse to build a rendezvous
circuit to it.

For now, the best solution is to stop tor to allow a single EntryNodes for
an hidden service.

bab221f113 Refactor our logic for sending events to controllers
Previously we'd put these strings right on the controllers'
outbufs. But this could cause some trouble, for these reasons:

  1) Calling the network stack directly here would make a huge portion
     of our networking code (from which so much of the rest of Tor is
     reachable) reachable from everything that potentially generated
     controller events.

  2) Since _some_ events (EVENT_ERR for instance) would cause us to
     call connection_flush(), every control_event_* function would
     appear to be able to reach even _more_ of the network stack in
     our cllgraph.

  3) Every time we generated an event, we'd have to walk the whole
     connection list, which isn't exactly fast.

This is an attempt to break down the "blob" described in
http://archives.seul.org/tor/dev/Mar-2015/msg00197.html -- the set of
functions from which nearly all the other functions in Tor are
reachable.

* FIXES #16823: https://bugs.torproject.org/16823
   If an OP were to send a CREATE_FAST cell to an OR, and that
   CREATE_FAST cell had unparseable key material, then tor_free() would
   be called on the create cell twice.  This fix removes the second
   (conditional on the key material being bad) call to tor_free(), so
   that now the create cell is always freed once, regardless of the status of
   the key material.

   (This isn't actually a double-free bug, since tor_free() sets its
   input to NULL, and has no effect when called with input NULL.)

8c83e8cec0 Add get_max_sockets() and remove dead code
The control port was using set_max_file_descriptors() with a limit set to 0
to query the number of maximum socket Tor can use. With the recent changes
to that function, a check was introduced to make sure a user can not set a
value below the amount we reserved for non socket.

This commit adds get_max_sockets() that returns the value of max_sockets so
we can stop using that "setter" function to get the current value.

Finally, the dead code is removed that is the code that checked for limit
equal to 0. From now on, set_max_file_descriptors() should never be used
with a limit set to 0 for a valid use case.

Fixes #16697

7657194d77 Count intro circuit and not only established ones
When cleaning up extra circuits that we've opened for performance reason, we
need to count all the introduction circuit and not only the established ones
else we can end up with too many introduction points.

This also adds the check for expiring nodes when serving an INTRODUCE cell
since it's possible old clients are still using them before we have time to
close them.

d67bf8b2f2 Upload descriptor when all intro points are ready
To upload a HS descriptor, this commits makes it that we wait for all
introduction point to be fully established.

Else, the HS ends up uploading a descriptor that may contain intro points
that are not yet "valid" meaning not yet established or proven to work. It
could also trigger three uploads for the *same* descriptor if every intro
points takes more than 30 seconds to establish because of desc_is_dirty
being set at each intro established.

To achieve that, n_intro_points_established varialbe is added to the
rend_service_t object that is incremented when we established introduction
point and decremented when we remove a valid intro point from our list.

The condition to upload a descriptor also changes to test if all intro
points are ready by making sure we have equal or more wanted intro points
that are ready.

The desc_id_dirty flag is kept to be able to still use the
RendInitialPostPeriod option.

This partially fixes #13483.

1125a4876b Reuse intro points that failed but are still valid
There is a case where if the introduction circuit fails but the node is
still in the consensus, we clean up the intro point and choose an other one.
This commit fixes that by trying to reuse the existing intro point with a
maximum value of retry.

A retry_nodes list is added to rend_services_introduce() and when we remove
an invalid intro points that fits the use case mentionned before, we add the
node to the retry list instead of removing it. Then, we retry on them before
creating new ones.

This means that the requirement to remove an intro point changes from "if no
intro circuit" to "if no intro circuit then if no node OR we've reached our
maximum circuit creation count".

For now, the maximum retries is set to 3 which it completely arbitrary. It
should also at some point be tied to the work done on detecting if our
network is down or not.

7c7bb8b97e Refactor rend_services_introduce()
The reasoning for refactoring this function is that removing the
introduction point adaptative algorithm (#4862) ended up changing quite a
bit rend_services_introduce(). Also, to fix some open issues (#8239, #8864
and #13483), this work had to be done.

First, this removes time_expiring variable in an intro point object and
INTRO_POINT_EXPIRATION_GRACE_PERIOD trickery and use an expiring_nodes list
where intro nodes that should expire are moved to that list and cleaned up
only once the new descriptor is successfully uploaded. The previous scheme
was adding complexity and arbitrary timing to when we expire an intro point.
We keep the intro points until we are sure that the new descriptor is
uploaded and thus ready to be used by clients. For this,
rend_service_desc_has_uploaded() is added to notify the HS subsystem that
the descriptor has been successfully uploaded. The purpose of this function
is to cleanup the expiring nodes and circuits if any.

Secondly, this adds the remove_invalid_intro_points() function in order to
split up rend_services_introduce() a bit with an extra modification to it
that fixes #8864. We do NOT close the circuit nor delete the intro point if
the circuit is still alive but the node was removed from the consensus. Due
to possible information leak, we let the circuit and intro point object
expire instead.

Finally, the whole code flow is simplified and large amount of documentation
has been added to mostly explain the why of things in there.

68eaaed798 Avoid crashing on busy/NEWNYM+hidden service clients
When we ran out of intro points for a hidden service (which could
happen on a newnym), we would change the connection's state back to
"waiting for hidden service descriptor."  But this would make an
assertion fail if we went on to call circuit_get_open_circ_or_launch
again.

This fixes bug 16013; I believe the bug was introduced in
38be533c69, where we made it possible for
circuit_get_open_circ_or_launch() to change the connection's state.

e0b7598833 Repair breakage in early-error case of microdesc parsing
When I fixed #11243, I made it so we would take the digest of a
descriptor before tokenizing it, so we could desist from download
attempts if parsing failed.  But when I did that, I didn't remove an
assertion that the descriptor began with "onion-key".  Usually, this
was enforced by "find_start_of_next_microdescriptor", but when
find_start_of_next_microdescriptor returned NULL, the assertion was
triggered.

d4a6b1a420 Implement ed25519 identity collation for voting.
This is a new collator type that follows proposal 220 for deciding
which identities to include.  The rule is (approximately):

  If a <ed,rsa> identity is listed by more than half of authorities,
  include it.  And include all <rsa> votes about that node as
  matching.

  Otherwise, if an <*,rsa> or <rsa> identity is listed by more than
  half of the authorities, and no <ed,rsa> has been listed, include
  it.

592a439107 Tie key-pinning logic into directory authority operation
With this patch:
  * Authorities load the key-pinning log at startup.
  * Authorities open a key-pinning log for writing at startup.
  * Authorities reject any router with an ed25519 key where they have
    previously seen that ed25519 key with a different RSA key, or vice
    versa.
  * Authorities warn about, but *do not* reject, RSA-only descriptors
    when the RSA key has previously gone along with an Ed25519 key.
    (We should make this a 'reject' too, but we can't do that until we're
    sure there's no legit reason to downgrade to 0.2.5.)

eacbe03c71 Key-pinning back-end for directory authorities.
This module implements a key-pinning mechanism to ensure that it's
safe to use RSA keys as identitifers even as we migrate to Ed25519
keys.  It remembers, for every Ed25519 key we've seen, what the
associated Ed25519 key is.  This way, if we see a different Ed25519
key with that RSA key, we'll know that there's a mismatch.

We persist these entries to disk using a simple format, where each
line has a base64-encoded RSA SHA1 hash, then a base64-endoded
Ed25519 key.  Empty lines, misformed lines, and lines beginning with
a # are ignored. Lines beginning with @ are reserved for future
extensions.

db7bde08be Add "HiddenServiceMaxStreams" as a per-HS tunable.
When set, this limits the maximum number of simultaneous streams per
rendezvous circuit on the server side of a HS, with further RELAY_BEGIN
cells being silently ignored.

This can be modified via "HiddenServiceMaxStreamsCloseCircuit", which
if set will cause offending rendezvous circuits to be torn down instead.

The length of auth_data from an INTRODUCE2 cell is checked when the
auth_type is recognized (1 or 2), but not for any other non-zero
auth_type. Later, auth_data is assumed to have at least
REND_DESC_COOKIE_LEN bytes, leading to a client-triggered out of bounds
read.

Fixed by checking auth_len before comparing the descriptor cookie
against known clients.
