ae98dd255b Check that openssl has ECC support during configure
This allows builds on machines with a crippled openssl to fail early
during configure. Bugfix on 0.2.7.1-alpha, which introduced the

098b82c7b2 ExitPolicyRejectPrivate rejects local IPv6 address and interface addresses
ExitPolicyRejectPrivate now rejects more local addresses by default:
 * the relay's published IPv6 address (if any), and
 * any publicly routable IPv4 or IPv6 addresses on any local interfaces.

This resolves a security issue for IPv6 Exits and multihomed Exits that
trust connections originating from localhost.

d3358a0a05 ExitPolicy accept6/reject6 produces IPv6 wildcard addresses only

e033d5e90b Ignore accept6/reject6 IPv4, warn about unexpected rule outcomes
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.

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.

da6aa7bfa5 Allow a single trailing . when validating FQDNs from SOCKS.
URI syntax (and DNS syntax) allows for a single trailing `.` to
explicitly distinguish between a relative and absolute
(fully-qualified) domain name. While this is redundant in that RFC 1928
DOMAINNAME addresses are *always* fully-qualified, certain clients
blindly pass the trailing `.` along in the request.

Fixes bug 16674; bugfix on 0.2.6.2-alpha.

840e68d917 Integrate and enable ed25519-donna.
The runtime sanity checking is slightly different from the optimized
basepoint stuff in that it uses a given implementation's self tests if
available, and checks if signing/verification works with a test vector
from the IETF EdDSA draft.

The unit tests include a new testcase that will fuzz donna against ref0,
including the blinding and curve25519 key conversion routines.  If this
is something that should be done at runtime (No?), the code can be
stolen from there.

Note: Integrating batch verification is not done yet.

optimized implementation vs known values from the NaCl documentation.

--connections n       makes n test connections per client (1)
--hs-multi-client 1   makes each client connect to each HS (0)

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.

RFC 952 is approximately 30 years old, and people are failing to comply,

the check is a QOL improvement for our userbase, relax the check to
allow such abominations as destinations, especially since there are
likely to be other similarly misconfigured domains out there.

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.

Fixes bug 16400.  Thanks to torkeln for reporting and
cypherpunks_backup for diagnosing and writing the first fix here.

2b27ce52d2 Fix out-of-bounds read in INTRODUCE2 client auth
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.

Fixes #15823; bugfix on 0.2.1.6-alpha.

6f6881c432 Use a random count of INTRODUCE2 for IP rotation
An introduction point is currently rotated when the amount of INTRODUCE2
cells reached a fixed value of 16384. This makes it pretty easy for an
attacker to inflate that number and observe when the IP rotates which leaks
the popularity of the HS (amount of client that passed through the IP).

This commit makes it a random count between the current value of 16384 and
two times that.

Fixes #15745

192ed94410 Use PTHREAD_CREATE_DETACHED macro instead of 1: fix Solaris crash
When calling pthread_attr_setdetachstate, we were using 1 as the
argument. But the pthreads documentation says that you have to say
PTHREAD_CREATE_DETACH, which on Solaris is apparently 0x40.  Calling
pthread_attr_setdetachstate with 1 crashes on Solaris with FLTBOUNDS.

(Because we're so late in the release cycle, I made the code define
PTHREAD_CREATE_DETACHED if it doesn't exist, so we aren't likely to
break any other platforms.)

This bug was introduced when we made threading mandatory in
0.2.6.1-alpha; previously, we had force-disabled threading on
Solaris.  See #9495 discussion.

0c11d8b2d2 Implement status/fresh-relay-descs command
The idea here is that a controller should be able to make Tor produce a

uploaded to the dirauths (they would likely reject it anyway due to
freshness concerns).

44abbf5ab6 Dropping test_cmdline_args.py
Before a couple weeks ago didn't know Tor had these tests, interesting! Stem
already has tests for spawning tor processes but lacked any with this targeted
focus on its arguments.

I've added our own counterpart for these tests. Many are direct copies but
there were others I improved a little...

  https://trac.torproject.org/projects/tor/ticket/14109
  https://gitweb.torproject.org/stem.git/commit/?id=137d193a026638f066e817e3396cebbbb6ace012

Now that Tor uses Stem to supplement its tests no reason for these to live
separately. Tested by simply building tor and confirming test_cmdline_args.py
is no longer in the generated Makefile.

51f793e37e Fix possible infinite loop on pipe/sock_drain()
If the returned value of read/recv is 0 (meaning EOF), we'll end up in an
infinite loop (active wait) until something is written on the pipe which is
not really what we want here especially because those functions are called
from the main thread.

b5525476f5 Fix: close intro circuit if no more intro points are usable
Once a NACK is received on the intro circuit, tor tries an other usable one
by extending the current circuit to it. If no more intro points are usable,
now close the circuit. Also, it's reason is changed before closing it so we
don't report again an intro point failure and trigger an extra HS fetch.

fcc78e5f8a Use package-config output for -lsystemd correctly
In systemd 209, they deprecated -lsystemd-daemon in favor of
-lsystemd.  So we'd better actually look at the pkg-config output,
or we'll get warnings on newer distributions.

For some as-yet-unknown-to-me reason, setting CFLAGS so early makes
it so -O2 -g doesn't get added to it later.  So, adding it myself
later.  Perhaps a better fix here can be found.

Fixes 14072; bugfix on 0.2.6.2-alpha.  Based on a patch from h.venev

b06b783fa0 Tolerate relative paths for torrc files with RunAsDaemon
We had a check to block these, but the patch we merged as a1c1fc72
broke this check by making them absolute on demand every time we
opened them.  That's not so great though. Instead, we should make them
absolute on startup, and not let them change after that.

8ef6cdc39f Prevent changes to other options from removing . from AutomapHostsSuffixes
This happened because we changed AutomapHostsSuffixes to replace "."
with "", since a suffix of "" means "match everything."  But our
option handling code for CSV options likes to remove empty entries
when it re-parses stuff.

Instead, let "." remain ".", and treat it specially when we're
checking for a match.

74cd57517c New option "HiddenServiceAllowUnknownPorts"
This allows hidden services to disable the anti-scanning feature
introduced in 0.2.6.2-alpha. With this option not set, a connection
to an unlisted port closes the circuit.  With this option set, only
a RELAY_DONE cell is sent.

2b8e1f9133 Fix Reachability self-tests in test networks
Stop assuming that private addresses are local when checking
reachability in a TestingTorNetwork. Instead, when testing, assume
all OR connections are remote. (This is necessary due to many test
scenarios running all nodes on localhost.)

This assists in bootstrapping a testing Tor network.

c3a4201faa Add "internal" to some bootstrap statuses when no exits are available.
If the consensus does not contain Exits, Tor will only build internal
circuits. In this case, relevant statuses will contain the word "internal"
as indicated in the Tor control-spec.txt. When bootstrap completes,
Tor will be ready to handle an application requesting an internal
circuit to hidden services at ".onion" addresses.

If a future consensus contains Exits, exit circuits may become available.

Tor already notifies the user at "notice" level if they have no exits in
the consensus, and can therefor only build internal paths.

Consequential change from #13718.

cb94f7534d Avoid building exit circuits from a consensus with no exits
Tor can now build circuits from a consensus with no exits.
But if it tries to build exit circuits, they fail and flood the logs.

The circuit types in the Exit Circuits list below will only be
built if the current consensus has exits. If it doesn't,
only the Internal Circuits will be built. (This can change
with each new consensus.)
Fixes bug #13814, causes fewer path failures due to #13817.

Exit Circuits:
    Predicted Exit Circuits
    User Traffic Circuits
    Most AP Streams
    Circuits Marked Exit
    Build Timeout Circuits (with exits)

Internal Circuits:
    Hidden Service Server Circuits
    Hidden Service Client Circuits
    Hidden Service AP Streams
    Hidden Service Intro Point Streams
    Circuits Marked Internal
    Build Timeout Circuits (with no exits)
    Other Circuits?

55ad54e014 Allow tor to build circuits using a consensus with no exits
If the consensus has no exits (typical of a bootstrapping
test network), allow tor to build circuits once enough
descriptors have been downloaded.

When there are no exits, we always have "enough"
exit descriptors. (We treat the proportion of available
exit descriptors as 100%.)

This assists in bootstrapping a testing Tor network.

Fixes bug 13718.

Add router_have_consensus_path() which reports whether

argument readability in nodelist.c.

22a1e9cac1 Avoid excluding guards from path building in minimal test networks
choose_good_entry_server() now excludes current entry
guards and their families, unless we're in a test network,
and excluding guards would exclude all nodes.

This typically occurs in incredibly small tor networks,
and those using TestingAuthVoteGuard *

This is an incomplete fix, but is no worse than the previous
behaviour, and only applies to minimal, testing tor networks
(so it's no less secure).

Discovered as part of #13718.

88901c3967 Fix: mitigate as much as we can HS port scanning
Make hidden service port scanning harder by sending back REASON_DONE which
does not disclose that it was in fact an exit policy issue. After that, kill
the circuit immediately to avoid more bad requests on it.

This means that everytime an hidden service exit policy does match, the user
(malicious or not) needs to build a new circuit.

Fixes #13667.
