9328bd524e Enforce the rule that COMPRESS_OK means progress was made.
If COMPRESS_OK occurs but data is neither consumed nor generated,
treat it as a BUG and a COMPRESS_ERROR.

This change is meant to prevent infinite loops in the case where
we've made a mistake in one of our compression backends.

Closes ticket 22672.

5537e1fc45 If we successfully decompress an HTTP body, return immediately.
This prevents us from calling
allowed_anonymous_connection_compression_method() on the unused
guessed method (if any), and rejecting something that was already
safe to use.

d8cd68caf1 If a _guessed_ compression method fails, it is never PROTOCOL_WARN.
Rationale: When use a guessed compression method, we already gave a
PROTOCOL_WARN when our guess differed from the declared method,
AND we gave a PROTOCOL_WARN when the declared method failed.  It is
not a protocol problem that the guessed method failed too; it's just
a recovery attempt that failed.

7b3161f008 It should be a PROTOCOL_WARN when we have an incorrect content-encoding.
Rationale: The server did not obey the protocol, and its
content-encoding got munged. That's what PROTOCOL_WARN is for.

782eb02b79 Send the correct content-encoding when serving cached_dir_t objects
A cached_dir_t object (for now) is always compressed with
DEFLATE_METHOD, but in handle_get_status_vote() to we were using the
general compression-negotiation code decide what compression to
claim we were using.

This was one of the reasons behind 22502.

027614c263 Ensure that uint8_t is unsigned char
Many places in our code assume that uint8_t is the same type as
unsigned char.  Test this assumption in the configure script.  This is
important because of the privileged aliasing properties of character
types in C.

56a7c5bc15 TROVE-2017-005: Fix assertion failure in connection_edge_process_relay_cell
On an hidden service rendezvous circuit, a BEGIN_DIR could be sent
(maliciously) which would trigger a tor_assert() because
connection_edge_process_relay_cell() thought that the circuit is an
or_circuit_t but is an origin circuit in reality.

79b59a2dfc TROVE-2017-004: Fix assertion failure in relay_send_end_cell_from_edge_
This fixes an assertion failure in relay_send_end_cell_from_edge_() when an
origin circuit and a cpath_layer = NULL were passed.

A service rendezvous circuit could do such a thing when a malformed BEGIN cell
is received but shouldn't in the first place because the service needs to send
an END cell on the circuit for which it can not do without a cpath_layer.

34a6755b94 Fix ed25519 link certificate race on tls context rotation
Whenever we rotate our TLS context, we change our Ed25519
Signing->Link certificate.  But if we've already started a TLS
connection, then we've already sent the old X509 link certificate,
so the new Ed25519 Signing->Link certificate won't match it.

To fix this, we now store a copy of the Signing->Link certificate
when we initialize the handshake state, and send that certificate
as part of our CERTS cell.

a9be768959 Bugfix: Regenerate more certificates when appropriate
Previously we could sometimes change our signing key, but not
regenerate the certificates (signing->link and signing->auth) that
were signed with it.  Also, we would regularly replace our TLS x.509
link certificate (by rotating our TLS context) but not replace our
signing->link ed25519 certificate.  In both cases, the resulting
inconsistency would make other relays reject our link handshakes.

76c9330f9d Bug 17604: Converge on only one long-lived TLS conn between relays.
Accomplished via the following:

1. Use NETINFO cells to determine if both peers will agree on canonical
   status. Prefer connections where they agree to those where they do not.
2. Alter channel_is_better() to prefer older orconns in the case of multiple
   canonical connections, and use the orconn with more circuits on it in case
   of age ties.

Also perform some hourly accounting on how many of these types of connections
there are and log it at info or notice level.

b0e92634d8 Netflow record collapsing defense.
This defense will cause Cisco, Juniper, Fortinet, and other routers operating
in the default configuration to collapse netflow records that would normally
be split due to the 15 second flow idle timeout.

Collapsing these records should greatly reduce the utility of default netflow
data for correlation attacks, since all client-side records should become 30
minute chunks of total bytes sent/received, rather than creating multiple
separate records for every webpage load/ssh command interaction/XMPP chat/whatever
else happens to be inactive for more than 15 seconds.

The defense adds consensus parameters to govern the range of timeout values
for sending padding packets, as well as for keeping connections open.

The defense only sends padding when connections are otherwise inactive, and it
does not pad connections used solely for directory traffic at all. By default
it also doesn't pad inter-relay connections.

Statistics on the total padding in the last 24 hours are exported to the
extra-info descriptors.

db86b9194d Break connection_dir_client_reached_eof() into smaller functions
This was a >630-line function, which doesn't make anybody happy.  It
was also mostly composed of a bunch of if-statements that handled
different directory responses differently depending on the original
purpose of the directory connection.  The logical refactoring here
is to move the body of each switch statement into a separate handler
function, and to invoke those functions from a separate switch
statement.

This commit leaves whitespace mostly untouched, for ease of review.
I'll reindent in the next commit.

Inform the control port with an HS_DESC failed event when the client is unable

This commit adds the src/trace directory containing the basics for our tracing

The tracing subsystem can only be enabled by tracing framework at compile

4812441d34 Never read off the end of a buffer in base32_encode()
When we "fixed" #18280 in 4e4a7d2b0c
in 0291 it appears that we introduced a bug: The base32_encode
function can read off the end of the input buffer, if the input
buffer size modulo 5 is not equal to 0 or 3.

This is not completely horrible, for two reasons:
   * The extra bits that are read are never actually used: so this
     is only a crash when asan is enabled, in the worst case.  Not a
     data leak.

   * The input sizes passed to base32_encode are only ever multiples
      of 5. They are all either DIGEST_LEN (20), REND_SERVICE_ID_LEN
      (10), sizeof(rand_bytes) in addressmap.c (10), or an input in
      crypto.c that is forced to a multiple of 5.

So this bug can't actually trigger in today's Tor.

0fdad78fe1 cell: Do not warn on hidden service invalid port
When a client tried to connect to an invalid port of an hidden service, a
warning was printed:

  [warn] connection_edge_process_relay_cell (at origin) failed.

This is because the connection subsystem wants to close the circuit because
the port can't be found and then returns a negative reason to achieve that.
However, that specific situation triggered a warning. This commit prevents it
for the specific case of an invalid hidden service port.

Fixes #16706

ef4c10fb42 Fix max sampled size logic when in bridge mode.
When calculating max sampled size, Tor would only count the number of
bridges in torrc, without considering that our state file might already
have sampled bridges in it. This caused problems when people swap
bridges, since the following error would trigger:

44514058b9 Correctly handle fd-drain errors on windows workqueues
Windows doesn't let you check the socket error for a socket with
WSAGetLastError() and getsockopt(SO_ERROR).  But
getsockopt(SO_ERROR) clears the error on the socket, so you can't
call it more than once per error.

When we introduced recv_ni to help drain alert sockets, back in
0.2.6.3-alpha, we had the failure path for recv_ni call getsockopt()
twice, though: once to check for EINTR and one to check for EAGAIN.
Of course, we never got the eagain, so we treated it as an error,
and warned about: "No error".

The fix here is to have these functions return -errno on failure.

Fixes bug 21540; bugfix on 0.2.6.3-alpha.

Remove fgets() compatbility function and related tests.
This patch removes the `tor_fgets()` wrapper around `fgets(3)` since it
is no longer needed. The function was created due to inconsistency
between the returned values of `fgets(3)` on different versions of Unix
when using `fgets(3)` on non-blocking file descriptors, but with the
recent changes in bug #21654 we switch from unbuffered to direct I/O on
non-blocking file descriptors in our utility module.

We continue to use `fgets(3)` directly in the geoip and dirserv module
since this usage is considered safe.

This patch also removes the test-case that was created to detect
differences in the implementation of `fgets(3)` as well as the changes
file since these changes was not included in any releases yet.

reduce the use of the 'published' date even more.

`tor_fgets()` adds an additional check for whether the error-bit have
been enabled for the given file stream, if that is the case and `errno`
is set to `EAGAIN` we make sure that we always return NULL.

Unfortunately `fgets(3)` behaves differently on different versions of

18a98206ed Improve descriptor checks in the new guard algorithm.
- Make sure we check at least two guards for descriptor before making
  circuits. We typically use the first primary guard for circuits, but
  it can also happen that we use the second primary guard (e.g. if we
  pick our first primary guard as an exit), so we should make sure we
  have descriptors for both of them.

- Remove BUG() from the guard_has_descriptor() check since we now know
  that this can happen in rare but legitimate situations as well, and we
  should just move to the next guard in that case.

1582adabbb Change approach to preventing duplicate guards.
Previously I'd made a bad assumption in the implementation of
prop271 in 0.3.0.1-alpha: I'd assumed that there couldn't be two
guards with the same identity.  That's true for non-bridges, but in
the bridge case, we allow two bridges to have the same ID if they
have different addr:port combinations -- in order to have the same
bridge ID running multiple PTs.

Fortunately, this assumption wasn't deeply ingrained: we stop
enforcing the "one guard per ID" rule in the bridge case, and
instead enforce "one guard per <id,addr,port>".

We also needed to tweak our implementation of
get_bridge_info_for_guard, since it made the same incorrect
assumption.

4ed10e5053 hs: Fix bad use of sizeof() when encoding ESTABLISH_INTRO legacy cell
When encoding a legacy ESTABLISH_INTRO cell, we were using the sizeof() on a
pointer instead of using the real size of the destination buffer leading to an
overflow passing an enormous value to the signing digest function.
Fortunately, that value was only used to make sure the destination buffer
length was big enough for the key size and in this case it always was because
of the overflow.

auth_type is recognized (1 or 2), but not for any other non-zero

read.

Fixed by checking auth_len before comparing the descriptor cookie

19e25d5cab Prevention: never die from extend_info_from_node() failure.
Bug 21242 occurred because we asserted that extend_info_from_node()
had succeeded...even though we already had the code to handle such a
failure.  We fixed that in 93b39c5162.

But there were four other cases in our code where we called
extend_info_from_node() and either tor_assert()ed that it returned
non-NULL, or [in one case] silently assumed that it returned
non-NULL. That's not such a great idea.  This patch makes those
cases check for a bug of this kind instead.

Fixes bug 21372; bugfix on 0.2.3.1-alpha when
extend_info_from_node() was introduced.

This issue was triggered by 17027 in 0.2.8.1-alpha, which rejects a relay's
own IPv6 address.

Bugfix on commit 004f3f4e53 in 0.2.4.7-alpha.

51b562c605 Use an internal variable for HiddenServiceStatistics
Stop modifying the value of our torrc option HiddenServiceStatistics just
because we're not a bridge or relay. This bug was causing Tor Browser users to
write "HiddenServiceStatistics 0" in their torrc files as if they had chosen
to change the config.

4d83999213 Make "GETCONF SocksPort" work again
I broke "GETCONF *Port" in 20956, when I made SocksPort a
subordinate option of the virtual option SocksPortLines, so that I
could make SocksPort and __SocksPort provide qthe same
functionality.  The problem was that you can't pass a subordinate
option to GETCONF.

So, this patch fixes that by letting you fetch subordinate options.

It won't always be meaningful to consider these options
out-of-context, but that can be the controller-user's
responsibility to check.

Closes ticket 21300.

96c7ddbc7e circuit: Change close reasons from uint16_t to int
When marking for close a circuit, the reason value, a integer, was assigned to
a uint16_t converting any negative reasons (internal) to the wrong value. On
the HS side, this was causing the client to flag introduction points to be
unreachable as the internal reason was wrongfully converted to a positive
16bit value leading to flag 2 out of 3 intro points to be unreachable.

In the past, when we exhausted all guards in our sampled set, we just
waited there till we mark a guard for retry again (usually takes 10 mins
for a primary guard, 1 hour for a non-primary guard). This patch marks
all guards as maybe-reachable when we exhaust all guards (this can
happen when network is down for some time).

tor_addr_lookup() with a variant that always fails when it gets

04f21f0322 Remove abort handler from the backtrace generator
The abort handler masks the exit status of the backtrace generator by
capturing the abort signal from the backtrace handler and exiting with
zero. Because the output of the backtrace generator is meant to be piped
to `bt_test.py`, its exit status is unimportant and is currently
ignored.

The abort handler calls `exit(3)` which is not asynchronous-signal-safe
and calling it in this context is undefined behavior [0].
