3907faf2fd New accessors for keydir/cachedir access
This patch is a result of auditing all of our uses of
get_datadir_fname() and its kin, and dividing them into cache vs
keys vs other data.

The new get_keydir_fname() and get_cachedir_fname() functions don't
actually do anything new yet.

475d8d1a3d control: Don't check if Server is an HSDir for HSPOST
This is removed for two reasons. First, HSDir accepts descriptor even though
they don't think they are in fact an HSDir. This is to avoid consensus desync
between client/service and directories.

Second, our malicious HSDir scanner uses the HSPOST command to post on all
relays in order to test them before they could become HSDir. We had to remove
that check from the tor code that the scanner uses.

Thus, this check should not be enforced by the control port for the above use
cases. It is also a bit more complex with v3 support for which not all HSDir
support it so basically irrelevant check.

743d0b9d91 hs-v3: Implement HS_DESC REQUESTED event
This changes the control_event_hs_descriptor_requested() call to add the hsdir
index optional value. v2 passes NULL all the time.

This commit creates hs_control.{c|h} that contains wrappers for the HS
subsystem to interact with the control port subsystem.

The descriptor REQUESTED event is implemented following proposal 284 extension
for v3.

beacbbe210 control: Refactor control_event_hs_descriptor_receive_end
First, rename and make that function static because it is internal to
control.c and called by two HS_DESC events.

Second, make it take more basic parameters and thus not a rend_data_t object
so we can still use the function for v3 HS that doesn't use that object.

Third, move the descriptor ID lookup to the two specific events (yes little
code duplication there) because they get a rend_data_t object which won't be
the case for v3.

Finally, through this refactoring, change the pointer check to BUG() and
change some parameter names to reflect what they really are.

No behavior change at this commit.

49f21b6ba3 control: Support HSv3 interface for ADD_ONION
At this commit, the key handling and generation is supported for a v3 service
(ED25519-V3). However, the service creation is not yet implemented. This only
adds the interface and code to deal with the new ED25519-V3 key type.

Tests have been updated for RSA key type but nothing yet for ED25519-v3.

1df43aff41 Return instead of exiting in options_init_from_torrc() 2017-10-20 11:39:17 -04:00
Nick Mathewson
35746a9ee7 Comment-only change: annotate exit() calls.
Sometimes when we call exit(), it's because the process is
completely hopeless: openssl has a broken AES-CTR implementation, or
the clock is in the 1960s, or something like that.

But sometimes, we should return cleanly from tor_main() instead, so
that embedders can keep embedding us and start another Tor process.

I've gone through all the exit() and _exit() calls to annotate them
with "exit ok" or "XXXX bad exit" -- the next step will be to fix
the bad exit()s.

First step towards 23848.

f1bf9bf819 Add __OwningControllerFD to allow controllers without controlports
This feature should help programs that want to launch and manage a
Tor process, as well as programs that want to launch and manage a
Tor instance in a separate thread.  Right now, they have to open a
controlport, and then connect to it, with attendant authentication
issues.  This feature allows them to just start with an
authenticated connection.

4a7e90adc5 Repair buffer API so everything starts with buf_.

80d3887360 Refactor node lookup APIs to take flags
Right now there's a single warn_if_unnamed flag for
router_get_consensus_status_by_nickname() and
node_get_by_nickname(), that is nearly always 1.  I've turned it
into an 'unsigned' bitfield, and inverted its sense.  I've added the
flags argument to node_get_by_hex_id() too, though it does nothing
there right now.

I've removed the router_get_consensus_status_by_nickname() function,
since it was only used in once place.

This patch changes the warning behavior of GETINFO ns/name/<name>,
since all other name lookups from the controller currently warn.

Later I'm going to add more flags, for ed25519 support.

bce18a7642 prop224: Refactor parse_extended_hostname() to parse v3 addrs.
We need this func so that we recognize SOCKS conns to v3 addresses.

- Also rename rend_valid_service_id() to rend_valid_v2_service_id()

- Also move parse_extended_hostname() tests to their own unittest, and
  add a v3 address to the test as well.
