Add a missing lock acquisition around access to queued_control_events
in control_free_all(). Use the reassign-and-unlock strategy as in
queued_events_flush_all(). Fixes bug 25675. Coverity found this bug,
but only after we recently added an access to
flush_queued_event_pending.
There was a nonfatal assertion in pathbias_should_count that would
trigger if onehop_tunnel was set, but the desired_path_length was
greater than 1. This patch fixes that. Fixes bug 24903; bugfix on
0.2.5.2-alpha.
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.
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.

This makes the REPLICA= field optional for the control port event. A v2
service will always pass it and v3 is ignored.

A new v3 specific function has been added named
control_event_hsv3_descriptor_failed().
The HS v3 subsystem now uses it.

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.

Make control_event_hs_descriptor_received() and
control_event_hs_descriptor_failed() v2 specific because they take a
rend_data_t object and v3 will need to pass a different object.
No behavior change.

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.

This is a naming refactor mostly _except_ for a the events' function that take
a rend_data_t which will require much more refactoring.
No behavior change at this commit, cleanup and renaming stuff to not be only
v2 specific.

The functions are now used by the ADD_ONION/DEL_ONION control port command as
well. This commits makes them fully functionnal with hidden service v3.

Move it to hs_common.h and rename it "hs_service_add_ephemeral_status_t". It
will be shared between v2 and v3 services.

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.

On failure to upload, the HS_DESC event would report "UPLOAD_FAILED" as the
Action but it should have reported "FAILED" according to the spec.

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.
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.
Bug 23900.
