Regular relays are about to get their DirPort removed so that reachability
test is not useful anymore
Authorities will still use the DirPort but because network reentry towards
their DirPort is now denied network wide, this test is not useful anymore and
so it should simply be considered reachable at all time.

This is unfortunately massive but both functionalities were extremely
intertwined and it would have required us to actually change the HSv2 code in
order to be able to split this into multiple commits.
After this commit, there are still artefacts of v2 in the code but there is no
more support for service, intro point and HSDir.
The v2 support for rendezvous circuit is still available since that code is
the same for the v3 and we will leave it in so if a client is able to
rendezvous on v2 then it can still transfer traffic. Once the entire network
has moved away from v2, we can remove v2 rendezvous point support.

Now that exit relays don't allow exit connections to directory authority
DirPorts, the follow-up step is to make directory authorities stop doing
DirPort reachability checks.

Typos found with codespell.
Please keep in mind that this should have impact on actual code
and must be carefully evaluated:
src/core/or/lttng_circuit.inc
- ctf_enum_value("CONTROLER", CIRCUIT_PURPOSE_CONTROLLER)
+ ctf_enum_value("CONTROLLER", CIRCUIT_PURPOSE_CONTROLLER)

(Unlike approaches in earlier versions of Tor, this one logs if and
only if we are launching a test, and we haven't said that we're
testing this port.)
Fixes bug 40068; bug not in any released version.
Closes #40068.

On an IPv6 reachability failure test, if the address was configured, don't
publish the descriptor and log warn. If the address was auto discovered, still
publish the descriptor.
Closes #33247.

This changes a LOT of code but in the end, behavior is the same.
Unfortunately, many functions had to be changed to accomodate but in majority
of cases, to become simpler.
Functions are also removed specifically those that were there to convert an
IPv4 as a host format to a tor_addr_t. Those are not needed anymore.
The IPv4 address field has been standardized to "ipv4_addr", the ORPort to
"ipv4_orport" (currently IPv6 uses ipv6_orport) and DirPort to "ipv4_dirport".
This is related to Sponsor 55 work that adds IPv6 support for relays and this
work is needed in order to have a common interface between IPv4 and IPv6.
Closes #40043.

In practice, there will be at most one ipv4 address and ipv6 address
for now, but this code is designed to not care which address is
which until forced to do so.
This patch does not yet actually create extend_info_t objects with
multiple addresses.
Closes #34069.

This is in response to a question about why we don't always log
orport self-tests as reachability tests.
I'm not 100% convinced that bandwidth self-tests are still useful,
but that's an issue for another day. :)

Previously we had two chains of logic for reachability tests: one
for launching them, and one for telling the user that we had
launched them. Now, we simply have the launch code inform the user:
this way, we can't get out of sync.
Closes ticket 34137.

This option tells Tor that our IPv6 orport is reachable, and doesn't
need to be checked.
Closes the rest of 33224.

This was supposed to happen in #40012, but the command line was wrong.
This is an automated commit, generated by this command:

These identifiers are confusing and unreadable. I think these
replacements should be better. Closes ticket #40012.

The '!=' checks were confusing the issue of what the code was really
doing.
|
|
I've managed to keep this change mainly contained to our
self-testing module. The changes here are:
* There are two different variables for tracking "is our orport
reachable".
* We have a new function that says whether we can skip a single
family's orport reachability test; the old function for this now
tells whether we can skip _all_ orport reachability testing.
(The name, router_should_skip_orport_reachability_test, is not
so good. I will rename it later if I can think of a good
replacement.)
* The function that launches orport reachability tests now only
launches the ones that haven't completed.
* The function that notes that we're reachable on an ORPort now
takes a family.
* Various log messages are cleaned up.

But don't implement the actual node selection yet.

Rewrite inform_testing_reachability() to use separate buffers for IPv4
ORPort, IPv6 ORPort, and IPv4 DirPort. And use consistent APIs to fill
those buffers.

When a relay starts testing reachability, log its IPv6 ORPort.
The existing code logs the IPv4 ORPort and DirPort.
The IPv4 ORPort is required. The other ports are only logged if they
are present.
