If PoW are enabled, use a priority queue by effort for the rendezvous
requests hooked into the mainloop.

At this commit, the tor main loop solves it. We might consider moving
this to the CPU pool at some point.

This adds a `reason` label to the `hs_intro_rejected_intro_req_count` and
`hs_rdv_error_count` metrics introduced in #40755.
Metric look up and intialization is now more a bit more involved. This may be
fine for now, but it will become unwieldy if/when we add more labels (and as
such will need to be refactored).
Also, in the future, we may want to introduce finer grained `reason` labels.
For example, the `invalid_introduce2` label actually covers multiple types of
errors that can happen during the processing of an INTRODUCE2 cell (such as
cell parse errors, replays, decryption errors).

This introduces a couple of new service side metrics:
* `hs_intro_rejected_intro_req_count`, which counts the number of introduction
requests rejected by the hidden service
* `hs_rdv_error_count`, which counts the number of rendezvous errors as seen by
the hidden service (this number includes the number of circuit establishment
failures, failed retries, end-to-end circuit setup failures)
Closes #40755. This partially addresses #40717.

Turns out that passing client authorization keys to ADD_ONION for v3 was
not working because we were not setting the "is_client_auth_enabled"
flag to true once the clients were configured. This lead to the
descriptor being encoded without the clients.
This patch removes that flag and instead adds an inline function that
can be used to check if a given service has client authorization
enabled.
This will be much less error prone of needing to keep in sync the client
list and a flag instead.
Fixes #40378

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.

Some days before this commit, the network experienced a DDoS on the directory
authorities that prevented them to generate a consensus for more than 5 hours
straight.
That in turn entirely disabled onion service v3, client and service side, due
to the subsystem requiring a live consensus to function properly.
We know require a reasonably live consensus which means that the HSv3
subsystem will to its job for using the best consensus tor can find. If the
entire network is using an old consensus, than this should be alright.
If the service happens to use a live consensus while a client is not, it
should still work because the client will use the current SRV it sees which
might be the previous SRV for the service for which it still publish
descriptors for.
If the service is using an old one and somehow can't get a new one while
clients are on a new one, then reachability issues might arise. However, this
is a situation we already have at the moment since the service will simply not
work if it doesn't have a live consensus while a client has one.
Fixes #40237

Typos found with codespell.
Please keep in mind that this should have impact on actual code
and must be carefully evaluated:

- ctf_enum_value("CONTROLER", CIRCUIT_PURPOSE_CONTROLLER)
+ ctf_enum_value("CONTROLLER", CIRCUIT_PURPOSE_CONTROLLER)

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.

It's more natural there since it's runtime state.
|
|
When a service can not upload its descriptor(s), we have no logs on why. This
adds logging for each possible reason for each descriptors.
That logging is emitted every second so it is rate limited for each reason and
per descriptor.
Closes #33400

Only use the HS circuit map to know if an introduction circuit is established
or not. No need for a flag to keep state of something we already have in the
circuit map. Furthermore, the circuit map gets cleaned up properly so it will
always have the "latest truth".
This commit also removes a unit test that was testing specifically that flag
but now we rely solely on the HS circuit map which is also tested few lines
below the removed test.

The right way to free a config object is now to wrap config_free(),
always. Instead of creating an alternative free function, objects
should provide an alternative clear callback to free any fields that
the configuration manager doesn't manage.
This lets us simplify our code a little, and lets us extend the
confparse.c code to manage additional fields in config_free.

Coverity is worried that we check "service" at the end of these test
functions, since it doesn't see any way to reach the cleanup code
without having first dereferenced the variable.
Removing the check would be unwise in this case: instead we add a
tt_assert check before using "service" so that coverity thinks that
the check is doing something useful.
Bugfix on 0.3.2.1-alpha.

This should fix about 15 CID issues, where coverity can't tell that
hs_free_all() frees the service we allocated.

We are using an opaque pointer so the structure needs to be allocated on the
heap. This means we now need a constructor for crypt_path_t.
Also modify all places initializing a crypt_path_t to use the constructor.

The previous commits for 23576 confused hs_desc_link_specifier_t
and link_specifier_t. Removing hs_desc_link_specifier_t fixes this
confusion.

Rewrite service_intro_point_new() to take a node_t. Since
node_get_link_specifier_smartlist() supports IPv6 link specifiers,
this refactor adds IPv6 addresses to onion service descriptors.
