The `test-operator-cleanup` patch, and related coccinelle patches,
don't do any checks for line length. This patch fixes the line
length issues caused by the previous commits.
This patch fixes the operator usage in src/test/*.c to use the symbolic
operators instead of the normal C comparison operators.
This patch was generated using:
./scripts/coccinelle/test-operator-cleanup src/test/*.[ch]
This patch adds a script written by Nick for bug #13172 to clean up the
usage of ==, !=, <, >, <=, and >= by replacing them with their symbolic
OP_* counterpart. This will ensure that a tool like Coccinelle doesn't
get confused and silently ignore large blocks of code.
A client can re-extend up to 3 intro points on the same circuit. This happens
when we get NACKed by the intro point for which we choose a new intro and
re-extend the circuit to it.
That process can be arbitrarly long so reset the dirty timestamp of the
circuit everytime we choose to re-extend so we get a bit more time to actually
do our introduction.
This is a client circuit so it is short live once opened thus giving us a bit
more time to complete the introduction is ok.

When looking for an introduction circuit in circuit_get_best(), we log an info
message if we are about to launch a new intro circuit in parallel. However,
the condition was considering marked for close circuit leading to the function
triggering the log info even though there is actually no valid intro circuit.

Only register the RP circuit when it opens and not when we send the INTRODUCE1
cell else, when re-extending to a new IP, we would register the same RP
circuit with the same cookie twice leading to the circuit being closed.

Changed the assert_intro_circ_ok() to an almost non fatal function so tor can
recover properly. We keep the anonymity assert because if that is not right,
we have much deeper problems and client should stop sending bytes to the
network immediately.

This function has been replaced by hs_client_receive_rendezvous_acked(() doing
the same exact thing for both v2 and v3 service.

The client needs to find the right intro point object from the circuit
identity digest it is opened to. This new function does that.

New function named hs_cell_introduce1_data_clear() is introduced to clear off
an hs_cell_introduce1_data_t object.

When a client decodes a descriptor, make sure it matches the expected blinded
key which is derived from the hidden service identity key.

We can't trigger a valid upload because it would require us to MOCK a long
list of functions ultimately not really testing the upload because we aren't
on a running network.

Needed by the client when fetching a descriptor. This function checks the
directory purpose and hard assert if it is not for fetching.

This commit makes the client use the intro point state cache. It notes down
when we get a NACK from the intro point and then uses that cache to decide if
it should either close the circuits or re-extend to a new intro point.
This also introduces a very useful function that checks if an intro point is
usable that is query the state cache and checks a series of requirement.

This cache keeps track of the state of intro points which is needed when we
have failures when using them. It is similar to the failure cache of the
legacy system.
At this commit, it is unused but initialized, cleanup and freed.

This moves it to hs_client.c so it can be used by both system (legacy and
prop224). For now, only the legacy system uses it.

Don't assert() on rend_data when closing circuits to report an IP failure. The
prop224 code doesn't have yet the support for this.
Signed-off-by: David Goulet <dgoulet@torproject.org>
For now, prop224 doesn't have a mechanism to note down connection attempts so
we only do it for legacy system using rend_data.

The client can now handle RENDEZVOUS2 cell when they arrive. This consolidate
both hidden service version in one function.

The client is now able to handle an INTRODUCE_ACK cell and do the appropriate
actions.
An intro point failure cache is missing and a way to close all intro point
that were launched in parallel. Some notes are in the comment for that.

Add a function to parse an INTRODUCE_ACK cell in hs_cell.c. Furthermore, add
an enum that lists all possible expected status code.

From an edge connection object, add a function that randomly pick an
introduction point for the requested service.
This follows the code design of rend_client_get_random_intro() and returns an
extend_info_t object ready to be used to extend to.
At this commit, it is not used yet.

When a descriptor fetch has completed and it has been successfully stored in
the client cache, this callback will take appropriate actions to attach
streams and/or launch neede circuits to connect to the service.
