We removed this documentation in 607724c696, when we removed
Naming Authoritative Directories, but actually this file is still
used by authorities to indicate rejected and invalid fingerprints.
Closes ticket 21148.
We used to not copy the state which means that after HUP we would forget
if we are in overlap mode or not. That caused bugs where the service
would enter overlap mode twice, and rotate its descs twice, causing all
sorts of bugs.
Apart from the fact that a newly allocated service doesn't have descriptors
thus the move condition can never be true, the service needs the descriptor
signing key to cross-certify the authentication key of each intro point so we
need to move the descriptors between services and not only the intro points.
Fixes#23056

We refactor the descriptor reupload logic to be similar to the v2 logic
where we update a global 'consider_republishing_rend_descriptors' flag
and then we use that to check for hash ring changes during the global
hidden service callbacks.
This fixes bugs where we would inspect the hash ring immediately as we
receive new dirinfo (e.g. consensus) but before running the hidden
service housekeeping events. That was leaving us in an inconsistent
state wrt hsdir indices and causing bugs all around.
The problem was that when we went from overlap mode to non-overlap mode,
we were not wiping the 'desc_next' descriptor and instead we left it on
the service. This meant that all functions that iterated service
descriptors were also inspecting the useless 'desc_next' descriptor that
should have been deleted.
This commit refactors rotate_all_descriptors() so that it rotates
descriptor both when entering overlap mode and also when leaving it.
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.
