The memleak was occuring because of the way ExcludeNodes is handled in
that function. Basically, we were putting excluded intro points extend
infos in a special variable which was never freed. Also, if there were
multiple excluded intro points then that variable was overwritten
everytime leaking more memory. This commit should fix both issues.
This commit adds a pretty advanced test for the client-side making sure that
picking intro is done properly.
This unittest also reveals a memleak on the client_pick_intro() function which
is fixed by the subsequent commit.

Using a test vector in python, test both hs_build_hsdir_index() and
hs_build_hs_index().
This commit also adds the hs_build_address.py to EXTRA_DIST which was missing.

Do two major improvements:
a) Make the client pick 6 HSDirs instead of just 1 and make sure they
all match the service's HSDirs.
b) Test two additional missing scenarios borrowed from the
test_reachability() test.
Make download status next attempts reported over the control port
consistent with the time used by tor. This issue only occurs if a
download status has not been reset before it is queried over the
control port.
Fixes 23525, not in any released version of tor.
If future code asks if there are any running bridges, without checking
if bridges are enabled, log a BUG warning rather than crashing.
Fixes 23524 on 0.3.0.1-alpha
Change the contract of control_event_bootstrap_problem() to be more
general and to take a connection_t. New function
control_event_bootstrap_prob_or() has the specific or_connection_t
funcionality previously used.
Fix the test_build_address() test and its test vectors python script.
They were both using a bogus pubkey for building an HS address which
does not validate anymore.
Also fix a few more unittests that were using bogus onion addresses
and were failing the validation. I replaced the bogus address with
the one generated from the test vector script.
Directory servers now include a "Date:" http header for response
codes other than 200. Clients starting with a skewed clock and a
recent consensus were getting "304 Not modified" responses from
directory authorities, so without a Date header the client would
never hear about a wrong clock.
Fixes bug 23499; bugfix on 0.0.8rc1.
We enrich the test_client_cache() test in two ways:
a) We check that transitioning time periods also cleans up expired
descriptors in client memory.
b) We test hs_cache_lookup_as_client() instead of
lookup_v3_desc_as_client(). The former is a higher level function
which calls the latter and allows us to test deeper into the
subsystem.
In #23466 we discovered that cached descriptors can stay around on the
client-side for up to 72 hours. In reality we only want those descs to
get cached for the duration of the current time period, since after that
TP is gone the client needs to compute a new blinded key to use for the HS.
In this commit we start using the consensus time (if available) when
cleaning up cached client descriptor entries. That makes sense because
the client uses consensus time anyway for connecting to hidden
services (e.g. computing blinded keys and time periods).
If no recent consensus is available, we consider descriptors to be
expired since we will want to fetch new ones when we get a live
consensus to avoid the Roger bug. If we didn't do that, when Roger
desuspends his laptop there would be a race between Tor fetching a new
consensus, and Tor connecting to the HS which would still cause
reachability issues.
We also turned a rev counter check into a BUG, since we should never
receive a descriptor with a strictly smaller rev counter than the one we
already have, except if there is a bug or if the HSDir wants to mess
with us. In any case, let's turn this into a BUG so that we can detect
and debug such cases easily.
