Each type of scheduler implements its own static scheduler_t object and
returns a reference to it.
This commit also makes it a const pointer that is it can only change inside
the scheduler type subsystem but not outside for extra protection.

This option is a list of possible scheduler type tor can use ordered by
priority. Its default value is "KIST,KISTLite,Vanilla" which means that KIST
will be used first and if unavailable will fallback to KISTLite and so on.

Wrap things in HAVE_KIST_SUPPORT until Tor compiles and tests cleanly on
my OS X machine.

- massive change to src/tgest/test_options.c since the sched options
were added all over the place in it
- removing the sched options caused some tests to pass/fail in new ways
so I assumed current behavior is correct and made them pass again
- ex: "ConnLimit must be greater" lines
- ex: "Authoritative directory servers must" line
- remove test_options_validate__scheduler in prep for new sched tests

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.

Valid intro points need both legacy key and ipv4.

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.

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.

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.

OpenBSD doesn't like tricks where you use a too-wide sscanf argument
for a too-narrow array, even when you know the input string
statically. The fix here is just to use bigger buffers.
Fixes 15582; bugfix on a3dafd3f58bb312 in 0.2.6.2-alpha.

17750 made unused download schedules automatically reset.
But we should make that explicit.
|
|
But when clients are just starting, make them try each bridge a few times
before giving up on it.
These changes make the bridge download schedules more explicit: before
17750, they relied on undocumented behaviour and specific schedule
entries. (And between 17750 and this fix, they were broken.)
Fixes 23347, not in any released version of tor.

This test is important because it tests that upload_descriptor_to_all()
is in synch with pick_hsdir_v3(). That's not the case for the
reachability test which just compares the responsible hsdir sets.

Because of the latest changes on when we rotate, longer lifetime of
descriptors and no more overlap period, the tests needed to be improved to
test more functionnalities.

First, this fixes #23372.
Second, the consensus timings for the build descriptor have been changed to
the current test can pass. More extensive tests of descriptor rotation are
coming in a commit near you because the rotation and time period logic has
been changed.

This is a large and important unit test for the hidden service version
3! It tests the service reachability for a client using different
consensus timings and makes sure that the computed hashring is the same
on both side so it is actually reachable.

With the latest change on how we use the HSDir index, the client and service
need to pick their responsible HSDir differently that is depending on if they
are before or after a new time period.
The overlap mode is active function has been renamed for this and test added.

Because of #23387, we've realized that there is one scenario that makes
the client unable to reach the service because of a desynch in the time
period used. The scenario is as follows:
+------------------------------------------------------------------+
| |
| 00:00 12:00 00:00 12:00 00:00 12:00 |
| SRV#1 TP#1 SRV#2 TP#2 SRV#3 TP#3 |
| |
| $==========|-----------$===========|-----------$===========| |
| ^ ^ |
| C S |
+------------------------------------------------------------------+
In this scenario the HS has a newer consensus than the client, and the
HS just moved to the next TP but the client is still stuck on the old
one. However, the service is not in any sort of overlap mode so it
doesn't cover the old TP anymore, so the client is unable to fetch a
descriptor.
We've decided to solve this by extending the concept of overlap period
to be permanent so that the service always publishes two descriptors and
aims to cover clients with both older and newer consensuses. See the
spec patch in #23387 for more details.
|
|
Based on our #23387 findings, it seems like to maintain 24/7
reachability we need to employ different logic when computing hsdir
indices for fetching vs storing. That's to guarantee that the client
will always fetch the current descriptor, while the service will always
publish two descriptors aiming to cover all possible edge cases.
For more details see the next commit and the spec branch.
