This is needed for libressl-2.6.4 compatibility, which we broke when
we merged a15b2c57e1 to fix bug 19981. Fixes bug 26005; bug
not in any released Tor.
We cleared this value in second_elapsed_callback. But what were we
using it for? For detecting if Libevent returned EINVAL too often!
We already have a way to detect too-frequent events, and that's with
a ratelim_t. Refactor the code to use that instead. Closes ticket
26016.
Apart from adding the newly created Module.md, this commit also adds all the
missing files we have in HACKING/ to the EXTRA_DIST.

From Neel's latest patch on optimizing the hs_circ_service_get_intro_circ()
digest calculation, remove an extra white-space and clarify a comment of the
legacy key digest to inform when to use it.

This function must return false if the module is not compiled in. In order to
do that, we move the authdir_mode_v3() function out of router.c and into the
dirauth module new header file named mode.h.
It is always returning false if we don't have the module.
Closes#25990

This test was using the current time to pick the time period number,
and a randomly generated hs key. Therefore, it sometimes picked an
index that would wrap around the example dht, and sometimes would
not.
The fix here is just to fix the time period and the public key.
Fixes bug 25997; bugfix on 0.3.2.1-alpha.
When directory authorities read a zero-byte bandwidth file, they log
a warning with the contents of an uninitialised buffer. Log a warning
about the empty file instead.
Fixes bug 26007; bugfix on 0.2.2.1-alpha.
LibreSSL, despite not having the OpenSSL 1.1 API, does define
OPENSSL_VERSION in crypto.h. Additionally, it apparently annotates
some functions as returning NULL, so that our unit tests need to be
more careful about checking for NULL so they don't get compilation
warnings.
Closes ticket 26006.
This test, in test_client_pick_intro(), will have different coverage
depending on whether it selects a good intro point the first time or
whether it has to try a few times. Since it produces the shorter
coverage with P=1/4, repeat this test 64 times so that it only
provides reduced coverage with P=1/2^128. The performance cost is
negligible.
Closes ticket 25996. This test was introduced in 0.3.2.1-alpha.
I'd prefer not to do this for randomized tests, but as things stand
with this test, it produces nondeterministic test coverage.
Closes ticket 25995; bugfix on 0.2.2.2-alpha when this test was
introduced.
This change should make it impossible for the monotonic time to roll
over from one EWMA tick to the next during this test, and make it so
that this test never invokes scale_active_circuits() (which it
doesn't test).
(Earlier changes during the 0.3.4 series should make this call even
rarer than it was before, since we fixed#25927 and removed
cached_gettimeofday. Because this test didn't update
cached_gettimeofday, the chance of rolling over a 10-second interval
was much higher.)
Closes ticket 25994; bugfix on 0.3.3.1-alpha when this test was
introduced.
Arguably, the conditions under which these events happen should be a
bit different, but the rules are complex enough here that I've tried
to have this commit be pure refactoring.
Closes ticket 25952.
Finally, before this code goes away, take a moment to look at the
amazing way that we used to try to have an event happen
every N seconds:
get_uptime() / N != (get_uptime()+seconds_elapsed) / N
Truly, it is a thing of wonder. I'm glad we didn't start using this
pattern everywhere else.
