Directory authorities no longer vote in favor of the Guard flag
for relays that don't advertise directory support.
Starting in Tor 0.3.0.1-alpha, Tor clients have been avoiding using
such relays in the Guard position, leading to increasingly broken load
balancing for the 5%-or-so of Guards that don't advertise directory
support.
Fixes bug 22310; bugfix on 0.3.0.6.

Coverity found a null pointer reference in nodelist_add_microdesc().
This is almost certainly impossible assuming that the routerstatus_t
returned by router_get_consensus_status_by_descriptor_digest() always
corresponds to an entry in the nodelist. Fixes bug 25629.

If we failed to connect at the TCP level to a relay, note it down and refuse
to connect again for another 60 seconds.

This update is needed to make it consistent with the behavior of
node_awaiting_ipv6(), which doesn't believe in the addresses from
routerinfos unless it actually plans to use those routerinfos.
Fixes bug 25213; bugfix on b66b62fb7525cac1e1 in 0.3.3.1-alpha,
which tightened up the definition of node_awaiting_ipv6().

There was a nonfatal assertion in pathbias_should_count that would
trigger if onehop_tunnel was set, but the desired_path_length was
greater than 1. This patch fixes that. Fixes bug 24903; bugfix on
0.2.5.2-alpha.

Make sure we actually only report client channel to the geoip cache instead of
looking if it is a known relay. Looking if it is a known relay can be
unreliable because they come and go from the consensus.

Because of #25306 for which we are unable to reproduce nor understand how it
is possible, this commit removes the asserts() and BUG() on the missing
descriptors instead when rotating them.
This allows us to log more data on error but also to let tor recover
gracefully instead of dying.

Apparently, sometimes getpwnam will call this.
Fixes bug 25513.

This patch adds some additional logging to circuits_handle_oom() to give
us more information about which specific compression backend that is
using a certain amount of memory.

It didn't like me insulting my patch, I guess.

This should avoid most intermittent test failures on developer and CI machines,
but there could (and probably should) be a more elegant solution.
Also, this test was testing that the IP was created and its expiration time was
set to a time greater than or equal to `now+INTRO_POINT_LIFETIME_MIN_SECONDS+5`:
/* Time to expire MUST also be in that range. We add 5 seconds because
* there could be a gap between setting now and the time taken in
* service_intro_point_new. On ARM, it can be surprisingly slow... */
tt_u64_op(ip->time_to_expire, OP_GE,
now + INTRO_POINT_LIFETIME_MIN_SECONDS + 5);
However, this appears to be a typo, since, according to the comment above it,
adding five seconds was done because the IP creation can be slow on some
systems. But the five seconds is added to the *minimum* time we're comparing
against, and so it actually functions to make this test *more* likely to fail on
slower systems. (It should either subtract five seconds, or instead add it to
time_to_expire.)

The C code and the rust code had different separate integer overflow
bugs here. That suggests that we're better off just forbidding this
pathological case.
Also, add tests for expected behavior on receiving a bad protocol
list in a consensus.
Fixes another part of 25249.

This one can only be exploited if you can generate a correctly
signed consensus, so it's not as bad as 25074.
Fixes bug 25251; also tracked as TROVE-2018-004.

In some cases we had checked for it, but in others we had not. One
of these cases could have been used to remotely cause
denial-of-service against directory authorities while they attempted
to vote.
