cc52f7e5b7 Bug 40897 Bug Bounty: Double the number of max conflux circs 
We strongly suspect that bug 40897 was caused by a custom Tor client that
tried to use more than the default number of conflux circuits, for either
performance or traffic analysis defense gains, or both.

This entity hit a safety check on the exit side, which caused a UAF. Our
"belt and suspenders" snapped off, and hit us in the face... again...

Since there are good reasons to try more than 2 conflux legs, and research has
found some traffic analysis benefits with as many as 5, we're going to raise
and parameterize this limit as a form of bug bounty for finding this UAF, so
that this entity can try out a little more confluxing.

This should also make it easier for researchers to try things like gathering
traces with larger amounts of confluxing than normal, to measure real-world
traffic analysis impacts of conflux.

Shine on, you yoloing anonymous diamond. Let us know if you find out anything
interesting!

03778a0f34 Bug 40897: Add more checks to free paths 
Similar double-frees would be caught earlier by these, so long as the pointers
remain nulled out.

e62b8bce5a hs: Fix assert in hs_metrics_update_by_ident() 
The hs_metrics_failed_rdv() macro could pass a NULL value for the identity key
when a building circuit would end up in a failure path *before* the "hs_ident"
was able to be set which leading to this assert.

This was introduced in 0.4.8.1-alpha with the addition of rendezvous circuit
failure metrics for the MetricsPort.

This fixes TROVE-2023-006 for which its severity is considered high.
