The DormantClientTimeout option controls how long Tor will wait before
going dormant. It also provides a way to disable the feature by setting
DormantClientTimeout to e.g. "50 years".
The DormantTimeoutDisabledByIdleStreams option controls whether open but
inactive streams count as "client activity". To implement it, I had to
make it so that reading or writing on a client stream *always* counts as
activity.
Closes ticket 28429.
Specifically, if the consensus is older than the (estimted or
measured) release date for this version of tor, we assume that the
required versions may have changed in between that consensus and
this release.
Implements ticket 27735 and proposal 297.
After we clear the protover map for getting full, we need to
re-create it, since we are about to use it.
This is a bugfix for bug 28558. It is a bugfix for the code from
ticket 27225, which is not in any released Tor. Found by Google
OSS-Fuzz, as issue 11475.
Our tests showed that this function is responsible for a huge number
of our malloc/free() calls. It's a prime candidate for being
memoized.
Closes ticket 27225.
When storing a descriptor in the client cache, if we are about to replace an
existing descriptor, make sure to close every introduction circuits of the old
descriptor so we don't have leftovers lying around.
Ticket 27471 describes a situation where tor is sending an INTRODUCE1 cell on
an introduction circuit for which it doesn't have a matching intro point
object (taken from the descriptor).
The main theory is that, after a new descriptor showed up, the introduction
points changed which led to selecting an introduction circuit not used by the
service anymore thus for which we are unable to find the corresponding
introduction point within the descriptor we just fetched.
Closes#27471.

It differs from the rest of the rephist code in that it's actually
necessary for Tor to operate, so it should probably go somewhere
else. I'm not sure where yet, so I'll leave it in the same
directory, but give it its own file.
The main.c code is responsible for initialization and shutdown;
the mainloop.c code is responsible for running the main loop of Tor.
Splitting the "generic event loop" part of mainloop.c from the
event-loop-specific part is not done as part of this patch.
The parts for handling cell formats should be in src/core/or.
The parts for handling onionskin queues should be in src/core/or.
Only the crypto wrapper belongs in src/core/crypto.
In dirauth:
* bwauth.c reads and uses bandwidth files
* guardfraction.c reads and uses the guardfraction file
* reachability.c tests relay reachability
* recommend_pkg.c handles the recommended-packages lines.
* recv_descs.c handles fingerprint files and processing incoming
routerinfos that relays upload to us
* voteflag.c computes flag thresholds and sets those thresholds on
routerstatuses when computing votes
In control:
* fmt_serverstatus.c generates the ancient "v1 server status"
format that controllers expect.
In nodelist:
* routerstatus_fmt.c formats routerstatus entries for a consensus,
a vote, or for the controller.
There are now separate modules for:
* the list of router descriptors
* the list of authorities and fallbacks
* managing authority certificates
* selecting random nodes
