We used to do init_keys() if DynamicDHGroups changed after a HUP, so
that the dynamic DH modulus was stored on the disk. Since we are now
doing dynamic DH modulus storing in crypto.c, we can simply initialize
the TLS context and be good with it.
Introduce a new function router_initialize_tls_context() which
initializes the TLS context and use it appropriately.
Right now we only force a new descriptor upload every 18 hours.
This can make servers become unlisted if they upload a descriptor at
time T which the authorities reject as being "too similar" to one
they uploaded before. Nothing will actually make the server upload a
new descriptor later on, until another 18 hours have passed.
This patch changes the upload behavior so that the 18 hour interval
applies only when we're listed in a live consensus with a descriptor
published within the last 18 hours. Otherwise--if we're not listed
in the live consensus, or if we're listed with a publication time
over 18 hours in the past--we upload a new descriptor every 90
minutes.
This is an attempted bugfix for #3327. If we merge it, it should
obsolete #535.
This lets us make a lot of other stuff const, allows the compiler to
generate (slightly) better code, and will make me get slightly fewer
patches from folks who stick mutable stuff into or_options_t.
const: because not every input is an output!
options->DirPort is 0 in the unit tests, so
router_get_advertised_dir_port() would return 0 so we wouldn't pick a
dirport. This isn't what we want for the unit tests. Fixes bug
introduced in 95ac3ea594.
The conflicts were mainly caused by the routerinfo->node transition.

The comment fixes are trivial. The defensive programming trick is to
tolerate receiving NULL inputs on the describe functions. That should
never actually happen, but it seems like the likeliest mistake for us
to make in the future.
This patch introduces a few new functions in router.c to produce a
more helpful description of a node than its nickame, and then tweaks
nearly all log messages taking a nickname as an argument to call these
functions instead.
There are a few cases where I left the old log messages alone: in
these cases, the nickname was that of an authority (whose nicknames
are useful and unique), or the message already included an identity
and/or an address. I might have missed a couple more too.
This is a fix for bug 3045.
We'll eventually want to do more work here to make sure that the ports
are stable over multiple invocations. Otherwise, turning your node on
and off will get you a new DirPort/ORPort needlessly.
Our checks that we don't exceed the 50 KB size limit of extra-info
descriptors apparently failed. This patch fixes these checks and reserves
another 250 bytes for appending the signature. Fixes bug 2183.
The RefuseUnknownExits config option is now a tristate, with "1"
meaning "enable it no matter what the consensus says", "0" meaning
"disable it no matter what the consensus says", and "auto" meaning "do
what the consensus says". If the consensus is silent, we enable
RefuseUnknownExits.
This patch also changes the dirserv logic so that refuseunknownexits
won't make us cache unless we're an exit.
