 * ADD new /src/common/crypto_util.[ch] module (contains the memwipe()
   function, since all crypto_* modules need this).

93ebcc2b8f rephist: Stop tracking relay connection status
Remove a series of connection counters that were only used when dumping the
rephist statistics with SIGUSR1 signal.

This reduces the or_history_t structure size.

e05414d241 Fix several places where md-using relays would get wrong behavior.
This patch replaces a few calls to router_get_by_id_digest ("do we
have a routerinfo?") with connection_or_digest_is_known_relay ("do
we know this relay to be in the consensus, or have been there some
time recently?").

Found while doing the 21585 audit; fixes bug 23533.  Bugfix on
0.3.0.1-alpha.

rephist: Remove unused crypto_pk statistics.
These statistics were largely ununsed, and kept track of statistical information
on things like how many time we had done TLS or how many signatures we had
verified.  This information is largely not useful, and would only be logged
after receiving a SIGUSR1 signal (but only if the logging severity level was
less than LOG_INFO).

 * FIXES #19871.
 * REMOVES note_crypto_pk_op(), dump_pk_op(), and pk_op_counts from
   src/or/rephist.c.
 * REMOVES every external call to these functions.

d5a151a067 Bug 17592: Clean up connection timeout logic.
This unifies CircuitIdleTimeout and PredictedCircsRelevanceTime into a single
option, and randomizes it.

It also gives us control over the default value as well as relay-to-relay
connection lifespan through the consensus.

b0e92634d8 Netflow record collapsing defense.
This defense will cause Cisco, Juniper, Fortinet, and other routers operating
in the default configuration to collapse netflow records that would normally
be split due to the 15 second flow idle timeout.

Collapsing these records should greatly reduce the utility of default netflow
data for correlation attacks, since all client-side records should become 30
minute chunks of total bytes sent/received, rather than creating multiple
separate records for every webpage load/ssh command interaction/XMPP chat/whatever
else happens to be inactive for more than 15 seconds.

The defense adds consensus parameters to govern the range of timeout values
for sending padding packets, as well as for keeping connections open.

The defense only sends padding when connections are otherwise inactive, and it
does not pad connections used solely for directory traffic at all. By default
it also doesn't pad inter-relay connections.

Statistics on the total padding in the last 24 hours are exported to the
extra-info descriptors.

aae034d13e Write a bunch of module documentation.
This commit adds or improves the module-level documenation for:

  buffers.c circuitstats.c command.c connection_edge.c control.c
  cpuworker.c crypto_curve25519.c crypto_curve25519.h
  crypto_ed25519.c crypto_format.c dircollate.c dirserv.c dns.c
  dns_structs.h fp_pair.c geoip.c hibernate.c keypin.c ntmain.c
  onion.c onion_fast.c onion_ntor.c onion_tap.c periodic.c
  protover.c protover.h reasons.c rephist.c replaycache.c
  routerlist.c routerparse.c routerset.c statefile.c status.c
  tor_main.c workqueue.c

In particular, I've tried to explain (for each documented module)
what each module does, what's in it, what the big idea is, why it
belongs in Tor, and who calls it.  In a few cases, I've added TODO
notes about refactoring opportunities.

I've also renamed an argument, and fixed a few DOCDOC comments.

4f1a04ff9c Replace nearly all XXX0vv comments with smarter ones
So, back long ago, XXX012 meant, "before Tor 0.1.2 is released, we
had better revisit this comment and fix it!"

But we have a huge pile of such comments accumulated for a large
number of released versions!  Not cool.

So, here's what I tried to do:

  * 0.2.9 and 0.2.8 are retained, since those are not yet released.

  * XXX+ or XXX++ or XXX++++ or whatever means, "This one looks
    quite important!"

  * The others, after one-by-one examination, are downgraded to
    plain old XXX.  Which doesn't mean they aren't a problem -- just
    that they cannot possibly be a release-blocking problem.

a885271c08 Add new tor_assert_nonfatal*() macros.
Unlike tor_assert(), these macros don't abort the process.  They're
good for checking conditions we want to warn about, but which don't
warrant a full crash.

This commit also changes the default implementation for
tor_fragile_assert() to tor_assert_nonfatal_unreached_once().

Closes ticket 18613.

91ab2ac5aa Assert that memory held by rephist is freed
The internal memory allocation and history object counters of the
reputation code can be used to verify the correctness of (part of) the
code. Using these counters revealed an issue where the memory allocation
counter is not decreased when the bandwidth arrays are freed.

A new function ensures the memory allocation counter is decreased when a
bandwidth array is freed.

This commit also removes an unnecessary cast which was found while
working on the code.
