0878ceb779 remove bandwidth negotation from the code
we still use bandwidth on a per-connection basis for rate
limiting. but it's unclear if we need this infrastructure in
addition to the total-bandwidth rate limiting that we also do.

i'll leave both infrastructures in, and we'll remove the
per-connection one if it starts rotting too much.

c336c99e60 Start of port to win32. Missing are:
- signal support
  - forking for DNS farm
  - changes for async IO
  - daemonizing

In other words, some files still don't build, and the ones that do build,
do nonblocking IO incorrectly.

I'm also not checking in the project files till I have a good place
for them.

f12fdd62aa Be smarter about getting key matter from DH.
Formerly, once we had g^xy, we took the last N bytes from g^xy.

Now, we take SHA(g^xy || [0]) || SHA1(g^xy || [1]) || ... , in order
to use all bits from g^xy equally, and generate as much key material
as we need.

22df330f14 Get directories working.
Or at least, directories get generated, signed, download, and checked, with
nobody seeming to crash.

In config/*, added 'signing-key' blocks to dirservers and routers.or, so
that everyone will know about the directories' signing keys.

In or/directory.c, refrained from using a dirserver's signing key when
no such key is known; added more debugging output.

In or/main.c, added debugging output and fixed a few logic errors.

In or/routers.c, added debugging output and prevented a segfault on
routers_resolve_directory.  The interleaving of arrays and lists on
routerinfo_t is still messy, but at least it seems to work again.

c35373a2cf major overhaul: dns slave subsystem, topics
on startup, it forks off a master dns handler, which forks off dns
slaves (like the apache model). slaves as spawned as load increases,
and then reused. excess slaves are not ever killed, currently.

implemented topics. each topic has a receive window in each direction
at each edge of the circuit, and sends sendme's at the data level, as
per before. each circuit also has receive windows in each direction at
each hop; an edge sends a circuit-level sendme as soon as enough data
cells have arrived (regardless of whether the data cells were flushed
to the exit conns). removed the 'connected' cell type, since it's now
a topic command within data cells.

at the edge of the circuit, there can be multiple connections associated
with a single circuit. you find them via the linked list conn->next_topic.

currently each new ap connection starts its own circuit, so we ought
to see comparable performance to what we had before. but that's only
because i haven't written the code to reattach to old circuits. please
try to break it as-is, and then i'll make it reuse the same circuit and
we'll try to break that.

Roger Dingledine
267434bdea Implemented congestion control
Servers are allowed to send 100 cells initially, and can't send more until
they receive a 'sendme' cell from that direction, indicating that they
can send 10 more cells. As it currently stands, the exit node quickly
runs out of window, and sends bursts of 10 whenever a sendme cell gets
to him. This is much much much faster (and more flexible) than the old
"give each circuit 1 kB/s and hope nothing overflows" approach.

Also divided out the connection_watch_events into stop_reading,
start_writing, etc. That way we can control them separately.

Roger Dingledine
117cbeeaaf Implemented link padding and receiver token buckets
Each socket reads at most 'bandwidth' bytes per second sustained, but
can handle bursts of up to 10*bandwidth bytes.

Cells are now sent out at evenly-spaced intervals, with padding sent
out otherwise. Set Linkpadding=0 in the rc file to send cells as soon
as they're available (and to never send padding cells).

Added license/copyrights statements at the top of most files.

router->min and router->max have been merged into a single 'bandwidth'
value. We should make the routerinfo_t reflect this (want to do that,
Mat?)

As the bandwidth increases, and we want to stop sleeping more and more
frequently to send a single cell, cpu usage goes up. At 128kB/s we're
pretty much calling poll with a timeout of 1ms or even 0ms. The current
code takes a timeout of 0-9ms and makes it 10ms. prepare_for_poll()
handles everything that should have happened in the past, so as long as
our buffers don't get too full in that 10ms, we're ok.

Speaking of too full, if you run three servers at 100kB/s with -l debug,
it spends too much time printing debugging messages to be able to keep
up with the cells. The outbuf ultimately fills up and it kills that
connection. If you run with -l err, it works fine up through 500kB/s and
probably beyond. Down the road we'll want to teach it to recognize when
an outbuf is getting full, and back off.

basically, a twin is a router which is different except it shares
the same keypair. so in cases where we want to find a "next router"
and all we really care is that it can decrypt the next onion layer,
then a twin is just as good.

we still need to decide how to mark twins in the routerinfo_t and in

builds now that i've removed common/onion.[ch] (oops)

d982925593 Integrated onion proxy into or/
The 'or' process can now be told (by the global_role variable) what
roles this server should play -- connect to all ORs, listen for ORs,
listen for OPs, listen for APs, or any combination.

* everything in /src/op/ is now obsolete.
* connection_ap.c now handles all interactions with application proxies
* "port" is now or_port, op_port, ap_port. But routers are still always
  referenced (say, in conn_get_by_addr_port()) by addr / or_port. We
  should make routers.c actually read these new ports (currently I've
  kludged it so op_port = or_port+10, ap_port=or_port+20)
* circuits currently know if they're at the beginning of the path because
  circ->cpath is set. They use this instead for crypts (both ways),
  if it's set.
* I still obey the "send a 0 back to the AP when you're ready" protocol,
  but I think we should phase it out. I can simply not read from the AP
  socket until I'm ready.

I need to do a lot of cleanup work here, but the code appears to work, so
now's a good time for a checkin.

Note that there are new keywords in these, etc. Matej, would you be
interested in going through and patching routers.c, config.c, etc, so
they're cleaner?

bd627daa40 First cut at cleaning out a lot of the extra stuff.
The summary here is that I'm requiring all developers to have
auto* (aclocal, autoconf, automake) installed on their machine.

Since different versions of auto* generate vastly different output,
I'm going to leave its output out of the repository. This means that
whenever you check out a repository, you need to run auto* to generate
a configure file, then run ./configure to get a Makefile, then build.

If you don't have auto* and can't get it, let me know (and I'll try to
convince you to develop on moria).

The benefit here is that while developers have a bit more work to keep
things straight, we can build snapshots that will install just about
anywhere (once we make configure.in work, that is ;)
