fd07872a72 Separate failure-count tracking from circuit-launching. 
Increment failure counts only when circuits close without having been built.
Reset failure counts only on the second, and when circuits are done building.

9a676b04dd Check that we can write to the logfile and log a warning to stderr if we can't 
Move writing of pidfile after daemonizing, and also after setting the [ug]id:
This means that the tor user needs write priviliges to the pidfile location.
It needs it for unlinking the pidfile anyway.

bugfix: only try circuit_n_conn_open if we're an OP. Otherwise we
        expect connections to always already be up.
bugfix: when choosing path length, pay attention to whether the directory
        says a router is down.

        (more work needs to be done on this one)

a8eaa79e03 Improved exit policy syntax; basic client-side DNS caching. 
- Exit policies now support bitmasks (18.0.0.0/255.0.0.0) and bitcounts
  18.0.0.0/8.  Policies are parsed on startup, not when comparing to them.

- desired_path_len is now part of an opaque cpath_build_state_t structure.

- END_REASON_EXITPOLICY cells no longer include a port.

- RELAY_COMMAND_CONNECTED cells now include the IP address we've connected
  to.

- connection_edge now has a client_dns cache to remember resolved addresses.
  It gets populated by RELAY_COMMAND_CONNECTED cells and END_REASON_EXITPOLICY
  cells.  It gets used by connection_ap_handshake_send_begin.  We don't
  compare it to exit policies yet.

7604cfe61b Clock skew fixes. 
Allow some slop (currently 3 minutes) when checking certificate validity.

Change certificate lifetime from 1 year to 2 days.  Since we
regenerate regularly (we regenerate regularly, right??), this
shouldn't be a problem.

Have directories reject descriptors published too far in the future
(currently 30 minutes).  If dirservs don't do this:
    0) Today is January 1, 2000.
    1) A very skewed server publishes descriptor X with a declared
       publication time of August 1, 2000.
    2) The directory includes X.
    3) Because of certificate lifetime issues, nobody can use the
       skewed server.
    4) The server fixes its skew, and goes to republish a new descriptor Y
       with publication time of January 1, 2000.
    5) But because the directory already has a "more recent" descriptor X,
       it rejects descriptor "Y" as superseded!

This patch should make step 2 go away.

4139c1c86a - fixed a bug in the id switching code -- setgid has to happen before 
setuid, because after we setuid we don't have the priviledges we
  need to setgid anymore, duh.  merged switch_user() and
  switch_group() into switch_id(), since that code has to be wound
  together.

- return -1 from switch_id() if it's not defined to do anything else.

- moved daemoinize(), write_pidfile(), and switch_id() from main.c to
  util.c

b1eca56b77 added User and Group options -- if you set them, tor will try to 
setuid and setgid respectively, and die if it can't.

(If the User option is set, tor will setgid to the user's gid as well.)

This happens after the pidfile is created, so that in cases where tor
needs to be root to work with the pidfile, it will at least be able to
create it, although it won't be able to delete it.  That sucks, but
it's somewhat better than not being able to create the pidfile in the
first place.

4a66865d0b send the end cell when we realize we're going to end, 
not when we're closing the stream.

this lets us put a payload in the end cell if we want to,
to describe why we're closing the stream.

there are still some places where we don't send the end cell
immediately. i need to track them down. but it's a low priority,
since i've made it send the end cell when we close the stream if
we haven't already sent it.

Improve debugging output on fingerprint checking.

Make sure to add our own fingerprint to the fingerprint list _before_
adding our own descriptor, or else we'll reject ourself.

Don't call a directory invalid just because we have a newer descriptor
for some router.

Use router_get_dir_hash to generate hashes for signed directories.

Make sure we add our own descriptor successfully.

Don't fall-through on failed base64-endode.

9e5cafc395 first pass: obey log convention 
ERR is if something fatal just happened

WARNING is something bad happened, but we're still running. The bad thing
is either a bug in the code, an attack or buggy protocol/implementation
of the remote peer, etc. The operator should examine the bad thing and
try to correct it.
(No error or warning messages should be expected. I expect most people
to run on -l warning eventually.)

NOTICE is never ever used.

INFO means something happened (maybe bad, maybe ok), but there's nothing
you need to (or can) do about it.

DEBUG is for everything louder than INFO.

3d4ccb781a Refactor buffers; implement descriptors. 
'buf_t' is now an opaque type defined in buffers.c .

Router descriptors now include all keys; routers generate keys as
needed on startup (in a newly defined "data directory"), and generate
their own descriptors.  Descriptors are now self-signed.

Implementation is not complete: descriptors are never published; and
upon receiving a descriptor, the directory doesn't do anything with
it.

At least "routers.or" and orkeygen are now obsolete, BTW.

40d0fca63a cleanups, bugfixes, more verbose logs 
Fixed up the assert_*_ok funcs some (more work remains)

Changed config so it reads either /etc/torrc or the -f arg, never both

Finally tracked down a nasty bug with our use of tls:
  It turns out that if you ask SSL_read() for no more than n bytes, it
  will read the entire record from the network (and maybe part of the next
  record, I'm not sure), give you n bytes of it, and keep the remaining
  bytes internally. This is fine, except our poll-for-read looks at the
  network, and there are no bytes pending on the network, so we never know
  to ask SSL_read() for more bytes. Currently I've hacked it so if we ask
  for n bytes and it returns n bytes, then it reads again right then. This
  will interact poorly with our rate limiting; we need a cleaner solution.

- 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.

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.

2147898577 Implemented router twins 
I modified new_route so we don't pick twins back-to-back in the path.

I also had to patch my previous uses of connection_twin_get_by_addr_port()
because they assumed that "addr" and "port" would be the same for a twin
as for the original router.

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.

ccdef66b68 new link padding scheme 
we're now much more robust when bandwidth varies: instead of forcing a
fixed bandwidth on the link, we instead use what the link will give us,
up to our bandwidth.

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.

0a3da3ae37 put in the support for 'router twins' 
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
the routers config file.

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.

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 ;)
