Jan 18 04:11:43.312 [warn] connection_edge_send_command(): no circ. Closing.

i think it was while sending a connected relay cell back.
reason for having the circ gone is still not known. presumably the end cell
arrived at just the right time.

c485725c5a Fix the dns bug: children weren't dying 
We were telling a child to die by closing the parent's file descriptor
to him. But newer children were inheriting the open file descriptor from
the parent, and since they weren't closing them, the socket never closed,
so the child never read eof, so he never knew to exit.

As a side effect to this bug, we were probably failing to properly close
connections to remote hosts, ORs, and OPs, after a dns child was born.

I'm surprised Tor worked at all.

when you get an 'end' cell that resolves an IP, now it will fail the                             circuit outright if no safe exit nodes exist for that IP.
don't try building a new circuit after an 'end' if a suitable one is
  already on the way.

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.

6b79d8a7e9 Two-pronged attack at my overzealous skew fixes. 
The problem was that the fixes had us generating TLS certs with a
2-day lifetime on the assumption that we'd rotate fairly often.  In
fact, we never rotate our TLS keys.

This patch fixes the situation in 2 ways:
   1. It bumps the default lifetime back up to one year until we get
      rotation in place.
   2. It changes tor_tls_context_new() so that it doesn't leak memory
      when you call it more than once.

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.

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,

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.

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.

078c5ab617 leave the socks handshake on the inbuf until it's complete 
this paves the way for supporting socks5 and other handshakes
it also removes those pesky AP-only variables from connection_t

also hacked a fix for a bug where some streams weren't ending properly --
maybe because marked connections weren't flushing properly?

them through stdio.  (It turns out (according to gprof) that logging
performance matters.)
