83743d64ab Change version parsing logic: a version is "obsolete" if it is not recommended and (1) there is a newer recommended version in the same series, or (2) there are no recommended versions in the same series, but there are some recommended versions in a newer series. A version is "new" if it is newer than any recommended version in the same series.

c1dc17e6e2 put in initial support for ".nickname.exit" addresses, to let alice 
decide what exit node to use; based on a patch by geoff goodell.

needs more work: e.g. it goes bananas building new circuits when the
chosen exit node's exit policy rejects the connection.

d381aa4696 Fix an evil bug: when we failed to write to our log, fputs() 
gave us a sigpipe, and we logged that we were ignoring it,
causing us to fail to log that, and delete the log entry. Then
when the signal handler exited, we proceeded to delete the log
entry that had already been deleted.

Now we make sure to only log inside our signal handler if we'll
be exit()ing right after.

a2517b4f07 checking only 0.0.7 and 0.0.8 didn't work, because some dirservers 
files have really old descriptors for the authdirservers, so we're
asking them in the new format because they're too old.

now we actually compare the version to a cutoff version, and act
appropriately.

also take this chance to use only >=0.0.8 servers for dns resolves,
because of the recent bugs. we'll bump to >=0.0.9pre1 once there are
some servers running that.

f6dbe5a0d4 Refactor crypto error handling to be more like TLS error handling: 
crypto_perror is a no-no, since an operation can set more than one
error.

Also, fix a bug in the unix crypto_seed_rng: mixing stdio with
/dev/urandom is a bad idea, since fopen can make all kinds of weird
extraneous syscalls (mmap, fcntl, stat64, etc.) and since fread tends
to buffer data in big chunks, thus depleting the entropy pool.

routerlist is routerinfo's that are bundled together in routers.c

preparing to break into router.c for stuff the router does,
and routerlist.c for handling routerlist.

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.

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.

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.

  - 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.
