4ccf09b1c2 Reject create/begin/etc cells with {circ,stream}ID 0. 
Otherwise, it's possible to create streams or circuits with these
bogus IDs, leading to orphaned circuits or streams, or to ones that
can cause bandwidth DOS problems.

Fixes bug 7889; bugfix on all released Tors.

2802ccaeb6 Teach cpuworker and others about create_cell_t and friends 
The unit of work sent to a cpuworker is now a create_cell_t; its
response is now a created_cell_t.  Several of the things that call or
get called by this chain of logic now take create_cell_t or
created_cell_t too.

Since all cpuworkers are forked or spawned by Tor, they don't need a
stable wire protocol, so we can just send structs.  This saves us some
insanity, and helps p

f58d4dfcd6 Massive refactoring of the various handshake types 
The three handshake types are now accessed from a unified interface;
their state is abstracted from the rest of the cpath state, and so on.

f7e590df05 Split onion.[ch] into onion{,_fast,_tap}.[ch] 
I'm going to want a generic "onionskin" type and set of wrappers, and
for that, it will be helpful to isolate the different circuit creation
handshakes.  Now the original handshake is in onion_tap.[ch], the
CREATE_FAST handshake is in onion_fast.[ch], and onion.[ch] now
handles the onion queue.

This commit does nothing but move code and adjust header files.

bfffc1f0fc Allow a v4 link protocol for 4-byte circuit IDs. 
Implements proposal 214.

758428dd32 Fix a remotely triggerable assertion failure (CVE-2012-2250) 
If we completed the handshake for the v2 link protocol but wound up
negotiating the wong protocol version, we'd become so confused about
what part of the handshake we were in that we'd promptly die with an
assertion.

This is a fix for CVE-2012-2250; it's a bugfix on 0.2.3.6-alpha.
All servers running that version or later should really upgrade.

Bug and fix from "some guy from France."  I tweaked his code slightly
to make it log the IP of the offending node.

f357ef9dcc Discard extraneous renegotiation attempts in the v3 link protocol 
Failure to do so left us open to a remotely triggerable assertion
failure. Fixes CVE-2012-2249; bugfix on 0.2.3.6-alpha. Reported by
"some guy from France".

56c0baa523 Rename all reserved C identifiers we defined 
For everything we declare that starts with _, make it end with _ instead.

This is a machine-generated patch.  To make it, start by getting the
list of reserved identifiers using:

     git ls-tree -r --name-only HEAD | grep  '\.[ch]$' | \
       xargs ctags --c-kinds=defglmpstuvx -o - | grep '^_' | \
       cut -f 1 | sort| uniq

You might need gnu ctags.

Then pipe the output through this script:
==============================

use strict;

BEGIN { print "#!/usr/bin/perl -w -i -p\n\n"; }

chomp;

next if (
     /^__attribute__/ or
     /^__func__/ or
     /^_FILE_OFFSET_BITS/ or
     /^_FORTIFY_SOURCE/ or
     /^_GNU_SOURCE/ or
     /^_WIN32/ or
     /^_DARWIN_UNLIMITED/ or
     /^_FILE_OFFSET_BITS/ or
     /^_LARGEFILE64_SOURCE/ or
     /^_LFS64_LARGEFILE/ or
     /^__cdecl/ or
     /^__attribute__/ or
     /^__func__/ or
    /^_WIN32_WINNT/);

my $ident = $_;

my $better = $ident;
$better =~ s/^_//;

$better = "${better}_";

print "s/(?<![A-Za-z0-9_])$ident(?![A-Za-z0-9_])/$better/g;\n";
==============================

Then run the resulting script on all the files you want to change.
(That is, all the C except that in src/ext.)  The resulting script was:

Nick Mathewson
e56d7a3809 Give tor_cert_get_id_digests() fail-fast behavior 
Right now we can take the digests only of an RSA key, and only expect to
take the digests of an RSA key.  The old tor_cert_get_id_digests() would
return a good set of digests for an RSA key, and an all-zero one for a
non-RSA key.  This behavior is too error-prone: it carries the risk that
we will someday check two non-RSA keys for equality and conclude that
they must be equal because they both have the same (zero) "digest".

Instead, let's have tor_cert_get_id_digests() return NULL for keys we
can't handle, and make its callers explicitly test for NULL.

a5232e0c4c Fix GCC 4.6's new -Wunused-but-set-variable warnings. 
Most instances were dead code; for those, I removed the assignments.
Some were pieces of info we don't currently plan to use, but which
we might in the future.  For those, I added an explicit cast-to-void
to indicate that we know that the thing's unused.  Finally, one was
a case where we were testing the wrong variable in a unit test.
That one I fixed.

b95dd03e5f Log descriptions of nodes, not just nicknames. 
This patch introduces a few new functions in router.c to produce a
more helpful description of a node than its nickame, and then tweaks
nearly all log messages taking a nickname as an argument to call these
functions instead.

There are a few cases where I left the old log messages alone: in
these cases, the nickname was that of an authority (whose nicknames
are useful and unique), or the message already included an identity
and/or an address.  I might have missed a couple more too.

This is a fix for bug 3045.

26e897420e Initial conversion to use node_t throughout our codebase. 
A node_t is an abstraction over routerstatus_t, routerinfo_t, and
microdesc_t.  It should try to present a consistent interface to all
of them.  There should be a node_t for a server whenever there is
  * A routerinfo_t for it in the routerlist
  * A routerstatus_t in the current_consensus.
(note that a microdesc_t alone isn't enough to make a node_t exist,
since microdescriptors aren't usable on their own.)

There are three ways to get a node_t right now: looking it up by ID,
looking it up by nickname, and iterating over the whole list of
microdescriptors.

All (or nearly all) functions that are supposed to return "a router"
-- especially those used in building connections and circuits --
should return a node_t, not a routerinfo_t or a routerstatus_t.

A node_t should hold all the *mutable* flags about a node.  This
patch moves the is_foo flags from routerinfo_t into node_t.  The
flags in routerstatus_t remain, but they get set from the consensus
and should not change.

Some other highlights of this patch are:

  * Looking up routerinfo and routerstatus by nickname is now
    unified and based on the "look up a node by nickname" function.
    This tries to look only at the values from current consensus,
    and not get confused by the routerinfo_t->is_named flag, which
    could get set for other weird reasons.  This changes the
    behavior of how authorities (when acting as clients) deal with
    nodes that have been listed by nickname.

  * I tried not to artificially increase the size of the diff here
    by moving functions around.  As a result, some functions that
    now operate on nodes are now in the wrong file -- they should
    get moved to nodelist.c once this refactoring settles down.
    This moving should happen as part of a patch that moves
    functions AND NOTHING ELSE.

  * Some old code is now left around inside #if 0/1 blocks, and
    should get removed once I've verified that I don't want it
    sitting around to see how we used to do things.

There are still some unimplemented functions: these are flagged
with "UNIMPLEMENTED_NODELIST()."  I'll work on filling in the
implementation here, piece by piece.

I wish this patch could have been smaller, but there did not seem to
be any piece of it that was independent from the rest.  Moving flags
forces many functions that once returned routerinfo_t * to return
node_t *, which forces their friends to change, and so on.
