c442d85439 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, and to forward-port it to
0.2.4.

Clients now consider the ClientRejectInternalAddresses config option
when using a microdescriptor consensus stanza to decide whether
an exit relay would allow exiting to an internal address. Fixes

85659d3964 Fix parse_short_policy (bug 7192.) 
Our implementation of parse_short_policy was screwed up: it would
ignore the last character of every short policy.  Obviously, that's
broken.

This patch fixes the busted behavior, and adds a bunch of unit tests
to make sure the rest of that function is okay.

Fixes bug 7192; fix on 0.2.3.1-alpha.

86258df65d Merge branch 'split_circuitbuild' 
Conflicts:
	src/or/circuitbuild.c

There was a huge-looking conflict in circuitbuild.c, but the only
change that had been made to circuitbuild.c since I forked off the
split_circuitbuild branch was 17442560c4.  So I took the
split_circuitbuild version of the conflicting part, and manually
re-applied the change from 17442560c44e8093f9a..

26946c659b Restore the 'address' value of tunneled connections 
When we merged the channel code, we made the 'address' field of linked
directory connections created with begindir (and their associated edge
connections) contain an address:port string, when they should only
have contained the address part.

This patch also tweaks the interface to the get_descr method of
channels so that it takes a set of flags rather than a single flag.

field of an exit connection used in making a tunneled directory
request.  Turns out that wasn't right.

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:

0cb921f3e9 Convert all include-guard macros to avoid reserved identifiers. 
In C, we technically aren't supposed to define our own things that
start with an underscore.

This is a purely machine-generated commit.  First, I ran this script
on all the headers in src/{common,or,test,tools/*}/*.h :
==============================

use strict;

my %macros = ();
my %skipped = ();
FILE: for my $fn (@ARGV) {
    my $f = $fn;
    if ($fn !~ /^\.\//) {
	$f = "./$fn";
    }
    $skipped{$fn} = 0;
    open(F, $fn);
    while (<F>) {
	if (/^#ifndef ([A-Za-z0-9_]+)/) {
	    $macros{$fn} = $1;
	    next FILE;
	}
    }
}

print "#!/usr/bin/perl -w -i -p\n\n";
for my $fn (@ARGV) {
    if (! exists $macros{$fn}) {
	print "# No macro known for $fn!\n" if (!$skipped{$fn});
	next;
    }
    if ($macros{$fn} !~ /_H_?$/) {
	print "# Weird macro for $fn...\n";
    }
    my $goodmacro = uc $fn;
    $goodmacro =~ s#.*/##;
    $goodmacro =~ s#[\/\-\.]#_#g;
    print "s/(?<![A-Za-z0-9_])$macros{$fn}(?![A-Za-z0-9_])/TOR_${goodmacro}/g;\n"
}
==============================

It produced the following output, which I then re-ran on those same files:

7ea904cbc0 Merge branch 'bug7011' 
Conflicts:
	src/or/circuitbuild.c

The conflict was trivial, since no line of code actually changed in
both branches: There was a fmt_addr() that turned into fmt_addrport()
in bug7011, and a "if (!n_conn)" that turned into "if (!n_chan)" in
master.

8419d18441 Use fmt_addrport where appropriate. 
This is mostly a conversion from this pattern:
	log("... %s:%d ...", fmt_and_decorate_addr(&addr), port);
to this:
	log("... %s ...", fmt_addrport(&addr, port));

The output is the same in all cases.

4b0a039cb8 Use fmt_and_decorate_addr in extra-info "transport" lines. 
Apparently BridgeDB is already expecting transport lines to be formatted
thus; see https://trac.torproject.org/projects/tor/ticket/7011#comment:12 ff.
It may be that there are no extant IPv6 pluggable transport bridges yet,
so this didn't cause a problem.

5cbf0f2106 Use fmt_and_decorate_addr in TransportProxy statefile entry. 
state_transport_line_is_valid calls tor_addr_port_lookup, which expects
brackets around an IPv6 address. Without this, cached transport
addresses can't be parsed later:

[warn] state: Could not parse addrport.
[warn] state: State file seems to be broken.

See #7011.

41328c7009 Decorate addresses given to a HTTP CONNECT proxy. 
This affects the Request-URI and the value of the Host header. RFC 2616
doesn't directly address the formatting of IPv6 addresses, but it
delegates some productions to RFC 2396 "Uniform Resource Identifiers
(URI): Generic Syntax," which is obsoleted by RFC 3986, which requires
square brackets for IPv6 addresses in both places.

I tested this with
	HTTPSProxy 127.0.0.1:8000
	Bridge <IPv6 bridge>
	UseBridges 1
and an Ncat HTTP proxy:
	ncat --proxy-type http -l 8000 -vvv
