9016d9e829 Add an IPv6Exit configuration option
Don't advertise an IPv6 exit policy, or accept IPv6 exit requests,
if IPv6Exit is not true.

c3faa0ebd5 Simplest version of server-side IPv6 support (no dns)
This is a relatively simple set of changes: we mostly need to
remove a few "but not for IPv6" changes.  We also needed to tweak
the handling of DNS code to generate RESOLVED cells that could get
an IPv6 answer in return.

462ebb270a Refactor begin cell parsing into its own function, with tests.
Add 'flags' argument to begin cells, per proposal 208.

ca8843df0a Refactor client_dns_set_{reverse_,}addressmap() to take a circ
We'd like these functions to be circuit-relative so that we can
implement a per-circuit DNS cache and per-circuit DNS cache rules for
proposal 205 or its successors.  I'm doing this now, as a part of the
IPv6 exits code, since there are about to be a few more instances
of code using this.

49dd5ef3a3 Add and use and unlikely-to-be-eliminated memwipe()
Apparently some compilers like to eliminate memset() operations on
data that's about to go out-of-scope.  I've gone with the safest
possible replacement, which might be a bit slow.  I don't think this
is critical path in any way that will affect performance, but if it
is, we can work on that in 0.2.4.

Fixes bug 7352.

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.

898bd1ae8f Fix for bug 7112 (spewing complaints from tor_addr_is_internal)
In 4768c0efe3 (not in any released
version of Tor), we removed a little block of code that set the addr
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:

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.

7faf115dff Change all SMARTLIST_FOREACH loops of >=10 lines to use BEGIN/END
The SMARTLIST_FOREACH macro is more convenient than BEGIN/END when
you have a nice short loop body, but using it for long bodies makes
your preprocessor tell the compiler that all the code is on the same
line.  That causes grief, since compiler warnings and debugger lines
will all refer to that one line.

So, here's a new style rule: SMARTLIST_FOREACH blocks need to be
short.

c239c57d3c Fix a regression bug in AllowDotExit
The code that detected the source of a remapped address checked that
an address mapping's source was a given rewrite rule if addr_orig had
no .exit, and addr did have a .exit after processing that rule.  But
addr_orig was formatted for logging: it was not the original address
at all, but rather was the address escaped for logging and possibly
replaced with "[scrubbed]".

This new logic will correctly set ADDRMAPSRC_NONE in the case when the
address starts life as a .exit address, so that AllowDotExit can work
again.

35d08e30d8 An attempt at bug3940 and making AllowDotExit 0 work with MapAddress
This time, I follow grarpamp's suggestion and move the check for
.exit+AllowDotExit 0 to the top of connection_ap_rewrite_and_attach,
before any rewriting occurs.  This way, .exit addresses are
forbidden as they arrive from a socks connection or a DNSPort
request, and not otherwise.

It _is_ a little more complicated than that, though.  We need to
treat any .exit addresses whose source is TrackHostExits as meaning
that we can retry without that exit.  We also need to treat any
.exit address that comes from an AutomapHostsOnResolve operation as
user-provided (and thus forbidden if AllowDotExits==0), so that
transitioning from AllowDotExits==1 to AllowDotExits==0 will
actually turn off automapped .exit addresses.

9c29369a04 Convert instances of tor_malloc+tor_snprintf into tor_asprintf
These were found by looking for tor_snprintf() instances that were
preceeded closely by tor_malloc(), though I probably converted some
more snprintfs as well.

(In every case, make sure that the length variable (if any) is
removed, renamed, or lowered, so that anything else that might have
assumed a longer buffer doesn't exist.)

as a map from a domain to itself, and would have cleared the mapping.

69d16900aa Refactor addressmap_match_superdomains and representation of wildcards
In this new representation for wildcarded addresses, there are no
longer any 'magic addresses': rather, "a.b c.d", "*.a.b c.d" and
"*.a.b *.c.d" are all represented by a mapping from "a.b" to "c.d". we
now distinguish them by setting bits in the addressmap_entry_t
structure, where src_wildcard is set if the source address had a
wildcard, and dst_wildcard is set if the target address had a
wildcard.

This lets the case where "*.a.b *.c.d" or "*.a.b c.d" remap the
address "a.b" get handled trivially, and lets us simplify and improve
the addressmap_match_superdomains implementation: we can now have it
run in O(parts of address) rather than O(entries in addressmap).

1. Only allow '*.' in MapAddress expressions. Ignore '*ample.com' and '.example.com'.
       This has resulted in a slight refactoring of config_register_addressmaps.
    2. Add some more detail to the man page entry for AddressMap.
    3. Fix initialization of a pointer to NULL rather than 0.
    4. Update the unit tests to cater for the changes in 1 and test more explicitly for
       recursive mapping.

1. Implement the following mapping rules:

   MapAddress a.b.c d.e.f # This is what we have now
   MapAddress .a.b.c d.e.f # Replaces any address ending with .a.b.c with d.e.f
   MapAddress .a.b.c .d.e.f # Replaces the .a.b.c at the end of any addr with .d.e.f

   (Note that 'a.b.c .d.e.f' is invalid, and will be rejected.)

2. Add tests for the new rules.

3. Allow proper wildcard annotation, i.e. '*.d.e' '.d.e' will still work.

4. Update addressmap_entry_t with an is_wildcard member.
