730dd9a6d0 Remove trailing semicolon from #define TOR_ADDR_NULL.
Can it ever help? I can only see harm. What am I missing?

d827a5495a Take microdesc into account when deciding about preferred OR port. 2012-09-04 12:57:22 -04:00
Linus Nordberg
8b081231b5 Make node_ipv6_preferred() take microdescs into account.
Also, make node_get_prim_orport() indicate in its return value whether
a valid OR port was copied or not.

Maybe we should make it legal to pass ap_out==NULL?

3746215350 Take microdesc IPv6 address into account when setting node->ipv6_preferred.
Also, do this only for clients, explicitly.

Also, give the flag a value every time we set consensus. We used to
touch it only when ClientPreferIPv6ORPort was set, which was wrong.

0f45dbefed Use preferred OR for nodes with routerstatus and microdesc too.
extend_info_from_node() used to use the primary OR port (i.e. IPv4)
unless the node had routerinfo. Now that we have IPv6 addresses in
microdescs we may want to use them.

Note that this patch changes using r->cache_info.identity_digest into
using node->identity. I count on these being well synchronised, or
things would break in other ways. Right?

e04e1a2e7d Clients connect to public relays over IPv6.
Add ClientUseIPv6 and ClientPreferIPv6ORPort configuration options.

Use "preferred OR port" for all entry nodes, not only for bridges.

Mark bridges with "prefer IPv6 OR port" if an IPv6 address is
configured in Bridge line and ClientPreferIPv6ORPort is set.

Mark relays with "prefer IPv6 OR port" if an IPv6 address is found in
descriptor and ClientPreferIPv6ORPort is set.

Filter "preferred OR port" through the ClientUseIPv6 config option. We
might want to move this test to where actual connection is being set
up once we have a fall back mechanism in place.

Have only non-servers pick an IPv6 address for the first hop: We
don't want relays to connect over IPv6 yet. (IPv6 has never been used
for second or third hops.)

Implements ticket 5535.

d6ad00a01f Clear the ipv6_preferred flag like the others.
I'm not entirely sure that this is meningful but I'm pretty sure it's
not harmful. Seems like the logical thing to do.

68901da5a1 Generate microdescriptors with "a" lines.
Generate and store all supported microdescriptor formats. Generate
votes with one "m" line for each format. Only "m" lines with version
info matching chosen consensus method will be voted upon.

An optimisation would be to combine "m" lines with identical hashes,
i.e. instead of "m 1,2,3 H1" and "m 4,5 H1", say "m 1,2,3,4,5 H1".

156ffef249 Have directory authorities vote on IPv6 OR ports according to the spec
Define new new consensus method 14 adding "a" lines to vote and
consensus documents.

From proposal 186:

  As with other data in the vote derived from the descriptor, the
  consensus will include whichever set of "a" lines are given by the
  most authorities who voted for the descriptor digest that will be
  used for the router.

This patch implements this.

eb3d079667 Make begindir_cutoff the same as general_cutoff
Allow one-hop directory fetching circuits the full "circuit build timeout"
period, rather than just half of it, before failing them and marking
the relay down. This fix should help reduce cases where clients declare
relays (or worse, bridges) unreachable because the TLS handshake takes
a few seconds to complete.

Fixes bug 6743 (one piece of bug 3443); bugfix on 0.2.2.2-alpha, where
we changed the timeout from a static 30 seconds.

b252ffa7cb Downgrade path-bias warning messages to INFO for now.
We've had over two months to fix them, and didn't.  Now we need
0.2.3.x stable.  Yes, it would be cool to get this working in
0.2.3.x, but not at the expense of delaying every other feature that
_does_ work in 0.2.3.x.  We can do a real fix in 0.2.4.

b7c172c9ec Disable extending to private/internal addresses by default
This is important, since otherwise an attacker can use timing info
to probe the internal network.

Also, add an option (ExtendAllowPrivateAddresses) so that
TestingTorNetwork won't break.
