50d777dcf4 Split directory_handle_command_get into subfunctions.
This was one of our longest functions, at 600 lines.  It makes a nice
table-driven URL-based function instead.

The code is a bit ugly, it leave the indentation as it is in hopes of
making pending directory.c changes easier to merge.  Later we can
clean up the indentation.

Also, remove unused mallinfo export code from directory.c

Switch between fallback and authority when auth cert fetch fails 2016-05-10 11:25:55 -04:00

Use the consensus download schedule for authority certificates
Previously, we were using the generic schedule for some downloads,
and the consensus schedule for others.

Resolves ticket 18816; fix on fddb814fe in 0.2.4.13-alpha.

be0e1e9e2f Stop being so strict about the payload length of "rendezvous1" cells
We used to be locked in to the "tap" handshake length, and now we can
handle better handshakes like "ntor".

Resolves ticket 18998.

I checked that relay_send_command_from_edge() behaves fine when you
hand it a payload with length 0. Clients behave fine too, since current
clients remain strict about the required length in the rendezvous2 cells.
(Clients will want to become less strict once they have an alternate
format that they're willing to receive.)

bcae392e0e avoid another redundant check
we should avoid launching a consensus fetch if we don't want one,
but if we do end up with an extra one, we should let the other checks
take care of it.

e230e80ab3 get rid of the scattered checks to cancel a consensus fetch
We'll back off from the request in connection_ap_handshake_attach_circuit,
or cancel it in connection_dir_close_consensus_fetches, and those are the
only places we need to check.

d5a23ce115 Move rend auth cookie en-/decoding to a function
Tor stores client authorization cookies in two slightly different forms.
The service's client_keys file has the standard base64-encoded cookie,
including two chars of padding. The hostname file and the client remove
the two padding chars, and store an auth type flag in the unused bits.

The distinction makes no sense. Refactor all decoding to use the same
function, which will accept either form, and use a helper function for
encoding the truncated format.

0cf90bac2a Choose the correct address for one-hop connections
After #17840 in 0.2.8.1-alpha, we incorrectly chose an IPv4
address for all DIRIND_ONEHOP directory connections,
even if the routerstatus didn't have an IPv4 address.

This likely affected bridge clients with IPv6 bridges.

Resolves #18921.

0ca3f495c6 Fix dnsserv.c assertion when no supported questions are requested.
The problem is that "q" is always set on the first iteration even
if the question is not a supported question. This set of "q" is
not necessary, and will be handled after exiting the loop if there
if a supported q->type was found.
