Undeprecate it;
rename it to TestingClientDNSRejectInternalAddresses;
add the old name as an alias;
reject configurations where it is set but TestingTorNetwork is not;
change the documentation accordingly.

I'm doing this using the Proxy-Authorization: header to support
clients that understand it, and with a new tor-specific header that
makes more sense for our use.
Our convention is that functions which manipulate a type T should be
named T_foo. But the buffer functions were super old, and followed
all kinds of conventions. Now they're uniform.
Here's the perl I used to do this:
\#!/usr/bin/perl -w -i -p
s/read_to_buf\(/buf_read_from_socket\(/;
s/flush_buf\(/buf_flush_to_socket\(/;
s/read_to_buf_tls\(/buf_read_from_tls\(/;
s/flush_buf_tls\(/buf_flush_to_tls\(/;
s/write_to_buf\(/buf_add\(/;
s/write_to_buf_compress\(/buf_add_compress\(/;
s/move_buf_to_buf\(/buf_move_to_buf\(/;
s/peek_from_buf\(/buf_peek\(/;
s/fetch_from_buf\(/buf_get_bytes\(/;
s/fetch_from_buf_line\(/buf_get_line\(/;
s/fetch_from_buf_line\(/buf_get_line\(/;
s/buf_remove_from_front\(/buf_drain\(/;
s/peek_buf_startswith\(/buf_peek_startswith\(/;

For now, prop224 doesn't have a mechanism to note down connection attempts so
we only do it for legacy system using rend_data.

Right now there's a single warn_if_unnamed flag for
router_get_consensus_status_by_nickname() and
node_get_by_nickname(), that is nearly always 1. I've turned it
into an 'unsigned' bitfield, and inverted its sense. I've added the
flags argument to node_get_by_hex_id() too, though it does nothing
there right now.
I've removed the router_get_consensus_status_by_nickname() function,
since it was only used in once place.
This patch changes the warning behavior of GETINFO ns/name/<name>,
since all other name lookups from the controller currently warn.
Later I'm going to add more flags, for ed25519 support.
We will need to edit this function, and it's already pretty huge. Let's make
it a bit smaller.
This commit moves code, fixes a 80 char line and add two lines at the start to
make it compile. Trivial change.

We need this func so that we recognize SOCKS conns to v3 addresses.
- Also rename rend_valid_service_id() to rend_valid_v2_service_id()
- Also move parse_extended_hostname() tests to their own unittest, and
add a v3 address to the test as well.

Add a common function for both legacy and prop224 hidden service to increment
and decrement the rendezvous stream counter on an origin circuit.
Signed-off-by: David Goulet <dgoulet@torproject.org>
This commit refactors the handle_hs_exit_conn() function introduced at a prior
commit that connects the rendezvous circuit to the edge connection used to
connect to the service virtual port requested in a BEGIN cell.
The refactor adds the support for prop224 adding the
hs_service_set_conn_addr_port() function that has the same purpose has
rend_service_set_connection_addr_port() from the legacy code.
The rend_service_set_connection_addr_port() has also been a bit refactored so
the common code can be shared between the two HS subsystems (legacy and
prop224).
In terms of functionallity, nothing has changed, we still close the circuits
in case of failure for the same reasons as the legacy system currently does.

This commit simply moves the code from the if condition of a rendezvous
circuit to a function to handle such a connection. No code was modified
_except_ the use or rh.stream_id changed to n_stream->stream_id so we don't
have to pass the cell header to the function.
This is groundwork for prop224 support which will break down the
handle_hs_exit_conn() depending on the version of hidden service the circuit
and edge connection is for.

- Move some crypto structures so that they are visible by tests.
- Introduce a func to count number of hops in cpath which will be used
by the tests.
- Mark a function as mockable.
The legacy HS circuit code uses rend_data to match between circuits and
streams. We refactor some of that code so that it understands hs_ident
as well which is used for prop224.
This fixes an assertion failure in relay_send_end_cell_from_edge_() when an
origin circuit and a cpath_layer = NULL were passed.
A service rendezvous circuit could do such a thing when a malformed BEGIN cell
is received but shouldn't in the first place because the service needs to send
an END cell on the circuit for which it can not do without a cpath_layer.

Deprecated in 0.2.9.2-alpha, this commits changes it as OBSOLETE() and cleans

Partially fixes#22060
Signed-off-by: David Goulet <dgoulet@torproject.org>
This is a purely cosmetic patch that changes RELAY_BEGINDIR in various
comments to RELAY_BEGIN_DIR, which should make it easier to grep for the
symbols.
In order to help an HS operator knowing if the application configured behind
it is not working properly, add a log at warning level for the connection
refused or timeout case. This log will only be printed if a client connection
fails and is rate limited.

In order to implement proposal 224, we need the data structure rend_data_t to
be able to accomodate versionning that is the current version of hidden
service (2) and the new version (3) and future version.
For that, we implement a series of accessors and a downcast function to get
the v2 data structure. rend_data_t becomes a top level generic place holder.
The entire rend_data_t API has been moved to hs_common.{c|h} in order to
seperate code that is shared from between HS versions and unshared code (in
rendcommon.c).
