This is something we should think about harder, but we probably want dormant
mode to be more powerful than padding in case a client has been inactive for a
day or so. After all, there are probably no circuits open at this point and
dormant mode will not allow the client to open more circuits.
Furthermore, padding should not block dormant mode from being activated, since
dormant mode relies on SocksPort activity, and circuit padding does not mess
with that.
The previous commits introduced link_specifier_dup(), which is
implemented using trunnel's opaque interfaces. So we can now
remove hs_desc_link_specifier_dup().
Cleanup after bug 22781.
The previous commits for 23576 confused hs_desc_link_specifier_t
and link_specifier_t. Removing hs_desc_link_specifier_t fixes this
confusion.
Fixes bug 22781; bugfix on 0.3.2.1-alpha.
This patch fixes a crash bug (assertion failure) in the PT subsystem
that could get triggered if the user cancels bootstrap via the UI in
TorBrowser. This would cause Tor to call `managed_proxy_destroy()` which
called `process_free()` after it had called `process_terminate()`. This
leads to a crash when the various process callbacks returns with data
after the `process_t` have been freed using `process_free()`.
We solve this issue by ensuring that everywhere we call
`process_terminate()` we make sure to detach the `managed_proxy_t` from
the `process_t` (by calling `process_set_data(process, NULL)`) and avoid
calling `process_free()` at all in the transports code. Instead we just
call `process_terminate()` and let the process exit callback in
`managed_proxy_exit_callback()` handle the `process_free()` call by
returning true to the process subsystem.

Remove router_update_info_send_unencrypted(), and move its code into the
relevant functions.
Then, re-use an options pointer.
Preparation for testing 29017 and 20918.
Remove some tiny static functions called by router_build_fresh_descriptor(),
and move their code into more relevant functions.
Then, give router_update_{router,extra}info_descriptor_body identical layouts.
Preparation for testing 29017 and 20918.
Make sure that these static functions aren't passed NULL.
If they are, log a BUG() warning, and return an error.
Preparation for testing 29017 and 20918.
Split the body of router_build_fresh_descriptor() into static functions,
by inserting function prologues and epilogues between existing sections.
Write a new body for router_build_fresh_descriptor() that calls the new
static functions.
Initial refactor with no changes to the body of the old
router_build_fresh_descriptor(), except for the split.
Preparation for testing 29017 and 20918.
When ExtraInfoStatistics is 0, stop including bandwidth usage statistics,
GeoIPFile hashes, ServerTransportPlugin lines, and bridge statistics
by country in extra-info documents.
Fixes bug 29018; bugfix on 0.2.4.1-alpha (and earlier versions).
Rewrite service_intro_point_new() to take a node_t. Since
node_get_link_specifier_smartlist() supports IPv6 link specifiers,
this refactor adds IPv6 addresses to onion service descriptors.
Part of 23576, implements 26992.
Also, when we log about a failure from base32_decode(), we now
say that the length is wrong or that the characters were invalid:
previously we would just say that there were invalid characters.
Follow-up on 28913 work.
Hope is this will make it easier to test on the live tor network.
Does not need to be merged if we don't want to, but will come in handy
for researchers.

Redefine the set of bootstrap phases to allow display of finer-grained
progress in the early connection stages of connecting to a relay.
This includes adding intermediate phases for proxy and PT connections.
Also add a separate new phase to indicate obtaining enough directory
info to build circuits so we can report that independently of actually
initiating an ORCONN to build the first application circuit.
Previously, we would claim to be connecting to a relay when we had
merely finished obtaining directory info.
Part of ticket 27167.
Replace a few invocations of control_event_bootstrap() with calls from
the bootstrap tracker subsystem. This mostly leaves behavior
unchanged. The actual behavior changes come in the next commit.
Part of ticket 27167.
Add a tracker for bootstrap progress, tracking events related to
origin circuit and ORCONN states. This uses the ocirc_event and
orconn_event publish-subscribe subsystems.
Part of ticket 27167.
Add a publish-subscribe subsystem to publish messages about changes to
origin circuits.
Functions in circuitbuild.c and circuitlist.c publish messages to this
subsystem.
Move circuit event constants out of control.h so that subscribers
don't have to include all of control.h to take actions based on
messages they receive.
Part of ticket 27167.
Add a publish-subscribe subsystem to publish messages about changes to
OR connections.
connection_or_change_state() in connection_or.c and
control_event_or_conn_event() in control.c publish messages to this
subsystem via helper functions.
Move state constants from connection_or.h to orconn_state.h so that
subscribers don't have to include all of connection_or.h to take
actions based on changes in OR connection state. Move event constants
from control.h for similar reasons.
Part of ticket 27167.
This patch adds support for the new STATUS message that PT's can emit
from their standard out. The STATUS message uses the `config_line_t` K/V
format that was recently added in Tor.
See: https://bugs.torproject.org/28846
This patch changes the LOG pluggable transport message to use the recent
K/V parser that landed in Tor. This allows PT's to specify the log
severity level as well as the message. A mapping between the PT log
severity levels and Tor's log serverity level is provided.
See: https://bugs.torproject.org/28846
