Instead of replacing connection_t.{addr,port} with a canonical
orport, and tracking the truth in real_addr, we now leave
connection_t.addr alone, and put the canonical address in
canonical_orport.
Closes #40042
Closes #33898

These names are analogous to the CONST_TO_*_CIRC() functions we have
for circuits.

This changes a LOT of code but in the end, behavior is the same.
Unfortunately, many functions had to be changed to accomodate but in majority
of cases, to become simpler.
Functions are also removed specifically those that were there to convert an
IPv4 as a host format to a tor_addr_t. Those are not needed anymore.
The IPv4 address field has been standardized to "ipv4_addr", the ORPort to
"ipv4_orport" (currently IPv6 uses ipv6_orport) and DirPort to "ipv4_dirport".
This is related to Sponsor 55 work that adds IPv6 support for relays and this
work is needed in order to have a common interface between IPv4 and IPv6.
Closes #40043.

Now instead of saying "DONE, DONE" or "MISC, MISC" or "TLS_ERROR,
TLS_ERROR", we can finally give a nice sensible "TLS_ERROR,
wrong version number" which should help debug a great deal.
Closes ticket 32622.

Previously, we would only update this field when the error happened
during a read.
This will improves our reporting for our bootstrap status, and help
to address #32622. The problem is not completely solved by this
patch, however: too many errors are still lumped into "MISC".

This one is harmless like the others (so far)

Fix a typo, and say "v3 (and later) handshake".

Log IPv6 addresses on connections where this relay is the responder.
Previously, responding relays would replace the remote IPv6 address with
the IPv4 address from the consensus.
(The port is replaced with the IPv6 ORPort from the consensus, we will
resolve this issue in 33898.)
Fixes bug 33899; bugfix on 0.3.1.1-alpha.

Consider IPv6 addresses when checking if a connection is canonical.
In 17604, relays assumed that a remote relay could consider an IPv6
connection canonical, but did not set the canonical flag on their side
of the connection.
Fixes bug 33899; bugfix on 0.3.1.1-alpha.

This is not the only relay-only handshake code, but it is most of
such code that is in connection_or.c.
|
|
There's no need to move the declarations: those were already in
ext_orport.h.
This shrinks connection_or.c a little.

Also, split the formatting code shared by control.c and
control_events.c into controller_fmt.c.

Previously, or_connection_t did not record whether or not the
connection uses a pluggable transport. Instead, it stored the
underlying proxy protocol of the pluggable transport in
proxy_type. This made bootstrap reporting treat pluggable transport
connections as plain proxy connections.
Store a separate bit indicating whether a pluggable transport is in
use, and decode this during bootstrap reporting.
Fixes bug 28925; bugfix on 0.4.0.1-alpha.

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 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.
|
|
connection_or_change_state() saved an old_state to pass to
channel_tls_handle_state_change_on_orconn(), which promptly cast it to
void. Remove this unused variable and parameter.

The main.c code is responsible for initialization and shutdown;
the mainloop.c code is responsible for running the main loop of Tor.
Splitting the "generic event loop" part of mainloop.c from the
event-loop-specific part is not done as part of this patch.

In dirauth:
* bwauth.c reads and uses bandwidth files
* guardfraction.c reads and uses the guardfraction file
* reachability.c tests relay reachability
* recommend_pkg.c handles the recommended-packages lines.
* recv_descs.c handles fingerprint files and processing incoming
routerinfos that relays upload to us
* voteflag.c computes flag thresholds and sets those thresholds on
routerstatuses when computing votes
In control:
* fmt_serverstatus.c generates the ancient "v1 server status"
format that controllers expect.
In nodelist:
* routerstatus_fmt.c formats routerstatus entries for a consensus,
a vote, or for the controller.
|
|
There are now separate modules for:
* the list of router descriptors
* the list of authorities and fallbacks
* managing authority certificates
* selecting random nodes

Existing cached directory information can cause misleadingly high
bootstrap percentages. To improve user experience, defer reporting of
directory information progress until at least one connection has
succeeded to a relay or bridge.
