to close the connection or otherwise unlink the circuit, which makes the circuit nonactive, which invalidates the pointer from the circuit to the next circuit on the active ring. Also add a bunch of asserts, most #ifdefed out.

Add documentation for cell queue functions; make destroy cells result in cell queues getting cleared before the destroy gets sent.
svn:r9907
|
|
A surprisingly simple patch to stop reading on edge connections when their circuits get too full, and start again when they empty out. This lets us remove the logic to block begin_dir conns when the corresponding or conns get full: it was already broken by cell queues anyway.
svn:r9905
|
|
Initial version of circuit-based cell queues. Instead of hammering or_conns with piles of cells, queue cells on their corresponding circuits, and append them to the or_conn as needed. This seems to work so far, but needs a bit more work. This will break the memory-use-limitation patch for begin_dir conns: the solution will be a fun but fiddly.

Eliminate more redundant circuit_t arguments when edge_connection_t is already supplied and the circuit is already attached.
svn:r9900
|
|
Refactor a bunch of functions that take edge_connection_t not to also take a crypt_path_t; the cpath is implicit.

Make all LD_BUG log messsages get prefixed with "Bug: ". Remove manually-generated "Bug: "s from log-messages. (Apparently, we remembered to add them about 40% of the time.)

Make remap stream events have a souce; make them generated every time we get a successful connected or resolved cell. Also change reported stream target address to IP consistently when we get the IP from an exit node.
svn:r9624

|
Update copyright dates.

Report stream end events where a resolve succeeded or where we got a socks protocol error correctly, rather than calling both of them "INTERNAL". Turn ALREADY_SOCKS_REPLIED into a flag rather than a reason. This will help debug 367 part 2 a little.
svn:r9511

|
Add a REMAP state to stream events so that controllers can learn exactly when the target address for a stream has changed. May help Vidalia resolve confusions related to bug 375.

Mark a pile of XXXX comments as targetted for 0.1.2: some because they look important, some because they look easy.

New socks command CONNECT_DIR. New config option TunnelDirConns that
builds a circ ending at the directory server and delivers a BEGIN_DIR
cell if it's running 0.1.2.2-alpha or later. We still need to make
one-hop circs when appropriate, while making other conns avoid them.

Have connection_about_to_close use an end_reason field in edge_connection_t to tell what reason to tell the controller for closing the stream. Set end_reason in connection_edge_end, connection_mark_unattached_ap, and everwhere we set edge_has_sent_end. Add a changelog entry.
svn:r8779
|
|
Enable reasons for stream events in all cases but CLOSED in about_to_close_connection. That one will take a little longer.

Weasel correctly notes that we should not discard the return value from connection_exit_begin_con. Right now, the return value is always discardable, so this does not actually cause a bug, but it might later. So fix it.
svn:r8774
|
|
Fix longstanding bug in connection_exit_begin_conn(): Since connection_edge_end() exits when the connection is unattached, we were never sending RELAY_END cells back for failed RELAY_BEGIN attempts. Fix this. This might make clients that were otherwise timing out either fail faster or retry faster, which is good news for us.

[Needs review.] Add a BEGIN_DIR relay cell type for an easier
in-protocol way to connect to directory servers through Tor.
Previously, clients could only connect to director servers over Tor
from exit nodes, but couldn't get directory information anonymously
from a non-exit cache without getting a directory server involved.
This needs testing, and needs client-side code to actually exercise it.

Patch from Tup to add support for transparent AP connections: this basically bundles the functionality of trans-proxy-tor into the tor mainline. Now hosts with compliant pf/netfilter implementations can redirect TCP connections straight to Tor without diverting through SOCKS.

Refactor connection_t into edge, or, dir, control, and base subtypes. This might save some RAM on busy exit servers, but really matters most in terms of correctness.

circuit_t into origin_circuit_t and or_circuit_t. I fixed some
segaults; there may be more. We still need to move more rendezvous
stuff into subtypes.
This is a trial run for splitting up connection_t; if the approach is
insane, please say so soon so we can do something smarter.
Also, this discards the old HALF_OPEN code, which nobody seems to
want.
