| | * | | | Add a missing cast to silence the compiler | Sebastian Hahn | 2011-03-28 |
| | * | | | Fix some 'impossible' overflow bugs in byte counting•••The first was genuinely impossible, I think: it could only happen
when the amount we read differed from the amount we wanted to read
by more than INT_MAX.
The second is just very unlikely: it would give incorrect results to
the controller if you somehow wrote or read more than 4GB on one
edge conn in one second. That one is a bugfix on 0.1.2.8-beta.

| | * | | | Triage the XXX022 and XXX021 comments remaining in the code•••Remove some, postpone others, leave some alone. Now the only
remaining XXX022s are ones that seem important to fix or investigate.

| * | | | | Add a missing ! to the check for CountPrivatebandwidth. | Nick Mathewson | 2011-04-06 |
| * | | | | Tweaks to Cagara's CountPrivateBandwidth patch:••• - Document it in the manpage
- Add a changes entry
- No need to log when it is set: we don't log for other options.
- Use doxygen to document the new flag.
- Test truth of C variables with "if (x)", not "if (x == 1)".
- Simplify a complex boolean expression by breaking it up.

| | * | | | | Implement server side of Proposal 174 (optimistic data)•••Ian's original message:
The current code actually correctly handles queued data at the
Exit; if there is queued data in a EXIT_CONN_STATE_CONNECTING
stream, that data will be immediately sent when the connection
succeeds. If the connection fails, the data will be correctly
ignored and freed. The problem with the current server code is
that the server currently drops DATA cells on streams in the
EXIT_CONN_STATE_CONNECTING state. Also, if you try to queue data
in the EXIT_CONN_STATE_RESOLVING state, bad things happen because
streams in that state don't yet have conn->write_event set, and so
some existing sanity checks (any stream with queued data is at
least potentially writable) are no longer sound.
The solution is to simply not drop received DATA cells while in
the EXIT_CONN_STATE_CONNECTING state. Also do not send SENDME
cells in this state, so that the OP cannot send more than one
window's worth of data to be queued at the Exit. Finally, patch
the sanity checks so that streams in the EXIT_CONN_STATE_RESOLVING
state that have buffered data can pass.
[...] Here is a simple patch. It seems to work with both regular
streams and hidden services, but there may be other corner cases
I'm not aware of. (Do streams used for directory fetches, hidden
services, etc. take a different code path?)

| | | * | | | | Consider sending stream-level SENDME cells on partial flushes.•••Right now, we only consider sending stream-level SENDME cells when we
have completely flushed a connection_edge's outbuf, or when it sends
us a DATA cell. Neither of these is ideal for throughput.
This patch changes the behavior so we now call
connection_edge_consider_sending_sendme when we flush _some_ data from
an edge outbuf.
Fix for bug 2756; bugfix on svn r152.

| | * | | | Add client code to detect attempts to connect to 127.0.0.1 etc•••We detect and reject said attempts if there is no chosen exit node or
circuit: connecting to a private addr via a randomly chosen exit node
will usually fail (if all exits reject private addresses), is always
ill-defined (you're not asking for any particular host or service),
and usually an error (you've configured all requests to go over Tor
when you really wanted to configure all _remote_ requests to go over
Tor).
This can also help detect forwarding loop requests.
Found as part of bug2279.

| * | | | Convert bufferevents to use rate-limiting.•••This requires the latest Git version of Libevent as of 24 March 2010.
In the future, we'll just say it requires Libevent 2.0.5-alpha or
later.
Since Libevent doesn't yet support hierarchical rate limit groups,
there isn't yet support for tracking relayed-bytes separately when
using the bufferevent system. If a future version does add support
for hierarchical buckets, we can add that back in.
