5b050a9b08 This commit is an attempt to beautify the previous commit.
It creates some helper functions that return the proxy type, proxy addr/port, etc.

abe03f4943 Our warning now is much more specific, mentioning proxy type/addr/port.
Not included in the previous commit, because the implementation is
ugly; I see no other way of doing this though.

df42eb0a18 Fix unit test failure in dir/formats
options->DirPort is 0 in the unit tests, so
router_get_advertised_dir_port() would return 0 so we wouldn't pick a
dirport. This isn't what we want for the unit tests. Fixes bug
introduced in 95ac3ea594.

0e1fad648d Don't try to build descriptors when router_get_advertised_or_port()==0
The previous attempt was incomplete: it told us not to publish a
descriptor, but didn't stop us from generating one.  Now we treat an
absent OR port the same as not knowing our address.  (This means
that when we _do_ get an OR port, we need to mark the descriptor
dirty.)

More attempt to fix bug3216.

cfeafe5e77 Use a 64-bit type to hold sockets on win64.
On win64, sockets are of type UINT_PTR; on win32 they're u_int;
elsewhere they're int.  The correct windows way to check a socket for
being set is to compare it with INVALID_SOCKET; elsewhere you see if
it is negative.

On Libevent 2, all callbacks take sockets as evutil_socket_t; we've
been passing them int.

This patch should fix compilation and correctness when built for
64-bit windows.  Fixes bug 3270.

d41ac64ad6 Add UnixSocketsGroupWritable config flag
When running a system-wide instance of Tor on Unix-like systems, having
a ControlSocket is a quite handy mechanism to access Tor control
channel.  But it would be easier if access to the Unix domain socket can
be granted by making control users members of the group running the Tor
process.

This change introduces a UnixSocketsGroupWritable option, which will
create Unix domain sockets (and thus ControlSocket) 'g+rw'. This allows
ControlSocket to offer same access control measures than
ControlPort+CookieAuthFileGroupReadable.

See <http://bugs.debian.org/552556> for more details.

Nick Mathewson
61c06cbc66 Teach retry_listener about "auto" ports.
Otherwise, it will just immediately close any port declared with "auto"
on the grounds that it wasn't configured.  Now, it will allow "auto" to
match any port.

This means FWIW if you configure a socks port with SocksPort 9999
and then transition to SocksPort auto, the original socksport will
not get closed and reopened.  I'm considering this a feature.

  - 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.

dddd333a80 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.

bd7721f66e 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?)
2011-03-14 18:05:33 -04:00
Nick Mathewson
1d36a8e9ae 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.

411ec3c0f8 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.

ffd5070b04 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.
