af54a01828 Kill non-open OR connections with any data on their inbufs.
This fixes a DoS issue where a client could send so much data in 5
minutes that they exhausted the server's RAM.  Fix for bug 5934 and
6007.  Bugfix on 0.2.0.20-rc, which enabled the v2 handshake.

834654f145 Make all begindir or one-hop circuits internal
This solves bug 5283, where client traffic could get sent over the
same circuit as an anonymized connection to a directory, even if
that circuit used an exit node unsuitable for clients.  By marking
the directory connection as needs_internal, we ensure that the
(non-internal!) client-traffic connection won't be sent over the
same circuit.

9d41629aa0 Delay getsockname() call until after connect() is done
On Windows, getsockname() on a nonblocking apparently won't work
until the connection is done connecting.  On XP, it seems to fail by
reporting success and declaring that your address is INADDR_ANY.  On the
Win8 preview, though, it fails more loudly and says WSAEINVAL.

Fix for bug 5374; bugfix on 0.1.1.14-alpha.

281a5e4670 Warn and ignore the MyFamily setting if BridgeRelay is also set
Roger explains at
  http://archives.seul.org/tor/talk/Nov-2011/msg00209.html :

  "If you list your bridge as part of your family in the relay
  descriptor, then everybody can learn your bridge fingerprint, and
  they can look up your bridge's descriptor (and thus location) at
  the bridge directory authority."

Now, we can't stop relays from listing bridges, but we can warn when
we notice a bridge listing anybody, which might help some.

This fixes bug 4657; it's a fix on 0.2.0.3-alpha, where bridges were
first introduced.

6b7c3b42ee Change an assertion into a warning in connection_or_handle_event_cb()
Possibly addresses bug 4873, though IMO that's likely not a real
bug: it seems likely to have been an ssl version mismatch.

4c4dd505be Fix a hard-to-trigger memory leak in launch_resolve
To hit this leak, you need to be a relay that gets a RESOLVE request
or an exit node getting a BEGIN or RESOLVE request.  You must either
have unconfigured (and unconfigurable) nameservers, or you must have
somehow set DisableNetwork after a network request arrived but
before you managed to process it.

So, I doubt this is reached often.  Still, a leak's a leak.  Fix for
bug 5916; bugfix on 0.2.3.9-alpha and 0.1.2.1-alpha.

0bec9f320b Use %f, not %lf when formatting doubles
%f is correct; %lf is only needed with scanf.  Apparently, on some
old BSDs, %lf is deprecated.

Didn't we do this before?  Yes, we did.  But we only got the
instances of %lf, not more complicated things like %.5lf .  This
patch tries to get everything.

Based on a patch for 3894 by grarpamp.

2b6e91c2ee Report EADDRNOTAVAIL and EADDRINUSE as RESOURCELIMIT
These errors usually mean address exhaustion; reporting them as such
lets clients adjust their load to try other exits.

Fix for bug 4710; bugfix on 0.1.0.1-rc, which started using
END_STREAM_REASON_RESOURCELIMIT.

2888644a9f In connection_ap_handshake_process_socks(), mark the socks request as finished if a reply is send after a parse error
Silences the log message:
[warn] {BUG} _connection_mark_unattached_ap(): Bug: stream (marked at connection_edge.c:2224) sending two socks replies?
after the client triggered the "Tor is not an HTTP Proxy" response.

No additional socks reply was sent, though.

f89de0a79f Remove over-two-months-old entry guards even while running.
Previously, we only did this check at startup, which could lead to
us holding a guard indefinitely, and give weird results.  Fixes bug

b41dd8069f When ReloadTorrcOnSIGHUP=1, do non-reload activities anyway
Previously, we skipped everything that got invoked from
options_init_from_torrc.  But some of the stuff in
options_act_reversible and options_act is actually important, like
reopening the logs.

Now, a SIGHUP always makes the effects of an options_set() happen,
even though the options haven't changed.

Fix for bug 5095; bugfix on 0.2.1.9-alpha, which introduced
__ReloadTorrcOnSIGHUP.

edf0d5b12c Prevent an (impossible) null-pointer dereference in connection_edge_process_relay_cell
This would happen if the deliver window could become negative
because of an nonexistent connection.  (Fortunately, _that_ can't
occur, thanks to circuit_consider_sending_sendme.  Still, if we
change our windowing logic at all, we won't want this to become
triggerable.)  Fix for bug 5541.  Bugfix on 4a66865d, back from
0.0.2pre14.  asn found this.  Nice catch, asn!
