* Revert "Get rid of tor_tls_block_renegotiation()."Nick Mathewson2011-12-06

* Refactor tor_event_base_once to do what we actually wantNick Mathewson2011-11-25
| | | | | This version avoids the timeout system entirely, gives a nicer interface, and lets us manage allocation explicitly.

| * Use callback-driven approach to block renegotiations.George Kadianakis2011-11-13
| | | | | | | | Also use this new approach in the bufferevents-enabled case.
| * Get rid of tor_tls_block_renegotiation().George Kadianakis2011-10-26
| | | | | | | | | | | | | | Since we check for naughty renegotiations using tor_tls_t.server_handshake_count we don't need that semi-broken function (at least till there is a way to disable rfc5746 renegotiations too).

* Record the states of failing OR connectionsNick Mathewson2011-07-11
| | | | | | | | | | | | | | | | | This code lets us record the state of any outgoing OR connection that fails before it becomes open, so we can notice if they're all dying in the same SSL state or the same OR handshake state. More work is still needed: - We need documentation - We need to actually call the code that reports the failure when we realize that we're having a hard time connecting out or making circuits. - We need to periodically clear out all this data -- perhaps, whenever we build a circuit successfully? - We'll eventually want to expose it to controllers, perhaps. Partial implementation of feature 3116.

* | | Add a testing-only option to use bufferevent_openssl as a filterNick Mathewson2010-11-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need filtering bufferevent_openssl so that we can wrap around IOCP bufferevents on Windows. This patch adds a temporary option to turn on filtering mode, so that we can test it out on non-IOCP systems to make sure it hasn't got any surprising bugs. It also fixes some allocation/teardown errors in using bufferevent_openssl as a filter.

* Make Tor work with OpenSSL 0.9.8lNick Mathewson2009-11-05
| | | | | | | | | | | | | | | | | | | To fix a major security problem related to incorrect use of SSL/TLS renegotiation, OpenSSL has turned off renegotiation by default. We are not affected by this security problem, however, since we do renegotiation right. (Specifically, we never treat a renegotiated credential as authenticating previous communication.) Nevertheless, OpenSSL's new behavior requires us to explicitly turn renegotiation back on in order to get our protocol working again. Amusingly, this is not so simple as "set the flag when you create the SSL object" , since calling connect or accept seems to clear the flags. For belt-and-suspenders purposes, we clear the flag once the Tor handshake is done. There's no way to exploit a second handshake either, but we might as well not allow it.
