* bpo-33694: Fix typo in helper function name (GH-7522)Victor Stinner2018-06-081-1/+1
| | | | | | _feed_data_to_bufferred_proto() renamed to _feed_data_to_buffered_proto() ("bufferred" => "buffered"). Typo spotted by Nathaniel J. Smith.
* bpo-33694: Fix race condition in asyncio proactor (GH-7498)Victor Stinner2018-06-071-20/+1
| | | | | | | | | | | | | | | | The cancellation of an overlapped WSARecv() has a race condition which causes data loss because of the current implementation of proactor in asyncio. No longer cancel overlapped WSARecv() in _ProactorReadPipeTransport to work around the race condition. Remove the optimized recv_into() implementation to get simple implementation of pause_reading() using the single _pending_data attribute. Move _feed_data_to_bufferred_proto() to protocols.py. Remove set_protocol() method which became useless.
* bpo-33769: start_tls: Fix error message; cancel callbacks on error (GH-7403)Yury Selivanov2018-06-051-0/+1
| | | In addition to that, mark SSLTransport as "closed" in its "abort()" method to prevent bogus warnings.
* bpo-33734: asyncio/ssl: a bunch of bugfixes (#7321)Yury Selivanov2018-06-041-32/+29
| | | | | | | * Fix AttributeError (not all SSL exceptions have 'errno' attribute) * Increase default handshake timeout from 10 to 60 seconds * Make sure start_tls can be cancelled correctly * Make sure any error in SSLProtocol gets propagated (instead of just being logged)
* bpo-33654: Support protocol type switching in SSLTransport.set_protocol() ↵Yury Selivanov2018-05-291-4/+7

* bpo-33674: asyncio: Fix SSLProtocol race (GH-7175)Victor Stinner2018-05-281-1/+1
| | | | | | Fix a race condition in SSLProtocol.connection_made() of asyncio.sslproto: start immediately the handshake instead of using call_soon(). Previously, data_received() could be called before the handshake started, causing the handshake to hang or fail.
* bpo-33654: Support BufferedProtocol in set_protocol() and start_tls() (GH-7130)Yury Selivanov2018-05-281-1/+31
| | | | | | | | | | | In this commit: * Support BufferedProtocol in set_protocol() and start_tls() * Fix proactor to cancel readers reliably * Update tests to be compatible with OpenSSL 1.1.1 * Clarify BufferedProtocol docs * Bump TLS tests timeouts to 60 seconds; eliminate possible race from start_serving * Rewrite test_start_tls_server_1

* bpo-31399: Let OpenSSL verify hostname and IP address (#3462)Christian Heimes2018-01-271-6/+0
| | | | | | | | | | | | | | | bpo-31399: Let OpenSSL verify hostname and IP The ssl module now uses OpenSSL's X509_VERIFY_PARAM_set1_host() and X509_VERIFY_PARAM_set1_ip() API to verify hostname and IP addresses. * Remove match_hostname calls * Check for libssl with set1_host, libssl must provide X509_VERIFY_PARAM_set1_host() * Add documentation for OpenSSL 1.0.2 requirement * Don't support OpenSSL special mode with a leading dot, e.g. ".example.org" matches "www.example.org". It's not standard conform. * Add hostname_checks_common_name Signed-off-by: Christian Heimes <christian@python.org>
* bpo-29970: Make ssh_handshake_timeout None by default (#4939)Andrew Svetlov2017-12-201-1/+8
| | | | | * Make ssh_handshake_timeout None by default. * Raise ValueError if ssl_handshake_timeout is used without ssl. * Raise ValueError if ssl_handshake_timeout is not positive.

It's expected that we'll figure out the API design for starttls during 3.6, so that we can add it in 3.7.

* Issue #22560: New SSL implementation based on ssl.MemoryBIOVictor Stinner2015-01-131-0/+640
The new SSL implementation is based on the new ssl.MemoryBIO which is only available on Python 3.5. On Python 3.4 and older, the legacy SSL implementation (using SSL_write, SSL_read, etc.) is used. The proactor event loop only supports the new implementation. The new asyncio.sslproto module adds _SSLPipe, SSLProtocol and _SSLProtocolTransport classes. _SSLPipe allows to "wrap" or "unwrap" a socket (switch between cleartext and SSL/TLS). Patch written by Antoine Pitrou. sslproto.py is based on gruvi/ssl.py of the gruvi project written by Geert Jansen. This change adds SSL support to ProactorEventLoop on Python 3.5 and newer! It becomes also possible to implement STARTTTLS: switch a cleartext socket to SSL.
