* bpo-43562: fix test_ssl to skip on unreachable network (GH-24937) (GH-25047)Miss Islington (bot)2021-03-291-0/+2

* bpo-43577: Fix deadlock with SSLContext._msg_callback and sni_callback ↵Miss Islington (bot)2021-03-211-0/+22
| | | | | | | | | | | | | | | (GH-24957) OpenSSL copies the internal message callback from SSL_CTX->msg_callback to SSL->msg_callback. SSL_set_SSL_CTX() does not update SSL->msg_callback to use the callback value of the new context. PySSL_set_context() now resets the callback and _PySSL_msg_callback() resets thread state in error path.

* bpo-37463: match_hostname requires quad-dotted IPv4 (GH-14499)Miss Islington (bot)2019-07-021-1/+8
| | | | | | | | | | | | | | | | | ssl.match_hostname() no longer accepts IPv4 addresses with additional text after the address and only quad-dotted notation without trailing whitespaces. Some inet_aton() implementations ignore whitespace and all data after whitespace, e.g. '127.0.0.1 whatever'. Short notations like '127.1' for '127.0.0.1' were already filtered out.

| | | | | | | | | | | The ssl module now can dump key material to a keylog file and trace TLS protocol messages with a tracing callback.

* bpo-34759: Fix error handling in ssl 'unwrap()' (GH-9468)Nathaniel J. Smith2018-09-221-0/+41
| | | | | | | | | | | | | | | OpenSSL follows the convention that whenever you call a function, it returns an error indicator value; and if this value is negative, then you need to go look at the actual error code to see what happened. Commit c6fd1c1c3a introduced a small mistake in _ssl__SSLSocket_shutdown_impl: instead of checking whether the error indicator was negative, it started checking whether the actual error code was negative, and it turns out that the error codes are never negative. So the effect was that 'unwrap()' lost the ability to raise SSL errors. https://bugs.python.org/issue34759

* bpo-31432: Clarify ssl CERT_NONE/OPTIONAL/REQUIRED docs. (GH-3530)Christian Heimes2018-06-111-1/+3
| | | | | | | | | The documentation for CERT_NONE, CERT_OPTIONAL, and CERT_REQUIRED were misleading and partly wrong. It fails to explain that OpenSSL behaves differently in client and server mode. Also OpenSSL does validate the cert chain everytime. With SSL_VERIFY_NONE a validation error is not fatal in client mode and does not request a client cert in server mode. Also discourage people from using CERT_OPTIONAL in client mode.
* bpo-33618: Enable TLS 1.3 in tests (GH-7079)Christian Heimes2018-05-231-17/+73
| | | | | | | | | | | | TLS 1.3 behaves slightly different than TLS 1.2. Session tickets and TLS client cert auth are now handled after the initialy handshake. Tests now either send/recv data to trigger session and client certs. Or tests ignore ConnectionResetError / BrokenPipeError on the server side to handle clients that force-close the socket fd. To test TLS 1.3, OpenSSL 1.1.1-pre7-dev (git master + OpenSSL PR https://github.com/openssl/openssl/pull/6340) is required. Signed-off-by: Christian Heimes <christian@python.org>

* bpo-31453: Add setter for min/max protocol version (#5259)Christian Heimes2018-02-271-0/+117
| | | | | | | | | | | | OpenSSL 1.1 has introduced a new API to set the minimum and maximum supported protocol version. The API is easier to use than the old OP_NO_TLS1 option flags, too. Since OpenSSL has no call to set minimum version to highest supported, the implementation emulate maximum_version = MINIMUM_SUPPORTED and minimum_version = MAXIMUM_SUPPORTED by figuring out the minumum and maximum supported version at compile time.

* bpo-32951: Disable SSLSocket/SSLObject constructor (#5864)Christian Heimes2018-02-271-7/+13
| | | | | | | | | | | | | | | | Direct instantiation of SSLSocket and SSLObject objects is now prohibited. The constructors were never documented, tested, or designed as public constructors. The SSLSocket constructor had limitations. For example it was not possible to enabled hostname verification except was ssl_version=PROTOCOL_TLS_CLIENT with cert_reqs=CERT_REQUIRED. SSLContext.wrap_socket() and SSLContext.wrap_bio are the recommended API to construct SSLSocket and SSLObject instances. ssl.wrap_socket() is also deprecated. The only test case for direct instantiation was added a couple of days ago for IDNA testing. Signed-off-by: Christian Heimes <christian@python.org>

| | | | | | | | | | | | | | | | | | * bpo-32947: OpenSSL 1.1.1-pre1 / TLS 1.3 fixes Misc fixes and workarounds for compatibility with OpenSSL 1.1.1-pre1 and TLS 1.3 support. With OpenSSL 1.1.1, Python negotiates TLS 1.3 by default. Some test cases only apply to TLS 1.2. Other tests currently fail because the threaded or async test servers stop after failure. I'm going to address these issues when OpenSSL 1.1.1 reaches beta. OpenSSL 1.1.1 has added a new option OP_ENABLE_MIDDLEBOX_COMPAT for TLS 1.3. The feature is enabled by default for maximum compatibility with broken middle boxes. Users should be able to disable the hack and CPython's test suite needs it to verify default options.
