* bpo-40094: Add test.support.wait_process() (GH-19254)Victor Stinner2020-03-311-2/+1
| | | | | | | | | Moreover, the following tests now check the child process exit code: * test_os.PtyTests * test_mailbox.test_lock_conflict() * test_tempfile.test_process_awareness() * test_uuid.testIssue8621() * multiprocessing resource tracker tests
* bpo-38614: Use test.support.SHORT_TIMEOUT constant (GH-17566)Victor Stinner2019-12-111-1/+1
| | | | | | | | | | | | | | | Replace hardcoded timeout constants in tests with SHORT_TIMEOUT of test.support, so it's easier to ajdust this timeout for all tests at once. SHORT_TIMEOUT is 30 seconds by default, but it can be longer depending on --timeout command line option. The change makes almost all timeouts longer, except test_reap_children() of test_support which is made 2x shorter: SHORT_TIMEOUT should be enough. If this test starts to fail, LONG_TIMEOUT should be used instead. Uniformize also "from test import support" import in some test files.
* bpo-38820: OpenSSL 3.0.0 compatibility. (GH-17190)Christian Heimes2019-12-071-6/+6
| | | | | | | | | | test_openssl_version now accepts version 3.0.0. getpeercert() no longer returns IPv6 addresses with a trailing new line. Signed-off-by: Christian Heimes <christian@python.org> https://bugs.python.org/issue38820
* bpo-38815: Accept TLSv3 default in min max test (GH-NNNN) (GH-17437)torsava2019-12-021-2/+8
| | | | | | | Make ssl tests less strict and also accept TLSv3 as the default maximum version. This change unbreaks test_min_max_version on Fedora 32. https://bugs.python.org/issue38815
* bpo-38275: Fix test_ssl issue caused by GH-16386 (#16428)Christian Heimes2019-09-261-0/+2

* bpo-37322: ssl test_pha_required_nocert() ignores expected SSLError (GH-14670)Victor Stinner2019-07-091-15/+18
| | | | | | test_ssl.test_pha_required_nocert() now uses support.catch_threading_exception() to ignore the expected SSLError in ConnectionHandler of ThreadedEchoServer (it is only raised sometimes on Windows).
* Revert "bpo-37322: Fix test_ssl.test_pha_required_nocert() ResourceWarning ↵Victor Stinner2019-07-091-1/+0

* bpo-37463: match_hostname requires quad-dotted IPv4 (GH-14499)Christian Heimes2019-07-021-1/+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 bug was initially found by Dominik Czarnota and reported by Paul Kehrer. Signed-off-by: Christian Heimes <christian@python.org> https://bugs.python.org/issue37463

* bpo-37428: Don't set PHA verify flag on client side (GH-14421)Christian Heimes2019-07-011-0/+31
| | | | | | | | | | | | SSLContext.post_handshake_auth = True no longer sets SSL_VERIFY_POST_HANDSHAKE verify flag for client connections. Although the option is documented as ignored for clients, OpenSSL implicitly enables cert chain validation when the flag is set.

* bpo-37069: tests use catch_unraisable_exception() (GH-13762)Victor Stinner2019-06-031-14/+18
| | | | | | | | | | | | | Modify test_coroutines, test_cprofile, test_generators, test_raise, test_ssl and test_yield_from to use support.catch_unraisable_exception() rather than support.captured_stderr(). test_thread: remove test_save_exception_state_on_error() which is now updated. test_unraisable_exception() checks that sys.unraisablehook() is called to handle _thread.start_new_thread() exception. test_cprofile now rely on unittest for test discovery: replace support.run_unittest() with unittest.main().
* bpo-34271: Add ssl debugging helpers (GH-10031)Christian Heimes2019-05-311-1/+167
| | | | | | | | | | | The ssl module now can dump key material to a keylog file and trace TLS protocol messages with a tracing callback. The default and stdlib contexts also support SSLKEYLOGFILE env var. The msg_callback and related enums are private members. The feature is designed for internal debugging and not for end users.

* 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-34605: Avoid master/slave terms (GH-9101)Victor Stinner2018-09-071-1/+1

* bpo-31432: Revert unrelated code changes to _ssl.c and test_ssl (GH-7650)Ned Deily2018-06-121-3/+1

* 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-33570: TLS 1.3 ciphers for OpenSSL 1.1.1 (GH-6976)Christian Heimes2018-05-221-29/+22
| | | | | | | | | | Change TLS 1.3 cipher suite settings for compatibility with OpenSSL 1.1.1-pre6 and newer. OpenSSL 1.1.1 will have TLS 1.3 cipers enabled by default. Also update multissltests and Travis config to test with latest OpenSSL. Signed-off-by: Christian Heimes <christian@python.org>

| | | | | | | Harden ssl module against LibreSSL CVE-2018-8970. X509_VERIFY_PARAM_set1_host() is called with an explicit namelen. A new test ensures that NULL bytes are not allowed. 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. Signed-off-by: Christian Heimes <christian@python.org>
* 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 (#5663)Christian Heimes2018-02-271-65/+94
| | | | | | | | | | | | | | | | | | * 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.

* bpo-31809: test secp ECDH curves (#4036)Christian Heimes2018-02-251-0/+52
| | | Add tests to verify connection with secp384r1 ECDH curves.
* bpo-24334: Cleanup SSLSocket (#5252)Christian Heimes2018-02-241-0/+4
| | | | | | | | | | | | | * The SSLSocket is no longer implemented on top of SSLObject to avoid an extra level of indirection. * Owner and session are now handled in the internal constructor. * _ssl._SSLSocket now uses the same method names as SSLSocket and SSLObject. * Channel binding type check is now handled in C code. Channel binding is always available. The patch also changes the signature of SSLObject.__init__(). In my opinion it's fine. A SSLObject is not a user-constructable object. SSLContext.wrap_bio() is the only valid factory.
* bpo-32819: Simplify and improve ssl.match_hostname (#5620)Christian Heimes2018-02-241-16/+49
| | | | | | | ssl.match_hostname() has been simplified and no longer depends on re and ipaddress module for wildcard and IP addresses. Error reporting for invalid wildcards has been improved. Signed-off-by: Christian Heimes <christian@python.org>
* [bpo-28414] Make all hostnames in SSL module IDN A-labels (GH-5128)Christian Heimes2018-02-241-26/+14
| | | | | | | | | | | | Previously, the ssl module stored international domain names (IDNs) as U-labels. This is problematic for a number of reasons -- for example, it made it impossible for users to use a different version of IDNA than the one built into Python. After this change, we always convert to A-labels as soon as possible, and use them for all internal processing. In particular, server_hostname attribute is now an A-label, and on the server side there's a new sni_callback that receives the SNI servername as an A-label rather than a U-label.
* bpo-28414: ssl module idna test (#5395)Christian Heimes2018-01-291-1/+65
| | | | | | | Add test cases for IDNA 2003 and 2008 host names. IDNA 2003 internationalized host names are working since bpo-31399 has landed. IDNA 2008 deviations are still broken and will be fixed in another patch. Signed-off-by: Christian Heimes <christian@python.org>
* bpo-31429: Define TLS cipher suite on build time (#3532)Christian Heimes2018-01-291-1/+15
| | | | | | | | | | | | | Until now Python used a hard coded white list of default TLS cipher suites. The old approach has multiple downsides. OpenSSL's default selection was completely overruled. Python did neither benefit from new cipher suites (ChaCha20, TLS 1.3 suites) nor blacklisted cipher suites. For example we used to re-enable 3DES. Python now defaults to OpenSSL DEFAULT cipher suite selection and black lists all unwanted ciphers. Downstream vendors can override the default cipher list with --with-ssl-default-suites.
