From 6020c0d4f64dbafcbafdffbfc67cfc5bb6b3c75c Mon Sep 17 00:00:00 2001 From: Toshio Kuratomi Date: Mon, 23 Oct 2017 13:17:04 -0700 Subject: Prefer the stdlib SSLContext over urllib3 context We do not go through the effort of finding the right PROTOCOL setting if we have SSLContext in the stdlib. So we do not want to hit the code that uses PROTOCOL to set the urllib3-provided ssl context when SSLContext is available. Also, the urllib3 implementation appears to have a bug in some recent versions. Preferring the stdlib version will work around that for those with Python-2.7.9+ as well. Fixes #26235 Fixes #25402 Fixes #31998 (cherry picked from commit 725ae96e1bb7790cec4a56a9a8a9c5bcb3182951) --- lib/ansible/module_utils/urls.py | 12 +++++++++--- 1 file changed, 9 insertions(+), 3 deletions(-) diff --git a/lib/ansible/module_utils/urls.py b/lib/ansible/module_utils/urls.py index 92ebf5a0a6..38c2007611 100644 --- a/lib/ansible/module_utils/urls.py +++ b/lib/ansible/module_utils/urls.py @@ -680,10 +680,13 @@ class SSLValidationHandler(urllib_request.BaseHandler): return True def _make_context(self, to_add_ca_cert_path): - if HAS_URLLIB3_PYOPENSSLCONTEXT: + if HAS_SSLCONTEXT: + context = create_default_context() + elif HAS_URLLIB3_PYOPENSSLCONTEXT: context = PyOpenSSLContext(PROTOCOL) else: - context = create_default_context() + raise NotImplementedError('Host libraries are too old to support creating an sslcontext') + if to_add_ca_cert_path: context.load_verify_locations(to_add_ca_cert_path) return context @@ -692,8 +695,11 @@ class SSLValidationHandler(urllib_request.BaseHandler): tmp_ca_cert_path, to_add_ca_cert_path, paths_checked = self.get_ca_certs() https_proxy = os.environ.get('https_proxy') context = None - if HAS_SSLCONTEXT or HAS_URLLIB3_PYOPENSSLCONTEXT: + try: context = self._make_context(to_add_ca_cert_path) + except Exception: + # We'll make do with no context below + pass # Detect if 'no_proxy' environment variable is set and if our URL is included use_proxy = self.detect_no_proxy(req.get_full_url()) -- cgit v1.2.1
