Patrick Uiterwijk 77af3a68de Fix adding the same trusted certificates multiple times (#18296) ... If there is an intermittent network failure, we might be trying to reach an URL multiple times. Without this patch, we would be re-adding the same certificate to the OpenSSL default context multiple times. Normally, this is no big issue, as OpenSSL will just silently ignore them, after registering the error in its own error stack. However, when python-cryptography initializes, it verifies that the current error stack of the default OpenSSL context is empty, which it no longer is due to us adding the certificates multiple times. This results in cryptography throwing an Unknown OpenSSL Error with details: OpenSSLErrorWithText(code=185057381L, lib=11, func=124, reason=101, reason_text='error:0B07C065:x509 certificate routines:X509_STORE_add_cert:cert already in hash table'), Signed-off-by: Patrick Uiterwijk <puiterwijk@redhat.com>		2016-11-02 10:40:48 -07:00
