Neil Horman 682fd21afb Detect and prevent recursive config parsing ... If a malformed config file is provided such as the following: openssl_conf = openssl_init [openssl_init] providers = provider_sect [provider_sect] = provider_sect The config parsing library will crash overflowing the stack, as it recursively parses the same provider_sect ad nauseum. Prevent this by maintaing a list of visited nodes as we recurse through referenced sections, and erroring out in the event we visit any given section node more than once. Note, adding the test for this revealed that our diagnostic code inadvertently pops recorded errors off the error stack because provider_conf_load returns success even in the event that a configuration parse failed. The call path to provider_conf_load has been updated in this commit to address that shortcoming, allowing recorded errors to be visibile to calling applications.
