* Add a test that calls tls_handshake() on a connection that has alreadyjsing2017-05-071-1/+7
| | | | | completed a TLS handshake. This should return a failure, but currently succeeds (hence the regress currently fails).

* Split TLS client/server handshake and close code into separate functionsjsing2017-05-061-4/+27

* Move TLS test code into a function that is called from main, making itjsing2017-05-062-17/+33

* Free tls_configs earlier now that we have refcounting.jsing2017-05-061-4/+4

* Use freezero() for the tls_load_file() failure case, since we'rejsing2017-05-061-4/+4
| | | | | | potentially dealing with key material. Also switch a calloc to malloc, since we immediately copy the same amount of data to the newly allocated buffer.

* Move tls_config_skip_private_key_check() out from under HIDDEN_DECLS.claudio2017-05-041-2/+4
| | | | | | Even though this is not a real public interface we need the symbol in the shared library so that relayd can use it (needed for TLS key privsep) OK beck@

Two other tricky bits with ASN1_STRING_FLAG_NDEF and BN_FLG_STATIC_DATA where the condition cannot be collapsed completely. Passes regress. ok beck

* Fix a bug caused by the return value being set early to signal successfuljsing2017-04-291-5/+5
| | | | | | | | | | | | | | | DTLS cookie validation. This can mask a later failure and result in a positive return value being returned from ssl3_get_client_hello(), when it should return a negative value to propagate the error. Ironically this was introduced in OpenSSL 2e9802b7a7b with the commit message "Fix DTLS cookie management bugs". Fix based on OpenSSL.
