commit 174c85fb469384f1c28b77cdd5a81946c0f19202
Author: Santtu Lakkala <santtu.lakkala@jolla.com>
Date: Thu Oct 17 10:42:41 2019 +0300
Fix OpenSSL private key passphrase notices
Clear error stack on successful certificate loading in
tls_ctx_load_cert_file_and_copy() and handle errors also for
PEM_read_bio_PrivateKey() call in tls_ctx_load_priv_file().
Due to certificate loading possibly leaking non-fatal errors on OpenSSL
error stack, and some slight oversights in error handling, the
>PASSWORD:Verification Failed: 'Private Key'
line was never produced on the management channel for PEM formatted keys.
