SSL: logging levels of errors observed with tlsfuzzer and LibreSSL. As tested with tlsfuzzer with LibreSSL 3.7.0, the following errors are certainly client-related: SSL_do_handshake() failed (SSL: error:14026073:SSL routines:ACCEPT_SR_CLNT_HELLO:bad packet length) SSL_do_handshake() failed (SSL: error:1402612C:SSL routines:ACCEPT_SR_CLNT_HELLO:ssl3 session id too long) SSL_do_handshake() failed (SSL: error:140380EA:SSL routines:ACCEPT_SR_KEY_EXCH:tls rsa encrypted value length is wrong) Accordingly, the SSL_R_BAD_PACKET_LENGTH ("bad packet length"), SSL_R_SSL3_SESSION_ID_TOO_LONG ("ssl3 session id too long"), SSL_R_TLS_RSA_ENCRYPTED_VALUE_LENGTH_IS_WRONG ("tls rsa encrypted value length is wrong") errors are now logged at the "info" level.
