SSL: logging levels of various errors reported with tlsfuzzer. To further differentiate client-related errors and adjust logging levels of various SSL errors, nginx was tested with tlsfuzzer with multiple OpenSSL versions (3.1.0-beta1, 3.0.8, 1.1.1t, 1.1.0l, 1.0.2u, 1.0.1u, 1.0.0s, 0.9.8zh). The following errors were observed during tlsfuzzer runs with OpenSSL 3.0.8, and are clearly client-related: SSL_do_handshake() failed (SSL: error:0A000092:SSL routines::data length too long) SSL_do_handshake() failed (SSL: error:0A0000A0:SSL routines::length too short) SSL_do_handshake() failed (SSL: error:0A000124:SSL routines::bad legacy version) SSL_do_handshake() failed (SSL: error:0A000178:SSL routines::no shared signature algorithms) Accordingly, the SSL_R_DATA_LENGTH_TOO_LONG ("data length too long"), SSL_R_LENGTH_TOO_SHORT ("length too short"), SSL_R_BAD_LEGACY_VERSION ("bad legacy version"), and SSL_R_NO_SHARED_SIGNATURE_ALGORITHMS ("no shared signature algorithms", misspelled as "sigature" in OpenSSL 1.0.2) errors are now logged at the "info" level. Additionally, the following errors were observed with OpenSSL 3.0.8 and with TLSv1.3 enabled: SSL_do_handshake() failed (SSL: error:0A00006F:SSL routines::bad digest length) SSL_do_handshake() failed (SSL: error:0A000070:SSL routines::missing sigalgs extension) SSL_do_handshake() failed (SSL: error:0A000096:SSL routines::encrypted length too long) SSL_do_handshake() failed (SSL: error:0A00010F:SSL routines::bad length) SSL_read() failed (SSL: error:0A00007A:SSL routines::bad key update) SSL_read() failed (SSL: error:0A000125:SSL routines::mixed handshake and non handshake data) Accordingly, the SSL_R_BAD_DIGEST_LENGTH ("bad digest length"), SSL_R_MISSING_SIGALGS_EXTENSION ("missing sigalgs extension"), SSL_R_ENCRYPTED_LENGTH_TOO_LONG ("encrypted length too long"), SSL_R_BAD_LENGTH ("bad length"), SSL_R_BAD_KEY_UPDATE ("bad key update"), and SSL_R_MIXED_HANDSHAKE_AND_NON_HANDSHAKE_DATA ("mixed handshake and non handshake data") errors are now logged at the "info" level. Additionally, the following errors were observed with OpenSSL 1.1.1t: SSL_do_handshake() failed (SSL: error:14094091:SSL routines:ssl3_read_bytes:data between ccs and finished) SSL_do_handshake() failed (SSL: error:14094199:SSL routines:ssl3_read_bytes:too many warn alerts) SSL_read() failed (SSL: error:1408F0C6:SSL routines:ssl3_get_record:packet length too long) SSL_read() failed (SSL: error:14094085:SSL routines:ssl3_read_bytes:ccs received early) Accordingly, the SSL_R_CCS_RECEIVED_EARLY ("ccs received early"), SSL_R_DATA_BETWEEN_CCS_AND_FINISHED ("data between ccs and finished"), SSL_R_PACKET_LENGTH_TOO_LONG ("packet length too long"), and SSL_R_TOO_MANY_WARN_ALERTS ("too many warn alerts") errors are now logged at the "info" level. Additionally, the following errors were observed with OpenSSL 1.0.2u: SSL_do_handshake() failed (SSL: error:1407612A:SSL routines:SSL23_GET_CLIENT_HELLO:record too small) SSL_do_handshake() failed (SSL: error:1408C09A:SSL routines:ssl3_get_finished:got a fin before a ccs) Accordingly, the SSL_R_RECORD_TOO_SMALL ("record too small") and SSL_R_GOT_A_FIN_BEFORE_A_CCS ("got a fin before a ccs") errors are now logged at the "info" level. No additional client-related errors were observed while testing with OpenSSL 3.1.0-beta1, OpenSSL 1.1.0l, OpenSSL 1.0.1u, OpenSSL 1.0.0s, and OpenSSL 0.9.8zh.
