I used the following config input for openssl 3.0.3 based on my previous successes with 1.1.1m (and earlier versions) and Ivan Ristic's latest configuration: config \ --prefix=/opt/openssl-3.0.3 \ --openssldir=/opt/openssl-3.0.3 \ no-shared \ -DOPENSSL_TLS_SECURITY_LEVEL=2 \ no-ec2m \ no-rc5 \ no-idea \ enable-ec_nistp_64_gcc_128 After compiling successfully, I ran (as a normal user) "make test" and got several failures: Failed 1/3 subtests # Failed test 'Revoke certificate and generate CRL: notimes' Failed 10/15 subtests # ExpectedResult mismatch: expected Success, got ClientFail. # ExpectedResult mismatch: expected Success, got ClientFail. # ExpectedResult mismatch: expected Success, got FirstHandshakeFailed. # ExpectedResult mismatch: expected Success, got FirstHandshakeFailed. # ExpectedResult mismatch: expected Success, got ClientFail. # ExpectedResult mismatch: expected Success, got ClientFail. # ExpectedResult mismatch: expected Success, got FirstHandshakeFailed. # ExpectedResult mismatch: expected Success, got FirstHandshakeFailed. # Failed test 'running ssl_test 12-ct.cnf' Failed 1/30 subtests Failed 6/27 subtests # Failed test 'running sslapitest' Failed 1/1 subtests 60-test_x509_store.t (Wstat: 256 Tests: 3 Failed: 1) Failed test: 1 80-test_ca.t (Wstat: 256 Tests: 7 Failed: 2) Failed tests: 1, 7 80-test_ssl_new.t (Wstat: 256 Tests: 30 Failed: 1) Failed test: 12 80-test_tsa.t (Wstat: 256 Tests: 22 Failed: 1) Failed test: 1 90-test_sslapi.t (Wstat: 256 Tests: 1 Failed: 1) Failed test: 1 Note I also get similar failures with version 1.1.1o. I will file a bug with the full config dump output along with the full output of the test run if the above config input looks reasonable. Best regards, -Tom
