These macros create both a QCryptoTLSCertReq object which must be deinitialized and also an on-disk certificate file. The migration test currently removes the on-disk file in test_migrate_tls_x509_finish() but never deinitializes the QCryptoTLSCertReq, which means that memory allocated as part of it is leaked: Indirect leak of 2 byte(s) in 1 object(s) allocated from: #0 0x5558ba33712e in malloc (/mnt/nvmedisk/linaro/qemu-from-laptop/qemu= /build/asan/tests/qtest/migration-test+0x22f12e) (BuildId: 4c8618f663e53853= 8cad19d35233124cea161491) #1 0x7f64afc131f4 (/lib/x86_64-linux-gnu/libtasn1.so.6+0x81f4) (BuildI= d: 2fde6ecb43c586fe4077118f771077aa1298e7ea) #2 0x7f64afc18d58 in asn1_write_value (/lib/x86_64-linux-gnu/libtasn1.s= o.6+0xdd58) (BuildId: 2fde6ecb43c586fe4077118f771077aa1298e7ea) #3 0x7f64af8fc678 in gnutls_x509_crt_set_version (/lib/x86_64-linux-gnu= /libgnutls.so.30+0xe7678) (BuildId: 97b8f99f392f1fd37b969a7164bcea884e23649= b) #4 0x5558ba470035 in test_tls_generate_cert tests/unit/crypto-tls-x509-= helpers.c:234:5 #5 0x5558ba464e4a in test_migrate_tls_x509_start_common tests/qtest/mig= ration-test.c:1058:5 #6 0x5558ba462c8a in test_migrate_tls_x509_start_default_host tests/qte= st/migration-test.c:1123:12 #7 0x5558ba45ab40 in test_precopy_common tests/qtest/migration-test.c:1= 786:21 #8 0x5558ba450015 in test_precopy_unix_tls_x509_default_host tests/qtes= t/migration-test.c:2077:5 #9 0x5558ba46d3c7 in migration_test_wrapper tests/qtest/migration-helpe= rs.c:456:5 (and similar reports). The only function currently provided to deinit a QCryptoTLSCertReq is test_tls_discard_cert(), which also removes the on-disk certificate file. For the migration tests we need to retain the on-disk files until we've finished running the test, so the simplest fix is to provide a new function test_tls_deinit_cert() which does only the cleanup of the QCryptoTLSCertReq, and call it in the right places.
