In session-based mode, rte_cryptodev_sym_session_create() allocates a session structure from the session pool, then sets sess->nb_drivers =3D pool_priv->nb_drivers, so that there wouldn't be an error. 3. In sessionless mode, get_session() in rte_openssl_pmd.c or rte_aesni_mb_pmd.c allocates a session structure from the session pool, but does not set sess->nb_drivers, causing the error. Due to this error, AESNI-MB driver segfaults in post_process_mb_job() after get_sym_session_private_data() returns NULL. OpenSSL driver can still compute SHA256 digest successfully, apart from the error message, because it does not actually use get_sym_session_private_dat= a(). --=20 You are receiving this mail because: You are the assignee for the bug.=
