I agree, so just: 
padlock_freession()
 	padlock_hash_free(ses);
  	bzero(ses, sizeof(*ses));
  	ses->ses_used = 0;
+	ses->ses_id = sid;
 	TAILQ_INSERT_HEAD(&sc->sc_sessions, ses, ses_next);

I've made some tests with ipsec and openssl on the glxsb driver (it
is quite the same code) and it looks good. 

Regards.
