key base auth fail on windows because parameter ssh ssh-agent on windows is null and the demon crashes. ssh-agent does not call auth_clear_options but it does not need to call packet_set_connection. 


void
channel_clear_permitted_opens(struct ssh *ssh)
{
	struct ssh_channels *sc = ssh->chanctxt;

	sc->permitted_opens = xrecallocarray(sc->permitted_opens,
	    sc->num_permitted_opens, 0, sizeof(*sc->permitted_opens));
	sc->num_permitted_opens = 0;
}

Please add parameter check.

	if(ssh == NULL)
		return;
