ksmutil HUPs incorrect enforcerd

ods-ksmutil doesn't keep track of the configuration file passed with -c. In enforcer/utils/ksmutil.c the following code is used:

static int restart_enforcerd()
{
        /* ToDo: This should really be rewritten so that it will read
           OPENDNSSEC_ENFORCER_PIDFILE and send a SIGHUP itself */
        return system(ODS_EN_NOTIFY);
}

Here ODS_EN_NOTIFY is defined in common/config.h as

#define ODS_EN_NOTIFY "/usr/sbin/ods-control enforcer notify"

That shell script then goes and sets

configfile="/etc/opendnssec/conf.xml

from which it retrieves PID filename etc. by querying the XML.

Be that as it may, an ods-ksmutil -c my.conf will, when it is time to HUP the enforcer, HUP the wrong process.

If ksm-util at the very least exported the path to the file specified with -c, ods-control could be made to work:

setenv("ODS_CONFIGFILE", "my.conf", TRUE);

then in ods-control:

configfile=${ODS_CONFIGFILE:="/etc/opendnssec/conf.xml"}
