Description

There is no handling for gateway groups in 

function openvpn_restart($mode, $settings)
. This causes an OpenVPN client to start even if the underlying vip is a CARP backup.

Recommend adding at line 792 of 

openvpn.inc
:


    /* Check if client is bound to a gateway group */    
    $a_groups = return_gateway_groups_array();
    if (is_array($a_groups[$settings['interface']])) {
        /* the interface is a gateway group. If a vip is defined and its a CARP backup then do not start */
        if (($a_groups[$settings['interface']][0]['vip'] <> "") && (get_carp_interface_status($a_groups[$settings['interface']][0]['vip']) == "BACKUP"))
            return;
    }

The fix is there. Thx. But I am still seeing some instances where OpenVPN Client is starting up when bound to a GW group with a VIP in CARP backup mode. So far have only seen this happen during bootup so it may be because of race conditions during bootup.

Let me test a couple of more times and I'll provide feedback on if this can be closed or not.

CARP will very briefly take master status while booting before reverting to backup, which is likely why. This particular issue is fixed, though for 2.2 we may want to look at improving that so the brief master status at bootup doesn't start those. You're welcome to submit a pull request on master to improve things there.
