[pve-devel] random openvz veth name question ?

[Alexandre DERUMIER]

Hi,

I would like to known if we want to support firewall for random openvz veth name ?

(by the way, why do we allow to setup random name ?)


Currently, my openvz patchs hang on tap_plug (cleanup_firewall_bridge)/unplug (create_firewall_bridge_linux), because of

parse_tap_devive_name{
    if ($iface =~ m/^tap(\d+)i(\d+)$/) {
        $vmid = $1;
        $devid = $2;
    } elsif ($iface =~ m/^veth(\d+)\.(\d+)$/) {
        $vmid = $1;
        $devid = $2;
    } else {
        die "wrong interface name $iface";
    }

}


I think I can easily fix it for unfirewalled tap. (so it'll not break current setup).

but do we want to allow firewall for random name ?

create "fwln|fwbr".randomname ?  (I'm afraid of too big random name too)
