Description masanari iida 2016-06-23 06:08:03 UTC 
Description of problem:
RHEL7.2

Version-Release number of selected component (if applicable):
NetworkManager-1.0.6-27.el7.x86_64

How reproducible:
Always

Steps to Reproduce:
(1) Configure bonding (mode 6)
# nmcli connection add type bond autoconnect no con-name bond0 ifname bond0 mode 6
# nmcli connection add type bond-slave autoconnect no ifname eno16777736 master bond0
# nmcli connection add type bond-slave autoconnect no ifname eno33554992 master bond0

(2) Manually change "ONBOOT=no" to "ONBOOT=yes" in
ifcfg-bond0 and ifcfg-bond-slave-eno files.

(3)Check configuration file.
Confirm no "arp_validate" option in  ifcfg-bond0 file.

# cat /etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0
TYPE=Bond
BONDING_MASTER=yes
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
NAME=bond0
UUID=f99d7a7f-4a5e-4e49-8a6a-6f8196ee2007
ONBOOT=no
BONDING_OPTS=mode=balance-alb   <== 
IPADDR=192.168.78.158
PREFIX=24
GATEWAY=192.168.78.1
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes

(4) Enable the bonding
# nmcli c mod bond0 ipv4.method manual ipv4.address "192.168.78.158/24" ipv4.gateway "192.168.78.1"

(5) After reboot,  I can find the same messages in messages.

Actual results:
bond0: option arp_validate: mode dependency failed, not supported in mode balance-alb(6)

Expected results:
No warning about arp_validate in mode=6.

nm-device-bond.c
        value = nm_setting_bond_get_option_by_name (s_bond, NM_SETTING_BOND_OPTION_ARP_VALIDATE);
        /* arp_validate > 0 only valid in active-backup mode */
        if (   value
            && g_strcmp0 (value, "0") != 0
            && g_strcmp0 (value, "none") != 0
            && g_strcmp0 (mode, "active-backup") == 0)
                set_bond_attr (device, "arp_validate", value);
        else
                set_bond_attr (device, "arp_validate", "0");    <=
