Patch enabling DHCP support for internal ports none

Description IanB 2013-11-06 20:25:40 UTC 
Description of problem:

Setting a port of TYPE=OVSIntPort to use DHCP is ignored i.e. dhclient is not run for that interface

ifup-ovs script appears to only handle DHCP on TYPE=OVSBridge . Why?


How reproducible:

100%


Steps to Reproduce:

physical interface is 'p1p1' with config:

DEVICE="p1p1"
ONBOOT="yes"
DEVICETYPE="ovs"
TYPE="OVSPort"
OVS_BRIDGE="ovsbr0"
BOOTPROTO="none"
HOTPLUG="no"

bridge interface is 'ovsbr0' with config:

DEVICE="ovsbr0"
ONBOOT="yes"
DEVICETYPE="ovs"
TYPE="OVSBridge"
BOOTPROTO="none"
HOTPLUG="no"

Internet ovs port is 'mgmt0' with config:

DEVICE="mgmt0"
ONBOOT="yes"
DEVICETYPE="ovs"
TYPE="OVSIntPort"
OVSBOOTPROTO="dhcp"
OVSDHCPINTERFACES="p1p1"
OVS_BRIDGE="ovsbr0"
HOTPLUG="no"


Actual results:

I run 'systemctl start network.service' which completes without error, but interface mgmt0 never receives an IP address. Process listing shows no 'dhclient' process running.

Expected results:

dhclient should be started and 'mgmt0' should receive an IP

Additional info:

If I run 'dhclient mgmt0' manually, then 'mgmt0' receives an IP address.

ifup-ovs with dhcp support for Internal Ports

It's bug. I don't see a reason to not support it.
Could you backup the original file at
/etc/sysconfig/network-scripts/ifup-ovs

and replace with the attached one for testing purposes?

Thanks!

I've tested the attached ifup-ovs script and it works for me. Thanks!

Patch enabling DHCP support for internal ports

I've found some issues while reviewing again the previous file.

I came up another better patch which I will post upstream in a few minutes.
