Description Subhendu Ghosh 2010-04-02 02:59:13 UTC

Description of problem:

Backport kernel patches to support recipt of packets on real interfaces under the bonding layer:

from:
https://trac.luffy.cx/lldpd/browser/README

For bonding, you need 2.6.24 (in previous version, PACKET_ORIGDEV
affected only non multicast packets). See:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=80feaacb8a6400a9540a961b6743c69a5896b937
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=8032b46489e50ef8f3992159abd0349b5b8e476c
	
Otherwise, a packet received on a bond will be affected to all
interfaces of the bond.

On 2.6.27, we are able to receive packets on real interface for bonded
devices. This allows to get neighbor information on active/backup
bonds. Without the 2.6.27, lldpd won't receive any information on
inactive slaves. Here are the patchs (thanks to Joe Eykholt):

Version-Release number of selected component (if applicable):


How reproducible:
Always


Steps to Reproduce:
1. Install and run lldpd on RHEL5
2. 
3.
  
Actual results:

asroot_iface_init: [priv]: unable to setsockopt for master bonding device of eth3. You will get inaccurate results: Protocol not available


Expected results:
ability to send and receive lldp packets under bonding.
