Description Tomas Smetana 2008-11-07 12:54:14 UTC 
Description of problem:
The rdisc utility issues an error and fails to start if it's run on system with an interface having two IP addresses assigned to it.

Version-Release number of selected component (if applicable):
iputils-20020927-45

How reproducible:
always

Steps to Reproduce:
1. ifconfig eth0 192.168.1.1 netmask 255.255.255.0
2. ifconfig eth0:0 192.168.2.1 netmask 255.255.255.0
3. rdisc -fs
  
Actual results:
The following errors appear in /var/log/messages:

Nov  7 12:52:18 localhost in.rdiscd[4860]: setsockopt (IP_ADD_MEMBERSHIP): Address already in use
Nov  7 12:52:18 localhost in.rdiscd[4860]: Failed joining addresses

and rdisc doesn't start.

Expected results:

Proposed patch

The patch tries to solve the problem by remembering indexes of the interfaces which have been already joined to the multicast group and skipping any attemt to join twice the interface with the same index.
