How to receive DAD notifications in userspace

[Murali Annamneni]

Hi,

I'm trying to  retrieve DAD(duplicate address detection) notifications in userspace using netlink sockets.

The code snippet is -
struct sockaddr_nl addr;
sock = socket(PF_NETLINK, SOCK_RAW, NETLINK_ROUTE)
addr.nl_family = AF_NETLINK;
addr.nl_groups = RTMGRP_IPV6_IFADDR;

I'm receiving notifications when an ipv6 address added/deleted for an interface.
But I'm not receiving any notifications when the address is in tentative state(dadfailed)
I think I have to play with members of struct sockaddr_nl by setting proper values to receive notifications properly.

Can anyone please tell me what's wrong in my code .


Thanks & Regards
