How to receive DAD notifications in userspace

[Murali Annamneni <a.murali@xxxxxxx>]

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
