Unable to create netlink socket in centos

[Nikesh Kumar Mahalka]

Hi,
I am using a CentOS Linux release 7.0.1406 (Core)
I  am using kernel version 3.10.0-123.el7.x86_64

When i am creating a netlink socket,it is getting failed.
int sock_fd = socket(PF_NETLINK, SOCK_RAW, 1)
 value of sock_fd is -1


When i was using 3.1 kernel version of CentOS,above socket function was working.
I want to create netlink socket on kernel version 3.10.0


Any help will be greatly admired.

Regards
NIkesh
