Hi,

  In the example of the netlink connector code can somebody clarify if the 
coding is not right?

The buf here 
(http://lxr.linux.no/#linux+v3.0/Documentation/connector/ucon.c#L114) is 1024 
which will be cn_msg. In the nlmsghdr the buf is 
128(http://lxr.linux.no/#linux+v3.0/Documentation/connector/ucon.c#L65). 
Should the nlmsghdr be atleast bigger than the cn_msg? I understand the 
payload len being 0 and this being just an example with hardcoded values.

Thanks.
