Re: [CentOS-devel] netlink_kernel_create() always returns NULL

2011/2/22 YANG youngyt@gmail.com:

My code fragment is below:

"nl_sk = netlink_kernel_create(16, 0, nl_data_ready, THIS_MODULE);"

It can be "make" and "insmod" correctly. But error mesage is printed into log. It indicates the netlink_kernel_create() returns NULL.

Once I change the firt parameter to another(<32 && >16), system crash when I execute insmod.

Is the protocol ID occupied? Why can't use another and how to define a new ID? I have tried to update net_link.h but fail also.

What does this have to do with the development of CentOS? If it's not related to the development of CentOS, then please use other mailing lists for such queries.
