hi,all:
I am a newbie on linux kernel. now I encountered a problem on socket in kernel space.I create a SOCK_DGRAM socket in kernel space . What I want to do can
be described as follows:
while(1){
if( packet received)
call packet handler
}
my problem is how to know packet received at kernel space. In user space there is select() to use, but in kernel space, there is no such function.
I have read sk_buff and struct sock definition to find some hint, but still have no idea. I think it is a good place to ask for help. thanks in advance.
