I was trying to create socket within kernel and I used kernel_* helper functions to get started. This worked fine for UDP however with TCP I ran into some issues when I did the following steps
1.) I was able to create a listening TCP socket using sock_create_kern, should I be using sock_create only?
2.) I had changed the sk_data_ready callback for the listening socket so that a waiting thread would be notified when a connection is ready to be accepted. When that happened the thread was woken up and that thread then called kernel_accept.
3.) Now started the issue, in kernel_accept it uses sock_create_lite and the machine just froze. After quite a lot of hours, i was able to figure out the problem which was apparently with sock_create_lite. This function was not initializing sock->sk, printed it and found it to be NULL, which I guess caused the machine to froze.
4.) As a resolve, I went back to sock_create_kern and called sock->ops->accept instead of kernel_accept and it worked.
Is there any other step required in order to work with kernel_accept?
I'm using SLES 11 SP1, kernel 2.6.32.12
