Hi all,
I am using a module that employs netlink functions and data.
After compiling it, I insert the module as:
# insmod test.ko
but the terminal (prompt) gets locked. After debugging the module, I
noticed that skb_recv_datagram() is responsible for that.
Take a look the snippet of the code:
skb = skb_recv_datagram(nl_sk, 0, 0, &err);
if (!skb) {
printk(KERN_ERR
"netlink_test: skb_recv_datagram!\n");
return;
}
When I interrupt the prompt (as it was locked by inserting the module)
typing <Control>+C, the message "netlink_test: skb_recv_datagram!" is
printed, so I wonder why this is happening.
Is it normal skb_recv_datagram() blocks the terminal? How can I solve
it?
BR,
Mauricio Lin.
