it looks like a pointer stored without holding a reference
for the source code in kernel version v4.14.88, and the fuction is :
ipxitf_insert_socket
static void ipxitf_insert_socket(struct ipx_interface *intrfc, struct sock *sk)
{ ipxitf_hold(intrfc);
spin_lock_bh(&intrfc->if_sklist_lock);
ipx_sk(sk)->intrfc = intrfc;
sk_add_node(sk, &intrfc->if_sklist);
spin_unlock_bh(&intrfc->if_sklist_lock);
ipxitf_put(intrfc);
}
it assigned the pointer `intrfc` to `sk->intrfc`, but didn't hold a reference
for this pointer.
it looks like a bug.....if not ,could you please explain the meaning of it?
thanks a lot！
