When psock\nis null, we can simply returning an error code, this would then trigger\nthe sk_msg_free_nocharge in the error path of __SK_REDIRECT and would have\nthe side effect of throwing an error up to user space. This would be a\nslight change in behavior from user side but would look the same as an\nerror if the redirect on the socket threw an error.\n\nThis issue can cause the following info:\nWARNING: CPU: 0 PID: 2136 at net/ipv4/af_inet.c:155 inet_sock_destruct+0x13c/0x260\nCall Trace:\n <TASK>\n __sk_destruct+0x24/0x1f0\n sk_psock_destroy+0x19b/0x1c0\n process_one_work+0x1b3/0x3c0\n worker_thread+0x30/0x350\n ? process_one_work+0x3c0/0x3c0\n kthread+0xe6/0x110\n ? kthread_complete_and_exit+0x20/0x20\n ret_from_fork+0x22/0x30\n </TASK>",
