If the ip_append_data() call in icmp_push_reply() fails, ip_flush_pending_frames() needs to be called. Otherwise, ip_rt_put() is never called on inet_sk(icmp_socket->sk)->cork.rt, which prevents the route (and net_device) from ever being freed.


Your patch doesn't fit your description, the else-condition you're
adding triggers when the queue is empty, so what is the point?

Since we're only calling ip_append_data() once here, the two conditions are identical.
