Herbert Xu 92964c79b3 netlink: Fix dump skb leak/double free ... When we free cb->skb after a dump, we do it after releasing the lock. This means that a new dump could have started in the time being and we'll end up freeing their skb instead of ours. This patch saves the skb and module before we unlock so we free the right memory. Fixes: 16b304f340 ("netlink: Eliminate kmalloc in netlink dump operation.")
