Herbert Xu 57b26930c7 netlink: Fix dump skb leak/double free [ Upstream commit `92964c79b3` ] 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.")
