Subject: [PATCH v4] netlink_ack: send a capped message in case of error

Hi,

After Jiri Benc feedback on my seconds proposal, please find a reworked patch still based on
Pablo Neira Ayuso proposal. Compared to v3 i have removed Cc: stable@...r.kernel.org.

Could you queue it up for -stable ?

On this patch, I found the sender's socket was saved in netlink_unicast_kernel in NETLINK_CB(skb).sk.
This information now prevent me to look up the socket for every ack.

Best Regards
Christophe
