Re: [PATCH net] tipc: only accept encrypted MSG_CRYPTO msgs

Hello:

This patch was applied to netdev/net.git (master)
by David S. Miller [off-list ref]:

The MSG_CRYPTO msgs are always encrypted and sent to other nodes
for keys' deployment. But when receiving in peers, if those nodes
do not validate it and make sure it's encrypted, one could craft
a malicious MSG_CRYPTO msg to deploy its key with no need to know
other nodes' keys.

This patch is to do that by checking TIPC_SKB_CB(skb)->decrypted
and discard it if this packet never got decrypted.
