[ Upstream commit 0e74aa1d79a5bbc663e03a2804399cae418a0321 ] The syzbot found an ancient bug in the IPsec code. When we cloned a socket policy (for example, for a child TCP socket derived from a listening socket), we did not copy the family field. This results in a live policy with a zero family field. This triggers a BUG_ON check in the af_key code when the cloned policy is retrieved. This patch fixes it by copying the family field over.
