Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec
Steffen Klassert says: ==================== 1) Build fix for ip_vti when NET_IP_TUNNEL is not set. We need this set to have ip_tunnel_get_stats64() available. 2) Fix a NULL pointer dereference on sub policy usage. We try to access a xfrm_state from the wrong array. 3) Take xfrm_state_lock in xfrm_migrate_state_find(), we need it to traverse through the state lists. 4) Clone states properly on migration, otherwise we crash when we migrate a state with aead algorithm attached. 5) Fix unlink race when between thread context and timer when policies are deleted. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
