When dn_neigh.c was converted from kmalloc to kzalloc in commit
0da974f4f3 it was missed that
dn_neigh_seq_open was actually clearing the allocation twice was
missed.

Fix the selection of an SA for an outgoing packet to be at the same
context as the originating socket/flow. This eliminates the SELinux
policy's ability to use/sendto SAs with contexts other than the socket's.
With this patch applied, the SELinux policy will require one or more of the
following for a socket to be able to communicate with/without SAs:
1. To enable a socket to communicate without using labeled-IPSec SAs:
allow socket_t unlabeled_t:association { sendto recvfrom }
2. To enable a socket to communicate with labeled-IPSec SAs:
allow socket_t self:association { sendto };
allow socket_t peer_sa_t:association { recvfrom };

Fix SO_PEERSEC for tcp sockets to return the security context of
the peer (as represented by the SA from the peer) as opposed to the
SA used by the local/source socket.

Since the upstreaming of the mlsxfrm modification a few months back,
testing has resulted in the identification of the following issues/bugs that
are resolved in this patch set.
1. Fix the security context used in the IKE negotiation to be the context
of the socket as opposed to the context of the SPD rule.
2. Fix SO_PEERSEC for tcp sockets to return the security context of
the peer as opposed to the source.
3. Fix the selection of an SA for an outgoing packet to be at the same
context as the originating socket/flow.
The following would be the result of applying this patchset:
- SO_PEERSEC will now correctly return the peer's context.
- IKE deamons will receive the context of the source socket/flow
as opposed to the SPD rule's context so that the negotiated SA
will be at the same context as the source socket/flow.
- The SELinux policy will require one or more of the
following for a socket to be able to communicate with/without SAs:
1. To enable a socket to communicate without using labeled-IPSec SAs:
allow socket_t unlabeled_t:association { sendto recvfrom }
2. To enable a socket to communicate with labeled-IPSec SAs:
allow socket_t self:association { sendto };
allow socket_t peer_sa_t:association { recvfrom };
This Patch: Pass correct security context to IKE for use in negotiation
Fix the security context passed to IKE for use in negotiation to be the
context of the socket as opposed to the context of the SPD rule so that
the SA carries the label of the originating socket/flow.

Weirdness: the third argument of socket() is net-endian
here. Oh, well - it's documented in packet(7).
