 Module Name:   src
 Committed By:  spz

 Modified Files:
        src/sys/net: pfkeyv2.h
        src/sys/netipsec: key.c
        src/sys/netkey: key.c
 Log Message:
 fix two bugs in the PFKEY interface:
 1) RFC2367 says in 2.3.3 Address Extension: "All non-address
    information in the sockaddrs, such as sin_zero for AF_INET sockaddrs,
    and sin6_flowinfo for AF_INET6 sockaddrs, MUST be zeroed out."
    the IPSEC_NAT_T code was expecting the port information it needs
    to be conveyed in the sockaddr instead of exclusively by
    and was not zeroing out the port information in the non-nat-traversal
    Since it was expecting the port information to reside in the sockaddr
    it could get away with (re)setting the ports after starting to use them.
    -> Set the natt ports before setting the SA mature.
 2) RFC3947 has two Original Address fields, initiator and responder,
    so we need SADB_X_EXT_NAT_T_OAI and SADB_X_EXT_NAT_T_OAR and not just
 The change has been created using vanhu's patch for FreeBSD as reference.
 Note that establishing actual nat-t sessions has not yet been tested.
