IKEv2 development requires a stronger tie to the IKE SA that creates IPsec SAs. The easiest way to do this is to either expand sadb_x_kmc_t's sadb_x_kmc_cookie, or create a sadb_x_kmc_cookie64 (and have the internals deal with it completely. Per MM chat:

I'll look at the current code, and report back here.
At the bottom of that block, ipsa_kmc needs to grow.
arg3 needs to grow, and code needs to slightly change.
Slight mods here too:
And  sadb_form_query() callers need inspection.
Not that bad.
(And of course, the libipsecutil and ipseckey bits.)

Additional spelunking indicates a required change in (currently reserved) ipp_km_cookie: http://src.illumos.org/source/xref/illumos-gate/usr/src/uts/common/inet/ipsec_impl.h#220

Part of fixing this (mostly for the test suite) was to add SADB_UPDATE's ability to write into the KMC if it wasn't there already. This found a bug in KMC matching that is fixed as part of this bugfix.

Tests performed during development included the new pf_key os-tests, and running in.iked over the new kernel. I will update this ticket with final pre-IA results.

Confirmed on a fresh-today smartos-live build with these changes in place. Ran in.iked successfully, and the KMC reported by ipseckey(1M) is identical to the one pre-this-change. Also ran the new /opt/os-tests/tests/pf_key/kmc-update successfully.
