Description
Hello,
Looks like StrongSwan do not properly handle RFC 5996 (2.8.2).
The part where one of the peers do not detect collision (client in our case).
In that case StrongSwan closes all IKE SAs when got D INFORMATIONAL in rekey.

I've seen that occurring several times.
In my opinion, it's strongSwan's worst bug. And it hasn't received the attention from developers it deserves.

Merge branch 'exchange-collisions'
Improves the handling of IKEv2 exchange collisions in several corner
cases. TEMPORARY_FAILURE and CHILD_SA_NOT_FOUND notifies that were defined
with RFC 7296 are now handled and sent as appropriate.
The behavior in these situations is tested with new unit tests.
Fixes #379, #464, #876, #1293.
