Description Paolo Abeni 2015-11-25 13:27:35 UTC 
After dumbly upgrading to rhel-7.2 from rhel-7.1 with:

yum upgrade --releasever 7.2

every time I try to establish the vpn connection to the RH intranet via nm/libreswan, the process nm-libreswan-service abort.

journalctl report:

Comment 2 Lubomir Rintel 2016-01-06 17:06:13 UTC 
A couple of issues here:

libreswan indicates failure listening on the interface (virbr0) where it should not listed. It seems errorneously marked closed now, I"ll re-send the fix: https://github.com/libreswan/libreswan/pull/42

We trust the libreswan not to do the above (which caused the connection to fail): https://git.gnome.org/browse/network-manager-openswan/commit/?h=nm-1-0&id=0d73bef35688faf442414be545e2aa0cdef10118

We clean up incorrectly (which is what caused the crash): https://git.gnome.org/browse/network-manager-openswan/commit/?h=nm-1-0&id=98ad323105c89ac0d847996653463c250aa9f12a

All fixed upstream; will be fixed with the plugin rebase with RHEL 7.3.
