I decided to try removing the discussed patch to see what impact it has:
Would you recommend that I revert the entire patch or just the section
relating to the "unable to install policy..." early return.
For example I'm unsure if I should revert this bit:
- tmpl->reqid = ipsec->cfg.reqid;
+ tmpl->reqid = policy->reqid;
