Your -r320674 check in date: 2017-Jul-5 https://reviews.freebsd.org/D9700 was earlier and has for Diff 30173: "Update the stack guard option to new sysctl behavior": 2017-Jun-28 (The prior diff [26537] does not have the change.) 2017-Jun-28 is shortly after the hardenedbsd.org posting, not before. So it was not obvious to me that you might have influenced hardenedBSD's changes. Sounds more like full independence to me now. I do not know if you picked 2MB based on > Qualys' recommendation to use a minimum of 1MB or not. (Quoted from hardenedbsd's article.) =3D=3D=3D Mark Millard markmi at dsl-only.net
