I'm a mountain trill but here's some spoon feeding, https://github.com/kdave/grsecurity-patches https://seclists.org/oss-sec/2017/q2/596 .
Grsecurity is generally a mac and pax implementation and some more hardening patches, hardening is generally decreasing these abhorrent systems attack surface by maybe sacrificing speed and utility.
Mac, mandatory access controls, DOD 5200.28-STD page 20.
Pax, page exec, *bsd security(7). Known in the lisp world for breaking it but that has been worked around now.
In general /prog/rammers usually get pissed when reminded of the sorry state these systems they should own are in, completely ignoring any methods to decrease the attack surface if isn't already there. Any solutions from them are pretentious nirvana fallacies they will never get to implementing but will push on everyone else like they're retards.
All this information should help everyone in the thread given they don't know these basics.
A little more, dac is u™inx mac is multics and military like 70s os-2. This is unrelated from a lispm operating system but also from modern operating systems in general that follow a complex broken dac. Pax wasn't created by the grsecurity team but known for housing the pax team and integrating it, the migrations also aren't original to pax, it's just used for referring to a set of hardening techniques that generally have to do with pages.
