Hello,

After doing some research I've noticed that FBSD is pretty much the only
*BSD system without support for some sort of W^X policy.
Also said policy is implemented in HardenedBSD which looks pretty much
similar to FBSD.
Would there be interest in reviewing/merging a patch that imports W^X
(PAGEEXEC and MPROTECT) from HardenedBSD?
I suppose that it would have to be disabled by default, as it breaks some
things such as JIT.

Regards
Kornel Dulęba
