Hi. What kind of exploit mitgations supported by the Illumos kernel?

I am thinking mitgations like KASLR, SSP, etc.

szilard: for user-space process mitigations, see illumos.org/man/7/security-flags - I don't know of a similar list for the kernel side, but I don't think there's many beyond the stuff provided by microcode like IBRS/IBPB/etc.
