Author: dteske Date: Wed Apr 8 19:12:38 2015 New Revision: 281271 URL: https://svnweb.freebsd.org/changeset/base/281271 Log: Fix a bootlock condition if/when loader_logo is set in loader.conf(5) NB: This deeply effected HardenedBSD which had a default value set. Embarassingly, I allowed the `type' primitive to be passed -1/-1 for c-addr/u stack input (the effect of which is to pull INT_MAX bytes from character address negative one in which hilarity ensues over a black screen in full-on bootlock). Much thanks to Shawn Webb [lattera] for helping me diagnose. NB: The mode-ending revisions were initially suspected (and reverted) but proved to be a red-herring. Proper mode endings will be returning.
