From 48be69a026b2c17350a5ef18a1959a919f60be7d Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 24 Jul 2013 00:29:18 +0100 Subject: ARM: move signal handlers into a vdso-like page Move the signal handlers into a VDSO page rather than keeping them in the vectors page. This allows us to place them randomly within this page, and also map the page at a random location within userspace further protecting these code fragments from ROP attacks. The new VDSO page is also poisoned in the same way as the vector page.
