From 4dcddbba664cc91e2c1952498e80d8025891b9ad Mon Sep 17 00:00:00 2001 From: Bjoern Doebel Date: Wed, 9 Mar 2022 16:22:03 +0100 Subject: [PATCH] livepatch: resolve old address before function verification When verifying that a livepatch can be applied, we may as well want to inspect the target function to be patched. To do so, we need to resolve this function's address before running the arch-specific livepatch_verify hook.
