From 9a479f766be1dd777e12e3e57b6ee4c3028a40a5 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Thu, 27 Oct 2022 11:28:13 +0200 Subject: objtool: Add --cfi to generate the .cfi_sites section Add the location of all __cfi_##name symbols (as generated by kCFI) to a section such that we might re-write things at kernel boot. Notably; boot time re-hashing and FineIBT are the intended use of this.
