From e43700cfc08fd17b3a673b427f176e673fb3bcd5 Mon Sep 17 00:00:00 2001 From: inference Date: Tue, 17 Jan 2023 01:47:33 +0000 Subject: [PATCH] Remove FORTIFY_SOURCE since it is not compatible with or used by musl libc. Switch stack protector from all to strong since strong covers the entire practical stack smashing protection threat model. Switch -ftrivial-auto-var-init from pattern to zero since it is no longer being removed from Clang and is more suitable for hardening.
